In the whole process of moving the machine to do a full inspection before moving, move according to the plan, after moving to accurately recover the accuracy and function of the machine tool. With the continuous development of urban planning and industrial skills, many industrial enterprises have encountered issues such as the moving of factories and the aging of equipment. In particular, large-scale manufacturing companies are relatively versatile in three types of large-scale metal cutting equipment: boring mills, vertical lathes, and floor-standing boring and milling machines. Due to their complex equipment structure, and related parts and volumes, they are very difficult to move. of. This article has carried on the comprehensive analysis to the characteristics of large-scale machine moving process. 1. The process of moving a large machine tool The moving process of large-scale machine tools requires a tacit understanding of mechanical and electrical cooperation. The entire process of moving the mechanical part of the process are: before dismantling check, disassemble before power off, disassemble after power off and move and then install the four steps. The first part of the electrical process includes: electrical preparation before dismantling, electrical disassembly after power off, wiring after moving and power on, etc. 2. Contents of requirements inspection prior to dismantling a moving machine Before shutting down the power, it is necessary to check the actual condition of the machine tool, which mainly includes six items: (1) Check the original inspection sheet, accuracy standards, and skill conditions of moving machine tools, and understand the precision and parameters of the machine when it leaves the factory. It is advisable to investigate the machining conditions of the machine tool, as shown in Figure 1. For reference when adjusting accuracy after moving. (2) Check the accuracy of the machine before dismantling and prepare for reinstalling the machine. Qualified parts must be rehabilitated according to the original accuracy when they are reinstalled, and unqualified parts need to be adjusted when they are installed. (3) Measure the relevant scale under the working conditions of moving machine tools, and the scale to be measured includes: According to the actual operation conditions of the machine tool, measure the exposed scale or thickness of each component. About the Gantry mobile boring and milling machine and the floor-type boring mill, the two machine tools should measure the azimuth of the column and the outer edge of the carriage, and make records so that the orientation can be adjusted when reinstalling. With regard to the change of the column before and after the boring and milling head is removed from the floor boring and milling machine, the gantry boring and milling machine shall measure the change of the column before and after the beam is removed. In general, as long as the machine tool is based on the characteristics of the machine, carefully measuring the process accuracy of the important surface of the machine tool to ensure that the machine after the move can be accurately recovered to the practical operating conditions. (4) The mover should be fully familiar with the function of the machine tool, including the spindle speed (highest, lowest and speed, etc.), the coordinate operation status and multi-coordinate linkage function. (5) Moving personnel needs to carefully inspect the condition of the oil, water, and gas systems of the machine tool and the direction of the pipeline. Based on the actual operating conditions of the machine tool, the various system pressure values ​​are recorded to facilitate the rehabilitation of the machine tool after moving. (6) Referring to the original packing list of the moved machine tool, do a good job of the component dismantling plan and reduce the parts as much as possible to prevent loss. When relocating, it is necessary to conclude that the parts other than the machine main unit are to be transported at random, and the person who made the box prepares the packing box. 3. Disassemble before power off Before turning off the power to prepare for dismantling, it is necessary to make a detailed analysis of the moving machine tool in order to do the following: 1) The unrelated wall guarding and craft bending shall be removed from the machine. 2 Divide the protection of the bed, columns and beams early and stack them at the ends or in the direction of easy lifting. 3 If the boring and milling heads of the floor boring and milling machine and the cross beam components of the gantry boring and milling machine have weights, the hammers need to be strung in the column with bars to relax the hammer chains. 4 Position the boring and milling head, beam and other components in an orientation, and the lower part must have necessary support. 5 When cranes are moved at the site where the machine is being moved, the cranes must be paid attention to the gantry structure of the gantry mobile boring and milling machine or the ram column of the floor boring and milling machine. The parking space corresponds to the factory space. 6 Before the power off, the electromechanical personnel should stop the line removal after executing the machine condition together. 4. Problems that need to be paid attention to when the power is turned off Disassemble after power off is one of the points in the entire moving operation. When disassembling the machine, pay attention to the order of dismantling. To do this: 1. The cooperation of the mechanical and electrical personnel will divide all the drag chains of the machine tool. The mechanical personnel served as the differentiation of oil, water, and gas lines, and the electrical personnel assumed the differentiation of the cables, as shown in Figure 2. 2 Remove all rail protection from the machine when disassembling. 3 Remove the console and console of the machine tool. 4 When the removed machine tool has robots, guide rails, and magazines, it is necessary to carefully investigate things, see patterns, and analyze them. It is better to remove the whole robot or magazine for reinstallation. 5 Machine weights with counterweight removed. 6 When you remove the beam, slide plate and other components, pay attention to the linear scale maintenance of the scale. 7 Remove the column and other components to pay attention to the direction of the flip. 8 When removing the relevant parts such as the bed, it is decided whether the bed and the related feed box will be differentiated according to the actual situation. The final removal of the chip remover, the anchor screw and the horn and other finishing inspection and packing. Once the parts are damaged and related problems are discovered during the entire disassembly process, they should be promptly reflected to all the machine tools and negotiated. 5. Reload the machine after moving the machine After the moving of the machine, it is the final step in the entire moving operation. It is also a crucial step. Then, pay attention to four points when installing the machine: (1) When the machine tool is reinstalled, the joints of the components, the guide rails, the strips, the pressure plate, etc. The appearance of the moving parts must be “inquired†with oilstone to prevent scratching and rusting. The important parts such as the bed and the like are required to be mounted on the new machine, as shown in Fig. 3. 2 Before the reinstallation, clean all removed roll bodies according to the requirements for cleaning the bearings, and add the smooth grease according to the instructions. 3 If belt-driven parts are used, the belts should be numbered before they are disassembled. When reinstalled, they should be arranged by number. 4 When adjusting the setting, adjust it according to the value recorded at the time of removal. 6. Electrical preparation before dismantling (1) Before disassemble the machine, read the electrical schematics, wiring diagrams, hydraulic diagrams and other related drawings of the machine tool, as well as the operating instructions and other documents, so that the motors, valves, induction switches, limit switches, etc. Components and maps correspond one by one. (2) As much as possible to understand the machine tool's operating method and the existing function of the machine tool. (3) Make a backup of NC data and PLC program. (4) Check the labels of all electrical components on the machine tool and should be common with the drawings. (5) Check the status of components in the panel. (6) Power off measures the electrical resistance of certain electrical components and circuits, such as power supply loads, valves, brakes, and motors, so that after the wiring is recovered in the future, check for short circuit and open circuit. 7. The main process of electrical disassembly after moving the machine out of power (1) Turn all the machine parts to the detachable position, and then disassemble the machine after being recognized by the machine. (2) The numbered symbols on all electrical components, cables, and wires must be clarified, and the disconnection must be recorded. 8 wiring and power after the machine moves (1) According to the records of the disassembled machine, check the internal resistance of the machine's electrical components before power-on, and check the line according to the function to ensure that the wiring is correct. (2) Energize in the normal power-on sequence: control circuit, main circuit, NC data and PLC program. (3) Necessary conditions for operation according to each coordinate: After commissioning of the pump set, pressure adjustment and smoothness, etc., the coordinate adjustments can be started after the mechanical person approves. If you have rotating coordinates, you should know the scale of rotation, especially when debugging, do not break the cables and tubing.
