[0031] Specifically, when the guide rail needs to be machined, the numerical control bed plate is disassembled as a whole, the bed body is completely exposed, then the guide rail is precisely installed on the bed body by the forklift, after installation, the device is powered on, professional tools are used to measure the table, and the headstock and tailstock boundary parts are adjusted until they are parallel, then the position of the grinding wheel 5 is adjusted to achieve slight contact with the bed surface to be ground, then the numerical control equipment is operated, and after completion, the automatic program is started, and the grinding wheel 5 starts to grind the bed body;

[0032] In the process of adjusting the position of the grinding wheel 5, first start the second servo motor 12, the second servo motor 12 drives the second ball screw 19 to rotate through the linkage mechanism 11, the linkage mechanism 11 is composed of synchronous belt and synchronous wheel, because the mounting plate 9 is connected with the second ball screw 19 by thread, the rotation of the second ball screw 19 will drive the mounting plate 9 to move up and down on the slide 17 stably, so as to adjust the height of the first grinding head motor 4 and the second grinding head motor 6 flexibly, to meet the grinding requirements of different height guide rails, in addition, by rotating the first screw 14 manually, the first adjusting block 7 connected with it by thread moves transversely on the mounting plate 9, and then drives the second grinding head motor 6 to move synchronously, when rotating the second screw 15 manually, the second adjusting block 16 moves transversely on the mounting plate 9, and pushes the first grinding head motor 4 to move synchronously, if it is needed to adjust the position of the grinding wheel 5 more finely, by rotating the first adjusting screw 8 manually, the first fixed block 20 moves up and down in the first adjusting block 7 linearly, and drives the second grinding head motor 6 to realize fine position adjustment, by rotating the second adjusting screw 13 manually, the second fixed block 21 moves up and down in the second adjusting block 16 linearly, and then drives the first grinding head motor 4 to realize fine transverse position adjustment, to realize the independent fine adjustment of the two grinding wheels 5;

[0033] When the position of the grinding wheel 5 is adjusted, the first grinding head motor 4 and the second grinding head motor 6 are started, the output end of which drives the grinding wheel 5 to rotate at high speed, and the efficient grinding of the guide rail is started, in this process, the oil pump 18 continuously provides good lubrication and cooling effect for the whole system, to ensure the normal operation of each moving part, and effectively reduces the heat generated in the grinding process, it sucks lubricating oil from the oil tank of the equipment through a special oil suction port, and the lubricating oil is pressurized in the oil pump 18, and then is delivered to each key moving part of the equipment through a series of oil pipes, because the oil pump 18 belongs to the existing mature public technology, its specific structure and working principle will not be described here, at the same time, the first servo motor 10 is started, the output end of which drives the first ball screw 3 to rotate, because the slide 17 is connected with the first ball screw 3 by thread, and the lower end inside the slide 17 slides outside the two roller tracks 2, the stability of the movement of the slide 17 is improved, the rotation of the first ball screw 3 will make the slide 17 move linearly along the roller track 2 stably, so as to drive the grinding wheel 5 to move accurately on the surface of the grinding machine;

[0034] Only need to disassemble numerical control bedplate, can carry out processing, greatly shorten the preparation time, improve the overall processing efficiency, reduce the labor cost and labor intensity, through the second servo motor 12, linkage mechanism 11 and second ball screw 19, can conveniently adjust the height of grinding wheel 5, can adapt to different specifications and wear condition of guide rail, enhance the versatility and applicability of grinding machine, avoid the problem of frequent replacement of equipment or complex debugging due to the height difference of guide rail, also can be through the first screw rod 14, second screw rod 15, first adjusting screw rod 8 and second adjusting screw rod 13, realize the coarse adjustment and fine adjustment of the horizontal position of grinding wheel 5, this kind of multi-dimensional adjustment mode can meet the grinding requirements of guide rail at different positions and different accuracy, ensure the high precision and high quality of grinding processing, effectively improve the product qualification rate, the first screw rod 14, second screw rod 15, first adjusting screw rod 8 and second adjusting screw rod 13 of manual adjustment can be replaced by motor control, realize completely automatic operation, improve the processing precision and intelligent level.

[0035] Working principle: when the guide rail needs to be processed, only need to disassemble the numerical control bedplate, expose the bed body, then install the guide rail free disassembly grinding machine on the bed body through the forklift, then power on the equipment and measure the table, make the headstock and tailstock boundary part parallel, then adjust the position of grinding wheel 5 to make it slightly contact with the ground surface, then tool the numerical control equipment, then run the automatic program to realize the grinding processing of the bed body;

[0036] In the adjustment process, first start the second servo motor 12, drive the second ball screw 19 to rotate through the linkage mechanism 11, because the mounting plate 9 is threadedly connected with the second ball screw 19, the rotation of the second ball screw 19 makes the mounting plate 9 move up and down linearly on the sliding block 17, thereby adjusting the height of the first grinding head motor 4 and the second grinding head motor 6 to adapt to the grinding requirements of guide rails with different heights, also can rotate the first screw rod 14, the first adjusting block 7 threadedly connected with the first screw rod 14 will move horizontally on the mounting plate 9, make the second grinding head motor 6 move synchronously, when the second screw rod 15 rotates, the second adjusting block 16 will move horizontally on the mounting plate 9, promote the first grinding head motor 4 to move synchronously, thereby realizing the adjustment of the horizontal position of the grinding head, when rotating the first adjusting screw rod 8, the first fixed block 20 will move up and down linearly in the first adjusting block 7, thereby driving the second grinding head motor 6 to make more fine position adjustment, when rotating the second adjusting screw rod 13, the second fixed block 21 will move up and down linearly in the second adjusting block 16, thereby driving the first grinding head motor 4 to make more fine horizontal position adjustment, realize the independent fine adjustment of the first grinding head motor 4 and the second grinding head motor 6;

[0037] When the positions of the first grinding head motor 4 and the second grinding head motor 6 are adjusted, the grinding wheel 5 is driven to rotate, the guide rail is ground, the oil pump 18 can provide lubrication and cooling for the whole system, the normal operation of each moving part is ensured, and the heat generation in the grinding process is reduced, at the same time, the first servo motor 10 is started, and the output end drives the first ball screw 3 to rotate, since the sliding block 17 is threadedly connected with the first ball screw 3, and the lower end inside the sliding block 17 slides outside the two roller tracks 2, the rotation of the first ball screw 3 drives the sliding block 17 to move linearly along the roller tracks 2, so that the grinding wheel 5 moves on the surface of the guide rail.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
