Description

Technical Field

[0001] The invention relates to the field of machine tool guide rail pairs, and in particular to a maintenance and processing device for a numerically controlled machine tool guide rail pair. Background Art

[0002] The parts that support and guide the moving components to move along a certain trajectory are called guide rails, and are often referred to as guide rails. The trajectory of the moving parts can be straight, circular or curved. The guide rail is a very important component in the machine, especially in the machine tool. The machining accuracy of the machine tool is directly related to the accuracy of the guide rail. For precision machine tools produced in small batches, the machining workload of the guide rail accounts for about 40% of the entire machine tool machining workload. Moreover, once the guide rail is damaged, it is very difficult to repair.

[0003] There are many types of CNC machine tool guide rails, the most typical of which are linear screw guides and linear ball guides. Linear screw guides convert rotary motion into linear motion mainly through the cooperation of screws and nuts. Linear ball guides use rolling steel balls to circulate between the guide rails and guide blocks to achieve high-precision linear motion.

[0004] Linear screw guides are prone to wear and increase errors during specific use, and linear ball guides usually need maintenance and precision calibration after a certain period of use. In particular, when the linear ball guide is removed, in order to ensure that the balls in the slider will not fall off, it is necessary to align the dummy shaft and the slide rail in advance, and then directly transfer the slider from the slide rail to the dummy shaft. The dummy shaft cannot be removed in advance during installation, and the slider must be completely slid onto the slide rail before the dummy shaft can fall off freely, which causes great inconvenience to the disassembly and installation of the linear ball slide. Moreover, linear ball guides and linear screw guides usually need to be calibrated again during maintenance due to wear. Currently, this is basically done manually without any auxiliary devices, which greatly increases the difficulty of operation and reduces maintenance efficiency. Therefore, a CNC machine tool guide pair maintenance and processing device is proposed. ‌‌‌‌ Summary of the invention

[0015] Preferably, the cross plate fits and contacts with the lower end surfaces of the supporting middle platform and the supporting side platforms.

[0016] Compared with the related art, the CNC machine tool guide rail pair maintenance processing device provided by the present invention has the following beneficial effects:

[0017] First, place the linear ball guide pair on the supporting middle platform, and then through the contraction of the telescopic rod three, pull the small extrusion seat and the large extrusion seat on the connecting rods on both sides closer to each other, so as to squeeze and clamp the clamping table and the slide rails on both sides respectively. When the large extrusion seat is stably clamped on both sides of the slide rail, the connecting rod will no longer move. At this time, the small extrusion seat stops squeezing the clamping table, that is, drives the mounting plate to slide a certain distance on the guide slide rod, and stops after stretching the tension spring three to a certain extent. Since the clamping table is coplanar with the dummy shaft, and the small extrusion seat is coplanar with the large extrusion seat, the dummy shaft can be in a state of being coplanar with the side of the slide rail, and the stability of the linear ball guide pair is guaranteed.

[0018] The guide rail is driven downward by the telescopic rod two, so that the pressure plate presses the linear ball guide pair tightly and firmly, and at the same time drives the push rod to move downward, drives the inclined slides on both sides to approach each other, and gradually pushes the false shaft slide rails on the inclined slide to fit together, and then the guide rail drives the guide blocks on both sides to slide away from each other, and drives the pressure plate to slide on the surface of the linear ball guide pair, and first fits and squeezes the limit plate by squeezing the guide plate to squeeze the limit plate, thereby driving the slide frame to move downward, and compressing the spring two, so that the limit plate coplanar with the upper end face of the false shaft can be coplanar with the upper end face of the slide rail shaft, and then the upper end face of the false shaft is coplanar with the upper end face of the slide rail shaft, so as to achieve the state of complete coincidence between the false shaft and the slide rail axis, and then the continued sliding of the guide block will drive the pressure plate and the shift block to gradually push the slider from the slide rail to the false shaft, so as to realize the removal operation.

[0019] By extending the telescopic rod three times, the small extrusion seat and the large extrusion seat on the connecting rods on both sides are driven to move away from each other, and the cross plate is driven to move up at the same time. The upward movement of the cross plate will push the supporting middle platform and the supporting side platform to rise to the same height, which is convenient for placing the removed linear ball guide or linear screw guide to calibrate the linear ball guide or linear screw guide. Then, the disc and the guide rail are driven to rotate by the driving motor, so that the guide rail can be rotated to be parallel to the linear ball guide or linear screw guide placed on the supporting middle platform and the supporting side platform, so as to perform auxiliary maintenance on the linear ball guide or linear screw guide.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] See also Figure 1-Figure 9 The present invention provides a technical solution: a CNC machine tool guide rail pair maintenance processing device, comprising a processing table 1, a support frame 2 is connected to the processing table 1, and a supporting middle platform 3 is also slidably connected to the processing table 1, and a linear ball guide pair 4 composed of a base 401, a slide rail 402, and a slider 403 is placed on the supporting middle platform 3, such as Figure 3As shown, the supporting middle platform 3 is located in the center of the processing platform 1, and the supporting frame 2 is installed in the front and back center of the processing platform 1, and the upper end of the supporting frame 2 is open.

[0033] A plurality of telescopic rods 5 are installed on the support frame 2, and a slide rod seat 17 is connected to both sides of the processing table 1. A slide guide mechanism is slidably arranged on the slide rod seat 17, and the slide guide mechanism is used to guide the slide 403 sliding on the slide rail 402 downward.

[0034] The slider guide mechanism includes an inclined slide 19, a slide rod seat 20, a guide sleeve 21, a slide frame 23, a mounting plate 26, and a dummy shaft 27. The inclined slide 19 is slidably connected to the outer side of the slide rod seat 17, the slide rod seat 20 is connected to the two side surfaces of the inclined slide 19, the guide sleeve 21 is slidably sleeved on the outer side of the slide rod seat 20, the slide frame 23 is connected to the guide sleeve 21 on both sides of the same inclined slide 19, the two side surfaces of the slide frame 23 are symmetrically connected with the guide slide rod 24, the mounting plate 26 is slidably sleeved on the outer side of the guide slide rod 24, the dummy shaft 27 is installed on the mounting plate 26 by bolts, and one side of the dummy shaft 27 is also connected to a clamping table 28, and the two sides of the slide frame 23 are connected with limit plates 29.

[0035] by Figure 5 For example, the slide frame 23 can slide up and down on the slide rod seat 20 through the guide sleeve 21. The slide frame 23 is also clamped on the outside of the inclined slide 19, which further increases the stability of the slide frame 23 when sliding up and down. At the same time, the mounting plate 26 can slide on the outside of the guide slide rod 24, and then can be adjusted so that the front and rear mounting plates 26 can slide closer to or away from each other with the slide frame 23 as the boundary. The inclined slides 19 on both sides can also slide on their respective slide rod seats 17, so that the inclined slides 19 on the left and right sides can slide closer to or away from each other.

[0036] Since the dummy shaft 27 is mounted on the mounting plate 26 by bolts, when facing linear ball guide rail pairs 4 of different specifications and sizes, the sizes of the slide rails 402 thereon may be different, and the dummy shaft 27 of the corresponding size can also be flexibly replaced.

[0037] The upper end surfaces of the sliding frame 23, the limiting plate 29 and the dummy shaft 27 are at the same height, the side surfaces of the clamping table 28 and the dummy shaft 27 are in the same plane, and the guide sleeve 21 slides in a limited manner in accordance with the surface of the inclined slide table 19, so that after the dummy shaft 27 is installed on the mounting plate 26 by bolts, the upper end of the dummy shaft 27 can be kept at the same height as the sliding frame 23 and the limiting plate 29 thereon, and the side surfaces of the dummy shaft 27 can also be kept coplanar with the clamping table 28, making the guide sleeve 21 more stable when sliding up and down.

[0038] A spring 18 is sleeved on the outer side of the slide bar seat 17, and the two ends of the spring 18 are respectively connected to the slide bar seat 17 and the inclined slide 19; a spring 22 is sleeved on the outer side of the slide bar seat 20, and the two ends of the spring 22 are respectively connected to the slide bar seat 20 and the guide sleeve 21; a tension spring 3 25 is sleeved on the outer side of the guide slide bar 24, and the two ends of the tension spring 3 25 are respectively connected to the guide slide bar 24 and the mounting plate 26, so that the inclined slides 19 on both sides can compress the spring 18 after sliding under the action of external force to obtain restoring force; when the slide frame 23 moves downward under the action of external force, the spring 22 can also be compressed by the guide sleeve 21 to obtain restoring force; and when the front and rear mounting plates 26 are squeezed by external force and approach each other, the tension spring 3 25 will be stretched, and the restoring force is also obtained.

[0039] A slideway 30 is provided on the processing table 1, and a clamping mechanism is arranged in the slideway 30 for clamping the linear ball guide pair 4 placed on the processing table 1. The clamping mechanism includes a limit block 31, a telescopic rod 32, a cross plate 33, and a connecting rod 35. The limit block 31 is slidably connected in the slideway 30, the telescopic rod 32 is connected to the processing table 1, and the cross plate 33 is connected to the telescopic rod 32. A rotating plate 34 is rotatably connected to each limit block 31, and the other end of the rotating plate 34 is rotatably connected to the cross plate 33. The limit block 31 is connected to a connecting rod 35 above the processing table 1, and a small extrusion seat 36 and a large extrusion seat 37 are connected at both ends of the connecting rod 35. The small extrusion seat 36 is in contact with the side of the limit plate 29, and the small extrusion seat 36 and the large extrusion seat 37 are in the same plane. The large extrusion seat 37 is in contact with the side of the slide rail 402, and a sliding sleeve passing through the processing table 1 is provided with a supporting side table 40.

[0040] by Figure 1 and Figure 5 For example, the cross plate 33 can be pulled down by contracting the telescopic rod three 32, thereby driving the rotating plate 34 to rotate, pulling the limit blocks 31 and the connecting rod 35 on the front and rear sides closer to each other, and driving the small extrusion seat 36 and the large extrusion seat 37 on the front and rear sides closer to each other, until the large extrusion seat 37 is fitted and clamped with the slide rail 402. During this process, the small extrusion seat 36 will also push the limit plate 29 and the mounting plate 26 to move on the guide slide rod 24, and stretch the tension spring three 25, so that the limit plate 29, the false shaft 27 and the side of the slide rail 402 are coplanar.

[0041] A toggle mechanism is commonly provided on the multiple telescopic rods 5, and the toggle mechanism is used to toggle the slider 403 on the slide rail 402. The toggle mechanism includes a disc 7, a telescopic rod 2 8, a slide rod seat 3 11, a pressure plate 12, a toggle block 14, and a push rod 42. A drive motor 6 is commonly connected to the multiple telescopic rods 5, the disc 7 is connected to the output end of the drive motor 6, the telescopic rod 2 8 is connected to the lower end surface of the disc 7, and the lower end of the telescopic rod 2 8 is connected to a guide rail 9, and the guide rail 9 is symmetrically The guide block 10 is slidably connected to the guide block 10, the slide rod seat three 11 is connected to the lower end of the guide block 10, the pressure plate 12 is slidably sleeved on the outer side of the slide rod seat three 11, the shift block 14 is connected to the lower end of the pressure plate 12, and the sides of the pressure plates 12 on both sides that are away from each other are both installed with extrusion guide plates 15 by bolts, and the extrusion guide plate 15 slides in contact with the upper end surface of the limit plate 29, the push rod 42 is connected to both sides of the guide rail 9, and the lower end of the push rod 42 slides in contact with the inclined surface of the inclined slide 19.

[0042] The guide rail 9 can be driven to move up and down by extending and retracting the telescopic rod 15, so that it can pass through the opening at the upper end of the support frame 2 and move to the upper and lower sides of the support frame 2 respectively. The guide rail 9 can also be driven to move up and down by extending and retracting the telescopic rod 28. When moving down, the pressure plate 12 will first press the upper end of the slide rail 402, and then as the guide rail 9 continues to move downward, it will drive the push rod 42 to contact the inclined slide 19, and appropriately bring the inclined slides 19 on both sides closer to each other, and compress the spring 18, so that the false shafts 27 on both sides are close to each other and gradually contact the two ends of the slide rail 402.

[0043] A spring four 13 is sleeved on the outer side of the slide rod seat three 11, and the two ends of the spring four 13 are respectively connected to the pressure plate 12 and the guide block 10, so that when the pressure plate 12 is pressed against the slide rail 402, the pressure plate 12 will slide upward on the slide rod seat three 11 and compress the spring four 13. When the pressure plate 12 cancels the pressure on the slide rail 402, under the action of its own gravity and the spring four 13, the pressure plate 12 will automatically move down to the lowest position of the slide rod seat three 11.

[0044] One end of the extrusion guide plate 15 is inclined, and a plurality of mounting bolt holes 16 are provided on the pressure plate 12 and the extrusion guide plate 15. A slideway 2 41 is provided on the processing table 1, and the slide rod seat 3 11 is slidably connected in the slideway 2 41, so that when the guide rail 9 drives the guide block 10 to slide, the guide block 10 will synchronously drive the pressure plate 12, which is already in a pressed state with the slide rail 402, to slide in contact with the upper end of the slide rail 402, and then the extrusion guide plate 15 on one side of the pressure plate 12 will gradually contact with the limit plate 29. When the upper end surface of the limit plate 29 is higher than the slide rail 402, it will gradually be pressed down to the same height as the slide rail 402, so that the upper end surface of the dummy shaft 27 is also the same height as the slide rail 402 at this time, and the elastic force of the control spring 4 13 here is greater than the spring 22, which can effectively ensure that the limit plate 29 and the dummy shaft 27 are squeezed to the same height as the slide rail 402 by the extrusion guide plate 15.

[0045] The arrangement of the second slideway 41 can ensure that the slide rod seat 3 11 will not conflict with the processing table 1 when following the guide rail 9 to move downward, and can slide in the second slideway 41 .

[0046] In this way, since the side surface of the dummy shaft 27 is coplanar with the side surface of the slide rail 402, and the upper end surface of the dummy shaft 27 is also coplanar with the upper end surface of the slide rail 402 through the action of the squeezing guide plate 15, as the guide block 10 continues to move to both sides, the slider 403 will be driven by the shift block 14 to slide from the slide rail 402 to the dummy shaft 27, thereby realizing the operation of flexibly removing the slider 403 on the linear ball guide pair 4 without manual work, thereby greatly improving the operating efficiency and facilitating subsequent maintenance and processing.

[0047] Furthermore, since a plurality of mounting bolt holes 16 are provided on the extrusion guide plate 15 , cleaning cotton wipes can be installed on the mounting bolt holes 16 so that the guide block 10 can slide left and right in the guide rail 9 to clean and wipe the slide rail 402 .

[0048] Embodiment 2:

[0049] See also Figure 1-Figure 9 The present invention provides a technical solution: an opening 38 is opened on the processing table 1, and openings 39 are opened on both sides of the opening 38, the supporting middle table 3 slides through the opening 38, the supporting side table 40 slides through the opening 39, and the cross plate 33 fits and contacts with the lower end surfaces of the supporting middle table 3 and the supporting side table 40.

[0050] by Figure 1 and Figure 5For example, when the linear ball guide or the linear screw guide needs to be repaired, the telescopic rod 32 can be controlled to extend, thereby driving the cross plate 33 to move upward and pushing the small extrusion seats 36 and the large extrusion seats 37 on both sides away from each other. As the cross plate 33 rises, the supporting middle platform 3 and the supporting side platform 40 can be gradually pushed upward and higher than the small extrusion seat 36 and the large extrusion seat 37, making it convenient to place the linear ball guide or the linear screw guide on the supporting middle platform 3 and the supporting side platform 40 for processing.

[0051] The guide rail 9 can also be driven to rotate by the driving motor 6, and then the guide rail 9 can be rotated from a perpendicular state to the supporting middle platform 3 and the supporting side platform 40 to a parallel state. Then, the relevant cleaning components or calibration instruments can still be installed on the pressure plate 12 or the extrusion guide plate 15 through the mounting bolt holes 16 to perform relevant maintenance on the worn linear ball guide or linear screw guide.
