Description
Technical Field
[0001] This utility model relates to the field of machine tool guideway technology, and specifically to a machine tool guideway protection mechanism. Background Technology
[0002] Machine tool guideways are core components in machine tools used to support and guide moving parts to move precisely along a specific trajectory. Their performance directly determines the machining accuracy, stability, and lifespan of the machine tool. Machine tool guideway protection devices are specialized protective systems installed on machine tool guideways, mainly used to isolate external contaminants and mechanical impacts, ensuring stable guideway accuracy and extending service life. Their design must take into account sealing performance, dynamic response capability, and environmental adaptability, making them an indispensable core component of modern high-precision machine tools.
[0003] Most common machine tool guideway protection mechanisms are folding protective covers. The gaps in the folding protective covers are easily invaded by fine chips, which accumulate and form hard particles that can easily scratch the surface of the guideway. Moreover, the folding protective covers are often highly integrated with the guideway system, and replacing the cover requires removing adjacent components, which is troublesome and affects the utilization rate of the machine tool. Utility Model Content
[0004] This utility model provides a machine tool guideway protection mechanism that solves the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0006] An embodiment of this utility model provides a machine tool guideway protection mechanism, comprising:
[0007] The system comprises a displacement element, a base, and two guide rail bodies, wherein the two guide rail bodies are fixedly connected to the surface of the base, and the displacement element is slidably connected to the surface of the two guide rail bodies.
[0008] The self-cleaning protection device comprises two pairs of devices respectively disposed on the surfaces of two guide rail bodies. Each self-cleaning protection device includes a first airflow gate, a first protective cover, a second airflow gate, a second protective cover, a fixing block, a storage box, and an air pump. The first airflow gate is slidably connected to the surface of the guide rail body. The first airflow gate is fixedly connected to one end of the first protective cover, and the other end of the first protective cover is fixedly connected to the second airflow gate. The second airflow gate is fixedly connected to one end of the second protective cover, and the other end of the second protective cover is fixedly connected to the fixing block. The fixing block is bolted to the guide rail body. An air pump is fixedly connected to both the first and second airflow gates. Airflow channels are provided inside both the first and second airflow gates. Multiple through holes are provided on the surfaces of both the first and second airflow gates. Inlets are provided on both sides of the guide rail body. A second sliding groove is provided on the surface of the guide rail body. The storage box is detachably installed on the inner wall of the guide rail body.
[0009] Through the above technical solution, by setting up a self-cleaning protection device, during the displacement process of the displacement component, the air pump blows away the debris that has entered the protective cover through the airflow gate, which is attached to the surface of the guide rail body. The debris will slide into the inlets on both sides of the guide rail body through the inclined plate and finally fall into the storage box, thus achieving the self-cleaning function. This solves the problem of debris entering the protective cover and forming hard particles that scratch the guide rail. The operator can remove the bolts to detach the fixing block from the guide rail body and pull the fixing pin to detach the first airflow gate from the displacement component, thereby quickly achieving the overall disassembly of the self-cleaning protection device. This solves the problem of troublesome disassembly and the impact on machine tool utilization.
[0010] Furthermore, the self-cleaning protection device also includes a dovetail tenon, which is fixedly connected to the first airflow door. The surface of the displacement member is provided with a groove, and the size of the dovetail tenon is adapted to the groove of the displacement member. A fixing pin is slidably connected to the inner wall of the displacement member. The surface of the dovetail tenon is provided with a hole, and the size of the fixing pin is adapted to the size of the hole of the dovetail tenon.
[0011] The above technical solution, through the cooperation of dovetail tenon and fixing pin, achieves the fixation of the first airflow valve and displacement component.
[0012] Furthermore, a pull block is fixedly connected to one end of the fixing pin, a spring is sleeved on the arc surface of the fixing pin, one end of the spring is fixedly connected to the pull block, and the other end of the spring is fixedly connected to the displacement component.
[0013] The above technical solution uses a spring to allow for quick insertion and removal of the fixing pin, and also to fix the fixing pin to the displacement component.
[0014] Furthermore, two pairs of mounting brackets are fixedly connected to the surfaces of the first airflow door and the second airflow door, and each pair of mounting brackets is rotatably connected to a roller. Two first sliding grooves are opened on the surface of the guide rail body, and the size of the roller is adapted to the size of the first sliding groove.
[0015] The above technical solution allows the first and second airflow gates to slide back and forth easily by setting rollers.
[0016] Furthermore, inclined plates are fixedly connected to both sides of the guide rail body, a second handle is fixedly connected to the surface of the storage box, and a sealing gasket is fixedly connected to the surface of the first airflow door.
[0017] The above technical solution allows debris to slide into the storage box by setting an inclined plate, preventing debris from remaining on the guide rail body. The second handle makes it easy to pull out the storage box, and the sealing gasket ensures a seal between the first airflow valve and the displacement component, preventing debris from entering.
[0018] Furthermore, a rotating shaft is fixedly connected to the surface of the guide rail body, a rotating plate is rotatably connected to the arc surface of the rotating shaft, a lead screw is threadedly connected to the inner wall of the rotating plate, a first handle is fixedly connected to one end of the lead screw, and a pressure plate is fixedly connected to the other end of the lead screw.
[0019] The above technical solution allows the storage box to be fixed by turning the screw through a pressure plate.
[0020] Furthermore, the inner wall of the fixing block is detachably fitted with bolts, the surface of the guide rail body is provided with holes, the size of the bolts is adapted to the size of the holes in the guide rail body, and the threaded surface of the bolts is threaded with nuts.
[0021] The above technical solution allows for the fixing of the fixing block to the guide rail body using bolts.
[0022] The above-described solution of this utility model has at least the following beneficial effects:
[0023] 1. This utility model, by setting a self-cleaning protection device, allows for the removal of debris that intrudes into the protective cover during the displacement process of the displacement component. The air pump blows away the debris adhering to the surface of the guide rail body through the through hole of the airflow gate. The debris slides into the inlets on both sides of the guide rail body through the inclined plate and finally falls into the storage box, thus achieving the self-cleaning function. This solves the problem of debris intruding into the protective cover and forming hard particles that scratch the guide rail. The operator can remove the bolts to detach the fixing block from the guide rail body and pull the fixing pin to detach the first airflow gate from the displacement component, thereby quickly achieving the overall disassembly of the self-cleaning protection device. This solves the problem of troublesome disassembly and the impact on machine tool utilization. Attached Figure Description

[0032] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0033] like Figures 1 to 6 As shown, an embodiment of this utility model provides a machine tool guide rail protection mechanism, including: a displacement member 1, a base 2 and two guide rail bodies 3, the two guide rail bodies 3 being fixedly connected to the surface of the base 2, and the displacement member 1 being slidably connected to the surface of the two guide rail bodies 3.
[0034] Two pairs of self-cleaning protection devices 4 are respectively disposed on the surfaces of the two guide rail bodies 3. Each self-cleaning protection device 4 includes a first airflow gate 401, a first protective cover 402, a second airflow gate 403, a second protective cover 404, a fixing block 405, a storage box 406, and an air pump 413. The first airflow gate 401 is slidably connected to the surface of the guide rail body 3. The first airflow gate 401 is fixedly connected to one end of the first protective cover 402, and the other end of the first protective cover 402 is fixedly connected to the second airflow gate 403. The second airflow gate 403 is fixedly connected to one end of the second protective cover 404. The other end of the second protective cover 404 is fixedly connected to the fixing block 405. The fixing block 405 is connected to the guide rail body 3 by bolts 407. The first airflow door 401 and the second airflow door 403 are both fixedly connected to air pumps 413. The interior of the first airflow door 401 and the second airflow door 403 is provided with airflow channels 415. The surfaces of the first airflow door 401 and the second airflow door 403 are provided with multiple through holes 416. The sides of the guide rail body 3 are provided with inlets 425. The surface of the guide rail body 3 is provided with second sliding grooves 428. The storage box 406 is detachably installed on the inner wall of the guide rail body 3.
[0035] By setting up a self-cleaning protection device 4, during the displacement of the displacement component 1, debris that intrudes into the protective cover will be blown away by the air pump 413 through the airflow gate through the through hole 416 on the surface of the guide rail body 3. The debris will slide into the inlet 425 on both sides of the guide rail body 3 through the inclined plate 426 and finally fall into the storage box 406, thus achieving the self-cleaning function. This solves the problem of debris intruding into the protective cover and forming hard particles that scratch the guide rail. The operator can remove the bolt 407 to make the fixing block 405 detach from the guide rail body 3, and pull the fixing pin 412 to make the first airflow gate 401 detach from the displacement component 1, thereby quickly achieving the overall disassembly of the self-cleaning protection device 4, solving the problem of troublesome disassembly and affecting the utilization rate of the machine tool.
[0036] It should be noted that the first protective cover 402 and the second protective cover 404 are made of nylon-based composite material (tensile strength ≥80MPa, oil temperature range -30℃~120℃), and the first airflow valve 401 and the second airflow valve 403 are made of hard anodized aluminum alloy.
[0037] like Figures 3 to 6As shown, the self-cleaning protection device 4 also includes a dovetail tenon 414, which is fixedly connected to the first airflow gate 401. A groove is formed on the surface of the displacement member 1, and the size of the dovetail tenon 414 matches the size of the groove in the displacement member 1. A fixing pin 412 is slidably connected to the inner wall of the displacement member 1. A hole is formed on the surface of the dovetail tenon 414, and the size of the fixing pin 412 matches the size of the hole in the dovetail tenon 414. Through the cooperation of the dovetail tenon 414 and the fixing pin 412, the first airflow gate 401 and the displacement member 1 are fixedly fixed. A pull block 410 is fixedly connected to one end of the fixing pin 412, and a spring 4 is sleeved on the arc surface of the fixing pin 412. 11. One end of the spring 411 is fixedly connected to the pull block 410, and the other end of the spring 411 is fixedly connected to the displacement member 1. Through the spring 411, on the one hand, the fixing pin 412 can be quickly inserted and removed, and on the other hand, the fixing pin 412 can be fixed on the displacement member 1. Two pairs of mounting brackets 417 are fixedly connected to the surfaces of the first airflow gate 401 and the second airflow gate 403. Each pair of mounting brackets 417 is rotatably connected to a roller 418. Two first sliding grooves 427 are opened on the surface of the guide rail body 3. The size of the roller 418 is adapted to the size of the first sliding groove 427. By setting the roller 418, the first airflow gate can be easily... The first airflow valve 401 and the second airflow gate 403 slide back and forth. Inclined plates 426 are fixedly connected to both sides of the guide rail body 3. A second handle 424 is fixedly connected to the surface of the storage box 406. A sealing gasket 409 is fixedly connected to the surface of the first airflow gate 401. By setting the inclined plates 426, debris can slide into the storage box 406, preventing debris from remaining on the guide rail body 3. The second handle 424 facilitates the pulling of the storage box 406. The sealing gasket 409 ensures a seal between the first airflow gate 401 and the displacement member 1, preventing debris from entering. A rotating shaft 419 is fixedly connected to the surface of the guide rail body 3, and the arc surface of the rotating shaft 419 rotates. A rotating plate 420 is connected, and a lead screw 422 is threadedly connected to the inner wall of the rotating plate 420. One end of the lead screw 422 is fixedly connected to a first handle 421, and the other end of the lead screw 422 is fixedly connected to a pressure plate 423. By setting the pressure plate 423, the storage box 406 can be fixed by turning the lead screw 422. A bolt 407 is detachably installed on the inner wall of the fixing block 405. Holes are opened on the surface of the guide rail body 3. The size of the bolt 407 is adapted to the size of the hole in the guide rail body 3. A nut 408 is threadedly connected to the threaded surface of the bolt 407. The fixing block 405 and the guide rail body 3 can be fixed by the bolt 407.
[0038] In this embodiment of the invention, during machine tool operation, the displacement component 1 moves back and forth on the guide rail body 3 of the base 2. During this movement, it drives the self-cleaning protection device 4 to move back and forth as well. The first protective cover 402 and the second protective cover 404 will experience stretching and compression. Over time, fine chips will penetrate into the self-cleaning protection device 4. The sealing gasket 409 between the displacement component 1 and the first airflow gate 401 will reduce the amount of chip intrusion. The air pump 413 automatically starts by detecting the motion signal through the Hall sensor built into the displacement component 1. The airflow will flow along the first airflow gate 401 and the second airflow gate 403. Airflow channel 415 discharges from through hole 416, blowing debris off the guide rail body 3. With the cooperation of displacement component 1, the entire guide rail body 3 is cleaned. The blown debris falls onto inclined plate 426, then slides into inlet 425 and falls into storage box 406. The operator can rotate screw 422 on rotating plate 420 through first handle 421 to prevent pressure plate 423 from contacting storage box 406. Then, rotate rotating plate 420 along rotating shaft 419 so that it does not obstruct the movement of storage box 406. The storage box 406 in second slide groove 428 can be pulled out through second handle 424 to clean up the debris.
[0039] Workers can unscrew nut 408 to pull bolt 407 out of the inner wall of fixing block 405 and guide rail body 3, thereby detaching fixing block 405 from guide rail body 3. By pulling pull block 410, fixing pin 412 is pulled out from the inner wall of dovetail tenon 414. At this time, spring 411 is in a stretched state. Then, pull first airflow valve 401 to disengage dovetail tenon 414 from the groove of displacement member 1, thereby detaching first airflow valve 401 from the fixation of displacement member 1. Then, slide self-cleaning protection device 4. At this time, roller 418 on mounting bracket 417 will roll along first sliding groove 427, sliding self-cleaning protection device 4 out of guide rail body 3 as a whole, thus completing the disassembly of self-cleaning protection device 4.
[0040] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
