Description

Technical Field

[0001] This invention relates to the field of machine tool cleaning technology, specifically to a machine tool track cleaning device. Background Technology

[0002] Machine tool tracks require regular cleaning or timely maintenance based on the degree of contamination, which helps extend the service life of the machine tool tracks and gantry, and ensures the gantry's movement accuracy. The upper surface of the machine tool track has a row of downward-extending slots at its center. These slots typically serve two functions: first, they are used to bolt the machine tool track to the CNC machine tool base, with the bolts sinking into the slots; second, after the bolts are installed, the slots are filled with a grease-like lubricant to lubricate the sliding of the gantry on the machine tool track. Contamination of the machine tool track mainly comes from dust settling and metal filings splashing during machining. Both the surface of the machine tool track and the lubricant in the slots become contaminated. During machine operation, the sliding of the gantry on the machine tool track further scrapes dust and metal filings from the track surface into the lubricant in the slots. Therefore, in addition to cleaning the track surface, the lubricant needs to be replaced periodically.

[0003] Currently, the main methods for cleaning machine tool tracks involve brushing the track surface with a cleaning brush and using a special scoop to remove lubricant from the grooves. This is rather cumbersome and not very efficient. Specialized machine tool rail cleaning devices have been invented in the industry, providing convenience to some extent. For example, Chinese patent CN220215859U discloses "A guide rail cleaning device for CNC machine tools used in industrial product processing," which includes an upper pressure frame and a lower pressure frame. The lower pressure frame is fixedly attached to the bottom of the upper pressure frame. An upper sponge block and a lower sponge block are respectively fixed in the grooves of the upper and lower pressure frames. Perforations are provided on the upper and lower pressure frames, the upper and lower pressure frames, and the upper and lower sponge blocks. A hanging frame and a battery are fixed to the upper surface of the upper pressure frame. A pressure rod that can be pulled up and down is inserted at the top center of the hanging frame. A hanging plate is fixed to the bottom of the pressure rod, and an electric motor is fixed to the bottom of the hanging plate. A brush roller located directly above the perforation is fitted onto the output shaft of the electric motor. In use, one hand holds the handle on the upper pressure frame and pushes it along the guide rail, while the other hand presses down on the pressure plate to compress the spring, allowing the brush roller to move. The bottom end of the brush roller passes through the perforations in the upper pressure frame and upper sponge block, fitting snugly against the guide rail. The guide rail holes are typically located in the center of the guide rail, and the perforations are also located in the center of the pressure frame. Since the brush roller is constantly under downward pressure, when the perforation aligns with the guide rail hole, the brush roller will penetrate into the guide rail hole. At this point, the pushing device stops, and the brush roller rotates within the guide rail hole, wiping away dirt from its inner wall. After cleaning the guide rail hole, the pressure on the pressure plate is reduced, and the spring uses its own elasticity to push the pressure rod upward, pulling the brush roller out of the guide rail hole. Then, the upper pressure frame continues to move along the guide rail, while the pressure plate is pressed down. This process is repeated to clean the next guide rail hole. During the pushing device operation, the upper and lower sponge blocks wipe away dirt from the guide rail surface, allowing for a comprehensive cleaning of the guide rail surface in one go. It also allows for individual cleaning of each guide rail hole, replacing manual hand-held cleaning with mechanization, resulting in faster cleaning speeds.

[0004] While the aforementioned patents represent some improvements, they also have some shortcomings: they require two hands to operate, the brush rollers need to be manually pressed into the guide rail holes (grooves), the pushing device needs to be stopped when cleaning the guide rail holes, which reduces cleaning efficiency, and the brush rollers cannot directly clean the lubricant inside the guide rail holes that are filled with lubricant. Summary of the Invention

[0005] The purpose of this invention is to provide a machine tool track cleaning device to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a machine tool track cleaning device, comprising: a movable frame, which is movable along the length direction of the machine tool track; a cleaning scraper, which is fixedly connected to the movable frame and slidably sleeved on the machine tool track; an elastic telescopic rod, comprising a first rod body and a second rod body slidably connected to each other, the first rod body being slidably connected to the movable frame via a rotatably connected slider; an elastic element, the elastic force of which acts on the slider along the direction of travel of the movable frame; an auger, which is fixedly connected to the second rod body; and a ring, which is connected to the movable frame via a connecting... The connecting piece is elastically slidably connected to the bottom of the auger shaft; the rack is fixedly connected to the moving frame along the length of the machine tool track; the gear is coaxially fixedly connected to the first rod body, and the gear meshes with the rack; the guide plate is fixedly connected to the moving frame, and the guide plate is provided with a closed-loop guide groove, which includes a first inclined groove, a vertical groove and a second inclined groove connected end to end in sequence, and a lever that closes the second inclined groove is elastically hinged at the junction of the first inclined groove and the second inclined groove; the slide rod is rotatably connected to the second rod body through a connecting rod, and the slide rod slides with the guide groove.

[0007] Furthermore, a tension spring is fitted on the first rod and the second rod, with one end of the tension spring fixedly connected to the first rod and the other end fixedly connected to the second rod. The process of the tension spring restoring its deformation drives the elastic telescopic rod to contract.

[0008] Furthermore, the connecting component includes a sliding column and multiple spokes. The sliding column is vertically slidably connected in the slide rail of the auger shaft. One end of each spoke is fixedly connected to the sliding column, and the other end is fixedly connected to the ring. The auger shaft is provided with a relief groove to avoid the spokes. A compression spring is provided between the top of the sliding column and the slide rail, and the elastic force of the compression spring acts downward on the sliding column.

[0009] Furthermore, the first inclined groove gradually rises along the traveling direction of the moving frame, while the second inclined groove gradually decreases along the traveling direction of the moving frame.

[0010] Furthermore, one end of the lever is hinged to the guide plate, and a torsion spring is sleeved on the hinge shaft between the lever and the guide plate. One end of the torsion spring is fixedly connected to the guide plate, and the other end is fixedly connected to the lever. The other end of the lever extends in the direction of travel of the moving frame and abuts against the upper wall of the second inclined groove under the elastic force of the torsion spring.

[0011] Furthermore, the slide rod and the connecting rod are rotatably connected, and the slide rod is in rolling engagement with the guide groove.

[0012] In the above technical solution, compared with the prior art, the machine tool track cleaning device provided by the present invention can be operated with one hand. During the process of pushing the moving frame to scrape the dirt off the surface of the machine tool track by the cleaning scraper, when the auger is aligned with the slot on the machine tool track, it can automatically rotate into the slot and bring out the lubricant in the slot, which greatly improves the convenience of operation. Moreover, the cleaning scraper can continue to advance while the auger is entering the slot, without pausing and waiting, which significantly improves the cleaning efficiency.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-13 The present invention provides a machine tool track cleaning device, including a movable frame 1, a cleaning scraper 2, an elastic telescopic rod 3, an elastic element 5, an auger 6, a ring 7, a rack 9, a gear 10, a guide plate 11, and a slide rod 13.

[0031] The movable frame 1 is arranged to move along the length of the machine tool track. The power for the movable frame 1 to move along the length of the machine tool track can be provided manually or by a device that outputs linear motion in the prior art, and no specific limitation is made here.

[0032] The cleaning scraper 2 and the moving frame 1 are fixedly connected by a connecting rod 14. Therefore, the moving frame 1 can drive the cleaning scraper 2 to move synchronously. The cleaning scraper 2 is slidably sleeved on the machine tool track. That is, the cleaning scraper 2 covers the outer surface of the machine tool track in the direction of the cross section of the machine tool track (except for the part embedded in the base of the machine tool). The cleaning scraper 2 and the surface of the machine tool track are closely and dynamically attached.

[0033] The elastic telescopic rod 3 includes a first rod body 3.1 and a second rod body 3.2 that are slidably connected. The relative sliding direction between the first rod body 3.1 and the second rod body 3.2 is the axial direction of the slot on the machine tool track (i.e., the vertical direction in this embodiment). A limiting structure is provided between the first rod body 3.1 and the second rod body 3.2 to restrict the second rod body 3.2 from sliding away from the first rod body 3.1. Preferably, the first rod body 3.1 is a hollow sleeve rod with a limiting groove with an end seal opened along its length. The second rod body 3.2 is an inner rod that is slidably sleeved inside the first rod body 3.1. A protrusion located in the limiting groove is provided at the top of the inner rod. The first rod body 3.1 is slidably connected to the moving frame 1 through a rotatably connected slider 4. Specifically, the slider 4 is rotatably connected to the top of the first rod body 3.1, and the slider 4 is slidably disposed on the moving frame 1 along the traveling direction of the moving frame 1 (i.e., the length direction of the machine tool track).

[0034] The elastic telescopic rod 3 also includes a tension spring 3.3, which is sleeved on the first rod body 3.1 and the second rod body 3.2. The upper end of the tension spring 3.3 is fixedly connected to the first rod body 3.1, and the lower end is fixedly connected to the second rod body 3.2. The process of the tension spring 3.3 restoring its deformation drives the elastic telescopic rod 3 to contract, that is, drives the second rod body 3.2 to move upward relative to the first rod body 3.1.

[0035] The elastic element 5 is disposed between the movable frame 1 and the slider 4, and the elastic force of the elastic element 5 is along the direction of travel of the movable frame 1 (see attached diagram). Figure 3 The arrows in the figures (from right to left in each of the attached figures) act on the slider 4. Preferably, the elastic element 5 is a compression spring. The front end of the compression spring (relative to the traveling direction of the moving frame 1) is connected to the slider 4, and the rear end is fixedly connected to the moving frame 1. To prevent the compression spring from twisting and deforming in the non-extension direction, a telescopic rod is provided between the slider 4 and the moving frame 1. The compression spring is sleeved on the telescopic rod, and the telescopic rod can maintain the posture of the compression spring during the compression process. Alternatively, the elastic element 5 is preferably a tension spring. The rear end of the tension spring is connected to the slider 4, and the front end is connected to the moving frame 1.

[0036] The auger 6 is fixedly connected to the second rod 3.2. The axis of the auger 6 is parallel to the axial direction of the slot on the machine tool track. The diameter of the circle formed by the projection of the outer circumference of the auger 6 along its axial direction is adapted to the diameter of the slot, so that the auger 6 can fit against the inner wall of the slot and enter and exit the slot. The length of the auger 6 is not less than the depth of the slot filled with lubricant.

[0037] The ring 7 is elastically slidably connected to the bottom of the shaft of the auger 6 via the connecting member 8. The direction of elastic sliding of the ring 7 relative to the auger 6 is along the axial direction of the shaft of the auger 6. The wall thickness of the ring 7 is relatively thin, and the outer diameter of the ring 7 is adapted to the diameter of the slot, so that the outer wall of the ring 7 can fit against the inner wall of the slot and enter and exit the slot. The ring 7 is preferably made of hard plastic resin, that is, when the ring 7 is pressed and slid relative to the surface of the machine tool track, the ring 7 is a vulnerable part relative to the machine tool track to protect the machine tool track. The connecting member 8 includes a sliding column 8.1 and multiple spokes 8.2. The bottom of the shaft of the auger 6 has a slide rail opened along the axial direction, and the sliding column 8.1 slides vertically. The slide rail is dynamically connected to the shaft of the auger 6. The bottom of the slide rail is provided with a limit part to prevent the slide column 8.1 from completely disengaging from the slide rail when sliding downward relative to the shaft of the auger 6. One end of each spoke 8.2 is fixedly connected to the slide column 8.1, and the other end is fixedly connected to the ring 7, so that the ring 7 and the slide column 8.1 become a whole. The spokes 8.2 are preferably hard fine steel wires. The shaft of the auger 6 is provided with grooves to avoid the spokes 8.2. When the slide column 8.1 slides in the slide rail, the spokes 8.2 can move in the grooves. A compression spring 8.3 is provided between the slide column 8.1 and the top of the slide rail. The elastic force of the compression spring 8.3 acts downward on the slide column 8.1.

[0038] Rack 9 is fixedly connected to the movable frame 1, and the length direction of rack 9 is consistent with the length direction of the machine tool track. Gear 10 is coaxially fixedly connected to the first rod 3.1. Theoretically, gear 10 can also be coaxially fixedly connected to the second rod 3.2 or the shaft of auger 6, but for ease of assembly, in this embodiment gear 10 is fixedly connected to the first rod 3.1. Gear 10 meshes with rack 9, so that gear 10 rotates the housing, driving the elastic telescopic rod 3, auger 6 and ring 7 to rotate synchronously.

[0039] The guide plate 11 is fixedly connected to the movable frame 1. A closed-loop guide groove is provided on one vertical side of the guide plate 11. The guide groove includes a first inclined groove 11.1, a vertical groove 11.2 and a second inclined groove 11.3 connected end to end in sequence. The first inclined groove 11.1 is located below the second inclined groove 11.3. The first inclined groove 11.1 gradually rises along the traveling direction of the movable frame 1, and the second inclined groove 11.3 gradually decreases along the traveling direction of the movable frame 1. The lower inclined end of the first inclined groove 11.1 is connected to the lower end of the vertical groove 11.2, the upper end of the vertical groove 11.2 is connected to the upper inclined end of the second inclined groove 11.3, and the lower inclined end of the second inclined groove 11.3 is connected to the upper inclined end of the first inclined groove 11.1.

[0040] At the junction of the first inclined groove 11.1 and the second inclined groove 11.3, a lever 12 is elastically hinged to close the second inclined groove 11.3. Specifically, one end of the lever 12 is hinged to the guide plate 11, and a torsion spring (not shown in the figure) is sleeved on the hinge shaft between the lever 12 and the guide plate 11. One end of the torsion spring is fixedly connected to the guide plate 11, and the other end is fixedly connected to the lever 12. The other end of the lever 12 extends in the direction of travel of the moving frame 1 and abuts against the upper groove wall of the second inclined groove 11.3 under the elastic force of the torsion spring.

[0041] The slide rod 13 is rotatably connected to the second rod body 3.2 via the connecting rod 15. Specifically, one end of the connecting rod 15 is connected to the slide rod 13, and the other end is rotatably connected to the shaft of the second rod body 3.2 or the auger 6, so that the auger 6 can rotate relative to the connecting rod 15. One end of the slide rod 13 extends into the guide groove and can move along the guide groove. Preferably, the slide rod 13 is fixedly connected to the connecting rod 15, and the slide rod 13 slides in the guide groove. Alternatively, another preferred configuration is that the slide rod 13 is rotatably connected to the connecting rod 15, and the slide rod 13 rolls in the guide groove, which can reduce the friction and wear between the slide rod 13 and the guide groove.

[0042] In the above technical solution, the machine tool track cleaning device provided by the present invention can be operated with one hand. During the process of pushing the moving frame 1 to scrape the dirt off the surface of the machine tool track by the cleaning scraper 2, when the auger 6 is aligned with the slot on the machine tool track, it can automatically rotate into the slot and bring out the lubricant in the slot, which greatly improves the convenience of operation. Moreover, the cleaning scraper 2 can continue to advance while the auger 6 is entering the slot, without pausing and waiting, which significantly improves the cleaning efficiency.

[0043] When using this invention to clean machine tool tracks: First, the cleaning scraper 2 is fitted onto the machine tool track, or the cleaning scraper 2 is always fitted onto the machine tool track and placed on the redundant allowance at one end of the machine tool track for standby. The auger 6 is located in front of the cleaning scraper 2. At this time, the slide rod 13 is located at the junction of the first inclined groove 11.1 and the second inclined groove 11.3. The auger 6 and the ring 7 are not aligned with the slots, and the compression spring 8.3 is in a compressed state. The elastic force of the compression spring 8.3 causes the ring 7 to press against the upper surface of the machine tool track. (See reference...) Figure 12-13 .

[0044] Then, the moving frame 1 is driven to move along the machine tool track. The moving frame 1 drives the guide plate 11, rack 9, and cleaning scraper 2 to move synchronously. At the same time, because the elastic force of the elastic element 5 on the slider 4 is greater than the friction between the ring 7 and the machine tool track, the moving frame 1 drives the slider 4, elastic telescopic rod 3, gear 10, slide rod 13, auger 6, and ring 7 to move synchronously through the elastic element 5. When the ring 7 and the auger 6 are just aligned with the slot on the machine tool track, the ring 7 is no longer blocked by the upper surface of the machine tool track in the vertical direction. The elastic force of the compression spring 8.3 is released, allowing the slide column 8.1 to slide down in the slide. The ring 7 is quickly pressed into the slot. The ring 7 and the spokes 8.2 are both cut into the lubricant. (See reference...) Figure 2-5 .

[0045] At this time, the moving frame 1 continues to move along the guide plate 11, rack 9, and cleaning scraper 2. However, due to the obstruction of the ring 7 by the corresponding slot in the length direction of the machine tool track, the ring 7 can no longer move along the length direction of the machine tool track. That is, the auger 6, elastic telescopic rod 3, slider 4, gear 10, and slide bar 13 no longer move along the length direction of the machine tool track. As a result, on the one hand, the moving rack 9 meshes with the gear 10, causing the gear 10 to rotate. The gear 10 drives the elastic telescopic rod 3, auger 6, and ring 7 to rotate. At the same time, the elastic element 5 is also compressed and undergoes elastic deformation to store energy. On the other hand, the first inclined groove on the moving guide plate 11... 11.1 The sliding rod 13 moves in coordination with the sliding rod 13, sliding from the upper end of the first inclined groove 11.1 to the lower end of the first inclined groove 11.1 (the junction of the first inclined groove 11.1 and the vertical groove 11.2). The lever 12 can prevent the sliding rod 13 from sliding into the second inclined groove 11.3, that is, the lever 12 can prevent the sliding rod 13 from directly sliding into the second inclined groove 11.3, causing the second rod 3.2 to move downward relative to the first rod 3.1 (the elastic telescopic rod 3 extends). The first rod 3.1 drives the auger 6 and the ring 7 to move downward, thereby causing the auger 6 to cut the lubricant deeper into the groove. At the same time, the tension spring 3.3 is also stretched and stores energy. (See reference...) Figure 6-9 .

[0046] At this point, since the slide rod 13 is no longer restricted by the first inclined groove 11.1, the elastic force of the tension spring 3.3 is released, allowing the slide rod 13 to slide from the lower end of the vertical groove 11.2 to the upper end of the vertical groove 11.2 (the junction of the vertical groove 11.2 and the second inclined groove). This causes the second rod 3.2 to move upward relative to the first rod 3.1 (the elastic telescopic rod 3 retracts). The first rod 3.1 drives the auger 6 and the ring 7 to move upward to a position higher than the opening of the slot. The non-rotating auger 6 carries the lubricant out of the slot, thus cleaning the lubricant from the slot. (See reference...) Figure 10-11 .

[0047] At this point, since the ring 7 is no longer restricted by the slot and the slide rod 13 is no longer restricted by the vertical slot 11.2, the elastic force stored in the elastic element 5 is released, causing the slider 4, elastic telescopic rod 3, gear 10, slide rod 13, auger 6, and ring 7 to move relative to the moving frame 1 along the traveling direction of the moving frame 1. The slide rod 13 moves from the upper end of the second inclined slot 11.3 to the lower end of the second inclined slot 11.3 (the junction of the second inclined slot 11.3 and the first inclined slot 11.1). During this period, the slide bar 13 presses against the lever 12, causing the lever 12 to rotate downwards against the torsion spring force to clear the passage of the second inclined groove 11.3 so that the slide bar 13 can pass through. When the slide bar 13 passes over the lever 12 and reaches the junction of the second inclined groove 11.3 and the first inclined groove 11.1, the torsion spring force causes the lever 12 to rotate upwards and reset. At this time, the height of the second rod body 3.2, the auger 6, and the ring 7 decreases, and the ring 7 is pressed against the upper surface of the machine tool track again. (See reference...) Figure 12-13 During this process, the meshing of gear 10 and rack 9 causes gear 10, elastic telescopic rod 3, slide rod 13, auger 6 and ring 7 to rotate. Combined with the cutting of lubricant by spokes 8.2 when auger 6 cuts into the lubricant in the early stage, the lubricant blocks on auger 6 can be scattered. The cleaning scraper 2 then follows to scrape off the scattered lubricant blocks. If there are still lubricant blocks left on auger 6, when auger 6 cuts into the lubricant of the next slot, the remaining lubricant blocks will also be squeezed off.

[0048] By continuously advancing the moving frame 1, the present invention automatically repeats the above steps, thereby achieving cleaning of the surface of the machine tool track and each hole and groove.

[0049] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
