[0002] Linear guides are linear guiding metal components. During the production of linear guides, all four edges at both ends of the guide need to be chamfered. Existing chamfering devices chamfer one side at a time, resulting in low production efficiency and requiring frequent repositioning of the guide, which complicates the operation process.

[0003] Therefore, it is necessary to provide a guide rail chamfering device and chamfering method. Summary of the Invention

The first cutter head and the first bevel gear are fixedly connected, and the second cutter head and the second bevel gear are fixedly connected. The first bevel gear and the second bevel gear mesh, and the first cutter head and the second cutter head chamfer the upper and lower surfaces of the slider simultaneously when it is placed.

[0008] Furthermore, the tooling mechanism includes a first platform mounted on the frame, a second platform lower than the end face of the first platform, an arc transition platform fixedly mounted at the discharge end of the first platform, a guide plate mounted on the frame to form a vertical channel with the discharge end of the first platform, and a first pushing component mounted on the frame to push the guide rail downward in the vertical channel. Both ends of the guide rail extend out from the sides of the first platform and the sides of the second platform. The two end faces of the guide rail in the vertical channel abut against the guide plate and the first platform, respectively. The angle of the arc transition platform is 90°. The arc transition platform is used to guide the guide rail to the second platform. The first grinding head is located on the side of the first platform, and the second grinding head is located on the side of the second platform.

[0009] Furthermore, the first pushing component includes a first cylinder mounted vertically on the frame and a first push plate fixedly mounted at the output end of the first cylinder.

[0010] Furthermore, the lower end of the arc transition platform and the upper surface of the second platform are provided with a reserved channel whose height is less than the height between the guide rail end face. The tooling mechanism also includes a second pushing component set on the frame. The second pushing component includes a second cylinder fixedly set on the frame and a second push plate fixedly set on the output end of the second cylinder. The second push plate pushes the guide rail on the second platform towards the second grinding head along the reserved channel.

[0011] Furthermore, the roller pressing mechanism includes a mounting frame on the machine frame, a first roller and a second roller on the mounting frame. The first roller is used to press the guide rail when grinding the end face, and the second roller is used to press the guide rail when grinding the sliding reference surface. The central axis of the first roller and the second roller is horizontal and perpendicular to the direction of movement of the guide rail.

[0012] Furthermore, the feeding mechanism includes a third pushing component, a base plate that docks with the tooling mechanism, a mounting plate on the base plate, a material box with a variable volume, and a second driving component on the mounting plate for driving the material box to change its volume.

The third pushing component is used to push the guide rails in the second channel toward the tooling mechanism.

[0013] Furthermore, the material box includes a first opening frame and a second opening frame that are horizontally slidably connected to the mounting plate. The first opening frame includes a baffle A, and baffles B and C symmetrically arranged on both sides of baffle A. Baffle B is horizontally slidably connected to the mounting plate.

The tooth grooves of the rack b correspond vertically to the tooth grooves of the rack B, and the circular gear meshes with both the rack B and the rack b simultaneously.

[0015] The guide rail chamfering method employs a guide rail chamfering device. Before grinding, a primary drive assembly drives two grinding assemblies to move in opposite directions, ensuring the distance between the two grinding assemblies is greater than the length of the guide rail. The guide rail is fed to the tooling mechanism via a feeding mechanism, positioning it between the two grinding assemblies. Then, the primary drive assembly drives the two grinding assemblies to move towards each other. While the guide rail to be ground is being rolled by a roller pressing mechanism, the grinding assemblies grind both ends of the guide rail. Finally, a collecting mechanism collects the ground guide rail.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2As shown, the guide rail chamfering device provided in the embodiment of this application includes a frame 1, a feeding mechanism 2 mounted on the frame 1, a tooling mechanism 3 mounted on the frame 1, a grinding mechanism 4 mounted on the frame 1 for grinding the guide rail on the tooling mechanism 3, a roller pressing mechanism 5 for pressing the ground guide rail, and a receiving mechanism 6. The grinding mechanism 4 includes two grinding components 41 slidably mounted on the frame 1 for grinding both ends of the guide rail, and a first drive component 42 for driving the two grinding components 41 to move relative to each other.

[0030] In actual use, before grinding, the first drive assembly 42 drives the two grinding assemblies 41 to move in opposite directions, so that the distance between the two grinding assemblies 41 is greater than the length of the guide rail. The feeding mechanism 2 feeds the guide rail to the tooling mechanism 3, so that the guide rail is located between the two grinding assemblies 41. Then, the first drive assembly 42 drives the two grinding assemblies 41 to move towards each other. Then, while the roller pressing mechanism 5 rolls the guide rail to be ground, the grinding assemblies 41 grind both ends of the guide rail. Finally, the collecting mechanism 6 collects the ground guide rail.

[0031] In the above design, by setting two grinding components 41 to grind both ends of the guide rail simultaneously, the working efficiency can be effectively improved. By setting the roller pressing mechanism 5 to press the guide rail, the stability of the guide rail during the grinding process can be effectively guaranteed, and the grinding accuracy can be guaranteed.

[0032] Specifically: such as Figure 2 and Figure 3As shown, the grinding assembly 41 includes a first frame 411 slidably connected to the frame 1, a first grinding head 412 mounted on the first frame 411 for grinding the two sliding reference surfaces of the guide rail, and a second grinding head 413 for grinding the two end faces of the guide rail. The first grinding head 412 and the second grinding head 413 have the same structure. The first grinding head 412 includes a first plate 403 mounted on the first frame 411, a first fixed seat 401 and a second fixed seat 402 mounted on the first plate 403, a first motor 404 mounted on the first plate 403, a first rotating shaft 405 rotatably mounted on the first fixed seat 401, and a second fixed seat 405 rotatably mounted on the second fixed seat 402. The second rotating shaft 406 on the seat 402, the connecting shaft 407 whose two ends are fixedly connected to the first rotating shaft 405 and the output shaft of the first motor 404 respectively, the first cutter head 408 and the first bevel gear 409 fixedly connected to the first rotating shaft 405 coaxially, and the second cutter head 410 and the second bevel gear 400 fixedly connected to the second rotating shaft 406 coaxially. The first cutter head 408 and the first bevel gear 409 are fixedly connected, and the second cutter head 410 and the second bevel gear 400 are fixedly connected. The first bevel gear 409 and the second bevel gear 400 mesh. The first cutter head 408 and the second cutter head 410 chamfer the upper and lower surfaces of the slider simultaneously when it is placed.

[0033] It should be noted that the first drive component 42 is a left- or right-hand screw, and the left- or right-hand screw is provided with two nuts that are respectively connected to the two grinding components 41.

[0034] In actual use, the guide rail ends are moved by the first frame 411 under the drive of the first drive assembly 42, the two sliding reference surfaces of the guide rail are ground by the first grinding head 412, and then the two end faces of the guide rail are ground by the second grinding head 413. The working principle of grinding head 412 and grinding head 413 is the same. The working principle of grinding head 412 is as follows: the connecting shaft 407 is driven to rotate by motor 404, so that the rotating shaft 405 rotates synchronously, realizing the synchronous rotation of cutting head 408 and bevel gear 409. Thus, cutting head 408 grinds the sliding reference surface on the guide rail. During the rotation of bevel gear 409, since bevel gear 409 meshes with bevel gear 400 and bevel gear 400 is fixedly connected to cutting head 410, bevel gear 400 rotates synchronously with bevel gear 409, and cutting head 410 rotates synchronously with cutting head 408. Thus, cutting head 408 and cutting head 410 grind the opposite sides of the guide rail end at the same time.

[0035] In the above design, the structural design and specific implementation of the first grinding head 412 and the second grinding head 413 can simultaneously perform chamfering grinding on both sides of the guide rail end, ensuring the grinding accuracy and stability of both sides.

[0036] Specifically: such as Figure 2 and Figure 4 As shown, the tooling mechanism 3 includes a first platform 31 mounted on the frame 1, a second platform 32 lower than the end face of the first platform 31, an arc transition platform 33 fixedly mounted at the discharge end of the first platform 31, a guide plate 34 mounted on the frame 1 to form a vertical channel with the discharge end of the first platform 31, and a first pushing component 35 mounted on the frame 1 to push the guide rail downward in the vertical channel. Both ends of the guide rail extend from the sides of the first platform 31 and the sides of the second platform 32. The angle of the arc transition platform 33 is 90°. The two end faces of the guide rail in the vertical channel abut against the guide plate 34 and the first platform 31, respectively. The arc transition platform 33 guides the guide rail onto the second platform 32. A first grinding head 412 is located on the side of the first platform 31, and a second grinding head 413 is located on the side of the second platform 32.

[0037] In actual use, one end face of the guide rail contacts the first platform 31, so that the guide rail end face is chamfered on the first platform 31 using the first grinding head 412. Then, through the continuous feeding of the feeding mechanism, the guide rail after grinding is pushed forward into the vertical channel by the subsequent guide rail to be ground. Then, it is pushed downward by the first pushing component 35, and the guide rail slides along the arc surface of the arc transition platform 33 to the second platform 32. At this time, one end face of the guide rail contacts the second platform 32, and then the end face of the guide rail is chamfered by the second grinding head 413.

[0038] In the above design, the structural design and specific implementation of the tooling mechanism 3 can quickly change the placement state of the guide rail by 90°, so that after the first grinding head 412 chamfers, the second grinding head 413 can chamfer the other two surfaces of the guide rail.

[0039] Specifically: such as Figure 4 As shown, the first pushing component 35 includes a first cylinder 351 vertically mounted on the frame 1 and a first push plate 352 fixedly mounted on the output end of the first cylinder 351.

[0040] In actual use, the first push plate 352 is pushed down by the first cylinder 351, so that the guide rail slides down from the vertical channel to the arc transition platform 33.

[0041] In the above design, the structural design and specific implementation of the first pushing component 35 can effectively move the guide rail from the vertical channel to the arc transition platform 33.

[0042] Specifically: such as Figure 4 As shown, the lower end of the arc transition platform 33 and the upper end face of the second platform 32 are provided with a reserved channel whose height is less than the height between the guide rail end faces. The tooling mechanism 3 also includes a second pushing component 36 set on the frame 1. The second pushing component 36 includes a second cylinder 361 fixedly set on the frame 1 and a second push plate 362 fixedly set on the output end of the second cylinder 361. The second push plate 362 pushes the guide rail on the second platform 32 towards the second grinding head 413 along the reserved channel.

[0043] In actual use, after the guide rail slides from the arc transition platform 33 to the second platform 32, there is still a distance between it and the second grinding head 413. At this time, the second cylinder 361 drives the second push plate 362 to move horizontally towards the second grinding head 413, pushing the guide rail to the grinding position of the second grinding head 413.

[0044] In the above design, the structural design and specific implementation of the tooling mechanism 3 can effectively enable the guide rail to move precisely to the grinding position.

[0045] Specifically: such as Figure 1 and Figure 4 As shown, the rolling mechanism 5 includes a mounting frame 51 mounted on the frame 1, a first roller 52 and a second roller 53 mounted on the mounting frame 51. The first roller 52 is used to roll the guide rail when grinding the end face, and the second roller 53 is used to roll the guide rail when grinding the sliding reference surface. The central axis of the first roller 52 and the second roller 53 is horizontal and perpendicular to the direction of movement of the guide rail.

[0046] In actual use, the guide rail in the grinding state of the first grinding head 412 is rolled by the first roller shaft 52, and the guide rail in the grinding state of the second grinding head 413 is rolled by the second roller shaft. When the guide rail moves, the first roller shaft 52 or the second roller shaft 53 rolls because the guide rail is tangent to the first roller shaft 52 or the second roller shaft 53.

[0047] In the above design, the roller pressing mechanism 5 can effectively fix the guide rail in the chamfered state, reduce vibration during the guide rail grinding process, and improve the grinding accuracy.

[0048] Specifically: such as Figure 1 , Figure 4As shown, the feeding mechanism 2 includes a third pushing component 21, a base plate 22 that docks with the tooling mechanism 3, a mounting plate 23 disposed on the base plate 22, a material box 24 with a variable housing volume, and a second driving component 25 disposed on the mounting plate 23 for driving the material box 24 to change its housing volume. The material box 24 has a hollow structure, and a second channel 201 is provided between the lower end of the material box 24 and the base plate 22 for only one row of guide rails to pass through. The third pushing component 21 is used to push the guide rails in the second channel 201 toward the tooling mechanism 3.

[0049] In actual use, the material box 24 is driven by the second drive component 25 to change to a receiving volume that matches the guide rail. Then, the guide rails to be chamfered are stacked in the material box 24. The bottom layer of guide rails automatically falls into the second channel 201. The guide rails are driven by the third push component 21 to move from the second channel 201 to the tooling mechanism 3 until the guide rails move onto the tooling mechanism 3.

[0050] In the above design, the structural design and specific implementation of the feeding mechanism can effectively realize automatic feeding of guide rails of different lengths, effectively improving the compatibility of the feeding mechanism and the convenience of feeding.

[0051] Specifically: such as Figure 4 , Figure 5 and Figure 6 As shown, the material box 24 includes a first opening frame and a second opening frame that are horizontally slidably connected to the mounting plate 23. The first opening frame includes a baffle A241 and baffles B242 and C243 symmetrically arranged on both sides of baffle A241. Baffle B242 is horizontally slidably connected to the mounting plate 23. The second opening frame includes a baffle a244 and baffles b245 and c246 symmetrically arranged on both sides of baffle a244. Baffle A241 is symmetrical to baffle a244. Baffle b245 is slidably connected to the mounting plate 23. Baffle b245 is slidably connected to the upper end of baffle B242. Baffle c246 is slidably connected to the upper end of baffle C243. The sum of the heights of baffle b245 and baffle B242 is equal to the height of baffle A241.

[0052] In actual use, when the material box 24 needs to be adjusted to a suitable length for the guide rail, the second drive assembly 25 drives the first and second opening frames to move relative to each other, thereby adjusting the distance between baffle A241 and baffle a244 to match the length of the guide rail. Baffles b245, baffle B242, baffle c246, and baffle C243 limit the movement of the sides of the guide rail.

[0053] In the above design, the structural design and specific implementation of the material box 24 facilitate quick adjustment of the size of the material box 24.

[0054] Specifically: such as Figure 4 As shown, the second drive assembly 25 includes a rack B251 horizontally mounted on baffle B242, a rack b252 horizontally mounted on baffle b245, a second motor 253 mounted on mounting plate 23, and a circular gear 254 mounted on the output end of the second motor 253. The tooth grooves of the rack b252 correspond vertically to the tooth grooves of the rack B251, and the circular gear 254 meshes with both the rack B251 and the rack b252.

[0055] In actual use, the circular gear 254 is driven to rotate by the second motor 253. Since the circular gear 254 meshes with the racks b252 and b251 simultaneously, the baffles B242 and b245 move relative to each other. Since the baffles B242 are fixedly connected to the baffles A241 and the baffles b245 are fixedly connected to the baffles a244, the baffles a244 and A241 move relative to each other, so that the distance between the baffles a244 and A241 is adapted to the length of the guide rail.

[0056] In the above design, the structural design and specific implementation of the second drive component 25 can effectively realize the relative driving of the first opening frame and the second opening frame.

[0057] The guide rail chamfering method employs a guide rail chamfering device. Before grinding, the first drive assembly 42 drives two grinding assemblies 41 to move in opposite directions, ensuring the distance between the two grinding assemblies 41 is greater than the length of the guide rail. The guide rail is fed to the tooling mechanism 3 via the feeding mechanism 2, positioning it between the two grinding assemblies 41. Subsequently, the first drive assembly 42 drives the two grinding assemblies 41 to move towards each other. Then, while the roller pressing mechanism 5 rolls the guide rail to be ground, the grinding assemblies 41 grind both ends of the guide rail. Finally, the collecting mechanism 6 collects the ground guide rail.

[0058] In further detail, it should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
