Description

Technical Field

[0001] This utility model relates to the field of bearing processing equipment technology, specifically to a through-type grinding machine for bearing rings. Background Technology

[0002] In the field of bearing ring processing, through-feed grinding machines are key equipment for achieving efficient grinding of bearing rings. However, in practical applications, there are significant technical problems in the material guidance and collection stages. The guide structures on the discharge plates of existing grinding machines used to guide the bearing rings are mostly designed with fixed specifications, which cannot be adjusted according to the height differences of the bearing rings being processed. When processing bearing rings of different specifications, the fixed guide structure causes the bearing rings to deviate and jam during movement due to excessive guide space, affecting the smoothness of material discharge. Therefore, a through-feed grinding machine for bearing rings is proposed. Utility Model Content

[0003] This utility model proposes a through-type grinding machine for bearing rings. A threaded rod connected to one side of the discharge plate is rotatably connected to a guide plate slidably disposed inside the discharge plate via a bearing. After the grinding machine body finishes grinding the bearing rings, when the operator rotates the threaded rod, the guide plate can be moved horizontally inside the discharge plate by utilizing the thread transmission principle between the threaded rod and the discharge plate, thereby changing the space between the guide plate and the inner wall of the discharge plate. For bearing rings of different heights, by adjusting the compression and expansion of the guide space, the guide structure can be precisely adapted to the bearing ring of the corresponding specification, avoiding the bearing ring from shifting or jamming when moving on the discharge plate, and ensuring the smoothness of the unloading process.

[0004] According to one aspect, at least one embodiment of the present invention provides a through-type grinding machine for bearing rings, comprising: a grinding machine body, support columns fixedly connected to both sides of the grinding machine body, a discharge plate provided inside the support columns, and a discharge bin fixedly connected to the bottom end of the discharge plate; The discharge plate has a threaded rod threadedly connected to one side, and a guide plate is provided at one end of the threaded rod. The threaded rod is rotatably connected to the guide plate through a bearing, and the guide plate is located inside the discharge plate.

[0005] For example, at least one embodiment of the present invention provides a through-type grinding machine for bearing rings, which further includes: a rotating handle fixedly connected to one end of the threaded rod, and the outer wall of the rotating handle is provided with anti-slip texture.

[0006] For example, at least one embodiment of the present invention provides a through-type grinding machine for bearing rings, which further includes: a connecting plate sleeved on the outer wall of the rotating handle, a stabilizing rod fixedly connected to one end of the connecting plate, and the stabilizing rod fixedly connected to the guide plate through the side of the discharge plate.

[0007] For example, at least one embodiment of the present invention provides a through-type grinding machine for bearing rings, which further includes: an adjustment groove is provided on one side of the support column, a moving block is slidably connected inside the adjustment groove, a moving groove is provided inside the moving block, a moving rod is movably arranged inside the moving groove, a first connecting block is fixedly connected to one end of the moving rod, and one end of the first connecting block is fixedly connected to the discharge plate.

[0008] For example, at least one embodiment of the present invention provides a through-type grinding machine for bearing rings, which further includes: a spring wound around the outside of the moving rod, one end of the spring being fixedly connected to the moving rod, and the other end of the spring being fixedly connected to the moving groove.

[0009] For example, at least one embodiment of the present invention provides a through-type grinding machine for bearing rings, which further includes: an array of mounting slots provided on the surface of the support column, a limiting rod inserted inside the mounting slot, and the other end of the limiting rod being fixedly connected to the first connecting block.

[0010] For example, at least one embodiment of the present invention provides a through-type grinding machine for bearing rings, which further includes: the mounting slot is provided with an array of arrays, and the limiting rods are arranged symmetrically on the first connecting block.

[0011] For example, at least one embodiment of the present invention provides a through-type grinding machine for bearing rings, which further includes: a sliding groove is provided on the side of the support column, a slider is movably disposed inside the sliding groove, a second connecting block is fixedly connected to the outer end of the slider, and the second connecting block is fixedly connected to the discharge plate.

[0012] The working principle and beneficial effects of this utility model are as follows: A threaded rod connected by a thread on one side of the discharge plate is rotatably connected to a guide plate that slides inside the discharge plate via a bearing. After the grinding machine body finishes grinding the bearing rings, when the operator rotates the threaded rod, the threaded rod and the discharge plate are driven to move the guide plate inside the discharge plate by utilizing the threaded transmission principle. This changes the space between the guide plate and the inner wall of the discharge plate. For bearing rings of different heights, by adjusting the compression and expansion of the guide space, the guide structure can be precisely adapted to the bearing rings of the corresponding specifications, preventing the bearing rings from shifting or jamming when moving on the discharge plate, and ensuring the smoothness of the unloading process.

[0013] When the height of the discharge plate needs to be adjusted, the operator can move the moving rod inside the moving groove away from the support column. At this time, the first connecting block, which is fixedly connected to the moving rod, will move accordingly, disengaging from the outer wall of the support column, thereby releasing the frictional fixation between the first connecting block and the support column. After the fixation between the first connecting block and the support column is released, the discharge plate can move in height under the action of the moving block sliding along the adjustment groove. The operator can adjust the discharge plate to a suitable height position according to actual needs. After the height adjustment is completed, the moving rod is moved in the opposite direction, so that the first connecting block re-contacts the outer wall of the support column, and the friction between the two fixes the first connecting block, thereby fixing the discharge plate at the adjusted height position, meeting the needs of different discharge plate height operations.

[0022] Refer to the instruction manual appendix Figure 1-4A through-type grinding machine for bearing rings includes a grinding machine body 1, with support columns 2 fixedly connected to both sides of the grinding machine body 1. A discharge plate 3 is provided inside the support columns 2, and a discharge bin 4 is fixedly connected to the bottom end of the discharge plate 3. A threaded rod 5 is threadedly connected to one side of the discharge plate 3, and a guide plate 6 is provided at one end of the threaded rod 5. The threaded rod 5 is rotatably connected to the guide plate 6 via a bearing, and the guide plate 6 is located inside the discharge plate 3. The grinding machine body 1 serves as the basic load-bearing component of the entire grinding machine, providing a working platform for the grinding operation of the bearing rings. All drive mechanisms and grinding mechanisms related to the grinding operation are integrated or installed on the grinding machine body 1 to ensure the stable operation of the grinding process. Support columns 2 are fixedly connected to both sides of the grinding machine body 1, and a discharge plate 3 is provided inside the support columns 2. The discharge bin 4 is fixedly connected to the bottom end of the discharge plate 3. When the bearing rings move to a designated position under the guidance of the discharge plate 3, they can be discharged through the discharge bin 4. The bearing rings are collected in a centralized manner to facilitate subsequent transfer and further processing, preventing them from being scattered and lost during the unloading process. A threaded rod 5 is threadedly connected to one side of the discharge plate 3. The axial direction of the threaded rod 5 is adapted to the length or width direction of the discharge plate 3, specifically determined by the movement path of the bearing rings on the discharge plate 3. A guide plate 6 is provided at one end of the threaded rod 5. The guide plate 6 has a plate-like structure and is located inside the discharge plate 3. The guide plate 6 and the discharge plate 3 are in a sliding fit, meaning the guide plate 6 can move along a specific direction inside the discharge plate 3. To drive the guide plate 6, the threaded rod 5 is rotatably connected to the guide plate 6 via a bearing. The inner ring of the bearing is fixedly connected to the threaded rod 5, and the outer ring is fixedly connected to the guide plate 6. This connection method ensures that during rotation, the threaded rod 5 only drives the guide plate 6 to translate, without causing the guide plate 6 to rotate with the threaded rod 5. After the grinding operation on the bearing rings is completed on the grinding machine body 1, the bearing rings will fall from the grinding machine body 1 onto the discharge plate 3. At this time, the bearing rings need to be guided so that they can fall stably into the discharge bin 4. Since the specifications of the processed bearing rings are different, their height dimensions also vary. The operator can rotate the threaded rod 5, and use the threaded connection transmission principle between the threaded rod 5 and the discharge plate 3 to make the threaded rod 5 move axially on the discharge plate 3, thereby driving the guide plate 6, which is connected to the threaded rod 5 through the bearing, to move synchronously inside the discharge plate 3. During the movement, the guide plate 6 will change the size of the space between itself and the inner wall of the discharge plate 3, realizing the compression and expansion of the guide space on the discharge plate 3. When the height of the processed bearing rings is relatively large... When the bearing ring is large, the guide plate 6 can be moved away from the inner wall of the discharge plate 3 by rotating the threaded rod 5, thus expanding the guiding space. When the height of the bearing ring being processed is small, the threaded rod 5 can be rotated in the opposite direction to move the guide plate 6 closer to the inner wall of the discharge plate 3, thus reducing the guiding space. Through this adjustment method, the guiding structure can be adapted to bearing ring parts of different heights. This not only ensures that the guide plate 6 provides stable guidance for the bearing ring, preventing the bearing ring from shifting or jamming when moving on the discharge plate 3, thus ensuring the smoothness of the unloading process, but also further expands the applicability of the equipment to bearing rings of different specifications. There is no need to replace the guide components with special ones for bearing rings of different specifications, reducing equipment operating costs and improving processing efficiency.

[0023] Then, a handle 7 is fixedly connected to one end of the threaded rod 5. The outer wall of the handle 7 is provided with anti-slip texture. When the operator holds the handle 7 and rotates the threaded rod 5, the anti-slip texture can increase the friction between the outer wall of the handle 7 and the operator's hand, reduce the possibility of slippage between the hand and the handle 7, and enable the operator to rotate the threaded rod 5 more effortlessly and stably. At the same time, it can also avoid slippage due to sweaty hands or a smooth outer wall of the handle 7, improve the safety and convenience of the operation process, and ensure that the adjustment operation of the guide plate 6 can be carried out smoothly.

[0024] Subsequently, a connecting plate 8 is fitted onto the outer wall of the rotating handle 7, and a stabilizing rod 9 is fixedly connected to one end of the connecting plate 8. The stabilizing rod 9 passes through the side of the discharge plate 3 and is fixedly connected to the guide plate 6. The stabilizing rod 9 and the discharge plate 3 are in a sliding fit, that is, the stabilizing rod 9 can slide smoothly in the through hole of the discharge plate 3. When the threaded rod 5 drives the guide plate 6 to move on the discharge plate 3, since the connecting plate 8 is fitted onto the rotating handle 7 and the connecting plate 8 is fixedly connected to the stabilizing rod 9, and the stabilizing rod 9 is fixedly connected to the guide plate 6, the connecting plate 8 can play the role of linking the stabilizing rod 9 and the threaded rod 5. While the threaded rod 5 drives the guide plate 6 to move, the stabilizing rod 9 will slide synchronously in the through hole of the discharge plate 3. Through the support and guidance of the stabilizing rod 9 on the guide plate 6, the movement direction of the guide plate 6 can be effectively restricted, avoiding the guide plate 6 from deviating or tilting during the movement, ensuring that the guide plate 6 always moves smoothly along the set direction, further improving the stability of the guide plate 6 in guiding the bearing ring, and ensuring the smoothness of the material dropping process.

[0025] Next, an adjustment groove 10 is provided on one side of the support column 2. A movable block 11 is slidably connected inside the adjustment groove 10. A movable groove 12 is provided inside the movable block 11. A movable rod 13 is movably installed inside the movable groove 12. One end of the movable rod 13 is fixedly connected to a first connecting block 15, and one end of the first connecting block 15 is fixedly connected to the discharge plate 3. When it is necessary to adjust the height of the discharge plate 3, the operator can move the movable rod 13 to move it away from the support column 2 inside the movable groove 12. At this time, the first connecting block 15 fixedly connected to the movable rod 13 will move accordingly, disengaging from contact with the outer wall of the support column 2. The friction fixation between the first connecting block 15 and the support column 2 is released. After the fixation between the first connecting block 15 and the support column 2 is released, the discharge plate 3 can move in the height direction under the action of the sliding block 11 along the adjustment groove 10. The operator can adjust the discharge plate 3 to a suitable height position according to actual needs. After the height adjustment is completed, the moving rod 13 is moved in the opposite direction to make the first connecting block 15 contact the outer wall of the support column 2 again, and fix the first connecting block 15 through the friction between the two, thereby fixing the discharge plate 3 at the adjusted height position to meet the needs of different height operations of the discharge plate 3.

[0026] At this time, a spring 14 is wound around the outside of the moving rod 13. One end of the spring 14 is fixedly connected to the moving rod 13, and the other end of the spring 14 is fixedly connected to the moving groove 12. When the operator moves the moving rod 13 away from the support column 2 to release the fixation of the first connecting block 15, the moving rod 13 will stretch or compress the spring 14, causing the spring 14 to store elastic potential energy. When the operator releases the moving rod 13, the spring 14 will return to its original position under the action of elastic potential energy, driving the moving rod 13 to move closer to the support column 2, thereby making the first connecting block 15 tightly contact the outer wall of the support column 2. The friction between the two achieves the fixation of the first connecting block 15. The setting of the spring 14 can automatically realize the reset and fixation of the first connecting block 15 without the operator having to manually position the moving rod 13. At the same time, it can also ensure that the friction fixation effect between the first connecting block 15 and the support column 2 remains stable, avoiding the situation where the fixation is not firm due to human negligence.

[0027] Next, an array of mounting slots 16 is provided on the surface of the support column 2, and a limiting rod 17 is inserted inside the mounting slot 16. The other end of the limiting rod 17 is fixedly connected to the first connecting block 15. To further improve the stability of the first connecting block 15 fixed on the support column 2 and to prevent displacement of the first connecting block 15 under external forces such as the impact of the bearing ring falling or equipment vibration when fixed by friction alone, thereby affecting the stability of the discharge plate 3, an array of mounting slots 16 is provided on the surface of the support column 2. The opening direction of the mounting slots 16 is perpendicular to the height direction of the support column 2, and the array of mounting slots 16 is evenly distributed along the height direction of the support column 2. When the height of the discharge plate 3 is adjusted... After the section is completed, under the reset action of the spring 14, the first connecting block 15 moves towards the support column 2. At this time, the limiting rod 17 fixed on the first connecting block 15 will be inserted into the corresponding mounting slot 16 on the surface of the support column 2. Through the cooperation of the limiting rod 17 and the mounting slot 16, the position of the first connecting block 15 can be further limited to prevent the first connecting block 15 from moving in the horizontal direction. This significantly improves the stability of the first connecting block 15 fixed on the support column 2, ensuring that the discharge plate 3 can run stably at the adjusted height position. It also prevents the discharge plate 3 from tilting or shifting due to the loosening of the first connecting block 15, which would affect the normal dropping of the bearing rings.

[0028] Secondly, the mounting slots 16 are provided with an array, and the limiting rods 17 are symmetrically arranged on the first connecting block 15. The operator can insert the limiting rods 17 into the mounting slots 16 at different height positions according to the required adjustment height, so that the discharge plate 3 can be fixed at multiple different height positions, further improving the flexibility and adaptability of the equipment height adjustment, and meeting the processing needs of more different scenarios.

[0029] Finally, a sliding groove 18 is provided on the side of the support column 2, and a slider 19 is movably disposed inside the sliding groove 18. A second connecting block 20 is fixedly connected to the outer end of the slider 19, and the second connecting block 20 is fixedly connected to the discharge plate 3. When the operator adjusts the height of the discharge plate 3, and the moving block 11 moves along the height direction of the support column 2 inside the adjustment groove 10, the movement of the discharge plate 3 will drive the slider 19 to move synchronously inside the sliding groove 18 because the second connecting block 20 fixes the slider 19 to the discharge plate 3. The groove 18, in conjunction with the sliding groove 18, further guides the movement direction of the discharge plate 3. Together with the guiding function of the moving block 11 and the adjusting groove 10, it effectively limits the movement trajectory of the discharge plate 3 during the height adjustment process, preventing the discharge plate 3 from shifting left or right or tilting forward or backward. This ensures that the discharge plate 3 always moves smoothly along the set vertical direction, further improving the stability of the height adjustment of the discharge plate 3 and ensuring the levelness of the discharge plate 3 after adjustment. This, in turn, ensures that the bearing ring can move stably on the discharge plate 3 and fall smoothly.
