Description

Technical Field

[0001] This invention belongs to the field of cage processing, specifically a device and method for processing large copper cage pockets. Background Technology

[0002] Large brass cages are key components in extra-large bearings, primarily providing precise support and separation between the rolling elements. These cages are typically cast from high-strength brass to withstand harsh operating conditions such as heavy loads and high speeds. One of the core manufacturing challenges lies in the machining of the pockets. The "pocket"-shaped recesses where each rolling element is located are called pockets, and their dimensional accuracy and surface finish directly determine the bearing's operational smoothness and lifespan. During machining, the cast blank must be precision milled or drilled and bored to ensure that the pockets are evenly distributed, uniformly shaped, and optimally fitted with the rolling elements. This is the final crucial step in ensuring the overall performance of the bearing.

[0003] When machining the pockets of large bearing cages, the workpiece needs to be moved to a specific position and then clamped and fixed by a fixture. However, the cage is heavy, so it is inconvenient to move and adjust it during the clamping and fixing process. This may cause wear and deformation of the cage during movement. Summary of the Invention

[0004] This invention provides a large copper cage pocket processing device and method, which solves the technical problem in the related art that when processing pockets on large bearing cages, the workpiece needs to be moved to a specific position and then clamped and fixed by a fixture. However, the cage is heavy, so it is inconvenient to move and adjust it during the clamping and fixing process, and the movement may cause wear and deformation of the cage.

[0005] The first aspect of this invention discloses a large copper cage pocket processing device, comprising a base, a placement platform fixedly mounted on the base, a limit adjustment device disposed inside the placement platform, a first cage placed on the limit adjustment device, a first support slider slidably mounted inside the base, symmetrically arranged first fixing blocks fixedly mounted on the side of the first support slider, a first screw rotatably mounted inside the first fixing block, a second support slider disposed outside the first screw, a first telescopic rod fixedly mounted on the side of the second support slider, a third support block fixedly mounted at the end of the first telescopic rod, and a cutting tool fixedly mounted on the lower part of the third support block. The limiting adjustment device is used to move and clamp the first retainer. The limiting adjustment device includes a clamping member, a support member, a first fixing plate, and a limiting member. The clamping member is provided inside the placement platform. The first fixing plate is fixedly installed at the center of the base. The support member is slidably installed on the first fixing plate. The limiting member is provided at the upper part of the first fixing plate. The support member descends, causing the first retainer to descend. The clamping member rotates to clamp the first retainer. The support member is used to adjust the position and height of the first retainer to facilitate clamping by the clamping member. The limiting member is used to lock the position of the support member to prevent displacement of the first retainer during processing.

[0006] As a further optimization of the present invention, the clamping member includes a first rack slidably mounted in a circumferential array inside the placement platform, teeth fixedly mounted on the side of the first rack, a first internal gear ring rotatably mounted inside the placement platform, the first internal gear ring being located below the first rack, a first gear rotatably mounted in a circumferential array inside the placement platform, a second gear fixedly mounted on the bottom of the first gear, the first gear meshing with the teeth, and the second gear meshing with the first internal gear ring.

[0007] As a further optimization of the present invention, the support member includes a second threaded rod rotatably mounted inside a first fixed plate, a second slider disposed outside the second threaded rod, a first threaded rod rotatably mounted inside the second slider, a third slider disposed outside the first threaded rod, a first slider fixedly mounted on the top of the third slider, a second telescopic rod fixedly mounted on the top of the first slider, a second spring disposed on the second telescopic rod, a first placement circular plate fixedly mounted on the top of the second telescopic rod, and a first retainer placed on the first placement circular plate.

[0008] As a further optimization of the present invention, the limiting component includes a limiting slide rod fixedly installed in a circumferential array on the top of the first fixed plate. A first spring is provided on the outside of the limiting slide rod. A second locking rack is slidably installed on the upper part of the limiting slide rod. A first locking rod is fixedly installed on the side of the second locking rack. A locking compression block is fixedly installed on the bottom of the first locking rod. A third gear is fixedly installed on the outside of the second threaded rod. A fourth gear is fixedly installed on the end of the first threaded rod. The locking compression block is used to limit the third gear, and the second locking rack is used to limit the fourth gear.

[0009] As a further optimization of the present invention, a power component is fixedly installed at the bottom of the second gear located above the second locking rack. The rotation of the power component causes the clamping component to retract, and the descent of the power component causes the limiting component to descend.

[0010] As a further optimization of the present invention, the power component includes a first protrusion fixedly installed at the bottom of the second gear, a power slide rod movably installed inside the first protrusion, a second protrusion fixedly installed outside the power slide rod, a third protrusion symmetrically installed on the outer wall of the power slide rod, a fifth gear slidably installed outside the power slide rod, a power limiting block rotatably installed at the bottom of the power slide rod, a power limiting rod fixedly installed outside the power limiting block, and the power limiting rod slidably installed inside the first fixed plate.

[0011] As a further optimization of the present invention, the second locking rack is symmetrically arranged with respect to the first fixing plate, and the first locking rod is symmetrically arranged with respect to the first fixing plate.

[0012] As a further optimization of the present invention, the distance between the two second locking racks is greater than the length of the second slider.

[0013] As a further optimization of the present invention, the outer diameter of the first retainer is smaller than the diameter of the top of the first placement circular plate.

[0014] The second aspect of this invention discloses a method for machining pockets in a large copper cage, comprising the following steps: Step 1: First, use the hoisting mechanism to move the first retainer above the first placement circular plate. Then, start the second telescopic rod to lower the first placement circular plate and the first retainer. At this time, the limiting member does not lock the support member. Then, start the motor to drive the fifth gear to rotate, in preparation for clamping the first retainer. Step 2: The rotation of the fifth gear drives the rotation of the second gear, which in turn drives the rotation of the first internal gear ring. The rotation of the first internal gear ring can drive the rotation of multiple first gears and second gears, thereby causing the first rack to slide inside the placement platform to clamp the first cage until the clamping is completed, and then the fifth gear continues to rotate. Step 3: The first protrusion stops rotating, and the second protrusion rotates out of the notch on the first protrusion, lifting the power slide bar, which drives the power limiting block and the power limiting rod to descend, squeezing the first locking rod and the second locking rack, so that the position of the first placement round plate is locked, thus completing the clamping and locking work. After that, the cutting tool can be started to process the first cage.

[0015] The beneficial effects of this invention are as follows: The present invention discloses a large copper cage pocket processing device and method. By adjusting the height of the first cage and positioning it at the center of the placement table through a support member, the large cage can be easily moved and clamped, improving the ease of movement of the first cage and addressing the problem of the first cage being difficult to clamp. Furthermore, the first fixed plate is provided with a limiting member to limit the adjustment of the support member, preventing displacement of the support member during processing and improving the stability of the first cage during tool processing.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] like Figures 1 to 3 As shown in the figure, a large copper cage pocket processing device according to an embodiment of the present invention includes a base 1, a placement platform 11 fixedly installed on the base 1, a limit adjustment device 2 provided inside the placement platform 11, a first cage 12 placed on the limit adjustment device 2, a first support slider 13 slidably installed inside the base 1, a first fixing block 14 symmetrically arranged fixedly installed on the side of the first support slider 13, a first screw 15 rotatably installed inside the first fixing block 14, a second support slider 16 provided outside the first screw 15, a first telescopic rod 17 fixedly installed on the side of the second support slider 16, a third support block 18 fixedly installed at the end of the first telescopic rod 17, and a cutting tool 19 fixedly installed at the lower part of the third support block 18. The limit adjustment device 2 is used to move and clamp the first cage 12. like Figures 3 to 4As shown, the limiting adjustment device 2 includes a clamping member 21, a support member 22, a first fixing plate 23, and a limiting member 24. The clamping member 21 is provided inside the placement platform 11. The first fixing plate 23 is fixedly installed at the center of the base 1. The support member 22 is slidably installed on the first fixing plate 23. The limiting member 24 is provided on the upper part of the first fixing plate 23. The support member 22 descends, causing the first retainer 12 to descend. The clamping member 21 rotates to clamp the first retainer 12. The support member 22 is used to adjust the position and height of the first retainer 12 to facilitate clamping by the clamping member 21. The limiting member 24 is used to lock the position of the support member 22 to prevent displacement of the first retainer 12 during processing.

[0020] It should be noted that due to the large size and weight of the first retainer 12, problems such as difficulty in movement and friction always occur when using a clamp. Therefore, a support member 22 is provided on the top of the first fixing plate 23, and a clamping member 21 is provided inside the placement table 11. When the first retainer 12 is placed on the support member 22, the position of the first retainer 12 needs to be fixed and clamped. However, the position of the first retainer 12 may not be exactly centered on the support member 22. At this time, the support member 22 can be lowered to a certain height, so that the processing position of the first retainer 12 is above the placement table 11, which will not obstruct the tool 19 from processing the first retainer 12. Then, the clamping member 21 can be rotated to clamp the first retainer 12, and the top of the support member 22 is lowered into the placement table 11, so that the first retainer 12 has a certain amount of movement space, thereby facilitating the movement and clamping of the first retainer 12 until the first retainer 12 is fully moved. When the holder 12 is moved to a position directly above the placement table 11, the limiting member 24 can be activated to limit the position of the support member 22, preventing the support member 22 from shifting when the tool 19 processes the first holder 12. This solves the problem that the first holder 12 is not easy to move after being placed on the fixture. At the same time, it allows the first holder 12 to be adjusted to the center position of the placement table 11, making it easier for the tool 19 to process the first holder 12. This device adjusts the height of the first holder 12 and positions it at the center of the placement table 11 through the support member 22, making it easier to move and clamp large holders, improving the ease of movement of the first holder 12 and solving the problem of the first holder 12 being difficult to clamp. The limiting member 24 on the first fixed plate 23 can limit the position of the adjusted support member 22, preventing the support member 22 from shifting during processing and improving the stability of the first holder 12 when the tool 19 processes it.

[0021] like Figures 4 to 5As shown, the clamping member 21 includes a first rack 212 slidably mounted in a circumferential array inside the placement platform 11. Teeth 213 are fixedly mounted on the side of the first rack 212. A first internal gear ring 211 is rotatably mounted inside the placement platform 11, and the first internal gear ring 211 is located below the first rack 212. A first gear 214 is rotatably mounted in a circumferential array inside the placement platform 11. A second gear 215 is fixedly mounted on the bottom of the first gear 214. The first gear 214 meshes with the teeth 213, and the second gear 215 meshes with the first internal gear ring 211.

[0022] It should be noted that when the first retainer 12 descends, a motor can drive one of the first gears 214 to rotate, thereby driving multiple first racks 212 to move closer to the center of the first retainer 12, thus facilitating the clamping effect of the first retainer 12. During the clamping process, the first retainer 12 can automatically adjust its position on the support 22 so that the first retainer 12 is located at the exact center of the placement table 11, which facilitates the processing of the first retainer 12.

[0023] like Figures 5 to 6 As shown, the support member 22 includes a second threaded rod 228 rotatably mounted inside the first fixed plate 23, a second slider 225 disposed outside the second threaded rod 228, a first threaded rod 227 rotatably mounted inside the second slider 225, a third slider 226 disposed outside the first threaded rod 227, a first slider 224 fixedly mounted on the top of the third slider 226, a second telescopic rod 222 fixedly mounted on the top of the first slider 224, a second spring 223 disposed on the second telescopic rod 222, a first placement circular plate 221 fixedly mounted on the top of the second telescopic rod 222, and the first retainer 12 placed on the first placement circular plate 221.

[0024] It should be noted that when the second telescopic rod 222 is retracted, the first placement circular plate 221 drives the first retainer 12 to descend. The bottom of the processing position of the first retainer 12 is always above the placement table 11. The distance the first retainer 12 descends does not affect the processing effect of the tool 19 on the first retainer 12. The first placement circular plate 221 moves into the placement table 11. The bottom of the second telescopic rod 222 is provided with a first slider 224 and a second slider 225. Therefore, the first internal toothed ring 211 can move at any angle inside the placement table 11, which facilitates the clamping member 21 to clamp and move the first retainer 12, so that the first retainer 12 is located in the exact center of the placement table 11. This solves the problem that the large first retainer 12 is not easy to move and clamp, and improves the processing accuracy of the first retainer 12.

[0025] like Figures 5 to 7 As shown, the limiting member 24 includes a limiting slide rod 241 fixedly installed in a circumferential array on the top of the first fixed plate 23. A first spring 242 is provided on the outside of the limiting slide rod 241. A second locking rack 245 is slidably installed on the upper part of the limiting slide rod 241. A first locking rod 243 is fixedly installed on the side of the second locking rack 245. A locking compression block 244 is fixedly installed on the bottom of the first locking rod 243. A third gear 246 is fixedly installed on the outside of the second threaded rod 228. A fourth gear 247 is fixedly installed on the end of the first threaded rod 227. The locking compression block 244 is used to limit the third gear 246, and the second locking rack 245 is used to limit the fourth gear 247.

[0026] It should be noted that after the position and height of the first placement plate 221 are determined, the position of the support member 22 needs to be locked. This can be achieved by using a telescopic rod to drive the second locking rack 245, the first locking rod 243, and the locking pressing block 244 to descend, thereby causing the second locking rack 245 to mesh with the fourth gear 247, and the locking pressing block 244 to mesh with the third gear 246. This limits the second threaded rod 228 and the first threaded rod 227, thus limiting the position of the first placement plate 221 and preventing displacement of the first placement plate 221 during processing, thereby improving the processing stability of the first cage 12.

[0027] like Figures 4 to 6 As shown, a power component 25 is fixedly installed at the bottom of the second gear 215 located above the second locking rack 245. The rotation of the power component 25 causes the clamping component 21 to retract, and the descent of the power component 25 causes the limiting component 24 to descend.

[0028] It should be noted that, in order to facilitate the retraction of the clamping member 21 and the descent of the limiting member 24, a power member 25 is fixedly installed at the bottom of the second gear 215. When the power member 25 rotates, it can drive the clamping member 21 to retract, thereby clamping the first retainer 12. After clamping is completed, it can descend, thereby driving the limiting member 24 to descend and completing the limiting function of the support member 22.

[0029] like Figures 6 to 7As shown, the power component 25 includes a first protrusion 251 fixedly installed at the bottom of the second gear 215, a power slide rod 252 movably installed inside the first protrusion 251, a second protrusion 253 fixedly installed outside the power slide rod 252, a third protrusion 254 symmetrically installed on the outer wall of the power slide rod 252, a fifth gear 255 slidably installed outside the power slide rod 252, a power limiting block 256 rotatably installed at the bottom of the power slide rod 252, a power limiting rod 257 fixedly installed outside the power limiting block 256, and the power limiting rod 257 slidably installed inside the first fixed plate 23.

[0030] It should be noted that, as Figure 6 and Figure 7 As shown, the second locking rack 245 can lift the power limiting block 256 through the first spring 242, causing the power slide rod 252 to rise. This allows the second protrusion 253 to engage with the notch of the first protrusion 251, thereby causing the first protrusion 251 to rotate. The rotation of the first protrusion 251 can drive the second gear 215 to rotate, thus clamping the first retainer 12 on the first placement circular plate 221. When the first retainer 12 is fully clamped, the first protrusion 251 stops rotating. Therefore, the second protrusion 253 disengages from the notch of the first protrusion 251, and the power slide rod 252 descends. This causes the power limiting block 256 to descend, thereby locking the locking compression block 244 to lock the third gear 246 and locking the second locking rack 245 to lock the fourth gear 247.

[0031] like Figure 6 As shown, the second locking rack 245 is symmetrically arranged with respect to the first fixing plate 23, and the first locking rod 243 is symmetrically arranged with respect to the first fixing plate 23.

[0032] It should be noted that, since the first retainer 12 on the first placement circular plate 221 is relatively heavy, there may still be a problem of displacement when the single position is locked during movement. Therefore, two first locking rods 243 and two second locking racks 245 are provided to achieve symmetrical locking, so that the first placement circular plate 221 is more stable in the processing after being locked.

[0033] like Figure 6 As shown, the distance between the two second locking racks 245 is greater than the length of the second slider 225.

[0034] It should be noted that the distance between the two second locking racks 245 is greater than the length of the second slider 225, in order to prevent the second locking racks 245 from being squeezed when the first slider 224 moves.

[0035] like Figures 4 to 5As shown, the outer diameter of the first retainer 12 is smaller than the diameter of the top of the first placement circular plate 221.

[0036] It should be noted that the outer diameter of the first retainer 12 is smaller than the diameter of the top of the first placement circular plate 221. This prevents the first retainer 12 from failing to descend and move when the first placement circular plate 221 is placed on it, thus improving the stability of the device.

[0037] A method for machining pockets in large copper cages, the method employing the aforementioned apparatus for machining pockets in large copper cages, includes the following steps: Step 1: First, use the hoisting mechanism to move the first retainer 12 above the first placement circular plate 221. Then, start the second telescopic rod 222 to descend, which will drive the first placement circular plate 221 and the first retainer 12 to descend. At this time, the limiting member 24 does not lock the support member 22. Then, the motor can be started to drive the fifth gear 255 to rotate, in preparation for clamping the first retainer 12. Step 2: The rotation of the fifth gear 255 drives the rotation of the second gear 215, which in turn drives the rotation of the first internal gear ring 211. The rotation of the first internal gear ring 211 drives the rotation of multiple first gears 214 and second gears 215, thereby causing the first rack 212 to slide inside the placement platform 11 to clamp the first retainer 12 until the clamping is completed. Then the fifth gear 255 can continue to rotate. Step 3: The first protrusion 251 stops rotating, and the second protrusion 253 rotates out of the notch on the first protrusion 251, so the power slide bar 252 can be lifted, which drives the power limiting block 256 and the power limiting rod 257 to descend, pressing the first locking rod 243 and the second locking rack 245, so that the position of the first placement round plate 221 is locked, thus completing the clamping and locking work. After that, the tool 19 can be started to process the first retainer 12.

[0038] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of the embodiments described above, all of which are within the protection scope of the present invention.

7. The large copper cage pocket processing device according to claim 6, characterized in that: The second locking rack (245) is symmetrically arranged with respect to the first fixing plate (23), and the first locking rod (243) is symmetrically arranged with respect to the first fixing plate (23).

8. The large copper cage pocket processing device according to claim 7, characterized in that: The distance between the two second locking racks (245) is greater than the length of the second slider (225).

9. A large copper cage pocket processing device according to claim 8, characterized in that: The outer diameter of the first retainer (12) is smaller than the diameter of the top of the first placement circular plate (221).

10. A processing method for a large copper cage pocket processing device as described in claim 9, characterized in that: Includes the following steps: Step 1: First, use the hoisting mechanism to move the first retainer (12) above the first placement circular plate (221). Then, start the second telescopic rod (222) to descend, driving the first placement circular plate (221) and the first retainer (12) to descend. At this time, the limiting member (24) does not lock the support member (22). Then, start the motor to drive the fifth gear (255) to rotate, preparing to clamp the first retainer (12). Step 2: The rotation of the fifth gear (255) drives the rotation of the second gear (215), which in turn drives the rotation of the first internal gear ring (211). The rotation of the first internal gear ring (211) can drive the rotation of multiple first gears (214) and second gears (215), thereby driving the first rack (212) to slide inside the placement platform (11) to clamp the first retainer (12) until the clamping is completed, and then continue to drive the fifth gear (255) to rotate. Step 3: The first protrusion (251) stops rotating, and the second protrusion (253) rotates out of the notch on the first protrusion (251), lifting the power slide bar (252), which drives the power limiting block (256) and the power limiting rod (257) to descend, squeezing the first locking rod (243) and the second locking rack (245), so that the position of the first placement round plate (221) is locked, thus completing the clamping and locking work. After that, the cutting tool (19) can be started to process the first retainer (12).
