Detailed implementation mode

[0023] Please refer to Figures 1-6 , a processing device for a polytetrafluoroethylene bearing cage, comprising a workbench 1, on the surface of the workbench 1, there are arranged a clamping mechanism 2 and a drilling mechanism 3;

[0024] The clamping mechanism 2 includes a first mounting plate 201 and a cylinder 215. Both the first mounting plate 201 and the cylinder 215 are fixedly connected to the top of the workbench 1. On the surface of the first mounting plate 201, there is fixed a first motor 202. The output shaft of the first motor 202 penetrates through the first mounting plate 201 and is fixed with a first turntable 203. On the surface of the first turntable 203, there is fixed a first connecting frame 204. On the surface of the first connecting frame 204, there is fixed a second turntable 205. On the surface of the second turntable 205, there are provided four chutes 211. On the surface of the chutes 211, there is slidably connected an adjusting block 212. On the surface of the adjusting block 212, there is fixed a spring 213. On the surface of the spring 213, there is fixed a clamping plate 214. On the surface of the second turntable 205, there is fixed a second connecting frame 206. On the surface of the second connecting frame 206, there is installed an adjusting structure. One end of the cylinder 215 is fixed with a second mounting plate 216. On the surface of the second mounting plate 216, there is fixed a first slide rail 221. On the surface of the first slide rail 221, there is slidably connected a first slider 222. On the surface of the first slider 222, there is fixed a third turntable 217. The third turntable 217 is of a hollow design. On the surface of the third turntable 217, there are communicated with a plurality of air bags 218. On the surface of the third turntable 217, there is installed an air supply structure;

[0025] The bearing cage can be placed on the surface of the second turntable 205. At this time, through the adjustment structure, multiple adjusting blocks 212 can move simultaneously on the inner wall of the chute 211, so that the surface of the clamping plate 214 can be in contact with the inner wall of the bearing cage, and the spring 213 can also be compressed, so as to avoid damage to the inner wall of the bearing cage when the clamping plate 214 clamps it. After the bearing cage is clamped and fixed by the clamping plate 214, the cylinder 215 drives the second mounting plate 216 to move towards the bearing cage, so that the side surface of the bearing cage can be attached to the surface of the airbag 218. At this time, through the air injection structure, compressed air can be injected into the third turntable 217. The compressed air can enter the airbag 218 and cause the airbag 218 to expand. Through the expansion of the airbag 218, a softer clamping and fixing effect can be obtained for the bearing cage, ensuring that no scratches or damage will be caused to the surface of the bearing cage during the clamping process, so as to ensure the product quality of the bearing cage after drilling. Then, the bearing cage can be drilled by the drilling mechanism 3. And turning on the first motor 202 can drive the first turntable 203 to rotate, so that the second turntable 205 can drive the bearing cage to rotate together, thereby changing the drilling position of the bearing cage. During this period, the bearing cage will also drive the third turntable 217 to rotate through friction, so that the first slider 222 can rotate on the surface of the first slide rail 221, so as to ensure that the third turntable 217 can rotate normally.

[0026] Further, the adjustment structure on the surface of the second connecting frame 206 includes a lead screw 207. The lead screw 207 penetrates the second connecting frame 206, and the lead screw 207 is rotatably connected to the penetration part on the surface of the second connecting frame 206. One end of the lead screw 207 is rotatably connected to the surface of the second turntable 205. An operating handle 209 is fixed at one end of the lead screw 207. A sliding sleeve 208 is threadedly connected to the surface of the lead screw 207. Four connecting rods 210 are hinged to the surface of the sliding sleeve 208, and the surface of the connecting rod 210 is hinged to the surface of the adjusting block 212.

[0027] Rotating the operating handle 209 can drive the lead screw 207 to rotate. When the lead screw 207 rotates, the sliding sleeve 208 can start to move on the surface of the lead screw 207 under the influence of the thread. At the same time, the sliding sleeve 208 will also drive the connecting rod 210 to rotate, so that the connecting rod 210 can also rotate on the surface of the adjusting block 212, so as to adjust the positions of multiple adjusting blocks 212 together.

[0028] Further, the air injection structure on the surface of the third turntable 217 includes a rotary joint 220. The rotary end of the rotary joint 220 is communicated with the surface of the third turntable 217, and the fixed end of the rotary joint 220 is fixedly connected to the inner wall of the second mounting plate 216. An activity plate 223 is fixed at the bottom of the second mounting plate 216, and an air pump 219 is fixed on the surface of the activity plate 223. The air injection end of the air pump 219 is communicated with the rotary joint 220 through a pipeline.

[0029] When the third turntable 217 rotates, the rotating end of the rotary joint 220 will also rotate accordingly. The design of the rotary joint 220 can ensure the normal transportation of gas. When the air pump 219 works, compressed air can be transported into the interior of the rotary joint 220 through a pipeline. The compressed air can enter the interior of the airbag 218 through the rotary joint 220 and the third turntable 217, thereby ensuring that the airbag 218 can expand.

[0030] Furthermore, the drilling mechanism 3 includes side plates 301. The side plates 301 are fixed to the top of the workbench 1. A linear module 302 is fixed to the surface of the side plates 301. A second motor 303 is fixed to the top of the moving member on the surface of the linear module 302. The output shaft of the second motor 303 penetrates through the moving member on the surface of the linear module 302 and is fixed with a drill bit 304.

[0031] The linear module 302 can drive the moving member on its own surface to move, thereby changing the height position of the drill bit 304. When the second motor 303 is started, it can drive the drill bit 304 to rotate, enabling the drill bit 304 to normally drill the bearing cage.

[0032] Furthermore, two second slide rails 224 are fixed to the top of the workbench 1. A second slider 225 is slidably connected to the surface of the second slide rails 224. The top of the second slider 225 is fixedly connected to the bottom of the movable plate 223.

[0033] When the air cylinder 215 pushes the second mounting plate 216 to move, the movable plate 223 will drive the second slider 225 to slide on the surface of the second slide rails 224, enabling the movable plate 223 to obtain a linear guiding effect.

[0034] Furthermore, a third slide rail 227 is fixed to the surface of the first mounting plate 201. A third slider 228 is slidably connected to the surface of the third slide rail 227. The surface of the third slider 228 is fixedly connected to the surface of the first turntable 203.

[0035] When the first motor 202 drives the first turntable 203 to rotate, the third slider 228 will slide on the surface of the third slide rail 227, enabling the first mounting plate 201 to bear the weight of the first turntable 203, reducing the load on the output shaft of the first motor 202, and improving the stability when the first turntable 203 rotates.

[0036] Furthermore, a guide rod 226 is fixed to the inner wall of the chute 211. The guide rod 226 slidably penetrates through the adjusting block 212.

[0037] The guide rod 226 can provide a guiding effect on the adjusting block 212, making the movement of the adjusting block 212 more stable and also preventing the adjusting block 212 from detaching from the chute 211.

[0038] Further, a through groove is formed on the surface of the workbench 1, an intercepting grid 4 is fixed on the inner wall of the through groove, a housing 5 is fixed at the bottom of the workbench 1, a storage housing 6 is slidably connected to the inner wall of the housing 5, and the tops of the housing 5 and the storage housing 6 are both designed with open structures. A controller 7 is fixed on the surface of the workbench 1, and the controller 7 is electrically connected to the first motor 202, the linear module 302, the second motor 303 and the cylinder 215;

[0039] Through the design of the through groove on the surface of the workbench 1, the debris generated during the opening of the bearing cage can fall into the inner wall of the storage housing 6 through the through groove, and pulling out the storage housing 6 from the inner wall of the housing 5 can clean the collected debris. By setting the controller 7, the controller 7 can operate multiple devices.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
