Description

Technical Field

[0001] This utility model relates to the field of bearing surface grinding, and in particular to a grinding mechanism for a grinding robot. Background Technology

[0002] A bearing is a mechanical component that restricts relative motion within a desired range of motion and reduces friction between moving parts. Bearing design can allow free linear motion or free rotation about a fixed axis for moving parts, or position motion by controlling the vector of the normal force acting on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings can be broadly classified according to different methods, such as operating type, permissible motion, or the direction of the load applied to the parts.

[0003] Grinding refers to the finishing process of a workpiece by using abrasive particles coated or embedded on a grinding tool, through the relative motion between the tool and the workpiece under certain pressure. Grinding can be used to process various metallic and non-metallic materials, and the processed surface shapes include planes, internal and external cylindrical surfaces and conical surfaces, convex and concave spherical surfaces, threads, toothed surfaces, and other shaped surfaces.

[0004] In the prior art, in order to improve the automation level and production efficiency of bearing production, a grinding robot is used to replace manual grinding in the grinding process. The end of the grinding robot is clamped with a bearing through a tooling, and then the grinding robot drives the bearing to move on the grinding disc through a customized program to achieve the grinding work. However, in order to achieve high-precision machining of the bearing surface, grinding discs of different mesh sizes are required in the grinding process. To cooperate with the grinding robot's grinding work, a grinding mechanism that can automatically change grinding discs is proposed. Utility Model Content

The output end of the first motor 404 is fixedly connected to the replacement bracket 401. A clamping mechanism is provided at the other end of the replacement bracket 401. To obtain higher surface accuracy, it is necessary to... During the grinding process, different grinding platforms 501 with different grit sizes are used. When it is necessary to change the grinding platform 501, the tilting motor 103 drives the U-shaped bracket 102 to rotate to a horizontal position. The second motor 405 drives the rotating stud 406 to rotate. The rotating stud 406 drives the lifting slider 403 to rise and fall through the threaded connection.

Then, the outer bracket 204 can drive the grinding platform 501 to move and place the grinding platform 501 on the rotating disk 503. Through the cooperation of the lifting slider 403 and the replacement bracket 401, another grinding platform 501 with a different grit is clamped and transferred to the U-shaped bracket 102. After the clamping mechanism on the U-shaped bracket 102 completes the clamping of the clamping cross 504, the replacement bracket 401 is reset.

Then, it moves on the surface of the grinding platform 501 according to a predetermined trajectory, thus realizing the grinding work.

[0036] The storage mechanism includes a guide rail 301 fixedly connected to the support frame 101, an L-shaped bracket 302 slidably connected to the guide rail 301, several placement racks 303 fixedly connected to the L-shaped bracket 302, and grinding plates that can be placed and supported on the placement racks 303.

[0037] A cleaning mechanism is provided at the lower end of the support frame 101. The cleaning mechanism includes a cleaning box 601 fixedly connected to the support frame 101. A water supply pipe 602 is fixedly connected inside the cleaning box 601. Several nozzles 603 are fixedly connected to the water supply pipe 602.

During grinding, the upper grinding platform 501 is grinding, and the grinding surface of the lower grinding platform 501 is aligned with the nozzles 603. The grinding platform 501 is rinsed by pressurized water flow. This ensures that the surface is clean before the grinding platform 501 is replaced, thereby ensuring the subsequent grinding effect.

[0038] A gear ring 502 is fixedly connected to the outside of the grinding platform 501. A rotating shaft 701 is rotatably connected to the support frame 101. Rotating gears 702 are fixedly connected to the upper and lower ends of the rotating shaft 701. The rotating gears 702 can mesh with the gear ring 502.

During grinding, the U-shaped support 102 is in a vertical state. Through the setting of the rotating mechanism, the rotating motor 703 drives the rotating shaft 701 to rotate. The rotating shaft 701 drives the upper and lower rotating gears 702 to rotate. The rotating gears 702 drive the gear ring 502 to rotate. The gear ring 502 drives the grinding platform 501 to rotate. This can improve the grinding efficiency. In addition, the lower grinding platform 501 can also rotate, thus ensuring the cleaning area and cleaning effect.

[0039] Working principle:

[0040] S1: When working with the grinding robot, the flip motor 103 drives the U-shaped support 102 to rotate, making the U-shaped support 102 vertical. At this time, the rotary motor 703 drives the rotary shaft 701 to rotate, the rotary shaft 701 drives the upper and lower rotary gears 702 to rotate, the rotary gears 702 drive the gear ring 502 to rotate, and the gear ring 502 drives the grinding platform 501 to rotate. This can improve the grinding efficiency. In addition, the lower grinding platform 501 can also rotate. External water source is introduced into the water supply pipe 602 through the water inlet pipe 604. Pressurized water is sprayed through the nozzle 603 to wash the grinding platform 501, thus ensuring the cleaning area and cleaning effect.

[0041] S2: When the grinding platform 501 needs to be replaced, the tilting motor 103 drives the U-shaped bracket 102 to rotate to a horizontal position. The second motor 405 drives the rotating stud 406 to rotate. The rotating stud 406 drives the lifting slider 403 to rise and fall through a threaded connection. The lifting slider 403 drives the replacement bracket 401 to rise. The first motor 404 drives the replacement bracket 401 to rotate. The replacement bracket 401 moves above the clamping cross 504. Then, the cylinder 402 drives the clamping mechanism to open and clamp the clamping cross 504. Subsequently, the replacement motor 104 drives another clamping mechanism to open, releasing the clamping cross 504. The outer support 204 then moves the grinding platform 501 and places it on the rotating disk 503. Through the cooperation of the lifting slider 403 and the replacement bracket 401, another grinding platform 501 with a different grit is clamped and transferred to the U-shaped bracket 102. After the clamping mechanism on the U-shaped bracket 102 completes the clamping of the clamping cross 504, the replacement bracket 401 is reset, and the U-shaped bracket 102 rotates ninety degrees again to place and support the replacement grinding platform 501 on the upper end. The grinding platform 501 that has just completed the grinding work rotates to the lower end and is cleaned by the cleaning device.
