A second motor 212 is fixedly mounted on the surface of one of the fixed plates 210. The output end of the second motor 212 is fixedly connected to the threaded rod 211. A long slot 213 is formed on the side of the processing table 1. A movable plate 214 is threadedly connected to the surface of the threaded rod 211. A connecting rod 215 is fixedly mounted between the movable plate 214 and the vertical strip plate 207. The provision of the connecting rod 215 has the effect of driving the vertical strip plate 207 to move within the slide 206.

[0029] In this embodiment: a collecting device 3 is provided on the outer wall surface of the sleeve 204, and the collecting device 3 includes a plurality of through holes 31, and the plurality of through holes 31 are annularly opened on the outer wall surface of the sleeve 204, and strip grooves 32 are opened on the inner wall surfaces on both sides of the groove 4, and a collecting box 33 is slidably connected between the two strip grooves 32. When it is necessary to prevent the burrs and debris generated by the grinding of the protrusions 205 and the rubber sealing ring from being scattered on the processing table 1, first slide the movable plate 35 so that the movable plate 35 moves inside the movable groove 34. The movement of the movable plate 35 inside the movable groove 34 will squeeze the spring 39, so that the spring 39 is compressed. At the same time, the movement of the movable plate 35 inside the movable groove 34 also drives the limit rod 36 to move. When the limit rod 36 moves to the appropriate position, the collection box 33 is slid into the inside of the strip groove 32. When the collection box 33 is located inside the strip groove 32 When the tool is in the working state, the movable plate 35 is released and the rebound force of the spring 39 is used to reset the limiting rod 36. The limiting rod 36 is reset and then inserted into the limiting hole 37.

[0034] Working principle: By setting the auxiliary device 2, when it is needed to use the device, first put the rubber sealing ring on the card slot 209 on the installation cylinder 208, and then start the second motor 212. The second motor 212 starts to drive the threaded rod 211 to rotate, and the threaded rod 211 rotates to drive the movable plate 214 to move inside the long groove 213. The movable plate 214 moves inside the long groove 213 and drives the connecting rod 215 to move. The movement of the connecting rod 215 drives the vertical strip plate 207 to move inside the slide groove 206. The vertical strip plate 207 moves inside the slide groove 206 and drives the installation cylinder 208 to move. The installation cylinder 208 The movement drives the rubber sealing ring to move. When the installation cylinder 208 moves to a position where it is located inside the sleeve 204, the second motor 212 is turned off and the first motor 203 is started. The first motor 203 starts to drive the rotating shaft 202 to rotate. The rotation of the rotating shaft 202 drives the sleeve 204 to rotate.

Through the cooperation of the above structure, no manual operation is required, which reduces production costs, and two rubber sealing rings can be processed at one time, thereby improving processing efficiency. When it is necessary to prevent the burrs and debris generated by the grinding of the grinding protrusions 205 and the rubber sealing ring from being scattered on the processing table 1, first slide the movable plate 35 to move the movable plate 35 inside the movable groove 34. The movement of the movable plate 35 inside the movable groove 34 will squeeze the spring 39, so that the spring 39 is compressed. At the same time, the movement of the movable plate 35 inside the movable groove 34 also drives the limit rod 36 to move. When the limit rod 36 moves to the appropriate position, the collection box 33 is slid into the interior of the strip groove 32. When the collection box 33 is located inside the strip groove 32, When the tool is in the working state, the movable plate 35 is released and the rebound force of the spring 39 is used to reset the limiting rod 36. The limiting rod 36 is reset and then inserted into the limiting hole 37. The limiting rod 36 and the limiting hole 37 are plugged into each other to limit the collection box 33 to the inside of the strip groove 32. Subsequently, the burrs and debris generated by the grinding protrusions 205 and the rubber sealing ring will be discharged from the through hole 31 and then fall into the inside of the collection box 33. Through the cooperation of the above structure, the purpose of collecting the debris generated by removing the burrs is achieved, thereby keeping the processing table 1 tidy during processing.
