When processing the ceramic brush roller, the No. 1 rod 2 is driven to rotate by the motor, so that the upper surface and the lower surface of the ceramic brush roller can be processed without repositioning, which is conducive to improving the processing efficiency;

[0029] The arc length of the arc support plate 5 is greater than the arc length of the arc clamping plate 4, so that ceramic brush rollers of different diameters can be first positioned on the side wall of the round block 3, and the ceramic brush rollers can be fixed in cooperation with the arc clamping plate 4;

[0030] In the above, a plurality of threaded push rods 6 are penetrated and rotatably arranged on the arc support plate 5 and the arc clamping plate 4; when clamping ceramic brush rollers of different diameters, there will be a problem of small contact area between the ceramic brush roller and the arc support plate 5 and the arc clamping plate 4. At this time, by rotating the threaded push rod 6, one end of the threaded push rod 6 is pressed against the surface of the ceramic brush roller, thereby increasing the contact area with the ceramic brush roller and improving the clamping stability; wherein, in order to reduce damage to the surface of the ceramic brush roller, a rubber layer is also arranged at the end of the threaded push rod 6.

[0031] In the above, the driving structure of the arc clamp 4 can be: a vertical slide groove 20 is opened on the side of the round block 3 away from the No. 1 rod 2, a slider 21 is slidably arranged in the slide groove 20, and the arc clamp 4 is fixedly connected to one side of the slider 21; a screw rod 7 is rotatably arranged in the slide groove 20 along the length direction of the slide groove 20, the screw rod 7 passes through the slider 21, and one end of the screw rod 7 is arranged outside the round block 3; when the ceramic brush roller is placed on the top of the arc support plate 5, the screw rod 7 is rotated to drive the slider 21 to move downward, so that the slider 21 slides downward along the slide groove 20, so that the slider 21 drives the arc clamp 4 to move downward, thereby clamping the ceramic brush roller.

[0036] When the rectangular housing 1 moves to a specified height, in order to reduce the force on the electric cylinder and increase the service life of the electric cylinder, slots 15 are equidistantly provided on the outer wall of the guide rod 12, and the bottom of the slots 15 is arranged obliquely upward; plug plates 16 are penetrated and slidably connected on both sides of the base 13, and a plug block 17 is fixedly connected to one side of the plug plate 16 located inside the base 13, and the bottom of the plug block 17 is also arranged obliquely upward; a push plate 18 is fixedly connected to one end of the plug plate 16 located outside the base 13, and a spring 19 is fixedly connected between the push plate 18 and the base 13. When the plug block 17 is inserted into the slot 15, the spring 19 is in its original length state; when working, when the electric cylinder When the rectangular housing 1 is driven to move upward, the guide rod 12 will move upward. At this time, the plug block 17 and the slot 15 will slide, so that the plug block 17 drives the plug plate 16 to move in the direction away from the guide rod 12. At this time, the spring 19 is stretched. When the guide rod 12 moves to the specified height, the elastic force of the spring 19 will drive the plug plate 16 to move in the direction close to the guide rod 12, so that the plug block 17 is inserted into the slot 15. Since the tops of the slot 15 and the plug block 17 are both in a horizontal state, the plug block 17 will limit the downward movement of the guide rod 12.

After one end of the ceramic brush roller is placed on the top of the arc support plate 5 on the round block 3 of the first rod 2, the screw rod 7 is rotated so that the screw rod 7 drives the slider 21 to move downward, so that the slider 21 slides downward along the slide groove 20, so that the slider 21 drives the arc clamping plate 4 to move downward, thereby clamping the ceramic brush roller, so that the ceramic brush roller is clamped between the arc support plate 5 and the arc clamping plate 4, and the ceramic brush roller is positioned; the second rod 8 is pushed again so that the second rod 8 drives the round block 3 to move in the direction close to the ceramic brush roller, and then the clamping member is used to clamp the other end of the ceramic brush roller, so that the stability of the ceramic brush roller during processing can be improved; by rotating the threaded top rod 6, one end of the threaded top rod 6 is against the surface of the ceramic brush roller, thereby increasing the contact area with the ceramic brush roller and improving the stability of clamping;

[0038] Start the electric cylinder, so that the electric cylinder drives the rectangular shell 1 to move up and down, thereby changing the overall height of the ceramic brush roller, which facilitates the lathe tool to process the ceramic brush roller; when the electric cylinder drives the rectangular shell 1 to move upward, the guide rod 12 will move upward. At this time, the plug block 17 and the slot 15 will slide, so that the plug block 17 drives the plug plate 16 to move away from the guide rod 12. At this time, the spring 19 is stretched. When the guide rod 12 moves to the specified height, the elastic force of the spring 19 will drive the plug plate 16 to move toward the guide rod 12, thereby inserting the plug block 17 into the slot 15. Since the top of the slot 15 and the plug block 17 are both in a horizontal state, the plug block 17 will limit the downward movement of the guide rod 12. At this time, the electric cylinder can stop working, and the rectangular shell 1 can also maintain its position.
