[0027] Furthermore, by fixing the pneumatic clamping plate 13 to the right side of the rotating plate 12, the output shaft of the drive motor 14 can pass through the mounting base 11 and connect to the interior of the rotating plate 12. The ejector pin 2 is slidably installed on the top of the worktable 1 by adjusting the assembly 21. The pneumatic clamping plate 13 clamps the left side of the roller. Then, the position of the ejector pin 2 is adjusted to abut and limit the right side of the roller. Then, the drive motor 14 is powered on to drive the roller to rotate. The outer surface of the rotating roller is polished by the polishing assembly 4.

[0028] It should be noted that the ejector pin 2 is usually composed of a head, a rod and a tail. The head is a cone that fits into the center hole on the right side of the roller and plays a role in centering and support. It works with the pneumatic clamping plate 13 to clamp both ends of the roller. The ejector pin 2 is existing technology and its working principle is common knowledge to those skilled in the art, so it will not be described in detail here.

[0029] First, considering the question of how the rollers are polished by the polishing assembly 4, the following is presented: Figures 2-5The specific structure of the polishing assembly 4 is disclosed. The polishing assembly 4 includes a movable base 401, a support frame 402 fixedly mounted on the top of the movable base 401, a fixing block 403 fixedly mounted on the top of the support frame 402, a fixing plate 404 fixedly mounted on the top of the fixing block 403, a threaded hole on the top of the fixing plate 404, and a fastening bolt 405 threadedly connected inside the threaded hole. A connecting rod 406 is mounted on the left side of the fixing block 403, and a circular groove is formed on the back of the connecting rod 406. 407. An installation groove 408 is provided at the bottom of the inner wall of the circular groove 407. A rolling bearing 409 is rotatably installed inside the installation groove 408. A fixing post 410 is installed inside the rolling bearing 409. Both ends of the fixing post 410 penetrate the inner wall of the installation groove 408 and extend to the outside of the connecting rod 406. A polishing ball 411 is rotatably installed inside the circular groove 407. A limit cover 412 is threaded to the back of the connecting rod 406. A drain hole 413 is provided on the back of the limit cover 412.

[0030] The top of the connecting rod 406 is provided with an oil inlet 5. The bottom of the inner wall of the oil inlet 5 extends into the interior of the mounting groove 408. The circular groove 407, the mounting groove 408 and the oil inlet 5 are connected. The polishing ball 411 is installed inside the circular groove 407 and can abut against the outer surface of the rolling bearing 409.

[0031] Multiple fastening bolts 405 are provided, and the bottom of each fastening bolt 405 passes through a threaded hole and abuts against the top of the connecting rod 406, which is used to limit and fix the connecting rod 406 to the top of the support frame 402.

[0032] Furthermore, by fixing a support frame 402 to the top of the movable seat 401, and setting the height of the top of the support frame 402 to match the height of the roller after clamping and limiting, a locking slot can be formed between the fixing block 403 and the top fixing plate 404 through the fixing block 403 and the fixing plate 404. This allows the connecting rod 406 to be placed on the top of the support frame 402, so that the fastening bolt 405 threaded inside the fixing plate 404 can penetrate to the top of the support frame 402. Tightening the fastening bolt 405 causes its bottom to abut against the top of the connecting rod 406, thus fixing and limiting the connecting rod 406 to the top of the support frame 402. At this time, the head end of the connecting rod 406 is at the same horizontal height as the roller. A circular groove 407 is opened at the end of the connecting rod 406 near the roller. The circular groove 407 is adapted to the shape of the polishing ball 411. The polishing ball 411 is rotated and installed into the inside of the circular groove 407. The limiting cap 412 is screwed onto the back of the connecting rod to limit the polishing ball 411 into the inside of the circular groove 407 without affecting the rotation of the polishing ball 411. The polishing ball 411 can be limited to roll out of the circular groove 407. An installation groove 408 is opened at the bottom of the inner wall of the circular groove 407. An oil filling port 5 is opened at the top of the connecting rod 406, which extends into the inside of the installation groove 408. Then, the rolling bearing 409 is rotatably installed into the mounting groove 408 via the fixing column 410, and the outer surface of the rolling bearing 409 contacts the outer surface of the polishing ball 411. The connecting rod 406 is fixed to the front of the roller by the fastening bolt 405, and the polishing ball 411 abuts against the outer surface of the roller. When the drive motor 14 drives the clamped roller to rotate, the rotation of the roller will drive the polishing ball 411 to rotate. The polishing ball 411 can grind and polish the turning marks on the outer surface of the roller. Lubricating polishing oil is injected into the oil inlet 5 through the hose. The lubricating oil enters the mounting groove 408, and the rotation of the polishing ball 411 will drive the rolling bearing 409 to rotate. The rotation of bearing 409, in turn, allows the lubricating oil inside the mounting groove 408 to be absorbed onto the outer surface of the rolling bearing 409. The rolling bearing 409 then contacts the polishing ball 411, applying the lubricating oil to the outer surface of the polishing ball 411. This assists the polishing ball 411 in grinding and polishing the outer surface of the roller. The connecting rod 406 can move left and right via the moving component 3, allowing for comprehensive polishing of the outer surface of the roller. This achieves the desired grinding and polishing effect. Using the polishing ball 411 for grinding produces less debris and results in less material consumption, eliminating the need for frequent replacement of polishing materials and increasing the polishing efficiency of the roller.

[0033] It should be noted that lubricating polishing oil is an oil that plays a lubricating and assisting role in the polishing process. The main components commonly used are mineral oil, synthetic oil and animal and vegetable oil. Different abrasives, such as alumina, silicon carbide, diamond powder, etc., may be added according to the polishing requirements. It can remove burrs and scratches on the surface of the roller and is used to assist the polishing ball 411 in polishing.

[0034] Secondly, considering the issue of how the ejector pin 2 can move left and right on the top of the worktable 1, the following is presented: Figure 2 The specific structure of the adjustment component 21 is disclosed. The adjustment component 21 includes a fixed frame 201 fixedly installed on the top of the workbench 1. A first lead screw 202 is rotatably installed inside the fixed frame 201. A stepper motor 203 is installed through the inner wall of the fixed frame 201 on the right side of the first lead screw 202. A moving block 204 is threadedly connected to the outer surface of the first lead screw 202. A pin 2 is fixedly installed on the top of the moving block 204. The pin 2 is installed on the right side of the pneumatic clamping plate 13.

[0035] Furthermore, by fixing the fixed frame 201 to the top of the workbench 1, one end of the first lead screw 202 can rotate to the inner wall of the fixed frame 201, and the other end passes through the fixed frame 201 to install the stepper motor 203. The moving block 204 is threaded to the outer surface of the first lead screw 202. When the stepper motor 203 is started, the lead screw can be rotated, and the moving block 204 can move left and right along the first lead screw 202, driving the ejector pin 2 fixedly installed on the top of the moving block 204 to move left and right, and cooperating with the pneumatic clamping plate 13 to clamp the roller.

[0036] Finally, considering the issue of how to drive the connecting rod 406 to move left and right along the outer surface of the roller for polishing, the following is presented: Figure 1 and Figure 3 The specific structure of the moving component 3 is disclosed. The moving component 3 includes a mounting bracket 301 fixedly installed at the front end of the top of the workbench 1. A second lead screw 302 is rotatably installed inside the mounting bracket 301. A stepper motor 303 is installed on the right side of the second lead screw 302 through the inner wall of the mounting bracket 301.

[0037] The movable seat 401 is threaded to the outer surface of the second lead screw 302, and the movable seat 401 is located on the front of the pneumatic clamping plate 13.

[0038] Furthermore, by fixing the mounting bracket 301 to the top of the workbench 1, one end of the second lead screw 302 is rotatably installed inside the mounting bracket 301, and the other end of the second lead screw 302 passes through the mounting bracket 301 to install the second stepper motor 303. The moving seat 401 is threaded to the outer surface of the second lead screw 302. When the second stepper motor 303 is powered on, it can drive the second lead screw 302 to rotate, and thus the moving seat 401 can move left and right along the outer surface of the second lead screw 302, so as to achieve the effect of moving the connecting rod 406 on the top support frame 402 of the moving seat 401 left and right along the outer surface of the roller, and polishing the roller thoroughly.

[0039] In summary, the working principle of this utility model is as follows:

[0040] During the polishing process of the roller, the pneumatic clamping plate 13 clamps and fixes one end of the roller, and then the position of the ejector pin 2 is adjusted by the adjusting component 21 to clamp and fix the other end of the roller. Next, the connecting rod 406 is placed on top of the support frame 402, and the fastening bolt 405 is tightened. The bottom of the fastening bolt 405 abuts against the top of the connecting rod 406, fixing the connecting rod 406 to the top of the support frame 402. This causes the polishing balls 411 on the back of the connecting rod 406 to adhere to the outer surface of the roller. The drive motor 14 is then started to rotate the pneumatic clamping plate 13 and the roller, causing the polishing balls to... 411 is attached to the outer surface of the roller and rolls to polish the outer surface of the roller. Polishing lubricant is injected into the inside of the mounting groove 408. The rotation of the polishing ball 411 will drive the rolling bearing 409 to rotate, and apply the lubricant inside the mounting groove 408 to the outer surface of the polishing ball 411 to assist the polishing ball 411 in polishing the outer surface of the roller. The moving component 3 can drive the connecting rod 406 to move to the other end of the roller to polish the outer surface of the roller. Using the polishing ball 411 to polish the roller can produce less debris and the polishing efficiency is faster.
