[0038] The polishing device 4 adjacent to the tightening device 3 is as follows Figure 5 The polishing device 4 shown in the figure includes a third fixed seat 41, and the third fixed seat 41 is provided with a polishing displacement driving assembly 42, wherein Figure 4As shown, the polishing displacement drive assembly 42 includes a linear drive motor 421 fixed on the third fixed seat 41 and a linear drive guide 422 connected to the linear drive motor 421, the linear drive guide 422 is connected to the first connection seat 44, the first connection seat 44 is fixed with a first motor 441 and a first slide rail 442, the first slide rail 442 is slidably connected to the second connection seat 45, the second connection seat 45 and the first motor 441 are linked by a joint bearing 443, in this embodiment, the first motor 441 can realize the left and right movement of the second connection seat 34 by forward and reverse rotation, and then drive the left and right movement of the polishing seat 43 to realize the left and right polishing operation. The second connection seat 45 is driven by the linear drive motor 421 to achieve the up and down displacement; the second connection seat 45 is connected to a polishing seat 43 for sleeved polishing belt 2, specifically, as shown in FIG. Figure 6 As shown, the polishing seat 43 includes a first polishing piece 431 and a second polishing piece 432 symmetrically arranged, the upper ends of the first polishing piece 431 and the second polishing piece 432 are both provided with a mounting portion 433, the lower ends of the first polishing piece 431 and the second polishing piece 432 are polishing portions 434, and the first polishing piece 431 and the second polishing piece 432 are also provided with a second inner groove 4341 that runs through the mounting portion 433 and the polishing portion 434, and the polishing belt 2 is connected to the second inner groove 4341. In order to increase the flexibility of the utility model, a first pneumatic finger 451 is also provided on the second connecting seat 45, and the first pneumatic finger 451 is provided with two output arms that can be opened left and right, the first polishing piece 431 and the second polishing piece 432 are respectively fixedly connected to the output arms, and a first inner groove 4331 fixedly connected to the output arm is provided on the mounting portion 433, and a second inner groove 4341 for accommodating the polishing belt 2 is also provided on the first polishing piece 431 and the second polishing piece 432. The setting of the first inner groove 4331 can make the connection between the first polishing piece 431 and the second polishing piece 432 and the first pneumatic finger 451 more stable and less prone to deviation problems. The setting of the second inner groove 4341 can position the polishing belt 2 to prevent the polishing belt 2 from falling off during operation. In order to increase the positioning of the ceramic shell, a positioning groove body 4342 is provided on the first polishing piece 431 and the second polishing piece 432. The positioning groove body 4342 can quickly position the ceramic shell, which facilitates polishing operations and improves efficiency.

[0039] In addition, if the first polishing piece 431 and the second polishing piece 432 are not aligned to limit the relative opening displacement, they are prone to fall off. Therefore, in this embodiment, a limiter 46 is provided on the first pneumatic finger 451. The two ends of the limiter 46 extend to form limiter arms 461. The two limiter arms 461 are respectively placed at the connection between the first pneumatic finger 451 and the first polishing piece 431 and the second polishing piece 432.

Furthermore, the limitation of the working range of the polishing belt 2 by the two can be controlled to avoid the inability to polish the inner wall of the ceramic shell due to excessive opening.

[0040] In order to increase the polishing belt 2 can maintain a straight state during the polishing operation, such as Figure 7 As shown, both side edges of the polishing seat 43 are provided with a clamping assembly 47, and the clamping assembly 47 includes a clamping seat 471 fixedly arranged on the side edge of the polishing seat 43, a "T"-shaped first sliding groove 472 is formed on the clamping seat 471, and a clamping block 473 whose shape matches the first sliding groove 472 is arranged on the first sliding groove 472, and a clamping cylinder 474 is fixedly arranged on one side of the clamping seat 471, and the clamping cylinder 474 is connected to the clamping block 473. The clamping assembly 47 can be provided to clamp the polishing belt 2, so that the polishing belt 2 between the two clamping assemblies 47 can be in a tightened state, thereby improving the polishing effect, and the "T"-shaped first sliding groove 472 can ensure the directional movement of the clamping block 473, and will not fall off, thereby ensuring the stability of the clamping operation;

[0041] One end of the polishing belt 2 is wound on the discharging turntable 11, and the other end of the polishing belt 2 is connected to the recovery turntable 12 after passing through the first control wheel group 32, the polishing belt pulling assembly 33, the polishing seat 43 and the second control wheel group 34 in sequence for recovery. A polishing surface is provided on the polishing belt 2, and the polishing surface faces outward relative to the polishing seat 43 and is placed on the second inner groove 4341 of the polishing part 434, so that the polishing belt 2 can cooperate with the polishing part 434 to realize the polishing operation of the workpiece.

[0042] When the polishing belt 2 is connected to the second inner groove 4341, the polishing parts 434 of the first polishing piece 431 and the second polishing piece 432 form a polishing operation area. During the operation, the first pneumatic finger 451 can drive the first polishing piece 431 and the second polishing piece 432 to open and tighten relative to each other. Fig. 9As shown, when the first polishing member 431 and the second polishing member 432 are relatively opened, a certain distance is formed between them, and the polishing belt 2 sleeved on the first polishing member 431 and the second polishing member 432 will be lengthened, that is, the polishing operation area will be increased, so that it can adapt to products of different sizes and increase the practicality of polishing. Similarly, if such a large polishing operation area is not required, such as Figure 8 As shown, it is only necessary to contract the first pneumatic finger 451 so that the first polishing piece 431 and the second polishing piece 432 are tightened toward each other.

[0043] The working principle of the utility model is briefly described as follows: the polishing belt 2 is used as the main polishing material in this embodiment. Before the operation, the polishing belt 2 is first rolled and installed on the discharge turntable 11, and then the polishing belt 2 passes through the first through groove 311, the first guide wheel 322, the clamping member 335, the first polishing member 431 and the second inner groove 4341 of the second polishing member 432, the third guide wheel 341, the fourth guide wheel 342, the fifth guide wheel 344 and the recovery turntable 12 in sequence. It should be noted that the polishing surface of the polishing belt 2 is placed outward relative to the second inner groove 4341. During the operation, the first pneumatic finger 451 is used to adjust the gap between the first polishing member 431 and the second polishing member 432. The polishing operation area formed by the two can adapt to the ceramic shell to be polished, and then the recovery motor 13 starts to straighten the polishing belt 2, and then the clamping cylinder 474 pushes the clamping block 473, so that the clamping block 473 clamps the polishing belt 2, and the recovery motor 13 stops at the same time. Since a clamping block 473 is provided on both sides of the first polishing member 431 and the second polishing member 432, the polishing belt 2 sleeved between the two clamping blocks 473 will be in a straightened state, and then the linear drive motor 421 drives the first polishing member 431 and the second polishing member 432 to move downward, so that the ends of the first polishing member 431 and the second polishing member 432 extend into the ceramic shell to be polished. The positioning groove 4342 arranged on the first polishing piece 431 and the second polishing piece 432 can adapt to the structure inside the ceramic shell, so that the first polishing piece 431 and the second polishing piece 432 can be inserted more quickly without damaging the ceramic shell. Then the first motor 441 pneumatically drives the polishing belt 2 to move left and right to polish the inner wall of the ceramic. Similarly, the linear drive motor 421 drives the up and down reciprocating movement so that the polishing belt 2 can polish the side wall of the ceramic shell. After the polishing is completed, the polishing surface of the polishing belt 2 will be worn out. At this time, it is necessary to replace the complete surface of the polishing belt 2 to replace the worn surface. Then the two clamping blocks 473 loosen the polishing belt 2, and the second pneumatic finger 334 drives the clamp The tightening piece 335 clamps the polishing belt 2, and the first cylinder 331 is started to move the clamping piece 335 downward. At the same time, the clamping piece 335 also pulls the polishing belt 2 downward, so that the polishing belt 2 can be pulled out of the discharge turntable 11 to a certain length, which can be set according to the length of the polishing operation area. Then the clamping piece 335 is released, and after the first cylinder 331 is reset, the clamping piece 335 clamps the polishing belt 2 again. At this time, the polishing belt 2 between the clamping piece 335 and the clamping piece is in a relaxed state. Then the recovery motor 13 is started to straighten the polishing belt 2, and then the clamping piece presses the polishing belt 2, so that the polishing operation area of ​​the polishing belt 2 can be replaced, and then the above-mentioned polishing operation can be repeated.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
