[0032] Furthermore, see Figures 2-3 As shown, in this embodiment, the polishing mechanism 1 includes a polishing chamber 101. At the upper end inside the polishing chamber 101, there is a three-axis system 102. A motor 103 is arranged on the three-axis system 102. The motor 103 can move along the XYZ directions under the drive of the three-axis system 102. A polishing wheel 104 capable of polishing the workpiece is sleeved on the output shaft of the motor 103; a dust discharge port 105 communicating with the dust removal mechanism 5 is opened on the rear side wall of the polishing chamber 101. A detachable baffle 106 is arranged on the dust discharge port 105. Dust discharge holes 1061 are opened on the baffle 106. The dust discharge holes 1061 are round holes, but are not limited to round holes and can also be of other shapes, such as oblong holes, etc.; and a protective door 107 that can be opened and closed is arranged on the front side wall of the polishing chamber 101. The protective door 107 is made of a through material.

[0033] Furthermore, see Figures 4-5As shown, in this embodiment, the conveying mechanism 3 adopts a double-speed chain conveyor line, which includes a support frame 301, a feeding conveyor line 302 and a material-returning conveyor line 303 arranged on the support frame 301; a limiting module 304 for limiting the fixture plate 2 is arranged on the feeding conveyor line 302. The limiting module 304 includes a first lifting cylinder 3041, and a limiting block 3042 is arranged at the front end of the output shaft of the first lifting cylinder 3041. During installation, the first lifting cylinder 3041 is fixed on the support frame 301 through the fixing plate 305; in this embodiment, two groups of the limiting modules 304 are provided, which are divided into a first limiting module 304A and a second limiting module 304B. The first limiting module 304A is arranged in the polishing chamber 101 to limit the position of the fixture plate 2 entering the polishing chamber 101. The second limiting module 304B is arranged outside the polishing chamber 101 and is located upstream of the first limiting module 304A to prevent the other fixture plates 2 loaded with workpieces from entering the polishing chamber 101 and interfering with the workpieces being polished in the polishing chamber 101; during use, the first lifting cylinder 3041 drives the limiting block 3042 to float up and down to realize the limiting of the fixture plate 2.

[0034] Further, referring to Figure 6As shown, in this embodiment, the jacking mechanism 4 includes a connecting plate 401, a jacking plate 402, and a second jacking cylinder 403; the second jacking cylinder 403 is arranged on the connecting plate 401, the jacking plate 402 is located above the connecting plate 401 and is fixed to the front end of the output shaft of the second jacking cylinder 403. The jacking plate 402 can float up and down above the connecting plate 401 driven by the second jacking cylinder 403. To prevent the jacking plate 402 from shifting during the up-and-down floating process, four groups of guide shafts 404 are provided in the jacking mechanism 4. The guide shafts 404 can all slide through the connecting plate 401, and their tops are fixedly connected to the lower end surface of the jacking plate 402. Among them, in this embodiment, the guide shafts 404 are arranged at the four top corners of the jacking plate 402. Here, it should be noted that the number of groups of the above-mentioned guide shafts 404 is only one implementation manner and does not limit the scope of this application. In actual setting, it can also be set to other numbers, such as: 2 groups, 6 groups, etc., but the minimum number cannot be less than two groups. During installation, the jacking mechanism 4 is installed adjacent to the upstream of the first limit module 304A. During use, the second jacking cylinder 403 jacks up the jacking plate 402 to lift the tooling plate 2 entering the polishing chamber 101. Among them, in order to position the tooling plate 2 entering the polishing chamber 101 and prevent the tooling plate 2 from moving on the jacking plate 402 during the polishing process, four groups of positioning pins 405 are provided on the upper end surface of the jacking plate 402, and positioning holes 201 adapted to the positioning pins 405 are opened on the lower end surface of the tooling plate 2. Here, it should be noted that when the jacking mechanism 4 is in a contracted state, that is, when the piston rod of the second jacking cylinder 403 is in a contracted state, the positioning pins 405 and the positioning holes 201 are in a disengaged state.

[0035] Further, as shown in Figure 7 As shown, in this embodiment, the dust removal mechanism 5 includes a dust removal box 501. A dust suction port 5011 connected to the dust discharge port 105 and an exhaust port 5012 are opened on the dust removal box 501. Inside the dust removal box 501 between the dust suction port 5011 and the exhaust port 5012, a filter element 502 and a suction fan 503 are provided.

[0036] The working principle of the present utility model is as follows:

[0037] During operation, when the tooling plate 2 loaded with workpieces flows onto the feeding conveyor 302 of this device, the feeding conveyor 302 continues to convey the tooling plate 2 forward, that is, continue to convey it towards the polishing chamber 101. After entering the polishing chamber 101, the second lifting cylinder 403 in the lifting mechanism 4 drives the lifting plate 402 to rise, lifting the tooling plate 2 off the feeding conveyor 302. Then, the motor 103 starts, and driven by the three-axis system 102, drives the polishing wheel 104 to polish the workpieces. After the polishing is completed, the motor 103 is turned off and reset under the drive of the three-axis system 102. At the same time, the second lifting cylinder 403 in the lifting mechanism 4 drives the lifting plate 402 to descend, so that the tooling plate 2 is placed back into the feeding conveyor 302. Then, the second lifting cylinder 403 drives the lifting plate 402 to continue descending to return to the initial state. And the tooling plate 2 is continuously conveyed downward by the feeding conveyor 302 to the next process, and after all processes are completed, it flows back to the loading position through the return conveyor 303.

[0038] Among them, during the feeding process into the polishing chamber 101, when a group of tooling plates 2 pass through the second limit module 304B, the first lifting cylinder 3041 in the second limit module 304B drives the limit block 3042 to rise, preventing the remaining tooling plates 2 from continuing to be conveyed forward. And the tooling plates 2 that pass through the second limit module 304B will be blocked by the first limit module 304A and restricted to perform polishing operations in the polishing chamber 101. After the polishing is completed, the first lifting cylinder 3041 in the first limit module 304A drives the limit block 3042 to descend, so that the tooling plates 2 in the polishing chamber 101 pass through the first limit module 304A under the conveyance of the feeding conveyor 302. Then, the first lifting cylinder 3041 in the first limit module 304A drives the limit block 3042 to rise and reset. Then, the first lifting cylinder 3041 in the second limit module 304B drives the limit block 3042 to descend. After releasing a group of tooling plates 2 to pass through, the first lifting cylinder 3041 in the second limit module 304B drives the limit block 3042 to rise and reset randomly.

[0039] In addition, during the polishing of the workpieces, the exhaust fan 503 starts. At this time, the dust generated by polishing is inhaled into the dust removal box 501 through the dust discharge port 105 and the dust suction port 5011, and then the dust is filtered by the filter element 502 and discharged from the exhaust port 5012. It should be noted here that in actual use, an exhaust pipe can be connected to the exhaust port 5012 to directly introduce it into the main exhaust pipe of the workshop or directly lead it out of the workshop for separate discharge.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
