[0020] The grinding assembly includes a fixed frame 101, a driving member 102, a connecting plate 103 and a grinder 104; the fixed frame 101 is arranged on the rear side of the workbench 1; a plurality of driving members 102 are fixedly connected to the front of the fixed frame 101, and the driving members 102 are electric push rods; the telescopic ends of the plurality of driving members 102 are commonly fixedly connected to a connecting plate 103; the grinder 104 is fixedly connected to the lower side of the connecting plate 103.

[0021] First, the staff placed the watch cases 3 on the carriers 9 arranged in a ring group, supported the inner side of the watch cases 3 by the carriers 9, and after the watch cases 3 were placed on all the carriers 9, the movable door on the front side of the working box 2 was opened, and the tray 4 was placed as shown in the figure. Figure 2 Push the watch case 3 and the carrier 9 into the slot 1003 in the manner shown, and then gradually push the watch case 3 and the carrier 9 into the working box 2 to realize batch loading, effectively reduce the workload of the staff, and improve the grinding efficiency. After the watch case 3 and the carrier 9 completely enter the inside of the working box 2, close the movable door on the front side of the working box 2.

[0022] Then, the driving member 102 is controlled to drive the connecting plate 103, the grinder 104 and the extrusion rod to move downward. After the grinder 104 contacts the watch case 3, the watch case 3 is grinded by the grinder 104, thereby achieving grinding of the upper side of the watch case 3.

[0023] Then, after the upper side of the watch case 3 is polished, the driving member 102 is controlled to drive the connecting plate 103 and the polishing machine 104 to move upward, and then the pneumatic clamp 7 is controlled to clamp the watch case 3. Then, the staff opens the movable door on the working box 2 and moves the supporting frame 6 upward, so that the watch case 3 and the latch 8 move upward, so that the latch 8 is separated from the supporting plate 5, and then the supporting frame 6 is moved to the outside of the working box 2, turned over 180 degrees, and then put back on the supporting plate 5, thereby realizing the batch turning operation of the watch case 3, without the need for multiple manual operations, and compared with the prior art of polishing and cutting one by one, it has a more obvious efficiency improvement; At the same time, since the watch cases 3 are of different sizes, the annular array of the carrier 9 is formed into a truncated cone with a small top and a large bottom, so as to achieve adaptation operations for various models of watch cases 3. There is no need to replace the fixed mold like the existing equipment to continue the grinding operation, which is more convenient and efficient.

[0024] The movable door on the working box 2 is made of transparent plastic material, which is convenient for the staff to observe the polishing condition of the watch case 3.

[0025] Example 2 On the basis of Example 1, Figure 1-Figure 4 As shown, a cooling component is also included, which includes a water tank 301, a water outlet pipe 302, a nozzle 303, a guide 304 and a filter 305; the water tank 301 is fixedly connected to the lower side of the workbench 1; two left-right symmetrical water outlet pipes 302 are fixedly connected and connected to the water tank 301; each water outlet pipe 302 is provided with a pump; a water flow chamber 2001 is opened on the work box 2; the other end of each water outlet pipe 302 is connected to the water flow chamber 2001 on the work box 2; a number of nozzles 303 are fixedly connected and connected in the work box 2; each nozzle 303 is connected to the water flow chamber 2001 on the work box 2; two guides 304 are clamped on the lower side of the workbench 1; each guide 304 is located at the lower side of the adjacent guide groove 1001; the lower side of each guide 304 extends into the water tank 301.

[0026] The bearing cavity 5001 is arranged in an inverted truncated cone shape, and a guide channel is opened at the edge.

[0027] During the polishing process of the watch case 3, it is necessary to spray it with coolant to achieve the effect of cooling, that is, control the pump on the water outlet pipe 302 to draw the coolant in the water tank 301 into the water flow chamber 2001 along the water outlet pipe 302, and then enter the nozzle 303 along the water flow chamber 2001, and spray the coolant onto the watch case 3 through the nozzle 303, so that the coolant can cool the watch case 3 and the grinder 104. Since the carrier 9 is arranged in a truncated cone shape with a small top and a large bottom, the carrier cavity 5001 is arranged in an inverted truncated cone shape, and a guide channel is opened at the edge, the polishing debris moves to the guide groove 1001 through the guide channel under the action of the coolant flow, and part of the coolant flows to the drainage groove 1002. When the coolant flows back to the water tank 301, the drainage groove 1002 filters the debris through the filter screen 305, so that the debris is intercepted on the filter screen 305.

[0028] The drainage surface of the drainage groove 1002 is set to be a slope with a lower left side and a higher right side; it is used to guide the mixed solution of debris and coolant to enter the guide 304 along the drainage groove 1002 to prevent the above solution and debris from remaining on the drainage groove 1002.
