[0029] To achieve the purpose of grinding the lower surface of the workpiece, referring to Figure 4, the lower grinding assembly 15 includes a fixed post 151. Several arc-shaped blocks 152 are fixedly connected in a ring array in the middle of the outer surface of the fixed post 151, which can limit the position of the fixed post 151 in the inner cavity of the transmission seat 141. Each of the arc-shaped blocks 152 is threaded with a fastening screw 153, which can lock the fixed post 151 in the inner cavity of the transmission seat 141.

The fastening screws 153 are threadedly connected to the inner cavity of the corresponding threaded hole 143.

[0030] To achieve the purpose of positioning the collecting mechanism 20, referring to Figure 4, the positioning mechanism 19 includes a U-shaped frame 191, and a pin 192 is slidably connected to the front of the U-shaped frame 191.

[0031] Pull the limiting frame 201 to make the two sets of horizontal plates 202 clamp into the inner cavity of the corresponding U-shaped frame 191, and then pass the pin 192 through the horizontal plate 202 to lock the limiting frame 201 into the inner cavity of the U-shaped frame 191.

[0032] To achieve the purpose of collecting debris, referring to Figure 4, the collection mechanism 20 includes a limiting frame 201. The left and right front ends of the outer surface of the limiting frame 201 are symmetrically fixed with horizontal plates 202.

The rear end of the limiting frame 201 is movably connected to the inner cavity of the discharge port 161.

[0033] Driven by the blower 17, the air discharged from the exhaust sleeve 18 causes the debris scattered on the bottom wall of the inner cavity of the collection frame 16 to float forward. During this process, the debris will pass through the discharge port 161 and fall into the inner cavity of the collection bag 203 for collection.

[0034] It should be noted that the hydraulic cylinder 5 in this utility model is model SLD30×50, the servo motor 9 and servo motor 13 are Siemens 1FT7, and the blower 17 is model T4-72.

[0035] The working principle of this utility model is as follows: When grinding of a workpiece is required, servo motor 9 and servo motor 13 are first driven to make the upper grinding disc 113 and the lower grinding disc 154 rotate in opposite directions. Then, hydraulic cylinder 5 is driven to push transmission plate 7 to move downward until the upper grinding disc 113 grinds the surface of the workpiece placed on the upper part of the lower grinding disc 154. At the same time, blower 17 is driven to exhaust a large amount of air from exhaust sleeve 18. When the debris generated during grinding falls into the inner cavity of the collection frame 16, the air force can blow the debris forward along the inner wall of the collection frame 16 until the debris slides through the discharge port 161 into the inner cavity of the collection bag 203. When it is necessary to grind the debris in the inner cavity of the collection bag 203, the air can be used to clean the debris. When the debris is being dumped, the two pins 192 are pulled out from the corresponding inner cavity of the horizontal plate 202, and then the collection bag 203 can be removed through the limiting frame 201. When the upper grinding disc 113 needs to be disassembled, the fastening screws 102 can be rotated out from the corresponding inner cavity of the threaded hole 112 through the arc-shaped through grooves 82, and then the cross 111 can be slid down from the inner cavity of the cross cavity 103. When the lower grinding disc 154 needs to be disassembled, the fastening screws 153 are rotated out from the inner cavity of the corresponding threaded hole 143 in sequence, and then the lower grinding disc 154 is pulled upward to slide the fixing column 151 out from the inner cavity of the transmission seat 141.
