[0021] Depend on Figure 1 、 Figure 2 and Figure 3 As shown, the utility model includes a workbench 10 on which a power motor 1 and a grinding wheel machine 3 are fixed, a bracket 11 is provided at the output end of the power motor 1, a placement component protruding from the workbench 10 is connected to one side of the bracket 11, and a linear motor 12 is provided on the other side, and a connecting rod 121 passing through the placement component is provided at the output end of the linear motor 12, and a pressure plate 13 is provided at the protruding end of the connecting rod 121 for pressing the workpiece limited on the placement component; a dust removal component is also provided between the placement component and the grinding wheel machine 3.

[0022] Specifically, the placement component includes a support rod 14 connected to the bracket 11 on one side, and a boss 15 connected to the other side of the support rod 14. The non-connected end of the boss 15 protrudes from the workbench 10, and the protruding end of the boss 15 is provided with a limit boss 16. A limit column 17 is provided on one side of the limit boss 16, and the connecting rod 121 passes through the limit boss 16 upward; a proximity switch 2 connected to a PLC controller (not marked) is also provided on the workbench 10, and a sensing block 21 is provided at the position corresponding to the proximity switch 2 on the bracket 11; a control switch 18 connected to the power motor 1 is provided on the workbench 10, and the control switch 18 is also connected to the PLC controller.

[0023] The ash removal assembly includes a cover body 30 fixed on the workbench 10 and covering the outside of the grinding wheel machine 3, an exhaust pipe 4 provided on one side of the workbench 10, and a hair dryer 41 provided at the air inlet position of the exhaust pipe 4 on the workbench 10. The air inlet of the exhaust pipe 4 and the air outlet of the hair dryer 41 are both passed through the cover body 30. The air inlet of the exhaust pipe 4 is located between the grinding wheel machine 3 and the boss 15. The air outlet of the exhaust pipe 4 is connected to the air compressor 5. A support plate 31 is provided on the inner side wall of the cover body 30 at the position where the exhaust pipe 4 is passed through. An adjusting bolt 32 is screwed and passed through the support plate 31. A pressure block 33 is sleeved on the passing end of the adjusting bolt 32. The pressure block 33 is used to tighten the limiting exhaust pipe 4.

[0024] An arc section that fits against the outer wall of the exhaust pipe 4 is provided on one side of the pressing block 33 .

[0025] The operating principle of this utility model is as follows:

[0026] like Figures 1 to 3 As shown, before use, an air outlet of a hair dryer 41 is provided on one side of the cover body 30. At this time, the axial direction of the air outlet of the hair dryer 41 is parallel to the tangential direction of the outer circle of the grinding wheel on the grinder 3. Similarly, one end of the air inlet of the exhaust pipe 4 is passed through the cover body 30, and the screwed adjusting bolt 32 is twisted. The adjusting bolt 32 drives the pressure block 33 to move, and the outer side wall of the exhaust pipe 4 is pressed and limited by the arc section position. Since one side of the pressure block 33 is provided with an arc section that fits the outer wall of the exhaust pipe 4, the pipe wall of the exhaust pipe 4 can be prevented from being damaged by unilateral force. In this process, the air intake direction of the exhaust pipe 4 can be adjusted according to the length of the twisted extension of the adjusting bolt 32. It should be aligned with the air outlet of the hair dryer 41 and parallel to the tangential direction of the outer circle of the grinding wheel on the grinder 3, so as to facilitate the rapid collection and absorption of dust generated by grinding.

[0027] When in use, one end of the workpiece is sleeved and inserted into the limit column 17, and the non-sleeved end of the workpiece is pushed to rotate horizontally and stick to the outer wall of the limit boss 16. At this time, the control switch 18 is pressed, and the power motor 1 and the linear motor 12 are started at the same time. Then, the connecting rod 121 drives the pressure plate 13 to move in the vertical direction and presses the workpiece limited on the boss 15; during the rotation process, grinding is realized between the grinding wheel on the grinding machine 3 and the outer wall of the workpiece; during the processing, the dust generated is blown toward the exhaust pipe 4 by the hair dryer 41, and the air compressor 5 is turned on at the same time to quickly absorb the dust. It should be pointed out that in order to avoid the dust being blown everywhere, the aperture size of the exhaust pipe 4 should be larger than the inner diameter size of the air outlet position of the hair dryer.

[0028] After the sensing block 21 rotates one circle with the bracket 11, it returns to the initial position. A proximity switch 2 is provided at the initial position. That is, the sensing block 21 approaches the proximity switch 2 again after rotating one circle. At this time, the proximity switch 2 sends a signal to the PLC controller, and the PLC controller sends an instruction to the control switch 18 and turns off the power motor 1. At the same time, it also sends an instruction to the linear motor 12, and makes the connecting rod 121 drive the pressure plate 13 to move upward. At this time, the processed workpiece can be removed; repeat the above-mentioned related steps to continuously and quickly grind the outer circles of multiple workpieces; in order to improve efficiency, two limit columns 17 should be set to clamp two workpieces at a time for grinding.

[0029] It should be noted that, since the protruding end of the adjusting bolt 32 is sleeve-connected to the pressing block 33, the pressing block 33 does not rotate synchronously with the adjusting bolt 32, that is, the pressing block 33 can be held with one hand and the adjusting bolt 32 can be rotated with the other hand, so that the pressing block 33 maintains the position of the arc segment and moves toward the exhaust pipe 4, and abuts against the outer wall of the exhaust pipe 4.
