Thus, by rotating the screw rod, the arm frame can move up and down. A driving motor is fixedly arranged on the arm frame for driving a deburring cone cover cutter body. The deburring cone cover cutter body is rotatably arranged on the arm frame through a bearing, and a V-belt pulley is fixedly arranged at the upper end of the deburring cone cover cutter body. The V-belt pulley and the driving V-belt pulley on the driving motor shaft are connected by a V-belt. Thus, the deburring cone cover cutter body rotates under the drive of the driving motor. A plurality of cutting tools are annularly and spacedly arranged in the deburring cone cover cutter body.

[0006] Preferably, a conical open cavity is arranged in the deburring cone cover cutter body. Chip removal grooves are annularly and spacedly arranged on the deburring cone cover cutter body for chip removal. And a tool mounting surface is arranged on the side of the chip removal groove for mounting alloy blades. The alloy blades are fixed by set screws. The cutting edge part of the alloy blades protrudes relative to the inner wall of the deburring cone cover cutter body. When the screw rod is rotated, the deburring cone cover cutter body descends to deburr the bolt fixed on the bench vise.

[0007] Preferably, an air nozzle holder is fixedly arranged on the arm frame. An air nozzle with a rubber sealing ring at the lower end is fixedly arranged on the air nozzle holder. The upper end of the air nozzle is connected with an air supply hose. The air supply hose presses the pressurized air generated by an air pump into the deburring cone cover cutter body through the air nozzle to help quickly clean the waste and discharge it from the chip removal groove, and can reduce the working temperature of the tool.

[0008] Preferably, an annular groove is provided on the inner wall of the upper end of the deburring cone cover tool body for the rubber sealing ring to be rotatably installed therein, and grease is provided at the joint between the rubber sealing ring and the deburring cone cover tool body, so that the relative rotation of the rubber sealing ring and the deburring cone cover tool body is smoother on the premise of ensuring good sealing.

[0009] Preferably, for more convenience and labor saving, a motor for driving the screw rod to rotate is fixedly provided at the upper end of the vertical arm.

[0010] Preferably, for more labor saving, a hand wheel is fixedly provided at the upper end of the screw rod, so that it can be rotated conveniently and labor savingly, and the cost is lower.
