The processing tool of this technical solution can fix the square tube through the square tube fixing mechanism, and horizontally grind the inner wall of the square tube through the right-angle grinding mechanism under the action of the motor movement, effectively reducing the failure rate of the inner wall grinding of the square tube, and can effectively grind the inner corner of the inner wall of the square tube, thereby effectively preventing burrs from appearing on the inner wall of the square tube.

[0004] However, the above technical solution has the following shortcomings: when the square tube is fixed to the two square tube fixing mechanisms, the first telescopic bar, the second telescopic bar and the third telescopic bar are telescoped in sequence to send the right-angle grinding mechanism to the position where the square tube needs to be processed. During the telescopic process, the first belt is not tightened by the right-angle grinding assembly and the motor and falls off or affects the processing speed of the right-angle grinding assembly.

According to the length of the square tube, the worker turns the handwheel a3 to drive the screw rod a4, and the screw rod a4 drives the mobile clamping assembly to move to a position suitable for the installation of the square tube. The square tube is also sleeved on the center grinding assembly, and one end of the center grinding assembly is rotatably set on the supporting assembly, thereby increasing the support point of the center grinding assembly, so that the center grinding assembly can avoid tilting downward under the action of its own gravity. After the grinding of the B area on the four faces of the square tube is completed, the worker removes the center grinding assembly and replaces it with the edge grinding assembly. The edge grinding assembly grinds the four corners of the square tube, thereby improving the grinding quality of the device.

[0023] Embodiment 2
