Referring to fig. 1 to 5, the working method of the present invention is as follows:

grinding blade groove

(1.1) the motor 31 is started to rotate the abrasive disk 32 at a high speed.

(1.2) placing the clamp 100 into the mounting hole of the blade groove grinding seat 8 in a manner that the tool bit faces downwards, so that the end surface of the clamp 100 is tightly attached to the upper end surface of the blade groove grinding seat 8, and then screwing a locking screw (not shown in the figure) into the screw hole 83 until the clamp 100 is locked on the blade groove grinding seat 8.

(1.3) slowly pressing down the movable table 7 through external force, and polishing the milling cutter a at the joint of the front end surface and the arc surface of the grinding disc 32 after the milling cutter a descends along with the movable table 7 until a blade groove a1 meeting the requirement is polished; then, the external force is removed, and the movable stage 7 is raised to the initial position by the spring 111. Then, the locking screw at the screw hole 83 is loosened, and the jig 100 is taken out. The blade groove a1 includes a plane a11 and a curved surface a12, the plane a11 is formed by grinding the front end face of the grinding disc 32, and the curved surface a12 is formed by grinding the arc surface of the grinding disc 32.

(1.4) repeating the steps (1.2) and (1.3) after horizontally rotating the jig 100 by 180 °, thereby grinding another edge groove a1 on the milling cutter a.

Second, grinding the hollow surface of the back wall

(2.1) rotating the rear wall empty surface grinding seat 9 anticlockwise to the right, fixing the clamp 100 in the mounting hole of the rear empty surface grinding seat 9 in a mode that the tool bit horizontally faces the grinding disc 32, and screwing a locking screw (not shown in the figure) into the screw hole 93 until the clamp 100 is locked on the rear empty surface grinding seat 9.

(2.2) pressing the movable table 7 downwards by external force, rotating the rear wall hollow surface grinding seat 9 clockwise by the external force, and grinding a rear wall hollow surface a3 after rotary cutting of one rear corner surface a2 by utilizing the arc surface of the grinding disc 32; the rear wall hollow surface grinding seat 9 is rotated counterclockwise to the rightmost side. Due to the limiting effect of the limiting groove 81 and the limiting protrusion 92, the rotation angle of the rear wall hollow grinding seat 9 is approximately 90 degrees. Further, it should be noted that: when the machine is mechanically designed, when the rear wall hollow surface grinding seat 9 needs to be rotated to the right side, the central axis of the rear wall hollow surface grinding seat 9 is approximately opposite to the middle of the arc surface of the grinding disc 32 in the left-right direction.

(2.3) removing the external force applied to the movable table 7 to enable the movable table 7 to ascend to the initial position; the locking screw of the screw hole 93 is loosened and the jig 100 is taken out.

(2.4) rotating the clamp 100 by 180 degrees, then re-installing the clamp into the rear wall hollow surface grinding seat 9, and tightening a locking screw through the screw hole 93 to lock the clamp 100.

(2.5) repeating the steps (2.2) to (2.3), and grinding a rear wall hollow surface a3 after rotary cutting of the other rear corner surface a2 by using the arc surface of the grinding disc 32.

The external force mentioned in the above steps may be generated manually by a human being, or may be generated automatically by a driving device such as a hydraulic or electric device. If the device is automatically generated by the driving device, only a proper driving device needs to be additionally arranged at the corresponding position of the machine table according to the operation requirement, and the device is enabled to realize automation by virtue of the driving device, which belongs to the conventional structure in the mechanical field and is not described herein again.
