[0032] The arc surface grinding mechanism includes a rotating shaft 91, a gear 92, a rack 93, a mounting frame 94, a grinding head 95 and a motor 96. Two rotating shafts 91 are rotatably mounted in the shell 1, and a gear 92 is mounted on each of the two rotating shafts 91 by a key connection. A rack 93 is mounted on one side of the coupling frame 83, and the rack 93 is meshed with the two gears 92.

[0033] When grinding the blade body 51, the operator inserts the blade body 51 between the placement grooves of the two placement racks 5 through the opening 2. The guide bevel on the placement rack 5 guides the blade body 51, making it convenient for the blade body 51 to be placed in the placement rack 5. After one side of the blade body 51 contacts the extrusion bevel on the positioning rack 71, the positioning rack 71 moves downward, and the retaining spring 72 is stretched accordingly. After one side of the blade body 51 contacts and moves forward to contact the grinding block 84, the blade body 51 will pass over the positioning rack 71 and be clamped under the action of the retaining spring 72. The positioning frame 71 moves upward, and the other side of the positioning frame 71 contacts the other side of the blade body 51. The blade body 51 can be fixed by the grinding block 84 and the positioning frame 71. Under the action of the transverse spring 6, one side of the blade body 51 in the placement frame 5 can be closely in contact with the grinding block 84. The operator controls the electric slider 82 to move back and forth along the slide rail 81. The electric slider 82 drives the coupling frame 83 and the three grinding blocks 84 to move back and forth.

The blade body 51 is displaced to improve the grinding accuracy of the blade body 51. The three grinding blocks 84 move back and forth and the grinding head 95 swing forward and backward to grind each surface of the blade body 51, so that the blade body 51 can be polished more comprehensively. After the blade body 51 is polished, the operator presses the positioning frame 71 downward, and the retaining spring 72 is stretched accordingly. The positioning frame 71 no longer limits the blade body 51. The operator takes out the polished blade body 51 and releases the positioning frame 71. Under the action of the retaining spring 72, the positioning frame 71 moves upward and resets.

The other ends of the two connecting rods 102 are respectively located in the corrugated grooves on the two corrugated groove rollers 101, and the connecting rods 102 will move up and down with the rotation of the corrugated groove slides on the two corrugated groove rollers 101.

[0035] The two rotating shafts 91 rotate forward and backward to drive the two corrugated groove rollers 101 to rotate forward and backward, and the corrugated grooves on the corrugated groove rollers 101 drive the connecting rod 102 to move up and down. The connecting rod 102 drives the sliding frame 4 and the two placement frames 5 to move back and forth up and down. The fixed guide plate 3 guides the sliding frame 4. The blade body 51 placed in the two placement frames 5 will move back and forth up and down, so that the blade body 51 can be more comprehensively contacted with the grinding block 84 and the grinding head 95, avoiding the same part of the grinding block 84 and the grinding head 95 to contact the blade body 51 for a long time, thereby extending the service life of the grinding block 84 and the grinding head 95, and at the same time, it can also improve the grinding effect of the blade body 51.

[0036] Embodiment 3: Based on embodiment 2, Figure 6-Figure 10 As shown, a clutch mechanism is also included, which is arranged on the shell 1 and the placement rack 5. The clutch mechanism is used to drive the blade body 51 to move, so as to adjust the separation or contact between the blade body 51 and the grinding block 84 and the grinding head 95. A bent rod 111 is installed at the bottom of the two placement racks 5 by bolts. The two bent rods 111 are symmetrically arranged. A roller 112 is rotatably provided at the other end of the two bent rods 111. A corrugated block 113 is installed on both side surfaces of the shell 1.

[0037] It also includes a cleaning mechanism, which is arranged on the shell 1, the coupling frame 83 and the sliding frame 4. The cleaning mechanism is used to clean the debris from grinding. The cleaning mechanism includes a square cylinder 121, an air intake check valve 122, an air outlet check valve 123, an arc-shaped porous tube 124, a hose 125, a connecting plate 126 and a piston rod 127. Two square cylinders 121 are installed at the bottom of the shell 1. The two square cylinders 121 are symmetrically arranged. One side of the two square cylinders 121 is installed with an air intake check valve 122. The air intake check valve 1 22 is connected with the square cylinder 121, and an air outlet one-way valve 123 is installed on the other side of the two square cylinders 121, and the air outlet one-way valve 123 is connected with the square cylinder 121. An arc-shaped porous tube 124 is installed on the sliding frame 4, and a hose 125 is connected between the two air outlet one-way valves 123 and the arc-shaped porous tube 124.

[0038] When the two placing racks 5 move back and forth up and down, they drive the two bent rods 111 and the roller 112 to move back and forth up and down. The two bent rods 111 and the roller 112 move back and forth up and down along the two corrugated blocks 113. After the two bent rods 111 and the roller 112 move to the raised portion of the corrugated block 113, the two bent rods 111 and the roller 112 drive the two placing racks 5 to move away from the grinding block 84 and the grinding head 95. The transverse spring 6 is stretched accordingly. The two placing racks 5 drive the blade body 51 to move away from the grinding block 84 and the grinding head 95. After the two bent rods 111 and the roller 112 move to the recessed portion of the corrugated block 113 Under the action of the transverse spring 6, the two placement racks 5 move toward the direction close to the grinding block 84 and the grinding head 95, and the two placement racks 5 drive the blade body 51 to move toward the direction close to the grinding block 84 and the grinding head 95, and so on repeatedly. During the grinding process, the blade body 51 can be continuously separated from or fitted with the grinding block 84 and the grinding head 95, so that the grinding debris on the blade body 51 can fall off, reducing the residual debris on the grinding block 84 and the grinding head 95, and avoiding the accumulation of debris affecting the grinding of the blade body 51 by the grinding block 84 and the grinding head 95, thereby further improving the grinding effect of the blade body 51.

[0039] The reciprocating movement of the connecting frame 83 drives the connecting plate 126 to move reciprocatingly, and the reciprocating movement of the connecting plate 126 drives the two piston rods 127 to move reciprocatingly in the square tube 121. When the two piston rods 127 move to one side, the outside air is drawn into one of the square tubes 121 through the air inlet check valve 122 on one side, and the air in the other square tube 121 will be discharged from the arc-shaped porous tube 124 through the air outlet check valve 123 on the other side and the hose 125 on the other side. The reciprocating movement of the two piston rods 127 can discharge the air from the arc-shaped porous tube 124 to clean the debris on the grinding block 84, the grinding head 95 and the blade body 51, thereby further reducing the residue of debris on the grinding block 84, the grinding head 95 and the blade body 51, further avoiding the accumulation of debris, and further improving the grinding effect of the blade body 51.
