The upper end of the driving column 83 is fixedly connected with a shaft rod, the shaft rod is rotatably connected with the lower end of the L-shaped locking plate 8 through a bearing, the driving column 83 is made of a wear-resistant and mute material, and preferably an outer rubber sleeve of a manganese steel round rod, the upper end of the cutting table 1 is fixedly installed with a fan-shaped extrusion plate 84, and the fan-shaped extrusion plate 84 is located at the end of the cutting table 1 away from the laser cutting equipment 15.

[0040] The L-shaped locking plate 8 is slidably connected with the mounting groove 13, the sliding block 81 is slidably connected with the movable groove 14, and one side of the reset spring 82 abuts against one end of the mounting groove 13.

[0041] When the rotating plate 12 stops, the locking mechanism at one end of the rotating plate 12 is above the fan-shaped extrusion plate 84, at this time, the driving column 83 is in extrusion contact with the fan-shaped extrusion plate 84, the driving column 83 is moved by the fan-shaped extrusion plate 84, the driving column 83 drives the L-shaped locking plate 8 to move away from the U-shaped plate 72, in the process that the driving column 83 and the fan-shaped extrusion plate 84 approach or move away from each other, the driving column 83 and the fan-shaped extrusion plate 84 are in rolling contact, so as to reduce the friction between them, reduce wear and noise, at this time, the L-shaped locking plate 8 releases the locking of the U-shaped plate 72, and the L-shaped locking plate 8 extrudes the reset spring 82. At the same time, the locking mechanism at the other end of the rotating plate 12 is below the laser cutting equipment 15, at this time, the driving column 83 in the locking mechanism is not in contact with the fan-shaped extrusion plate 84, and the L-shaped locking plate 8 moves to be close to the U-shaped plate 72 under the action of the reset spring 82, the lower end of the L-shaped locking plate 8 is clamped at the lower end of the U-shaped plate 72, the U-shaped plate 72 cannot move downward, the driving mechanism cannot move downward, and then the first clamping mechanism and the second clamping mechanism can firmly clamp and fix the electric control box cover plate body 9.

[0042] An operation method of the electric control box cover plate processing equipment based on laser cutting comprises the following operation steps: Step one: when the rotating plate 12 rotates to the upper side of the fan-shaped extrusion plate 84, the fan-shaped extrusion plate 84 moves the driving column 83, the L-shaped locking plate 8 moves away from the U-shaped plate 72, the L-shaped locking plate 8 releases the locking of the U-shaped plate 72, the U-shaped plate 72 is pulled downward, the driving mechanism moves downward, and the driving mechanism moves the two first clamping mechanisms and the two second clamping mechanisms to approach each other. Step two: place the control box cover plate body 9 on the bearing seat 21 of the rotating plate 12 away from the laser cutting device 15, make the control box cover plate body 9 sleeve on the bearing seat 21, slowly loosen the pull of the U-shaped plate 72, and move the driving mechanism upward under the action of the upward spring 71. The driving mechanism pushes the two first clamping mechanisms and the two second clamping mechanisms to move away from each other. The clamping assembly in the two first clamping mechanisms first clamps and positions the two inner side walls on the left and right of the control box cover plate body 9. At this time, the two second clamping mechanisms clamp and position the two inner side walls in front and behind the control box cover plate body 9. The first clamping mechanism and the second clamping mechanism cooperate to firmly clamp and position the control box cover plate body 9, so that the position of the control box cover plate body 9 is consistent during each feeding, ensuring the cutting quality of the subsequent cutting; Step three: after the feeding of the control box cover plate body 9 is completed, the output shaft of the intermittent divider 11 drives the rotating plate 12 to rotate one hundred and eighty degrees. The rotating plate 12 drives the to-be-cut control box cover plate body 9 to rotate. When the driving column 83 is separated from the fan-shaped extrusion plate 84, the lower end of the L-shaped locking plate 8 is clamped at the lower end of the U-shaped plate 72 under the action of the reset spring 82, so that the U-shaped plate 72 cannot move downward, and the driving mechanism cannot move downward, thereby the first clamping mechanism and the second clamping mechanism can firmly clamp and fix the control box cover plate body 9. Until the to-be-cut control box cover plate body 9 rotates to the lower side of the laser cutting device 15, the to-be-cut control box cover plate body 9 is cut and processed by the laser cutting device 15. Step four: the rotating plate 12 drives the cut control box cover plate body 9 to rotate to the upper side of the fan-shaped extrusion plate 84. At this time, the driving column 83 contacts the fan-shaped extrusion plate 84. The fan-shaped extrusion plate 84 pushes the driving column 83 to move, so that the L-shaped locking plate 8 releases the locking of the U-shaped plate 72. By moving the driving mechanism downward, the driving mechanism pushes the two first clamping mechanisms and the two second clamping mechanisms to move close to each other, so that the two first clamping mechanisms and the two second clamping mechanisms release the clamping and fixing of the cut control box cover plate body 9. At this time, the cut control box cover plate body 9 can be unloaded, and the to-be-cut control box cover plate body 9 can be fed again. The above operation is repeated.

[0043] The feeding and unloading of the control box cover plate body 9 are simple and convenient, which greatly improves the work efficiency. The two first clamping mechanisms and the two second clamping mechanisms cooperate to firmly clamp and position the control box cover plate body 9, and the position of the control box cover plate body 9 is consistent during each feeding, so that the subsequent laser cutting device 15 can accurately cut the control box cover plate body 9; The left and right adjusting mechanisms can adjust the position of the clamping assembly according to needs, and the adjusting bolt 65 can adjust the position of the clamping claw 68 according to needs, so that the first clamping mechanism and the second clamping mechanism can clamp and position different models of the electric control box cover plate body 9, and the application range of the laser cutting device is improved.
