Specific implementation

[0026] The utility model is further explained in combination with the drawings and specific embodiments, so that the person skilled in the art can better understand the utility model and can be implemented, but the embodiment is not as the limitation of the utility model.

[0027] Refer to Figure 1 - Figure 7 The utility model discloses a numerical control machine tool cutting device, including laser cutting bed 11 and the mobile cutting frame 12 of sliding lap on the top outside surface of laser cutting bed 11, the laser cutting device 13 of sliding sleeve connection on the outside surface of mobile cutting frame 12, motor one 14 of detachable installation on the inside wall surface of mobile cutting frame 12, be provided with threaded rod on the output end of motor one 14, the outside surface screw thread movable sleeve connection of threaded rod has sliding block 141, the inside wall surface of sliding block 141 is fixedly installed with motor two 142, the output end outside surface of motor two 142 is fixedly connected with rotating disc 143, and the inside wall surface of rotating disc 143 is fixedly connected with extrusion clamping tooth 144;The inside wall surface of laser cutting bed 11 movable lap has clamping tooth lap station 112, and the surface movable lap of rotating disc 143 and extrusion clamping tooth 144 is on the outside surface of clamping tooth lap station 112;

[0028] After the laser cutter 13 is used for a period of time, the lifting plate 122 is lowered in cooperation with the lifter 121, and the turntable 143 on one end of the lifting plate 122 is staggered and lapped on one side edge position of the clamping lap table 112, and the motor two 142 on the inner wall surface of the sliding block 141 is used to rotate the turntable 143, so that the extrusion clamping teeth 144 on the surface of the turntable 143 slide on the surface of the clamping lap table 112. The inclined angle and the spikes on the surface of the extrusion clamping teeth 144 extrude the accumulated weld layer on the top surface of the clamping lap table 112 upward. Since the contact surface between the clamping lap table 112 and the accumulated weld layer is small, the stress surface is small, and the hard points between the accumulated weld layer and the clamping lap table 112 are different, under the extrusion of the extrusion clamping teeth 144 on one end of the extrusion clamping teeth 144, the accumulated weld layer is extruded and peeled off from the top surface of the clamping lap table 112, and the side surface of the extrusion clamping teeth 144 will produce friction between the surface of the clamping lap table 112, thereby polishing and cleaning the residual melting points between the side surfaces of the clamping lap table 112. The characteristics of the hard points, small contact surface and small stress surface between the accumulated weld layer and the clamping lap table 112 make the accumulated weld layer quickly peel off under the extrusion of external force, avoiding the accumulation of steel solution on the clamping lap table. With the continuous accumulation of the solution, it will gradually rise and thicken. After the solution cools down, a relatively thick accumulated weld layer will be formed on the surface of the clamping lap table.
