[0030] The spring 26 is sleeved on the extrusion rod 18, one end of the spring 26 is fixedly connected with the extrusion rod 18, the other end of the spring 26 is fixedly connected with the upper inner wall of the installation slot 17, the sliding rod 2 in the L-shaped cross section is slidably connected with each rectangular plate 7, the clamping plate 8 is arranged at one end of the sliding rod 2, the rubber pad is arranged on one side surface of the clamping plate 8, the two hinge rods 3 are hingedly connected with the bending frame 4, the two hinge rods 3 are hingedly connected with the two sliding rods 2 respectively, the hydraulic cylinder 5 drives the installation rod 6 to move, the bending frame 4 moves away from the support plate 13 at the same time, the inclination angles of the two hinge rods 3 change, the two sliding rods 2 relatively slide with the corresponding rectangular plates 7, and the distance between the two clamping plates 8 becomes larger, the moving rod 25 gradually contacts the arc surface of the arc block 21 in the movement process of the moving rod 25 together with the bending frame 4, the arc block 21 moves up when the surface of the moving rod 25 continuously moves against the arc surface, the extrusion rod 18 moves up at the same time under the transmission of the bending rod 22, the spring 26 deforms, the upper end of the extrusion rod 18 penetrates through the through hole and moves up against the surface of the support plate 13 in the movement process of the extrusion rod 18, and the support plate 13 and the rotating shaft 15 relatively rotate with the rectangular plate 7 at the same time.

[0031] The mounting block 28 in the back-shaped cross section is fixedly arranged on one side surface of each clamping plate 8, each mounting block 28 is connected with the sliding rod 2 through the bolt 24, the threaded groove for connecting the bolt 24 is arranged on the sliding rod 2, one end of the bolt 24 penetrates through the mounting block 28 and is screw-connected with the threaded groove on the sliding rod 2, and the clamping plate 8 and the sliding rod 2 are firmly connected together, so that the clamping plate 8 is convenient to replace when the clamping plate 8 is damaged due to long-time use.

[0032] The two recesses 29 in the symmetrical arrangement are arranged on the two sides of the machining table 1, each hinge rod 3 is arranged in the corresponding recess 29, the four fixed plates 12 in the symmetrical arrangement are fixedly installed on the machining table 1, the first reciprocating screw rod 11 is rotatably connected with two fixed plates 12, the fixed rod 10 is fixedly connected with the other two fixed plates 12, the bracket 9 is screw-connected with the first reciprocating screw rod 11, the bracket 9 is slidably connected with the fixed rod 10, the second reciprocating screw rod 27 is rotatably connected with the bracket 9, and the laser cutting head 14 is screw-connected with the second reciprocating screw rod 27.

[0033] The support 9 is provided with a rectangular opening for horizontal movement of the laser cutting head 14, and the articulated rod 3 is located in the groove 29, so that the articulated rod 3 can be effectively prevented from being in contact with the first reciprocating lead screw 11 or the fixed rod 10 during the change of the inclination angle of the articulated rod 3. When the motor drives the first reciprocating lead screw 11 to rotate, the support 9 moves along the first reciprocating lead screw 11 and simultaneously slides relative to the fixed rod 10. During the movement of the laser cutting head 14 along with the support 9, the laser cutting head 14 can cut the metal part in one direction. When the motor drives the second reciprocating lead screw 27 to rotate, the laser cutting head 14 moves along the second reciprocating lead screw 27 and cuts the metal part in another direction.

[0034] The side surface of each clamping plate 8 is fixedly connected with a limiting block 19, and the lower end of each limiting block 19 is attached to the upper surface of the support plate 13. When the rubber pads on the two clamping plates 8 are attached to the two side surfaces of the metal part to be machined, the lower surfaces of the two limiting blocks 19 are attached to the upper surface of the support plate 13, and the lower surface of the support plate 13 is attached to the upper surface of the machining table 1, so that the support plate 13 can be effectively prevented from rotating upward.

[0035] In the present application, in the initial state, the surface of the support plate 13 is attached to the upper surface of the machining table 1, and the support plate 13 is in parallel with the upper surface of the machining table 1. The metal part to be machined is placed on the support plate 13, and then the hydraulic cylinder 5 is energized to work. The hydraulic cylinder 5 drives the mounting rod 6 to move and drives the bent frame 4 to move towards the support plate 13. The inclination angles of the two articulated rods 3 change simultaneously, so that the two sliding rods 2 move simultaneously and the distance between the two sliding rods 2 decreases. In the initial state, the two clamping plates 8 are located on the two sides of the support plate 13. After the clamping plates 8 move along with the sliding rods 2, the clamping plates 8 gradually move above the support plate 13 until the rubber pads on the surfaces of the clamping plates 8 are attached to the surface of the metal part to be machined. The rubber pads on the two clamping plates 8 are attached to the two side surfaces of the metal part to be machined, so that the metal part to be machined can be automatically clamped. The friction between the rubber pads and the surface of the metal part to be machined is large, so that the metal part to be machined can be effectively prevented from sliding relative to the clamping plates 8. When the metal part to be machined is cut by the laser cutting head 14, the metal part to be machined can be prevented from sliding, so that the cutting position of the metal part to be machined can be prevented from deviating, so that the metal part to be machined can be accurately cut, and the use of the laser cutting equipment is facilitated.

[0036] When the motor drives the first reciprocating lead screw 11 to rotate, the support 9 moves along the first reciprocating lead screw 11 and simultaneously slides relative to the fixed rod 10, and the laser cutting head 14 moves along with the support 9, thereby cutting the metal part in one direction. When the motor drives the second reciprocating lead screw 27 to rotate, the laser cutting head 14 moves along the second reciprocating lead screw 27, thereby cutting the metal part in another direction. When the cutting of the metal part is completed, the hydraulic cylinder 5 drives the mounting rod 6 to move reversely, i.e., the bending frame 4 moves away from the support plate 13, the inclination angle of the two hinged rods 3 changes again, the two sliding rods 2 slide relative to the corresponding rectangular plates 7, and the distance between the two clamping plates 8 increases. When the moving rod 25 moves along with the bending frame 4, the moving rod 25 gradually contacts the arc surface of the arc block 21, and at this time, the two clamping plates 8 are located outside the support plate 13, i.e., the two clamping plates 8 no longer clamp the metal part.

[0037] When the moving rod 25 continues to move along with the bending frame 4, the surface of the moving rod 25 moves against the arc surface, thereby moving the arc block 21 upward. Under the transmission of the bending rod 22, the extruding rod 18 moves upward, the spring 26 deforms, and the upper end of the extruding rod 18 penetrates through the through hole and moves upward against the surface of the support plate 13. The support plate 13 and the rotating shaft 15 rotate relative to the rectangular plate 7, the support plate 13 changes from a horizontal state to an inclined state, and the metal part above the support plate 13 falls onto the inclined surface of the guide plate 20 under the action of gravity and finally falls into the collecting box 16. The processed metal part can be automatically taken out, and manual operation is not required, which is convenient and fast, saves time, improves the continuity of the cutting of the metal part, and improves the cutting efficiency of the metal part, thereby facilitating the use of the laser cutting equipment.

[0038] The above describes only the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical solutions and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
