[0002] The automobile front bumper trim mainly plays a decorative and protective role. In the traditional manufacturing process, the edge of the trim may be rough, have burrs, or have insufficient dimensional accuracy. In the prior art, an edge shearing machine is usually used. It can accurately trim the edge of the trim, remove excess material, make the edge smooth and flat, and improve the appearance quality of the trim. At the same time, through accurate cutting, it can ensure that the size of the trim meets the installation requirements of the automobile, so that the automobile front bumper is better fitted, and after installation, it is more beautiful and can effectively play its protective and decorative functions.

[0003] In the prior art, the waste generated by edge shearing can easily damage the workpiece, and is not conducive to the discharge of the die seat, causing the risk of jamming of the waste.

[0039] Specifically, as shown in Figure 1 , Figure 2 , the clamping assembly 34 comprises a mounting frame 34a, a clamping plate 34b, a telescopic support 34c, a tension spring 34d, an insertion block 34e and an insertion slot 34f, the mounting frame 34a is movably connected to the front side of the rotating disc 32, the clamping plate 34b is slidably connected to the inside of the mounting frame 34a, the insertion block 34e is fixedly connected to the outside of the clamping plate 34b, the insertion slot 34f is formed in the inside of the installation mold 33, and the insertion block 34e is movably connected to the inside of the insertion slot 34f.

[0040] Specifically, as shown in Figure 6 , Figure 7As shown, the telescopic support 34c is fixedly connected to the outer side of the top clamping plate 34b and the bottom clamping plate 34b, and the tension spring 34d is fixedly connected to the inner side of the telescopic support 34c.

[0041] In this embodiment: by pulling one side or both sides of the clamping plate 34b to slide outward at the same time, the installation mold 33 is inserted into the clamping plate 34b, and the other side of the clamping plate 34b is inserted into the slot 34f. Then, the clamping plate 34b is loosened, and the inner side of the clamping plate 34b is pulled back, and the outer side of the telescopic support 34c is retracted, so as to realize clamping.

[0042] Specifically, as shown in Figure 3 , Figure 4 , the buffer assembly 35 includes a nested telescopic block 35a, an electric bidirectional threaded rod 35b, a first compression spring 35c, an arc extrusion block 35d, a guide rod 35e, a force block 35f, and a second compression spring 35g.

[0044] In this embodiment: after clamping, the electric bidirectional threaded rod 35b is started, and the two nested telescopic blocks 35a are simultaneously pressed inward to contact and press the installation mold 33. When one side is subjected to a large force during shearing, the force is first transmitted to the nested telescopic block 35a in contact with the mold to make it retract, extrude the inner first compression spring 35c, drive the arc extrusion block 35d to move, push the force block 35f to slide along the guide rod 35e to both sides, and extrude the second compression spring 35g to decompose the large force into elastic potential energy and mechanical work.

[0045] Specifically, as shown in Figure 3 , the front side of the multifunctional mechanical arm 1 is provided with a machining pedestal 4.

[0046] Specifically, as shown in Figure 5 Figure 3 Figure 5 Figure 1 Figure 1 , the two sides of the machining pedestal 4 are provided with a conveying belt 5.

[0048] Working principle: before the automobile front bumper trim is processed and finished from the mold and is cut off, the cutting tool installed on the multifunctional mechanical arm 1 is repaired and replaced, the tool to be replaced is installed in the installation mold 33, and then is installed on the inner side of the installation frame 34a of the rotating disc 32.

After the other insertion block 34e is clamped into the insertion slot 34f and the pulling of the clamping plate 34b is released, the clamping plate 34b on the inner side of the clamping plate 34b rebounds, and the telescopic support 34c on the outer side of the clamping plate 34b retracts, thereby completing the clamping. After clamping, the electric bidirectional screw rod 35b can drive the two nested telescopic blocks 35a to move inward at the same time, and the installation mold 33 is attached and a certain pressure is applied, so that when a larger force is generated during cutting, the force is preferentially transmitted to the nested telescopic block 35a in contact with the installation mold 33, thereby causing the nested telescopic block 35a to retract to a certain extent and compress the first compression spring 35c on the inner side, so that the arc extrusion block 35d is driven to move and the force block 35f is driven to slide along the guide rod 35e to the two sides and compress the second compression spring 35g, thereby decomposing the larger force generated during processing into elastic potential energy and mechanical work. The above completes the installation of different tools, mainly including edge cutting, deburring, mechanical clamping jaw and slag treatment tools, etc. After installation is completed, the left transmission belt 5 is used for feeding, the clamping tool installed on the multifunctional mechanical arm 1 is used for clamping the workpiece to the machining seat 4 for edge cutting, the gear set 24 is used for driving the storage rack 22 and the extension rack 23 to rotate, the multifunctional rotating tool table 21 is used for replacing the front end tool, and the motor for driving is arranged on the inner side of the multifunctional mechanical arm 1. The orientation and angle of the tool can be adjusted by driving the electric turnover platform 25. After the extension of the front end machining tool is completed, the other three side tools are quickly stored by driving the extension rack 23 and the storage rack 22 through the gear set 24, and are attached to the multifunctional rotating tool table 21. The above operation is repeated when the tool needs to be replaced again. Finally, after the edge cutting is completed, the workpiece is transferred and discharged by the right transmission belt 5.

[0049] The above is only a preferred embodiment of the present application and does not limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
