[0022] The clamping station is composed of a vertical plate 11 and a clamping mechanism 2 arranged on the vertical plate 11, and the vertical plate 11 is fixed on the workbench 1, and the clamping mechanism 2 includes a slide plate 21 slidably mounted on the side of the vertical plate 11, and two groups of clamping jaws 22 are slidably mounted on the top of the slide plate 21, and the two groups of clamping jaws 22 are arranged opposite to each other, and the two groups of clamping jaws 22 are connected to a first cylinder 23 to drive the two groups of clamping jaws 22 to move closer to or away from each other, so as to fix the sheet metal parts;

[0023] The slide plate 21 is connected with a second cylinder 24, which is fixed on the vertical plate 11. The second cylinder 24 is suitable for driving the slide plate 21 to slide along the vertical plate 11. When the slide plate 21 moves to the end of the vertical plate 11, the sheet metal parts between the clamping jaws 22 can be replaced or the positions of the sheet metal parts can be switched.

[0024] like Figure 1 and Figure 3 As shown, a frame 12 is also fixed on the workbench 1, and a driving unit 3 and a grinding mechanism 4 installed below the driving unit 3 are arranged on the frame 12, and the frame 12 is located directly above the vertical plate 11, and the grinding mechanism 4 is used to deburr the edge of the sheet metal part;

[0025] The driving unit 3 includes a slider 31 slidably mounted on the frame 12, and a third cylinder 33 mounted on the slider 31, and a hanger 32 slidably penetrates the slider 31, and the output end of the third cylinder 33 is connected to the hanger 32, so that the hanger 32 is suitable for moving up and down under the drive of the third cylinder 33;

[0026] A belt drive structure (not shown in the figure) is also installed on the frame 12, and the belt drive structure is connected to the slider 31 to drive the slider 31 to move along the frame 12;

[0027] Meanwhile, the grinding mechanism 4 includes a mounting frame 41, which is fixedly connected to the bottom end of the hanger 32, and a grinding wheel 42 is installed on the upper bearing of the mounting frame 41, and a belt transmission structure (not shown in the figure) is connected to the end of the grinding wheel 42 to drive the grinding wheel 42 to rotate and deburr the edge of the sheet metal part;

[0028] In the present application, the above-mentioned belt drive structure and belt transmission structure are both prior art, please refer to the prior art for details, and no further elaboration is made here;

[0029] At the same time, a positioning part 45 is provided on the mounting frame 41 at one side of the grinding wheel 42, and the positioning part 45 is used to limit and fix the sheet metal part. The positioning part 45 is composed of two groups of limiting units and a pressing block 451 installed between the two groups of limiting units, and the horizontal position of the pressing block 451 is lower than the horizontal position of the grinding wheel 42;

[0030] The limiting unit includes a mounting block 452 fixed to the side of the mounting frame 41, and a groove is formed on the mounting block 452, a moving block 453 is slidably mounted in the groove of the mounting block 452, the moving block 453 is in the groove, a shaft 454 is connected to the top of the moving block 453, and the shaft 454 passes through the mounting block 452, and the shaft 454 is suitable for sliding synchronously with the moving block 453 in the mounting block 452;

[0031] The two groups of moving blocks 453 are respectively fixedly connected to the ends of the pressing block 451, and a spring 455 is sleeved on the shaft 454. When the pressing block 451 is acted upon by an external force, the pressing block 451 drives the moving block 453 to move synchronously and squeeze the spring 455. After the external force disappears, the moving block 453 drives the pressing block 451 to reset through the action of the spring 455.

[0032] When deburring the edge of a sheet metal part, the first cylinder 23 is driven to drive the two sets of clamps 22 to clamp and fix the sheet metal part, and then the second cylinder 24 drives the slide plate 21 to move toward the bottom of the grinding mechanism 4;

[0033] Then the belt drive structure drives the slider 31 to move, and indirectly drives the grinding wheel 42 of the grinding mechanism 4 to move to the edge of the sheet metal part, and then the third cylinder 33 drives the hanger 32 to approach the sheet metal part, and drives the grinding wheel 42 to move toward the sheet metal part;

[0034] When the grinding wheel 42 moves toward the sheet metal part, the pressing block 451 first contacts the sheet metal part, and the hanger 32 continues to move toward the sheet metal part, so that the moving blocks 453 on both sides of the pressing block 451 squeeze the spring 455. At this time, the spring 455 exerts an elastic force on the moving block 453, so that the pressing block 451 always limits the position of the sheet metal part, thereby realizing adaptive position limiting of the sheet metal part.

[0035] At the same time, the grinding wheel 42 approaches the edge of the sheet metal part, and under the action of the belt transmission structure, the grinding wheel 42 is driven to rotate to deburr the edge of the sheet metal part;

[0036] Finally, when the edge deburring of the sheet metal is completed, the hanger 32 drives the grinding mechanism 4 to move away from the sheet metal, and the pressing block 451 always applies a certain pressure to the sheet metal under the action of the spring 455. During the movement of the mounting frame 41, the pressing block 451 is gradually reset until the pressing block 451 is separated from the sheet metal.

[0037] To sum up, the pressure block 451 is driven by the hanger 32 to approach or move away from the sheet metal part, and under the action of the spring 455, the pressure block 451 always limits and presses the sheet metal part, and under the action of the grinding wheel 42, the edge of the sheet metal part is deburred, thereby realizing adaptive limiting of the sheet metal part and achieving the effect of adaptive limiting of the sheet metal part during the deburring process of the edge of the sheet metal part.

[0038] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
