[0025] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0026] See also Figure 2 , Figure 2 This is a three-dimensional diagram of the best embodiment of the finger-type chuck for processing thin-walled parts of the utility model. Figure 2As shown, at least one embodiment provides a finger-type chuck for processing thin-walled parts, including: a disc body 1 and a pressing structure 4, wherein a portion of the pressing structure 4 is arranged in the disc body 1 at the position of the groove 3, and the remaining portion is arranged above the groove 3. A portion of the pressing structure 4 can be rotated by an elevator, so that the top surface of the workpiece 5 placed on the disc body 1 can be pressed by the pressing structure 4, thereby achieving an effect of relatively fixing the workpiece 5. In addition, the pressing structure 4 is against the top surface of the workpiece 5, which solves the problem of deformation caused by squeezing the side of the thin-walled workpiece 5.

[0027] Plate 1

[0028] Please continue reading Figure 2 Combined with Figure 3 , Figure 3 This is a structural diagram of the optimal embodiment of the support platform and the groove of the utility model. Figures 2 to 3 As shown, the disk body 1 is a circular disk with a certain thickness. A plurality of grooves 3 are opened on the disk body 1. A support 2 is formed between two adjacent grooves 3. The support 2 is used to place a thin-walled workpiece 5. Part of the bottom surface of the thin-walled workpiece 5 falls on the support 2, and the other part is suspended above the groove 3. The top surface of the suspended section needs to be against the holding structure 4. Specifically, the top surface of the support 2 is against the bottom surface of the workpiece 5.

[0029] Pressing structure 4

[0030] Please continue reading Figure 2 Combined with Figure 4 , Figure 4 The structure diagram of the optimal embodiment of the tabletting of the utility model is shown in FIG. Figure 2 and Figure 4 As shown, the holding structure 4 includes a plurality of pressing plates 42, and the bottom surface of the pressing plates 42 abuts against the top surface of the workpiece 5. The holding structure 4 also includes a plurality of movable rods 41, which are rotatably arranged at the position of the groove 3, and the top of the movable rod 41 is fixedly connected to the pressing plates 42. A cylinder (not shown in the figure) is arranged at the bottom of the movable rod 41, and the output end of the cylinder is rotatably connected to the bottom of the movable rod 41. The cylinder is installed in the disk body 1, and the movable rod 41 is arranged outside the disk body 1. The movable rod 41 can drive the pressing plates 42 to rotate together, and the cylinder can drive the movable rod and the pressing plates 42 to move up and down. Before placing the workpiece 5, the pressing plates 42 can be turned to a suitable position and raised. After the workpiece 5 is placed, the pressing plates 42 are turned back, and the cylinder drives the movable rod 41 to descend until the pressing plates 42 and the workpiece 5 produce a suitable extrusion force and stop.

[0031] Tablet 42

[0032] Please continue reading Figure 4 .like Figure 4As shown, the pressing piece 42 has a mounting section 421 and a pressing section 422. The mounting section 421 is fixedly connected to the top of the movable rod 41, and the pressing section 422 is pressed against the top surface of the workpiece 5. In order to prevent the surface of the workpiece 5 from being worn due to hard contact, a plurality of protective pads 423 are provided on the bottom surface of the pressing section 422. The protective pads 423 are made of hard rubber.

[0033] Please continue reading Figure 4 .like Figure 4 As shown, in order to maintain stronger stability when the pressing force between the pressing sheet 42 and the workpiece 5 is constant, a plurality of anti-skid balls 424 are arranged on the protective pad 423. The anti-skid balls 424 are hollow. A suction cup 425 is arranged between adjacent anti-skid balls 424. An adsorption hole 426 is arranged at the center of the suction cup 425, and the adsorption hole 426 is connected to the anti-skid ball 424. After the anti-skid ball 424 is squeezed and deformed by the workpiece 5, it not only has a raised anti-skid effect, but also can discharge gas from the position of the adsorption hole 426. At this time, the adsorption hole 426 is in a negative pressure state, and cooperates with the suction cup 425 to generate a certain suction force on the top surface of the workpiece 5.

[0034] In summary, by providing a pressing plate 42 that can be raised and lowered and rotated, a relative fixing effect is achieved by pressing the top surface of the thin-walled workpiece 5, effectively solving the problem of deformation caused by side pressure; by providing a protective pad 423, the contact surface is prevented from being worn during the pressing process of the workpiece 5; by providing an anti-slip ball 424 and a suction cup 425, the stability of the pressing is increased, the deviation of the workpiece 5 is avoided, and the qualified rate of the production and processing of the workpiece 5 is improved.
