[0017] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0018] As Figures 1-3 The utility model discloses a kind of clamping devices for metal material manufacturing, including up and down distribution fixed seat 1 and rotating seat 2, rotating seat 2 and fixed seat 1 between being provided with multiple balls 3, ball 3 is annular arrangement, rotating seat 2 and the accommodating groove corresponding ball 3 are equipped on the opposite side of fixed seat 1, multiple balls 3 are jointly installed on retainer 4, retainer 4 is positioned to multiple balls 3 to prevent ball 3 from stringing, rotating seat 2 can be rotated relative to fixed seat 1. Optionally, to support the middle part of fixed seat 1 and rotating seat 2, rotating shaft can be routinely installed at the center of rotating seat 2 and fixed seat 1.

[0019] The side of the rotating base 2 is provided with four telescopic legs 5, which are distributed along the radial direction of the rotating base 2 and are spaced apart by 90°. The telescopic leg 5 comprises a horizontal rod 6 and a vertical rod 7, which is L-shaped. The upper end of the vertical rod 7 is sleeved with a clamping sleeve 8, which can be made of rubber or silicone. The horizontal end of the vertical rod 7 is provided with a telescopic slot 9, and the horizontal rod 6 is movably inserted into the telescopic slot 9. The end of the horizontal rod 6 is provided with a protrusion 10, which is limited in the telescopic slot 9 by the protrusion 10. The spring 11 is installed between the protrusion 10 of the horizontal rod 6 and the slot of the telescopic slot 9, and is limited by the protrusion 10 and the slot of the telescopic slot 9, so that the stretching direction of the spring 11 is the same as the extension direction of the horizontal rod 6, as shown in Figure 3 The relative displacement between the vertical rod 7 and the horizontal rod 6 can be generated, that is, the telescopic leg 5 can be elongated along the radial direction of the rotating base 2.

[0020] In addition, the horizontal rod 6 and the vertical rod 7 are provided with a rotation stopping structure, for example, a wire slot is arranged on the inner wall of the telescopic slot 9 corresponding to the movement track of the protrusion 10, which limits the protrusion 10 to stop the rotation between the horizontal rod 6 and the vertical rod 7. The number of protrusions 10 corresponds to the number of wire slots, preferably two or four.

[0021] A deep groove 12 is arranged on the rotating base 2 corresponding to the horizontal rod 6, and the bottom of the deep groove 12 is provided with an internal thread. The end of the horizontal rod 6 is provided with an external thread, and the horizontal rod 6 is connected in the deep groove 12 by screwing. When the horizontal rod 6 rotates, the orientation of the vertical rod 7 can be changed. When the vertical rod 7 is upward, the clamping sleeve 8 exceeds the surface of the rotating base 2 and clamps the metal plate 13 placed on the rotating base 2. When the vertical rod 7 is downward, the clamping sleeve extends downward and does not contact the metal plate 13, so as to facilitate the edge polishing of the metal plate 13.

[0022] Preferably, the shapes of the rotating base 2 and the positioning base 1 are circular. When needed, the rotating base 2 and the positioning base can also be other shapes.

[0023] A mounting screw hole is arranged on the bottom of the positioning base 1. When the entire device is fixed, a screw hole is arranged at the same position on the workbench as the positioning base 1. The screw is screwed from the lower part of the workbench to the mounting screw hole of the positioning base 1, so as to realize the position limiting and fixing of the entire device.

[0024] In the preparation stage, the telescopic legs 5 extend upwards, the metal plate 13 to be processed is placed on the rotating seat 2, the vertical rods 7 of the telescopic legs 5 are manually pulled apart, and the metal plate 13 is automatically positioned to the center of the rotating seat 2 through the automatic rebound of the telescopic legs 5. The upper part of the device is matched with the pressure device 14, after the metal plate 13 is positioned to the center, the pressure device 14 is pressed down, so that the metal plate 13 and the device as a whole form a relatively fixed state, at this time, the vertical rods 7 are pulled apart and the cross rod is rotated by 180°, the automatic rebound of the spring 11 is utilized to make the downward extending vertical rods 7 retract to the initial state, as shown in Figure 4 At this time, the vertical rods 7 do not contact the edges of the metal plate 13, and the edges of the metal plate 13 can be polished by a polisher. During polishing, the metal plate 13 can be rotated while being polished, so that the polishing process is more convenient.

[0025] It should be noted that the pressure device 14 can be a heavy metal block or other heavy parts commonly used in the workshop. Or it can be a hydraulic device, but the hydraulic device needs to be installed above the rotating seat 2 to ensure that it does not affect the subsequent rotation of the rotating seat 2.

[0026] It should be noted that the size of the metal plate 13 to be processed is usually significantly larger than the diameter of the rotating seat 2, so the displacement of the cross rod 6 in the deep groove 12 is very small when the cross rod 6 is rotated, and the clamping and loosening process needs to create a longer displacement by the spring 11, so the displacement generated by the rotation of the cross rod 6 will not affect the use of the telescopic legs 5.

[0027] It is obvious for those skilled in the art that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
