It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-Figure 4 The utility model provides a technical solution: a clamping and positioning mechanism, the clamping and positioning mechanism comprising: a mounting plate 1, a threaded hole is opened on the surface of the mounting plate 1, a lifting screw 2 is screwed in the threaded hole, a bearing 3 is arranged at one end of the lifting screw 2, and a positioning plate 4 is arranged at the bottom of the bearing 3;

[0026] A vertical plate 5, a support shaft 6 is arranged inside the vertical plate 5, a support plate 7 is sleeved on the surface of the support shaft 6, a positioning cone 8 is arranged at the bottom of the support plate 7, a positioning block 9 is arranged on the end surface of the support shaft 6, and a positioning ring 10 is sleeved on the surface of the positioning block 9. A metal product production and testing device includes the clamping and positioning mechanism;

[0027] During use, when it is necessary to position the metal material with irregular surface, the positioning ring 10 can be removed first, and then the support plate 7 can be rotated. When the support plate 7 is parallel to the surface of the positioning plate 4, the positioning ring 10 can be used to fix it, so that the lifting screw 2 can be rotated to move the positioning plate 4 downward, so that the multiple groups of positioning cones 8 set at the bottom of the support plate 7 can be used to position the metal material with irregular surface. Multi-point positioning is achieved through multiple groups of positioning cones 8, so that the metal material can be positioned in conjunction with the mounting plate 1 to facilitate subsequent detection.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, a positioning plate 4 is provided to facilitate the positioning of the metal material. A fixing plate 11 is arranged on the side of the mounting plate 1. The fixing plate 11 can be fixed to the detection device by bolts. The mounting plate 1 is integrally in the shape of a "C"-shaped plate structure. The bearing 3 is fixedly connected to the surface of the positioning plate 4. A guide rod 12 is arranged on the surface of the positioning plate 4. The guide rod 12 passes through the mounting plate 1 and can slide up and down within the mounting plate 1. The vertical plate 5 is fixedly connected to the surface of the placement groove 13. A hole is opened on the side of the vertical plate 5, and a limiting bearing 14 is arranged in the hole. The support shaft 6 is fixedly connected to the inner ring surface of the limiting bearing 14. Multiple groups of positioning cones 8 are arranged at the bottom of the support plate 7;

[0030] During use, the positioning plate 4 can be moved downward by rotating the lifting screw 2, so as to cooperate with the mounting plate 1 to position the metal material. The setting of the guide rod 12 can limit the positioning plate 4 to avoid the problem that the positioning plate 4 also rotates when the lifting screw 2 is rotated. When it is necessary to position a metal material with an irregular surface, the support plate 7 can be rotated, and multiple groups of positioning cones 8 arranged at the bottom of the support plate 7 can be used to position the surface of the irregular metal material. The multiple groups of positioning cones 8 can achieve multi-point positioning of the material, improve the stability after positioning, and avoid deviation.

[0031] Embodiment Three

[0032] On the basis of the second embodiment, a positioning ring 10 is provided to facilitate the limitation of the support plate 7. Placement grooves 13 are opened on the surface of the positioning plate 4. There are two groups of placement grooves 13, and the two groups of placement grooves 13 are symmetrically distributed about the center line of the long side of the side of the positioning plate 4. Limiting rods 15 are arranged on the side of the vertical plate 5. There are two groups of limiting rods 15. One group of limiting rods 15 is fixedly connected directly below the positioning block 9, and the other group of limiting rods 15 is fixedly connected to the side of the positioning block 9. One end of the positioning block 9 is fixedly connected to the end face of the support shaft 6. The positioning block 9 is in the shape of a square plate structure. A damping ring 16 is sleeved on the surface of the positioning block 9. A square hole is opened on the surface of the positioning ring 10, and the positioning ring 10 can be sleeved on the positioning block 9 by means of the square hole. A limiting hole 17 is opened on the surface of the positioning ring 10, and the limiting rod 15 can be inserted into the limiting hole 17;

[0033] During use, when it is necessary to rotate the support plate 7, the positioning ring 10 can be removed, and then the support plate 7 can be rotated by means of the setting of the limiting bearing 14. After rotating to the appropriate position, the positioning ring 10 is sleeved on the positioning block 9, so that the positioning ring 10 is sleeved on the two groups of limiting rods 15 by means of the two groups of limiting holes 17. Since the positioning block 9 is square, the support shaft 6 can be fixed by the limitation of the positioning ring 10, and the support plate 7 can be prevented from continuing to rotate. The setting of the damping ring 16 can increase the friction force between the positioning ring 10 and the surface of the positioning block 9, and avoid the positioning ring 10 sliding randomly on the positioning block 9.
