Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

Examples of such embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present patent, but should not be construed as a limitation on the present patent.

Example 1

1 and 2, an X-ray inspection fixture suitable for cylindrical products with different diameters includes a base 1, a chute 4 is opened on the top of the base 1, and a fixed plate 3 is fixed at both ends of the chute 4. The same screw 5 is rotated and inserted on the two fixing plates 3, and one end of the screw 5 is fixed with a rotating handle 13. The screw 5 has two threads of the same length, and the two threads are in opposite directions. There are two sliders 6 , the sliders 6 form a sliding fit with the chute 4 , a vertical plate 7 is fixed on the top of the slider 6 , and a clamping mechanism is fixed on the vertical plate 7 .

The clamping mechanism includes two guide rods 10, and the guide rods 10 are movably plugged on the vertical plate 7. The two ends of the guide rod 10 are respectively fixed to the limit plate 8 and the clamping plate 11, and the guide rod 10 is close to the clamping plate 11. A spring 9 is sleeved on one end, and two clamping strips 12 are fixed on the outer wall of one side of the clamping plate 11. The two clamping strips 12 are provided with inclined surfaces, and rubber pads are glued on the inclined surfaces. The bottom of the base 1 is fixed with a support rack 2.

The working principle of this embodiment: the setting of the screw 5 can drive the two sliders 6 to move toward each other when the staff rotates the rotating handle 13, so that the distance between the two clamping mechanisms is reduced, and the workpiece is clamped, which is suitable for cylinders of different diameters. The shape of the product improves the flexibility of adjusting the clamping distance. After the clamping bar 12 is in contact with the surface of the clamping member, the guide rod 10 can use the clamping reaction force to cooperate with the clamping plate 11 to compress and buffer the spring 9, thereby increasing the clamping force. The transition ability of the force prevents the clamping force from damaging the appearance of the clamping piece, forms a flexible clamping, and protects the appearance of the clamping piece.
