Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a clamping device is used in axle type processing, includes clamping ring 1, and clamping hole 16 has been seted up in the axle center of clamping ring 1, and a plurality of deformation grooves 2 have been seted up to clamping ring 1's inside, and a plurality of deformation grooves 2 and clamping hole 16 intercommunication, breach 6 have been seted up to one side of clamping ring 1, and breach 6 runs through the lateral wall of clamping ring 1 to make clamping ring 1 be the C type.

A ratchet plate I7 is fixedly mounted on the end face of one side of the notch 6, an adjusting cavity 11 is formed in one side, away from the ratchet plate I7, of the notch 6, a ratchet plate II 10 is arranged inside the adjusting cavity 11, and the ratchet plate I7 is matched with the ratchet plate II 10. One end of the ratchet plate II 10 far away from the ratchet plate I7 is fixedly provided with a rotating sleeve 9, and the rotating sleeve 9 is rotatably connected with the inside of the adjusting cavity 11.

The inside of rotating sleeve 9 is provided with reset shaft 8, and reset shaft 8 runs through the lateral wall of clamping ring 1, and reset shaft 8 and rotating sleeve 9 threaded connection. Reset shaft 8 is including displacement section 12 and screw thread section 14, screw thread section 14 and the adaptation of rotating sleeve 9, and the surface of displacement section 12 is provided with spline 13, and the keyway has been seted up to the position that clamping ring 1 corresponds with spline 13, and the one end that reset shaft 8 kept away from displacement section 12 is connected with spring 15.

The side wall of the clamping hole 16 is provided with a plurality of fixing plates 3, one side of each fixing plate 3 facing the side wall of the clamping hole 16 is fixedly provided with a universal ball 4, the side wall of the clamping hole 16 is provided with a ball groove 5 corresponding to the universal balls 4, and the ball groove 5 is matched with the universal balls 4.

The working principle is as follows: when clamping the workpiece, the workpiece can be inserted into the clamping hole 16, and then each fixing plate 3 will contact with the surface of the workpiece, and then the outer circle of the clamping ring 1 near the notch 6 can be held and pressed with force, and at this time, the clamping ring 1 will be deformed, and the ratchet plate one 7 will move towards the ratchet plate two 10. The

ratchet plates

7 and 10 will be engaged with each other, so as to clamp and fix the workpiece.

The clamping ring 1 with the workpiece clamped can be placed at the clamping jaws of the chuck, the clamping jaws are controlled to clamp the clamping ring 1, and the diameter of the clamping hole 16 can be further reduced after the clamping ring 1 is subjected to extrusion force of the clamping jaws. In the process, each fixing plate 3 will adjust its angle under the cooperation of the corresponding universal ball 4 and the ball groove 5 to better contact with the surface of the workpiece and clamp the workpiece.

After the workpiece is machined, the clamping ring 1 can be detached from the chuck, and then the reset shaft 8 is pressed down, so that the angle of the reset shaft 8 cannot be changed in the moving process due to the fact that the spline 13 on the surface of the displacement section 12 is matched with the key groove. After the reset shaft 8 is pressed, the threaded section 14 will be engaged with the rotary sleeve 9, and since the angle of the reset shaft 8 is fixed, the rotary sleeve 9 will be driven to rotate by the threads, and then the ratchet plate two 10 will move away from the ratchet plate one 7 with the rotation of the rotary sleeve 9 until it is separated from the ratchet plate one 7. At this time, the notch 6 is reset, the diameter of the clamping hole 16 is enlarged, and the workpiece can be taken out.

After the workpiece is taken out, the reset shaft 8 can be released, at the moment, the reset shaft 8 can reset under the elastic force of the spring, and the rotating sleeve 9 can reset together in the process. The ratchet plate 7 and the ratchet plate 10 are engaged again at the moment, so that subsequent clamping is facilitated.
