Wherein: 1. the clamping rod, 11, the external conical surface, 12, the clamping hole, 13, the containing cavity, 14, the notch, 15, the round hole, 2, the clamping rod, 21, the internal conical surface, 22, the boss, 3, the buffer spring, 4, the product to be processed.

Detailed Description

The present invention will be further described in detail with reference to the following specific examples:

in this embodiment, the product 4 to be processed is a cylindrical product with two threaded ends and a smooth middle part as shown in fig. 2, wherein the outer diameter of one end is smaller than the diameter of the clamping hole 12, the product 4 to be processed needs to be integrally fixed, and then the axial direction of the product is drilled.

As shown in fig. 1-3, a clamp suitable for a product with multiple sections of external diameters comprises a clamping rod 1 provided with an external conical surface 11, and a clamping rod 2 provided with an internal conical surface 21 and sleeved on the periphery of the clamping rod 1; the clamping rod 2 fixes the product 4 to be processed inside the clamping rod 1 through the contact fit of the outer conical surface 11 and the inner conical surface 21, and in the contact fit, the clamping rod 1 and the clamping rod 2 move relatively and finally are converted into radial pressure through axial movement; the clamping rod 1 is coaxially and sequentially provided with a clamping hole 12 and an accommodating cavity 13 in a penetrating manner, the outer conical surface 11 is arranged at one end where the clamping hole 12 is located, and the axial lines of the outer conical surface 11 and the clamping hole 12 are at least partially overlapped, so that the force of the outer conical surface 11 acting on the clamping hole 12 can be increased; the clamping rod 1 is provided with a plurality of notches 14 which penetrate through the radius of the clamping rod 1 along the axial direction, and the notches 14 start from the end surface of the clamping hole 12 and end at one side edge of the outer conical surface 11 far away from the clamping hole 12. Be equipped with buffer spring 3 between the one end that centre gripping hole 12 was kept away from to supporting rod 1 and chucking rod 2, the one end that interior conical surface 21 was kept away from to chucking rod 2 is equipped with the boss 22 that offsets with buffer spring 3, and buffer spring 3 can guarantee that the external conical surface 11 can not offset too tightly with interior conical surface 21, parts easily after treating the processing of processing product 4. The inclination angles of the outer conical surface 11 and the inner conical surface 21 are the same, the inclination angle is 10-20 degrees, and the arrangement of the outer conical surface 11 and the inner conical surface 21 at the angle can increase the force of the inner conical surface 21 acting on the clamping rod 1 in the radial direction. The end of the slot 14 remote from the clamping hole 12 is provided with a circular hole 15. The diameters of the outer conical surface 11 and the inner conical surface 21 at the end close to the holding hole 12 are larger than the diameters at the end far from the holding hole 12.
