Detailed Description
As shown in figures 1 and 2, the cold extrusion universal joint shaft sleeve processing clamp comprises a body 1 and a pull rod 2, wherein the body 1 consists of an installation part 1-1 and a fixed part 1-2, the body 1 is cylindrical, the installation part 1-1 is positioned at the front end of the body 1, a through hole 1-1-1 is formed in the middle of the installation part 1-1, the front end of the through hole 1-1-1 is provided with a taper 1-1-2, an expansion groove 1-1-3 is formed in the installation part 1-1, the rear end of the installation part 1-1 is provided with the fixed part 1-2, the tail part of the fixed part 1-2 is provided with a thread, the other end of the fixed part is provided with a conical surface two 1-2-1, a screwing hole 1-2-2 is formed in the conical surface two 1-2-1, the pull rod 2 is arranged in the through hole 1-1-1 of the installation part 1-1, the end part of the pull rod 2 is provided with a taper III 2-1 which is matched and installed with the taper I1-1-2 at the front end of the through hole 1-1-1. The outer circle of the mounting part 1-1 is step-shaped. The expansion grooves 1-1-3 penetrate through the whole installation part 1-1, and the expansion grooves 1-1-3 are arranged vertically. The tail part of the pull rod 2 is provided with a connecting hole 2-2, and the connecting hole 2-2 is connected with the cylinder. The fixing part is arranged on a machine tool through threads, sleeves with different inner diameters can be arranged on the step surface of the mounting part 1-1, the pull rod 2 moves backwards through the contraction of the air cylinder after the mounting is finished, the expansion groove 1-1-3 is pushed open through the mutual acting force of the taper III 2-1 and the taper I1-1-2, the tension is directly transmitted to the inner wall of the sleeve to be clamped, the design of the conical surface II 1-2-1 prevents the sleeve from interfering with the fixing part 1-2 in the clamping process, meanwhile, the fixing part 1-2 is convenient to screw, and the clamping device is suitable for large-batch and quick clamping.
It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
