Automatic centering clamp for disk sleeve parts

Abstract

The invention relates to the field of mechanical auxiliary devices, in particular to an automatic centering clamp for disk sleeve parts. The automatic centering clamp for the disk sleeve parts comprises a hydraulic cylinder and a clamp body and is characterized in that a piston is arranged in the hydraulic cylinder and is connected with a hinge through a piston rod which is fixedly connected with the piston; three grooves which are distributed at an angle of 120 degrees are formed in the hinge; an opening of each groove is far away from the center of the hinge; the three grooves are connected with a clamping claw through bumps of three stirring forks which are arranged on the clamp body and correspond to the three grooves; small holes are formed in the positions, on the upper side and the lower side of the piston, on the hydraulic cylinder. The automatic centering clamp for the disk sleeve parts is high in concentricity accuracy, simple in structure, high in positioning accuracy, high in universality degree and long in service life; the centering and clamping functions are reliable, a workpiece is convenient to load and unload, the working efficiency is improved, and the labor intensity of workers is alleviated.

Description

technical field [0001] The invention relates to the field of mechanical auxiliary devices, in particular to an automatic centering fixture for disk sleeve parts. technical background [0002] Disc sleeve parts are very common mechanical parts, and there are many processing methods for them, such as turning with workpiece rotation or boring turning with tool rotation. However, in the design of combined machine tools, it is often encountered disc sleeve parts with high quality, large batches, and high concentricity requirements between the inner hole and the outer circle of the part. With the development of science and technology and the high requirements of users on the machining accuracy of machine tools, the processing of disc sleeve parts often encounters bottlenecks. And the processing cannot be completed in one clamping, because the inner hole and the outer circle are clamped and processed multiple times, it is difficult to guarantee the geometric accuracy of the parts,...

Problems solved by technology

However, in the design of combined machine tools, it is often encountered disc sleeve parts with high quality, large batches, and high concentricity requirements between the inner hole and the outer circle of the part.

With the development of science and technology and the high requirements of users for the machining accuracy of machine tools, the processing of disc sleeve parts often encounters bottlenecks. And the processing cannot be completed in one clamping. Due to the multiple clamping processing of the inner hole and the outer circle, it is difficult to guarantee the geometric accuracy of the parts, and the workpiece cannot be automatically positioned and clamped, which increases the labor intensity of the workers.
