Hydraulic clamp for positioning and automatically clamping thin-walled steel sleeve through inner hole and using method thereof

Abstract

A hydraulic clamp for positioning and automatically clamping a thin-walled steel sleeve through an inner hole comprises a connecting barrel which is transparent in a left-right mode and a cylinder barrel with the open left end. The right end of the connecting barrel is coaxially fixedly connected with a flange, the flange is coaxially fixedly connected with the left end of the cylinder barrel, theinner wall of a left port of the connecting barrel is provided with a bearing for being connected with a hydraulic oil pipe, and a plurality of groups of radial telescopic clamping mechanisms with the same structure are evenly disposed on the outer ring of the cylinder barrel in the axial direction. The invention positions and clamps a thin-walled cylinder sleeve in a mode of hydraulic positioning through a plurality of supporting point inner holes, the centering precision is high, and the problem of workpiece deformation caused by uneven clamping force is solved. At the same time, since insufficient installation margin is reserved between the outer ring of the cylinder barrel and the inner hole of the thin-walled cylinder sleeve and mounting and taking out are facilitated, automatic clamping of a production line is achieved easily, human labor is replaced, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing and processing, and in particular relates to a hydraulic clamp for automatically clamping a thin-walled steel sleeve by positioning an inner hole and a use method thereof. Background technique [0002] With the rapid development of mechanical manufacturing and processing technology, the processing accuracy of some thin-walled parts is getting higher and higher. Relatively speaking, the processing efficiency of parts will decrease. In the process of automatic clamping, thin-walled parts are difficult to be installed and clamped correctly, and the workpiece is deformed due to uneven clamping force during the turning process, resulting in a decrease in the surface quality of the workpiece. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a hydraulic fixture that is simple in structure, easy to operate, can ensure...
