A Turning Pull-press Fixture

Abstract

The invention discloses a turning tension and compression fixture, which includes a body, the body is a hollow cylindrical structure, the center hole of the front end is slightly smaller, and a positioning sleeve is arranged in the center of the flange; The positioning sleeve is evenly distributed with a number of support blocks, and a pull rod hole is arranged beside the support block, and a pull rod is fitted in the pull rod hole; the front end of the pull rod is connected with a pull claw through a hinge shaft, and the pull claw passes through the pull claw hole on it. It is movably connected to the support block by a rotating shaft; the end of the pull rod is connected to the pull plate through a pull rod pad. The purpose of the invention is to solve the problem of low fixture clamping efficiency in turning processing, and the unevenness and warping of the workpiece due to improper clamping, resulting in unqualified product dimensions; During processing, problems such as large ellipse, unstable size, and product deformation; ensure correct clamping of the workpiece, improve clamping efficiency and processing pass rate.

Description

technical field [0001] The invention relates to a machining fixture, in particular to a turning tension-pressing fixture. Background technique [0002] In the machining industry, turning is a commonly used machining method. Fixtures are used when the workpiece needs to be fixed during machining operations. like Figure 1-Figure 2 As shown, the traditional clamping scheme is to use a three-jaw clamp for clamping; the body 2 is installed on the rotating spindle of the lathe, and the T-shaped block 104 adjusts the telescopic position of the clamp claw 103 so that the positioning surface of the workpiece 101 is aligned with the three clamp claws 103 The locating surface of the workpiece is fit and clamped, and the workpiece hanging angle 102 must avoid the clamp jaw 103. In this clamping method, since the clamp claws 103 have no directional reference, the operator has to visually avoid the clamp to interfere with the clamped workpiece, and the clamping efficiency is low; and t...
