Abstract

The invention discloses a turning fixture, and belongs to the field of machining fixtures. The turning fixture comprises a body (2), a positioning disc (7), positioning pins (10), a supporting block (8) and a pulling pressing mechanism, wherein the positioning pins (10) and the supporting block (8) are arranged on the positioning disc (7); and the pulling pressing mechanism consists of a pull rod (1), a short hinged shaft (3), a lever (4), a bush (5), a long hinged shaft (6) and a hook-shaped pressing plate (9). By the turning fixture, problems that in turning machining, the clamping efficiency of a fixture is low, workpieces are not flat or tilt due to improper clamping, and products are out-of-size are solved; actual clamping of the workpieces is guaranteed; and the clamping efficiency and the machining yield are improved.

Description

technical field [0001] The invention relates to a machining fixture, in particular to a turning 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. Such as 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 the directions ...
