Rapid-positioning and pneumatic-compressing universal fixture capable of slightly adjusting inclination angle

Abstract

The invention discloses a rapid-positioning and pneumatic-compressing universal fixture capable of slightly adjustable inclination angle, which comprises a bracket mounted on a workbench, wherein a box body is rotationally connected with the bracket; a flat fixture is fixed on a top plate of the box body and used for mounting a workpiece; the box body is provided with a pneumatic compressing mechanism for compressing the workpiece; and a box body angle adjustment device is arranged between the box body and the bracket. The universal fixture can rapidly position and press the workpiece when medium and small parts are machined; the inclination angle of the fixture can be adjusted; and the universal fixture has the advantages of good universality, high positioning accuracy, good self-locking property, and the like.

Description

technical field [0001] The invention relates to a universal clamp for milling machines. Background technique [0002] Milling machine fixtures in the prior art usually adopt the following four schemes: [0003] A. For different angle requirements, use wire cutting to make simple fixtures with fixed angles; [0004] B. A fixed universal fixture parallel to the plane formed by the X and Y axes of the machine tool; [0005] C. A fixed universal fixture parallel to the plane formed by the X and Z axes of the machine tool; [0006] D. A simple general-purpose angle fixture is formed by combining sheets. [0007] However, Type A fixtures are not universal—wasting materials; the parallelism of Type A, B, C, and D fixtures relative to the X and Z axes of the machine tool needs to be adjusted with a dial indicator every time the machine is installed—wasting time; A , B, C, and D fixtures use screws to cooperate with the pressure plate to press the workpiece-wasting time; A, B, C,...

Problems solved by technology

[0007] However, Type A fixtures are not universal—wasting materials; the parallelism of Type A, B, C, and D fixtures relative to the X and Z axes of the machine tool needs to be adjusted with a dial indicator every time the machine is installed—wasting time; A , B, C, and D fixtures use screws to cooperate with the pressure plate to press the workpiece-wasting time; A, B, C, and D fixtures have no standard reference benchmark when setting the tool-wasting time; D fixtures do not adjust the angle. Fine adjustment - waste of time; Poor angle locking of class D fixtures - poor security
