Box angle fine location mechanism for universal fixture

Abstract

The invention discloses a box angle fine location mechanism for a universal fixture, which comprises a support mounted on a workbench, wherein the support is rotationally connected with a box; gear indexing side plates are arranged between side plates of the box and side support plates; the gear indexing side plates are fixed with the box; a circle of indexing holes are circumferentially and uniformly distributed in each gear indexing side plate; indexing location pin holes are formed in the side support plates; and after the box rotates to a set angle, indexing locating pins penetrate through the indexing locating pin holes and the indexing holes to locate the gear indexing side plates. According to the mechanism, the gear indexing side plates can be located by matching of the indexing locating pin, the indexing locating pin holes and the indexing holes, so that an inclination of the box in the fixture can be adjusted and fixed. The mechanism is good in self-locking property, ensures processing safety, greatly increases the yield, and can also save the inclination adjustment time greatly.

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
