Box body angle adjusting device for universal fixture

Abstract

The invention discloses a box body angle adjusting device for a universal fixture, which includes a bracket mounted on a working platform as well as a box body angle fine adjustment mechanism, wherein a box body is rotationally connected onto the bracket; a box body angle fine positioning mechanism is arranged between the box body and the bracket; the box body angle fine adjustment mechanism includes racks arranged under a gear scale division lateral plate and being in threaded connection with a rack fine adjustment bolt; a rack floating structure enables the racks to move vertically, is used for fixing the racks to a position where the racks are meshed with a gear of the gear scale division lateral plate, and is arranged under the rack fine adjustment bolt; and the box body angle fine adjustment mechanism is provided with a gear locking structure used for locking the gear positions. When middle and small parts are machined, the box body angle adjusting device can be used for adjusting the dip angle of the fixture, and has the advantages of excellent self-locking performance and the capability of saving time in adjusting the dip angle.

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
