Abstract

The invention discloses a box angle fine adjustment mechanism for a universal fixture, which comprises a support mounted on a workbench, wherein side support plates are arranged on the left side and the right side of the support; a box is rotationally connected between the two side support plates; gear indexing side plates are arranged between side plates on the two sides of the box and the side support plates; the gear indexing side plates are fixed with the box; racks are arranged below the gear indexing side plates and are threaded connection with rack fine adjustment bolts; rack floating structures capable of allowing the racks to float up and down and fixing the racks at gear engagement positions of the gear indexing side plates are arranged below the rack fine adjustment bolts; and the box angle fine adjustment mechanism is provided with a rack locking structure for locking positions of the racks. According to the mechanism, the racks are separated from or engaged with gears to achieve coarse adjustment and fine adjustment of an inclination; the adjustment accuracy is high; the adjustment is convenient; the inclination adjustment time is greatly saved; the box angle fine adjustment mechanism is good in self-locking property, so that the processing safety is ensured; and the yield is also increased 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,...
