Angle adjusting and clamping method for milling jig

Abstract

The invention discloses an angle adjusting and clamping method for a milling jig. The clamping method for a workpiece on the milling jig comprises the steps that a flat fixture is fixed on a top plate of a box and positioned on the top plate of the box by stepped pins; the flat fixture is fixed with the top plate of the box by bolts; the workpiece is arranged on the flat fixture; the workpiece is positioned by workpiece locating pins arranged on the flat fixture; piston rods of the cylinders move downwards to drive a pressure plate frame, pressure plate bolts and pressure plates to move downward to ensure that the pressure plates allow the workpiece to be compressed on the flat fixture; and angle adjustment of the box on the milling jig comprises a gear fine adjustment and an indexing mechanism fine adjustment. With the adoption of the method, when middle and small parts are cut, the workpiece can be quickly positioned and compressed, and a fixture inclination can be adjusted.

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,...

[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
