A Clamping and Positioning Fixture for Arc Surface Workpieces

Abstract

The invention discloses a clamping and positioning clamp for a workpiece with a circular arc surface. The clamping and positioning clamp comprises a rotating disc and a base, wherein the rotating discabuts against the upper end of the base, three clamping devices are arranged on the upper side of the rotating disc, the clamping devices on the left side and the right side are on the same horizontal plane, the clamping device on the rear side is higher than the clamping devices on the left side and the right side, each clamping device comprises a fixed gripper and a mobile gripper, and the mobile grippers are located on the clockwise sides of the fixed grippers. According to the clamping and positioning clamp, the mobile grippers and the fixed grippers can be adjusted according to the sizeof the diameter of a round table or a conical workpiece, and then an applicable range of the clamping is expanded, moreover, the position arrangement of the three pairs of grippers can ensure that theworkpiece is clamped, and the shaking of the workpiece in the machining process is reduced, and thus the machining quality can be guaranteed, the positioning mode can be switched according to the type of the workpiece, and then the positioning effect can be ensured.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a clamping and positioning fixture for arc-shaped workpieces. Background technique [0002] Machinery manufacturing is inseparable from metal cutting machine tools, and machine tool fixtures are one of the indispensable important process equipment to ensure the quality of machining, improve production efficiency, reduce labor intensity, reduce excessive requirements for workers' skills, and realize the automation of the production process. Machine tool fixtures are widely used in the manufacturing industry. The use of a large number of special machine tool fixtures provides the necessary conditions for mass production. However, in the existing processing process, cylindrical or square workpieces are generally used for processing, while the frustum-shaped And conical workpieces are rare, so when processing frustum-shaped or conical workpieces, it is necessary to be equipped with correspond...

[0002] Mechanical manufacturing is inseparable from metal cutting machine tools, and machine tool fixtures are one of the indispensable important process equipment to ensure the quality of machining, improve production efficiency, reduce labor intensity, reduce excessive requirements for workers' skills, and realize the automation of the production process. Machine tool fixtures are widely used in the manufacturing industry, and the use of a large number of special machine tool fixtures provides the necessary conditions for mass production. However, in the existing processing process, cylindrical or square workpieces are generally used for processing, while frustum-shaped And conical workpieces are rare, so when processing frustum-shaped or conical workpieces, it is necessary to be equipped with corresponding fixtures, thereby increasing the processing cost, and the size of the workpiece is different, the size of the fixture will also be different, which gives The processing of frustum-shaped or conical workpieces brings inconvenience, and a clamping and positioning fixture for arc-shaped workpieces explained in the present invention can solve the above problems
