High-precision clamp for machine manufacturing

Abstract

The invention discloses a high-precision clamp for machine manufacturing. The high-precision clamp comprises a base plate. The left side of the top of the base plate is fixedly connected with a datumclamping block, and the right side of the top of the base plate is fixedly connected with a clamping box. A first transmission pillar is arranged in an inner cavity of the clamping box. The two ends of the first transmission pillar are both movably connected with the inner cavity of the clamping box through bearings. The surface of the first transmission pillar is sequentially sleeved with a wormwheel and a cam from back to front. According to the high-precision clamp for machine manufacturing, the base plate, the datum clamping block, the clamping box, the first transmission pillar, the wormwheel, the cam, a motor, a second transmission pillar, a worm, a sliding plate, a transmission frame, a transmission shaft, a positioning pillar, a movable clamping plate, a sliding block, a slidinggroove, a fixing ring, a non-slip mat and a mounting plate are matched, so that the problems that most of existing high-precision clamps depend on screw rods to achieve manual clamping, workpiece clamping force is small and the working time of users is prolonged are solved, the practicability of the high-precision clamp is improved and using by the users can be facilitated.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing tools, in particular to a high-precision fixture for mechanical manufacturing. Background technique [0002] Machinery manufacturing refers to the industrial sector engaged in the production of various power machinery, lifting and transportation machinery, chemical machinery, textile machinery, machine tools, tools, instruments, meters and other mechanical equipment. The machinery manufacturing industry provides technical equipment for the entire national economy. [0003] High-precision fixtures are an indispensable tool in machining. High-precision fixtures are used to fix the processed objects. However, most of the existing high-precision fixtures rely on screw screws to manually clamp the workpiece. The working time reduces the practicability of the high-precision fixture and is not convenient for users to use. Contents of the invention [0004] The purpose of the present ...
