Abstract

The invention relates to the field of machining clamps, and is aimed at providing a fuel pump shell machining clamp which comprises a plurality of pressing rods with claws at front ends and further comprises a positioning plate, a connecting column and a pressing rod driving device. The front end of the connecting column is connected with the rear end of the positioning plate. End through holes which are circumferentially distributed are formed in the positioning plate, and the number of the end through holes is the same as the number of the pressing rods. The pressing rods correspond to the end through holes one to one. The rear ends of the pressing rods penetrate through the end through holes and are connected with the pressing rod driving device. When the fuel pump shell machining clamp is used, the rear end of the connecting column is connected with a connecting flange of a machine tool, a fuel pump shell is placed at the front end of the positioning plate for positioning, the pressing rod driving device pulls the pressing rods to move backwards, and the claws press the front end of the flange of the fuel pump shell for clamping. The fuel pump shell machining clamp clamps the fuel pump shell for machining, and a workpiece can not deform.

Description

technical field [0001] The invention relates to the field of machining fixtures, in particular to a machining fixture for a fuel pump casing. Background technique [0002] The side wall of the housing of the fuel pump is thin and is provided with a flange; the utility model of Chinese patent application number CN201420149522.3 discloses a three-jaw clamp, which includes a cylindrical jacket and three jaws. The inside of the cover is provided with a lifting device, and the three jaws are slidably arranged on the top of the cylindrical jacket, and the three jaws are arranged in a circular array on the top of the cylindrical jacket, and the top of the lifting device is located at the top of the three clamps The central position of the annular array formed by the claws, the present invention can evenly spread the three clamping claws outwards to fix the workpiece through the front top of the cone head, and the workpiece is evenly stressed in all directions. Using the traditiona...
