Description
Technical field
The present invention relates to a kind of machining fixture.The present invention is applicable to the machining fixture of the critical component such as valve, valve gap.
Background technology
In the man-hour that adds of the critical components such as valve, need to process respectively valve seat mount pad in each end face of valve body, passage and valve body.At present, adding man-hour to each end face, passage, valve seat mount pad in valve body, when an end face and one end passage and side valve seat mount pad process, valve body be unloaded from lathe the clamping again that turns around, then the end face of the other end and passage and valve seat mount pad are processed.One of its shortcoming is: clamping process affects valve body process velocity, and working (machining) efficiency is low; Two of its shortcoming is: each clamping all location errors, produces coaxial error, affect valve body machining accuracy to the processing of two valve seat mount pads in valve body two end faces and valve body.
Summary of the invention
The object of the invention is the shortcoming existed for prior art, provide a kind of clamped one time to realize the whole machined surface of valve body, working (machining) efficiency is high, automatic rotary calibration processing unit (plant) that Product Precision is high.
Technical scheme of the present invention comprises chuck, claw, and claw is made up of upper clipping claw and lower claw; Mainly upper clipping claw is movably arranged in the axis hole of clamping piston by installation shaft, and clamping piston is arranged in the clamping cylinder on chuck; Lower gripper is connected with the shaft hole matching on rolling disc by installation shaft, and rolling disc is axially arranged on chuck by locating piece, and rolling disc is radial to be coordinated with chuck installing hole inwall is dynamic; Polygon cylinder is made at rolling disc external cylindrical surface middle section position, the chuck of polygon cylinder side is provided with the first oil cylinder and the second oil cylinder, first in-oil cylinder first piston end and the second in-oil cylinder second pistons end extend in a plane of polygon cylinder respectively, and first piston and the second piston adopt hydraulic system interaction to control.
In above technical scheme, the side of first piston and the second pistons end is shaped with the inclined-plane cooperatively interacted with the plane of polygon cylinder respectively, and the opposite side of first piston end is shaped with the inclined-plane parallel with the second pistons end inclined-plane.
In above technical scheme, between rolling disc radial direction and chuck installing hole inwall, journal bearing is housed, between rolling disc end face and chuck installing hole bottom surface, plane bearing is housed; Installation end spherical bearing between the installation shaft end face of upper gripper and the axis hole bottom surface of clamping piston.
The present invention's beneficial effect is compared with prior art that workpiece is installed on rolling disc by gripper by clamping cylinder, rolling disc adopts the first oil cylinder and the second oil cylinder pushing to rotate, clamped one time can complete the processing of multiple, decrease the clamping workpiece time, avoid clamping workpiece error, have that working (machining) efficiency is high, mismachining tolerance is few, machining accuracy advantages of higher.
