Background technology
Power chuck be used on automatic lathe pressing from both sides, the mechanical device of pressure or fastening workpiece, be the indispensable annex of automatic lathe work.Power chuck commonly used, is applicable to (general appearance is round) and allows the radially processing of the part of clamping part to be processed clampings of radially feeling relieved by claw.But be special-shaped part for some profiles, can not adopt claw to clamp, perhaps part can not radially clamp, and can only compress vertically.For this class part is processed in turning, usually adopt separately to add the positioning compression that special tooling solves part on existing chuck, but the special tooling versatility to be poor, clamping efficient is low.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of rod-pulling type axial compression power chuck is provided, purpose is to locate fast and axial compression for some parts that can not radially clamp, and improves clamping efficient and the turning processing that realizes part.
The technical problem that the utility model solves realizes by the following technical solutions:
The design feature of a kind of rod-pulling type axial compression of the utility model power chuck is: include disk body, piston block, pull bar and pull bar pressing plate, described disk body is the cylinder discoid body, inner chamber is made as stepped hole, in macropore in described stepped hole, piston block is installed, sectional fixture locating piece in the aperture in described stepped hole; Described disk body is fixed on the lathe flange by fillister head screw; Described piston block consists of a framework by symmetrically arranged two pull bars and pull bar pressing plate by sunk screw is fastening; Described piston block is connected with the lathe pull bar with round nut by screw, is to lock with holding screw between described round nut and described screw, in the end-face hole of piston block one side, spring is installed at described round nut; Part to be processed is pressed on the end face of described positioning block of clamp by described pull bar pressing plate; Being provided with Lubricating Oil on described disk body chews.
Described two pull bars are isometric, and the external diameter of pull bar and the hole on disk body are matched in clearance.
Be provided with a through hole corresponding with part to be processed at the center of described pull bar pressing plate; The end face that is used for the compression part to be processed on described pull bar pressing plate is mutually vertical with the axis of described chuck.
Described positioning block of clamp is coaxial with disk body.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, in the utility model, piston block is connected with the lathe pull bar with round nut by screw, compresses power and has realized mechanization, has alleviated operating personnel's labour intensity, can also realize the quick-clamping of part, thereby increase work efficiency;
2, the utility model versatility is good, for different parts, only needs to change positioning block of clamp and pressing plate, can realize the clamping of part;
3, the utility model chuck structure is simple, and is easy to use, and clamp precision is high.
Description of drawings
Fig. 1 is rod-pulling type axial compression power chuck structural representation;
Fig. 2 is rod-pulling type axial compression power chuck axonometric drawing;
