As shown in Fig. 2, a kind of automobile clamper of thin-walled lid part, including
For setting coaxial with lathe spindle and the chuck body 2 that is attached thereto, chuck body 2, which has, to be used for and elastic clip
The abutting end 2-1, the abutting end 2-1 of head cooperation are circular conical surface with the mating surface of elastic collet 3；
Elastic collet 3, the inner headed face of thin-walled lid part 1 is clamped in for the heart that rises, and the medial surface of the elastic collet 3 is
Internal conical surface, elastic collet 3 are removably socketed in by internal conical surface on the abutting end 2-1 of the chuck body 2；
Tensioner pushing component, for pushing elastic collet 3 so that elastic collet 3 clamps the thin-walled lid part 1.
The present invention is arranged elastic collet 3 outside chuck body 2, is made to the promotion of elastic collet 3 using tensioner pushing component
3 spreading of elastic collet clamps the inner headed face of workpiece, and the entire arc surface of workpiece is made to contact the localized contact that fixture substitutes claw, because
And Workpiece clamping will not be caused to deform in process, it is ensured that processing quality；The centering precision of the fixture of the present invention is high, bullet
Property collet 3 and chuck body 2 the not mutual spin friction in cooperation taper-face contact part, the two can only move left and right, in this way
Reduce abrasion, increases the service life of clamp body.
Optionally, as shown in Fig. 2, the abutting end 2-1 of the chuck body 2 is additionally provided with short pin 2-2, as shown in Figure 1, right
In the top of the inner headed face of thin-walled lid part 1 is additionally provided with circular hole the case where, the abutting end 2-1 of the chuck body 2 of the present embodiment
On add short pin 2-2, short pin 2-2 is used to be inserted into the circular hole on the top of the inner headed face of thin-walled lid part 1, further to thin-walled lid
Part 1 is positioned.
Preferably, the elastic collet 3 is fixedly connected by a positioning block 6 with the tensioner pushing component, the bullet
Property collet 3 there is periphery, the locating piece 6 is socketed on the periphery of the elastic collet 3；The periphery of elastic collet 3
It is equipped with axial bond, the locating piece 6 is equipped with and the matched keyway 4 of axial bond, institute with the inner headed face that elastic collet 3 coordinates
Elastic collet 3 is stated to connect with the cooperation of the keyway 4 with locating piece 6 by axial bond.
Preferably, as shown in Fig. 2, the tensioner pushing component includes rotating nut 9 and cushion block 7, the chuck body 2
The end being connect with lathe spindle is equipped with external screw thread, and the end that the chuck body 2 is connect with lathe spindle is known as connecting pin, even
It connects end and is equipped with external screw thread, the rotating nut 9 is connected on the external screw thread of connecting pin 2-3, and the cushion block 7 is slidably socketed
