Detailed Description

Reference numerals: 1, a base; 1.1 a second conical surface; 1.2 upright posts; 2, a spring; 3 a clamping unit; 3.1 circular ring part; 3.2 clamping the block; 3.2.1 supporting plate; 3.2.2 first conical surface; 3.2.3 third conical surface; 3.2.4 connecting plates; 4, workpiece; 5, a dust cover; 11 a rotatable mounting base; 12 is lowerable and rotatable.

The following detailed description is made with reference to the accompanying drawings: the utility model provides an automatic change production is work piece clamping device for assembly line, includes base 1 and clamping unit 3, base 1 has the columniform hole of placing, it still has stand 1.2 to place the downthehole, stand 1.2 has the accommodation hole, the accommodation hole has held spring 2, clamping unit 3 include ring portion 3.1 and with a plurality of grip blocks 3.2 of ring portion fixed connection, have the gap between two adjacent grip blocks 3.2, grip block 3.2 including can with place the first circular conical surface 3.2.2 of hole top butt, with the arc surface form's that ring portion 3.1 is connected connecting plate 3.2.4 and the backup pad 3.2.1 that is used for supporting the work piece, the lower surface butt of backup pad 3.2.1 spring 2.

The clamping blocks 3.2 are four, and the four clamping blocks 3.2 are distributed in an annular shape at equal intervals. The top end of the cylindrical placing hole is provided with a second conical surface 1.1 which can be abutted with the first conical surface 3.2.2. The upright 1.2 and the placement holes are both cylindrical. A plurality of grip blocks 3.2 with ring portion 3.1 integrated into one piece, grip block 3.2 include with the cambered surface form's that ring portion is connected connecting plate 3.2.4 and the holding head of being connected with connecting plate 3.2.4, the holding head is including the backup pad 3.2.1 that is used for supporting the work piece, the holding head still has first circular conical surface 3.2.2. The clamping head further comprises a third conical surface 3.2.3, the first conical surface 3.2.2 is located at the bottom end of the clamping head, and the third conical surface 3.2.3 is located at the top end of the clamping head. The clamping head further comprises an arc surface used for abutting against the side face of the workpiece, and the plurality of clamping heads surround and form a placing space used for placing the workpiece and located above the supporting plate 3.2.1.
