Automatic quick centring clamping mechanism dedicated for axle type or cover type part

Abstract

The invention provides an automatic quick centring clamping mechanism dedicated for an axle type or cover type part. The automatic quick centring clamping mechanism can carry out automatic centring clamping on the axle type or cover type part and has the advantages of high clamping speed and wide positioning range. The automatic quick centring clamping mechanism comprises a seat body of which the section is of a U shape; a cylinder is arranged below the base; a sliding connecting rod shaft is movably arranged in a chute in the lower end surface of the seat body; the cylinder is connected with the sliding connecting rod shaft via a piston rod; two sliding blocks are symmetrically arranged on the left and the right in an upper slideway of the seat body; the seat body above the two sliding blocks is provided with a platen; two connecting rods are symmetrically arranged in the inner cavity of the seat body; one end of each connecting rod is connected with the sliding connecting rod shaft via a hinge pin; the other ends of the connecting rod are respectively connected with two sliding blocks via hinge pins; the two sliding blocks are respectively movably provided with two centring elements via T-shaped grooves; the two centring elements are respectively fixedly arranged on two sliding blocks via two locking blocks and locking bolts.

Description

technical field [0001] The invention relates to a mechanical processing device, in particular to an automatic fast centering clamping mechanism for shaft or sleeve parts. Background technique [0002] In the automatic production line or flexible machine tools of shaft or sleeve parts, the automatic centering clamping of the workpiece is currently generally using a three-jaw centering chuck, which includes manual clamping, hydraulic clamping and pneumatic clamping. The method has the disadvantages of slow clamping speed and clamping range. When changing different varieties, it is often necessary to adjust and process the clamping jaws, which affects efficiency and increases costs. Especially in the processing and positioning of the cylinder liner, the general manufacturer adopts the positioning plate method, and the positioning plate is replaced when the product is changed, which has a more prominent impact on work efficiency and cost. Therefore, it is necessary to design a ...
