Automatic clamping and positioning mechanism suitable for multiple types of connecting rods

Abstract

The invention relates to an automatic clamping and positioning mechanism suitable for multiple types of connecting rods. The automatic clamping and positioning mechanism comprises a bottom plate, wherein a first sliding plate is slidably mounted at one end of the top side of the bottom plate, a U-shaped base is mounted on the top side of the first sliding plate, the first sliding plate and one ends of two linkage rods are rotatably mounted, the two linkage rods are symmetrically arranged, the other ends of the two linkage rods are rotationally installed with two symmetrically-arranged second sliding plates correspondingly, a fixing base is installed at the other end of the top side of the bottom plate, a workpiece positioning plate used for fixing a connecting rod workpiece is installed on the fixing base, and a positioning groove is formed in the workpiece positioning plate. Inner hole positioning is adopted for the connecting rod workpiece, the maximum stroke amount is adjusted according to different hole diameters, namely the moving stroke amount of a stretching claw is adjusted, and the automatic clamping and positioning mechanism is suitable for machining of multiple types of connecting rod workpieces; an inner hole four-claw centering tensioning structure is adopted, and a centering pressing structure is additionally arranged at the small end of the connecting rod workpiece, so that the product positioning precision is greatly improved; and when a rotary table rotates at a high speed in the machining process, the positioning precision can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to an automatic clamping and positioning mechanism for multi-variety connecting rods. Background technique [0002] Connecting rods are used as auto parts, and they need to be fixed by clamping mechanism during processing. [0003] The existing clamping mechanism cannot realize the automatic clamping function and relies on the shape positioning, so the fixture needs to be replaced when changing production. The processing position is rotated. Contents of the invention [0004] The problem to be solved by the present invention is to provide an automatic clamping and positioning mechanism for connecting rods suitable for various varieties, which solves the problem that the existing clamping mechanism cannot realize the automatic clamping function, and the positioning depends on the shape, so the fixture needs to be replaced when the production is changed. Positioning,...
