AI Technical Summary

Technical Problem

Traditional positioning methods cannot meet the positioning requirements of blanks of different sizes and specifications, requiring frequent adjustments or replacements of positioning elements. Furthermore, rigid positioning structures are prone to causing damage to the surface of the blanks, affecting processing quality.

Method used

Adopting an adaptive positioning structure, combined with three-way hydraulic positioning, elastic buffer and adjustable base, the hydraulic push rod drives the moving plate and roller to achieve adaptive fitting of irregular blanks, and the elastic buffer and rubber layer reduce surface damage.

Benefits of technology

It enables rapid form changeover for blanks of different diameters, improves positioning accuracy and equipment utilization, reduces surface damage rate of blanks, and improves processing quality.

Abstract

This utility model belongs to the field of automotive gear forging blank positioning technology, and discloses an adaptive precision positioning structure for automotive gear forging blanks. It includes a frame with a base mounted at the bottom; a positioning plate mounted on the frame, with equidistantly spaced limiting grooves arranged in a circular array; and an adaptive positioning mechanism comprising three sets of radial positioning structures symmetrically distributed at 120°. Each radial positioning structure includes a hydraulic push rod, with a movable plate mounted on the piston end of the hydraulic push rod. The movable plate is slidably mounted within the limiting grooves, and an elastic buffer is mounted on the inner side of the movable plate. An arc-shaped frame is mounted on the elastic buffer, and rollers arranged equidistantly in an arc shape are mounted within the arc-shaped frame. Through the combined and coordinated use of three-way hydraulic positioning, elastic buffering, and an adjustable base, rapid blank changing with different diameters can be achieved, improving equipment utilization and solving the size limitations of traditional fixed pins.
