Automatic overturn supporting device for crank shaft blank

Abstract

The invention relates to an automatic overturn supporting device for a crank shaft blank, which is provided with a base. Two connecting rod supporting plates and two spindle supporting plates are symmetrically mounted on the base; landing legs are vertically arranged at the bottom of the connecting rod supporting plates and the spindle supporting plates, and respectively fixed on the base through bolts; the spindle supporting plates are lower than the connecting rod supporting plates; and the supporting centers of the spindle supporting plates deviate from those of the connecting rod supporting plates. The connecting rod supporting plates are U-shaped iron plates, and U-shaped supporting surfaces are arranged on the upper parts of the connecting rod supporting plates; the spindle supporting plates are V-shaped iron plates; V-shaped supporting surfaces are arranged at the upper parts of the V-shaped iron plates; and a heighten shim plate is arranged under the spindle supporting plates. The supporting device is arranged on the turnover trolley on an automatic forging production line from a twisting-turn process to a finishing process, so that a six-cylinder crankshaft blank can rotate automatically around the axle center line thereof with 60 degrees to replace the overturn of a manipulator, which further reduces the complexity of the manipulator, prolongs the service life, shortens the production speed and improves the labor productivity of the enterprise.

Description

technical field [0001] The invention relates to a supporting device, in particular to an automatic flip supporting device for a crankshaft blank. It is used on the turnover car of the automatic forging production line from the twisting process to the finishing process to automatically turn the six-cylinder crankshaft blank 60° around its axis. Background technique [0002] At present, most of the six-cylinder forged steel automobile crankshaft blanks with plane split molds in China, in the process of forging and twisting, take the second and fifth connecting rods as the horizontal reference, and the first and sixth connecting rods and the third and fourth connecting rods are respectively along the Clockwise and counterclockwise twisted by 60°, resulting in a phase angle of 120°. In China, especially the automatic forging production line, the turnover of the blank from the twisting process to the finishing process is generally completed through the cooperation of two manipul...

Problems solved by technology

In this way, the mechanical complexity of the manipulator is increased, the service life is reduced and the production cycle is prolonged.

[0003] So far, there is no literature report on the crankshaft blank automatic turning support device on the automatic forging production line
