Large shaft tube stepping mechanism

Abstract

The invention discloses a large shaft tube stepping mechanism. The large shaft tube stepping mechanism comprises a fixed rack, wherein a plurality of uniformly distributed supporting legs are arrangedat the bottom end of the fixed rack; two groups of guide plates are symmetrically arranged at the top end of the fixed rack in a front-back manner; guide grooves are obliquely formed in the guide plates; four supporting rods are symmetrically arranged at four corners of the top end of the fixed rack; sliding rails are arranged on the inner sides of the supporting rods; a vertical lifting frame isconnected between the sliding rails in a sliding manner; roller groups matched with the sliding rails are arranged at the left end and the right end of the vertical lifting frame; and vertical lifting frame connecting ribs are symmetrically arranged at the bottom end of the vertical lifting frame in a front-back manner. The internal mechanism of the large shaft tube stepping mechanism adopts a hydraulic system as power, is high in bearing capacity and stable in mechanism performance, can meet the requirement of a large shaft tube, and is accurate in control, simple in mechanism, easy to operate and easy to maintain; the application range of the shaft tube is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of stepping and feeding mechanisms, in particular to a large shaft tube stepping mechanism. Background technique [0002] During the production and processing of large-scale shaft tubes, a stepping transfer mechanism is required for displacement transfer. At present, similar products in the market generally use cam eccentric structures, connecting rod mechanisms or cylinder version stepping mechanisms, but due to structural limitations, They are generally suitable for small shaft tubes below φ100mm and shaft tubes weighing no more than 50kg, which cannot meet the needs of large shaft tubes, and the stepping distance is short, and it takes multiple feedings to complete the entire feeding process, and in the stepping transfer process There will be a lot of impact sound, and the noise pollution of the equipment is relatively serious. Contents of the invention [0003] The purpose of the present invention is ...
