180-degree overturning machine for small-height double-clamp integral rolling type large part

Abstract

A 180-degree overturning machine for a small-height double-clamp integral rolling type large part mainly comprises a base and an overturning machine body. Straight teeth are arranged on the circumferential surface of a rolling wheel stand, a pair of positioning calipers is arranged in a through hole of the rolling wheel stand, one end of a calipers moving oil cylinder is connected with the positioning calipers, the other end of the calipers moving oil cylinder is fixedly connected with the wheel stand, a clamping head end of the pair of positioning calipers is of a V-shaped structure, the upper portion and the lower portion of the pair of positioning calipers are both provided with a pair of support lugs, moving clamping heads are hinged to the support lugs, the rear portions of the moving clamping heads are connected with one end of an overturning oil cylinder, the other end of the overturning oil cylinder is fixed on the pair of positioning calipers, the moving clamping heads are provided with clamping oil cylinders, the pair of positioning calipers at the back of the support lugs is provided with a sizing block moving oil cylinder, two ends of the sizing block moving oil cylinder are connected with sizing blocks respectively, the overturning machine body is placed in the base with the middle provided with an upper opening groove, an arc-shaped base roller table is arranged in the base, and a driving rotor of a driving device positioned on the roller table is provided with a driving gear corresponding to the straight teeth of the wheel stand. The 180-degree overturning machine is simple in structure and high in bearing capacity, clamps the part conveniently, and is safe and reliable.

Description

technical field [0001] The invention relates to a large-scale auxiliary mechanical equipment for heavy-duty machine manufacturing, in particular to the mechanical equipment used for 90-degree and 180-degree turning of large-scale heavy-duty parts when required by the process. Background technique [0002] In heavy equipment manufacturing, large heavy-duty parts with special working conditions such as extreme size and large tonnage need to be turned over many times during the machining process. At present, two cranes in the workshop are generally used to achieve 180-degree turning with the help of wire ropes. However, these large castings and forgings or parts have large dimensions, up to 6 meters, and a single weight ranging from 10 tons to 250 tons. Due to their large size and weight, large impacts will be generated due to inertia during the turning process. There are great hidden dangers in production safety. There have been accidents such as injury accidents and damage to...

AI Technical Summary

Problems solved by technology

Through comparative analysis, it is found that the turning machines disclosed above that can realize 180-degree turning have a common deficiency, that is, their structure or driving type cannot be better applied to turning machines for large and heavy-duty parts.
