Diameter-adjustable barrel machining auxiliary tool

Abstract

The invention discloses a diameter-adjustable barrel machining auxiliary tool. The diameter-adjustable barrel machining auxiliary tool comprises a tool main body and a telescopic cylinder set. The tool main body comprises a main barrel and protruding rings symmetrically arranged at two ends of the main barrel. The outer side face of each protruding ring is connected with a guide ring. The outer side face of each guide ring is rotationally connected with a reducing control ring. The reducing control rings, the protruding rings, the guide rings and the main barrel are coaxially arranged. The telescopic cylinder set comprises a left telescopic cylinder set body and a right telescopic cylinder set body which are connected to the main barrel. The left telescopic cylinder set body is used for controlling the reducing control ring at one end to rotate, and the right telescopic cylinder set body is used for controlling the reducing control ring at the other end to rotate. At least three reducing rod sets are evenly distributed between the reducing control ring at each end and the corresponding protruding ring. The first ends of the reducing rod sets are connected with the reducing controlrings, the second ends of the reducing rod sets are hinged to the outer side faces of the protruding rings, and the side faces of the reducing rod sets are used for clamping workpieces penetrating through the main barrel. According to the tool, the reducing control rings rotate to drive the reducing rod sets to rotate, and barrels with different diameters are clamped.

Description

technical field [0001] The invention relates to the technical field of automatic processing, in particular to an auxiliary tooling for processing a diameter-adjustable cylinder. Background technique [0002] In the processing and welding process of large cylinder parts, it is often necessary to rotate or dock the cylinder, and the cylinder is usually installed in the support tooling. When processing cylinders of various diameters, due to the lack of versatility of the auxiliary tooling, one set of tooling corresponds to one type of cylinder, the replacement process is complicated, the manufacturing cost is high, and the degree of automation is low. A diameter-adjustable cylinder processing auxiliary tooling designed by Beijing University of Technology, patent number (ZL201410331644.9), which uses eight motor-driven jacks to control the movement of eight variable-diameter blocks respectively, and needs to control the synchronous coordination of four motors at each end Action...
