Fixtures for fixing cylinders and columns

Abstract

The invention discloses a tool set for fixing cylinders and columns, which comprises a base (1) and at least two cylinders (4), wherein the base (1) is provided with a ring channel (2) and at least one straight channel (3); the inner end of the straight channel (3) is communicated with the ring channel (2); both sides of each straight channel (3) are respectively provided with a cutter feed chute (5); the inner end of each cutter feed chute (5) is a tip (5.1); the tip (5.1) of each cutter feed chute (5) is positioned at the communication part of the ring channel (2) and the straight channel (3); each cutter feed chute (5) is matched with a cutter (6) in an inside slip mode; the back end of each cutter (6) is fixed with a piston rod (4.1) of one cylinder (4); and each straight channel (3) is provided with a device for abutting against the column. The tool set for fixing cylinders and columns has the advantages of high speed, high efficiency and firm fixation, and can not damage the workpiece in a large area.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a tool for fixing a cylinder and a column. Background technique [0002] In the field of machinery manufacturing, especially in the auto parts industry, people often need to connect and fix cylindrical workpieces, namely cylindrical parts, and cylindrical (cylindrical, square cylindrical, hexagonal cylindrical) workpieces, namely column parts. Said, a mounting hole is provided on the circumferential surface of the cylinder, the cross section of the mounting hole is cylindrical, square, or hexagonal corresponding to the cross section of the column, and the column is passed through the mounting hole and the circle The barrel is fixed. [0003] There are two connection and fixing methods in the prior art: one is to make the column fit in the installation hole of the cylinder, and then use spot welding to weld and fix the column and the wall of the installation hole. The welding points are ge...

Problems solved by technology

This connection and fixing method requires manual spot welding. Manual operation is slow, inefficient, and the welding accuracy is low, the effect is poor, and it is not firm. More importantly, it often causes large-area welding damage to the workpiece due to operational errors.

[0004] Another connection and fixing method is to fit the column piece in the mounting hole of the cylindrical piece with interference fit, and then braze. Since the column piece and the cylindrical piece are interference fit, the gap between the column piece and the cylindrical piece installation hole If the gap is too small, the welding fluid cannot flow in, so the strength of the final connected and fixed workpiece cannot meet the requirements and is not firm
