Tooling for machining grooves

Abstract

The invention provides a fixture for machining a groove. The fixture comprises a bottom device, an operating panel, fixing units and positioning units matched with the fixing units; each positioning unit passes through a positioning groove and is in close contact with the bottom device, and the bottom of the operating panel is connected with an inclined surface of the bottom device; two second movable tracks parallel to each other are arranged on an upper portion of the operating panel; a plurality of fixing units are connected to the second movable tracks in a sliding manner; an inclined surface is formed on an upper portion of the bottom device, and an included angle between the inclined surface and a horizontal direction is matched with an angle of a groove to be machined; further, parallel positioning holes are formed in two end portions, in the horizontal direction, of the upper portion of the bottom device. the fixing fixture of the present invention is simple in structure and small in occupied space; a fixed length and a fixed height of a fixing rod on the fixture also can be adjusted, such that the fixture is adaptive to groove machining operations of square steel tubes of different specifications; and the fixture is high in universality and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a fixed tool for processing grooves of square steel pipes. Background technique [0002] The square steel pipe is the main profile of the container. When the opposite steel pipe is welded, in order to ensure the strength of the welding, it is necessary to open a groove at the end of the square steel pipe. The traditional method of processing grooves is mainly the processing method of manual flame cutting. Since manual flame cutting can only be processed on a single piece, the other steel pipe needs to be fixed and positioned before each processing. During the cutting process, the angle of the cutting bevel is manually adjusted, and the processing efficiency is low; at the same time, the bevel angle of the manual fixed operation cutting is consistent. The performance is poor, and it is difficult to control the groove angle, which affects the subsequent welding ope...

AI Technical Summary

Problems solved by technology

[0003] In view of this, the present invention aims to propose a fixed tooling for processing grooves of square steel pipes, so as to solve the problems of low processing efficiency and poor consistency of groove angles by manually adjusting the processing angle after manual flame cutting of the opposite steel pipe.
