Hydraulic oil cylinder body assembling and welding tool with positioning mechanism

Abstract

The invention relates to the technical field of assembling and welding tools, in particular to a hydraulic oil cylinder body assembling and welding tool with a positioning mechanism. The tool comprises a tool table and a tool plate arranged on the top of the tool table, a cavity is formed between the tool table and the tool plate, the positioning mechanism is arranged on the top of the tool plate,the positioning mechanism comprises a supporting frame, a fixed base and a movable base, and the movable base comprises a movable supporting plate; and two movable supporting blocks are symmetricallydistributed in the middle of the top of the movable supporting plate, threaded holes are formed in the two sides of each movable supporting block, and positioning bolts are arranged in the threaded holes. According to the tool, a transverse graduated scale is arranged, and sliding blocks cooperate with a sliding groove, so that the movable base transversely moves, the purpose of precisely adjusting the distance between the front edge of the movable supporting plate and the front edge of a fixed supporting plate is achieved, and errors caused by manual judgment are reduced.

Description

technical field [0001] The invention relates to the technical field of assembly and welding equipment, in particular to a hydraulic cylinder body assembly and welding equipment with a positioning mechanism. Background technique [0002] During welding, the workpiece needs to be positioned manually. The general positioning has six-point positioning, which means that the workpiece has six degrees of freedom in space, that is, the degree of freedom of movement along the three rectangular coordinate axes of x, y, and z and the degree of freedom around this axis. The rotational degrees of freedom of the three coordinate axes, therefore, to fully determine the position of the workpiece, these six degrees of freedom must be eliminated, and usually six support points (ie, positioning elements) are used to limit the six degrees of freedom of the workpiece, each of which The supporting point restricts a corresponding degree of freedom. Considering that the cylinder block is a cylindri...

Problems solved by technology

[0002] During welding, the workpiece needs to be positioned manually. The general positioning has six-point positioning, which means that the workpiece has six degrees of freedom in space, that is, the degree of freedom of movement along the three rectangular coordinate axes of x, y, and z and the degree of freedom around this axis. The rotational degrees of freedom of the three coordinate axes, therefore, to fully determine the position of the workpiece, these six degrees of freedom must be eliminated, usually with six support points (ie, positioning elements) to limit the six degrees of freedom of the workpiece, each of which The support point restricts a corresponding degree of freedom. Considering that the cylinder body is a cylindrical structure and needs to be rotated during assembly welding, six-point positioning cannot meet the needs of assembly welding. Generally, positioning components are provided for five-point positioning.

[0003] However, when the cylinder block is placed, the adjustment distance between the positioning components is judged manually, and the numerical judgment cannot be realized, thereby reducing the positioning accuracy and increasing the positioning error
