Three-point welding placing support positioning structure

Abstract

The invention discloses a three-point welding placing support positioning structure. The three-point welding placing support positioning structure comprises a positioning base table with a placement groove formed in the middle, a base layer is arranged on the positioning base table, magnets are arranged in the base layer, and weldment supporting assemblies are arranged at the top of the base layer. Sliding friction between weldment supports and the positioning base table is converted into rolling friction through column type roller parts, the moving capacity of the weldment supports in positioning grooves is effectively improved in the state that the magnets strongly attract the weldment supports, and the weldment supports can still be flexibly adjusted after being placed in the positioning grooves; the weldment supports accurately corresponds to welding points of a motor shell in the placement groove; and pushing blocks enable the two ends of the column type roller parts to be bent inwards after the positions of the weldment supports are adjusted by the column type roller parts, so that the rolling capacity is lost, rolling friction between the weldment supports and the positioning base table is converted into sliding friction again, and therefore the stable limiting of the welding supports after position adjustment is completed.

Description

technical field [0001] The invention relates to the technical field of micro-motor casing bracket welding manufacturing, in particular to a three-point welding bracket positioning structure. Background technique [0002] As a basic manufacturing connection process, welding is widely used in various fields related to mechanical manufacturing. The special knuckle-shaped structure of the motor bracket is expensive to directly adopt CNC machining, and it is difficult to meet the performance requirements for casting molding, so welding molding is usually used. Due to the rapid development of welding technology and the improvement of product quality requirements, the positioning accuracy requirements for the welding joints of the motor bracket are also getting higher and higher. Especially in the installation and positioning of the EMU, the position requires high precision, and a little error of the welding joint may directly affect the stability of the motor operation, and the n...
