Projection welding screw chuck structure

Abstract

The invention relates to the technical field of a novel projection welding screw chuck structure, in particular to a structure that an annular chuck which is evenly distributed and divided into eightequal parts is provided, the annular chuck is internally provided with a step taper hole and can pass through a projection welding screw of a big flange plate, the outer diameter of the annular chuckis provided with two annular grooves capable of loading annular springs, and when the projection welding screw is delivered out from a middle hole, the chuck can have a large filed angle. Especially,the structural machinability that when the large flange plate of the projection welding screw is delivered out from the middle hole, the diameter of the projection welding screw is small, and the flange plate is large, so that the filed angles of conventional spring chucks cannot be opened is avoided. According to the novel projection welding screw chuck structure, through effective coordination with other structures, automatic welding of the projection welding screw is feasible. According to the main technical scheme and technical key points, when the projection welding screw of the big flange plate is delivered out from the internal middle hole, the projection welding screw chuck can have the large filed angle to ensure that the projection welding screw can pass through, and the filed angles of the conventional spring chucks cannot be opened is avoided.

Description

technical field [0001] The invention relates to the technical field of a new type of projection welding screw chuck structure, in particular, it is a ring chuck equipped with eight equal parts, and the projection welding screw can pass through a large flange inside, and the chuck can have a large size. A structure of the angle, which solves the problem that the diameter of the projection welding screw is small, the flange is large, and the opening angle of the chuck of the projection welding screw cannot be opened. Background technique [0002] The automatic connection of fasteners is the current technical trend. From manual connection to fully automatic connection, it has advantages in reducing personnel, reducing labor intensity, improving the operator's environment, and forming a stream of production lines. [0003] In the current design of metal structural parts of automobiles and home appliances, direct projection welding of metal parts or nuts and screws to another par...
