Adhesion type spherical face point closing block

Abstract

The invention discloses an adhesion type spherical face point closing block. Closing block bodies (2) and closing block pressing heads (4) are included. The adhesion type spherical face point closingblock is characterized in that a groove body (3) is arranged in the front end of each closing block body (2); the spherical closing block pressing head (4) is installed in each groove body (3); the three closing block bodies (2) are annularly arrayed and distributed at 120 degrees, and a closing cavity is defined by the closing block pressing heads (4) on the three closing block bodies (2); each closing block body (2) is provided with an installing hole (1) and a positioning step (5); and the closing block bodies (2) and the closing block pressing heads (4) adhere to each other through organicglue. The adhesion type spherical face point closing block is simple in structure, accurate and practical, good in consistency, stable and reliable, and suitable for being used and popularized in nutspherical face point closing.

Description

technical field [0001] The invention belongs to the technical field of nut closing devices, and in particular relates to an adhesive spherical point closing block. Background technique [0002] In order to improve the tightening effect and stability of nuts, it is a very common operation to close the nuts. In the nut closing process, the lock nut closing block is a widely used processing technology equipment. The closing processing is generally to squeeze the outer wall of the nut closing structure through the surface tooling, so that the thread is deformed to a certain extent to generate an assembly locking torque. In the prior art, the form of point closing is mostly flat point extrusion on the outer wall of the nut closing structure, and flat extrusion usually causes a large change in the thread profile angle, which is likely to cause the metal flow line in the deformed area to break, which may affect the assembly performance of the parts. It causes adverse effects, whic...

AI Technical Summary

Problems solved by technology

In the prior art, the form of point closing is mostly flat point extrusion on the outer wall of the nut closing structure, and flat extrusion usually causes a large change in the thread profile angle, which is likely to cause breakage of the metal streamline in the deformed area, which may affect the assembly performance of the parts. It caused adverse effects, which greatly affected the quality and stability of the nut closure, resulting in low processing accuracy and poor consistency, which could no longer meet the existing processing requirements.
