Automatic alignment type inner hexagonal bolt spanner

Abstract

The invention discloses an automatic alignment type inner hexagonal bolt assembly and disassembly spanner, and aims to provide an inner hexagonal spanner for automatic assembly with a function of rapidly realizing automatic alignment in automatic inner hexagonal bolt assembling and adjusting process. The automatic alignment type inner hexagonal bolt assembly and disassembly spanner is mainly composed of a ball head inner hexagonal rod, a fixing nut, a guide spring, a hexagonal guide torsion transmission sleeve and a magnetic block. In the case of the ball head inner hexagonal rod, a ball headis divided into six equal portions, so that the ball head is conveniently matched with the inner hexagonal surface of the inner hexagonal bolt, in the case of the ball head inner hexagonal rod, the end portion is provided with a protruding threaded stud so that the guide spring can be fixed on the ball head inner hexagonal rod through the fixing nut; one end of the guide spring is fixed on the protruding stud of the ball head inner hexagonal rod, the other end of the guide spring penetrates into the hexagonal guide torsion transmission sleeve so that assembly, disassembly and replacement can be facilitated, the upper end of the ball head inner hexagonal rod can penetrate into the six-face guide torsion transmission sleeve after pressing down the guide spring, and the torque is transmittedthrough six-face edge fitting; in the case of the six-face guide torsion transmission sleeve, a magnet is fixed on the upper portion so that the inner hexagonal bolt can be attracted, and thus assembly and disassembly are facilitated; and in the case of the inner hexagonal bolt spanner, the structure is simple, the alignment effect is good, the efficiency is high, in the continuous use process ofautomatic assembly, the automatic alignment between the spanner and an inner hexagonal groove of the inner hexagonal bolt can be smoothly realized, and the surface of a product can be effectively protected against being scratched.

Description

technical field [0001] The invention relates to the field of an automatic assembly and adjustment tool for an inner hexagonal bolt of a punch head of a multi-point forming stamping die, in particular to an automatic centering type inner hexagonal bolt wrench. Background technique [0002] Hexagon wrench is a common tool in mechanical operation, used for disassembly and assembly of hexagon socket bolts; when the current hexagon wrench aligns the inner hexagon groove at the end of the hexagon bolt, it cannot be guaranteed to be in place at one time, and sometimes it needs to be rotated repeatedly Only by shifting can it be centered, resulting in a waste of efficiency; especially when automatically assembling and adjusting the hexagon socket head bolts, inaccurate alignment will cause damage to the hexagon socket grooves at the ends of the hexagon socket head bolts, and seriously scratch the surface of the product. [0003] Now, in the multi-point forming die stamping industry,...
