Fixing device for bolt assembly automatic production and working method thereof

Abstract

The invention discloses a fixing device for bolt assembly automatic production and a working method thereof, and relates to the technical field of fixing devices, the fixing device specifically comprises a bottom plate and a base, threaded holes are formed in the bottom of the base, fixing bolts are arranged on the lower surface of the bottom plate, and the base is located on the upper surface of the bottom plate; the top of the fixing bolt penetrates through the bottom plate and extends to the top of the bottom plate to be in threaded connection with the inner wall of the threaded hole, a through groove A is formed in the lower surface of the bottom plate, a containing groove is formed in the position, corresponding to the through groove A, of the lower surface of the base, and a groove is formed in the position, corresponding to the containing groove, of the upper surface of the base. By arranging a rotating structure, an extrusion block structure and a clamping block, the effect of clamping and fixing bolts with different calibers is achieved, and the problems are solved that one clamping device can only measure the torsion strength corresponding to one bolt, other bolts with different calibers are difficult to test in use, the cost is increased due to the one-to-one mode, and the practicability is poor.

Description

technical field [0001] The invention relates to a fixing device, in particular to a fixing device for automatic production of bolt assembly and a working method thereof. Background technique [0002] A type of fastener consisting of a head and a screw (cylindrical body with external threads), which needs to be matched with a nut for fastening and connecting two parts with through holes, mechanical parts, and nuts There are many types of bolt tests for cylindrical threaded fasteners. In order to test whether the bolts are qualified, the torsional strength test of the bolts is an essential item. By fixing the bolts and then rotating the bolts with a test tool, Until the test bolt is twisted off, the strength of the torsional force can be displayed on the test tool at this time, so as to test whether the torsional force reaches the standard. [0003] Some existing bolt testing devices are generally only suitable for one kind of bolt, and one clamping device can only measure th...

AI Technical Summary

Problems solved by technology

[0003] Some existing bolt testing devices are generally only suitable for one kind of bolt, and one clamping device can only measure the torsional strength corresponding to one kind of bolt. It is difficult to test other bolts with different calibers during use. The one-to-one method not only increases the cost, but also makes the practicality poor, which makes daily use more troublesome
