Problems solved by technology

[0004] The technical problem solved by the present invention is to provide a threaded sleeve press-fitting tool, which overcomes the bottleneck and difficulty in the assembly process of threaded sleeve press-fitting, and solves the problem that there is no special press-fitting tool for the threaded sleeve press-fitting assembly process. The suggested assembly tools are likely to cause problems such as deformation of the internal thread, unstable assembly of the knurling of the steel sleeve, and deformation of the external thread.

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] see figure 2 , a threaded sleeve pressing tool of the present invention, the tool includes a threaded pressure head 1, a manual press 13; and also includes an installation wrench 12.

[0024] like Figure 4 As shown, it is the I-type structure of the threaded pressure head, that is, the first embodiment. The threaded sleeve pressure head 1 includes a screw 3, a pressing piece 4, a sleeve 5, a first pull rod 6, and a first support block 7; It is screwed into the threaded sleeve to protect the internal thread during press-fitting; the pressing piece 4 is used to press down the upper edge of the threaded sleeve during press-fitting; the sleeve 5 and the first tie rod 6 support the first A support block 7 acts; the first support block 7 is used to support the manual pressure pump structure.

[0025] The rear end of the screw 3 is connected to the first...

Abstract

The invention discloses a thread busing press fitting tool, and belongs to the technical field of assembly. The bottleneck difficulties in the assembly process of press fitting of a thread bushing areovercome, and the problems that no special press fitting tool exists in the assembly process of press fitting of the thread busing, while deformation of an internal thread, unsteady assembly of knurling of a steel bushing, deformation of an external thread and the like are prone to being generated by using a suggested assembly tool are solved. The thread bushing press fitting tool comprises a hand press and a thread bushing pressure head. Special thread bushing pressure heads are adopted according to different specifications of thread bushings, press fitting of the thread bushing is conductedby utilizing the convenient hand press or a handheld type pressure pump, the steel bushing press fitting pressure of the press fitting tool is even and steady, the internal thread of the thread bushing can be protected when a workpiece is pressed in, and the thread bushing cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of assembly, and relates to a tool for press-fitting a threaded sleeve. Background technique [0002] The threaded sleeve is made of a high-strength, high-precision steel material. It is a fastener that enhances the strength of the thread. It is generally used to be embedded in the box and can form a high-strength internal threaded hole. In the previous assembly process, since there was no special tool, the use of tools such as a copper hammer for press-fitting would easily destroy the threaded sleeve structure, thereby destroying the internal thread mechanism and affecting the tightening of parts. SUMMARY OF THE INVENTION [0003] (1) Technical problems to be solved [0004] The technical problem solved by the present invention is to provide a threaded sleeve press-fitting tool, which overcomes the bottleneck and difficulty of the assembling process of threaded sleeve press-fitting, and solves the proble...
