Abstract

A novel wire-carrying sleeve for a stud bolt is characterized in that an assembly hole is formed in a handle body; a ring-shaped groove is formed at the front end of the handle body; a through hole is formed on the ring-shaped groove; a round hole is formed at the rear end of the handle body; the handle body is connected with a sleeve body through pin shafts; the pin shafts are sealed with an external seal ring; an inner sleeve is placed in the sleeve body; and a roller is placed in the inner sleeve. The novel wire-carrying sleeve for the stud bolt has the benefits as follows: no damage is caused to the surface of a tightened bolt; the wire-carrying sleeve has the characteristics of reliability and high efficiency; and particularly, the wire-carrying sleeve has no influence on tightening precision when withdrawn, and can give full play to the advantages of low noise, high frequency and high precision when a tightening machine is adopted for assembly.

Description

Novel year silk braid tube of stud

Technical field

The utility model relates to a year silk braid tube field, specifically is meant novel year silk braid tube of stud.

Background technology

Production lines such as present most of automobile, diesel engine are assembled stud and are generally adopted pneumtic impact wrench, not only noise is big, efficient is low, working strength is high and tighten low precision, owing to be not the supporting socket wrench specially adapted for it of tightening machine, can't adopt tightening machine to carry out assembling operation, can not bring into play tightening machine assembling low noise, high efficiency, high-precision advantage.

Summary of the invention

In view of the defective that prior art exists, the purpose of this utility model provides a kind of low noise, high-frequency, novel year silk braid tube of high-precision stud.

For achieving the above object, the technical solution that the utility model adopted mainly is made up of handle body, pilot hole, annular groove, through hole, circular hole, bearing pin, sleeve body, sealing ring, interior cover, roller; It is characterized in that: in the handle body pilot hole is arranged, handle body front end has an annular groove, and annular groove is provided with a through hole, handle body rear end is provided with a circular hole, and the handle body is connected by bearing pin with sleeve body, and sealing ring is sealed in outside the bearing pin, be positioned over the interior cover in the sleeve body, in overlapping in roller is positioned over.

The inner surface of described sleeve body is a helical form.

The beneficial effects of the utility model are: connect reliably being tightened bolt surface not damaged, having, the characteristics that efficient is high do not influence when especially withdrawing from and tighten precision, can give full play to tightening machine assembling low noise, high-frequency, high-precision advantage.

Description of drawings

Fig. 1 is overall appearance figure of the present utility model;

Fig. 2 is a profile of the present utility model.

The specific embodiment

Fig. 1, Fig. 2 Reference numeral are as follows: handle body 1, pilot hole 2, annular groove 3, through hole 4, circular hole 5, bearing pin 6, sleeve body 7, sealing ring 8, interior cover 9, roller 10.

In the structure diagram of Fig. 1, novel year silk braid tube of stud shown in Figure 2, its primary structure comprises: pilot hole 2 is arranged in the handle body 1, handle body 1 front end has an annular groove 3, annular groove 3 is provided with a through hole 4, handle body 1 rear end is provided with a circular hole 5, and handle body 1 is connected by bearing pin 6 with sleeve body 7, and sealing ring 8 is sealed in outside the bearing pin 6, be positioned over the interior cover 9 in the sleeve body 7, overlap in 9 in roller 10 is positioned over.

With the pilot hole 2 of novel year silk braid tube of stud by handle body 1 front end with tighten axle and be connected, pass through hole on the annular groove 3 with a bearing pin 6, with sleeve body 7 with tighten axle and fix, the front end of stud is screwed into workpiece two or three to be buckled, the rear end and the bolt of sleeve body 7 are aligned, start tightening machine, novel year silk braid tube of stud is rotated under the drive of tightening axle, bolt rear end threaded portion enters in the circular hole 5 of handle body 1 rear end, the end face of circular hole 5 end face puller bolts, tighten axle and continue rotation, roller 10 rotates displacement in interior cover 9, when roller 10 can't rotate, the light face of fishbolt, bolt and novel year silk braid tube of stud were integral and rotated this moment, after bolt is screwed into workpiece, tightened the axle counter-rotating, roller 10 resets in interior cover 9, decontrol bolt, tighten 7 counter-rotatings of axle drive sleeve body and withdraw from, tighten end-of-job.

Claims

1. novel year silk braid tube of stud is characterized in that: be made up of handle body, pilot hole, annular groove, through hole, circular hole, bearing pin, sleeve body, sealing ring, interior cover, roller; In the handle body pilot hole is arranged, handle body front end has an annular groove, and annular groove is provided with a through hole, and handle body rear end is provided with a circular hole, and the handle body is connected by bearing pin with sleeve body, and sealing ring is sealed in outside the bearing pin, is positioned over the interior cover in the sleeve body, in overlapping in roller is positioned over.
