Abstract

The utility model discloses a specialized tool is cleared up fast to collars cap internal screw thread, including M16 hob tap, collars cap clamp bolt and rotatory hand wheel, collars cap clamp bolt's lower extreme is connected in M16 hob tap upper end, and rotatory hand wheel connection is in collars cap clamp bolt's upper end. This specialized tool adopts wheeled extra long screw tap structure, compresses tightly the screw to the collars cap and returns the tooth to swiftly remove clamp bolt on the collars cap effectively, reaching and easily swiftly clearing up, repair the interior tooth of collars cap corrosion, improve collars cap clamp bolt assembly efficiency.

Description

A kind of quick cleaning specific purpose tool of collars cap internal thread
Technical field
The utility model belongs to field of metallurgy, specifically a kind of quick cleaning specific purpose tool of high speed wire rod mill collars cap internal thread.
Background technology
High-speed wire factory mm finishing mill unit collars cap, 10 M16 hold-down bolts act on tapered sleeve by the manipulation pneumatic impact spanner that operating personnel can be made light, make tapered sleeve spreading, thus ensure that collars is in place and do not loosen.
In real work, on the collars cap disassembled often there is stuck phenomenon in hold-down bolt.Cause bolt cannot turn: caused by (1) bolt hole Nei Yatai is dirty.(2) in bolt hole, tooth or bolt tooth damage.The bolt that the first situation causes is stuck very general, and this tapered sleeve cannot guarantee that next time can dismantle smoothly after reaching the standard grade, and must carry out back tooth process.
Because regular tap length is only about 65mm, and the exposed part of 10 M16 hold-down bolts adds uppercap body thread height generally more than 100mm, want the corrosion on cap body had the thread of foreign material all to return tooth in the height direction cannot accomplish (interfering seriously with time tooth depth down screw tap drift holder and other bolt extensions), only have other bolts all to remove and just can carry out, very time and effort consuming.
Summary of the invention
For above prior art Problems existing point, the purpose of this utility model is to provide a kind of quick cleaning specific purpose tool of collars cap internal thread, this specific purpose tool adopts wheeled lengthening screw tap structure, compresses screw and carries out back tooth, thus remove hold-down bolt on collars cap effective and rapidly to collars cap.
The purpose of this utility model is achieved through the following technical solutions:
A kind of quick cleaning specific purpose tool of collars cap internal thread, it is characterized in that: this specific purpose tool comprises M16 die hob, collars cap hold-down bolt and rotation hand wheel, the lower end of collars cap hold-down bolt is connected to M16 die hob upper end, and rotation hand wheel is connected to the upper end of collars cap hold-down bolt.
In the utility model, the lower end of collars cap hold-down bolt is welded on M16 die hob upper end.The centre of rotation hand wheel is welded on the upper end of collars cap hold-down bolt.
M16 die hob upper end square head and collars cap hold-down bolt lower end major part are carried out straight line welding by the utility model, and then, then hold-down bolt upper end square head is welded with rotation hand wheel, wheeled like this lengthening screw tap just completes.With it, tooth in the corrosion of collars cap is carried out clearing up, repairing, improve the efficiency of assembling of hold-down bolt.
The utility model has been made into a kind of wheeled lengthening screw tap, aims at collars cap and compresses screw, screw tap can be screwed in like a cork collars cap bolt bore, rotates handwheel and tooth in screw is fast cleared up.
The utility model has the advantages that: owing to having welded handwheel on lengthening screw tap, can easily, quickly tooth in the corrosion of collars cap carried out clearing up, repairing, improve the efficiency of assembling of hold-down bolt.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is using state schematic diagram of the present utility model.
Detailed description of the invention
A quick cleaning specific purpose tool for collars cap internal thread, this specific purpose tool comprises M16 die hob 1, collars cap hold-down bolt 2 and rotation hand wheel 3, M16 die hob and is used for clearing up tooth in the corrosion of collars cap, repairing.M16 die hob upper end square head and collars cap hold-down bolt lower end major part carry out straight line welding, and collars cap hold-down bolt plays and lengthens the effect of M16 die hob.The centre of rotation hand wheel is welded on the upper end of collars cap hold-down bolt.
The concrete making step of the utility model is as follows: M16 die hob square head and collars cap hold-down bolt major part are carried out straight line welding, and then, then hold-down bolt square head is welded with rotation hand wheel, wheeled like this lengthening screw tap just completes.With it, tooth in the corrosion of collars cap is carried out clearing up, repairing, improve the efficiency of assembling of hold-down bolt.
The utility model uses very easy and convenient, saves a large amount of working times, makes collars cap obtain good maintenance.
