Description

A kind of steel pipe welding connector tools for cleaning rust

Technical field

A kind of device to derust in advance for steel-pipe welding is the utility model is related to, is removed more particularly to a kind of steel pipe welding connector Rust instrument.

Background technology

It is existing since end rust is often required to carry out derusting operation to steel pipe during butt welding in steel pipe uses or produces There is the sanding apparatus area coverage small, it is impossible to which port is inside and outside to polish at the same time, and surface is polished uneven, and efficiency is low, this still needs Solved in technology.

Utility model content

To solve the above-mentioned problems, the utility model provides a kind of steel pipe welding connector tools for cleaning rust.

The technical solution adopted in the utility model is a kind of steel pipe welding connector tools for cleaning rust, it is characterised in that including cylinder, Pressure ring, outer brush and interior brush, pressure ring are internally provided with the boss of the end face of an annular backwards, and boss passes through forward equipped with circumferentially distributed Six to eight gap worn, the last gap both sides of raised head face are equipped with axis nest, and pressure ring rear end is connected with cylinder front end, before cylinder End, which is equipped with, is pressed in presenting a theatrical performance as the last item on a programme on axis nest, and the closure of cylinder rear end is connected with drilling rod；Outer brush stretches into circle equipped with corresponding with gap quantity The circumferentially distributed outer brush board bar of cylinder, each outer brush board bar middle part are respectively connected with the support arm stretched out on the outside of phase, and each support arm is respectively connected with The axostylus axostyle of two side axle nest of embedded gap, outer brush board bar inner face polishing bristle；Interior brush, which is equipped with, is fixed by screws in cylinder interior envelope The circular egative film coaxial with cylinder blocked, is connected with intilted interior brush board bar, interior brush board bar around egative film by shrapnel Outside is equipped with polishing bristle.

Further, the outer brush board sliver transvers section is arc-shaped.

Further, it is characterised in that the polishing bristle is steel wire bristle or fiber bristles.

Further, brush board bar equal length outside the support arm both sides.

Further, the support arm is less than away from one end length outside cylinder away from one end length in outer brush board bar cylinder.

Further, the outer brush board bar is inner is located at interior brush stave lengths half position with inner.

Drilling rod is connected with drilling machine when the utility model is used, outer brush board bar can be swung around axostylus axostyle, and outer brush board bar front end can Abduction, enlarged openings size, is inserted into easy to steel pipe, is ajusted after insertion by the outer brush board bar revolution of elasticity, interior brush head front end is drawn close Facilitate insertion into steel pipe, start drilling machine and drive cylinder rotation, outer brush board bar is to carrying out circumferential polishing, interior brush board outside steel tube head Bar under the action of the centrifugal force implement to carry out steel tube head inner face circumferential polishing outside free end by pendulum, polishes quick comprehensively thoughtful.

Fig. 2 is the utility model embodiment schematic cross-sectional view.

Reference numeral:1 cylinder；2 pressure rings；3 boss；4 gap；5 axis nests；6 present a theatrical performance as the last item on a programme；7 closure；8 drilling rods；9 outer brush board bars；10 Support arm；11 axostylus axostyles；12 screws；13 egative films；14 shrapnels；Brush board bar in 15.

Embodiment

As shown in Figure 1, 2, which is equipped with cylinder 1, pressure ring 2, outer brush to the utility model embodiment With interior brush, pressure ring is internally provided with the end face boss 3 backwards of an annular, boss be equipped with circumferentially distributed perforative forward six to Eight gap 4, the last gap both sides of raised head face are equipped with axis nest 5, and pressure ring rear end is connected with cylinder front end, and cylinder front end is equipped with It is pressed on axis nest and presents a theatrical performance as the last item on a programme 6, cylinder rear end closure 7 is connected with drilling rod 8；Outer brush is equipped with stretch into cylinder corresponding with gap quantity Circumferentially distributed outer brush board bar 9, each outer brush board bar middle part are respectively connected with the support arm 10 stretched out on the outside of phase, and each support arm is respectively connected with embedding Entering the axostylus axostyle 11 of two side axle nest of gap, outer brush board bar inner face is polished bristle, and polishing bristle is steel wire bristle or fiber bristles, as long as It is able to can be used beneficial to decontamination of derusting；Interior brush is equipped with the circle coaxial with cylinder being fixed on by screw 12 in cylinder interior closure Shape egative film 13, is connected with intilted interior brush board bar 15 by shrapnel 14 around egative film, polishing is equipped with outside interior brush board bar Bristle.

During implementation, outer brush board sliver transvers section can be arc-shaped, with goodness of fit higher outside steel pipe；Brush board bar is grown outside support arm both sides Spend it is equal, or support arm away from one end length in outer brush board bar cylinder be less than away from one end length outside cylinder, outer end amplitude of fluctuation is big, is easy to Steel pipe enters；Outer brush board bar is inner to be located at interior brush stave lengths half position with inner, and inside and outside bristle is at the end of steel tube head Cross at face and implement satin face polishing, polishing is more comprehensively.

It is only in summary the utility model preferred embodiment, all equivalent modification done according to the application and the prior art add Add and be accordingly to be regarded as the utility model technology category.
