Description
Technical field
The utility model belongs to steel pipe processing technique field, more particularly to a kind of steel pipe inner wall grinding device.
Background technology
Stainless steel welded pipe can form weld seam when welding, weld seam is higher than surface, polishes, the weld seam processing letter of outer wall
Single, the weld grinding technique in welded tube is increasingly complex.Problem of the existing technology is：Since grinding device stretches into meeting in welded tube
It drops, along with the presence of weld seam so that grinding device can not accomplish that grinding head is uniformly bonded with inner wall in polishing, beat
Bistrique is squeezed by gravity and weld seam, and pipe inner bottom surface and the inner wall of weld seam offside can be made also to be polished, and is caused to lose circle in welded tube, also be added
The big loss of grinding head.
Utility model content
Problem to be solved in the utility model is, overcomes the deficiencies of the prior art and provide one kind and avoids inner wall of welded pipe
It is polished, reduces the steel pipe inner wall grinding device of grinding head abrasion.
The utility model solves its technical problem and following technical scheme is taken to realize：
A kind of steel pipe inner wall grinding device, including pedestal, fixed frame, motor rack and polishing bar, motor rack setting
On pedestal, the front end of pedestal is set there are one welded tube bracket, and motor rack is interior to be equipped with driving motor, driving motor and bar phase of polishing
Even, polishing bar front end is equipped with grinding head, is arranged at intervals with by grinding head to motor rack side multiple with throwing that is being bonded inside pipeline
Halo is provided with liquid spout between adjacent polishing wheel；The both sides of grinding head are respectively equipped with forward and backward auxiliary positioning mechanism, auxiliary
Detent mechanism is helped to include 3 to 6 positioning columns being vertically set on polishing bar, universal ball wheel is equipped at the top of positioning column.
The preceding auxiliary positioning mechanism is arranged on a free bar being connected with polishing bar, and free bar leads to polishing bar
Bearing is crossed to be connected.
The front end of the free bar is inserted into a support rail, and support rail is vertically located at fixed frame side.
Welded tube fixed jaw is additionally provided on the fixed frame.
The side of the auxiliary positioning mechanism is equipped with rounded tabs, and water mist can be as possible retained in grinding head surrounding,
Reduce water consumption.
Elastic support is equipped between the universal ball wheel and positioning column.
The utility model has significant advantages and beneficial effects compared with prior art：Grinding and buffing can simultaneously into
Row, auxiliary positioning mechanism can help grinding head to be on the center line of pipeline always, and grinding head is avoided to be squeezed by the weld seam of protrusion
It presses and unnecessary abrasion is caused to inner wall of the pipe, fixed frame can provide support for the front end for bar of polishing, and prevent it by gravity
Tenesmus is influenced, fixed frame and welded tube bracket engagement can keep welded tube horizontal stable.
Description of the drawings
Fig. 1 is the vertical view of the utility model.
Specific embodiment
Below in conjunction with attached drawing and preferred embodiment, to according to specific embodiment provided by the utility model, structure, feature
And its effect, it is described in detail as after.
A kind of steel pipe inner wall grinding device as shown in Figure 1, including pedestal 1, fixed frame 2, motor rack 3 and polishing bar 4, institute
The motor rack 3 stated is arranged on pedestal 1, and the front end of pedestal is set there are one welded tube bracket 5, and motor rack is interior to be equipped with driving motor, drives
Dynamic motor is connected with polishing bar 4, and polishing bar front end is equipped with grinding head 6, is arranged at intervals with by grinding head 6 to motor rack side multiple
With the polishing wheel 7 that is bonded inside pipeline, liquid spout is provided between adjacent polishing wheel；Before the both sides of grinding head are respectively equipped with
Auxiliary positioning mechanism 8, rear auxiliary positioning mechanism 9, auxiliary positioning mechanism include 3 to 6 positioning being vertically set on polishing bar
Column 10, positioning column top are equipped with universal ball wheel 11.
The preceding auxiliary positioning mechanism 8 is arranged on a free bar 12 being connected with polishing bar 4, free bar and polishing
Bar is connected by bearing 13.
The front end of the free bar 12 is inserted into a support rail 14, and support rail is vertically located at 2 side of fixed frame.
Welded tube fixed jaw 15 is additionally provided on the fixed frame 2,17 both ends of welded tube are respectively placed in welded tube fixed jaw and welded tube
On bracket 5, the stability of welded tube 17 is improved.
The side of the auxiliary positioning mechanism is equipped with rounded tabs 16, and water mist can be as possible retained in grinding head four
Reduce water consumption in week.
Elastic support is equipped between the universal ball wheel 11 and positioning column 10 so that ball wheel can be crossed to contract
The weld seam of annular, convenient for handling circular weld.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment, it is impossible to be construed as limiting the scope of the utility model.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should all still belong within the patent covering scope of the utility model.
