Abstract

The utility model relates to a grinding device of inner surface of a steel pipe, which is composed of a lathe body, a lathe body driving device and a grinding pole bracket on the lathe body; the grinding pole, a grinding pole driving device and a balance weight block at the tail end of the grinding pole are assembled into one body and are articulated on the grinding pole bracket, a grinding pole lifting device is arranged under the head part of the grinding pole independently and the head part of the grinding pole is provided with a sand wheel; the device has the advantages that the design of long grinding pole is adopted, the inner hole of the steel pipe of 12m in length can be ground, the grinding pole has the functions of lifting and regulating the pressure of the grinding head, the processing method is simple, the price is low and the finish quality of the grinding and polishing surface is higher than that of the inner boring external-lathing surface.

Description

The steel pipe internal-surface grinding attachment
Technical field:
The utility model relates to a kind of steel pipe internal-surface grinding attachment.
Background technology:
The enterprise of at present domestic and international processing seamless steel pipe is except that U.S. Wei Mangaodeng company, for internal diameter tube, all adopt method in rolling back machining, the outer car of promptly interior boring, it is rolling and process time is all very long, the metal cutting amount is big, and lumber recovery is low, the price height.And U.S. Wei Mangaodeng company takes the backward extrusion method with its patent, be about to preformed blank and be squeezed into heavy caliber seamless steel pipe, thereby make the machinery of steel pipe, it is best that the chemical property uniformity reaches, and the steel pipe of extruding need only be polished to the steel pipe surfaces externally and internally and both can.At present the device that carries out effective grinding for long steel pipe internal-surface does not have approved product.
The utility model content:
The purpose of this utility model is to provide a kind of steel pipe internal-surface grinding attachment that carries out grinding at long steel pipe internal-surface.
The technical solution of the utility model is: the steel pipe internal-surface grinding attachment is made up of car body, car body drive unit and the mill shaft bar that is installed on the car body, after being assembled into one, mill bar, mill rod driving device and mill bar tail end balancing weight be articulated on the mill shaft bar, mill bar lowering or hoisting gear independently is installed below the mill club head, and the mill club head is installed emery wheel.
Described mill bar comprises mandrel, long outer tube and the deep groove ball bearing between the two, uses the positioning sleeve location between bearing, and outer tube is provided with reinforcement.
Described mill bar lowering or hoisting gear adopts the feed screw nut lifting mechanism.
Advantage of the present utility model is to adopt the design of long mill bar, can carry out grinding to 12 meters long steel tube inner holes, the mill bar has elevating function and adjusts the function of wheelhead pressure size, and processing method is simple, price is low, and its polishing and polished surface than the outer car surface smoothness height of interior boring.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model mill bar structural representation.
Wherein 1 is mandrel; 2 are long outer tube; 3 is deep groove ball bearing; 4 is positioning sleeve; 5 is reinforcement.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further specified.
The utility model is made up of car body, car body drive unit and the mill shaft bar that is installed on the car body, after being assembled into one, mill bar, mill rod driving device and mill bar tail end balancing weight be articulated on the mill shaft bar, mill bar lowering or hoisting gear independently is installed below the mill club head, and the mill club head is installed emery wheel.
Because pipe to be processed is longer, generally about 12 meters, so the stability in order to guarantee that long mill bar is worked under high-speed rotating conditions will be ground bar and is designed to the structure as Fig. 2, select for use deep groove ball bearing to realize rotating between mandrel and the outer tube, use the positioning sleeve location between bearing.Outer tube is provided with reinforcement.In order not influence the straight degree of mandrel, guarantee the bearing installation accuracy, outer tube adopts 45 aluminium borings, and mandrel adopts the modified back of 45 steel machineds correct grinding, and bearing adopts imported bearing, has guaranteed to rotate freely no jam phenomenon after the mill bar overall package.
During the utility model work, earlier pipe fitting to be processed is placed on the support roller tire, drives the casting skin pipe with 50~60 rev/mins of rotations with the 7.5Kw motor by support roller, bistrique drives with 11KW driven by motor mill bar, with 1500 rev/mins the casting skin bore is carried out grinding.The car body drive unit adopts motor variable-frequency speed-regulating, makes the amount of feeding adjustable continuously between 20~50mm/min, drives car body and grind bar to move ahead.Lowering or hoisting gear adopts the feed screw nut lifting mechanism, drives the lifting of mill bar to satisfy the needs of grinding different tube diameters; Lever principle is adopted in the adjustment of wheelhead pressure, at the pressure of mill bar tail end by plus-minus balancing weight adjustment bistrique, makes wheelhead pressure in 30~50Kg scope, can avoid the irregular damage that emery wheel is caused because of the pipe fitting inner surface.
