The outer surface of steel tube grinding attachment
Technical field:
The utility model relates to a kind of outer surface of steel tube 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 outer surface of steel tube does not have approved product.
The utility model content:
The purpose of this utility model is to provide a kind of long steel pipe cylindrical to carry out the outer surface of steel tube grinding attachment of grinding.
The technical solution of the utility model is: the outer surface of steel tube grinding attachment comprises wheel holding mechanism and wheel grinding device, described wheel holding mechanism comprises car body, main driving motor, car motion motor, drive roll and driven voller, main driving motor, car motion motor, drive roll and driven voller all place on the car body, main driving motor is connected with drive roll by transmission system, and the car motion motor drives the straight reciprocating motion of car body on track by transmission system; Described wheel grinding device comprises column and motor fixing plate, the middle part of motor fixing plate and column top are hinged, one side of motor fixing plate is installed emery wheel, thereby opposite side is connected control emery wheel height by steel wire rope with the column base, motor is installed on the motor fixing plate, is connected by belt transmission between motor and the emery wheel; Described wheel grinding device independently is installed in described wheel holding mechanism one side.
Described column base is provided with worm-gear speed reducer, is connected with a side of motor fixing plate with steel wire rope by rope sheave.
Advantage of the present utility model is to have realized the cylindricalo grinding to the pipe fitting to be processed of length more than 12 meters, and processing method is simple, and polishing and polished surface are than the outer car surface smoothness height of interior boring.
Description of drawings:
Fig. 1 is a riding wheel structure schematic diagram of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a wheel grinding device schematic diagram of the present utility model;
Fig. 4 is a scheme of installation of the present utility model.
Wherein 1 is that car body, 2 is that main driving motor, 3 is that car motion motor, 4 is that drive roll, 5 is that driven voller, 6 is that column, 7 is that motor fixing plate, 8 is that emery wheel, 9 is that motor, 10 is that steel wire rope, 11 is that column base, 12 is that worm-gear speed reducer, 13 is a pipe fitting to be processed.
The specific embodiment:
Below in conjunction with drawings and Examples the utility model is further specified.
The wheel holding mechanism structure as shown in Figure 1, main driving motor drives the drive roll rotation by the chain transmission, drive roll drives steel pipe and rotates, driven voller mainly plays a supportive role, auxiliary rotation; The car motion motor rotates by chain driving-belt motor-car wheel, realizes the straight reciprocating motion of car body on track, thereby drives pipe fitting motion to be processed.Driving and driven roller is designed to removable, by axle and rolling ball bearing carrying roller is connected between two bearing blocks, and between two mutually corresponding carrying rollers, have row's installing hole, by bolt bearing block is fixed on the base, when needs rotate the steel pipe of various outer diameter, only need carrying roller be moved and be fixed on the corresponding installing hole and can realize by manual mode.
The wheel grinding device as shown in Figure 2, realize the high speed rotation of emery wheel between motor and the emery wheel by belt transmission, finish grinding to steel pipe, steel wire rope is connected with motor fixing plate, the other end connects worm-gear speed reducer by rope sheave, utilize handwheel to control the height of emery wheel, reach grinding different bore steel pipes.
The wheel grinding device independently is installed in described wheel holding mechanism one side, as shown in Figure 3.
