Description
The utility model belongs to processing equipment, particularly a kind of tube head sander.
Install in the repairing trades at machine industry especially boiler, pressure vessel and equipment, pipe rises and connects the procedure that is absolutely necessary, and its quality and speed directly influence the quality and the speed of equipment.One important procedure that pipe rises before connecing is that the outer surface polishing of tube head is level and smooth, and this operation still adopts manually-operated at present, needs to polish with sandpaper by hand.Used tubing is tens at least in the manufacturing installation of every equipment and repair procedures, hundreds of root at most, rise simultaneously as two and to connect, tube head polishing amount more will double to carry out, and therefore, adopts time-consuming the taking a lot of work of manual operations, inefficiency and tube head polishing difficult quality guarantee, especially aspect tube head circularity, corner angle often occur, influence is risen and is connect quality.
The purpose of this utility model is to provide a kind of mechanically operated tube head sander, this sander wide adaptability, efficient height.
Tube head sander of the present utility model is by locking, transmission is polished and is controlled three parts and constitutes, described lock portion comprises a hollow locking frame, be movably installed with locking jaw on the locking frame, be fixed with extension spring on the locking jaw, described transmission polishing part comprises a polishing frame, abrasive material frame movable up and down is installed on the frame, mounting spring on the abrasive material frame, and at its end fixed-abrasive, the polishing frame is done 360 ° of rotations by Electric Machine Control, and described control section comprises a hollow center axle, in the axle activity centre axle is installed, be with the compression spring on the axle, the activity centre axle can move horizontally in the hollow center axle, is used to control the tube head position.
The self controllable locking of tube head sander of the present utility model, control polishing size needn't manual measurement, and the workpiece after the polishing is level and smooth, no corner angle, no matter buffing work-piece length and degree of crook all can be processed.This machine is simple in structure, and is easy and simple to handle, and the tube head of polishing was only used about 30 seconds, had improved work efficiency greatly.This machine can be used for the usefulness of the tube head polishing of manufacturings such as boiler or pressure vessel.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is according to the tube head sander structural representation that the utility model proposes.
Fig. 2 is a tube head sander lock portion structural representation.
Fig. 3 is a tube head sander polishing part-structure schematic diagram.
Fig. 4 is a tube head sander control structure schematic diagram.
1 is locking frame (hollow) among the figure, the 2nd, and locking frame lid, the 3rd, angle fan type locking jaw, the 4th, angle fan type locking jaw alignment pin, the 5th, extension spring alignment pin, the 6th, locking jaw control wheel, the 7th, control wheel operation bar, the 8th, bearing bearing support lid, the 9th, bearing bearing support, the 10th, bearing, the 11st, bearing support punching bolt, the 12nd, polishing frame, the 13rd, frame hollow shaft, the 14th, hollow shaft-cup, the 15th, hollow shaft polishing housing cap, the 16th, abrasive material frame, the 17th, abrasive material frame degree of tightness spring, the 18th, abrasive material, the 19th, belt pulley, the 20th, bearing bearing support bolt of cover setting, the 21st, hollow center axle, the 22nd, spring, the 23rd, central shaft bearing support, the 24th, activity centre axle, the 25th, motor, the 26th, V belt, the 27th, angle fan type locking jaw extension spring, the 28th, turn, the 29th, turn bearing pin, the 30th, hollow center axle bearing support nut, the 31st, activity centre spindle nut.
As shown in the figure, this sander body is divided into three parts, i.e. lock portion, transmission polishing part and control section.Lock portion mainly comprises a hollow locking frame 1, be equipped with on the frame and can see Fig. 2) by the angle fan type locking jaw 3(of locking jaw extension spring 27 pullings, angle fan type locking jaw 3 is fixing by alignment pin 4,27 of extension springs are fixed on the locking frame 1 by extension spring alignment pin 6, angle fan type locking jaw 3 is by 6 controls of locking jaw control wheel, with the operation of control wheel operation bar.Locking frame lid 2 is installed on the locking frame 1.Described transmission polishing part mainly comprises a polishing frame 12, and abrasive material frame 16 is installed on this frame, and compression spring 17 is housed on the abrasive material frame, and the abrasive material frame can be done upper and lower displacement, and abrasive material 18 is installed in its end.The rotation of polishing frame is to drive belt pulley by motor by belt to rotate, and the frame hollow shaft 13 that is attached thereto is rotated, and does 360 ° rotation thereby drive the polishing frame.Described control section mainly comprises a hollow center axle 21 and activity centre axle 24, activity centre axle 24 can insert in the hollow center axle 21 and move horizontally, mounting spring 22 on the axle 24, its end is positioned at the hollow machine chamber of sander frame under off working state, when workpiece inserts, its compression is retreated to certain position, make the buffed surface of workpiece enter hollow machine chamber.Can mounting spring circle 28 on the activity centre axle 24, scope with restraining spring activity in hollow center axle 21 cavitys, bearing pin 29 is installed on the turn, slot so that bearing pin 29 moves in groove at the inner surface of hollow shaft 21, such one is the polishing size that can control tube head, the 2nd, can prevent the rotation of activity centre axle 24.The afterbody of activity centre axle 24 is installed nut parent 31, is used to limit it and returns the position.Central shaft is installed in the bearing support 23.
The utility model is work like this: need the pipe fitting of polishing to insert from the intermediate hollow of locking frame 1, enter by locking jaw 3, frame hollow shaft 13 in the cavity of polishing frame 12 and promote activity centre axle 24 horizontal displacements, compression spring 22 is till the bearing pin 29 on turn 28 is walked on earth along the groove in the hollow center axle 21.At this moment the tube head of buffing work-piece just in time all enters the abrasive material place of polishing frame, and it is firmly fixing with pipe fitting that promotion control this moment wheel operation bar 7 makes locking jaw control wheel 6 stir locking jaw 3.Make motor 25 work then, under the driving of belt 26, thereby belt pulley 19 rotates the rotation that drive chassis hollow shaft 13 drives 360 ° in polishing frame 12 works, because tube head is fixed, frame 12 abrasive material 18 in running up contacts with tube head, thereby the outer surface of tube head is polished smooth.About about 30 seconds, work finished.After the tube head polishing was finished, pull joystick 7 again, discharged locking jaw 3, and pipe is extracted out.At this moment activity centre axle 24 horizontal displacement under the effect of spring 22, reenter the polishing frame 12 cavity in reset.
The utility model can adopt general machined to make, and described abrasive material can be an oilstone, and other parts can adopt materials such as cast iron, steel to make.The length of buffing work-piece is unrestricted, tube head diameter 25-89mm.
