A slide way is arranged on the positioning plate, a columnar left support plate is arranged in the slide way, one end of the left support plate is provided with a left roller, the shaft line of the left roller is parallel to the shaft line of the right roller and a lower roller is arranged on the bracket between the left roller and the right roller. The other end of the left supporting plate is provided with a blocking cover, the blocking cover is provided with a through hole, the bracket is provided with a threaded supporting seat and a screw rod is arranged in the threaded supporting seat. The screw rod is penetrated through the through hole in the blocking cover, the screw rod is fixedly provided with a bearing and the outer diameter of the bearing is larger than the diameter of the through hole in the blocking cover. The screw rod is sheathed with a spring and a cup-shaped shaft sleeve, the spring is positioned in the cup-shaped shaft sleeve, and the cup-shaped shaft sleeve is fixedly connected with the blocking cover. The special clamp for a submerged-arc welder can ensure the easy movement of pipes and can keep the relative positions of the pipes fixed, and thus order welding seams are ensured.
Description
Technical field
The utility model belongs to welding equipment, relates in particular to a kind of submerged-arc welding dedicated jig.
Background technology
Often adopt submerged welding process when making metal tube, when two and half sheet tubing being welded into a complete pipe, must guarantee the neat of weld seam.And when the bigger pipe of weld length, also will constantly mobile tubing, tubing is moved easily and also to guarantee to move in relative position fixing of two tubing, just corresponding apparatus must be arranged.
Summary of the invention
The purpose of this utility model provides a kind of submerged-arc welding dedicated jig that can make tubing move and can keep the tubing relative position easily.
For achieving the above object, the utility model adopts following technical scheme: a kind of submerged-arc welding dedicated jig, comprise support, right supported plate is housed on the support, right roller is housed on the right supported plate, location-plate also is housed on the support, chute is arranged on the location-plate, the left supported plate of column casing shape is contained in the chute, left supported plate one end is equipped with left wheel, and left wheel axis and right roller shaft line parallel are equipped with bottom roller on the support between left wheel and the right roller, the left supported plate other end is equipped with door, through hole is arranged on the door, thread support also is housed on the support, screw rod is housed in the thread support, screw rod passes the through hole on the door, be fixed with bearing on the screw rod, the external diameter of bearing is set with spring and cup-shaped axle sleeve greater than the diameter of through hole on the door on the screw rod, spring is positioned at cup-shaped axle sleeve, and cup-shaped axle sleeve and door are connected.
Right roller shaft links to each other with reducing motor.
Described left wheel and right roller respectively have two, and the projection join line of four rolling axis on the support plane is rectangle.
This submerged-arc welding dedicated jig, promoting left supported plate by screw rod moves in chute, and left wheel is conformed to size of pipe and tubing with distance between the right roller, spring shrinks when stressed, the drive left wheel retreats, can change distance between left wheel and the right roller to adapt to the minor variations of size of pipe and tubing, and can make left wheel and right roller clamp tubing, and the mating reaction of bottom roller and left and right roller can reduce the resistance of tubing in moving, this has just guaranteed that tubing is both mobile easily and can keep the fixing of its relative position, has therefore guaranteed that also weld seam is neat.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view at left supported plate position.
Fig. 3 is that the A-A of Fig. 1 is to view.
The specific embodiment
As Fig. 1, Fig. 2, submerged-arc welding dedicated jig shown in Figure 3, comprise support 13, right supported plate 12 is housed on the support, right roller 10 is housed on the right supported plate 12, location-plate 14 also is housed on the support 13, on the location-plate 14 chute is arranged, the left supported plate 7 of column casing shape is contained in the chute, and left supported plate 7 one ends are equipped with left wheel 8, left wheel axis and right roller shaft line parallel, the left supported plate other end is equipped with door 3, on the door 3 through hole is arranged, thread support 2 also is housed on the support, screw rod 1 is housed in the thread support 2, screw rod passes the through hole on the door, be fixed with bearing 4 on the screw rod 1, the external diameter of bearing is set with brute spring 5 and cup-shaped axle sleeve 6 greater than the diameter of through hole on the door on the screw rod 1, spring 5 is positioned at cup-shaped axle sleeve 6, and cup-shaped axle sleeve 6 is connected with door 3.Spring shrinks when stressed, can change two distances between the roller adapting to the minor variations of size of pipe and tubing, and can make left wheel 8 and right roller 10 clamp tubing.Several bottom rollers 9 are housed on the support between left wheel 8 and the right roller 10, and the mating reaction of bottom roller 9 and left wheel 8, right roller 10 can reduce the friction between tubing and the support, and tubing is moved easily.
Also can right roller shaft link to each other,, make it finish self-feeding by the right roller rotation of driven by motor with deceleration device 11 by driven by motor.
The shape of roller can such as when square tube is made in weldering, preferably be used cylindrical roller according to the change of shape of tubing, because the contact-making surface maximum of cylindrical roller and tubing, and when weldering rounding pipe, then can adopt the roller that has identical radian measure to increase contact-making surface.
Left wheel and right roller respectively have two, and the projection join line of four rolling axis on the support plane is rectangle.Four rolling can shared two support plates, promptly adorn two left wheel on the left supported plate, adorn two right rollers on the right supported plate, but also each roller are contained in respectively on the support plate, form the position two symmetrical groups.Certainly the number of roller can also be three pairs or more more, and the number of reducing motor can not increase, and drives arbitrary right roller with a reducing motor and gets final product.
This submerged-arc welding dedicated jig in use, elder generation's rotating screw bolt 1, making screw rod promote left supported plate 7 moves in chute, thereby left wheel 8 is conformed to substantially with size of pipe and tubing with distance between the right roller 10, preferably make distance between left wheel and the right roller be slightly less than the size of tubing, can tubing be held tighter by the elastic force of spring like this.Then tubing is pushed between left wheel and the right roller, the right roller of driven by motor rotates, and by frictional force tubing is moved forward, and can finish self-feeding.
