Specific embodiment

Below in conjunction with attached drawing, specific embodiment of the present utility model is described in further detail, so that the utility model skill Art scheme is more readily understood and grasps.

Embodiment:

Referring to Fig.1 shown in -3, the present embodiment provides a kind of steel-pipe welding machine people to use fixed device, including pedestal 1, pedestal Two identical clamping devices are symmetrically arranged on 1；Clamping device includes the supporting plate 21 being fixedly connected on pedestal 1 vertically；Supporting plate A horizontally disposed casing 22 is rotatably connected to by bearing on 21, middle sleeve 22, which is located on the tube wall in 21 outside of supporting plate, to be set There is thread segment；Casing 22 is symmetrically arranged with the activity that two identical and vertical activities run through 22 tube wall of casing on the tube wall of outer end Bar 23；One end that motion bar 23 is located in casing 22 is fixedly connected with one along the horizontally disposed pressing plate of 22 length direction of casing 24, the other end of motion bar 23 is fixedly connected with a slippery fellow 25, and is arranged on the bar wall that is located at outside casing 22 of motion bar 23 Spring 26, wherein the both ends of spring 26 are fixedly connected with 22 outer wall of casing and foxy 25 bottoms respectively；Casing 22 has thread segment Tube wall on be threaded with a nut 27；The outer end of nut 27 is fixedly connected with a horn-like vestlet 28；Two Casing 22 is sequentially connected by driving mechanism, rotates the equidirectional same speed of two casings 22 together by driving mechanism.

When fixing steel pipe to be welded by above-mentioned setting, two steel pipes to be welded are respectively fixed to clamping machine first On structure, specifically: by taking the clamping device in left side as an example, it in steel pipe threading 22, will guarantee that steel pipe is located at two at this time first Between a pressing plate 24, then start rotating nuts 27, under the thread segment effect on 22 tube wall of casing, nut 27 can be made to transport to the left Dynamic, the vestlet 28 for being fixed on 27 left end of nut at this time also can be together toward left movement, so that the inner wall of vestlet 28 can be squeezed constantly simultaneously The slippery fellow 25 of two 23 upper ends of motion bar is pressed, to make two motion bars 23 constantly to middle slip, two pressing plates 24 at this time It can gradually be drawn close to centre, steel pipe can be pressed in centre by final two pressing plates 24, and stop rotating nut 27 at this time, i.e. completion steel pipe Fixation, steel pipe at this time is overlapped with the central axes of casing 22, so steel pipe can be rotated coaxially with casing 22；Exist at this time Under the driving of driving mechanism, two casings 22 can be made coaxial, in the same direction, and rotate with speed, thus make two it is to be welded Steel pipe is coaxial, in the same direction, and rotates with speed.It should be noted that make two steel pipes when fixing two steel pipes respectively Opposite end in contact.The contact surface that the welding gun 4 of welding robot is aligned to two steel pipes is only needed to be welded at this time.

Driving mechanism includes being rotatably connected on horizontally disposed shaft 31 between two supporting plates 21；Two casings 22 are close to interior Identical driven gear 32 is fixedly connected on the tube wall at end；Identical driving gear there are two being fixedly connected in shaft 31 33, wherein driving gear 33 and driven gear 32 are corresponded and are intermeshed；One end activity of shaft 31 through supporting plate 21 and It is sequentially connected with retarder 34, retarder 34 is sequentially connected with motor 35.

By above-mentioned setting, motor 35 will drive shaft 31 under the action of retarder 34 and rotate at a slow speed, in shaft 31 Under drive, two driving gears 33 in shaft 31 start to rotate, and then the driven gear 32 on casing 22 is driven to rotate respectively, It can make equidirectional two casings 22 at this time, same to speed, rotate coaxially.

The V-shaped groove 241 of an indent is offered on the opposite end face of two pressing plates 24.Setting forming V-shape can be convenient folder Hold steel pipe.

The cross section of motion bar 23 is in polygon.The purpose for being arranged to polygon is to prevent motion bar 23 from rotating.

The top of slippery fellow 25 is smooth circular arc plush copper structure.It is arranged to smooth circular arc plush copper structure purpose to be, makes vestlet 28 fine Compressive activities bars 23.

To sum up, the utility model can clamp two needs by two opposite clamping devices respectively and be welded to together Steel pipe, can be by steel pipe clamping among casing 22, and by the utility model by steel pipe clamping by turn nut 27 It can guarantee the coaxial of steel pipe and casing 22 when in casing 22, thus in the case where driving mechanism drives rotation, it is ensured that two Steel pipe to be welded is coaxially rotated together with speed is equidirectional, so that welding robot be facilitated to weld two steel pipes；And this reality With the novel steel pipe that can clamp a variety of radiuses.

The representative instance of above only the utility model, in addition to this, the utility model can also have other a variety of specific Embodiment, all technical solutions formed using equivalent substitution or equivalent transformation, all falls within the model of the requires of the utility model protection Within enclosing.
