Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-2, the combined elbow butt welding tool comprises an operation plate 1, wherein the operation plate 1 is of a rectangular structure, so that an operator can work conveniently. Two sliding plates 2 are transversely arranged on the operating plate 1 in parallel, a longitudinal groove track 11 is arranged on the operating plate 1, sliding blocks are arranged at the lower ends of the two sliding plates 2, and the two sliding plates 2 are close to and far away from each other through the sliding of the sliding blocks on the groove track 11.

For convenient control, a left screw 12 and a right screw 13 are arranged on the side surfaces of the two sliding plates, and the left screw 12 and the right screw 13 are longitudinally arranged on the operating plate 1 in parallel. And the two sliding plates are provided with a screw nut 14 matched with the left screw rod and the right screw rod, the screw nut 14 is driven by a motor, and the two sliding plates realize the approaching and the separating of the distance under the action of the screw rod and the screw nut.

In fact, the groove track 11 and the sliding block play a role in guiding, and the left lead screw, the right lead screw and the nut play a role in power.

And the two sliding plates are respectively provided with a clamping column 3, and the two clamping columns correspond to the two sliding plates. The specific structure installation: the clamping column 3 comprises an upright column 31 and a clamping piece 32 installed on the upright column 31, the lower end of the upright column 31 penetrates through the sliding plate 2, a vertical screw 33 parallel to the upright column 31 is arranged on the side face of the upright column 31, a motor matched with the vertical screw 33 is arranged on the sliding plate 2, and the motor drives the clamping column 3 to move up and down relative to the sliding plate 2.

The two clamping columns described above are moved up and down by the vertical screw 33, while the two clamping columns are moved closer to and further away from each other by the sliding plate.

The holder 32 is formed in a U-shape, and cushions 321 are provided on both sides of an inner wall of the holder 32, and the cushions 321 are adjusted to have a distance therebetween by bolts.

Centrally between the two sliding plates is arranged a load-bearing column 4, said load-bearing column 4 being mounted vertically on a hydraulic cylinder 5. The bearing column 4 comprises a connecting column 41 and a bearing platform 42 arranged on the connecting column, wherein the connecting column 41 is arranged on a piston of a hydraulic cylinder.
