Background
In industrial production, welding of steel pipes and flanges is a common technological process and is widely applied to the fields of petroleum, chemical industry, machinery, electric power and the like.
The existing clamp usually adopts a single fixing mode, such as bolting or pressing by a pressing plate, and the fixing mode needs to frequently replace the clamp or adjust the fixing position when dealing with steel pipes and flanges with different specifications, so that the operation is complex.
Due to the variety of specifications of steel pipes and flanges, clamps are often difficult to accommodate workpieces of all sizes, resulting in limited practical use.

The utility model adopts the technical scheme that:
The utility model provides a flange joint welding process uses positioner, including operation panel and three-jaw chuck, three-jaw chuck includes the jack catch, the operation panel is square frame, operation panel upper portion and lower part are dull and stereotyped, the top fixed connection plane bearing bottom of operation panel, plane bearing upper portion fixed connection three-jaw chuck bottom, the top of operation panel is connected with three-jaw chuck through plane bearing rotation, four fixed blocks of outer wall fixedly connected with of three-jaw chuck, four fixed blocks evenly distributed is at the outer wall of three-jaw chuck, the top of fixed block has the clamp plate, the adjustment hole has been seted up to the clamp plate, the top threaded connection of fixed block has the clamp bolt, the clamp bolt runs through the adjustment hole, the clamp bolt has the clearance with the adjustment hole, the top bottom of clamp bolt is supported tightly with the top of clamp plate, the steel pipe cup joints at the jack catch outer wall, the outer wall bottom of steel pipe is cup jointed to the flange, the flange is in three-jaw chuck upper portion, the top of clamp plate bottom butt flange, rotate between the interior roof and the interior bottom wall middle part of operation panel is connected with the back shaft, the top of back shaft runs through the operation panel, the top and the bottom center fixed connection of three-jaw chuck of back shaft, the bottom of motor outer wall fixedly connected with bevel gear of motor, the bottom fixedly connected with bevel gear of motor and the interior bottom of back shaft is connected with bevel gear, two bevel gear of two fixed mounting, two bevel gear of operation fixedly mounted with, two bevel gear of motor fixedly mounted on the bottom of the top of the support shaft.
The utility model has the beneficial effects that:
according to the utility model, through the cooperation of the three-jaw chuck, the compression stud and the pressing plate, the steel pipe and the flange can be firmly fixed, so that shaking or displacement cannot occur in the welding process, and the welding quality is improved.
Because the adjusting holes are in clearance fit with the compression studs, the positions of the pressing plates can be adjusted according to flanges with different sizes, so that the clamp is suitable for welding steel pipes and flanges with various specifications.
The motor drives the three-jaw chuck to rotate, so that circumferential welding can be conveniently performed, and the welding efficiency is improved.

Detailed Description
As shown in fig. 1-5: the utility model provides a flange joint welding process is with positioner, including operation panel 1 and three-jaw chuck 2, three-jaw chuck 2 includes jack catch 14, operation panel 1 is square frame, operation panel 1 upper portion and lower part are the flat board, the top fixed connection plane bearing 3 bottom of operation panel 1, plane bearing 3 upper portion fixed connection three-jaw chuck 2 bottom, the top of operation panel 1 is rotated through plane bearing 3 and is connected with three-jaw chuck 2, the outer wall fixedly connected with four fixed blocks 4 of three-jaw chuck 2, four fixed blocks 4 evenly distributed is at the outer wall of three-jaw chuck 2, the top of fixed block 4 has clamp plate 5, adjusting hole 6 has been seted up to clamp plate 5, the top threaded connection of fixed block 4 has clamp stud 7, clamp stud 7 runs through adjusting hole 6, clamp stud 7 has the clearance with adjusting hole 6, the top bottom of clamp stud 7 supports with clamp plate 5's top tightly, the outer wall of jack catch 14, the outer wall of clamp stud 14 outer wall butt steel pipe 8, flange 9 is at the outer wall bottom of steel pipe 8, flange 9 is in three-jaw chuck 2 upper portion, the bottom butt flange 9 of clamp plate 5 top, the top of motor 10 has two inner supporting shaft 10 to be connected with the top shaft 12 of motor, the top shaft 10 is connected with two bevel gear 13 fixed connection bevel gear 13, the top shaft 13 fixed connection bevel gear 1, the top shaft 13 is connected with the inner bottom of motor 1, the top shaft 10 fixed shaft 13 is connected with the top of bevel gear 1.
The three jaw chuck 2 is a prior art device. The motor 12 is a self-locking motor and has a shutdown self-locking function.
Firstly, the steel pipe 8 to be welded is sleeved at the top of the three-jaw chuck 2, so that the inner wall of the steel pipe 8 is ensured to be in close contact with the outer walls of the jaws of the three-jaw chuck 2, and the preliminary fixing of the steel pipe 8 is realized.
Then, the flange 9 is sleeved on the bottom of the outer wall of the steel pipe 8, so that the position of the flange 9 is ensured to be correct.
Then, by rotating the press studs 7 on the four fixing blocks 4, the press studs 7 are contacted with the top of the pressing plate 5, and continuing to rotate the press studs 7 until the bottom of the pressing plate 5 is tightly abutted against the top of the flange 9, the press studs 7 can slide in the adjustment holes 6 due to the clearance between the adjustment holes 6 and the press studs 7, and the position of the pressing plate 5 can be adjusted as required, so that the flange 9 is ensured to be uniformly and firmly pressed.
Inside the operation table 1, a motor 12 is started, a bevel gear II 13 at the end head of an output shaft of the motor is meshed with a bevel gear I11 at the bottom of the outer wall of a supporting shaft 10, the supporting shaft 10 and a three-jaw chuck 2 fixedly connected with the supporting shaft are driven to rotate, and the three-jaw chuck 2 is rotationally connected on the operation table 1 through a plane bearing 3, so that the rotation of a steel pipe 8 and a flange 9 can be realized, and the welding operation is facilitated.
In the case where the steel pipe 8 and the flange 9 are fixed and rotatable, a welding operation is performed to firmly weld the steel pipe 8 and the flange 9 together. The utility model protects only the mechanical part, and the functions realized by the software control part related to the mechanical part are not within the protection scope of the utility model.
