24, 24 fixed connection of adaptor is on a lateral wall that baffle 22 is close to closing plate 21.

The internal rotation of adaptor 24 is connected with threaded rod 25, be equipped with the scale stripe on the threaded rod 25, be equipped with the screw hole on the closing plate 21, the one end threaded connection that adaptor 24 was kept away from to threaded rod 25 is in the screw hole, through rotatory threaded rod 25, can be with the help of the threaded connection effect between threaded rod 15 and the screw hole, make threaded rod 25 precession or screw hole out, and then drive baffle 22 along the inside wall horizontal slip of liquid reserve tank 20, adjust baffle 22's position, thereby the realization is kept away from the adjustment of the volume in the space that separates between a closing plate 21 lateral wall and the liquid reserve tank 20 to baffle 22.

Be equipped with communicating pipe 26 on the liquid reserve tank 20, sliding connection has the automatic formula that resets telescopic piston between a lateral wall that the baffle 22 kept away from sealing plate 21 and a inside wall of liquid reserve tank 20, the automatic formula that resets telescopic piston includes U-shaped piston 27, sliding connection has slide 28 in the U-shaped piston 27, fixedly connected with tension spring 29 between slide 28 and U-shaped piston 27's an inside wall, U-shaped piston 27 and the equal sliding connection of slide 28 are in liquid reserve tank 20, fixedly connected with reset spring 30 between a lateral wall of U-shaped piston 27 and a inside wall of liquid reserve tank 20.

Because U-shaped piston 27 and slide 28 can support respectively all the time on the lateral wall that the closing plate 21 was kept away from to the inside wall of liquid reserve tank 20 and baffle 22 under tension spring's 29 elasticity effect, consequently this automatic formula telescopic piston's that resets size can keep away from carrying out the self-adaptation adjustment of the volume in the space that separates between closing plate 21 lateral wall and the liquid reserve tank 20 according to baffle 22 for it can play the sealed piston effect always, liquid reserve tank 20 is kept away from and is equipped with guide hole 31 on the lateral wall of closing plate 21, fixedly connected with is just to the spacing pipe 32 that guide hole 31 set up on the lateral wall of liquid reserve tank 20, sliding connection has baffle 33 in the spacing pipe 32, fixedly connected with runs through the ratch 34 of spacing pipe 32 on the lateral wall that liquid reserve tank 20 was kept away from to baffle 33.

The rack bar 34 is connected with the half gear 19 in a meshed mode, the bottom side wall of the mounting plate 3 is fixedly connected with a pressure lever 35 which is just opposite to the U-shaped piston 27, a pressure storage device is arranged on the limiting pipe 32 and comprises a guide pipe 36, the guide pipe 36 is fixedly connected to the upper end face of the limiting pipe 32, the guide pipe 36 is far away from the liquid storage box 20, and the guide pipe 36 is far away from one end of the limiting pipe 32 and is fixedly connected with an elastic air bag 37.

When telescopic cylinder 2 drives depression bar 35 through mounting panel 3 and pushes down, after depression bar 35 got into communicating pipe 26 and pressed on U-shaped piston 27, along with telescopic cylinder 2's continuation shortens, depression bar 35 is pressing the vertical downstream of U-shaped piston 27, make reset spring 30 compressed, baffle 22 is kept away from the hydraulic oil in the space that separates between a closing plate 21 lateral wall and the liquid reserve tank 20 and is impressed in spacing pipe 32 through guide hole 31, thereby top baffle 33 slides along spacing pipe 32's inside wall, make ratch 34 stretch out spacing pipe 32, and then through the meshing connection effect with between the semi-gear 19, it is rotatory to drive the inside card fixed pipeline of pipe strap 18, so that carry out all-round welding to the junction of two pipelines under the circumstances that need not rotatory laser welder 8.

And when the rack bar 34 extends to the longest length, the gear formed by splicing the two half gears 19 just drives the pipe clamp 18 to rotate for a circle, sometimes because of the difference of the materials of the pipelines to be welded, the time required by the pipeline welding is different, some time required by the pipeline welding is shorter, and some time required by the pipeline welding is longer, namely the welding speed needs to be adjusted correspondingly according to the materials of the pipelines to be welded, but under the condition that the telescopic speed of the telescopic cylinder 2 is fixed, the accurate adjustment of the welding speed is not well realized, but in the invention, if the speed of the laser welder 8 for welding the pipeline needs to be adjusted, the rotating speed of the pipe clamp 18 is adjusted by only adjusting the rotating speed of the pipe clamp 18, namely adjusting the speed of the rack bar 34 extending out of the limit pipe 32, under the condition that the telescopic cylinder 2 drives the pressure lever 35 to press down at a fixed speed, the volume of the space between the side wall of the partition plate 22 far from the sealing plate 21 and the liquid storage tank 20 is adjusted, and the speed of the hydraulic oil entering the limiting pipe 32 through the guide hole 31 can be controlled.

Set for initial welding speed to be slowest speed, so after having adjusted laser welder 8 to pipeline welded speed, the baffle 22 is kept away from the sealed 21 a lateral wall and the stock solution case 20 between the space of isolating the volume must be the increase, so the hydraulic oil total amount must be greater than spacing pipe 32's holding capacity in this space, at this moment, unnecessary hydraulic oil can be followed pipe 36 and got into in the elasticity gasbag 37 by temporary storage, after the work, when control telescopic cylinder 2 extension was reset, the hydraulic oil of storage in the elasticity gasbag 37 is at first followed pipe 36 entering spacing pipe 32 under the pressure effect, then get back to in the stock solution case 20 along guide hole 31, later ratch 34 just resets under the drive of baffle 33.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
