Pipe fitting welding flexible fixture is when adjusting, and the guide rail that provides X, Y, Z direction to move adjustment is arranged on the top of anchor clamps rather than is placed on the work top of clamp body, can avoid the influence of welding slag effectively.Clamp pipe fitting with clamp mechanism 2, adjust the universal pedestal 6 of chuck, angle adjustment turntable 4 and be provided with angle-adjusting mechanism Connection Block 9, thereby adjust the anglec of rotation of detent mechanism 3, realize detent mechanism 3, and can self-locking around three reference axis adjustment anglecs of rotation around X, Y, three directions of Z.Detent mechanism 3 connects the replaceability that single tine joint 5 has guaranteed clamp mechanism 2 and detent mechanism 3 by pin, quickly and easily according to corresponding clamp mechanism 2 and the detent mechanism 3 of different specification size pipe fitting configuration.Operate second power source 34, top directions X displacement governor motion slide block 13 drives the move left and right of top directions X displacement governor motion 12 by rack-and-pinion, thereby drives the displacement adjustment that detent mechanism 3 is realized along directions X.Operate first power source 33, make top Y direction displacement guiding mechanism screw mandrel 29 and top Y direction displacement governor motion slider nut 22 realize relative motion, drive top Y direction displacement governor motion 10 and move forward and backward, thereby drive the displacement adjustment that detent mechanism 3 is realized along the Y direction.Operate the 3rd power source 35, top Y direction displacement guiding mechanism screw mandrel 29 and top Y direction displacement governor motion slider nut 22 are realized relative motion, drive vertical Z direction displacement governor motion 11 and move up and down, thereby drive the displacement adjustment that detent mechanism 3 is realized along the Z direction.The vertical Z direction displacement governor motion 16 of welded flange is that the mechanism that adopts pinion and rack to drive ring flange and connection adjusts along the displacement of Z direction, adjustment waits branch chute ring flange rotating mechanism 14, half range sector gear engagement rotation regulating mechanism 15 and is provided with the Connection Block 24 of angle-adjusting mechanism, thereby adjust the anglec of rotation of weldment ring flange around X, Y, three directions of Z, the accurate location of flange, the dislocation when having avoided pipeline to install at last.
Because the hop count of weld-end fittings is changeable,
WhenThe hop count of pipe fitting equals at 2 o'clock, and the location of adopting 2 top Y direction displacement governor motions 10, vertical Z direction displacement governor motion 11 and top directions X displacement governor motion 12 to form clamps guiding mechanism and adjusts.If the pipe fitting hop count equals 3, adopt 3 above-mentioned location to clamp guiding mechanism and adjust, promptly directly use Fig. 1 to get final product.If the pipe fitting hop count greater than 3, also adopts 3 above-mentioned location to clamp guiding mechanism and adjusts, but pipe fitting will be divided into groups earlier,
AdoptEvery group be 2 sections pipe fittings the combination adjustment or
Every group isThe combination adjustment of 3 sections and 1 section realizes welding circularly.Below set forth 2 sections pipe fittings, 3 sections pipe fittings respectively, the location of the weld jig of the combined pipe fitting more than 3 sections clamps method of adjustment:
The location that is 2 sections pipe fittings as shown in Figure 6 clamps, and adopts 2 location to clamp guiding mechanism.Earlier be fixed on the weldment flange on the branch chute rotating mechanisms 32 such as five equilibrium chute ring flange rotating mechanism 14 and terminal flange with Bolt Connection, first section pipe fitting I is fixed on the five equilibrium chute ring flange rotating mechanism 14 again, utilize the stiff end flange to adjust around 8 pairs of first section pipe fitting I of Y-axis angle-adjusting mechanism, adjust finish back detent mechanism 3 and clamp mechanism 2 clamping pipe fittings around Z shaft angle degree guiding mechanism 7 and stiff end flange.Under the situation that the relative position that guarantees first section pipe fitting I requires, second section pipe fitting II is fixed on the branch chute rotating mechanisms 32 such as terminal flange, end face with base seat support 1 is a benchmark, adjusting the 2nd group of pipe fitting location clamps the position of guiding mechanism and puts angle, and adjust the position of branch chute rotating mechanisms 32 such as terminal flange simultaneously and put angle, relocate and clamp second section pipe fitting II.
The location that is 3 sections pipe fittings as shown in Figure 7 clamps state diagram, to the location of 2 sections pipe fittings among Fig. 6 clamp similar, different only be to have increased by 1 pipe fitting location to clamp guiding mechanism, promptly adopted 3 location to clamp guiding mechanisms.Locating between the clamping guiding mechanism at the 2nd and the 3rd is the 3rd section pipe fitting III.
The location that is the combined pipe fitting more than 3 sections as shown in Figure 8 clamps, with 4 sections pipe fittings is example, provide two kinds of packet modes to realize the adjustment of 4 sections pipe fittings, first kind of packet mode is: 4 sections pipe fittings are divided into two groups, every group is 2 sections pipe fittings, promptly first section pipe fitting I and second section pipe fitting II are one group, and the 3rd section pipe fitting III and the 4th section pipe fitting IV are another groups, will weld these good 2 groups of pipe fitting Combination Welding at last again.Second kind of packet mode is: 4 sections pipe fittings are divided into two groups, one group is 3 sections, another group is 1 section, promptly first section pipe fitting I, second section pipe fitting II and the 3rd section pipe fitting III are one group, the 4th section pipe fitting IV is another group, adjust 3 sections pipe fittings earlier and weld, 3 sections pipe fittings that will weld again weld with remaining 1 section pipe fitting.When adopting first kind of packet mode, adopt 2 location identical to clamp guiding mechanism with Fig. 6.When taking second kind of compound mode, the adjustment welding between 3 sections pipe fittings wherein adopts 3 location identical with Fig. 7 to clamp guiding mechanism, and the adjustment welding of 1 section remaining pipe fitting adopts 2 location identical with Fig. 6 to clamp guiding mechanism.By that analogy, at the combination method of adjustment of multistage pipe fitting more, all be the adjustment welding between realizing 2 sections or 3 sections earlier, again with other pipe fitting combination.
