Flexible clamp for pipe fitting welding is when adjusting, and the guide rail that provides X, Y, Z direction to move adjustment is arranged on the top of fixture rather than is placed on the work top of clamp body, can effectively avoid the impact of welding slag.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 around X, Y, tri-directions of Z, realize that detent mechanism 3 is around three reference axis adjustment anglecs of rotation, and can self-locking.Detent mechanism 3 connects by pin the replaceability that single tine joint 5 has guaranteed clamp mechanism 2 and detent mechanism 3, configures corresponding clamp mechanism 2 and detent mechanism 3 according to the different specification size pipe fitting quickly and easily.Operate the second power source 34, top directions X displacement governor motion slide block 13 drives moving left and right of top directions X displacement governor motion 12 by rack-and-pinion, thereby drives the adjustment of displacement that detent mechanism 3 is realized along directions X.Operate the first power source 33, make top Y-direction shift adjusting machine 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 adjustment of displacement that detent mechanism 3 is realized along Y-direction.Operate the 3rd power source 35, top Y-direction shift adjusting machine 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 adjustment of displacement that detent mechanism 3 is realized along the Z direction.The vertical Z direction displacement governor motion 16 of welded flange is the mechanism that adopts pinion and rack to drive ring flange and connection along Z direction adjustment of displacement, adjust the Connection Block 24 that waits minute chute ring flange rotating mechanism 14, half range sector gear engagement rotation regulating mechanism 15 and be provided with angle-adjusting mechanism, thereby adjust the anglec of rotation of weldment ring flange around X, Y, tri-directions of Z, the accurate location of flange, the dislocation while having avoided pipeline finally to install.
Because the hop count of weld-end fittings is changeable, WhenThe hop count of pipe fitting equals at 2 o'clock, and the location clamping regulation mechanism that adopts 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 is adjusted.If the pipe fitting hop count equals 3, adopt 3 above-mentioned location clamping regulation mechanisms to be adjusted, directly use Fig. 1 to get final product.If the pipe fitting hop count is greater than 3, also adopt 3 above-mentioned location clamping regulation mechanisms to be adjusted, but pipe fitting first will be divided into groups, AdoptEvery group be 2 sections pipe fittings the combination adjustment or Every group isThe combination adjustment of 3 sections and 1 section, realize welding circularly.Below set forth respectively 2 sections pipe fittings, 3 sections pipe fittings, the location of the weld jig of the combined pipe fitting more than 3 sections clamps method of adjustment:
The location that is as shown in Figure 62 sections pipe fittings clamps, and adopts 2 location clamping regulation mechanisms.First the weldment flange is fixed on minute chute rotating mechanism 32 such as decile chute ring flange rotating mechanism 14 and end flange by bolt-connection, first paragraph pipe fitting I is fixed on decile chute ring flange rotating mechanism 14 again, utilize the stiff end flange to be adjusted around 8 pairs of first paragraph pipe fitting I of Y-axis angle-adjusting mechanism around Z axis angle-adjusting mechanism 7 and stiff end flange, after adjustment, by detent mechanism 3 and clamp mechanism 2, clamp pipe fittings.In the situation that guarantee that the relative position of first paragraph pipe fitting I requires, second segment pipe fitting II is fixed on minute chute rotating mechanism 32 such as end flange, the end face of base seat support 1 of take is benchmark, adjust position and the angles of the 2nd group of pipe fitting location clamping regulation mechanism, and adjust position and the angles of minute chute rotating mechanism 32 such as end flange simultaneously, relocate and clamp second segment pipe fitting II.
The location that is as shown in Figure 73 sections pipe fittings clamps state diagram, to the location of 2 sections pipe fittings in Fig. 6, clamps similarly, and difference is only to have increased by 1 pipe fitting location clamping regulation mechanism, has adopted 3 location clamping regulation mechanisms.At the 2nd and the 3rd, locating between clamping regulation mechanism is the 3rd section pipe fitting III.
The location that is as shown in Figure 8 the combined pipe fitting more than 3 sections clamps, the 4 sections pipe fittings of take are example, provide two kinds of packet modes to realize the adjustment of 4 sections pipe fittings, the first packet mode is: 4 sections pipe fittings are divided into to two groups, every group is 2 sections pipe fittings, be that first paragraph pipe fitting I and second segment pipe fitting II are one group, the 3rd section pipe fitting III and the 4th section pipe fitting IV are another groups, last again by these 2 groups of pipe fitting Combination Welding of having welded.The second packet mode is: 4 sections pipe fittings are divided into to two groups, one group is 3 sections, another group is 1 section, be that first paragraph pipe fitting I, second segment pipe fitting II and the 3rd section pipe fitting III are one group, the 4th section pipe fitting IV is another group, first adjust 3 sections pipe fittings and welded, then 3 sections pipe fittings and remaining 1 section pipe fitting welding that will weld.While adopting the first packet mode, adopt 2 the location clamping regulation mechanisms identical with Fig. 6.While taking the second combination, the adjustment welding between 3 sections pipe fittings wherein, adopt 3 the location clamping regulation mechanisms identical with Fig. 7, and the adjustment welding of 1 section remaining pipe fitting adopts 2 the location clamping regulation mechanisms identical with Fig. 6.By that analogy, for the combination method of adjustment of multistage pipe fitting more, be all the adjustment welding first realized between 2 sections or 3 sections, then with other pipe fitting combination.
