Problems solved by technology

However, due to the smoothness of the outer wall of the pipe during welding, it is difficult to fix it, and the fixing tooling of the pipe is not stable to the pipe shell, so it is easy to shake when the pipe shell is welded, resulting in poor welding quality, which often fails to meet expectations In addition, the existing pipe welding fixture is troublesome to adjust, cannot adapt to pipes of different diameters, cannot accurately adjust the welding angle of the pipe, and has poor clamping stability

Embodiment 1

[0033] Such as figure 1 As shown, a pipeline welding self-adaptive fixture of the present invention includes a base 1, a support column 2 and an installation block 3, the support column 2 is arranged at both ends of the base 1, and the installation block 3 is arranged on the support column 2, and the installation A support space is provided between the blocks 3, and a jack post 5 for placing the pipeline 15 is arranged in the support space, and an oil cylinder 4 is arranged on the base 1, and the jack post 5 is connected to the top shaft of the oil cylinder 4 through a guide mechanism; the setting of the guide mechanism It can play an effective guiding role in the movement direction of the support 5, avoid misalignment, and ensure precise operation during the movement. Through the extension and contraction of the top shaft of the oil cylinder 4, the rise and fall of the support 5 are realized so as to realize the take-off and landing of the pipeline 15.

[0034] The mounting ...

Embodiment 2

[0042] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the longitudinal corner block 31 also includes a support block 16 arranged on its top, and the clamping section 103 slides through the support block 16 and the locking sleeve 161 on the support block 16 set on the support block 16. The outer diameter of the locking sleeve 161 shrinks in the direction away from the support block 16. The locking sleeve 161 is provided with a number of scaling grooves 163 that facilitate the scaling of the locking sleeve 161. The locking sleeve 161 is threadedly connected with a compression ring. 162.

[0043] In use, when the pipe is clamped and the pressure ring 162 is twisted, the pressure of the pressure ring 162 on the locking sleeve 161 gradually increases due to the diameter change of the locking sleeve 161 . At the same time, the positive pressure of the locking sleeve 161 on the clamping section 103 also increases, and the relative fricti...

Embodiment 3

[0045] Such as figure 2 and 3 As shown, the base 1 also includes support legs 104, worm 17, sliding base 18 and adjustment cylinder 107; The guide rod 14 is arranged on the sliding base 18 , and the adjusting cylinder 107 is arranged on the base 1 parallel to the sliding base 18 .

[0046] One end of the adjustment cylinder 107 is connected with the gear cover 108 on the base 1 , and the adjustment cylinder 107 is provided with an adjustment ball 109 connected with the driving gear 110 , and the driving gear 110 is arranged in the gear cover 108 .

[0047] The worm 17 is arranged in the base 1 and is connected with the base 18; one end of the worm 17 is connected with the adjusting collar 171 through a ratchet, and the other end is provided with a driven gear 172 with a smaller diameter, and the driven gear 172 is connected with the driving gear 110 .

[0048] An adjusting screw 105 is connected to the supporting leg 104 , the adjusting screw 105 passes through the base 1 ...

Abstract

The invention discloses a self-adapting tool clamp for pipeline welding, and relates to the technical field of pipeline welding. The self-adapting tool clamp for the pipeline welding is high in clamping stability and high in adaptability. The self-adapting tool clamp for the pipeline welding comprises a base, supporting columns and mounting blocks, wherein the supporting columns are arranged at two ends of the base; the mounting blocks are arranged on the supporting columns, and a supporting space is formed between the mounting blocks; a propping column for positioning a pipeline is arranged in the supporting space; an oil cylinder is arranged on the base; the propping column is connected to a propping shaft of the oil cylinder through a guide mechanism; the pipeline to be welded can be clamped through a clamping device, so that the stability of the pipeline in welding is greatly improved, and the pipeline welding efficiency is effectively improved; a sliding inclination block is arranged, and thus the pipeline with different diameter can be clamped, and the applicable scope is wide. The self-adapting tool clamp for the pipeline welding is reasonable in structure, novel in design,simple to fix and operate, and stable to fix; the pipeline welding quality is effectively improved; and the self-adapting tool clamp for the pipeline welding is convenient to popularize and use.

Description

technical field [0001] The invention relates to the technical field of pipeline welding, in particular to a self-adaptive fixture for pipeline welding. Background technique [0002] Welding: also known as welding and welding, is a manufacturing process and technology for joining metal or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. However, due to the smoothness of the outer wall of the pipe during welding, it is difficult to fix it, and the fixing tooling of the pipe is not stable to the pipe shell, so it is easy to shake when the pipe shell is welded, resulting in poor welding quality, which often fails to meet expectations In addition, the existing pipe welding fixtures are cumbersome to adjust, cannot adapt to pipes of different diameters, cannot accurately adjust the welding...
