Embodiment Construction

[0025] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0026] like figure 1 As shown, the umbrella-shaped inner support fixture for welding is composed of four parts: the main shaft 1, the front-end locking device, the weld seam tightening device, and the rear-end pressing device. The main shaft 1 connects the three major devices into one body. become one. The overall length of the umbrella-shaped inner support fixture is 3162 mm. figure 1 Marked with a double dotted line in is the cylindrical workpiece to be welded.

[0027] like image 3 As shown, the front-end locking device consists of front-end cover 2, front plug 3, bolt 4, tension ring I5, load-bearing ring I6, sleeve I7, load-bearing nut 8, tension ring II9, load-bearing ring II10 and sleeve Composition of cylinder II11. Among them, the tension ring I5 is set on the load-bearing ring I6, and is welded together with the front plug 3, the load-bearing ...

Abstract

The invention discloses an umbrella-type inner support clamp for annular welding of small-diameter cylindrical workpieces and solves the problems of poor welding straightness accuracy and low processing efficiency of workpieces with weld joints located at the center of the elongated cylindrical workpieces or far away from two ends of the elongated cylindrical workpieces. During use, a force-bearing nut and a front plug control a sleeve II and a sleeve I to move back and forth relative to a spindle, the sleeve II and the sleeve I control a base II and a base I to move back and forth, a supporting leg I and a supporting leg II drive a supporting leg III and a supporting leg IV to act to tightly hold a holding assembly, and accordingly the welding joint portion of the workpieces is held tight and circular. An umbrella-type inner support is not demounted during welding so that welding time is saved. The workpieces are restrained and cannot deform easily during welding due to the holding force of the umbrella-type inner support clamp, and accordingly straightness accuracy of the welded workpieces is improved and local welding collapsing deformation is reduced. The umbrella-type inner support clamp has the advantages of being convenient to operate, high in production efficiency, high in accuracy after parts are welded, wide in application range and the like, and is good in application effect.

Description

technical field [0001] The invention relates to an auxiliary part of welding equipment, in particular to an inner support fixture for circumferential welding of a cylindrical workpiece with a small diameter. Background technique [0002] The welding seam is located in the center of the slender cylindrical workpiece or the workpiece is far away from the two ends of the workpiece. In China, the outer clamp assembly, tack welding, removal of the outer clamp, and welding are generally adopted in China. After the outer clamp is assembled and tack welded, the outer clamp is removed for welding, and there are problems such as poor straightness of the workpiece and low processing efficiency. In order to solve these problems, we have designed an umbrella-shaped inner support fixture for circular seam welding. The fixture is easy to operate, has a wide range of applications, and has good application effects. Contents of the invention [0003] The technical problem to be solved by t...
