Abstract
The utility model relates to the field of welding jigs, in particular to a finned tube welding jig. The finned tube welding jig comprises a base, two symmetrical supports are vertically arranged on the base, a pressing plate is vertically fixed to the upper portion of each support, and the two supports are respectively the fixed support and the movable support. The movable support is of an L-shaped structure formed by a longitudinal shaft and a transverse rod, the two sides of the transverse rod are in a shape like a Chinese character 'ao', a sliding way is arranged on the base, and the sliding way is provided with a protruding block and a cavity to be mounted to the two sides of the transverse rod in a slidable matching mode. The distance between the two supports are adjusted through the movable support, that is, before welding is carried out, the distance between two unthreaded tubes of the fin tubes can be adjusted flexibly according to welding requirements; unthreaded tubes of different diameters can be welded and clamped through the support with height adjustable, and the application range of the jig is widened.
Description
Technical field
The utility model relates to weld jig field, particularly a kind of extended surface tube weld jig.
Background technology
Extended surface tube is in order to reclaim station boiler, Industrial Boiler, Industrial Stoves, the smoke discharging residual heats such as Ship Power Equipment, effectively improve the utilization rate of fuel, and the enhanced heat exchange element of arranging at the cloth tail of system flue, and its Main Function is to increase heating surface (or heat radiation), improve heat transfer efficiency, as shown in Figure 1, extended surface tube is to have the steel disc 15 of circular arc to be welded together to form fin with light pipe 14 symmetrically two centres, and in welding process, what bother most is the fixing and adjustment to steel disc and light pipe welding position, the clamping of wlding, adjust inconvenient, unstable, the efficiency of capital impact welding.
Utility model content
For above-mentioned defect of the prior art, the utility model provides a kind of extended surface tube weld jig, this fixture can carry out flexibly the welding position of steel disc and light pipe, accurately, stably fixing, easy to adjust, greatly improve welding efficiency.
The utility model is achieved through the following technical solutions: comprise base; On described base, be vertically provided with two symmetrical supports, support upper vertical is fixed with pressing plate, and two supports are respectively fixed support and movable supporting frame; Described movable supporting frame forms " L " shape structure by the longitudinal axis and cross bar, and the both sides of described cross bar are " recessed " shape structure, and base is provided with slideway, and slideway is provided with projection, cavity slidably coordinates installation with described cross bar both sides.
Further, described pressing plate height is fixed on described support adjustablely; Described support is divided into outer sleeve and inner sleeve two parts, and inner sleeve is sleeved in outer sleeve, and inner sleeve outer wall is provided with the gear teeth, coordinates the gear of installing to be fixed on the window of described outer sleeve outer wall with the described gear teeth; Described pressing plate is fixed on the top of described inner sleeve.
Further, on described support, be set with spring.
Further, described pressing plate is provided with dog screw.
The beneficial effect that the utility model brings is: by movable supporting frame, regulate two distances between support, can, before welding, the distance between two of extended surface tube light pipes be adjusted flexibly by welding requirements; By height adjustable support, the light pipe that can carry out different-diameter welds clamping, has expanded the scope of application of fixture.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As the embodiment of extended surface tube weld jig described in the utility model, as shown in Figure 1, comprise base 1; On described base 1, be vertically provided with two symmetrical supports, support upper vertical is fixed with 3, two supports of pressing plate and is respectively fixed support 201 and movable supporting frame 202; Described movable supporting frame 202 forms " L " shape structure by the longitudinal axis 4 and cross bar 5, as shown in Figures 2 and 3, the both sides of described cross bar 5 are " recessed " shape structure, base 1 is provided with slideway 6, slideway 6 is provided with projection 7, cavity 8 slidably coordinates installation (as shown in Figure 4) with described cross bar both sides, movable supporting frame 202 along slideway 6 can carry out away from or near the moving of fixed support 201.Two light pipes 14 of extended surface tube are to be fixed between the pressing plate 3 of support and base 1, because the distance of two supports can be adjusted, before welding, to the distance between two of extended surface tube light pipes 14, can adjust flexibly by welding requirements, then carry out clamping, improved the efficiency of welding.
Further improve and be: described pressing plate 3 is fixed on described support highly adjustablely; As shown in Figure 5, described support is divided into outer sleeve 9 and inner sleeve 10 two parts, inner sleeve 10 is sleeved in outer sleeve 9, and inner sleeve 10 outer walls are provided with the gear teeth, coordinates the gear 11 of installing to be fixed on the window 12 of described outer sleeve 9 outer walls with the described gear teeth; Described pressing plate 3 is fixed on the top of described inner sleeve 10, by swing pinion 11, can drive inner sleeve 10 make progress or move downward, bring pressing plate 3 to the increase of base 1 distance or reduce, the welding that makes fixture can adapt to different-diameter light pipe 14 clamps, and has expanded the scope of application of fixture.
And on described support, be set with spring 12, and described pressing plate 3 is provided with dog screw 13, and the setting of Zhe Liangge mechanism has increased the steadiness of fixture clamping further, easy to operate, has guaranteed the quality of welding.
