Description
Technical field
The invention belongs to hydraulic fittings technical field, and specifically, the present invention relates to a kind of welding of wavy metal tube end
Flange positioner.
Background technology
Need to use metal bellows in the connection procedure of fluid pressure line, in metal bellows connection procedure, it is necessary to
In wavy metal tube end welding flange, but current welding flange is all artificial first spot welding, is then continuously being welded,
The size disparity of metal bellows both ends ring flange is larger after welding, the poor consistency of product, causes to pacify in fluid pressure line
Air-tightness bad control during dress, influences the normal work of fluid pressure line.
The content of the invention
The present invention provides a kind of wavy metal tube end welded flange positioner, realizes metal wave under the state of being sized
The welding operation of line pipe and ring flange, ensure that the uniformity of the size after welding.
To achieve these goals, the technical solution taken of the present invention is：A kind of wavy metal tube end welded flange is determined
Position device, including base, lower seat board, screw rod, upper base plate, platform nut, stop nut, locking nut and graduated scale, under described
Seat board is connected by bolt with base, and the screw rod lower end is connected with lower seat board, and the screw rod upper end passes through upper base plate, described flat
Platform nut and stop nut are screwed on screw rod, and the platform nut adjusts height of the upper base plate on screw rod, is then locked
Nut pins, and the graduated scale lower end is connected with base, and graduated scale is perpendicular to base.
Preferably, the platform nut is equipped with supporting plate.
Preferably, the graduated scale is " L " type.
Preferably, the graduated scale is steel ruler.
It is using the beneficial effect of above technical scheme：The wavy metal tube end welded flange positioner, is being welded
Before, first metal bellows is placed on lower seat board, is then gone to twist platform nut with spanner, the ring flange welded according to both ends it
Between size, according to graduated scale adjust upper base plate to suitably sized position, then locked by stop nut, then treat upper base plate
Position adjust it is fixed after, ring flange to be welded is bolted with upper base plate, then again by metal bellows and method
Blue disk welds together, and realizes the welding operation of metal bellows and ring flange under the state of being sized, it is therefore prevented that welding deformation,
It ensure that the uniformity of the size after welding.
The platform nut is equipped with supporting plate, ensure that platform nut support lives in the stability and levelness of seat board, avoids
There is the ring flange end slope welded；The graduated scale is " L " type, facilitates the installation of graduated scale；The graduated scale is steel
Ruler, avoids being worn and welds the bright erosion of arc light.

Embodiment
Below against attached drawing, by the description of the embodiment, making to embodiment of the invention further details of
Explanation, it is therefore an objective to help those skilled in the art to have more complete, accurate and deep reason to design of the invention, technical solution
Solution, and contribute to its implementation.
As shown in Figure 1 to Figure 2, the present invention is a kind of wavy metal tube end welded flange positioner, realizes scale
The welding operation of metal bellows and ring flange, ensure that the uniformity of the size after welding under very little state.
Specifically, as shown in Figure 1 to Figure 2, it is including base 1, lower seat board 2, screw rod 3, upper base plate 4, platform nut 5, anti-
Loose nut 6, locking nut 7 and graduated scale 8, the lower seat board 2 are connected by bolt with base 1,3 lower end of screw rod and lower seat
Plate 2 connects, and 3 upper end of screw rod passes through upper base plate 4, and the platform nut 5 and stop nut 6 are screwed on screw rod 3, and described flat
Platform nut 5 adjusts height of the upper base plate 4 on screw rod 3, and the nut 7 that is then locked pins, 8 lower end of graduated scale and base 1
Connection, and graduated scale 8 is perpendicular to base 1.
As shown in Figure 1, the platform nut 5 is equipped with supporting plate 50.
As shown in Figure 1 and Figure 2, the graduated scale 8 is " L " type.The graduated scale 8 is steel ruler.
Specific working mode is illustrated with specific embodiment below：
The wavy metal tube end welded flange positioner, before welding, is first placed on lower seat board by metal bellows 9
On 2, then gone to twist platform nut 5 with spanner, the size between the ring flange 10 welded according to both ends, is adjusted according to graduated scale 8
Upper base plate 4 arrives suitably sized position, is then locked by stop nut 6, will after then adjusting and fix after the position of upper base plate 4
Ring flange 10 to be welded is bolted with upper base plate 4, and metal bellows 9 and ring flange 10 then are welded on one again
Rise, realize the welding operation of metal bellows and ring flange under the state of being sized, it is therefore prevented that welding deformation, after ensure that welding
Size uniformity.
The platform nut 5 is equipped with supporting plate 50, ensure that platform nut 5 holds the stability and levelness of upper base plate 4,
Avoid the occurrence of 10 end slope of ring flange of welding；The graduated scale 8 is " L " type, facilitates the installation of graduated scale；The scale
Ruler 8 is steel ruler, avoids being worn and welds the bright erosion of arc light.
The present invention is exemplarily described above in association with attached drawing, it is clear that the present invention implements and from above-mentioned side
The limitation of formula, as long as employ the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress；Or not
It is improved, the above-mentioned design of the present invention and technical solution are directly applied into other occasions, in protection scope of the present invention
Within.
