The being welded and fixed when present invention carries out fire door circular pipe using mechanical system, ensure that fixed during welding accurate
Degree, reduces mismachining tolerance, it is to avoid welded gaps are produced, and fire door welding quality is improved, so as to ensure boiler seal, it is ensured that boiler
The efficiency of heating surface.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is structure composition schematic diagram of the invention；
Fig. 2 is top view of the invention.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, below it is right
The present invention is expanded on further.
As shown in Figure 1 to Figure 2, a kind of circular fire door fixing device used for welding of boiler, including base 1, a left side for the base 1
Right two ends are connected with riser 2, and the inner side of riser 2 at the two ends is hinged with the swing rod 3 of elastic telescopic, the end connection of swing rod 3
There is fixture block 4, the connecting rod 5 of elastic telescopic is provided between the lower end of the swing rod 3 and bottom plate 1, one end of connecting rod 5 is hinged on swing rod 3
The upper and other end is hinged on bottom plate 1, the upper end of swing rod 3 is fixed with arc 6, and arc 6 is spaced apart provided with even
It is slidably fitted with and is slidably fitted with column 8, the column 8 and through hole 7 coordinates has strong market potential 9 on through hole 7, the bottom plate 1.
In this way, circular pipe is clamped between fixture block 4, by the way that the swing rod 3 of both sides is compressed, swing rod 3 to
The lower position of circular pipe is swung there is provided the clamping force to circular pipe, by arc 6 by upper through hole 7 and column 8
Have strong market potential and 9 the position of swing rod 3 be fixed, the present invention can realize the Quick-clamped positioning of circular pipe position, adapt to regulation circle
The setting height(from bottom) of tubing, during dismounting, connecting rod 5 can also realize automatically reseting for whole device, convenient to be operated next time.
The swing rod 3 covers 32 including a bar 31 being connected with riser 2, the length being fixed on a bar 31, is slidably installed
Covered in length on 32 and connect No. two bars 33 of fixture block 4, be arranged between a bar 31 and No. two bars 33 and be located at long cover in 32
A number spring 34.In this way, clamping force of the fixture block 4 to circular pipe is provided by spring.
The connecting rod 5 includes the first bar 51 being connected with swing rod 3, the elongate sheath 52 being fixed on the first bar 51, slip peace
The second bar 53 being connected in elongate sheath 52 and with bottom plate 1, is arranged between the first bar 51 and the second bar 53 and positioned at elongated
No. two springs 54 in set 52.In this way, circular pipe is after machining, by No. two springs 54 in connecting rod 5, real
The reset of existing swing rod 3, provides swing rod 3 upward active force, moreover it is possible to play the supporting role to swing rod 3.
The through hole 7 is six and arranged on arc 6 in camber line.In this way, have strong market potential 9 from different through holes
7 coordinate, and the regulation of circular pipe in height are realized, while also acting as fixation.
The fixture block 4 is provided with V-shaped groove 41 away from the curved structure of end face and described end face being hinged with swing rod 3.Adopt
In this way, circular pipe exterior contour is catered in arcuate structure design, and when circular pipe surface, which exists, to be deformed, V-shaped groove 41 can
The clamping that Reducing distortion is brought is unstable, ensure that fixture block 4 plays more preferable fixed effect when contacting circular pipe.
The long chute 1a coordinated with column 8 is offered on the bottom plate 1.
The operation principle to the present invention is further elaborated below：
Circular pipe is placed between two fixture blocks 4, circular pipe is pressed, a bar 31 of circular pipe both sides compresses a bullet
Spring 34 a, bar 31 is slided in long set 32, and due to the effect of spring force, circular pipe is tightly clamped together by fixture block 4, will be vertical
Post 8 makes column 8 move into place in the position of the lower end of arc 6, determines the height and position of circular pipe in the enterprising line slip of bottom plate 1
Afterwards, sliding to have strong market potential 9 makes it coordinate with the through hole 7 in arc 6, so as to realize the fixation of circular pipe position, is processed welding.
After the completion of welding, the cooperation of have strong market potential 9 and through hole 7 is removed, in the presence of connecting rod 5, No. two springs 54 discharge, first
The upward sliding of bar 51, swing rod 3 is pushed up, and swing rod 3 is recovered initial position, convenient processing welding next time.
