Cylinder locating shaft is again provided with described straight tube seat a and cylinder positioning outer shaft sleeve has straight tube.
A part for described l template is parallel with plate upper surface, and another part is vertical with plate upper surface, and inclined tube position
Inner side in l template and plate upper surface vertical component.
Described number of springs is three groups.
Described fixed block is fixed by screws in the upper surface of support base.
Described l template, straight tube seat a, straight tube seat b, support base and positioning seat are all fixed by screws in the upper table of base plate
The invention has the advantages that convenient mounting and clamping, accurate positioning, the fork-shaped of different angles can be welded, also
Bipass can be welded.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the enlarged drawing of a-a in Fig. 1；
In figure, 1 base plate, 2 l templates, 3 straight tube seat a, 4 straight tube seat b, 5 support bases, 6 positioning seats, 7 straight tubes,
8 sleeve pipes, 9 handles, 10 baffle plates, 11 cylinder locating shafts, 12 inclined tubes, 13 fixed blocks, 14 slide blocks, 15 bullets
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to described below:
As depicted in figs. 1 and 2, a kind of Y-branch fitting sealing of tube fitting device, including base plate 1, l template, straight tube seat a3, straight tube seat
B4, support base 5 and positioning seat 6, described straight tube seat a3 and straight tube seat b4 is correspondingly arranged at the left and right sides of base plate 1 upper surface,
Straight tube seat a3 is provided with cylinder locating shaft 11 on the face corresponding with straight tube seat b4, and straight tube 7 is fixed on by cylinder locating shaft 11
Between straight tube seat a3 and straight tube seat b4, straight tube seat b4 is fixed with sleeve pipe 8 in the horizontal direction, is placed with screw thread cooperation inside sleeve pipe 8
Handle 9, the two ends of handle 9 are all stretched out outside sleeve pipe 8, and handle 9 left end is fixed with block 10, and the left end of block 10 is fixed with cylinder
Locating shaft 11, handle 9 right-hand member is provided with handle, and by handle turning handle 9, handle 9 is moved to the left in rotation process and carries
Dynamic block 10 is moved to the left, it is achieved thereby that the clamping of straight tube 7；The both sides of straight tube 7 are all disposed with l template 2, support base 5
With positioning seat 6, the angle of l template 2, support base 5 and positioning seat 6 line and straight tube 7 formation Y-branch fitting pipe requirement, inclined tube 12 is put
Put in the l template 2 in straight tube 7 both sides, support base 5 and positioning seat 6 and inclined tube 12 is contacted with straight tube 7, l template 2 plays placement
Inclined tube 12 is separated in welding with straight tube 7, and the upper surface of support base 5 is provided with V-shaped groove and fixed block 13, and V-shaped groove is placed
Inclined tube 12, fixed block 13 is used for fixing inclined tube 13, fixed block 13 screw is fixed on the upper surface of support base 5, sets in positioning seat 6
It is equipped with slide block 14, between slide block 14 and positioning seat 6, be provided with three groups of springs 14, the another side relative with spring 15 in slide block 14
On be provided with cylinder locating shaft 11 and inclined tube 12 is enclosed within this cylinder locating shaft 11.
During work, first straight tube 7 is enclosed within straight tube seat a3 and the cylinder locating shaft 11 of straight tube seat b4, turns handle 9 and make
Block 10 is moved to the left, thus clamping straight tube 7；In the cylinder that the termination of two inclined tubes 12 is respectively fitted over symmetrical positioning seat 6
On locating shaft 11, by inclined tube 12 top pressure slide block 14, so that spring 15 produces to slide block 14 is in compressive state, spring 15
Inclined tube 12 is made to produce an axial force, the middle part of inclined tube 12 is placed in the V-shaped groove of support base 5, then will tiltedly with fixed block 13
Pipe 12 is pushed down, and fixed block 13 is fixed by screws in the upper surface of support base 5, and another termination of inclined tube 12 is contacted with straight tube 7,
And a radial force is produced to inclined tube 12 it is ensured that inclined tube 12 and straight tube 7 accurate positioning by l template 2, it is easy to weld.
In the present embodiment, described l template 2, straight tube seat a3, straight tube seat b4, support base 5 and positioning seat 6 are all by screw
It is fixed on the upper surface of base plate 1, when the length of straight tube 7 and inclined tube 12 changes, inclined tube 12 is become with the angle of straight tube 7
During change, realized by adjustment l template 2, straight tube seat a3, straight tube seat b4, support base 5 and positioning seat 6 position on base plate 1.
The above be only the preferred embodiment of the present invention it should be understood that the present invention be not limited to described herein
Form, is not to be taken as the exclusion to other embodiment, and can be used for various other combinations, modification and environment, and can be at this
In the described contemplated scope of literary composition, it is modified by the technology or knowledge of above-mentioned teaching or association area.And those skilled in the art are entered
