Abstract
The utility model discloses a kind of anti-spilled laser weld joint structures.Including connector and pipe, connector rear end is provided with hole, pipe front end is inserted into hole, hole is welding cylindrical surface and anti-spilled cylindrical surface respectively from inside to outside, chamfering is set between anti-spilled cylindrical surface and the inside edge in outer end of hole face, anti-spilled cylindrical surface diameter is bigger than welding cylindrical surface diameter, and passes through chamfered transition between anti-spilled cylindrical surface and welding cylindrical surface.The utility model effectively prevents the problem of presentation quality decline caused by welding melting charge overflows.The contact area for increasing connector and pipe way simultaneously, reduces adverse effect of the tube vibration to welding position.
Description
Technical field
The utility model relates to a kind of laser weld joints, in particular to a kind of anti-spilled laser weld joint knot
Structure.
Background technique
In the production process using the clutch oil pipe of plastic material, connector is connected to one by laser welding with pipe way
It rises.During the welding process, it since relatively tightly and after laser irradiation tube fuse expands pipe and joints fit dimension, is connect in welding
Head-tail has melting charge spilling, is deposited between pipe and joints, affects the weld appearance quality of the two.
Utility model content
In order to solve the problems, such as background technique, the utility model provides a kind of anti-spilled laser weld joint knot
Structure makes the melting charge overflowed be filled in pipe by the way that anti-spilled cylindrical surface is arranged between fitting end chamfering and welding cylindrical surface
It is sub between anti-spilled cylindrical surface, can effectively solve welding melting charge overflow caused by presentation quality decline the problem of
In order to solve the above technical problems, the utility model adopts the following technical solution:
The utility model includes connector and pipe, and connector rear end is provided with hole, and pipe front end is inserted into hole, and hole is from inside to outside
It is welding cylindrical surface and anti-spilled cylindrical surface respectively, chamfering is set between anti-spilled cylindrical surface and the inside edge in outer end of hole face, prevents
It is bigger than welding cylindrical surface diameter to overflow cylindrical surface diameter, and pass through chamfering mistake between anti-spilled cylindrical surface and welding cylindrical surface
It crosses.
The connector is process using plastic material by Shooting Technique.
The connector and pipe is all made of plastics PA12 material.
Welding cylindrical surface in the nipple orifice and between tube outer wall use laser welding so that between connector and pipe
It is fixedly connected.
The beneficial effects of the utility model are:
The anti-spilled laser weld joint of the utility model can effectively avoid welding melting charge from overflowing under caused presentation quality
The problem of drop；The contact area for increasing connector and pipe way simultaneously, reduces adverse effect of the tube vibration to welding position.
Detailed description of the invention
Fig. 1 is the joint structure cross-sectional view of the utility model.
Fig. 2 is the welding schematic diagram of the utility model connector and pipe.
In figure: a, welding cylindrical surface, b, anti-spilled cylindrical surface, c, chamfering, 1, connector, 2, pipe.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
As shown in Figure 1, the utility model includes connector 1 and pipe 2,1 rear end of connector is provided with hole, and 2 front end of pipe is inserted into
Kong Zhong, hole are welding cylindrical surface a and anti-spilled cylindrical surface b, anti-spilled cylindrical surface b respectively from inside to outside for accommodating laser welding
Chamfering c, anti-spilled cylindrical surface b is arranged in the melting charge material generated afterwards between anti-spilled cylindrical surface b and the inside edge in outer end of hole face
Diameter is bigger than welding cylindrical surface a diameter, and passes through chamfered transition between anti-spilled cylindrical surface b and welding cylindrical surface a.
Laser welding is used between 2 outer wall of welding cylindrical surface a in 1 hole of connector and pipe, so that between connector 1 and pipe 2
It is fixedly connected.Specific implementation process is:
Before welding, pipe 2 is pre-loaded into 1 bottom of connector, pipe 1 is contacted with welding cylindrical surface a, anti-spilled cylindrical surface b with
There are gaps between pipe 2.When welding, laser beam irradiates from top to bottom and the movement that takes the air line, the work of connector 1 and pipe 2 in fixture
It is rotated under, to be formed by interior welding process outward, in the process, laser penetration connector 1 is radiated at pipe
Fusion welded zone is formed on sub 2 surfaces, extra melting charge material can squeeze out outward, can finally be filled into anti-spilled cylindrical surface b and pipe
Between son 2, it will not be overflowed from fitting end.
The anti-spilled laser weld joint of the utility model effectively prevents under presentation quality caused by welding melting charge overflows
The problem of drop.The contact area for increasing connector and pipe way simultaneously, reduces adverse effect of the tube vibration to welding position.
