Background technology
Laser welding is widely used to household electrical appliances, automobile, machinery, electronics and light industry because welding deformation is small, precision is high now
Product manufacturing.Important component of the laser welding head as laser welding apparatus, but since welding process medium temperature spends height very
The focus lamp damage being easy to cause in laser welding head, or focusing is damaged due to welding slag splashing and the pollution of metal vapors
Mirror, to influence the service life of laser welding head.
Invention content
In view of this, it is necessary to provide a kind of laser welding heads can be well protected condenser.
The technical solution adopted in the utility model：A kind of laser welding head, including a plumb joint main body, a welding bonnet body
With a protection cap, the plumb joint body outer wall is provided with external screw thread, and the welding bonnet body inner wall is provided with and the outer spiral shell
The matched internal thread of line, the plumb joint main body are bolted in the welding bonnet body and spiral can move up and down, the guarantor
Protecting cover is arranged in the plumb joint lower body, and condenser is provided in the plumb joint main body, is opened on the welding bonnet body
Equipped with a laser light incident hole, a bellmouth is offered in the protection cap, and multiple air flues are provided in the protection cap side wall, it is more
A air flue, which is evenly arranged and is open along the surrounding of the bellmouth, extends to the protection cap lower face, the protection cap side
Cyclic water channel is additionally provided in wall, the cyclic water channel both ends are connected separately with a water inlet pipe and an outlet pipe.
The beneficial effects of the utility model are：By the setting of cyclic water channel, it can be passed through cooling water in the welding process,
The temperature for controlling laser welding head, avoids the excessively high damage condenser of temperature, while by the setting of multiple air flues, in welding process
In be passed through protective gas, form an outside air-flow and blow away welding slag and metal vapors, it is avoided to touch condenser and lead
The damage for causing condenser, to extend the service life of laser welding head.
Description of the drawings
Fig. 1 show the structural schematic diagram of laser welding head in the utility model.
Specific implementation mode
The utility model is further described below in conjunction with attached drawing, example is served only for explaining the utility model, and
It is non-to be used to limit the scope of the utility model.
As shown in Figure 1, for a kind of laser welding head in the utility model comprising a plumb joint main body 1, a plumb joint
Lid 2 and a protection cap 3,1 outer wall of plumb joint main body are provided with external screw thread, 2 inner wall of welding bonnet body be provided with
The matched internal thread of external screw thread, the plumb joint main body 1 are bolted in the welding bonnet body 2 and spiral can move up and down
Dynamic, the protection cap 3 is arranged in 1 lower end of plumb joint main body, and condenser 4, the weldering are provided in the plumb joint main body 1
A laser light incident hole 5 is offered on connector lid 2, offers a bellmouth 6 in the protection cap 3, in 3 side wall of the protection cap
Multiple air flues 7 are provided with, multiple air flues 7, which are evenly arranged and are open along the surrounding of the bellmouth 6, extends to the protection
3 lower face of lid, is additionally provided with cyclic water channel 8 in 3 side wall of the protection cap, 8 both ends of the cyclic water channel be connected separately with one into
Water pipe 9 and an outlet pipe 10.
Further, in order to preferably protect the condenser 4, one is also detachably provided in the plumb joint main body 1
Protective glasses 11, the protective glasses 11 are set to the lower section of the condenser 4, after prolonged use, if the protective glasses 11 by
The protective glasses 11 then need to only be removed replacement by pollution.
Further, in order to ensure blowing effect, the quantity of the air flue 7 is at least four, and is distributed in the taper
6 surrounding of hole ensures that the four direction in 6 lower end of the bellmouth has outside air-flow.
Further, in order to ensure water-cooled effect, the cyclic water channel 8 is around 6 screw arrangement of the bellmouth, with abundant
Increase water cooling area.
The operation principle of the utility model：In use, the plumb joint main body 1 is first screwed onto the welding bonnet body 2
On, the protection cap 3 is arranged in 1 lower end of plumb joint main body, the laser that then laser generator is sent out is via the weldering
The laser light incident hole 5 on connector lid 2 is injected, then after being focused via the condenser 4, eventually by the protection cap 3
The interior bellmouth 6 projects progress laser welding and is passed through protective gas shape via multiple air flues 7 in the welding process
The welding slag and metal vapors that welding generates are dispelled at air-flow, while cooling water is passed through via the water inlet pipe 9, cooling water enters
The cyclic water channel 8 carries out water cooling and is finally discharged by the outlet pipe 10, to control the temperature of the laser welding head so that
Temperature is unlikely to excessively high and damages the condenser 4.Before welding, also the plumb joint main body 1 can be adjusted according to actual conditions
The depth in the welding bonnet body 2 is screwed in, to control the distance arrived between the condenser 4 and the laser light incident hole 5,
To ensure best welding effect.
The beneficial effects of the utility model are：By the setting of cyclic water channel, it can be passed through cooling water in the welding process,
The temperature for controlling laser welding head, avoids the excessively high damage condenser of temperature, while by the setting of multiple air flues, in welding process
In be passed through protective gas, form an outside air-flow and blow away welding slag and metal vapors, it is avoided to touch condenser and lead
The damage for causing condenser, to extend the service life of laser welding head.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
