Description

The automatic welding tooling of the girth joint of electric automobile water cooling base
Technical field
The utility model belongs to seam welding technology field, relates in particular to the automatic welding tooling of a kind of girth joint for the electric automobile water cooling base.
Background technology
Motor in electric automobile can produce heat when operation, cause each position heating of motor, when each position temperature is too high, can have a strong impact on electrical machinery life, even can bring potential safety hazard, this just need cool off motor, often adopt than the better water-cooling system of air cooling effect in the prior art, and water cooling base is the important component part in the whole water-cooling system, also is the pith that influences the water-cooled effect; The water-cooled effect of water cooling base depends on the water-cooling area of water cooling base, heat transmission, air-tightness, uniformity, this just needs to guarantee the level and smooth of the whole process of water cooling base, and is stable, evenly, wherein the welding at each position of water cooling base has also become a wherein vital ring.
In the prior art, the method for welding is that the electric automobile water cooling base is stood upright on the turntable, and the workman implements welding from the side; the welding position is horizontal position welding; welding method is semi-automatic welding, and welding quality relies on the welder to control fully, and speed of welding is slow; weld joint stable, uniformity are not enough; appearance forming is relatively poor, very easily produces weld defect and rosin joint, and welding airtightness requires and can not be guaranteed; and working strength is big, and human cost is higher.
The utility model content
Defective in view of above-mentioned prior art existence, the purpose of this utility model is the automatic welding tooling of girth joint that proposes a kind of electric automobile water cooling base, electric automobile welding quality and appearance forming requirement have been satisfied, improve solder yield and production efficiency, reduced workman's working strength and manpower production cost.
The purpose of this utility model will be achieved by the following technical programs:
The automatic welding tooling of a kind of girth joint of electric automobile water cooling base comprises that one is used for clamping device and a girth joint automatic soldering device of axial clamping workpiece to be welded; Described girth joint automatic soldering device comprises a pedestal, and described pedestal is provided with a motor, and the rotating shaft of described motor links to each other with a chuck, and described chuck axis is to clamping described clamping device; The girth joint position of described workpiece to be welded is provided with a welding gun.
Preferably, also be provided with an air valve backstop that is used for described clamping device is applied upset force on the described pedestal, described chuck, clamping device and air valve backstop same axially on.
Preferably, described clamping device comprises two grip blocks of coaxial setting in opposite directions.
Preferably, the profile of described grip block is consistent with the profile of described workpiece to be welded, and the external diameter of described grip block is greater than the external diameter 0~0.5mm of described workpiece to be welded.
The beneficial effects of the utility model are: the automatic welding tooling of the girth joint of electric automobile water cooling base of the present utility model, realized the automation welding of water cooling base, change the welding position into welding quality the most stable downhand position by horizontal position of the prior art, the welded seam quality significantly improves, internal flaw and rosin joint are few, weld joint stable and good uniformity, good looking appearance, improve solder yield and production efficiency, reduced workman's working strength and manpower production cost.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
The automatic welding tooling of girth joint of a kind of electric automobile water cooling base of present embodiment as shown in Figure 1, comprises clamping device 2 and girth joint automatic soldering device for axial clamping workpiece 1 to be welded; The girth joint automatic soldering device comprises pedestal 3, and pedestal 3 is provided with motor 4, and the rotating shaft of motor 4 links to each other with chuck 5, and chuck 5 axial clamp are gripped and held device 2; Also be provided with on the pedestal 3 for the air valve backstop 6 that clamping device 2 is applied upset force, chuck 5, clamping device 2 and air valve backstop 6 same axially on.The girth joint position of workpiece 1 to be welded is provided with welding gun 7.Clamping device 2 comprises two grip blocks of coaxial setting in opposite directions.The profile of grip block is consistent with the profile of workpiece 1 to be welded, and the external diameter of grip block is greater than the external diameter 0~0.5mm of workpiece 1 to be welded.
When using present embodiment, earlier workpiece 1 to be welded is clamped on the clamping device 2, use then chuck 5 with clamping device 2 in axial clamping, and rely on air valve backstop 6 to apply upset force at opposite side, guarantee that workpiece 1 to be welded can not slide or tilt.Welding gun 7 is fixed on the girth joint position of workpiece 1 to be welded, motor 4 starts simultaneously with the power supply of welding gun 7, rely on the rotating shaft of motor 4 to drive chuck 5, chuck 5 drives workpiece 1 to be welded and at the uniform velocity rotates, and in workpiece 1 rotation to be welded, welding gun 7 is ceaselessly treated the girth joint of welder's part 1 and filled weld metal, until rotating a week, after finishing the welding of girth joint, cut off the power supply of motor 4 and welding gun 7, finish welding.
The automatic welding tooling of girth joint of the electric automobile water cooling base of present embodiment, realized the automation welding of water cooling base, change the welding position into welding quality the most stable downhand position by horizontal position of the prior art, the welded seam quality significantly improves, internal flaw and rosin joint are few, weld joint stable and good uniformity, good looking appearance, improve solder yield and production efficiency, reduced workman's working strength and manpower production cost.
