Abstract
The utility model relates to the field of welding assembly electrode holder equipment, in particular to a water-cooled single-side spot welding gun, which comprises an electrode stem arranged at the front end of a hollow gun body. A water inlet way and a backwater way communicated with the water inlet way are arranged in a cavity inside the gun body. The communication portion is arranged at the front end of the gun body. The water inlet way and the backwater way are both connected with a water tank. High pressure cooling water flows into the water inlet way through a water inlet, flows into the backwater way to form a circulation water way, and then discharges out of the gun body through a water outlet and returns to the water tank. The heat generated by the welding gun during use is absorbed continuously by the circulation cooling water, thereby lowering the temperature of the electrode stem, effectively avoiding the problems of sticking to a plate and weld penetration, realizing the continuous use of the spot welding gun, ensuring the welding quality, and improving the working efficiency.
Description
Technical field
The utility model relates to the soldering turret apparatus field that is welded, particularly water-cooled indirect welding welding gun.
Background technology
The indirect welding welding gun when welded blank because temperature is high easily bonding with sheet material to be welded, if untimely cooling is prone to problems such as burn-through, mostly the spot-welding gun that uses is to adopt air-cooled cooling or cooling naturally at present, cooling effect is poor, obviously blackout and regular being bonded on the plate to be welded of electrode when continuous welding reaches 20 above solder joints, can't in time peel off even burn plate, therefore cause welding gun long-time continuous not use, influence operating efficiency.
Summary of the invention
The purpose of this utility model provides a kind of good cooling results, the water-cooled indirect welding welding gun that can use continuously.
For achieving the above object, the utility model has adopted following technical scheme: water-cooled indirect welding welding gun, the front end that comprises the rifle body of hollow form is provided with electrode stem, the internal cavities of rifle body is provided with water inlet road and the backwater road that is interconnected, this connection place is positioned at the front end of rifle body, and the water inlet road links to each other with backwater Lu Junyu water tank.
Owing to adopt above technical scheme, high-pressure cooling water flows into the water inlet road through water inlet, enter the backwater road afterwards and constitute circulation waterway, discharge outside the rifle body from water return outlet more afterwards and get back to water tank, the heat that welding gun in use produces is recycled cooling water and constantly absorbs, and reduces the temperature of electrode stem, effectively avoid problems such as haftplatte and burn-through to occur, realize the continuous use of spot-welding gun, guaranteed welding quality, improved operating efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view and the water route circulation schematic diagram of spot-welding gun.
The specific embodiment
As Fig. 1, a kind of water-cooled indirect welding welding gun comprises that the front end of the rifle body 10 of hollow form is provided with electrode stem 20, and the internal cavities of rifle body 10 is provided with water inlet road 13 and the backwater road 14 that is interconnected, both connections place are positioned at the front end of rifle body 10, and water inlet road 13 all links to each other with water tank with backwater road 14.Rifle body 10 in the utility model is provided with power switch 16, power switch 16 is connected with power line 19, the other end of power line 19 is connected to welding machine, rifle body 10 middle parts are provided with lock ring button 17, the handle being convenient to control 15 buckles 17 by bolt 18 is affixed with lock ring, power switch 16 is positioned on the handle 15, between lock ring button 17 and the rifle body 10 insulating barrier is set, and can effectively prevent to produce electric arc between handle 15 and the rifle body 10.During the welding gun operate as normal, high-pressure cooling water flows into water inlet road 13 through water inlet 11, enter backwater road 14 then, discharge from water return outlet 12 more afterwards and get back to water tank formation circulation waterway outside the rifle body 10, the heat that welding gun in use produces is recycled cooling water and constantly absorbs, and reduces the temperature of electrode stem 20, effectively avoid problems such as haftplatte and burn-through to occur, realize the continuous use of spot-welding gun, guaranteed welding quality, improved operating efficiency.
Described electrode stem 20 is poroid in being, connection place on water inlet road 13 and backwater road 14 is positioned at electrode stem 20.Temperature during welding on the electrode stem 20 is the highest, and the circulation of cooling water directly can be taken away a large amount of heat timely and effectively by electrode stem 20, and cooling effect is better, and is more obvious.
Described rifle body 10 is a two-layer pipe, and the nexine cavity constitutes water inlet road 13, and outer cavity constitutes backwater road 14.The recirculated cooling water of this structure rifle body 10 of flowing through can reduce the temperature of rifle body 10 timely and effectively, has reasonably arranged water inlet road 13 and backwater road 14 simultaneously, makes the cooling water circulation smooth and easy, good cooling results.
The water inlet 11 on described water inlet road 13 is positioned at end, rifle body 10 rear end, and the delivery port 12 on backwater road 14 is positioned on the rifle body 10 of water inlet end 11 sides, on the termination, rear end of the sheathed rifle body 10 of Water cooling cable.Water cooling cable is a hollow form, be set on the rifle body 10 in water inlet 11 outsides, play the water inlet pipe effect, what adopt on the Water cooling cable is the 24V safe voltage, can not produce danger, dual-purpose the simplifying the structure of one pipe, delivery port 12 is connected with the water pipe of joining water box, and high-pressure cooling water flows into water inlet road 13 from Water cooling cable, rifle body 10 is discharged from delivery port 12 in circulation cooling back, get back to water tank afterwards, the channel circulation structure in the utility model is simple, good cooling results and recycling water resource.
The head of described electrode stem 20 is arranged with removable electrode cap 21, and electrode stem 20 still has damage after long-time the use, and the sheathed electrode cap of being convenient to change 21 does not influence welding effect, and is convenient to repair and replacement, reduces use cost.
