Abstract
The invention discloses a portable pneumatic spot welding machine, comprising a spot welding machine body, a gun-type body and a nib-type welding electrode, wherein an electromagnetic valve air outlet on the spot welding machine body is connected with a welding electrode air inlet at a joint between a gun handle and a gun rod by a plastic hose; the welding electrode air inlet supplies pressured air through an air source; a power output terminal on the spot welding machine body is connected with a welding electrode terminal on the lower end of the gun handle by a lead; a press-type spot welding trigger which is a touch trigger is installed on a triggering position of the gun-type body; and when the trigger is pressed down, the supplied pressured air flows into a pressure cavity of a piston component to drive the welding electrode to tightly compress and weld a thin sheet to be welded in a travelling range of the welding electrode. The pneumatic spot welding device of the invention not only solves the problem that the welding pressure controlled by manual operation is easy to cause sparkles and the welding quality consistency is poor, and realizes comfort and convenience of operation, but also greatly improves working efficiency.
Description
Technical field
The invention belongs to welding field, be specifically related to a kind of sheet metal (plate) that is directed against and carry out the overlap resistance spot welding device.
Background technology
Spot welding is simple and easy to do, the cost-effective method of a kind of connection sheet metal (plate) as an important branch of welding procedure, is widely used in fields such as Aeronautics and Astronautics, electronics, automobile, becomes one of a kind of indispensable industrial manufacturing technology.
In recent years; Development along with power technology and digitizing technique; Various novel point welding machines continue to bring out; For example inverter formula, capacitance energy storage type, ultrasonic wave metal point welding machine, digitised points welding machine or the like, however the improvement of these mash welders concentrate on mostly in discharge type and the control system, less relatively for the improvement of the operation comfort of mash welder and convenience.
At present, although various portable point welding machines and pneumatic mash welder are also arranged on the market, be that cost reduces volume and weight often to reduce power for the consideration of portability, welding pressure need manually apply; And pneumatic function is mainly used in bigger mash welder, lacks deeply taking all factors into consideration and integrate for the two.In addition, welding electrode is as the executing agency of mash welder, the parts of operator's direct control just, and producer does not often provide, and perhaps is a simple copper rod and a copper coin, lacks the design for this respect.
Therefore, in order to satisfy demands such as portable for mash welder, that operation is comfortable simultaneously, designing and invent a kind of portable pneumatic mash welder has actively and realistic meanings.
Summary of the invention
The object of the present invention is to provide a kind of portable pneumatic device of realizing sheet metal (plate) joint welding; Be intended to solve the problem of carrying out resistance spot welding under the limited situation of working space; Design a kind of new type of welding electrode simultaneously, promoted operator's comfortableness and convenience.
A kind of portable pneumatic mash welder; Comprise mash welder main frame and the rifle type main body that the mash welder main frame is set; Rifle head position is provided with a pair of middle nib type welding electrode that constitutes stroke section, is provided with piston component near the non-welding ends of welding electrode, and piston component includes pressure chamber; Wherein, Magnetic valve gas outlet on the mash welder main frame couples together through plastic flexible pipe with the welding electrode gas access that is arranged on pikestaff and barral of a gun junction, and the welding electrode gas access has infeeded pressed gas through source of the gas, through lead power output wiring terminal on the mash welder main frame and the welding electrode binding post that is arranged on the pikestaff lower end is coupled together; The spot welding trigger that the trigger position of rifle type main body also is provided with push type promptly touches trigger; With when pressing trigger, the pressed gas that infeeds gets into the pressure chamber of piston component, drives welding electrode the thin slice to be welded that is arranged in the welding electrode stroke section is compressed and welds.
Pneumatic spot welding device provided by the present invention; In the work of spacecraft thermal vacuum test infrared heating cage Denso, obtained application; The result shows: this device has not only solved the problem that the manual grasp of welding pressure causes spark and point quality uniformity difference easily; Comfortableness of controlling simultaneously and convenience, the advantage that shows under the situation about especially being restricted for the certain operations space obtains operator's approval, and operating efficiency also is greatly improved.

The specific embodiment
Below in conjunction with accompanying drawing portable pneumatic mash welder of the present invention is further described.
As shown in Figure 1; Portable pneumatic mash welder of the present invention comprises rifle type main body; And be arranged on the common on the market a kind of Portable AC mash welder main frame in the rifle type main body, and specifically, portable pneumatic mash welder of the present invention; Comprise mash welder main frame and the rifle type main body 1 that the mash welder main frame is set; Rifle head position is provided with a pair of middle nib type welding electrode 3 that constitutes stroke section, is provided with piston component 2 near the welding electrode 3 non-welding ends, and piston component 2 includes pressure chamber; Wherein, Magnetic valve gas outlet on the mash welder main frame couples together through plastic flexible pipe with the welding electrode that is arranged on pikestaff and barral of a gun junction 3 gas accesses 4, and welding electrode gas access 4 has infeeded pressed gas through source of the gas, through lead power output wiring terminal on the mash welder main frame and the power supply binding post 5 that is arranged on the welding electrode of pikestaff lower end is coupled together; The spot welding trigger that the trigger position of rifle type main body also is provided with push type promptly touches electrode trigger 6; With when pressing trigger, the pressed gas that infeeds gets into the pressure chamber of piston component 2, drives 3 pairs of thin slices to be welded that are arranged in the welding electrode stroke section of nib type welding electrode and compresses and weld.
During welding, thin slice to be welded (plate) is vertically put into the stroke section of welding electrode 3, touch trigger 6; Welding main frame magnetic valve is opened under circuit control, and source of the gas gas gets in the pressure chamber of piston component 2, drives welding electrode 3 and compresses test specimen; Through after the certain time-delay; The welding main frame is exported certain power welding current, and test specimen to be welded is accomplished welding under the function of current, and workflow is as shown in Figure 2.
Although the preceding text specific embodiments of the invention has given to describe in detail and explanation; But what should indicate is; We can carry out various equivalences to above-mentioned embodiment according to conception of the present invention and change and modification; When the function that it produced does not exceed spiritual that specification and accompanying drawing contain yet, all should be within guarantor's expansion scope of the present invention.
