Abstract
The utility model discloses a spot welding head device of a spot welding machine. The utility model is characterized in that the utility model comprises a central shaft, a sleeve, a welding head, a cam plate and a cam which is driven by a motor; the sleeve is fixedly arranged on the spot welding machine; the cam is independently arranged below the cam plate; the distance from the bottom surface of the cam plate to the central shaft of the cam is more than the minimum radius of the cam; the distance from the bottom surface of the cam plate to the central shaft of the cam is less than the maximum radius of the cam; the upper end of the central shaft is fixedly connected with the cam plate; the lower end of the central shaft coaxially passes through the sleeve and is then fixedly connected with the welding head; an elastic adjusting mechanism is arranged between the sleeve and the central shaft; the spot welding head device has the advantages that the structure is simple; furthermore, when the minimum radius of the cam faces upwards, a clearance is remained between the cam plate and the cam so as to lead the welding head and the welding part to be in a normal-close state; pressure of the welding head acted on a welding part can be adjusted by only adjusting the pressure of a spring by adjusting an adjusting nut which is arranged at the upper end of the sleeve, thus ensuring the welding quality and the welding efficiency of the welding part.
Description
Technical field
The utility model relates to a kind of mash welder, especially relates to a kind of spot welding head apparatus of mash welder.
Background technology
Development along with society, people require more and more higher to sensitivity, microcosmic and the aesthetic property of electronic product, thereby the welding that causes carrying out on the plate tiny device is increasing, go up the welding of luminous tungsten filament etc. as the tiny electronic device of welding on electronic circuit board, various household electrical appliance (as video disc player, power amplifier etc.).Domestic traditional mash welder all is to work under the state of single station at present, it is the welding that welding electrode all can only be finished a solder joint when switching at every turn, and since when welding soldering tip act on the weldment rigidly, the pressure that causes being applied on the weldment is difficult for adjusting, cause the damage of weldment or soldering tip easily, be unfavorable for high efficiency, high quality welding.
Summary of the invention
Technical problem to be solved in the utility model provides the spot welding head apparatus of the mash welder of a kind of energy high efficiency, high-quality welding.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of spot welding head apparatus of mash welder, it comprises central shaft, sleeve, soldering tip, lobe plate and by motor-driven cam, described sleeve is fixedly installed on the mash welder, described cam independently is arranged on the below of described lobe plate, the bottom surface of described lobe plate is to the distance of the central shaft of the described cam least radius greater than described cam, the bottom surface of described lobe plate is to the distance of the central shaft of the described cam maximum radius less than described cam, fixedly connected with described lobe plate in the upper end of described central shaft, the lower end of described central shaft is coaxial to be passed described sleeve and fixedlys connected with described soldering tip, is provided with elastic adjusting mechanism between described sleeve and the described central shaft.
Described elastic adjusting mechanism comprises coaxial spring and the spacer that is set on the described central shaft, described central shaft is provided with positioning boss, described spacer apical grafting is on described positioning boss, be provided with the gap between the bottom surface of described spacer and described sleeve, the upper end of described sleeve is provided with the adjustment nut, and described spring apical grafting is between described spacer and described adjustment nut.
Be provided with briquetting between described adjustment nut and the described spring, described spring apical grafting is between described briquetting and described spacer.
Described central shaft and described soldering tip interconnect by gripping sleeve.
Compared with prior art, the utility model has the advantages that simple in structure, and when the least radius of cam up the time, leave the gap between lobe plate and the cam, make soldering tip and weldment be in normally off, this moment is as long as the adjusting nut that is arranged on sleeve upper end by adjusting is adjusted the pressure of spring, just can adjust soldering tip and be applied to pressure on the weldment, soldering tip is flexibly acted on the weldment, guaranteed that soldering tip and weldment are not damaged, thereby guaranteed the welding quality and the welding efficiency of weldment, and when the maximum radius of cam up the time, cam will the jack-up lobe plate, and lobe plate lifts central shaft simultaneously, makes the disconnection of soldering tip and weldment; In addition, between adjustment nut and spring, be provided with briquetting, guaranteed the stationarity when spring is adjusted, and central shaft is connected the convenient soldering tip of changing at any time by gripping sleeve with soldering tip.
