Abstract
The utility model discloses a multifunction welding repairing machine for vehicles, which is a new welding repair machine in car repair industry. An arc welding and an electric resistance welding machines are divided into two machines in the prior art, the technology of the utility model enable the arc welding and electric resistance welding characteristics are organically combined into integration. The utility model comprises a Chinese character 'kou'-shaped iron core transformer, a transfer switch and peripheral tools. The utility model is characterized in that the secondary winding of a transformer is wound according to different sections, the end points of each of section secondary winding are respectively connected through the other transfer switch with two sets contacts, each secondary winding can be converted into a parallel connection or a serial connection, and one machine with multiple functions can be realized. The utility model can be used in mechanical working industry and is particularly suitable for car repair units.
Description
The utility model belongs to the metal welding techniques field, and particularly a kind of multi-functional welding repair machine is suitable for the vehicle maintenance industry.
Metal welding is met sb. at the airport, and generally is divided into arc-welding and electric resistance welding (or claiming Contact welding) two classes.The former requires the falling characteristic of output HIGH voltage, little electric current, the latter requires the flat characteristic of output LOW voltage, big electric current, all has a detailed description in the multiple books such as " contacting welding technology " by AC lid Germania work that " use of general arc welder and maintenance " and the Chinese industrial publishing house by the chief editor of Chengdu electric welding machine research institute that its principle is published in China Machine Press publishes.It has been generally acknowledged that it is impossible that aforementioned two kinds of output characteristic are provided on the transformer of a welding machine, thereby in the occasion of needs welding, especially vehicle maintenance unit, must dispose multiple devices such as arc welder, spot welding machine, acetylene welding set respectively, cause that welding machine quantity is many, work does not cause efficient low smoothly, and acquisition expenses height.
The purpose of this utility model is for market provides a kind of power supply that multiple output characteristic is arranged, connect supporting peripheral utensil after, have multiple welding function, vehicle Repair Welding machine simple to operate.
The utility model comprises port type iron core main transformer, change over switch, auxiliary circuit and supporting peripheral utensil, wherein change over switch connects each tap of non-leakage field winding of primary and elementary leakage field winding, the characteristics of the technical program are that secondary winding is to roll with the sheet copper segmentation, the end points that connects in addition each section secondary winding with a change over switch that two groups of contacts are arranged respectively is to change the in parallel of each section secondary winding or to connect.
Auxiliary circuit has effects such as time control, overcurrent protection, and supporting peripheral utensil selects as required and connects.
Utilize the utility model technology, can provide a kind of novel welding equipment for welding profession, it has multiple functions such as arc-welding, spot welding, butt welding, brazing, boring, soldering, side cut, heating and storage battery lead welding, and a tractor serves several purposes is in light weight, conveniently moving, the operation changing-over is simple, and maintenance can be worked under adverse circumstances easily, be suitable for engineering goods processing maintenance, especially be fit to the Mechanical Help sector application.
Accompanying drawing has been represented electrical schematic diagram of the present utility model.
Be further described below in conjunction with embodiment.With reference to accompanying drawing.Change over switch S
1Be 8 rotary switches of three terminals, N is non-leakage field winding in the elementary winding of main transformer B, and n is the leakage field winding, is tapped.Change over switch S
1Can change the connection of winding N, n tap, respectively get some from non-leakage field winding and leakage field winding, the working turns summation of these two parts is remained unchanged, the leakage reactance value of transformer will change as required, thereby reach the purpose of regulating output current.Change over switch S
2Have two groups of contacts, it can control the output of falling characteristic or flat characteristic.When being in position shown in the accompanying drawing, each section secondary winding is a tandem-type connection, becomes the arc-welding winding with falling characteristic, X
O, X
hLink for the arc-welding supporting apparatus.Change change over switch S
2During the position, each section secondary winding is parallel connection method, becomes constant potential electric resistance welding winding, X
O, X
dBe spot welding, butt welding, brazing, boring, soldering, side cut, heating and storage battery lead welding supporting apparatus link.
Supporting peripheral utensil major part is a hand-hold type, can carry out handwork.
