Description
Technical field
The utility model relates to welding technology field, particularly relates to a kind of spot welding head.
Background technology
Spot welding head is the important precise part of electric automatic spot welding equipment, by two symmetries and the electrode of mutually insulated form, described electrode has from top to bottom: load segment, for spot welding head is assemblied in electric automated weld unit; Heating section, after two electrifying electrodes, this part produces heat, higher the closer to lower temperature.The lower end of two electrodes links together, and form spot welding section, the electric current that electrode flows through makes spot welding section have higher temperature, waits for welding assembly, make it heat firm welding for contacting, crimping such as enamel-covered wire in pinpoint welding procedure.
In order to improve the accuracy of electric automatic spot operation, need the temperature of Measurement accuracy and the described spot welding section of control.In prior art, the temp.-sensing wire of temperature-sensing device is connected to described electric welding section by the mode of welding, the temperature of spot welding section can be obtained real-time and accurately, accurately to control.
But; in the occasion that some need spot welding section to have larger heating power could to weld, the temperature of spot welding section is higher, because the tolerant temperature of tie point institute being connected to the temp.-sensing wire of spot welding section is limited; temp.-sensing wire often can be caused to come off from spot welding section, and temperature-sensing device cannot work.
Utility model content,
The technical problems to be solved in the utility model is to overcome in background technology when spot welding section temperature is higher, and the temp.-sensing wire tie point that temperature-sensing device is connected in spot welding section holds caducous defect.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of spot welding head is provided, there is the main body of little en plaque, described main body is divided into load segment, heating section, spot welding section from top to bottom, described load segment and heating section are cut from centre, form two electrodes of left and right insulation, described spot welding section connects as one, and in described heating section, is connected with temperature-sensing device.
Further, the part of cutting in the middle of described heating section is upside-down triangle shape, and the inner side of described heating section the right and left has symmetrical inwardly giving prominence to but the jut of mutually insulated respectively, and described temperature-sensing device is connected on described jut.
Further, described temperature-sensing device is connected on one of them jut.
Further, described jut has through hole or blind hole, described temperature-sensing device is connected in described through hole or blind hole, and is welded and fixed.
Further, described heating section the right and left is respectively and extends more and more narrow structure from described load segment to the direction of described spot welding section.
The beneficial effects of the utility model are: at Measurement accuracy with the while of controlling spot welding section temperature, the tie point of temperature-sensing device is connected firmly, durable in use
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of spot welding head embodiment of the utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See Fig. 1, the spot welding head of the present embodiment, has the main body 1 of little en plaque, and described main body 1 is divided into load segment 2, heating section 3, spot welding section 4 from top to bottom, and described load segment 2 and heating section 3 are cut from centre, form two electrode a and b of left and right insulation.Described load segment 2 is for being assemblied in electric automated weld unit by spot welding head main body 1, and described heating section 3, produces heat after two electrode a, b energisings, higher the closer to spot welding section 4 temperature.Described spot welding section 4 connects as one, and when spot welding head works, this part produces higher temperature, crimps workpiece to be welded, such as enamel-covered wire, will wait that produced heat is by the melts soldering tin on work piece interface to be welded, firm welding.
In described heating section 3, temperature-sensing device 7 is connected with by temp.-sensing wire 6, by measuring the temperature of certain tie point in heating section, by repeatedly testing the corresponding relation obtaining this tie point temperature and spot welding section temperature, thus just can accurately can control the temperature of spot welding section by the temperature measuring this tie point.Also the corresponding relation of this tie point temperature and spot welding section temperature can be obtained by the method for thermodynamic analysis.
Due to spot welding head work time, the temperature of heating section 3 is lower than the temperature of spot welding section 4, when needs spot welding head 4 needs high-power heating, the tie point connecting temp.-sensing wire 6 only needs the temperature of tolerance heating section 3 and does not need to tolerate the temperature of spot welding section 4, therefore tie point is not easy to come off, can durable.
Preferably, the part of cutting in the middle of described heating section 3 is upside-down triangle shape, has larger space compared with the cut in the middle of load segment 1, and such structure makes heating section 3 have larger resistance relative to load segment 4, so that when electric current is by electrode a, b, produce heat in heating section 3.
Preferably, described heating section 3 the right and left is respectively and extends more and more narrow structure from described load segment 2 to the direction of described spot welding section 4, makes on above-mentioned bearing of trend, and the resistance of heating section 3 is increasing, and temperature is more and more higher.
Preferably, the inner side of described heating section 3 the right and left has symmetrical inwardly giving prominence to but the jut 5 of mutually insulated respectively, and the jut 5 on the right connects temperature-sensing device 7 by temp.-sensing wire 6.Also on the jut of the right and left, temp.-sensing wire can be set respectively, connect temperature-sensing device 7.
The tie point of temp.-sensing wire is arranged on described jut 5, be due to relative to tie point is arranged at heating section 3 other positions, such structure is less for the Resistance Influence of heating section 3, negligible, in order to avoid the heat conductivility of impact heating section 3, make the heat conduction of heating section 3 the right and left uneven, thus strengthen the difficulty of the corresponding relation obtaining temp.-sensing wire tie point temperature and spot welding section temperature.The inner side of heating section 3 the right and left has symmetrical inwardly giving prominence to but the jut 5 of mutually insulated respectively, further reduces the impact connecting temp.-sensing wire and cause heating section 3 the right and left heat conductivility.
Preferably, the jut 5 of described the right and left is semicircle, can save the space of the middle cut-away portions of heating section 3, be convenient to processing.
Preferably, described jut 5 has through hole 8, the temp.-sensing wire 6 of described temperature-sensing device 7 is connected in described through hole or blind hole, and is welded and fixed.Described through hole also can change blind hole into.The tie point of temp.-sensing wire 6 is welded in hole, can make to connect more firm, thus more durable.
The above is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
