Description
Technical field
The utility model relates to electrode holders detection field, and particularly electrode holders electrode pressure detects accessory.
Background technology
In automobile making technique, for obtaining stable resistance spot welding quality, need this parameter of butt welding tongs electrode pressure to detect at present.Conventional detection method has two kinds: 1, by the input air pressure of monitoring soldering turret, i.e. and the pressure of Compressed Gas, indirect judgement soldering turret pressure, for example: when input compression gas-pressure is at 0.4～0.6MPa, indirect judgement soldering turret pressure is in allowed band.2, directly monitor pressure between soldering turret electrode.For example, obtain the actual value of soldering turret electrode pressure by the measurement (: 1 time/week) of certain frequency, and contrast with pressure criteria, in time deviation is revised.Concrete detection method is that the pressure sensor of pressure-measuring device is placed on the fixed electrode (bottom electrode) of soldering turret, closes energising, presses soldering turret Action Button, and float electrode is forced into the surface of pressure-measuring device, and pressure sensor obtains force value.Two kinds of control methods respectively have shortcoming, the wherein pressure of method 1 between can not direct-detection electrode, and error is very large.And although method 2 can directly record the pressure between electrode; but the end face of electrode end surface and pressure sensor is all very little; float electrode (top electrode) presses down the phenomenon that often there will be malposition of electrode in process; once electrode misplaces; the sensor of pressure-measuring device will be distorted between upper and lower electrode, causes the connective pole of sensor to fracture, and very easily build-up of pressure measuring instrument damages; maintenance cost is quite high, approximately 20,000 yuan of single maintenance costs.And dislocation between electrode easily to cause electrode to produce bending, the service life of reducing soldering turret.
Summary of the invention
The purpose of this utility model is to provide a kind of electrode holders electrode pressure for fixation pressure measuring instrument and detects accessory.
For achieving the above object, the utility model has adopted following technical scheme: a kind of electrode holders electrode pressure detects accessory, comprise for being set in the sleeve on bottom electrode bar, between this sleeve and bottom electrode bar, be provided with fastening unit, described sleeve is provided with shoulder hole, the large aperture section of shoulder hole is set on bottom electrode bar, and lower electrode tip is positioned at the small-bore section of shoulder hole.
Owing to adopting above technical scheme, sleeve is fixed on bottom electrode bar, pressure-measuring device is placed on lower electrode tip, lower electrode tip and pressure-measuring device are positioned at small-bore section, sleeve carries out spacing to pressure-measuring device, even misplace between upper/lower electrode, pressure-measuring device also can not drop, effectively avoid pressure-measuring device to damage, reduce testing cost.
