Problems solved by technology

When the automatic welding tongs are clamped, before and after the electrode cap is replaced, the welding tongs body will cause errors in clamping the workpiece, which will reduce the working efficiency of the cylinder, the output force of the cylinder is less than the theoretical calculation value, and the corresponding welding pressure is also reduced.

Abstract

The invention relates to the technical field of electrode holders, in particular to an electrode holder mold-repairing compensation device and method and an electrode holder device. When the electrodeholder mold-repairing compensation device needs to be replaced with a new electrode cap in an original state of an electrode holder, a Z-axis servo motor records a present absolute value encoder value and stores the present absolute value encoder value in an allocation data area, for example, a present figure is a first record value; after mold-repairing is completed, the Z-axis servo motor absolute value encoder value in the original state of a pneumatic electrode holder after the mold-repairing is recorded as a second record value, at the moment, the loss of the electrode cap after the mold-repairing is a third record value which is equal to the first record value minus the second record value, and a value of the third record value is transmitted to a Z-axis position value of a walkingtrack; and the lost value after mold-repairing is compensated by the Z-axis value in the original track to reach precise positioning at the Z-axis position. The electrode holder mold-repairing compensation method has the above advantages compared with the prior art. The electrode holder device has the above advantages compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of welding tongs, in particular to a welding tongs mold repairing and compensating device, a method thereof and a welding tongs device. Background technique [0002] At present, automatic welding tongs is one of the important welding equipment in the spot welding process of automobile body parts. The automatic welding tongs are generally fixedly installed on the welding fixture. After the parts are clamped, the workpiece is automatically clamped to complete the welding of a solder spot. The pressing force of welding tongs and the welding current that can be generated determine the quality of solder joints. The movement and pressure output of most types of automatic welding guns are realized by cylinders. Under the premise of a certain gas source pressure and a certain cross-sectional area of ​​the cylinder piston, the pressure output efficiency of the cylinder and welding tongs determines the actual weldin...
