Description
Technical Field
The invention relates to the technical field of welding fixtures, in particular to a cleaning method for a fixture of a welding fixture.
Background
The clamp of the welding robot is used for fixing the weldment so as to ensure the size of the weldment, prevent the deformation of the weldment and improve the precision of the weldment. The clamp of the welding robot comprises a support, a positioning block, a clamping block and a sensor. During welding, lubricating oil needs to be sprayed, so that the surface of the clamp of the welding robot can be coated with oil stains and welding slag (the components of the welding slag mainly comprise metal and metal oxides) when the clamp is used for a long time, the thickness and the area of the oil stains and the welding slag can be increased along with the prolonging of the service time, and the service life of the clamp of the welding robot is influenced. When the welding robot continues to be used, the oil stains and welding slag on the surface of the clamp of the welding robot can also influence the clamping precision of the clamp of the welding robot and a weldment, and further influence the welding precision of the weldment.
At present, methods for cleaning oil stains and welding slag on a clamp of a welding robot mainly include the following two methods:
one method is to hammer the welding slag on the jig of the welding robot with a hammer to remove it, spray a degreasing agent to dissolve the oil stain on the jig of the welding robot, and then wipe the surface of the jig of the welding robot. The drawbacks of this method are: (1) the other components on a plurality of locating pieces, clamping blocks and the welding robot are distributed densely, and the clamp of the welding robot cannot be cleaned comprehensively. (2) The clamp of the welding robot is easy to deform in the process of hammering the clamp of the welding robot.
The other method is that a dry ice cleaning machine is adopted to spray dry ice particles to a clamp of the welding robot, so that the clamp of the welding robot and welding slag attached to the clamp of the welding robot contract when being cooled, because the contraction coefficients of the clamp of the welding robot and the welding slag are different, a gap is formed between the clamp of the welding robot and the welding slag after the clamp of the welding robot and the welding slag are deformed, the welding slag is loosened, and under the action of the pressure applied to the clamp of the welding robot by the dry ice particles, oil stains and the welding slag on the clamp of the welding robot are removed. However, this method also has the following drawbacks: (1) when spraying dry ice granule to welding robot's anchor clamps, the vapor in the air meets cold exothermic condensation for liquid water, and a large amount of liquid water contact along with the sensor on dry ice granule and the welding robot, easily make the impaired inefficacy of sensor. (2) The pressure of the dry ice particles sprayed by the dry ice cleaning machine is larger and reaches 8Pa, and when the dry ice cleaning machine is used for welding a robot, an electric wire is easy to damage due to impact. Meanwhile, in order to avoid injury of an operator under the action of impact force, the operator needs to wear puncture-proof protective clothing and gloves during operation, so that the operation is complex. (3) The dry ice has complex processing technology, high cost and easy melting, and has loss in the transportation process, thus causing high cleaning cost. (4) The dry ice cleaning machine has a high energy consumption.
