Description
Technical field
The present invention relates to a kind of welding auxiliary equipment, especially a kind of good to neutrality, repair and frustrate effective welding electrode and repair the equipment of frustrating.
Background technology
Automobile is the more fixed form of using welding of meeting in making engineering, and the welding manner in the workshop generally all is to use welding gun.Vehicle body is clamped at the two poles of the earth of welding gun, and welding is accomplished in energising.A vehicle body needs more welding position to guarantee the connectivity robustness between the car body component.
The underslung electric welding machine of general use in the body in white welding process; The power-on and power-off polar cap is clamped hundred vehicle bodies; The power-on and power-off polar cap has certain wearing and tearing through frequent welding, if untimely reconditioning, perhaps the power-on and power-off polar cap is undesirable after the reconditioning; Will influence the effect of welding, not reach the requirement of technology.If the interface between the power-on and power-off polar cap is not repaiied and is put in place; Cause the line between interface and the power-on and power-off polar cap to squint; And when body in white was welded, the plane at line between the power-on and power-off polar cap and body in white pad place was perpendicular, at this moment just caused the contact area between power-on and power-off polar cap and the body in white not reach welding requirements easily; The phenomenon of rosin joint takes place easily, brings hidden danger to vehicle body.
After long-time the use; The power-on and power-off polar cap receives the influence of electric current and high temperature; Power-on and power-off polar cap meeting galvanic corrosion, meeting wearing and tearing cause the contact area between power-on and power-off polar cap and the body in white to become big after the wearing and tearing, this just causes the electric current increase of passing more easily; Cause body in white in the welding position by through welding, produce quality problems.This also can aggravate the rate of wear of power-on and power-off polar cap.Therefore welding gun need be repaiied the power-on and power-off polar cap in the course of the work and frustrate, and makes the power-on and power-off polar cap be in rational shape all the time.
Patent Office of the People's Republic of China has announced a CN201020660Y patent on February 13rd, 2008; Name is called a kind of electrode dressing device that is used for mash welder; Comprise the rotating disk, reconditioning parts and the guider that once connect; Said reconditioning part side is provided with the reconditioning position that is used for the reconditioning electrode to the surface of guiding device; This reconditioning position is the inner groovy that extends internally along reconditioning parts end face, and said electrode passes guider and contacts with the inner groovy at friction position, and this rotating disk is fixedly connected with a end away from the reconditioning parts of guider.But this coping device can only carry out reconditioning to an end of electrode mould, can't carry out reconditioning to the power-on and power-off polar cap of body in white welding gun.
Patent Office of the People's Republic of China discloses a CN101797675A document on August 11st, 2010; Name is called on the line that is welded the fixedly automatic coping device of welding gun electrode; On the support of welding gun, be Z to rotating shaft is set, the turning arm that is center of rotation, can in XOY plane, rotates is being set with the rotating shaft in the rotating shaft; Between support and turning arm; The oscillating cylinder that turning arm is formed gusseted is set, fixedly installs coping device through the coping device backboard, on coping device, be provided with by motor-driven rotating blade in the outside of turning arm.But the welding gun of this coping device is to be fixed on the support, can not carry out reconditioning to the welding gun of activity, otherwise possibly cause the power-on and power-off polar cap after the reconditioning to misplace.
Summary of the invention
