Description

The electrode tip coping device

[technical field]

The utility model relates to a kind of coping device, especially a kind of electrode tip coping device that acts on the hitch point welding machine.

[background technology]

Widely used on the welding and assembling production lines of automotive field is suspension type fixing point welding machine, and the electrode critical piece of this welding machine is made up of electrode stem and electrode cap, and electrode stem and electrode cap adopt interference fit; In welding process, mainly be to use the electrode cap end face part owing to electrode, in welding process because pressure and the function of current cause end face after using about 300 times, will cause end wear, it is overproof to be embodied in the not gentle end face radius of end face, thereby cause welding effect not reach technological requirement, be that the solder joint area is too big and flatness is not high, will impact welding quality, finally badly influence the performance of welding device as untimely reconditioning.

At present, to the reconditioning of suspension type fixing point electrode welder, mainly contain two kinds of modes:

One is to use plain file to carry out reconditioning, and the method is simple, is easy to the workshop workman and grasps fast, but be difficult to guarantee the working size of reconditioning rear electrode, and the electrode cap cross dimensions after the reconditioning also is not easy to reach technological requirement.

The 2nd, automation source of the gas tip dresser is characterized in having a compressed air gas source and a Pneumatic quick connector, and both provide power source for coping device together, and its shortcoming is: the price height, and profile is big, and quality is heavy; To the requirement height of electrode cap, the electrode cap profile must get complete; Complicated operation, common welder is difficult to study.

Therefore, shortcomings such as, Heavy Weight big at automation source of the gas electrode dressing device price height, profile, adaptive faculty are poor, complicated operation, in order to improve the quality and the speed of welding in the automotive field, press for a kind of simple to operation, profile is little, weight is little, and low being easy to of price extensively is equipped with and effective electrode tip coping device.

[utility model content]

The purpose of this utility model be to provide a kind of simple to operation, profile is little, weight is little, low being easy to of price extensively is equipped with and effective electrode tip coping device.

The purpose of this utility model is achieved through the following technical solutions:

A kind of electrode tip coping device comprises the reconditioning parts, and described reconditioning parts are revolving body, in be provided with reconditioning face, described reconditioning face is coaxial with the reconditioning parts, and described reconditioning face is a coned face, wherein: respectively be provided with mutual coaxial reconditioning face in described reconditioning parts both ends of the surface.

Further, described coping device also comprises rotating disk and fixture, and described rotating disk cooperates by fixture with described reconditioning parts.

The revolution shape of described reconditioning parts is a cylinder.

Be provided with chip area in the described reconditioning face, described chip area is along the axis direction of coping device, and the bits that reconditioning is caused are discharged in time, thereby improves the reconditioning performance.

Described rotating disk is provided with handle, and the axial line of described handle is perpendicular to the hollow axis of rotating disk, the power when reconditioning is provided.

Described fixture is two jackscrews that symmetry is installed, and described jackscrew can easily load and unload, and makes coping device realize the electrode tip of different-diameter is carried out reconditioning.

Described rotating disk inner surface and reconditioning member outer surface are provided with the concaveconvex structure that cooperatively interacts, and described concaveconvex structure prevents rotating disk and the relative motion of reconditioning parts.

The utility model adopts simple and practical technology, its advantage is: the utility model adopts the fixture of rotating disk, removable reconditioning device and the convenient disassembly of band handle to constitute whole reconditioning device together, so it is simple in structure, be easy to processing, with low cost, using method is simple, and is simultaneously easy to carry, do not need in use electrode cap is just disassembled and can directly carry out reconditioning, better improved welding efficiency; Removable reconditioning parts have guaranteed the reconditioning of the electrode cap of different-diameter; The center of reconditioning parts excircle and its inner conical groove is coaxial to have guaranteed the quality after the reconditioning, directly the rotation reconditioning makes and need not carry out reconditioning at different parts, the fluency that chip area has guaranteed entire work process is set on coned face, the taper seat of each end face inner surface setting of reconditioning parts can realize repairing simultaneously the function of two electrode caps, has improved operating efficiency.

[specific embodiment]

Please refer to accompanying drawing 1 to accompanying drawing 3, the electrode dressing device that the utility model is used for mash welder comprises rotating disk 4, reconditioning parts 3 and the fixing jackscrew of usefulness, and described reconditioning parts 3 surfaces are provided with the reconditioning face that is used for reconditioning electrode cap 2, and this reconditioning face is the surface of similar file; Electrode stem 1 passes rotating disk 4 and reconditioning parts 3 friction positions and contacts, and finishes reparation to height point by grinding.The inner groovy of described reconditioning parts 3 is the conical tanks that extend internally along reconditioning parts 3 end faces, purpose is that electrode cap 2 reconditionings of electrode are tapered, when the pressure of spot welding constantly increases the end diameter of electrode cap 2, all the entire outer diameter than electrode is little for electrode diameter in the range of taper, so the length in the range of taper can prolong electrode increases diameter when spot welding time, thereby prolong the service life of electrode, two reconditioning faces in each end face setting of revolving body reconditioning parts, thereby realize two electrode tips of reconditioning simultaneously, thereby improved operating efficiency.

Further, described rotating disk 4 is fixedlyed connected by two symmetrical jackscrews of exterior arc surface with reconditioning parts 3, thereby relative motion does not take place in rotating disk 4 and reconditioning parts 3 during the work of assurance, in addition, described rotating disk 4 inner surfaces and reconditioning parts 3 outer surfaces are provided with the concaveconvex structure that cooperatively interacts, described concaveconvex structure also is used to prevent rotating

disk

4 and 3 relative motions of reconditioning parts, the center of this rotating disk 4 and the center of reconditioning face are coaxial, guarantee that the play phenomenon does not take place electrode cap 2 in the reconditioning process, thereby guarantee the reconditioning effect.

In order in time to get rid of the copper scale that reconditioning causes, on the inner conical groove side wall surface of described reconditioning parts 3, be provided with chip area, described chip area is the axis direction setting along coping device, makes that like this chip removal is more smooth and easy.

Select reconditioning parts for use at the electrode of different-diameter during work, thereby can improve the use face of coping device with different-diameter reconditioning face.

The course of work of the electrode dressing device in the utility model is as follows:

Electrode stem and electrode cap are fitted together, the upper and lower electrode cap of electrode is inserted the reconditioning parts simultaneously, its end contacts with the conical tank of the reconditioning parts of coping device, because the reconditioning position is the surface of similar file, rotate by unidirectional handle and to finish reconditioning, reconditioning parts and electrode cap relevant position are rubbed, thereby make electrode cap working position shape satisfy technological requirement.
