Abstract
The invention provides a novel spot-welding electrode trimming head to replace a traditional trimming blade. The novel electrode trimming head is manufactured by sintering abrasive materials on a metal machine body. In the using process, an upper electrode and a lower electrode directly stretch into the trimming head, and the electrodes can be trimmed into required formed electrodes through rotation of the trimming head. The trimming head is suitable for trimming all resistance spot-welding type equipment electrodes with the technological requirement ranges that the diameter is phi 16, the spherical radian requirement of the electrodes is SR20, and the central welding spot diameter is phi 6-8. The novel spot-welding electrode trimming head is easy to use and convenient and safe to operate, the application cost is greatly reduced compared with the traditional blade, and the novel spot-welding electrode trimming head is suitable for all automobile industries and sheet metal lap welding machining.
Description
Technical field
The invention belongs to dressing technique field, more particularly, to a kind of method for trimming of scaling loss spot-wedling electrode.
Background technology
Due to the continuous improvement that automobile corrosion resistance is required, galvanized sheet has become indispensable material in automobile making
One of material.The corrosion resistance of galvanized steel plain sheet is strong, has substituted traditional cold-rolled steel sheet in a large number as body material, to improve car
Resistance to corrosion and whole service life.The welding method mainly being adopted in welding using the vehicle body of galvanized steel plain sheet is resistance
Spot welding.In resistance welding technology, due to High Temperature High Pressure, one layer of Cu5Zn8（Copper zinc）Alloy-layer will be deposited on electrode.Many
After secondary accumulation, electrode will be dumped lamination and cover, and the final electrode that damages is in some instances it may even be possible to cause lead rupture.Some alloy-layers can be from
Peel off on electrode, glue on a metal plate, thus result in bodywork surface defect.In addition alloy is bonded on electrode surface, leads to pass through
Electric current reduces so that welding condition is deteriorated, or even forms cold welding.Electrode tip therefore must be changed or take some measures clear
Clean electrode surface, keeps good welding condition.The measure of cleaning electrode surface mainly relies on experienced workman's handss at this stage
Work reconditioning, not only grinding efficiency is low, quality of workers is required higher and also be difficult to reach standardization radius tip electrode requirement and in
Heart point straight line requires.
Content of the invention
It is an object of the invention to provide a kind of scaling loss spot-wedling electrode method for trimming is it is intended to solve existing scaling loss spot welding electricity
During the reconditioning of pole, efficiency is low, high cost, reconditioning scope unreasonable it is impossible to the defect such as powered reconditioning on a production line, effectively protect
The card end face of welding electrode and the uniform standardization of spot size and improve grinding efficiency.
The present invention is achieved in that a kind of new spot-wedling electrode reconditioning bistrique work process comprises the following steps：
（1）Mash welder is adjusted to debugging mode, and the clamping force of mash welder soldering turret is adjusted in suitable scope；
（2）The soldering turret stroke of mash welder is opened, spot-wedling electrode reconditioning bistrique is placed between upper and lower two electrodes, presses out
Close, make upper and lower two electrode clamping reconditioning bistrique matrixes；
（3）Start arrangement for grinding, bistrique starts to rotate, and carries out reconditioning to the spot-wedling electrode of scaling loss；
（4）Its electrode sphere and center spot size are to be ensured by electrode dressing bistrique, reach criterion and quantity requirement；
（5）Reconditioning matrix material selects suitable wear particle size, and has a number of arc chip area, thus ensureing to repair
During mill, abrasive dust does not block bistrique；
（6）The outer grind box equipped with insulation of reconditioning bistrique matrix, it is possible to achieve powered reconditioning on production line；
The present invention replaces traditional blade to carry out reconditioning to the spot-wedling electrode of scaling loss using bistrique, and wherein grind box adopts insulant
It is designed, thus the insulation during ensure that reconditioning is thus realize powered online reconditioning.The service life of reconditioning bistrique will
More much higher than conventional blades, greatly reduce reconditioning cost.And avoid conventional blades reconditioning scope not during repairing mill
Rational defect, improves grinding efficiency.Due to employing modularized design, this arrangement for grinding can directly substitute traditional repairing
Sharpening sheet is arranged on existing pneumatic coping device becomes a kind of new spot-wedling electrode Regrinding System, thus being suitable for all kinds of automobiles
Manufacturing enterprise be welded workshop use.
Brief description
The plane view of Fig. 1 novel spot welding electrode dressing bistrique and top view.
Specific embodiment
A kind of work process of the new online reconditioning bistrique developed for scaling loss spot-wedling electrode has following step：
(4) reconditioning finishes.
(3) actuating motor 7, drive belt 4 by power transmission shaft, and belt 4 drives and drives box 3 to start to rotate, structure as shown,
Grind box 2 is fixed on driving box 3 to rotate together among driving box, and bistrique matrix 1 coheres in grind box 2 with grind box 2
Rotation, starts to carry out reconditioning to scaling loss spot-wedling electrode；
(2) as shown in figure 1, the soldering turret that will be equipped with scaling loss spot-wedling electrode is opened, by the two spot-wedling electrode be aligned reconditioning up and down of scaling loss
The reconditioning area of bistrique, presses mash welder switch, clamps reconditioning bistrique matrix 1；
(1) (size of spot-wedling electrode is a diameter of Φ 16, and electrode sphere radian is SR20, and center is welded will to be provided with scaling loss electrode
Spot diameter is Φ 6) mash welder be adjusted to debugging mode, and the clamping force of mash welder is reduced in certain scope；
Compared to the shortcoming and defect of prior art, the invention has the advantages that：
（1）The present invention, by replacing traditional hand grinding to substantially increase the efficiency of reconditioning using reconditioning bistrique, greatly shortens
Because the production line time caused by reconditioning electrode.（2）The present invention substantially increases the precision of reconditioning using reconditioning bistrique, has
Effect ensures end face and the uniform standardization of spot size of welding electrode, quantifies to require, thus improve the quality of solder joint, extends
The service life of electrode, reconditioning bistrique matrix outer equipped with insulation sleeve, it is possible to achieve powered reconditioning on production line；（3）The present invention
Compared with traditional reconditioning blade, greatly reduce use cost, and extend the use time of grinding tool itself；（4）
The present invention can replace completely with existing reconditioning blade, be directly installed on existing pneumatic polishing device and become a kind of new
Spot-wedling electrode Regrinding System.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
