Description
Technical field
The present invention relates to a kind of weld jig of parts, more particularly to a kind of irregular parts weld jig and its weldering
Connect method.
Background technology
The welding of irregular parts is prevalent in parts industry, its welding method and electroplating equipment wielding machine, fixture
Etc. varying, performance and function differ；The reliable fixture of method simple and stable, can effectively lift effect and the weld part of welding machine
The quality of part, improving operating environment, and realize electroplating equipment wielding machine includes the essential safety of fixture.
The control stick of motor vehicle operator control system, is the extremely important part of steerable system of automobile, by irregular parts
The parts and components such as stock and bearing pin are welded.And the welding quality of control stick is crucial, reliability that it is directed not only to shift gears,
Stability, and the safety of running car is also related to, welding position offsets or comes off, and will all have potential danger, current row
The welding of control stick is used mostly robot welding or projection welding in the industry, and the former belongs to consumable electrode weldering, and equipment investment is big, takes up an area face
Product is big, and welding heat affected region is big, and deformation is big, and welding quality is difficult to ensure that, efficiency is low, high cost, therefore this welding method is gradually
Gradually in superseded；The latter belongs to electric resistance welding, and the method heat is concentrated, and welding heat affected region is little, efficiency high.
No matter which kind of welding, the clamping method that will have and excellent fixture are ensureing the optimization of welding function and carry
Rise.In parts industry, robot welding tends to a superseded major reason, is just because that clamping method is subject to machine
The restriction of people's welding robot system, weld jig exploitation are difficult, and fixture is expensive, it is impossible to adapt to many specifications of multi items technique and
Benefit requires and meets with and gradually eliminate.
At present in parts industry, the parts and components such as irregular parts stock and bearing pin are carried out using projection welding
During welding, its clamping method and fixture, great majority be using by part to be welded (as bearing pin) by Top electrode clamping position, then with not
Regular parts (as stock) is welded, hereinafter referred to as upper welding；Or using part (as bearing pin) to be welded with irregular
Parts (as stock) are arranged on the horizontal plane vertical with the electrode welder direction of motion and are welded, hereinafter referred to as horizontal position
Welding.The wherein upper defect for being welded with two aspects：One is cannot to realize Top electrode to the accurate and firm of part to be welded
Clamping, and because always there is the clamping gap of 0.2mm between electrode and part to be welded, when causing to weld, conductive contact area is little,
Conductive capability is deteriorated, and contact resistance becomes big, and welding heat is raised, and welding efficiency and security reduce.Two is electrode and to be welded zero
The gap that clamps for always having 0.2mm between part causes the error of clamping itself, needs debugging calibration in the welding job preparatory stage；?
In the course of work, with the abrasion of electrode and the accumulation of error, need adjustment calibration again is shut down, error is eliminated, causes efficiency
Lowly, defective products increases, and affects job schedule.Horizontal position welding manner has welding scaling loss displacement (molten bath shortens) cannot be timely
, there is rosin joint in the defect of elimination, dislocation, and gravity deformation etc. causes welding assembly positional precision bad, and yield rate lowers, and
As rosin joint causes the firmness of weldment to decline, the safe handling of terminal use is affected.
