Abstract
The utility model discloses a projection welding tool of a vibration damper piston rod and a fixed earring, comprising a projection welding upper die, a projection welding clamping half, and a projection welding lower die. The projection welding clamping half clamps a rod body of the piston rod, and is embedded with a lower die half sleeve made of insulating materials. During the clamping, the lower die half sleeve clings to the outer surface of the piston rod. The projection welding tool of a vibration damper piston rod and a fixed earring is advantageous in that sparking frequency during the projection welding process of the piston rod and the fixed earring can be reduced, and quality of the vibration damper can be improved; claim caused by the oil leakage of a vibration damper assembly is decreased; the replacing and maintenance frequency of the tool can be reduced from one replacing in ten days in average to one replacing in three months in average; the service lifetime of the tool can be prolonged by nine times, production efficiency can be improved, and producing cost of the vibration damper can be decreased; copper materials are saved, and producing and processing cost of the tool can be saved.
Description
Technical field
The utility model relates to vehicle shock absorber processing tool equipment, and specifically, the utility model relates to a kind of shock absorber piston rod and fixed lug projection welding frock.
Background technology
At present, when shock absorber piston rod and fixed lug weld, the piston rod surface sparking often taking place, cause surface damage on piston rod, also possibly flow into down preface for spark phenomenon is not obvious on the projection welding frock.Piston rod is the shock absorber key components and parts, and surface damage place and shock absorber packing gland can produce friction, causes oil seal lip to damage and causes the defective shock absorber leakage of oil.
The basic reason that the sparking of shock absorber piston rod surface produces is:
1, when piston rod surface and the slight distortion of frock binding face generation, contact-making surface i.e. a bit contact, and the back that switches on produces sparking, and welding slag and burn can appear in the sparking position;
2, present frock naked is protected, and welding produces a large amount of heats, produces slight deformation when receiving workpiece pressure, causes sparking.
The spark phenomenon that the slight distortion that takes place for fear of the frock binding face causes, changing a secondary clamping tool average per ten working days is that piston rod clamps Hough with solid earrings projection welding, even do not calculate processing charges, only copper material also is a waste that can not be ignored.
In sum; Prior oscillating damper piston rod and fixed lug projection welding frock are relatively backward; Sparking problem in piston rod and the fixed lug projection welding process is more outstanding, and the further raising that this has restricted the vehicle shock absorber quality has to a certain extent increased manufacturing cost.
The utility model content
The utility model technical problem to be solved provides and a kind ofly in projection welding process, reduces the projection welding frock that spark phenomenon produces at piston rod and fixed lug.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of shock absorber piston rod and fixed lug projection welding frock; Comprise that projection welding patrix, projection welding clamp Hough and projection welding counterdie, projection welding clamps the shaft of Hough clamping piston bar, clamps on the Hough in said projection welding and studs with the counterdie Hough cover of processing for insulating materials; When clamping, counterdie Hough cover is fitted with the outer surface of said piston rod.
Said counterdie Hough is set in the end that said projection welding clamps Hough; Projection welding clamps the inner surface of the position, the other end of Hough and also fits with the outer surface of said piston rod, has the space between the inner surface between the both ends of projection welding clamping Hough and the outer surface of piston rod.
The material of said counterdie Hough cover is duroplasts, pottery or bakelite.
The utility model adopts technique scheme, and 1, reduced the sparking frequency of occurrences in piston rod and the fixed lug projection welding process, improved the quality of shock absorber; 2, reduced the claim that vibration damper complement causes because of leakage of oil; 3, reduced frock and changed and frequency of maintenance, changed a frock in average ten days in the past, changed a frock in average three months now, prolonged 9 times the service life of frock, improved production efficiency, also reduced the shock absorber manufacturing cost simultaneously; 4, practice thrift copper material and frock and made processing charges.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the user mode of the utility model;
Mark among the above-mentioned figure is: 1, projection welding patrix; 2, projection welding clamps Hough; 3, projection welding counterdie; 4, screw; 5, counterdie Hough cover; 6, piston rod; 7, space.
The specific embodiment
As shown in Figure 1; A kind of shock absorber piston rod of the utility model and fixed lug projection welding frock; Comprise that projection welding patrix 1, projection welding clamp Hough 2 and projection welding counterdie 3; Projection welding patrix 1 and projection welding counterdie 3 are identical with prior art, and it is the good material that hardness is arranged again of electric conductivity that projection welding clamps Hough 2, as: chromium zirconium copper, hardness are greater than 75HRB.The tight Hough 2 of screw 4 fixed convex weld clips is on projection welding counterdie 3.Projection welding clamps the shaft of Hough 2 clamping piston bars 6; This projection welding frock clamps in projection welding and studs with the counterdie Hough cover of processing for insulating materials 5 on the Hough 2; During projection welding; Piston rod 6 is clamped Hough 2 by projection welding and embraces piston rod 6 and clamping simultaneously with counterdie Hough cover 5, and counterdie Hough cover 5 is fitted with the outer surface of piston rod 6.With respect to the projection welding frock of original technology, this projection welding frock has reduced the sparking frequency of occurrences in piston rod 6 and the fixed lug projection welding process, the functional reliability and the service life of having guaranteed vibration damper complement.
As shown in Figure 2; Counterdie Hough cover 5 is located at the end that projection welding clamps Hough 2; Projection welding clamps the inner surface of the position, the other end of Hough 2 and also fits with the outer surface of piston rod 6, has space 7 between the inner surface between the both ends of projection welding clamping Hough 2 and the outer surface of piston rod 6.Like this, projection welding clamping Hough 2 has only top to contact with piston rod 6 and conducts electricity, and there is space 7 centre, and the bottom contacts with piston rod 6 but be non-conductive.
The material of the counterdie Hough cover 5 of concrete insulation is duroplasts, pottery or bakelite etc.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
