Abstract
The utility model relates to a piston rod assembly spot-welding tool of a vibration absorber, which is provided with a bottom plate. A fixed V-type block, a movable V-type block, a positioning stop block and a rotating mechanism are arranged on the bottom plate. The fixed V-type block is used for placing a piston rod, the movable V-type block can be moved, and the rotating mechanism is used for driving the piston rod to rotate. The tool can reliably ensure the consistency of the spot-welding standards, improve the welding precision and ensure the product quality; moreover, the spot-welding tool has the advantage of simple structure and is convenient to operate and can reduce work intensity and improve work efficiency.
Description
Technical field
The utility model belongs to the welding tooling technical field, is a kind of damper piston-rod assembly spot welding frock.
Background technology
In technique known, a kind of automobile vibration damper piston rod assembly is eased up and is formed towards three kinds of parts of spring by piston rod, buffering back-up ring, in the assembling welding of piston-rod assembly, usually the method that adopts is: earlier buffer spring is placed on the V-block, to be enclosed within buffering back-up ring above the piston rod again and be placed on mash welder up and down between two electrodes, bottom electrode is motionless, presses down energising by top electrode, will cushion back-up ring and be welded on the piston rod.In welding process, because buffering back-up ring circumference needs spot welding 4 points, a spot welding can be welded 2 points, and other 2 needs are finished by manual rotation, so the location of piston-rod assembly is to support and two-handed hand-held by a V-block.This welding manner is easy to cause the swing of piston rod non-directional, the center that upper/lower electrode departs from piston rod when causing welding, 4 that make the weldering of buffering back-up ring upper point on same disc, be difficult to reach the specification requirement of pulling-out force and fusion penetration, make product easily produce great hidden danger of quality, also increased labour intensity and product cost simultaneously.
The utility model content
The purpose of this utility model provides a kind of shock absorber piston rod spot welding frock that can guarantee welding quality, improve welding efficiency.
Realize that the technical scheme that the purpose of this utility model is taked is: this frock has a base plate, base plate is provided with fixedly V-block, the moveable V-block that is used to put piston rod, and a position block and a rotating mechanism that is used to drive the piston rod rotation.
Governor motion is equipped with in the bottom of described movable V-block, this mechanism is made up of supporting plate, portable plate, threaded post and screw shaft, wherein, supporting plate is packed on the base plate, portable plate is positioned at supporting plate top, and fixedly connected with movable V-block, supporting plate is provided with the threaded post that is used for the piston rod lift adjustment, be used for the screw shaft of regulating piston bar radial level position and be used for the adjusting bolt of the axial horizontal level of regulating piston bar.
Described rotating mechanism has a micro-step motor and a travel switch that is used for the control piston bar anglec of rotation, and this motor is connected with piston rod by shaft joint.
Shock absorber piston rod spot welding frock according to such scheme is made has unified location benchmark, has guaranteed the uniformity of whole frock benchmark, improves welding precision, guarantees product quality, and this frock can adapt to the piston rod welding of different size, highly versatile.The movable V-block that increases can make the piston rod free state be placed on the frock, adjustment can move up and down, make piston rod be in level all the time, and the line that makes four two symmetric points on the buffering back-up ring need not manpower and control all the time by the center of piston rod.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, each label is respectively position block 1, base plate 2, V-block 3, supporting plate 4, V-block 5, threaded post 6, portable plate 7, top electrode 8, bottom electrode 9, buffering back-up ring 10, piston rod 11, rotating mechanism 12, buffer spring 13, screw shaft 14, regulates bolt 15 among the figure.
Damper piston-rod assembly spot welding frock of the present utility model has a base plate 2 that is used to support whole frock, and base plate 2 can be fixed on the workbench of mash welder.Base plate 2 is provided with can put piston rod 11 and the fixedly V-block 3 that is located, can regulate mobile movable V-block 5, and position block 1 and one can drive the rotating mechanism 12 that piston rod radially rotates.Governor motion is equipped with in bottom at movable V-block 5, this mechanism is by supporting plate 4, portable plate 7, threaded post 6, screw shaft 14 and adjusting bolt 15 are formed, wherein, the bottom surface of supporting plate 4 contacts with base plate 2, and be fixed on the base plate 2, portable plate 7 and movable V-block 5 are positioned on the supporting plate 4, and threaded post 6 is housed at the two horizontal diagonal two-end part, the upper lateral part of supporting plate 4 is equipped with screw shaft 14, its two ends are equipped with and are regulated bolt 15, by threaded post 6, screw shaft 14 and regulate bolt 15, can drive portable plate 7 respectively realization activity V-block 5 upper-lower positions adjusting and with the adjusting of piston rod 11 horizontal levels.
Operation principle: in welding process, earlier buffer spring 13 is seated on V-block 3 and the movable V-block 5, be enclosed within buffering back-up rings 10 above the piston rod 11 and be placed on mash welder up and down between two electrodes 8,9, bottom electrode 9 is motionless, and top electrode 8 presses down energising and will cushion back-up ring 10 and be welded on and finish on the piston rod 11.This frock is in the axial front portion of piston rod 11 position block 1 to be set, in order to the axial location of piston rod 11, on justifying in a cross section all the time when making the rotation of piston rod 11 circumference; On the fixing right side of V-block 3 a movable V-block 5 is set again, this movable V-block 5 can move up and down along threaded post 6 with portable plate 7; Supporting plate 4 is provided with screw shaft 14, turn screw shaft 14, movable V-block 5 can with supporting plate 4 move left and right together, piston rod can be placed steadily all the time, be in level; Top electrode 8 and bottom electrode 9 all are fixed on the mash welder workbench, buffering block 10 can be welded on the piston rod 11 in the time of in working order, and piston rod 11 can move axially with circumference in two V-blocks 3,5 and rotate; Rotating mechanism 12 is driven by a micro-step motor, and this motor is connected with piston rod 11 by driving member and revolution holder (not shown).Which is provided with the travel switch that is used for the control piston bar anglec of rotation, the anglec of rotation of piston rod 11 can be controlled by travel switch, so that 90 ° of rotations of piston rod circumference adapt to the requirement of electric welding position.
