Description
Technical field
The utility model relates to the mash welder technical field, belongs to a kind of precision resistance welder with spring.
Background technology
At present, in resistance welder, the quality of solder joint and the pressure of electrode have confidential relation, and in common resistance welder, the pressure of electrode all directly acts on generation by cylinder, for the different welding pressure of the welding requirements of different materials.The welding pressure of conventional, electric-resistance welding machine is nonadjustable basically, its welding pressure is by two factors decisions of the cylinder diameter of the pressure of source of the gas and cylinder, wants that in real work to reach the welding pressure of adjusting resistance welder all be unpractical by adjusting above two factors.
The servo-actuated of electrode also is a principal element that influences quality of welding spot.When electrifying electrodes, particularly for less precision component and be similar to the salient point soldering part, solder joint is approximate molten state owing to resistance heat becomes, require electrode must along with solder joint by conquassation and decline rapidly, otherwise can influence welding quality owing to decompression produces splash.The conventional, electric-resistance welding machine is owing to be directly to affact electrode by cylinder, and that the piston of cylinder and cylinder inner wall rub is very big, thereby the reaction speed of cylinder is slow than the reaction speed of spring.
Summary of the invention
The purpose of this utility model provides a kind of precision resistance welder of regulating the band spring of welding machine pressure.
For achieving the above object, the utility model is taked following design:
A kind of precision resistance welder with spring, it includes cylinder, the cylinder support, the top electrode seat, top electrode, lower electrode holder, bottom electrode, described cylinder is arranged on the top of cylinder support, the top electrode seat is connected the bottom that is arranged on the piston rod that stretches out under the cylinder with top electrode, on the lower electrode holder of top electrode bottom, be connected with bottom electrode, it is characterized in that: be provided with a head on the top of top electrode seat, in head, be provided with a compression spring, the upper end of this compression spring is inserted with the pressure adjustment screw bar, on this pressure adjustment screw bar, be connected with pressure and adjust nut, this pressure is adjusted nut and is pressed in the upper end of compression spring, and the upper end of described pressure adjustment screw bar is connected with the lower end of the piston rod of cylinder.
Between the madial wall of the lateral wall of head and cylinder support, interconnected right-angled intersection roller line slideway.This right-angled intersection roller line slideway is a standard component, and its effect has two: the guide effect when head descends, the unstability when having avoided spring to press down; Owing to be rolling friction, coefficient of friction is very little, thereby can guarantee the reaction speed of spring, can guarantee the servo-actuated of electrode welder.
The utility model has the advantages that:
1, owing between cylinder and head, having increased accurate compression spring, feasible more convenient to the welding that requires different welding pressure materials, adjust nut by pressure and adjust the welding pressure that the compression travel of precision spring can realize regulating welding machine.
2, owing between head and cylinder support, increased the right-angled intersection roller guide rail, thus the unstability when having avoided spring to press down; Owing to be rolling friction, coefficient of friction is very little, thereby can guarantee the reaction speed of spring, can guarantee the servo-actuated of electrode welder.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Referring to shown in Figure 1: a kind of precision resistance welder with spring, it includes cylinder 1, cylinder support 2, top electrode seat 9, top electrode 10, lower electrode holder 11, bottom electrode 12, described cylinder 1 is arranged on the top of cylinder support 2, top electrode seat 9 is connected the bottom that is arranged on the piston rod that cylinder stretches out for 1 time with top electrode 10, on the lower electrode holder 11 of top electrode 10 bottoms, be connected with bottom electrode 12, be provided with a head 6 on the top of top electrode seat 9, in head, be provided with a compression spring 5, the upper end of this compression spring 5 is inserted with pressure adjustment screw bar 3, on this pressure adjustment screw bar 3, be connected with pressure and adjust nut 4, this pressure is adjusted nut 4 and is pressed in the upper end of compression spring 5, and the upper end of described pressure adjustment screw bar 3 is connected with the lower end of the piston rod of cylinder 1.
Between the madial wall of the lateral wall of head 6 and cylinder support 2, interconnected right-angled intersection roller line slideway 7.This right-angled intersection roller line slideway is a standard component, and head 6 is moved up and down along right-angled intersection roller line slideway 7.
Between head 6 and top electrode seat 9, be provided with insulation board 8, not charged to guarantee head 6
The course of work: when the effect that is compressed air when cylinder 1 is stretched out piston rod downwards, drive the pressure adjustment screw bar 3 and the pressure thereon that are connected with piston rod and adjust the accurate compression of nut 4 promotions spring 5, promote head 6 through spring and descend, drop to top electrode 10 and part to be welded is pushed down with bottom electrode 12.After cylinder piston rod all stretched out, can adjust the welding pressure of electrode welder this moment by the impulse stroke of adjusting accurate compression spring, thereby satisfied the requirement of different welding material to welding pressure.
It is better to have increased behind the compression spring servo-actuated of electrode welder; And by cylinder action to the compression spring of precision, it is not only convenient but also accurate to adjust the welding pressure of resistance welder by the decrement of adjusting spring again.
