Description

Energy storage double end mash welder

Technical field

The utility model relates to a kind of welder, relates in particular to a kind of energy storage double end mash welder, and this welding machine is applicable to two situations that nut welds of two thick sheet metals folder.

Background technology

Usually automotive seats front side board assembly structure as shown in Figure 1 because gross thickness H value is big, if two nuts weld simultaneously, present domestic technique condition is immature to be difficult to guarantee ordinary production.Existing solder technology is that two nuts are welded respectively, because welding process two nuts will locate respectively, so that positional precision is difficult to guarantee, and production efficiency is low.

Summary of the invention

For overcoming above-mentioned deficiency, the utility model provides a kind of rational in infrastructure, energy storage double end mash welder that welding efficiency is high, and caloric value is few, once can weld two nuts, need not two nuts are welded respectively.

Structure of the present utility model comprises fuselage 1, weld cylinder and top electrode assembly 2, and lower rotary table assembly 3, weld cylinder and top electrode assembly 2 are installed in fuselage 1 top, and lower rotary table assembly 3 is installed on the workbench of fuselage 1.Weld cylinder and top electrode assembly 2 comprise: be fixed on gas-liquid power-increasing cylinder 21 and guideway 22 on the fuselage, be connected along the movable part 23 of guideway 22 activities with gas-liquid power-increasing cylinder 21, be fixed on the copper bar 24 on the movable part 23, the electrode tip holder 25 that is connected with copper bar 24, be fixed on the cartridge 26 that powers on of top electrode seat 25, consult shown in Figure 3.Wherein copper bar 24 links to each other with the energy storage transformer by the soft copper band.

Lower rotary table assembly 3 of the present utility model comprises: be fixed on the rotating disk 34 that fuselage can freely rotate, be fixed on the beneath axle sleeve 32 of rotating disk, be installed in the spring 31 on the axle sleeve 32, be inserted in the guide post 30 of 31 li on spring, be contained in axle sleeve upper spring 35 and towing plate 33, be fixed on the middle bottom electrode head 39 of towing plate, be contained in the workpiece location-plate installing plate 38 on the bottom electrode head 39, be contained in the workpiece location-plate 37 on the workpiece location-plate installing plate.Wherein under the bottom electrode head 39 the hard copper row who links to each other with the energy storage transformer.

The operation principle of the utility model device is as follows, workpiece is placed on the workpiece location-plate 37, gas-liquid power-increasing cylinder 21 work, it is descending along guideway 22 to drive movable part 23, and cartridge 26 is run into workpiece when powering on, thereby compression spring 31 and spring 35 make the bottom electrode head descending along guide post 30, until meeting the hard copper row who links to each other with the energy storage transformer, the welding work pieces of transformer discharge at this moment is behind the weldering finished piece(s), movable part 23 is up, and spring 31 and spring 35 resiliences make bottom electrode head 39 leave hard copper row.

Advantage of the present utility model

The utility model is rational in infrastructure, welding efficiency is high, caloric value is few, once can weld two nuts, accurate positioning, and the precision height can reduce labour intensity effectively, saves time.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

We adopt energy storage double end mash welder as shown in Figure 2, and it comprises fuselage 1, weld cylinder and top electrode assembly 2, lower rotary table assembly 3.Weld cylinder and top electrode assembly 2 comprise: be fixed on gas-liquid power-increasing cylinder 21 and guideway 22 on the fuselage, be connected along the movable part 23 of guideway 22 activities with gas-liquid power-increasing cylinder 21, be fixed on the copper bar 24 on the movable part 23, the electrode tip holder 25 that is connected with copper bar 24, be fixed on the cartridge 26 that powers on of top electrode seat 25, consult shown in Figure 3.Wherein copper bar 24 links to each other with the energy storage transformer by the soft copper band.

Lower rotary table assembly 3 of the present utility model comprises: be fixed on the rotating disk 34 that fuselage can freely rotate, be fixed on the beneath axle sleeve 32 of rotating disk, be installed in the spring 31 on the axle sleeve 32, be inserted in the guide post 30 of 31 li on spring, be contained in axle sleeve upper spring 35 and towing plate 33, be fixed on the middle bottom electrode head 39 of towing plate, be contained in the workpiece location-plate installing plate 38 on the bottom electrode head 39, be contained in the workpiece location-plate 37 on the workpiece location-plate installing plate, consult shown in Figure 4.Wherein under the bottom electrode head 39 the hard copper row who links to each other with the energy storage transformer.

The workpiece that we will weld is placed on the workpiece location-plate 37, start the machine, gas-liquid power-increasing cylinder 21 is started working, it is descending along guideway 22 to drive movable part 23, the cartridge 26 that powers on is run into the workpiece that will weld, thereby compression spring 31 and spring 35 make the bottom electrode head descending along guide post 30, until meeting the hard copper row who links to each other with the energy storage transformer, at this moment energy storage transformer discharge, the cartridge 26 that powers on begins welding work pieces simultaneously with bottom electrode head 39.Behind the weldering finished piece(s), movable part 23 is up, and spring 31 and spring 35 resiliences make bottom electrode head 39 leave hard copper row.
