Description

Automatic spot-welding device

Technical field

The utility model belongs to field of machining, relates to the spot welding work auxiliary device.

Background technology

In modern industry is produced, adopt welding technique to make metal and nonmetal structure in a large number, in whole industrial system, be difficult to find and do not adopted welded industry, in various welding methods, more and more adopt the spot welding mode to weld at plate sheet welding, particularly in the diamond saw blade industry, the production silent saw blade all adopts two sheet metals to carry out spot welding and forms.

In this saw blade industry, because two single steel plates are welded into an integral body, carry out the welding of a plurality of points, all adopt the mode of manual rotating welding at present, labour intensity is big, and welding quality is wayward, and efficient is lower, and working environment is relatively poor.

Summary of the invention

It is a kind of easy to operate that the purpose of this utility model is to provide, high efficiency, and reduce the automatic spot-welding device of labourer's working strength greatly.

The purpose of this utility model is achieved in that a kind of automatic spot-welding device, comprises pedestal 1 and spot welding device 19, and guide plate 2 is fixed on the pedestal 1, and workbench is equipped with guide rail 4 13 times, and guide rail 4 is placed on the guide plate 2;

Limit sensors

16,17 is equipped with at the workbench two ends; Workbench motor 3 is housed on the pedestal 1, and workbench motor 3 is connected with screw mandrel 15, and screw mandrel 15 is provided with spigot nut 14, and spigot nut 14 is fixed on the workbench 13; Driving lever 12 is installed on the driven gear 6, driven gear 6 and driving gear 7 interlocks, and driving gear 7 is sleeved on the electric rotating machine 5, and driven gear 6 all is fixed on the workbench 13 with electric rotating machine 5, and cylinder 9 is connected with mandrel 10, and mandrel 10 is fixed on the workbench 13.Workpiece 11 is sleeved on the mandrel 10, the other end with link to each other with driving lever 12.

Compared with prior art, the utlity model has simple to operation, reduction operator labour intensity, improve welding quality and precision, high efficiency, and the advantage of handling safety.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of facing of the present utility model.

Fig. 2 is a plan structure schematic diagram of the present utility model.

The specific embodiment

Find out that from attached Fig. 1 and 2 automatic spot-welding device is by pedestal 1, guide plate 2, workbench motor 3, guide rail 4, electric rotating machine 5, driven gear 6, driving gear 7, workpiece sensor 8, cylinder 9, mandrel 10, workpiece 11, driving lever 12, workbench 13, spigot nut 14, screw mandrel 15,

limit sensors

16,17, PLC controller 18 and mash welder 19 are formed.

Workpiece 11 is sleeved on the mandrel 10, and cylinder 9 is connected with mandrel 10 with workpiece 11, and workpiece 10 can rotate and move up and down around mandrel 10, and mandrel 10 is fixed on the workbench 13; Workpiece 11 links to each other with driving lever 12 simultaneously, driving lever 12 drives workpiece 11 rotations, driving lever 12 is installed on the driven gear 6, driven gear 6 and driving gear 7 interlocks, driving gear 7 is sleeved on the electric rotating machine 5, driven gear 6 all is fixed on the workbench 13 with electric rotating machine 5, thereby has workpiece 11 rotations by electric rotating machine 5 startups; Workbench is equipped with guide rail 4 13 times, guide rail 4 is placed on the guide plate 2, can after going forward, guide plate 2 move back and forth, guide plate 2 is fixed on the pedestal 1, and pedestal 1 is equipped with workbench motor 3, and workbench motor 3 is by screw mandrel 15 and spigot nut 14 suits, spigot nut 14 is fixed on the workbench 13, on the pedestal 1 fixing ground again, PLC controller 18 is installed in by the automatic spot-welding device, and whole device is adorned mash welder 19 fronts again.

The course of work of the utility model automatic spot-welding device is as follows:

At first start-up point welding machine 19 and PLC controller 18 power supplys, workpiece 11 is sleeved on the mandrel 10, in location parameter input PLC controller 19 with required spot welding on the workpiece 11, begin to weld, cylinder 8 rises, workbench motor 3 starts, be delivered on the spigot nut 14 by screw mandrel 15, drive the radial position that workbench 13 advances or retreats into workpiece 11 required spot welding, in this process, if workbench 13 is run into limit sensors 16 or, workbench 13 stop motions at 17 o'clock; Electric rotating machine 5 work then, driving gear 7 drives driven gear 6 rotations, driven gear 6 drives the circumferential position that workpiece 11 rotates to required spot welding by driving lever 12, cylinder 9 falls, 19 pairs of workpiece 11 of mash welder weld, if when workpiece sensor 8 did not detect workpiece 11, mash welder 19 quit work; After welding was finished, cylinder 9 rose, and workbench 13 drives the position that workpiece 10 moves to next spot welding, and mash welder 19 welds, and repetitive process is finished until whole work-piece 13 welding, returns to initial position, and cylinder 9 falls, and finishes whole welding process.
