The purpose of this utility model is in order to overcome the weak point of above welding tractor, improves the free degree and increases work efficiency, and the spy designs a kind of new welding tractor.

The utility model is to finish by following structural design to achieve these goals.The welding tractor that the utility model provides is by railway carriage parts I, the pillar parts II that connects with railway carriage, the planker base member III and the welding gun parts IV that are fixed on the column constitute, it is characterized in that between planker base member III and welding gun parts IV, be provided with a vertical upper slide rest 10 that can move along the Z direction and idiozona handwheel screw mandrel 8 and can be on vertical upper slide rest 10 along the assembly (see figure 4) of the axially movable upper slide rest 7 of this screw mandrel, between pillar parts II and railway carriage parts I, be provided with a band handwheel screw mandrel 15 and the assembly (seeing accompanying drawing 2) of the horizontal saddle 14 that can move along this screw mandrel.In railway carriage parts I, the big end end of the large bevel gear 19 that is meshed with cone pinion 23 on being fixed on motor 24 is provided with an electromagnetic clutch 21 (seeing accompanying drawing 3).

The welding tractor that the utility model provides, owing to designed the assembling of new parts, make welding gun on the welding tractor be convenient to the adjustment of six-freedom degree, thereby easily the workpiece to various complicated shapes welds, again because of having selected electromagnetic clutch in the railway carriage for use, do not need the manually-operated clutch when welding or non-welding, bring very big convenience, improved operating efficiency to work.

Further specify the utility model below in conjunction with accompanying drawing by embodiment.

Fig. 5 is the clutch profile of prior art

Now make a long 500mm of overall dimensions, wide 330mm, the welding tractor of high 800mm, select steel for use, produce each part by machined, clutch is selected DLYO type electromagnetic clutch for use, press Fig. 1, Fig. 2, Fig. 3, Fig. 4 assembling and get final product, existing by its characteristics of use operating instruction.Welding gun 1 is installed on the axle 2, locks, unclamps locking nut 3 with locking nut 3, and welding gun 1 can rotate around axle 2, and welding gun is rotated along X-axis, realizes the Wx free degree.Support arm 4 is installed on the arm seat 5, with lock-screw 6 lockings, unclamps lock-screw 6, and support arm 4 is rotated around the axis of an arm seat 5, and welding gun is rotated around Y-axis, realizes the Wy free degree.Rotate handwheel 8, laterally upper slide rest 7 vertically moves together with the screw mandrel of an arm seat 5 along handwheel 8, and welding gun is also moved along the X axis screw mandrel, realizes the X free degree.Rotate handwheel 9, intrinsic parts are done vertical moving together on the vertical planker 10, and welding gun is moved axially along Z, realize the Z free degree.Upright post base II is installed on the horizontal saddle 14, with lock-screw 12 lockings, unclamps lock-screw 12, and column can rotate with the axis of Upright post base 13 around column self, and welding gun is rotated around the Z axle, realizes the Wz free degree.Rotate handwheel 15, laterally saddle 14 moves laterally at the screw mandrel axis of railway carriage 17 upper edge handwheels 15, and the column that is fixed on the saddle 14 is moved along X axis.At this moment, when the direction that moves when the axis and the saddle 14 of upper slide rest 7 was parallel, welding gun 1 also moved along X axis, when unclamping locking nut 12, upper slide rest 7 rotates with pillar parts II, and along rotatable 0 °～360 ° of Z axle, corner commonly used is less than 90 ° with respect to saddle 14.This moment, the axis of upper slide rest 7 was no longer parallel with the direction that saddle 14 moves.Thereby increased the free degree that XY is synthetic.Realized the six degree of freedom adjusting.

Have a look at the work (see figure 3) of clutch below again.Wheel 16 is fixedlyed connected with axletree 18, and axletree 18 is fixedlyed connected with electromagnetic clutch 21.Clutch 20 skies are enclosed within on the axletree 18, both can move axially, and can rotate around the axis again, but large bevel gear 19 can only be done axially-movable relatively.Large bevel gear 19 skies are enclosed within on the axletree 18, can only relatively rotate, can not do relative to move axially, large bevel gear 19 all the time with 23 engagements of umbellule wheel, cone pinion 23 is fixedlyed connected with motor 24.

In (non-welding) stage of adjustment, main power source is not switched on, and electromagnetic clutch 21 is not energising also, and under the effect of spring 22 elastic force, electromagnetic clutch 21 breaks away from clutch 20, no matter whether motor 24 rotates, wheel 16 can not rotate.

When electromagnetic clutch 21 energisings, the electromagnetic force in the electromagnetic clutch 21 has overcome the spring thrust of spring 22, makes electromagnetic clutch 21 and clutch 20 engagements, at this moment, if motor 24 rotates, will drive wheel 16 by the engagement of umbrella tooth and rotate, at this moment can weld.

The energising of electromagnetic clutch 21 is synchronous with main power source, when being main power source energising (welding), electromagnetic clutch 21 is also switched on, during primary power source de-energizes, electromagnetic clutch 21 also cuts off the power supply, realize the electromagnetic clutch automatic clutch like this, exempted the cumbersome operation that hand is dialled clutch when adjusting or weld, also avoided the error in the operation.
