The present invention has obtained following beneficial effect with respect to prior art: welding gun is fixed on the gun stock, outside the cavity that location-plate is fixed, body stretches in the cavity, during the waist shape elongated slot scroll forward and backward of bearing on body, the gun platform band gun rack, gun stock and welding gun and is also moved forward and backward in cavity, and the prolongation of arm when being equivalent to weld can be finished the welding in inside, the dark chamber of workpiece smoothly, hand can be held the small of the stock on the gun stock in the cavity outside during welding, the visibility when having increased welding in the chamber; Bearing rolls along waist shape elongated slot and has guaranteed that it is that a straight line also is parallel to weld seam all the time that welding gun seesaws constant; And gun platform can make welding gun realize fine motion up and down around the macro-axis rotation, gun rack rotates around little axle and can make welding gun realize the fine motion of horizontal direction, the straight line that seesaws during welding with need not control with weld seam parallel, only need the control welding gun to get final product with the synchronous fine motion of horizontal both direction up and down, improve the quality and the efficient of welding, reduced labour intensity.
As improvement of the present invention, also be provided with the kidney slot that is parallel to the location-plate length direction on the location-plate, bolt passes kidney slot described body is connected with location-plate.Kidney slot is set on the location-plate, can moves laterally to the position that needs for body and fix, to satisfy the welding position needs of determining on the housing width direction.
As a further improvement on the present invention, be provided with many group fixing holes along the baseplane length direction of described body, the horizontal line of every group of fixing hole all is parallel to the axis of location-plate kidney slot.Select the fixing hole of different groups for use, can regulate the degree of depth that body stretches into cavity.
As another improvement of the present invention, body two outsides are respectively equipped with the guard shield with waist shape elongated slot and bearing sealing.Guard shield can prevent that welding slag is splashed in the waist shape elongated slot of body.
As another improvement of the present invention, extractor fan also is installed on the body, the inlet scoop of extractor fan is positioned at the front end of body, and exhaust outlet is positioned at outside the end of body.During welding, open extractor fan, the smog in the cavity in time can be discharged, guarantee that sight line is good.
Description of drawings
Fig. 1 takes away front view behind the welding gun for the present invention;
Fig. 2 takes away left view behind the guard shield for Fig. 1.
Among the figure: 1 body, 2 bearings, 3 macro-axis, 4 gun platforms, 5a left side gun rack, the right gun rack of 5b, 6 little axles, 7 bearing baffles, 8 guard shields, 9 gun stocks, 10 location-plates, 11 workpiece lumen, 12 welding guns, 13 waist shape elongated slots, 14 inlet scoops.
The specific embodiment
As shown in Figures 1 and 2, deep cavity welding tool of the present invention, comprise body 1, location-plate 10, gun platform 4, gun rack and gun stock 9, the equal height of body 1 is provided with two waist shape elongated slots 13, the body bottom is connected on the location-plate 10, and the length of two waist shape elongated slots 13 is to the length direction that all is parallel to body 1, and the baseplane length direction of body 1 is provided with many group fixing holes, the length that the line of every group of fixing hole all is parallel to the kidney slot on the location-plate 10 to, fixing hole can adopt screw.
Also be provided with the kidney slot that is parallel to location-plate 10 length directions on the location-plate 10, bolt passes the fixing hole that kidney slot is screwed into body 1 bottom, and body 1 and location-plate 10 are coupled together.
