Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of welding torch, especially to an improved welding torch device. BACKGROUND

[0002] The existing welding device of compressor shell and pump body is used for quickly welding compressor semi-finished products on a conveying line, and comprises a welding machine (such as shown in the figure), a conveying line, and a compressor jacking mechanism. Figures 1 to 4 The conveying line passes through the welding machine, the conveying line is located directly below the welding machine, the compressor jacking mechanism is located directly below the conveying line, the compressor jacking mechanism is used to jacking the compressor semi-finished products on the conveying line into the welding machine, and then the welding machine is used to weld the compressor semi-finished products. The welding machine will generate slag during the welding process, and the slag will fall onto the conveying line and the compressor jacking mechanism. Therefore, the middle part of the welding machine is provided with two large slag-blocking support baffles that can be folded to be closed or opened. The conveying line and the compressor jacking mechanism are located directly below the slag-blocking support baffles, and the welding machine is located directly above the slag-blocking support baffles. When the welding machine is welding the compressor semi-finished products, the slag-blocking support baffles are closed, and most of the slag is caught by the slag-blocking support baffles. However, the existing welding device of compressor shell and pump body has the following problems:

[0003] Firstly, the support 80 of the welding torch adopts dovetail groove 83, dovetail block 82, and bolt compression cooperation. The dovetail block is slidingly arranged in the dovetail groove 83. The adjusting screw 85 is threadedly connected with the dovetail block. The adjusting screw rotates to drive the dovetail block to move, thereby adjusting the position of the welding torch. The bolt is threadedly connected with the support 80 and extends into the dovetail groove 83, and abuts against the surface of the dovetail block 82, thereby locking the position of the welding torch. Secondly, when the welding torch is welding, the slag generated during the welding process falls onto the surface of the dovetail groove 83 and the dovetail block 82, and the dovetail block is easily stuck, thereby causing the entire welding torch support 80 to be unable to adjust the position of the welding torch. Thirdly, the dovetail groove and the dovetail block are difficult to process, heavy in quality, and high in cost. Thirdly, the dovetail groove 83 and the dovetail block 82 are used for a long time, and there is a gap, which is easy to loosen and the bolt is not locked tightly. Therefore, the structure of the existing welding torch needs to be further improved. UTILITY MODEL CONTENTS

[0075] The working principle of this utility model is as follows:

[0076] When the conveyor line 3 delivers the compressor semi-finished product 9 to the area directly below the lifting seat 44, the compressor lifting mechanism 4 is activated. The lifting motor 41 drives the lifting screw 42 to rotate forward. The forward rotation of the lifting screw 42 causes the nut block 45 to rise. The nut block 45 causes the lifting slide 43 and the lifting seat 44 to rise together. The lifting seat 44 lifts the compressor semi-finished product 9 from the conveyor line 3 into the frame 1. The compressor semi-finished product 9 passes upward through the feed port 54 on the support baffle 50. Then, the lowering cylinder 721 drives the lowering plate 76 to descend. The lowering plate 76 presses down on the compressor semi-finished product 9. The first slag-blocking assembly 51 and the second slag-blocking assembly 52 are activated. The slag-blocking translation cylinder 55 drives the translation seat 57 to slide horizontally towards the upper feed port 54. The two upper slag-blocking plates 58 close together. The compressor semi-finished product 9 passes upward through the clearance opening 53 between the two upper slag-blocking plates 58. The welding machine 2 starts. The welding gun translation cylinder 63 of the multiple welding gun devices 6 drives their respective welding guns 610 towards... The compressor semi-finished product 9 moves towards the compressor housing. Multiple welding torches 610 abut against the side wall of the compressor housing. Then, the multiple welding torches 610 begin welding the compressor housing and the pump body. The pump body is located inside the compressor housing. After welding, the inner side wall of the compressor housing and the outer edge of the pump body are welded together. During the welding process, the welding slag produced will fall onto the support baffle 50 or the upper slag baffle 58, thereby preventing the welding slag from falling onto the compressor lifting mechanism 4 or being sprayed onto the welding torch device 6, which would affect the lifting and lowering of the compressor lifting mechanism 4 and the adjustment position of the welding torch device 6. After welding, the welding torch translation cylinders 63 of the multiple welding torch devices 6 drive their respective welding torches 610 away from the compressor semi-finished product 9. The lowering cylinder 721 drives the lowering plate to rise. The slag baffle translation cylinder 55 drives their respective upper slag baffles 58 to move in opposite directions. The compressor lifting mechanism 4 drives the lifting seat 44 to lower the compressor semi-finished product 9. Then, the compressor semi-finished product 9 falls onto the conveyor line 3, and then the conveyor line 3 transports the compressor semi-finished product 9 forward.
