Description

Technical Field

[0001] This utility model relates to the technical field of welding devices for compressor pump bodies and housings, and particularly to an improved welding device for compressor pump bodies and housings. Background Technology

[0002] Existing welding equipment for compressor pump bodies and housings, used for rapid welding of compressor semi-finished products on conveyor lines, includes welding machines (such as...) Figures 1 to 4 As shown), the welding machine consists of a conveyor line and a compressor lifting mechanism. The conveyor line passes through the welding machine and is located directly below it. The compressor lifting mechanism is located directly below the conveyor line and is used to lift the semi-finished compressor from the conveyor line into the welding machine. The welding machine then welds the semi-finished compressor. During the welding process, welding slag is generated and falls onto the conveyor line and the compressor lifting mechanism. Therefore, the welding machine has two large slag-blocking support plates in the middle that can be closed or opened. The conveyor line and the compressor lifting mechanism are located directly below the slag-blocking support plates, and the welding machine is located directly above them. When the welding machine welds the semi-finished compressor, the slag-blocking support plates are closed, and most of the welding slag is caught by the slag-blocking support plates. However, the existing welding device for the compressor pump body and casing has the following problems:

[0003] (1) Multiple welding gun devices are arranged in a ring at intervals on the side of the central seat 86. The seat body 84 of the welding gun device has a screw hole 85. The bolt is threaded to the screw hole 85 and passes through the screw hole 85. The end of the bolt rests against the side of the central seat 86, thereby locking the position of the welding gun device. The above locking method only relies on the bolt to be locked, and the locking is not reliable.

[0004] (2) In addition, 2.1, the welding torch bracket 80 adopts a dovetail groove 83, a dovetail block 82, and a bolt clamping fit. The dovetail block is slidably set in the dovetail groove 83. The adjusting screw 85 is threadedly engaged with the dovetail block. The rotation of the adjusting screw drives the dovetail block to move, thereby adjusting the position of the welding torch. The bolt is threadedly connected to the bracket 80 and extends into the dovetail groove 83, abutting against the surface of the dovetail block 82, thereby locking the position of the welding torch. 2.2, When welding torches are used for welding, the welding slag produced falls onto the surface of the dovetail groove 83 and the dovetail block 82, and the dovetail block is prone to jamming, thus making it impossible to adjust the position of the welding torch in the entire welding torch bracket 80. 2.3, The dovetail groove and the dovetail block are difficult to process, heavy, and costly. 2.4, The dovetail groove 83 and the dovetail block 82, when used for a long time, will have gaps and are prone to loosening.

[0005] (3) Since the lifting mechanism is located directly below the welding machine, the lifting mechanism uses a motor to drive the lifting screw to rotate. The rotation of the lifting screw drives the nut block to rise and fall, and the rise and fall of the nut block drives the lifting seat to rise and fall. Welding slag falls directly onto the lifting screw and the nut block, and the lifting screw is prone to jamming and cannot rotate, resulting in the lifting seat being unable to rise and fall.

[0006] (4) Previously, the two slag-blocking support plates had a large area and a low height. Both slag-blocking support plates needed to be opened at the same time so that the compressor semi-finished product could enter the welding device, which limited the lifting stroke of the lifting mechanism. The two slag-blocking support plates had a large area and a long gap between them, which made it easy for welding slag to fall off.

[0007] Therefore, the structure of the existing welding device for the compressor pump body and housing needs further improvement. Utility Model Content

[0036] The beneficial effects of this utility model are as follows:

[0037] 1. Compared with existing welding torch devices, the welding torch device of this utility model is securely locked on the central plate. The welding torch device of this utility model moves on the central plate through multiple rollers. The multiple rollers are positioned and supported by the central plate. Then, the locking bolt passes down through the adjustment arc groove and is threadedly connected to the screw hole of the fixed seat, thereby realizing the welding torch device being locked on the central plate.

[0038] 2.

Moreover, the screw and nut block are threadedly matched, the position is locked securely, it will not jam in the middle, the operation is stable, and it is not easy to loosen.

[0039] 3. This utility model has a small feeding port on the support baffle. Each time the compressor is lifted, only two slag baffles need to be opened. When the two slag baffles are closed, they can completely cover the feeding port, which has a good slag blocking effect. Because the feeding port area is small, welding slag is not easy to fall onto the lifting screw of the lifting mechanism below, which effectively prevents the lifting mechanism from being unable to lift.

[0040] 4. The welding torch position of this utility model is adjustable, which can be adapted to weld compressor housings of different sizes. The compressor lifting mechanism of this utility model is offset from the welding machine. Therefore, the welding slag during welding will not fall onto the lifting screw of the compressor lifting mechanism, and the lifting mechanism can lift and lower stably without jamming.

[0100] The working principle of this utility model is as follows:

[0101] 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.
