Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of compressor shell and pump body's welding device, especially to a kind of improved welding device of compressor shell and pump body. BACKGROUND

[0002] The existing compressor shell and pump body welding device is used for quickly welding compressor semi-finished products on the conveying line, which includes 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, and 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 lift 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. During the welding process of the welding machine, slag is generated, which 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 close or open. 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.

[0003] (1) Since the jacking mechanism is located directly below the welding machine, the jacking mechanism is driven by a motor to rotate the lifting screw rod, which drives the nut block to lift, and the nut block drives the jacking seat to lift. Even with the slag-blocking mechanism, slag will fall onto the lifting screw rod and the nut block, which will cause the lifting screw rod to be stuck and unable to rotate, resulting in the jacking seat being unable to lift. Therefore, the structure of the existing jacking mechanism needs to be further improved. SUMMARY

[0004] The utility model aims at providing an improved welding device for compressor shell and pump body that is stable in use.

[0005] The utility model is realized as follows:

[0006] An improved welding device for compressor shell and pump body, comprising a rack;

[0007] A welding machine is hung on the rack and used to weld compressor semi-finished products.

[0008] A slag-blocking mechanism is provided on the rack and located below the welding machine to catch slag.

[0009] A conveying line is located below the rack and used to convey compressor semi-finished products to the compressor jacking mechanism.

[0010] A compressor jacking mechanism is provided at the bottom of the rack and used to lift the compressor semi-finished products on the conveying line to the welding machine.

[0011] The compressor jacking mechanism comprises a supporting base, a lifting motor, a lifting slide base, a lifting screw rod, a nut block and a jacking base, the lifting screw rod is vertically arranged on the supporting base, the lifting motor is arranged on the supporting base and drives the lifting screw rod to rotate, the lifting screw rod is in threaded connection with the nut block, the nut block is fixedly connected with the lifting slide base, the lifting slide base is arranged on the supporting base and can slide up and down, and the jacking base is arranged on the lifting slide base, and the lifting screw rod is arranged in dislocation with the feeding opening.

[0012] The compressor jacking mechanism has the advantages that the lifting screw rod of the compressor jacking mechanism is arranged in dislocation with the welding machine, therefore, welding slag generated during welding of the welding machine cannot fall on the lifting screw rod of the compressor jacking mechanism, and the compressor jacking mechanism is stable during lifting and cannot be stuck.

[0013] The compressor jacking mechanism has the advantages that the lifting screw rod of the compressor jacking mechanism is arranged in dislocation with the welding machine, therefore, welding slag generated during welding of the welding machine cannot fall on the lifting screw rod of the compressor jacking mechanism, and the compressor jacking mechanism is stable during lifting and cannot be stuck.
