Description

Technical Field

[0001] The utility model relates to the technical field of rotor compressor production, in particular to a splash-proof welding machine for sealing and welding the shell of a rotor compressor. Background Technique

[0002] Rotor compressors are widely used in refrigeration equipment such as air conditioners. Manufacturers produce them in batches through an automatic production line. The last step in the production process requires sealing and welding the shell of the rotor compressor. Currently, some manufacturers use automatic welding machines for welding. As Figure 3 shown, the welding machine is arranged on one side of the production line 8. The rotor compressor 9 on the production line 8 is continuously fed into the welding machine by a manipulator 10, and the welding machine automatically performs welding. The following technical problems exist in actual production: When the welding machine welds, some welding slag will splash outwards. If the welding slag flies onto the rotor compressor on the production line and enters the compressor interior through the intake pipe, it will cause the compressor to malfunction, thus reducing the yield rate. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art, and to provide a splash-proof welding machine for sealing and welding the shell of a rotor compressor.

[0004] The specific scheme of the utility model is: a splash-proof welding machine for sealing and welding the shell of a rotor compressor, including a frame. A chassis is arranged at the lower end of the frame, and a welding torch is arranged at the upper end of the frame. A lifting drive mechanism is arranged at the upper end of the frame, and the lifting drive mechanism is connected to the welding torch. A welding station is arranged on the chassis directly opposite the welding torch, and the welding station is used to position the rotor compressor. Two vertical columns are arranged on the open side of the frame. A slideway is installed on each column, and a protective cover is installed on the two slideways. A linear drive mechanism is installed at the upper end of each of the two columns, and the output end of the linear drive mechanism is connected to the protective cover.

[0005] Further, the protective cover is composed of two side plates and a slag baffle. One end of each of the two side plates is slidably connected to the corresponding slideway, and both ends of the slag baffle are connected to the upper ends of the two side plates.

[0006] Further, when the protective cover is lowered to the lowest position, the slag baffle covers the upper half of the shell of the rotor compressor. When the protective cover is lifted to the highest point, the lower edge of the slag baffle is higher than the top height of the compressor.

[0007] Further, the lifting drive mechanism adopts air cylinders, and the two air cylinders act synchronously.

[0008] Further, the width of the slag baffle is 15 - 30 cm.

[0009] The utility model has the following advantages compared with the prior art: by providing a movable protective cover, during the welding process of the compressor, the slag baffle is used to block the splashing of welding slag outwards, thereby avoiding the situation that the welding slag flies into the interior of the compressor housing.

[0014] See Figures 1-2 , this embodiment provides a splash-proof welding machine for sealing and welding the housing of a rotary compressor 9, including a frame 1, a chassis 7 is provided at the lower end of the frame 1, a welding torch 6 is provided at the upper end of the frame 1, a lifting drive mechanism is provided at the upper end of the frame 1, the lifting drive mechanism is connected to the welding torch 6, a welding station is provided on the chassis 7 directly opposite to the welding torch 6, the welding station is used to position the rotary compressor 9, two vertical columns 2 are provided on the open side of the frame 1, a slideway 4 is installed on each column 2, a protective cover 5 is installed on the two slideways 4, and a linear drive mechanism is installed at the upper end of each of the two columns 2, and the output end of the linear drive mechanism is connected to the protective cover 5.

[0015] Further, the protective cover 5 is welded and formed by two side plates 52 and a slag baffle 51, one ends of the two side plates 52 are respectively slidably connected to the corresponding slideways 4, and both ends of the slag baffle 51 are connected to the upper ends of the two side plates 52.

[0016] Further, when the protective cover 5 is lowered to the lowest position, the slag baffle 51 covers the upper half of the housing of the rotary compressor 9, and when the protective cover 5 is lifted to the highest position, the lower edge of the slag baffle 51 is higher than the top height of the compressor 9.

[0017] Further, the lifting drive mechanism adopts cylinders 3, and the two cylinders 3 act synchronously.

[0018] Furthermore, the width of the slag baffle 51 is 15 - 30 cm. The working principle of the present utility model is as follows: When there is no compressor 9 in the welding machine, the two cylinders 3 are in the retracted state. At this time, the protective cover 5 is at the highest point. The manipulator 10 picks up a rotor compressor 9 from the assembly line 8 and then places it on the chassis 7 of the welding machine from the open side of the welding machine. The chassis 7 rotates to send the compressor 9 to the welding station inside the welding machine. Since the lower edge of the slag baffle 51 is higher than the top height of the compressor 9, there will be no interference. When the compressor 9 reaches the welding station, the two cylinders 3 act synchronously to extend, causing the protective cover 5 to move downward along the slideway 4. When the protective cover 5 moves to the lowest point, the slag baffle 51 just blocks the welding part of the rotor compressor 9. All the splashed welding slag generated during the welding process is blocked by the slag baffle 51, so it will not splash onto the assembly line 8 and will not affect the compressor 9 on the assembly line 8.
