Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of welding clamping devices, and in particular to a welding clamping device for the end cap of a compressor cylinder. Background Technology
[0002] The air conditioner compressor plays the role of compressing and driving the refrigerant in the air conditioner refrigerant circuit. It draws the refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area to cool and condense it. The heat is then dissipated into the air through the heat sink, and the refrigerant changes from a gaseous state to a liquid state, increasing the pressure. As for the compressor body, during the manufacturing process, the body and the end cover need to be welded together.
[0003] However, the current method of fixing the cylinder during welding is not flexible or convenient enough, and sometimes the fixing is not stable enough, causing shaking during welding and affecting the welding quality. In addition, when welding the end cap to the cylinder, it is difficult to align the central axes of the two, resulting in eccentricity after welding, which affects the subsequent operation of the compressor cylinder. In order to overcome these disadvantages, this utility model provides a compressor cylinder end cap welding clamping device. Utility Model Content

A first cylinder 11 is fixedly connected to the upper end of the connecting housing 10. A pressure plate 12 is rotatably connected to the output end of the first cylinder 11. The first cylinder 11 drives the pressure plate 12 to move, which can apply pressure to the end cover, thereby pressing and fixing the cylinder body and the end cover.
[0025] As shown in the figure, a pointer 4 is fixedly connected to the outside of the first rotating shaft 13 on one side, and a scale 5 is fixedly connected to one end of the support frame 2. The tilt angle can be observed through the pointer 4 and the scale 5, thereby adjusting the tilt angle of the cylinder and the end cap.

A worm 22 is fixedly connected to one end of the second rotating shaft 21, and a crank 23 is fixedly connected to the other end of the second rotating shaft 21. A worm wheel 24 is fixedly connected to a first rotating shaft 13 located on one side. The worm 22 and the worm wheel 24 are meshed together. By turning the crank 23, the worm 22 on the second rotating shaft 21 is driven to rotate. Through the transmission between the worm wheel 24 and the worm 22, the first rotating shaft 13 can be driven to rotate, which can drive the support housing 3 to rotate.
[0027] As shown in the figure, the clamping assembly 8 includes a slide rail 14 fixedly connected to one side of the turntable 7. Slider 17 is slidably connected to both ends of the inner side of the slide rail 14. Arc-shaped clamping plates 18 are fixedly connected to the inner side of each slider 17.
