[0002] The air-conditioning compressor plays the role of compressing and driving the refrigerant in the air-conditioning refrigerant circuit. The refrigerant is extracted from the low-pressure area, compressed, and then sent to the high-pressure area for cooling and condensation. The heat is dissipated into the air through the heat sink, and the refrigerant also changes from gas to liquid, and the pressure increases. As for the compressor cylinder, during the production process, it is necessary to weld the cylinder and the end cover. During welding, the fixing method of the cylinder is not flexible and convenient enough. Sometimes, it will shake during welding due to insufficient stability of the fixation, affecting the quality of welding.

For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0021] Reference Figure 1-Figure 4 A compressor cylinder welding positioning mechanism comprises a base 1, a cylinder 7 and an end cover 14. A conical seat 2 is fixed to the base 1 by bolts, and the cylinder 7 is sleeved on the conical seat 2 so that the cylinder 7 and the conical seat 2 are on the same central axis. Slides 8 are provided on both sides of the base 1, and slides 4 are slidably connected in the slides 8. A limiting component for fixing the cylinder 7 is provided on the slide 4 to keep the cylinder 7 stable. A driving component for moving the slide 4 is provided on the base 1 so that the limiting component can adapt to fixing cylinders 7 of different diameters. A fixing frame 5 is fixed to the base 1 by bolts, and a conical cylinder 6 is provided on the top of the fixing frame 5, and the conical cylinder 6 and the conical seat 2 are on the same central axis. The end cover 14 is arranged in the conical cylinder 6, and an adsorption component for fixing the end cover 14 is provided in the conical cylinder 6.

[0022] In the utility model, the limiting component is a positioning roller 12, one side of the two slides 4 is provided with a limiting frame 11, both ends of the limiting frame 11 are rotatably connected with the positioning roller 12, and the positioning roller 12 is in contact with the outer wall of the cylinder 7, one side of the two slides 4 is penetrated and slidably connected with a slide bar 9, the limiting frame 11 is fixed to one end of the slide bar 9, the circumferential outer walls of the two slide bars 9 are sleeved with springs 10, and the two ends of the spring 10 are respectively fixed to the slide 4 and the slide bar 9, the driving component is a bidirectional screw 13, and the bottom of the base 1 is rotatably connected with The bidirectional screw 13 passes through the two slides 4 and is threadedly connected with the two slides 4. When the bidirectional screw 13 is rotated, the two slides 4 move toward each other, and the movement of the slide 4 causes the positioning roller 12 to contact the outer wall of the cylinder 7. When the slide 4 continues to move, the cylinder 7 squeezes the positioning roller 12, causing the slide bar 9 on the limit frame 11 to move along the slide 4. At this time, the spring 10 is forced to contract, causing the positioning roller 12 to fit tightly with the cylinder 7, and then the cylinder 7 is locked by multiple positioning rollers 12.

[0023] In the utility model, the adsorption component is a suction cup 15, and a second electric telescopic rod 18 is fixed to the top inner wall of the conical tube 6 by bolts. An air pump 16 is fixed to one end of the second electric telescopic rod 18 by bolts. The suction cup 15 is fixedly connected to the bottom of the air pump 16, and the suction cup 15 is adsorbed with the end cover 14, and the end cover 14 is placed in the conical tube 6. At this moment, the end cover 14 and the conical tube 6 are kept on the same axis, and the second electric telescopic rod 18 is started. The second electric telescopic rod 18 is extended to move the adsorption component downward. After the suction cup 15 contacts the end cover 14, the air pump 16 is started, and then the suction cup 15 generates suction to tightly adsorb the end cover 14.

[0024] In the utility model, a first electric telescopic rod 17 is fixed to the top of the fixed frame 5 by bolts, and one end of the first electric telescopic rod 17 is fixed to the conical cylinder 6. The first electric telescopic rod 17 is extended to move the conical cylinder 6 downward, and the end cover 14 is lowered to contact with the cylinder body 7 and then stops. At this moment, the cylinder body 7 and the end cover 14 are on the same central axis, so that the two can be welded by welding equipment.

[0025] In the utility model, support plates 3 are fixed to the bottoms of both sides of the base 1 by bolts.

[0026] Working principle: when the end cover 14 needs to be welded to the cylinder 7, first put the cylinder 7 on the conical seat 2, and then rotate the bidirectional screw 13. The rotation of the bidirectional screw 13 causes the two slides 4 to move toward each other, and the movement of the slide 4 causes the positioning roller 12 to contact the outer wall of the cylinder 7. When the slide 4 continues to move, the cylinder 7 squeezes the positioning roller 12, causing the slide bar 9 on the limit frame 11 to move along the slide 4. At this time, the spring 10 is forced to contract, causing the positioning roller 12 to fit tightly with the cylinder 7, and then the cylinder 7 is locked by multiple positioning rollers 12;

[0027] The end cap 14 is placed in the conical cylinder 6. At this moment, the end cap 14 and the conical cylinder 6 are kept on the same axis. The second electric telescopic rod 18 is started. The second electric telescopic rod 18 is extended to move the adsorption assembly downward. After the suction cup 15 contacts the end cap 14, the suction pump 16 is started. Then the suction cup 15 generates suction to tightly adsorb the end cap 14. Since the conical seat 2 and the conical cylinder 6 are on the same central axis, the fixed cylinder body 7 and the end cap 14 are on the same central axis at this moment. Then the first electric telescopic rod 17 is started. The first electric telescopic rod 17 is extended to make the conical cylinder 6 move downward, the end cover 14 descends to contact with the cylinder body 7 and then stops, and then the contact point of the end cover 14 and the cylinder body 7 is welded by external welding equipment. After the welding is completed, the suction pump 16 stops working, the second electric telescopic rod 18 retreats to disengage the suction cup 15 from the end cover 14, the first electric telescopic rod 17 retreats to make the conical cylinder 6 rise as a whole, and then the bidirectional screw 13 is rotated in the opposite direction, the two slides 4 move in the opposite direction to reset, the positioning roller 12 is disengaged from the cylinder body 7, and the cylinder body 7 is removed from the conical seat 2.
