Description

Technical Field

[0001] The invention relates to the field of welding, and in particular to a welding fixture for an automobile battery box. Background Art

[0002] The market share of new energy vehicles is increasing, and the performance requirements for vehicles are also getting higher and higher, especially the endurance, safety and charging and discharging speed. This requires that the power battery capacity of new energy vehicles is getting larger and larger, and the reliability and stability of the battery are getting better and better. The carrier of the power battery is the battery box, and the lightweight and reliability requirements of the battery box are also constantly increasing. At present, most battery boxes are made of aluminum alloy materials through welding. There are many welding positions in the battery box.

The first cylinder 25 is fixed on the first cylinder seat 23 to drive the first clamping block 28 and the second clamping block 29 to rotate on the first cylinder seat 23. After the first clamping block 28 and the second clamping block 29 rotate, the first part 34 can be clamped or loosened.The second cylinder seat 24 is used to install the second cylinder 26 and the third cylinder 27. The second cylinder 26 drives the third clamping block 30 to clamp or loosen one side of the second part 35 from one side.

Under the action of the detection spring 48 and the limit ring 49, the detection rod 47 extends upward, and the detection rod 47 will not contact the proximity switch 50. When the detection nut 51 exists, the detection nut 51 presses the detection rod 47, and the detection rod 47 will be detected by the proximity switch 50. At this time, it proves that the detection nut 51 exists. When the detection nut 51 does not exist, the detection rod 47 will not be pressed, nor will it be detected by the proximity switch 50. At this time, it proves that there is no detection nut 51 and the detection nut 51 needs to be installed.

The first clamping component 53 is provided with a third detection sensor 56 for detecting the third part 58, and the second clamping component 54 is provided with a fourth detection sensor 57 for detecting the fourth part 59. Among them, the third part seat 52 is used to support the third part 58. The fourth part 59 and the fifth part 60 need to be welded on the third part 58. The first clamping component 53, the second clamping component 54, the third detection sensor 56 and the fourth detection sensor 57 are all existing technologies and are electrically connected to the control center. When the third detection sensor 56 detects the third part 58, the signal is transmitted to the control center, and the control center controls the first clamping component 53 to clamp the third part 58. When the fourth detection sensor 57 detects the fourth part 59, the signal is transmitted to the control center, and the control center controls the second clamping component 54 to press the fourth part 59 onto the third part 58. When the third part 58 and the fourth part 59 are welded, the welding robot will be blocked by the third clamping component 55. Therefore, after the welding between the third part 58 and the fourth part 59 is completed, the third clamping component 55 presses the fifth part 60 onto the third part 58 for welding.

[0038] In some embodiments, the third clamping component 55 includes a flipping cylinder 61, a clamp seat 62, a card seat 63, a positioning end 64, a clamping end 65, a clamping rod 66, a clamping cylinder 67 and a fifth detection sensor 68.

Among them, the flip cylinder 61, the pressing cylinder 67 and the fifth detection sensor 68 are all existing technologies. The solenoid valve controlling the flip cylinder 61, the solenoid valve controlling the pressing cylinder 67 and the fifth detection sensor 68 are all electrically connected to the control center. The fifth detection sensor 68 is used to detect whether the fifth part 60 exists on the fixture seat 62. The fixture seat 62, the clamp seat 63, the positioning end 64, the pressing end 65, the pressing rod 66 and the pressing cylinder 67 are used in conjunction to fix the fifth part 60 on the fixture seat 62, and the fifth part 60 is relaxed after welding. After the welding between the third part 58 and the fourth part 59 is completed, the flip cylinder 61 is controlled to press the fifth part 60 on the third part 58 for welding. After the welding is completed, the pressing cylinder 67 first relaxes the fifth part 60, and then controls the flip cylinder 61 to leave the fifth part 60.
