[0018] Embodiment 1:

[0019] See also Figure 1-3 , a compressor housing automatic welding equipment, including a spot welding machine 1, a base 2 is provided on the workbench surface of the spot welding machine 1, and a clamping assembly 3 for fixing the compressor housing is provided on the base 2. The clamping assembly 3 includes a bottom plate 5, a slide plate 6, a clamping block 7, a bracket 8 and a first cylinder 9. The bottom plate 5 is fixed on the base 2, and a slide groove 13 is symmetrically opened on the bottom plate 5. There are two slide plates 6, and the two slide plates 6 are slidably arranged inside the slide groove 13. A limit block 14 for limiting the slide groove 13 and thus limiting the slide plate 6 is fixedly connected to the base 2. There are two clamping blocks 7 and they are respectively arranged on the two slide plates 6. The outer side of the clamping block 7 is provided with an elastic friction pad 15, which ensures the friction between the clamping block 7 and the compressor housing while avoiding damage to the side of the compressor housing. The bracket 8 is symmetrically installed at both ends of the bottom plate 5, and the first cylinder 9 is installed on the bracket 8, and the first cylinder 9 passes through the bracket 8 and one end of the slide plate 6 and is fixedly connected.

[0020] The clamping assembly 3 is provided with an auxiliary assembly 4 for positioning and fixing the machine foot. The auxiliary assembly 4 includes a fixing frame 10 and a second cylinder 11. A support plate 17 is slidably provided on the bracket 8. The support plate 17 is fixed in position by bolts 18 and the bracket 8. By adjusting the height of the support plate 17, the height of the second cylinder 11 can be adjusted. It is suitable for compressor housings of different models. The second cylinder 11 is installed on the support plate 17. The second cylinder 11 passes through the bracket 8. The fixing frame 10 is fixed at the output end of the second cylinder 11.
