[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Example

[0028] To address the low work efficiency caused by manually positioning and pressing multiple welding pieces B onto pressure vessel component A before welding in existing technologies, reference is made to... Figures 1-6 As shown, this application discloses a welding equipment for an air compressor pressure vessel, including a base plate 10, a pressure vessel component clamping mechanism 20, and a welding piece clamping mechanism 30;

[0029] The pressure vessel component clamping mechanism 20 includes a support rod 21, a connecting block 22 disposed on the support rod 21, a shaft hole opened on the connecting block 22, a torsion spring 23 installed in the shaft hole, a rotating shaft 24 passing through the torsion spring 23 and extending outward from the shaft hole, and a pressure block 25 fixed on the rotating shaft 24.

[0030] The welding sheet clamping mechanism 30 includes a gantry bracket 31 on the base plate 10, a cylinder 32 at the bottom of the crossbeam of the gantry bracket 31, a triangular chuck 33 connected below the piston rod of the cylinder 32, three finger grippers 35 respectively located below the three support corners of the triangular chuck 33, and two grippers 35 connected to the two output parts of each finger cylinder 34.

[0031] Based on the above structure, in the specific implementation process, the operator first places the pressure vessel component to be welded on the base plate 10, and operates the pressure block 25 to rotate so that it presses down on the pressure vessel component. Then, the cylinder 32 is controlled to drive the triangular chuck 33 to descend. At this time, the two jaws 35 of the several finger cylinders 34 will press the welding piece they are clamping onto the pressure vessel component. In this way, the operator or welding robot can quickly perform welding, which improves work efficiency and has high application value.

[0032] To enable positioning of various pressure vessel components, the base plate 10 has three inclined slots 11 arranged in a circular array around its center. Positioning pins 40 are adjustablely embedded in each of the three inclined slots 11. Depending on the size of the pressure vessel component, the operator simply screws the three positioning pins 40 into different positions within the three inclined slots 11. During positioning, these three positioning pins 40 will be in contact with the inner wall of the pressure vessel component. Correspondingly, this application also includes a mounting plate 36 on the top of the finger cylinder 34. Two grooves 331 are respectively opened on the three corners of the triangular chuck 33, and bolts are installed in each of the two grooves 331 to fix the mounting plate 36. In other words… The finger cylinder 34 can be adjusted and fixed at any position on the support of the triangular chuck 33. Depending on the size of the pressure vessel component, the finger cylinder 34 can precisely press the welding piece onto pressure vessel components of different sizes. In addition, the pressure block 25 of this application has an oblong hole 251. The end of the rotating shaft 24 connected to the oblong hole 251 has an external thread. The rotating shaft 24 passes through the oblong hole 251 and is fixed to the pressure block 25 with a nut 26 on the external thread. When pressing different pressure vessel components, the rotating shaft 24 is inserted into different positions of the oblong hole 251 and fixed to the pressure block 25 with the nut 26, which can meet the pressing needs of pressure vessel components of different sizes.

[0033] In this embodiment, the pressure block 25 has protrusions 27 on its pressing surface, so that the pressure block 25 can apply point pressure to the pressure vessel component, resulting in a better pressing effect.

[0034] A vertical plate 37 is provided on one side of the finger cylinder 34 between two grippers 35. A support block 38 is provided on the vertical plate 37 extending between the two grippers 35. A positioning pin 39 is provided at the bottom of the support block 38, which enables precise positioning of the welding piece and has high practicality.

[0035] In order to position and install the torsion spring 23, this application provides a stepped groove 221 on the outer side of the pressure block 25, which is coaxial with the shaft hole pressure, and the torsion spring 23 is embedded in the stepped groove 221.
