Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 5 As shown, the assembly fixture for processing precision metal sheet metal structural parts for air-energy electrical equipment proposed in the utility model includes a base plate 100, a mounting frame 101, a fixing structure 200 and a control structure 300. The mounting frame 101 is arranged above the base plate 100, and the fixing structure 200 includes a mounting cylinder 203, a mounting column 205 located inside the mounting cylinder 203, a piston 204 located at the upper end of the mounting column 205, a compression spring 212 located at the upper end of the piston 204 and connected to the inner wall of the upper end of the mounting cylinder 203, a pressure block 207 located at the lower end of the mounting column 205, and a supporting platform 209 located at the upper end of the mounting frame 101.

[0025] A sleeve plate 211 is sleeved on the outer wall of the installation tube 203 , and one end of the sleeve plate 211 is connected to the inner wall of one side of the installation frame 101 . The four corners of the lower end of the installation frame 101 are all provided with installation holes 102 .

[0026] The upper and lower ends of the mounting cylinder 203 are embedded with a sleeve 1 202 and a sleeve 206 . The upper end of the piston 204 is provided with a guide rod 1 201 slidably inserted into the sleeve 1 202 . The lower end of the mounting column 205 is slidably inserted into the sleeve 206 .

[0027] A bearing 210 is embedded and installed inside the upper end of the pressure plate 308 , and the lower end of the mounting column 205 is rotatably installed inside the bearing 210 .

[0028] A rotating rod 208 is disposed at the lower end of the supporting platform 209 , and the lower end of the rotating rod 208 is rotatably mounted inside the upper end of the mounting frame 101 .

[0029] Based on the implementation steps of Example 1: the precision sheet metal structural parts are assembled in the processing room, and are pressed and held on the pressure block 207 box carrier. Through the rotatable characteristics, the angle can be adjusted when the positioning is fixed. When the precision sheet metal structural parts are rotated to spray on different surfaces, the rotatable fixture is flexible to use when assembling the fixing parts or sleeve the shell inside the precision sheet metal structural parts.

[0030] When used for cutting, welding and drilling, the bearing 210 and the rotating rod 208 are not assembled due to the need for stability, so that the supporting platform 209 and the pressing block 207 are fixed, so that the precision metal sheet metal structure can remain stable during cutting, welding and drilling.

[0031] like Figure 1-Figure 5 As shown, the assembly fixture for processing precision metal sheet metal structural parts for air energy electrical equipment proposed by the utility model is compared with the first embodiment, and this embodiment also includes:
