[0030] As shown in Figure 3 , the adjusting mechanism 4 includes a column 41, the lower end of which is rotatably installed with the lower end of the inner cavity of the shell 3, and the lower end of the column 41 is externally fixed with a pulley one 42, the lower right end of the inner cavity of the shell 3 is fixedly connected with a motor one 43, the top end of the output rod of the motor one 43 is fixedly provided with a pulley two 44, the pulley one 42 and the pulley two 44 are sleeved with a belt 45, and the upper end of the shell 3 is externally fixed with an annular slide rail 46, and the lower end of the mounting frame 5 is externally circularly distributed with a plurality of slide blocks 47.
[0031] The top end of the column 41 extends out of the inside of the shell 3, and the top end of the column 41 is fixedly connected with the lower end of the mounting frame 5.
[0032] The inside of the slide rail 46 matches the lower end of the slide block 47 and is slidably connected.
[0033] In the scheme, when the mounting frame 5 rotates, the slide block 47 will slide synchronously in the slide rail 46, so as to ensure the stable operation of the mounting frame 5 during rotation and avoid shaking or deviation.
[0034] As shown in Figures 4-5 , the fixing mechanism 7 includes a groove 71, which is arranged in the middle of the inner cavity of the mounting frame 5, and the two sides of the inner cavity of the mounting frame 5 are provided with a communication groove 72, the middle of the groove 71 is fixedly provided with a double-shaft motor 73, the two sides of the double-shaft motor 73 are transmissionally installed with a lead screw 74, the outer thread of the lead screw 74 is installed with a threaded seat 75, and the front and rear ends of the threaded seat 75 are fixedly provided with a linkage plate 76.
[0035] The inner cavity bottom end of the communication groove 72 is fixedly installed with a cross bar 77, the top end of the cross bar 77 is fixedly connected with a limiting block 78 on both sides, the outer side of the cross bar 77 is slidably installed with a sleeve frame 79, the upper and lower surfaces of the sleeve frame 79 are provided with a limiting groove 710, the top end of the sleeve frame 79 is fixedly connected with a stand 711 on both sides, and the top end of the stand 711 is fixedly provided with a clamping plate 712.

[0039] The working principle of the machining fixture for the heat exchanger shell will be explained in detail below.
[0040] like Figures 1-5 As shown, when using the machining fixture for the heat exchanger shell, the heat exchanger shell can first be placed on the mounting bracket 5. Then, the dual-axis motor 73 can be started, driving the lead screws 74 on both sides to rotate. The rotating lead screws 74 can drive the threaded seats 75 on both sides to gradually move closer, so that the moving threaded seats 75 can drive the sleeve 79 to move synchronously through the linkage plate 76. The sleeve 79 can slide synchronously on the crossbar 77, and the sleeves 79 on both sides can drive the upright frame 711 to gradually move closer. The upright frame 711 drives the clamping plate 712 to move synchronously, so that the clamping plate 712 can clamp the heat exchanger shell on the mounting base 1, making it less prone to loosening. To avoid affecting processing efficiency, when it is necessary to adjust the position of the heat exchanger during processing, motor 43 can be started. Motor 43 drives pulley 44 to rotate, and pulley 44, in turn, drives pulley 42 to rotate synchronously via belt 45. When pulley 44 rotates, it will directly drive column 41 to rotate together. The top of column 41 is securely connected to the clamped heat exchanger shell through mounting base 1. As column 41 rotates, mounting base 1 also moves, thereby driving the heat exchanger shell to rotate synchronously and change position. This allows for adjustment of the position of the heat exchanger during processing, facilitating comprehensive processing of the shell and improving the processing efficiency of the heat exchanger shell.
[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
