[0002] In the thermocouple sensors of aero-engines, the mounting base is the main structural component, such as... Figure 1 As shown, the structure is generally complex in shape, and the component is usually machined from a casting. Most surfaces of the casting have allowances that require additional machining. The outer diameter and inner hole of the rotating part can be machined by turning, while the rest requires milling. However, the existing mounting base does not have a straight edge for clamping and positioning during milling. Therefore, multiple clamping is required during machining. Since the deformation of each casting is different, it is necessary to readjust and machine after each clamping, resulting in long auxiliary time and low utilization of CNC milling equipment. However, if a conventional milling machine is used to machine this part, it will result in low efficiency, difficulty in ensuring production cycle, and poor consistency of machining quality. Therefore, there is an urgent need for a CNC milling fixture for the mounting base to solve the above problems. Utility Model Content

A positioning screw is located in the positioning hole, vertically passing through the center of the mounting bracket body and extending into the positioning hole. The positioning screw and the positioning hole lock and fix the center of the mounting bracket body. The support screw is located between the mounting bracket body and the base plate, supporting the suspended portion of the mounting bracket body. The sliding positioning plate has a limit hole and a limit screw located inside the limit hole. The limit screw passes through the limit hole and extends into the base plate, fixing the sliding positioning plate and restricting its movement.

[0006] Further, the bottom plate is provided with three groups of corresponding positioning holes and sliding grooves, which can process three mounting seat bodies at the same time, and the distance between two adjacent mounting seat bodies in the three mounting seat bodies is fixed.
