[0002] The servo mechanism is a two-axis rotation servo mechanism. While the outer frame's main shaft drives the inner frame to rotate, the pitch frame inside the inner frame can also rotate around the axis. The inner and outer frames are connected by a rotary joint. During assembly, the rotary joint mounting surface needs to be leveled, and the flatness must be less than 0.05mm. In addition, to facilitate assembly and adjustment, a connector is designed between the rotary joint and the mounting base. After the rotary joint is leveled, the connector needs to be positioned and punched, and a positioning pin needs to be installed to ensure the connection accuracy and stability between the rotary joint and the base.

[0003] Existing leveling methods rely on manual leveling, and the position of the rotating joints is secured by caulking and gluing during the leveling process. This makes leveling difficult and time-consuming. Furthermore, these fixing methods are unreliable, and after leveling, they are unable to provide effective support for drilling, posing a risk of operational errors. This invention aims to address these issues in actual production, providing a tooling device that maximizes assembly accuracy while improving work efficiency.

[0023] The base 1 is designed as a hollow box-shaped bracket, with a set of pitching positioning holes designed. Cooperating with the pitching positioning pin 9, the pitching direction of the two-axis servo motor rotary joint structure 5 can be locked, simplifying the leveling work; inside the first positioning surface 3, horizontal positioning holes are designed, and the inherent horizontal holes on the two-axis servo motor rotary joint structure 5 can be used for pre-positioning, reducing the horizontal leveling range; inside the first positioning surface 3, horizontal adjustment threaded holes are designed, and the adjusting screw 7 can be used to level the two-axis servo motor rotary joint structure 5 horizontally, realizing a controllable process; on the base 1, there are multiple profiling relief structures 2 designed to avoid part interference during clamping and provide relief protection for the wire harness; the pitching positioning pin 9 can lock the parts using the inherent pitching hole positions of the two-axis servo motor rotary joint structure 5, simplifying the leveling work; the horizontal positioning pin 6 can be pre-positioned using the inherent horizontal holes on the two-axis servo motor rotary joint structure 5, reducing the horizontal leveling range; the adjusting screw 7 can horizontally adjust the two-axis servo motor rotary joint structure 5, realizing stepless adjustment and a controllable process; the fastening bolt 8 can lock the two-axis servo motor rotary joint structure 5 in the horizontal and pitching directions after leveling, facilitating the subsequent drilling and assembly steps, avoiding positioning failure after disassembly and assembly, and ensuring the assembly accuracy of the parts;
