[0021] The following is a detailed description of the specific embodiments of the present utility model, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.

[0022] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or variations thereof such as "including" or "having" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0023] As Figure 1-6 shown, a steel sleeve assembly tool for a controller chassis includes a sleeve 1, a screw 2, a guide rod 3, and a punch 4; a through hole 10 is provided at the center of the sleeve 1, and a steel sleeve threaded hole 50 and a key pin 51 are provided on the steel sleeve 5. The ends of the screw 2 and the guide rod 3 are provided with M6 threads, and the dimensions of the screw 2 and the guide rod 3 are matched with the through hole 10 and the steel sleeve threaded hole 50; a positioning mechanism 11 is provided on the end face of the sleeve 1. The positioning mechanism 11 includes an annular protrusion 12 and a key pin positioning hole 13. The annular protrusion 12 is provided on the end face of the sleeve 1. The annular protrusion 12 is concentric with the through hole 10. The annular protrusion 12 is matched with the plane position of the steel sleeve threaded hole opening. The height of the annular protrusion 12 is 0.4 mm. Key pin positioning holes 13 are symmetrically arranged in the circumferential direction of the annular protrusion 12, and the key pin positioning holes 13 are matched with the positions of the key pins 51; a guide hole 40 is provided in the punch 4, and the size of the guide hole 40 is matched with the guide rod 3. The end face of the punch 4 is an annular end face 41, and the outer circumference of the annular end face 41 corresponds to the outside of the key pin 51; scale lines 30 are provided on the guide rod 3, and the height of the scale lines 30 is the installation-in-place height of the steel sleeve 5.
