Background technique

The servo drive is an important factor affecting the motion characteristics of machine tools. Its installation accuracy directly affects the motion accuracy of machine tools. Generally speaking, the most important thing in the installation of the servo drive is the relative position of the motor seat, nut seat, and bearing seat, which is often referred to as the "three seats concentric" in the machine tool assembly process.

The motor seat is one of the important parts in the servo transmission equipment of machine tools. The traditional motor seat is shown in Figure 1. As the main support end of the screw, it is mainly used to install the servo motor and bearing. The machining accuracy and relative position relationship of the motor and bearing mounting surfaces directly affect the assembly accuracy. The traditional motor seat has the following disadvantages during the assembly process: 1. The motor mounting surface and the bearing mounting surface are on the same part.

The bearing end cover can only be installed and fixed from the side, which is not easy to operate; 3. When adjusting the three-seat installation accuracy and the screw rotation accuracy, it is inconvenient to detect due to the influence of the motor mounting part in front of the motor seat; 4. During maintenance, since the bearing is located inside the motor seat, it is not easy to disassemble.
