Embodiment 1

[0039] Such as Figure 1-9 As shown, this embodiment provides a telescopic motor with precise control of the extension length of the main shaft, including a casing 1 and a motor 4 placed in the casing, a top plate 5, a chassis 2, a lead screw 6, a main shaft 3 and a piston 16;

[0040] The motor 4 is fixedly connected to the top plate 5, the lead screw 6 runs through the piston 16 and is threadedly connected with the piston 16, the upper and lower ends of the lead screw 6 are respectively connected to the top plate 5 and the chassis 2, and the output shaft of the motor 4 is connected to the upper end of the lead screw by transmission. The top of the main shaft 3 is fixedly connected with the bottom surface of the piston 16 , and the bottom end of the main shaft 3 extends out of the casing 1 after penetrating the chassis 2 . The center of the chassis 2 is provided with a through hole 11 through which the main shaft 3 protrudes.

[0041] Specifically, the entire casing 1 is cyl...

Embodiment 2

[0051] A working method of a telescopic motor that precisely controls the extension length of the main shaft, using the telescopic motor provided in Embodiment 1, includes the following steps:

[0052] 1) Control the servo motor to start the operation through the external controller (the servo motor is connected to the external controller circuit), and the servo motor drives the driving gear to rotate through the reduction mechanism;

[0053] 2) The driving gear meshes with the driven gear, thereby driving the driven gear and the lead screw 6 to rotate synchronously;

[0054] 3) The lead screw 6 rotates, so that the piston 16 is subjected to an upward or downward force, and moves upward or downward along the path limited by the guide post 7, and finally drives the main shaft 3 to move up and down.

Abstract

The invention relates to a telescopic motor capable of accurately controlling the extension length of a main shaft and application of the telescopic motor. The telescopic motor comprises a machine shell, a motor body, a top disc, a bottom disc, a lead screw, the main shaft and a piston, wherein the motor body, the top disc, the bottom disc, the lead screw, the main shaft and the piston are arranged in the shell. The motor is fixedly connected with the top disc, and lead screw penetrates through the piston and is in threaded connection with the piston; the upper end and the lower end of the lead screw are connected with the top disc and the bottom disc respectively, an output shaft of the motor is in transmission connection with the upper end of the lead screw, the top end of the main shaft is fixedly connected with the bottom face of the piston, and the bottom end of the main shaft penetrates through the bottom disc and then extends out of the machine shell. According to the invention, a servo motor is matched with a gear reducing mechanism and the lead screw, so that the axial action of the motor spindle can be accurately controlled, namely the extension length of the spindle can be accurately controlled. According to the servo motor, the gear reducing mechanism is matched with the lead screw, so that the motor has large rated load; meanwhile, the gear reducing mechanism is matched with the lead screw, so that the motor has stable output force; and the gear reducing mechanism is matched with the lead screw, so that the motor has a large main shaft stroke and a long telescopic stroke.

Description

technical field [0001] The invention relates to a telescopic motor for precisely controlling the extension length of a main shaft and an application thereof, belonging to the technical field of telescopic motors. Background technique [0002] At present, the commonly used motor is mainly composed of a casing, a stator and a rotor arranged in the stator. The front end and the rear end of the casing are respectively provided with a front end cover and a rear end cover. The motor with this structure has poor winding performance and poor layout. The distance is uneven, which greatly reduces the work efficiency, especially the precision of the motor work. [0003] Chinese patent document CN102158001A discloses a motor and an electric spindle whose rotor can move freely and telescopically. It is provided with a stator in the casing, and the rotor, the rotor shaft, and the front and rear ends of the rotor shaft are equipped with bearings and bearing casings that are longer than the...
