Embodiment 1

[0047] Such as figure 1 , figure 2 , Figure 4 , Figure 5 As shown, the main shaft 2 is provided with a slideway 201 extending in the axial direction; the rotating shaft of the rotating drive rotor 301 can move in translation along the slideway 201; the rotating drive coil 4 drives the rotating drive rotor 301 to rotate by means of electromagnetic excitation, and then rotates and drives the rotor The rotating shaft 301 exerts force on the slideway 201 to drive the main shaft 2 to rotate.

[0048] Neither the first positioning mechanism nor the second positioning mechanism in the second chamber tensions the sleeve and the main shaft at the same time. The magnetic pole directions of the permanent magnets in the first chamber as the rotating and driving rotors are the same, and the permanent magnets are installed on both sides of the main shaft through the rotor shaft; the rotating driving mechanism as the driving body includes four electromagnetic coils, which are divided i...

Embodiment 2

[0052] Such as image 3 As shown, the main shaft 2 is provided with a slideway 201 extending in the axial direction; the rotating shaft of the rotating drive rotor 301 can move in translation along the slideway 201; the rotating drive coil 4 drives the rotating drive rotor 301 to rotate by means of electromagnetic excitation, and then rotates and drives the rotor The rotating shaft 301 exerts force on the slideway 201 to drive the main shaft 2 to rotate.

[0053]Neither the first positioning mechanism nor the second positioning mechanism in the second chamber tensions the sleeve and the main shaft at the same time. The magnetic pole directions of the permanent magnets in the first chamber as the rotating drive rotor are the same, and the permanent magnets are sheathed on the main shaft; the rotating drive coil as the driving body includes four electromagnetic coils, which are divided into left and right, upper and lower groups from the axial view. When the left and right grou...

Embodiment 3

[0057] As shown in FIG. 6 and FIG. 7 , the rotary drive rotor 301 is tightly sleeved on the main shaft 2 ; the rotary drive coil 4 drives the rotary drive rotor 301 to rotate by means of electromagnetic excitation, and then the rotary drive rotor 301 drives the main shaft 2 to rotate.

[0058] Neither the first positioning mechanism nor the second positioning mechanism in the second chamber tensions the sleeve and the main shaft at the same time. The permanent magnets in the first chamber are fan-shaped permanent magnets as fan-shaped magnets, and the magnetic poles of adjacent permanent magnets are in opposite directions, and all the permanent magnets form a magnetic turntable and are installed on the main shaft. The driving body includes 6 electromagnetic coils, but is not limited to this number. The 6 electromagnetic coils are divided into three groups and arranged in the middle of the front and rear magnetic turntables. When the three groups of electromagnetic coils are su...

Abstract

The invention provides a controllable rotary feed system and a control method. The controllable rotary feed system comprises a sleeve (1), a main shaft (2), a rotary drive mechanism (3), a rotary drive coil (4), a feed drive mechanism (5) , and a feed drive coil (6). A rotary drive rotor (301) is driven by the rotary drive coil (4) to drive the main shaft (2) to rotate relative to the sleeve. A feed drive rotor (601) is driven by the feed drive coil (6) to drive the main shaft (2) through a positioning device to perform feed motion relative to the sleeve (1). The controllable rotary feed system is a precisely controllable rotary and direct drive device capable of separately rotating and feeding and simultaneously rotating and feeding, and can be applied to the fields such as grinding.

Description

technical field [0001] The invention relates to driver technology, in particular to a controllable rotary feed system and a control method, especially a precision controllable rotary and direct drive device. Background technique [0002] The existing tightening device is similar to the structure of a rotary motor, generally only includes a rotary drive, and has a single function. The invention proposes a new type of controllable rotation and direct motion drive device, which can realize both rotation drive and linear feed drive. [0003] Do not find description or report similar to the present invention at present, also do not collect similar data both at home and abroad. Contents of the invention [0004] Aiming at the defects in the prior art, the object of the present invention is to provide a controllable rotary feeding system. [0005] A controllable rotary feed system provided according to the present invention includes: a sleeve 1, a main shaft 2, a rotary drive m...
