Embodiment 1

[0040] figure 1 It is a three-dimensional disassembly view of Embodiment 1 of the present invention, figure 2 It is a sectional view of Embodiment 1 of the present invention. In the figure, the meanings of each reference mark are as follows: 1. Working disk surface; 2. Turntable shell; 3. Permanent magnet; 4. Turntable bottom shell; 5. Main shaft; 6. Iron core; 7. Winding coil; 8. Phase Magnetic sensor; 9. Zero position sensor; 10. Zero position trigger permanent magnet; 11. Rotation angle sensor; 12. Bearing.

[0041] An electric turntable, comprising a main shaft 5, on which an iron core 6 is fixedly installed, on which a winding coil 7 is arranged, on the main shaft 5, a working disk surface 1 and a turntable bottom shell 4 are also rotatably installed, and the working disk surface 1 and the turntable The casings are connected in a relatively fixed manner in the circumferential direction, the first permanent magnet 3 is fixedly installed on the turntable casing, and the ...

Embodiment 2

[0060] image 3 It is a partial sectional view of Embodiment 2 of the present invention. In the figure, the same reference numerals as those used in the above-mentioned embodiments still use the definition of the reference numerals in the above-mentioned embodiments, and the meanings of the newly appearing reference numerals in the figure are as follows: 101, turntable body; 102, Adapter.

[0061] The difference between this embodiment and the above-mentioned embodiment is:

[0062] Preferably, the working surface includes a turntable body 101 and an adapter body 102, the adapter body 102 is connected to the turntable housing 2 in a relatively fixed manner in the circumferential direction, the adapter body is rotatably mounted on the main shaft 5, and the turntable body and the adapter body pass through the method LAN connection.

[0063] By dividing the surface of the working table into a turntable body and an adapter body, it is convenient to replace the turntable body se...

Embodiment 3

[0065] Figure 4 It is a partial sectional view of Embodiment 3 of the present invention. In the figure, the same reference numerals as those used in the above-mentioned embodiments still follow the definition of the reference numerals in the above-mentioned embodiments.

[0066] The difference between this embodiment and Embodiment 2 lies in: further preferably, the adapter body 102 and the turntable housing 2 are integrally formed.

[0067] By forming the adapter body 102 integrally with the turntable housing 2, more secure fixing of the turntable body can be achieved.

Abstract

The invention relates to an electric rotary disc. The electric rotary disc comprises a spindle. An iron core is fixedly installed on the spindle. A winding coil is arranged on the iron core. The spindle is further rotationally provided with a working disc face and a rotary disc bottom case. The working disc face and a rotary disc outer case are fixedly connected relative to the circumferential direction. A first permanent magnet is fixedly installed on the rotary disc outer case, and the spindle stretches out of the rotary disc bottom case from the side away from the working disc face. According to the electric rotary disc, an intermediate link of transmission is eliminated, and the rotation precision of the rotary disc is conveniently improved.

Description

technical field [0001] The invention belongs to the technical field of equipment for ceramic molding, hard and brittle material processing and general mechanical processing, and in particular relates to an electric turntable and a method for controlling its rotation angle. Background technique [0002] It is often used for bearing in the fields of ceramic forming (blank drawing, rolling, centrifugal grouting, etc.), hard and brittle material grinding, general product spraying, product machine vision measurement, product photography, product 3D scanning, product display and other fields. And rotate the carousel of the product. The working speed of the turntable is generally from 0 to 400rpm. In the prior art, a motor with a rated speed of not less than 1000rpm is usually used to drive the turntable to rotate after being decelerated by belts, gears, friction wheels or other transmission mechanisms, so it includes 3 parts: motor, transmission mechanism, Working disc and its be...
