Detailed Implementation

[0020] To make the objectives, technical solutions, and technical effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown in the embodiment of the present invention, a small precision rotary lifting platform based on grooved wheel drive and servo brake is provided, including lifting module 1, rotating module 2 and braking module 3. The lifting module 1 controls its upper plate 103 to move up and down along the optical axis 101 to realize lifting operation. The lifting module 1 is installed on the rotating module 2 and is controlled to rotate by the rotating module 2, rotating together with it. The braking module 3 is installed below the rotating module 2 and performs braking control on the rotating module 2.

[0022] like Figures 2-4As shown, the rotating module 2 includes: an upper rotating disk 110, a lower rotating disk 205, a cross bearing 206, a Geneva mechanism 204, a lower plate 201, a worm gear reducer motor 202, and a motor connector 203; wherein, the upper rotating disk 110 and the lower rotating disk 205 are fixedly connected by bolts; the lower rotating disk 205 is annular, and has several evenly distributed embedded straight slots 207 on its inner circumference. The Geneva mechanism 204 is fitted at one of its straight slots 207, and the active rotation of the Geneva mechanism 204 drives the passive rotation of the lower rotating disk 205; since the lower rotating disk 205 is annular, its middle... It is hollow, so the upper rotating disk 110 and the lower plate 201 can be connected by the cross bearing 206; the lower plate 201 has two square through holes corresponding to the position of the straight slot 207 and a circular through hole corresponding to the position of the Geneva mechanism 204. The size of the two square through holes can be set according to specific needs; the worm gear reducer motor 202 is located at the circular through hole and is installed on the lower surface of the lower plate 201 by the motor connector 203. The worm gear reducer motor 202 is driven by the Geneva mechanism 204 through the through hole. Specifically, the output shaft of the worm gear reducer motor 202 is driven by the cylindrical pin of the Geneva mechanism 204.

[0023] When the rotating module 2 of the present invention is rotating, the worm gear reducer motor 202 drives the Geneva mechanism 204 to rotate. At the same time, based on the provided cross bearing 206, the Geneva mechanism 204 uses its active dial to intermittently engage with the straight slot 207 when rotating, which drives the lower rotating disk 205 to rotate. Since the upper rotating disk 110 and the lower rotating disk 205 are fixedly connected by bolts, the upper rotating disk 110 also rotates synchronously.

[0024] like Figure 5 As shown, the lifting module 1 includes: optical shaft 101, circular flange linear bearing 102, upper plate 103, hinge 104, spring 105, linkage mechanism 106, first servo motor fixing component 107, lifting servo motor 108, and coupling 109. The optical shaft 101 is located in the middle of the upper rotating disk 110 and is connected to the upper rotating disk 110 through the coupling 109. The upper plate 103 is sleeved on the optical shaft 101 through a circular flange linear bearing 102. The lifting servo motor 108 is fixedly installed on the upper rotating disk 110 using a first servo motor fixing part 107. The drive shaft of the lifting servo motor 108 is connected to one end of the linkage mechanism 106, and the other end of the linkage mechanism 106 is connected to the lower surface of the upper plate 103 through a hinge 104. The spring 105 is sleeved on the lower part of the optical shaft 101, and its lower end abuts against the coupling 109, which can effectively assist the upper plate 103 in rising from a low position.

[0025] In this embodiment, three lifting servos 108 fixed on the upper rotating disk 110 provide power. The lifting servos 108 drive the linkage mechanism 106 to realize the rapid and precise linear lifting of the upper plate 103 along the optical axis 101.

[0026] like Figure 6 and Figure 7 As shown, the brake module 3 includes: a Hall sensor 301, a brake servo motor 303, a single-arm servo disc 304, and a second servo motor mounting member 302; wherein, the Hall sensor 301 is located at one of the square through holes of the lower plate 201 and is fixedly installed on the lower surface of the lower plate 201; the brake servo motor 303 is located on one side of the other square through hole of the lower plate 201 and is fixedly installed on the lower surface of the lower plate 201 by the second servo motor mounting member 302; the single-arm servo disc 304 is disposed at the other square through hole and is drivenly connected to the brake servo motor 303.

[0027] This invention utilizes a Hall sensor 301 to detect the rotation angle of the rotating lifting platform, and employs a brake servo motor 303 to drive a single-arm servo disc 304, thereby achieving rapid and precise braking by locking the straight slot 207 of the lower rotating disc 205.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any way. Although the implementation process of the present invention has been described in detail above, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. All modifications and equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
