Axial clearance is eliminated by adjusting shims, and radial clearance is eliminated by using back-to-back mounting of angular contact bearings. Combined with the high speed of the brushless motor and the trigger signal from the photoelectric sensor, the uniformity and continuity of the speed and stroboscopic control signal are achieved.
It achieves uniformity and continuity of signal control at high speeds of brushless motors, meets the high-speed requirements of high-speed rotating mechanisms, and simplifies the debugging process.

Abstract
Description
Technical Field
[0001] This utility model relates to the fields of industrial testing or military technology, specifically a strobe-synchronous high-speed rotating mechanism. Background Technology
[0002] The existing rotating mechanism achieves speed measurement and calibration by setting marking points on the rotor and using an external stroboscope to emit adjustable and synchronized flashes of light, ultimately creating the illusion of stillness to the operator. While the stroboscope measures speed non-contactly, this method requires visible marking points to be affixed to the rotating mechanism and for the light to penetrate the observation window of the hatch and illuminate the rotor markings. A small, dirty, dark-coated, or poorly light-transmitting observation window can negatively impact the flashing effect and clarity of observation. Utility Model Content

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] For examples, please refer to Figures 1-5 This utility model provides a technical solution:
[0024] A strobe-synchronous high-speed rotating mechanism includes a spindle assembly 1, a brushless motor 2, a coupling 3, an adapter disc 4, a housing 5, a motor mounting end cover 6, a cooling fan 7, a rotating shaft 8, a first angular contact bearing 9, a spindle housing 10, an encoder A11, an encoder B12, a photoelectric sensor 13, a second angular contact bearing 14, a spindle end cover 15, a bushing 16, a screw ring 17, a sensor mounting base 18, and several screws. The encoder A11 and encoder B12 are connected to the bushing 16 by screws to form a bushing assembly. The first angular contact bearing 9 is mounted on the surface of the spindle housing 10. The cooling fan 7 is mounted on the surface of the housing 5. The rotating shaft 8 passes through the first angular contact bearing 9, and the bushing assembly passes through the other end of the rotating shaft 8. The spindle end cover 15 passes through the surface of the rotating shaft 8 and is fixed to the surface of the spindle housing 10 by screws.
[0025] In this embodiment, as Figure 1 and Figure 2 As shown, the second angular contact bearing 14 passes through the rotating shaft 8 and is mounted on the spindle end cover 15, and is locked with a screw ring 17. The photoelectric sensor 13 is fixed to the surface of the sensor mounting base 18 with screws. The sensor mounting base 18 is mounted on the surface of the spindle housing 10 to form the spindle assembly 1. The brushless motor 2 is rotatably connected to the spindle assembly 1 through the coupling 3. The spindle assembly 1 is fixed to the surface of the adapter plate 4 with screws. The housing 5 is fixed to the surface of the adapter plate 4 with screws. The brushless motor 2 is mounted on the surface of the motor mounting end cover 6.
[0026] Specifically, the axial clearance of the spindle assembly 1 is eliminated by adjusting the shims, and the radial clearance is eliminated by the back-to-back mounting of the angular contact bearings. At the same time, the rotation triggers a speed control signal and a strobe control signal. The speed control signal is uniform and continuous, and the strobe control signal is unique.
[0027] In this embodiment, as Figure 3 and Figure 4 As shown, coupling 3 is fitted onto shaft 8 and secured to the surface of D-shaped shaft with lateral screws. Motor shaft 8 is inserted into the other side hole of coupling 3. Motor mounting end cover 6 is fixed to housing 5 with screws. Lateral screws on the surface of coupling 3 are used for fastening. The first angular contact bearing 9 and the second angular contact bearing 14 are of the same model and made of the same material. Code disks A11 and B12 are both circular in shape and made of stainless steel.
[0028] The power unit consists of a brushless motor 2 and a matching driver. The brushless motor 2 has an adapter shaft. The power unit has a speed of up to 10,000 Rpm, which can meet the high speed requirements of the rotating mechanism. At the same time, the matching driver makes the debugging process simple.
[0029] The working process of this utility model is as follows: When the strobe synchronous high-speed rotating mechanism designed in this scheme is working, the DC power supply powers the main control board, driver, photoelectric sensor 13, cooling fan 7, etc. The main control board sends a rotation command to the driver, and then the driver drives the motor to rotate at the set speed. During the rotation, the encoder A11 and encoder B12 trigger speed control signals and strobe control signals. The speed control signal is directly input to the main control board for speed stabilization control, and the strobe control signal is input to the strobe switch circuit to control the strobe light to flash. The strobe control signal has only one signal for one rotation, so it can maintain the same frequency as the rotation speed. The cooling fan 7 rotates continuously after the power supply is turned on, continuously cooling the entire system.
[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
