Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical rotary tables, and particularly to a synchronous rotary table for optical equipment. BACKGROUND

[0002] An optical rotary table is a core component of precise optical equipment, and its main functions include precise control of angles and positions, and improvement of measurement accuracy and efficiency. In general, the equipment assembled on the rotary table has a certain weight, and the traditional optical rotary table needs to be operated in steps when adjusting the Y-axis rotation and the X / Z-axis inclination, which is inconvenient to use. If a synchronous direct driving mode is used to drive the rotary table to rotate and swing in space, the rotary table will be unstable due to the large weight of the assembled equipment, which will cause deviations in experimental or research results, and there is room for improvement. CONTENT OF THE UTILITY MODEL

[0003] In order to enable the traditional optical rotary table to stably adjust the angles of rotation and swinging in different axial directions synchronously, the present application provides a synchronous rotary table for optical equipment.

[0004] The synchronous rotary table for optical equipment provided by the present application adopts the following technical scheme:

[0006] By using the above technical scheme, the driving source in transmission cooperation with the gear transmission assembly on the rack is used to drive the gear transmission assembly to rotate, thereby driving the transmission linkage mechanism arranged between the gear transmission assembly and the swinging frame, so as to achieve the effect of driving the swinging frame to swing. At the same time, the gear transmission assembly synchronously drives the rotary table to rotate, so that when the driving source drives the gear transmission assembly to operate, the effect of swinging the swinging frame and rotating the rotary table synchronously can be achieved. At the same time, since the transmission linkage mechanism is used to drive the swinging frame to swing, the actual stress point of the swinging frame is shifted to the rotary connection between the swinging frame and the rack, rather than the driving part of the swinging frame, thereby reducing the impact of the rotary table on the driving part of the swinging frame when assembling heavy equipment, improving the stability of the swinging of the swinging frame, and finally enabling the traditional optical rotary table to stably adjust the angles of rotation and swinging in different axial directions synchronously.

[0007] Preferably, the gear transmission assembly comprises a first transmission unit, the first transmission unit comprises a first gear, a first rotating shaft and a second gear, two ends of the first rotating shaft are rotatably connected to the rack, and the second gear is coaxially fixed on the first rotating shaft; the first gear is coaxially fixed on the output shaft of the driving source and is in mesh with the second gear, the first rotating shaft is in transmission relationship with the transmission linkage mechanism, and the first transmission unit further comprises a third gear rotatably connected to the rack and in mesh with the second gear, and the third gear synchronously drives the rotating table to rotate.

[0015] Preferably, the two ends of the first rotating shaft are respectively connected to the rotating shaft of the bracket by using a thrust ball bearing and a self-aligning ball bearing.

[0016] By adopting the above technical scheme, the first rotating shaft is preliminarily positioned on one side of the bracket by using the axial positioning function of the thrust ball bearing, and the other end of the first rotating shaft is positioned on the other side of the bracket by using the self-aligning ball bearing, which has the self-aligning function and allows a certain deflection during use.
