Clutch locking device of equatorial instrument

Abstract

The invention discloses a clutch locking device of an equatorial instrument. The clutch locking device comprises a steel ball, an automatic block and a regulating mechanism, wherein the automatic block is respectively in contact with a hour angle worm gear and a hour angle shaft; the regulating mechanism is inserted in a central hole of the hour angle shaft to underprop the steel ball during locking; and the steel ball is used for extruding the automatic block under the action of the underpropping force, thus causing the automatic block to expand and be closely connected with the hour angle worm gear and the hour angle shaft. During the work of the clutch locking device, the regulating mechanism is locked, the regulating mechanism underprops the steel ball, the steel ball extrudes the automatic block under the action of the underpropping force, and the automatic block expands and is closely connected with the hour angle worm gear and the hour angle shaft under the action of the extrusion force, thus realizing close connection of the hour angle shaft and the hour angle worm gear.

Description

technical field [0001] The invention relates to an equatorial mount, in particular to a clutch locking device for an equatorial mount, belonging to the technical fields of astronomy and measurement. Background technique [0002] An equatorial mount is a common instrument for measuring angles. It is usually used in conjunction with astronomical telescopes for astronomical observations, and provides measurement scientific data for astronomical phenomena and astronomical research. Generally speaking, because the equatorial mount must make compound angle adjustments in three-dimensional space, its bracket must have high precision, so that the observation angle of the matching telescope can be accurately adjusted to achieve precise positioning of celestial bodies and real-time track. [0003] The existing equatorial mount generally includes a base, an hour angle mechanism, a deflection mechanism and a clutch locking device. The hour angle mechanism is connected to the base and c...

Problems solved by technology

[0004] However, the existing clutch locking devices usually use tensioning parts to realize the tight connection between the hour-angle worm gear and the hour-angle shaft, and the common tensioning parts are circular structures, and the contact surface between them and the hour-angle worm wheel is a short straight line. As a result, the contact surface is small, which causes the hour angle worm gear and the hour angle shaft to not lock each other tightly, thereby affecting the stability and use of the equatorial mount
