Dimension adjustment mechanism of a combined equatorial mount

Abstract

The invention discloses a latitude adjusting mechanism of a combined type equatorial telescope. The latitude adjusting mechanism comprises a base, an hour angle mechanism and a deflection angle mechanism, wherein the hour angle mechanism is connected with the base and can be driven by the latitude adjusting mechanism to rotate around a latitude shaft; the hour angle mechanism is detachably connected with the deflection angle mechanism; the latitude adjusting mechanism comprises two brackets which are fixedly arranged on the base at interval, a connection base which is clamped between the brackets and is connected with the brackets through a rotary shaft, and a screw rod mechanism; the hour angle mechanism is fixedly arranged above the connection base; and the connection base can do rotary movement under the driving of the screw rod mechanism. By adjusting the screw rod mechanism, the connection base can be driven to rotate around the rotary shaft, so that the adjustment of latitude is realized. The latitude adjusting mechanism of the combined type equatorial telescope has the advantages of simple structure, convenience for operation and relatively low manufacturing cost.

Description

technical field [0001] The invention relates to an equatorial mount, in particular to a latitude adjustment mechanism for a combined 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. The existing equatorial mount bracket generally mainly includes a support, an hour angle assembly, etc., wherein the hour angle assembly is installed on the support, and a latitude a...

Problems solved by technology

[0003] However, the current common manual latitude adjustment mechanism has a complex structure and is inconvenient to operate. In the case of heavy load, the adjustment is laborious and not smooth, and even some manual latitude adjustment mechanisms still have relatively large gaps, resulting in the failure of the hour angle components. Precise fixation further leads to inaccurate polar axis adjustment during astronomical observation and the accuracy of image measurement; and the current common automatic latitude adjustment mechanism is relatively expensive to manufacture
