Problems solved by technology

The first type of structure is simple and low in cost, but the shaft system of the main body of the test equipment is easily affected by high and low temperature, the frame is prone to deformation, and its own accuracy is difficult to guarantee; the second type of structure, the shaft system frame is located outside the thermostat, and the accuracy of the equipment is reliable However, due to the movement of the main body of the thermostat in the space, high requirements are put forward for equipment waterproof, thermal isolation, shaft thermal design, electrical protection, etc.
[0004] The high-precision indexing mechanism has been placed outdoors for a long time, and it is often affected by low temperature in winter in northern my country, which makes it unable to work normally. In order to reduce the impact of the external low temperature environment on its overall temperature, it is necessary to design a temperature control device for it. It is used to control the temperature of key components such as code discs and bearings in the high-precision indexing mechanism within the normal operating temperature range to ensure that they can work normally even when the external ambient temperature is low

Embodiment Construction

[0020] A high-precision indexing mechanism with temperature control function, including a horizontal axis 10 and a vertical axis 11, the horizontal axis 10 drives the worktable 1 to complete the rotation movement in the pitch direction; the vertical axis 11 drives the pitch base 4, and the pitch base 4 drives the worktable 1 Complete the rotational movement in the yaw direction, and make the normal of the worktable 1 point to any area of ​​the sky through the horizontal axis 10 and the vertical axis 11. The whole device is installed on the yaw base 5 .

[0021] The sensor 2 is installed on the outer periphery of the horizontal axis 10. When the outdoor temperature is lower than the allowable working temperature of the sensor 2, the temperature control system 3 is turned on, and the temperature control system 3 respectively controls the first-stage temperature control system 6 on the yaw base 5 and the temperature control system on the yaw base 5. The second-level temperature c...

Abstract

The invention discloses a high-precision indexing mechanism with a temperature control function. The high-precision indexing mechanism comprises a transverse shaft and a vertical shaft, and the transverse shaft drives a workbench to complete rotational motion in the pitching direction; the vertical shaft drives a pitching base, the pitching base drives the workbench to complete rotational motion in the yawing direction, and through the transverse shaft and the vertical shaft, a normal of the workbench points to any area of the sky; the whole mechanism is installed on a yawing base; a sensor isinstalled at the periphery of the transverse shaft. The mechanism further comprises a temperature control system, and the temperature control system controls a first-stage temperature control systemlocated on the yawing base and a second-stage temperature control system located on the pitching base separately.

Description

technical field [0001] The invention belongs to the field of indexing mechanisms, and in particular relates to a high-precision indexing mechanism with a temperature control function. Background technique [0002] The high-precision indexing mechanism is a high-precision special testing equipment, which is mainly used for star sensor field calibration. It is installed in the observation cover on the roof of the observatory. When in use, the dome cover is opened, and the star sensor grating equipment observes the luminous stars in the sky. [0003] According to new searches and industry knowledge, there are two main types of equipment (turntables) that commonly implement temperature control functions: and focus on the simulation of high and low temperature environments. At present, the high and low temperature boxes used in testing equipment are mainly divided into two forms in terms of structure: 1. One is that the thermostat box wraps the main body of the shaft system of th...
