Horizontal counterweight instrument for pole coordinate measurement

Abstract

The invention discloses a horizontal counterweight instrument for pole coordinate measurement, which comprises a flat plate, one end of the flat plate is fixed with a connecting plate, the connecting plate is perpendicular to the flat plate, a driving device is also fixed on the flat plate, and the connection between the driving device and the connecting plate is A guide rail fixed on the surface of the flat plate and a counterweight capable of sliding along the guide rail are provided, and the counterweight is connected to the driving end of the driving device; the surface of the flat plate is also provided with an electronic level and a single-chip microcomputer, and The signal receiving end is connected with the electronic level, and the signal output end is connected with the driving device; the limit switch facing the guide rail is arranged on the connecting plate, and the limit switch is also connected to the signal receiving end of the single-chip microcomputer; the upper part of the connecting plate A dust cover covering the panel is also fixed. The invention is used to solve the problem that the center of gravity of the pole coordinate measuring instrument in the prior art is continuously moved and affects the measurement accuracy, and realizes the purpose of automatically adjusting the center of gravity of the pole coordinate measuring instrument.

Description

technical field [0001] The invention relates to the field of surveying instruments, in particular to a horizontal counterweight instrument for pole coordinate measurement. Background technique [0002] In the fields of large precision equipment such as ships, aviation, and military industry, the measurement of polar coordinates and propeller pitch is very common and necessary. However, in the current process of measuring the polar coordinates of the workpiece and the pitch of the propeller, if the X coordinate, Y coordinate, and angle are measured manually, the workload is huge and errors are prone to occur. Therefore, a polar coordinate measuring machine is usually used for measurement. However, when the currently used polar coordinate measuring device is used, the support arm where the stylus is located is set on one side of the rotating shaft system of the polar coordinate measuring device, and the workpiece to be measured is connected to the measuring instrument through...
