The Method of Using Linear CCD to Realize the Detection and Adjustment of Mechanical Zero Position

Abstract

The invention discloses a method for realizing mechanical zero position detection and adjustment by using a linear ccd. The adopted device includes a marble platform, a servo motor, a reducer, a deceleration support, a rotating main shaft, a brake, a brake support, an encoding disc, a bottom plate, and a gantry Frame, parallel light source, linear ccd and tooling to be tested; the present invention has designed linear ccd to carry out the detection of mechanical zero position, does not need to carry out the step of carrying out levelness detection to the marble platform used for processing additionally before detection, can pass mechanical assembly To ensure that the illumination direction of the monochromatic light emitted by the parallel light source is parallel to the marble platform, there is no need to install testing mechanisms such as level gauges, and there is no need to design platform leveling mechanisms, which greatly saves the design cost of the overall device and also avoids traditional mechanical design. In the method, because of the deviation between the processing platform and the absolute horizontal position, the zeroing result of the whole mechanism is disturbed.

Description

technical field [0001] The invention relates to the field of aerospace and aviation, and more specifically relates to a method for realizing mechanical zero position detection and adjustment by using a linear ccd. Background technique [0002] There is a zero adjustment mechanism, which is used to adjust the zero position of a rotatable mechanism. The adjusted mechanism is used to drive the subsequent device to rotate, so it is necessary to ensure that the deviation between the mechanical zero position and the electrical zero position is within a certain range of accuracy. So it needs to be zeroed. There are two positioning pin holes on the mechanism to be zeroed, and the horizontal position of these two pins is taken as the mechanical zero position, and these two positioning pin holes need to be adjusted to make them completely horizontal. The device has a servo motor and a reducer, which can drive the rotation of the tooling to be zeroed. It is designed with an encoding d...
