Embodiment Construction

[0045] Below in conjunction with accompanying drawing and specific embodiment content of the present invention is described in further detail:

[0046] A method for assembling and adjusting a lifting mechanism with four lead screws in a high straightness within a full stroke, comprising the following steps:

[0047] 1) Preparation before installation

[0048] A. Lead screw preparation

[0049] a1) Check the four lead screws of the lifting mechanism to be installed to ensure that the height difference between the four lead screws is ≤0.03mm, and there are no obvious discontinuities and distortions in the tooth profile of each lead screw;

[0050] Use an altimeter to measure the height between one end face of the lead screw and the other end face. If there is a large height difference between the four lead screws, grind the two end faces of the lead screw to ensure that the height difference of the four lead screws is ≤0.03 mm.

[0051] a2) Use the detection method of the dia...

Abstract

The invention provides an assembling and adjusting method for high-linearity lifting of a mechanism comprising four lead screws in the whole stroke, and solves the technical problem that safety risks exist due to the fact that an existing mechanism comprising the four lead screws does not have a quantitative means for verifying the lifting linearity in the whole stroke. According to the invention, an internal focusing telescope, a framed reticle tool and a half-load product simulation tool are utilized to assist debugging, and high-linearity lifting adjustment of a lifting mechanism containing four lead screws in a whole stroke is completed. High-straightness lifting of the lead screw is a common working mode of photoelectric products of the unmanned aerial vehicle, and on the premise that the product precision is guaranteed, the working efficiency is improved, the assembly cost is reduced, and wide application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of optical adjustment, and in particular relates to an installation and adjustment method for a lifting mechanism including four lead screws to move up and down with high straightness in the whole stroke. Background technique [0002] UAVs usually use a lifting mechanism with four screw screws to lift the product, which requires high straightness; among them, the lifting mechanism includes fixed plates at both ends, four screw screws, side rib plates, lifting discs, motors, Motor driver, chain, Hall device and other components. [0003] At present, most of the straightness of the four lead screws is adjusted by visual dial gauge values, and there is no process quantitative measurement method, which is finally verified in the system. Therefore, there are certain safety risks. For example, if there is a jam during use If the drone is stagnant, the product will stop moving in a straight line, and the product w...
