Separate adjustable U-shaped arm for gyro stabilization high definition camera system and assembly method thereof

Abstract

The invention provides a separate adjustable U-shaped arm for a gyro stabilization high definition camera system and an assembly method thereof. The U-shaped arm comprises a left fork arm, a middle shell and a right fork arm, which are separately manufactured, the left fork arm and the right fork arm are separately connected with the middle shell by screws, and the left fork arm and the right fork arm are located and fixed with the middle shell by pins. The assembly method of the U-shaped arm comprises the following steps: 1) separately connecting the left fork arm and the right fork arm with the middle shell by screws; 2) mounting the left fork arm and the right fork arm on both ends of a pitch shaft system structure; 3) debugging the tightness of the screws for connecting the left fork arm and the right fork arm with the middle shell to make a pitch shaft system to rotate on the left fork arm and the right fork arm with a bearing; and 4) fixing relative positions of the left fork arm and the right fork arm and the middle shell by pins after the debugging. By adopting the assembly method provided by the invention, the processing difficulty and cost of the U-shaped arm is reduced, and the distance between the U-shaped arms, the coaxiality of axle holes and the degree of parallelism can be adjusted, so that the functional precision of a gyro stabilization system is improved.

Description

technical field [0001] The invention belongs to the technical field of gyro-stabilized high-definition photography systems, and relates to a separate adjustable U-shaped arm and an assembly method thereof, in particular to a separate adjustable U-shaped arm of a gyro-stabilized high-definition photography system and an assembly method thereof. Background technique [0002] The gyro-stabilized high-definition photography system consists of three parts: the optical system, the gyro-stabilized system and the control system. The existing gyro-stabilized systems mostly use an integrated U-shaped wishbone in the support frame, and the integrated U-shaped wishbone is obtained by machining or casting. wishbone. For the method of machining to obtain the one-piece U-shaped yoke, the machining center is often used for machining and forming. After the dimensional tolerance and shape tolerance are qualified, the whole machine can be assembled. For the method of casting to obtain the one...

Problems solved by technology

[0003] The existing one-piece U-shaped yoke will have problems such as high processing cost, easy deformation after processing, and high scrap rate in actual production and processing, which is not conducive to reducing production costs, and will reduce the coaxial accuracy of the shaft system, resulting in gyro stability Reduced accuracy of system functions

[0004] The existing one-piece U-shaped yoke also has the following disadvantages: 1. It is not easy to process and has high requirements for processing equipment; 2. It needs to be clamped multiple times during machining, and the positioning reference surface is frequently replaced, resulting in high Processing error; 3. In order to improve machining accuracy and reduce part deformation, it is necessary to cooperate with design tooling and fixtures to arrange complex and cumbersome technological processes, which not only prolongs the processing cycle, but also increases production costs; 4. If open mold casting blanks are used, In the method of machining the blank, it will face higher mold opening costs, and the blank needs to be processed again; 5. Contains a cantilever structure, improper heat treatment, easy to deform, resulting in low yield; 6. The distance between the fork arms is not good Adjustment, if the design is updated, the mold needs to be re-cast, and the product interchangeability is poor
