Problems solved by technology

The installation adjustment basically adopts the manual adjustment method, using a crowbar or a hammer to knock. This adjustment method is random, cannot be quantitatively adjusted, and takes a long time
At the same time, the diversification of the structure of the support device of the optomechanical component leads to different and irregular installation and adjustment methods, which increases the difficulty of installation and adjustment

Embodiment 1

[0036] A precision installation and adjustment method for ton-level optical-mechanical components, comprising the following steps:

[0037] S1. After the optical-mechanical component enters the installation station, use the coordinate measuring equipment to test the external target of the optical-mechanical component to obtain the actual measured position of the optical-mechanical component. The measured position is the current position of the optical-mechanical component represented by the coordinate group value of the external target of the test attitude, wherein the coordinate measuring device is preferably a laser tracker.

[0038] S2. Obtain the target position of the optomechanical component by fitting the measured position with the theoretical position, and calculate the adjustment amount. Specifically, the theoretical position is the pose of the optomechanical component represented by the model and drawings. Due to the existence of the error of the optomechanical compon...

Embodiment 2

[0043] The same part of this embodiment and Embodiment 1 will not be repeated, the difference is:

[0044] Such as figure 1 with figure 2As shown, when the supporting device of the optomechanical component is the supporting tool 1, the 6 independent quantities include 3 Z-direction adjustments, 2 X-direction adjustments and 1 Y-direction adjustment, and the supporting tool 1 is set below There are 4 outriggers, select the 3 outriggers that coordinate measuring equipment 2 can see through as the adjustment outriggers, set the target seat 4 on the adjustment outriggers, set the support plate 3 under the adjustment outriggers, and correspond to the adjustment outriggers Offer the fixed block connecting port on the support plate 3.

[0045] Specifically, the coordinate measuring device 2 is used to test the external target of the optomechanical component to obtain the measured position of the optomechanical component. After fitting the measured position and the theoretical posi...

Embodiment 3

[0051] Such as figure 2 with image 3 As shown, when the supporting device of the optomechanical assembly is a support seat, the target seat is set on the support seat. In this embodiment, the optomechanical assembly is in a tilted state. The supporting seat is a conical support 9, a V-shaped support 11 and a plane support 10, and at the same time, a support plate is provided under the conical support 9, the V-shaped support 11 and the plane support 10. The 6 independent quantities include 3 Z-direction adjustments, 2 Y-direction adjustments and 1 X-direction adjustment. To adjust the X-direction of the conical support 9 or V-shaped support 11 or plane support 10, this In the embodiment, the conical support 9 is adjusted in the X direction, the conical support 9 and the V-shaped support 11 are adjusted in the Y direction, and the conical support 9, the V-shaped support 11 and the plane support 10 are adjusted in the Z direction .

[0052] Specifically, the coordinate measu...

Abstract

The invention relates to a precise installing and adjusting method for a ton-level optical machine assembly, and belongs to the technical field of ton-level optical machine precise installation. After the optical machine assembly enters an installation station, a coordinate measuring device is used for testing an external target of the optical machine assembly to obtain an actual measurement position of the optical machine assembly, and a target position of the optical machine assembly is obtained through fitting of the actual measurement position and a theoretical position; and the adjustment amount is calculated, the adjustment amount is converted into at least six independent amounts according to the object six-degree-of-freedom positioning principle, the at least six independent amounts include the Z-direction adjustment amount, the X-direction adjustment amount and the Y-direction adjustment amount, and adjustment is conducted according to the converted independent amounts. With the precise installing and adjusting method for the ton-level optical machine assembly, it is achieved that the optical machine assembly is precisely positioned, the adjustment efficiency is improved while the positioning accuracy is guaranteed, and meanwhile, the problems about positioning of optical machine assemblies supported by supporting devices of various structure types can be solved, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of ton-level optical-mechanical precision installation, and in particular relates to a precision installation and adjustment method for ton-level optical-mechanical components. Background technique [0002] In large-scale laser inertial confinement fusion devices and other large-scale optical projects, there are some opto-mechanical components with large volume and ton weight. Accuracy requirements, the existing processing and manufacturing technology can not meet the above precision requirements. Even if there is a manufacturing process that can meet the precision requirements, the cost required is very expensive. Therefore, its accuracy requirements can only be achieved through installation and adjustment. [0003] At present, high-precision coordinate measurement technology is used in the installation of large optical-mechanical components. After measurement and conversion, the precise adjustment amount...
