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 described again, the difference is:

[0044] Such as figure 1 and 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 theoretica...

Embodiment 3

[0051] Such as figure 2 and 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 measur...

Abstract

The invention relates to a precision installation and adjustment method for ton-level optical-mechanical components, which belongs to the technical field of ton-level optical-mechanical precision installation. After the optical-mechanical components enter the installation station, coordinate measuring equipment is used to test the external targets of the optical-mechanical components to obtain optical components. The actual measured position of the mechanical component, the target position of the optical mechanical component is obtained by fitting the measured position and the theoretical position, the adjustment amount is calculated, and the adjustment amount is converted into at least 6 independent quantities according to the six-degree-of-freedom positioning principle of the object, and the at least 6 The three independent quantities include the Z-direction adjustment quantity, the X-direction adjustment quantity and the Y-direction adjustment quantity, which are adjusted according to the converted independent quantities. The present invention realizes the precise positioning of the optical-mechanical components, which not only improves the adjustment efficiency, but also ensures the positioning accuracy. , and at the same time, it can satisfy the positioning problem of the optomechanical components supported by various structural types of supporting devices, and has a wide range of applications.

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...
