Embodiment approach

[0016] like Figure 1~3 As shown, the present invention is realized by using a measurement reference point device 1 and a measurement positioning device connected to the reference point device 1 . The measuring and positioning device described in this embodiment includes a measuring ball device 2 and a prism positioning device 3 . The measuring ball device 2 includes a measuring ball support and a sphere arranged in sequence. The prism positioning device includes a connected prism holder and a prism.

[0017] The method for the precise positioning of large components of the present invention comprises the following steps:

[0018] Step 1. Install and embed the measurement reference point device 1 on the large component. like figure 1 As shown, the installation position of the measurement reference point device 1 should be convenient for installing the measurement positioning device used later, and it should be convenient for measurement and observation. The structure of t...

Abstract

The invention discloses a method for precisely positioning a large member, which comprises the following steps: 1, arranging and embedding a datum mark device on the large member; 2, machining parts to be machined of the large member; 3, arranging a measuring ball device on the datum mark device, and reading sphere center coordinates of a sphere; 4, during the field installation of the large member, detaching the measuring ball device, arranging a prism positioning device on the datum mark device, and ensuring that the prism central position of the prism positioning device is consistent with the position of a sphere center of the measuring ball device; and 5 using a total station for measurement and precisely positioning the parts to be machined of the large member relative to the positions of other members. The method simply and conveniently realizes the requirements of large membrane on machining and field precise positioning, is suitable to be used when the datum mark device and the member are difficult to machine at the same time, and realizes precise positioning of the parts to be machined during the installation of the large member.

Description

technical field [0001] The invention relates to a method for precise positioning of a large-scale component, in particular to a method for setting a measuring reference point device in the large-scale component so as to accurately position the metal processing part when the large-scale component is installed. Background technique [0002] At present, some large-scale components need to be metal-processed, that is, metal parts are cut on the machine tool, and the processed parts are required to maintain high dimensional and positional accuracy relative to other components during installation. This requires setting several measuring reference point devices on the component. [0003] Due to the special location of the measurement reference point device, it is difficult to process it together with the component, or the function of the machine tool needs to be increased to greatly increase the cost. Therefore, it is necessary to provide a method that is convenient for processing...
