Embodiment Construction

[0037] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] The invention provides a combined positioning pin device and its installation method, which solves the problem of difficult readjustment and positioning of equipment or loads after being disassembled many times during the development process, and avoids the process of matching pins on the machine tool after the equipment is assembled, reducing the Reduced risks and shortened the development cycle. The relative positions of the two components are constrained and positioned by two sets of devices, and after positioning, the whole component is a rigid unit. In addition, all the parts of the combined positioning pin device of the present invention are processed before assembly of components, the positioning accuracy is micron level, and it can be produced in batches.

[0039] Such as figure 1 As shown, ...

Abstract

The invention provides a combined positioning pin device and a mounting method thereof, and solves the problem of difficult readjustment and positioning of equipment or loads after multiple times of disassembly. The device comprises a first pin, a second pin, a flexible connecting piece, a locking nut and a skin, wherein the flexible connecting piece comprises a first pin sleeve, a flexible sleeveand a second pin sleeve connected in sequence; the first pin comprises a first connecting section, a first limiting section and a second connecting section arranged in sequence; the first connectingsection is arranged in the first pin sleeve and a second avoiding hole; the first limiting section is arranged in the second avoiding hole; the second connecting section is arranged in a first positioning hole; the second pin comprises a third connecting section, a fourth connecting section, a second limiting section and a fifth connecting section arranged in sequence; the fourth connecting section is arranged in the second pin sleeve; the second limiting section is arranged on the outer side of the second connecting piece; the fifth connecting section is arranged in the first avoiding hole and a second positioning hole; the locking nut sleeves the third connecting section; and the skin coats the outer side of the flexible sleeve.

Description

technical field [0001] The invention relates to a locating pin, in particular to a combined locating pin device and an installation method thereof which allow readjustment and positioning after multiple disassembly. Background technique [0002] With the continuous development of aerospace technology, the accuracy index parameters of optical remote sensing payloads carried by satellites are getting higher and higher, such as hyperspectral imagers and high-resolution cameras. Such optical remote sensing loads generally include detector components, front telescopic system components, lens components, interferometer components, prism components, grating components, large box parts and hood parts. These components or parts are installed according to optical measurement means. Adjust in place, after the screws are tightened, each part needs to use a boring machine or a drilling machine to punch pin holes between components, between parts or between components and parts, and perfo...
