Abstract
The utility model belongs to be used to the external location finding technique of the equipment of leading, specifically disclose a prism mounting structure, including base, prism, cushion piece and clamp plate, the prism locate the base in, be equipped with the cushion piece on the prism, pressing plate compresses tightly the cushion piece on the cushion piece for the compression of cushion piece, the clamp plate compresses tightly the prism inside the base through the compression of cushion piece. Two mutually perpendicular's on the prism faceted pebble and two mutually perpendicular's of base faceted pebble contact, the reliable location of guaranteeing the prism. Form a subassembly module after four parts compress tightly, the back of base is a plane, can be convenient install in the plane of other equipment department, base, prism, cushion piece, clamp plate have formed a prism integral erection module, and installation that can be convenient is to other planes, and whole the dismantlement. Satisfied the accurate quick installation of prism, dismantled, reduced the requirement of the processing degree of difficulty by a wide margin.
Description
Technical field
This utility model belongs to the external location technology of inertial navigation equipment, and in particular to a kind of prism mounting structure.
Background technology
Prism is conventional benchmark of the inertial navigation equipment to outside fix, by the reflected in parallel for externally penetrating light, can be used to
Lead the attitude angle of equipment.The installation method of conventional prism is the mounting surface that prism is directly processed on inertial navigation equipment housing, plus
Work difficulty is big, and the installing/dismounting of prism is complicated.Therefore need to design a kind of being applied to without the prism installation of inertial navigation equipment
The mounting structure of requirement.
The content of the invention
The purpose of this utility model is to provide a kind of prism mounting structure, and the accurate Fast Installation that can realize prism is torn open
Unload, while reducing prism mounting surface difficulty of processing.
The technical solution of the utility model is as follows：
A kind of prism mounting structure, including base, prism, cushion film and pressing plate, described prism is located in base, prism
Cushion film is provided with, platen cover compresses cushion film on cushion film so that cushion film compresses, the compression that pressing plate passes through cushion film
Prism is pressed on into chassis interior.
In a kind of above-mentioned prism mounting structure, described base back surface is plane, and prism installation is machined with base
Groove, groove is prismatic, is machined with three sides and former and later two bottom surfaces, prism mounting groove side and prism mounting groove plane perpendicular.
In a kind of above-mentioned prism mounting structure, the shape of prism is consistent with above-mentioned prism mounting groove safety, and prism has
Three sides and two bottom surfaces, prism side is vertical with prism bases.
In a kind of above-mentioned prism mounting structure, described prism side is close to prism mounting groove side, prism bases
It is close to prism and groove bottom is installed.
The beneficial effects of the utility model are as follows：
Two orthogonal faceted pebbles of prism are contacted with the two of base orthogonal faceted pebbles, it is ensured that the reliability of prism is determined
Position.Four parts form an assembly module after compressing, the back side of base is a plane, in that context it may be convenient to set installed in other
At standby plane；Base, prism, cushion film, pressing plate define a prism integral installation module, in that context it may be convenient to be installed to it
In his plane, and integral demounting.The accurate Fast Installation of prism, dismounting are met, the requirement of difficulty of processing is greatly reduced.

Specific embodiment
Below by the drawings and the specific embodiments, the invention will be further described.
As depicted in figs. 1 and 2, prism mounting structure includes base 1, prism 2, cushion film 3 and pressing plate 4.Prism 2 is arranged on
In base 1, cushion film 3 is installed on prism 2, pressing plate 4 is covered on cushion film 3, compresses cushion film 3 so that cushion film 3 compresses,
Pressing plate 4 is pressed on prism 2 inside base 1 by the compression of cushion film 3.
Base 1, prism 2, cushion film 3 and pressing plate 4 form an assembly module after compressing.
As shown in figure 3, the back side of base 1 is a plane, in that context it may be convenient at the plane of other equipment.Base
Prism mounting groove is machined with 1, groove is prismatic, is machined with 2 sides 7 and former and later two bottom surfaces 8, prism mounting groove side 7 with
It is vertical that prism installs groove bottom 8.
As shown in figure 4, the shape of prism 2 is consistent with above-mentioned prism mounting groove safety, prism 2 has three sides 5 and two
Bottom surface 6, prism side 5 and prism bases 6 it is vertical；During installation, prism side 5 is close to prism mounting groove side 7, prism bases 6
It is close to prism and groove bottom 8 is installed, it is ensured that the reliable location in base 1 of prism 2.
As shown in figure 5, the shape of cushion film 3 is consistent with the contact surface shape of prism 2.
As shown in fig. 6, the body shape of pressing plate 4 is consistent with the shape of cushion film 3, two ends are machined with respectively installation portion, install
Screw hole is processed in portion, for pressing plate 4 to be arranged on cushion film 3.
