Summary of the invention
It is an object of the invention to provide a kind of optical rotary joint, electric rotary connector axiality be prone to ensure photoelectric composite-rotation connector.
In order to solve the problems referred to above, the technical scheme is that
Photoelectric composite-rotation connector, including optical rotary joint and electric rotary connector, the electric rotary connector rotor of electric rotary connector includes the rotary shaft that axis extends along the longitudinal direction, optical rotary joint includes that coaxial line rotates the optical rotary joint stator and optical rotary joint rotor being assembled together, the cable hole arranged with rotating shaft coaxle line it is provided with in rotary shaft, optical rotary joint rotor have coincide fixing be assemblied in described cable hole in so that the coaxial load segment that arranges with rotating shaft coaxle line of optical rotary joint rotor, optical rotary joint stator is fixing with the electric rotary connector stator of electric rotary connector to be connected.
Optical rotary joint rotor is fixed by the steady pin that axis bearing of trend is vertical with fore-and-aft direction and is assemblied in rotary shaft.
Electric rotary connector stator includes stator case and is arranged at the end cap of stator case front end, coaxial load segment is positioned at the front end of optical rotary joint rotor, described coaxial load segment is sleeve-like structure, the rear end coaxial line of described optical rotary joint stator rotates in the endoporus being assemblied in coaxial load segment, and the front end of described optical rotary joint stator is fixedly connected on described end cap.
Offering installing hole on described end cap, the front end of described optical rotary joint stator is plugged in described installing hole, and the front end of optical rotary joint stator is fixed by key, keyway arrangements and installing hole and is connected.
Offer, on the outer peripheral face of described coaxial load segment, the trough extended along the longitudinal direction.
The invention have the benefit that the optical rotary joint rotor in the present invention realizes the axiality requirement of optical rotary joint rotor and electric rotary connector rotor by coaxial load segment and the shaft hole matching of cable hole, and electric rotary connector stator and electric rotary connector rotor are that coaxial line is rotatably assorted, optical rotary joint stator and optical rotary joint rotor are that coaxial line is rotatably assorted, therefore optical rotary joint is ensured that, the axiality requirement of electric rotary connector, the axiality of shaft hole matching is easier to realize, therefore optical rotary joint, the axiality of electric rotary connector is prone to ensure, whole photoelectric composite-rotation connector product is prone to make.
Further, the rear end coaxial line of optical rotary joint stator rotates in the endoporus being assemblied in coaxial load segment, that is the biggest coaxial load segment and cable hole shaft hole matching, the most whole optical rotary joint rotor can load in cable hole completely, and the rear end of optical rotary joint stator also can be because being positioned in cable hole in stretching into coaxial load segment, the front end of the most whole optical rotary joint only optical rotary joint stator is positioned at outside rotary shaft, so greatly reduces the axial dimension of photoelectric composite-rotation connector.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the present of invention.
Detailed description of the invention
nullThe embodiment of photoelectric composite-rotation connector is as shown in Figure 1: include optical rotary joint and electric rotary connector，Optical rotary joint includes that coaxial line rotates the optical rotary joint stator 10 and optical rotary joint rotor 1 being assembled together，Optical rotary joint stator 10、Arrange before and after optical rotary joint rotor 1，Electric rotary connector includes electric rotary connector stator and the electric rotary connector rotor that coaxial line is assembled together，Electric rotary connector stator includes stator case 4 and is arranged at the end cap 8 of stator case 4 front end，Electric rotary connector rotor includes the rotary shaft 11 that axis extends along the longitudinal direction，Axially spaced in rotary shaft it is provided with multiple conducting ring 2，The conduction brush 3 coordinated with conducting ring conductive contact it is provided with on electric rotary connector stator，The cable hole 12 arranged with rotating shaft coaxle line it is provided with in rotary shaft.nullThe front end of optical rotary joint rotor have coincide be assemblied in cable hole 12 in so that the coaxial load segment 7 that is coaxially set of optical rotary joint rotor 1 and rotary shaft 11，Coaxial load segment 7 is fully located in cable hole 12，Offer, on the outer peripheral face of coaxial load segment 7, the trough 5 extended along the longitudinal direction，Optical rotary joint rotor is fixed by the steady pin 6 that axis bearing of trend is vertical with fore-and-aft direction and is assemblied in rotary shaft 11，Coaxial load segment is sleeve-like structure，The rear end of rotary connector stator 10 is rotated by coaxial bearing line in the endoporus being assemblied in coaxial load segment，Steady pin is then between two bearings，The front end of optical rotary joint stator is fixedly connected on end cap 8，Installing hole is offered on end cap，The front end of optical rotary joint stator is plugged in installing hole，Key is passed through in the front end of optical rotary joint stator、Keyway arrangements 9 is fixing with installing hole to be connected，Key、Keyway arrangements includes the keyway being arranged on optical rotary joint stator and end cap and the key being plugged in keyway.
Coaxial load segment and cable hole shaft hole matching realize the axiality matching requirements of optical rotary joint rotor and electric rotary connector rotor, axiality is prone to ensure, after ensuring coaxiality between both of which, optical rotary joint stator, the axiality of electric rotary connector stator are the most just guaranteed, and substantially increase stability and the reliability of product；The coaxial load segment being relatively large in diameter contacts cooperation with cable hole, the least optical rotary joint stator is then plugged in the endoporus of coaxial load segment, it is achieved in that optical rotary joint rotor can load in cable hole completely, the most most optical rotary joint stator also can be the most overlapping with cable hole, is thus greatly reduced the axial dimension of product.
In other embodiments of the invention: between optical rotary joint rotor with electric rotary connector rotor, can also pass through that other fixed structures such as key, keyway arrangements, bolt structure are fixing to be connected；Can also be connected by other fixed structure such as pin, screw is fixing between optical rotary joint stator with electric rotary connector stator；Coaxial load segment can also be positioned at the front end of optical rotary joint rotor, and now optical rotary joint stator can rotate and be plugged on optical rotary joint rotor and can also be loaded on optical rotary joint rotor by turning set；When coaxial load segment does not affect the conductor wiring being connected with conducting ring, the trough on coaxial load segment can not also set.
