Specific implementation mode
The present invention is described further with reference to the accompanying drawings and examples.
In recent years, popularizing with theories such as automation, intelligence, miniaturizations, Split encoder is by numerous users'
It welcomes, compared with monoblock type encoder, the structure of Split encoder more minimizes, and reduces the production cost, and is improving
On the basis of product reliability, the service life of encoder is extended.
But all there is Split encoder common at present installation complexity, installation environment to require high, installation element precision
It is required that the problems such as high, fragile optical device.
Embodiment one：As shown in Figures 1 to 3, only one of present invention embodiment, a kind of fission of integral type installation
Formula encoder, including body assembly 1 and grating assembly 2, the grating assembly 2 is at least part of to be located at the body assembly 1
It is interior, and the grating assembly 2 is fixed with the body assembly 1 by the pre- cartridge screw 3 that generally radially direction is extended and is connected
It connects, the through-hole 111 that generally radially direction extends is provided in the main body 11 of the body assembly 1, the pre- cartridge screw 3 is at least
Some is located in the through-hole 111, is provided with what generally radially direction extended in the rotary shaft 21 of the grating assembly 2
Threaded hole 211, the pre- cartridge screw 3 is at least part of to be located in the threaded hole 211, and use is additionally provided in the main body 11
In the function that setting is threadedly coupled with the threaded hole 211 in the fixing end 112 of the fixation main body 11, the threaded hole 211
Screw 212.
In a kind of Split encoder of integral type installation of the present invention, the grating assembly 2 is by extending in a radial direction
The pre- cartridge screw 3 being arranged is fixedly connected with the body assembly 1, and the pre- cartridge screw 3 at least there are two since be prepackage spiral shell
Nail 3, be exactly before encoder installation, grating assembly 2 is previously placed in when encoder produce within body assembly 1 and with
Body component 1 is connected, and the pre- cartridge screw 3 is to extend in a radial direction setting, ensures to extend inward from 11 outside of main body, wear
Main body 11 is crossed to be threadedly coupled with the rotary shaft 21 of grating assembly 2.
Certainly, there are one states for a kind of Split encoder of integral type installation of the present invention, after as pre-installing just
Formula is installed, and is at this time removed the pre- cartridge screw 3, function screw 212 is screwed into threaded hole 211, installation can be completed.
User can directly assemble when mounted, without completing complicated placement and alignment operation, greatly reduce installation
Difficulty saves working hour, and grating assembly 2 reaches equilibrium state after the locking of pre- cartridge screw 3, will not be with body assembly 1
The alignment of grating and reading head can be accurately transferred under the installation equipment of user when relative displacement occurs, therefore assembling, and be made
Encoder reaches high-precision and exports.
It is noted herein that the quantity at least two of the through-hole 111.The quantity of the threaded hole 211 is also
At least two groups.When practical operation, the quantity of the pre- cartridge screw 3 is identical as the quantity of the through-hole 111.
That is, the effect of prepackage screw thread 3 is that grating assembly 2 is made to reach equilibrium state after the locking of pre- cartridge screw 3,
Relative displacement will not occur with body assembly 1, so we when formal installation, specific installation steps are to remove one in advance
Cartridge screw 3 installs a function screw 212, then finishes remaining all dismountings of pre- cartridge screw 3, is only and completes encoder
Installation.
Best operational circumstances are to install a function screw 212, then remove a pre- cartridge screw 3, be repeated twice, so
Remaining all dismountings of pre- cartridge screw 3 are finished afterwards, complete the installation of encoder.
That is, the function screw 212 at least one can reach mounting condition, but in order to make the present invention one
The Split encoder installation of kind integral type installation is most stable, and the function screw 212 should install two.
