Description
Technical field
The present invention relates to electricity field more particularly to encoder, especially a kind of integral type bearing-free encoder.
Background technique
No built-in bearing encoder is also known as Split encoder, is a kind of without itself rotation reference, by pedestal, grating group
Part, PCBA component and light source composition;
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 type encoder is more minimized, and is reduced the production cost, and is being improved
On the basis of product reliability, the service life of encoder is extended;But Split encoder common at present all has peace
Dress is complicated, installation environment require it is high, installation element precision require it is high, the problems such as optical component easy to damage.
In the prior art, a kind of Split encoder of integral type installation as disclosed in patent gazette CN108731709A,
Its grating assembly is located within the body, and is connected by screw with ontology, and there are three uniformly distributed radial directions to lead to for band in the radial sidewalls of ontology
There is the threaded hole for screw connection in hole on the rotary shaft, when user installation, as soon as every disassembly pre- cartridge screw, loads onto one
The screw of fixed main shaft, three screws successively change;But this device still remains following disadvantage:
It is well known that triangle has stability, pedestal is set to be connected with rotary shaft with three pre- cartridge screws of radial equipartition, but
When client installs, this three screws are successively changed respectively, and every disassembly one makes attachment screw only be left two, two screws
The center of main shaft and pedestal can be generated offset, lead to centre deviation, can not position by connection;The problem will will cause defeated
The influence of signal out causes the precision of encoder to be lost and even fails.
Summary of the invention
It is an object of the invention in view of the above-mentioned drawbacks in the prior art, provide a kind of installation of integral type without built-in axis
Hold encoder.
Its main operational principle is that corresponding position is arranged by the way that special screw thread fixation hole is arranged in shaft, and on the base
For the radial through-hole that the installation tool of fixing screws passes through, make shaft in installation fixation procedure always in equally distributed three
A pre- cartridge screw keeps locking in reached equilibrium state, relative displacement will not occur with pedestal, ensure that installation accuracy.
To achieve the above object, the invention adopts the following technical scheme: encoder of the integral type without built-in bearing, including base
Holder assembly and rotor assembly, the base assembly are made of pedestal and the PCBA board being arranged on pedestal, and the pedestal and
The PCBA board constitutes sealing cavity configuration, and the rotor assembly is by shaft and the indexing code-disc group being fixed on the shaft
At the rotor assembly is arranged in the base assembly, spindle mounting hole is provided at the axle center of the shaft, feature exists
In: it is circumferentially uniformly distributed on the circumference of the pedestal to pre-install hole there are three the screw thread being disposed radially, on the circumference of the shaft
Circumferentially uniformly distributed there are three radial blind holes, the screw thread prepackage is provided with pre- cartridge screw in hole, and the pre- cartridge screw passes through institute
It states screw thread prepackage hole to penetrate the pedestal and protrude into the radial blind holes, fixes the shaft with the pedestal, described turn
It has been disposed radially at least one threaded securing bores on the circumference of axis, fixing screws are provided in the threaded securing bores, it is described
Radial through-hole, the quantity of the radial through-hole and institute are provided on the circumference of pedestal, with the threaded securing bores opposite position
The quantity for stating threaded securing bores is equal.
Further, the quantity of the threaded securing bores is two, and the radial direction difference 90 of two threaded securing bores
Degree.
Further, the bottom surface of the radial blind holes is plane, and the bottom surface of radial blind holes is parallel to the axial direction of pedestal.
The present invention compares with prior art, and effect is positive and apparent.The configuration of the present invention is simple is effectively ensured
Installation accuracy, while having the advantages that installation environment requirement is low, installation cost is greatly saved.
