Description
Technical field
The utility model relates to a kind of self-adaptation accurate positioning device detected for angle.
Background technology
At present in lathe or construction implement field, high-precision angle orientation generally adopts scrambler, grating scale and magnetic railings ruler angularly sensor.But have in the middle part of the rotation of rotary body and stop when the comparatively general scrambler of application can not be directly installed, we can select the grating scale of girdle type, magnetic railings ruler and the steel grid chi that adopt, but above-mentioned three all very expensive the and installation accuracy of price require high cause installing very difficult, after breaking down or damaging, maintenance or to replace difficulty large; Also can adopt the mode of mechanical switch, indirectly carry out detection angles, but precision may be caused not high due to the reason of machine error or installation deviation, even cannot meet the demands.
Summary of the invention
The technical problems to be solved in the utility model is, there is rotation middle part for existing rotary body has stop directly can not install scrambler, and sensor installation accuracy requires high, that installation is difficult, maintenance replacement difficulty is large deficiency, a kind of self-adaptation accurate positioning device detected for angle is provided, accuracy of detection is high, and maintenance or replacement are conveniently.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of self-adaptation accurate positioning device detected for angle, it comprises gear ring, gear, angular transducer and elasticity connection bracket, described gear ring is fixedly connected on rotary body rotor, described gear is connected on rotary body stator by elasticity connection bracket, gear ring and gear are by engaging compact siro spinning technology, and described angular transducer is arranged on and is inserted on the central shaft of gear.
By such scheme, described elasticity connection bracket is made up of connection sliding block, fixing chute and holddown spring, one end of connection sliding block and the central shaft being inserted in gear and the bearing being enclosed within central shaft two ends are connected and fixed, and the other end of connection sliding block is connected with holddown spring through fixing chute and holds out against.
By such scheme, the rotating shaft of described angular transducer is connected to the extension of the central shaft being inserted in gear by axle sleeve, angular transducer shell body is fixed on connection sliding block by base bolt.
By such scheme, described gear ring is fixedly connected on rotary body rotor by bolt or rivet.
By such scheme, described gear ring forms a whole circle (gear ring can be a whole circle, also conveniently can dismantle and be made up of some sections of arc sections) by some gear ring arc sections.
Principle of work of the present utility model: when rotary body stator and rotary body relative rotation of rotor certain angle, gear ring and gear produce relative motion thereupon, drives angular transducer to rotate, thus accurately detects rotational angle.Connection sliding block can slidably reciprocate under the pressure effect of holddown spring in fixing chute, ensures that gear closely engages with gear.
Compared with prior art the utility model has following characteristics and beneficial effect: the situation having stop in the middle part of the rotation that this device can be applicable to rotary body, and the not high situation of installation accuracy can be adapted to, also good accuracy of detection can be obtained, simultaneously after breaking down or damaging, keep in repair or replace comparatively simple and convenient.

In figure: 1-gear ring, 1a-gear ring arc section, 2-gear, 3-elasticity connection bracket, 3a-connection sliding block, 3b-fix chute, 3c-holddown spring, 4-sensor, 5-rotary body stator, 6-rotary body rotor, 7-central shaft, 8-base.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
With reference to shown in Fig. 1 ~ Fig. 3, the self-adaptation accurate positioning device detected for angle described in the utility model, it comprises gear ring 1, gear 2, angular transducer 4 and elasticity connection bracket 3, described gear ring 1 is fixedly connected on rotary body rotor 6 by the securing member such as bolt or rivet, described gear 2 is connected on rotary body stator 5 by elasticity connection bracket 3, gear ring 1 and gear 2 are by engaging compact siro spinning technology, and described angular transducer 4 is arranged on and is inserted on the central shaft 7 of gear 2.
Described elasticity connection bracket 3 is made up of connection sliding block 3a, fixing chute 3b and holddown spring 3c, one end of connection sliding block 3a and the central shaft 7 being inserted in gear 2 and the bearing being enclosed within central shaft 7 two ends are connected and fixed, and the other end of connection sliding block 3a is connected with holddown spring 3c through fixing chute 3b and holds out against.
The rotating shaft of described angular transducer 4 is connected to the extension of the central shaft 7 being inserted in gear by axle sleeve, angular transducer 4 shell body is fixed on connection sliding block 3a by base 8 bolt.
Described gear ring 1 can be a whole circle, also can be divided into some gear ring arc section 1a, as shown in Figure 3, facilitates installation, maintenance and change.
During work, when rotary body stator 5 and rotary body rotor 6 relatively rotate certain angle, gear ring 1 and gear 2 produce relative motion thereupon, drive angular transducer 4 to rotate, thus accurately detect rotational angle.
When causing gear ring 1 to contact not tight with gear 2 due to alignment error or malformation, connection sliding block 3a skids off automatically under the pressure effect of holddown spring 3c in fixing chute 3b, driven gear 2 holds out against gear ring 1, thus ensure that gear ring 1 closely engages with gear 2, prevent and lose tooth and affect accuracy of detection; When gear ring 1 contacts tension with gear 2, holddown spring 3c is compressed, and connection sliding block 3a slips into automatically under both squeezing actions in fixing chute 3b, prevents from damaging by pressure the central shaft 7 or fixed support that are inserted in gear 2.
Above-describedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the present invention with this, therefore according to the equivalence change that the utility model claim is done, still belong to protection domain of the present utility model.
