Abstract
The utility model discloses a kind of Zhou Xin dilatometry mechanism, comprise body, the bearing be arranged in body, axle core, the sensor be fixed by screws on body; Described axle core is inserted in the inner ring of bearing, and can rotate relative to body; The outside of described axle core has been threaded detection dish and retainer nut, and described detection dish is clamped between the inner ring of bearing and retainer nut; This sensor is for the distance between detection dish and sensor.The annexation of the utility model by rationally arranging between sensor and body, between detection dish and axle core, makes the installation of sensor, detection dish simple and convenient, also can guarantee the installation stability of sensor, detection dish; In addition, by utilizing the cooperation of sensor, detection dish, can contactless measurement be adopted, causing to avoid wearing and tearing occur and measuring inaccurate problem.
Description
Technical field
The utility model relates to a kind of Zhou Xin dilatometry mechanism.
Background technology
Main shaft generally comprises body, is positioned at the axle core of body, and in axle core rotation process, can generate heat to producing and expand.In order to the expansion elongation of shaft core can be obtained, sensor and detection part that is corresponding with sensor and that detect for sensor are installed in main shaft of being everlasting, but the installation of this sensor, detection part is comparatively loaded down with trivial details, brings inconvenience to user.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Zhou Xin dilatometry mechanism, and its annexation by rationally arranging between sensor and body, between detection dish and axle core, makes the installation of sensor, detection dish simple and convenient.
For solving the problem, the technical scheme that the utility model adopts is as follows:
Zhou Xin dilatometry mechanism, comprises body, the bearing be arranged in body, axle core, the sensor be fixed by screws on body; Described axle core is inserted in the inner ring of bearing, and can rotate relative to body; The outside of described axle core has been threaded detection dish and retainer nut, and described detection dish is clamped between the inner ring of bearing and retainer nut; This sensor is for the distance between detection dish and sensor.
Described body is provided with through wires hole, and the signal wire of sensor stretches out in outside body through through wires hole.
Described body comprises main casing, the end cap be bolted on main casing openend, and described bearing is arranged in main casing, and described sensor is fixed on end cap.
Described retainer nut is supported at detection dish on the side of axle core.
Described detection dish and sensor are oppositely arranged.
Described detection dish, sensor are arranged along the axially spaced-apart of axle core.
Compared to existing technology, the beneficial effects of the utility model are:
The annexation of the utility model by rationally arranging between sensor and body, between detection dish and axle core, makes the installation of sensor, detection dish simple and convenient, also can guarantee the installation stability of sensor, detection dish; In addition, by utilizing the cooperation of sensor, detection dish, can contactless measurement be adopted, causing to avoid wearing and tearing occur and measuring inaccurate problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1, axle core; 2, retainer nut; 3, screw; 4, sensor; 5, detection dish; 6, body; 7, end cap; 8, bolt.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further, understands the utility model technical thought required for protection so that clearer.
As shown in Figure 1, be Zhou Xin dilatometry mechanism of the present utility model, comprise body 6, the bearing be arranged in body 6, axle core 1, the sensor 4 be fixed on by screw 3 on body 6; Described axle core 1 is inserted in the inner ring of bearing, and can rotate relative to body 6; The outside of described axle core 1 has been threaded detection dish 5 and retainer nut 2, described detection dish 5 is clamped between the inner ring of bearing and retainer nut 2, and can avoid occurring in axle core 1 rotation process that detection dish 5 gets loose phenomenon, to guarantee the stability that detection dish 5 is installed by the effect that holds out against of retainer nut 2 to detection dish 5; This sensor 4 is for the distance d between detection dish 5 and sensor 4.
Concrete, described body 6 is provided with through wires hole, and the signal wire of sensor 4 stretches out in outside body 6 through through wires hole.
Preferably, described body 6 comprises main casing, the end cap 7 be fixed on by bolt 8 on main casing openend, and described bearing is arranged in main casing, and described sensor 4 is fixed on end cap 7.And by adopting said structure, the dismounting of sensor 4 can be made more simple and convenient.
Concrete, described retainer nut 2 is supported at detection dish 5 on the side of axle core 1, and this detection dish 5 is also provided with the recess embedded for retainer nut 2 on the side near axle core 1.
Concrete, described detection dish 5 is oppositely arranged with sensor 4.Preferably, described detection dish 5, sensor 4 are arranged along the axially spaced-apart of axle core 1.
In use, the distance d between sensor 4 detection dish 5 and sensor 4 can be utilized, thus the signal that can export according to sensor 4 calculates the expansion elongation of shaft core 1.And the utility model is by rationally arranging the annexation between sensor 4 and body 6, between detection dish 5 and axle core 1, makes the installation of sensor 4, detection dish 5 simple and convenient, also can guarantee the installation stability of sensor 4, detection dish 5; In addition, by utilizing the cooperation of sensor 4, detection dish 5, can contactless measurement be adopted, causing to avoid wearing and tearing occur and measuring inaccurate problem.
Above-mentioned embodiment is only preferred implementation of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
