The whole sensor detector has compact structure, reasonable arrangement, low cost, higher detection efficiency and detection precision and convenient operation and use. The sensor detector is an ideal detecting apparatus for force sensors.
Description
[technical field]
The utility model relates to a kind of pick-up unit, is specifically related to a kind of testing sensor performance detection device that is used for.
[background technology]
Power value sensor application is extensive, yet, exist the problem that detects with the demarcation difficulty for large-tonnage power value sensor always.
The checkout equipment joint structure complexity of present existing large-tonnage power value sensor, bulky, complicated operation, and accuracy of detection is not high, and these defectives have hindered the application of large-tonnage power value sensor.
So developing the sensor detecting device that a nested structure is simple, cost is low and have than high measurement accuracy has become the technical matters that needs to be resolved hurrily in the art.
[utility model content]
In order to solve the above-mentioned deficiency of prior art, the utility model purpose is to provide a kind of sensor detecting device.
For achieving the above object, the technical scheme that provided of one of the utility model embodiment is:
A kind of sensor detecting device comprises:
One test section has an incorporating section and can hold a sensor in it, be provided with an oil cylinder and a push rod in the described test section, and the described push rod of described hydraulic oil cylinder driving slides to give sensor one thrust;
One force section, described force section is connected to form successively by a servo motor, a reductor, a screw pair, a plunger case, and described plunger case is connected by an oil pipe with described oil cylinder;
One oil supply portion is made up of an oil-feed pump and an oil dropping apparatus, and described oil supply portion is connected with described test section and described force section by described oil pipe;
One detecting device is arranged on the described plunger case, detects the displacement of described plunger case.
Described detecting device is a displacement transducer.
Based on the design of the foregoing description, advantage of the present utility model is: whole apparatus structure compactness, rationally distributed, cheap, have higher detection efficient and accuracy of detection, and whole device is easy for operation.
Other purposes of the present utility model and advantage can be further understood from the disclosed technical characterictic of the utility model.State with other purposes, feature and advantage and can become apparent on the utility model for allowing, embodiment cited below particularly also cooperates appended graphicly, is described in detail below.
[description of drawings]
Fig. 1 is the structural representation of the sensor detecting device of one of the utility model embodiment.
[embodiment]
About addressing other technologies content, characteristics and effect before the utility model, in the following detailed description that cooperates with reference to graphic embodiment, can clearly present.The direction term of being mentioned in following examples, for example: upper and lower, left and right, front or rear etc. only are the directions with reference to annexed drawings.Therefore, the direction term of use is to be used for illustrating not to be to be used for limiting the utility model.
Please refer to shown in Figure 1, a kind of sensor detecting device 1 of an embodiment of the present utility model, comprise a test section 11, have an incorporating section 111 in it and can hold a sensor, be provided with an oil cylinder 112 and a push rod 113 in the test section 11, oil cylinder 112 drives push rod 113 and slides to give sensor one thrust; One force section 12, force section 12 is connected to form successively by a servo motor 121, a reductor 122, a screw pair 123, a plunger case 124, and plunger case 124 is connected by an oil pipe 14 with oil cylinder 112.One oil supply portion 13 is made up of an oil-feed pump 131 and an oil dropping apparatus 132, and oil supply portion 13 is connected with test section 11 and force section 12 by oil pipe 14; One detecting device 15 is arranged on the plunger case 124 displacement of test column plug cylinder 124.
In the present embodiment, detecting device 15 is a displacement transducer.
The principle of work of whole device is as follows:
At first device is proofreaied and correct, correcting sensor is added on the incorporating section 111 in the test section 11, oil-feed pump 131 by oil pipe 14 to oil cylinder 113 oilings, push rod 112 beginning fast rise, very near correcting sensor the time, oil-feed pump 131 quits work.At this moment the servomotor 121 of controlling plunger case 124 brings into operation.Servomotor 121 is by the reductor 122 of big retarding ratio, then by feed screw nut pair 123 transmissions, drives plunger case 124 and carries out microfeed, guaranteed that the power value slowly rises to corrected value after, plunger case 124 quits work.The displacement of displacement transducer 15 real-time test column plug cylinders 124 can draw corresponding oil cylinder 113 power values with the relation value between plunger case 124 displacements.
When detecting, tested sensor is added on the incorporating section 111 in the test section 11, oil-feed pump 131 by oil pipe 14 to oil cylinder 113 oilings, push rod 112 beginning fast rise, when very approaching tested sensor, oil-feed pump 131 quits work.At this moment the servomotor 121 of controlling plunger case 124 brings into operation, and drives plunger case 124 and carries out microfeed.Displacement transducer 15 detects the displacement of plunger case 124, with the relation value between plunger case 124 displacements, converses the power value of oil cylinder 113 according to existing oil cylinder 113 power values, can detect tested sensor easily like this.
Though the utility model discloses as above with preferred embodiment; so it is not to be used for limiting the utility model; anyly have the knack of this skill person; in the spirit and scope that do not break away from the utility model; when can doing a little change, so the protection domain of the utility model is as the criterion when looking the patent protection scope person of defining.In addition, arbitrary embodiment of the present utility model or claim must not reached whole purposes or advantage or the characteristics that the utility model discloses.In addition, summary part and title only are the usefulness that is used for assisting the patent document search, are not the rights protection scope that is used for limiting the utility model.
