Abstract
The utility model discloses a sensor used for a steelyard. The sensor comprises an elastic body, a sealing cover plate and a strain gauge; the elastic body comprises a working body and a bearing ring arranged at the upper part of the working body, wherein the bearing ring and the working body are integrally molded. According to the sensor used for the steelyard of the utility model, the bearing ring and the working body are integrally molded; and the sensor used for the steelyard has the advantages of simple structure, low price, improved precision, and improved installation speed.
Description
Technical field
The utility model relates to the steelyard technical field, relates in particular a kind of steelyard sensor.
Background technology
Existing steelyard generally comprises suspension ring, sensor, suspension hook, circuit etc., Granted publication CN 201003972Y, the Chinese utility model patent of 2008.01.09 day Granted publication day discloses a kind of sensor special for hanging balance, comprise the suspension ring that connect successively, sensor elastomer and suspension hook, suspension ring directly are connected to the top of sensor elastomer, the sensor elastomer bottom is connected with suspension hook by bolt, stress hole one side of sensor elastomer bottom also is provided with and makes the outside surface that is bolted to behind the position keep the counterbore that flushes, steelyard sensor construction after the improvement is compacter, process conveniently, compare with original structure and more to save material, reduce production costs, overall weight alleviates, better satisfying the market requirement.But, find that in use it should the Shortcomings part: overall performance not, precision should be not, especially angular errors is larger.
The utility model content
The purpose of this utility model provides for the deficiencies in the prior art part, and a kind of steelyard sensor is provided, and can overcome the deficiencies in the prior art part, and it is simple in structure, cheap, and measuring accuracy is high, long service life.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of steelyard sensor, comprise elastic body, seal cover board and strainometer, described elastic body comprises working body and is arranged on the carrier bar on described working body top, and described carrier bar and described working body is one-body molded makes.
The applicant finds after through repeatedly research and experiment, existing steelyard sensor, its precision is good not, error ratio is larger, is that present elastic body separates manufacturing with suspension ring because of the reason of elastic body and suspension ring, assemble more time-consuming, increased cost, the more important thing is, suspension ring and elastic body are separately made, and then assembling, precision certainly will will be subject to processing, assembly technology, assembly precision, the assembly crewman, manufacture craft, make the impact of the many factors such as material, these combined factors are got up, just so that after suspension ring and the elastic body assembling, various problems appear, such as the inevitably gapped existence of meeting between suspension ring and the sensor, for another example, suspension ring installation site out of true, for another example, firmly excessive when suspension ring are installed, cause suspension ring that tension is installed, these factors have seriously influenced the precision of sensor, for this reason, the applicant is with carrier bar and working body is one-body molded makes, and the shortcoming above having avoided has improved the precision of sensor.
As preferably, described elastic body is formed by the high strength alloy steel forging dies.
As preferably, described working body comprises for the connecting portion that is connected with suspension hook and the strain regions that is connected with described carrier bar.
As preferably, described strain regions comprises response body and is arranged on strain bore on the described response body.
As preferably, described strain regions comprises response body and is arranged on strain bore on the described response body.
As preferably, described strain bore is through hole.
As preferably, described strain bore is blind hole.
As preferably, described strain bore is blind hole, and the bottom of described blind hole is provided with a plurality of connecting through holes.
As preferably, described strain regions is a cylinder.
As preferably, described strain bore is through hole, is provided with the cruciform demarcation strip in the described through hole.
The utility model beneficial effect is:
Sensor of the present utility model, carrier bar and working body are one-body molded to be made, simple in structure, cheap, has improved the precision of sensor, has improved the installation rate of sensor.
