Abstract
The utility model discloses a self support type weight sensor, which comprises a strain rod body 1, a strain piece 2 arranged on the strain rod body 1 and a frame 3. The tail end of the strain rod body 1 is connected with the frame 3, and the bottom surface of the frame 3 is used as the stress bearing surface 4 of the entire weight sensor of the self support type. The weight sensor of the self support type is characterized in that the top surface of the top end of the strain rod body 1 is provided with a stress support plate 5, the top part of the stress support plate 5 is provided with another bearing surface 6, and the bearing surface 6 is positioned above the frame 3. The weight sensor of the self support type can effectively eliminate the unnecessary moment borne when the metal strain rod bears the load and effectively eliminate the occurrence of the return-to-zero error and the hysteresis error. The weight sensor of the self support type has the advantages of simple structure, convenient installation and manufacturing, and lower cost.
Description
1, technical field:
The utility model relates to the self supporting type weight sensor.
2, background technology:
At present, use LOAD CELLS generally with the form of independent Metallic rod on the electronic scales, foil gauge is installed on the Metallic rod, foil gauge connects an electronic circuit so that the distortion that foil gauge is produced converts electric signal to, because the application point that is weighed may be setovered with sensor, thereby make sensor bear unwanted moment, influence measuring accuracy, owing to bear the distortion that unnecessary moment produces different directions, cause back the appearance of zero error and hysteresis error, in this scale, the Metallic rod two ends must be rigidly attached on the base of scale, and load acts directly on the Metallic rod and by Metallic rod acting force is sent on the base.
3, summary of the invention:
The purpose of this utility model provides the self supporting type weight sensor, and it is effectively eliminated the metal strain bar and bear unnecessary moment when bearing load, effectively eliminates back the appearance of zero error and hysteresis error, simple in structure, install easily manufacturedly, cost is lower, and practicality is stronger.
The utility model is achieved by the following technical solution: it comprises the strain body of rod, is installed in foil gauge and framework on the strain body of rod, the tail end of the strain body of rod is connected with framework, the bottom surface of framework is as the stressed loading end of whole sensor, install on the end face on the top of the strain body of rod and connect stressed support plate, the top of stressed support plate is provided with another loading end, and loading end is positioned on the framework.
Above-mentioned described stressed support plate is by the top of rivet at the strain body of rod.
Above-mentioned described framework can be rectangle, " [" shape or circular arc.
The top loading end of above-mentioned described stressed support plate is positioned at the top at strain body of rod middle part.
The above-mentioned described strain body of rod is positioned at the centre of framework.
The utility model compared with prior art has following advantage: 1) stressed support plate of the present utility model is positioned on the framework, and is convenient when installing and using; 2) stressed support plate is positioned at directly over the strain body of rod, when stressed support plate bears load, power is delivered to the change body of rod, effectively eliminates the metal strain bar and bear unnecessary moment when bearing load, and measuring accuracy is more increased; 3) the strain body of rod stress deformation of this structure is comparatively regular, effectively eliminates back the appearance of zero error and hysteresis error; 4) simple in structure, easily manufactured, cost is lower.
4, description of drawings:
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is that the another kind of the utility model framework is implemented structural representation.
5, embodiment:
As shown in Figure 1 and Figure 2, the utility model comprises the strain body of rod 1, is installed in foil gauge 2 and framework 3 on the strain body of rod 1, the tail end of the strain body of rod 1 is connected with framework 3, the bottom surface of framework 3 is as the stressed loading end 4 of whole sensor, install on the end face on the top of the strain body of rod 1 and connect stressed support plate 5, the top of stressed support plate 5 is provided with another loading end 6, and loading end 6 is positioned on the framework 3.Stressed support plate 5 is the tops that are riveted on the strain body of rod 1 by rivet 7.Framework 3 can be rectangle, " [" shape or circular arc.The top loading end 6 of stressed support plate 5 is positioned at the top at the strain body of rod 1 middle part.The strain body of rod 1 is positioned at the centre of framework 3.
