Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the elastic body of the existing column type weighing sensor is prone to inclination after being impacted by the lateral load during use and cannot be automatically reset, resulting in inaccurate weighing and damage to the sensor and making it unusable. Self-resetting column load cell can effectively solve the above problems

Embodiment 1

[0021] Such as Figure 1 to Figure 4 As shown, a self-resetting column load cell includes a columnar elastic body 1 , an indenter 3 , and a bearing base 4 . The columnar elastic body 1 has a cylindrical structure. The lower end of the columnar elastic body 1 is connected to the bearing base 4 . The pressure head 3 is arranged on the upper end of the columnar elastic body 1 . A first groove 7 is provided on the side of the indenter 3 close to the columnar elastic body 1 , and the upper end of the columnar elastic body 1 is inserted into the first groove 7 . The upper end surface of the columnar elastic body 1 is a downwardly concave first concave spherical surface, and the bottom surface of the first groove 7 is a downwardly protruding first convex spherical surface. The spherical radius of the first concave spherical surface is greater than the spherical radius of the first convex spherical surface, and the first concave spherical surface and the first convex spherical surf...

Abstract

The invention discloses a self-resetting column type weighing sensor comprising a columnar elastomer, a pressing head and a bearing base. The lower end of the columnar elastomer is connected to the bearing base, the pressing head is arranged at the upper end of the columnar elastomer, and a strain gauge is arranged on the columnar elastomer. A second groove is formed in the bearing base, the lowerend of the columnar elastomer is inserted into the second groove, and a reset mechanism for resetting the columnar elastomer is arranged between the columnar elastomer and the bearing base. Accordingto the invention, since the reset mechanism is arranged between the columnar elastomer and the bearing base, the columnar elastomer can automatically reset under the action of the reset mechanism when the elastomer inclines after being impacted by a transverse load and then the transverse load disappears, thereby avoiding the situation that the columnar elastomer cannot be used due to permanent inclination.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a self-resetting column type weighing sensor. Background technique [0002] At present, column load cells are widely used in various electronic weighing equipment such as truck scales, rail scales, axle load scales, and tank scales. The existing column type load cell includes a bearing base, an elastic body, and an upper pressure head. The elastic body is columnar, and a strain gauge is arranged on the elastic body. The base is installed on the weighing device. When weighing, the load is applied to the indenter and transmitted to the elastic body through the indenter. After the elastic body is loaded, it will deform to a certain extent. The elastic body deforms and deforms, and the strain gauge converts the deformation into an electrical signal and transmits it to the processing system. The control system can obtain the actual weight data of the object after calculation and proc...
