Description
Technical field
Sensor Design technical field is the utility model is related to, more particularly to a kind of weighing elastic body.
Background technology
Electronic weighing appliance suffers from extremely being widely applied in all trades and professions, and weighing elastic body is on electronic weighing appliance
A very important part, it directly decides the measurement order of accuarcy of these equipment, traditional weighing elastic body material
Low intensity, not high to the sensitiveness of strain, the degree of accuracy for causing weighing-appliance to weigh is low, and traditional weighing elastic body paster is answered
Miscellaneous, foil gauge is fragile, and service life is short, therefore designs a kind of intensity height, and strain sensitivity is strong, and property really of weighing is high, technique
Simply, the weighing elastic body of service life length seems very necessary.
Utility model content
The purpose of this utility model is exactly in order to overcome traditional weighing elastic body strength of materials low, to the sensitiveness of strain
The defects of low, the degree of accuracy weighed is low, and paster is complicated, and foil gauge is fragile, and service life is short, devises one kind and weigh elasticity
Body, intensity is high, and strain sensitivity is strong, and property really of weighing is high, and technique is simple, service life length.
The required technical problem solved of the utility model can be achieved through the following technical solutions：
A kind of weighing elastic body, including matrix, foil gauge, described matrix are a cuboid, and the strain gauge adhesion is in institute
State on matrix, described matrix is machined with spherical pit, fixing post hole, cylindricality counterbore, and the spherical pit processing is in described matrix
Upper surface centre position, the spherical pit is the stress point of the weighing elastic body, on the matrix positioned at the spherical female
The both sides in hole are drilled with the fixing post hole respectively, and the cylindricality counterbore is machined with the side of described matrix, and the foil gauge is
It is pasted onto the bottom surface of the cylindricality counterbore.
Described matrix is made of alloy steel material.
The cylindricality counterbore is in the respectively processing two of former and later two sides of matrix.
The foil gauge is pasted onto the bottom surface of the cylindricality counterbore using bonding agent.
The cylindricality counterbore is sealed using laser welding technology to it again.
As a result of above technical scheme, the utility model has the following advantages that：
Designed weighing elastic body is combined using matrix, foil gauge, matrix is made of alloy steel material, when weighing
Ensure that body has enough intensity, prevent the overweight damage for causing weighing elastic body of weighed object, cylindricality counterbore is before matrix
Latter two side respectively processes two, and foil gauge is posted in each cylindricality counterbore, improves weighing elastic body to weighed object weight
Sensitiveness, ensure the accuracy weighed, foil gauge is pasted onto the bottom surface of cylindricality counterbore, strain gauge adhesion jail using bonding agent
Gu easy to operate, cylindricality counterbore is sealed using laser welding technology to it again so that extraneous liquid etc. influences foil gauge
The impurity of performance cannot be introduced into cylindricality counterbore, the service life of foil gauge is high.
Brief description of the drawings
Fig. 1 is the utility model structure front-view schematic diagram；
Each component and reference are respectively in figure：1st, matrix；2nd, foil gauge；3rd, spherical pit；4th, fixing post hole；5th, post
Shape counterbore.
