Fig. 1 is an overall schematic diagram of a force measuring mechanism with a self-protection function of the sensor.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
In the figure, a force measuring plate 1, a pressure sensor 2, a connecting screw 3, a connecting nut 4, a limiting screw 5, a fixed guide sleeve 6, a fixed plate 7, a spring 8, a movable guide sleeve 9, a floating plate 10, a guide post 11 and a protection assembly 12 are arranged.
As shown in figure 1, the force measuring mechanism with the self-protection function of the sensor comprises a fixed plate 7, a floating plate 10 and a force measuring plate 1, wherein a pressure sensor 2 is arranged between the floating plate 10 and the force measuring plate 1, the pressure sensor 2 is arranged on the floating plate 10, the detection point of the pressure sensor 2 is contacted with the force measuring plate 1, a limit screw 5 is arranged on the fixed plate 7, the limit screw 5 penetrates through the floating plate 10 and limits the force measuring plate 1, guide posts 11 are respectively arranged on two sides of the fixed plate 7, the floating plate 10 and the force measuring plate 1, the device is characterized in that a protection component 12 is arranged on the guide post 11, the protection component 12 comprises the guide post 11, a movable guide sleeve 9 and a fixed guide sleeve 6, the force measuring plate 1 is installed at the lower end of the guide post 11 through a connecting screw 3, a connecting nut 4 is locked at the upper end of the guide post 11, a spring 8 is installed between the movable guide sleeve 9 and the fixed guide sleeve 6, and the floating of the floating plate 10 is realized by the spring 8.
When the pressure sensor 2 is assembled, the pressure sensor 2 is installed on the floating plate 10, the detection point of the pressure sensor 2 is in contact with the force measuring plate 1, when the force measuring plate 1 is stressed, force can be reacted on the pressure sensor 2, the purpose of pressure detection is achieved, the floating plate 10 is connected with the fixed plate 7 through the guide pillar 11, the movable guide sleeve 9 and the fixed guide sleeve 6, the force measuring plate 1 is installed at the lower end of the guide pillar 11 through the connecting screw 3, the connecting nut 4 is locked at the upper end of the guide pillar 11, the spring 8 is installed between the movable guide sleeve 9 and the fixed guide sleeve 6, floating of the floating plate 10 is achieved, the limiting screw 5 is installed on the fixed plate 7, penetrates through the floating plate 10, and plays a limiting role in.
In the initial state, a certain gap is reserved between the limiting screw 5 and the force measuring plate 1. The product of the distance of the gap and the elastic coefficient of the spring 8 is less than or equal to the range of the pressure sensor 2, when the force measuring plate 1 measures the force, the force measuring plate 1 and the connecting screw 3, the guide pillar 11, the movable guide sleeve 9, the floating plate 10 and the pressure sensor 2 move upwards together, the compression spring 8 is compressed, when the floating plate 10 moves to the upper limit position, the length of the compression spring 8 is up to the contact of the force measuring plate 1 and the limiting screw 5, the measured pressure is the maximum detection pressure of the whole mechanism, when the pressure borne by the force measuring plate 1 is continuously increased, the limiting screw 5 supports against the force measuring plate 1 to offset the extra pressure, so that the pressure borne by the pressure sensor 2 is always within the range of the range, and the effect of protecting the pressure sensor 2 is realized.
