A three-dimensional pressure sensor

Abstract

The invention discloses a three-dimensional pressure sensor, which comprises a sensor main body and a connecting flange fixedly connected to the upper and lower ends of the sensor main body. The outer surface of the sensor main body is provided with a wiring port for data transmission. A locking mechanism is provided at the center of the surface, a built-in installation groove is provided on the outer surface of the upper end of the connecting flange, the locking mechanism is located at the center of the built-in installation groove, and a displacement groove is opened inside the built-in installation groove, and One side of the displacement groove is provided with a movable groove, the displacement groove communicates with the movable groove, the inside of the movable groove is movably connected with a connecting plate, and the inside of the displacement groove is provided with a connecting block. Compared with the traditional three-dimensional In terms of the installation structure of the pressure sensor, the connection flanges at both ends of the three-dimensional pressure sensor are improved to solve the multi-position perforated installation and fixation method of the transmission. Compared with the traditional perforated connection method of the connection flange, this device has a wider application range.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a three-dimensional pressure sensor. Background technique [0002] Pressure sensors are devices that convert the physical deformation of pressure-sensitive materials into electrical signals, and are widely used in medicine, robotics, aerospace, and industrial production. When a pressure acts on the surface of an object, the contact surface will receive a stress of equal magnitude and opposite direction from the inside of the object, which is called interface stress. This kind of pressure can be divided into two types according to the direction of action. The pressure perpendicular to the interface is called positive pressure (usually one-dimensional, denoted as Z direction), and the pressure parallel to the interface is called shear force (usually two-dimensional, denoted as X). direction and Y direction). In practical applications, most of the pressure is neither perpendicular...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that at least the following problems in the prior art have not been solved: 1. The traditional three-dimensional force sensor uses flanges at both ends to drill holes and tap holes and bolts to meet external requirements during installation. The installed equipment is installed and fixed, and then in the actual use process, because the installation holes on the equipment may not completely correspond to the installation holes of the three-dimensional pressure sensor with different specifications, the traditional three-dimensional pressure sensor is often connected at both ends at the beginning of production. The mounting holes of two specifications are processed on the flange. This method will not only destroy the overall strength of the original connecting flange, but also easily cause deviation of the drilling angle during the production of the connecting flange, which is not only time-consuming and laborious, but also defective products 2. At the same time, the connection flanges at both ends of the traditional three-dimensional pressure sensor are important components in the installation process of the three-dimensional pressure sensor and other equipment, but the flange plate required for connection Once the tapping angle deviation is caused when the hole is tapped, the installation point cannot be installed and fixed, resulting in the overall installation of the three-dimensional pressure sensor cannot be fixed, which will affect the actual use, reduce the accuracy of the measured value, and thus affect the normal operation of the equipment
