Problems solved by technology

The existing torque sensor is too bulky to be used in dental equipment, and the pressure sensor used in industry can only measure one axis, which makes it unable to meet the needs of use. Therefore, it is necessary to design a small volume, multi-axis , high-sensitivity force feedback sensor to meet the needs of dental equipment

Embodiment Construction

[0010] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with embodiments. The present embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0011] The embodiment of the present invention provides a dental sensor that can measure force feedback. The sensor is of a sleeve type design. The body of the sensor is divided into an inner cylinder and an outer outer cylinder. Two sets of mutually perpendicular strain gauges are arranged on the wall, a set of strain gauges are arranged on the bottom of the cylinder, and the three sets of strain gauges are respectively located on the X-axis, Y-axis and Z-axis of the cylinder body, so that three sets of strain The plates are perpendicular to each other. The outer cylinder is a support structure that supports the deformable structure connected to the strain gage...

Abstract

The invention discloses a dental sensor capable of measuring force feedback. The dental sensor is in a sleeve type design, and comprises a body, wherein the body is composed of an internal cylinder and an external outer barrel, two groups of strain gauges perpendicular to each other are arranged on the inner side wall of the cylinder, a group of strain gauges is arranged at the bottom part of thecylinder, the three groups of strain gauges are positioned on X-axis, Y-axis and Z-axis of a cylinder body separately, so that the three groups of strain gauges are perpendicular to one another, the outer barrel is a supporting structure and supports a deformable structure connected with the strain gauges, and supporting structures at positions of three strain gauges are independent of one anotherand are connected on measuring rods separately, such that the supporting structures of the strain gauges on the X-axis, Y-axis and Z-axis are independent of one another. The dental sensor disclosed by the invention can measure the magnitude of forces in multiple axial directions simultaneously, and can calculate the size of moment in each direction precisely by means of an embedded system.

Description

Technical field [0001] The invention relates to the technical field of sensors, in particular to a dental sensor capable of measuring force feedback. Background technique [0002] Sensors that can measure force feedback are mainly used to measure the torque of the measured object. Traditional mechanical sensors are mostly sensors that measure the pressure, tension, torque, acceleration, and angular velocity of the measured object, and few directly measure and calculate the torque. Sensor. The existing torque sensor is too large to be used in dental equipment, and the pressure sensor used in industry can only measure one axis, making it unable to meet the needs of use, so it is necessary to design a small volume, multi-axis , High-sensitivity force feedback sensor to meet the needs of dental equipment. Summary of the invention [0003] Aiming at the shortcomings of the prior art, the present invention provides a dental sensor capable of measuring force feedback, which can simulta...
