Portable device for detecting torque and rotating speed of dental equipment

Abstract

The invention relates to a portable device for detecting a torque and a rotating speed of dental equipment. The device comprises a shell, a main driving circuit board, a hysteresis brake, a driven shaft and a torque transmission coupler. The hysteresis brake is fixedly connected with the tail end of the driven shaft so that the driven shaft can drive a hollow cup rotor of the hysteresis brake to rotate; and a controller is arranged on the main driving circuit board, the hysteresis brake is electrically connected with the controller, a driven shaft through hole is formed in the shell so that the front end of the driven shaft can stretch out of the shell and is fixedly connected with the torque transmission coupler, a plurality of magnets are evenly distributed in the driven shaft through hole in the circumferential direction, and a Hall sensor electrically connected with the controller is arranged on the driven shaft.

Description

technical field [0001] The invention relates to the technical field of dental equipment detection, in particular to a portable device for detecting the torque and rotational speed of dental equipment. Background technique [0002] In the field of dental equipment, some dental equipment needs to verify and calibrate the accuracy of its main parameters: actual output speed, torque and the theoretically set speed and torque of the equipment, otherwise it is easy to cause the speed and torque parameters set by the dental equipment to be different from the actual The output torque speed of the equipment is different or very different, such as: root canal preparation machine, planting machine, etc. Traditionally, there are two ways to verify the speed and torque parameters of this type of dental equipment: [0003] method one: [0004] Principle: Use a separate infrared speed tester and a separate pointer torque meter to measure the speed and torque output of dental equipment, a...

AI Technical Summary

Problems solved by technology

[0013] a: The equipment is large and inconvenient to carry;

[0014] b: The torque output of the equipment needs to be artificially fixed to the corresponding torque output value, and the human factor is too large and inaccurate;

[0015] c: The operation is too cumbersome when different output torques are required;

[0016] d: It is also impossible to judge the direction of rotation of the device
