Problems solved by technology

However, the sensor is directly attached to the rotating component, and it is very easy to generate centrifugal force due to high-speed rotation, and the adhesive is aged and degummed, and the sensor is peeled off and loses its function. This is a shortcoming.

Embodiment Construction

[0028] The invention improves on the defect that the traditional locking tool cannot measure and control the torsion force. The design of the present invention can be applied to locking tools such as pneumatic, electric or manual, as shown in the accompanying drawings. One end of the torque sensor connector is connected to the tool used to lock the screw and nut, such as a torque wrench, screwdriver, etc., and the other end is set on the sleeve to lock the screw or nut. When locked by this design, that is The locking torque can be detected and controlled at the set torque value. The present invention is mainly based on the rib structure, such as image 3 , Figure 4 So, the torque sensor includes a shell designed with a rib structure, a set of strain gauges, a set of amplifiers, a power supply, a set of logic operators, a set of input devices, a set of memory modules and a set of transmission modules Group 1. Anti-vibration glue injection material, filled and fixed with ant...

Abstract

A torque sensing and control device for tools comprises: a torque sensing and transmitting adapter fabricated with rib structure and mounted on or built in a fastening tool; at least a torque sensor secured on at least a rib evenly spaced and formed on the adapter and operatively sensing a torque signal when applying a torque on a work or object when rotatably operating the fastening tool; and a digital display control module operatively receiving the torque signal, displaying a torque data and generating an audio or visual warning signal for reminding the user for stopping operation of the fastening tool, or for switching off power or air supply to the fastening tool, and or actuating a delay control to restart a next fastening operation in a pre-determined time interval.

Description

technical field [0001] The invention relates to a tool torque sensing and control device with anti-vibration function. Background technique [0002] Most of the traditional screw or nut locking tools cannot let the user know the degree of locking of the screw / nut (the amount of torque that can be withstand), if the torque force of the screw / nut locking is insufficient, the workpiece will be damaged due to There is a risk of loosening due to vibration; if the screw / nut is locked too tightly, exceeding the torsion (mechanical yield strength) that the screw / nut can withstand, it will cause permanent damage to the screw / nut. On the other hand, the workpiece is in use There is also the danger of instant damage. [0003] The existing torque sensor such as US 7,307,517 discloses a wireless torque sensor, which is attached to a rotating component, thereby generating a torque signal and measuring the result. However, the sensor is directly attached to the rotating component, and it...
