Digital display screwdriver

Abstract

The invention discloses a digital display screwdriver which comprises a rotating component, a reversing component, an electronic component, a sensor, a power source and a grip, wherein a containing space is arranged inside the grip; the reversing component, the sensor and the power source are arranged in the containing space; the rotating component is fixedly connected with the reversing component; one end of the sensor is fixedly connected with the rotating component, and the other end is connected with the grip; the electronic component is connected with the sensor; and the power source is connected with the electronic component. The operator can obtain the pretightening degree of the torque according to green, yellow or red light displayed on one indicator lamp, adjust the initial pretightening of the screwdriver on the screw and utilize the accurate measurement result displayed on the display screen to obtain the magnitude of the torque, and adjust the accurate pretightening of the screwdriver on the screw to enhance the pretension accuracy of the screwdriver on the screw, so that the pretightening performance of the screw to be tightened is better; and thus, the assembled product has the advantages of higher quality, more reliable performance, higher application safety and longer service life.

Description

technical field [0001] The invention relates to a torque tool, in particular to a digital display screwdriver for accurate measurement and fastening pretension. Background technique [0002] With the transformation of my country from a big manufacturing country to a powerful manufacturing country, enterprises pay more and more attention to the preload effect of connectors in the product assembly process, especially the precise small torque control has become a key process of quality monitoring. The torque tools used in the pre-tightening process are developing in the direction of intelligence, miniaturization, precision and ease of use, and it is more important as a torque tool for precise control of small torque and small torque. [0003] At present, the torque tools used for fastening and detecting small screws on the market in my country are mainly mechanical torque drivers, and the mechanical torque drivers adopt the principle of idling and slipping structure to achieve ...

AI Technical Summary

Problems solved by technology

[0004] When the inventor realizes fastening small screws with a mechanical torque screwdriver, he finds that the mechanical torque screwdriver has at least the following deficiencies: one is that the mechanical torque screwdriver has poor pre-tightening accuracy; the other is that the mechanical torque screwdriver has poor repeatability of tightening torque
