Returnable digital-display intelligent spanner suitable for narrow space

Abstract

The invention relates to a returnable digital-display intelligent spanner suitable for narrow space. The returnable digital-display intelligent spanner comprises a spanner main body and a torque display system arranged at the rear end of the spanner main body, wherein the spanner main body comprises a spanner head, a QH main body, a speed reducer, a QH accessory body, a sleeve, a sliding block, aspring and a handle, and the torque display system comprises a single-chip microcomputer, a torque sensor, a filter circuit, an amplifier, an analog-digital converter, a display and a power supply. According to the returnable digital-display intelligent spanner suitable for the narrow space, the torque display system can display the torque numerical value during a working state in real time through the torque display system, a remote transmission system can transmit signals to a computer terminal in real time, the real-time change of torque can be observed in a computer display screen arrangedat a long distance, so that convenience is provided for operators; and the structure is simple, intelligent control over mounting parts is realized through torque data display, and observation is simple, visual, clear and accurate.

Description

technical field [0001] The invention relates to the technical field of wrenches, in particular to a returnable digital display smart wrench suitable for narrow spaces. Background technique [0002] Used in automation and industrial applications, it is common to use a wrench to apply force to a workpiece. But for the corner, or the place where there are many front and rear obstacles and the operation is difficult, because the existing wrench is large in size, it is difficult to put it in, and the screws and nuts in different positions and directions can only be screwed in a fixed direction, which cannot be used normally. Simultaneously, in the process of using, because the size and specification of the bolt parts to be screwed are different, it is necessary to frequently replace the corresponding sleeve, which is very inconvenient to use. [0003] There are very few improvements to the use of wrenches in narrow places in the existing market, and most of them have complicated...

AI Technical Summary

Problems solved by technology

In the past intelligent torque digital display wrench, the operator can only simply read the torque value during use, and cannot store a large amount of reasonable torque value of a certain bolt fastener. Therefore, it is necessary to use a torque value signal that can It is a technology for long-distance transmission, and can record the data at long-distance places for the operator to save
