A kind of socket wrench torsion control method and manual socket wrench intelligent conversion joint

Abstract

The invention discloses a socket wrench torque control method and a manual socket wrench intelligent conversion joint. A socket wrench application torque, rotation angle monitoring and control method, the controller realizes the operation of torque application torque and rotation angle detection, control and calibration in various modes according to the network environment of the job site, including: no network when there is no network The normal torque and rotation angle monitoring control mode; the networking mode when there is a network, including the torque and rotation angle calibration mode; the networking mode when there is a network, and the torque monitoring and control mode that operates according to the torque method; the networking mode when there is a network , also includes the torque and rotation angle monitoring control mode operating according to the torque-angle method. Under the network environment, according to the command of the host computer, it can enter the torque method or torque-angle method control mode or the torque and angle calibration mode, and perform real-time torque and angle digital display, light instructions and voice prompts during the operation process, which improves the thread auxiliary operation. quality and operational efficiency.

Description

technical field [0001] The invention relates to a method for controlling torque and rotation angle of a socket wrench. A socket wrench or a conversion joint capable of monitoring the torque and rotation angle is used to realize the detection and control of the torque and rotation angle during the torsion process of the socket wrench. Background technique [0002] The thread pair connection is widely used in various mechanical structures, and is the most commonly used connection method at present. Its essence is to reliably connect two or more components together by controlling the axial pretightening force (clamping force) to an appropriate range. The axial pretightening force is an important indicator for evaluating the reliability of the screw pair connection. Since the axial pretightening force is an internal force, it is currently impossible to directly control the pretightening force to assemble threaded connections. The commonly used control methods include torque meth...

Problems solved by technology

Its disadvantages are: high price, complex control system, not portable, etc.

The digital torque wrench is to install a strain gauge force sensor at the sensitive position of the force point on the wrench rod. The torque will be displayed on the LCD screen in real time through the digital operation of the electronic detection technology, and the peak value of the torque can be displayed and saved. The accuracy is high. Its disadvantages are : Torque cannot be monitored online, rotation angle detection and control cannot be performed, and there is a twisted thread pair that is not on the same central axis as the torque detection. The force application position, force direction and torque stability are greatly affected by human factors, and it is difficult to guarantee Twist quality

Its disadvantages are that one type of sleeve can only be used to torque one type of nut / bolt, the cost of use is high, and there is no angular velocity detection and control, light indication and sound prompt function during the torqueing process, and the accuracy of the torque during the torqueing process Difficult to guarantee

[0006] A socket wrench conversion joint is often used in thread pair torsion operations. The upper driving square hole is connected to the square tenon on the torsion plate rod, and the lower square tenon is connected to the square hole of the standard sleeve for changing The size of the square hole and square tenon is suitable for twisting different thread pairs. At present, there is no socket wrench smart conversion joint that can monitor the torque and angle. It is used for torque and angle monitoring of manual wrenches.
