Problems solved by technology

[0004] However, the above-mentioned digital torque wrench does not have the function of reminding the torque value. Since the angle of use and the posture of use are not fixed when using the digital torque wrench, it is inconvenient to observe the torque value displayed on the digital display with the naked eye, which is easy to be caused by the operation. Inadvertently causing damage to the screw lock components or screw holes, which in turn affects the operation function and precision of the machine itself, and the compatibility of the use scene is poor. This problem needs to be solved.

Embodiment 1

[0048] A digital display torque wrench, refer to figure 1 , which includes a wrenching part 1 , a handle 2 and a connecting rod 3 , and the connecting rod 3 is connected between the wrenching part 1 and the handle 2 . When in use, after the operator holds the handle 2, the bolt, screw, nut or other components can be turned by the pulling part 1 .

[0049] refer to figure 1 and figure 2 , The wrenching part 1 is provided with a torque sensor 4, and the torque sensor 4 is used to detect the torque value when the operator twists the component through the digital torque wrench. The grip 2 is provided with a digital display module 5, a key module 7 and an indication module 8, the digital display module 5 is used to display the torque value detected by the torque sensor 4, the key module 7 is used to set the target torque value, and the indication module 8 is used to Send an alarm signal. A main control board is arranged in the handle 2, and the main control board is connected ...

Embodiment 2

[0064] A kind of operation method of the digital display torque wrench based on the digital display torque wrench in embodiment 1, refer to figure 1 and figure 2 ,include:

[0065] For unit selection, the user presses the first button 71 and then releases it to start the digital display torque wrench; when the digital display torque wrench is started, the user short presses the second button 72 to switch the unit of the torque value displayed by the digital display module 5, In this embodiment, the torque value units include N.m (Newton.meter), in.lb (inch.pound), ft.lb (foot.pound) and kgf.m (kilogram force.meter);

[0066] Set the target torque value, when the digital display torque wrench starts, the user presses the third button 73 to decrease the target torque value, or the user presses the fourth button 74 to increase the target torque value;

[0067] Mode selection, when the digital display torque wrench starts, the user presses the second button 72 for a long time; ...

Abstract

The invention discloses a digital display torque wrench and an operation method thereof, and relates to the technical field of torque wrenches. The digital display torque wrench aims to solve the problems that an existing digital display torque wrench has poor compatibility in use scenes and is not conducive to accurate operation. According to the key points of the technical scheme, a torque sensor is arranged on a pulling part, a main control board is arranged in a handle, and a key module, a digital display module and an indicator module which are connected with the main control board are arranged on the handle; the indicator module comprises a first indicator lamp and a plurality of second indicator lamps, and the main control board is used for controlling the second indicator lamps tolight up sequentially according to the increase of the torque value detected by the torque sensor before the torque value detected by the torque sensor reaches a set target torque value; and the maincontrol board is further used for controlling the first indicator lamp to light up when the torque value detected by the torque sensor reaches the set target torque value, and the digital display torque wrench has the advantages of good compatibility in use scenes and high operation accuracy.

Description

technical field [0001] The invention relates to the technical field of torque wrench, more specifically, it relates to a digital display torque wrench and its operating method. Background technique [0002] A wrench is a commonly used installation and removal tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts, and other openings or casings that are threaded to hold bolts or nuts. In some high-precision machinery, there are certain procedures and requirements for appropriate torque operation for the removal of each screw lock component. If the operation is not careful, it may cause damage to the screw lock component or screw holes, or damage the operation function of the machine itself. Precision, but the existing hand tools cannot display the torque in real time during force operation, therefore, it is impossible for the user to understand the actual force torque value. Considering the above situation, it is necessary to design a digita...
