Embodiment 1

[0075] figure 1 It is a schematic diagram of the torque tool device of Example 1 of the present invention. The torque tool device of this embodiment is composed of a torque wrench 1 as a torque tool and a tightening information processing terminal (hereinafter referred to as a processing terminal) 20 . figure 2 is the structure diagram of torque wrench 1, image 3 is the circuit diagram of torque wrench 1, Figure 4 is a circuit diagram of the processing terminal 20 .

[0076] exist figure 1 In the torque tool device of Example 1 shown, when tightening a fastening member such as a bolt (hereinafter, a bolt is used as an example) is tightened by the torque wrench 1, information including the measured torque value at the time of completion of the tightening is transmitted. to the processing terminal 20. The processing terminal 20 receives information including the measured torque value, and performs a pass / fail judgment on whether the measured torque value is a preset to...

Embodiment 2

[0127] A traceable torque tool device according to Embodiment 2 of the present invention will be described based on the drawings.

[0128] In Embodiment 1, when the tightening data is transmitted and received between the torque wrench 1 and the processing terminal 20 , an in-company management number that can be arbitrarily set by the user is transmitted and received as the identification number of the torque wrench 1 . On the other hand, Example 2 differs from Example 1 in that a serial number unique to each torque wrench is used as the identification number of the torque wrench 1 .

[0129] Regarding other parts, the torque tool device of embodiment 2 is the same as that of embodiment 1 figure 1 , figure 2 , image 3 , Figure 4 The structure of the torque tool device shown is the same. Therefore, regarding the torque tool device of the second embodiment, the description of the parts common to the first embodiment will be omitted.

Abstract

A torque tool device can quickly perform tightening work without requiring operation other than the tightening and can perform continuous tightening by instantaneously determining whether tightening has been appropriately performed. The torque tool device has a torque tool (1) for measuring a torque value by which a bolt or any other fastener is tightened and capable of transmitting the measured torque value by wireless communication means, and also has an information processing terminal (20) having information processing means that receives the measured torque value and determines whether the torque value is appropriate. It is not necessary to provide the torque tool (1) with a device for a pass/fail determination, and this helps to reduce the weight of the torque tool device. Further, because the ISM frequency band is used for the wireless communication, instantaneous transmission and reception of determination results are possible to allow the torque tool (1) to perform continuous and quick tightening work.

Description

technical field [0001] The present invention relates to a torque tool device, which includes: a torque wrench and other torque tools for tightening fastening parts such as bolts and nuts; In the information processing terminal, the torque tool and the fastening information processing terminal perform two-way wireless communication, and can quickly report to the operator whether the fastening of the connecting member is properly performed. [0002] In addition, fastening data such as measured torque values ​​of fastening parts such as bolts are sent to the processing terminal through wireless communication together with the serial numbers of torque tools such as torque wrenches, so that tightening data can be managed for each torque tool serial number, Identifying data on connected components such as bolts that have been tightened enables traceability from torque tools to torque standards. Background technique [0003] Conventionally, with regard to torque tools such as torq...
