Description

Torque wrench

This creation is about a torque wrench. In detail, it is a wrench tool that integrates both mechanical and digital torque measurement mechanisms for the operator to choose or use.

According to the technical field of mechanical assembly, bolts and nuts are used to lock various components, which is a relatively well-known fixing method. However, because each person's feeling of strength is not the same, and some special combinations are not as tight as possible, so there is a torque wrench to ask the market, so that every screw lock operation, even in different people Under the operation, the same torque requirement can also be achieved; however, the torque wrench has a pure mechanical design. When the user applies a force close to the preset torque value, the torque wrench will generate a swinging feel. The user is reminded that there is also an electronic torque wrench with a display module for the user to obtain information about the torque value through the display module.

With the advancement of science and technology, the digital torque wrench has the advantages of easy use and convenient interpretation. It has gradually replaced the mechanical torque wrench in the market. It is the wrench tool preferred by the operators; however, the mechanical torque wrench is not operated. It is convenient to have a digital torque wrench, but it is not without merit. The mechanical torque wrench has the advantages of being difficult to malfunction and without the need of electric power support. In addition, the digital torque wrench detects the shape of the rod with a strain gauge. It becomes the analysis torque data, and the mechanical torque wrench is based on the rod body tripping as the torque value. The technology applied by the two is inherently different, so there is no torque wrench integrated in the market for both digital and mechanical.

In view of this, the creator has been engaged in the development of related industries for many years, and has in-depth discussions on the problems faced by the existing torque wrenches, and actively seeks solutions. After long-term research and development, he has succeeded in creating a kind of success. A wrench tool that integrates both mechanical and digital torque measurement mechanisms for the operator to choose or use.

This creation is about a torque wrench, a wrench tool that integrates both mechanical and digital torque measurement mechanisms for the operator to choose or use.

In order to achieve the above-mentioned creative purpose, the "torque wrench" of the present invention includes a main body member, a handle bar member, a working head member and an inner member. The inner surface of the main body member is an accommodation space. The main body member is provided with a spring in the accommodating space, and the shank member is screwed on one end of the main body member and is pushed against the spring. The inner rod member is disposed in the accommodating space, and one end is subjected to the spring normal bomb. One end of the working head member is inserted at the other end of the main body member, and a tripping mechanism is coupled between the working head member and the inner member, and the working head member is inserted into the main body member. A torque sensing unit is disposed on each side of the body, and a digital processing unit of the torque display is disposed on the surface of the main body member, and the digital processing unit is electrically connected to the torsion sensing unit; the main body member is pivoted a shaft for yaw rotation of the working head member, and a positioning rod for assembling and disassembling to limit the yaw rotation of the working head member; thus, when the positioning rod is inserted into the main body member, the working head The rod is simultaneously subjected to the shaft and LEVER restricted from swinging, when the working operation of the wrench head obtained easily shaped lever Change, the supply of the variable gauge to detect the torque data to achieve the detection effect of the digital torque wrench; and when the positioning rod is separated from the main body member, the working head member is only pivoted with the shaft and can be swung Continued rotation of the grip member to adjust the torque threshold value by the spring pressing trip mechanism. When the wrench is turned to the previously set torque threshold, the trip mechanism can be actuated to make the working head member yaw warning. In order to achieve the detection effect of the mechanical torque wrench.

According to the above-mentioned creations, the "torque wrench" of this creation has the application features of a digital torque wrench and a mechanical torque wrench, which provides the operator with the advantages of easy operation and interpretation of data when using digital torque detection. It can also be switched to mechanical torque detection according to requirements, so as to obtain the advantages of being difficult to malfunction and without the need of electric power support; therefore, the novel can be said to be a practical and progressive creation, which is worthy of promotion by the industry. And publicized to the public.

This creation is about a torque wrench, which is a wrench tool that integrates both mechanical and digital torque measurement mechanisms for the operator to choose or use. Please refer to the first to third figures. To achieve the foregoing creative purpose, the novel "torque wrench" includes a main body member 1, a grip member 2, a working head member 3 and an inner rod member 4; the inner surface of the main body member 1 is a Accommodating space 11, the main body member 1 is accommodated The space 11 is provided with a spring 12, which is screwed to one end of the main body member 1 and is pushed against the spring 12. The inner rod 4 is disposed in the accommodating space 11 and is supported by a spring at one end. 12 is normally bounced; one end of the working head member 3 is inserted at the other end of the main body member 1, and a tripping mechanism 5 is coupled between the working head member 3 and the inner member 4, and the working head The part 3 is inserted into the main body member 1 and has a torque sensing unit 6 disposed on each side of the main body member 1. The surface of the main body member 1 is provided with a digital processing unit 7 with a torque display, and the digital processing unit 7 is coupled to The torque sensing unit 6 is electrically connected; the main body member 1 is pivotally provided with a shaft 13 for yaw rotation of the working head member 3, and an assembly and disassembly is provided to limit the positioning of the yaw rotation of the working head member 3. The rod 14; thus, when the positioning rod 14 is inserted into the main body member 1, the working head member 3 is restricted by the shaft 13 and the positioning rod 14 at the same time and cannot swing, and the operating wrench is used to make the working head member 3 Easy to deform, supply torque gauge to detect torque data, to achieve the detection effect of digital torque wrench (As in the state of use of the second figure); when the positioning rod 14 is separated from the main body member 1, the working head member 3 is pivoted only with the shaft 13 to be swung, and the grip member 2 is continuously rotated. The spring 12 presses the tripping mechanism 5 to adjust the threshold value of the torque threshold. At this time, when the wrench is turned to the previously set torque threshold value, the tripping mechanism 5 can be actuated to make the working head member 3 yaw warning to reach the machine.
