Description

Torque wrench

The present invention relates to the technical field of hand tool equipment, and more particularly to a hand tool for a torque wrench.

There are many types of hand tools for loosening or locking the screw, such as plum torque wrench, socket wrench, ratchet wrench or open wrench. The structure of the wrench generally has a screw and a screw at the front end of the handle. The head of the card is used to pull the screwed workpiece, thereby applying a torque to the handle to generate a torque to drive the head to screw the screw into the object to achieve the effect of tightening or unscrewing, and the screw is screwed The firmware is assembled and combined with components of various industries, and the objects can be repeatedly disassembled after being combined, so it can be applied to various sizes of applications.

In general, industrial finished products need to use various types of screws due to structural differences, and are assembled and fixed by different strength and strength according to different load requirements. For heavy industries such as aerospace, shipbuilding and vehicles, their components must be assembled with a certain amount of torque to achieve a solid structure, withstand the impact of air pressure and power; while precision industries such as electromechanical, their components cannot be assembled with excessive torque. In order to ensure that it can operate accurately. However, no matter what kind of industrial finished product, less than one point of torque or more than one point of torque when combined with the screw is likely to cause the structure and the screw to lose its utility or damage.

That is, when the tightness of the screw is insufficient, the effect of screwing the two objects cannot be achieved, and the looseness is easy to loosen; otherwise, when the tightness of the screw is too high, the screw is prone to chipping and the object is easily damaged. Deformation, even a situation that cannot be disassembled. Especially in precision equipment or small instruments, because the structure is easy to be damaged by inadvertent force, it requires more precision than the general object, and the wrench tool is the key to controlling the torque.

The biggest problem faced by the wrench tool in operation and use is that it is difficult for the user to pinch the tightness of the screw to be tightened. The conventional wrench tool does not have a twisting force measuring device, and the hand tool cannot be accurately measured. The torque and tightness of the screw are made, so the user cannot confirm whether the tightness of the screw being operated is moderate. However, if the user cannot know the tightness, it can only judge according to the existing experience, that is, according to the screw-solid torque specification of various implements, so it will be like "lock to the bottom and then rotate." A 1/4 turn can be a code of practice; this kind of screw-tight torque that can't be too loose or too tight is to prevent the thread from being damaged by excessive torque, but it is difficult to accurately control with traditional wrench tools. Screw-solid torque of the screw. In view of this, the industry has introduced a wrench tool with a twisting force measurement function.

For example, the "freewheeling torque wrench" patent of the Republic of China Announcement No. M552410, which is described in the first paragraph of the patent application: "1. A free-running torque wrench comprising a tubular body, one end of the tubular body A drive head is provided, and the other end of the pipe body is provided with a grip, wherein the drive head has a head, the head is provided with a receiving groove along the radial direction of the pipe body, and along the pipe The axial direction of the body is provided with a communication hole connecting the receiving groove and the pipe body, and a ratchet member rotatable relative to the driving head is disposed in the receiving groove, and an abutting unit is disposed at the connecting hole. At the same time, the tube body is provided with an elastic unit for elastically pushing against the abutting unit to abut the ratchet member. The main feature of the driving head is that the head of the driving head is further provided with a lateral communication between the communicating holes. Pressing the hole; the abutting unit has a fixing seat, and the fixing seat is provided with a sliding hole. A sliding member is disposed in the sliding hole, and the guiding seat is disposed adjacent to a side of the grip body with a guiding seat, and the guiding side of the guiding seat is provided with a guiding inclined surface corresponding to the pressing hole. The guiding inclined surface is climbed toward the driving head by the grip, and the guiding seat further has a guiding hole disposed along the axial direction of the tubular body, and a slidable abutting member is disposed in the guiding hole. One end of the abutting member abuts against the rolling member, and the other end of the abutting member is pushed by the elastic unit; a pressing member is locked to the pressing hole when the pressing member is locked When one end of the pressing member abuts against the guiding inclined surface, the wedge-shaped action between the transmitting and the guiding inclined surface pushes the guiding seat to move toward the fixing seat to press the fixing seat and the guiding seat . "."

In the above, the patented torque wrench has a ratchet member which is rotatable relative to the driving head in the groove of the driving head, and is connected to the screw by the protruding one-type driving portion and is tightened with the sleeve. The loosening operation; however, the screw for various equipments has various tightness requirements depending on the requirements of different uses. Some fasteners may require more tightness than the manual load (because some screws are locked by pneumatic machines) Tightly), that is, the use of a torque wrench and a sleeve to tighten the screw firmware, it may be impossible to remove the manpower limit.

Although, some torque wrenches will design the handle as a multi-section telescopic combination to extend the length of the operation and the driving arm to amplify the driving torque; however, the multi-section combination of the handles is generally a hollow structure. However, its structural strength may not support the operation of the human limit and may be bent.

Therefore, how to improve the creator for the disadvantages of the multi-section combined shank structure strength, the inability to support the human limit operation, and the ease of bending The difficulty points that the case is intended to solve.

The main purpose of this creation is to connect the different types of driving heads of the torque wrench and the different kinds of screws through the two ends of the creation, thereby connecting the length of the extended operation with the driving force arm and the driving torque of the amplification, and can smoothly Different types of tightening requirements of the screw firmware for assembly torque measurement and precision assembly of accurate torque, can form the best assembly quality of the combined structure, with better use of progress.

In order to achieve the above purpose and effect, the creation of the torque wrench of the torque wrench is used to connect the screw and the torque wrench, and the torque wrench is assembled and twisted for the screw firmware and the accurate torque assembly, including: a tool body, the tool The driving body has a driving end and a connecting end, and the driving end has a driving portion for engaging and coupling with the screw. The connecting end is embedded with a set of the connecting portions, and the assembling portion has two protrusions protruding from the two sides of the connecting end. The set end, and a set of holes penetrating through the set end of the two sets, each set end or set hole is provided in combination with a torque wrench.
