Description

Swing type torsion sensing and transmitting device

Technical Field

The present invention relates to a swing type torque force sensing and transmitting device, and more particularly to a device between a handle and various head sets of a head-exchanging torque wrench for sensing and transmitting locking torque force and angular displacement, thereby increasing the flexibility in use.

Background

The known digital display torque wrench mainly utilizes the characteristic that the strain gauge can generate resistance value change when being stressed to deform to measure the torque generated by the wrench so as to control and judge the locking torque of the spiral fastener by a user.

However, the digital display type torque wrench has high production cost, and the rotating head set is not replaceable in a fixed type, so that if a user needs to perform different types of locking operation, the user needs to purchase other types of hand tools with measured torque values, and the burden is increased. Therefore, the torque wrench of the replaceable head set has the advantages that a user can use the same handle to replace various types of head sets in a matching way according to the requirement of locking operation, and the design of digital torque sensing and displaying is also made on the handle of the torque wrench of the replaceable head set. However, the handle of each torsion wrench with replaceable head sets can only be used with a head set with a consistent 'combination structure', and still costs a lot.

Because of the wide variety of the type of the replaceable head set torque wrench in the market, the combination of the head set and the handle is high in price, and further, in the trend of industry 4.0 and industry internet of things, more and more manual torque wrench locking operations are required to record the applied torque data, so the wrench with the digital torque display function seems to be the only choice.

The conventional torque sensing and transmitting device is usually a rotary torque sensor (Rotary Torque Transducer) built in the tool body or externally hung on the output end of the tool, and is configured to detect the deformation of the spindle caused by the force, or to attach and fix the sensing components such as strain gauges to the fixed position of the torque tool handle, and to calculate the torque by detecting the deformation of the spindle caused by the force or the pulling force, and to calculate the angular displacement by using a gyroscope.

Various commercially available digital display type torque wrench with replaceable head set can only be used for the head set with the consistent type and size of the handle output end combination structure.

Various known digital display type wrenches or replaceable head group type torque wrenches with digital display function are used to fix the torque sensor assembly device on the handle.

The torque wrench with replaceable head set refers to various torque tools for locking or releasing screw fasteners (bolts or nuts) by manual swing force application, such as dial type, pointer type, fine adjustment type or sound type conventional torque wrench or digital display type torque wrench, which uses the same handle and replaces the head set with the same type but different type according to the requirement of locking operation.

The common combined structure of the torsion wrench with the replaceable head group is a dovetail type, a round type, a rectangular type and other special types, and is manufactured by adopting a male-female embedded structure, and the combined structure is provided with a positioning and orientation mechanism, so that the assembly is convenient for aligning the buckling connection and the force application direction.

Furthermore, after the torque force sensing devices are replaced by different head sets, the calculated torque force and angle value result are different due to the fact that the distances between the torque force sensing components attached and fixed on the tool handle and the rotation center of the bolt or the nut driven by the replaced head set are different. Before the use, operators need to check the torsion meter and the angle gauge respectively to obtain corresponding values, and the operation is tedious and time-consuming.

Disclosure of Invention

In view of the problems of the prior art, the present invention provides a swing type torque sensing and transmitting device, which is modularized, so that in a certain torque sensing interval, only through sensing the material and size change of the main shaft and the combination structure of the output end and the input end of the main shaft, the handle and the selected head group can be connected in a pluggable manner, so that the torque wrench of all the replaceable head groups is converted into a wrench with the torque sensing and displaying function, thereby facilitating the user to expand the types of the selected head groups through the swing type torque sensing and transmitting device, further increasing the flexibility and convenience in use, and greatly improving the quality of assembly operation.

The swing type torsion sensing and transmitting device of the invention calculates the applied torsion by sensing the linear relation between the deformation sensing value generated by the bending of the main shaft and the generated torsion value within the yield strength (yield strength) range.

The device of the invention can be used for manufacturing male-female switching mechanisms with the same size or different types by sensing the combined structures at the two ends of the main shaft, so that the swing type torsion sensing and transmitting device is inserted and pulled between handles and head groups with different combined structures, thereby increasing the elasticity in use.

The device of the invention can be inserted and plugged between the handles and the head groups of the same or even different torque tools with the same combined structure so as to increase the flexibility in use.

The device is suitable for the head group of various brands sold in the market, and the input end of the device is of a combined structure with various types of designs, such as steering designs of inner hexagons, polygonal edges, openings, square rods and the like.

The device of the invention can further manufacture the two ends of the sensing main shaft into the clamping mechanisms so as to facilitate the insertion and the extraction of the head group switching devices with various types and sizes, and the device is further combined between handles or head groups with various different combination structures so as to increase the elasticity in use.

In view of the above, the present inventors devised a swing type torque sensor and transmitter, which can be installed between the handle and the head set of any brand-name torque wrench with a replaceable head set, so as to increase the flexibility in use, and convert the torque wrench into a torque wrench with equivalent other digital torque sensor display functions. In addition, the device of the invention can further enable the combined structure of one handle to be matched with the head groups of other combined structures by sensing the type and the size changes of the input end and the output end of the main shaft. In addition, the device can effectively reduce the inventory variety and the production cost through modularization, thereby greatly improving the convenience in locking operation. In addition, the device can be used for a user to input or scan the codes of the matched tool handle and head set, and the torque force and the angle are checked in advance before the device is used, so that when the device is convenient for an operator to operate, the operation parameters of the tool handle and head set combination can be obtained only by inputting the relevant codes, and the operation is performed. The device can provide a wired or wireless data transmission access mode, thereby improving the industrial practicability.
