Description

Technical Field

[0001] The utility model relates to the technical field of torque wrenches, in particular to a torque wrench detection mechanism. Background Art

[0002] A torque wrench is a type of wrench. When tightening threaded fasteners such as screws, bolts, and nuts, it is necessary to control the torque applied to ensure that the threads are tightened and not damaged due to excessive torque. Therefore, a torque wrench is used for operation. Torque wrenches generally need to be tested and calibrated before use.

[0003] The existing torque wrench is fixed and clamped only by fastening bolts and a second bracket, which lacks stability of the torque wrench, further reduces the calibration and detection of the torque wrench by the equipment, reduces the practicality of the equipment, and is not conducive to actual application and operation.

[0004] A Chinese patent discloses a torque wrench measurement and calibration device (authorization announcement number CN219265581U). This patented technology manually rotates a fixing assembly to clamp and fix the torque wrench, then drives the calibration assembly through a drive transmission assembly to calibrate and test the torque wrench. Simultaneously, manually turning the fixing assembly rotates the auxiliary assembly. This prevents the support plate from tilting during downward movement of the fixing assembly, which could cause the torque wrench to tilt. This improves the stability of the torque wrench on the support plate, further enhances the calibration and testing of the torque wrench, and increases the practicality of the device, facilitating practical application and operation.

[0005] However, it has certain disadvantages: the spacing between its adapter and the third U-shaped plate will be fixed, which means that the device can only be used for torque wrenches within a specific length range. For torque wrenches with lengths exceeding or less than this range, they either cannot be effectively clamped or the torque sensor cannot accurately connect to the torque end of the torque wrench. This reduces the versatility and flexibility of the device, and it is necessary to replace devices of different specifications to adapt to torque wrenches of different lengths. Utility Model Content

[0027] exist Figure 1 、 Figure 3 and Figure 4 Middle: The upper surface of the testing platform 1 is located on the right side of the support base 3 and is provided with an adjustment mechanism 14. The adjustment mechanism 14 includes a tooth plate 15. A fixed rod 16 is fixedly connected to the center position of the left surface of the tooth plate 15.
