[0002] Currently, professional instruments and equipment are mostly used to detect the breaking torque of shafts with a diameter of ≤10mm. By applying a rotational torque to the shaft until the shaft breaks, the maximum value is recorded to obtain the breaking torque of the shaft. The disadvantage is that the procurement and commissioning of equipment is time-consuming and expensive, and a dedicated site is required. Therefore, it is necessary to develop a detection device with a short procurement and processing time to meet production requirements. Summary of the Invention

[0003] The utility model provides a shaft damage torque detection device to solve the problems of long time and high cost in purchasing and debugging equipment and the need for a special site when using professional instruments and equipment to perform shaft damage torque detection.

[0004] The technical solution adopted by the utility model is to include a torque wrench, an adapter, a screw, an upper clamp, a shaft, a vise and a lower clamp, wherein the upper clamp and the lower clamp clamp the detection part of the shaft, and the upper clamp and the lower clamp are fixed together with screws, the root of the shaft is clamped and fixed with a vise, the adapter is sleeved on the outside of the upper clamp and the lower clamp, and the wrench head of the torque wrench is sleeved on the convex head of the adapter.

[0005] The wrench head of the torque wrench is in the shape of an inner hexagon.

[0006] The torque wrench has a numerical display.

[0007] The convex head of the adapter is in an external hexagonal shape.

[0008] The inner hole of the adapter is square.

[0009] The upper fixture, the lower fixture and the shaft detection portion form an interference fit.

[0010] The utility model has the advantages of novel structure, adopts pliers to clamp the root of the shaft, uses a fixture to clamp the detection part of the shaft, uses an adapter to connect the fixture, uses a torque wrench with a numerical display to connect the fixture, and rotates the torque wrench until the shaft breaks, and records the maximum value to obtain the destructive torque of the shaft. The torque wrench and pliers used can be purchased from the Internet or physical stores, and the procurement time is short. The processing time of the fixture and adapter is short. It can be applied to the detection test of the destructive torque of all shafts with a diameter of ≤10mm, does not require a special site, reduces the test cost, and meets the production requirements.
