Problems solved by technology
[0004] When the wheels are mass-produced and sampled, it is necessary to detect the residual stress shrinkage value of the sampling wheel. The current conventional residual stress detection process is: measure the 100mm positioning point, mark, tap the hit point, and measure the shrinkage value after the stress is released. This detection process It is very cumbersome, and it is very easy to produce errors when doing manual dot measurement, and it will often be reworked due to dot and measurement errors

The invention discloses a detection device for detecting residual stress of a wheel, which is characterized by comprising a positioning mechanism, a dotting mechanism, a measuring mechanism and a support frame, the positioning mechanism is arranged on the support frame, two end parts of the measuring mechanism are respectively connected to the positioning mechanism, and the dotting mechanism is arranged on the support frame; one end of the dotting mechanism is connected with the positioning mechanism, the detection device is placed on a wheel rim in parallel, and the positioning mechanism makes contact with the outer rim face of a wheel. The positioning mechanism comprises a dotting cone I and a dotting cone II, the supporting frame is arranged between the dotting cone I and the dotting cone II, and the distance between the dotting cone I and the dotting cone II is 100 mm. According to the device, the procedures of wheel two-point measurement, marking, positioning, dotting, re-detection and the like can be connected into a whole, the detection working intensity is obviously reduced, the detection efficiency and the measurement precision are improved, and the wheel residual stress process is simplified, unified and standardized. The invention further discloses a use method of the detection device for detecting the residual stress of the wheel.
Description
technical field [0001] The invention belongs to the technical field of wheel detection for railway vehicles, and in particular relates to a detection device for detecting wheel residual stress and a use method thereof. Background technique [0002] With the high-speed and heavy-duty of railway vehicles, the quality requirements of wheels are getting higher and higher, and heat treatment is the most critical quality control process in wheel manufacturing. It directly determines the operation and service of the wheel on the railway. In particular, the residual stress state inside the product has an important influence on the formation, propagation and metal spalling of wheel tread cracks that may occur during the running of the wheel. [0003] The residual stress of the wheel product is mainly formed during the quenching and tempering heat treatment process after the wheel is rolled and formed. The residual compressive stress is distributed within a certain depth range under...
