Technical Field

[0001] The invention belongs to the field of engineering machinery detection equipment, and in particular relates to a detection method and system for a double-wheel milling cutter head. Background Art

[0002] The double-wheel milling cutter head is an important component of the double-wheel milling product and an important working mechanism. The size of the double-wheel milling cutter head directly affects the working efficiency of the double-wheel milling. However, the double-wheel milling cutter head is composed of a series of milling cutter heads, and it is difficult to directly detect the double-wheel milling cutter head in terms of spatial size.

[0003] In the actual double-wheel milling cutter head inspection, the traditional method of using the inspection tool to directly measure, there are problems including: 1. The double-wheel milling cutter head is composed of a series of milling cutter heads, and the spatial layout is complex, which is not easy to detect directly; after the detection, the detection results are not accurate and the error is large, which cannot truly reflect the manufacturing level.

[0004] 2. There are a large number of double-wheel milling cutter heads. If traditional methods are used for fine inspection, it will take a long time to inspect each milling cutter head. In actual applications, the product models of double-wheel milling cutter heads are different, and the number of heads is different, which makes the traditional inspection method time-consuming.

[0005] 3. Although the appearance inspection method can be used to shorten the inspection time and detect obvious defects on the appearance of the milling cutter, it is impossible to perform high-precision and in-depth inspection on the double-wheel milling cutter head. Therefore, the existing inspection results cannot truly reflect whether the finished double-wheel milling cutter meets the design requirements, resulting in a low pass rate for double-wheel milling cutter heads.

The detection system for a double-wheel milling cutter head according to claim 7, characterized in that: The detection unit comprises: Linear module, installed at the end of the lifting rail; The servo motor is installed at one end of the linear module and is electrically connected to the PLC controller through a cable; The displacement distance measuring sensor is installed on the moving seat of the linear module with the detection end facing the double-wheel milling cutter head. At the same time, the displacement distance measuring sensor communicates with the PLC controller to provide real-time feedback of the displacement signal of the detection unit and the distance between the detection unit and the double-wheel milling cutter head. The power output by the servo motor enables the moving seat to move horizontally along the linear module, thereby adjusting the distance between the displacement ranging sensor and the double-wheel milling cutter head.
