[0030] For the first embodiment, please refer to Figure 1 , Figure 1 The present invention provides a schematic diagram of the structure of a wheel profile feature acquisition circuit, wherein the circuit system includes a feature acquisition unit and a control unit. The control unit can send a control signal to the feature acquisition unit to configure and control the wheel profile feature acquisition process, and the feature acquisition unit can also send the acquired wheel profile features to the control unit, and the subsequent control unit can also perform data processing on the wheel profile features.

[0031] For details, please refer to Figure 2 , Figure 2 The present invention provides a circuit diagram of a wheel profile feature acquisition circuit.

[0032] The feature acquisition unit includes a switching power supply 1 for powering the feature acquisition unit, a feature acquisition module 2 for acquiring wheel profile features, and a square wave generator 4 for sending a control signal to the feature acquisition module 2; the switching power supply 1, the feature acquisition module 2 and the square wave generator 4 form a working circuit through a data line, and the feature acquisition module 2 and the square wave generator 4 are connected in parallel.

[0033] The switching power supply 1 is a 24V DC voltage source, which powers various electronic devices in the feature acquisition unit. In addition, the switching power supply 1 can be a mobile power supply, and the switching power supply 1 can be powered by a 220V voltage.

[0034] The feature acquisition module 2 includes a laser control submodule 2-1 and a laser probe 2-2 for acquiring wheel profile features. The laser control submodule 2-1 and the laser probe 2-2 are connected via a data line.

[0035] For example, the feature acquisition module 2 may be composed of a laser displacement sensor. The feature acquisition module 2 is mounted on a tool holder for processing a wheel. The laser probe 2 - 2 in the feature acquisition module 2 is aligned with the wheel profile to be detected.

[0036] The control unit includes an electronic device 5 and an industrial computer 6 for controlling the working state of the lathe. The electronic device 5 and the industrial computer 6 are connected via a communication cable, and the laser control submodule 2-1 and the electronic device 5 are connected via a communication cable.

[0037] Specifically, the staff can set the collection mode and collection parameters through the industrial computer, and at the same time, the staff sends a square wave signal to the feature collection module 2 through the square wave generator 4. After receiving the square wave signal, the feature collection module 2 starts to collect the wheel profile features. The laser probe 2-2 sends the collected wheel profile features to the laser control submodule 2-1, and then the laser control submodule 2-1 sends it to the electronic device 9. The electronic device 9 processes the wheel profile features and sends the output results to the industrial computer 6, where the output results include the measured wheel type, measurement data, compensation amount, etc. The industrial computer 6 can determine the difference between the actual wheel profile and the theoretical wheel profile through the compensation amount, and the actual wheel profile can be determined based on the difference value, and then the wheel processing parameters are adjusted based on the actual profile, thereby improving the processing quality while protecting the tool.
