[0014] In order to more clearly illustrate the specific embodiments of the present invention, the following briefly introduces the drawings required for use in the specific embodiments. In all the drawings, each element or part is not necessarily drawn according to the actual scale.

[0015] Figure 1 This is a flow chart of a method for machining an automobile engine valve provided by one embodiment of the present invention. DETAILED DESCRIPTION

[0016] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0017] like Figure 1 The flowchart of the automobile engine valve processing method shown in FIG. 1 includes: Step 1: Control the conveying device to convey the valve material to the rough processing device, and perform rough processing on the valve material by the rough processing device to obtain a rough processing component; Step 2: transferring the rough-machined component to a preliminary quenching device, and performing preliminary quenching on the rough-machined component by the preliminary quenching device; Step 3: Cutting a conical surface on the rough-machined component that has been preliminarily quenched by a CNC lathe to obtain a fine-machined component; Step 4: Perform secondary quenching on the finished components using a quenching machine; Step 5: Grinding the finished components after secondary quenching by fine grinding equipment; Step 6: Polish the polished finished component with a polishing machine to obtain the automobile engine valve.

[0018] Specifically, the equipment used to process automobile engine valves includes roughing equipment, preliminary quenching equipment, CNC machine tools, quenching machines, fine grinding equipment, and polishing machines. Conveyors are installed between these machines to transport valve materials or processed components to the next stage of equipment.

[0019] First, the valve material is conveyed to a rough machining facility via a conveyor. Rough machining equipment, such as a cylindrical grinder, sequentially machines the stem outer diameter, disc outer diameter, and disc taper. The transitions between each machining step are determined by the program's programmed processing time. After machining the valve material through the rough machining facility, a rough-machined component is obtained. This rough-machined component is then transferred to the preliminary hardening facility via a conveyor between the rough machining facility and the preliminary hardening facility, where it is quenched. After the preliminary hardening facility, the rough-machined component is conveyed to the CNC lathe via a conveyor between the preliminary hardening facility and the CNC lathe, where the ground disc taper is finish-turned. The CNC lathe places the finished component, which has finished the taper, on a conveyor. The conveyor then transfers the finished component to the hardening machine for secondary quenching. After secondary quenching, the finished component is conveyed to the fine grinding facility, where the stem outer diameter, stem end face, locking clip groove, stem end chamfer, and disc taper are ground. Finally, the polished components are transferred to the polishing machine through the transfer device between the fine grinding equipment and the polishing machine for polishing, thereby obtaining the automobile engine valve.

[0020] In this embodiment, optionally, controlling the conveying equipment to convey the valve material to the rough processing equipment includes: performing equipment debugging on each processing equipment separately in a manual control manner.

[0021] Specifically, before producing automobile engine valves, each device can be manually debugged. Only when all devices are debugged normally can the automatic mode be turned on to control all devices to automatically produce automobile engine valves.

[0022] In this embodiment, optionally, rough processing of the valve material is performed by rough processing equipment, including: Use the position sensor to detect whether the valve material is delivered to the processing range of the rough processing equipment; In response to the valve being ineffectively conveyed into the machining range, the rough machining device performs rough machining on the valve material.

[0023] Specifically, the rough processing equipment is equipped with a position sensor, which can detect whether there is valve material in the processing range of the rough processing. When the valve material is transferred to the processing range, the rough processing equipment can automatically clamp the valve material for processing.

[0024] In this embodiment, optionally, performing preliminary quenching on the rough-machined component by a preliminary quenching device includes: monitoring the real-time temperature of the rough-machining element and converting the temperature monitoring data into floating-point data; The floating point data is compared with a temperature threshold, and the heating temperature of the preliminary quenching device is controlled according to the comparison result.

[0025] Specifically, the preliminary quenching equipment is equipped with a temperature detector, which can monitor the temperature of the rough-machined component undergoing quenching in real time. The temperature monitoring data detected by the temperature detector can be converted into floating-point data within a certain range, so that the preliminary quenching equipment can compare the floating-point data with a preset temperature threshold. If the real-time temperature of the rough-machined component is less than the minimum temperature threshold, the preliminary quenching equipment increases the power to heat the rough-machined component. If the real-time temperature is greater than the maximum temperature threshold, the preliminary quenching equipment reduces the power to cool the rough-machined component. The control method of the quenching machine is the same as that of the preliminary quenching equipment and will not be repeated here.

[0026] In this embodiment, optionally, cutting a conical surface of the disk on the preliminarily quenched rough-machined component by a CNC lathe comprises: The sensor detects whether a rough processing component is transmitted to the CNC lathe; In response to detecting that the rough-machined component is transferred to the CNC lathe, the CNC lathe is controlled to cut a disk tapered surface on the preliminarily quenched rough-machined component.

[0027] Specifically, the CNC lathe is equipped with a sensor for detecting whether the rough-processing component has been delivered to the position. When the rough-processing component is delivered to the processing position of the CNC lathe, the sensor can send a signal to the CNC lathe, triggering the CNC lathe to control the robotic arm to clamp the rough-processing component to the processing area for cutting.

[0028] In this embodiment, optionally, the method further includes: testing the quality of the automobile engine valve, and if the automobile engine valve is unqualified, transmitting the polished automobile engine valve to an unqualified area.

[0029] Specifically, a device is provided for detecting the quality of the produced automobile engine valves, and judging whether the produced automobile engine valves are qualified based on the detection results. If they are unqualified, the unqualified engine valves can be transported to the unqualified area for storage through the conveying equipment.

[0030] In this embodiment, optionally, the following is further included: Real-time acquisition and pre-processing of operating status data of roughing equipment, preliminary quenching equipment, CNC lathes, quenching machines, fine grinding equipment, and polishing machines; Extract the operation characteristic codes of rough processing equipment, preliminary quenching equipment, CNC lathe, quenching machine, fine grinding equipment and polishing machine from the corresponding operation status data respectively; According to the corresponding operation feature codes, the fault types and locations of rough processing equipment, preliminary quenching equipment, CNC lathes, quenching machines, fine grinding equipment and polishing machines are detected through the corresponding fault identification models.

[0031] Specifically, during the production process, operating status data for roughing equipment, preliminary hardening equipment, CNC lathes, hardening machines, fine grinding equipment, and polishing machines can be uploaded to the data platform. The data platform deploys a multi-dimensional fault prediction model, which includes an acquisition layer, a processing layer, a feature extraction layer, a fault database, a decision layer, and an application output layer.

[0032] The acquisition layer is used to acquire operational data uploaded by rough processing equipment and preliminary quenching equipment, such as process parameters and sensor data. The processing layer preprocesses the uploaded operational status data, performing methods such as noise filtering, clock correction, missing value repair, and data standardization. The feature extraction layer extracts the operational feature codes of the relevant equipment from the preprocessed operational status data.

[0033] The fault database stores fault data for different devices, including the fault type and its corresponding operational signature code. Fault data for different devices can be extracted from the fault database to construct corresponding datasets. Fault recognition models corresponding to different devices can then be trained using these datasets. These trained fault recognition models for different devices are then deployed to the decision-making layer. In this embodiment, the fault recognition model can be a hybrid model formed by integrating multiple models, such as an LSTM time series model and an XGBoost classification model.

[0034] The operational feature codes extracted by the feature extraction layer are sent to the decision layer, where the fault model deployed detects the fault type and location of the relevant equipment. Finally, the output layer displays the fault type and location detected by the decision layer to the relevant client for display, allowing relevant personnel to resolve the fault.

[0035] In this embodiment, optionally, the rough processing equipment, preliminary quenching equipment, CNC lathe, quenching machine tool, fine grinding equipment and polishing machine are all provided with fault signal lights.

[0036] Specifically, when the data platform detects that the working status of a certain device is abnormal, the data platform can control the entire production line to stop production operations and control the fault signal light of the corresponding equipment to light up to alert the staff.

[0037] In this embodiment, optionally, the conveying device is provided with a trigger switch, and the trigger switch is configured to control the conveying device to stop working when the processing equipment of the next stage is in working state.

[0038] Specifically, the conveyor equipment between the equipment is equipped with a trigger switch. For example, the conveyor equipment between the roughing equipment and the preliminary quenching equipment is equipped with a trigger switch. This trigger switch can trigger the conveyor equipment to stop conveying the rough-processed components processed by the roughing equipment to the preliminary quenching equipment while the preliminary quenching equipment is quenching the rough-processed components until the preliminary quenching equipment completes quenching. This can prevent the phenomenon of materials occupying the processing position.

[0039] A computer program product includes a computer program / instruction, which implements the steps of the above-mentioned automobile engine valve processing method when executed by a processor.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
