[0020] It should be noted that the terms "first", "second", and so on (if any) in the specification of the present application are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of utility models consistent with some aspects of the present application.

[0021] With the development of the automobile industry, users' requirements for vehicle driving performance and comfort are increasing. As a key safety component of the automobile, the quality of the wheel is directly related to the safety, stability and aesthetics of the automobile driving, and the quality of dynamic balance is a key factor affecting the overall driving stability of the automobile.

[0022] At present, wheel production enterprises are facing many challenges. From blank casting to heat treatment, to mechanical processing, errors may be introduced at each production link, resulting in unbalanced products. At present, the cooperation between devices in the wheel production process is poor, information transmission is not smooth, and precise blank positioning and clamping cannot be achieved. The blank end face deformation detection link is missing or not perfect, which cannot effectively identify and avoid the influence of blank end face deformation on subsequent processing, resulting in uneven dynamic balance quality of the processed wheels, which is difficult to meet the increasingly stringent product standard requirements of automobile developers.

[0023] The utility model provides a kind of wheel machine processing dynamic balance quality control system, to improve the intelligent degree of wheel quality detection, improve wheel quality. Referring to Figure 1 , Figure 1The utility model provides a kind of structure schematic diagram of wheel machine processing dynamic balance quality control system is provided.The system includes roller conveyor 1, for conveying the blank of wheel;Code scanning identification device 2 is set to the entrance end of roller conveyor 1, for reading the identity information of blank;Blank end face deformation detection equipment 3 is arranged downstream of code scanning identification device 2, including laser displacement sensor, laser displacement sensor is used to scan the axial positioning surface of blank one circle and generates end face runout curve;Blank scheduling sorting system 4 is connected blank end face deformation detection equipment 3, and blank is distributed to different processing unit 11 according to end face runout curve;At least one processing unit 11, including numerical control machine tool, fixture and dynamic balance detection equipment, fixture has three axial positioning blocks that are evenly distributed in circumference, and axial positioning block is distributed with interval 120 °;Unit general control system 7 is connected code scanning identification device 2, blank end face deformation detection equipment 3, blank scheduling sorting system 4 and at least one processing unit 11 by databus, and unit general control system 7 is used to store end face runout curve, and sends positioning point data information indicated by end face runout curve to processing unit 11;The axial positioning block position of fixture is automatically adjusted according to positioning point data information, and realizes blank clamping positioning.

[0024] Roller conveyor 1, as the material transmission basis of entire system, roller conveyor 1 undertakes the ordered conveying task of wheel blank between different processing and detection links.Can ensure that blank moves stably and efficiently to each station, provides smooth logistics support for subsequent detection and processing operation, avoids production delay or process connection problem caused by poor material transmission.

[0025] Code scanning identification device 2 is set to the code scanning identification device 2 of roller conveyor 1 entrance end, and it is the key link for realizing accurate traceability and processing of blank information.When blank enters the system, the device reads the identity information (may be called electronic tag) carried on blank.Identity information can cover the model, batch, production process parameters and other key data of blank.Through the above-mentioned mode, the system can track and manage the whole life cycle of each blank, and provides accurate data support for subsequent differentiated processing according to blank characteristics.

[0026] Blank end face deformation detection equipment 3 downstream of code scanning identification device 2 is the pass of controlling initial quality condition of blank.The core component laser displacement sensor of it carries out all-around scanning around the axial positioning surface of blank, can accurately capture the runout change of blank end face in circumferential direction, and is directly presented in the form of end face runout curve.End face runout curve records the runout amplitude of different positions of blank end face in detail, for subsequent judgment whether blank meets processing requirement and determines optimum clamping position.

[0027] The blank scheduling and sorting system 4 performs in-depth analysis based on the received end face run-out curve, and accurately allocates the blank to different processing units 11 according to the preset sorting logic and standard. This process is equivalent to a precise diversion of the blank, ensuring that each blank can enter the most suitable processing flow according to its current state, thereby realizing the rational allocation and utilization of production resources and improving the efficiency and flexibility of the entire production system.

[0028] The at least one processing unit 11 provided in the system is the core place for precise processing of wheel blanks. Each processing unit 11 integrates a numerical control machine tool, a clamp, and a dynamic balance detection device, forming a complete processing center. Among them, the three axial positioning blocks evenly distributed at an interval of 120° on the clamp are carefully designed to provide stable and reliable clamping support for the blank, ensuring that the blank maintains accurate positioning during processing, thereby ensuring consistency in processing precision and quality.

[0029] Optionally, the processing unit 11 includes an automatic unit code scanning and recognition device 5, a unit feeding and lifting device 6, a unit general control system 7, and a unit first-order processing machine tool 8. After the automatic unit code scanning and recognition device 5 scans and recognizes the incoming blank information, it reads the corresponding blank detection data stored by the blank end face deformation detection device 3 through the unit general control system 7, automatically compensates the feeding and lifting through the unit feeding and lifting device 6 according to the program logic variable relationship, adjusts the positioning angle of the spindle of the unit first-order processing machine tool 8, and realizes the precise docking of the selected three points on the blank positioning surface with the three positioning blocks of the machine tool clamp.

[0030] The unit general control system 7 connects the code scanning and recognition device 2, the blank end face deformation detection device 3, the blank scheduling and sorting system 4, and each processing unit 11 through a data bus to form an organic whole. It is responsible for storing key data such as blank end face run-out curves, and sending positioning point data information to the processing unit 11 according to the preset program logic and algorithm. The data information guides the automatic adjustment of the axial positioning blocks of the clamp to achieve perfect docking with the best clamping point on the blank end face. Through the above-mentioned manner, the unit general control system 7 realizes centralized control and coordinated optimization of the entire production process, ensuring seamless connection and efficient operation of each link, and maximizing the advantages of intelligent production systems.

[0031] In one possible implementation, the laser displacement sensor of the blank end face deformation detection device 3 takes the valve hole position of the blank as the detection zero point, scans the axial positioning surface of the blank, and generates an end face run-out curve. The end face run-out curve indicates the positioning point data information, and the positioning point data information is the positioning point of the three 120° interval run-out values on the end face run-out curve within the first run-out threshold range.

[0032] The laser displacement sensor of the blank end face deformation detection device 3 sets the valve hole position of the blank as the reference zero point of the detection. The valve hole, as a prominent and standardized feature point on the wheel, provides accurate starting positioning for subsequent measurement, ensuring consistency and repeatability of the measurement process.

[0033] When the laser displacement sensor starts working with the valve hole as the zero point, it performs a comprehensive scan around the axial positioning surface of the blank. During this process, the sensor captures the runout of the blank end face at various positions in the circumferential direction. The runout data is then integrated into a detailed end face runout curve, which visually presents the runout amplitude variation of the blank end face at different positions.

[0034] The positioning point data indicated by the end face runout curve, the system searches for three positioning points with an interval of 120° in the curve, and the runout values of these three positioning points are within the set first runout threshold range. The first runout threshold range is a range set based on quality control standards and production process requirements, ensuring that the runout amplitude of the selected positioning points is within the acceptable error range and can meet the requirements of subsequent processing for the stability and accuracy of the blank clamping. It can also be considered as the three positioning points with the most similar runout values.

[0035] In one possible implementation, the unit total control system 7 includes a memory for storing the end face runout curve and a processor for generating the positioning point data information according to the end face runout curve.

[0036] The memory is used in the system to safely and completely store the end face runout curve generated by the blank end face deformation detection device 3. The end face runout curve not only records the runout amplitude of the blank end face at different positions, but also contains important information such as the initial state and potential defects of the blank. The memory not only needs to have sufficient storage capacity to cope with massive data in large-scale production, but also needs to be equipped with an efficient data management mechanism to support fast data retrieval and calling.

[0037] The processor is responsible for in-depth analysis and processing of the end face runout curve stored in the memory. Its core task is to accurately extract the positioning point data information from the curve according to the preset algorithm and logical rules. The processor first performs preprocessing on the end face runout curve, which includes filtering and denoising, curve smoothing, etc., to eliminate errors and interference in the measurement process and ensure the accuracy and reliability of the curve data. Next, the processor uses advanced mathematical algorithms to extract features from the curve and identify key feature points in the curve. Through the above methods, the processor can generate the most suitable positioning point data information for each blank, providing accurate guidance for subsequent processing operations.

[0038] Optionally, in the embodiment of the application, the blank after the machining unit 11 still needs to be cleaned by the semi-finished product cleaning machine 9 and detected by the dynamic balance detection device 10.

[0039] For example, in combination with the above system, the clamping process performed by the embodiment of the application can include that the wheel blank to be machined is conveyed to the blank end face deformation detection device 3 by the roller conveyor device 1; the incoming blank is scanned and recognized by the code scanning and recognizing device 2 to confirm the blank information, the blank end face deformation detection device 3 scans the positioning plane of the blank by a laser displacement sensor, finds the points with the closest 120° interval jump values on the circumferential plane jump curve, records and stores the detection data; the qualified blank is sorted to the corresponding machining unit 11 by the blank scheduling and sorting system 4; after the incoming blank information is scanned and recognized by the machining unit 11, the corresponding blank detection data stored by the blank end face deformation detection device 3 is read by the unit general control system 7; the positioning angle of the incoming lifting and the first spindle is automatically compensated according to the program logic variable relationship, the three points selected on the blank positioning plane are precisely docked with the three positioning blocks of the machine tool clamp, the optimal positioning and clamping of the blank is completed, and the positioning mode avoids the highest point and the lowest point on the circumferential jump curve of the blank end face positioning.

[0040] In summary, the technical scheme provided by the utility model fixes the lower mold of the multi-cavity differential pressure casting mold on the bottom plate through the first positioning pin of the outer positioning support and the second positioning pin of the inner positioning support, improves the stability of the connection between the lower mold and the bottom plate, thereby ensuring the continuity of the casting production and the casting yield.

[0041] Those skilled in the art can understand that Figure 1 The structure shown in the above-mentioned embodiments does not constitute a limitation on the structure of the utility model, and can include more or fewer components than the drawings, or combine certain components, or use different component arrangements.

The "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone.
