[0002] In the production and maintenance process of hydraulic gear pumps, the assembly quality directly affects the performance, reliability and life of the pump. With the development of industrial automation and precision machinery, the assembly accuracy requirements for hydraulic gear pumps are getting higher and higher. Traditional assembly and inspection methods have been difficult to meet the high standards and high efficiency requirements of modern production. Traditional methods usually rely on manual measurement and visual inspection, which is not only inefficient, but the accuracy and repeatability of the results largely rely on the skills and experience of the operator, which is particularly problematic in situations with high precision requirements.

[0003] In addition, with the development of technology, the design of hydraulic gear pumps has become more and more complex, and the miniaturization and functional integration of its components have been continuously improved. This requires that every detail in the assembly process must be strictly controlled. Any slight assembly error may lead to a decrease in pump performance or even failure. Therefore, ensuring that each component is accurately assembled and positioned according to the design specifications has become the key to ensuring the quality of the final product. In order to solve these problems, a hydraulic gear pump assembly detection system came into being.

[0004] The limitations of the existing technology include at least the following problems. First, the traditional assembly inspection of hydraulic gear pumps often relies on manual inspection, which easily leads to unsystematic and incomplete data collection, and the omission of data and erroneous records in the manual inspection process will seriously affect the accuracy of the final assembly quality assessment. Secondly, traditional inspection methods usually lack the ability to comprehensively evaluate the assembly quality. Most methods may only focus on one or several aspects of inspection, such as simple angle or size inspection, while ignoring other key quality indicators, such as surface roughness or shape deviation, making it difficult to comprehensively evaluate the assembly quality.

[0024] The embodiment of the present application solves the problem that traditional assembly inspection of hydraulic gear pumps often relies on manual inspection, which easily leads to unsystematic and incomplete data collection, and data omissions and erroneous records in the manual inspection process will seriously affect the accuracy of the final assembly quality assessment. Secondly, traditional inspection methods usually lack the ability to comprehensively evaluate assembly quality. Most methods may only focus on one or several aspects of inspection, such as simple angle or size inspection, while ignoring other key quality indicators, such as surface roughness or shape deviation, making it difficult to comprehensively evaluate the assembly quality.

[0025] The overall idea of ​​the problem in the embodiment of this application is as follows:

[0026] First, the system collects necessary assembly data through the data acquisition subsystem, including the installation angle of each component, the distance between adjacent components and detailed information of the contact surface. This step is the basis for ensuring the accuracy of subsequent analysis. Then, the data analysis subsystem conducts a detailed analysis based on the collected data and calculates the angle detection index, linear dimension detection index and surface detection index respectively. These indicators each reflect the assembly quality of the hydraulic gear pump in different aspects. Finally, the comprehensive calculation subsystem integrates and analyzes various indicators to obtain a comprehensive assembly detection index. The judgment subsystem compares this index with the preset standard to determine whether the assembly quality of the hydraulic gear pump is qualified and identify any possible defects.

[0027] See also Figure 1The embodiment of the present invention provides a technical solution: a hydraulic gear pump assembly detection system, comprising: a data acquisition subsystem, a data analysis subsystem, a comprehensive calculation subsystem, and a judgment subsystem; the data acquisition subsystem is used to acquire the component angle data, component distance data, and component surface data of the assembled hydraulic gear pump; the data analysis subsystem is used to analyze the component angle data, component distance data, and component surface data of the assembled hydraulic gear pump respectively to obtain the angle detection index, linear size detection index, and surface detection index of the assembled hydraulic gear pump; the comprehensive calculation subsystem is used to comprehensively analyze the angle detection index, linear size detection index, and surface detection index of the assembled hydraulic gear pump to obtain the assembly detection index of the assembled hydraulic gear pump; the judgment subsystem is used to judge whether the assembly detection index of the assembled hydraulic gear pump meets the preset assembly detection reference index. If the assembly detection index meets the preset assembly detection reference index, the assembled hydraulic gear pump is regarded as normal. If the assembly detection index does not meet the preset assembly detection reference index, the assembled hydraulic gear pump is regarded as abnormal, and defect identification is performed.

[0028] Defect identification is specifically as follows: comparing the angle detection index, linear dimension detection index, and surface detection index of the assembled hydraulic gear pump with the standard angle detection index, standard linear dimension detection index, and standard surface detection index of the standard assembled hydraulic gear pump, and identifying unequal corresponding detection indicators.

[0029] For example: if the angle detection index of the assembled hydraulic gear pump does not meet the standard angle detection index of the assembled hydraulic gear pump, the angle detection index of the assembled hydraulic gear pump will be regarded as a defect, and an angle abnormality alarm will be sent; if the linear dimension detection index of the assembled hydraulic gear pump does not meet the standard linear dimension detection index of the assembled hydraulic gear pump, the linear dimension detection index of the assembled hydraulic gear pump will be regarded as a defect, and a linear dimension abnormality alarm will be sent; if the surface detection index of the assembled hydraulic gear pump does not meet the standard surface detection index of the assembled hydraulic gear pump, the surface detection index of the assembled hydraulic gear pump will be regarded as a defect, and a surface abnormality alarm will be sent.

[0030] The component angle data specifically refers to the installation angle value of each component in the assembled hydraulic gear pump obtained by a handheld or fixed digital angle meter. The component distance data specifically refers to the technician identifying and counting the number of adjacent components within a set range of each component in the assembled hydraulic gear pump through visual inspection, and obtaining the measured distance value between adjacent components through a laser rangefinder. The component surface data specifically refers to the technician identifying and counting the number of contact surfaces of each component of the assembled hydraulic gear pump through visual inspection, and obtaining the measured roughness of each contact surface through a surface roughness meter, and obtaining the measured shape deviation through a profilometer.

[0031] Specifically, the data analysis subsystem includes an angle detection index calculation module, a linear dimension detection index calculation module, and a surface detection index calculation module; the angle detection index calculation module is used to perform a comprehensive analysis based on the installation angle value of each component in the assembled hydraulic gear pump to obtain the angle detection index of the assembled hydraulic gear pump; the linear dimension detection index calculation module is used to perform a comprehensive analysis based on the number of adjacent components within a set range of each component in the assembled hydraulic gear pump and the measured distance values ​​between the adjacent components to obtain the linear dimension detection index of the assembled hydraulic gear pump; the surface detection index calculation module is used to perform a comprehensive analysis based on the number of contact surfaces of each component of the assembled hydraulic gear pump and the measured roughness and measured shape deviation of each contact surface to obtain the surface detection index of the assembled hydraulic gear pump.

[0032] In this implementation scheme, by accurately calculating the installation angle of each component, the distance between adjacent components and the surface quality of the contact surface, these modules can provide more detailed data analysis, thereby increasing the accuracy and reliability of the overall assembly quality detection. The systematic detection method makes it possible to identify and solve potential problems early in the production process, avoiding future failures and maintenance costs, thereby improving the overall life cycle performance of the product, and providing quantitative detection indicators, thereby helping decision makers make more informed maintenance and quality control decisions based on actual data rather than relying on empirical judgments. The analysis results can be fed back to the design and manufacturing teams for adjusting and optimizing product design and manufacturing processes to meet higher quality standards. The three independent module systems evaluate different aspects of assembly quality, ensuring a comprehensive review of the quality of each part of the hydraulic gear pump, expanding from a single angle to all-round detection in three-dimensional space. The specialized functions of each module provide a standardized process for testing and evaluation, which helps maintain consistent quality control standards and ensures that each product undergoes the same rigorous testing. Accurate angle and size detection ensures the correct assembly of mechanical parts, reduces performance problems caused by assembly errors, and enhances the overall performance and efficiency of the machine.

[0033] Specifically, Figure 2 As shown, the specific steps for obtaining the assembly inspection index of the assembled hydraulic gear pump are as follows: read and analyze the angle inspection index, linear size inspection index, and surface inspection index of the assembled hydraulic gear pump, and perform scalar processing; based on the scalar processing, perform a comprehensive analysis on the angle inspection index, linear size inspection index, and surface inspection index of the assembled hydraulic gear pump to obtain the assembly inspection index of the assembled hydraulic gear pump.

[0034] The specific formula for calculating the assembly inspection index of the assembled hydraulic gear pump is as follows: ;in, It is the assembly inspection index of the assembled hydraulic gear pump. It is the angle detection index of the assembled hydraulic gear pump after scalar processing. is the weight coefficient of the preset angle detection index stored in the database, is a natural constant, It is the linear dimension detection index of the assembled hydraulic gear pump after scalar processing. The weight coefficient of the preset linear dimension detection index stored in the database, It is the surface inspection index of the assembled hydraulic gear pump after scalar treatment. is the weight coefficient of the preset surface detection index stored in the database, .

[0035] This item is used to enhance The impact of this makes its growth more sensitive. This item is used to stabilize , making its growth tend to be flat when the value is large.

[0036] The specific process of presetting the weight coefficient is: adding the standard angle detection index, standard linear dimension detection index, and standard surface detection index of the standard assembled hydraulic gear pump, and since the values ​​of the various detection indicators of the standard assembled hydraulic gear pump offset each other, it can be seen from the calculation formulas of the angle detection index, linear dimension detection index, and surface detection index, there are no values ​​with units, so they can be directly added to obtain the total detection index, and the standard angle detection index, standard linear dimension detection index, and standard surface detection index of the standard assembled hydraulic gear pump are respectively ratio analyzed with the total detection index, and the ratio results are used as the weight coefficients of the corresponding detection indicators.

[0037] Among them, the calculation data examples of the assembly inspection index of the assembled hydraulic gear pump are as follows:

[0045] The fifth group of data: Angle detection index of the assembled hydraulic gear pump after scalar processing: 0.4; weight coefficient of the preset angle detection index stored in the database: 0.25; linear dimension detection index of the assembled hydraulic gear pump after scalar processing: 8; weight coefficient of the preset linear dimension detection index stored in the database: 0.25; surface detection index of the assembled hydraulic gear pump after scalar processing: 3.5; weight coefficient of the preset surface detection index stored in the database: 0.5; assembly detection index of the assembled hydraulic gear pump: about 1.213, and the unit is radian, and is within the typical output range of the arctan function, that is, arrive between.

[0046] In this implementation scheme, by performing weight analysis on purely quantitative detection indicators, quantitative comparison and evaluation of various detection indicators are allowed. This method provides clear data support to help decision makers make accurate judgments based on data rather than relying on subjective experience. This method is particularly important in production environments involving large or complex assembly operations. The purely quantitative processing and weighting of various detection indicators in the system allow different assembly quality problems to be carefully diagnosed. For example, by comparing the actual angle detection indicator with the preset standard, the angle error can be accurately found, and the precise analysis of linear dimensions and surface quality further ensures the accuracy of assembly and the reliability of the product. The automated data analysis and comprehensive calculation process greatly improves the efficiency and accuracy of detection, and reduces human intervention through the automated system. and errors, making assembly inspection faster and more consistent, especially in high-volume industrial environments. Through comprehensive analysis of multiple key quality indicators of the assembled hydraulic gear pump, such as angles, linear dimensions, and surface inspection, the system can comprehensively evaluate the assembly quality of the hydraulic gear pump. This comprehensive inspection not only improves the overall reliability of the product, but also reduces failures that may be caused by assembly defects. By using preset weight coefficients and standardized inspection indicators, the system ensures that the inspection results between different batches and different operators are highly consistent. This standardization is essential to ensuring product quality standards and meeting compliance requirements. The data obtained through systematic analysis can be used to feed back into the design and production process to guide how to improve product design and assembly processes to reduce future quality problems and optimize product performance.

[0047] Specifically, Figure 3 As shown, the specific steps for obtaining the angle detection index of the assembled hydraulic gear pump are as follows: read the installation angle value of each component of the assembled hydraulic gear pump, and obtain the corresponding installation reference angle value and the maximum angle allowable error; conduct a comprehensive analysis based on the installation angle value of each component of the assembled hydraulic gear pump, the corresponding installation reference angle value and the maximum angle allowable error to obtain the angle error score of each component of the assembled hydraulic gear pump; conduct a comprehensive analysis on the angle error score of each component of the assembled hydraulic gear pump to obtain the angle detection index of the assembled hydraulic gear pump.

[0048] The specific formula for calculating the angle detection index of the assembled hydraulic gear pump is as follows: ;in, It is the angle detection index of the assembled hydraulic gear pump. For the assembled hydraulic gear pump The installation angle value of each component, For the assembled hydraulic gear pump The installation reference angle values ​​of each component are obtained from the design specification and operation manual of the hydraulic gear pump. For the assembled hydraulic gear pump The maximum allowable angle error of each component is the maximum angle deviation allowed in the design specification. It is determined by the fault tolerance range based on industry safety standards and historical experience. This item is the first one in the assembled hydraulic gear pump Angular error score of each component, For the assembled hydraulic gear pump The weighting factor for the angular error score of each component, , is the number of parts in the assembled hydraulic gear pump.

[0049] The weighted coefficient of the angle error score is specifically obtained by the following process: the angle error scores of each component of the assembled hydraulic gear pump are added to obtain the total angle error score, and then the angle error scores of each component of the assembled hydraulic gear pump are ratio analyzed with the total angle error score, and the corresponding ratio results are used as the weighted coefficients of the corresponding angle error scores.

[0050] In this embodiment, by accurately measuring the installation angle of each component and comparing it with a preset reference angle value, the system can accurately identify any deviation that exceeds the allowable error range. This method provides a repeatable and standardized evaluation method to ensure that each assembled component meets or exceeds the set quality standards. Accurate control of angle errors is essential to ensuring the overall performance and efficiency of mechanical equipment. Minor deviations in angles may cause unstable mechanical operation, increased wear or failure. Through meticulous angle detection and adjustment, the system helps to improve assembly quality, thereby optimizing the operating efficiency and life of the machinery. The implementation of the system can detect and correct errors in the early stages of production, thereby reducing the number of parts that need to be reworked or replaced, reducing production costs and time. In addition, by maintaining high quality standards, In order to reduce after-sales service and warranty costs caused by quality problems, the angular error of each component is quantified and standardized to solve the subjectivity and inconsistency problems that may exist in traditional manual inspection methods. This standardized process ensures that the inspection of each assembly part is fair and consistent. The data support and analysis results provided by the system can help technicians and decision makers make fact-based decisions. For example, if a batch of parts frequently has installation angle errors, it may indicate problems in the supply chain or manufacturing process, thereby guiding further process optimization. By precisely controlling the angle error and conducting systematic error scoring and analysis, the system helps companies improve assembly efficiency and reduce mechanical failures and performance problems caused by angle errors, thereby improving overall production efficiency and product quality.

[0051] Specifically, the specific steps for obtaining the linear dimension detection index of the assembled hydraulic gear pump are as follows: read the number of adjacent components within the set range of each component of the assembled hydraulic gear pump and the measured distance values ​​between the adjacent components, and obtain the corresponding reference distance value and the maximum distance allowable error; for each component of the assembled hydraulic gear pump, perform a comprehensive analysis based on the number of adjacent components within the set range and the measured distance values ​​between the adjacent components, the corresponding reference distance value and the maximum distance allowable error to obtain the distance error score of each component of the assembled hydraulic gear pump; perform a comprehensive analysis on the distance error score of each component of the assembled hydraulic gear pump to obtain the linear dimension detection index of the assembled hydraulic gear pump.

[0052] The specific formula for calculating the linear dimension test index of the assembled hydraulic gear pump is as follows: ;in, It is the linear dimension detection index of the assembled hydraulic gear pump. For the assembled hydraulic gear pump The component is within the set range The measured distance between adjacent components. For the assembled hydraulic gear pump The component is within the set range The reference distance value between adjacent components is obtained from the design specification and operation manual of the hydraulic gear pump. For the assembled hydraulic gear pump The component is within the set range The maximum allowable distance error between adjacent components is obtained based on the tolerance and accuracy standards in mechanical engineering. This item is the first one in the assembled hydraulic gear pump The distance error score of each component, For the assembled hydraulic gear pump The proportionality factor for the distance error score of each component, , is the number of parts in the assembled hydraulic gear pump, , The number of adjacent components within the set range of the component.

[0053] The proportional coefficient of the distance error score is specifically obtained by the following process: the distance error scores of each component of the assembled hydraulic gear pump are added together to obtain the total distance error score, and then the distance error scores of each component of the assembled hydraulic gear pump are respectively ratio-analyzed with the total distance error score, and the corresponding ratio results are used as the proportional coefficients of the corresponding distance error scores.

[0054] In this implementation scheme, by systematically calculating and analyzing the deviation between the actual distance between the assembled parts and the preset reference distance, the system can ensure that each part is assembled strictly in accordance with the design specifications. This precise control of the distance error in the assembly process not only improves the overall assembly accuracy of the product, but also increases the consistency between different product batches. The detailed error data provided by the system can be used to provide feedback to the design and production teams, guiding them to adjust possible structural deficiencies or inaccuracies in the production process in future design iterations. This feedback loop can significantly improve the practicality of product design and the efficiency of the production process. Accurate distance error analysis helps to identify assembly problems that may cause mechanical failure or performance degradation in advance, thereby reducing subsequent maintenance needs and costs caused by assembly errors, which is very important for machines with harsh operating conditions or high maintenance costs. The implementation of this system standardizes the detection and evaluation process of distance errors between components in hydraulic gear pumps. By comparing the actual measurement value with the preset reference distance and calculating the error score, this method provides an objective and consistent evaluation standard, which helps to standardize quality control in the industry. By comprehensively analyzing the distance error score and calculating the linear dimension detection index, the system can reliably control and ensure the assembly quality. This method ensures that each assembled component is within the allowable error range, thereby ensuring the ultimate performance and safety of the machine. The implementation of the system makes quality control in the assembly process data-driven rather than relying on experience or subjective judgment. This method not only improves the efficiency and accuracy of quality control, but also provides real-time data support for continuous quality improvement, which helps the manufacturing industry stay ahead in the highly competitive market.

[0055] Specifically, the specific steps for obtaining the surface inspection index of the assembled hydraulic gear pump are as follows: read the number of contact surfaces of each component of the assembled hydraulic gear pump and the measured roughness and measured shape deviation of each contact surface, and obtain the maximum allowable roughness and maximum allowable shape deviation of each contact surface of each component. The contact surface refers to the part of the surface where the component is in direct contact with the adjacent component. The maximum allowable roughness and maximum allowable shape deviation are specifically obtained through industry-specific standards, such as ISO, ASTM, DIN, etc.; for each component of the assembled hydraulic gear pump, normalization processing is performed based on the measured roughness, measured shape deviation, maximum allowable roughness and maximum allowable shape deviation of each contact surface, and a comprehensive analysis is performed based on the normalization results to obtain the surface quality score of each component of the assembled hydraulic gear pump; the surface quality score of each component of the assembled hydraulic gear pump is weighted analyzed to obtain the surface inspection index of the assembled hydraulic gear pump.

[0057] The weighted coefficient of the surface quality score is specifically obtained by the following process: the surface quality scores of each component of the assembled hydraulic gear pump are added together to obtain the total surface quality score; then the surface quality scores of each component of the assembled hydraulic gear pump are ratio analyzed with the total surface quality score, and the corresponding ratio results are used as the weighted coefficients of the corresponding surface quality scores.

[0058] In this embodiment, the surface quality of each contact surface, such as roughness and shape deviation, is accurately measured and controlled, which directly affects the performance and durability of the hydraulic gear pump. Good surface treatment can reduce wear, leakage and potential failures, thereby extending the service life of the product and improving its operating efficiency. By comparing the measured values ​​with industry standards such as ISO, ASTM, DIN, etc., the system can ensure that all assembly parts meet the same high standards. This consistency is the key to quality control in large-scale production and helps maintain brand reputation and customer satisfaction. Real-time quality monitoring and feedback can help identify problems in the production process, allowing immediate adjustment of production parameters or processes to avoid mass production problems. In addition, high-quality initial assembly reduces long-term maintenance requirements and related costs. Normalization and weighted analysis provide a quantitative method to evaluate the quality of each contact surface, ensuring that all parts not only meet design specifications, but also meet functional and durability requirements. This method provides an evaluation process that can be tracked and recorded, increasing the transparency and traceability of the manufacturing process. Through systematic data analysis, the inspection system provides detailed insights into assembly quality. These data support fact-based decision making, including quality control, production adjustments and improvement measures. This data-driven approach helps to accurately identify the source of the problem and quickly implement a solution strategy.

[0059] In summary, this application has at least the following effects:

[0060] By integrating multiple detection modules and technical means, the assembly quality of the hydraulic gear pump can be comprehensively evaluated. It is not limited to a single quality indicator, but covers multiple aspects such as angles, sizes and surfaces, thereby significantly improving the accuracy and systematicness of the detection and ensuring that each assembly link meets high quality standards.

[0061] By acquiring and analyzing assembly data in a timely and accurate manner, any deviations or errors in production can be quickly identified, allowing the manufacturing team to take prompt action to make adjustments. This not only optimizes the production process and reduces the possibility of errors and rework, but also significantly improves production efficiency and yield. In addition, a systematic data analysis and feedback mechanism also helps to continuously improve production processes and reduce production costs.

[0062] Accurate assembly testing ensures that products have met or exceeded quality standards before leaving the production line, improving product competitiveness in the market and customer trust. High-quality assembly reduces the failure rate caused by loose parts or excessive wear, further extending the service life of the product, reducing the need for repairs and maintenance, and providing users with greater value.
