Description

Technical Field

[0001] The utility model relates to the field of detection of part holes, and particularly to a detecting fixture based on product position detection. Background Art

[0002] In the fields of machining and manufacturing, the detection of the aperture and position degree of part holes is a key link to ensure product quality. Whether the aperture and position degree of part holes meet the design requirements directly affects the assembly accuracy, working performance and service life of products. Therefore, high-precision and high-efficiency detection methods for aperture and position degree have always been the goals pursued by the manufacturing industry.

[0003] Traditional detection methods mostly adopt manual measurement, such as using tools like vernier calipers and internal micrometers for measurement. However, this method has obvious limitations:

[0004] Large measurement error: Manual measurement is easily affected by human factors, such as the technical level of the measurer, operating habits, visual errors, etc., resulting in inaccurate measurement results.

[0005] Slow detection speed: Manual measurement requires detecting each part one by one, with low efficiency and difficult to meet the needs of large-scale production.

[0006] Unstable detection results: Due to the existence of measurement errors, the multiple measurement results of the same part may have large differences, resulting in unstable detection results.

[0007] In order to overcome the deficiencies of traditional detection methods and improve detection accuracy and efficiency, various automated detection devices and systems have emerged in recent years. These devices and systems achieve automated detection of the aperture and position degree of part holes by adopting advanced sensors, control systems and data processing technologies. However, the existing automated detection devices still have problems in terms of complex structure, high cost and difficult maintenance, which limit their wide application in the manufacturing industry.

[0053] On the left and right sides of the detection frame 1, there are handle rods 10, which are convenient for the operator to move and operate the detection frame 1.

[0054] The present invention relates to a fixture for product position detection, mainly used for detecting the hole positions and position tolerances of products to be detected (such as mechanical parts). The fixture mainly consists of a detection frame 1, a reference table, reference pins, a pressing head, and a limit block 9, etc. Through the mutual cooperation of these components, the accurate detection of the hole positions and position tolerances of the product is realized.

[0055] Working principle

[0056] Detection frame 1: The detection frame 1 serves as the support structure of the entire fixture, and key components such as a reference table, a pressing head, and a limit block 9 are installed on it. The design of the detection frame 1 ensures the stability and reliability during the detection process.

[0057] Reference table: The reference tables are arranged in a line on the detection frame 1 according to the size and shape of the product to be detected. At the top of each reference table, there are reference holes 4, which are used to cooperate with the reference pins to realize the fixation of the product and the detection of the positions and diameters of the preset holes of the product to be detected. The number and layout of the reference tables are determined according to the detection requirements of specific products, ensuring that the product can be stably placed on the detection frame 1.

[0058] Reference pin: The reference pin is a key component for detecting the hole positions of the product. After the product to be detected is placed on the reference table, the reference pin will be inserted into the preset holes of the product. If the reference pin can be smoothly inserted into each preset hole, it indicates that the hole positions and position tolerances of the product meet the requirements, and it is a qualified product (OK); if the reference pin cannot be smoothly inserted into a certain preset hole, it indicates that there are hole position deviations or unqualified position tolerances in the product, and it is an unqualified product (NG).

[0059] Pressing head: The pressing head is used to press the product to be detected, ensuring that the product closely adheres to the reference surface stably during the detection process. The design and use of the pressing head can effectively prevent the product from moving or shaking during the detection process, ensuring the accuracy of the detection results.

[0060] Limit block 9: The limit block 9 is used in cooperation with the pressing head to limit the movement range of the product during the detection process. By adjusting the position and size of the limit block 9, the detection requirements of products with different sizes and shapes can be adapted. The function of the limit block 9 is to ensure the stability and reliability of the product during the detection process, preventing the product from affecting the detection results due to movement.

[0061] In summary, the fixture for product position detection according to the present invention realizes the precise detection of the hole position and positional tolerance of the product through the mutual cooperation of components such as the detection frame 1, the reference table, the reference pin, the pressing head, and the limit block 9. This fixture has the advantages of simple structure, convenient operation, and high detection accuracy, and can meet the requirements of modern manufacturing for high-precision and high-efficiency detection.
