Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically to a positioning fixture for automotive parts product mold modification. Background Technology

[0002] Automotive parts mold modification positioning fixtures are specialized tools used for precise inspection and positioning of workpieces after mold modification. Their core function is to verify whether the modified parts meet the design requirements. Through preset positioning datums and measuring components (such as gauge blocks and probes), they can quickly detect whether the dimensional accuracy, geometric tolerances, and key features of the workpieces meet the standards. At the same time, they can help determine the accurate position of the parts in subsequent processing or assembly, ensuring that the modified products match well with other components, reducing assembly errors, improving production efficiency and product qualification rate. They are key tooling for quality verification and production connection after mold modification. In the process of manufacturing automotive parts, some products have extremely complex shapes, with multiple curved surfaces, insert fitting parts, snap-fit ​​connections and other special structures. These complex structures make it difficult to accurately reflect the spatial position of the product through conventional 2D and 3D measurement methods. Conventional measurement methods can only obtain local two-dimensional or three-dimensional data of the product, which cannot fully and accurately reflect the actual positional relationship of the product in space. In particular, for key parameters such as the curvature change of curved surfaces, the fit of insert fitting parts, and the fitting accuracy of snap-fit ​​connections, the measurement results are significantly biased. This directly leads to the inability to judge whether the product meets the standards based on accurate measurement data during the product mold modification process, making it difficult to advance the mold modification work. Therefore, a positioning fixture for automotive parts is proposed to address the above problems. Utility Model Content

[0017] As a further implementation of this solution, the upper support member 62 includes an insert support block 621, which is fixed inside the debris drop hole 614 by bolts. The inner wall of the insert support block 621 is provided with contact grooves 622 arranged in an arc shape. To further explain, the insert support block 621 of the upper support member 62 is fixed by bolts, which is convenient for disassembly and replacement. The contact groove 622 is arranged in an arc shape and fits precisely with the insert mating part of the workpiece. It can intuitively reflect the mating accuracy, provide a reliable basis for mold modification, and improve the accuracy of detection. As a further implementation of this solution, an air blowing port 9 is provided in the middle of the front end of the support base 1. The air blowing port 9 is connected to the interior of the chip removal cavity 7. Chip removal holes 10 are provided on both sides of the support base 1 and are connected to the chip removal cavity 7. The two chip removal holes 10 are located at both ends of the chip removal cavity 7, and the chip removal cavity 7 is located below the connecting port 615. To further explain, the shape of the chip removal chamber 7 is adapted to the shape of the connecting port 615 to ensure that the chips can enter smoothly. The chip removal holes 10 on both sides accelerate the discharge of chips, avoid accumulation and affect the accuracy of the inspection tool.

The outer side of the fixed base 81 is fixedly connected to the bottom of the inner side of the chip discharge chamber 7. A rotating shaft 82 is rotatably connected to the inner side of the fixed base 81. A swing rod 83 is fixed to the top of the rotating shaft 82. A rectangular spring 84 is fixed to the top of the swing rod 83. Cleaning brushes 85 arranged linearly are glued to both sides of the rectangular spring 84. To further explain, the rectangular spring 84 is projected as a rectangle. The rectangular spring 84 increases the contact area with the cleaning brush 85, making it more firmly fixed. The airflow drives the swing rod 83 to shake, and the cleaning brush 85 cleans the debris on the inner wall of the chip removal chamber 7, enhancing the cleaning effect, maintaining smooth chip removal, and ensuring the long-term stable operation of the inspection tool. As a further implementation of this solution, the inspection plate 4 includes a plate body 41, a rod groove 42 is provided in the middle of the upper surface of the plate body 41, a rail groove 43 is provided in the lower surface of the plate body 41, the rail groove 43 is slidably connected to the positioning rail 2, and an external detection groove 44 is provided on one side of the upper surface of the plate body 41. To further explain, the track groove 43 of the inspection plate 4 slides with the positioning rail 2, and the rod groove 42 slides with the positioning rod 3 to ensure stable and accurate sliding. The external detection groove 44 provides guidance for the detection instrument, improves the detection accuracy of the inner curvature of the workpiece, and facilitates quick judgment on whether the product meets the mold modification requirements. As a further implementation of this solution, the detection mechanism 5 includes a buckle detection seat 51. The upper surface of the buckle detection seat 51 is provided with a buckle positioning groove 52 and a central hole 53 on the side near the support body 611. The central hole 53 is connected to the buckle positioning groove 52. A buckle positioning pin 54 is engaged inside the central hole 53. The projected shape of the buckle detection seat 51 is semi-circular. The buckle detection seat 51 is in close contact with the lower support member 61. The buckle detection seat 51 is located below the positioning rail 2. The top of the buckle positioning pin 54 has a conical structure. The buckle positioning groove 52 extends to the outside of the buckle detection seat 51. The central hole 53 is located at the center of the buckle positioning groove 52. To further explain, the snap-fit ​​detection seat 51 is semi-circular and fits tightly with the lower support 61. The conical snap-fit ​​positioning pin 54 and the extended snap-fit ​​positioning groove 52 accurately position the snap-fit ​​connection part of the workpiece. The conformity can be intuitively judged by the fit. The structure is compact and improves the detection efficiency.

[0018] Workflow: When using this automotive parts product mold modification positioning fixture, the automotive parts to be inspected are placed on the support mechanism 6. The support rib groove 612 of the lower support member 61 supports the main body of the workpiece, the bending support groove 613 supports the bending part of the workpiece insertion mating part, and the contact groove 622 of the upper support member 62 directly contacts the insertion mating part of the workpiece to achieve the initial positioning of the workpiece. By observing the fit between the workpiece and the support mechanism 6, it can be preliminarily determined whether the workpiece is qualified. For the snap-fit ​​connection part of the workpiece, it is placed in the snap-fit ​​positioning groove 52 of the snap-fit ​​detection seat 51, and the snap-fit ​​positioning pin 54 positions it. By observing the fit, it can be determined whether the snap-fit ​​connection part is qualified. When it is necessary to detect the curvature change on the inner side of the workpiece, the positioning rail 2 and the positioning rod 3 are used to make the inspection plate 4 slide with the positioning rail 2 through the rail groove 43 and slide with the positioning rod 3 through the rod groove 42, so as to achieve stable and precise sliding adjustment. The detection end of the external inspection instrument extends into the external detection groove 44. The external detection groove 44 provides accuracy and guidance for the movement of the detector end, thereby completing the detection of the curvature change on the inner side of the workpiece. Since the contact groove 622 is in direct contact with the insertion part of the workpiece, the friction between the insertion part of the defective workpiece and the contact groove 622 is large. The debris generated by long-term friction will fall into the chip removal chamber 7 through the chip drop hole 614 and the connecting port 615 below. Since the support base 1 is fixed to the workbench with bolts, it will not be disassembled in order to ensure the accuracy and levelness of the inspection tool. The operator can extend the air gun into the air blowing port 9 of the support base 1. The airflow will spread outward quickly through the center of the inner side of the chip removal chamber 7. During the airflow, the swing rod 83 will swing left and right around the connection between the rotating shaft 82 and the fixed base 81, and drive the cleaning brushes 85 on both sides of the rectangular spring 84 to rub against the inner side of the chip removal chamber 7 to further clean the attached debris, so that the airflow can be quickly discharged from the chip removal holes 10 on both sides along with the debris.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
