Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to an inspection tool for automotive trim parts. Background Technology

[0002] As an important component of automotive interior and exterior trim, the precision of automotive trim parts' dimensions, mounting holes, and boundary contours directly affects the overall assembly quality and appearance of the vehicle. During production, batch testing of automotive trim parts is necessary to ensure they meet design requirements.

[0003] Existing inspection methods primarily rely on manual measurement using calipers, vernier calipers, or simple comparison templates. These methods have several drawbacks: first, the positioning method is limited, requiring repeated adjustments by operators during inspection, which can easily lead to errors; second, the inspection accuracy depends heavily on the operator's experience level, resulting in significant differences among individuals; and third, the inspection efficiency is low, failing to meet the demands of rapid inspection in mass production. While some companies have adopted simplified inspection fixtures, most of these fixtures can only perform single-dimensional comparisons, lacking rapid positioning and stable clamping capabilities. This causes the parts to easily shift during inspection, affecting the reliability of the results. Therefore, designing a new inspection fixture for automotive trim parts is essential.

[0006] According to the above technical solution, the base plate is a rectangular metal plate with mounting holes at its four corners for fixing to the workbench.

[0007] According to the above technical solution, the positioning pin is a cylindrical pin, which is vertically installed on the positioning reference block.

[0008] According to the above technical solution, the pressing device includes a base, a pressure rod hinged to the base, and a pressure head disposed at the end of the pressure rod. The pressure rod can be manually operated to press and release the ornament.

[0009] According to the above technical solution, the detection surface of the measuring fixture block is processed into a shape that matches the boundary contour of the decorative part.

[0010] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: This utility model, by providing a base plate, a positioning reference block, and positioning pins, achieves rapid and accurate positioning of automotive trim parts, avoiding errors caused by repeated adjustments during manual inspection; by providing a clamping device, the trim parts are reliably fixed during inspection, ensuring the stability and accuracy of the inspection; by providing an inspection fixture block, whose inspection surface matches the boundary of the trim parts, it is possible to intuitively determine whether the external dimensions of the trim parts meet the requirements; by providing scale lines, the inspectors can obtain intuitive dimensional references during comparison, improving operational efficiency.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example: Reference Figure 1 An automotive trim inspection fixture includes a base plate 1, a positioning reference block 2, a positioning pin 21, a clamping device 3, an inspection fixture block 4, and a scale line 5.

[0015] The base plate 1 is a rectangular metal plate with a thickness between 10 and 20 mm, serving as the mounting reference surface and load-bearing base for the inspection fixture. Mounting holes are machined at the four corners of the base plate 1 for fixing it to the worktable surface with bolts, ensuring the overall stability of the inspection fixture. Scale lines 5 are evenly engraved along the long side of the surface of the base plate 1, with the scale lines in millimeters, serving as a reference for dimensional comparison during the inspection process.

[0016] Several positioning reference blocks 2 are fixedly installed on the upper surface of the base plate 1. Each positioning reference block 2 has a cubic block structure, and its bottom is fixedly connected to the base plate 1 by bolts. Each positioning reference block 2 has a positioning pin 21 at its upper end. The positioning pin 21 is a cylindrical pin, vertically installed on the positioning reference block 2, and can be inserted into the mounting hole of the ornament to achieve precise positioning of the ornament. Through the cooperation of multiple positioning reference blocks 2 and positioning pins 21, the degrees of freedom of the ornament can be restricted in both horizontal and vertical directions, thereby ensuring the accurate positioning of the ornament during the testing process.

[0017] The clamping device 3 is located on the side of the positioning reference block 2. The clamping device 3 adopts a pressure rod structure with a handle, and its base is fixed to the base plate 1 with screws. The pressure rod and the base are rotatably connected via a hinge shaft. A pressure head is provided at the front end of the pressure rod. When the pressure rod is pressed down, the pressure head contacts the upper surface of the ornament, firmly pressing the ornament onto the base plate 1, thus preventing the ornament from shaking or shifting during the inspection process and affecting the inspection accuracy. The clamping device 3 allows for quick locking and releasing through manual operation, improving inspection efficiency.

[0018] The inspection fixture block 4 is machined into a specific shape according to the outer boundary of the ornament, and its bottom is fixed to the base plate 1 with screws. The inspection surface of the inspection fixture block 4 matches the outer contour of the ornament. After the ornament is installed in place, the inspection fixture block 4 should fit tightly against the edge of the ornament. If there is a deviation, it indicates that the ornament does not meet the design requirements in terms of size or shape.

[0019] The working principle of this embodiment is as follows: In use, the ornament to be inspected is first placed on the base plate 1, ensuring its mounting hole mates with the positioning pin 21, thus achieving rapid positioning by the positioning reference block 2. Then, the operator presses down the pressure rod of the clamping device 3, causing the pressure head to press the ornament firmly, completing the locking process. Finally, the fixture block 4 is checked for fit with the boundary of the ornament. By comparing the fit with the scale markings 5, the quality of the ornament can be quickly determined. After inspection, the clamping device 3 is released, the ornament is removed, and one inspection cycle is completed.
