Description

Technical Field

[0001] This utility model relates to the field of automotive injection molded parts processing and testing technology, specifically a hole position gauge for automotive injection molded parts. Background Technology

[0002] Automotive injection molded parts refer to plastic parts used in various parts of automobiles, obtained by injecting molten plastic material into a mold and then cooling and solidifying it using the injection molding process. They are widely used in automotive interiors, exteriors, engine compartments, and chassis. These injection molded parts have advantages such as low cost, high production efficiency, flexible design, and light weight, playing a vital role in improving the performance, safety, comfort, and aesthetics of automobiles.

[0003] Authorization announcement number CN222086860U discloses a hole position inspection fixture for automotive injection molded parts. The technical solution is as follows: "It includes a processing table, and an assembly bracket is fixedly connected between the two sides of the outer wall of the processing table. Two assembly support rods are provided through the top of the assembly bracket, and an assembly receiving plate is fixedly connected between one end of the two assembly support rods." The beneficial effect is that the fixing sleeve is installed with its corresponding fixing extension abutment plate via a fixing slider, allowing the fixing extension abutment plate to move inside the fixed hollow horizontal plate. This facilitates the fixing extension abutment plate to abut against both sides of the material, eliminating the need for manual support of the parts. This facilitates the inspection of parts of different specifications after fixing, thereby improving the usage effect.

[0004] The above technical solution has the following defects: the assembly receiving plate and the assembly cylinder are fixedly connected. Since the detection pin is fixedly installed at the bottom of the assembly receiving plate, it is difficult to disassemble and replace the assembly receiving plate. This means that the detection pin can only detect the hole positions of the corresponding automotive injection molded parts, which reduces the scope of application and affects the efficiency of detection. Therefore, a hole position inspection tool for automotive injection molded parts is proposed to solve the problems mentioned above. Utility Model Content
