Description

Technical Field

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

[0002] In automotive parts manufacturing, the hole position accuracy of injection molded parts (such as dashboard brackets, door interior panels, bumper mounting brackets, etc.) directly determines the assembly compatibility and the overall vehicle sealing. If the hole position deviation exceeds the range, it may cause bolts to fail to be inserted, snap-fit ​​assembly to loosen, or even cause abnormal noises, water leakage and other malfunctions. Therefore, hole position inspection is a key quality control step before injection molded parts leave the factory.

[0003] However, existing inspection fixtures for automotive injection molded parts used for hole position inspection still have certain shortcomings. For example, some existing hole position inspection fixtures generally rely on manual hand-holding to adjust the position of the parts during the inspection process. However, manual support is difficult to guarantee the continuous stability of the parts' posture, which can easily lead to problems such as workpiece displacement, thus affecting the accuracy and reliability of the inspection results. Secondly, traditional inspection fixtures are usually only applicable to injection molded parts of a single specification, and when inspecting injection molded parts with other hole positions, it is necessary to change the inspection fixture, which is costly and lacks practicality.

[0031] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0032] Working principle: In use, the injection molded part is placed on the base 1, and then the motor 2 is started, driving the first bidirectional threaded rod 3 to move the clamping seats 4 on both sides toward each other, thereby limiting the two sides of the injection molded part. Then, the second conical tooth 9 is rotated, driving the connecting column 8 to move the corresponding two clamping plates 6 toward each other under the meshing action of the hexagonal rotating block 10 and the first conical tooth 7, thereby limiting the front and rear of the injection molded part, thus ensuring that the injection molded part is centered and fixed, thereby improving the accuracy of hole position detection. When hole position detection is required for injection molded parts of other specifications, first press the pressure plate 29 along the inside of the opening groove 32, driving the pressure rod 28 to drive the wedge block 30 to slide along the inclined surface on the inclined block 27, thereby driving the two The insert 26 moves towards the slide bar 23, compressing the spring 25 and disengaging the insert 26 from the insertion hole 31, thus releasing the restriction on the positioning block 18. Then, the positioning block 18 can be directly pulled out along the inside of the positioning groove 17 to complete the disassembly of the positioning block 18, connecting plate 19, and detection rod 20. Then, the positioning block 18 with the new detection plate is aligned with the positioning groove 17 and inserted. When the insertion hole 31 on the positioning groove 17 corresponds to the insert 26, the pressure plate 29 is released. Under the rebound force of the slide bar 23, the insert 26 will automatically insert into the insertion hole 31, thus completing the installation of the new detection plate with the detection rod 20 corresponding to the new hole position, to adapt to multi-specification detection requirements and reduce the cost of inspection tools.
