Technical Field

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

[0002] In the automotive manufacturing industry, after the injection molding process, the holes on automotive parts need to be inspected. Appropriate inspection tooling is required. However, due to the different shapes and sizes of injection molded parts and the differences in hole positions, existing hole inspection tools are generally fixed by bolts when connecting the hole pins. When replacing the hole pins by bolts, special tools are required for both disassembly and installation, which increases the replacement time of the hole pins for inspection.

[0003] Therefore, we propose a hole position gauge for automotive injection molded parts. Utility Model Content

[0017] 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. Example

[0018] Please see Figures 1-3 The diagram shows a hole position gauge for an automotive injection molded part, comprising a base 1, a threaded rod 2 inside the base 1, the threaded rod 2 being threadedly connected to a hole position pin 3, handles 301 on both sides of the hole position pin 3, and a second hole position pin 4 on one side of the hole position pin 3. The second hole position pin 4 has a quick-locking mechanism 5 inside, comprising a guide block 501, a push rod 502, a spring 503, a positioning block 505, and a tensioning block 504. The guide block 501 is fixedly connected to the base 1, the push rod 502 is slidably connected inside the guide block 501, and the positioning block 505 is fixedly connected to the guide block 501. The hole position pin and the second hole position pin are connected through the base. The second hole position pin tightly presses against the quick-locking mechanism. The quick-locking mechanism, comprising the guide block, push rod, spring, positioning block, and tensioning block, allows for quick installation and removal of the second hole position pin, thereby reducing replacement time.

[0019] Furthermore, the push rod 502 tightly presses against the inner side of the two tensioning blocks 504, and the push rod 502 extends to the outer side of the base 1. By tightly pressing the tensioning blocks with the push rod, it ensures that the tensioning blocks tightly press against the second hole pile head.

[0020] Furthermore, the tension block 504 tightly presses against the spring 503, and the spring 503 tightly presses against the positioning block 505. By the tension block tightly pressing against the spring and the spring tightly pressing against the positioning block, it is ensured that the spring can stably keep the tension block in the designated position.

[0021] Furthermore, the positioning block 505 is fitted with a spring 503, and the positioning block 505 is slidably connected to the tensioning block 504. Through the positioning block, the spring, and the tensioning block, the tensioning block can be self-reset.

[0022] Furthermore, the hole head 3 is rotatably connected to the handle 301, and the handle 301 magnetically engages with the hole head 3. By engaging the hole head with the handle, installation and disassembly can be carried out without the use of additional tools, and the handle is also easy to store.

[0023] Furthermore, the guide block 501 is slidably connected to two tensioning blocks 504. The inner wall of the tensioning block 504 is provided with an inclined surface. Through the inclined surface of the tensioning block, it is ensured that the tensioning block can move according to the change of the push rod.

[0024] In this solution, the workflow is as follows: the base 1 is fixed in a horizontal position, and the hole pile head 3 is moved along the base guide rail to the initial detection position through threaded transmission. The operator can hold the handles 301 on both sides of the hole pile head to assist in fine-tuning the position.

[0025] Align the second hole pile head 4 with the hole position group of the component to be inspected, and the guide block 501 of the quick locking mechanism 5 inside it is connected with the base fixing interface to complete the positioning of the main body of the inspection tool.

[0026] Push the push rod 502 along the axial direction of the guide block 501 to compress the spring 503 to the limiting groove of the positioning block 505. At this time, the tensioning block 504 is in a contracted state.

[0027] When push rod 502 is pushed to the end of its stroke, the wedge-shaped surface of positioning block 505 contacts the inclined surface of tension block 504, driving the tension block to expand outward. Observe whether the red marking ring at the end of the push rod is completely submerged in the guide block. If it is completely hidden, it indicates that the lock is in place, and the LED indicator light changes from yellow to green.

[0028] Gently place the injection-molded part to be inspected on the positioning surface of the inspection fixture, so that the inspection hole fits into the hole head 3 and the second hole head 4.

[0029] Slowly press the component down to the testing reference surface. Hole position pile head 3 verifies the axial position accuracy of the hole through the thread self-locking function; the tensioning block 504 of hole position pile head 4 provides radial pressure feedback on the radial dimension and roundness of the hole.

[0030] Unlocking operation: Pull the push rod 502 outward until it is fully exposed, the spring 503 resets and drives the tension block 504 to retract; gently lift the component to remove it from the detection pin head to avoid scratching the surface; rotate the threaded rod 2 in the opposite direction to make the hole pin head 3 return to the safe position.
