Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a testing tool for testing the insertion and withdrawal force of automobile plastic clips. Background Technology

[0002] Currently, the connection between plastic parts and the car body in the automotive industry is usually secured using plastic clips, such as... Figure 1 The buckle shown is widely used.

[0003] Because the snap-fit ​​is a functional component, performance testing of the snap-fit ​​is required for each batch of incoming materials. The main test item for determining whether the snap-fit ​​meets the requirements is the snap-fit ​​insertion and extraction force test. Current common testing methods are: 1. Sending the snap-fit ​​to a laboratory for testing using a specialized push-pull force tester; 2. Using methods such as... Figure 2 A handheld push-pull force meter is used to perform a simple insertion and extraction force test on the buckle. This method involves inserting the buckle into the buckle fixing block 10, and manually operating the push-pull force meter 6 forward or backward to move the buckle fixing block 10, causing the buckle to insert into or be pulled out of the buckle fitting block 9. The insertion and extraction force is then determined based on the reading on the push-pull force meter 6. However, these existing methods have the following problems: 1. Sending the buckle to a laboratory for testing is expensive and time-consuming; 2. Using the existing handheld push-pull force meter 6, because it lacks a positioning guide, can lead to inaccurate test values ​​and misjudgments due to inconsistencies between the direction of the push-pull force and the buckle assembly direction. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tool for testing the insertion and withdrawal force of automotive plastic clips. It can solve the problems of high testing costs and long testing cycles in existing automotive plastic clip insertion and withdrawal force testing methods, or inaccurate test values ​​and misjudgments when the direction of the push-pull force is inconsistent with the assembly direction of the clip during testing using handheld push-pull force testing equipment.

[0005] To solve the above problems, the technical solution of this utility model is: This automotive plastic buckle insertion and withdrawal force testing tool includes a base, a guide block, a push-pull force gauge fixed slide, a quick clamp, a push-pull force gauge, a buckle fixed slide, a fixed buckle insert base, a movable buckle insert, and a fixed buckle insert.

[0006] The fixed buckle insert base is fixed to the front end of the base with bolts. The fixed buckle insert is embedded in the fixed buckle insert base. The base is provided with slide rails on both sides in front of the fixed buckle insert. The buckle fixing slide is installed on the slide rail through its lower groove and can move back and forth along the slide rail. The movable buckle insert for fixing the buckle is embedded in the buckle fixing slide. The movable buckle insert is directly opposite the fixed buckle insert.

[0007] The push-pull force gauge fixing slide is located on the middle section of the base. The push-pull force gauge is fixed on the push-pull force gauge fixing slide. Guide blocks are provided on both sides of the push-pull force gauge fixing slide. The guide blocks are close to the two sides of the base to guide the movement of the push-pull force gauge.

[0008] The quick clamp is fixedly installed at the rear end of the base; the force measuring rod of the push-pull force gauge is connected to the buckle fixing slide, the force applying rod of the push-pull force gauge is connected to the quick clamp, and the quick clamp is pushed forward or pulled back by the quick clamp handle to realize the buckle insertion or removal of the fixing buckle insert, thereby completing the test of the buckle insertion and removal force.

[0009] A more specific embodiment of the above technical solution is that the movable buckle insert is provided with a movable buckle insert protrusion that cooperates with the buckle fixing slide and a buckle fixing groove that matches the measured buckle.

[0010] Furthermore, the fixed buckle insert is provided with a fixed buckle insert protrusion that cooperates with the fixed buckle insert base and a buckle insertion and withdrawal slot that matches the measured buckle.

[0011] Furthermore: the push-pull force gauge is model number: Adeberg HP-500.

[0012] Furthermore: the quick clamp's specification model is GH-304C.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: This invention, based on the original buckle testing method, replaces the original movable buckle fixing block 10 with a movable buckle insert 13. The movable buckle insert 13 moves along the guide rail, reducing the possibility of inconsistent force directions. At the same time, the push-pull force gauge 6 is installed on the push-pull force gauge fixed slide with a guide block, ensuring the consistency of the movement direction of the entire push-pull force gauge. In addition, using the quick-clamp handle on the quick clamp to apply force also ensures the consistency of the force direction. This solves the problem of inaccurate test values ​​and misjudgments when the push-pull force direction is inconsistent with the buckle assembly direction when using a handheld push-pull force device. It also solves the problem of high testing costs and long testing cycles when sending samples to the laboratory for testing with a dedicated push-pull force machine. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Figure 3 and Figure 4 A tool for testing the insertion and withdrawal force of automotive plastic clips includes a base 1, a guide block 2, a push-pull force gauge fixed slide 3, a quick clamp 4, a push-pull force gauge 6, a clip fixed slide 7, a fixed clip insert 11, a movable clip insert 13, and a fixed clip insert 14.

[0017] The fixed buckle insert base 11 is fixed to the front end of the base 1 with bolts. The fixed buckle insert 14 is embedded in the fixed buckle insert base 11. The base 1 in front of the fixed buckle insert 14 is provided with slide rails 12 on both sides. The buckle fixing slide 7 is installed on the slide rail 12 through its lower groove and can move back and forth along the slide rail 12. The buckle fixing slide 7 is inlaid with a movable buckle insert 13 for fixing the buckle 8. The movable buckle insert 13 is directly opposite the fixed buckle insert 14.

[0018] The push-pull force gauge fixing slide 3 is set on the middle section of the base 1. The push-pull force gauge 6 is fixed on the push-pull force gauge fixing slide 3. Guide blocks 2 are provided on both sides of the push-pull force gauge fixing slide 3. The guide blocks 2 are close to the two sides of the base 1 and can move along the base 1, thereby driving the push-pull force gauge fixing slide 3 and the push-pull force gauge 6 to move.

[0019] The quick clamp 4 is fixedly installed at the rear end of the base 1. The force measuring rod of the push-pull force gauge 6 is connected to the buckle fixing slide 7, and the force application rod of the push-pull force gauge 6 is connected to the quick clamp 4. The quick clamp 4 is pushed forward or pulled back by the quick clamp handle 5 to insert or pull out the buckle 8 to fix the buckle insert 14. The insertion or pulling force is displayed on the screen of the push-pull force gauge 6, thus completing the test of the plastic buckle insertion and pulling force.

[0020] The force gauge 6 and quick clamp 4 are existing technologies. In this embodiment, the force gauge 6 is model number: Adeberg HP-500; the quick clamp 4 is model number: GH-304C. Figure 5 and Figure 6 As shown, the movable buckle insert 13 is based on the buckle fixing block 10 with the addition of a movable buckle insert protrusion 13-1 that mates with the buckle fixing slide 7. Its buckle fixing groove 13-2 matches the tested plastic buckle. The fixed buckle insert 14 is based on the buckle mating insert 9 with the addition of a fixed buckle insert protrusion 14-1 that mates with the fixed buckle insert base 11. Its buckle insertion / extraction groove 14-2 matches the tested plastic buckle. To test different plastic buckles, the movable buckle insert 13 and fixed buckle insert 14 must be replaced with the ones that match the tested plastic buckle.

[0021] This invention achieves rapid measurement of buckle insertion and extraction force by using fixed tooling and a simpler operation method based on the original buckle testing method. It solves the problems of high testing costs and long testing cycles in existing testing methods, or inaccurate test values ​​and misjudgments when the direction of the push-pull force is inconsistent with the buckle assembly direction when using handheld push-pull force testing equipment.
