[0020] 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.

[0021] Please see Figure 1-7 This utility model provides a technical solution: a vehicle tailgate lock outward opening handle assembly inspection tool, including a base plate 1 and a foot pad 2 fixed to the bottom of the base plate 1. A flip detection component 3 is installed on the rear side of the base plate 1, and a positioning component 4 is installed on the front side of the flip detection component 3. The positioning component 4 includes a positioning surface 401, a positioning sleeve 402 and a locking handle 403. Two sets of positioning sleeves 402 are provided on the side of the positioning surface 401 away from the flip detection component 3. Two holes are opened on the positioning sleeves 402, and the positioning sleeves 402 are placed in the holes. The two mounting bolts of the vehicle tailgate lock outward opening handle assembly part to be inspected are placed in the positioning sleeves 402, and a locking handle 403 is provided below the positioning sleeves 402. At the same time, the locking handle 403 is provided with threads inside, and the locking handle 403 is used to lock the part to be inspected.

[0022] The flip detection assembly 3 in this example includes a support 301, a connecting block 302, a flip arm 303, a rotating pin 304, a limiting pin 305, and a detection block 306. The connecting block 302 is mounted on the support 301. The flip arm 303 is disposed in the opening groove of the connecting block 302. The rotating pin 304 passes through the left end of the connecting block 302 and the flip arm 303, and the limiting pin 305 passes through the right end of the connecting block 302. The detection block 306 is connected to the right side of the flip arm 303. The connecting block 302 is fixedly connected to the support 301 by bolts, and the detection block 306 is fixedly connected to the flip arm 303 by bolts. The flip arm 303 drives the detection block 306 to rotate around the rotating pin 304. The limiting pin 305 is used to fix the position of the flip arm 303 and the detection block 306.

[0023] In this example, the positioning component 4 is fixedly mounted on the support 301 of the flip detection component 3 by screws. Using screws to fix the positioning component 4 facilitates the disassembly and installation of the positioning component 4.

[0024] In this example, a first placement seat 501 and a second placement seat 601 are installed on both sides of the upper surface of the base plate 1. The first placement seat 501 holds a surface gauge 5, and the second placement seat 601 holds a go / no-go gauge 6. The surface gauge 5 is used to detect the cut edge of the part, and the go / no-go gauge 6 is used to detect the profile of the part.

[0025] In this example, handles 7 are provided on both sides of the base plate 1. The handles 7 are made of aluminum and are fixed to both sides of the base plate 1 with screws. The handles 7 make it easy to hold and move the inspection tool.

[0026] In this example, the flip detection component 3, the first placement seat 501, and the second placement seat 601 are respectively mounted on the upper surface of the base plate 1 by screws or rivets, which facilitates the installation and disassembly of each component.

[0027] In this example, the foot pads 2 are locked to the bottom of the base plate 1 by threaded fastening, and there are four foot pads 2. The foot pads 2 are made of rubber and are used to support the entire inspection fixture.

[0028] Working principle: When using this automotive tailgate lock outward opening handle assembly inspection tool, first remove the limit pin 305, then rotate and open the flip arm 303 and the inspection block 306, and then remove the two mounting bolts (such as...) of the automotive tailgate lock outward opening handle assembly part to be inspected. Figure 7 (At point b) Align the fixture with the positioning sleeve 402 on the fixture and place the fixture on top. Then, use the two locking handles 403 to tighten the two bolts on the part to be tested to ensure that the bottom of the part is in contact with the positioning surface 401 on the fixture. When inspecting the part, rotate and close the flip arm 303 and the inspection block 306, and insert the limit pin 305. The distance from the three surfaces of the part to the inspection block is designed to be 3mm. Use a go / no-go gauge 6 to fill the 3mm gap. One end of the go / no-go gauge 6 is a go gauge, and the other end is a no-go gauge. The go gauge diameter is 2.5mm, and the no-go gauge diameter is 3.5mm. If the go gauge passes through but the no-go gauge fails, the part's surface is considered acceptable; otherwise, it is unacceptable. The cut edge of the part is inspected using a face difference gauge 5. The cut edge is designed with a flush plane as the inspection surface. One end of the face difference gauge 5 is attached to the inspection surface, and the other end is used to check whether the cut edge of the part exceeds the tolerance range. If it does not exceed the tolerance, it is acceptable; if it does, it is unacceptable. After inspection, the part can be removed, thus completing the entire work.
