Description

Technical Field

[0001] This utility model relates to the automotive field, and in particular to a tooling for detecting the length of a tailgate guard plate positioning post. Background Technology

[0002] In the automotive manufacturing industry, the rear sill protector is an important exterior and protective component of the vehicle body, and its precise assembly with the body panels is crucial. The rear sill protector not only needs to have excellent appearance quality to enhance the overall visual appeal of the vehicle, but also must fit tightly against the body panels after assembly to fulfill its protective function and prevent external factors from damaging the vehicle body.

[0003] However, in actual production, the dimensional accuracy of the rear sill guard plate is difficult to guarantee effectively. Due to many uncontrollable factors in the production process, such as mold wear and fluctuations in the injection molding process, deviations can easily occur in the length of the positioning pins on the rear sill guard plate and the spacing between adjacent positioning pins. If these dimensional deviations are not detected and corrected in a timely manner during production, they will directly affect the fit between the rear sill guard plate and the body sheet metal.

[0004] Traditional inspection methods often have many limitations. On one hand, some methods only inspect a single dimension of the positioning posts, such as measuring only the length of the positioning posts or only the spacing between adjacent posts. This single-dimensional inspection method cannot fully reflect the actual dimensions of the rear sill guard plate, easily overlooking potential problems. This leads to some dimensionally non-compliant products entering the subsequent assembly stage, causing quality issues such as assembly difficulties and excessive assembly gaps. These problems not only affect the overall appearance quality of the vehicle but may also reduce its protective performance, increasing rework and production costs later on.

[0005] On the other hand, traditional testing tools have shortcomings in terms of ease of operation and structural stability. Some testing tools are complex in design, requiring employees to spend a significant amount of time holding, aligning, and adjusting them. This not only reduces testing efficiency and makes it difficult to meet the needs of rapid quality inspection in mass production scenarios, but also increases the operational difficulty and labor intensity for employees. Furthermore, the structural design of some testing tools is not reasonable enough, and they are prone to loosening or deformation after long-term use. This can cause changes in the dimensional accuracy of the positioning holes, affecting the consistency of test results across multiple batches of products and failing to provide accurate and reliable testing data support for production.

[0006] Therefore, it is necessary to provide a tooling for detecting the length of the tailgate guard plate positioning post to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a tooling for detecting the length of the positioning post of the tailgate guard plate.

[0008] This utility model provides a tooling for detecting the length of a positioning post on a rear sill guard plate. The rear sill guard plate includes a plate body, and connecting seats are provided at equal intervals on the inner side of the plate body. The connecting seats and the plate body are integrally formed. The connecting seats are integrally provided with a buckle and a positioning post. The buckle and the positioning post are used to cooperate with corresponding slots and positioning grooves on the body sheet metal. The top of the positioning post is provided with a chamfer. The tooling plate includes a tooling plate. Both ends of the tooling plate are provided with downwardly bent and protruding detection parts. The detection parts are provided with positioning insertion holes that cooperate with the positioning post, and the two positioning insertion holes are symmetrically distributed relative to the tooling plate.

[0009] Preferably, the bottom of the detection unit is provided with a limiting surface for contacting the connecting seat.

[0010] Preferably, a U-shaped plastic handle is installed on the top of the tooling plate.

[0011] After the tail sill guard plate is fixed in place by tooling, the employee can use the tail sill guard plate positioning post length measuring tool to check the distance between two adjacent positioning posts on the tail sill guard plate to ensure that the length dimension of the tail sill guard plate is qualified. If both positioning posts can be inserted into the corresponding positioning holes and the limiting surface can be in contact with the connecting seat, it is judged as qualified; otherwise, it is considered as unqualified.

[0012] Preferably, the tooling plate has symmetrical mounting grooves on its top, and the end of the U-shaped plastic handle is positioned in the corresponding mounting groove. The tooling plate and the U-shaped plastic handle are fixedly connected by screws, making the connection between the tooling plate and the U-shaped plastic handle more stable.

[0013] The specific process is as follows: The symmetrically distributed positioning holes on the tooling plate, the limiting surface at the bottom of the inspection section, the U-shaped hand-held plastic handle and the positioning post of the tail sill guard plate, and the connecting seat structure form a one-to-one matching relationship. The spacing of the positioning holes is consistent with the spacing of the positioning posts required by the design, and the height of the limiting surface is adapted to the standard length of the positioning post, providing a structural basis for inspection. The employee holds the U-shaped plastic handle on the top of the tooling plate and aligns the two adjacent positioning posts on the tail sill guard plate with the corresponding positioning holes in the detection section at both ends of the tooling plate. To attempt to insert the two positioning pins into the positioning holes simultaneously, two verification conditions must be met at the same time: ① The positioning pins can be fully inserted into the corresponding positioning holes; ② The connecting seat of the tailgate guard plate is in close contact with the limiting surface at the bottom of the detection section. If both conditions are met, the length of the positioning pins and the spacing between adjacent positioning pins of the tailgate guard plate are deemed to be qualified, and the product can meet the requirements for vehicle assembly. If any of the following occurs: the positioning pin cannot be inserted into the positioning hole, or there is a gap between the connecting seat and the limiting surface after the positioning pin is inserted, the product size is deemed unqualified, and there is a deviation in the length of the positioning pin or the spacing between adjacent positioning pins, making it unsuitable for the positioning groove and slot assembly of the body sheet metal.

[0014] Compared with related technologies, the present invention provides the following beneficial effects: High testing accuracy: The positioning holes are symmetrically distributed relative to the tooling plate, accurately matching the positioning post spacing required by the design; the contact verification between the limiting surface and the connecting seat directly corresponds to whether the positioning post length meets the standard, realizing simultaneous detection of "spacing + length" in two dimensions, avoiding errors caused by a single detection dimension, and ensuring that the test results can directly reflect the assembly compatibility between the rear sill guard plate and the body sheet metal. Easy and efficient operation: The U-shaped plastic handle design makes it easy for employees to quickly grip and align, reducing the difficulty of aligning the positioning post and the positioning hole. No complicated debugging process is required, which greatly improves the testing efficiency and is suitable for the rapid quality inspection needs in mass production scenarios. Stable and reliable structure: The top of the tooling plate is fixedly connected to the U-shaped plastic handle by a combination of mounting slots and screws. The connection is firm and the assembly is stable, and it is not easy to loosen or deform after long-term use. The tooling plate and the inspection section adopt a rigid structure design, which can maintain the dimensional accuracy of the positioning holes for a long time and ensure the consistency of inspection of multiple batches of products. Highly practical and tailored to assembly requirements: The detection logic is directly linked to the core assembly points of the rear sill guard plate and the body sheet metal. The detection results can directly verify whether the product meets the vehicle installation requirements, avoiding subsequent assembly difficulties and excessive assembly gaps caused by dimensional deviations from the source, and reducing rework and production costs.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figures 1-5 A tooling for detecting the length of a positioning post on a rear sill guard plate is disclosed. Its structure and detection logic are as follows: The rear sill guard plate 2 consists of a plate body 3 forming the main frame. Multiple connecting seats 4 are equidistantly arranged along the length direction on the inner side of the plate body 3. The connecting seats 4 and the plate body 3 are integrally injection molded to form a rigid connection structure. Each connecting seat 4 is integrally integrated with a buckle 5 and a positioning post 6. The buckle 5 is used to achieve elastic engagement with the corresponding slot on the body sheet metal, while the positioning post 6 ensures assembly positioning accuracy through precise matching with the positioning slot on the body sheet metal. The top of the positioning post 6 is chamfered 7 to guide insertion and prevent scratch damage during assembly.

[0019] The core component of the inspection fixture is the fixture plate 8, which has downwardly bent and protruding inspection parts 9 at both ends. Inside each inspection part 9 are positioning holes 10 that match the diameter of the positioning pins 6. The two positioning holes 10 are symmetrically distributed with reference to the longitudinal centerline of the fixture plate 8, and the spacing strictly corresponds to the standard spacing value of adjacent positioning pins 6 in the design drawings. A limiting surface 11 is machined on the bottom surface of the inspection part 9. This limiting surface 11 forms a planar contact relationship with the top surface of the connecting seat 4, used to control the insertion depth of the positioning pins 6.

[0020] To improve ease of operation, mounting slots 13 are symmetrically opened on the top of the tooling plate 8. The two ends of the U-shaped plastic handle 12 are embedded in the corresponding mounting slots 13. The tooling plate 8 and the handle 12 are firmly mechanically connected by screws 1 to ensure stable and reliable grip during the testing process.

[0021] The specific testing process is as follows: The operator holds the U-shaped plastic handle 12 to lift the tooling plate 8, aligning the two adjacent positioning posts 6 on the rear sill guard plate 2 with the positioning holes 10 of the detection parts 9 at both ends of the tooling plate 8. During the vertical downward insertion process, two verification conditions must be met simultaneously: First, the positioning post 6 must be fully inserted into the corresponding positioning hole 10 without any jamming; second, the top surface of the connecting seat 4 of the rear sill guard plate 2 must form a tight fit with the limiting surface 11 at the bottom of the detection part 9, without any visible gap. If both conditions are met simultaneously, it is determined that the length of the positioning post 6 and the spacing between adjacent positioning posts 6 of the rear sill guard plate 2 meet the design requirements, and the product meets the vehicle assembly standards; if the positioning post 6 cannot be fully inserted into the positioning hole 10, or if there is a gap between the connecting seat 4 and the limiting surface 11, it is determined that the product dimensions are unqualified, there is a deviation in the length of the positioning post or an error in the spacing between adjacent positioning posts, and it cannot adapt to the assembly requirements of the corresponding positioning groove and slot of the body sheet metal, requiring rework and adjustment.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
