Description

Technical Field

[0001] This invention relates to the field of inspection tool technology, and in particular to an inspection tool for the surface of an automotive interior door panel assembly. Background Technology

[0002] Automotive interior door panels are a crucial component of the automotive interior, serving both functional and decorative purposes. They are manufactured through injection molding and are relatively large and structurally complex. Current automotive interior door panel assemblies are formed by welding multiple individual panels together. Therefore, to ensure high assembly precision when the welded interior door panel assembly is fitted onto the actual vehicle door sheet metal, a simulation test is required before shipment. This involves installing the interior door panel assembly in a door panel assembly fixture to simulate the installation process with the actual vehicle door sheet metal. This test verifies whether the dimensions, outline, and gaps between the welded interior door panel assembly and the vehicle door sheet metal meet the required standards.

[0003] Since the ideal assembly effect between the interior door panel assembly and the door sheet metal is zero gap, the inspection surface of the interior door panel assembly and the inspection fixture are completely aligned during inspection to simulate the zero-gap assembly effect between the interior door panel assembly and the door sheet metal. While existing automotive door panel assembly inspection fixtures can inspect the welded interior door panel assembly, there is a certain range of error in the inspection (a range of positive and negative errors exists within the zero-gap range). If the gap is within the positive error range, it will not affect the actual assembly effect; however, if the gap is within the negative error range, this negative error gap cannot be actually measured, meaning the actual measured gap is 0. This indicates a zero gap between the assembled interior door panel assembly and the door sheet metal. However, in this case, when the interior door panel assembly is actually assembled onto the door sheet metal, it will cause excessive contact between the interior door panel assembly and the door sheet metal, resulting in interference and causing abnormal noises from the door, affecting the quality of the vehicle. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a surface inspection tool for automotive interior door panel assemblies. During simulated testing of the automotive door panel assembly, the tool's inspection surface corresponding to key parts of the interior door panel assembly is adjusted to allow for surface clearance. Even if the key parts of the interior door panel assembly do not fit or contact the inspection surface of the tool, other parts of the interior door panel assembly will fit against the inspection surface. This allows for accurate measurement of the gap between the key parts of the interior door panel assembly and the door sheet metal after actual assembly. The tool determines whether the gap is zero, a specific gap, or if it is below zero, leading to excessive fit and interference. This, in turn, helps determine whether the interior door panel assembly is a qualified product.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an inspection fixture for automotive interior door panel assembly, including a base plate, a first contour block provided on the base plate, a detection surface provided on the surface of the first contour block, a clamping mechanism provided on the inner side of the first contour block, after the interior door panel assembly is fixed to the inspection fixture, a gap is provided between the inner side of the key part of the interior door panel assembly and the detection surface, and the inner side of the remaining part of the interior door panel assembly is in contact with the detection surface.

[0006] Specifically, the key parts of the interior door panel assembly are the upper half of both sides of the interior door panel assembly.

[0007] Specifically, the clamping mechanism includes a first clamping mechanism, which is arranged along the inner side of the first contour block. The first clamping mechanism includes a first base and a clamping block. The clamping block is connected to the first base and is fixedly connected to the base plate through the first base. The clamping block is provided with a pull clamp mechanism for driving the clamping block to move. The pull clamp mechanism includes a pull rope and a pull cable. One end of the pull rope is connected to the clamping block and the other end is connected to the pull cable. By pulling the pull rope through the pull cable, the clamping block or the connecting post on the back of the interior door panel assembly is released.

[0008] Specifically, the clamping mechanism further includes a second clamping mechanism located in the middle of the first contour block, and the second clamping mechanism is foldable.

[0009] Specifically, the second clamping mechanism includes a second base and a fixing block. The fixing block is connected to the base plate through the second base and is rotatably connected to the second base. The free end of the fixing block is provided with a connecting unit. The second base is provided with a fixing groove for clamping the fixing block. That is, the fixing block of the second clamping mechanism can be folded. When inspecting the interior door panel assembly, the fixing block is folded up and does not clamp or fix the interior door panel assembly. When inspecting the door panel body parts separately, such as the upper body parts or the lower body parts, the fixing block is opened.

[0010] Specifically, the first contour block includes a U-shaped contour block and a top contour block, wherein the top contour block is detachably connected to the base plate.

[0011] Specifically, the position of the U-shaped contour block corresponding to the key part of the interior door panel assembly is detachable.

[0012] Specifically, at the position corresponding to the top contour block, the top of the base plate is provided with a notch, and after the top contour block is connected to the base plate, the bottom of the notch is not higher than the top of the top contour block.

[0013] Specifically, it also includes a second contour block, which is located inside the top of the first contour block. The side of the second contour block protrudes from the side of the top of the first contour block. The top of the second contour block is provided with a second detection surface and a second detection line, which is used to detect the top flange of the interior door panel assembly.

[0014] Specifically, the detection surface is provided with detection lines for detecting the contour edges of the interior door panel assembly.

[0015] The beneficial effects of this invention are:

[0016] 1. This invention improves the detection surface of the first contour block by making the detection surface less sharp, so that there is a detection gap between the key parts of the interior door panel assembly and the detection surface, while other parts of the interior door panel assembly are in contact with the detection surface. The specific gap of the key parts of the interior door panel assembly is measured, and the actual fit between the interior door panel assembly and the door sheet metal after assembly is determined based on the measured gap. This determines whether the fit between the interior door panel assembly and the door sheet metal is zero gap, or whether there is a certain gap, or whether the interior door panel assembly and the door sheet metal are too close together, causing interference. This allows for a determination of whether the product is qualified.

[0017] 2. The top of the first contour block of the present invention is detachably connected, and the bottom of the recess of the bottom plate is not higher than the top of the top contour block. This part can simulate and detect the fit between the upper part of the interior door panel assembly and the glass sealing rubber strip. The top contour block is detachably connected, which makes it easy to check from the side of the bottom plate whether there are any indentations, exposed white, or broken skin on the upper part of the inner wall of the upper part after the interior door panel is assembled onto the door sheet metal.

[0018] 3. The present invention is provided with a foldable second clamping mechanism. When the second clamping mechanism is folded up, it can be used to clamp and fix the interior door panel assembly, thereby enabling the inspection of the interior door panel assembly; when the second clamping mechanism is unfolded, it can be used to clamp and fix individual interior door panels, thereby enabling the inspection of individual parts of the interior door panel assembly.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment of an automotive interior door panel assembly 5 relief inspection fixture includes a base plate 1. The base plate 1 is provided with a first contour block 2, which is an irregular ring shape. The ring shape is similar to the edge shape of the interior panel assembly. The surface of the first contour block 2 is provided with a detection surface 3. The inner side of the first contour block 2 is provided with a clamping mechanism 4. The clamping mechanism 4 is connected to the connecting post on the back of the interior door panel assembly 5 to realize the clamping and fixing of the interior door panel assembly 5. After the interior door panel assembly 5 is fixed to the inspection fixture, a gap is provided between the inner side of the key part of the interior door panel assembly 5 and the detection surface 3. That is, the local position of the first contour block 2 is treated to allow relief, so that a gap is formed between the local position of the interior door panel assembly 5 and the detection surface. The inner side of the remaining part of the interior door panel assembly 5 is in contact with the detection surface 3.

[0027] During testing, the connecting post on the back of the interior door panel assembly 5 is aligned with the clamping mechanism 4. The clamping mechanism 4 fixes the interior door panel assembly 5 to the inspection fixture through the connecting post. The edge of the interior door panel assembly 5 covers the inspection surface 3. Then, a measuring tool is used to measure the specific gap value between the key parts of the interior door panel assembly 5, such as the two sides of the upper part of the interior door panel assembly 5 and the inspection surface 3. The fit between the remaining parts of the interior door panel assembly 5 and the inspection surface 3 is observed. The product is judged to be qualified based on the size of the gap value, and whether there will be interference after actual installation on the vehicle, which may cause abnormal noise. For example, if the standard gap value is amm, and the measured gap value is amm or bmm (b is greater than a, and b-amm is within the allowable error range), then after actual assembly, the interior door panel assembly 5 will have zero gap with the door sheet metal. If the gap value is bmm, there will be a gap between the interior door panel assembly 5 and the door sheet metal, which is b-amm and within the allowable error range. In this case, there will be no interference between the interior door panel assembly 5 and the door sheet metal, preventing any abnormal noise. Therefore, the interior door panel assembly 5 is a qualified product. However, if the measured gap value is cmm (c is less than a, regardless of whether the difference between a and c is within the allowable error range), after actual assembly, the interior door panel assembly 5 will be excessively fitted to the door sheet metal, causing interference and resulting in abnormal noise. In this case, the interior door panel assembly 5 is a defective product.

[0028] The key parts of the interior door panel assembly 5 are the upper half of both sides of the interior door panel assembly 5, namely the upper body and / or the middle body.

[0029] The clamping mechanism 4 includes a plurality of first clamping mechanisms 41. The first clamping mechanisms 41 are arranged along the inner side of the first contour block 2. The first clamping mechanism 41 includes a first base and a clamping block. Preferably, the clamping block 411 is a pair of clamping blocks. The clamping block 411 is connected to the first base and is fixedly connected to the base plate 1 through the first base. The clamping block 411 is provided with a pull clamp mechanism 412 for driving the clamping block 411 to move. The pull clamp mechanism 412 includes a pull rope and a pull wire. One end of the pull rope is connected to the clamping block 411 and the other end is connected to the pull wire. By pulling the pull rope through the pull wire, the pair of clamping blocks open or close to clamp or release the connecting post on the back of the interior door panel assembly 5.

[0030] The clamping mechanism 4 further includes a second clamping mechanism 42, which is located in the middle of the first contour block 2 and is foldable. The second clamping mechanism 42 includes a second base 421 and a fixing block 422. The fixing block 422 is connected to the base plate 1 through the second base 421. The second base 421 is provided with a fixing groove 4211 for clamping the fixing block 422. The fixing block 422 is rotatably connected to one end of the fixing groove 4211 of the second base 421. The free end of the fixing block 422 is provided with a connecting unit, which is a connecting hole or a connecting post. That is, the fixing block 422 of the second clamping mechanism 42 can be folded. When the fixing block 422 is folded up, the inspection tool of the present invention can realize the inspection of the interior door panel assembly 5. When the fixing block 422 is opened, the fixing block 422 is inserted into the fixing groove 4211, realizing the fixing of the fixing block 422, so that the connecting unit is exposed. The welding post or welding hole of the door panel unit is connected to the corresponding connecting hole or connecting post, thereby realizing the fixing of the interior door panel unit parts, such as the upper body parts or the middle body parts, and realizing the inspection of the interior door panel unit.

[0031] The first contour block 2 includes a U-shaped contour block 21 and a top contour block 22. The top contour block 22 is detachably connected to the base plate 1. A notch 11 is provided at the top of the base plate 1 corresponding to the top contour block 22. After the top contour block 22 is connected to the base plate 1, the bottom of the notch 11 is not higher than the top of the top contour block 22. During actual assembly, the upper part of the top inner side of the interior door panel assembly 5 will be exposed, while the lower part will be in contact with the glass sealing rubber strip. During inspection, the top contour block 22 can be removed, and the upper part of the inner side can be inspected for indentations, exposed areas, or peeling using a rubber strip or a testing tool to simulate the rubber strip. This allows for inspection of the condition of the upper inner side of the interior door panel assembly 5 after assembly. The bottom plate 1 has a notch 11 at the top. The bottom of the notch 11 is not higher than the top of the top contour block 22, so as to avoid the top of the bottom plate 1 from obscuring the top of the interior door panel assembly 5, and to facilitate the inspection or observation of the upper body of the interior door panel assembly 5 from the side or back of the present invention.

[0032] The position of the U-shaped contour block 21 corresponding to the key part of the interior door panel assembly 5 is detachable, that is, the contour block at the surface of the U-shaped contour block 21 is detachable, which makes it easy to adjust and replace the contour block at this position, so as to be used for the detection of different products or products with different surface gap values.

[0033] It also includes a second contour block 6, which is located on the inner side of the top of the first contour block 2. The side of the second contour block 6 protrudes from the side of the top of the first contour block 2. The top of the second contour block 6 is provided with a second detection surface, that is, the second detection surface is perpendicular or nearly perpendicular to the detection surface 3 of the top contour block 22. The second detection surface is also provided with a second detection line. The gap between the top flange of the interior door panel assembly 5 and the door sheet metal and the outline of the top flange can be detected through the second contour block 6.

[0034] The detection surface 3 is provided with detection lines for detecting the outline edge of the interior door panel assembly 5. After the interior door panel assembly 5 is covered on the detection surface 3, the overlap between the outline edge of the interior door panel assembly and the detection lines is used to determine whether the interior door panel assembly 5 meets the requirements.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
