[0001] This utility model relates to the field of inspection tool technology, and in particular to an inspection tool suitable for inspecting the contours of long automotive interior parts. Background Art

[0002] For large interior parts of automobiles, such as the front defrost panel of the car dashboard, the front defrost panel is a long structural part with a complex structure and curvature. In order to ensure product quality and aesthetics, its outer contour needs to be inspected after the product is completed.

[0003] Refer to patent application number CN2022234844802, which discloses a vehicle front defroster panel inspection fixture, comprising a positioning block group fixed to a base plate, the base plate being equipped with multiple fixing mechanisms for fixing the vehicle front defroster panel; the base plate also being equipped with a simulation block for the instrument panel body matching area, a simulation block for the instrument panel end guard plate matching area, a simulation block for the front windshield matching area, a simulation block for the A-pillar upper guard plate matching area, a simulation block for the door guard plate trim matching area, and a product hole detection pin; and a detection block is detachably mounted on one side of the simulation block for the door guard plate trim matching area. After the inspection fixture positions the product to be inspected, it is necessary to use each simulation block and various go / no-go gauges to inspect the assembly dimensions of the product. Since the positions of each simulation block are fixed, the simulation block of the inspection fixture can only inspect a specific inspection point of the product and cannot inspect the entire inspection surface, resulting in poor inspection results. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a testing tool for detecting the contour of automobile interior parts. The testing tool detects the entire surface of the product to be tested by sliding detection, thereby solving the problem of poor detection effect in the past.

[0005] In order to solve the above technical problems, the utility model discloses a testing tool for detecting the contour of automobile interior decoration parts, including a profiling simulation block and a face difference gauge, the profiling simulation block is arranged along the length direction of the product to be tested, and the profiling simulation block is provided with a limit groove arranged along the length direction of the product to be tested; calibration blocks for calibrating the face difference gauge are provided on the side of the profiling simulation block or on both sides of the length direction of the product to be tested; during testing, the face difference gauge slides along the limit groove, and the working end of the face difference gauge abuts against the surface to be tested of the product to be tested.

[0006] The surface difference gauge includes a dial indicator and a base. The dial indicator is fixedly installed on the base, and the working end of the dial indicator extends out of the bottom of the base. The base can slide along the limiting groove.

[0007] The bottom of the base is detachably fitted with a limiting component; in the assembled state, the limiting component is inserted into the limiting groove.

[0008] Wherein, the limiting member is arranged in a cylindrical shape.

[0009] An adjustment component is also fixedly installed at the bottom of the limiting component.

[0014] The side wall of the limiting groove is an outwardly inclined limiting surface. When the surface gauge slides in the limiting groove, the limiting surface contacts the surface gauge to limit the surface gauge in a direction perpendicular to the sliding direction.

[0015] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: by setting a limit groove, the face difference gauge slides along the limit groove and performs linear detection on the surface to be detected of the product to be detected. This sliding detection method replaces the previous method of multiple fixed-point monitoring. The path that the face difference gauge slides along in the limit groove is the line of the surface to be detected that can be detected by linear detection.

[0023] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] This utility model discloses a specific embodiment of a detection tool for detecting the contour of automobile interior parts. Figure 1 Taking the front defroster panel of an automobile interior as an example, the inspection fixture includes a profiling block 3 and a flushness gauge 2. The profiling block 3 is arranged along the length of the product under test 1. Specifically, the profiling block 3 is arranged along the length of the product under test 1. The shape and structure of the profiling block 3 can be adaptively designed based on the outer contour of the product under test 1.

[0025] As an improvement, the profiling simulation block 3 is provided with a limit groove 31 set along the length direction of the product to be tested 1. During testing, the face difference gauge 2 slides along the limit groove 31, and the working end of the face difference gauge 2 abuts against the surface to be tested of the product to be tested 1. By sliding the face difference gauge 2 in the limit groove 31, the face difference gauge 2 can detect the surface to be tested of the product to be tested 1, thereby realizing a sliding detection structure. The sliding detection can realize linear detection of the surface to be tested. The path traveled by the face difference gauge 2 when sliding in the limit groove 31 is the line of the surface to be tested that can be detected by the linear detection. The linear detection can continuously and uninterruptedly detect the tolerances of all points on the entire line of the surface to be tested, thereby improving the accuracy of the detection and the efficiency of the detection.

[0026] In order to facilitate the calibration of the face difference gauge 2, a calibration block (not shown) for calibrating the face difference gauge 2 is provided on the side of the profiling simulation block 3. For example, a calibration block is set on the left or right side of the profiling simulation block 3. In addition, it is also possible to set a calibration block on the left or right side of the product to be tested 1. The main function is to achieve zero calibration of the face difference gauge 2. The main function of the calibration block is to serve as a reference to assist the face difference gauge 2 in calibration and zeroing.

[0027] Please see Figure 2 The flushness gauge 2 includes a dial indicator 22 and a dial base 21. The dial indicator 22 is fixedly mounted on the dial base 21, and the working end of the dial indicator 22 extends through the bottom of the dial base 21 and is retractable. Specifically, an arc-shaped mounting groove is formed at the upper end of the dial base 21. The dial indicator 22 is placed in the mounting groove, and the working end of the dial indicator 22 extends through the bottom of the mounting groove so that the working end of the dial indicator 22 extends through the bottom of the dial base 21. The main body of the dial indicator 22 is fixed to the dial base 21 by adhesive bonding, screw fixing, clamping, or other fixed installation methods. The specific setting can be selectively set according to actual needs.

[0028] In order to realize the sliding detection, the meter base 21 can slide smoothly along the limiting groove 31. For this purpose, a limiting member 23 is detachably installed at the bottom of the meter base 21. The detachable connection method can be a plug-in method. For example, a mounting hole is opened on the bottom surface of the meter base 21, and then the limiting member 23 is inserted into the mounting hole to realize the detachable connection between the limiting member 23 and the meter base 21. Alternatively, the limiting member 23 can be detachably installed on the meter base 21 by screws. In this embodiment, combined with Figure 3The limiting member 23 is cylindrical in shape, while the limiting groove 31 has an L-shaped cross-section. In the assembled state, the limiting member 23 is inserted into the limiting groove 31, and the bottom surface of the limiting member 23 is closely attached to the bottom of the limiting groove 31, while the outer peripheral side surface of the limiting member 23 is closely attached to the inner wall of the limiting groove 31. This ensures that the bottom and wall of the limiting groove 31 can double-limit the limiting member 23 as it slides along the limiting groove 31, making it less likely for the flush gauge 2 to tilt during sliding, thereby ensuring the accuracy of the test. Furthermore, a groove can be formed at the bottom of the limiting groove 31 along the length of the product 1 to be tested, with a groove width equal to or slightly larger than the outer diameter of the limiting member 23. The bottom of the limiting member 23 is inserted into the groove, and the groove limits the limiting member 23 in the front-to-back direction, thereby further improving the position of the limiting member 23. The front-to-back direction of the limiting member 23 is perpendicular to the sliding direction of the limiting member 23 along the limiting groove 31.

[0029] like Figure 1 As shown, when the surface to be tested of the product 1 to be tested is an outward-inclined contour surface, the sidewall surface of the limiting groove 31 is a first limiting surface inclined outward, and the bottom wall surface of the limiting groove 31 is a second limiting surface perpendicular to the first limiting surface. When the limiting member 23 slides in the limiting groove 31, the first limiting surface contacts the outer side surface of the limiting member 23, and the second limiting surface contacts the bottom surface of the limiting member 23, thereby limiting the limiting member 23 perpendicular to the sliding direction, thereby achieving sliding detection of the surface to be tested of the product 1 to be tested having an outward-inclined contour surface. This sliding detection can detect all points along the entire contour line of the contour surface, not only with high detection efficiency, but also with higher detection accuracy because the points detected on the contour surface are continuous and uninterrupted.

[0030] Combine Figure 3 and Figure 4 An adjusting component 24 is also fixedly installed at the bottom of the limiting component 23. The adjusting component 24 can also be fixedly installed at the bottom of the limiting component 23 in a detachable manner, for example, by using screws or clips to fix the adjusting component 24 to the bottom of the limiting component 23.

[0031] In this embodiment, the adjusting member 24 is provided in a disc shape, and the adjusting member 24 may be an ellipse or a perfect circle. Figure 4The dotted lines in the diagram represent the positions of the dial gauge 2 after changing the size of the adjusting element 24. By changing the adjusting element 24 to different sizes or shapes, the position of the working end of the dial indicator 22 relative to the product 1 under test changes, thereby changing the position of the dial gauge 2 on the product 1 under test, or it can be used to test different products 1 under test. After changing the adjusting element 24 to different sizes, when sliding the dial gauge 2, the adjusting element 24 can keep one side of it in contact with one side wall of the limiting groove 31, so that the dial gauge 2 travels an arc parallel to the limiting groove 31. The adjusting element 24 can also keep both sides of it in contact with both sides of the limiting groove 31, so that the dial gauge 2 travels an arc parallel to the limiting groove 31. These can all be used to check whether the contour of the surface to be tested on the product 1 meets the requirements.

[0032] In addition, the adjusting member 24 can rotate relative to the limiting member 23. When one side surface of the adjusting member 24 is in contact with one side wall of the limiting groove 31, the flush gauge 2 can slide more smoothly in the limiting groove 31.

[0033] It should be noted that, in other embodiments, the limiting members 23 of different sizes may be replaced, and the position detected by the flush gauge 2 may also be changed.

[0034] The specific inspection method of a fixture for inspecting the contour of automotive interior parts in this embodiment is as follows: A contouring simulation block 3 is set on the outer side of the interior part, arranged along the length direction of the interior part. Since the interior part is arc-shaped, the contouring simulation block 3 is also set to be arc-shaped accordingly. A limiting groove 31 is formed on the contouring simulation block 3, arranged along the length direction of the interior part. Before inspection, the surface difference gauge 2 used for inspection is calibrated using a calibration block; during inspection, the calibrated surface difference gauge 2 is slid along the limiting groove 31 so that the working end of the surface difference gauge 2 is in close contact with and slides along the surface to be inspected of the interior part, realizing sliding inspection. This sliding inspection can continuously inspect all points on the entire line on the surface to be inspected, which not only makes the inspection more comprehensive and improves the accuracy of the inspection, but also has extremely high inspection efficiency. If there is a difference between the surface to be tested and the reference surface of the calibration block, the value of the dial indicator 22 will change. If the value of the dial indicator 22 exceeds the preset error range, the contour surface of the product 1 to be tested is qualified. If the value of the dial indicator 22 exceeds the preset error range, that is, it is outside the preset error range, the contour surface of the product 1 to be tested is unqualified.

[0035] During the inspection process, the changes in the value of dial gauge 22 can be observed to determine whether the surface to be inspected of product 1 meets the pre-approved tolerance range. To further improve the accuracy of the inspection, the position of the surface tolerance gauge 2 can be changed by replacing the limit component 23 or the adjustment component 24 with different specifications, which means changing the inspection position of dial gauge 22, thereby further improving the accuracy and effect of the inspection.

[0036] Compared with the prior art, the inspection tool of this embodiment sets a limit groove 31, so that the face difference gauge 2 slides along the limit groove 31 and performs continuous and uninterrupted linear detection on the surface to be inspected of the product 1 to be inspected. The sliding detection method replaces the previous method of multiple fixed-point monitoring, so that all points on a line on the surface to be inspected can be inspected, which improves the accuracy of the detection and solves the problems of low accuracy and low efficiency of the previous detection effect. In addition, the overall structure is simple and compact, and the previous multiple fixed-point detection mechanisms are eliminated, which simplifies the overall structure of the inspection tool, reduces the production cost, and makes the detection operation more convenient and quick. In other embodiments, the position detected by the face difference gauge 2 can be adjusted by replacing the limit members 23 or adjustment members 24 of different specifications, and it has strong applicability.

[0037] Finally, it should be noted that the inspection tool for detecting the contour of an automobile interior trim part disclosed in the embodiment of the present invention is only a preferred embodiment of the present invention and is only used to illustrate the technical solution of the present invention, not to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, it should be understood by those skilled in the art that the technical solutions described in the aforementioned embodiments may be modified or some of the technical features thereof may be replaced by equivalents.
