Description

Technical Field

[0001] This utility model relates to the field of automotive interiors, specifically a small-plane fixed-point detection device for automotive interiors. Background Technology

[0002] With the rapid development of the automotive industry, especially the rapid development of new energy vehicles, people have increasingly higher requirements for car interiors.

[0003] Some accessories on automotive interior parts, such as interior door handle trims, are usually made with rounded surfaces to achieve a decorative effect. At the same time, in order to save space, the outer surface of the interior door handle trims is made relatively small. In order to ensure product matching requirements, there are also testing requirements for such small flat surfaces.

[0004] Currently, using inspection gauges or coordinate measuring machines (CMMs) for large-point inspection is problematic because the surface dimensions are relatively small and predominantly curved. Using ordinary inspection gauges results in significant measurement deviations and poor dimensional repeatability. If CMMs are used, each inspection takes a considerable amount of time and is expensive. Utility Model Content

[0005] To achieve the above objectives, the present invention aims to provide a small-plane fixed-point inspection device for automotive interior surfaces. This addresses the problem of poor repeatability when using ordinary inspection gauges for products requiring small-plane measurement. The main issue is that the gauge rarely measures precisely at the same point on the product each time, and the placement of the gauge on the reference surface can also be inaccurate. This product achieves precise positioning of the inspection point and the gauge itself by adding a positioning device for the gauge. The inspection needle is also adjustable and fixed to the gauge, and a reference zero-point correction is added to the gauge. The product utilizes a small inspection platform, and the handheld dedicated gauge can be used on-site, achieving convenient and rapid inspection. The present invention provides the following technical solution:

[0006] A device for fixed-point inspection of small flat surfaces in automotive interior trim includes a measuring ruler, a measuring point base, a rotating bracket, and a testing platform. The measuring ruler includes a zero-point calibration block, an irregularly shaped measuring ruler, a knob, and a measuring needle. The knob is slidably mounted on the irregularly shaped measuring ruler, and the measuring needle is fixed on the knob. A digital display component is installed on the irregularly shaped measuring ruler. The measuring point base is provided with a groove for inserting the measuring ruler. The rotating bracket is slidably mounted on the testing platform. Both the measuring ruler and the measuring point base are fixed on the testing platform, and a lower pressure block is also installed on the testing platform. An upper pressure block is installed on the rotating bracket. A measuring ruler is a handheld dimensional measuring ruler with a digital display. It mainly consists of a non-circular measuring ruler, a knob, and a measuring probe. The non-circular measuring ruler is the main body of the ruler and has a digital display similar to that of calipers. The knob can move laterally on the non-circular measuring ruler, and the measuring probe is fixed in a specific lateral position by the knob. This lateral position is determined by the distance between the product's inspection point and the measuring point base. The measuring point base is a reference for precise positioning of product points. It has a groove whose size matches the end size of the measuring ruler, allowing the measuring ruler to be inserted into the groove. The measuring ruler is inserted into the groove of the measuring point base, and the measuring probe... The probe will fall on the product's inspection point, and the product's dimensions can be measured by the digital display of the inspection ruler. Interior handle trim pieces are the products targeted for inspection by this device. After the product is installed on the lower pressure block, the upper pressure block presses down, thereby fixing and positioning the product. The lower pressure block is fixed on the inspection table and is used to install the product for inspection, fixing and positioning the product together with the upper pressure block. The rotating bracket is used to install the upper pressure block and is fixed on the inspection table itself. The rotating bracket rotates on its axis, simultaneously causing the upper pressure block to flip up and down, thus achieving the purpose of quick product installation and removal. The zero-position calibration block is used to calibrate the inspection ruler to zero position before product inspection. The working process of this product is as follows: First, place the irregular-shaped measuring ruler into the groove of the zero-position calibration block, move the measuring needle horizontally to align the measuring needle with the designated point, and then rotate the knob to lock the position of the measuring needle; set the dimension on the irregular-shaped measuring ruler to zero; this completes the calibration of the measuring ruler; then flip the upper pressure block open, and place the interior handle trim to be tested on the lower pressure block; then flip the upper pressure block closed, and at the same time rotate the upper locking knob to fix the interior handle trim; next, insert the head of the measuring ruler into the groove of the measuring point seat, and read the measurement value on the measuring ruler to complete the test; after all the test points are completed, open the upper pressure block and take out the interior handle trim.

[0007] As a further embodiment of this utility model: the zero-position calibration block is designed with a detection ruler insertion slot, and the zero-position calibration block is also designed with a stepped plane for calibrating the height of the detection needle. When the irregular-shaped detection ruler is inserted into the detection ruler insertion slot, the detection needle touches the stepped plane, which is the designed detection zero point. After the irregular-shaped detection ruler is zeroed, product testing can be carried out.

[0008] As a further embodiment of this utility model: the irregular-shaped measuring ruler is provided with horizontal ribs for mounting the knob and the measuring needle, so as to facilitate the movement of the measuring needle and the knob.

[0009] As a further embodiment of this utility model: the groove is a rectangular groove, which is easy to insert and has good connection.

[0010] As a further embodiment of this utility model, both the upper and lower pressure blocks are made of nylon material, which has a mature manufacturing process, long service life, and low cost.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This product features a grooved measuring point holder, ensuring measurements are taken at the same location each time, thus improving repeatability. Furthermore, by locking the relative positions of each measuring point on the holder and ensuring consistency with the zero-position calibration block, testing efficiency and accuracy are enhanced. The adjustable measuring point distance of the measuring ruler, combined with locking the position of the measuring probe after calibration, improves testing effectiveness, simplifies product testing procedures, and makes the product easy to use. It enables rapid testing on the production floor and reduces testing costs. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] This product features a small testing platform on which a rotating bracket, a measuring scale, and a zero-point calibration block are mounted for convenient production, handling, and use. A measuring point holder is added to the lower pressure block, featuring a rectangular groove. This groove allows the end of the measuring scale to be inserted, locating the measuring point and resolving the issue of uncertain scale position. The measuring point holder should be directly below the product's measurement point, with the center of each groove aligned with the product's measurement point. This simplifies the measurement process, allowing the measuring scale to be calibrated only once to measure all points, improving testing efficiency. The measuring scale includes a zero-point calibration block, a measuring probe, a knob, and a caliper display. The zero-point calibration block also features a grooved positioning base corresponding to the product's measurement point dimensions, used to calibrate the measuring point position of the measuring scale and the product's surface difference reference position before use. After calibration, the measuring probe is fixed and locked to establish the testing origin. The upper and lower pressure blocks are used to fix the product in a square shape. The upper pressure block is designed with a flipping mechanism to facilitate quick loading and unloading of the product and make it easy to operate.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] See Figures 1-7A device for fixed-point detection of small flat surfaces in automotive interiors includes a detection ruler 1, a measuring point seat 2, a rotating bracket 5, and a detection platform 6. The detection ruler 1 includes a zero-position calibration block 11, an irregularly shaped detection ruler 8, a knob 9, and a detection needle 10. The knob 9 is slidably mounted on the irregularly shaped detection ruler 8, and the detection needle 10 is fixed on the knob 9. A digital display component is installed on the irregularly shaped detection ruler 8. The measuring point seat 2 is provided with a groove for inserting the detection ruler 1. The rotating bracket 5 is slidably mounted on the detection platform 6. Both the detection ruler 1 and the measuring point seat 2 are fixed on the detection platform 6, and a lower pressure block 7 is also installed on the detection platform 6. An upper pressure block 4 is installed on the rotating bracket 5. The measuring ruler 1 is a handheld measuring ruler with a digital display. It mainly consists of a non-circular measuring ruler 8, a knob 9, and a measuring needle 10. The non-circular measuring ruler 8 is the main body of the measuring ruler 1, and it has a digital display component similar to that of calipers. The knob 9 can move laterally on the non-circular measuring ruler 8, and the measuring needle 10 is fixed in a certain lateral position by the knob 9. This lateral position is determined based on the distance between the product's inspection point and the measuring point base 2. The measuring point base 2 is a testing reference for designing precise point positions on the product. It has a groove with the same size as the end size of the measuring ruler 1, allowing the measuring ruler 1 to be inserted into the groove. The measuring ruler 1 is inserted into the groove of the measuring point base 2, and the measuring needle 10 on the measuring ruler 1... The product dimensions can be measured by the digital display of the measuring ruler 1, which is placed on the product inspection point. The interior handle trim 3 is the product to be inspected by this device. After the interior handle trim 3 is installed on the lower pressure block 7, the upper pressure block 4 presses down, thereby fixing and positioning the product. The lower pressure block 7 is fixed on the inspection table 6 and is used to install the interior handle trim 3. Together with the upper pressure block 4, it fixes and positions the interior handle trim 3. The rotating bracket 5 is used to install the upper pressure block 4. It is fixed on the inspection table 6. The rotating bracket 5 rotates on its axis, which drives the upper pressure block 4 to flip up and down, thus achieving the purpose of quick product installation and removal. The zero-position calibration block 11 is used to perform zero-position calibration on the measuring ruler 1 before product inspection. The working process of this product is as follows: First, the irregular-shaped measuring ruler 8 is placed in the groove of the zero-position calibration block 11. The measuring needle 10 is moved laterally to align the measuring needle 10 with the designated point. Then, the knob 9 is rotated to lock the position of the measuring needle 10. The dimension on the irregular-shaped measuring ruler 8 is set to zero. This completes the calibration of the measuring ruler 1. Then, the upper pressure block 4 is flipped open, and the interior handle trim 3 to be tested is placed on the lower pressure block 7. The upper pressure block 4 is flipped closed, and the upper locking knob is rotated to fix the interior handle trim 3. Next, the head of the measuring ruler 1 is inserted into the groove of the measuring point seat 2, and the measurement value on the measuring ruler 1 is read to complete the test. After all the test points are completed, the upper pressure block 4 is opened, and the interior handle trim 3 is taken out.

[0025] In one embodiment of this utility model, the zero-position calibration block 11 is designed with a detection ruler insertion slot, and the zero-position calibration block 11 is also designed with a stepped plane for calibrating the height of the detection needle 10. When the irregular detection ruler 8 is inserted into the detection ruler insertion slot, the detection needle 10 abuts against the stepped plane, which is the designed detection zero point. After the irregular detection ruler 8 is zeroed, product testing can be performed.

[0026] In one embodiment of this utility model, the irregular-shaped detection ruler 8 is provided with a horizontal rib for mounting the knob 9 and the detection needle 10, so as to facilitate the movement of the detection needle 10 and the knob 9.

[0027] In one embodiment of this utility model, the groove is a rectangular groove, which facilitates insertion and provides a strong connection.

[0028] In one embodiment of this utility model, both the upper pressure block 4 and the lower pressure block 7 are made of nylon material, which has a mature manufacturing process, long service life, and low cost.
