Description

Technical Field

[0001] The utility model belongs to the technical field of flatness detection, and particularly relates to a sheet metal flatness detection mechanism for automobile sheet metal repair. Background Technique

[0002] Automobile sheet metal repair is a technology used to repair damages to the automobile body. It mainly aims at body depressions, deformations and damages caused by vehicle collisions, scratches, impacts, etc. Through automobile sheet metal repair, the original shape and structure of the vehicle body can be restored to ensure the appearance and safety of the vehicle. Sheet metal flatness detection is an important step in evaluating whether the surface of the vehicle body has returned to the original flat state after automobile sheet metal repair. Through sheet metal flatness detection, it can be ensured that the surface of the repaired area has no ripples, depressions or uneven places, thus guaranteeing the beauty and structural integrity of the vehicle body.

[0003] At present, there are some flatness detection devices on the market. For example, a device for detecting the flatness of a sheet metal surface is disclosed on the Chinese Patent Network, and its publication number is CN217818632U. This flatness detection device can adapt to the flatness detection of rectangular sheet metals of different sizes, but there are some defects and deficiencies to be improved: (1) Some existing flatness detection devices lack a leveling structure. When the detection device is placed on an uneven ground, it is difficult to level effectively, thus reducing the accuracy of the sheet metal flatness detection result and easily generating detection errors; (2) When some existing flatness detection devices are performing flatness detection, it is difficult to effectively block external light. When the external light is relatively strong, it will interfere with the flatness detection process, thus affecting the detection accuracy; (3) After some existing flatness detection devices complete the detection, it is necessary to manually sort and collect qualified and unqualified products.

[0033] Please refer to Figure 1-8As shown in the figure, a sheet metal flatness detection mechanism for automobile sheet metal repair of the present utility model includes a base 1. At the four corners of the bottom of the base 1, there are fixedly connected with screw cylinders 2. The screw cylinders 2 are cylindrical, with internal threads engraved on their inner walls, and a leveling component is installed in each screw cylinder 2. On the top of the base 1, there are fixedly connected with two pairs of roller frames 3. On each pair of roller frames 3, there is installed a motor 4. On the output shaft of the motor 4, there is installed a conveyor roller 5. The conveyor rollers 5 are respectively located between each pair of roller frames 3, and a conveyor belt 6 is drivingly connected between the two conveyor rollers 5. By driving the motor 4, the conveyor roller 5 can be driven to rotate. After the conveyor roller 5 rotates, it can drive the conveyor belt 6 to move, so as to move the body sheet metal parts to be detected to the detection position. At both ends of the conveyor belt 6, there are sorting boxes 7. The sorting boxes 7 are placed on the base 1. The sorting boxes 7 can respectively place the qualified products and unqualified products after detection. By controlling the moving direction of the conveyor belt 6, the qualified products and unqualified products can be respectively introduced into the corresponding sorting boxes 7 according to the detection results, without manual sorting, saving time and effort, and greatly improving the work efficiency. On the top of the base 1, there is fixedly connected with a light shielding plate 8. The side of the light shielding plate 8 is in an n shape and is located directly above the conveyor belt 6. During detection, the light shielding plate 8 can effectively block external light, thus effectively avoiding interference with the flatness detection process when the light is relatively strong and affecting the detection accuracy. A detection component is installed on the light shielding plate 8;

[0034] The leveling component includes a leveling rod 9. The diameter of the leveling rod 9 is equal to the inner diameter of the screw cylinder 2. The surface of its rod body is engraved with external threads matching the screw cylinder 2, and a foot pad 10 is fixedly connected to the bottom end of the leveling rod 9. By means of threaded connection, the leveling rod 9 together with the foot pad 10 can be fixed at the bottom of each screw cylinder 2. When the foot pad 10 contacts the ground, it can support the base 1. When the base 1 is placed on an uneven ground, the screwing depth of the leveling rod 9 in each screw cylinder 2 can be adjusted respectively to level the base 1 until the base 1 is horizontal, thereby ensuring the accuracy of the sheet metal flatness detection result and avoiding detection errors;

[0035] The detection component includes a cylinder 11, which is installed on the top of the light-shielding plate 8. The bottom end of its output shaft is fixedly connected with a mounting plate 12. A detection element 13 is installed at the bottom of the mounting plate 12. The detection element 13 can be a commercially available sheet metal flatness detection instrument such as a laser measuring instrument. During detection, the detection element 13 scans the surface of the vehicle body sheet metal part. The detection element 13 records the height data of each point on the surface and generates a large number of data points to record the change of the surface height. Then the measurement data is transmitted to a computer or other data processing devices, and a special software is used to generate a three-dimensional contour map or a planar graph from the data points, so as to visually display the surface flatness. After that, the measurement result is compared with a predetermined flatness standard or tolerance to evaluate the quality of the sheet metal surface, so as to distinguish qualified products from unqualified products. By driving the cylinder 11, the mounting plate 12 together with the detection element 13 can be moved up and down to adjust the detection height of the detection element 13 at any time according to the size of the vehicle body sheet metal part, so that the detection element 13 can fully scan the entire vehicle body sheet metal part.

[0036] Wherein, a layer of anti-slip pad 14 is arranged on the bottom surface of the foot pad 10. The surface of the anti-slip pad 14 is engraved with diamond-shaped anti-slip patterns. The anti-slip pad 14 can be made of an elastic material such as rubber and is fixed by means of glue adhesion. When the foot pad 10 contacts the ground, the anti-slip pad 14 can be used to increase the friction between the foot pad 10 and the ground to play an anti-slip role, so as to prevent the detection mechanism from slipping and displacing during the detection process.

[0037] Wherein, a plurality of mounting rods 15 are fixedly connected to the bottom of the mounting plate 12. External threads are engraved on the rod bodies of the mounting rods 15, and a nut 16 matching with each mounting rod 15 is threadedly connected to each mounting rod 15. A plurality of mounting holes 17 are formed in the detection element 13. The number of the mounting holes 17 is the same as that of the mounting rods 15, and the diameters are equal. The center of each mounting hole 17 corresponds to the center of each mounting rod 15 one by one. Each mounting rod 15 can be aligned with and pass through the corresponding mounting hole 17. At this time, the nut 16 is threadedly connected to each mounting rod 15 and tightened, and the detection element 13 can be installed and fixed through the mutual cooperation among the mounting rods 15, the mounting holes 17 and the nuts 16. By unscrewing the nut 16, the detection element 13 can be removed for debugging and replacement of the detection element 13.

[0038] Wherein, a pair of baffle plates 18 are arranged inside the light-shielding plate 8. The baffle plates 18 are respectively located above the front side and the rear side of the conveyor belt 6 and are flush with the edge of the conveyor belt 6. A plurality of fixing rods 19 are fixedly connected between the baffle plates 18 and the inner wall of the light-shielding plate 8. When the conveyor belt 6 drives the vehicle body sheet metal part to move, the baffle plates 18 can play a role of limiting and guiding to prevent the vehicle body sheet metal part from shifting in position and falling off the conveyor belt 6 during the moving process.

[0039] Among them, a protective pad 20 is provided on the surface of the baffle 18 close to the conveyor belt 6. The protective pad 20 can be made of elastic materials such as sponge and is fixed by means of glue adhesion. The protective pad 20 can play a role in anti-abrasion protection to prevent the body sheet metal from directly contacting the surface of the baffle 18 and causing collision and wear.

[0040] Among them, the sorting box 7 is located below the conveyor belt 6. A handle 21 is fixedly connected to its outer wall, and a pair of guide blocks 22 are fixedly connected to the bottom of the sorting box 7. A pair of guide grooves 23 are provided on the top surface of the base 1. Both the guide grooves 23 and the guide blocks 22 are rectangular, and their widths are correspondingly equal. The center of each guide groove 23 corresponds to the center of each guide block 22 one by one. When the sorting box 7 is placed on the base 1, the guide blocks 22 can be aligned and fitted into the corresponding guide grooves 23. At this time, the mutual cooperation between the guide blocks 22 and the guide grooves 23 can quickly guide and position the sorting box 7 to prevent the position of the sorting box 7 from shifting.

[0041] Among them, a buffer assembly is provided in the sorting box 7. The buffer assembly includes a buffer plate 24. A plurality of springs 25 are fixedly connected between the bottom of the buffer plate 24 and the inner wall of the bottom of the sorting box 7. A plurality of buffer blocks 26 are provided on the top surface of the buffer plate 24. The buffer blocks 26 are linearly distributed at equal intervals along the length and width directions of the buffer plate 24. The buffer blocks 26 can be made of materials such as hemispherical silica gel and are fixed by means of glue adhesion. When the body sheet metal that has passed the detection is imported from the conveyor belt 6 into the sorting box 7, it will first contact the buffer plate 24. At this time, the buffer blocks 26 can play a role in buffer protection to prevent the body sheet metal from being collided and worn after falling.

[0042] The circuits, electronic components and chip modules involved in the present utility model are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve improvements to software and methods.

[0043] The standard parts used in the application documents can be purchased from the market. All the components in the application documents can be customized according to the records in the specification and drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets and welding that are mature in the prior art. The machines, parts and equipment all adopt conventional models in the prior art. The electrical components described in this article are all electrically connected to the external main controller and 220V mains electricity, and the main controller can be a conventional known device such as the LED lamp body for control.

[0044] The working principle of the present utility model is:

[0045] When the utility model is in use, the detection mechanism can be placed on the ground for use. The leveling rod 9 and the foot pad 10 can be fixed to the bottom of each threaded cylinder 2 by means of threaded connection. When the foot pad 10 contacts the ground, it can support the base 1. When the base 1 is placed on an uneven ground, the screwing depth of the leveling rod 9 in each threaded cylinder 2 can be adjusted respectively to level the base 1 until the base 1 is horizontal, thus ensuring the accuracy of the detection result of the sheet metal flatness, avoiding detection errors. When it is necessary to detect the flatness of the body sheet metal after the automotive sheet metal is repaired, first place the body sheet metal on the conveyor belt 6, and then drive the motor 4 to drive the conveyor roller 5 to rotate. After the conveyor roller 5 rotates, it can drive the conveyor belt 6 to move until the body sheet metal is moved below the detection element 13, and then stop moving. Then let the detection element 13 scan the surface of the body sheet metal. The detection element 13 will record the height data of each point on the surface and generate a large number of data points to record the change of the surface height. Then the measurement data is transmitted to a computer or other data processing devices, and a special software is used to generate a three-dimensional contour map or a plan view from the data points, so as to visually display the surface flatness. Then the measurement result is compared with a predetermined flatness standard or tolerance to evaluate the quality of the sheet metal surface, so as to distinguish qualified products and unqualified products. A light-shielding plate 8 is arranged directly above the conveyor belt 6. During the detection, the light-shielding plate 8 can effectively block the external light, thus effectively avoiding the interference of strong light on the flatness detection process and affecting the detection accuracy. If the detection result is qualified, the motor 4 is driven again and the qualified products are introduced into the sorting box 7 at one end through the conveyor belt 6. If the detection result is unqualified, the motor 4 is driven in the reverse direction and the unqualified products are introduced into the sorting box 7 at the other end through the conveyor belt 6. Thus, the qualified products and unqualified products can be respectively introduced into the corresponding sorting boxes 7 by controlling the moving direction of the conveyor belt 6, without manual sorting, saving time and effort and greatly improving the work efficiency.
