Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts inspection platform, specifically to a reconfigurable automotive bracket parts inspection platform. Background Technology

[0002] In the automotive parts manufacturing industry, bracket-type parts (such as chassis brackets, interior brackets, powertrain brackets, etc.) are key structural components connecting the vehicle body and functional modules. Their dimensional accuracy, such as hole tolerances and assembly surface flatness, directly affects the assembly stability and operational safety of the entire vehicle. As the core inspection carrier in the mass production of bracket-type parts, the inspection platform needs to accurately match the structural features of the parts to complete the rapid qualification judgment.

[0003] Traditional bracket-type component inspection platforms typically employ inspection and positioning structures (such as inspection pins and contour positioning blocks) that are welded to the platform body or connected via bolts. Their positions and quantities are perfectly suited to a single component size. When inspecting bracket components with different hole layouts and contour dimensions, the platform body must be re-drilled, re-welded, or completely replaced. This not only results in a long modification cycle (usually 2-5 days) but also prevents the restoration of the original inspection functionality. Consequently, the inspection platform can only cover 1-2 component sizes. For production lines with numerous derivative models and rapid component iteration, dozens of inspection platforms need to be stockpiled, leading to an equipment idle rate exceeding 60% and significantly increasing manufacturing and management costs. Therefore, we propose a reconfigurable automotive bracket-type component inspection platform. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Please see Figures 1-5This utility model provides a technical solution: a reconfigurable automotive bracket parts inspection platform, including a base plate 1. Cylinders 11 for clamping parts are provided on both the left and right sides of the base plate 1. A rear side plate 2 is fixedly installed on the rear side plate of the base plate 1. The rear side plate 2 has multiple through holes 20. Multiple limiting discs 22 concentrically arranged with the through holes 20 are fixedly installed on the front side of the rear side plate 2. Multiple cards 23 arranged in a ring at equal intervals are fixedly installed on the front side of the limiting discs 22. A snap-fit ​​gap 231 is provided between adjacent cards 23. An inspection tool assembly plate 3 is provided on the front side of the rear side plate 2. The rear end of the fixture assembly plate 3 is detachably fitted with a perforated plate 32. Multiple locking blocks 33 arranged in a ring at equal intervals are fixedly installed on the rear side of the perforated plate 32. The locking blocks 33 engage with the locking gap 231. A stud 34 is fixedly installed at the center of the rear side of the perforated plate 32. The stud 34 passes through the limiting plate 22 and the through hole 20 and is fixed with a nut 36. This allows the fixture assembly plate 3 to be quickly positioned by the locking blocks 33 and the locking gap 231, and fixed with the stud 34 and the nut 36. It can be replaced or adjusted without modifying the platform body, adapting to the inspection of different specifications of bracket parts, reducing equipment idle rate and cost.

[0019] In this embodiment, vertical plates 10 are fixedly installed on both the left and right sides of the base plate 1, and cylinder 11 is fixedly installed on the corresponding vertical plates 10, so that the vertical plates 10 can provide stable support for cylinder 11, avoid the cylinder 11 from being affected by force deviation when clamping parts, and ensure the structural stability of cylinder 11 when working.

[0020] like Figure 1 As shown, a rectangular plate 12 is fixedly installed at the end of the telescopic shaft of the cylinder 11. A clamping plate 13 is detachably installed on the side of the rectangular plate 12 by multiple fastening bolts, so that the clamping plate 13 can be quickly disassembled and assembled through the rectangular plate 12. This facilitates the replacement of the appropriate clamping plate 13 according to the clamping requirements of different bracket parts, thereby improving the adaptability and flexibility of the clamping structure.

[0021] like Figure 1 As shown, a rubber pad 131 is fixedly installed on the side of the clamping plate 13. The thickness of the rubber pad 131 is between 6mm and 10mm. When the clamping plate 13 clamps the part, the rubber pad 131 can buffer the clamping force, avoid scratches on the surface of the part or deformation due to excessive clamping, ensure the integrity of the part before inspection, and ensure the accuracy of the inspection results.

[0022] like Figure 1As shown, side support rods 21 are fixedly installed between the two end plates of the rear side plate 2 and the bottom plate 1. The rear side plate 2, the bottom plate 1 and the side support rods 21 form a triangular structure. The stability of the triangle is used to enhance the stability of the connection between the rear side plate 2 and the bottom plate 1, and to prevent the rear side plate 2 from tilting due to force during the installation of the inspection fixture assembly plate 3 or during the inspection process, so as to ensure the positioning accuracy of the inspection structure.

[0023] Specifically, a center hole 221 is provided at the center of the limiting plate 22, and the stud 34 passes through the center hole 221, so that the stud 34 can accurately pass through the limiting plate 22 along the center hole 221, and avoid the stud 34 from being misaligned during installation.

[0024] Furthermore, a fixing plate 31 is fixedly installed at the rear end of the fixture assembly plate 3. The fixing plate 31 is detachably installed on the front side of the perforated plate 32 by multiple fastening bolts, so that the fixture assembly plate 3 can be quickly connected or separated from the perforated plate 32 through the fixing plate 31, simplifying the installation process of the fixture assembly plate 3 and improving the replacement efficiency of the fixture assembly plate 3.

[0025] In addition, the fixture assembly plate 3 is provided with multiple assembly holes 30, which facilitate the installation of different testing components. An elastic washer 35 is fitted on the stud 34, and the nut 36 presses the elastic washer 35 against the rear side of the rear plate 2. The elastic washer 35 can enhance the anti-loosening effect of the nut 36, prevent the stud 34 from loosening due to vibration during the testing process, and ensure the fixed stability of the fixture assembly plate 3.

[0026] It is worth noting that since there are multiple through holes 20 and limiting plates 22, the fixture assembly plate 3 can be installed on the corresponding limiting plate 22 to achieve overall reconstruction and assembly. In addition, since the locking block 33 engages with the locking gap 231, the angle of the fixture assembly plate 3 can be adjusted by rotating the perforated plate 32 when needed. As long as the locking block 33 can still be engaged with the locking gap 231, the nut 36 can be used to fix it. The assembly holes 30 on the fixture assembly plate 3 are circular and elongated elliptical, which allows the corresponding fixtures to be fixedly installed on the fixture assembly plate 3 by bolts or other means as needed to achieve the assembly effect.

[0027] Finally, it should be noted that the cylinder 11, the corresponding air source, the control system, and the external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0028] When using the reconfigurable automotive bracket parts inspection platform of this utility model, according to the specifications of the bracket parts to be inspected, the rear end fixing plate 31 of the inspection plate assembly plate 3 is connected to the perforated plate 32 by fastening bolts. After rotating the perforated plate 32 to adjust the angle, the locking block 33 of the perforated plate 32 is inserted into the locking gap 231 of the corresponding limiting plate 22 of the rear side plate 2. The stud 34 is passed through the center hole 221 and the through hole 20, the elastic washer 35 is put on and the nut 36 is tightened to fix it. The matching inspection component is installed through the assembly hole 30 of the inspection plate assembly plate 3. Start the cylinders 11 on the vertical plates 10 on both sides of the base plate 1, adjust the telescopic shaft according to the size of the part, so that the clamping plate 13 on the rectangular plate 12 is close to the part, and the part is clamped by the rubber pad 131 to avoid damage. The operation of the inspection component completes the inspection of the hole position and flatness of the part; after the inspection, the cylinder 11 resets and releases the part. If it is necessary to change the inspection specification, unscrew the nut 36 to adjust the position or angle of the fixture assembly plate 3, and then reinstall the corresponding fixture.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
