Description

Technical Field

[0001] This utility model relates to the field of automotive processing equipment, and in particular to a gravity-sensing-based automatic flipping detection mechanism for large automotive sheet metal applications. Background Technology

[0002] In the production of automotive parts, product inspection is of paramount importance. To ensure that product dimensions and quality are within the tolerances of technical standards and to guarantee the quality of product assembly, products at every stage must undergo rigorous and meticulous inspection. This is especially true in the aerospace industry, where the precision requirements for parts are extremely high. Any minute deviation can affect the overall assembly and performance; therefore, comprehensive dimensional inspection and quality control are crucial for both safety and performance. Currently, the use of tooling and fixtures for inspection often requires flipping the product or manually lifting the fixture blocks to achieve comprehensive inspection. However, for large automotive parts, relying on manual operation is not only inefficient, labor-intensive, time-consuming, and labor-intensive, but also poses certain safety hazards. Manual flipping can lead to product deformation and damage due to improper operation, and even injury to operators. Utility Model Content

[0003] In view of the above problems, the purpose of this utility model is to provide an automatic flip detection mechanism, and a labor-saving and safe mechanism based on gravity sensing for automatic flip detection.

[0004] To achieve the above objectives, this utility model provides a gravity-sensing automatic flip detection mechanism, which includes a U-shaped seat on a frame, L-shaped connecting arms extending to both sides inside the U-shaped seat, a connecting pin penetrating the U-shaped seat and the L-shaped connecting arms at one end of the U-shaped seat, a connecting short arm at one end of the L-shaped connecting arms, an L-shaped detection block at the other end of the L-shaped connecting arms, a gravity block on the connecting short arm, and a locking structure on both sides of the U-shaped seat to press and fix the L-shaped connecting arms.

[0005] In some embodiments, the locking structure includes bolts respectively provided on both sides of the U-shaped seat, and an umbrella-shaped block threaded onto the bolts to press down and fix the L-shaped connecting long arm.

[0006] In some implementations, three of each are provided: a U-shaped seat, an L-shaped connecting long arm, a connecting short arm, a gravity block, and an L-shaped detection block.

[0007] In some implementations, the gravity block is cylindrical in shape and made of cast iron HT250 with a surface coated with anti-rust paint.

[0008] In some embodiments, the three gravity blocks are respectively: a base diameter of 130mm, a height of 380mm, and a weight of 38.93kg; a base diameter of 130mm, a height of 240mm, and a weight of 24.77kg; and a base diameter of 130mm, a height of 240mm, and a weight of 24.77kg. The weights of the gravity blocks used are calculated based on the lever principle: the expression is F1×L1=F2×L2.

[0009] In some embodiments, the length of the L-shaped connecting long arm is 280 mm; the length of the connecting short arm is 129 mm.

[0010] In some embodiments, the weights of the three L-shaped detection blocks are 11.41 kg, 11.41 kg, and 17.94 kg, respectively.

[0011] The beneficial effects of this utility model are automatic flipping detection, labor-saving, and safety. Due to the size characteristics of large product inspection fixtures, previous methods required considerable force to raise / lower the inspection block. The improved structure considers the even distribution of measurement areas, with each area equipped with an independent gravity block and an L-shaped inspection block. Through gravity sensing and lever balance principles, the inspection block is automatically flipped upwards / downwards. Previous methods generally used single-sided locking, which, while convenient, posed certain safety hazards. This invention utilizes the principle of gravity block lever balance, combined with locking mechanisms on both sides, to ensure accurate positioning and left-right balance of the L-shaped inspection block. Furthermore, the left and right locking mechanisms must open or close simultaneously to secure the lever connecting arm during flipping, ensuring safety. This solves the problem of flipping detection in large automotive parts, enabling automatic workpiece flipping, improving inspection efficiency, reducing labor intensity, and lowering safety risks. It achieves automatic flipping detection, labor-saving, and safety benefits. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0013] The utility model will now be described in further detail with reference to the accompanying drawings.

[0014] like Figure 1As shown, a gravity-sensing automatic flipping detection mechanism includes a U-shaped base 2 on a frame 1, L-shaped connecting arms 3 extending to both sides within the U-shaped base 2, a connecting pin 4 penetrating the U-shaped base 2 and the L-shaped connecting arms 3 at one end of the U-shaped base 2, a connecting short arm 5 at one end of the L-shaped connecting arms 3, an L-shaped detection block 6 at the other end, a gravity block 7 on the connecting short arm 5, and locking structures 8 on both sides of the U-shaped base 2 for pressing and fixing the L-shaped connecting arms 3. The locking structure 8 includes bolts 81 on both sides of the U-shaped base 2, and umbrella-shaped blocks 82 threaded onto the bolts 81 for pressing and fixing the L-shaped connecting arms 3 downwards. When placing a part for measurement, the locking structure must be tightened simultaneously to press the connecting arms together, thereby accurately positioning the L-shaped detection block 6 at the measurement point. When removing parts, this design reduces the workload of inspectors and prevents the L-shaped inspection block 6 from suddenly popping up due to operator negligence or improper operation, thus avoiding potential safety hazards. Furthermore, the design of opening two locking mechanisms separately allows operators to release the locking devices gradually and systematically, further reducing the possibility of accidents. Three of each of the following are provided: U-shaped base 2, L-shaped connecting long arm 3, connecting short arm 5, gravity block 7, and L-shaped inspection block 6. The gravity block 7 is cylindrical, made of cast iron HT250, and coated with anti-rust paint. The three gravity blocks 7 have the following dimensions: base diameter 130mm, height 380mm, weight 38.93kg; base diameter 130mm, height 240mm, weight 24.77kg; and base diameter 130mm, height 240mm, weight 24.77kg. The weights mentioned above are calculated based on the lever principle: the expression is F1×L1=F2×L2, which are used to calculate the weights of the gravity blocks 7. The length of the L-shaped connecting long arm 3 is 280mm; the length of the connecting short arm 5 is 129mm. The weights of the three L-shaped detection blocks 6 are 11.41kg, 11.41kg, and 17.94kg, respectively.

[0015] In application, by adding a gravity block 7 to the fixture, the principle of gravity sensing and lever balance is utilized to achieve automatic flipping of the fixture block, reducing the operational difficulty for inspectors and ensuring the accuracy and reliability of product measurement. The operating trajectory and landing point of the flipping mechanism are also considered, making the fixture operation more convenient and simple, and effectively preventing potential personnel injury. During part measurement, the L-shaped fixture block 6 can lock the part for measurement when flipped downwards. Similarly, when the locking device is released, the upper gravity block 7 automatically senses and descends, causing the L-shaped fixture block 6 to automatically spring back up, improving operational convenience and reducing the time for placing and switching parts by two-thirds. Manual efficiency is significantly improved. Operators do not need to exert effort to lift these components, reducing operational difficulty and allowing for easy part handling. This design not only reduces the labor intensity of operators but also avoids safety hazards caused by improper force. This provides a reference solution for the flipping inspection of large parts in the automotive and aerospace equipment manufacturing industries.
