DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0032] Please refer to Figures 1-8 An embodiment provided by the application:

[0033] The motor 22 used in the application is a product that can be directly purchased in the market, and its principle and connection mode are all prior art known by a person of ordinary skill in the art, so they will not be described here.

[0034] A flexible automotive exterior trim matching integrated inspection fixture includes a base plate 1, a testing platform 11 at the top of the base plate 1, and a testing base 12 on the surface of the testing platform 11. Through holes are formed on the inner sides of both the base plate 1 and the testing platform 11, and a pressure rod 13 is movably disposed within each through hole. A pressing mechanism is provided on the surface of the base plate 1, and a locking mechanism is provided on the inner side of the base plate 1. An auxiliary mechanism is provided on the surface of the testing platform 11. The pressing mechanism includes positive and negative screws 21, which are disposed at the top of the base plate 1, and a moving block 23 is threadedly connected to the surface of the positive and negative screws 21. A connecting rod is fixedly connected to the lower surface of the testing platform 11. The connecting rod 28 and the locking mechanism include a connecting block 34, which is movable inside the base plate 1. The surface of the pressure rod 13 is provided with a slot 35. The auxiliary mechanism includes a first magnet 4, which is fixedly connected to the upper surface of the testing platform 11. The surface of the pressure rod 13 is fixedly connected to a second magnet 41, and the lower surface of the testing base 12 is fixedly connected to a third magnet 43. The testing platform 11 can support and place the testing base 12. By placing the car exterior trim inside the testing base 12 and pressing it with the pressure rod 13, the car exterior trim can be measured.

[0035] Furthermore, the pressing mechanism also includes a first fixed block 2, which is fixedly connected to the upper surface of the base plate 1. The positive and negative screws 21 are movable inside the first fixed block 2. A motor 22 is fixedly installed on the surface of the first fixed block 2, and the output ends of the positive and negative screws 21 and the motor 22 are fixedly connected. The positive and negative screws 21 are arranged in two sets, and the moving blocks 23 are arranged in two sets and movably connected to the positive and negative screws 21. By rotating the positive and negative screws 21, the moving blocks 23 can move under the action of the positive and negative screws 21, and squeeze or release the squeeze on the roller 211. By squeezing the roller 211 by the moving blocks 23, the connecting rod 28 can drive the detection table 11 to move upward, and make the automotive exterior inside the detection base 12 contact the lower surface of the pressure rod 13, so as to facilitate the pressing of the automotive exterior by the pressure rod 13 to ensure stable detection of the automotive exterior.

[0036] Furthermore, a limiting block 24 is fixedly connected to the lower surface of the movable block 23, and a limiting groove 25 is opened on the inner side of the base plate 1. The limiting blocks 24 are in four groups and are correspondingly connected to the movable block 23. The end of the limiting block 24 away from the movable block 23 moves inside the limiting groove 25. Through the cooperation of the limiting block 24 and the limiting groove 25, the movable block 23 can be limited, which can prevent the movable block 23 from shifting under the action of the positive and negative screws 21. This facilitates the stable movement of the movable block 23 and realizes the squeezing of the roller 211, so that the connecting rod 28 can drive the detection table 11 to move vertically.

[0037] Furthermore, a support plate 26 is fixedly connected to the upper surface of the base plate 1, and a connecting plate 27 is fixedly connected to the top of the support plate 26. The connecting rod 28 is movable inside the connecting plate 27, and a second fixing block 29 is fixedly connected to the lower surface of the connecting rod 28. A third fixing block 210 is fixedly connected to the lower surface of the second fixing block 29, and a roller 211 is movably connected to the inner side of the third fixing block 210. By setting the connecting plate 27, the connecting rod 28 can be limited, so that when the moving block 23 moves, the connecting rod 28 can move vertically under the action of the moving block 23, and drive the testing table 11 to move up and down, so that the car exterior and the pressure rod 13 can contact each other and press the car exterior.

[0038] Furthermore, the roller 211 is movably connected to the third fixed block 210 via a rotating shaft, and the connecting rod 28 is fixedly connected to the detection table 11 in four groups. A spring 212 is fixedly connected to the surface of the connecting rod 28, and the two ends of the spring 212 are fixedly connected to the connecting plate 27 and the second fixed block 29 respectively. The surface of the positive and negative screws 21 is movably connected to the first transmission belt 213. Both groups of positive and negative screws 21 are movably connected to the first transmission belt 213 via pulleys. By setting the spring 212, the second fixed block 29 can be reset, thereby enabling the connecting rod 28 to drive the detection table 11 to reset as well. This allows the moving block 23 to release the pressure on the roller 211, enabling the detection table 11 to drive the detection base 12 to reset.

[0039] Furthermore, the locking mechanism also includes a movable groove 3, which is located on the inner side of the base plate 1. A threaded rod 31 is movably connected to the inner side of the movable groove 3. A sleeve rod 32 is threadedly connected to the surface of the threaded rod 31, and a fixed rod 33 is fixedly connected to the surface of the sleeve rod 32. Through the setting of the sleeve rod 32, the rotation of the threaded rod 31 can drive the sleeve rod 32 to move, thereby enabling the fixed rod 33 to drive the connecting block 34 to move inside the movable groove 3. This allows the connecting block 34 to engage and disengage with the slot 35, facilitating the locking and unlocking of the pressure rod 13, and enabling the pressure rod 13 to be flexibly assembled and disassembled.

[0040] Furthermore, the sleeve rod 32, the fixed rod 33, and the connecting block 34 are all movable inside the movable groove 3, and the threaded rod 31 is movably connected to the base plate 1, while the connecting block 34 is fixedly connected to the fixed rod 33. The surface of the threaded rod 31 is movably connected to the second transmission belt 36. Through the setting of the fixed rod 33 and the connecting block 34, the fixed rod 33 drives the connecting block 34 to move, which can realize the insertion and separation of the connecting block 34 and the slot 35, thereby realizing the fixing and unfixing of the pressure rod 13. By fixing the pressure rod 13, it is easy for the pressure rod 13 to stably press the automotive exterior. By unfixing, it is easy to remove or assemble the pressure rod 13, so that the position of the pressure rod 13 can be adjusted and installed according to the needs of measuring the automotive exterior.

[0041] Furthermore, one end of the second transmission belt 36 is movably connected to the positive and negative screws 21 via a pulley, and the other end of the second transmission belt 36 is movably connected to the threaded rod 31 via a pulley. By setting the second transmission belt 36, when the positive and negative screws 21 rotate, the positive and negative screws 21 can drive the second transmission belt 36, thereby enabling the threaded rod 31 to rotate and causing the sleeve rod 32 to drive the fixed rod 33 and the connecting block 34 to move.

[0042] Furthermore, the first magnets 4 are evenly distributed on the testing platform 11, and the first magnets 4 correspond to the through holes. The lower surface of the testing base 12 is fixedly connected to a positioning rod 42, and the positioning rod 42 is movable inside the through hole. By setting the positioning rod 42, when installing the testing base 12, the positioning rod 42 is passed through the through hole, which can realize the positioning of the installation of the testing base 12. With the adsorption effect of the first magnet 4 and the third magnet 43, the testing base 12 can be installed on the testing platform 11, which is convenient for the construction of the testing base 12 and also convenient for the interchangeability of the testing base 12, so as to realize the matching of the testing base 12 with the automotive exterior.

[0043] Working principle: During use, the car exterior is placed inside the testing base 12. The motor 22 is electrically connected to an external power source. The operator starts the motor 22 by pressing the switch. The motor 22 drives the positive and negative screws 21 to rotate. The moving block 23 is limited by the limiting block 24 and the limiting groove 25, and will move under the action of the positive and negative screws 21. This causes the limiting block 24 to move inside the limiting groove 25. Consequently, the roller 211 is squeezed by the moving block 23 and will roll. This causes the second fixed block 29 to drive the connecting rod 28 to move upward, realizing the connection. The connecting rod 28 moves inside the connecting plate 27. At this time, the spring 212 is in a contracted state, which enables the detection platform 11 to drive the detection base 12 to move vertically upward, and makes the car exterior inside the detection base 12 contact the pressure rod 13, thereby achieving the pressure rod 13 to press the car exterior. Through the reverse rotation of the positive and negative screws 21, the moving block 23 moves and cancels the squeezing of the roller 211. Then, the second fixed block 29 is reset under the rebound action of the spring 212. Then, the connecting rod 28 drives the detection platform 11 and the detection base 12 to descend, thereby achieving the reset.

[0044] When the forward and reverse screws 21 rotate, the first transmission belt 213 moves and drives the threaded rod 31, causing the threaded rod 31 to rotate. Under the action of the threaded rod 31, the sleeve 32 moves inside the movable groove 3, driving the fixed rod 33 and the connecting block 34 to move accordingly. The connecting block 34 moves into the slot 35, locking the pressure rod 13. Thus, the pressure rod 13 is locked during the upward movement of the testing table 11, ensuring the stable pressing of the pressure rod 13 onto the automotive exterior. When the forward and reverse screws 21 rotate in the opposite direction, causing the testing table 11 and the testing base 12 to descend, the sleeve 32 moves in the opposite direction, driving the fixed rod 33 and the connecting block 34 to move accordingly. This separates the connecting block 34 from the slot 35, thus canceling the locking of the pressure rod 13, allowing the pressure rod 13 to be removed, adjusted, or assembled.

[0045] The attraction between the first magnet 4 and the second magnet 41 allows the pressure rod 13 to pass through the through hole, enabling the initial assembly of the pressure rod 13 onto the detection base 12. The pressure rod 13 can be assembled in different positions. The positioning rod 42 is inserted into the through hole when the detection base 12 is placed on the detection table 11 to position the installation of the detection base 12. Combined with the attraction between the first magnet 4 and the third magnet 43, the assembly of the detection base 12 is achieved. The detection base 12 can also be replaced by separating the first magnet 4 and the third magnet 43.

[0046] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, using the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
