Description

Technical Field

[0001] This utility model relates to the field of automotive inspection device technology, specifically a flip-up automotive inspection locking device. Background Technology

[0002] In the automotive manufacturing and repair industry, automotive fixtures are a key process to ensure that the dimensional accuracy, shape accuracy, and assembly accuracy of automotive parts meet design requirements. With the rapid development of the automotive industry, automotive designs are becoming increasingly complex and diverse, and the precision requirements for parts are becoming increasingly stringent. This makes the importance of automotive fixtures in the automotive manufacturing process increasingly prominent. There are many types of automotive parts, covering numerous components of various systems such as engines, chassis, and bodies. These parts not only vary in shape, including regular geometric shapes and complex curved surfaces, but also in size, ranging from small precision parts to large structural components. In the automotive production process, each part needs to be rigorously inspected to ensure that its quality meets standards, thereby ensuring the performance and safety of the entire vehicle.

[0003] However, existing technologies have some drawbacks. Existing locking devices often have limited clamping methods, typically only clamping parts from a fixed direction. For example, common gripper structures can only achieve two- or three-way clamping, making it difficult to stably clamp complex-shaped automotive parts from all angles. This leads to parts easily wobbling during inspection, affecting inspection accuracy. Furthermore, this single clamping method is poorly adaptable to parts of different sizes and shapes, requiring frequent fixture changes or complex adjustments, significantly reducing inspection efficiency. Regarding the part inspection angle, most existing devices cannot achieve flexible part flipping. When multiple sides of a part need to be inspected, it can only be done manually by flipping it over. This is not only cumbersome and labor-intensive, but also prone to causing secondary damage to the part during the flipping process. In addition, manual operation is difficult to guarantee the accuracy of the flipping, which cannot meet the requirements of high-precision inspection. Furthermore, the existing locking device is complicated and inflexible in adjusting the clamping position to expose the surface of the part to be inspected. It often requires disassembling some clamping components or performing complex mechanical operations to change the clamping state of the part to expose the surface to be inspected. This not only wastes time, but also increases the difficulty of operation and the possibility of errors. Utility Model Content

[0004] The purpose of this invention is to provide a flip-up automotive fixture locking device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A flip-up automotive fixture locking device, comprising,

[0007] The base has multiple connecting uprights on its upper surface, a main frame on its upper surface, and a clamping assembly on its upper surface. The clamping assembly includes a gripper component and a platform component. The platform component includes a support frame, which is located on the upper surface of the connecting uprights. A support rotating platform is located at the center of the connecting uprights.

[0008] The gripper component includes two meshing screws, both of which are disposed on the upper surface of the main frame. Each end of the surface of the two meshing screws is engaged with a meshing block. The upper surface of the meshing block is provided with a connecting vertical plate, and one side surface of the connecting vertical plate is provided with a contact plate.

[0009] Furthermore, the interior of the connecting pole is also equipped with an electric turntable for driving the bearing rotating platform to rotate, and the upper surface of the bearing frame is also equipped with four top connecting piles. The side surfaces of the four top connecting piles are all equipped with rotatable limiting plates, and an electric rotating shaft is provided at the connection between the limiting plates and the top connecting piles.

[0010] Furthermore, the upper surface of the main frame is provided with a sliding groove for facilitating the placement of the meshing screws, and the bottom surface of the sliding groove is provided with a sliding secondary groove. The two meshing screws are respectively disposed inside the sliding groove and the sliding secondary groove, and the two meshing screws are arranged in a cross shape. The side surface of the main frame is also provided with two drive motors, and the two drive motors are respectively connected to one end of one meshing screw.

[0011] Furthermore, a sensing pressure plate is provided on one side surface of the contact plate, a central groove is provided on one side surface of the contact plate, a telescopic motor is provided inside the central groove, a movable inner plate is provided at the end of the output shaft of the telescopic motor, and a contact flipping disk is provided on one side surface of the movable inner plate.

[0012] Furthermore, an internal telescopic rod is provided on the inner bottom surface of the central groove, and a slidable movable box is also provided inside the central groove. Multiple sliding side wheels are provided on the side surface of the movable box, and a sliding ramp is provided on the inner side surface of the central groove to facilitate the sliding of the movable box. The internal telescopic rod is located inside the movable box, and an internal sliding block is provided at the end of the output shaft of the internal telescopic rod. An internal sliding groove is provided on the inner upper surface of the movable box to facilitate the sliding of the internal sliding block.

[0013] Furthermore, the upper surface of the contact plate is also provided with a flipping frame, and an electric shaft is provided at the connection between the flipping frame and the contact plate. The bottom surface of the flipping frame is provided with a bottom frame, and a hydraulic rod is provided on the upper surface of the bottom frame. A movable pressure plate is provided at the center of the flipping frame, and the output shaft end of the hydraulic rod is connected to the bottom surface of the movable pressure plate. Connecting support rods are provided on both sides of the flipping frame, and a movable top contact plate is provided at one end of each connecting support rod. Two sliding piles are provided on both sides of the movable top contact plate. Limiting side frames for limiting the sliding piles are provided on both sides of the connecting vertical plate. A bottom bearing block is provided on the bottom surface of the movable top contact plate, and an opening is provided at the center of the connecting vertical plate to facilitate the passage of the bottom bearing block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this solution, by incorporating a gripper component, dynamic and non-destructive switching of the gripping position is achieved during part inspection. When a comprehensive inspection of the side surface of a part is required, the internal telescopic rod pushes the movable box body outward along the sliding ramp to precisely elevate it, forming temporary lateral support for the part. At this time, the drive motor makes a reverse fine adjustment to separate the contact plate from the part, and the sensing pressure plate triggers the flipping frame to automatically rotate 180°. Subsequently, the bottom support block extends to support the weight of the part, and the movable box body retracts to release the side surface. Finally, the movable pressure plate and the bottom support block form an upper and lower clamping. This process can complete the fully automatic conversion from four-sided clamping to upper and lower fixation without manual intervention. It avoids the positioning errors caused by repeated clamping of traditional fixtures and achieves adaptive matching between the clamping force and the shape of the part through the ramp ejection design of the movable box body, significantly improving the efficiency and accuracy of multi-surface inspection of complex parts.

[0016] 2. In this solution, the contradiction between centrifugal force protection and ease of operation during part rotation detection is resolved by incorporating a platform component. The electric turntable built into the platform can achieve 360° continuous rotation. When the part rotates laterally, the limiting plates on the sides of the four top connecting posts rotate synchronously via electric shafts, dynamically forming an adjustable protective barrier along the part's rotation path. This design breaks through the traditional fixed limiting mode of the platform. Through the torque feedback function of the electric shaft, the limiting plates can automatically adjust their opening and closing angles according to the part's size and match the part's centrifugal displacement in real time during rotation, ensuring intelligent matching between protective force and rotation speed. When the part needs to be flipped for inspection, the limiting plates can be completely retracted to be flush with the support frame, providing unobstructed space for the flipping operation of the gripper component.

[0023] Example 1: Please refer to Figures 1 to 4 A flip-up automotive fixture locking device, comprising:

[0024] The base 1 has multiple connecting rods 28 on its upper surface and a main frame 2 on its upper surface.

An electric rotating shaft is provided at the connection between the limiting plate 31 and the top connecting post 30.

[0025] In use, the support frame 6 forms a stable support structure with the base 1 through the connecting uprights 28. The support rotating platform 29 at the center has a built-in electric turntable that can rotate continuously, driving the parts to rotate laterally. When the electric turntable is started, the support rotating platform 29 drives the parts placed on it to rotate. At the same time, the limiting plates 31 on the sides of the four top connecting piles 30 rotate through the electric rotating shaft, forming side guardrails when the parts rotate, preventing the parts from detaching due to centrifugal force during rotation.

[0026] The gripper component includes: two engaging screws 4, both of which are disposed on the upper surface of the main frame 2. The upper surface of the main frame 2 has a sliding groove for facilitating the placement of the engaging screws 4. A sliding auxiliary groove is formed on the bottom surface of the sliding groove. The two engaging screws 4 are respectively disposed inside the sliding groove and the sliding auxiliary groove, forming a cross shape. Two drive motors 3 are also disposed on the side surface of the main frame 2, each connected to one end of an engaging screw 4. Each end of the surface of the two engaging screws 4 engages with a meshing block 5. The upper surface of the meshing block 5... A connecting vertical plate 7 is provided on one side of the connecting vertical plate 7. A contact plate 8 is provided on one side of the contact plate 8. A sensing pressure plate 20 is provided on one side of the contact plate 8. A central groove is formed on one side of the contact plate 8. A telescopic motor 18 is installed inside the central groove. A movable inner plate 17 is provided at the end of the output shaft of the telescopic motor 18. A contact flip plate 19 is provided on one side of the movable inner plate 17. An internal telescopic rod 27 is provided on the bottom surface of the central groove. A slidable movable box 22 is also provided inside the central groove. Multiple sliding side wheels 24 are provided on the side surface of the movable box 22. The inner side surface of the groove is provided with a sliding ramp 23 to facilitate the sliding of the movable box 22. The internal telescopic rod 27 is located inside the movable box 22. The output shaft end of the internal telescopic rod 27 is provided with an internal sliding block 25. The upper inner surface of the movable box 22 is provided with an internal sliding groove 26 to facilitate the sliding of the internal sliding block 25. The upper surface of the contact plate 8 is also provided with a flipping frame 12. An electric shaft is provided at the connection between the flipping frame 12 and the contact plate 8. The bottom surface of the flipping frame 12 is provided with a bottom frame 13. The upper surface of the bottom frame 13 is provided with a hydraulic rod 15. A movable pressure plate 16 is provided at the center of the tilting frame 12. The output shaft end of the hydraulic rod 15 is connected to the bottom surface of the movable pressure plate 16. Connecting support rods 14 are provided on both sides of the tilting frame 12. A movable top contact plate 9 is provided at one end of the connecting support rod 14. Two sliding piles 11 are provided on both sides of the movable top contact plate 9. Restricting side frames 10 for restricting the sliding piles 11 are provided on both sides of the connecting vertical plate 7. A bottom bearing block 21 is provided on the bottom surface of the movable top contact plate 9. An opening is provided at the center of the connecting vertical plate 7 to facilitate the passage of the bottom bearing block 21.

[0027] In use, two drive motors 3 drive two meshing screws 4 to rotate, thereby controlling the four meshing blocks 5 to move synchronously closer to or further away. When clamping automotive repair parts, the two drive motors 3 drive simultaneously, causing the four meshing blocks 5 to move inwards simultaneously, clamping the parts in four directions. At this time, the sensing pressure plates 20 on the side surfaces of the four contact plates 8 are all pressed. During this clamping process, the side surfaces of the parts are blocked. When it is necessary to repair the four side surfaces of the parts, the internal telescopic rods 27 inside the four movable boxes 22 extend, causing the movable boxes 22 to slide upwards along the sliding ramp 23. At this time, due to the slope of the sliding ramp 23, the movable boxes 22 gradually push outwards and fit against the side surfaces of the parts. At this time, the two drive motors 3 rotate in opposite directions, causing the four meshing blocks 5 to move slightly in the opposite direction, causing the contact plates 8 to gradually move away from the surface of the parts. At this time, the sensing pressure plates 20 lose their contact effect and send a signal. At this time, the parts... All four side surfaces are clamped by the top contact of the movable box 22. Subsequently, after receiving the signal sent by the induction pressure plate 20, the electric shaft at the connection between the flipping frame 12 and the contact plate 8 drives the flipping frame 12 to flip 180 degrees. At this time, due to the connection effect of the connecting support rod 14, the moving top contact plate 9 will move closer to the connecting vertical plate 7 as the flipping frame 12 flips. During this process, the sliding pile 11 slides inside the restricting side frame 10. Finally, after the moving top contact plate 9 reaches the position closest to the connecting vertical plate 7, the bottom bearing block 21 will also extend and be located on the bottom surface of the part. At this time, the internal telescopic rod 27 retracts, causing the four movable boxes 22 to gradually lose the clamping effect with the side surfaces of the part. At this time, the bottom surface of the part is supported by the bottom bearing block 21. At this time, the hydraulic rod 15 extends, driving the movable pressure plate 16 to move downward and contact the upper surface of the part. The movable pressure plate 16 and the bottom bearing block 21 clamp the part in the vertical direction, exposing the four side surfaces of the part, thereby achieving the effect of adjusting the clamping position.

[0028] Working principle:

[0029] When the equipment is working, the platform component and the gripper component on the base 1 work together to clamp and flip the parts for inspection. In the platform component, the support frame 6 is stably connected to the base 1 through the connecting rod 28. The support rotating table 29 has a built-in electric turntable, which can drive the parts to rotate continuously in the horizontal direction. When rotating, the limiting plates 31 on the sides of the four top connecting piles 30 rotate through the electric rotating shaft to form side guardrails to prevent the parts from falling off due to centrifugal force.

[0030] When the gripper assembly is working, the two drive motors 3 drive the two interlocking screws 4, which are in a cross-shaped state, to rotate, causing the four interlocking blocks 5 to move synchronously. During initial clamping, the four interlocking blocks 5 move inward, and the sensing pressure plate 20 on the side of the contact plate 8 is pressed, thus achieving four-sided clamping of the part. When the side surface of the part needs to be inspected, the internal telescopic rods 27 inside the four movable boxes 22 extend, driving the movable boxes 22 to push outward along the sliding ramp 23 and fit against the side surface of the part. At this time, the drive motor 3 makes a reverse fine adjustment to move the contact plate 8 away from the part, and the sensing pressure plate 20 sends a signal. The electric shaft drives the tilting frame 12 to rotate 180°, moves the top contact plate 9 close to the connecting vertical plate 7, and the bottom bearing block 21 extends to receive the part. The internal telescopic rods 27 retract to release the part from the movable box 22. Finally, the hydraulic rod 15 pushes the movable pressure plate 16 and the bottom bearing block 21 to clamp the part from top to bottom, exposing the four side surfaces and completing the clamping position adjustment.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
