[0002] A workpiece inspection rack is a reliable tool designed to meet the needs of multi-station operations. It features a modular structure, supporting quick disassembly, assembly, and maintenance upgrades, while also possessing anti-slip properties to ensure operational safety and stability. Functions include multi-station operation, quick tool and fixture changes, and easy portability and storage, significantly improving inspection efficiency. Furthermore, it is manufactured using high-quality materials, ensuring high durability and suitability for harsh working environments. During use, key components such as oil levels, screws, and anchor bolts should be checked regularly to ensure long-term stable operation.

[0003] Existing inspection racks suffer from inconvenience due to insufficient relative displacement and height adjustment, directly affecting the inspection efficiency and quality of processed workpieces. Due to the inconvenient positioning accuracy and imperfect adjustment functions in existing designs, it is difficult to conduct comprehensive and accurate inspections of workpieces during processing, thereby affecting product quality and production efficiency. This problem not only increases inspection costs but may also lead to an increase in rework rates, seriously restricting the overall technical level and competitiveness of the manufacturing industry.

[0004] In response to this technical problem, this application proposes a maintenance rack. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a maintenance rack that significantly improves positioning accuracy and adjustment functions, enhances processing efficiency and workpiece stability, improves workpiece fit during maintenance, ensures precise and efficient operation, and improves maintenance quality and efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A maintenance rack includes a processing table. A fixed platform is fixedly connected to the left end of the processing table. Drive motors are fixedly connected to both the front and rear ends of the inner wall of the processing table. A movable platform is connected to the drive end of the front drive motor via an adjustment group. Extension plates are slidably connected to the inner walls of both the fixed platform and the movable platform. Slide rods are fixedly connected to both the front and rear ends of the left-end extension plate. The inner wall of the right-end extension plate is slidably connected to the outer wall of the slide rod. A clamping platform is fixedly connected to one end of each extension plate. A connecting shell is fixedly connected to one end of each clamping platform. A folding plate is connected to the inner wall of the connecting shell via a bonding group.

[0008] Furthermore, the adjustment assembly includes a transmission rod fixedly connected to the drive end of the rear drive motor, a worm gear slidably connected to the outer wall of the transmission rod, the outer wall of the worm gear rotatably connected to the inner wall of the right-end moving platform, and a screw rod fixedly connected to the drive end of the front drive motor, with the bottom end of the moving platform threadedly connected to the outer wall of the screw rod.

[0009] Furthermore, a worm gear is rotatably connected to the inner wall of the moving platform at the right end, and the outer diameter of the worm gear and the outer diameter of the worm are meshed together.

[0010] Furthermore, a second screw is fixedly connected to the top of the worm gear, and the inner wall of the extension plate at the right end is threaded to the outer wall of the second screw.

[0011] Furthermore, the bonding assembly includes an electric hydraulic cylinder fixedly connected to one of the opposite ends of the connecting shell, an arc-shaped plate one fixedly connected to the driving end of the electric hydraulic cylinder, and an arc-shaped plate two slidably connected to the bottom side of the opposite end of the connecting shell.

[0012] Furthermore, rack plates are fixedly connected to the top of the inner wall of the first arc plate and the bottom of the inner wall of the second arc plate, and transmission gears are rotatably connected to the opposite ends of the connecting shells, with the rack plates and transmission gears being meshed together.

[0013] Furthermore, both the inner walls of the second and first arc-shaped plates are fitted with adapter rods, and the opposite ends of the adapter rods are rotatably connected to the opposite ends of the left and right folding plates.

[0014] Furthermore, adjacent folding plates are rotatably connected by a connecting shaft, with both ends of the middle connecting shaft rotatably connected to the inner wall of the connecting shell.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, starting the front drive motor drives the screw to rotate, which drives the moving table to move within the processing table, so that the clamping table can accurately examine and clamp the workpiece. When starting the rear drive motor, the transmission rod drives the worm and worm wheel, which drives the screw to raise and lower the right extension plate. The slide rod ensures that the extension plates on both sides rise and fall synchronously, realizing the height adjustment of the clamping table. This design significantly improves the positioning accuracy and adjustment function, and enhances the processing efficiency and workpiece stability.

[0017] 2. In this utility model, the starter electric hydraulic cylinder drives the first arc plate to move within the connecting shell. Through the cooperation of the rack plate and the transmission gear, the first arc plate and the second arc plate contract or open relative to each other. At the same time, the adapter rod drives the connecting shaft, and the folding plate follows to form an arc surface or a plane, which closely fits the surface of the workpiece. This design significantly improves the fit of the workpiece during maintenance, ensures precise and efficient operation, and improves maintenance quality and efficiency. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Reference Figures 1-3This utility model provides an embodiment of a maintenance frame, including a processing table 1. A fixed table 3 is fixedly connected to the left end of the processing table 1. Both the front and rear ends of the inner wall of the processing table 1 are fixedly connected to drive motors 9. The drive end of the front drive motor 9 is connected to a moving table 2 via an adjustment group. Extension plates 4 are slidably connected to the inner walls of both the fixed table 3 and the moving table 2. The adjustment group includes a transmission rod 11 fixedly connected to the drive end of the rear drive motor 9. A worm gear 15 is slidably connected to the outer wall of the transmission rod 11. The outer wall of the worm gear 15 is rotatably connected to the inner wall of the right moving table 2. A screw 10 is fixedly connected to the drive end of the front drive motor 9. The bottom end of the moving table 2 is threadedly connected to the outer wall of the screw 10. A worm wheel 16 is rotatably connected to the inner wall of the right moving table 2. The outer diameter of the worm wheel 16 and the outer diameter of the worm gear 15 are meshed. A screw 17 is fixedly connected to the top end of the worm wheel 16. The inner wall of the right extension plate 4 is threadedly connected to the outer wall of the screw 17.

[0028] Specifically: When the front drive motor 9 is started, driving the screw 10 to rotate, the drive motor 9, through the rotation of the screw 10, causes the moving table 2 to move smoothly along the guide rail within the processing table 1. This design facilitates the inspection and adjustment of the clamping table 5 at the moving table 2 and the clamping table 5 at the fixed table 3, thus achieving precise clamping of the workpiece. The design of the inspection frame 7 further enhances the stability of the system. Through its adjustable support structure, it ensures that the moving table 2 will not deviate or vibrate during movement, improving the overall operational reliability. When the rear drive motor 9 is started, the transmission rod 11 is connected to the worm gear 15 through the coupling 12, driving the worm gear 15 to rotate. The rotation of the worm gear 15 further drives the worm wheel 16, which, through a key connection, drives the screw 17 to rotate, causing the right extension plate 4 to rise and fall within the moving table 2. The slide rail 8 in the inspection frame 7 cooperates with the slide rod 6 to ensure that the two extension plates 4 remain synchronized during the rising and falling process. To prevent tilting or damage to the clamping table 5 due to asynchrony, this design not only facilitates height adjustment of the clamping table 5 but also significantly improves positioning accuracy and adjustment capabilities through the precision calibration function of the inspection frame 7. The modular design of the inspection frame 7 also facilitates daily maintenance and repair. Operators can easily check the operating status of key components such as the drive motor 9, transmission rod 11, worm gear 15, worm wheel 16, and screw 17 through the quick-disassembly structure of the inspection frame 7, ensuring long-term stable system operation. Furthermore, the inspection frame 7 is equipped with a lubrication system to periodically lubricate the transmission components, reducing wear and extending equipment lifespan. In summary, through the coordinated work of components such as the drive motor 9, screw 10, transmission rod 11, worm gear 15, worm wheel 16, and screw 17, combined with the precision design and maintenance functions of the inspection frame 7, the entire system achieves efficient and precise clamping and adjustment of workpieces, greatly improving processing efficiency and product quality.

[0029] Reference Figures 4-6The left extension plate 4 has slide rods 6 fixedly connected to both its front and rear ends. The inner wall of the right extension plate 4 is slidably connected to the outer wall of the slide rods 6. Clamping platforms 5 are fixedly connected to opposite ends of the extension plates 4. Connecting shells 8 are fixedly connected to opposite ends of the clamping platforms 5. Folding plates 14 are connected to the inner wall of the connecting shells 8 via a bonding assembly. The bonding assembly includes electric hydraulic cylinders 18 fixedly connected to opposite ends of the connecting shells 8. An arc-shaped plate 7 is fixedly connected to the drive end of the electric hydraulic cylinders 18. An arc-shaped plate 21 is slidably connected to the bottom side of the opposite end of the connecting shells 8. A rack plate 19 is fixedly connected to the top of the inner wall of the first shaped plate 7 and the bottom of the inner wall of the second arc plate 21. A transmission gear 20 is rotatably connected to the opposite end of the connecting shell 8. The rack plate 19 and the transmission gear 20 are meshed. A transition rod 12 is sleeved on the inner wall of the second arc plate 21 and the first arc plate 7. The opposite end of the transition rod 12 is rotatably connected to the opposite end of the left and right folding plates 14. Adjacent folding plates 14 are rotatably connected to each other through a connecting shaft 13. The front and rear ends of the middle connecting shaft 13 are rotatably connected to the inner wall of the connecting shell 8.

[0030] Specifically: When the electric hydraulic cylinder 18 is activated to move the arc-shaped plate 7 within the connecting housing 8, the electric hydraulic cylinder 18, through the extension and retraction of the piston rod, pushes the arc-shaped plate 7 to move smoothly along the guide rail within the connecting housing 8. During this process, the arc-shaped plate 7 achieves precise transmission control through the meshing of its bottom rack plate 19 with the transmission gear 20, allowing the arc-shaped plate 7 and the arc-shaped plate 21 to retract or open relative to each other. The design of the maintenance frame 22 further optimizes this process, as it is equipped with a lubrication system and a limiting device to ensure that the arc-shaped plate 7... The arc-shaped plate 21 and the arc-shaped plate 7 do not jam or shift during movement, improving system stability and service life. Simultaneously, when the arc-shaped plate 21 and the arc-shaped plate 7 move, the connecting shaft 13 rotates via the adapter rod 12, and with the cooperation of the folding plate 14, they retract or expand inwards. The folding plate 14 adopts a hinged connection design, allowing for flexible angle adjustment, enabling the folding plate 14 and the connecting shaft 13 to form an arc-shaped or flat surface, thus closely fitting the workpiece surface. The adjustment mechanism in the maintenance frame 22 further enhances this function, allowing operators to... The unfolding angle and pressure of the folding plate 14 can be precisely controlled via the adjustment knobs on the maintenance rack 22, ensuring optimal fit between the workpiece surface and the maintenance tool. Furthermore, the maintenance rack 22 is equipped with a sensor module that can monitor the movement and pressure distribution of key components such as the arc plate 7, arc plate 21, and folding plate 14 in real time, and provide data feedback to the operator via a display screen for timely adjustment of maintenance parameters. The modular design of the maintenance rack 22 also makes daily maintenance more convenient, allowing operators to quickly disassemble the structure. Easily check the operating status of components such as the electric hydraulic cylinder 18, rack plate 19, transmission gear 20, adapter rod 12, and connecting shaft 13 to ensure long-term stable operation of the system. In summary, through the coordinated work of components such as the electric hydraulic cylinder 18, arc plate 17, rack plate 19, transmission gear 20, arc plate 21, adapter rod 12, connecting shaft 13, and folding plate 14, combined with the precision design and maintenance function of the inspection frame 22, the entire system achieves efficient and precise contact with the workpiece surface, greatly improving the fit and inspection efficiency during workpiece maintenance.

[0031] Working principle: When the front drive motor 9 is started, it drives the screw 10 to rotate, which in turn drives the moving table 2 to move within the processing table 1. This allows the clamping table 5 at the moving table 2 to inspect the clamping table 5 at the fixed table 3, thus clamping the workpiece. When the rear drive motor 9 is started, the transmission rod 11 drives the worm gear 15 to rotate, which in turn drives the worm gear 16 to drive the screw 17, causing the right extension plate 4 to rise and fall within the moving table 2. With the cooperation of the slide rod 6, the extension plates 4 on both sides can also rise and fall, facilitating height adjustment of the clamping table 5 and improving positioning accuracy and adjustment function.

[0032] When the electric hydraulic cylinder 18 is activated to move the arc plate 7 within the connecting housing 8, the arc plate 7, through the cooperation of the rack plate 19 and the transmission gear 20, causes the arc plate 7 and the arc plate 21 to contract or open relative to each other. As the arc plate 21 and the arc plate 7 move, the connecting shaft 13 is driven by the adapter rod 12 and, with the cooperation of the folding plate 14, contracts or opens inward, so that the folding plate 14 and the connecting shaft 13 form an arc-shaped surface or a plane, thereby fitting the workpiece surface and improving the fit of the workpiece during maintenance.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
