Description

Technical Field

[0001] This utility model relates to the field of mechanical automation devices, specifically a workpiece flipping and positioning device. Background Technology

[0002] In industrial production, traditional methods for handling workpieces requiring flipping and pressing rely heavily on manual operation. Operators must manually clamp the workpieces to flip them and then use simple tools for pressing. This method has significant drawbacks: firstly, manual operation is extremely inefficient, with each flipping and pressing process taking a long time, making it difficult to meet the demands of large-scale production; secondly, during manual handling and pressing, the weight, size, and operating force of the workpieces are difficult to control precisely, easily leading to workpiece drops, injuries, and other safety accidents, posing serious safety hazards. Furthermore, manual operation makes it difficult to ensure consistent pressing force and position each time, resulting in inconsistent product quality and a high scrap rate. With the trend towards automation and intelligentization in industrial production, traditional manual operation methods can no longer meet the requirements of modern manufacturing for efficient, safe, and precise production, necessitating automated equipment to solve these problems.

[0003] Therefore, those skilled in the art have provided a workpiece flipping and positioning device to solve the problems mentioned in the background art. Utility Model Content

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

[0015] This utility model provides an automated workpiece flipping and pressing device that achieves efficient, safe, and precise production through multi-component collaborative design. First, a linear guide rail and servo motor drive a sliding plate, which in turn drives a single-cylinder gripper to move stably up and down. Combined with a drive motor, coupling, and reducer, the single-cylinder gripper completes a precise 0-180 degree flip, significantly improving flipping efficiency and accuracy compared to manual operation and avoiding the uncertainties of manual flipping. Second, an electric telescopic rod drives a slide table to slide back and forth along the guide rail, quickly positioning the pressure plate directly above the workpiece. A second electric hydraulic cylinder drives the pressure plate up and down along a guide rod to complete the pressing. The cooperation between the guide rod and the sliding sleeve ensures a smooth pressing process, guaranteeing consistency in pressing position and force, effectively improving product quality. Third, the pallet is detachable via bolts, allowing for quick replacement to accommodate different workpiece specifications, enhancing the equipment's versatility. A first electric hydraulic cylinder drives a support column to move up and down, providing stable support for the flipped workpiece, further ensuring the safety and reliability of the pressing process. The entire device replaces manual operation with automation, significantly improving production efficiency, reducing safety risks, and achieving standardized and automated production of workpiece flipping and pressing.

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.

[0022] Example 1

[0023] Reference Figures 1-4 This embodiment provides a workpiece flipping and positioning device, including a worktable 1. A bracket 2 is fixedly installed on the upper end of the worktable 1. Linear guide rails 8 are fixedly installed on both sides of the bracket 2 near the front end. Slide plates 9 are slidably connected to the linear guide rails 8. Horizontal plates 10 are fixedly connected to the front ends of the slide plates 9 on both sides. A single-cylinder gripper 12 is provided at the front end of the horizontal plate 10. The linear guide rails 8 are controlled by a servo motor to drive the slide plates 9 to slide up and down along the linear guide rails 8, thereby driving the horizontal plate 10 and the single-cylinder gripper 12 to move up and down. A top plate 7 is fixedly installed on the top of the bracket 2. Two slide rails 13 are provided on the top plate 7. A slide table 14 is slidably connected to the slide rails 13. A support plate 3 is fixedly installed on the upper end of the worktable 1 in front of the bracket 2. A tray 4 is detachably installed on the upper end of the support plate 3 by bolts. A positioning pin for positioning is threaded on the tray 4. The tray 4 is detachably connected to the support plate 3 by bolts, which facilitates the replacement of trays of different specifications to adapt to different workpieces.

[0024] Furthermore, a drive motor 11 is fixedly installed at the rear end of the horizontal plate 10. The output shaft of the drive motor 11 is fixedly connected to the single-cylinder gripper 12 through a coupling and a reducer. The drive motor 11 drives the single-cylinder gripper 12 to perform a 0-180 degree flipping motion.

[0025] Example 2

[0026] Reference Figures 1-4 This embodiment is based on the previous embodiment, but differs in that the tray 4 has a through hole in the center, and a support column 5 is installed in the through hole; an electric hydraulic cylinder 6 is fixedly installed at the lower end of the worktable 1 directly below the tray 4, and the piston rod of the electric hydraulic cylinder 6 is fixedly connected to the support column 5. Through the extension and retraction of the piston rod of the electric hydraulic cylinder 6, the support column 5 is driven to move up and down through the through hole of the tray 4 to support the workpiece after it is flipped.

[0027] Furthermore, an electric telescopic rod 18 is fixedly installed on the upper end of the top plate 7 behind the slide table 14. The piston rod of the electric telescopic rod 18 is fixedly connected to the slide table 14. The extension and retraction of the piston rod of the electric telescopic rod 18 drives the slide table 14 to slide back and forth along the slide rail 13. An electric hydraulic cylinder 15 is fixedly installed on the slide table 14 near the front end. A through groove 19 is opened on the top plate 7 directly below the electric hydraulic cylinder 15. The piston rod of the electric hydraulic cylinder 15 passes through the slide table 14. The pressure plate 16 extends below the slide table 14 and is fixedly connected. The piston rod of the second electric hydraulic cylinder 15 moves the pressure plate 16 up and down along the guide rod 17. The guide rod 17 is fixedly connected to the upper end of the pressure plate 16 near the four corners. The top of the guide rod 17 extends through to the top of the slide table 14 and is fixedly connected to the limiting block. The guide rod 17 and the slide table 14 are slidably connected by a sliding sleeve. The guide rod 17 and the slide table 14 are slidably connected by a sliding sleeve, which guides and limits the up and down movement of the pressure plate 16.

[0028] Working Principle: Initially, the workpiece is placed on tray 4 and precisely positioned using threaded locating pins. Next, a servo motor drives linear guide 8, causing slide plate 9 and connected horizontal plate 10 to move downwards, bringing single-cylinder gripper 12 to the workpiece clamping position. The single-cylinder gripper 12 then closes to clamp the workpiece. Subsequently, electric telescopic rod 18 is activated, its piston rod extending to slide slide 14 forward along slide rail 13, moving electric hydraulic cylinder 15 and pressure plate 16 mounted on slide 14 directly above the workpiece. At this time, the piston rod of electric hydraulic cylinder 15 extends downwards, causing pressure plate 16 to move downwards along guide rod 17, performing the initial pressing of the workpiece through through slot 19 on top plate 7. The sliding fit between guide rod 17 and sliding sleeve ensures that pressure plate 16 presses down vertically, and limit blocks prevent excessive displacement of guide rod 17. After the initial pressing is completed, electric hydraulic cylinder 15 resets pressure plate 16, and electric telescopic rod 18 retracts slide 14. Next, the servo motor controls the linear guide rail 8 again, driving the single-cylinder gripper 12 to rise to the designated position. The drive motor 11 drives the single-cylinder gripper 12 to rotate through the coupling and reducer, realizing the workpiece rotation. After rotation, the electric hydraulic cylinder 6 is activated, and its piston rod extends to drive the support column 5 to rise through the through hole of the tray 4, supporting the rotated workpiece. Subsequently, the electric telescopic rod 18 and the electric hydraulic cylinder 15 are activated again, causing the pressure plate 16 to perform a secondary pressing of the workpiece, thereby completing the overall pressing process of the upper and lower ends of the workpiece.
