Description

Technical Field

[0001] This utility model relates to the field of gripping device technology, and more specifically, to a mechanical automated gripping device. Background Technology

[0002] Automation refers to the process by which machines or devices operate or are controlled automatically according to predetermined programs or instructions without human intervention. Mechanical automation, specifically, is the process by which machines or devices achieve automated control through mechanical means. The realization of mechanical automation has led mechanical production into a new era. Through automatic control systems, it has truly enabled large-scale industrial production, reduced labor intensity, and increased labor efficiency, elevating the global production level to a new level. In the field of mechanical automation, mechanized automatic gripping devices are quite common. These devices mainly consist of mechanical grippers and robotic arms, capable of precisely gripping objects and replacing manual labor.

[0003] Current automated mechanical gripping devices have limited gripping structure opening angles, only able to unfold to a fixed angle. Therefore, when gripping items of different sizes, the gripping structure needs to be changed, reducing the device's practicality. In addition, when gripping smooth items, the gripping structure is prone to shaking or shifting due to the weight of the smooth items themselves, causing the items to fall and be damaged.

Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0023] Example:

[0024] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0025] Please see Figure 1-2 This utility model provides a technical solution: a mechanical automated gripping device, including a fixing bar 1, on which two ring sleeves 5 are movably sleeved. Grooves 6 are formed on both sides of the bottom of the fixing bar 1, and a single dual-axis motor 7 passes between the two grooves 6. Screws 8 are fixedly connected to the two output shafts of the dual-axis motor 7. One end of each screw 8 is rotatably connected to a bearing fixed to one side of the inner wall of each groove 6 via a rotating shaft. Second nuts 9 are threaded onto each screw 8, and the bottoms of the two second nuts 9 are fixedly connected to the bottom of the inner wall of each ring sleeve 5. Through the combined action of the fixing bar 1, ring sleeves 5, dual-axis motor 7, and screws 8, the position of the two fixing plates 10 can be easily adjusted, making it suitable for gripping items of different sizes without needing to change the gripper structure. This improves the practicality of the device. The bottom of each of the two rings 5 ​​is fixedly connected to a fixing plate 10. Each of the two fixing plates 10 is equipped with a hydraulic rod 14. One end of each of the two hydraulic rods 14 is fixedly connected to a cavity plate 15. One side of each of the two cavity plates 15 is fixedly connected to a miniature vacuum pump 18. One side of each of the two cavity plates 15 is equipped with a three-way pipe 19. One end of each of the two three-way pipes 19 is connected to the suction end of each of the two miniature vacuum pumps 18. The two ends of each of the two three-way pipes 19 are respectively equipped with a first solenoid valve 20 and a second solenoid valve 21. Through the combined action of the cavity plate 15, the miniature vacuum pump 18, the three-way pipe 19, the first solenoid valve 20 and the second solenoid valve 21, after clamping the item, the cavity plate 15 can be evacuated to a vacuum state, so that the vacuum negative pressure attracts the item, thereby improving the clamping stability of the corresponding item.

[0026] Specifically, a sleeve 2 is fixedly connected to the top of the fixing strip 1, and a U-shaped stud 3 is movably inserted through the sleeve 2. Both ends of the U-shaped stud 3 are threaded with a first nut 4. Limiting strips 17 are movably inserted through the two fixing plates 10, and one end of the two limiting strips 17 is fixedly connected to the top of the two cavity plates 15 respectively.

[0027] By adopting the above technical solution, the sleeve, U-shaped stud 3 and first nut 4 facilitate the installation of the device with the robotic arm, and the setting of the limit strip 17 improves the stability of the cavity plate 15.

[0028] Specifically, a support plate 11 is fixedly connected to one side of each of the two fixed plates 10, a telescopic rod 13 is fixedly connected to one side of each of the two support plates 11, a limit plate 12 is fixedly connected to both ends of the fixed strip 1, one end of each of the two telescopic rods 13 is fixedly connected to one side of each of the two limit plates 12, and rubber pads 16 are fixedly connected to the opposite sides of each of the two cavity plates 15.

[0029] By adopting the above technical solution, the load-bearing stability of the fixing strip 1 can be improved by setting the support plate 11 and the telescopic rod 13, and the friction between the items can be increased by setting the rubber pad 16, and the sealing effect of the cavity plate 15 can be improved.

[0030] The working principle of this utility model is as follows: When in use, the sleeve 2 is fitted onto the robotic arm, the U-shaped stud 3 passes through the sleeve 2, and is fixed by the first nut 4 to complete the installation of the device. The device is then connected to an external power supply and control equipment. When grabbing an item, the size of the item is compared, and the position of the fixing plate 10 is adjusted. The output shaft of the dual-axis motor 7 drives the screw 8 to rotate, causing the second nut 9 to move along the screw 8. The second nut 9 drives the ring sleeve 5 to move along the fixing strip 1. The ring sleeve 5 drives the position of the fixing plate 10 to move. Then the device can be lowered to both sides of the item. The hydraulic rod 14 extends and pushes the cavity plate 15 to move. The rubber pad 16 on one side of the cavity plate 15 tightly presses against the item, clamping the item and completing the grabbing of the item.

[0031] When gripping a smooth object, after the cavity plate 15 clamps the smooth object, the second solenoid valve 21 closes, the first solenoid valve 20 opens, and the miniature vacuum pump 18 works to expel the air between the cavity plate 15 and the smooth object, making it a vacuum state. Then the first solenoid valve 20 closes, the miniature negative pressure pump stops working, and the vacuum negative pressure state inside the cavity plate 15 attracts the smooth object, improving the stability of gripping the smooth object. When the object is released, the second solenoid valve 21 opens to release pressure through the three-way pipe 19, and then the hydraulic rod 14 retracts, causing the cavity plate 15 to separate from the object.

[0032] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
