Description

Technical Field

[0001] This utility model relates to the field of gripping device technology, and in particular to an adjustable upright gripping device. Background Technology

[0002] Vertical gripping devices are gripping equipment used in the field of mechanical automation, mainly for gripping, transporting and other operations on objects.

[0003] However, in existing technologies, most gripping devices adopt a fixed structure design with a lack of or a single adjustment mechanism. They can only achieve position adjustment by moving the entire robotic arm, and cannot make localized and precise adjustments based on the size and shape of the object. The transmission method is mostly manual or simple motor drive, lacking closed-loop feedback control, resulting in low adjustment accuracy and easy position deviation. The rigid connection of each component in the structure lacks buffering and adaptive mechanisms. When gripping irregularly shaped objects, uneven force can easily cause the object to slip or the device to be damaged. At the same time, the fixed frame layout limits the gripping range. When facing complex working conditions (such as densely stacked or irregularly placed objects), it is difficult to quickly find a suitable gripping point. Moreover, the structure is prone to loosening due to stress concentration during long-term operation, further reducing stability and gripping efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the prior art where gripping devices typically have fixed structures, making it difficult to adapt to the gripping needs of objects of different sizes and shapes, lacking sufficient adjustment flexibility and precision, having low gripping efficiency under complex working conditions, and having structural stability that needs to be improved, thus failing to meet the diverse industrial gripping scenarios. Therefore, an adjustable vertical gripping device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable vertical gripping device, comprising a rectangular frame, a mechanical arm joint fixedly connected to one side of the rectangular frame, an adjustment mechanism fixedly installed on one edge of the rectangular frame, the adjustment mechanism comprising a positioning plate, a second guide rail and an adjustment block, the positioning plate being fixedly installed on the lower surface at the corner of the rectangular frame, the second guide rail being fixedly installed inside the positioning plate, a slider being fixedly connected to one side of the adjustment block, the slider being slidably connected to the second guide rail, and the adjustment block being located on both sides of the rectangular frame.

[0006] Preferably, a reinforcing plate is fixedly installed on one side of the positioning plate, and an extension plate is fixedly installed at the end of the second guide rail.

[0007] Preferably, a second servo motor is fixedly installed at the end of the extension plate, and a lead screw is fixedly connected to the output end of the second servo motor.

[0008] Preferably, one end of the lead screw is rotatably connected to the reinforcing plate, and a transmission block is threaded onto the outer wall of the lead screw, with the transmission block being fixedly connected to the adjusting block.

[0009] Preferably, a limit block is fixedly installed on the lower surface at the center of the rectangular frame, and a first servo motor is fixedly installed on one side of the limit block.

[0010] Preferably, the first servo motor and the second servo motor are perpendicular to each other and have the same structure, and a connecting block is threaded onto the outer wall of the lead screw at the end of the first servo motor.

[0011] Preferably, a first guide rail is fixedly installed on the lower surface of the rectangular frame edge, and a clamping plate is slidably connected to the lower surface of the first guide rail. The clamping plate and the positioning plate are symmetrically arranged, and the clamping plate is fixedly connected to the connecting block.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, in the adjustment mechanism, the positioning plate is fixed to the lower surface of the corner of the rectangular frame, the second guide rail is installed inside the positioning plate, and the slider on one side of the adjustment block slides with the second guide rail, so that the adjustment block can move along the guide rail. The change of the position of the adjustment blocks on both sides of the rectangular frame can adapt to different gripping needs, so that the device can flexibly adjust the gripping range and position according to the size and shape of the gripped object, thereby improving the applicability and flexibility of the device.

[0014] 2. In this utility model, the first servo motor adjusts the position of the clamping plate through a lead screw drive and connecting block. In conjunction with the adjustment mechanism, it adjusts the position of the gripping component from different directions, forming a three-dimensional adjustment system with the adjustment mechanism. This further improves the adaptability of the gripping device to objects of different shapes and sizes. The clamping plate and the positioning plate are symmetrically arranged, making the force on the gripping device more balanced and the gripping more stable, thus enhancing the reliability and safety of the gripping operation.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an adjustable vertical gripping device, including a rectangular frame 1. A robotic arm joint 3 is fixedly connected to one side of the rectangular frame 1. An adjustment mechanism 2 is fixedly installed on one edge of the rectangular frame 1. The adjustment mechanism 2 includes a positioning plate 21, a second guide rail 22, and an adjustment block 23. The positioning plate 21 is fixedly installed on the lower surface at the corner of the rectangular frame 1. The second guide rail 22 is fixedly installed inside the positioning plate 21. A slider 24 is fixedly connected to one side of the adjustment block 23. The slider 24 is slidably connected to the second guide rail 22. The adjustment block 23 is located on both sides of the rectangular frame 1. A reinforcing plate 27 is fixedly installed on one side of the positioning plate 21. An extension plate 25 is fixedly installed at the end of the second guide rail 22. A second servo motor 26 is fixedly installed at the end of the extension plate 25. A lead screw is fixedly connected to the output end of the second servo motor 26. One end of the lead screw is rotatably connected to the reinforcing plate 27. A transmission block 28 is threadedly connected to the outer wall of the lead screw. The transmission block 28 is fixedly connected to the adjustment block 23.

[0023] The specific setup and function of this embodiment are described below. The rectangular frame 1 is connected to the robotic arm via a robotic arm joint 3 on one side. In the adjustment mechanism 2, a positioning plate 21 is fixed to the lower surface of the corner of the rectangular frame 1. A second guide rail 22 is installed inside the positioning plate 21. A slider 24 on one side of the adjustment block 23 slides along the second guide rail 22, allowing the adjustment block 23 to move along the guide rail. A second servo motor 26 is installed at the end of the extension plate 25. Its output screw passes through the transmission block 28 and is rotatably connected to the reinforcing plate 27. When the second servo motor 26 starts, the screw rotates, driving the threaded transmission block 28 to move along the screw. Because the transmission block 28 is fixedly connected to the adjustment block 23, it drives the adjustment block 23 to move along the second guide rail via the slider 24. The guide rail 22 slides, allowing the position of the adjustment blocks 23 on both sides of the rectangular frame 1 to change, in order to adapt to different gripping needs. During use, the position of the positioning plate 21 remains stationary, serving as the main support point for gripping. Through the cooperation of the second servo motor 26, lead screw, transmission block 28, slider 24 and the second guide rail 22 in the adjustment mechanism 2, the position of the adjustment block 23 can be adjusted precisely and conveniently, enabling the device to flexibly adjust the gripping range and position according to the size and shape of the object being gripped, thus improving the applicability and flexibility of the device. The positioning plate 21, reinforcing plate 27 and extension plate 25 enhance the structural stability of the adjustment mechanism 2, ensuring a smooth and reliable adjustment process. The connection between the robotic arm joint 3 and the rectangular frame 1 allows the device to be adapted to different robotic arms.

[0024] Example 2: Figure 2 and Figure 4 As shown, a limiting block 5 is fixedly installed on the lower surface of the center of the rectangular frame 1. A first servo motor 6 is fixedly installed on one side of the limiting block 5. The first servo motor 6 and the second servo motor 26 are perpendicular to each other and have the same structure. A connecting block 7 is threaded onto the outer wall of the lead screw at the end of the first servo motor 6. A first guide rail 4 is fixedly installed on the lower surface of the edge of the rectangular frame 1. A clamping plate 8 is slidably connected to the lower surface of the first guide rail 4. The clamping plate 8 and the positioning plate 21 are symmetrically arranged, and the clamping plate 8 is fixedly connected to the connecting block 7.

[0025] The overall effect of this embodiment is that the limiting block 5 on the lower surface of the center of the rectangular frame 1 provides a mounting base for the first servo motor 6. The first servo motor 6 is perpendicular to and has the same structure as the second servo motor 26. When the lead screw at its end rotates, the connecting block 7, which is threaded to the lead screw, moves along the lead screw. The first guide rail 4 on the lower surface of the edge of the rectangular frame 1 provides a sliding track for the clamping plate 8. The clamping plate 8 is fixedly connected to the connecting block 7 and is also slidably connected to the first guide rail 4 through two other sliders 24. Therefore, the movement of the connecting block 7 will cause the clamping plate 8 to slide on the lower surface of the first guide rail 4. Thus, the first servo motor 6 is driven by the lead screw. The connecting block 7 and the adjusting mechanism 2 are used to adjust the position of the gripping plate 8. The gripping component position can be adjusted from different directions by coordinating the operation of the first servo motor 6, the lead screw, the connecting block 7 and the first guide rail 4. The position of the gripping plate 8 can be precisely adjusted, forming a three-dimensional adjustment system with the adjusting mechanism 2. This further improves the adaptability of the gripping device to objects of different shapes and sizes. The limiting block 5 ensures the stability of the installation of the first servo motor 6 and ensures that the transmission process is smooth and reliable. The gripping plate 8 and the positioning plate 21 are symmetrically arranged, so that the force on the gripping device is more balanced and the gripping is more stable, which enhances the reliability and safety of the gripping operation.

[0026] The usage and working principle of this device are as follows: First, the device is connected to the robotic arm via the robotic arm joint 3 on one side of the rectangular frame 1. For the adjustment mechanism 2, the second servo motor 26 is installed at the end of the extension plate 25. After starting, the lead screw at its output end rotates, driving the threaded transmission block 28 to move along the lead screw. The transmission block 28 is fixed to the adjustment block 23. The slider 24 on one side of the adjustment block 23 slides on the second guide rail 22, thereby changing the position of the adjustment block 23 to adapt to different gripping needs. At the same time, the limiting block 5 on the lower surface of the center of the rectangular frame 1 fixes the first servo motor 6. When the lead screw of the first servo motor 6 rotates, it drives the threaded connecting block 7 to move. The connecting block 7 is fixed to the clamping plate 8. The clamping plate 8 is slidably connected to the first guide rail 4 on the lower surface of the edge of the rectangular frame 1 through two other sliders 24, thereby realizing the adjustment of the position of the clamping plate 8. The adjustment mechanism 2 and the transmission system of the first servo motor 6 cooperate to adjust the position of the gripping component from different directions, thereby achieving precise gripping of objects of different shapes and sizes.
