Description

Technical Field

[0001] This utility model relates to the field of gripping mechanism technology, and in particular to a novel gripping mechanism. Background Technology

[0002] In fields such as automated production and logistics handling, the gripping mechanism is the core component for grasping and transferring materials, and its performance directly affects production efficiency and operational safety.

[0003] Traditional gripping mechanisms are prone to power loss when gripping heavy objects or operating for extended periods, resulting in insufficient gripping force and a risk of material falling. Furthermore, existing gripping mechanisms have deficiencies in limiting the position after gripping, relying heavily on continuous holding force from the drive components to maintain the clamping state. If the external power supply is interrupted or the drive components malfunction, the grippers lose their clamping force, failing to guarantee stable material holding and severely limiting the application of gripping mechanisms in complex working conditions. To address these issues, this application proposes a novel gripping mechanism. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel gripping mechanism. Through the design of a rotating pneumatic rod driving the gripper limiting plate to rotate and limit the gripper, the gripper forms a mechanical limit after gripping, eliminating the need for continuous holding force from the drive component. Even if the external power supply is interrupted or the drive component fails, stable clamping can still be achieved, significantly enhancing the adaptability of the mechanism under complex working conditions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel gripping mechanism includes a connecting plate. Two linear guide rails are fixedly connected to the bottom of the connecting plate. Two sliders are slidably connected to the outer wall of each linear guide rail. A movable plate is fixedly connected to each pair of sliders. Two drive cylinders are fixedly connected to the bottom of the connecting plate. The output ends of the two drive cylinders are fixedly connected to their corresponding movable plates. A vertical plate is fixedly connected to the bottom of each movable plate. A clamping plate is fixedly connected to the bottom of each vertical plate. A rotating pneumatic rod is fixedly connected to the bottom of the connecting plate. A gripper limiting plate is fixedly connected to the bottom of the rotating pneumatic rod. A gripping component is located below the connecting plate.

[0007] Preferably, the linear guide rail has two limiting grooves, and the slider has a C-shaped groove, with the inner wall of the C-shaped groove fitted onto the outer wall of the limiting groove and slidably connected thereto.

[0008] Preferably, an L-shaped mounting block is fixedly connected to the bottom of the connecting plate, the driving cylinder passes through the L-shaped mounting block and is fixedly connected to it, a moving plate is fixedly connected to the output end of the driving cylinder, and the bottom of the fixed block is fixedly connected to the top of the moving plate.

[0009] Preferably, the connecting plate has four mounting holes that extend through it, and the four mounting holes are arranged in a rectangular pattern.

[0010] Preferably, the bottom of the gripper limiting plate is on the same horizontal plane as the bottom of the two grippers.

[0011] Preferably, the opposite sides of both vertical plates and clamps are provided with a protective layer, the protective layer being made of rubber.

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

[0013] 1. Through the cooperation of linear guide rails and sliders, as well as the guiding and limiting structure of limit grooves and C-shaped grooves, the moving path of the moving plate is precisely constrained, ensuring stable movement and accurate positioning of the gripper, and greatly improving the success rate of gripping and the accuracy of material placement.

[0014] 2. The design of rotating the gripper limit plate by using a rotating pneumatic rod to achieve mechanical limitation after gripping, eliminates the need for continuous holding force from the drive components. Even if the external power supply is interrupted or the drive components fail, stable clamping can still be achieved, significantly enhancing the adaptability of the mechanism under complex working conditions.

[0015] 3. In this application, the travel of the gripper is equal to the travel of the drive cylinder, which occupies less space, reduces space and energy consumption, and is safer.

[0016] In summary, the design of using a rotating pneumatic rod to drive the gripper limit plate to rotate and limit the gripper creates a mechanical limit after gripping, eliminating the need for continuous holding force from the drive components. Even if the external power supply is interrupted or the drive components fail, stable clamping can still be achieved, significantly enhancing the adaptability of the mechanism under complex working conditions.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A novel gripping mechanism includes a connecting plate 1 with four mounting holes arranged in a rectangular pattern. The connecting plate 1 can be connected to an external robotic arm via bolts to grip objects. Two linear guide rails 2 are fixedly connected to the bottom of the connecting plate 1. These linear guide rails 2 provide a guiding path for the sliding of sliders 3, ensuring stable movement. Two sliders 3 are slidably connected to the outer wall of each linear guide rail 2. Two limiting grooves 10 are provided on the linear guide rails 2, and C-shaped grooves 11 are provided on the sliders 3. The inner wall of the C-shaped groove 11 is fitted onto the outer wall of the limiting groove 10 and slidably connected to it. The cooperation of the limiting groove 10 and the C-shaped groove 11 further restricts the direction and range of movement of the sliders 3.

[0024] Each pair of sliders 3 is fixedly connected to a movable plate 4. The sliding of the sliders 3 drives the movable plate 4 to move synchronously to achieve position adjustment. Two drive cylinders 5 are fixedly connected to the bottom of the connecting plate 1. The drive cylinders 5 provide power for the movement of the movable plate 4 as drive components. An L-shaped mounting block 13 is fixedly connected to the bottom of the connecting plate 1. The drive cylinders 5 pass through the L-shaped mounting block 13 and are fixedly connected to it. The output ends of the two drive cylinders 5 are fixedly connected to their corresponding movable plates 4. The output ends of the drive cylinders 5 are fixedly connected to the movable plates 4. The bottom of the fixed block 14 is fixedly connected to the top of the movable plate 4. A vertical plate 6 is fixedly connected to the bottom of each movable plate 4. The movable plate 4 drives the vertical plate 6 to move, thereby achieving the position adjustment of the vertical plate 6. A clamping plate 7 is fixedly connected to the bottom of each vertical plate 6. The opposite sides of the two vertical plates 6 and the clamping plate 7 are provided with a protective layer. The protective layer is made of rubber and serves a protective function.

[0025] A rotating pneumatic rod 8 is fixedly connected to the bottom of the connecting plate 1. The rotating pneumatic rod 8 can drive the gripper limiting plate 9 to rotate 90 degrees. The gripper limiting plate 9 is fixedly connected to the bottom of the rotating pneumatic rod 8. The bottom of the gripper limiting plate 9 is on the same horizontal plane as the bottom of the two clamping plates 7, which is used to limit the vertical plates 6 and clamping plates 7 on both sides. A gripping component 12 is provided below the connecting plate 1.

[0026] In this invention, the gripping mechanism is moved above the gripper 12 by a robotic arm connected to the top of the connecting plate 1. Two vertical plates 6 and a clamping plate 7 are then inserted into the gripper 12. At this time, two drive cylinders 5 are activated. The contraction of the two drive cylinders 5 drives the moving plates 4, vertical plates 6, and clamping plates 7 on both sides to move in opposite directions. During this process, the slider 3 slides on the linear guide rail 2 to ensure the stability of the moving plates 4 until the vertical plates 6 and clamping plates 7 cooperate to grip the gripper 12. During the gripping process, the mechanism is activated at this time. The rotating air rod 8 drives the gripper limiting plate 9 to rotate 90 degrees, changing the gripper limiting plate 9 from the original Y-axis direction to the X-axis direction. This causes the two ends of the gripper limiting plate 9 to abut against the inner wall of the clamping plate 7, thereby limiting the vertical plates 6 and clamping plate 7 on both sides to prevent relative movement of the vertical plates 6 and clamping plate 7 during the gripping and lifting movement. Preventing the vertical plates 6 and clamping plate 7 from moving inward can eliminate the requirement for holding force at the output end of the drive cylinder 5, and clamping can still be achieved even under extreme conditions of external power interruption.
