Description

Technical Field

[0001] This utility model relates to the field of mechanical automation technology, and in particular to a mechanical gripper. Background Technology

[0002] A mechanical gripper is an automated device that mimics certain human hand movements to grasp, move, or manipulate objects or tools according to a fixed program. Mechanical grippers can complete various pre-programmed tasks, combining the advantages of both human and mechanical grippers in their design and performance. They can replace heavy manual labor to achieve mechanization and automation of production and can operate in hazardous environments to protect personal safety. Mechanical grippers are widely used in the automated machining of many products. Their main functions include clamping workpieces, placing them in the machining position, and removing them after machining. They can replace manual operation, significantly improving production efficiency and ensuring a high level of production safety.

[0003] However, in the existing technology, mechanical grippers usually use direct centering gripping when picking up materials. In the production environment, the mechanical grippers are unstable in grasping materials, and some mechanical grippers cannot adapt to workpieces of different diameters. They are prone to falling off, which poses a significant safety hazard and affects the service life of the workpieces. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a mechanical gripper to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A mechanical gripper includes a base plate, a solenoid valve connected above the base plate, and a gripping mechanism connected below the base plate. The gripping mechanism includes a mounting frame, which comprises a top plate and left and right side plates. The inner wall of the top plate is fixedly connected to the pneumatic gripper. A hanging claw is located below the pneumatic gripper and connected to it via a connecting piece. A sliding rod is provided between the left and right side plates, and a sliding bearing is slidably mounted on the sliding rod. The hanging claw is fixedly connected to the sliding bearing. The solenoid valve controls the opening and closing of the pneumatic gripper, and the pneumatic gripper drives the hanging claw to move closer or further apart. Through the linkage control of the solenoid valve and the pneumatic gripper, precise start and stop of the gripping action is achieved. The hanging claw slides freely along the sliding rod via the sliding bearing, automatically adjusting the gripping position according to the shape and size of the object being gripped, effectively adapting to irregular or irregularly shaped workpieces and reducing the risk of deformation during gripping.

[0007] Furthermore, a limiting component is provided at the top of the mounting bracket to control the opening and closing limits of the claw.

[0008] Furthermore, the grippers are mirror-symmetrically distributed, openable and closable L-shaped structures. The L-shaped structure, through its right-angle extension design, enables the grippers to open and close within a limited space, ensuring stable workpiece transport.

[0009] Furthermore, the limiting assembly is equipped with a limiting rod, the free end of which is equipped with a limiting cap. The limiting rod passes through a through hole in the side plate and extends along the Y-axis. The limiting rod controls the opening and closing limits of the claw.

[0010] Furthermore, the pneumatic gripper adopts a dual-piston cylinder structure, achieving the clamping action through piston rod linkage. The symmetrical layout of the dual-piston cylinders ensures that the clamping force is evenly distributed on both sides, avoiding workpiece displacement or gripper deformation caused by uneven force on one side, thus improving clamping stability.

[0011] Furthermore, the gripper is fixedly connected directly below the pneumatic gripper.

[0012] Furthermore, the mounting bracket uses a combination of double sliding rods and claws to grip materials, with the double sliding rods increasing the flexibility and stability of the claw movement.

[0013] Furthermore, the device controls the tightness of the gripper by allowing gas to enter and exit the gripper cylinder.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In practical use, this utility model achieves significant optimization in terms of clamping accuracy, structural stability, safety, and efficient operation through the synergistic effect of the solenoid valve and the clamping mechanism. The clamping mechanism forms a stable support system through the frame structure of the top plate and the left and right side plates. With the guiding effect of the double sliding rods and sliding bearings, it ensures the movement trajectory of the claws during the clamping process and avoids clamping failure caused by trajectory deviation.

[0016] 2. In practical use, the claw of this utility model has an openable L-shaped structure and a mirror symmetrical layout, which allows it to adapt to workpieces of different sizes or shapes. The clamping position can be automatically adjusted by the free sliding of the sliding rod through the sliding bearing. The double sliding rod enhances the flexibility and stability of the claw movement and further expands the clamping range.

[0017] 3. In practical use, the solenoid valve directly controls the air intake or exhaust of the air gripper cylinder, achieving millisecond-level response for the opening and closing of the gripper. Combined with the high-speed driving capability of the dual piston cylinder, it significantly improves the operating efficiency of the automated production line. In addition, the limit rod in the limit component passes through the through hole in the side plate and extends along the Y-axis direction, precisely controlling the opening and closing limit of the gripper, preventing over-gripping or loosening, and avoiding damage to the workpiece or jamming of the gripper.

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.

[0025] like Figure 1-3 As shown, according to an embodiment of the present invention, a mechanical gripper is provided, including a base plate 1, a solenoid valve 2 connected above the base plate 1, and a gripping mechanism 3 connected below the base plate 1. The gripping mechanism 3 includes a mounting frame 31, which includes a top plate 311 and left and right side plates 312. The inner wall of the top plate 311 is fixedly connected to a pneumatic gripper 32. A hanging claw 33 is disposed below the pneumatic gripper 32 and connected to the pneumatic gripper 32 through a connecting piece 34. A sliding rod 313 is provided between the left and right side plates 312, and a sliding bearing 314 is slidably disposed on the sliding rod 313. The hanging claw 33 is fixedly connected to the sliding bearing 314. The solenoid valve 2 controls the opening and closing of the pneumatic gripper 32, and the pneumatic gripper 32 drives the hanging claw 33 to move closer to or away from each other.

[0026] The top of the mounting bracket 31 is provided with a limiting component 35, which controls the opening and closing limit of the claw 33. The mounting bracket 31 uses a double sliding rod 313 to cooperate with the claw 33 to clamp the material. The double sliding rod 313 increases the flexibility and stability of the claw 33's movement.

[0027] The limiting assembly 35 is provided with a limiting rod 351, and a limiting cap 352 is provided at the free end of the limiting rod 351. The limiting rod 351 passes through the through hole provided in the side plate and extends along the Y-axis direction.

[0028] The pneumatic gripper 32 adopts a double piston cylinder structure, and the clamping action is achieved through the linkage of the piston rod. The device controls the tightness of the hanging claw 33 by the air entering and exiting the pneumatic gripper 32 cylinder. The hanging claw 33 is fixedly connected to the bottom of the pneumatic gripper 32 and has a mirror-symmetrically distributed openable L-shaped structure.

[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, in actual use, this utility model achieves rapid response and efficient operation through the linkage control of the solenoid valve 2 and the gripping mechanism 3. The solenoid valve 2 directly controls the opening and closing action of the pneumatic gripper 32, and in conjunction with the transmission structure of the connecting piece 34, it realizes the rapid closing and opening of the gripper 33, and achieves precise start and stop of the gripping action. This solves the problem in the prior art where the mechanical gripper is unstable in grasping materials in the production environment, and there is a risk of easy detachment, which poses a significant safety hazard and affects the accuracy and effectiveness of transportation work.
