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

[0002] In industrial automation, intelligent manufacturing, and logistics sorting, gripping mechanisms, as core actuators, are widely used in material handling, assembly operations, and precision positioning. Traditional gripping technologies mainly include mechanical, hydraulic, and electric drive solutions. While these meet basic requirements to some extent, they still have significant limitations in terms of flexibility, environmental adaptability, and cost control. For example, mechanical gripping mechanisms rely on complex linkage or gear transmission structures, resulting in large size and difficult maintenance; hydraulic drive systems, although providing significant output force, pose risks of oil leakage, have high energy consumption, and struggle to meet clean production requirements; electric gripping mechanisms rely on precision servo control, have poor tolerance to high-temperature, humid, or dusty environments, and are also costly.

[0003] In the existing technology, electric grippers generate impact noise during movement, and the noise also causes the grippers to vibrate, affecting the positioning effect. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a pneumatic gripping mechanism.

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

[0006] A pneumatic gripping mechanism includes a base plate, an mounting plate mounted on the base plate, a first slide rail assembly on one side of the mounting plate, a shaft plate slidably connected to the first slide rail assembly, and a horizontal drive device mounted on the other side of the mounting plate, the drive end of the horizontal drive device being fixedly connected to one side of the shaft plate.

[0007] The mounting plates on both sides of the first slide rail assembly are each equipped with a first mounting base, and the first mounting base is equipped with a first buffer assembly.

A second mounting base is mounted below the second slide rail assembly, and a second buffer assembly is mounted on the second mounting base.

[0009] Preferably, both the first buffer assembly and the second buffer assembly include a hydraulic buffer disposed on the respective first mounting base and the respective second mounting base, and a limiting screw disposed on the respective first mounting base and the respective second mounting base.

[0010] Preferably, the first slide rail assembly includes two first slide rails disposed on one side of the mounting plate and two first sliders slidably disposed on the respective first slide rails.

[0011] Preferably, one side of the shaft plate is fixedly connected to two first sliders.

[0025] 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.

[0026] Reference Figures 1-4 A pneumatic gripping mechanism includes a base plate 1, an mounting plate 2 mounted on the base plate 1, a first slide rail assembly provided on one side of the mounting plate 2, a shaft plate 3 slidably connected to the first slide rail assembly, and a horizontal drive device mounted on the other side of the mounting plate 2, the drive end of the horizontal drive device being fixedly connected to one side of the shaft plate 3.

[0027] The mounting plates 2 on both sides of the first slide rail assembly are each equipped with a first mounting base 4, and a first buffer assembly is installed on each of the first mounting bases 4.

[0028] A second slide rail assembly is provided on the shaft plate 3, and a gripper mounting plate 5 is slidably mounted on the second slide rail assembly. An electric gripper 6 is mounted on one side of the gripper mounting plate 5. A lifting drive assembly is mounted on the top of the shaft plate 3, and the driving end of the lifting drive assembly is connected to the top of the gripper mounting plate 5. A second mounting seat 7 is mounted below the second slide rail assembly, and a second buffer assembly is mounted on the second mounting seat 7.

[0029] The electric gripper 6 is existing technology and will not be described in detail here.

[0030] In use, this device can grip items using an electric gripper 6, and then move the shaft plate 3 and the electric gripper 6 via the first slide rail assembly. When the gripper is in position, the first buffer assembly cushions the shaft plate 3, reducing gripper vibration and increasing gripping effect. The lifting drive assembly can move the gripper mounting plate 5 along the second slide rail assembly, causing the gripper to move downward. When the gripper is in position, the second buffer assembly cushions the gripper mounting plate 5, reducing noise and preventing gripper vibration. This solves the problem in the prior art where noise is generated and gripper vibration affects the positioning effect.

[0031] Furthermore, both the first and second buffer components include hydraulic buffers 8 disposed on the corresponding first mounting base 4 and second mounting base 7, and limiting screws 9 disposed on the corresponding first mounting base 4 and second mounting base 7. The first slide rail assembly includes two first slide rails 10 disposed on one side of the mounting plate 2 and two first sliders 11 slidably disposed on the corresponding first slide rails 10. One side of the shaft plate 3 is fixedly connected to the two first sliders 11. Through the hydraulic buffers 8 and limiting screws 9, the horizontal moving component drives the shaft plate 3 to move on the first slide rails 10 via the first sliders 11. When the shaft plate 3 moves into position, it contacts the hydraulic buffers 8 and limiting screws 9, reducing noise and eliminating positioning rebound.

[0032] The hydraulic damper 8 includes a cylinder and a piston rod movably mounted in the cylinder. The piston rod contacts one end of the piston rod through a shaft plate 3. The piston rod compresses the gas or damping oil in the cylinder to form a buffer against the shaft plate 3. This hydraulic damper 8 is prior art and will not be described in detail here.

[0033] When in use, the position of the limit screw 9 can be adjusted to adjust the buffering effect of the hydraulic damper 8. The shorter the stroke, the greater the damping force.

[0034] Furthermore, the horizontal drive device includes an opening 12 on one side of the mounting plate 2 and a first cylinder 13 disposed on one side of the mounting plate 2. The drive end of the first cylinder 13 is fixedly connected to one side of the shaft plate 3 through a connector 14. The connector 14 is a floating joint. Through the first cylinder 13, the floating joint can be connected to one side of the shaft plate 3. The first cylinder 13 drives the floating joint to move, thereby driving the shaft plate 3 to move along the first slide rail 10.

[0035] Furthermore, the second slide rail assembly includes a second slide rail 15 mounted on one side of the shaft plate 3 and a second slider 16 slidably disposed on the second slide rail 15. The gripper mounting plate 5 is mounted on one side of the second slider 16. Through the second slide rail 15 and the second slider 16, the second cylinder 19 can drive the gripper mounting plate 5 to move along the second slide rail 15 via the second slider 16.

[0036] Furthermore, the two first slide rails 10 are arranged in parallel on one side of the mounting plate 2, and the opening 12 is located between the two first slide rails 10. By arranging the two first slide rails 10 in parallel on one side of the mounting plate 2, the shaft plate 3 can avoid tilting due to torque imbalance during the movement of the first slider 11.

[0037] Furthermore, the lifting drive assembly includes a second cylinder 19 and a locking block 17 disposed at the drive end of the second cylinder 19. The drive end of the second cylinder 19 movably passes through the shaft plate 3. The top of the gripper mounting plate 5 is provided with a locking groove 18. The locking block 17 is adapted to the locking groove. By inserting the locking block 17 into the locking groove 18, the second cylinder 19 can drive the gripper mounting plate 5 to move when it moves.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
