Description

Technical Field

[0001] This utility model relates to the field of isostatic graphite cylinder gripping technology, and in particular to a mechanism for gripping isostatic graphite cylinders. Background Technology

[0002] To reduce the space occupied by isostatic graphite cylinders, they can be placed vertically in the transfer frame, with adjacent cylinders in contact with each other. This not only prevents the isostatic graphite cylinders from tilting during the transfer process but also improves the space utilization rate inside the transfer frame.

[0003] The small gaps between adjacent isostatic graphite cylinders make it difficult for the robotic arm to grasp individual cylinders. Only internal supports can be used for grasping individual cylinders. Because some isostatic graphite cylinders have thin walls, the force applied by the internal supports cannot be too large to avoid breaking the cylinders. This results in instability during the transfer process after grasping, making the isostatic graphite cylinders prone to detachment and damage, affecting subsequent processing. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a mechanism for gripping isostatic graphite cylinders, thereby improving the adaptability to closely arranged adjacent isostatic graphite cylinders and the stability after gripping.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A mechanism for gripping isostatically pressed graphite cylinders includes: a mounting plate, a lifting plate, a first pneumatic finger, a second pneumatic finger, a support block, and a clamping block. The lifting plate is vertically and vertically disposed below the mounting plate. The first pneumatic finger is horizontally disposed at the bottom of the lifting plate, and both ends of the first pneumatic finger are provided with downwardly extending first cantilever arms. The support block is disposed at the bottom outer side of the first cantilever arms. The second pneumatic finger is horizontally disposed at the bottom of the mounting plate and parallel to the first pneumatic finger. Both ends of the second pneumatic finger are provided with second cantilever arms extending downward to the outer side of the first cantilever arms. The clamping block is disposed at the bottom inner side of the second cantilever arms.

[0007] The bottom of the mounting plate is equipped with a telescopic cylinder that is connected to the lifting plate.

[0008] The lifting plate is symmetrically provided with upwardly extending guide posts, and the mounting plate is provided with guide sleeves that correspond one-to-one with the guide posts.

[0009] The mounting plate is provided with a flange on its top.

[0010] The outer side of the support block is provided with an arc-shaped convex surface that corresponds to the inner wall of the isostatic graphite cylinder.

[0011] The inner side of the clamping block is provided with an arc-shaped concave surface corresponding to the outer wall of the isostatic graphite cylinder.

[0012] The beneficial effects of this utility model are as follows: A mechanism for gripping isostatic graphite cylinders first uses a support block to fix the isostatic graphite cylinder internally, then uses a lifting plate to drive the isostatic graphite cylinder to rise, and separates it from other adjacent isostatic graphite cylinders in the height direction, improving the structural adaptability to the close arrangement of adjacent isostatic graphite cylinders. Then, a clamping block is used to clamp the isostatic graphite cylinder, ensuring gripping stability and avoiding the problem of falling off during transportation. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model;

[0014] Figure 2 yes Figure 1 A schematic diagram of the isostatic graphite cylinder being grasped and lifted. Detailed Implementation

[0015] The following is combined Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0016] like Figure 1 The mechanism shown is for gripping isostatic graphite cylinders and includes: mounting plate 1, lifting plate 3, first pneumatic finger 5, second pneumatic finger 4, support block 6 and clamping block 7. The top of the mounting plate 1 is provided with flange 10 to facilitate connection with the robotic arm and realize the movement of the mounting plate 1 to transport the isostatic graphite cylinder to a designated location.

[0017] The lifting plate 3 is vertically and flexibly positioned below the mounting plate 1. In this embodiment, a telescopic cylinder 2 connected to the lifting plate 3 is provided at the bottom of the mounting plate 1. The telescopic cylinder 2 can be controlled by a PLC and a solenoid valve to drive the lifting plate 3 to move up and down. Symmetrically arranged upward-extending guide posts 12 are provided on the lifting plate 3, and guide sleeves 11 corresponding to each guide post 12 are provided on the mounting plate 1. The cooperation between the guide posts 12 and the guide sleeves 11 guides the lifting plate 3 to move up and down, ensuring the smoothness of its movement.

[0018] The first pneumatic finger 5 is horizontally positioned at the bottom of the lifting plate 3 and fixed with screws, allowing the first pneumatic finger 5 to rise and fall with the lifting plate 3. First cantilever arms 9 extending downwards are provided at both ends of the first pneumatic finger 5, and the support block 6 is located at the bottom outer side of the first cantilever arm 9. Figure 1 Therefore, by driving the first cantilever 9 and support block 6 at both ends to move outward through the first pneumatic finger 5, the isostatic graphite cylinder 13 is internally supported, and then the lifting plate 3 rises, as... Figure 2 As shown, the first pneumatic finger 5 and the isostatic graphite cylinder 13 are raised a short distance, causing the top of the corresponding isostatic graphite cylinder 13 to protrude from other adjacent isostatic graphite cylinders, thus achieving a misaligned separation in the height direction.

[0019] In this embodiment, the outer side of the support block 6 is provided with an arc-shaped convex surface corresponding to the inner wall of the isostatic graphite cylinder 13, which improves the fit between the outer side of the support block 6 and the inner wall of the isostatic graphite cylinder 13 and reduces the problem of falling off during the rising process.

[0020] To ensure stability during the gripping and transfer process, the second pneumatic finger 4 is horizontally positioned at the bottom of the mounting plate 1 and parallel to the first pneumatic finger 5. The second pneumatic finger 4 has second cantilever arms 8 extending downwards to the outer side of the first cantilever arm 8 at both ends. The clamping block 7 is located at the bottom inner side of the second cantilever arm 8. Figure 2 As shown, at this time, the second cantilever 8 and clamping block 7 are moved inward by the second pneumatic finger 4 to clamp the top of the outer wall of the isostatic graphite cylinder 13. In conjunction with the support block 6, the isostatic graphite cylinder 13 is prevented from loosening.

[0021] In this embodiment, the inner side of the clamping block 7 is recessed with an arc-shaped concave surface corresponding to the outer wall of the isostatic graphite cylinder 13, ensuring a large contact area between the clamping block 7 and the outer wall of the isostatic graphite cylinder 13, resulting in good anti-slip performance. The clamping block 7 and the support block 6 are both made of rubber blocks to avoid leaving clamping marks on the surface of the isostatic graphite cylinder 13.

[0022] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
