Description

Technical Field

[0001] This utility model belongs to the field of material handling equipment technology, and specifically relates to a material handling clamping mechanism. Background Technology

[0002] Material handling is crucial for improving warehouse operational efficiency and directly impacts production efficiency. In manufacturing companies, logistics managers are typically responsible for all aspects of material handling, including receiving goods into the warehouse, storing goods within the warehouse, moving goods from storage locations to order sorting areas, and finally arriving at the shipping area for shipment. Specific material handling operations include: horizontal or inclined movement; vertical loading and unloading; lifting or lowering for palletizing or picking; turning around a vertical line; and turning around a horizontal axis. Due to increased automation and expanded production scale in industrial production, and the significant impact of material handling costs on profitability, companies are increasingly adopting large-scale, efficient, and automated material handling machinery. For this machinery, rapid clamping and releasing of materials is a key means of improving handling efficiency. Current clamping mechanisms mostly use robotic arms or pneumatic grippers to hold materials. Due to the influence of the drive source and movement accuracy, it is difficult to ensure that the material will not deviate when clamping. When releasing the material, the clamping mechanism remains fixed, but the position of the clamped material may deviate slightly. This results in inconsistent landing points of the released material, requiring additional correction mechanisms to assist in handling the material, which increases handling costs. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the background art and provide a material handling clamping mechanism that can ensure that the position of the material remains unchanged before and after clamping, and facilitate the transfer of materials during handling so that they are stacked neatly.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a material handling clamping mechanism, comprising a first moving mechanism, a second moving mechanism, a moving frame for mounting both, and a rotating assembly. The lower end of the first moving mechanism is further provided with a first clamping arm, and the lower end of the second moving mechanism is further provided with a second clamping arm. The rotating assembly includes a mounting plate, a bearing seat, a large gear disc, a rack, and a rack fixing plate. The mounting plate is located at the bottom center of the moving frame. The large gear disc is connected to the bottom surface of the mounting plate via a rotating shaft. The rotating shaft and the large gear disc are rotatably connected via the mounted bearing seat. There are two racks that are rotationally symmetrical and mesh with the large gear disc, and the two racks are respectively connected to the first moving mechanism and the second moving mechanism. The moving frame is further provided with a driving assembly for driving the first moving mechanism / second moving mechanism, and the mounting plate is further provided with a guide mechanism that is tactilely connected to the racks.

[0005] Furthermore, the guiding mechanism includes an I-beam frame and a guide wheel, with the guide wheel connected to the I-beam frame, so that the guide wheel supports the rack while rolling with the rack.

[0006] Furthermore, the first moving mechanism / second moving mechanism consists of a front slide, a rear slide, a slide rod, a sliding frame, and a sliding plate. The front slide is located at the edge of the mounting plate, the rear slide is connected to the moving frame, the slide rod is fastened between the front slide and the rear slide, the sliding frame is connected to the slide rod, the lower end of the sliding frame is connected to the sliding plate, and the lower end of the sliding plate is connected to the first clamping arm.

[0007] Furthermore, the first clamping arm / second clamping arm includes a clamping arm and a clamping plate connected to the lower end of the sliding plate. The clamping plate is vertically fixed on the clamping arm, and a set of connecting holes is also provided on the clamping plate.

[0008] Furthermore, the drive assembly includes a linear drive component, a fixed frame, a pusher, and a push plate. The linear drive component is mounted on the fixed frame, and its telescopic end is provided with a pusher. The lower end of the pusher is bolted to the push plate connected to the first moving mechanism / second moving mechanism.

[0009] Furthermore, the connecting holes are located at both ends of the clamping plate.

[0010] Furthermore, the linear drive component is a linear telescopic cylinder, which is connected to an external pneumatic source to provide driving force.

[0011] The beneficial effects of this utility model are: 1) This utility model is equipped with a rotating component, which drives the moving mechanism on both sides to move synchronously through the meshing of a toothed disc and two straight racks. The clamping arm below the moving mechanism can be bolted to the contoured jaw shell, which fits the outer contour of the material and clamps it tightly and firmly, and ensures that the position of the material after clamping remains consistent. It is suitable for large-scale handling and clamping, and the structure is simple and easy to use. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0020] Example: Figure 1-6 As shown, the material handling clamping mechanism of this utility model includes a first moving mechanism 1, a second moving mechanism 2, a moving frame 3 for mounting both, and a rotating assembly 4. The lower end of the first moving mechanism 1 is also provided with a first clamping arm 5, and the lower end of the second moving mechanism 2 is also provided with a second clamping arm 6. The rotating assembly 4 includes a mounting plate 7, a bearing seat 8, a large gear 9, a rack 10, and a rack fixing plate 11. The mounting plate 7 is located at the bottom center of the moving frame 3. The large gear 9 is connected to the bottom surface of the mounting plate 7 through a rotating shaft. The rotating shaft and the large gear 9 are rotatably connected through the mounted bearing seat 8. There are two racks 10, which are rotationally symmetrical and mesh with the large gear 9. The two racks 10 are respectively connected to the first moving mechanism 1 and the second moving mechanism 2. The moving frame 3 is also provided with a driving assembly 12 for driving the first moving mechanism 1 / the second moving mechanism 2. The mounting plate 7 is also provided with a guide mechanism 13 that is tactilely connected to the racks 10.

[0021] In this embodiment, a drive assembly 12 is installed on the top surface of the mobile frame 3, and a rotating assembly 4 is installed at the center of the bottom surface. A first moving mechanism 1 and a second moving mechanism 2 are respectively installed on both sides of the mobile frame 3. A first clamping arm 5 is installed at the lower end of the first moving mechanism 1, and a second clamping arm 6 is installed at the lower end of the second moving mechanism 2. The rotating assembly 4 meshes with the first moving mechanism 1 and the second moving mechanism 2 to drive the first clamping arm 5 and the second clamping arm 6 to move closer to or away from the center of the rotating assembly 4 synchronously. When the material is being transported, the material conveying point is set directly below the center of the rotating assembly 4. When the clamping arm clamps the material, it can ensure that the stepping distance on the left and right sides is the same, so that the material always remains in a fixed position when clamped, avoiding displacement and increasing the subsequent palletizing or transfer process.

[0022] The first moving mechanism 1 / second moving mechanism 2 consists of a front slide 16, a rear slide 17, a slide rod 18, a sliding frame 19, and a sliding plate 20. The front slide 16 is located on the edge of the mounting plate 7, the rear slide 17 is connected to the moving frame 3, the slide rod 18 is fastened between the front slide 16 and the rear slide 17, the slide frame 19 is connected to the slide rod 18, the lower end of the slide frame 19 is connected to the sliding plate 20, and the lower end of the sliding plate 20 is connected to the first clamping arm 5.

[0023] The first clamping arm 5 / second clamping arm 6 includes a clamping arm 21 and a clamping plate 22 connected to the lower end of the sliding plate 20. The clamping plate 22 is vertically fixed on the clamping arm 21, and a set of clamping plates 23 is also provided on the clamping plate 22.

[0024] The drive assembly 12 includes a linear drive 24, a fixed frame 25, a pusher 26, and a pusher plate 27. The linear drive 24 is mounted on the fixed frame 25, and its telescopic end is provided with the pusher 26. The lower end of the pusher 26 is bolted to the pusher plate 27 connected to the first moving mechanism 1 / second moving mechanism 2.

[0025] In this embodiment, the mounting plate 7 is located at the bottom center of the movable frame 3. The large gear disk 9 is connected to the bottom surface of the mounting plate 7 via a rotating shaft. The rotating shaft and the large gear disk 9 are rotatably connected by the mounted bearing seat 8. There are two straight racks 10 that are rotationally symmetrical and mesh with the large gear disk 9. The other ends of the two straight racks 10 are respectively bolted to the straight rack fixing plate 11. The sliding plate 20 is connected to the push plate 27 above and the straight rack fixing plate 11 below. When the linear drive component 24 extends, it will drive the push frame 26 to move to both sides, causing the sliding plate 20 to move to the left away from the rotating component 4. When the sliding plate 20 moves, it drives the straight rack fixing plate 11 to move synchronously, causing the straight racks 10 meshing with the large gear disk 9 to move to the left, thereby driving the large gear disk 9 to rotate counterclockwise. The other gear rack 10 is driven to move to the right, simultaneously moving the second moving mechanism 2 to the right and the second clamping arm 6 to the right, causing the first clamping arm 5 and the second clamping arm 6 to extend to both sides synchronously. During this process, the two gear racks 10 are of the same size and mesh on both sides of the large gear disk 9, and are rotationally symmetrical. The drive assembly 12 drives the first moving mechanism 1 and the left gear rack 10 to move, making the left gear rack 10 the power transmission end, while the large gear disk 9 and the right gear rack 10 are the driven ends. When the linear drive component 24 extends, it drives the first clamping arm 5 and the second clamping arm 6 to extend outward, facilitating the release of materials. Conversely, when the linear drive component 24 retracts, it drives the two to move inward, facilitating the clamping of materials for transport and movement. The linear drive component 24 uses a linear telescopic cylinder, which is connected to an external pneumatic source to provide driving force, making the control more precise and faster, enabling rapid clamping and release of materials, and improving transport efficiency.

[0026] The guiding mechanism 13 includes an I-beam frame 14 and a guide wheel 15. The guide wheel 15 is connected to the I-beam frame 14, so that the guide wheel 15 supports the rack 10 while rolling with the rack 10.

[0027] In this embodiment, the I-beam frame 14 is installed on the front and rear sides of the mounting plate 7, and the lower part is rotatably connected to the guide wheel 15. When the two straight racks 10 mesh with the large gear disk 9, they are also limited by the guide wheel 15 to ensure that the connection between the straight racks 10 and the large gear disk 9 is firm and stable and will not be dislodged under force. At the same time, in order to facilitate the clamping of materials with different shapes and contours, a set of clamping plates 23 is provided at both the front and rear ends of the clamping plate 22. This facilitates the installation of grippers that are adapted to the material contours, improves the application range of the clamping mechanism, and enables it to be used in various material handling environments, making it highly practical.

[0028] This utility model is equipped with a rotating component. Through the meshing of a toothed disc and two straight racks, the moving mechanisms on both sides move synchronously. The clamping arm below the moving mechanism can be bolted to the contoured jaw shell, which fits the outer contour of the material and clamps it tightly and firmly, ensuring that the position of the material remains consistent after clamping. It is suitable for large-volume handling and clamping, and has a simple structure and is easy to use.

[0029] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
