Description

A mechanical gripper flipping mechanism

Technical Field

The utility model relates to the technical field of toy processing, in particular to a mechanical clamping hand turning mechanism.

Background Art

In the production and processing of toys, the toy shell needs to be sprayed with paint or trimmed, and other production processes often require the use of corresponding fixtures to fix it for processing.

After searching, the patent with announcement number CN215788340U discloses a multi-angle positioning fixture for toy production and processing, including a base, two clamping seats are arranged on the top of the base, and connecting disks are arranged on the sides of the two clamping seats close to each other, and fixing mechanisms are arranged inside the connecting disks, one side of one of the clamping seats is movably connected with a movable shaft, one side of the movable shaft passes through the interior of the clamping seat at the corresponding position and is fixedly connected to the surface of the connecting disk, and the surface of the other clamping seat is movably connected with a rotating shaft, and the side of the rotating shaft close to the connecting disk at the corresponding position is fixedly connected to the surface of the connecting disk, and the other side of the movable shaft is fixedly connected to a turning handle, and the surface of one of the clamping seats close to the movable shaft position is fixedly connected to a fixed block, and a second spring is fixedly connected to the interior of the fixed block.

Although the multi-angle positioning fixture for toy production and processing mentioned above can adjust the placement state of the toy shell after fixing the toy shell so that it can be fixed at multiple angles, the threaded rod used therein will cause the two threaded sleeves to move in the same direction when rotating, resulting in the inability to clamp the toy shell, and the handle and the turning handle need to be frequently twisted for adjustment, which is inconvenient to use and is not conducive to improving processing efficiency.

In view of the above problems, the utility model document proposes a mechanical gripping hand flipping mechanism.

Please refer to Figures 1-4, a mechanical gripper flipping mechanism, which is used in the field of toy processing, includes:

A base 1 is provided with a fixing groove 2 at the top of the top of the base 1, and two ends of the inner wall of the fixing groove 2 are rotatably installed with a bidirectional threaded screw 3, and a first driving motor 4 for driving the bidirectional threaded screw 3 to rotate is fixedly installed on the outer wall of the base 1, and a support column 7 is fixedly provided on the top of the two screw seats on the bidirectional threaded screw 3, and a mounting block 8 is fixedly provided on the top of the support column 7, and a rotating rod 9 is rotatably installed on the inner side of the two mounting blocks 8, and a second driving motor 10 for driving the corresponding rotating rod 9 to rotate is fixedly installed on one of the mounting blocks 8, and a main splint 11 is fixedly provided on the other end of the rotating rod 9, and the bidirectional threaded screw 3 is fixedly provided with a first driving motor 4 for driving the bidirectional threaded screw 3 to rotate. Slide blocks 5 are fixedly provided on both sides of the screw seat on the rod 3, and a slide groove 6 for slidingly installing the slide block 5 is provided on the inner wall of the fixed groove 2. The slide block 5 slides in the slide groove 6 to prevent the screw seat on the bidirectional threaded screw 3 from rotating and improve its sliding stability. The bidirectional threaded screw 3 is driven to rotate by the first drive motor 4. Under the limiting action of the slide groove 6, the two screw seats are urged to approach each other until the two main splints 11 clamp the toy shell. After that, the corresponding rotating rod 9 can be driven to rotate by the second drive motor 10, thereby driving the two main splints 11 to rotate to adjust the flipping angle of the toy shell for processing operations.

An extension component is arranged on the main plate 11 and is used to expand the clamping surface of the main plate 11. The extension component includes two rectangular long holes 12 symmetrically arranged on the main plate 11. The same extension clamp 13 is slidably connected in the two rectangular long holes 12. The main plate 11 and the extension clamp 13 are fixed by a fixing bolt 14. A flat pad 15 that is flush with the extension clamp 13 is fixed on the clamping surface of the main plate 11 to prevent the clamping surface of the main plate 11 from being unable to contact the toy shell. The flat pad 15 is preferably made of rubber material to increase the friction with the toy shell. If the toy shell is large, the fixing bolt 14 can be unscrewed to move the extension clamp 13 downward, thereby expanding the clamping surface of the main plate 11 and improving the clamping and fixing effect on the toy shell.

Embodiment 2

Improvements based on Example 1:

Please refer to Figure 1. A mounting seat 16 is fixedly provided in the center of the top of the base 1. A placement plate 18 is provided on the top of the mounting seat 16. An electric push rod 17 is fixedly installed between the placement plate 18 and the mounting seat 16. The toy shell can be placed on the placement plate 18, and then the placement plate 18 is lifted by the electric push rod 17 to raise the toy shell to a suitable clamping height so that the two main clamping plates 11 can clamp and fix it. Then, the electric push rod 17 is lowered to prevent the toy shell from hitting the placement plate 18 and causing damage during the subsequent flipping process.

However, as is well known to those skilled in the art, the working principles and wiring methods of the first drive motor 4, the second drive motor 10 and the electric push rod 17 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model; in the absence of conflicts, the embodiments of the utility model and the features in the embodiments can be combined with each other. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
