Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, specifically to a material clamping device for a spinning machine. Background Technology

[0002] A spinning machine is a mechanical device used for the plastic forming of metals. It mainly uses rotation and the application of pressure to deform and flow metal materials, thereby forming them into specific shapes. A spinning machine is usually composed of a bed, servo system, carriage, spinning wheel frame, etc. It can realize automatic processing and control, and has high precision and reliability. The technical principle of a spinning machine is to rotate the metal material so that the stress point moves from a point to a line, and then from a line to a surface, while applying pressure in a certain direction, causing the material to deform and flow along that direction. This technology can be used to manufacture rotating bodies of various shapes, such as deep drawing, flanging, necking, bulging, and hemming.

[0003] When feeding materials into a spinning machine, a robotic arm is usually used. However, due to long-term operation or other reasons, the center of the circular material plate may not coincide with the center of the spinning machine. This results in the product's size and shape not meeting the requirements after spinning, thus reducing the product's quality. Utility Model Content

[0004] To achieve the above objectives, this utility model proposes a clamping device for a spinning machine.

[0005] The technical solution of this utility model is implemented as follows: A clamping device for a spinning machine includes a base, a first fixed frame and a second fixed frame fixedly connected to the top of the base, a clamping mechanism for positioning provided on the second fixed frame, a first cylinder fixedly connected inside the second fixed frame, a rotating block rotatably connected to one side of the first cylinder, a first fixed seat fixedly connected outside the first cylinder, the first fixed seat hinged to the second cylinder, a connecting seat fixedly connected to one side of the second cylinder, a second fixed seat fixedly connected to the outside of the first cylinder, the second fixed seat hinged to a clamping rod, a first support arm rotatably connected inside the second fixed seat, a connecting rod fixedly connected to one end of the first support arm, a second support arm rotatably connected inside the clamping rod, a motor fixedly connected inside the first fixed frame, a rotating shaft fixedly connected to one side of the motor, a fixed block fixedly connected to one side of the rotating shaft, a mold fixedly connected to the outside of the fixed block, and a material plate provided between the rotating block and the fixed block.

[0006] Preferably, the connecting rod is rotatably connected to the connecting seat and the second support arm.

[0007] Preferably, the end of the clamping rod is arc-shaped.

[0008] Preferably, a support frame is fixedly connected to the top of the base, and the support frame is rotatably connected to the rotating shaft.

[0009] Preferably, a first telescopic block is slidably connected inside the rotating block, a first ball is rotatably connected inside the first telescopic block, and a first spring is fixedly connected inside the rotating block.

[0010] Preferably, a second telescopic block is slidably connected inside the fixed block, a second ball bearing is rotatably connected inside the second telescopic block, and a second spring is fixedly connected inside the fixed block.

[0011] Preferably, the first telescopic block is fixedly connected to the first spring, and the second telescopic block is fixedly connected to the second spring.

[0012] This utility model has the following beneficial effects:

[0013] The clamping device of this spinning machine extends the connecting seat via a second cylinder. The connecting seat then pushes the connecting rod to move, which in turn pushes the first support arm to rotate on the second fixed seat. Simultaneously, it also pushes the second support arm to move, causing the second support arm to push the clamping rod to rotate on the second fixed seat. The clamping rod, through rotation, touches the edge of the material plate, while the other clamping rods do not touch the edge of the material plate. The clamping rod then pushes the material plate. The first and second ball bearings reduce the friction between the material plate and the first and second telescopic blocks, making it easier for the clamping rod to push the material plate. When the second cylinder stops extending, the clamping rod and the other clamping rods all touch the edge of the material plate, causing the center of the material plate to coincide with the center of the rotating block and the fixed block. This ensures that the center of the circular material plate coincides with the center of the spinning machine, preventing the product size and shape from not meeting requirements after spinning, thereby ensuring product quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] like Figure 1-6 As shown, the clamping device of the spinning machine provided in this embodiment includes a base 1. A first fixed frame 2 and a second fixed frame 3 are fixedly connected to the top of the base 1. A clamping mechanism 4 for positioning is provided on the second fixed frame 3. A first cylinder 401 is fixedly connected inside the second fixed frame 3. A rotating block 402 is rotatably connected to one side of the first cylinder 401. A first fixed seat 403 is fixedly connected to the outside of the first cylinder 401. The first fixed seat 403 is hinged to the second cylinder 404. A connecting seat 405 is fixedly connected to one side of the second cylinder 404. A second fixed base 409 is externally fixedly connected, and the second fixed base 409 is hinged to the clamping rod 410. A first support arm 407 is rotatably connected inside the second fixed base 409. A connecting rod 406 is fixedly connected to one end of the first support arm 407. A second support arm 408 is rotatably connected inside the clamping rod 410. A motor 5 is fixedly connected inside the first fixed frame 2. A rotating shaft 6 is fixedly connected to one side of the motor 5. A fixed block 8 is fixedly connected to one side of the rotating shaft 6. A mold 9 is fixedly connected to the outside of the fixed block 8. A material plate 10 is set between the rotating block 402 and the fixed block 8.

[0024] Furthermore, the connecting rod 406 is rotatably connected to the connecting seat 405 and the second support arm 408.

[0025] By adopting the above technical solution, by pulling the connecting seat 405, the connecting seat 405 drives the first support arm 407 and the second support arm 408 to rotate together through the connecting rod 406.

[0026] Furthermore, the end of the clamp 410 is arc-shaped.

[0027] By adopting the above technical solution, the end of the clamping rod 410 is arc-shaped, which increases the number of contact points between the clamping rod 410 and the material plate 10, making it easier for the clamping rod 410 to push the material plate 10 to move.

[0028] Furthermore, a support frame 7 is fixedly connected to the top of the base 1, and the support frame 7 is rotatably connected to the rotating shaft 6.

[0029] By adopting the above technical solution, the rotating shaft 6 is supported by the support frame 7, so that the rotating shaft 6 can remain stable when rotating.

[0030] Furthermore, a first telescopic block 11 is slidably connected inside the rotating block 402, a first ball bearing 12 is rotatably connected inside the first telescopic block 11, and a first spring 13 is fixedly connected inside the rotating block 402.

[0031] Furthermore, a second telescopic block 14 is slidably connected inside the fixed block 8, a second ball bearing 15 is rotatably connected inside the second telescopic block 14, and a second spring 16 is fixedly connected inside the fixed block 8.

[0032] By adopting the above technical solution, the material plate 10 is clamped in the middle by the first ball 12 on the first telescopic block 11 and the second ball 15 on the second telescopic block 14, while the first spring 13 and the second spring 16 prevent the first telescopic block 11 and the second telescopic block 14 from clamping the material plate 10 tightly, and the first ball 12 and the second ball 15 allow the material plate 10 to move when it is pushed.

[0033] Furthermore, the first telescopic block 11 is fixedly connected to the first spring 13, and the second telescopic block 14 is fixedly connected to the second spring 16.

[0034] By adopting the above technical solution, the first telescopic block 11 and the second telescopic block 14 respectively squeeze the first spring 13 and the second spring 16. The elastic force of the first spring 13 and the second spring 16 enables the first telescopic block 11 and the second telescopic block 14 to clamp the material plate 10 and prevent it from falling.

[0035] Working principle: The robotic arm moves the material plate 10 between the rotating block 402 and the fixed block 8, then activates the first cylinder 401. The first cylinder 401 extends the rotating block 402 towards the material plate 10. The first telescopic block 11 on the rotating block 402 and the second telescopic block 14 on the fixed block 8 clamp the material plate 10 in the middle. As the rotating block 402 continues to extend, the first telescopic block 11 compresses the first spring 13 inside the fixed block 8, and the second telescopic block 14 compresses the second spring 16 inside the fixed block 8. The first spring 13 and the second spring 16... The elastic force of spring 16 causes the first telescopic block 11 and the second telescopic block 14 to clamp the material plate 10 and prevent it from falling. At this time, the first cylinder 401 stops extending the rotating block 402, so that the rotating block 402 and the fixed block 8 do not clamp the material plate 10. Then, the second cylinder 404 is activated, which extends the connecting seat 405. The connecting seat 405 then pushes the connecting rod 406 to move. The connecting rod 406 then pushes the first support arm 407 to rotate on the second fixed seat 409. At the same time, it also pushes the second support arm 408 to move, so that the second support arm 407 rotates on the second fixed seat 409. Arm 408 pushes clamping rod 410 to rotate on the second fixed seat 409. Through rotation, clamping rod 410 touches the edge of material plate 10, while other clamping rods 410 do not. Clamping rod 410 then pushes material plate 10. The first ball bearing 12 and the second ball bearing 15 reduce friction between material plate 10 and the first telescopic block 11 and the second telescopic block 14, making it easier for clamping rod 410 to push material plate 10. When the second cylinder 404 stops extending, clamping rod 410 and the other clamping rods 410 all touch the edge of material plate 10, thus... The center of the material plate 10 coincides with the center of the rotating block 402 and the fixed block 8. Then, the first cylinder 401 can continue to extend the rotating block 402, so that the rotating block 402 and the fixed block 8 clamp and fix the material plate 10. The first telescopic block 11 and the second telescopic block 14 are completely squeezed into the interior by the rotating block 402 and the fixed block 8. Then, the second cylinder 404 retracts, causing the clamping rod 410 to rotate away from the material plate. Then, the motor 5 can be started. The motor 5 drives the material plate 10 clamped by the rotating block 402 and the fixed block 8 to rotate through the rotating shaft 6.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
