Description

Technical Field

[0001] This utility model relates to the field of processing and manufacturing technology, and more specifically, to a positioning fixture for a football melting machine. Background Technology

[0002] The stacked melting machine is a device used for melting plastic processing. It can generate high-frequency electromagnetic field waves that cause the load ions to react. When melting and cutting the edges of soccer ball material, some parts of the device place multiple hexagonal molds on the top of the soccer ball material. High stability and precision are required during the melting process.

[0003] The existing high-frequency stacked welding machine is prone to mold shaking during the marking and welding process of soccer ball materials, resulting in wrinkles on the finished product, which affects the product's appearance and service life.

[0004] A search revealed a stacked melting machine disclosed in Chinese Patent Publication No. CN220638247U. This utility model fixes the soccer material mold according to its size, and the card can only move up and down under the limit of two rotating rods. The card drives the mold to press the soccer material, thereby reducing the displacement of the soccer material mold during the melting process, which would cause wrinkles in the finished product, improve the pass rate and protect the service life of the product.

[0005] However, in actual use, the aforementioned fusing machine cannot apply uniform clamping force to the soccer ball material when clamping and positioning different models of soccer ball material. This can lead to unevenness of the soccer ball material during clamping, affecting the accuracy of subsequent fusing of the soccer ball material. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a positioning clamp for a football melting machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A positioning fixture for a football fuser includes a base frame, with the fuser body fixedly connected to the top of the base frame. A chassis is slidably connected to the top of the base frame, and a clamping mechanism is provided on the top of the chassis. The clamping mechanism includes a top frame, the lower surface of which is fixedly connected to the top of the chassis. A rotating ring is rotatably connected to the inner side of the top frame, and multiple toothed grooves are formed on the outer side of the rotating ring. A servo motor is fixedly connected to the lower surface of the top frame, and a gear is fixedly connected to the output end of the servo motor. One side of the gear meshes with the inner side of the toothed groove. Multiple transmission rods are fixedly connected to the outer side of the rotating ring. One end of the moving rod is hinged to an arc-shaped arm, and a guide groove is provided on the inner side of the arc-shaped arm. Multiple guide rods are fixedly connected to the top of the top frame. The inner side of the guide groove is slidably connected to the outer side of the guide rod. A positioning frame is fixedly connected to one end of the arc-shaped arm. A pad is fixedly connected to one side of the positioning frame. An electric push rod is fixedly connected to the inner side of the positioning frame. A pressure block is fixedly connected to the bottom end of the electric push rod. A cylinder is fixedly connected to the upper surface of the chassis. The outer side of the cylinder passes through the inner side of the rotating ring and extends to the top of the top frame. A push plate is fixedly connected to the top end of the cylinder. A conveying and positioning mechanism is provided on the outer side of the chassis.

[0009] By adopting the above technical solution: using the deflection of multiple transmission rods and arc arms, combined with the guidance of the guide rod to guide the guide groove, the multiple arc arms can drive the corresponding pads and pressure blocks to expand and contract. Then, combined with the electric push rod to push the pressure block, the edges of different models of soccer ball materials are clamped and positioned at multiple points. Then, the lower surface of the soccer ball material after positioning is pushed by the cylinder and push plate to keep the soccer ball material flat after positioning.

[0010] As a further description of the above technical solution: the conveying and positioning mechanism includes two threaded pushers. One side of the threaded pusher is fixedly connected to the outer side of the chassis, and the outer side of the threaded pusher is slidably connected to the inner side of the chassis. Two springs are fixedly connected to the inner side of the chassis, and a locking block is fixedly connected to the bottom end of each spring. The outer side of the locking block is slidably connected to the inner side of the chassis. Two servo motors are fixedly connected to one side of the chassis. A lead screw is fixedly connected to the output end of each servo motor. The outer side of the lead screw is threadedly connected to the inner side of the threaded pusher. Two locking holes are opened on the upper surface of the chassis.

[0011] By adopting the above technical solution: using two servo motors and lead screws to provide uniform driving force to the chassis and top frame, and using two springs to push the locking block to lock and limit the locking holes on the surface of the chassis, the football material remains stable during the melting process.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a clamping mechanism, compared with the existing technology, the synchronous expansion and contraction of multiple transmission rods and arc arms are used to adapt to the surface of football materials of different sizes and slight deformations. Combined with the multi-point clamping of multiple pads and pressure blocks and the support of cylinders and push plates for the football material, a uniform support force and constraint force are provided to the football material, avoiding excessive local stress that could damage the ball surface, and maintaining the flatness of the surface when the football material melts, thus improving the accuracy of the football material melting.

[0014] 2. By setting up a conveying and positioning mechanism, compared with the existing technology, two lead screws are used to convey the chassis and the top frame, so that the soccer ball material remains stable during the conveying process. Two locking blocks are used to quickly lock and limit the chassis, top frame and soccer ball material after movement, so as to maintain the stability of the soccer ball material cutting.

The clamping mechanism includes a top frame 4, the lower surface of which is fixedly connected to the top of the chassis 3. A rotating ring 5 is rotatably connected to the inner side of the top frame 4, and multiple toothed grooves 6 are formed on the outer side of the rotating ring 5. A servo motor 7 is fixedly connected to the lower surface of the top frame 4, and a gear 8 is fixedly connected to the output end of the servo motor 7. One side of the gear 8 meshes with the inner side of the toothed groove 6. Multiple transmission rods 9 are fixedly connected to the outer side of the rotating ring 5, and one end of each transmission rod 9 is hinged to an arc-shaped... Arm 10, with a guide groove 11 on the inner side of the arc-shaped arm 10, and multiple guide rods 12 fixedly connected to the top of the top frame 4. The inner side of the guide groove 11 is slidably connected to the outer side of the guide rods 12. A positioning frame 13 is fixedly connected to one end of the arc-shaped arm 10. A pad 14 is fixedly connected to one side of the positioning frame 13. An electric push rod 15 is fixedly connected to the inner side of the positioning frame 13. A pressure block 16 is fixedly connected to the bottom end of the electric push rod 15. A cylinder 17 is fixedly connected to the upper surface of the chassis 3. The outer side of the cylinder 17 passes through the inner side of the rotating ring 5 and extends to the top of the top frame 4. A push plate 18 is fixedly connected to the top end of the cylinder 17. A conveying and positioning mechanism is provided on the outer side of the chassis 1.

[0024] The servo motor 7 and gear 8 engage the toothed groove 6 on the outer side of the rotating ring 5, allowing the rotating ring 5 to drive multiple transmission rods 9 and arc-shaped arms 10 to deflect. Then, multiple guide rods 12 slide and guide the guide groove 11 on the inner side of the arc-shaped arms 10, allowing the multiple arc-shaped arms 10 to drive the corresponding positioning frame 13 to expand and contract to align the edges of different types of soccer ball materials. Then, the electric push rod 15 pushes the pressure block 16, so that the edge of the soccer ball material is clamped by multiple pressure blocks 16 and pads 14, keeping the soccer ball material in a stable position. Finally, the cylinder 17 and push plate 18 push the soccer ball material to keep it flat after positioning.

[0025] Reference Figure 2 , Figure 3 and Figure 5As shown, the conveying and positioning mechanism includes two threaded pushers 19. One side of the threaded pusher 19 is fixedly connected to the outer side of the chassis 3, and the outer side of the threaded pusher 19 is slidably connected to the inner side of the chassis 1. Two springs 20 are fixedly connected to the inner side of the chassis 3. A locking block 21 is fixedly connected to the bottom end of the spring 20. The outer side of the locking block 21 is slidably connected to the inner side of the chassis 3. Two servo motors 22 are fixedly connected to one side of the chassis 1. A lead screw 23 is fixedly connected to the output end of the servo motor 22. The outer side of the lead screw 23 is threadedly connected to the inner side of the threaded pusher 19. Two locking holes are opened on the upper surface of the chassis 1. The two lead screws 23 are used to drive the two threaded pushers 19 and the chassis 3 by thread. Then, the two springs 20 at the bottom of the chassis 3 push the locking block 21 to lock and limit the locking holes on the surface of the chassis 1, so that the chassis 3 and the top frame 4 can quickly position the football material under the fuser body 2.

[0026] The working principle of this utility model is as follows: When melting the soccer ball material, the cut soccer ball material is first placed above the push plate 18. Based on the diameter of the soccer ball material, the servo motor 7 drives the gear 8 to mesh with the toothed groove 6 on the outer side of the rotating ring 5, causing the rotating ring 5 to drive multiple transmission rods 9 and arc-shaped arms 10 to deflect. Then, using the sliding guidance of the guide groove 11 on the inner side of the arc-shaped arm 10 and the multiple guide rods 12 corresponding to the top of the top frame 4, the multiple arc-shaped arms 10 contract inward or expand outward under the guidance of the guide rods 12. Afterward, the edge of the soccer ball material is placed on top of multiple pads 14. Then, multiple electric push rods 15 are activated to extend, causing the electric push rods 15 to drive the pressure block 16 to press and position the soccer ball material placed on top of the pad 14 at multiple points. Simultaneously, the servo motor 7 and gear 8 continuously rotate the rotating ring 5. The meshing transmission causes multiple transmission rods 9 and arc-shaped arms 10 to drive the corresponding pads 14, electric push rods 15 and pressure blocks 16 to expand and fix the soccer ball material. Then, the cylinder 17 is activated to push the push plate 18 to support the lower surface of the soccer ball material at a certain height, so that the soccer ball material remains flat after being positioned and expanded. After that, two servo motors 22 are activated to drive the lead screw 23 to drive the two threaded pushers 19 to move the chassis 3, top frame 4 and soccer ball material to the bottom of the fuser body 2. After the chassis 3 moves to the bottom of the fuser body 2, the two springs 20 inside the chassis 3 push the locking block 21 to engage and limit the locking hole on the surface of the chassis 1, so that the chassis 3 and top frame 4 remain fixed during the melting process of the soccer ball material, and finally the melting of the soccer ball material is completed.
