Description

Technical Field

[0001] This utility model relates to the field of leather cutting, and more specifically, to an adjustable-size electric vehicle seat leather cutting device. Background Technology

[0002] Against the backdrop of the booming development of the electric vehicle industry, the production scale of electric vehicle seat cushions is constantly expanding. As one of the links in the seat cushion production process, the quality of leather cutting directly affects product quality and production efficiency.

[0003] In the prior art, such as Chinese patent "CN221421135U", a "cowhide defect identification and cutting device" is proposed, which includes a cutting table, a machine body fixedly connected to the rear side of the top of the cutting table, a moving rod slidably connected to the top of the cutting table, a maintenance mechanism provided at the bottom of the moving rod, and support columns fixedly connected to the hexagonal corners of the bottom of the cutting table; the maintenance mechanism includes a maintenance blanket, several oil outlet holes and an oiling pipe, the inside of the maintenance blanket is rotatably connected to the surface of the oiling pipe, the oil outlet holes are opened on the surface of the oiling pipe, and the surface of the oil outlet holes is in contact with the inner wall of the maintenance blanket.

[0004] However, the aforementioned patents lack an effective pressing and fixing structure for the leather during cutting. The leather is prone to displacement due to external forces during the cutting process, causing the cutting trajectory to deviate from the preset path. This is especially true for softer or larger electric vehicle seat leather, which can easily lead to problems such as edge skewing and size deviation, thus affecting product consistency.

[0019] 3. Beneficial effects

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] (1) In this solution, the sliding fit between the mounting frame and the fixing frame and the leather placement plate can adjust the fixing range according to the size of the leather; the No. 1 pressing rod and the No. 2 pressing rod adopt a vertical cross sliding design, which, together with the elastic telescopic structure of the pressing block, can form a pressing area that covers all directions in the horizontal direction, and is suitable for various electric vehicle seat leather sizes from small to large.

[0022] (2) In this scheme, when the No. 1 pressing rod and the No. 2 pressing rod slide relative to each other, the inner wall of the No. 1 pressing rod squeezes the pressing block to compress the spring and slide. After the adjustment is completed, the spring resets and pushes the pressing block to keep the bottom surface of the No. 1 pressing rod at the same level, forming a uniform pressing without gaps, avoiding leather wrinkles or loosening caused by uneven force.

[0023] (3) In this scheme, the mounting frame achieves smooth lifting and positioning through the symmetrical transmission of the bidirectional screw and the connecting rod. Combined with the self-locking characteristics of the threaded transmission structure, it ensures that the fixed position does not shift during the cutting process, providing a stable working benchmark for the cutting head and effectively ensuring the flatness and dimensional accuracy of the cutting edge.

[0036] In some embodiments, please refer to Figure 1-7An adjustable-size electric vehicle seat leather cutting device includes a base 1, a support frame 11 fixedly connected to the top of the base 1, a fixing frame 12 and a leather placement plate 14 fixedly connected to the top of the support frame 11, a square groove 13 formed in the middle of the fixing frame 12, the leather placement plate 14 located inside the square groove 13, a mounting frame 10 slidably connected inside the square groove 13, the inner and outer walls of the mounting frame 10 slidably connected to the outer wall of the leather placement plate 14 and the inner wall of the fixing frame 12, two primary pressing rods 15 slidably connected inside the mounting frame 10, and two secondary pressing rods 15 slidably connected inside the two primary pressing rods 15. 6. Both ends of the two No. 2 pressing rods 16 are slidably connected to the inside of the mounting frame 10. The sliding direction of the No. 1 pressing rod 15 is perpendicular to the sliding direction of the No. 2 pressing rod 16. Multiple pressing blocks 18 are slidably connected inside the No. 2 pressing rod 16. The bottom surface of the pressing block 18 and the bottom surface of the No. 1 pressing rod 15 are on the same horizontal plane. A spring 17 is fixedly connected between the pressing block 18 and the inside of the No. 2 pressing rod 16. Rounded corners are provided on both sides of the pressing block 18. A No. 1 handle 19 is fixedly connected above the two No. 1 pressing rods 15. A No. 2 handle 2 is fixedly connected to one end of the two No. 2 pressing rods 16 located outside the mounting frame 10.

[0037] In this embodiment, the position range of the mounting frame 10 can be adjusted according to the size of the leather by sliding the mounting frame 10 with the fixing frame 12 and the leather placement plate 14. The first pressing rod 15 and the second pressing rod 16 adopt a vertical sliding design, which can realize multi-dimensional adjustment in the horizontal direction. The two first pressing rods 15 can slide laterally along the mounting frame 10, and the two second pressing rods 16 can slide longitudinally along the mounting frame 10. The second pressing rods 16 are inserted inside the first pressing rods 15 to form a cross-pressing structure, which can adapt to different specifications of electric vehicle seat leather and solve the problem of single size and poor adaptability of traditional fixing devices.

[0038] The pressing block 18 is elastically connected to the second pressing rod 16 via a spring 17. The pressing block 18 extends the bottom surface of the second pressing rod 16, keeping it flush with the bottom surface of the first pressing rod 15. Crucially, when the first pressing rod 15 and the second pressing rod 16 slide relative to each other, the inner wall of the first pressing rod 15 presses against the pressing block 18, causing it to slide as well. This dynamic adaptation structure ensures both the continuity and uniformity of the pressing action, while avoiding gaps caused by relative movement. This effectively ensures that the leather fits tightly against the leather placement plate 14 during the cutting process, preventing displacement due to loosening and ensuring cutting accuracy. The distribution of multiple pressing blocks 18 further enhances the comprehensiveness of the pressing action. Combined with the sliding limit of the mounting frame 10 and the fixed frame 12, this ensures that the leather remains stable within the cutting area.

[0039] The No. 1 handle 19 above the No. 1 pressing lever 15 and the No. 2 handle 2 at the end of the No. 2 pressing lever 16 provide convenient gripping and force application points for operators, facilitating quick adjustment of the pressing position.

[0040] In some embodiments, please refer to Figure 1-7 An adjustable-size electric vehicle seat leather cutting device includes a bidirectional screw 21 rotatably connected to the lower part of a support frame 11. Moving blocks 22 are threadedly connected to both sides of the outer wall of the bidirectional screw 21. Connecting rods 23 are rotatably connected to both ends of each of the two moving blocks 22. The ends of the four connecting rods 23 furthest from the moving blocks 22 are rotatably connected to the lower part of a mounting frame 10. A first-generation motor 24 is fixedly connected to the outside of the support frame 11. The output end of the first-generation motor 24 is fixedly connected to one end of the bidirectional screw 21. First-generation threaded rods 25 are rotatably connected to both sides of a fixed frame 12. The outer wall of the 25 is threadedly connected to a movable frame 26. The fixed frame 12 is externally fixedly connected to two No. 2 motors 3. The output ends of the two No. 2 motors 3 are respectively fixedly connected to one end of two No. 1 threaded rods 25. The movable frame 26 is internally rotatably connected to a No. 2 threaded rod 27. The movable frame 26 is externally fixedly connected to a No. 3 motor 31. The output end of the No. 3 motor 31 is fixedly connected to one end of the No. 2 threaded rod 27. The outer wall of the No. 2 threaded rod 27 is threadedly connected to an electric cylinder 28. The electric cylinder 28 and the movable frame 26 are internally slidably connected. The output end of the electric cylinder 28 is equipped with a cutting head 29.

[0041] In this embodiment, the support frame 11 is driven by a first motor 24 to rotate a bidirectional screw 21, which in turn drives the two moving blocks 22 on both sides to move synchronously in opposite directions. Then, the height and horizontal position of the mounting frame 10 are stably adjusted by the connecting rod 23 to achieve precise positioning of the leather placement area and avoid errors from manual adjustment. The second motor 3 on both sides of the fixed frame 12 drives the first threaded rod 25 to rotate, so that the moving frame 26 moves smoothly in the horizontal direction. In conjunction with the third motor 31 inside the moving frame 26 driving the second threaded rod 27 to drive the electric cylinder 28 to slide laterally, the cutting head 29 can move precisely in the two-dimensional plane, ensuring that the cutting trajectory matches the preset size and solving the problem of insufficient precision in traditional manual cutting.

[0042] The automated drive of motor 24, motor 3, and motor 31 replaces the traditional manual adjustment method, reducing the time cost and physical exertion of manual operation. The electric cylinder 28 can quickly drive the cutting head 29 to complete the vertical cutting action. With the smooth operation of each transmission structure, the cutting cycle of a single piece of leather is greatly shortened. At the same time, the threaded transmission structure has self-locking properties, which can maintain a stable position during the cutting process and avoid cutting interruption due to external interference, effectively improving the stability and efficiency of continuous production.

[0043] Working principle: This device is powered by an external power supply. First, the leather of the electric vehicle seat cushion to be cut is laid flat on the leather placement plate 14. The leather placement plate 14 is located in the square groove 13 in the middle of the fixed frame 12, providing a stable bearing base for the leather. The bidirectional screw 21 is driven to rotate by the No. 1 motor 24. The moving blocks 22 on both sides of the outer wall of the bidirectional screw 21 move synchronously in opposite directions due to the threaded connection. The connecting rods 23 connected to both ends of the moving blocks 22 push or pull the mounting frame 10, so that the mounting frame 10 slides along the inner wall of the fixed frame 12 and the outer wall of the leather placement plate 14, thereby adjusting the position of the mounting frame 10 in the square groove 13 and ensuring that the area of ​​the leather to be cut is within the working range of the cutting head 29.

[0044] After the position of the mounting frame 10 is determined, push the two No. 1 pressing rods 15 laterally along the mounting frame 10 by the No. 1 handle 19, and at the same time push the two No. 2 pressing rods 16 longitudinally along the mounting frame 10 by the No. 2 handle 2. The sliding direction of the No. 1 pressing rod 15 and the No. 2 pressing rod 16 is perpendicular, and the No. 2 pressing rod 16 passes through the inside of the No. 1 pressing rod 15. During the sliding process, when the No. 1 pressing rod 15 and the No. 2 pressing rod 16 move relative to each other, the inner wall of the No. 1 pressing rod 15 squeezes the pressing block 18, so that the pressing block 18 slides inside the No. 2 pressing rod 16 and compresses the spring 17. After adjusting to the position that matches the size of the leather, the spring 17 returns to its original position and pushes the pressing block 18 to extend downward, keeping it at the same level as the bottom surface of the No. 1 pressing rod 15, so that they can work together to form a uniform pressure on the leather, and firmly fix the leather on the leather placement plate 14 to prevent displacement during cutting.

[0045] After the cutting parameters are set, motor 3 starts and drives the first threaded rod 25 on both sides of the fixed frame 12 to rotate. The moving frame 26, which is threaded to the first threaded rod 25, moves smoothly in the horizontal direction, realizing the position adjustment of the cutting head 29 in the longitudinal direction. At the same time, motor 31 outside the moving frame 26 drives the second threaded rod 27 inside to rotate. The electric cylinder 28, which is threaded to the second threaded rod 27, slides along the inside of the moving frame 26, completing the movement adjustment of the cutting head 29 in the lateral direction. Through the vertical transmission cooperation between the first threaded rod 25 and the second threaded rod 27, the cutting head 29 can be accurately positioned to the starting point of the preset cutting trajectory in the two-dimensional plane.

[0046] When the cutting head 29 reaches the cutting starting point, the electric cylinder 28 starts and drives the cutting head 29 to move vertically downward, contact the leather and complete the cutting action. During the cutting process, each motor continuously drives the transmission structure to move the cutting head 29 along the preset trajectory. At the same time, the first pressing rod 15, the second pressing rod 16 and the pressing block 18 maintain stable pressure on the leather. The self-locking property of the threaded transmission structure ensures that the cutting head 29 and the mounting frame 10 do not shift position during the cutting process until the cutting of the entire piece of leather is completed.

[0047] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
