Description

An automatic winding machine wire cutting mechanism Technical Field

[0001] This utility model relates to the field of wire cutting machine technology, specifically to an automatic winding machine wire cutting mechanism. Background Technology

[0002] In the clutch manufacturing process, the winding of the friction plates is a crucial step, affecting the clutch's performance and durability. Traditionally, the process of cutting the windings after winding the clutch friction plates is mostly done manually. This method is not only inefficient but also prone to uneven cutting and damage to the friction plates, impacting the overall quality of the clutch. Furthermore, manual operation poses safety hazards, especially when handling high-speed rotating clutch components. Therefore, this application is hereby submitted. Summary of the Invention

[0003] This application proposes an automatic winding machine wire cutting mechanism to solve the problem that the existing process of cutting the wire after winding clutch friction plates mostly relies on manual operation. This method is not only inefficient but also suffers from uneven wire cutting and damage to the friction plates. The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0004] An automatic winding machine thread cutting mechanism includes a worktable, a needle plate, a support frame, a guide device, a first rodless cylinder, a pneumatic scissor assembly, and a pushing device. The needle plate is disposed on the worktable, the support frame is disposed on one side of the worktable, the guide device is disposed on the support frame, the first rodless cylinder is disposed on the guide device, the pneumatic scissor assembly is disposed on the first rodless cylinder, and the pushing device is disposed on the worktable.

[0005] Furthermore, the feeding device includes a fixed frame, a second rodless cylinder, a connecting rod, and a push rod. The fixed frame is disposed on the worktable, the second rodless cylinder is disposed on the fixed frame, the connecting rod is disposed on the second rodless cylinder, the push rod is disposed on the connecting rod, and the push rod is located on the surface of the needle plate.

[0006] Furthermore, the guiding device includes a slide rail, a slider, and a connecting plate. The slide rail is mounted on the support frame, the slider is slidably mounted on the slide rail, the connecting plate is mounted on the slider, and the connecting plate is connected to the first rodless cylinder.

[0007] Furthermore, the push rod is symmetrically provided with irregularly shaped rods.

[0008] Furthermore, the push rod and the connecting rod are connected by bolts.

[0009] Furthermore, the support frame is provided with a support plate, and the slide rail is disposed on the support plate.

[0010] Compared with the prior art, the beneficial effects of this utility model include:

[0011] The rapid response and precise control of the first and second rodless cylinders enable the pneumatic shear assembly and pushing device to quickly complete the shearing and pushing actions, significantly shortening the operation cycle. The pneumatic shear assembly, driven by pneumatics, avoids the safety hazards that may be caused by direct manual operation of the shears. At the same time, the precise control of the pneumatic shear assembly also reduces the possibility of misoperation, ensures product consistency, and improves the pass rate.

[0012] By setting a push rod, the friction pad after wire cutting will be pushed out through the push rod. The special-shaped rod makes the pushing process stable and reliable, avoiding accidental drop or displacement of materials during the pushing process, thereby ensuring the safety of operation, realizing overall automation, and improving production efficiency.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] Please refer to Figures 1-3. An automatic winding machine wire cutting mechanism includes a worktable 1, a needle plate 2, a support frame 3, a guide device, a first rodless cylinder 4, a pneumatic scissor assembly 5, and a pushing device. The needle plate 2 is disposed on the worktable 1, the support frame 3 is disposed on one side of the worktable 1, the guide device is disposed on the support frame 3, the first rodless cylinder 4 is disposed on the guide device, the pneumatic scissor assembly 5 is disposed on the first rodless cylinder 4, and the pushing device is disposed on the worktable 1.

[0021] The workbench 1 provides a stable foundation for the entire mechanism. The needle plate 2 is used to fix and support the material to be wound. The support frame 3 and the guide device together provide a stable moving path for the first rodless cylinder 4. The pneumatic shear assembly 5 completes the shearing action under the drive of the first rodless cylinder 4. The pushing device is responsible for pushing the sheared material to the next process or collection point.

[0022] In some embodiments, the feeding device includes a fixed frame 6, a second rodless cylinder 7, a connecting rod 8, and a push rod 9. The fixed frame 6 is mounted on the worktable 1, the second rodless cylinder 7 is mounted on the fixed frame 6, the connecting rod 8 is mounted on the second rodless cylinder 7, and the push rod 9 is mounted on the connecting rod 8. The push rod 9 is located on the surface of the needle plate 2. The feeding device is stably mounted on the worktable 1 by the fixed frame 6. The second rodless cylinder 7 serves as a power source, driving the connecting rod 8 and the push rod 9 to reciprocate. When the pneumatic shear assembly 5 completes the shearing action, the second rodless cylinder 7 is activated, driving the push rod 9 to move along the surface of the needle plate 2 via the connecting rod 8, pushing the sheared material to a predetermined position, ensuring the accuracy and stability of the feeding and improving production efficiency.

[0023] In some embodiments, the guiding device includes a slide rail 10, a slider 11, and a connecting plate 12. The slide rail 10 is mounted on the support frame 3, the slider 11 is slidably mounted on the slide rail 10, and the connecting plate 12 is mounted on the slider 11 and connected to the first rodless cylinder 4. The guiding device provides a precise movement path for the first rodless cylinder 4 through the sliding engagement of the slide rail 10 and the slider 11. The slide rail 10 is mounted on the support frame 3, the slider 11 slides freely on the slide rail 10, and the connecting plate 12 is fixed to the slider 11 and connected to the first rodless cylinder 4. Thus, when the first rodless cylinder 4 is activated, it can drive the slider 11 to slide on the slide rail 10 via the connecting plate 12, thereby achieving precise movement and shearing of the pneumatic scissor assembly 5.

[0024] In some embodiments, the push rod 9 is symmetrically provided with irregularly shaped rods 13. These are used to increase the friction and clamping force between the push rod 9 and the material, so as to ensure that the material does not slip or shift during the pushing process.

[0025] In some embodiments, the push rod 9 and the connecting rod 8 are connected by bolts. This connection method is simple, reliable, and easy to maintain and replace. At the same time, the bolt connection also allows for some adjustment of the position and angle of the push rod 9 to accommodate different material specifications or operational requirements.

[0026] In some embodiments, a support plate 14 is provided on the support frame 3, and a slide rail 10 is disposed on the support plate 14. By adjusting the height of the support plate 14 on the support frame 3, the position of the pneumatic scissor assembly 5 for cutting the wire can be adjusted.

[0027] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
