Description
Technical Field
[0001] This utility model relates to the field of pressing machines, and in particular to a cutting mechanism for a fully automatic pressing machine. Background Technology
[0002] In the modern electronics manufacturing and wire harness processing field, fully automated crimping machines, as key equipment for integrating wire harness end crimping and cutting, play a crucial role in improving production efficiency and ensuring connection reliability. With the surge in demand for precision wire harnesses from industries such as automotive electronics, smart homes, and industrial automation, the diversification of wire harness specifications and the continuous improvement in processing precision requirements mean that the performance of fully automated crimping machines directly impacts the quality stability of downstream products. Their core function lies in automating processes such as wire harness feeding, stripping, terminal crimping, and fixed-length cutting, replacing traditional manual operations, significantly reducing human error, and meeting the high efficiency and precision demands of large-scale production. Currently, fully automatic pressing machines mostly employ a single guide rail combined with a cylinder or servo motor for driving and guiding the cutting blade. In common mechanical structures, the cutting blade is usually fixed on a sliding seat, which moves up and down along a single cylindrical or square guide rail, relying on the clearance between the guide rail and the slider for guidance. The technical principle is that the linear power provided by the drive component propels the cutting blade rapidly downwards along the guide rail, using the sharp edge of the blade to cut the wire harness. Some machines apply lubricant to the guide rail surface or use ball bearings as the sliding medium to reduce friction, but the overall guiding structure still primarily relies on a single-path constraint. However, the existing single-rail guiding method has obvious limitations: since the cutting blade is only constrained in one direction during high-speed descent, it is susceptible to slight lateral vibration or swaying caused by the instantaneous impact force of the drive component. This vibration directly causes the contact position between the blade and the wire harness to deviate, resulting in a reduction in the consistency of the wire harness length after cutting. This causes the product to exceed the allowable error range, affecting the quality and efficiency of subsequent assembly processes. Therefore, a cutting mechanism for a fully automatic pressing machine is proposed to solve the above problems. Utility Model Content
[0003] To overcome the above deficiencies, this utility model provides a cutting mechanism for a fully automatic pressing machine, which aims to improve the problem of large length deviation after wire harness cutting caused by slight vibration of the cutting blade during movement.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A cutting mechanism for a fully automatic pressing machine includes a base plate and a wiring harness. The top of the base plate is fixedly connected to a second fixed frame, a first fixed frame, a support frame, and multiple positioning blocks. Multiple transmission rollers are rotatably connected to the top of the support frame. A telescopic cylinder is fixedly connected to the top of the first fixed frame. The output rod of the first telescopic cylinder passes through the first fixed frame and is fixedly connected to a connecting block. A cutting blade is fixedly connected to one side of the connecting block by bolts. A stabilizing component is provided on the outer wall of the cutting blade. The stabilizing component includes multiple sliders located on both sides of the cutting blade. The multiple sliders are fixedly connected to each other on both sides of the connecting block one. The multiple sliders are slidably connected to both sides of the inner wall of the fixing frame one. The inner wall of the fixing frame one is provided with multiple grooves. Each slider has a ball rotatably connected to both sides, and each ball is slidably connected to the inner wall of the groove.
[0005] As a further description of the above technical solution: The second fixed frame, the first fixed frame, and the support frame are located between the first positioning block and are arranged sequentially from one side of the top of the base plate to the other side. The top of the support frame is fixedly connected to multiple second positioning blocks, one of which is fixedly connected between the bottom of the transmission roller and the motor output end at the bottom of the support frame.
[0006] As a further description of the above technical solution: One end of the wire harness is inserted into the internal hole of one side positioning block and passes through the interior of multiple second positioning blocks. It extends outward from the internal hole of the other side positioning block. A support block is fixedly connected to the bottom of the inner wall of the first fixing frame. A groove matching the size of the cutting blade is opened on the top of the support block. A fixing component is provided on the top of the second fixing frame.
[0007] As a further description of the above technical solution: The fixing assembly includes multiple clamping plates located at the top of the second fixing frame. A telescopic cylinder is fixedly connected to the top of the inner wall of the second fixing frame. The output rod of the telescopic cylinder extends through to the top of the second fixing frame and is fixedly connected to a transmission column.
[0008] As a further description of the above technical solution: The top of the second fixing frame is fixedly connected to a fixing shell and multiple side plates, and the outer walls of the multiple side plates are fixedly connected to both sides of the fixing shell.
[0009] As a further description of the above technical solution: A second connecting block is fixedly connected to the top of the transmission column, a push block is fixedly connected to the top of the second connecting block, and cross sliders are fixedly connected to both sides of the push block.
[0010] As a further description of the above technical solution: Each of the cross sliders has a transmission block slidably connected to its outer wall, and each transmission block has a slide plate fixedly connected to both sides. Multiple transmission blocks and slide plates are slidably connected to the inner wall of the fixed shell.
[0011] As a further description of the above technical solution: Each of the transmission blocks is fixedly connected to a clamping plate at its top, and each clamping plate has multiple anti-slip strips fixedly connected to its inner wall.
[0012] This utility model has the following beneficial effects: In this invention, the sliding of the slider on the inner wall of the fixed frame and the rolling of the ball in the groove are used to double limit and guide the downward trajectory of the cutting blade, effectively reducing the friction during the movement, making the cutting action smoother, solving the technical problem that the length deviation of the wire harness after cutting is large due to slight vibration of the cutting blade during movement, enhancing the stability and accuracy of the cutting process, and ensuring the regularity of the cut.
[0013] In this invention, before cutting the wire harness, a telescopic cylinder double-drive transmission mechanism is used to enable the clamping plates on both sides to stably clamp the wire harness. This solves the problem that the wire harness slips due to the cutting blade during the cutting process, which leads to unstable length of the final product. Through this stable clamping and fixing effect, the reliability of the equipment during the processing is enhanced, and the high consistency of the length of the finished wire harness during mass production is guaranteed.

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.
[0017] Reference Figures 1-4 This utility model provides an embodiment of a cutting mechanism for a fully automatic pressing machine, comprising a base plate 1 and a wire harness 7. The top of the base plate 1 is fixedly connected to a second fixing frame 14, a first fixing frame 5, a support frame 26, and multiple positioning blocks 3. The base plate 1 is made of thickened Q235 carbon steel plate, providing a stable and robust mounting base for the entire equipment, ensuring the overall rigidity and stability of the equipment during operation. Multiple transmission rollers 2 are rotatably connected to the top of the support frame 26, which supports the conveying mechanism. The upper portion of the multiple transmission rollers 2 is chrome-plated for smooth conveying of the wire harness 7. Their rotational design, coordinated with the feeding action of the wire harness 7, reduces feeding resistance and ensures the wire harness... 7. Smooth passage effect: The top of the fixed frame 5 is fixedly connected to the telescopic cylinder 6. The fixed frame 5 is made of high-strength aluminum alloy profile and is used to install the cutting components to ensure the accuracy of the cutting action. The telescopic cylinder 6, model MGPM series, at the top serves as the power source to drive the cutting blade 9 to perform reciprocating linear motion in order to cut the wire harness 7. The output rod of the telescopic cylinder 6 passes through the fixed frame 5 and is fixedly connected to the connecting block 8. The cutting blade 9 is fixedly connected to one side of the connecting block 8 by bolts. The cutting blade 9 is made of SKH-9 high-speed tool steel, which has high hardness and wear resistance, and is used to perform the final cutting task. The outer wall of the cutting blade 9 is provided with a stabilizing component. The stabilizing component ensures the stability and directional accuracy of the cutting blade 9 during high-speed descent, effectively preventing cutting deviations caused by vibration. This component includes multiple sliders 11 located on both sides of the cutting blade 9, fixedly connected to both sides of the connecting block 8, and slidably connected to both sides of the inner wall of the fixing frame 5. The sliders 11 slide in conjunction with the inner wall of the fixing frame 5, providing precise linear guidance for the cutting blade 9. The inner wall of the fixing frame 5 has multiple grooves 13. Each slider 11 has rotatably connected to two balls 12 made of Gcr15 bearing steel on both sides. Each ball 12 slides in conjunction with the inner wall of the groove 13, significantly reducing sliding friction and making the cutting action smoother and less strenuous. The fixing frame 24, fixing frame 5, and support frame 26 are located on the positioning block 8. Between 3, and arranged sequentially from one side of the top of the base plate 1 to the other side, the top of the support frame 26 is fixedly connected to multiple positioning blocks 2 4, and the bottom of one of the transmission rollers 2 is fixedly connected to the motor output end at the bottom of the support frame 26. One end of the wire harness 7 is inserted through the internal hole of the positioning block 1 3 on one side and passes through the internal holes of multiple positioning blocks 2 4, and extends outward from the internal hole of the positioning block 1 3 on the other side. These positioning blocks 1 3 and positioning blocks 2 4 work together to accurately guide and position the transmission path of the wire harness 7, ensuring the accuracy of the position of the wire harness 7 before entering the processing area. The bottom of the inner wall of the fixed frame 1 5 is fixedly connected to a support block 10. The top of the support block 10 is provided with a groove that matches the size of the cutting blade 9. The support block 10 is used to support the wire harness 7 at the moment of cutting to prevent it from deforming and to ensure the flatness of the cut. The groove at the top provides room for the cutting blade 9 to fall. The top of the fixed frame 2 14 is provided with a fixing component.
[0018] Reference Figure 2 , Figure 5 and Figure 6The fixing component is used to reliably clamp and fix the wire harness 7 before cutting, preventing the wire harness 7 from sliding or shifting under the cutting force, thereby ensuring the consistency of the final product length. The component includes multiple clamping plates 23, which are located at the top of the fixing frame 14. A telescopic cylinder 15 is fixedly connected to the top of the inner wall of the fixing frame 14. The telescopic cylinder 15, which is an SMC series thin cylinder, serves as the actuator of the clamping mechanism, providing stable and controllable clamping power. The output rod of the telescopic cylinder 15 extends through to the top of the fixing frame 14 and is fixedly connected to a transmission column 17. A fixing shell 16 and multiple side plates 25 are fixedly connected to the top of the fixing frame 14. The outer walls of the multiple side plates 25 are fixedly connected to both sides of the fixing shell 16. The side plates 25 cooperate with the fixing shell 16 for support, achieving the effect of enhancing the overall structural strength of the fixing component. A connecting block 18 is fixedly connected to the top of the transmission column 17. A push block 19 is fixedly connected to the top of the connecting block 18. A cross slider 20 is fixedly connected to both sides of the push block 19. The push block 19 moves linearly in conjunction with the cross sliders 20 on both sides, achieving the effect of synchronously and evenly transmitting the single thrust of the telescopic cylinder 15 to the transmission mechanism on both sides. A transmission block 21 is slidably connected to the outer wall of each cross slider 20. A slide plate 22 is fixedly connected to both sides of each transmission block 21. Multiple transmission blocks 21 and slide plates 22 are slidably connected to the inner wall of the fixed shell 16. The transmission blocks 21 slide in conjunction with the grooves on the inner wall of the fixed shell 16, achieving the effect of guiding the clamping plate 23 to perform precise and synchronous opening and closing movements. A clamping plate 23 is fixedly connected to the top of each transmission block 21. Multiple anti-slip strips 24 are fixedly connected to the inner wall of each clamping plate 23. These anti-slip strips 24, made of high wear-resistant rubber, are used to increase the contact friction with the wire harness 7, achieving a more secure and reliable clamping effect and preventing the wire harness 7 from slipping.
[0019] Working principle: During the fixing of wire harness 7, the motor at the bottom of support frame 26 drives one of the transmission rollers 2 to rotate, thereby guiding the wire harness 7 to move. When the wire harness 7 moves to one side of the fixing frame 5, the pre-programmed control of the equipment stops the motor and other conveying components at the bottom of support frame 26, keeping the wire harness 7 stationary. Then, the telescopic cylinder 15 is activated, and the output end of the telescopic cylinder 15 drives the push block 19 at the top of the transmission column 17 to move. The cross sliders 20 on both sides of the push block 19 guide the transmission blocks 21 and the sliding plate 22 on both sides to slide on the inner wall of the fixing shell 16. The groove on the inner wall of the fixing shell 16 limits the movement direction of the transmission blocks 21 and the sliding plate 22. The distance between the clamping plates 23 on both sides is controlled by adjusting the movement distance of the push block 19. The clamping plates 23 on both sides are used to fix the wire harness 7. The clamping and fixing prevents the wire harness 7 from slipping due to the cutting blade 9 during the cutting process, which could lead to unstable length. Next, the wire harness 7 needs to be cut. The output end of the telescopic cylinder 6 drives the connecting block 8 and the cutting blade 9 to move downward. During this process, the slider 11 slides on both sides of the inner wall of the fixed frame 5, and the ball 12 rolls on the inner wall of the groove 13 to reduce the friction of the cutting blade 9 moving downward. The sliding of the slider 11 and the ball 12 on both sides of the inner wall of the fixed frame 5 limits the movement direction of the cutting blade 9, preventing the cutting blade 9 from vibrating slightly during downward movement, which could lead to a large deviation in the length of the cut wire harness 7. After the cutting is completed, the pre-programmed control system at the bottom of the support frame 26 and other conveying components continue to operate, facilitating subsequent repeated processing.
