Description

Technical Field

[0001] This invention relates to the field of bare copper cutting and shaping technology, specifically to a cutting composite device with shaping function. Background Technology

[0002] The manufacturing process of Haripin motors includes the forming and cutting of hairpin wires and the subsequent insulation coating of bare copper. After the hairpin wires are cut by a cutting tool, the edges of the bare copper have sharp burrs. During the subsequent coating process, the coating layer at these burrs will have sharp, stringy burrs, similar to the stress concentration characteristics of a shaft. The tiny size leads to huge performance degradation. Haripin motors have extremely high slot fill factor, so the solder joints of the hairpin wire harness are very close together. The sharp coating burrs will stick together. This microscopic stress concentration feature can cause stress fatigue during high-speed motor operation, leading to coating peeling, insulation failure, and the risk of motor fire.

[0003] To address the issue of coatings sticking together at different solder joints, existing production technologies primarily improve the production process. One approach is to increase the amount of copper wire removed, i.e., cut off more copper wire. Another approach is to reduce the thickness of the coating layer to reduce coating stringing.

[0004] However, these methods all have obvious drawbacks. Increasing the amount of varnish removed from the copper wire will lead to material waste and affect the welding quality. Reducing the coating thickness will reduce the insulation performance and fail to meet the high standard motor operation requirements. Existing technologies can only reduce the degree of coating wire adhesion, but cannot fundamentally eliminate this phenomenon. Moreover, in mass production, the adjustment of process parameters cannot adapt to the uncertain fluctuations in production.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing device structure. Summary of the Invention

[0006] The purpose of this invention is to provide a cutting composite device with shaping function to solve the problems mentioned in the background art, which can only reduce the degree of coating layer stringing and adhesion, but cannot fundamentally eliminate this phenomenon, and in mass production, the adjustment of process parameters cannot adapt to the uncertain fluctuation factors of production.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cutting composite device with shaping function, comprising an upper chamfering mechanism, a lower chamfering mechanism, a cutting mechanism, and a cutting tool; The upper end of the base plate is provided with a support, and the upper end of the support is provided with an upper pressure seat and a lower pressure seat. The upper pressure seat is located above the lower pressure seat, and a cutting blade is provided in the guide groove inside the upper pressure seat and the lower pressure seat. The cutting tool, acting as the actuator, is located at the center of the lower part of the mechanism. Its working principle is that the cutting tool passes through the guide grooves of the upper and lower wire clamping seats, which clamp the copper wire from both directions. The copper wire pressing chamfering mechanism, the lower chamfering mechanism, and the cutting mechanism act as the driving mechanism, surrounding the cutting tool and arranged in parallel.

[0008] Preferably, the copper wire cutting mechanism includes a vertical motor, a reducer, a cutting shaft, and a connecting rod. The reducer is installed on the outside of the support, and the input end of the reducer is connected to the output end of the vertical motor. The output end of the reducer is equipped with a cutting shaft, and the end of the cutting shaft away from the reducer is connected to a connecting rod.

[0009] Preferably, the copper wire cutting mechanism further includes a connecting seat, a cutting blade, a guide shaft, a spring, a clamp, a pin, and a connecting block. The connecting seat is installed inside the support and is located at the upper end of the cutting blade. Meanwhile, two sets of guide shafts are fixedly installed inside the support.

[0010] Preferably, the spring and the clamp are sleeved on the outside of the guide shaft, with the spring located at the upper end of the clamp. The first pin is located in the middle of the support and between the two sets of connecting seats. The connecting block inside the support is located at the lower end of the first pin. The vertical motor drives the eccentric cutting shaft to rotate, thereby causing the connecting block connected to the cutting blade to reciprocate up and down in the guide groove of the connecting seat.

[0011] Preferably, the copper wire pressing and chamfering mechanism includes a horizontal motor, a second reducer, a pressing shaft, a first gear, a second gear, and an outer sliding seat. The second reducer is located on the upper end of the support away from the first reducer, and the input end of the second reducer is connected to the output end of the horizontal motor.

[0012] Preferably, the output end of the reducer is equipped with a clamping shaft, and gear one and gear two are provided on the outer side of the clamping shaft, with gear one located at the upper end of gear two, and the outer sliding seat is provided at the lower end of the support.

[0013] Preferably, the copper wire pressing and chamfering mechanism further includes a double-row cylindrical roller bearing, a cylindrical roller bearing I, a cylindrical roller bearing II, an angular contact ball bearing I, a transmission seat I, and a transmission seat II, with the double-row cylindrical roller bearing rotatably mounted on one end of the support near the reducer II, and the cylindrical roller bearing I mounted on the upper end of the support.

[0014] Preferably, the cylindrical roller bearing 2 is installed on the outer side of the support away from the gear 2, and the angular contact ball bearing 1 is rotatably installed on the outer side of the support near the gear 2. The transmission seat 1 and transmission seat 2 are respectively located on the outer side of the shaft pin 2 and shaft pin 3 inside the support. The transverse motor drives the eccentric pressing shaft to rotate, which is transmitted to the gear 2, driven shaft 1, and the eccentric driven shaft 1 in sequence, so that the outer sliding seat connected to the lower pressure seat moves up and down in the guide groove of the support.

[0015] Preferably, the support is provided with a driven shaft one, a driven shaft two, and a gear three inside, with driven shaft one located at the lower end of driven shaft two, and gear three located at the lower end of driven shaft two.

[0016] Preferably, the support is internally provided with an angular contact ball bearing II, a cylindrical roller bearing III, and an inner sliding seat. The angular contact ball bearing II and the cylindrical roller bearing III are located on the upper and lower sides of the driven shaft II, respectively, and the inner sliding seat is located at the lower end of the transmission seat II. The eccentric driven shaft II rotates, thereby causing the inner sliding seat connected to the upper pressure seat to reciprocate up and down in the guide groove of the outer sliding seat.

[0017] Compared with the prior art, the beneficial effects of this invention are: the four chamfers of the copper wire can be pressed tightly before cutting, and the edges are directly shaped by the pressing force, so that the quadrilateral copper wire becomes an octagon, thereby fundamentally eliminating the adhesion burrs in the coating process and improving the life of the motor at the end. The device achieves integrated operation of shaping and cutting through a unique structural design, which greatly improves production efficiency, effectively reduces the defect rate in subsequent processes, and lowers production costs. Each component of the device is precision-machined and strictly assembled to ensure the stability and reliability of operation.

[0018] 1. The process of shaping the copper wire by extruding its edges and then cutting it with a tool solves the problem of burrs on the solder joint coating. This effectively avoids the generation of sharp, stringy burrs on the coating layer, thus significantly improving insulation performance. The combination of shaping and cutting not only optimizes the geometry of the copper wire but also provides a more ideal surface condition for subsequent coating processes.

[0019] 2. The drive part of the cutting mechanism and the drive part of the chamfering mechanism are arranged side by side. The execution part of the cutting mechanism is in the form of a sliding block, and the execution part of the chamfering mechanism is in the form of a sliding groove. The two cooperate with each other.

[0020] 3. The driving power of the pressing chamfering mechanism is directly connected in series to the driving mechanism of the pressing chamfering mechanism. The power transmission scheme is a series connection of three gears. The first gear driven by the motor meshes with the gear of the pressing chamfering mechanism, and the gear of the pressing chamfering mechanism meshes with the gear of the pressing chamfering mechanism.

[0021] 4. For the pressing chamfering mechanism and the pressing chamfering mechanism, the opposing transmission between the gears realizes the opposing movement of the upper pressing seat and the lower pressing seat. The transmission seat connected to the upper pressing seat is in the form of a sliding groove, and the transmission seat connected to the lower pressing seat is in the form of a sliding block. The two cooperate with each other.

[0022] 5. The cutting mechanism is driven by a motor that drives the eccentric shaft to rotate, so that the cutting blade completes the punching action in an accelerated manner. In order to make the mechanism rigid while cutting at high speed, the guide seat of the blade is matched with two large guide shafts. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1: In a specific embodiment, the present invention provides the following technical solution: a cutting composite device with shaping function, such as... Figure 1 - Figure 7 The basic working process of the device is shown in the figure.

[0027] The system includes an upper chamfering mechanism, a lower chamfering mechanism, a cutting mechanism, and a cutting tool. A support 28 is located at the upper end of the base plate 29, and an upper wire pressing seat 10 and a lower wire pressing seat 11 are located at the upper end of the lower wire pressing seat 11. A cutting tool 6 is installed in the guide grooves inside the upper and lower wire pressing seats 10 and 11. The cutting tool, acting as the actuator, is located at the center of the lower part of the mechanism. Its working principle is that the cutting tool 6 passes through the guide grooves of the upper and lower wire pressing seats 10 and 11, clamping the copper wire from both directions. The upper chamfering mechanism, lower chamfering mechanism, and cutting mechanism serve as the driving mechanism, surrounding the cutting tool and arranged in parallel. The copper wire cutting mechanism includes a vertical motor 1, a reducer 2, a cutting shaft 3, and a connecting rod 4. The reducer 2 is installed outside the support 28, and its input end is connected to the vertical motor. The output end of motor 1 is connected, and the output end of reducer 2 is equipped with a cutting shaft 3. At the same time, the end of the cutting shaft 3 away from reducer 2 is connected to a connecting rod 4. The copper wire cutting mechanism also includes a connecting seat 5, a cutting blade 6, a guide shaft 7, a spring 8, a clamp 9, a pin 30, and a connecting block 33. The connecting seat 5 is installed inside the support 28 and is located at the upper end of the cutting blade 6. At the same time, two sets of guide shafts 7 are fixedly installed inside the support 28. The spring 8 and the clamp 9 are sleeved on the outside of the guide shaft 7, and the spring 8 is located at the upper end of the clamp 9. The pin 30 is located in the middle position of the support 28 and is located between the two sets of connecting seats 5. The connecting block 33 is located at the lower end of the pin 30 inside the support 28. The vertical motor 1 drives the eccentric cutting shaft 3 to rotate, so that the connecting block 33 connected to the cutting blade 6 moves up and down in the guide groove of the connecting seat 5.

[0028] When using this cutting composite device with shaping function, the vertical motor 1 is started first. Through the transmission of the reducer 2, the cutting shaft 3 is driven to rotate eccentrically. This eccentric rotation is transmitted to the connecting block 33 through the connecting rod 4, so that the cutting blade 6 moves up and down in the guide groove. At the same time, the horizontal motor 12 drives the clamping shaft 14 to rotate through the reducer 13. The movement of the clamping shaft 14 is transmitted to the driven shaft 17 and driven shaft 18 through the gear set, which respectively drive the outer sliding seat 20 and the inner sliding seat 21 to move in opposite directions. With the cooperation of the outer sliding seat 20 and the inner sliding seat 21, the upper wire clamping seat 10 and the lower wire clamping seat 11 can accurately clamp the copper wire and shape the edges of the copper wire. Throughout the process, the design of the guide shaft 7 and the spring 8 ensures the stability of the mechanism, while the setting of angular contact ball bearings and cylindrical roller bearings effectively reduces the friction loss between components and improves the overall service life of the device.

[0029] Example 2: In one specific embodiment, such as Figure 1 - Figure 7 The process of using this device to stably chamfer bare copper is shown in the figure.

[0030] The copper wire pressing and chamfering mechanism includes a horizontal motor 12, a second reducer 13, a clamping shaft 14, a first gear 15, a second gear 16, and an outer sliding seat 20. The second reducer 13 is located on the upper end of the support 28 away from the first reducer 2, and its input end is connected to the output end of the horizontal motor 12. The clamping shaft 14 is installed on the output end of the second reducer 13, and the first gear 15 and the second gear 16 are arranged on the outer side of the clamping shaft 14, with the first gear 15 located above the second gear 16. The outer sliding seat 20 is located at the lower end of the support 28. The copper wire pressing and chamfering mechanism also includes a double-row cylindrical roller bearing 22, a first cylindrical roller bearing 23, a second cylindrical roller bearing 24, an angular contact ball bearing 25, a transmission seat 34, and a transmission... The second moving seat 35, and the double-row cylindrical roller bearing 22 are rotatably mounted on the support 28 near the end of the reducer 2 13. The first cylindrical roller bearing 23 is mounted on the upper end of the support 28. The second cylindrical roller bearing 24 is mounted on the outer side of the end of the support 28 away from the second gear 16. The first angular contact ball bearing 25 is rotatably mounted on the outer side of the end of the support 28 near the second gear 16. The first transmission seat 34 and the third shaft pin 32 are respectively located on the outer side of the second shaft pin 31 and the third shaft pin 32 inside the support 28. The transverse motor 12 drives the eccentric pressing shaft 14 to rotate, which is transmitted to the second gear 16 and the driven shaft 17 in sequence. The eccentric driven shaft 17 rotates, so that the outer sliding seat 20 connected to the lower pressure seat 11 reciprocates up and down in the guide groove of the support 28.

[0031] When using this cutting composite device with shaping function, the rotational motion of the clamping shaft 14 is transmitted to gear 15 and gear 16. Through the meshing transmission of the gear set, the power is transmitted to the driven shaft 17. The design of the double-row cylindrical roller bearing 22, cylindrical roller bearing 23, cylindrical roller bearing 24, and angular contact ball bearing 25 effectively reduces frictional loss between components and improves the overall service life of the device. In addition, the transmission seats 34 and 35 cooperate with the shaft pins 31 and 32 respectively, ensuring the stability of the mechanism's operation and enabling the copper wire to be precisely clamped and beveled.

[0032] Example 3: Based on the above examples, such as... Figure 1 - Figure 7 The process of the device operating stably is shown in the figure.

[0033] The support 28 is internally provided with driven shaft 17, driven shaft 28 and gear 3 19. Driven shaft 17 is located at the lower end of driven shaft 28 and gear 3 19 is located at the lower end of driven shaft 28. The support 28 is internally provided with angular contact ball bearing 26, cylindrical roller bearing 3 27 and inner sliding seat 21. Angular contact ball bearing 26 and cylindrical roller bearing 3 27 are located on the upper and lower sides of driven shaft 28 respectively, and inner sliding seat 21 is located at the lower end of transmission seat 2 35. The eccentric driven shaft 28 rotates, thereby causing inner sliding seat 21, which is connected to upper pressure seat 10, to reciprocate up and down in the guide groove of outer sliding seat 20.

[0034] When using this cutting composite device with shaping function, the eccentric rotation of driven shaft 28 is transmitted to inner sliding seat 21 through gear 3 19, enabling it to achieve precise up-and-down reciprocating motion within the guide groove. This design ensures coordinated operation between upper and lower pressure seats 10 and 11, thereby applying uniform pressure during the copper wire shaping process. The combination of angular contact ball bearing 26 and cylindrical roller bearing 3 27 effectively reduces frictional loss of driven shaft 2 during high-speed operation, while improving the rigidity and stability of the overall structure. The nested design of inner sliding seat 21 and outer sliding seat 20 further enhances the space utilization of the device, making the entire mechanism more compact and efficient. In actual operation, this precision transmission system can significantly improve the quality of chamfering and shaping, and ensure the accuracy of cutting action, thereby meeting the requirements of high-precision production and increasing the overall practicality.

[0036] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
