Description

Technical Field

[0001] This utility model relates to the field of grooving machine technology, specifically a grooving machine for processing stator and rotor laminations. Background Technology

[0002] In the grooving process of stator and rotor laminations, traditional techniques often employ an integrated punching structure, which involves punching the entire surface of the stator and rotor laminations using a single punching tool. This structure typically includes a separate punching head that performs a one-time punching operation on the surface of the stator and rotor laminations.

[0003] However, traditional one-piece punching methods have some obvious drawbacks. First, because the punching torque is relatively concentrated, it may lead to incomplete punching, especially on thicker or harder stator and rotor materials. When the punching torque is insufficient, the intended groove shape cannot be completed, affecting the processing effect. On the other hand, when the punching torque is too large, it can cause deformation of the stator and rotor, resulting in irregular grooves, which will affect subsequent processing or use.

[0004] Furthermore, in traditional solutions, the distribution of the punching heads is usually quite simple, failing to consider the need for uniform application of punching pressure. This often results in excessive punching force in some areas and insufficient punching force in other areas, ultimately affecting the stability and processing quality of the entire grooving process.

[0005] In view of this, we have studied and improved the existing problems and provided a grooving machine for processing stator and rotor laminations to solve the current problems. The aim of this technology is to solve the problems and improve the practical value. Utility Model Content

[0006] This utility model relates to a grooving machine for processing stator and rotor laminations, specifically a structural design that can accurately punch multiple grooves on the surface of rotor laminations. It mainly solves the problems of incomplete punching, uneven punching force, and large equipment wear in the existing integrated punching structure.

[0007] To achieve the above objectives, this utility model provides a grooving machine for processing stator and rotor laminations, characterized in that it includes a grooving frame, a punching drive assembly, a punch plate, and a plurality of punching heads movably mounted on the surface of the punch plate, wherein:

[0008] The grooving frame has a support plate fixedly installed on one side, and a lifting seat is slidably fitted onto its surface. A drive motor is fixedly installed on the surface of the lifting seat. The lifting seat's downward movement is controlled by the drive motor.

[0009] Punching drive assembly: Fixedly installed on the bottom surface of the lifting base and located directly above the bearing plate, the punching drive assembly includes a fixed cylinder, a shaft, a swashplate seat, a guide sleeve, and several column heads movably fitted inside the guide sleeve. The number of column heads is the same as the number of punching heads, and they are arranged in a one-to-one correspondence. The top end of the fixed cylinder is fixedly connected to the bottom surface of the lifting base, and the output end of the drive motor is connected to the top end of the shaft for driving the rotation of the shaft and the swashplate seat.

[0010] Punch plate: It can be detachably fixed to the bottom surface of the guide sleeve, and the punch plate is magnetically fixed, which makes it easy to disassemble and replace to adapt to different punching requirements. Several punch heads are slidably sleeved on the surface of the punch plate and penetrate through the punch plate.

[0011] The column head and punching head mating structure: The column head and punching head are precisely connected and slidably fitted to ensure that each punching head applies pressure evenly during the punching process, punching the stator and rotor pieces to be punched one by one. The bottom of the punching head is equipped with a cutting blade, the shape of which is consistent with the punching groove contour, which can accurately complete the punching of multi-line grooves.

[0012] Spring pressure column and positioning function: A spring pressure column is fixedly installed inside the guide sleeve. The spring pressure column is perpendicular to the bearing plate surface and is used to position the stator and rotor plates to be punched, ensuring that the stator and rotor plates will not shift during the punching process.

[0013] Optimized structure of the swashplate seat: The bottom surface of the swashplate seat is sloping and has a sliding groove. A ball head sleeve is installed inside the sliding groove. When the swashplate seat rotates, the ball head sleeve pulls the column head, causing it to slide back and forth inside the guide sleeve. The column head, in conjunction with the punching head, punches the surfaces of the stator and rotor plates one by one.

[0014] In practical applications, this utility model's slotting machine for stator and rotor lamination processing can precisely cut the surface of stator and rotor laminations one by one through multiple columns and cutting heads. This effectively avoids the problems of uneven cutting torque and stator / rotor lamination deformation that may exist in traditional one-piece cutting, thus improving the accuracy and stability of slotting processing. Furthermore, the cutting heads are evenly distributed and can be replaced and adjusted using a magnetic fixing method, greatly improving the equipment's efficiency and lifespan.

[0015] The beneficial effects achieved by this utility model are as follows:

[0016] 1. In this utility model, by employing multiple column heads and punching heads to punch the multi-groove structure on the rotor lamination surface one by one, the problems of insufficient punching torque leading to incomplete punching or excessive punching torque leading to deformation of the stator and rotor laminations that may occur in the traditional one-piece punching process are avoided, thus improving the accuracy and stability of the punching process.

[0017] 2. In this utility model, by uniformly distributing and correspondingly arranging the column head and punching head in a circumferential direction, it is ensured that each punching head applies pressure evenly to the surface of the stator and rotor plates to be punched, which effectively improves processing efficiency and reduces the phenomenon of excessive local load during the punching process, thereby extending the service life of the equipment.

[0024] 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 noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0026] The following is in conjunction with the appendix Figures 1-4 This invention describes a grooving machine for processing stator and rotor laminations, based on some embodiments of the present invention.

[0027] The slotting machine for processing stator and rotor laminations of this utility model can be adjusted and optimized according to specific application requirements. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. These embodiments are merely examples and are not intended to limit the scope of this utility model.

[0028] Example 1: Grooving of stator and rotor laminations

[0029] Equipment structure overview:

[0030] The grooving machine of this utility model mainly includes a grooving frame 100, a punching drive assembly 200, and a punching plate 300. The grooving frame 100 provides support, and the punching drive assembly 200 moves up and down by controlling the lifting seat 110, driving multiple column heads 250 and punching heads 310 within the punching drive assembly 200 to perform grooving processing on the stator and rotor plates. A drive motor 120 drives the motor, controlling the rotation of the shaft 220 and the swashplate 230 to achieve precise grooving operation.

[0031] Stator and rotor lamination placement and positioning:

[0032] The stator and rotor plates to be slotted are placed on the surface of the bearing plate 130, and the stator and rotor plates are positioned by the spring pressure column 260 to ensure that the stator and rotor plates will not shift during the slotting process. At this time, the stator and rotor plates are pressed and fixed on the bearing plate 130 to ensure the accuracy of the slotting process.

[0033] Slotting process:

[0034] The lifting seat 110 is controlled to move downward by the operating lever, causing the drive motor 120 to rotate the swashplate seat 230. Because the bottom surface of the swashplate seat 230 is inclined, its inclined surface causes the traction column head 250 to reciprocate within the guide sleeve 240 during rotation. A precise fit is formed between the column head 250 and the punching head 310, ensuring that each punching head 310 applies pressure evenly to the surface of the stator and rotor plates for individual punching. During the punching process, the cutting edge at the bottom of the punching head 310 contacts the surface of the stator and rotor plates, completing the punching of multiple grooves according to the set contour.

[0035] One-by-one punching of multi-channel grooves:

[0036] During the blanking process, multiple column heads 250 and blanking heads 310 are evenly distributed in the circumferential direction. Each blanking head 310 completes the blanking task one by one, avoiding the situation of incomplete or excessive blanking that may occur in traditional one-piece blanking structures. This one-by-one blanking method ensures the accuracy of the blanking depth and shape, and avoids the phenomenon of deformation or uneven blanking on the surface of the stator and rotor plates.

[0037] Slotting completed and stator / rotor laminations removed:

[0038] After the grooving is completed, the lifting seat 110 is raised by controlling the operating lever to remove the stator and rotor blades from the bearing plate 130. After each grooving is completed, the next stator and rotor blade can be processed. Due to the design structure of this utility model, the entire grooving process requires no manual intervention, has a high degree of automation, and can improve production efficiency.

[0039] Equipment disassembly and maintenance:

[0040] The punch plate 300 of this invention is magnetically fixed to the bottom surface of the guide sleeve 240, facilitating disassembly and replacement to adapt to different punching requirements. Each time the punching tool is changed, the punch plate 300 and the punching head 310 can be quickly disassembled via magnetic attachment, saving time on equipment maintenance and tool replacement, and improving the flexibility of equipment use.

[0041] Example 2: Adjustment and Optimization

[0042] Adaptable to grooving of different stator and rotor laminations:

[0043] The structure of this utility model can be modified to use different shaped cutting blades according to different thicknesses, materials or grooving requirements, ensuring efficient and accurate grooving under various conditions.

[0044] Equipment automation improvements:

[0045] This invention can be equipped with automated devices, such as conveyor belts and automatic positioning systems, as needed to achieve more efficient stator and rotor lamination grooving in mass production.

[0046] Summarize

[0047] This embodiment, through the detailed structural design and processing flow described above, solves the problems of unevenness and deformation in the stator and rotor lamination slotting process of the existing integrated punching structure, thereby improving processing accuracy and stability. Simultaneously, the magnetic fixing design makes the equipment more flexible and maintainable, suitable for processing various stator and rotor laminations, and effectively improves production efficiency.

[0048] Working principle and usage process of this utility model:

[0049] The stator and rotor plates to be punched are placed on the surface of the bearing plate 130. The downward movement of the lifting seat 110 drives the punching drive assembly 200 and the punching plate 300 downwards, causing the spring pressure column 260 to first contact the surface of the stator and rotor plates to be punched, and then until the bottom surface of the punching head 310 contacts the surface of the stator and rotor plates to be punched, pressing and fixing the stator and rotor plates to be punched to prevent displacement within the punching groove. Driven by the drive motor 120, the shaft 220 and the swashplate seat 230 rotate. During the rotation of the swashplate seat 230... By utilizing the inclined surface of its bottom, the ball head sleeve 231 pulls the column head 250 to reciprocate within the guide sleeve 240 during rotation, causing the guide sleeve 240 to impact the punching head 310 on the surface of the punching plate 300 during the stroke. The punching head 310 cuts grooves on the surface of the stator and rotor plates to be punched. After one revolution of the inclined plate seat 230, each punching head 310 punches grooves one by one. After the grooving is completed, the lifting seat 110 moves upward to remove the stator and rotor plates on the surface of the bearing plate 130, and repeats the operation for the next stator and rotor plates to be punched.
