Description

Technical Field

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

[0002] The stator and rotor laminations of an electric motor are one of the core components of the motor. They are usually made of silicon steel sheets through a stamping process and are widely used in various electric motors, generators and servo motors. The quality of the laminations directly affects the performance and efficiency of the motor. During the processing, silicon steel coils need to be continuously stamped into laminations with specific grooves and contours through stamping equipment, and a fixing device is used to ensure stamping accuracy and stability in order to meet the needs of efficient and mass production.

[0003] A search revealed a high-speed grooving machine for processing stator and rotor laminations, patent publication number "CN 221537803 U". The machine includes a base, with a mounting seat fixedly connected to the center of the top of the base. A threaded groove is provided at the center of the top of the mounting seat, and a fastener is threadedly connected to the threaded groove. A limiting component is threadedly connected to the fastener. A mounting groove is provided through the top of the mounting seat near the side wall, and a mounting plate is fitted to the mounting groove. A processing groove is provided through the top of the mounting plate. This invention features a fastener and a limiting component threadedly connected to the center of the top of the mounting seat. The limiting component is used to install and limit the movement of the stator and rotor, and it is easy to disassemble and replace. The mounting plate facilitates adjustment of the processing position, thus enabling the processing of different stator and rotor models and increasing the applicability of the device.

[0004] The above technical features have the following shortcomings: In this solution, the limiting component and the fastener are connected by a threaded connection, and the rotor lamination is fixed by the limiting component. Although the limiting component is described as "easy to disassemble and replace", in actual operation, the threaded connection still requires tools to rotate and disassemble, which is cumbersome and inefficient. Secondly, when the mounting plate needs to process laminations of different specifications, it needs to be removed from the mounting base for replacement, which is also troublesome and affects the actual processing efficiency.

[0005] Therefore, a high-speed slotting machine for stator and rotor lamination processing is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a high-speed grooving machine for processing stator and rotor laminations, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-speed grooving machine for processing stator and rotor laminations, comprising a stamping table and a stamping die table inserted on top of the stamping table, and laminations disposed on the top of the stamping die table. Multiple matching pressure blocks are arranged circumferentially near the inner wall of the laminations. Each pressure block has a limiting block below it, and the limiting blocks are inserted into the interior of the stamping die table. A movable block is threaded to one side of each pressure block. A reset mechanism is provided on one side corresponding to a set of movable blocks and limiting blocks. The reset mechanism controls the pressure blocks to press the laminations onto the top of the stamping die table, facilitating actual processing and allowing for replacement of the stamping die table as needed.

[0008] Preferably, the plurality of limiting blocks are fixedly connected to the corresponding movable blocks, and the inner sidewall of the stamping die table is provided with a plurality of limiting grooves, and the plurality of limiting blocks are respectively inserted into the interior of the corresponding limiting grooves.

[0009] Preferably, the reset mechanism includes limiting springs fixedly connected to one side of the corresponding movable block, and multiple limiting springs are fixedly connected to the stamping table. The inner sides of the multiple movable blocks are provided with matching cam blocks, and the cam blocks are internally connected to drive shafts.

[0010] Preferably, the bottom of the stamping table is provided with a plurality of sliding grooves in the circumferential direction, the other ends of the plurality of limiting springs are respectively fixedly connected to the inside of the corresponding sliding groove, and the plurality of movable blocks are respectively slidably connected to the inside of the corresponding sliding groove.

[0012] Preferably, the stamping table has a blanking groove inside, and the stamping die table has a stamping groove inside that matches the blanking groove for continuous stamping of materials.

[0013] Preferably, the bottom of the stamping table is connected to a drive wheel for driving the stamping table to rotate, and the outer wall of the cam block is a curved surface with concave and convex shapes.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model achieves rapid pressing and releasing of the punch by setting a pressure block, a movable block, a limit block and a reset mechanism. Specifically, the pressure block and the movable block are threaded together, which facilitates the quick replacement of the pressure block according to the different specifications of the punch. The reset mechanism, through the cooperation of the cam block and the limit spring, can control the pressing and releasing of the punch by the pressure block, avoiding the cumbersome operation of repeated rotation and disassembly with tools required by the traditional threaded connection method.

[0016] 2. In addition, the stamping die table and the stamping table are connected by a plug-in method, and the positioning is achieved by the cooperation of the limit block and the limit groove, which facilitates the quick replacement of the die table. When it is necessary to replace the die table of different specifications, simply rotate the cam block to release the limit, and the limit spring will push the movable block to drive the limit block to disengage from the limit groove, thereby quickly removing the die table. This structure simplifies the die replacement process, reduces downtime, improves the equipment's adaptability to different types of stamping pieces, and enhances the overall processing efficiency and equipment versatility.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Example 1: Please refer to Figures 1-3 This utility model provides a technical solution: a high-speed grooving machine for processing stator and rotor laminations, including a stamping table 1 and a stamping die table 2 inserted on top of it, and laminations 3 set on the top of the stamping die table 2. Multiple matching pressure blocks 4 are arranged circumferentially near the inner wall of the top of the laminations 3. Each pressure block 4 is provided with a limiting block 9 below it. The multiple limiting blocks 9 are inserted into the interior of the stamping die table 2. Each side of the multiple pressure blocks 4 is threaded with a movable block 5. Through the threaded connection, it is convenient to replace the pressure blocks 4 of different specifications according to the actual processing situation to press the laminations 3. A reset mechanism is provided on one side of a set of movable blocks 5 and limiting blocks 9. The reset mechanism controls the pressure blocks 4 to press the laminations 3 on the top of the stamping die table 2, which is convenient for actual processing. At the same time, the stamping die table 2 can be replaced as needed.

[0023] The bottom of each of the multiple pressure blocks 4 is equipped with a wear-resistant pad, and the multiple wear-resistant pads are all made of rubber material.

[0024] In this embodiment, multiple limiting blocks 9 are fixedly connected to the corresponding movable blocks 5. Multiple limiting grooves 10 are distributed circumferentially on the inner sidewall of the stamping die table 2. Multiple limiting blocks 9 are inserted into the interior of the corresponding limiting grooves 10. The limiting grooves 10 are used to control the horizontal movement of the limiting blocks 9 to prevent deviation.

[0025] In this embodiment, the reset mechanism includes limiting springs 6 fixedly connected to one side of the corresponding movable block 5. Multiple limiting springs 6 are fixedly connected to the stamping table 1. Matching cam blocks 7 are provided on the inner sides of the multiple movable blocks 5. A drive shaft 8 is connected inside the cam block 7. A drive wheel 14 is connected to the bottom of the stamping table 1. The drive wheel 14 is typically driven by an external motor connected to a gear, causing the fixed stamping sheet 3 to rotate, thus achieving continuous stamping operation. It is used to drive the stamping table 1 to rotate. The outer wall of the cam block 7 is a curved surface with concave and convex features. Specifically, after rotating the cam block 7 in the reset mechanism and releasing the limit on the movable block 5, the movable block 5 and the connected limit block 9 are pushed to one side under the action of the limit spring 6. When the pressure block is first separated from the surface of the (4) punch 3, the material can be moved up and down. Then, under the further action of the limit spring 6, the limit block 9 is pushed away from the stamping die table 2, and the limit on it is released. At this time, the stamping die table 2 can be taken out from the top of the stamping table 1 and replaced with a stamping die table 2 of the corresponding specification for processing.

[0026] The bottom of the stamping table 1 is provided with multiple sliding grooves 11. The other ends of multiple limit springs 6 are fixedly connected to the inside of the corresponding sliding grooves 11. Multiple movable blocks 5 are slidably connected to the inside of the corresponding sliding grooves 11 to ensure that the movable blocks 5 slide horizontally inside the sliding grooves 11.

[0027] In this embodiment, the stamping table 1 is provided with a material discharge groove 13 inside, and the stamping die table 2 is provided with a stamping groove 12 that matches the material discharge groove 13 inside, for continuous material stamping. The stamping sheet 3 is continuously stamped through the stamping groove 12 inside the stamping die table 2, and the excess material generated is discharged through the material discharge groove 13.

[0028] The working principle is as follows: In actual processing, the blank 3 to be processed is first placed on the top of the stamping die table 2, and multiple matching pressure blocks 4 are arranged circumferentially near the inner side wall of the blank 3. A limiting block 9 is provided below the pressure block 4, and the limiting block 9 is inserted into the limiting groove 10 inside the stamping die table 2. A movable block 5 is threadedly connected to one side of the pressure block 4. The movable block 5 and the limiting block 9 are provided with a reset mechanism. The reset mechanism includes a limiting spring 6 and a cam block 7. The limiting spring 6 is fixedly connected to the movable block 4. One side of block 5 is fixedly connected to the stamping table 1. The drive shaft 8 is connected inside the cam block 7. The drive shaft 8 is usually externally connected to a drive device, such as a motor. The outer wall of the cam block 7 is a curved surface with concave and convex features. When the drive shaft 8 drives the cam block 7 to rotate, the curved surface of the cam block 7 contacts the inner side of the movable block 5, pushing the movable block 5 to slide outward along the slide groove 11, compressing the limit spring 6, and at the same time driving the pressure block 4 and the limit block 9 to move outward, releasing the pressure and limit on the punch 3. At this time, the punch 3 or the stamping die can be replaced. When the cam block 7 continues to rotate and its curved surface disengages from the inner side of the movable block 5, the limiting spring 6 resets, pushing the movable block 5 to slide inward along the slide groove 11, causing the pressure block 4 and the limiting block 9 to move inward. The pressure block 4 presses the punch 3 against the top of the stamping die table 2, and the limiting block 9 is inserted into the limiting groove 10 to limit and fix the punch 3. The bottom of the stamping table 1 is connected to a drive wheel 14 for driving the stamping table 1 to rotate. The inside of the stamping table 1 is provided with a blanking groove 13, and the inside of the stamping die table 2 is... A stamping groove 12 matching the discharge groove 13 is provided for continuous material stamping. The stamping plate 3 is continuously stamped through the stamping groove 12 inside the stamping die table 2, and the excess material is discharged through the discharge groove 13. The bottom of the pressure block 4 is provided with a wear-resistant pad made of rubber material, which improves the service life and pressing effect of the pressure block 4. This utility model realizes the rapid pressing and releasing of the stamping plate 3 through the above structure, which facilitates the replacement of the stamping plate 3 and the stamping die table 2, and improves the processing efficiency and equipment versatility.

[0029] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
