Description

Technical Field

[0001] This utility model relates to the field of motor core manufacturing technology, specifically to an anti-deviation motor core stacking mechanism. Background Technology

[0002] The motor core is a key component in an electric motor responsible for transmitting the magnetic field. It is typically made of laminated silicon steel sheets. Its main function is to enhance the magnetic field generated by the current, thereby achieving efficient conversion between electrical energy and mechanical energy. The quality and performance of the motor core directly affect the efficiency and lifespan of the motor, thus playing a crucial role in motor design and manufacturing.

[0003] According to CN216027413U, a tooling for manufacturing laminated motor cores is described. During use, the maximum pressure value of a pressure sensor is set via an external terminal. When the pressure exceeds the set value, the upper punch stops pressing down to avoid damaging the mold. The upper mold base is connected to the drive mechanism of the stamping machine, controlling the upper mold base to move downwards. When the upper punch moves down to a certain height, if the pressure sensor does not detect pressure, it indicates that the positions of the upper punch and lower die have shifted, requiring realignment to avoid stamping during this shift. If the pressure sensor detects pressure, it indicates that the receiving column is in contact with the positioning rod, and the positions of the upper punch and lower die have not shifted, allowing continued pressing. The spring force of the first spring provides buffering to prevent excessive pressure during stamping from damaging the mold. This tooling is convenient to use and has good performance.

[0004] The above-mentioned first spring and other structures can achieve the buffering of the mold. However, when the motor core is stacked, since the motor core is made by stacking multiple pieces and pressing them, the pieces are placed in the cavity without limiting, which can easily cause the pieces to shift and result in misalignment of the stacked motor core.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1 to 5 As shown, in this embodiment, an anti-deviation motor core stacking mechanism includes a support platform 1. A lower mold 2 is fixedly connected to the top of the support platform 1. Four guide grooves 3 are evenly distributed circumferentially on the bottom of the inner wall of the lower mold 2. A cylinder 4 is fixedly connected to the bottom of the support platform 1. The output rod of the cylinder 4 passes through the support platform 1 and the lower mold 2 and is fixedly connected to a mounting column 5 at one end. Four sets of rotating seats 6 are evenly distributed circumferentially on the surface of the mounting column 5. A rotating plate 7 is rotatably connected inside the rotating seat 6. A rotating seat 8 is rotatably connected to the side of the rotating plate 7 away from the rotating seat 6. A positioning plate 9 is fixedly connected to the side of the rotating seat 8 away from the rotating plate 7. A guide block 10 is fixedly connected to the bottom of the positioning plate 9. The guide block 10 is located inside the guide groove 3.

[0024] A suitable amount of iron core laminations are placed in the lower mold 2 in a certain order, and the four positioning plates 9 are positioned in the positioning holes at the center of the laminations. The cylinder 4 is activated, and its output rod pulls the mounting column 5 downward. The rotating plate 7 rotates between the rotating base 6 and the rotating base 8, and pushes the positioning plates 9 closer to the laminations. The guide groove 3 and the guide block 10 both adopt a T-shaped structure, so that the guide groove 3 limits the guide block 10 while the guide block 10 slides inside the guide groove 3. After moving a certain distance, the positioning plate 9 contacts the inner wall of the positioning hole at the center of the lamination, thereby restricting the movement of the laminations and ensuring the stability of the iron core during stacking.

[0025] When in use, the height of the positioning plate 9 is set according to the needs of the motor core, so as to avoid the positioning plate 9 interfering with the movement of the upper mold 19 when the lower mold 2 and the upper mold 19 are closed, thus affecting the normal stacking of the core laminations.

[0026] A sliding rod 12 is slidably connected to the top of the mounting column 5, and a connecting spring 11 is fixedly connected between the sliding rod 12 and the inner wall of the mounting column 5.

[0027] When the mounting plate 17 moves the upper mold 19 downward, the upper mold 19 and the slide rod 12 come into contact, the connecting spring 11 is squeezed and contracted, and the movement of the upper mold 19 is slowed down by the elastic force of the connecting spring 11, so as to avoid excessive mechanical pressure during the application of pressure and damage to the iron core laminations.

[0028] The top of the support platform 1 is fixedly connected to four pillars 13, the top of the pillars 13 is fixedly connected to a top plate 14, and the top of the top plate 14 is fixedly connected to a cylinder 15.

[0029] Two guide pillars 16 are symmetrically arranged between the top plate 14 and the lower mold 2. The surface of the guide pillars 16 is slidably connected to the mounting plate 17, and the mounting plate 17 is fixedly connected to the output rod of the cylinder 15.

[0030] The mounting plate 17 has symmetrical guide holes 18 on both sides, the guide holes 18 are compatible with the guide posts 16, and the bottom of the mounting plate 17 is fixedly connected to the upper mold 19.

[0031] When cylinder 15 is activated, its output rod pushes the mounting plate 17 and the upper mold 19 downward. The mounting plate 17 slides on the surface of the guide post 16. Through the matching of the guide post 16 and the guide hole 18, the accuracy of the upper mold 19 and the lower mold 2 when they are closed is ensured, and misalignment is avoided.

[0032] The bottom of the support platform 1 is symmetrically provided with connecting frames 20 on both sides. The top of the connecting frame 20 is fixedly connected to a drive motor 21. The output shaft of the drive motor 21 is fixedly connected to a connecting shaft 22. The surface of the connecting shaft 22 is fixedly fitted with a convex rib plate 23.

[0033] The bottom of the lower mold 2 and the support platform 1 are slidably connected to the ejector pin 24. The bottom of the ejector pin 24 is fixedly connected to the pad 25. A return spring 26 is provided between the pad 25 and the support platform 1. The return spring 26 is movably sleeved on the outside of the ejector pin 24.

[0034] Start the drive motor 21, and its output shaft drives the connecting shaft 22 to rotate. The convex plate 23 rotates accordingly. After rotating to a certain angle, the convex plate 23 contacts the pad 25 and pushes it upward. The return spring 26 is squeezed and contracted, and the ejector pin 24 rises accordingly, thereby pushing the stacked iron core out of the lower mold 2 for easy material removal.

[0035] This utility model provides an anti-deviation motor core stacking mechanism, the specific working principle of which is as follows:

[0036] In use, place an appropriate amount of iron core laminations in the lower mold 2 in a certain order, and position the four positioning plates 9 in the positioning holes at the center of the laminations. Start cylinder 4, whose output rod pulls the mounting column 5 downwards. The rotating plate 7 rotates between rotating base 6 and rotating base 8, pushing the positioning plates 9 closer to the laminations. The guide groove 3 limits the guide block 10 and causes it to slide inside the guide groove 3. After moving a certain distance, the positioning plate 9 contacts the inner wall of the positioning hole at the center of the laminations, preventing movement between adjacent laminations. Start cylinder 15, whose output rod pushes the mounting plate 17 and the upper mold 19 downwards. The mounting plate 17 slides on the surface of the guide column 16. After moving a certain height, the upper mold 19 contacts the sliding rod 12. The mounting plate 17 continues to move downwards, compressing and contracting the connecting spring 11. Rod 12 slides inside mounting column 5, upper mold 19 contacts the topmost stacked pieces and applies pressure to the stacked pieces. Pressure sensors are installed on both upper mold 19 and lower mold 2 to monitor the pressure in real time and make fine adjustments to the position of upper mold 19 as needed. After the position is appropriate, the pressure is maintained for a period of time to firmly press the iron core stacked pieces together to form a whole motor iron core. After pressing, cylinder 2 15 drives upper mold 19 to move upward, cylinder 1 4 separates positioning plate 9 from stacked pieces. At this time, drive motor 21 is started, and its output shaft drives connecting shaft 22 to rotate. The convex rib plate 23 rotates accordingly. After rotating to a certain angle, the convex rib plate 23 contacts pad plate 25 and pushes it upward. Ejector pin 24 rises accordingly, thereby pushing the stacked iron core out of lower mold 2.

[0037] 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.
