Description

Technical Field

[0001] This invention relates to the field of mechanical equipment, and more particularly to a magnetic steel pressing device. Background Technology

[0002] With social progress and development, China's use of magnets has surpassed the world average. When assembling motor rotors, magnet assembly is a crucial step. In the past, it was entirely done manually. First, the magnets had to be separated into individual pieces, then glued, and then workers would insert them one by one into the rotor core. Because the magnets are extremely strong, manual operation was not only labor-intensive but also dangerous. Slight negligence could cause the polarity to be reversed, affecting the assembly quality. Furthermore, manual insertion of magnets was inefficient and the workload of assembly personnel was heavy.

[0003] Currently, in the production of some motors, robotic arms are used to insert magnets into the rotor core. However, due to the high positioning accuracy required during the insertion process, magnets may fail to be inserted, affecting assembly quality. Furthermore, the limited number of robotic arms prevents the simultaneous insertion of multiple magnets, impacting work efficiency.

[0004] Therefore, there is a need for a magnetostatic device that can simultaneously insert multiple magnets and achieve precise positioning. Summary of the Invention

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0027] See Figure 1-4This invention provides a magnet pressing device, including a frame 1, a loading platform on the frame 1, a guide plate 2 above the loading platform, a pressing mechanism 3 above the guide plate 2, and a plurality of pushing mechanisms 4 on the guide plate 2. The guide plate 2 has a plurality of pressing ports 21 corresponding to the number of pushing mechanisms 4. The pressing ports 21 are the same size as the magnets. The pressing mechanism 3 simultaneously presses a plurality of magnets through the pressing ports 21 into the iron core on the loading platform. The pushing mechanism 4 includes a hopper 41 on the guide plate 2, a pushing assembly, and a baffle 42 located at the edge of the pressing port 21 away from the hopper 41. The pushing assembly pushes the magnets in the hopper 41 towards the baffle 42. The magnet is positioned above the pressing port 21. A blocking component is provided above the pressing port 21 to restrict the magnet from falling. The pushing mechanism 4 is equipped with a sensor 7 to monitor the number of times the magnet is loaded. Preferably, there are 8 pushing mechanisms 4 and 8 pressing ports 21. This invention feeds materials simultaneously through 8 pushing mechanisms, and the pressing mechanism 3 can insert 8 magnets into the iron core at the same time, improving work efficiency. Through the cooperation of the guide plate 2, the pressing port 21, the baffle 42 and the blocking component, the magnet can be accurately positioned between the iron core and the pressing mechanism 3, which makes it convenient for the pressing mechanism 3 to accurately press the magnet into the iron core, improving the overall automation level, effectively reducing manpower and improving assembly quality.

[0028] Preferably, the pushing assembly includes a pushing cylinder 43 disposed on the frame 1 and a push rod 44 disposed at the movable end of the pushing cylinder 43, the push rod 44 pushing the magnet out of the hopper 41.

[0029] Preferably, the blocking assembly includes a fixed block on the frame 1, a push block 52 above the pressing port 21, and a spring connecting the fixed block and the push block 52. The push block 52 is provided with an inclined surface 54 that drives the push block 52 to move towards the fixed block. The push rod 44 pushes the magnet towards the baffle 42. The magnet is horizontally fixed by the push rod 44 and the baffle 42. At this time, the magnet falls on the inclined surface 54 of the push block 52. Through the elastic force of the spring on the push block 52, the inclined surface 54 supports the magnet and prevents the magnet from falling into the pressing port 21 below. At this time, the magnet is in a balanced state under the action of the push rod 44, the push block 52 and the baffle 42, waiting for the pressing mechanism 3 above to press down. After being subjected to pressure, the push block 52 moves away from the pressing port 21. When the pressure is released, the push block returns to above the pressing port 21, which has an automatic reset function. The angle between the inclined surface 54 and the horizontal plane is 45-75°, preferably 50°, 60° or 70°.

[0030] Preferably, the pressing mechanism 3 includes a pressing cylinder mounting plate 31 mounted on the frame 1, a pressing cylinder 32 mounted on the pressing cylinder mounting plate 31, and a pressing plate 33 mounted on the movable end of the pressing cylinder 32. The pressing plate 33 drives the magnet to pass through the pressing port 21. The pressing plate 33 is provided with a plurality of pressing blocks 34, and the positions of the pressing blocks 34 correspond one-to-one with the pressing ports 21. The plurality of pressing blocks 34 press down at the same time, pressing the corresponding magnets below through the pressing ports 21 and into the iron core, effectively reducing the need for the same work process and mechanical actions, and improving work efficiency.

[0031] Preferably, a plurality of guide rods 35 are provided between the frame 1 and the pressure cylinder mounting plate 31, and the pressure plate 33 is provided with guide through holes that cooperate with the guide rods 35. The guide rods 35 cooperate with the guide through holes to guide the pressure plate 33, which can prevent the pressure plate 33 from shifting due to loosening between the components of the pressure mechanism 3. This would result in uneven force on the magnets below, and some magnets would not be able to pass through the pressure port 21 smoothly due to the small force. Alternatively, the force on the magnets may change from a single vertical downward force to a resultant force of both a vertical downward force and a horizontal force, causing the magnets to break the original balance in the horizontal direction and shift, resulting in misalignment between the magnets and the pressure port 21 and preventing them from passing through the pressure port 21 smoothly.

[0032] Preferably, the frame 1 is equipped with several lifting cylinders 61 and several guide columns 62, which can adjust the overall height according to different work needs, adapt to different work occasions and different work environments, and improve overall adaptability.

[0033] During operation, the overall height is first adjusted using the lifting cylinder 61 according to work requirements. The operator places the iron core on the loading platform, aligns the magnet slots with the pressing ports 21, and places magnets in the corresponding hoppers 41 according to the iron core structure and requirements. The pushing cylinder 43 extends, driving the push rod 44 to push the magnets in the hoppers 41 towards the baffle 42. The push rod 44, baffle 42, and push block 52 position the magnets above the pressing ports 21. The pressing cylinder 32 extends, driving... The pressure plate 33 and pressure block 34 move downward and apply vertical downward pressure to the magnet. The magnet applies a pushing force to the inclined surface 54 on the push block 52, thereby compressing the spring and driving the push block 52 to move in the direction of the spring. When the push block 52 is pushed away from the top of the pressure port 21, the magnet passes through the pressure port 21 under the action of pressure and inserts into the iron core. The pressure cylinder 32 and the push cylinder 43 retract, and the push block 52 returns to its original position under the action of the spring, reaching the top of the pressure port 21.

[0034] In summary, this invention provides a magnet pressing device. Eight feeding mechanisms simultaneously feed the magnets, and the pressing mechanism 3 can simultaneously insert eight magnets into the iron core, improving work efficiency. Through the cooperation of the guide plate 2, pressing port 21, baffle 42, and blocking components, the magnets can be precisely positioned between the iron core and the pressing mechanism 3, facilitating the precise pressing of the magnets into the iron core and improving the overall automation level. This effectively reduces manpower and improves assembly quality. The push block 52, under the action of a spring, can move on the guide plate 2, acting as both a block and a conductor for the pressing port 21, while also providing an automatic reset function. The pressing mechanism 3 is equipped with a guide rod 35, ensuring uniform force on each magnet below and improving operational stability.

[0035] It should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
