Description

Technical Field

[0001] The utility model relates to the technical field of magnetic steel inserting machines, in particular to a magnetic steel pressing mechanism and a magnetic steel inserting machine. Background Technique

[0002] The motor of a new energy vehicle is one of the core components of its power system. It generates a rotating magnetic field through the stator, and the magnetic field of the rotor interacts with it to generate torque, thereby driving the rotor to rotate. Among them, the rotor of a permanent magnet synchronous motor uses permanent magnets to generate a magnetic field. The permanent magnets are usually composed of high-performance magnetic materials, such as rare earth magnets like neodymium iron boron (NdFeB) or samarium cobalt (SmCo). These materials have high magnetization intensity and can generate a relatively high magnetic field intensity to interact with the rotating magnetic field of the stator.

[0003] In the existing magnetic steel inserting technology, usually, a group of magnetic steels are manually sliced, and the permanent magnets are inserted into the positions pre-designed on the rotor with the help of a press. During this process, the stroke and pressure of the press are determined manually. This pressing method makes the path of pressing the magnetic steel into the rotor not fixed, and thus the pressure required for pressing the magnetic steel is not the same. When the magnetic steel is pressed into the rotor obliquely, the press needs a greater pressure to press it into the rotor, and this pressure may exceed the compressive strength of the magnetic steel and damage it. Content of the Utility Model

[0004] In order to solve the problem that the path of pressing the magnetic steel in the existing technology cannot be fixed, the utility model provides a magnetic steel pressing mechanism and a magnetic steel inserting machine. The specific technical solutions are as follows:

An insertion port and a pressing port are formed at the intersection of the feeding table and the long rod. The long rod enters the horizontal cavity from the insertion port and moves away from the horizontal cavity from the pressing port under the drive of the pressing cylinder.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0024] Embodiment 1

[0025] Such as Figure 1As described above, Embodiment 1 of the present utility model includes: a horizontal feeding assembly 11, and the horizontal feeding assembly 11 includes a buffer bin 112; and a vertical pressing assembly 12, and the vertical pressing assembly 12 includes a pressing cylinder 121, and the telescopic path of the pressing cylinder 121 intersects the buffer bin 112 at a feeding table 114, and the telescopic path of the pressing cylinder 121 penetrates through the feeding table 114.

[0026] Specifically, the inside of the buffer bin 112 is used for placing magnetic steel, and the plane where the buffer bin 112 is located is a horizontal plane, so that the magnetic steel can move along the horizontal plane in the buffer bin 112 under mutual extrusion; secondly, the telescopic end of the pressing cylinder 121 is vertically downward, and its telescopic direction is thus vertically downward. The horizontal movement path of the magnetic steel intersects the telescopic path of the telescopic end of the pressing cylinder 121 at the feeding table 114. The inside of the feeding table 114 is communicated with the inside of the buffer bin 112, so that the magnetic steel can enter the feeding table 114 along the buffer layer. Secondly, the pressing cylinder 121 can penetrate through the feeding table 114, so that after the magnetic steel enters the feeding table 114, it can be vertically pressed out of the feeding table 114 by the pressing cylinder 121. Furthermore, the movement path of the magnetic steel is first to move along the buffer bin 112 to the feeding table 114, and then the pressing cylinder 121 presses it out of the feeding table 114, so that the magnetic steel is separated and pressed into the rotor along a fixed path.

[0027] Furthermore, the horizontal feeding assembly 11 further includes: a horizontal cylinder 111 whose telescopic end is arranged at one end of the buffer bin 112, the telescopic direction of the horizontal cylinder 111 is the same as the length direction of the buffer bin 112, and the telescopic path of the horizontal cylinder 111 overlaps with the buffer bin 112; and a feeding table 114 arranged at the other end of the buffer bin 112, and a horizontal cavity 115 is formed in the feeding table 114 along the length direction of the buffer bin 112.

[0028] Specifically, a cavity is formed inside the buffer bin 112, and the telescopic end of the horizontal cylinder 111 makes a telescopic movement in the cavity of the buffer bin 112, thereby pushing the internal magnetic steel therein towards the horizontal cavity 115, so that the movement path of the magnetic steel is limited within the cavity of the buffer bin 112 and the horizontal cavity 115. The axis of the telescopic end of the horizontal cylinder 111, the horizontal center line of the cavity of the buffer bin 112, and the horizontal center line of the horizontal cavity 115 coincide with each other. Furthermore, the magnetic steel is always perpendicular to the axis of the telescopic end of the horizontal cylinder 111 during the movement process, and thus the magnetic steel is perpendicular to it when moving to the horizontal cavity 115. Furthermore, during the process of the pressing cylinder 121 pressing out the magnetic steel, the outer surface of the magnetic steel is always parallel to the movement direction of the pressing cylinder 121, so that the magnetic steel will not be pressed out of the feeding table 114 obliquely, thereby reducing the downward pressure it receives and reducing the risk of it being crushed.

[0029] Further, the vertical press-fitting assembly 12 further includes a long rod 123 disposed at the telescopic end of the press-fitting cylinder 121. The length direction of the long rod 123 is the same as the telescopic direction of the press-fitting cylinder 121. An insertion port 1141 and a press-fitting port 1142 are formed at the intersection of the feeding table 114 and the long rod 123. Driven by the press-fitting cylinder 121, the long rod 123 enters the horizontal cavity 115 from the insertion port 1141 and exits the horizontal cavity 115 from the press-fitting port 1142.

[0030] Specifically, the telescopic end of the press-fitting cylinder 121 presses the magnet through the long rod 123. The long rod 123 can penetrate the feeding table 114. The long rod 123 presses the magnet downward from the insertion port 1141 and presses the magnet out of the horizontal cavity 115 along the direction of the press-fitting port 1142. During this process, the grouped magnets can be separated into individual magnets by the intersection line of the press-fitting port 1142 and the horizontal cavity 115. The individual magnets then enter the press-fitting port 1142 and enter the rotor, which enables the magnets to automatically separate and perform the press-fitting process. It can not only fix the press-fitting path of the magnets, but also improve the press-fitting efficiency of the magnets and reduce the probability of the magnets being crushed.

[0031] Combined with Figure 2 As shown, the horizontal feeding assembly 11 further includes: a two-way opening and closing cylinder 117, the telescopic direction of the two-way opening and closing cylinder 117 is perpendicular to both the length direction of the buffer bin 112 and the length direction of the long rod 123; and an opening and closing bracket 118 disposed at the telescopic end of the two-way opening and closing cylinder 117. The other end of the opening and closing bracket 118 can limit the side of the press-fitting port 1142 away from the horizontal cavity under the drive of the telescopic end of the two-way opening and closing cylinder 117.

[0032] Specifically, the left and right sides of the two-way opening and closing cylinder 117 approach or move away from each other simultaneously. When it approaches, the ends intersecting with the feeding table 114 approach each other, so that the opening and closing bracket 118 can cover the press-fitting port 1142, and thus the magnets in the horizontal cavity 115 cannot pass through the press-fitting port 1142. This process is the preparation for the press-fitting cylinder 121 to press the magnets and the process of the buffer bin 112 replenishing the magnets; when it moves away, the ends intersecting with the feeding table 114 move relatively away from each other, so that the magnets in the horizontal cavity 115 can pass through the press-fitting port 1142. This process is for the press-fitting cylinder 121 to press the magnets onto the rotor, and thus the moving directions of the magnets are limited differently in different processes, which can improve the press-fitting efficiency and quality.

[0033] As Figure 3 and Figure 5As shown, the horizontal feeding assembly 11 further includes: a locking tongue 116 disposed in the horizontal cavity 115. The locking tongue 116 forms a limiting surface, which is perpendicular to the length direction of the buffer bin 112. The limiting surface coincides with the surface of the long rod 123 away from the buffer bin 112. The locking tongue 116 moves telescopically perpendicular to the horizontal cavity 115 and relative to the feeding table 114.

[0034] Specifically, a limiting surface is formed on the side of the locking tongue 116 close to the magnet. This limiting surface can limit the magnet from moving out of the horizontal cavity 115, enabling it to be just within the coverage range of the press-fitting port 1142. Thus, during the process of the press-fitting cylinder 121 press-fitting the magnet, the magnet can just pass through the press-fitting port 1142, preventing the side surface of the magnet from forming an angle with the side surface of the press-fitting port 1142 and increasing the downward pressure on the magnet, thereby avoiding crushing the magnet due to excessive downward pressure. Secondly, during the process of replenishing the magnet in the buffer bin 112, the locking tongue 116 can retract into the feeding table 114 by relying on the spring at the bottom, allowing the external magnet to enter the buffer bin 112 through the horizontal cavity 115 and improving the assembly efficiency of the magnet.

[0035] As Figure 4 shown, the vertical press-fitting assembly 12 further includes a buffer connecting member 122 disposed at the telescopic end of the press-fitting cylinder 121. The buffer connecting member 122 includes: an elastic member 1221 connected to the telescopic end of the press-fitting cylinder 121, and the deformation direction of the elastic member 1221 is the same as the telescopic movement direction of the press-fitting cylinder 121; and a pressure sensor 1224 disposed at the other end of the elastic member 1221. The elastic member 1221 applies a downward pressure to the pressure sensor 1224 when being compressed, and this downward pressure is transmitted to the feeding table 114.

[0036] Specifically, when the telescopic end of the press-fitting cylinder 121 moves downward, the telescopic end squeezes the elastic member 1221. The elastic member 1221 absorbs energy and compresses, which can buffer the downward pressure of the press-fitting cylinder 121, preventing this downward pressure from directly acting on the magnet, filtering the pressure curve of the downward pressure to make it gentle, and thus avoiding damaging the magnet due to sudden changes in the downward pressure. The other end of the elastic member 1221 squeezes the pressure sensor 1224, enabling the pressure sensor 1224 to timely obtain the pressure of the elastic member 1221 on the magnet, and thus avoiding damaging the magnet due to excessive pressure.

[0037] As Figure 6 shown, the embodiment of the present utility model further includes a mounting bracket 13. The mounting bracket 13 includes: a mounting frame 131, to which both the horizontal feeding assembly 11 and the vertical press-fitting assembly 12 are connected; and a slide rail member disposed on the mounting bracket 13. The length direction of the slide rail member is parallel to the telescopic direction of the press-fitting cylinder 121. The slide rail member includes a slider connected to the vertical press-fitting assembly 12 and a slide rail on which the slider slides.

[0038] Specifically, the installation rack 131 is a cuboid frame structure, with a horizontal feeding component 11 arranged at its bottom, and a vertical pressing component 12 fixedly installed vertically between its top and bottom. The central axis of the horizontal feeding component 11 intersects and is perpendicular to the central axis of the vertical pressing component 12. Secondly, the elastic member 1221 and the long rod 123 are fixedly connected to the slider, and the slider can reciprocate up and down along the slide rail, enabling the elastic member 1221 and the long rod 123 to reciprocate up and down. Thus, during the process of the pressing cylinder 121 pressing down the magnet, the movement trajectories of the elastic member 1221 and the long rod 123 are fixed, and the magnet is pressed down.

[0039] As Figure 1 shown, the installation bracket 13 further includes a gun changing disk 132 arranged at the top end of the installation rack 131. An interface for connecting to the robot is formed on one side of the gun changing disk 132 away from the vertical pressing component 12; and an I / O-Link distributor arranged on the installation rack 131, which is electrically connected to the horizontal feeding component 11 and the vertical pressing component 12.

[0040] Specifically, the interface formed by the gun changing disk 132 is a standard interface. In the first embodiment, the present invention is connected to the robot through this interface, and the robot can be connected to magnet pressing mechanisms of different sizes through this interface, thereby expanding the applicable range of the robot. Secondly, the I / O-Link distributor allows two-way digital communication between sensors and actuators without complex wiring or high-end network infrastructure. It can connect multiple I / O-Link devices to a single I / O-Link master station port, thus reducing the number of required master station ports, simplifying the number of cables between devices, and constructing a more flexible, efficient, and easy-to-maintain industrial automation system.
