Description

Technical Field

[0001] This utility model relates to the technical field of magnet processing, and in particular to a device for processing irregularly shaped magnets. Background Technology

[0002] In high-end manufacturing fields such as new energy vehicles, precision motors, aerospace, and sensors, irregularly shaped magnets are core magnetic components, and their performance directly determines the operating efficiency, energy consumption level, and stability of end products. To meet the requirements of magnetic field control, assembly positioning, heat dissipation efficiency improvement, and weight reduction optimization, the surface of magnets needs to be machined with various shapes of grooves, such as arc grooves, trapezoidal grooves, and rectangular grooves. For example, toothed grooves optimize the magnetic field distribution to improve motor power density, dovetail grooves enable precise assembly to prevent high-speed displacement, and strip grooves increase the heat dissipation area to avoid magnetic performance attenuation. The machining quality of these grooves is crucial to the application value of magnets.

[0003] However, existing magnet processing technologies have the following shortcomings: each surface requires the machining of one or more different grooves, and each groove machining requires different cutting tools. This necessitates frequent tool changes during magnet processing, resulting in a low effective machining time ratio and cumbersome process connections. Furthermore, repeated tool disassembly and reassembly can lead to cumulative errors, affecting the dimensional accuracy of the grooves and the consistency of surface quality, making it difficult to meet the high-efficiency and precision requirements of high-end manufacturing for the mass production of irregularly shaped magnets. Therefore, this application proposes an irregularly shaped magnet processing device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a special-shaped magnet processing device that reduces the frequency of tool changes, thereby improving work efficiency and processing quality.

[0005] The objective of this utility model is achieved through the following technical solution: An apparatus for processing irregularly shaped magnets, comprising: Frame; A grinding assembly includes a slide rail, a cutter head, a cover ring, two pusher wheels, and several blades. The slide rail is mounted on a frame, and one end of the slide rail is connected to a conveyor belt. A guide channel is provided on the slide rail, extending through both ends of the slide rail. A pusher hole is provided on the slide rail. The two pusher wheels are rotatably mounted on the frame, located on the upper and lower sides of the slide rail, respectively. The outer wall of one pusher wheel is tangent to the top wall of the guide channel, and the outer wall of the other pusher wheel extends into the pusher hole and is tangent to the bottom surface of the guide channel. The slide rail also has an abrasive groove communicating with the guide channel. The cutter head is rotatably mounted on the frame, and each blade is coaxially fitted onto the cutter head. The cover ring is mounted on the cutter head, and the cover ring and the cutter head together clamp each blade. The cutter head drives each blade to extend into the abrasive groove.

[0006] Optionally, the slide rail includes a first guide rail, a second guide rail, and a third guide rail. The first guide rail, the second guide rail, and the third guide rail are each provided with a material groove. The two ends of the second guide rail are respectively connected to the first guide rail and the third guide rail, so that the material grooves together form the material guiding channel. The abrasive groove is provided on the third guide rail.

[0007] Optionally, the first guide rail is provided with an inlet, which is connected to the guide channel and is used to guide the magnet into the guide channel.

[0008] Optionally, the first guide rail is further provided with an arc-shaped portion, which is used to connect with the outer side of the conveyor belt.

[0009] Optionally, a notch is provided at one end of both the first guide rail and the second guide rail, and the two notches together form a lower notch, which is used to connect with the pusher wheel.

[0010] Optionally, the material trough is provided with a plurality of material chip troughs, each of which is located at one of the four corners of the material trough.

[0011] Optionally, a boss is provided on the bottom surface of the slide rail, and the boss is used to engage with the frame.

[0012] Optionally, the boss is provided with a plurality of screw holes, which are spaced apart and are used for fixed connection with the frame.

[0013] Compared with the prior art, the present invention has at least the following advantages: This utility model discloses a non-standard magnet processing device. The grinding assembly has a cutter head coaxially fitted with several blades. The cutter head drives each blade to fit into the abrasive groove of the slide rail, and the abrasive groove is connected to a guide channel that runs through the slide rail. When the magnet is conveyed to the abrasive groove via the guide channel, the blades simultaneously act on the surface of the magnet to be processed, completing multiple groove shapes in one operation. Simultaneously, the segmented design of the slide rail ensures stable material feeding, the pusher wheel assists in precise magnet feeding, and the stable connection between the boss and the frame ensures no displacement of the device during processing. This increases the effective processing time, improves processing efficiency, reduces cumulative errors caused by repeated tool disassembly and assembly, and improves processing quality.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0021] like Figures 1 to 8As shown, in one embodiment, a non-circular magnet processing device 1 is used to connect to a conveyor belt. It includes a frame 10 and a grinding assembly. The grinding assembly includes a slide rail 20, a cutter head 21, a cover ring 22, two pusher wheels 23, and several blades 24. The slide rail 20 is mounted on the frame 10, and one end of the slide rail 20 is connected to the conveyor belt (not shown in the figure). A guide channel 203 is provided on the slide rail 20, passing through both ends of the slide rail 20. A pusher hole 2002 is provided on the slide rail 20. Both pusher wheels 23 are rotatably mounted on the frame 10, and are located on the upper and lower sides of the slide rail 20, respectively. One of the pusher wheels 23... of The outer wall is tangent to the inner top wall of the guide channel 203. The outer wall of the other pusher wheel 23 extends into the pusher hole 2002 and is tangent to the bottom surface of the guide channel 203. The slide rail 20 is also provided with an abrasive groove 2020, which is connected to the guide channel 203. The cutter head 21 is rotatably mounted on the frame 10. Each blade 24 is coaxially mounted on the cutter head 21. The cover ring 22 is mounted on the cutter head 21. The cover ring 22 and the cutter head 21 together clamp each blade 24. The cutter head 21 drives each blade 24 to extend into the abrasive groove 2020.

[0022] It should be noted that the slide rail 20 is fixedly installed on the frame 10. The slide rail 20 has a material guide channel 203, which runs through both ends of the slide rail 20 axially. One end of the slide rail 20 is close to the conveyor belt, so that one end of the material guide channel 203 is connected to one end of the conveyor belt, thereby allowing the magnet to enter the material guide channel 203 under the conveyor belt. Furthermore, the guide channel 203 has a square structure with a rectangular cross-section; the inner top wall of the guide channel 203 is connected to the upper surface of the slide rail 20, making the cross-section of the guide channel 203 "C" shaped; furthermore, a push hole 2002 is provided on the slide rail 20, which extends vertically from the inner bottom wall of the guide channel 203 to the lower surface of the slide rail 20, making the push hole 2002 and the guide channel 203 "T" shaped; the length of the push hole 2002 along the axial direction of the slide rail 20 is greater than the thickness of the slide rail 20, so that the outer wall of the pusher wheel 23 can be tangent to the inner bottom wall of the guide channel 203; and the width of the push hole 2002 is less than the width of the guide channel 203, so that the two sides of the magnet can maintain communication with the guide channel. The inner bottom wall of the guide channel 203 abuts against the magnet, allowing the magnet to slide from one end of the guide channel 203 to the other, and the magnet can pass through the push hole 2002. Furthermore, both push wheels 23 are rotatably mounted on the frame 10 and are driven by motors (not shown in the figure), allowing the two push wheels 23 to rotate relative to the frame 10. The two push wheels 23 are located on the upper and lower sides of the slide rail 20, respectively. The outer wall of one push wheel 23 abuts against the upper surface of the magnet in the guide channel 203 from top to bottom, while the outer wall of the other push wheel 23 penetrates the push hole 2002 and abuts against the lower surface of the magnet in the guide channel 203. The axes of the two push wheels 23 and the axis of the push hole 2002 are both in a straight line and perpendicular to the guide channel 203. When the two pusher rollers 23 rotate in opposite directions (for example, the pusher roller 23 above the slide rail 20 rotates clockwise, and the pusher roller 23 below the slide rail 20 rotates counterclockwise), the two pusher rollers 23 together clamp the magnet, which can then drive the magnet to slide from one end of the pusher hole 2002 near the conveyor belt to the other end. Furthermore, the diameter of the pusher hole 2002 at the end near the bottom surface of the slide rail 20 is larger than the diameter at the other end, allowing the pusher roller 23 below the slide rail 20 to engage with the magnet. Near the guide channel 203; further, an abrasive groove 2020 is provided on the upper surface of the slide rail 20 away from the conveyor belt. The abrasive groove 2020 has an arc-shaped structure. The abrasive groove 2020 extends downward and connects with the guide channel 203, so that an arc-shaped notch is formed on the axial section of the guide channel 203. In this way, when the two pusher wheels 23 push each magnet to slide to the abrasive groove 2020 in sequence, the upward-facing surface of each magnet and its two opposite sides are exposed as they pass through the abrasive groove 2020.

[0023] It should be noted that the cutter head 21 is rotatably mounted on the frame 10 via a motor (not shown in the figure), and the cutter head 21 has a cutter groove 210 along the axial direction; each blade 24 has an annular structure, and the outer wall of each blade 24 is an irregularly shaped surface (for example, the outer wall of the blade 24 is an arc surface, a semi-circular convex surface, a semi-circular concave surface, a stepped surface, a U-shaped surface, or an L-shaped surface); furthermore, the cutter groove 210 has several equally angled fixing holes 211, and each blade 24 also has several equally angled fixing holes 211, and similarly, the cover ring 22 has several equally angled fixing holes 211. By passing screws sequentially through one fixing hole 211 on the cutter head 21, the cover ring 22, and each blade 24, and tightening them with nuts, the cover ring 22 and the cutter head 21 can simultaneously clamp each blade 24, preventing it from rotating. Furthermore, the cutter head 21 drives each blade 24 to extend into the abrasive groove 2020, so that when the cutter head 21 drives each blade 24 to rotate (it should be noted that the rotation direction of the pusher wheel 23 located below the slide rail 20 is the same as the rotation direction of the cutter head 21), each blade 24 can simultaneously grind the exposed surface of the magnet. In this way, the operator can combine the arrangement order of each blade 24 according to the actual grinding requirements of the product to achieve grinding of grooves of various shapes on one surface. This avoids frequent tool changes, increases the effective processing time, and reduces the cumulative error caused by multiple tool disassembly and assembly, which affects the dimensional accuracy of the groove and the consistency of surface quality, thus meeting the high-efficiency and precision requirements of high-end manufacturing for the mass production of irregularly shaped magnets.

[0024] It should be noted that when all sides of the magnet need to be machined, for ease of description, each side of the magnet is defined as the top surface, bottom surface, front side, rear side, left end face, and right end face. In one embodiment, the guide channel 203 has a horizontally oriented square cross-section. The magnet is slid into the guide channel 203 with its upper / lower surface facing upwards. The blades 24 on the cutter head 21 are combined to form a trapezoidal groove structure. Thus, under the combined pushing action of the two pusher wheels 23, when the magnet passes through the abrasive groove 2020, the blades 24 work together to polish the upper / lower surface of the magnet to form a trapezoidal structure.

[0025] In one embodiment, the cross-section of the guide channel 203 is a vertically oriented square structure. The magnet is slid into the guide channel 203 with its front / rear side facing upwards. The blades 24 on the cutter head 21 are combined to form a cross-section with irregularly shaped grooves (for example, from one side of the irregular groove, there are sequentially arranged L-shaped shallow grooves with rounded corners, semi-circular convex grooves, flat grooves, U-shaped grooves with rounded corners, flat grooves, and L-shaped deep grooves with rounded corners). Thus, under the pushing action of the two pusher wheels 23, when the magnet passes through the abrasive groove 2020, the blades 24 work together to grind the front / rear side of the magnet to form a structure with multiple irregularly shaped grooves.

[0026] In one embodiment, the magnet is slid into the guide channel 203 with its left / right end face facing upwards. The blades 24 on the cutter head 21 are combined to form a trapezoidal groove structure with arc-shaped sides on both sides. Thus, under the pushing action of the two pusher wheels 23, when the magnet passes through the abrasive groove 2020, the blades 24 work together to grind the left / right end face of the magnet to form the trapezoidal groove structure with arc-shaped sides on both sides.

[0027] like Figure 1 , Figures 4 to 8 As shown, in one embodiment, the slide rail 20 includes a first guide rail 200, a second guide rail 201, and a third guide rail 202. The first guide rail 200, the second guide rail 201, and the third guide rail 202 are each provided with a material groove 204. The two ends of the second guide rail 201 are respectively connected to the first guide rail 200 and the third guide rail 202, so that the material grooves 204 together form a material guiding channel 203. The abrasive groove 2020 is provided on the third guide rail 202.

[0028] It should be noted that the first guide rail 200, the second guide rail 201, and the third guide rail 202 are all fixedly installed on the frame 10, and the three are connected in sequence so that the material troughs 204 together form the guide channel 203. The first guide rail 200 is located at the end of the frame 10 closest to the conveyor belt. A half-groove 2001 is opened on the end where the first guide rail 200 and the second guide rail 201 are connected. When the two are connected, the two half-grooves 2001 together form the push hole 2002. The abrasive groove 2020 is opened on the third guide rail 202. In this way, the slide rail 20 is divided into the first guide rail 200, the second guide rail 201, and the third guide rail 202, so that the guide channel 203 inside is also divided into three sections. When the magnet gets stuck in the guide channel 203, the corresponding guide rail can be removed according to the actual situation, thereby reducing the abnormal handling time. Furthermore, since the two pusher wheels are fixed in position on the frame, during installation, the first guide rail and the second guide rail can be brought closer to each other from both radial sides of the pusher wheel to complete the connection, thus improving installation efficiency.

[0029] like Figure 1 , Figure 4 , Figure 7 As shown, in one embodiment, the first guide rail 200 is provided with an inlet 2003, which is connected to the guide channel 203. The inlet 2003 is used to guide the magnet into the guide channel 203.

[0030] It should be noted that an inlet 2003 is provided on the end of the first guide rail 200 furthest from the second guide rail 201. The diameter of the inlet 2003 gradually decreases from the end of the first guide rail 200 closest to the conveyor belt towards the second guide rail 201, and is connected to the guide channel 203. This allows the conveyor belt to quickly guide the magnets into the guide channel 203, preventing magnets from accumulating in the inlet 2003 and affecting processing efficiency.

[0031] like Figure 1 , Figure 4 , Figure 7 , Figure 8 As shown, in one embodiment, the first guide rail 200 is further provided with an arc-shaped portion 2004, which is used to connect with the outer wall of the conveyor belt.

[0032] It should be noted that an arc-shaped portion 2004 is provided on the bottom surface of the first guide rail 200 near the conveyor belt. The curvature of the arc-shaped portion 2004 is adapted to the curvature of the end face of the conveyor belt. Thus, when the end of the first guide rail 200 with the inlet 2003 is close to the conveyor belt, the arc-shaped portion 2004 can adaptably avoid the outer wall of the end of the conveyor belt, so that the inner bottom wall of the guide channel 203 is in a parallel connection with the conveyor belt conveying surface, thereby enabling the conveyor belt to transport the magnet into the guide channel 203.

[0033] like Figure 1 , Figure 4 , Figures 6 to 8 As shown, in one embodiment, a notch 2005 is provided on one end of the first guide rail 200 and the second guide rail 201. The two notches 2005 together form a lower notch 2006, which is used to connect with the pusher wheel 23.

[0034] It should be noted that a notch 2005 is provided on the bottom surface of the end of the first guide rail 200 and the second guide rail 201 that are close to each other. When the first guide rail 200 and the second guide rail 201 are both set on the frame 10 and connected to each other, the two notches 2005 together form a complete lower notch 2006. The axis of the lower notch 2006 is perpendicular to the direction of movement of the magnet and is connected to the push hole 2002. In this way, the lower notch 2006 forms a clearance structure relative to the slide rail 20 to avoid the lower push wheel 23, so that the outer side wall of the lower push wheel 23 can approach the guide channel 203.

[0035] like Figure 4 , Figure 5 , Figure 7 As shown, in one embodiment, a plurality of chip troughs 205 are provided in the material trough 204, and each chip trough 205 is located at one of the four corners of the material trough 204.

[0036] It should be noted that the cross-section of the material trough 204 is square, and the material troughs 204 are connected end to end to form the material guide channel 203. Each chip groove 205 is located at one of the four corners of the material trough 204, and the opening direction of each chip groove 205 is consistent with that of the material trough 204. Furthermore, each chip groove 205 connects to both ends of the axial direction of the material guide channel 203, and its side structure is also connected to the material trough 204. When the magnet slides appropriately within the material guide channel 203, the four corners of the magnet are in a state of clearance. Thus, when the tool grinds one surface of the magnet, waste material can enter the chip groove 205 from the material trough 204, thereby preventing waste material from accumulating in the material guide channel 203 and affecting the sliding of the magnet within the material guide channel 203.

[0037] like Figure 1 , Figure 5 , Figure 8 As shown, in one embodiment, a boss 206 is provided on the bottom surface of the slide rail 20, and the boss 206 is used to engage with the frame 10.

[0038] It should be noted that a boss 206 is provided on the bottom surface of the slide rail 20 (i.e. the side of the first guide rail 200, the second guide rail 201 and the third guide rail 202 away from the material trough 204), and a corresponding slot is provided on the frame 10; when the slide rail 20 drives the boss 206 to engage with the slot, the slide rail 20 cannot slide relative to the frame 10.

[0039] like Figure 8 As shown, in one embodiment, the boss 206 is provided with a plurality of screw holes 207, which are spaced apart and are used to fix and connect with the frame 10.

[0040] It should be noted that the boss 206 has several screw holes 207, which are spaced apart. Specifically, the first guide rail 200, the second guide rail 201, and the third guide rail 202 all have several screw holes 207. Each screw hole 207 is screwed to the frame 10 by screws, so that the first guide rail 200, the second guide rail 201, and the third guide rail 202 are fixedly installed on the frame 10.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
