Description

Technical Field

[0001] This utility model relates to the field of chamfering technology for ring components, and more specifically, to a ring chamfering mechanism. Background Technology

[0002] Magnets are generally manufactured using powder metallurgy, and after production, they are ground by a grinding machine. Grinding is the most common and widely used machining process. Most workpieces need to be ground to the required shape on their outer surface or at corners.

[0003] In some specialized applications, magnets are often processed into ring-shaped structures, requiring chamfering at both the top and bottom edges of the outer edge and the top and bottom edges of the inner hole. Current technology typically involves multiple chamfering machines performing multiple chamfering operations, with transfer boxes needed between different chamfering processes. This not only occupies a large space but also wastes significant manpower and resources during the transfer process, leading to increased processing costs and low processing efficiency. Utility Model Content

[0004] To overcome at least one of the defects in the prior art, this utility model provides a ring chamfering mechanism that can realize automatic workpiece conveying and can perform chamfering of the outer edge and inner hole on a single machine, simplifying processing equipment, reducing labor costs and improving work efficiency.

[0005] The technical solution adopted by this utility model is to provide a circular chamfering mechanism: including a main frame, on which are provided an outer edge chamfering component, a material transfer mechanism, a second conveyor belt, a first inner hole chamfering component, a flipping component, and a second inner hole chamfering component. The material transfer mechanism is used to move the workpiece to the outer edge chamfering component and to move the workpiece with the outer edge chamfered to the second conveyor belt. The first inner hole chamfering component is used to clamp the workpiece on the second conveyor belt and achieve chamfering at the first end of the inner hole. The flipping component is used to clamp the workpiece with the first end of the inner hole chamfered on the second conveyor belt and flip it over. The second inner hole chamfering component is used to clamp the workpiece with the flipped surface on the second conveyor belt and achieve chamfering at the second end of the inner hole.

[0006] Compared with the prior art, the circular chamfering mechanism of this utility model has the following advantages:

[0007] This utility model discloses a ring chamfering mechanism, a dedicated chamfering mechanism with a ring structure. It includes an outer edge chamfering assembly, a material transfer mechanism, and a second conveyor belt. The material transfer mechanism moves the workpiece from its initial position to the outer edge chamfering assembly and then moves the chamfered workpiece onto the second conveyor belt. Additionally, a first inner hole chamfering assembly, a flipping assembly, and a second inner hole chamfering assembly are positioned on the main frame corresponding to the second conveyor belt. During the process, after the workpiece is transferred to the second conveyor belt after outer edge chamfering, it moves forward as the second conveyor belt runs. The first inner hole chamfering assembly first picks up the chamfered workpiece from the second conveyor belt and performs inner hole chamfering. The first end of the hole is chamfered. After chamfering, the workpiece is placed back on the second conveyor belt and continues to move forward. When it moves to the position of the flipping component, the flipping component is used to clamp the workpiece and flip its upper and lower end faces. After flipping, the workpiece is placed back on the second conveyor belt and continues to move forward. When it moves to the position of the second inner hole chamfering component, the second inner hole chamfering component clamps the workpiece on the second conveyor belt and chamfers its inner hole second end. Then it is placed back on the second conveyor belt, thus realizing the chamfering treatment of the upper and lower ends of the inner hole of the workpiece. The whole process adopts a continuous assembly line processing procedure with a tight rhythm, automatic chamfering, no manual intervention, and high work efficiency.

[0008] Furthermore, the material transfer mechanism includes a mounting bracket, on which a sliding plate capable of sliding horizontally is connected and a sliding plate drive unit for driving the sliding plate to slide back and forth is connected.

A pressure driving cylinder is connected to the first sliding plate or the first fixing plate. The pressure plate is connected to the piston rod of the pressure driving cylinder. The pressure plate is located inside each of the first grippers, and the outer diameter of the pressure plate is smaller than the outer diameter of the workpiece.

[0012] Furthermore, the second clamping assembly includes a second mounting base, on which a second servo motor, a second lead screw, a second lead screw slider, and a vertically slidable second sliding plate are connected. The second lead screw is driven and connected to the second servo motor, the second lead screw slider is helically engaged outside the second lead screw, and the second sliding plate is connected to the second lead screw slider. A second fixing plate is also connected to the second mounting base below the second sliding plate.

A second linkage plate is hinged to each second gripper, and the end of each second linkage plate away from the second gripper is respectively hinged to the outer peripheral wall of the second sliding plate.

[0013] Furthermore, the first and second inner hole chamfering components have the same structure, both including a first gantry bracket spanning above the second conveyor belt. A first lifting plate and a first lifting drive unit for driving its lifting are connected to the crossbeam of the first gantry bracket. Two opposing first clamping blocks and a first clamping drive unit for driving the two first clamping blocks to move closer and further apart are connected to the first gantry bracket. A vertical slide and a second lifting drive unit for driving its lifting are also connected to the crossbeam of the first gantry bracket.

Detailed Implementation

[0023] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0024] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "fixed" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0025] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] See Figures 1-6As shown in the figure, this application discloses a circular chamfering mechanism, including a rectangular main frame 1. The main frame 1 is provided with an outer edge chamfering component 3, a material transfer mechanism, a second conveyor belt 4, a first inner hole chamfering component 7, a flipping component 8, and a second inner hole chamfering component 9. The material transfer mechanism is used to move the workpiece to the outer edge chamfering component 3 and to move the workpiece with the outer edge chamfered to the second conveyor belt 4. The first inner hole chamfering component 7 is used to clamp the workpiece on the second conveyor belt 4 and chamfer the first end of the inner hole. The flipping component 8 is used to clamp the workpiece with the first end of the inner hole chamfered on the second conveyor belt 4 and flip it up and down. The second inner hole chamfering component 9 is used to clamp the workpiece with the flipped surface on the second conveyor belt 4 and chamfer the second end of the inner hole. This allows the workpiece to have both outer edge chamfered and both inner circle chamfered on one machine, simplifying the processing steps and improving work efficiency.

[0027] In this embodiment, preferably, a first conveyor belt 3 is also provided on the main frame 1 to realize automatic feeding of the workpiece to be processed. In this way, the entire process of the workpiece from feeding to outer edge chamfering and then inner circle chamfering is automated and continuously conveyed, effectively improving work efficiency. In some other embodiments, the upper end of the first conveyor belt 3 can be directly connected to the discharge end of the previous process.

[0028] In the above structure, the material transfer mechanism includes a mounting bracket 10, on which a sliding plate 11 capable of sliding horizontally is connected and a sliding plate drive unit for driving the sliding plate 11 to slide back and forth is connected. A first clamping assembly 5 and a second clamping assembly 6 are connected on the sliding plate 11. When the first clamping assembly 5 is used to clamp the workpiece to be processed and move it above the outer edge chamfering assembly 3, the second clamping assembly 6 is used to clamp the chamfered workpiece on the outer edge chamfering assembly 3 and move it onto the second conveyor belt 4. More specifically, when the first workpiece is conveyed by the first conveyor belt 2, the first clamping assembly 5 clamps the workpiece and transfers it to the outer edge chamfering assembly 3 for chamfering of both the upper and lower edges. After the outer edge chamfering is completed, the first clamping assembly 5 returns to its original position above the discharge end of the first conveyor belt 2 to clamp the second workpiece. At the same time, the second clamping assembly 6 clamps the chamfered workpiece on the outer edge chamfering assembly 3. Then, the first clamping assembly 5 moves the clamped second workpiece toward the position of the outer edge chamfering assembly 3. Meanwhile, the second clamping assembly 6 moves the first workpiece with the chamfered outer edge to the feed end of the second conveyor belt 4. With the continuous reciprocating motion of the first clamping assembly 5 and the second clamping assembly 6, the workpieces on the first conveyor belt 2 are moved sequentially to the outer edge chamfering assembly 3 for chamfering and transferred to the second conveyor belt 4 for the next chamfering action.

[0029] See appendix Figure 3The skateboard drive unit includes a connecting rod 12, a connecting plate 13, and a drive motor 14. The drive motor 14 is connected to the mounting bracket 10. One end of the connecting plate 13 is fixedly connected to the output shaft of the drive motor 14. The other end of the connecting plate 13 is hinged to one end of the connecting rod 12, and the other end of the connecting rod 12 is hinged to one end of the skateboard 11. Preferably, the mounting bracket 10 is a portal frame mounting bracket. Two vertically distributed and parallel linear guide rails are connected to the crossbeam of the portal frame mounting bracket. Several linear sliders are connected to each of the two linear guide rails. The slide plate 11 is connected to several linear sliders to achieve smooth movement. In addition, the connecting plate 13 also rotates in the plane along the direction of movement of the slide plate 11. Here, the connecting plate 13 acts like an eccentric wheel. That is, as the drive motor 14 runs, it drives the connecting plate 13 to rotate, which in turn drives the connecting rod 12 to drive the slide plate 11 to reciprocate along the length of the crossbeam. Finally, the first clamping assembly 5 and the second clamping assembly 6 reciprocate, driving the continuously fed workpieces to automatically and continuously flow backward on the production line.

[0030] Additionally, the main frame 1 is sequentially connected to a first inner hole chamfering assembly 7, a flipping assembly 8, and a second inner hole chamfering assembly 9 located above the second conveyor belt 4. Here, "above" is not limited to directly above the second conveyor belt 4, but can also be above its side. Specifically, the first inner hole chamfering assembly 7 is used to clamp the workpiece on the second conveyor belt 4 and chamfer the first end of the inner hole, the flipping assembly 8 is used to clamp the workpiece on the second conveyor belt 4 after the first end of the inner hole has been chamfered and flip it over, and the second inner hole chamfering assembly 9 is used to clamp the workpiece on the second conveyor belt 4 after it has been flipped over and chamfer the second end of the inner hole. Throughout the process, after the workpiece is chamfered at the outer edge and transferred to the second conveyor belt 4, it moves forward as the second conveyor belt 4 runs. The first inner hole chamfering component 7 first clamps the workpiece on the second conveyor belt 4 and chamfers the upper end of its inner hole. After chamfering, the workpiece is placed back on the second conveyor belt 4 and continues to be conveyed forward. When it moves to the position of the flipping component 8, the flipping component 8 is used to clamp the workpiece and flip its upper and lower end faces. After flipping, the workpiece is placed back on the second conveyor belt 4 and continues to move forward. When it moves to the position of the second inner hole chamfering component 7, it continues to move forward. When the corner component 9 is in position, the second inner hole chamfering component 9 clamps the workpiece on the second conveyor belt 4 and chamfers the upper end of its inner hole. Then it is placed back on the second conveyor belt 4, thereby achieving the chamfering treatment of the upper and lower ends of the inner hole of the workpiece. The whole process adopts a continuous assembly line processing procedure. Workpieces with chamfered outer edges are conveyed on the second conveyor belt 4 at intervals, so that the inner hole chamfering of the two end faces can be completed on the workpiece on the second conveyor belt 4 during the movement. The rhythm is compact, the chamfering is automatic, no manual intervention is required, and the work efficiency is high.

[0031] Additionally, in this embodiment, see Appendix Figure 1 , 2The outer edge chamfering assembly 3 includes a workpiece support platform 300 and a first drive unit 301 for driving the workpiece support platform 300 to rotate horizontally. The first clamping assembly 5 is provided with a pressure plate 302 that can move up and down and rotate around its own axis. When the workpiece moves from the first conveyor belt 2 to the workpiece support platform 300, the pressure plate 302 moves down and presses against the upper end of the workpiece. The first drive unit 301 is used to drive the workpiece to rotate around its axis. Furthermore, an outer edge chamfering grinding wheel 303, a second drive unit 304 for driving the outer edge chamfering grinding wheel 303 to rotate, and a mechanism for driving the outer edge chamfering grinding wheel are also connected to the rear side of the workpiece support platform 300 on the main frame 1. 303 moves closer to and further away from the workpiece support table 300. More specifically, a chamfering groove 306 is recessed on the outer peripheral wall of the outer chamfering grinding wheel 303. The cross-section of the chamfering groove 306 is trapezoidal, and the width of the opening end is greater than the width of its bottom. Therefore, when the workpiece is positioned between the workpiece support table 300 and the pressure plate 302, when the translation drive unit 305 drives the outer chamfering grinding wheel 303 to move forward to the chamfering position, the two side walls of the chamfering groove 306 at this position are respectively in contact with the outer edges of the two ends of the workpiece. With the operation of the first drive unit 301 and the second drive unit 304, the upper and lower ends of the outer edge of the workpiece are simultaneously chamfered. Preferably, the first drive unit 301 and the second drive unit 304 are both servo motor sets with reducers, and the translation drive unit 305 is a dovetail groove support plate structure with motor drive. The outer edge chamfering grinding wheel 303 and the second drive unit 304 can move back and forth synchronously through motor drive to ensure that the chamfering groove 306 of the outer edge chamfering grinding wheel 303 is accurately aligned with the outer edge of the workpiece.

[0032] On the other hand, see Appendix Figure 3In this embodiment, the first clamping assembly 5 includes a first mounting base 501. A first servo motor 502, a first lead screw 503, a first lead screw slider 504, and a vertically slidable first sliding plate 505 are connected to the first mounting base 501. The first lead screw 503 is driven by the first servo motor 502. The first lead screw slider 504 is helically engaged with the outside of the first lead screw 503, and the first sliding plate 505 is connected to the first lead screw slider 504. A first fixing plate 506 is also connected to the first mounting base 501 below the first sliding plate 505. Specifically, the first fixing plate 506 is connected to the first mounting base 501 via multiple circumferentially distributed and vertically extending connecting rods. A connecting rod slides through the first sliding plate 505; at least two first grippers 507 that can be folded up and down are hinged to the outer periphery of the first fixed plate 506. Preferably, there are three first grippers 507, which are evenly distributed along the circumference; each first gripper 507 is hinged to a first linkage plate 508, and the end of each first linkage plate 508 away from the first gripper 507 is respectively hinged to the outer peripheral wall of the first sliding plate 505; the operation of the first servo motor 502 drives the first lead screw slider 504 to move the first sliding plate 505 up and down, and then the three first linkage plates 508 drive the three first grippers 507 to rotate downward to clamp the outer wall of the workpiece, or to rotate upward to release and detach from the outer wall of the workpiece.

[0033] In addition, a pressure-driven cylinder 509 is connected to the first sliding plate 505 in the above structure. The pressure plate 302 is connected to the piston rod of the pressure-driven cylinder 509. Specifically, a bearing is connected to the lower end of the piston rod of the pressure-driven cylinder 509. A mounting hole is opened in the middle of the pressure plate 302, and the outer ring of the bearing is fixed in the mounting hole, thereby realizing the rotation of the pressure plate 302. This ensures that when the workpiece is chamfered at the outer edge, the pressure plate 302 is always pressed against the upper surface of the workpiece, ensuring the accuracy of the chamfer position and improving the product qualification rate. The pressure plate 302 is located inside each of the first grippers 507, and the outer diameter of the pressure plate 302 is smaller than the outer diameter of the workpiece. When the first clamping assembly 5 clamps the workpiece on the first conveyor belt 2 and moves it onto the workpiece support platform 300, the pressure drive cylinder 509 drives the pressure plate 302 to move down and press against the upper end face of the workpiece. After the workpiece is positioned, the three first grippers 507 release, and the outer edge chamfering grinding wheel 303 approaches the workpiece to perform a chamfering operation. In some other embodiments, the pressure drive cylinder 509 can also be connected to the first fixed plate 506, provided that it does not interfere with the clamping process of each of the first grippers 507.

[0034] Similarly, the second clamping assembly 6 in this embodiment has most of the same structure as the first clamping assembly 5, the only difference being that the second clamping assembly 6 does not require a pressing structure. Specifically, the second clamping assembly 6 includes a second mounting base 601, on which a second servo motor, a second lead screw, a second lead screw slider, and a vertically slidable second sliding plate are connected. The second lead screw is driven and connected to the second servo motor, the second lead screw slider is helically engaged with the outside of the second lead screw, and the second sliding plate is connected to the second lead screw slider. A second fixing plate is also connected to the second mounting base 601 below the second sliding plate. Three second grippers that can be folded up and down are hinged to the outer periphery of the second fixing plate. Each second gripper is hinged with a second linkage plate, and the end of each second linkage plate away from the second gripper is respectively hinged to the outer peripheral wall of the second sliding plate. The clamping principle of the second clamping assembly 6 is the same as that of the first clamping assembly 5, and will not be described again here.

[0035] For others, see Appendix Figure 4 and 5 In this embodiment, the first inner hole chamfering assembly 7 and the second inner hole chamfering assembly 9 have the same structure, both including a first gantry bracket 701 spanning above the second conveyor belt 4. A first lifting plate 702 and a first lifting drive unit 703 for driving its lifting and lowering are connected to the crossbeam of the first gantry bracket 701. Two opposing first clamping blocks 704 and a first clamping drive unit 705 for driving the two first clamping blocks 704 to move closer and further apart are connected to the first lifting plate 702. A vertical slide block 706 and a second lifting drive unit 707 for driving its lifting and lowering are also connected to the crossbeam of the first gantry bracket 701. A vertically arranged chamfering motor 708 is connected to the vertical slide block, and a tapered inner hole chamfering grinding head 709 is connected to the output shaft of the chamfering motor 708. Preferably, two sets of vertically arranged linear guide rail assemblies are connected to the crossbeam of the first gantry bracket 701, and a first sliding plate 505 is connected to the slider of one of the linear guide rail assemblies. Here, the first lifting drive unit is a cylinder structure. In other embodiments, the first lifting drive unit may also be a hydraulic cylinder or a linear motor. Similarly, the vertical slide 706 is connected to the slider of another set of linear guide assemblies.

[0036] Additionally, a horizontally arranged linear guide rail is connected to the front side wall of the first lifting plate 702, and two first clamping blocks 704 are respectively connected to the corresponding linear guide rails via sliders; the first clamping drive unit 705 is horizontally connected to the rear side wall of the first lifting plate 702, and includes a horizontally arranged clamping motor, a lead screw, and two lead screw nuts, with the threads of the two lead screw nuts having opposite directions. The two sliders are respectively connected to the two lead screw nuts, that is, when the clamping motor drives the lead screw to rotate, the two lead screw nuts with opposite directions of rotation move closer to each other or further away from each other, thereby driving the two sliders and the corresponding first clamping blocks 704 to move closer to and further away, so as to achieve the function of clamping and releasing the workpiece.

[0037] In the above structure, the first lifting drive unit 703 drives the first lifting plate 702 to rise and fall, thereby clamping the workpiece; the second lifting drive unit 707 drives the chamfering motor 708 to rise and fall, mainly to adjust the chamfering position of the workpiece. Specifically, during clamping, the first lifting drive unit 703 drives the first lifting plate 702 to descend to the clamping position, and the two first clamping blocks 704 clamp the workpiece. Then, the first lifting drive unit 703 drives the first lifting plate 702 to rise to the working position, and the second lifting drive unit 707 drives the chamfering motor 708 to descend until the inner hole chamfering grinding head 709 contacts the end of the inner hole of the workpiece. As the inner hole chamfering grinding head 709 rotates, the second lifting drive unit 707 continues to drive the chamfering motor 708 to descend until the workpiece is chamfered to the required size. In this structure, since the descent of the inner hole chamfering grinding head 709 is used for the chamfering amount feed, the accuracy requirement is higher. Therefore, the second lifting drive unit 707 here adopts a servo motor combined with a lead screw pair structure for driving.

[0038] On the other hand, participating in the attached Figure 4 In this embodiment, a horizontal mounting plate 710 is also connected to the first lifting plate 702. The mounting plate 710 has a clearance through hole for the inner hole chamfering grinding head 707 to pass through, and a dust collection hood (not shown in the figure) surrounding the inner hole chamfering grinding head 709 is connected to the mounting plate 710. The dust collection hood is connected to a dust collection pipe (not shown in the figure) that communicates with an external adsorption device. This structure realizes automatic dust removal during the chamfering grinding process and improves the workshop working environment.

[0039] See appendix Figure 6The flipping assembly 8 includes a second gantry bracket 801 spanning above the second conveyor belt 4. A second lifting plate 802 is connected to the crossbeam of the second gantry bracket 801, and a third lifting drive unit 803 is used to drive the second lifting plate 802 to move up and down. Two oppositely arranged fixed seats 804 and a second clamping drive unit 805 are connected to the second lifting plate 802 to drive the two fixed seats 804 to move closer and further apart from each other. Rotary drivers 806 are connected to the inner walls of the two fixed seats 804, and the driving ends of the two rotary drivers 806 are connected to second clamping blocks 807. After the inner hole at one end of the workpiece is chamfered, the third lifting drive unit 803 drives the second lifting plate 802 to descend until the two second clamping blocks 807 are located outside the workpiece. The second clamping drive unit 805 drives the two fixed seats 804 to move closer together to clamp the workpiece. Then, the second lifting plate 802 is raised to a set height, and the two rotary drives 806 operate to flip the upper and lower ends of the workpiece. Then, the second lifting plate 802 descends again to the clamping height, the two fixed seats 804 move away from each other, and the second clamping blocks 807 release the clamping limit on the workpiece. The workpiece continues to move forward until the second clamping assembly 6 grips the workpiece and completes the chamfering of the inner hole at the other end. In this structure, the second clamping drive unit 805 has the same structure as the first clamping drive unit 705, and will not be described again here. In addition, since the second lifting plate 802 only needs to ensure that it can grasp the workpiece in this structure, there is no requirement for adjustment accuracy, so the third lifting drive unit 803 can be a pneumatic cylinder, hydraulic cylinder, or electric cylinder.
