Description

Technical Field

[0001] This utility model relates to the field of magnetic material grinding machines, and in particular to an automatic adjustment feeding mechanism for magnetic material grinding machines. Background Technology

[0002] Currently, irregularly shaped magnetic materials are widely used in the electromechanical industry both domestically and internationally. As the requirements for electromagnetic industrial products continue to increase, the precision and dimensions of magnets are also becoming increasingly demanding. In large-scale production, after the magnetic tiles complete the pressing, forming, and sintering processes, they enter the grinding process. The grinding process of magnetic tiles includes: grinding the two planes of the chord width and the bottom plane, grinding the two end faces of the axial length, and rough and fine grinding of the inner and outer arc surfaces.

[0003] In the existing technology, irregularly shaped magnetic materials are fed by upper and lower shaft rubber wheels and rotary extrusion. If the raw material size is too large (the product is formed by wet or dry pressing molds, and the product size deviates due to different shrinkage after demolding), it will cause great damage to the rubber wheels or shafts, requiring frequent replacement of vulnerable parts. If the size is too small, it will cause the feeding to be weak and slip, and the feeding will be interrupted. Therefore, an automatic adjustment feeding mechanism for magnetic material grinding machines is proposed. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Better compatibility with differences in the shape of magnetic materials. The magnetic material is pushed onto the inner arc guide rail and the bottom of the magnetic material is used as the reference surface. When the inner cavity formed by the arching inside the magnetic material has too large a height difference with the reference surface, causing the upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism to not act on the contact area of ​​the upper and lower surfaces of the magnetic material at the same time, the second transmission screw is driven to rotate by the third motor and the first transmission screw is driven to rotate by the fourth motor. During the rotation of the second transmission screw, the upper rubber wheel transmission mechanism is moved to a different position. Similarly, during the rotation of the first transmission screw, the lower rubber wheel transmission mechanism is moved to a different position. This reduces the gap between the upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism, so that the upper rubber wheel transmission mechanism adapts to the height of the outside of the magnetic material and the lower rubber wheel transmission mechanism adapts to the height of the inner cavity of the magnetic material. Thus, the upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism can act on the contact area outside the magnetic material and the contact area inside the contact area outside the magnetic material at the same time, respectively.

[0017] Conversely, when the height difference between the inner cavity formed by the arching inside the magnetic material and the reference surface is too small, causing the upper and lower rubber wheel drive mechanisms to not act simultaneously on the contact areas of the upper and lower surfaces of the magnetic material, the upper and lower rubber wheel drive mechanisms are driven by the third and fourth motors to increase the gap between them.

[0018] (2) Better feeding of magnetic materials. When the upper and lower rubber wheel drive mechanisms have acted on the expected contact area of ​​the magnetic materials respectively, the upper and lower rubber wheel drive mechanisms simultaneously rotate and squeeze the magnetic materials, thereby pressing different types of magnetic materials onto the inner arc guide rail and pushing the magnetic materials forward.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7In this embodiment of the invention, the automatic adjustment feeding mechanism of the magnetic material grinding machine includes a support frame 1 and a vertical plate 2 located laterally on the front side of the support frame 1. An upper rubber wheel transmission mechanism for extruding and transmitting magnetic material is movably arranged at the upper end of the front side of the vertical plate 2, and a lower rubber wheel transmission mechanism that synchronously drives the upper rubber wheel transmission mechanism is arranged at the lower end of the front side of the vertical plate 2. A feeding gap is formed between the upper and lower rubber wheel transmission mechanisms for the magnetic material to pass through, and an inner arc guide rail 4 supporting the movement of the magnetic material is mounted across the feeding gap. A rubber wheel translation mechanism is arranged at the top back of the vertical plate 2 to drive the distance between the upper and lower rubber wheel transmission mechanisms in the feeding gap. The rubber wheel translation mechanism includes a fixed platform (not shown in the figure) set on the back of the upright plate 2, and a third motor 19 for driving the upper rubber wheel transmission mechanism to move up and down and a fourth motor 20 for driving the lower rubber wheel transmission mechanism to move up and down are respectively set on both sides of the top of the fixed platform. The third motor 19 is equipped with a second transmission screw 26 for driving the upper rubber wheel transmission mechanism to move longitudinally, and the fourth motor 20 is equipped with a first transmission screw 22 for driving the lower rubber wheel transmission mechanism to move longitudinally. The upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism move up and down with the upper and lower surfaces of the inner arc guide rail 4 respectively, and the upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism close or separate from the upper and lower surfaces of the inner arc guide rail 4 respectively.

[0031] Therefore, in specific application scenarios, the following working effects can be achieved through the movement and coordination between the upper and lower rubber wheel transmission mechanisms:

[0032] (1) Better compatibility with differences in the shape of magnetic materials. The magnetic material is pushed onto the inner arc guide rail 4 with the bottom end of the magnetic material as the reference surface. When the inner cavity formed by the arching inside the magnetic material has too large a height difference with the reference surface, causing the upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism to not act on the contact area of ​​the upper and lower surfaces of the magnetic material at the same time, the second transmission screw 26 is driven to rotate by the third motor 19 and the first transmission screw 22 is driven to rotate by the fourth motor 20. During the rotation of the second transmission screw 26, the position of the upper rubber wheel transmission mechanism is changed. Similarly, during the rotation of the first transmission screw 22, the position of the lower rubber wheel transmission mechanism is changed. This reduces the gap between the upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism, so that the upper rubber wheel transmission mechanism adapts to the height of the outside of the magnetic material and the lower rubber wheel transmission mechanism adapts to the height of the inner cavity of the magnetic material. Thus, the upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism can act on the contact area outside the magnetic material and the contact area inside the contact area outside the magnetic material at the same time, respectively. Conversely, when the height difference between the inner cavity formed by the arching inside the magnetic material and the reference surface is too small, causing the upper and lower rubber wheel transmission mechanisms to not act simultaneously on the contact areas of the upper and lower surfaces of the magnetic material, the upper and lower rubber wheel transmission mechanisms are driven by the third motor 19 and the fourth motor 20 to increase the gap between the upper and lower rubber wheel transmission mechanisms.

[0033] (2) Better feeding of magnetic materials. When the upper rubber wheel drive mechanism and the lower rubber wheel drive mechanism have acted on the expected contact area of ​​the magnetic material respectively, the upper rubber wheel drive mechanism and the lower rubber wheel drive mechanism simultaneously rotate and squeeze the magnetic material, thereby pressing different types of magnetic materials on the inner arc guide rail 4 and pushing the magnetic material forward.

[0034] The upright plate 2 is provided with a rubber wheel drive mechanism that drives and cooperates with the upper rubber wheel drive mechanism and the lower rubber wheel drive mechanism. The rubber wheel drive mechanism includes a fixed platform 23 that is horizontally installed at the bottom of the back of the upright plate 2. The bottom of the fixed platform 23 is provided with a second motor 17 that drives the upper rubber wheel drive mechanism and the lower rubber wheel drive mechanism to operate. The second motor 17 is provided with a drive shaft 13 that drives and cooperates with the upper rubber wheel drive mechanism and the lower rubber wheel drive mechanism. Thus, the upper rubber wheel drive mechanism and the lower rubber wheel drive mechanism are driven by the drive cooperation between the second motor 17 and the drive shaft 13 to rotate, squeeze and push the magnetic material that is horizontally placed on the inner arc guide rail 4.

[0035] The upright plate 2 is also provided with guide rails 10 that slide in cooperation with the upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism. The guide rails 10 are both vertically located on the left and right sides of the back of the upright plate 2. The upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism are respectively mounted on the upper and lower ends of the guide rails 10, and the upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism slide up and down through the guide rails 10 at the upper and lower ends of the back of the upright plate 2.

[0036] The rubber wheel translation mechanism also includes an upper rubber wheel fixing plate 21 that moves synchronously with the upper rubber wheel transmission mechanism. The upper rubber wheel fixing plate 21 is driven to the second transmission screw 26. An elastic linkage mechanism is provided between the upper rubber wheel fixing plate 21 and the upper rubber wheel transmission mechanism. When the third motor 19 drives the second transmission screw 26 to rotate and drives the upper rubber wheel fixing plate 21 to move longitudinally, the upper rubber wheel transmission mechanism is elastically moved up and down at the upper end of the front side of the upright plate 2 through the elastic linkage mechanism, so as to ensure that the upper rubber wheel transmission mechanism always maintains a sufficiently stable bearing force on the magnetic material.

[0037] The upper rubber wheel transmission mechanism includes an upper rubber wheel lifting platform 11 that moves longitudinally on the vertical plate 2, and the upper rubber wheel lifting platform 11 is elastically connected to an elastic linkage mechanism. A first rubber wheel 8 is provided on one side of the upper rubber wheel lifting platform 11 and moves longitudinally synchronously with it on the vertical plate 2. The upper rubber wheel lifting platform 11 is provided with a first transmission shaft 29 that drives the first rubber wheel 8 to rotate on the vertical plate 2, thereby causing the upper rubber wheel lifting platform 11 and the first rubber wheel 8 to move longitudinally on the vertical plate 2 until they contact the magnetic material on the inner arc guide rail 4 and press the magnetic material onto the inner arc guide rail 4. At the same time, the first transmission shaft 29 drives the first rubber wheel 8 to rotate and pushes the magnetic material pressed on the inner arc guide rail 4 forward. The first transmission shaft 29 is driven by a drive shaft 13, and the first transmission shaft 29 is provided with a third bevel gear 28 that rotates coaxially with it and the drive shaft 13. At the upper end of the 3, a first bevel gear 24 is also provided, which rotates coaxially with the third bevel gear 28 and meshes with it. When the second motor 17 drives the drive shaft 13 to rotate, it also drives the third bevel gear 28 to rotate. Then, through the meshing between the first bevel gear 24 and the third bevel gear 28, the first transmission shaft 29 is driven to rotate along with the first rubber wheel 8. The upper rubber wheel lifting platform 11 is provided with a limiting frame 18 that moves synchronously with it. The limiting frame 18 is located horizontally at the top of the front side of the upright plate 2, and the limiting frame 18 is parallel to the inner arc guide rail 4. Thus, when the upper rubber wheel lifting platform 11 moves the first rubber wheel 8 above the inner arc guide rail 4 and comes into contact with the magnetic material, the limiting frame 18 will limit the magnetic material to prevent it from shifting. Since the magnetic material wiring is prone to warping, the limiting frame 18 can prevent this phenomenon.

[0038] The elastic linkage mechanism includes a guide post 32 vertically mounted on the glue-applying lifting platform 11 and slidingly engaged with the glue-applying fixing plate 21. A spring 27 is fitted on the outside of the guide post 32, and the upper and lower ends of the spring 27 are elastically connected to the glue-applying fixing plate 21 and the glue-applying lifting platform 11, respectively. A hydraulic rod (not shown in the figure) is provided on the glue-applying lifting platform 11 and the glue-applying fixing plate 21, and the upper and lower ends of the hydraulic rod are connected to the glue-applying lifting platform 11 and the glue-applying fixing plate 21, respectively. Thus, through the elastic linkage mechanism, when the first glue wheel 8 can contact the outer arc surface of the magnetic material, it is ensured that the first glue wheel 8 always maintains a sufficiently stable bearing force on the magnetic material.

[0039] The lower rubber wheel transmission mechanism includes a lower rubber wheel lifting platform 12 that moves longitudinally on the vertical plate 2. A second rubber wheel 9 is provided on one side of the lower rubber wheel lifting platform 12 and moves longitudinally synchronously with it on the vertical plate 2. The lower rubber wheel lifting platform 12 is equipped with a second transmission shaft 31 that drives the second rubber wheel 9 to rotate on the vertical plate 2. The first rubber wheel 8 and the second rubber wheel 9 are parallel to each other. The lower rubber wheel lifting platform 12 is connected to a first transmission screw 22, thereby causing the lower rubber wheel lifting platform 12, along with the second rubber wheel 9, to move longitudinally on the vertical plate 2 until it contacts the magnetic material on the inner arc guide rail 4 and presses the magnetic material onto the inner arc guide rail 4. Simultaneously, the second transmission shaft 31 drives the second rubber wheel 8 to rotate on the vertical plate 2. The two rubber wheels 9 rotate and move relative to the first rubber wheel 8, thereby clamping the magnetic material on the inner arc guide rail 4 and pushing it forward. The second transmission shaft 31 is connected to the drive shaft 13 for driving. The second transmission shaft 31 is provided with a fourth bevel gear 30 that rotates coaxially with it, and the lower end of the drive shaft 13 is also provided with a second bevel gear 25 that rotates coaxially with it and meshes with the fourth bevel gear 30. When the second motor 17 drives the drive shaft 13 to rotate, it also drives the second bevel gear 25 to rotate. Then, through the meshing between the second bevel gear 25 and the fourth bevel gear 30, the second transmission shaft 31 is driven to rotate along with the second rubber wheel 8.

[0040] The inner arc guide rail 4 is provided with a through hole 33 that allows the lower rubber wheel transmission mechanism to contact the inner arc surface of the magnetic material. When the lower rubber wheel lifting platform 12, together with the second rubber wheel 9, moves to the bottom of the inner arc guide rail 4 and the magnetic material moves above the through hole 33, the outer edge of the second rubber wheel 9 is made to be flush with the surface of the inner arc guide rail 4 through the through hole 33, thereby contacting the inner arc surface of the magnetic material placed on the inner arc guide rail 4. This allows the first rubber wheel 8 and the second rubber wheel 9, which are located above and below the inner arc guide rail 4, to rotate in opposite directions and apply a forward conveying force to the magnetic material located above the through hole 33.

[0041] A transmission belt 5 for transporting magnetic materials is horizontally arranged on one side of the upright plate 1. A pressure wheel 6 is provided on one side of the surface of the transmission belt 5 to limit the magnetic materials during the transmission process and prevent them from shifting. The transmission belt 5 is connected to the inner arc guide rail 4, so that the magnetic materials on the transmission belt 5 can move one after another onto the inner arc guide rail 4. A grinding mechanism is provided on the other side of the upright plate 1, which is raised and lowered at the upper end of its front side and grinds the magnetic materials. The grinding mechanism is horizontally located above the inner arc guide rail 4 and on one side of the upper rubber wheel transmission mechanism. The grinding mechanism can grind the magnetic materials pushed in by the upper rubber wheel transmission mechanism and the lower rubber wheel transmission mechanism through rotation and compression. The upright plate 2 is also provided with a crossbeam support frame 3 for supporting the inner arc guide rail 4.

[0042] The grinding mechanism includes a movable stage (not shown in the figure) movably mounted on the vertical plate 2, a cylinder 14 that drives the movable stage to move up and down on the vertical plate 2, an outer arc grinding wheel 7 rotatably mounted on one side of the movable stage, a first motor 5 for driving the outer arc grinding wheel 7 to rotate, and a pull rod 16 for supporting the first motor 15. When the movable stage is driven to rise and fall on the vertical plate 2 by the cylinder 14, the movable stage and the outer arc grinding wheel 7 move together to the top of the magnetic material placed on the inner arc guide rail 4, and the first motor 5 drives the outer arc grinding wheel 7 to rotate on one side of the movable stage and grind the outer arc surface of the magnetic material.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
