Description

Technical Field

[0001] The utility model belongs to the field of mechanical processing, and more specifically, relates to a camber chamfering device for a tile-shaped magnet. Background Art

[0002] In the prior art, when processing the inner and outer arc surfaces of tile-shaped magnets, it is often necessary to chamfer the inner and outer arc end surfaces to meet the processing requirements. The chamfer sizes required for tile-shaped magnets with different requirements are not the same. The traditional pure manual grinding method obviously does not meet the requirements of high efficiency and high precision. Therefore, various grinders and equipment for chamfering the inner and outer arc end surfaces of tile-shaped magnets have appeared on the market. They have the advantages of high efficiency, high precision and high product qualification rate. However, they generally have problems such as complex transmission component design, inaccurate feeding, and poor reliability. Many grinders do not have the function of high-speed operation, so the processing efficiency is also limited.

[0003] Existing devices usually use a cam mechanism and a return spring to realize the reciprocating motion of the pusher mechanism. The change in the cam diameter acts on the pusher mechanism to realize the unidirectional motion of the pusher mechanism. Under the action of the return spring, the pusher mechanism realizes the reciprocating motion of the pusher mechanism in space. In actual work, increasing the cam movement speed can speed up the pushing of the tile-shaped magnet and the chamfering speed. However, the high-speed rotation of the cam will cause it to separate from the connection part of the pusher assembly at the highest and lowest points, thereby forming an impact. This impact will not only increase the wear of the cam and the pusher assembly, but also generate a lot of noise, affecting the overall performance and life of the equipment.

[0004] For example, the grinding device for processing magnetic tile bevels disclosed in application number CN202322022080.8 reciprocates in space through the cam and the reset elastic element of the material pusher assembly. When the processing efficiency of the tile-shaped magnet needs to be improved, the speed of the cam is increased, thereby increasing the pushing speed of the material pusher assembly on the magnetic tile. However, the high-speed rotation of the cam will cause it to separate from the connection part of the material pusher assembly at the highest and lowest points, thereby forming an impact. This impact will not only increase the wear of the cam and the material pusher assembly, but also generate a lot of noise, affecting the overall performance and life of the equipment.

[0022] like Figure 1-Figure 8 The device for chamfering the cambered surface of a tile-shaped magnet shown in the figure comprises: a frame 1, a feeding mechanism 2, a pressing mechanism 3, a pushing mechanism 4 and a chamfering mechanism 6 arranged on the frame 1, and also comprises: a push rod assembly 5 arranged on the frame 1 to enable a push rod 41 of the push mechanism 4 to move unidirectionally in space, and a push plate 54 of the push rod assembly 5 is always in contact with a transmission wheel Ⅰ43 on the push rod 41 of the push rod assembly when reciprocating in space;

[0023] Wherein, a reset elastic element 8 is arranged between the pushing mechanism 4 and the frame 1 .

[0024] Working principle:

[0025] In actual application, the tile-shaped magnet is transmitted to the end of the feeding mechanism 2 through the feeding mechanism 2, and the tile-shaped magnet is pressed from the end of the feeding mechanism 2 into the feeding end of the chamfering mechanism 6 through the reciprocating motion of the pressing rod 31 of the pressing mechanism 3, and is pushed into the chamfering mechanism 6 by the pushing rod 41 of the pushing mechanism 4, and the chamfering of the arc surface of the tile-shaped magnet is completed under the grinding of the chamfering component 61 of the chamfering mechanism 6.

[0026] Among them, the push plate 54 of the push rod assembly 5 is always in contact with the transmission wheel Ⅰ43 on the push rod 41 of the push rod assembly when it reciprocates in space, so that the push rod 41 of the push mechanism 4 moves unidirectionally in space, and at the same time, the reset elastic element 8 (the reset elastic element can be configured as a reset spring) makes the push rod 41 return to the initial position after completing one push and prepare for the next push. The matching mode between the push rod assembly 5 and the push rod 41 is set, and the separation and impact caused by the high-speed rotation of the cam mechanism is reduced compared with the existing cam push rod transmission mode. This not only reduces the wear of equipment components, but also reduces the generation of noise, prolongs the service life of the equipment, and improves the processing speed of the equipment.

[0027] In the above solution, the push rod assembly 5 is configured as any one of an electric push rod component, a pneumatic push rod component or a cam push rod component. With this technical solution, the push rod 41 can be pushed by using an electric push rod, a pneumatic push rod component or a cam push rod component, and during the movement, the push rod 41 will not be greatly impacted, thereby ensuring the rapid and continuous operation of pushing.

[0028] In the above scheme, the cam push rod component includes: a cam reducer 51 arranged inside the frame 1, a connecting plate 52 is transmission-arranged on the rotating shaft of the cam reducer 51, a connecting plate 52 is hingedly connected to one end of the connecting plate 52 away from the rotating shaft, a push plate 54 is hingedly connected to the other end of the connecting rod 53, the middle part of the push plate 54 is hinged to the frame 1, and the end of the push plate 54 away from the connecting rod 53 is transmission-connected to the transmission wheel Ⅰ43 on the pushing mechanism 4. By adopting this technical solution, the movement of the cam reducer 51 drives the rotation of the connecting plate 52. The connecting plate 52 is hinged with a connecting rod 53 at one end away from the rotating shaft. One end of the connecting rod 53 makes a circular motion around the rotating shaft, and the other end is hinged with a push plate 54, and the middle part of the push plate 54 is hinged to the frame 1. The two ends of the push plate 54 make circular motion around the middle part of the push plate 54. While the push plate 54 makes a circular motion at one end away from the connecting rod 53, it is connected to the transmission wheel Ⅰ43 on the pushing mechanism 4, and with the cooperation of the reset elastic element, the push plate 54 always maintains a contact state with the transmission wheel Ⅰ43. Under the push of the push plate 54, the transmission wheel Ⅰ43 drives the pushing rod 41 of the pushing mechanism 4 to move unidirectionally in space, and with the cooperation of the reset elastic element, the pushing rod 41 of the pushing mechanism 4 realizes reciprocating motion in space.

[0029] In the above scheme, the feeding mechanism 2 includes:

[0030] A feeding plate 21 matched with a feeding side of the tile-shaped magnet;

[0031] A conveyor belt 22 spatially matched with the feed plate 21;

[0032] Wherein, two baffles 23 are arranged on the conveyor belt 22 and the feeding plate 21 to form a U-shaped transmission section on the conveyor belt 22 to limit the magnetic tile blanks to be transported.

[0033] The pressing mechanism 3 comprises:

[0034] A pressing rod 31 is arranged above the feeding plate 21, and there is a height difference between the pressing rod 31 and the feeding plate 21, and the pressing rod 31 is located at the end of the feeding plate 21;

[0035] The pressing rod 31 is connected to the adapter plate 34 through the transmission wheel II33 on the adapter II32, and the movement direction of the pressing rod 31 is perpendicular to the transmission direction of the magnetic tile.

[0036] One end of the adapter II 32 is hinged to the frame, and a spring 35 is provided in the middle of the adapter II 32 to abut against the upper surface of the magnetic tile blank on the feeding plate 21, and the contact surface between the adapter plate 34 and the transmission wheel II 33 is provided with at least two downward undulating parts;

[0037] The pushing mechanism 4 comprises:

[0038] A push rod 41 is disposed above the feed plate 21, and has a height difference with the feed plate 21;

[0039] The push rod 41 is connected to the push plate 54 through the transmission wheel Ⅰ43 on the adapter Ⅰ42. The movement direction of the push rod 41 is horizontal to the transmission direction of the magnetic tile, and the push rod 41 and the press rod 31 are perpendicular to each other in space. The reset elastic element 8 is arranged between the adapter Ⅰ42 and the frame 1 to reset the spatial position of the push rod 41, and the adapter Ⅰ42 guides it to the reset position through the matching guide mechanism 9. The press rod is located above the push rod;

[0040] This technical solution is adopted to construct a U-shaped transmission section for limiting the magnetic tile blanks to be transported on the feeding plate 21 and the conveyor belt 22. At the same time, the transmission wheel moves along the upper surface of the adapter plate 34. When the transmission wheel II 33 moves to the highest point on the upper surface of the adapter plate 34, the spring 35 rotates around the hinge point between the adapter II and the frame. The spring is located at the highest point. Under the action of the push rod, a single magnetic tile blank moves forward. When the transmission wheel II moves to the lowest point on the upper surface of the adapter plate, the spring is located at the lowest point and abuts against the upper surface of the subsequent magnetic tile blank to prevent it from affecting the transportation of the previous magnetic tile. When the magnetic tile blank slides through the push rod, the magnetic tile blank is transmitted to the blocking rod at the feed port of the chamfering mechanism. , under the action of the pressing rod, the magnetic tile blank is pressed from the end of the feed plate into the feed port of the chamfering mechanism (because there is a certain height difference between the feed plate and the feed port of the chamfering mechanism, the pressing rod 31 can ensure that a single magnetic tile blank can enter the feed port of the chamfering mechanism. At the same time, when the magnetic tile blank is pressed from the feed plate to the feed port of the chamfering mechanism, the spatial height of the magnetic tile blank is reduced, and the front end of the push rod abuts against the side wall of the magnetic tile blank), and under the cooperation of the push plate 54, the transmission wheel Ⅰ43 and the adapter Ⅰ42, the front end of the push rod 41 is pushed forward along the transmission direction of the magnetic tile, and the push rod 41 pushes the magnetic tile blank into the clamping assembly 62 of the chamfering mechanism 6 to complete the processing of the magnetic tile blank. At the same time, under the action of the reset elastic element 8, the guide mechanism 9 drives the push rod on the adapter Ⅰ42 back to the initial position to prepare for the next cycle of incoming material processing.

[0041] In the above solution, the chamfering mechanism 6 includes:

[0042] Two chamfering components 61 matched with two sides of the tile-shaped magnet, each chamfering component 61 is installed on the frame 1 through a three-degree-of-freedom adjustment mechanism 7;

[0043] A clamping assembly 62 is disposed between the tile-shaped magnet feeding end and the tile-shaped magnet discharging end and is a clamping unit for defining a plurality of adjacent tile-shaped magnets;

[0044] The clamping assembly 62 is arranged on the frame 1, and the multiple tile-shaped magnets on the clamping assembly 62 are lifted in space height through the transmission of the cam transmission unit arranged at the output end of the cam reducer 51, so that the end faces of the tile-shaped magnets at both ends of the clamping assembly 62 correspond to the grinding positions on each chamfering assembly 61. With this technical solution, the magnetic tile blank enters the clamping assembly 62 under the push of the push rod 41, and under the drive of the cam transmission unit (not shown in the figure) of the cam reducer 51, the tile-shaped magnets on the clamping assembly 62 are lifted in space height, and the two sides of the tile-shaped magnet cooperate with the grinding heads of the two chamfering assemblies 61 to achieve the arc chamfering of the tile-shaped magnet. When the tile-shaped magnet is chamfered, the push mechanism 4 pushes the next magnetic tile blank into the clamping assembly 62, and pushes the last tile-shaped magnet that has been polished to the discharge end.

[0045] Among them, the chamfering assembly 61 is adjusted in three directions, X, Y, and Z, by the three-degree-of-freedom adjustment mechanism 7. According to different adjustment amounts, the spatial position of the grinding head can be adjusted in three dimensions, which has better operability and practicality to match the processing of different types of magnetic tiles;

[0046] Each degree of freedom of the three-degree-of-freedom adjustment mechanism 7 is configured to be obtained by adopting a screw rod structure layout;

[0047] When the screw rod method is adopted, each degree of freedom of the three-degree-of-freedom adjustment mechanism 7 includes:

[0048] A fixing member 71, on which two limiting members 72 are arranged opposite to each other, and an inclined portion I 73 matching the adjustment direction of the corresponding degree of freedom is arranged on the opposite surface of each limiting member 72;

[0049] The adjusting plate 74 has inclined parts II 75 matched with the inclined parts I 73 on its two opposite sides. The cooperation of the two inclined parts constitutes a limited sliding design in space to achieve guidance during the sliding process.

[0050] An adjusting screw 78 is arranged on the fixing member 71 through the mounting member 76 and extends into the adjusting plate 74 through the threaded hole 77 on the adjusting plate 74. In practical applications, a matching adjusting handle 79 may be arranged on the adjusting screw 78;

[0051] Among them, the mounting member 76 is provided with a bearing (not shown) at a position cooperating with the adjusting screw 78, and the adjusting plate 74 is provided with a strip-shaped adjusting hole 781 cooperating with the free end of the screw and penetrating the threaded hole 77. The length of the strip-shaped adjusting hole 781 is used to control the adjustment amount of the screw. The function of the bearing is to ensure that the adjusting screw 78 will not interfere with the mounting member 76 when rotating. The structure of the discharge port of the chamfering mechanism is consistent with the structure of the feeding mechanism, and no further elaboration will be made here.

[0052] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
