Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of machining, more specifically, the utility model relates to an arc chamfering device of tile-shaped magnet. BACKGROUND

[0002] In the prior art, when tile-shaped magnets are machined on the inner and outer arc surfaces, the inner and outer arc end surfaces often need to be chamfered to meet the machining requirements. The chamfering sizes required by tile-shaped magnets with different requirements are not the same. The traditional pure manual grinding method obviously cannot meet the requirements of high efficiency and high precision. Therefore, various grinding machines and equipment for chamfering the inner and outer arc end surfaces of tile-shaped magnets have appeared on the market, which have the advantages of high efficiency, high precision and high product qualification rate.

[0003] The existing device usually adopts a cam mechanism and a return spring to realize the reciprocating movement of the pushing mechanism. However, the chamfering device usually places the motor at the bottom of the rack. The ground of the factory workshop often forms water accumulation due to equipment cleaning or a humid environment. The wiring port and the heat dissipation hole of the cam reducer are directly exposed to the humid environment, which is prone to moisture and water ingress, causing damage to the cam reducer. This not only increases the equipment maintenance cost and downtime loss, but also affects the production continuity. For example, patent application No. CN202422731744.2 discloses an arc chamfering device for tile-shaped magnets. In this device, the cam reducer is placed at the bottom of the rack. This causes water accumulation on the ground of the factory workshop due to equipment cleaning or a humid environment. The cam reducer needs to be cooled on the surface or bottom, so heat dissipation holes need to be opened on the surface or bottom. This causes water vapor to enter the rack through the heat dissipation holes, causing damage to the cam reducer and increasing equipment maintenance costs while affecting work. SUMMARY

[0031] As Figure 1 - Figure 8The arc chamfering device of the tile-shaped magnet is shown, which comprises a rack 1, a feeding mechanism 2, a poking mechanism 3, a pushing mechanism 4 and a chamfering mechanism 5 arranged on the rack 1, wherein the pushing mechanism 4 comprises a cam speed reducer 41 arranged on the top of the rack 1, a connecting plate 42 arranged on the end of the rotating shaft of the cam speed reducer 41, a special connecting rod 43 hinged to the end of the connecting plate 42 away from the rotating shaft, a mounting plate 44 arranged in the interior of the rack 1, a push plate 45 slidingly arranged on the mounting plate 44, a pushing rod 47 arranged on the push plate 45 through a adapter I 46, a transmission wheel I 48 arranged on the extended end surface of the side of the push plate 45 away from the pushing rod 47, and a waist-shaped slot I 431 arranged on the end of the special connecting rod 43 away from the rotating shaft for the transmission wheel I 48 to extend into, wherein the opening direction of the waist-shaped slot I is matched with the movement direction of the special connecting rod.

[0032] Wherein, the push plate 45 and the side wall of the rack 1 are provided with a reset elastic element I 49.

[0033] Working principle:

[0034] In actual application, the tile-shaped magnet is transmitted to the end of the feeding mechanism 2, and is pushed from the end of the feeding mechanism 2 to the starting end of the pushing mechanism 4 by the poking mechanism 3, and is sent into the feeding end of the chamfering mechanism 5 under the action of the pushing mechanism 4, and the arc surface of the tile-shaped magnet is chamfered under the polishing of the chamfering mechanism 5; wherein the rotating shaft of the cam speed reducer 41 rotates to drive the connecting plate 42 to rotate in space, and then the one end of the special connecting rod 43 rotates around the rotating shaft of the cam speed reducer 41, and the other end of the special connecting rod 43 drives the transmission wheel I 48 on the push plate 45 through the waist-shaped slot I 431 to make the push plate 45 slide on the mounting plate 44, and then the pushing rod 47 moves backward in space through the adapter I 46, and reciprocates in space under the cooperation of the reset elastic element I 49 to realize the continuous pushing of the tile-shaped magnet, the opening direction of the waist-shaped slot I 431 is matched with the movement direction of the special connecting rod 43 to smoothly convert the circular track movement of the special connecting rod 43 into the linear movement of the push plate 45 along the mounting plate 44, and meanwhile, the rigid interference between the special connecting rod 43 and the transmission wheel I 48 is avoided. Meanwhile, the cam speed reducer 41 is placed on the top of the rack 1 in the device to avoid the damage of the cam speed reducer 41 caused by the water area or the environmental humidity, prolong the service life of the equipment, reduce the maintenance cost of the equipment, and ensure the continuity of the operation.

[0035] In the above technical solution, the poking mechanism 3 comprises: a poking rod 35, a sliding plate 31 arranged in the rack 1 and located at one side of the cam speed reducer 41, a sliding block 32 slidingly arranged on the sliding plate 31, a cam 33 coaxially arranged with the connecting plate 42 and drivingly connected with the cam speed reducer 41, a switching piece II 34 arranged on the poking rod 35 and drivingly connected with the sliding block 32, the switching piece II 34 slidingly arranged on the side wall of the rack 1, a transmission wheel II 36 arranged on one side of the sliding block 32 and matched with the cam, and a transmission wheel III 37 arranged on the other side of the sliding block 32 and matched with the switching piece II 34.

[0036] The end of the switching piece II 34 close to the sliding block 32 is provided with a connecting piece 38, the connecting piece 38 has a wedge surface in contact with the transmission wheel III 37, a reset elastic element II 39 is arranged between the switching piece II 34 and the side wall of the rack 1, so that the transmission wheel II 36 and the transmission wheel III 37 are always in contact with the cam and the connecting piece 38 when the cam rotates in space, and the switching piece II 34 and the sliding block 32 are perpendicular to each other in space. When the cam rotates synchronously with the cam speed reducer 41, the cam drives the sliding block 32 to slide along the sliding plate 31 through the cooperation with the transmission wheel II 36, and the transmission wheel III 37 on the other side of the sliding block 32 is in contact with the wedge surface of the connecting piece 38 on the switching piece II 34. Since the switching piece II 34 and the sliding block 32 are perpendicular to each other in space, the sliding of the sliding block 32 is converted into the sliding of the switching piece II 34 along the side wall of the rack 1 through the guiding action of the wedge surface, and then drives the poking rod 35 to move outward, at this time, the reset elastic element II 39 is in a stretched state, and when the cam rotates to a non-acting position, the pushing force of the cam on the transmission wheel II 36 disappears, the reset elastic element II 39 releases the elastic potential energy and drives the poking rod 35 to move inward, thereby realizing the transmission of the material of the tile-shaped magnet from the end of the feeding mechanism 2 to the starting end of the poking rod 35, and the connecting piece 38 retreats and drives the sliding block 32 to return to the initial position. Through the cooperation of the "cam driving and elastic element resetting", the poking rod 35 can realize stable reciprocating motion, and in this process, the device realizes the actions of poking and pushing through one cam speed reducer 41, and the existing device needs at least two cam speed reducers 41 to complete the actions of poking and pushing, so that the device is more simple and saves cost.

[0037] In the above technical solution, the surface of the pushing plate on the same side as the transmission wheel I is provided with a connecting rod extending into the waist-shaped groove I, and the connecting rod limits the position of the special-shaped connecting rod through a limiting piece after penetrating through the waist-shaped groove I.
