As shown in fig. 1 to 4, the present invention provides a magnetic driving apparatus, which includes a rotating shaft 10, a transmission mechanism 20, a first magnetic mechanism 30, a second magnetic mechanism 40, and a magnetism isolating mechanism 50.
The rotating shaft 10 is rotatably disposed around a central axis thereof, and one end of the transmission mechanism 20 is connected to the rotating shaft 10, and the other end is connected to the first magnetic mechanism 30. When the rotating shaft 10 rotates, the transmission mechanism 20 drives the first magnetic mechanism 30 to move, and the moving direction of the first magnetic mechanism 30 is to move closer to or away from the rotating shaft 10 along the radial direction of the rotating shaft 10.
The second magnetic mechanism 40 is disposed on a side of the first magnetic mechanism 30 away from the rotating shaft 10. That is, during the movement of the first magnetic mechanism 30 to approach or move away from the rotating shaft 10, the first magnetic mechanism 30 moves to approach or move away from the second magnetic mechanism 40 at the same time. The opposite ends of the first magnetic mechanism 30 and the second magnetic mechanism 40 have the same polarity, i.e., the second magnetic mechanism 40 can exert an urging force on the first magnetic mechanism 30.
The magnetism isolating mechanism 50 includes a magnetism isolating sheet 51 disposed movably, and the moving direction is disposed at an angle to the moving direction of the first magnetic mechanism 30. During the movement, the magnetism isolating piece 51 can move between the first magnetic mechanism 30 and the second magnetic mechanism 40, and at the moment, the magnetism isolating piece 51 can isolate the interaction between the first magnetic mechanism 30 and the second magnetic mechanism 40. The magnetism isolating sheet 51 can also move to the side of the first magnetic mechanism 30 and the second magnetic mechanism 40, and the second magnetic mechanism 40 can push the second magnetic mechanism 40.
When the rotating shaft 10 rotates, the first magnetic mechanism 30 is moved close to the second magnetic mechanism 40, and the magnetism isolating sheet 51 is positioned between the first magnetic mechanism 30 and the second magnetic mechanism 40 to isolate the first magnetic mechanism 30 from the second magnetic mechanism 40, so as to prevent the second magnetic mechanism 40 from influencing the movement of the first magnetic mechanism 30.
When the first magnetic mechanism 30 moves to the stroke limit far away from the rotating shaft 10, the first magnetic mechanism 30 moves away from the second magnetic mechanism 40, at this time, the magnetism isolating sheet 51 moves to the side of the first magnetic mechanism 30 and the second magnetic mechanism 40, and the second magnetic mechanism 40 pushes the first magnetic mechanism 30, so that the rotating shaft 10 is driven to rotate, the rotating speed and the torsion of the rotating shaft 10 are increased, and the rotating shaft 10 can drive mechanical equipment with larger weight.
The magnetic shielding sheet 51 is made of a material capable of shielding magnetic force. The material of the magnetism isolating sheet 51 is various in the prior art, for example, the magnetism isolating sheet 51 may be metal, and the invention does not specifically limit the material thereof, and can realize the function of isolating magnetism.
In one embodiment of the present invention, the central axis of the rotating shaft 10 is preferably arranged in the lateral direction, the first magnetic mechanism 30 is arranged above the rotating shaft 10 and the moving direction is preferably in the vertical direction, and the second magnetic mechanism 40 is arranged above the first magnetic mechanism 30.
Preferably, the rotating shaft 10 includes a first shaft member 11 and a second shaft member 12 which are coaxial. The first shaft member 11 and the second shaft member 12 are laterally arranged shaft bodies, and a space is arranged between the first shaft member 11 and the second shaft member 12.
The first shaft member 11 is provided with a first connecting member 13 at an end thereof adjacent to the second shaft member 12, and the second shaft member 12 is provided with a second connecting member 14 at an end thereof adjacent to the first shaft member 11.
The transmission mechanism 20 includes a link 21 disposed between the first link 13 and the second link 14. The first end of the connecting rod 21 is disposed between the first connecting member 13 and the second connecting member 14, the second end of the connecting rod 21 protrudes from the first connecting member 13 and the second connecting member 14 toward the first magnetic mechanism 30, and the second end of the connecting rod 21 is pivotally connected to the first magnetic mechanism 30. The link 21 is pivotally connected to the first link 13 and the second link 14, and the connection position of the link 21 to the first link 13 and the connection position of the link 21 to the second link 14 correspond in the lateral direction.
The connecting positions of the connecting rod 21 and the first connecting piece 13 and the second connecting piece 14 are deviated from the central axis of the rotating shaft 10, namely, the connecting positions of the connecting rod 21 and the first connecting piece 13 and the second connecting piece 14 are not on the same straight line with the central axis of the rotating shaft 10.
When the first shaft member 11 rotates, the second shaft member 12 is rotated by the connecting rod 21, so that the entire rotation shaft 10 is rotated. During the rotation of the rotating shaft 10, the connecting positions of the connecting rod 21, the first connecting piece 13 and the second connecting piece 14 rotate around the central axis of rotation, so that the connecting rod 21 moves, and then the first magnetic mechanism 30 is driven to move up and down longitudinally. When the second magnetic mechanism 40 pushes the first magnetic mechanism 30, the first magnetic mechanism 30 pushes the rotating shaft 10 to rotate through the connecting rod 21, so that the rotating speed of the rotating shaft 10 is increased.
Further, the projection of the first connecting piece 13 and the second connecting piece 14 at the end of the rotating shaft 10 covers the end of the rotating shaft 10, and the connecting position of the connecting rod 13 and the connecting piece 14 is outside the radial direction of the rotating shaft 10. With such an arrangement, it can be ensured that the movement range of the connecting position of the connecting rod 21 and the first connecting piece 13 and the second connecting piece 14 is larger under the condition that the moving distance of the top end of the connecting rod 21 is not changed, so that the acceleration effect on the rotating shaft 10 can be improved.
The invention transmits the rotating shaft 10 and the first magnetic mechanism 30 through the connecting rod 21, has simple structure, and the connecting rod 21 is positioned between the first shaft part 11 and the second shaft part 12 of the rotating shaft 10, so that the rotation of the rotating shaft 10 is not obstructed by the movement of the connecting rod 21.
Obviously, the magnetic driving apparatus of the present invention may have a plurality of first shaft members 11 and second shaft members 12 along the axial direction of the rotating shaft 10, and a connecting rod 21 may be disposed between each first shaft member 11 and second shaft member 12, and a first magnetic mechanism 30 may be connected through the connecting rod 21.
Preferably, in an embodiment of the present invention, the magnetic driving apparatus further includes a case 60. Two ends of the rotating shaft 10 penetrate through two sides of the box body 60, and a bearing sleeved on the rotating shaft 10 is arranged between the rotating shaft 10 and the box body 60. The box 60 serves to support the shaft 10 and to receive a portion of the link 21, thereby preventing dust from falling and improving safety.
Preferably, the magnetism isolating mechanism 50 further includes a mounting frame 52, a support plate 53, and a support column 54.
The mount 52 is mounted on the case 60, and the first magnetic mechanism 30 is disposed in the mount 52. The top of the box 60 is opened with a hole communicating the inside of the mounting bracket 52 and the inside of the box 60, and the connecting rod 21 can pass through the hole and enter the mounting bracket 52.
The magnetism isolating mechanism 50 is provided with a guide portion for guiding the movement of the first magnetic mechanism 30. Specifically, the guiding portion is a guiding hole disposed in the mounting bracket 52, and the extending direction is the same as the moving direction of the first magnetic mechanism 30, and the first magnetic mechanism 30 is disposed in the guiding hole. The guide portion can ensure that the moving direction of the first magnetic mechanism 30 does not deviate, and ensure that the first magnetic mechanism 30 can move up and down.
The second magnetic mechanism 40 is mounted on the magnetism isolating mechanism 50. Specifically, the second magnetic mechanism 40 is mounted on top of the mounting bracket 52 of the magnetism isolating mechanism 50. Therefore, the first magnetic mechanism 30 and the second magnetic mechanism 40 are both mounted on the magnetism isolating mechanism 50, and the mechanism is simplified.
The support plate 53 is disposed between the first magnetic mechanism 30 and the second magnetic mechanism 40, and an opening is provided in the support plate 53 at a position corresponding to the first magnetic mechanism 30 and the second magnetic mechanism 40 to prevent the support plate 53 from obstructing the interaction of the first magnetic mechanism 30 and the second magnetic mechanism 40. The magnetism isolating piece 51 is movably installed on the supporting plate 53, and the supporting plate 53 plays a role of supporting the magnetism isolating piece 51, so that the magnetism isolating piece 51 can move between the first magnetic mechanism 30 and the second magnetic mechanism 40.
The moving direction of the magnetism isolating sheet 51 is perpendicular to the moving direction of the first magnetic mechanism 30, so as to prevent the magnetism isolating sheet 51 from being obstructed by the first magnetic mechanism 30 during the movement process. Since the moving direction of the first magnetic mechanism 30 is the longitudinal direction, the moving direction of the magnetism shielding sheet 51 is the lateral direction.
Further, the support plate 53 is provided with a slide 531 whose length direction is parallel to the moving direction of the magnetism isolating piece 51, and the magnetism isolating piece 51 is mounted on the slide 531. The supporting plate 53 supports the magnetism isolating piece 51 through the slide 531, and the slide 531 can also guide the movement of the magnetism isolating piece 51. In one embodiment of the present invention, the slide 531 is a slide shaft, and the magnetic shielding sheet 51 is fitted around the slide shaft.
The supporting plate 53 may further have a driving member, such as an air cylinder, mounted thereon for driving the magnetism isolating sheet 51 to move. Therefore, in order to ensure the stability of the support plate 53, the support column 54 is disposed below the support plate 53 and supports the support plate 53. The bottom end of the support column 54 is fixedly mounted on the box 60.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
