Referring to fig. 1,2 and 3, an embodiment of the present invention provides a quick-change interface for providing thrust by a rotary electromagnet, which includes a driving portion 1 and a driven portion 2 that is in locking connection with the driving portion 1, wherein a locking surface of the driving portion 1 is provided with an annular column 11 for embedding the driven portion 2, the annular column 11 is provided with a guide channel 111 that communicates an inner side wall and an outer side wall thereof, a guide hole 112 that is positioned on the outer side wall of the annular column 11 is provided in the guide channel 111, a guide member 113 is provided in the guide channel 111, a steel ball 114 that is connected with the guide member 113 is provided in the guide hole 112, an electromagnet 12 that can be positively rotated is provided in the driving portion 1, a rotary cam 13 that is connected with the electromagnet 12 is provided in the annular column 11, and the guide member 113 can be pushed and the steel ball 114 is pressed toward the outer side of the annular column 11 when the rotary cam 13 is positively rotated; an annular locking block 21 (refer to fig. 5) is disposed in the passive part 2, and the steel balls 114 can be locked into the annular locking block 21 when moving along the outer direction of the annular column 11, so as to form a locking structure of the active part 1 and the passive part 2.
Referring to fig. 3 and fig. 4, in this embodiment, the active portion 1 and the passive portion 2 are both cylindrical, and after the annular post 11 is embedded into the active portion 1, the active portion 1 and the passive portion 2 can be initially inserted and then locked; the specific locking process comprises the following steps: after the driving part 1 and the driven part 2 are inserted, forward current is introduced to drive the electromagnet 12 to rotate forward, the electromagnet 12 drives the rotary cam 13 to rotate synchronously when transmitting forward, the rotary cam 13 can push the guide piece 113 to move in the guide channel 111 towards the outer side direction of the annular column 11, and the guide piece 113 can drive the steel ball 114 to move in the guide hole 112 towards the outer side direction of the annular column 11 and be clamped into the annular locking piece 21 when moving, so that a locking structure of the driving part 1 and the driven part 2 is formed, and locking force of the driving part 1 and the driven part 2 in the axial direction is provided.
Further, after the reverse current is applied to the electromagnet 12, the electromagnet 12 can be reversed to drive the rotary cam 13 to synchronously reverse, and the rotary cam 13 can release the pushing force to the guide member 113 after synchronously reversing, so that the steel ball 114 loses the clamping force clamped on the annular locking piece 21, and the locking force between the driving part 1 and the driven part 2 is released and the separation can be performed.
It should be noted that, the diameter of the inside and outside of the guide hole 112 is smaller than the diameter of the steel ball 114, and when the steel ball 114 moves in the guide hole 112 toward the inside and outside of the annular column 11, the spherical surface of the steel ball 114 can be extruded to the inside and outside of the annular column 11, but the steel ball 114 is always located in the guide hole 112 and cannot fall off.
In an embodiment, the locking surface of the active part 1 is provided with a positioning ball 14, and the locking surface of the passive part 2 is provided with a positioning part 22 for positioning the positioning ball 14.
In this embodiment, in the process of inserting the active portion 1 and the passive portion 2, the positioning ball 14 and the positioning portion 22 may be used to perform accurate positioning, so that the locking surfaces of the active portion 1 and the passive portion 2 are primarily attached to each other for subsequent locking.
In an embodiment, an upper PIN 15 exposed from the locking surface is disposed in the active portion 1, a lower PIN 23 connected to the upper PIN 15 is disposed in the passive portion 2, and the upper PIN 15 and the lower PIN 23 are energized to generate a current sent to the electromagnet 12.
In this embodiment, after the active portion 1 and the passive portion 2 are inserted and accurately positioned, the upper PIN 15 and the lower PIN 23 are electrically connected, and at this time, the electromagnet 12 can be rotated forward by applying a forward current, that is, after applying a forward current, the electromagnet 12 can be driven to drive the rotating cam 13 to rotate synchronously forward and lock the active portion 1 and the passive portion 2, and after applying a reverse current, the electromagnet 12 can be driven to drive the rotating cam 13 to rotate synchronously reversely and separate the active portion 1 and the passive portion 2.
Referring to fig. 5 and 6, in an embodiment, the electromagnet 12 is rotatably connected to the top of the driving part 1, the rotating cam 13 is disposed at the bottom of the driving part 1, and a connecting rod 121 passing through the rotating cam 13 is disposed at the bottom of the electromagnet 12; the side wall of the rotary cam 13 is provided with an arc-shaped top block 131, and when the rotary cam 13 rotates forward, the arc-shaped top block 131 can be driven to push the guide piece 113 to the outer side direction of the annular column 11, and the steel balls 114 are linked to be clamped into the annular locking block 21.
In this embodiment, the electromagnet 12 may be circular, square, or other shapes, and the connecting rod 121 may be integrally or separately disposed with the electromagnet 12, where the upper end of the connecting rod 121 is connected to the bottom center of the electromagnet 12, and the lower end of the connecting rod 121 passes through the middle of the rotating cam 13; when the electromagnet 12 is driven to rotate in forward and reverse directions, the connecting rod 121 can transmit torque force to the rotating cam 13, so as to drive the rotating cam 13 to rotate in forward and reverse directions synchronously.
With reference to fig. 3 and fig. 4, further, an arc-shaped top block 131 is disposed on the side wall of the rotary cam 13, when the rotary cam 13 rotates forward, the arc-shaped top block 131 is driven to rotate forward in the circumferential direction and to abut against the guide member 113, and the guide member 113 is pushed in the continuous forward rotation process, so that the guide member 113 moves in the guide channel 111 towards the outer side direction of the annular post 11, and then the steel balls 114 are driven to move in the guide hole 112 towards the outer side direction of the annular post 11 and are blocked into the annular locking block 21.
Conversely, when the rotating cam 13 rotates reversely, the arc-shaped top block 131 is driven to rotate reversely in the circumferential direction and release the pushing force to the guide member 113, and is separated from the guide member 113 in the continuous reverse rotation process, so that the guide member 113 loses the pushing force to the steel ball 114, and the steel ball 114 loses the clamping force to the annular locking block 21.
In an embodiment, the guide channel 111 is provided with a plurality of arc-shaped top blocks 131 corresponding to the guide channel 111, and the arc-shaped top blocks 131 are formed with corresponding notches 132.
In this embodiment, 3 guide channels 111 may be provided and uniformly distributed along the annular direction of the annular column 11, and each guide channel 111 is provided with a guide member 113 and a steel ball 114, so that 3 clamping points clamped on the annular locking block 21 may be formed in the annular direction, and the locking force of the driving part 1 and the driven part 2 may be improved; correspondingly, 3 arc-shaped top blocks 131 are also arranged on the side wall of the rotary cam 13, and each arc-shaped top block 131 correspondingly pushes the guide piece 113 and the steel ball 114 in one guide channel 111.
Further, a corresponding notch 132 is formed between adjacent arc-shaped top blocks 131, when the arc-shaped top blocks 131 are driven to rotate forward, the arc-shaped top blocks 131 push the guide member 113 to move, and it can be understood that when the arc-shaped top blocks 131 are driven to rotate reversely, the arc-shaped top blocks 131 are separated from the guide member 113, and after separation, the notch 132 corresponds to the position of the guide member 113, namely the pushing force pushing the guide member 113 is lost; based on the structural principle, the steel balls 114 are controlled to be clamped on the annular locking block 21 or the clamping force on the annular locking block 21 is controlled to be released.
In an embodiment, the profile track from the notch 132 to the adjacent arc-shaped top block 131 is arc-shaped.
In this embodiment, in the process of driving the rotating cam 13 to rotate forward and backward, the arc-shaped top block 131 and the notch 132 rotate along with the rotation, and the notch 132 abuts against or separates from the guide member 113 in the rotation process, so that the profile track from the notch 132 to the adjacent arc-shaped top block 131 is set to be arc-shaped, and the stability of the structure during movement can be improved in the abutting against or separating from the guide member 113.
Referring to fig. 7 and 8, in an embodiment, the guide member 113 includes a guide rod 1131, a pulley 1132 disposed at one end of the guide rod 1131, and a spring 1133 sleeved on the guide rod 1131, wherein the other end of the guide rod 1131 is connected to the steel ball 114, one end of the spring 1133 abuts against one end of the guide rod 1131, and the other end of the spring 1133 abuts against the guide hole 112.
In this embodiment, the pulley 1132 is disposed at one end of the guiding rod 1131 and is located at the inner side of the annular column 11, when the rotating cam 13 does not push the guiding element 113, the pulley 1132 is corresponding to the notch 132, and when the rotating cam 13 rotates forward, the arc-shaped top block 131 can rotate forward and abut against the pulley 1132 and push the steel ball 114 in linkage with the guiding rod 1131, and by disposing the pulley 1132, the friction force with the arc-shaped top block 131 in the circumferential direction can be reduced, so that the arc-shaped top block 131 can push the guiding element 113 more easily.
Further, in the process that the arc-shaped top block 131 pushes the guide member 113, the guide member 113 may compress the spring 1133 when moving outwards, so that when the clamping force of the steel ball 114 to the annular locking piece 21 is released, the spring 1133 returns the spring force to make the guide member 113 move towards the inner side of the annular column 11 and drive the steel ball 114 to move back into the guide hole 112, so that the steel ball 114 is separated from the annular locking piece 21, and the driving part 1 and the driven part 2 can be separated.
Referring to fig. 5 and 6, in an embodiment, an angle limiting rod 133 is disposed at the bottom of the rotating cam 13, and a limiting groove for limiting the rotation angle of the angle limiting rod 133 is disposed at the bottom of the annular column 11.
In this embodiment, in the process of controlling the locking or separating of the driving part 1 and the driven part 2, only the rotating cam 13 is controlled to rotate forward and backward by a certain angle, so that the arc-shaped top block 131 and the adjacent notch 132 thereof rotate; the angle limiting lever 133 and the limiting groove are provided to control the rotation angle of the rotating cam 13, thereby preventing malfunction of the device caused by excessive rotation.
Referring to fig. 7 and 8, in an embodiment, a locking groove 211 for the steel ball 114 to be snapped in is provided on the inner side of the annular locking block 21.
In this embodiment, the locking groove 211 is a locking opening that is inclined toward the inner side, and when the steel ball 114 is pressed along the outer side direction of the annular column 11, the steel ball can abut against the locking groove 211 and is completely clamped into the locking groove 211 in the continuous pressing process, so as to generate a locking force between the driving portion 1 and the driven portion 2.
In an embodiment, the positioning balls 14 are 3 and uniformly distributed, the positioning portions 22 are correspondingly provided with 3 positioning portions, and each positioning portion 22 is composed of two arc-shaped positioning members 221 arranged at intervals.
In this embodiment, the number of the positioning balls 14 may be 3 and are uniformly distributed on the locking surface of the active portion 1, and correspondingly, the number of the arc-shaped positioning members 221 is 6 and are correspondingly distributed in the locking surface of the passive portion 2 in pairs; after the driving part 1 and the driven part 2 perform coarse positioning preliminarily, the positioning ball 14 is correspondingly arranged between two arc positioning pieces 221 arranged at intervals, and the circumferential direction of the positioning pieces can be limited, so that the advantage of accurate positioning through the positioning ball 14 and the arc positioning pieces 221 is achieved.
