Specifically, driving piece 1 and fixed plate 2 are all fixed on backup pad 25 and backup pad 25 is in between driving piece 1 and the fixed plate 2, and backup pad 25 is used for the fixed and the installation of whole shutoff mechanism, promotes piece 3 to connect the output at driving piece 1, and fixed plate 2 cover is established in the outside of promoting piece 3, and movable plate 4 activity sets up in fixed plate 2 one side of keeping away from driving piece 1, and promotes piece 3 to insert and establish in movable plate 4, and end cap 5 one end articulates on movable plate 4 and supports with the front end activity of promoting piece 3 and lean on.
In the initial state, as shown in fig. 2, the axial direction of the plug 5 is perpendicular to the output direction of the driving piece 1, the plug 5 is folded and stored on the plugging mechanism, when the device works, the driving piece 1 drives the pushing block 3 to move, when the pushing block 3 moves, the plug 5 is pushed to rotate relative to the moving plate 4 first, after the pushing block 3 moves to a preset position (the position where the plug 5 rotates to be shown in fig. 1 is a reference for the pushing block 3 to move to the preset position), the pushing block 3 drives the moving plate 4 to move towards a direction away from the fixed plate 2, so that the plug 5 abuts against a side wall of a workpiece to be plugged, the driving piece 1 drives the plug 5 to move after rotating in the vertical direction in a working mode, the working space in the vertical direction can be utilized, the plug 5 can be moved for a smaller distance in the horizontal direction, the displacement of the horizontal direction of the driving piece 1 is reduced, and preferably, the driving piece 1 can be a motor, an air cylinder, an electromagnet or other power mechanism.
The following describes the specific structure of the plugging mechanism by two examples:
example 1
The pushing block 3 is provided with a first chute 6 near one side of the driving piece 1, a first fixed block 7 is inserted on the moving plate 4, the first chute 6 is sleeved on the outer side wall of the first fixed block 7, and a first elastic piece 8 is arranged between the side wall of the first chute 6 and the first fixed block 7.
When the driving member 1 drives the pushing block 3 to move from right to left as shown in fig. 3, the pushing block 3 firstly pushes the plug 5 to rotate, the moving plate 4 does not start to move while the plug 5 rotates, and the first chute 6 moves together with the pushing block 3, so that when the pushing block 3 moves, the first elastic member 8 is in a compressed state, after the plug 5 rotates to a preset position, the first elastic member 8 cannot compress again, and starts to push the first fixed block 7 to move together with the pushing block 3, when the first fixed block 7 moves, the moving plate 4 starts to drive the moving plate 4 to move, and when the moving plate 4 moves, the plug 5 can be driven to move from right to left as shown in fig. 3, so that the plug 5 starts to be attached to a workpiece after rotating to the preset position.
Further, one side of the fixed plate 2, which is close to the movable plate 4, is connected with a guide post 9, one end, away from the movable plate 4, of the guide post 9 is provided with a pushing part 10, the outer side wall of the guide post 9 is sleeved with a second elastic piece 11, two ends of the second elastic piece 11 are respectively propped against between the pushing part 10 and the movable plate 4, and the elastic coefficient of the second elastic piece 11 is larger than that of the first elastic piece 8.
When the driving member 1 pushes the pushing block 3 to move and compress the first elastic member 8, since the elastic coefficient of the second elastic member 11 is larger than that of the first elastic member 8, the moving plate 4 will not start to move when the first elastic member 8 starts to compress, and after the first elastic member 8 is compressed to a certain extent (the plug 5 rotates to a preset position), the first fixing block 7 starts to drive the moving plate 4 to move and the second elastic member 11 starts to compress.
Preferably, the driving member 1 drives the pushing block 3 to move and then drives the moving plate 4 to move through the first fixed block 7 without providing the second elastic member 11, which may be realized through friction force between the guide post 9 and the moving plate 4, that is, friction force between the guide post 9 and the moving plate 4 is increased through a concave-convex structure arranged between the guide post 9 and the moving plate 4 or a friction block is increased, so that before the pushing block 3 moves to the position that the plug 5 rotates to a preset position, the pushing block 3 moves and the moving plate 4 does not move because friction force between the pushing block 3 and the guide post 9 is greater than the thrust of the first spring 8 on the moving plate 4, and after the plug 5 rotates to the preset position, the elastic force of the first elastic member 8 compressed to itself is greater than the friction force between the moving plate 4 and the guide post 9, thereby starting to push the moving plate 4 to move relative to the guide post 9.
Further, one end of the pushing block 3 far away from the driving piece 1 is provided with a first pushing rod 15 and a second pushing rod 16 at intervals, the length of the first pushing rod 15 is smaller than that of the second pushing rod 16, the first pushing rod 15 is movably abutted against the side wall of the plug 5, and the side wall of the second pushing rod 16 is movably abutted against the side wall of the plug 5.
Because the plug 5 is hinged on the movable plate 4, and the first pushing rod 15 abuts against the side wall of the plug 5, when the pushing block 3 moves, the first pushing rod 15 pushes the plug 5 to rotate, so that the plug 5 can rotate to a preset position, the side wall of the second pushing rod 16 abuts against the side wall of the plug 5 in a movable manner, the plug 5 can be limited to rotate again after the plug 5 rotates to the preset position, the direction of the plug 5 after the plug 5 rotates to the preset position is guaranteed, and the plug 5 is tightly abutted against a workpiece.
Further, a connecting rod 17 is inserted at one side of the moving plate 4 far away from the driving piece 1, a through hole is formed in the end portion of the plug 5, the through hole is sleeved on the outer side wall of the connecting rod 17, and the connecting rod 17 and the through hole are used for realizing hinging between the plug 5 and the moving plate 4.
Further, the moving plate 4 is provided with a counter bore 18 and a mounting hole 19 communicated with the counter bore 18, the end part of the connecting rod 17 is provided with a connecting groove 20, the end part of the connecting rod 17 is sleeved with a torsion spring 21, a main body part 22 of the torsion spring 21 is positioned in the counter bore 18, and two pins 23 of the torsion spring 21 are respectively positioned in the mounting hole 19 and the connecting groove 20.
In the process that the driving piece 1 pushes the plug 5 to rotate through the pushing block 3, the distance between the two pins 23 of the torsion spring 21 is slowly increased, so that the torsion spring 21 is slowly in a stretching state, after the pushing block 3 is reset, the torsion spring 21 is restored to an initial state, the distance between the two pins 23 is shortened, and when the distance between the pins 23 is shortened, the plug 5 is driven to rotate from the state shown in fig. 2 to the state shown in fig. 1.
Further, an abutment sleeve 24 is inserted on the moving plate 4, and the guide post 9 passes through the abutment sleeve 24 and is connected to the moving plate 4, and an end of the abutment sleeve 24 abuts against an end of the second elastic member 11. The abutment sleeve 24 serves to avoid direct friction between the moving plate 4 and the guide post 9, thereby preventing wear of the moving plate 4 and increasing the service life of the moving plate 4.
Preferably, the first elastic member 8 and/or the second elastic member 11 may be a spring or a rubber product.
Example two
The pushing block 3 is provided with a second chute 12 near one side of the driving piece 1, a second fixed block 13 is inserted on the moving plate 4, at least one side of the side wall of the second chute 12 extends towards the center position of the second chute 12 to form a blocking block 14, the second chute 12 is sleeved on the outer side wall of the second fixed block 13, and the blocking block 14 is movably abutted against the second fixed block 13.
In this scheme, when the driving piece 1 pushes the pushing block 3 to move, the pushing block 3 moves and the moving plate 4 does not move, and in the process of moving the pushing block 3, the side wall of the second fixed block 13 slowly approaches to the side wall of the blocking block 14, after the second fixed block 13 is attached to the blocking block 14, the moving plate 4 is driven to move by the second fixed block 13 when the pushing block 3 moves, and this scheme can also realize that when the driving piece 1 drives the pushing block 3 to move, the pushing block 3 is firstly made to move and the moving plate 4 is not moved, and after the pushing block 3 pushes the plug 5 to rotate to a preset position, the pushing block 3 starts to drive the moving plate 4 to move.
In this embodiment, an elastic member may be disposed between the guide post 9 and the moving plate 4, or the elastic member may not be disposed, and the structure of other parts of the plugging mechanism is the same as that of the first embodiment, which is not repeated here.
