Referring to fig. 1 and fig. 2, the pressing device 100 includes a fixing base 10, a pressing rod 20, a first magnet 30 and a second magnet 40.
One end of the pressure lever 20 is rotatably connected with the fixed seat 10. The pressing rod 20 further includes at least one pressing portion 21, and the pressing portion 21 is disposed on the pressing rod 20 for pressing a workpiece (not shown).
The first magnet 30 is disposed on a side of the fixing base 10 facing the pressing rod 20, and the second magnet 40 is disposed on a side of the pressing rod 20 facing the fixing base 10. Like poles of the second magnet 40 and the first magnet 30 repel each other.
The pressing portion 21 is driven to rotate towards the direction approaching the fixed seat 10 by pressing the pressing rod 20, and the pressing portion 21 presses the workpiece. After the pressing is finished, the pressing rod 20 is under the action of the magnetic repulsion force of the first magnet 30 and the second magnet 40, and the pressing rod 20 rotates towards the direction away from the fixed seat 10 and releases the pressing.
Referring to fig. 1 and fig. 2, in an embodiment of the present application, the fixing base 10 further includes a connecting member 11, a first limiting member 12, and a second limiting member 13.
The connecting piece 11 is located the one end of fixing base 10, and the one end that the fixing base 10 was kept away from to connecting piece 11 is provided with pivot 111. The pressure lever 20 is rotatably connected with the connecting member 11 through a rotating shaft 111. The connecting piece 11 increases the distance between the fixed seat 10 and the pressure lever 20, and enlarges the rotation angle of the pressure lever 20, so that the thickness of the pressed workpiece is larger.
The first limiting member 12 is disposed at an end of the fixing base 10 away from the connecting member 11, and one end of the first limiting member 12 away from the fixing base is a clamping groove 121. One end of the pressure rod 20 far away from the connecting piece 11 is arranged in the clamping groove 121. The locking groove 121 is used for stopping the pressing rod 20 to limit the minimum distance between the pressing rod 20 and the fixing seat 10, and is also used for preventing the pressing rod 20 from deviating when rotating.
Specifically, the limiting distance of the first limiting part 12 is preset according to the specific size of the workpiece, so that the pressing rod 20 can just complete pressing and holding the workpiece when being limited by the first limiting part 12, and the pressing and holding are not excessive, thereby avoiding the workpiece from being damaged by pressing.
One end of the second limiting member 13 is connected to one side of the fixing base 10, and the other end is located outside the rotation direction of the pressing rod 20 away from the fixing base 10. The second limiting member 13 is used for stopping the pressing rod 20 to limit the maximum rotation angle between the pressing rod 20 and the fixing base 10.
Specifically, the limiting distance of the second limiting part 13 is preset, so that the pressing rod 20 can be completely separated from the workpiece when limited by the second limiting part 13, and the pressing is released. And the second limiting member 13 can also prevent the push rod 20 from being out of control due to overlarge magnetic repulsion force, thereby avoiding the risk of accidentally injuring a user or a workpiece.
In the present embodiment, the pressing rod 20 is suspended in the middle of the movable range between the first limiting member 12 and the second limiting member 13 without being affected by external force.
Specifically, the calculation formula of the magnetic repulsion force to which the pressing rod 20 is subjected is:
f (magnetic repulsion force) ═ N (multiple) × ρ (magnet density) × V (magnet volume)/L (magnet pitch)
The multiple N is fixed to 600, and the magnet density rho is 0.0075g/mm3Magnet volume V is 3575mm3The magnet pitch L was 40 mm. From this, it is calculated that the magnetic repulsion is 100.5g when the magnet pitch is 40mm, which is larger than the mass 80g of the pressing rod 20, so that the pressing rod 20 can be suspended in the middle of the movable range between the first limiting member 12 and the second limiting member 13.
As shown in fig. 1, the pressing rod 20 is suspended between the first limiting member 12 and the second limiting member 13, and when the workpiece needs to be pressed, the pressing rod 20 is pressed to rotate the pressing rod 20 along the first direction a; when the pressing state needs to be released, the pressing rod 20 stops being pressed, and the magnetic repulsion force is increased due to the fact that the distance between the magnets is reduced, so that the pressing rod 20 rotates along the second direction B under the action of the magnetic repulsion force, and the pressing state is released.
It is understood that in other embodiments of the present application, the connecting member 11, the first limiting member 12 and the second limiting member 13 may be omitted or replaced by other structures with similar effects.
The pressing rod 20 further comprises a pressing portion 22, and the pressing portion 22 is disposed at an end of the pressing rod 20 away from the connecting member 11. The pressing portion 22 is disposed at a position that utilizes the principle of leverage, so that the pressing rod 20 can be pressed more easily.
Specifically, the rotating shaft 111 serves as a fulcrum, and the pressing lever 20 is pressed from the pressing portion 22, that is, the pressed power arm is larger than the resistance arm, thereby saving labor. The user can press the pressing portion 22 manually or can control a dedicated mechanical device to press.
Further, the extending direction of the pressing portion 22 is perpendicular to the extending direction of the pressing lever 20. I.e. the pressing portion 22 together with the pressing rod 20 is substantially L-shaped.
The pressure holding portion 21 further includes a first pressure holding portion 211, a second pressure holding portion 212, and a third pressure holding portion 213.
The first pressing portion 211 is disposed on a side surface of the pressing rod 20 adjacent to the connecting member 11, and is used for pressing a first workpiece (not shown). The second pressing portion 212 is disposed on a side surface of the pressing rod 20 adjacent to the pressing portion 22 for pressing a second workpiece (not shown). The third pressing portion 213 is disposed on a side surface of the pressing portion 22, and is used for pressing a third workpiece (not shown).
Specifically, the first pressing portion 211, the second pressing portion 212, and the third pressing portion 213 are disposed corresponding to positions of the first workpiece, the second workpiece, and the third workpiece. When the pressing lever 20 rotates, the first pressing portion 211, the second pressing portion 212, and the third pressing portion 213 successively contact and press the workpiece.
Specifically, the first workpiece, the second workpiece, and the third workpiece may be mechanical parts such as a buckle, a press block, a spring, and the like, but are not limited thereto.
It is understood that in other embodiments of the present application, the number and the positions of the pressing portions 21 may be set according to the actual situation of the workpiece to be pressed. The pressing portion 22 may be omitted, and the pressing rod 20 may be directly pressed.
In an embodiment, the pressing device 100 further includes a fixing block 50, and the fixing block 50 is disposed on one side of the fixing base 10. The fixing block 50 is used for connecting an external operating device (not shown). When the pressing rod 20 presses the workpiece, an external device is used for performing production work on the workpiece or other components. The external device may be, but is not limited to, a dispensing valve, a brush, a polishing stone, etc.
When the pressing device 100 of the present embodiment works, the pressing portion 22 is pressed to drive the pressing rod 20 to rotate toward the fixing base 10, and the first pressing portion 211, the second pressing portion 212, and the third pressing portion 213 sequentially contact and press the first workpiece, the second workpiece, and the third workpiece. When the pressing part 22 is stopped being pressed when the pressing needs to be released, the pressing rod 20 is rotated in a direction away from the fixing base 10 by the magnetic repulsion force of the first magnet 30 and the second magnet 40, and the pressing part 21 is driven to release the pressing state. Meanwhile, since the first pressing portion 211 and the second pressing portion 212 are perpendicular to the pressing direction of the third pressing portion 213, when a workpiece with a large area needs to be pressed, two-sided positioning can be achieved.
The utility model provides a press and hold device 100 is applied to the industrial production course of working, replaces the manual work to press and holds less machine part, is applicable to and presses simultaneously and holds a plurality of parts, has made things convenient for user's production operation. The device also has the advantages of simple structure, convenient operation and low cost.
