Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "provided", "sleeved/connected", "connected", and the like are to be understood in a broad sense, such as "connected", which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1-3, an adjustable electromagnetic force ejection pin comprises a base 1, a mounting groove 2 is formed in the top of the base 1, an electromagnetic coil 3 is mounted in the mounting groove 2, an ejection pin 4 is arranged on the base 1, the left end of the ejection pin 4 sequentially penetrates through the base 1 and the electromagnetic coil 3 and extends to the left side of the base 1, a positioning shaft pin 5 is fixedly connected to the left end of the ejection pin 4, the left end of the positioning shaft pin 5 is rotatably connected with a positioning bearing 6, two coil pin wiring 7 are arranged on the right side of the electromagnetic coil 3, and two mounting holes 8 are formed in the front and at the back of the bottom of the base 1.
The working principle is as follows: the utility model discloses connect 7 with solenoid 3 circular telegrams through two coil pins during the use to adjust the pre-pressure through the adjustment electric current size, thereby realize the effort according to load condition automatically regulated control bullet knock pin location, if change solenoid 3's voltage polarity can change 4 directions of motion of positioning pin axle simultaneously, can realize the bi-directional location.
As shown in fig. 2, in this case, the moving member is in an unset state, the moving member slides in the direction indicated by the arrow, at this time, the electromagnetic coil 3 is energized to eject the pin to apply a certain pressure to the moving member, the controller calculates a control current according to the inertia of the moving member, so as to control the magnitude of the pre-pressure, and the moving member slides forward until reaching the position of the V-shaped notch;
as shown in fig. 3, in this case, the moving member is positioned accurately due to the positioning bearing 5 at the top end of the ejection pin matching with the V-shaped notch of the moving member.
The above description is only the preferred embodiment of the present invention; the scope of the present invention is not limited thereto. Any person skilled in the art should also be able to cover the technical scope of the present invention by replacing or changing the technical solution and the improvement concept of the present invention with equivalents and modifications within the technical scope of the present invention.
