Description
Technical field
The utility model relates to a kind of locking device, especially the eccentric shaft locking device.
Background technique
Eccentric shaft structure is all arranged on many mechanical mechanisms, be used for the adjusting play or adjust error, as the adjustment in welding equipment guide wheel gap, the adjustment of plane cutting machine perpendicularity etc.Need locked position after eccentric shaft is adjusted, routine has following several mode:
As shown in Figure 1: a kind of employing round nut location.Promptly add fine thread at eccentric shaft 1 rear portion, two round nuts 13 of screwing on are after eccentric shaft 1 is adjusted, round nut 13 is tightened, rely on the frictional force between the round nut 13 and fixed base 2 outsides to fix eccentric shaft 1, or on fixed base 2, stamp screw again, withstand eccentric shaft 1 with bolt.The stress-bearing capability of this structure is less.
As shown in Figure 2: second kind of structure be, fixed base is divided into two-part, and wherein a part is that fixed base A16 uses as guiding; Another part mills out fixed base B17, as clamping usefulness, mixes lock bolt 15 adjustable gaps.After eccentric shaft 1 is adjusted, tighten lock bolt 15, the fixed base B17 that mills out part clamps fixed eccentric shaft.This structure is bigger than round nut coupling mechanism force.
But above two kinds of structures can not prevent that all eccentric shaft is offset.
The model utility content
Goal of the invention of the present utility model is, is provided to adjust eccentric shaft locking or easy and simple to handle, effective and rapid when unclamping, and the eccentric shaft locking device of reliable lock.
The utility model is achieved in that
A kind of eccentric shaft locking device, comprise eccentric shaft and fixed base, described eccentric shaft is installed in the described fixed base, the output terminal of described eccentric shaft and afterbody end place outside the described fixed base, be positioned on the fixed base of described eccentric shaft afterbody end one side and be fixed with fixed gear ring, described eccentric shaft afterbody end is set with the slip gear ring, be provided with dive key between described slip gear ring and the described eccentric shaft, described slip gear ring can be on described eccentric shaft slide relative, in the described slip gear ring outside locking nut is installed, spin together with the silk tooth between described locking nut and the described eccentric shaft, be provided with the mechanism that is connected between described locking nut and the described slip gear ring, described slip gear ring and described fixed gear ring are provided with the engaging tooth that cooperatively interacts.
Further; The described mechanism that is connected is: with the outer rim of the described slip gear ring of described locking nut cooperation place on be provided with annular groove, on the described locking nut Cock screw is installed, described Cock screw one end places described annular groove, and the head of described Cock screw places outside the described locking nut.
Further; The described mechanism that is connected is: with the outer rim of the described slip gear ring of described locking nut cooperation place on be provided with annular groove, described locking nut is provided with locating stud, described locating stud one end places described annular groove, and the other end of described locating stud is positioned at described locking nut.
Further; The described mechanism that is connected is: be fixed with Cock screw on described slip gear ring; The inner edge of described locking nut is provided with the locking nut annular groove, described locking nut radially be provided with the through hole that at least one is not less than described Cock screw diameter, described positioning screwn one end places described annular groove.
Working principle of the present utility model: by the rotational lock nut, the drive mechanism action that is connected, thereby driving the slip gear ring moves, the slip gear ring is separated with the engaging tooth of fixed gear ring, can adjust the eccentric shaft position subsequently, after adjustment is finished, only need tight locking nut, locking nut promotes the slip gear ring and is meshed with fixed gear ring, finishes locking.
The utility model is because of coming transmitting torque by engaging tooth and dive key, so moment is big, and simple in structure, easy and simple to handle, reliable lock.
