Description
Technical field
The present invention relates to a kind of part locking device, particularly relate to a kind of running shaft locking device that can rotate the arbitrarily angled quick locking of axial workpiece and release.
Background technique
At present, conventional mainly adopts expansion sleeve structure with the locking mechanism realizing the arbitrarily angled locking of running shaft and release, the joint bolt on expansion sleeve is tightened one by one during locking, pretightening force is applied to the inside and outside ring of expansion sleeve, to eliminate after matching gap and to closely cooperate to produce enough extruding forces with running shaft, under the effect of frictional force, the locking rotating axial workpiece can be realized.When unclamping, need joint bolt be unscrewed, release pretightening force, and by screwing in screw, expansion sleeve inside and outside ring be thrown off.But, the joint bolt number of expansion sleeve is many, cannot ensure when locking one by one that expansion sleeve surface of contact of inside and outside ring in the process of locking is fitted simultaneously, repetitious use easily makes matching surface serious wear, greatly reduces the working life of expansion sleeve.In addition, because joint bolt number is more, this kind of structural type assembling is comparatively loaded down with trivial details, greatly reduces working efficiency.
Summary of the invention
Object of the present invention is just that providing a kind of to solve the problem can will rotate the running shaft locking device of the arbitrarily angled quick locking of axial workpiece and release.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes lock screw, connecting cover, shell, friction top, inner ring, outer shroud, fixed bearing and axle sleeve, described axle sleeve is set on described running shaft, described fixed bearing is provided with endoporus, described fixed bearing is loaded on described axle sleeve by described inner hole sleeve, described inner ring and described outer shroud are all set in described running shaft end circumferentially, the inner side of described outer shroud is by thick gradually thin inclined-plane with the direction of close described axle sleeve, the outside of described inner ring is thin-to-thick inclined-plane with the direction near described axle sleeve, the inclined-plane of described outer shroud and described inner ring contacts with each other, described friction top is arranged at the end face of described running shaft and is connected with described inner ring by screw, one end of described shell is installed on the periphery of described outer shroud and is fixedly connected with described fixed bearing, described connecting cover is fixedly connected with the other end of described shell, described lock screw is also threaded connection with described connecting cover and described friction top through described connecting cover and described friction top simultaneously.Turn clockwise lock screw time, can there is the motion to rotor shaft direction in friction top, otherwise then friction top can move to the direction away from rotating shaft.According to the working principle of expansion sleeve, in the locked condition, turn clockwise lock screw, the inside circulating application of friction top is made to add active force, make mutually to push against between running shaft, inside and outside ring and shell, the internal diameter of inner ring reduces banding rotating shaft, and the external diameter of outer shroud increases and stretching shell endoporus, between each surface of contact, produce pressure, thus generation frictional force and friction torque are to reach the object of locking.In the released state, be rotated counterclockwise lock screw, inside and outside ring is thrown off, and running shaft can realize free rotation, thus realizes quick locking at any angle and the release of axial workpiece.
Particularly, the part that described lock screw is connected with described friction top is left-handed thread, and the part that described lock screw is connected with described connecting cover is right-handed thread; The end of described axle sleeve is provided with flange, and described flange is fixedly connected with described fixed bearing by bolt; The spline for preventing described friction top from rotating is provided with between described friction top and described shell.
Beneficial effect of the present invention is:
The present invention can realize locking and the release of locking device easily and fast by of a locking device shaft core position lock screw, and can ensure that inside and outside ring is in the process of locking and unclamp, inside and outside ring is fitted simultaneously, make its uniform force, greatly improve the working life of locking device, meanwhile, this structural type makes the process discharging and lock become more simple, substantially increases working efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1: the present invention includes lock screw 1, connecting cover 2, shell 3, friction top 4, inner ring 5, outer shroud 6, fixed bearing 7 and axle sleeve 9, axle sleeve 9 is set on running shaft 8, fixed bearing 7 is provided with endoporus, fixed bearing 7 is loaded on axle sleeve 9 by inner hole sleeve, inner ring 5 and outer shroud 6 are all set in running shaft 8 end circumferentially, the inner side of outer shroud 6 is by thick gradually thin inclined-plane with the direction of close axle sleeve 9, the outside of inner ring 5 is thin-to-thick inclined-plane with the direction near axle sleeve 9, outer shroud 6 contacts with each other with the inclined-plane of inner ring 5, friction top 4 is arranged at the end face of running shaft 8 and is connected with inner ring 5 by screw, one end of shell 3 is installed on the periphery of outer shroud 6 and is fixedly connected with fixed bearing 7, connecting cover 4 is fixedly connected with the other end of shell 3, lock screw 1 is also threaded connection with connecting cover 2 and friction top 4 through connecting cover 2 and friction top 4 simultaneously.The part that lock screw 1 is connected with friction top 4 is left-handed thread, and the part that lock screw 1 is connected with connecting cover 2 is right-handed thread; The end of axle sleeve 9 is provided with flange, and flange is fixedly connected with fixed bearing 7 by bolt; The spline for preventing friction top 4 from rotating is provided with between friction top 4 and shell.
As shown in Figure 1: turn clockwise lock screw 1 time, can there is the motion to rotor shaft direction in friction top 4, otherwise then friction top 4 can move to the direction away from rotating shaft.According to the working principle of expansion sleeve, in the locked condition, turn clockwise lock screw 1, friction top 4 is made to apply active force to inner ring 5, make mutually to push against between running shaft 8, inner ring 5, outer shroud 6 and shell 3, the internal diameter of inner ring 5 reduces banding running shaft 8, and the external diameter of outer shroud 6 increases and stretching shell 3 endoporus, between each surface of contact, produce pressure, thus generation frictional force and friction torque are to reach the object of locking.In the released state, be rotated counterclockwise lock screw 1, inside and outside 5 rings are thrown off, and running shaft 8 can realize free rotation, thus realizes quick locking at any angle and the release of axial workpiece.
