Abstract
The utility model discloses a shaft locking device, comprising a shell, a lock sleeve, a lock pin, a pressure spring, a lock bead and a lock opening device. The lock sleeve is fixed on the shell, one end of the lock pin is inserted in the lock sleeve, the pressure spring is provided between the lock sleeve and the lock pin, respectively supporting and pressing on the lock sleeve and the lock pin. A plurality of holes are processed on the side wall of the lock sleeve in which the lock pin is inserted, and one lock bead is uniformly arranged in each hole. Corresponding with the positions of the lock beads, a pyramidal face segment matching with the lock beads or a plurality of oblique planes which are annularly arranged are processed in the inner hole of the lock sleeve. The lock opening device is used to control the positions of the pyramidal face segment relative to the lock beads or the oblique planes by controlling the degree of inserting the lock sleeve of the lock pin in order to realize the locking and loosening of an axle. The shaft locking device of the utility model can generate strong locking force under the action of minor force, and in addition, a core axle can not be scratched synchronously at the time of locking the core axle. The shaft locking device is of convenient control, and it isan ideal shaft locking device.
Description
Technical field
The utility model relates to a kind of locking device, especially a kind of locking device that can lock the axial motion rod member.
Background technique
At present, the axis and shaft parts axial locking device has many kinds, commonly used jackscrew arranged, hold cover tightly, spring clip is first-class, jackscrew locking and positioning coupling mechanism force is little, and easily scratch mandrel, though hold cover tightly and the spring chuck coupling mechanism force is bigger,, can't use under the situation little in the space, that usage quantity is many because its volume ratio is bigger.
The model utility content
At the deficiencies in the prior art, the purpose of this utility model provide a kind of coupling mechanism force big, take up room little, the axle locking device that is easy to control.
For achieving the above object, the utility model axle comprises shell with locking device, lock tube, lock core, stage clip, the lock pearl, unlocking device, lock tube is fixed on the shell, lock core one end inserts in the lock tube, stage clip is arranged between lock tube and the lock core, and the difference roof pressure is on lock tube and lock core, lock core inserts on the lock tube one distolateral wall and is processed with several holes, be provided with a lock pearl in each hole, corresponding with the position of lock pearl, be processed with in the hole in the lock tube and lock conical surface section that pearl matches or several inclined-planes of arranging in the form of a ring, unlocking device inserts the degree of lock tube by the control lock core, come the position on relative conical surface section of control lock pearl or inclined-plane, to realize the locking of axostylus axostyle and to loosen.
Further, described lock pearl is spheroid or running roller.
Further, described unlocking device is leverage or cam mechanism or linkage mechanism or cylinder.
Further, described unlocking device is the arm-tie of unblanking that has inclined working.
Further, be symmetrically arranged with the locking mechanism that two covers are made of lock tube, lock core, stage clip, lock pearl on the described shell, the shared unlocking device of two cover locking mechanisms, this unlocking device draws the utmost point for unblanking, this arm-tie bilateral symmetry of unblanking is provided with two inclined working, lock core in the two cover locking mechanisms is leaning respectively under the effect of its stage clip on the inclined working relative with it on the arm-tie of unblanking, and the arm-tie of unblanking is realized the control to the lock core axial motion by axial displacement.
The utility model axle under less strength effect, can produce very strong coupling mechanism force with locking device, and can not scratch mandrel in the locking mandrel, and this axle is easy with locking device control, is a kind of desirable axle locking mechanism.
Description of drawings
Fig. 1 is the utility model sectional view;
Fig. 2 is an A-A view among Fig. 1.
Embodiment
As shown in drawings, the utility model axle comprises shell 1, lock tube 3, lock core 7, stage clip 6, lock pearl 5, the arm-tie 8 of unblanking with locking device, lock tube 3 is fixed on the shell 1, lock core 7 one ends insert in the lock tube 3, stage clip 6 is arranged between lock tube 3 and the lock core 7, and the difference roof pressure is on lock tube 3 and lock core 7, lock core 7 inserts on the lock tube 3 one distolateral walls and is processed with several holes, be provided with a lock pearl 5 in each hole, corresponding with the position of lock pearl 5, be processed with in 3 li holes of lock tube and lock the conical surface section 4 that pearl 5 is matched, lock pearl 5 is a steel ball.The arm-tie of unblanking is provided with the locking mechanism that two covers are made of lock tube 3, lock core 7, stage clip 6, lock pearl 5 in both sides about in the of 8, the shared arm-tie 8 of unblanking of two cover locking mechanisms, up and down lock core 7 one ends respectively roof pressure on the arm-tie inclined-plane that both sides are provided with about in the of 8 of unblanking, match with the arm-tie 8 of unblanking for the ease of lock core 7, lock core 7 surface of matching with inclined-plane on the arm-tie 8 of unblanking is arc surface.
Conical surface section 4 in 3 li holes of lock tube also can be by several and the surface groove replacement one to one of lock pearl 5.
When the utility model used, axostylus axostyle 2 inserted in lock tube 3 and the lock core 7, and lock pearl 5 one sides are pressed on axostylus axostyle 2 surfaces, and its opposite side is pressed on the inclined-plane of conical surface section 4.Under the effect of stage clip 6, lock core 7 one ends lean on the inclined working of arm-tie 8 of unblanking.When the arm-tie 8 of unblanking was positioned at position shown in Figure 2, lock core 7 was in maximum and stretches out state, and lock pearl 5 tightly is being pressed under the effect of conical surface section 4 on axostylus axostyle 2 surfaces, and with axostylus axostyle 2 lockings; When needs get loose axostylus axostyle 2, then need to spur or promote to unblank arm-tie 8 to left side shown in Figure 2, at this moment lock core 7 by the inclined working roof pressure on the arm-tie 8 of unblanking to lock tube 3, the horizontal activity space of thereupon locking pearl 5 is extended in conical surface section 4, and the tight contact condition of releasing and axostylus axostyle 2, axostylus axostyle 2 is got loose.
Unblanking arm-tie 8 also can be by cam mechanism or leverage or linkage mechanism replacement, and these mechanisms only need to make lock core 7 to produce axial displacements and get final product.Lock pearl 5 can be replaced by running roller, matches with it, and 4 need of conical surface section in 3 li holes of lock tube are made the surface groove that width and running roller match.
