Description

A kind of forced locking device
Technical field
The present invention relates to locking device, mainly a kind of forced locking device that can design according to transmission shaft size.
Background technique
Along with industry and Machinery Automation development are maked rapid progress, it is just essential that machinery realizes the many actions of many drivings, drive transmission shaft used just more extensive to needing transferring power, requirements at the higher level be there has also been to transmission shaft simultaneously, it is also no longer traditional bolt that transmission shaft connects, key, spline, pins etc. are connected to, needs can meet the needs that complete machine is arranged, transmission shaft transmission of drive force is installed in particular space, just cannot realizes the conventional method that spline joint bolt and pin fix, more impossiblely to load and unload.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and a kind of all difficult problems because loading and unloading by spatial constraints that solves are provided, and handling are extremely put just, the forced locking device that reliability is strong.
The object of the invention is to have come by following technical solution, it comprises spline joint fork, sliding ring, ball lock block, and the external diameter of described spline joint fork offers draw-in groove, and in this draw-in groove, card has eccentric hoop; Described ball lock block is placed on spline joint fork, and is close proximity to the side of eccentric hoop; Accompany big spring between this ball lock block and stop ring, stop ring is limited on the step trough of spline joint fork, and stop ring, ball lock block are positioned at sliding ring, and sliding ring is placed on spline joint fork.
As preferably, described eccentric hoop offers inside groove, in this inside groove, be placed with the little spring withstood with sliding ring.
As preferably, the radial cross section below the draw-in groove of described spline joint fork offers three through holes through with draw-in groove, these three through holes are 120 ° and are uniformly distributed; Steel ball is placed with in this through hole.
As preferably, the port end of described spline joint fork is provided with a groove, and interior card has outer snap ring; The inwall of sliding ring is provided with groove, and interior card has interior snap ring.
Beneficial effect of the present invention is: it is convenient that forced locking device overall construction design manufactures, install and use and put just, general character design of material is used to become to realize compound action principle, reach overall structure stability with these material specificity, need high-speed rotary turntable to accomplish to transmission shaft not only safe but also attractive in appearance.

Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the present invention: as shown in accompanying drawing 1,2,3,4, the present invention includes spline joint fork 1, sliding ring 3, ball lock block 5, the external diameter of described spline joint fork 1 offers draw-in groove 11, and in this draw-in groove 11, card has eccentric hoop 7; Described ball lock block 5 is placed on spline joint fork 1, and is close proximity to the side of eccentric hoop 7; Accompany big spring 4 between this ball lock block 5 and stop ring 2, stop ring 2 is limited on the step trough of spline joint fork 1, and stop ring 2, ball lock block 5 are positioned at sliding ring 3, and sliding ring 3 is placed on spline joint fork 1.
Described eccentric hoop 7 offers inside groove 71, in this inside groove 71, is placed with the little spring 6 withstood with sliding ring 3.Radial cross section below the draw-in groove 11 of described spline joint fork 1 offers three through holes 12 through with draw-in groove 11, these three through holes 12 are 120 ° and are uniformly distributed; Steel ball 9 is placed with in this through hole.The port end of described spline joint fork 1 is provided with a groove 20, and interior card has outer snap ring 8; The inwall of sliding ring 3 is provided with groove 20, and interior card has interior snap ring 10.
Installation process of the present invention is: the concrete first step, pitch on 1 external diameter at spline joint and process draw-in groove 11, circumferentially certain is a bit to push up sliding ring 3 by a little spring 6, sliding ring 3 is made to produce bias, this little spring 6 is stuck in spline joint fork 1 and overlap in the inside groove 71 on the eccentric hoop 7 that has, blocks sliding ring 3 and forced locking device is in wait to lock front state (before also installing with regard to product).Second step, product starts installation, when driving-shaft assembly starts to load splined shaft, splined shaft chamfering to push up to large footpath in spline joint fork 1 120 degree divide equally three steel balls 9 time, steel ball 9 slowly pushes up and is stuck in sliding ring 3 in groove under splined shaft effect, bias is constantly found accurately, until with spline joint pitch 1 external diameter concentric time, under in forced locking device, big spring 4 acts on, move down to ball lock block 5 inclined-plane and withstand steel ball 9, splined shaft continues to enter, until steel ball 9 enters in all R grooves in splined shaft garden, splined shaft also cannot enter and retreat, simultaneously ball lock block 5 is because of after steel ball 9 enters splined shaft R groove, ball lock block 5 is also moved to fixed position in big spring 4 thrust, steel ball 9 is locked, reach the axial locking effect of splined shaft, complete transmission one end installation process.3rd step, transmission shaft to be dismantled on main frame, very simply, as long as the housing of forced locking device is upwards pushed away, shift fixed position onto, ball lock block 5 removes steel ball 9, and splined shaft from by pulling out, can treat that splined shaft exits steel ball position steel ball 9 with regard to free fall, sliding ring 3 is under little spring 6 acts on, produce and partially listen bias, sliding ring 3 card entry slot internal fixtion, just completes transmission shaft unloading process.
