Description
Technical field
The utility model belongs to mounting technology field, specifically relates to a kind of micro rod elastic spring quick-fitting device.
Background technology
Be illustrated in figure 2 axle-steel silk back-up ring, axle-steel silk back-up ring is circular ring structure, in annulus circumferential openings.Usually support the use with D hook bolt as shown in Figure 1, be mainly used in compact conformation and narrow and small two parts of intracavity space connect.In assembly connection process, due to the restriction by compact conformation, narrow space, two Assembly of the parts, to after together, cannot, from inner chamber assembling bolt, more cannot use spanner to screw.Therefore before two parts are unassembled, first D hook bolt 1 is loaded in the connecting hole of certain part, the D head circumference of D hook bolt 1 is placed in anti-rotation position, afterwards axle-steel silk back-up ring 2 is assembled on the bolt axle journal 1b of D hook bolt 1, after D hook bolt 1 is blocked bolt axle journal 1b by axle-steel silk back-up ring 2, when not having other to retrain, D hook bolt 1 being hung on and is assembled in the connecting hole of part.
In order to realize in the bolt axle journal 1b being assembled to as shown in Figure 1 by axle-steel silk back-up ring 2 as shown in Figure 2, traditional method uses combination pliers to assemble, concrete operation method combination pliers is clamped pin close, and fill in the inner ring 2a of axle-steel silk back-up ring 2, then open combination pliers pincers pin, make axle-steel silk back-up ring 2 softened; When the size of axle-steel silk back-up ring 2 bayonet socket is more than or equal to the bolt axle journal 1b diameter of D hook bolt 1, push shaft elastic spring 2 is held level with both hands to bayonet socket, axle-steel silk back-up ring 2 is entered in the bolt axle journal 1b of D hook bolt 1, finally unclamps combination pliers, complete the assembling of axle-steel silk back-up ring 2.
Because axle-steel silk back-up ring 2 is very fine, therefore adopt traditional assembly method more difficult.When assembling, main exist following not enough: the first, need to manufacture and design special combination pliers, this combination pliers two clamps the inner ring diameter that size that pin merges must be less than axle-steel silk back-up ring 2, so just realizes the possibility of assembling; Because tiny combination pliers pincers pin intensity is weak, misoperation easily fractures; Second, owing to adopting combination pliers hand-manipulated, pincers heel brace opening amount is restive, and when the combination pliers amount of strutting hour, axle-steel silk back-up ring 2 can not load the bolt axle journal 1b of D bolt 1, when the combination pliers amount of strutting is excessive, the easily intrinsic elasticity of broken annulate shaft elastic spring 2, when unclamping combination pliers pin, axle-steel silk back-up ring 2 can not be returned to original state, bolt axle journal 1b can not be blocked, cause assembling unsuccessfully; 3rd, because the structure of axle-steel silk back-up ring 2 is fine, during assembling, combination pliers pin occupies certain space, and the theory of combination pliers struts that size is larger than bolt axle journal 1b manyly just can complete assembling; 4th, when axle-steel silk back-up ring 2 is sent into bolt axle journal 1b or extracts combination pliers by combination pliers, easily damage bolt thread 1a and bolt axle journal 1b; 5th, adopt combination pliers assembling benefit lower, completing 1 micro rod elastic spring needs about 30 minutes, wastes time and energy, greatly reduces efficiency of assembling.
