The self-locking taper pin that single, assembly precision is high, security is good.
To solve this technical problem, the utility model provides a kind of locking taper pin of self-locking, including taper pin, bullet
Property axle sleeve, plain washer, stop washer and round nut, the tapered rod structure of taper pin, its miner diameter end be provided with locking screw；
The elastic shaft sleeve endoporus is bellmouth, and the taper of the bellmouth is adapted to taper pin, and the elastic shaft sleeve is indulged provided with two
To opening two semi-elastic axle sleeves of formation, its external diameter is adapted to part hole to be connected, and boss is provided with the bigger diameter end of bellmouth；It is described
Taper pin and elastic shaft sleeve fit are put into connection member hole, and stop washer and circle spiral shell are externally provided with the locking screw of taper pin
Mother, is provided with plain washer between stop washer and elastic shaft sleeve.
The locking screw of the taper pin is externally provided with step.
Beneficial effect：The utility model is used cooperatively using taper pin and two semi-elastic axle sleeves, and being arranged on after fit has
At the assembly connection of degree of precision requirement, taper pin makes between hole axle without any gap, passes through stop washer round nut fixed cone
Degree pin, without any gap between installation locking rear axle, hole, in stationary fit state.The utility model is simple in construction, and interchangeability is high,
Assembly precision is high, safe, installs, dismantles fast easily, it is adaptable to has the assembly connection of degree of precision requirement.

Embodiment
Below in conjunction with the accompanying drawings and embodiment is specifically described to the utility model.
Fig. 1 show structural representation of the present utility model.
The utility model includes taper pin 1, elastic shaft sleeve 2, plain washer 5, stop washer 6 and round nut 7, for two connections
Connection between part, auto lock simultaneously has locking functions.
Fig. 2 show the structural representation of the utility model taper pin.
Fig. 3 show the utility model Fig. 2 A-A diagrammatic cross-sections.
The tapered rod structure of the taper pin 1, its miner diameter end is provided with locking screw 9, to lock and locking.
The locking screw 9 of the taper pin 1 is externally provided with step 10, and locking screw is protected during for dismantling, and prevents its damage.
Fig. 4 show the structural representation of the utility model elastic shaft sleeve.
Fig. 5 show the utility model Fig. 2 B-B diagrammatic cross-sections.
The endoporus of elastic shaft sleeve 2 is bellmouth, and the taper of the bellmouth is adapted to taper pin 1, its external diameter with it is to be connected
Part hole is adapted to.
The elastic shaft sleeve 2 is divided into two to form two semi-elastic axle sleeves provided with two longitudinal openings 8, is easy to taper pin
1 locking fastening is installed, and eliminates gap between fitted shaft, hole.
The bigger diameter end of the bellmouth of elastic shaft sleeve 2 is provided with boss 11, for fixing axial location.
Taper pin 1 and elastic shaft sleeve 2 fit is put into connection member hole, is externally provided with the locking screw 9 of taper pin 1
Stop washer 6 and round nut 7, are provided with plain washer 5, further taper pin are tightened and prevented between stop washer 6 and elastic shaft sleeve 2
Pine.
Operation principle of the present utility model
It is described as follows by taking connector I3 and connector II4 connection as an example：
Taper pin 1 and the fit of elastic shaft sleeve 2 are put into connector I3 and connector II4 connecting hole, beat taper pin 1 big
Footpath end, makes the slowly tensioner of elastic shaft sleeve 2, until, in stationary fit state, being sequentially placed into flat without any gap between fitted shaft, hole
Packing ring 5, stop washer 6, tighten round nut 7, effectively can tighten taper pin 1 and locking.During dismounting, round nut 7 is unclamped, according to
Secondary take removes stop washer 6, plain washer 5, beats at the miner diameter end end step 10 of taper pin 1, ejects taper pin 1.
The utility model is used cooperatively using taper pin and two semi-elastic axle sleeves, and being arranged on after fit has degree of precision to want
At the assembly connection asked, taper pin makes without any gap between hole axle, passes through stop washer round nut and fixes taper pin, installs lock
Tightly without any gap between rear axle, hole, in stationary fit state.The utility model is simple in construction, and interchangeability is high, and assembly precision is high,
It is safe, install, dismantle fast easily, it is adaptable to have the assembly connection of degree of precision requirement.
The utility model the embodiment above, is merely illustrative, be not it is only, it is all in the range of the utility model
Or the change in the range of equivalent the utility model is surrounded by the utility model.
