Summary of the invention
In order to solve when prior art Elastic pin assembles, labour intensity is large, security is not high and the problem of inconvenience, and the utility model provides a kind of resilient key assembly tool.
The technical solution of the utility model is: a kind of resilient key assembly tool, comprise pneumatic air pressure gun, it is characterized in that: on the housing of pneumatic air pressure gun, outer sleeve is installed, outer sleeve concentric ring is peripheral around the rotating shaft of pneumatic air pressure gun, the rotating shaft of pneumatic air pressure gun is fixedly connected with a screw rod, screw rod is threaded with an inner sleeve again, and the cylindrical of inner sleeve and the endoporus of outer sleeve are axial sliding fit, and inner sleeve is spacing by circumference relative to outer sleeve by stop pin device;
The endoporus of inner sleeve is resilient key leadout hole, transition tapered hole, resilient key load hole, threaded connection hole from outside to inside successively, and the cylindrical of inner sleeve is provided with resilient key and puts into groove and resilient key load hole is through; The diameter of resilient key leadout hole is less than resilient key external diameter, to keep the confined state of resilient key; The diameter of resilient key load hole is larger than resilient key external diameter;
Described screw rod is connected with the threaded connection hole of inner sleeve, realizes being threaded between screw rod with inner sleeve;
When the axis of rotation of pneumatic air pressure gun, inner sleeve moves inward, resilient key in resilient key load hole is outwards ejected by screw rod outer face, resilient key is through transition tapered hole, its external diameter of resilient key is reduced gradually, and resilient key enters resilient key leadout hole, and resilient key continues outwards mobile, and then in loading hole in piece part, reach the object easily loaded.
Further restriction to technique scheme: the rotating shaft side of the being provided with mortise of pneumatic air pressure gun, the screw rod side of being provided with tenon, square tenon is connected with square mortise, thus realizes screw rod and be fixedly connected with in the rotating shaft of pneumatic air pressure gun.
Further restriction to technique scheme: the diameter 0.1-0.3 millimeter less of resilient key external diameter of resilient key leadout hole, when resilient key is loaded in hole in piece part, resilient key and hole in piece part are in being slidably matched, and resilient key is easily correctly loaded.
Limiting again technique scheme: the length of resilient key leadout hole is 5-10 millimeter, the length of transition tapered hole is 4-8 millimeter, and the setting of this dimensional parameters is optimized combination, and the compression of resilient key of being more convenient for and derivation reach the optimization of total.
The beneficial effects of the utility model: the utility model carries out vibrational power flow on the basis of existing pneumatic air pressure gun, utilize the characteristic be threaded to realize relative motion cleverly, and first elasticity of compression pin, reinstalls in hole in piece part, reach the object easily loaded.And be easy to operation, security is high, and labour intensity is little.
