Abstract
The utility model relates to a taper pin with a lock, including a pin shaft and a elastic shaft sleeve which is arranged outside the shaft and provided with a vertical opening. The pin shaft agrees with the elastic shaft sleeve, and the shaft is fixed by a locking screw in the shaft shorter-diameter end and a nut. In use, the pin shaft and the elastic shaft sleeve are arranged at the assembling joint of interchangeable parts which require relatively high precision, and fixed by the locking screw. Then a locking back shaft is installed and leaves no clearance to realize static combining status, high assembling precision, and convenience for installment and dismounting.
Description
Technical field
The utility model relates to a kind of mechanical connecting element, specifically a kind of tight tapering pin with lock.
Background technique
We know, the column type bearing pin that mechanically uses at present is difficult for installing, dismounting, and need certain fit up gap between axle, hole, can not satisfy the assembling that degree of precision requires and connect, and not being suitable for has the assembling of the interchangeability parts that degree of precision requires to connect.
Summary of the invention
The utility model provides a kind of simple in structure for overcoming above-mentioned the deficiencies in the prior art, and no any gap between locking rear axle, hole is installed, and is in the stationary fit state, and the assembly precision height is installed, dismantled fast easily, the with lock tight tapering pin that Security is higher.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of tight tapering pin with lock, it includes the bearing pin and the elastic shaft sleeve of band tapering, elastic shaft sleeve is located at the outside of bearing pin, and the less end of pin diameter is provided with locking nut, and elastic shaft sleeve is provided with longitudinal opening.
Outside the locking nut of bearing pin, be provided with locking nut, be provided with pad between locking nut and the elastic shaft sleeve.
The utility model adopts the bearing pin and the elastic shaft sleeve of band tapering to match, and is provided with locking nut in the smaller diameter end of bearing pin, by the locking nut fixed pin shaft.During use, the bearing pin of tight screw with lock and elastic shaft sleeve are installed in the assembling joint of the interchange components that degree of precision requires, fix by locking nut again, no any gap between locking rear axle, hole is installed, be in the stationary fit state, the assembly precision height is installed, dismantles easily quick.
