For the less mechanical connection of driving torque, prior art is tapping on axle sleeve, withstands on the mandrel with screw rod, realizes the transmission purpose.Or clamp mandrel with clamp, realize the transmission purpose.If need often to adjust the transmission that the position can not be damaged the velocity ratio such as the plastic cement die-cutting machine cylinder of mandrel again for some, adopt prior art, just there are some defectives, such as, can damage mandrel; Position adjustment trouble, cost is high.Existing on the market mandrel lock can only axially locating, can not transmitting torque, therefore, need badly a kind of simple in structure, easy to install, can driving torque and do not damage the new equipment of mandrel.
The model utility content
The purpose of this utility model is, overcomes the above-mentioned defective of prior art, provides a kind of simple in structure, easy to install, can driving torque and do not damage the mandrel lock of mandrel.
For realizing described purpose, the technological scheme that the utility model provides is as follows: construct a kind of mandrel lock, comprise the axle sleeve that is provided with the shaft shoulder, be socketed in the lock sleeve on the axle sleeve, the locking handwheel that is threaded with lock sleeve, described axle sleeve upper end offers some slots, its underpart offers three stepped grooves, card is inserted with the locking jaw of the corresponding band hypotenuse of shape in the described stepped groove, the internal diameter of described lock sleeve offers interior step, and step joint offers and the corresponding oblique groove of axle sleeve in this.
Described lock sleeve outer peripheral surface offers outside thread, and the inner chamber of described locking handwheel offers some steps, and its middle bench offers internal thread, and the outside thread of described lock sleeve is connected with described locking handwheel internal thread.
Described axle sleeve middle part is socketed with a pressure spring, and this pressure spring is installed in the inner chamber place that described lock sleeve is threaded with the locking handwheel.
Described axle sleeve lower end is provided with the handle of a pulling axle sleeve slippage, and this handle bottom offers a circular ring slot, closely is connected with an annular buckle in this circular ring slot.
When the described locking handwheel of described lock sleeve screw thread screws, drive the locking jaw be fastened on axle sleeve and move along the oblique groove of lock sleeve, described locking jaw is extruded inward, and will place the mandrel locking of bore sleeve.
Described locking jaw is three.
Working principle of the present utility model is, during installation, the axle sleeve cover is received on the mandrel, rotational lock overlaps and the locking handwheel relatively, locking jaw by the inside compressive zone hypotenuse of the oblique groove that is located at lock sleeve, locking jaw is pushed to the axle center, and this locking jaw compresses the axle circumferential surface, makes lock sleeve and mandrel closely link together.
Usefulness of the present utility model is, simple in structure, easy installation and removal, can axially locating again can transmitting torque and do not damage mandrel, cost of production is low, and being particularly suitable for needs often to adjust the transmission that the position can not be damaged the velocity ratio such as the plastic cement die-cutting machine cylinder of mandrel again at some.
