Referring to fig. 1-2, the present embodiment is directed to provide a quick grooving tool for the surface of a password wheel, including a placement table 1, a height increasing table 2 is fixedly installed on the placement table 1, a grooving mechanism for grooving the surface of the password wheel is fixedly installed on the height increasing table 2, a motor 101 is fixedly installed on the placement table 1, a rotating shaft 102 is fixedly installed on an output shaft of the motor 101, a tensioning mechanism is provided on the rotating shaft 102, the tensioning mechanism is used for fixing the password wheel on the rotating shaft 102, and the tensioning mechanism is located below the grooving mechanism.

In order to better adapt to the shape of the password wheel, the password wheel is sleeved on the rotating shaft 102 for slotting, so that the plane of the placing table 1 is prevented from being damaged in the slotting process. Also, the height increasing table 2 can save the space for placing the table 1, so that the rotation of the rotating shaft is not affected by the small motor 202. The motor 101 can set a single rotation angle for adapting to the rotation of the rotating shaft 102 on the output shaft, so as to achieve the control of the slotting number of the coded wheel.

Wherein, in order to adapt to the internal diameter and the width of different cipher wheels, set up special spacing fixture block 1021 and spacing nut 1022 fixed to cipher wheel position, spacing fixture block 1021 is trapezium structure, owing to there is annular arrangement's spring 1023 inside pivot 102, can support spacing fixture block 1021 and expose in the spout 1024 outside completely under the spring 1023 state of relaxing, accessible spacing nut 1022 makes spring 1023 compress completely and reaches spacing fixture block 1021 and retract into spout 1024 inside completely, spacing fixture block 1021 can be fixed the cipher wheel tensioning, and spring 1023 elasticity coefficient can satisfy the demand of supporting the cipher wheel, the inside screw thread of spacing nut 1022 can be adjusted according to the width of cipher wheel.

It is to be added that the limit nut 1022 is in threaded connection with the rotating shaft 102, the limit nut 1022 is rotated and simultaneously moved along the rotating shaft 102, meanwhile, the surface of the limit clamping block 1021, which is opposite to the limit nut 1022, is a smooth inclined surface, the inclined surface of the limit nut 1022 is extruded while the limit nut 1022 is moved, so that the limit nut 1022 is promoted to move towards the inside of the sliding groove 1024, the size of the plurality of limit clamping blocks 1021 extending out of the sliding groove 1024 is changed in such a way, when the limit clamping blocks 1021 completely submerge into the sliding groove 1024, the password wheel can be sleeved on the rotating shaft 102, then the limit nut 1022 is rotated, the limit clamping blocks 1021 are outwards unfolded under the action of the resilience force of the spring 1023 by extrusion, the password wheel is tensioned and fixed, and simultaneously, the tightening and fixing of the password wheels with different inner diameters can be met according to the size of the limit clamping blocks 1021 extending out of the sliding groove 1024.

Furthermore, the surface of the limiting clamping block 1021, which is opposite to the password wheel, is a horizontal plane, namely the surface adjacent to the inclined plane is a horizontal plane, the center of the password wheel is positioned on the horizontal plane, and the password wheel is clamped and fixed by the horizontal plane of the limiting clamping block 1021, so that the stability of clamping and fixing is ensured.

Further, the small motor 202 is slidably engaged with the raising platform 2, and the small motor 202 is displaced on the raising platform 2 by the air pressure of the air cylinder 201. The maximum displacement of the cylinder 201 acting on the small motor 202 is that the small motor 202 is 10cm away from the heightening platform 2 and is close to the end of the rotating shaft 102, so that the small motor 202 is prevented from sliding out of the heightening platform 2, and the reliability of the slotting tool is improved.
