Chain or steel wire rope fatigue fracture after, vertical component is because of Gravitational sliding；3rd, there was only hydraulic accumulator balance, because accumulator balances
Failure or pipeline leak and generate vertical component because of Gravitational sliding.The presence of these defects can make the vertical component of numerically-controlled machine tool exist
The accidents such as accident causes operating personnel injured when sliding down, machine tool accuracy is damaged, and cutter destroys, and workpiece surface is damaged, are caused
Unnecessary economic loss.
Utility model content
Problem to be solved in the utility model is to provide a kind of protective device for numerically-controlled machine tool.The device may be such that
When vertical lifting part slides down, movable plate can be driven to rotate, so that generating frictional force between movable plate and fixed part, led to
Frictional force is crossed first to delay and then prevent rotation, so as to which lifting part be avoided surprisingly to slide.
The technical solution that the utility model solves the above problems is as follows：
A kind of protective device for numerically-controlled machine tool, the rotation section including fixed part and with fixed part rotation connection,
The rotation section includes the shaft being sleeved in the fixed part, and the rotation section also includes being sleeved in the shaft successively
Movable plate, the plane bearing being sleeved in the shaft, are sleeved in the shaft disk spring being sleeved in the shaft
Gasket and be sleeved on the roller end tighten nut；The movable plate is connected with the shaft by spline, and described
The friction plate on the fixed part is provided between the lower end surface of movable plate and the upper end end face of the fixed part.
Preferably, the movable plate upper end is provided with the peace convenient for plane bearing installation close to the position of the shaft
Tankage.
Preferably, further including several balls, the fixed part upper end is provided with close to the position of the shaft convenient for institute
State the mounting groove of ball installation.
Preferably, the fixed part is directly connected with the shaft by deep groove ball bearing.
Preferably, the lower end of the shaft is arranged to the outer-hexagonal that the rotary screw rod with numerically-controlled machine tool is convenient for connect
End.
Preferably, the protective device further includes case, the movable plate upper end end face is equipped with thread groove；The cover
Clamshell is located above the gasket, and the screw thread for passing through case is screwed with the thread groove and is connected.
Preferably, the protective device further includes end plug, the case end face is equipped with tightens nut convenient for described
The through hole inserted, and the through hole and described tighten have gap between nut；The end plug plug is swollen in the gap.
The utility model has the advantages that compared with prior art：
1st, after the utility model is correctly installed, the gravity that numerically-controlled machine tool vertical component generates when gliding drives vertical screw rotation
When turning, while the rotation of shaft also being driven, shaft rotation can drive movable plate to be rotated compared with the fixed part for being equipped with friction plate, from
And larger frictional resistance is generated, which can be adjusted by being arranged on the nut of tightening of end；It usually can be by this
Frictional force is adjusted to a suitable scope vertical screw to be prevented to rotate, so as to achieve the purpose that vertical mechanism cannot glide.
2nd, the utility model can be solved because of the vertical component of numerically-controlled machine tool because mechanical balance damage failure, motor internal contracting brake fail,
It may result in that operating personnel are injured, machine tool accuracy is damaged, cutter destroys, workpiece surface is bruised because gravity slides down etc. and ask
Topic.
3rd, the utility model can be applicable on a variety of numerically-controlled machine tools with vertical component, such as boring machine, milling machine, punching machine.
