Description
Affiliated technical field
The utility model belongs to machine tool field, especially lathe ball-screw brake apparatus.
Background technology
At present, the axially-movable of Digit Control Machine Tool mainly drives with ball screw assembly.Generally; the ball screw assembly, that plummet uses is bearing the force action of tractive force and axle of the plummet parts gravity; because ball screw assembly, can not self-locking; so; under the stopped status; axle of the plummet parts meeting natural downslide, present known solution has two kinds of forms: increase counterweight or adopt balancing cylinder.But these two kinds of methods all have shortcoming separately: increase counterweight, the quality of moving component is increased, inertia strengthens, and acceleration diminishes, and the fast moving degree reduces.And the employing balancing cylinder then need increase hydraulic system, makes machine tool structure complicated more, also increases cost.
Summary of the invention
The purpose of this utility model provides a kind of lathe ball-screw brake apparatus of containing that the axle of the plummet parts glide.
To achieve these goals, the technical scheme that the utility model is taked is: a kind of lathe ball-screw brake apparatus, comprising: ball-screw, bearing, bearing cap, cover, nut, Brake Block, the leading screw seat, bearing is passed through on the top of ball-screw, bearing cap, cover and nut are contained on the leading screw seat, the leading screw seat is packed on the lathe body, Brake Block is packed on the lathe body, be characterized in: this lathe ball-screw brake apparatus also comprises the servomotor that has built-in electricity loss brake, the external electricity loss brake that has moving plate, servomotor and ball-screw are in transmission connection, external electricity loss brake is contained between leading screw seat and the Brake Block, the moving plate of external electricity loss brake is fixedly mounted on the ball-screw, and the matrix of external electricity loss brake is fixedly mounted on the Brake Block.
When servomotor is worked, built-in electricity loss brake, external electricity loss brake all are in "on" position, there is not braking action, when the servomotor inoperative or when breaking down, built-in electricity loss brake, external electricity loss brake are in off-position, and brake, thereby ball screw assembly, can't be moved, promptly contained the downslide of Digit Control Machine Tool axle of the plummet parts.
The beneficial effects of the utility model are, can replace the counterweight and the balancing cylinder of Digit Control Machine Tool axle of the plummet, do not have the shortcoming of counterweight and balancing cylinder, and are simple in structure.
