Abstract
The utility model discloses a linear rotary shaft of a numerical-control machine tool, which comprises a motor and a nut. The motor is fixedly arranged on the top of a framework, a lead screw is fixedly connected onto a rotating shaft of the motor and matches with the nut, a saw-shaped gear is movably connected to the other end of the lead screw and meshed with a gear, a limiting block used for limiting the saw-shaped gear is disposed on the framework, the lead screw rotates to drive the saw-shaped gear to linearly move, the saw-shaped gear drives the gear to rotate so that a spindle swings left and right, and accordingly linear movement is changed into rotational movement. The linear rotary shaft has the advantages of small occupied space, large torque and high precision, and is used for adding a fourth shaft to the numerical-control machine tool.
Description
Technical field
The utility model relates to a kind of Digit Control Machine Tool, specifically, relates to a kind of Digit Control Machine Tool straight line rotating shaft, belongs to field of mechanical technique.
Background technology
At present, general Digit Control Machine Tool can only move up and down, can not rotate owing to knife rest, thereby has determined a kind of equipment can only realize a kind of processing mode; The main shaft of numerical control machine tool that has can rotate, but complex structure, precision is low, and moment of torsion is little, and turbine and worm speed is slow, and precision is low.
The utility model content
The problem that the utility model will solve is to above deficiency, provides a kind of simple in structure, and precision is high, the Digit Control Machine Tool straight line rotating shaft that moment of torsion is big.
For addressing the above problem; The utility model adopts following technical scheme: Digit Control Machine Tool straight line rotating shaft; It is characterized in that: be included in motor and nut that frame top fixedly installs, be fixedly connected with leading screw on the turning cylinder of motor, leading screw cooperates with nut; The other end of leading screw is connected with apart from the type gear, apart from type gear and gears engaged.
Further improvement as technique scheme:
Frame is provided with and is used for to carrying out spacing locating piece apart from the type gear.
The utility model adopts above technical scheme, compared with prior art, has the following advantages: the leading screw rotation drives linearly moves apart from the type gear; Apart from type gear driven gear rotation, main shaft is swung, can become rectilinear motion like this and rotatablely move; Have take up room little; Moment of torsion is big, and the characteristics that precision is high are used to add the 4th of Digit Control Machine Tool.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Accompanying drawing is the structural representation of Digit Control Machine Tool straight line rotating shaft among the utility model embodiment;
Among the figure,
1-motor, 2-nut, 3-leading screw, 4-be apart from the type gear, 5-locating piece, 6-gear, 7-milling head, 8-frame, 9-rotating shaft, 10-support.
The specific embodiment
Embodiment, as shown in the figure, Digit Control Machine Tool straight line rotating shaft, Digit Control Machine Tool comprises frame 8, and frame 8 is provided with rotating shaft 9, and rotating shaft 9 is provided with gear 6 and support 10, and support 10 is provided with milling head 7;
