Description

CNC lathe with pad mounted ball screw

technical field

The utility model relates to the technical field of machining, in particular to a numerically controlled lathe with a pad mounted ball screw.

Background technique

On a common machine tool, it includes a main shaft that fixes the workpiece and drives it to rotate, and a linear drive motor that pushes the tool to do reciprocating feed motion, so that relative motion can occur between the workpiece and the tool for machining the workpiece. Among the row-cutter CNC machining machines used, the machining accuracy of the CNC machining machine is not high, and its linear drive motor will be offset under the action of continuous radial compressive stress, which will significantly reduce the machining accuracy of the workpiece, and The service life of the parts will also be greatly reduced. At the same time, the linear drive motor is originally not high in precision, and it runs unstable and shakes, which cannot meet the high-precision processing requirements.

Moreover, the movable end of the linear drive motor is fixedly connected with a carriage.

Preferably, a base is provided at the lower end of the bed.

Preferably, the section of the slide rail is U-shaped.

Preferably, both sides of the slider A are provided with bumps, and the gap between the bumps and the slide rail is filled with friction pads, and the friction pads are fixedly connected to the slide rails through screws.

Preferably, the upper end surface of the bed is inclined.

Preferably, a row of knives is fixedly installed on the carriage.

Compared with the prior art, the beneficial effect of the utility model is that: the numerically controlled lathe with the ball screw mounted on the mat is equipped with a ball screw, and the ball screw is driven by a servo motor, which can greatly improve the sliding smoothness of the skateboard, and the ball The screw has very small friction resistance, and the transmission efficiency of the ball screw is high, the service life is long, and it can be used for micro-feed and high-speed feed, which can process workpieces in large quantities and ensure the overall accuracy of the workpiece. The lower end of the block A is equipped with a slide rail, which can be replaced, and a friction gasket is fixedly installed on the slide rail. The friction gasket can be replaced frequently to reduce maintenance costs. At the same time, there are line rails and slider B. The slider B can slide along the two line rails, which can avoid the sliding plate from shaking back and forth during the processing, making the processing more stable and improving the processing accuracy.
