Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The utility model provides a technical scheme: the utility model provides a double-spindle lathe, includes base 1, the position that lies in the centre on base 1 is provided with blade holder 2, and is provided with about two mutually independent processing portions 3 about blade holder 2 symmetry on base 1, and arbitrary one of two processing portions 3 is sent to blade holder 2 after the work piece centre gripping earlier and is carried out one of them surface machining of work piece to give another processing portion 3 processing with the work piece, and send the work piece to blade holder 2 by another processing portion 3 and go up another surface processing.

In the embodiment, one of the processing parts 3 is processed first, the processed semi-finished workpiece is moved to the butt joint position, and the processed semi-finished workpiece is transferred to the other processing part 3 which is also moved to the butt joint position, so that the butt joint of parts is realized, an external manipulator is not needed, the cost of a machine tool is saved, and meanwhile, the workpieces are directly butt-jointed and transferred by the two processing parts 3, so that the time is saved.

Further, the machining section 3 includes a jig 31 for clamping the workpiece, and the jig 31 is provided in a three-jaw chuck type.

In the present embodiment, the clamp 31 is configured as a three-jaw chuck to conveniently clamp a cylindrical workpiece, and firmly convey the workpiece clamp to the tool bit, so that the tool bit performs a cutting operation, thereby realizing rapid and precise processing of the workpiece.

Further, the clamp 31 is installed on an electric spindle 32, and the electric spindle 32 is composed of a motor, a coupler and a rotating rod.

In this embodiment, the motor drives the rotating rod to rotate through the coupler, the rotating rod drives the front end clamp 31 to rotate, and the clamp 31 rotates to drive the workpiece clamped by the clamp to rotate, so that the workpiece is rotatably cut on the cutter, and the workpiece is machined.

Further, the electric spindle 32 is mounted on a first moving part 33 capable of moving transversely, the first moving part 33 is mounted on a second moving part 34 capable of moving longitudinally, and the second moving part 34 is mounted on the base 1; the first moving portion 33 and the second moving portion 34 each include a slide groove, an electric screw accommodated in the slide groove, and a slide base moved along the slide groove by the electric screw.
