Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, the high-low rail numerical control machine tool comprises a machine body 1, a spindle box 2, a tailstock 3 and a turret 4, wherein the spindle box 2 and the tailstock 3 are symmetrically arranged on two sides of the front end of the machine body 1 and are matched with each other, the spindle box 2 is used for clamping one end of a workpiece to be machined, the tailstock 3 is used for supporting the other end of the workpiece against the support to prevent the workpiece from falling off, and the turret 4 is obliquely arranged behind the machine body 1, so that the cutter is converted and can move to contact with the surface of the workpiece to realize cutting when the workpiece rotates at a high speed.

The rear of the lathe bed 1 is provided with a high step 5, namely the front is a high step behind the low step, the upper end surface of the high step 5 is of a horizontal plane structure and is fixed with a guide rail 6, the guide rails 6 on the high step 5 and the low step 5 are arranged along the transverse direction of the lathe bed 1 and are parallel to each other, a slide block 7 is horizontally arranged on the guide rail 6, the slide block 7 can translate on the guide rail 6, a large supporting plate 8 is fixed on the slide block 7, the bottom surface structure of the large supporting plate 8 is matched with the fall of the high step 5 and the low step 5, namely the fall of the bottom surface of the large supporting plate 8 is the same as the fall of the high step 5, the upper surface of the large supporting plate 8 is of an inclined plane structure, a small dragging plate 9 is arranged on the large supporting plate 8, and the turret 4 is fixed on the small dragging plate 9.

The principle of the high-low rail numerical control machine tool is as follows: it is fixed to pass through headstock 2 with the one end of work piece during processing, the other end supports through tailstock 3 and leans on fixedly, headstock 2 drives the high-speed rotation of work piece, 8 little plankers of cooperation of big layer board 8 this moment make turret 4 remove to setting for the position, its moving means is the operation of motor cooperation lead screw 10, thereby turret 4 realizes the processing to the work piece through rotatory cutter and the work piece surface contact that makes the settlement, in this design, a guide rail 6 for bearing big layer board 8 is the level setting, cooperate the structure of height step 5 and the 8 bottom surfaces of big layer board simultaneously, make guide rail 6 realize perpendicular atress, difficult wearing and tearing life is longer between guide rail 6 and slider 7 in the in-service use.

Further, a screw rod 10 is arranged between the fall surfaces of the high and low steps 5 on the bed body 1, the screw rod 10 is connected with the large supporting plate 8, and equivalently, the screw rod 10 is arranged in the middle of the large supporting plate 8, so that the screw rod is stressed more uniformly during translation, and meanwhile, the space at the position is effectively utilized, so that the structure is more compact.
