Background
Turning is a method of machining, and mainly uses turning tools to machine a rotating workpiece, wherein the turning tools are arranged on a tool rest, an inner protective cover slides along a tool body to drive the tool rest to slide along the tool body, and the turning tools do cutting machining of linear or curved movement in a plane. Lathes are used primarily for machining shafts, discs, sleeves and other workpieces having surfaces of revolution, and are the most widely used type of machine tool in machinery manufacturing and repair facilities.
In order to prevent scraps generated in the machining process from splashing outside the lathe, an outer protective cover is fixed on the lathe body of the lathe; in order to prevent scraps from splashing on all parts in the lathe, an inner protective cover is arranged in the outer protective cover. At present, a ball screw structure is generally adopted to drive a cutter to move, the cutter is fixed with a nut seat of the ball screw structure, and a motor drives a screw rod of the ball screw structure to rotate forwards or reversely so as to enable the cutter to move reciprocally.
During machining, the tool is moved to turn different parts of the workpiece. The tool rotates during turning, the tool continuously vibrates in the workpiece machining process, and the tool rest and the inner protective cover vibrate when the tool vibrates because the tool is fixed on the tool rest and the tool rest is fixed with the inner protective cover. When the inner protective cover vibrates, gaps appear between the inner protective cover and the tool rest or between the inner protective cover and the lathe bed, scraps generated in the turning process easily enter the lathe from the gaps and finally fall onto a screw rod of the ball screw structure, the scraps can obstruct the sliding of a nut seat of the ball screw structure, movement of a tool is blocked finally, the movement distance and the precision of the tool are affected, and the machining precision of a workpiece is low.
