TECHNICAL FIELD
[0001] The present application relates to the technical field of machining, in particular to the technical field of a composite machining machine tool with a turning structure. BACKGROUND
[0002] A machine tool is a device used for machining various metals, non-metals and other materials to make parts, components or products; a screw generally adopts a traditional lathe tool feed to be changed into a milling tool feed structure, but the screw has the characteristics of relatively long length and relatively thin diameter, and the existing screw machining machine tool has a certain bending deformation and a large machining error when machining a relatively long and thin screw due to the cutting force of the cutting tool and the weight of the screw itself.
[0003] To solve the problems in the above-mentioned technology, for example, application No. CN201420281188.7 discloses a long screw machining machine tool, which comprises a machine base, a machine box, a cutting tool feed mechanism and a fixed top pin mechanism, characterized in that: the cutting tool feed mechanism is connected with a support structure through a guide rod on the side, the support structure comprises a bottom plate and a V-shaped support plate arranged on the bottom plate, the bottom plate is arranged on the machine base through a track structure, height-adjustable support structures are arranged on both sides of the cutting tool feed mechanism, and the support structures are used to offset the deformation caused by the cutting force and the weight of the long screw, thereby effectively avoiding the bending deformation of the long screw during machining and improving the machining precision of the screw.
[0004] However, the above-mentioned device produces a large amount of iron filings accumulated at the bottom of the machining table when fine polishing the screw, and the front cover of the machine tool needs to be opened regularly to clean it with a special tool, which is relatively cumbersome.
