Automatic numerical control machine tool for bolt production

Abstract

The invention discloses an automatic numerical control machine tool for bolt production, and relates to the technical field of automatic production. The automatic numerical control machine tool for bolt production comprises a bottom plate, a lifting clamp and a mounting frame are fixed to the top of the bottom plate, and a driving motor is fixed to the top of the inner side of the mounting frame. According to the automatic numerical control machine tool for bolt production, in the forward rotation cutting process of a machining device, an auxiliary channel can suck air outside the machining device and then convey the sucked air to the inner side of the machining device, so that air circulation of the inner side of the machining device is improved, and the temperature of a bolt and a machining cutting tool bit is effectively reduced. When the machining device rotates reversely to enable the machining cutting tool bit to be separated from the bolt, the machining cutting tool bit can push out scrap iron in the threads, and mutual movement between air outside the machining device and air inside the auxiliary channel can enable the interior of the auxiliary channel to be in a certain negative pressure state, so that the scrap iron is separated from the machining device through the auxiliary channel.

Description

technical field [0001] The invention relates to the technical field of automatic production, in particular to an automatic numerical control machine tool for bolt production. Background technique [0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. The existing bolts with high precision requirements are generally produced automatically by CNC machine tools and used on CNC machine tools. A rotatable cutter cuts the steel cylinder such that threads are cut out of the steel cylinder sidewall. [0003] However, after the existing bolt production machine tools are produced, some iron filings will remain in the thread depres...

AI Technical Summary

Problems solved by technology

[0003] However, after the existing bolt production machine tools are produced, some iron filings will remain in the thread depressions on the surface of the bolts, which will have a certain impact on the use of the bolts. At the same time, during the bolt production process, the friction between the cutter and the bolts It will increase the temperature of the cutter, which will easily cause damage to the cutter and unqualified bolt production, and there are certain defects.
