Machining center machine tool and machining method specially for horizontal type bolted sphere

Abstract

The invention discloses a machining center machine tool and machining method specially for a horizontal type bolted sphere. The machining center machine tool and machining method specially for the horizontal type bolted sphere comprises a cross side way, a horizontal sliding table, a longitudinal sliding table, a base, and a horizontal type circular tool magazine; and the cross side way is arranged on the plane of the base and is provided with the horizontal sliding table, the longitudinal sliding table is arranged on the upper end of the horizontal sliding table, the horizontal type circulartool magazine is arranged at one end of the longitudinal sliding table and is characterized by comprising a four-axis feed system and a tool changing system, and the four-axis feed system comprises aturntable system, a horizontal sliding table, and a longitudinal sliding table. The main design is the sphere center of the bolted sphere being a machining benchmark, without or reducing fixture changing, each of error factors caused by an unfixed sphere center is eliminated, machining accuracy is enhanced significantly, the sensibility of an initial position during machining is reduced, force isuniform and reliable, and rigid maintenance performance is good; and the sphere center of the bolted sphere is a reliable functional unit for design and modifying of a horizontal type machine tool ofthe bolted sphere.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a machine tool and a processing method of a horizontal bolt ball special machining center. Background technique [0002] Bolt ball processing is usually carried out by modifying the tool post of ordinary lathe. Due to the large hole shape of the bolt ball and the heavy processing load, the drilling force exceeds 1 ton under the condition of processing large holes, and the tapping torque exceeds 2000 Nm. Only large-scale 5-axis machining centers can be used to process bolt balls. Regardless of accuracy or efficiency, the industry's cost is unacceptable. Therefore, the main problem is to design and develop a special processing machine tool for bolt balls that can withstand the processing load of bolt balls, has high precision, fewer axes, and low cost. Contents of the invention [0003] The present invention aims to solve one of the technical problems in ...
