Problems solved by technology

The transfer of the machining center to the honing machine requires secondary clamping and positioning of the workpiece. Repeated clamping between processes will cause cumulative errors, which directly affects the control of machining accuracy indicators related to the inner holes of precision parts, and repositioning also affects processing efficiency.

Abstract

The invention provides a honing machining center. The honing machining center has two kinds, one kind comprises a built-in feeding mechanism, and the other kind comprises an external feeding mechanism. According to the honing machining center, before the honing machining center is used, cutting tools and honing heads are located inside a tool magazine, when honing operations need to be performed, one honing head is transferred from the tool magazine to a main shaft component by a cutting tool changing device, by doing so, the machining center can automatically replace and install ordinary cutting tools and also can automatically replace and install the honing heads to make the machining center have the function of replacing the honing heads directly after fine boring is finished, repeated positioning of workpieces is not needed, the processes of the repeated positioning and clamping of machined parts are reduced, the geometric accuracy and the inner hole surface roughness of the machined parts are improved, and the production efficiency is improved; meanwhile, the machining center can select the honing heads of different models from the tool magazine, and rough-honing and fine-honing machining of inner holes of different diameters can be finished; and in addition, the honing heads are provided with plug gauge measuring heads, the size accuracy of the workpieces is made to reach the range of being less than or equal to 0.01, and the roughness value of the parts is made to reach the range of being less than or equal to Ra0.1.

Description

technical field [0001] The invention relates to the technical field of precision inner hole machining, in particular to a honing machining center. Background technique [0002] Industrial robot RV reducer needle roller bearing holes, high-precision hydraulic valve body holes and other precision hole system parts have high requirements for dimensional accuracy, geometric accuracy, position, verticality, and surface roughness, and even need to process reticulated grooves Groove for oil reservoir lubrication. The prior art is to adopt the machining center to complete operations such as drilling, enlarging, boring, and reaming of the precision inner hole parts, and then carry out the honing process of the precision inner hole on the honing machine tool. The structure of the machining center in the prior art includes a base, a workbench, a column, a spindle box, a spindle component, a tool magazine, a tool handle, a tool changing device, a numerical control system, an electric c...
