Abstract

The invention discloses a spherical coordinates boring machine, comprising a spherical coordinate device, two or more clamps and a tool assembly; each clamp comprises a hydraulic cylinder, a piston and a plurality of piston rods; the hydraulic cylinder is movably disposed on a circular graduated disc, the cylinder cover of the hydraulic cylinder is provided with a plurality of first piston rod through holes, the piston is disposed in the hydraulic cylinder and can reciprocate in the hydraulic cylinder, a plurality of second piston rod through holes are formed in the piston; the upper ends of the plurality of piston rods exceed the upper side of the piston and extend inwards the hydraulic cylinder, and the lower ends extend outside the cylinder cover of the hydraulic cylinder and are fit with a workpiece. The clamps used in the spherical coordinates boring machine disclosed by the invention comprise a plurality of piston rods in contact with the workpiece, the piston and the small piston rod with a boss at one end can stretch out independently and retract together, the clamps are free from the limit of the surface shape of the workpiece, in addition, the clamping requirements of approaching workpiece automatically and fast, clamping slowly, and loading and unloading rapidly are met by hydraulic control.

Description

Technical field [0001] The invention relates to a workpiece processing mechanical equipment, in particular to a spherical coordinate drilling machine. Background technique [0002] When drilling, tapping or other processing on a spherical workpiece, it is not easy to clamp the spherical workpiece without a special fixture. The processing of thin-walled parts has always been difficult to solve. The reason is that thin-walled parts have poor rigidity and weak strength, and are easily deformed in the middle of processing, and it is not easy to ensure the processing quality of the parts. There are many factors that affect the accuracy of thin-walled parts, but they can be summed up mainly in the following three aspects: (1) Forced deformation, due to the thin wall of the workpiece, it is easy to deform under the action of clamping force, which affects the dimensional accuracy and Shape accuracy. (2) Thermal deformation, because the workpiece is thin, the heat of cutting will cause...
