Gantry vertical honing machine

Abstract

The invention discloses a portal type vertical honing machine, comprising a rack, a radial feeding mechanism, an axial feeding mechanism, a grinding mechanism and a control system, wherein the grinding mechanism comprises a driving mechanism and a grinding head; the driving mechanism can drive the grinding head to rotatably grind; the control system can control the axial feeding mechanism, the radial feeding mechanism and the driving mechanism to move; the rack comprises two stand columns and a cross beam; the cross beam can be vertically positioned between the two stand columns in a sliding manner; the axial feeding mechanism is fixedly positioned on the stand columns; the axial feeding mechanism can drive the cross beam to vertically move; the radial feeding mechanism is fixedly positioned on the cross beam; the grinding mechanism is axially locked and positioned on the cross beam; and the radial feeding mechanism can drive the grinding mechanism to slide along the length direction of the cross beam. According to the portal type vertical honing machine provided by the invention, the axis of the grinding head and the rack are collinear; and a moment is not generated between the grinding head and the rack in a working process, so that the rigidity is greatly enhanced, the grinding head is prevented from axially swing, and the machining precision can be improved.

Description

technical field [0001] The invention relates to a honing machine, in particular to a gantry vertical honing machine. Background technique [0002] Honing is a process of finely grinding the surface of the product through the abrasive bar on the surface of the grinding head. It is usually used to grind cylindrical holes. Of course, it can also grind planes, outer circles, spherical surfaces and teeth. Commonly used vertical honing machines are The grinding head protrudes out of the frame, so that the grinding head and the frame are not collinear, and torque will be generated during the working process, which reduces the rigidity of the grinding head, and easily causes the axis of the grinding head to deflect, resulting in low grinding accuracy , it is difficult to meet the high-precision processing of large apertures. At present, horizontal honing machines are commonly used for processing by boring and grinding. However, the problem with this processing method is that the gri...
