Embodiment Construction

[0036] Below, specific embodiments of the present invention will be described in detail in conjunction with the accompanying drawings, but they are not intended to limit the present invention.

[0037] It should be understood that various modifications may be made to the embodiments disclosed herein. Accordingly, the above description should not be viewed as limiting, but only as exemplifications of embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the disclosure.

[0038] Since the vertical double-surface grinder has two spindle assemblies arranged symmetrically, the spindle feeding device of the double-surface grinder in the embodiment of the present invention includes two feed units symmetrically arranged, and the two feed units are respectively applied to the symmetrically arranged of the two spindle assemblies.

[0039] Next, take one of the feeding units as an example to describe in detail.

[0040] like Figure 1-...

Abstract

The invention relates to the technical field of numerical control machine tools, in particular to a spindle feeding device of a double-surface grinding machine. The spindle feeding device of the double-surface grinding machine comprises two feeding units which are symmetrically arranged, wherein the two feeding units are correspondingly applied to two spindle assemblies which are symmetrically arranged; the feeding units comprise box bodies and screw rod parts, wherein first fixing sleeves and second fixing sleeves which are coaxial with the spindle assemblies are arranged in the box bodies, the spindle assemblies movably penetrate through the first fixing sleeves and the second fixing sleeves, the first ends of the spindle assemblies extend out of the first fixing sleeves, and the secondends of the spindle assemblies extend out of the second fixing sleeves; and the screw rod parts are connected with the spindle assemblies through screw rod seats, the screw rod parts are connected with servo motors, and the servo motors drive the spindle assemblies to move in the axial direction of the spindle assemblies through the screw rod parts. According to the spindle feeding device of the double-surface grinding machine, the fixing sleeves coaxial with the spindle assemblies can play the role of sliding guide rails, so that the rigidity and the feeding precision of the spindle assemblies are improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of numerical control machine tools, in particular to a spindle feed device for a double-surface grinding machine. Background technique [0002] The vertical grinding machine in the prior art is usually provided with a fixed column, and a spindle box containing a spindle assembly is arranged outside the fixed column. Its screw nut is connected with the spindle box, and the screw rod can be driven to rotate by the servo motor, so that the spindle box makes a linear feed motion on the guide rail through the slide block in the linear guide pair along with the screw nut. [0003] The combination of ball nut and ball screw is a commonly used linear feed movement method. By rotating the screw, the screw nut moves linearly, or by rotating the screw nut, the screw produces linear motion. Regardless of the precise fit between the screw nut and the screw rod, there will always be a gap. Even ...
