Twin surface grinder

Abstract

The invention provides a twin surface grinder which comprises a grinder body, a wheel dresser assembly and a feeding assembly as well as a spindle, a spindle assembly, a grinding wheel, a spindle motor, a motor group and a threaded shaft which are positioned on the grinder body, wherein the grinding wheel is installed at one end of the spindle, the shell of the wheel dresser assembly is integrated with a dust shield to protect the grinding wheel, the spindle assembly is installed on the spindle, one end of the threaded shaft is connected with the motor group, the threaded shaft is connected with the spindle assembly, the motor group controls the threaded shaft to rotate, the threaded shaft drives the spindle assembly to move left and right so as to realize the feeding movement in the grinding process, and the spindle motor is used for driving the grinding wheel and the spindle to rotate so as to realize the grinding movement. By using the technical scheme provided by the invention, the feeding movement of the grinder is converted to the straight-line feeding displacement of the grinder by the reducer and the nut threaded shaft under the rotation effect of a PLC or numerical control stepping motor, and the invention has characteristics of simple control, visual display, precise movement, high feeding resolution and the like.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to a double-end surface grinding machine. Background technique [0002] The grinding machine is used for high-precision fields such as two-plane grinding of bearings, connecting rods, air conditioners, etc. It is widely used in industry. The basic structure types of existing double-end grinding machines include V-shaped guide rails, needle roller guide rails, and ball guide rails, and the sliding seat slides on the guide rails fixed on the bed. Due to the gap between the sliding seat and the guide rail and the poor adjustability of the clamping device, the accuracy is low and the feed resolution is low. The double-end grinding machine needs to have poor rigidity, large clearance, insufficient stability, unstable hydraulic pressure, and high temperature requirements. When the temperature increases during use, the grinding machine will drop. [0003] Therefore, during the...

Problems solved by technology

Due to the gap between the slide seat and the guide rail and the poor adjustability of the clamping device, the accuracy is low and the feed resolution is low

The double-end grinding machine needs to have poor rigidity, large clearance, insufficient stability, unstable hydraulic pressure, and high temperature requirements. When the temperature increases during use, the grinding machine will drop.

[0003] Therefore, during the creation process of the present invention, the inventors found that there are at least the following problems in the prior art: the existing double-end grinding machine has low precision, low feed resolution, poor rigidity, and easy wear
