Lathing and grinding integrated numerically-controlled machine tool for machining circular workpiece

Abstract

The invention belongs to the field of numerically-controlled machine tools, and particularly relates to a lathing and grinding integrated numerically-controlled machine tool for machining circular workpieces. The lathing and grinding integrated numerically-controlled machine tool comprises a base, a stand column, a spindle box, a tool magazine and a spindle. The spindle box and the tool magazine are arranged on the stand column, the spindle is arranged on the spindle box, a clamping component is arranged at the bottom of the spindle, a tool-changing mechanism is arranged on the tool magazine, a vertical linear rail and a vertical sliding seat sliding along the vertical linear rail are arranged on the base, a horizontal linear rail is arranged on the vertical sliding seat, a support frame is arranged on the horizontal linear rail, the support frame is provided with a rotary spindle, a workpiece holder and a motor, the workpiece holder is fixedly arranged at the top of the rotary spindle, the motor is connected with the bottom of the rotary spindle, and a tool inside the tool magazine comprises a lathing tool and a grinding head. Due to the fact that the lathing tool and the grinding head are directly arranged on the numerically-controlled machine tool and one-step rapid forming of the circular workpieces in one equipment is realized in a manner that the workpiece rotates automatically at a high speed and the tool only moves vertically and horizontally, machining efficiency is improved, and machining cost is saved. Besides, a finished product machined is high in glossiness.

Description

technical field [0001] The invention belongs to the field of numerical control machine tools, and in particular relates to a turning and grinding integrated numerical control machine tool for processing circular workpieces. Background technique [0002] The processing of existing circular workpieces (such as cups, bowls, plates or cylindrical workpieces) needs to be processed through two sets of equipment and two processes, that is, it is first turned on a lathe and then sent to a grinder for grinding. Processing is troublesome and the workpiece requires Two times of clamping, the concentricity and roundness of the processed finished product are poor, the two sets of equipment of lathe and grinder are complicated, and the processing cost is high. Moreover, the existing round workpiece processing method is fixed-point workpiece, and the cutter head or grinding head rotates around the processing surface of the workpiece under the rotation of the main shaft. Since the main shaf...

[0002] The processing of existing circular workpieces (such as cups, bowls, plates or cylindrical workpieces) needs to be processed through two sets of equipment and two processes, that is, it is first turned on a lathe and then sent to a grinder for grinding. Processing is troublesome and the workpiece requires Two times of clamping, the concentricity and roundness of the processed finished product are poor, the two sets of equipment of lathe and grinder are complicated, and the processing cost is high

Moreover, the existing round workpiece processing method is fixed-point workpiece, and the cutter head or grinding head rotates around the processing surface of the workpiece under the rotation of the main shaft. Since the main shaft moves slowly in a circle, the processing time is long , the processing efficiency is low, and the regularity and smoothness of the finished product are poor
