Grinding method for spindle taper hole

Abstract

The invention relates to the technical field of spindle grinding, and discloses a grinding method for a spindle taper hole. The grinding method for the spindle taper hole comprises the steps that S1, a spindle swings around a Z axis of a machine tool by a preset swing angle theta 0; S2, a grinding assembly and the spindle taper hole of the spindle are subjected to tool setting, so that one generatrix on the conical surface of the spindle taper hole of the spindle is parallel to the Z axis; and S3, the spindle is driven to move up and down along the Z axis, the spindle is made to rotate along the axis of the spindle, and meanwhile a driving piece of the grinding assembly drives a grinding head to rotate so as to grind the conical surface of the spindle taper hole. According to the grinding method for the spindle taper hole, the spindle does not need to be disassembled from the numerical control machine tool, grinding of the spindle taper hole is achieved through rotation motion and up-and-down motion of the numerical control machine tool, the time for disassembling the spindle is saved, the spindle taper hole can be rapidly repaired, the working efficiency is improved, and compared with manual grinding, the maintenance precision is high, time and labor are saved, and the personal safety of operators can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of spindle grinding, in particular to a method for grinding a spindle taper hole. Background technique [0002] In the CNC machine tool, the spindle is the main tool that directly drives the tool for rotary cutting. It is a key component in the CNC machine tool and plays an important role in the normal operation of the machine tool. It is the executor of the machine tool movement and transmits Motion and torque, bearing cutting force and driving force and other loads. In the spindle, the taper hole of the spindle is the direct contact surface with the tool handle, and its fit directly affects the accuracy of the workpiece, the surface roughness of the part and the cutting efficiency of the tool. [0003] In the process of CNC machine tool processing, the spindle taper hole will inevitably suffer from different degrees of wear due to long-term use, such as rough machining of the machine tool, high cutting st...

Problems solved by technology

The disadvantage of this method is that there is no benchmark, and the judgment is based on the experience of the maintenance personnel, so the maintenance accuracy is poor, the efficiency is low, and the datum surface may be damaged due to inaccurate judgment, which cannot meet the precision requirements required for machine tool processing.

In addition, when using this method for maintenance, the operator needs to work under the main shaft, which is laborious and time-consuming, and it is difficult to guarantee personal safety
