Five-shaft cutter grinding machine

Abstract

A five-shaft cutter grinding machine comprises a steel frame base, a filtering water tank, a platform, an X shaft, a precision rotary shaft, a cutter bar stock supporting frame, a Y shaft, a main shaft, a grinding wheel set, a rotary shaft, a stand column, a Z shaft, a bar stock far-end supporting module and a nozzle. Compared with most products of the same type abroad where the technologies like servomotor driving and worm and gear drive are adopted, the precise rotary shaft adopted in the five-shaft cutter grinding machine is driven by a direct driving type motor, does not need the intermediate transmission link, and has higher movement speed. Particularly, the intermediate transmission link does need to be used for transmitting movement, so that rotation gaps generated by a worm and gear transmission mechanism and other transmission mechanisms are completely eliminated. The five-shaft cutter grinding machine has the advantages that the rotation speed is high, waterproof sealing is achieved, the cutter bar stock automatic clamping function is achieved, precision is high, the structure is compact, and the grinding machine is modularized. Therefore, a comprehensive optimized solution is provided for cutter precise machining.

Description

technical field [0001] The invention relates to a processing device, in particular to a five-axis tool grinding machine. Background technique [0002] As a professional tool for CNC machine tools to process precision parts, cutting tools directly determine the precision of the precision parts processed by them.

Problems solved by technology

[0003] Traditional tool grinding machines used for tool processing or tool grinding are all designed with an integral structure layout and shaft system, that is, the shaft system is integrated with the machine bed, column, etc., and its Y-axis is directly connected to the machine bed. As the base, the Z-axis uses the column as the base, the X-axis is directly installed on the Y-axis through the workbench, and the column equipped with the Z-axis will be fixed on the bed in the second half of the Y-axis. X, Y, and Z are vertically arranged, and the upper rotation axis B and the rotation axis C are configured, thus forming a typical five-axis (X, Y, Z, B, C) linkage tool grinder, and the grinding wheel set is independently provided by the main shaft. Because the tool has complex structural features such as rake angle and relief angle, in order to meet its processing needs, the five-axis tool grinder needs to have multi-degree-of-freedom movement capabilities, and these degrees of freedom are all through the linear axis ( X-axis, Y-axis, Z-axis), rotary axis (B-axis and C-axis), the motion control is carried out through the numerical control system, and various spatial motion states are provided for the spindle installed at the output end of the rotary axis B, which is convenient for installation on the spindle The grinding wheel group at the end selects the appropriate spatial attitude to process the tool, and finally processes various tools; for a long time, the five-axis tool grinder has been a hot spot in the research of CNC machine tools due to its complex shaft system structure and control technology. Among them, the shaft system, especially the precision rotating shaft, has become the key to the design of the grinding machine. It is relatively easy to realize the design of the linear shaft in the domestic grinding machine equipment, but the precision rotating shaft is almost completely imported due to its complex structure and high performance requirements.
