Embodiment Construction
[0038] The present invention will be described in detail below with reference to the various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and the structural, method, or functional transformations made by those of ordinary skill in the art based on these embodiments are all included in the protection scope of the present invention.
[0039] It should be noted that when the general workpiece is not positioned in space, it has six degrees of freedom, X\Y\Z three linear displacement degrees of freedom and corresponding A\B\C three rotational displacement degrees of freedom. The six degrees of freedom are usually expressed by X\Y\Z of the Cartesian Cartesian coordinate system to express the three linear axes, and the corresponding A\B\C to express the three rotational axes. The specific directions of the x-axis, y-axis, and z-axis in this application document are defined as figure 1 The dimension direction in .

The invention discloses a CNC milling cutter end face grinding device, comprising a base, a first moving mechanism, a second moving mechanism and a numerical control system arranged on the base, a sharpening assembly and a measuring device arranged on the first moving mechanism The induction assembly, and the workpiece clamping assembly arranged on the second moving mechanism; the sharpening assembly moves along the y-axis direction under the action of the first moving mechanism, and is used for grinding the tool; the workpiece clamping assembly is located in the second moving mechanism. It moves along the x-axis direction under the action to clamp the tool; the measuring induction component includes a sensor for measuring the length of the milling cutter to be ground and a side head angular positioning head for locating the angle of the milling cutter to be ground; the numerical control system is connected to the first A moving mechanism, a sharpening assembly, a second moving mechanism, a workpiece clamping assembly and a measuring and sensing assembly are used to coordinate the linkage operation among the above components. The invention realizes high-precision numerical control grinding of milling cutters (including two-blade end mills, three-blade end mills, and four-blade end mills).
Description
technical field [0001] The invention belongs to the technical field of four-axis precision numerical control milling cutter end face grinding, and particularly relates to a numerical control milling cutter end face grinding device and a grinding method. Background technique [0002] With the development of modern manufacturing technology, the variety and demand for high-precision knives are increasing, and the performance requirements of knives are becoming more and more strict. In order to replace the low efficiency of manual grinding and obtain higher-precision knives, domestic manufacturers produce A multi-axis grinder has been developed, but the multi-axis grinder in the prior art generally has a low product grade and poor accuracy and stability, which cannot meet the customer's requirements for using high-precision tools. [0003] Therefore, in view of the above technical problems, it is necessary to provide a grinding device and a grinding method for the end face of a ...
