Self-propelled type end cutter with smoothing blade

Abstract

The invention discloses a self-propelled rotary face milling cutter with a slicking blade, comprising a cutter body, a tool apron slot, a cutting tool apron, a slicking tool apron, a positioning surface, a bearing, a cutting blade and a slicking blade. The cutter body is in an odd-number five-slot shape. The tool apron comprises the cutting tool apron and the slicking tool apron. The cutting tool apron utilizes a cutter shaft supporting structure of combining the angular contact bearing and the composite bearing. The slicking tool apron utilizes a cutter supporting structure of combing enclasping up-and-down sliding bearing ring and the composite bearing. The tool apron slot utilizes an over-positioning structure of repeated limiting of the conical surface and the planar surface, and the tool apron slot inclines in both axial direction and the radial direction, so as to enable the self-rotary blade to obtain the cutting edge inclination angle and ensure the continuous self-rotation during processing. The blade utilizes a tangential structure. The slicking blade finally finishes processing the surface. The milling cutter has the advantages of reasonable design, compact structure, good cutting performance, fast cutting speed and high processing precision. The milling cutter also has the advantages that the cutting speed is increased by 50%, the processing precision is improved by 1-2 levels, the surface roughness is up to Ra0.8 micrometers, cooling lubricant is replaced by drying milling, environmental pollution is avoided, and the cutting and slicking functions complement with each other.

[0002] In mechanical processing, metal cutting tools are very important. In aerospace, aviation and military industries, there are more and more difficult-to-machine materials, and the requirements for metal cutting tools are getting higher and higher. Due to the high cutting temperature and fast tool wear, Often use cooling lubricating fluid, which not only increases the cost, but also brings pollution

[0003] Among cutting tools, milling cutters are one of the most commonly used machining tools, especially end face and plane milling tools are more common. Due to the large amount of plane milling of mechanical parts, the consumption of tools is very large and the milling speed is low. , the milling quality is poor, which prompts people to improve the structure of milling tools, but there are still many deficiencies in the existing technology, and there are many things that need to be improved and discussed in terms of tool structure, angle and cutting performance.

[0004] For example: 8721546.7, the patent of hobbing end milling cutter, the blade inclination angle of the vertically mounted structure tool is adjustable, and the radial position of the tool holder is adjustable, but the tool structure is difficult to ensure that the axial height of each blade is consistent with the blade inclination angle, which directly affects the processing of the tool Quality and precision, the blade is vertically mounted with a complex double support structure, it is extremely inconvenient to replace the blade, the design of the flat structure of the blade is unreasonable, and the blade cannot be rotated during processing

[0005] For example: 02210332.5, self-rolling cutting end mill patent, 3-18 rolling devices are evenly distributed around the cutter body, and the radial deflection angle of the blade is 8°-28° to ensure the continuous rotation of the blade during processing, but due to the The radial and axial positions of the blades are fixed, but the blade diameter error and the position error of the mounting hole make the height of 3-18 blades inconsistent in the axial direction, resulting in low milling accuracy and poor surface roughness
