Description

Woodworking profiling milling cutter for processing decorative strip

Technical Field

The utility model relates to a cutter technique, especially woodworking tool, specifically are carpenter's profile milling cutter for processing ornamental strip.

Background

At present, in woodworking tools, when decorative strips on door leaves and cabinet surfaces are machined, profile milling cutters are mostly used as the used tools. The profile milling cutter is a special cutter designed according to the surface shape requirement of an object to be processed, the contour of a cutting edge of the profile milling cutter corresponds to the contour of the surface of the object after the object is processed, the cutter is convenient to use, the processed surface has good quality, but the cutter is high in overall cost, the cutting edge cannot be ground for multiple times, so that the front shape and the rear shape are not consistent, and the service life of the cutter is short.

The types of the decoration strips in woodwork are various, and each decoration strip needs to be correspondingly provided with a profile milling cutter. For manufacturers specialized in producing the wood decorative strips, the used cutters are various and large in consumption. However, in the prior art, the profile milling cutter is an integrated cutter, and once the profile cutting edge is damaged, the cutter handle becomes waste, so that the profile milling cutter with low use cost is designed to be welcomed by users.

Disclosure of Invention

To the problem in the background art, the utility model aims at providing a carpenter's profile modeling milling cutter for processing ornamental strip, the cutter adopts split type design, and the profile modeling tool bit is removable, and handle of a knife repeatedly usable can effectively reduce the use cost of cutter.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a woodworking profiling milling cutter for machining decorative strips comprises a cutter handle, a positioning boss, a positioning shaft, a positioning key and a profiling cutter head, wherein the whole cutter handle is of a cylindrical structure, the lower end of the cutter handle is coaxially provided with the disc-shaped positioning boss, the middle of the positioning boss is coaxially provided with the positioning shaft, and the lower end of the outer cylindrical surface of the positioning boss is equally provided with key grooves A; the profiling cutter head comprises a cutter body and blades, the upper part of the cutter body is sleeved on the positioning shaft, the lower end of the cutter body is provided with a chip groove in an equal part mode, one side wall of the chip groove is welded with the blades, and the upper end of the cutter body is provided with key grooves C in an equal part mode corresponding to the key grooves A on the positioning boss; and a positioning key is arranged in the key groove C and is fixedly connected with the corresponding key groove A through the positioning key.

The number of the key grooves A is at least two.

The number of the chip grooves of the cutter body is the same as that of the key grooves A.

The diameter of the positioning boss is smaller than or equal to the cutting diameter of the copying tool bit.

The lower part of the outer cylindrical surface of the knife handle is also provided with an annular boss which is fixed into a whole, a guide bearing is sleeved on the knife handle at the upper part of the annular boss, and the guide bearing is tightly pressed on the annular boss through a screw cap.

The utility model has the advantages that: the utility model discloses a handle of a knife repeatedly usable, direction bearing can dispose according to the diameter of cutter body, and the copying tool bit adopts the welding blade, damages when the blade, also can come used repeatedly copying tool bit through changing the blade.
