Description

A 90 degree chamfering cutter head

technical field

The invention relates to the technical field of cutting blades, in particular to a 90-degree chamfering cutterhead.

Background technique

Based on the requirements of the installation process, it is often necessary to chamfer the parts. In addition, chamfering also has the function of removing burrs. Therefore, even if there is no installation process requirement, in order to make the appearance of parts or products more beautiful, the right-angled edges are often chamfered. When machining the shape of most parts or products, it is usually necessary to chamfer the two parallel silhouette edges. The traditional processing method is to use the chamfering cutter grain to process the two silhouette edges sequentially. Although this method can complete The chamfering process of the product, but the processing time is long and the efficiency is low. If the cutter grains used for the chamfering of the two contour edges are inconsistent, it is necessary to replace the cutter grains, which increases the preparation time for processing and reduces the processing efficiency. will be lower.

detailed description

The present invention will be described below in conjunction with specific embodiments.

As shown in Figure 1-3, a 90-degree chamfering cutterhead includes a cutterhead main body 1, and the upper end of the cutterhead main body 1 is provided with a central stopper in the middle that is circular inside and equilateral outside. 11. A number of knife grain installation cavities 12 arranged in a ring shape and knife grain limit bosses 13 corresponding to the number of knife grain installation cavities 12 and arranged in a ring shape. The upper end of the knife grain installation cavity 12 is equipped with a knife position block 21. The upper end of the knife position block 21 is provided with a knife position groove 22, the upper end of the knife position groove 22 is equipped with a knife grain 2, the side end of the knife grain 2 is equipped with a knife grain pressing block 23, and the lower end of the knife grain pressing block 23 is provided with A hook-shaped pressing block boss 231 is mounted on the bottom of the knife grain 2 .

As preferred in this embodiment, the upper end of the cutterhead main body 1 is provided with a central stopper 11 which is circular in the inside and hexagonal in the outside.

As preferred in this embodiment, the upper end of the cutterhead main body 1 is provided with six cutter particle mounting cavities 12 arranged in a ring shape and a number of cutter particle limiting bosses arranged in a ring shape corresponding to the cutter particle mounting cavities 12 13.

Further, the cutter grain pressing block 23 is mounted on the upper end of the cutter head main body 1 through the forward and reverse screws 232 .
