Description

Cutter for processing double-side chamfer of tail edge

Technical Field

The utility model relates to a cutter for machining double-side chamfer angles at the edge of a tail wing, and belongs to the technical field of machining of plate-shaped parts.

Background

In the tail fin machining process, chamfering machining of the front end and the tip of the tail fin is a complicated process in tail fin machining. The structure of the tail fin is shown in fig. 3, and is a plate-shaped part, and chamfer slopes are designed on the two sides of the edge of the front end and the tip of the tail fin. For the processing of the chamfer inclined plane, the traditional process generally needs to pad an inclined plate at the bottom of a workpiece and use an end mill to process the chamfer inclined plane, but the workpiece needs to be clamped for many times, so that the processing efficiency is low.

In addition, when the chamfer inclined surfaces at the front end and the tip of the same side face of the tail wing are machined, the straight line machining is needed to be performed by two milling cutters, a joint edge is formed at the corner part of the butt joint part of the front end and the tip of the tail wing, each part needs to be manually trimmed and removed, and the machined part of the part is easily scratched in the manual trimming and filing process. The edge state of the repaired and frustrated part is poor in consistency, the chamfer is not smooth in connection, and the front edge of the part is easy to rub with air, so that overheating phenomenon is generated.

Disclosure of Invention

The utility model aims to solve the problems of lower machining efficiency, poor consistency of the edges of parts and the like when the chamfer inclined surfaces of the front end and the tip of a tail wing are machined by the traditional process, and provides a cutter for machining double-side chamfer of the edges of the tail wing.

The utility model aims at realizing the following technical scheme:

the utility model relates to a cutter for processing double-side chamfer angles at the edge of a tail wing, which comprises a cutter bar, two groups of rotary milling cutters and locking bolts;

the front side wall of the cutter bar is provided with a milling cutter installation position, a positioning key is arranged on the milling cutter installation position, and a bolt installation screw hole is formed in the front surface of the cutter bar;

the middle part of the rotary milling cutter is a supporting ring, radially extending cutter heads are uniformly distributed on the circumference of the side wall of the supporting ring, cutting blades are arranged at the upper ends of the cutter heads along the axial direction of the supporting ring towards two sides, and the extending direction of the cutting blades is matched with the inclination angle of the chamfer inclined plane of the tail wing part to be processed; the inner wall of the rotary milling cutter supporting ring is provided with a key slot matched with a positioning key on the cutter bar milling cutter mounting position;

the two groups of rotary milling cutters are sleeved on the cutter bar milling cutter mounting position, and the front end part of the cutter bar is screwed into the locking bolt, so that the middle parts of the two groups of rotary milling cutters are axially clamped, and the included angle formed by the two opposite cutting edges of the two groups of rotary milling cutters is consistent with the angle of the chamfer inclined plane of the tail part to be processed.

A gasket is arranged between the head of the locking bolt and the front end face of the cutter bar, so that the locking bolt clamps the rotary milling cutter more reliably.

And adjusting washers are sleeved on the cutter bar milling cutter mounting positions between the two groups of rotary milling cutters, and the axial distance between the two groups of rotary milling cutters is adjusted by controlling the thickness of the adjusting washers.

Working process

When the chamfering inclined plane of the plate-shaped part is machined, after the to-be-machined tail part is clamped and fixed, then two groups of rotary milling cutters are sleeved at the machining position of the chamfering inclined plane of the to-be-machined tail part, machining of the chamfering inclined plane on two sides of the edge of the to-be-machined tail part is finished simultaneously through two groups of opposite two-side cutting edges of the rotary milling cutters, and the cutter bar is held to slide and cut along the machining area of the to-be-machined tail part under the condition that the cutter bar is perpendicular to the surface of the to-be-machined tail part, so that machining after one-time clamping can be achieved.

The beneficial effects are that: the cutter disclosed by the utility model has the advantages of simple structure, convenience in manufacturing and use, good effect in improving the machining precision, surface quality and machining efficiency of double-side chamfer angles of thin plate parts such as tail fins, and good machining effect, and avoids cutter yielding phenomenon of chamfer cutting parts caused by insufficient rigidity of workpieces. The labor intensity of operators is reduced, and the processing consistency of products is improved.
