Problems solved by technology

[0003] Milling cutters are widely used in milling. The existing milling cutters usually consist of a cutter body and a blade fixed on the fixed part of the cutter body. After a period of use, the blade will become shorter due to wear and cannot continue to be used.
Therefore, in milling, it is necessary to frequently replace the blades that are shortened due to wear, so that the cost of tool usage increases sharply
[0004] In addition, the existing milling cutters generally do not have the function of collecting debris generated during the milling process, and the tool holder is not firmly clamped on the clamping device and is easy to shake, resulting in reduced machining accuracy

Abstract

The invention discloses a stably clamped milling cutter which is characterized by comprising a cutter bar (1), a cutter head (2) and blades (3), wherein the cutter head (2) coaxial with the cutter bar (1) is arranged at the upper end of the cutter bar (1); the blades (3) are arranged on the cutter head (2); a milling part (4) which protrudes out of the cutter head (2) is arranged at the front end of the blades (3); strip-shaped holes (5) which penetrate through the blades (3) are formed in the middle rear parts of the blades (3); a bolt (6) fixed on the cutter head (2) penetrates through the strip-shaped holes (5) and is fixed by a nut (7); and an annular groove (9) through which the cutter bar (1) is conveniently clamped is formed in the cutter bar (1). The stably clamped milling cutter provided by the invention is simple in structure, reasonable in design and stable to clamp and has a scrap collection function, the length of the blades is adjustable, the service life of the blades is prolonged, and the production cost is reduced.

Description

technical field [0001] The invention relates to a stably clamped milling cutter, which belongs to the technical field of cutting tools. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling operations. When working, each knife tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. [0003] Milling cutters are widely used in milling. Existing milling cutters usually consist of a cutter body and a blade fixed on a fixed portion of the cutter body. After a period of use, the blade will become shorter due to wear and cannot continue to be used. Therefore, in the milling process, it is necessary to frequently replace the blades that are shortened due to wear, so that the cost of the tool usage increases sharply. [0004] In addition, the existing milling cutter generally does not hav...
