Abstract
The utility model discloses an improved structure of a grooving cutter, which comprises a cutter bar, a cutter head bar and a cutter blade; the inner end of the cutter head rod is fixed on the cutter bar, and the cutter blade is fixed outside the cutter head rod; the blade is fixed at the front end of the cutter head rod, and the blade is a symmetrical cylinder. Because the blade is a symmetrical cylinder and is provided with a plurality of blades, one blade can be continuously used after being regulated after being worn during processing, and the service life of the cutter is long and the cost is low; in addition, the cutter head rod has thicker thickness, good rigidity and longer length, and can be used for processing grooves with wider width and deeper depth.
Description
Technical Field
The utility model relates to a cutter, in particular to an improved structure of a grooving cutter.
Background
The tool is a tool for cutting machining in machine manufacturing, and is mainly used for cutting metal materials. As shown in fig. 1, the conventional cutting tool includes a tool holder 1', a tool bit 2', and a blade 3', wherein the blade 3' is long, and when the cutting tool is processed, only an outer edge of the blade 3 'can cut, and the service life of the blade 3' is short.
Disclosure of Invention
The utility model aims to provide an improved structure of a grooving cutter.
In order to achieve the above object, the technical solution of the present utility model is:
the utility model relates to an improved structure of a grooving cutter, which comprises a cutter bar, a cutter head bar and a cutter blade; the inner end of the cutter head rod is fixed on the cutter bar, and the cutter blade is fixed outside the cutter head rod; the blade is fixed at the front end of the cutter head rod, and the blade is a symmetrical cylinder.
The front end of the cutter head rod is provided with a triangular groove with one open end, the bottom of the triangular groove is provided with a yielding groove, the cutter blade is fixed in the triangular groove, and the cutter blade is a cylinder with a triangular cross section.
The front end of the cutter head rod is provided with a circular groove with one open end, the cutter blade is fixed in the circular groove, and the cutter blade is a cylinder with a circular cross section.
The section of the tool bit rod is arc-shaped.
After the scheme is adopted, the cutter comprises the cutter bar, the cutter head rod and the cutter blade, wherein the cutter blade is fixed at the front end of the cutter head rod and is a symmetrical cylinder and provided with a plurality of cutter blades, one cutter blade is worn during processing, the other cutter blades can be continuously used after being adjusted, and the cutter has long service life and lower cost; in addition, the cutter head rod has thicker thickness, good rigidity and longer length, and can be used for processing grooves with wider width and deeper depth.
The utility model will be further described with reference to the drawings and the specific examples.
