Description

Technical Field

[0001] The utility model belongs to the technical field of cutting tools and relates to a gear turning tool, in particular to a special cylindrical gear turning tool. Background Art

[0002] A gear turning cutter is a cutting tool with spur or involute teeth. It is designed to efficiently and accurately process spur gears, bevel gears, threaded and progressive parts. When processing cylindrical gears of specific shapes or sizes, special cylindrical gear turning cutters are used for processing.

[0003] During the machining process, the gear turning cutter cuts the material into the desired tooth shape through the interaction between the high-speed rotating teeth and the processed material. The contact between the teeth and the processed material will generate a large friction force, which will aggravate the wear of the gear turning cutter teeth and shorten the service life of the gear turning cutter. Therefore, it is of great significance to design a special cylindrical gear turning cutter. Summary of the invention

[0004] The utility model aims to provide a special cylindrical gear cutting tool in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a special cylindrical gear cutting tool, characterized in that it includes a cutter body, an oil chamber is opened on the inner wall of the cutter body, a plurality of oil guide grooves connected with the oil chamber are opened on the inner wall of the cutter body, a rotatable sealing plate is arranged in the oil chamber, a plurality of oil blocking plates are fixedly arranged on the surface of the sealing plate, a limiting groove is opened on one side of the cutter body, a toggle rod is fixedly arranged on one side of the oil blocking plate, and the toggle rod is located in the limiting groove.

[0006] In the above-mentioned special cylindrical gear cutting tool, a rotatable connecting plate is provided on the surface of one end of the toggle rod, and the connecting plate is located on one side of the cutter body, a bolt is provided on the connecting plate, and a positioning hole for use with the bolt is opened on one side of the cutter body, and the number of the positioning holes is two.

[0007] In the above-mentioned special cylindrical gear cutting tool, an oil filling hole is opened on one side of the cutter body, and a second bolt is arranged on the oil filling hole.

[0008] Compared with the prior art, the Bent-shaped cylindrical gear cutting tool injects lubricating oil so that the lubricating oil flows to the surface of the cutter teeth when cutting is required, thereby lubricating the cutter teeth, reducing frictional wear on the cutter teeth and extending the service life of the cutter body.
