Abstract
The utility model provides a T-shaped milling cutter structure for key slots in order to solve the problems of severe material waste, large needed machining amount and the like due to the fact that a T-shaped milling cutter for key slots in the prior art is of an integral structure. The T-shaped milling cutter structure for the key slots comprises a milling cutter handle, a milling cutter blade portion, a washer and a fixing nut, the milling cutter handle is cylindrical, a lower section of the milling cutter handle is provided with a fixing step, a fixing section and a thread section in sequence, the outer diameter of the fixing step is larger than the inner diameter of a central through hole of the milling cutter blade portion, and the outer diameter and the length of the fixing section are matched with the inner diameter of the central through hole of the milling butter blade portion and the thickness of the milling butter blade portion. The milling butter blade portion is circular, a through hole is formed in the center of the milling butter blade portion, and milling cutter blades are arranged at the outer edge of the milling butter blade portion. An inner thread of the fixing nut is matched with a thread of the thread section at the lower end of the milling cutter handle. The T-shaped milling cutter structure for the key slots has the advantages that after the T-shaped blade portion for the key slots is blunt or damaged, only the blade portion of the T-shaped milling cutter needs to the replaced, so that raw materials are saved, and machining amount is decreased obviously.
Description
Technical field
The utility model relates to a kind of keyway process technology, specially refers to a kind of keyway T shape milling cutter construction.
Background technology
In the plant equipment manufacture process, need process keyway in the bar portion of shaft element usually, and use in the assembling process afterwards.Usually, adopt and mill processing mode processing keyway, mainly comprise slotting cutter and T shape milling cutter.Slotting cutter is from the vertical direction processing keyway of part bar portion, and T shape milling cutter is from the horizontal direction processing keyway of part bar portion.Prior art keyway T shape milling cutter adopts overall structure, and namely the shank of T shape milling cutter and blade are an integral body, when blade blunt or damage after, then whole milling cutter scrapped.In addition, integrally-built T shape milling cutter need to adopt diameter to process greater than the material of blade external diameter when production and processing, processes after perhaps adopting diameter to forge jumping-up greater than the material of shank.Adopt first method to process, because the shank axial dimension of T shape milling cutter will cause serious waste of material much larger than the blade axial dimension, and, need bigger processing capacity.Adopt second method to process, because Forge Heating oxidation and forging back shape are lack of standardization, can cause waste of material equally and need bigger processing capacity.Obviously, prior art keyway T shape milling cutter adopts overall structure to exist waste of material seriously and needs bigger problems such as processing capacity.
Summary of the invention
Serious and need bigger problems such as processing capacity for overcoming waste of material that prior art keyway T shape milling cutter adopts overall structure to exist, the utility model proposes a kind of keyway T shape milling cutter construction.The utility model keyway T shape milling cutter construction comprises milling cutter shank, milling cutter blade, packing ring and hold-doun nut; The milling cutter shank is cylindric, its hypomere is disposed with fixedly step, canned paragraph and thread segment, fixedly the external diameter of step is greater than the internal diameter of milling cutter blade central through hole, and the internal diameter of the external diameter of canned paragraph and length and milling cutter blade central through hole and the thickness of milling cutter blade are complementary; The milling cutter blade is circular, and its center is provided with through hole, and outer rim is the milling cutter sword; The internal thread of hold-doun nut and milling cutter shank subordinate hold the screw thread of thread segment to be complementary.
Further, the fixedly step of the utility model keyway T shape milling cutter construction is provided with the anti-rotation boss, is provided with the anti-rotation groove at milling cutter blade correspondence position, and the size of the size of its anti-rotation boss and anti-rotation groove is complementary.
The useful technique effect of the utility model keyway T shape milling cutter construction be the blade when keyway T shape blunt or damage after, only need to change the blade of T shape milling cutter.And, when the blade of processing T shape milling cutter, can use external diameter to be slightly larger than the material of blade external diameter and only to need and process on a small quantity, not only saved raw material, also significantly reduced processing capacity.
Description of drawings
Accompanying drawing 1 is the schematic three dimensional views of the utility model keyway T shape milling cutter construction.
Below in conjunction with drawings and the specific embodiments the utility model keyway T shape milling cutter construction is described further.
The specific embodiment
Accompanying drawing 1 is the schematic three dimensional views of the utility model keyway T shape milling cutter construction, and among the figure, 1 is the milling cutter shank, and 2 is the milling cutter blade, 3 is packing ring, and 4 is hold-doun nut, and 1-1 is fixing step, and 1-2 is canned paragraph, 1-3 is thread segment, and 1-4 is the anti-rotation boss, and 2-1 is the anti-rotation groove.As seen from the figure, the utility model keyway T shape milling cutter construction comprises milling cutter shank 1, milling cutter blade 2, packing ring 3 and hold-doun nut 4; The milling cutter shank is cylindric, its hypomere is disposed with fixedly step 1-1, canned paragraph 1-2 and thread segment 1-3, fixedly the external diameter of step 1-1 is greater than the internal diameter of milling cutter blade central through hole, and the internal diameter of the external diameter of canned paragraph 1-2 and length and milling cutter blade central through hole and the thickness of milling cutter blade are complementary; Milling cutter blade 2 is circular, and its center is provided with through hole, and outer rim is the milling cutter sword; The internal thread of hold-doun nut 4 and milling cutter shank subordinate hold the screw thread of thread segment to be complementary.When assembling, milling cutter blade, packing ring and hold-doun nut are sleeved on milling cutter shank subordinate section successively, because the external diameter of the canned paragraph of milling cutter shank and the internal diameter of length and milling cutter blade central through hole and the thickness of milling cutter blade are complementary, by hold-doun nut can make the milling cutter blade firm be fixed on the milling cutter shank.When the blade of keyway T shape blunt or damage after, only need to change the blade of T shape milling cutter, be about to hold-doun nut and unclamp, it is blunt or damage the milling cutter blade to take off, and changes new milling cutter blade and can use.Because the milling cutter blade of the utility model keyway T shape milling cutter construction is circular, the material that adopts external diameter to be slightly larger than the blade external diameter can be processed.And only need a small amount of processing, not only saved raw material, also significantly reduced processing capacity.
Cause that the milling cutter shank rotates at milling cutter shank canned paragraph for preventing because hold-doun nut is loosening, the fixedly step of the utility model keyway T shape milling cutter construction is provided with anti-rotation boss 1-4, be provided with anti-rotation groove 2-1 at milling cutter blade correspondence position, the size of the size of its anti-rotation boss and anti-rotation groove is complementary.Like this, even hold-doun nut is loosening to some extent, the milling cutter shank can not rotate at milling cutter shank canned paragraph yet.
Obviously, the useful technique effect of the utility model keyway T shape milling cutter construction be the blade when keyway T shape blunt or damage after, only need to change the blade of T shape milling cutter.And, when the blade of processing T shape milling cutter, can use external diameter to be slightly larger than the material of blade external diameter and only to need and process on a small quantity, not only saved raw material, also significantly reduced processing capacity.
