Abstract
The utility model belongs to the technical field of machining, relates to a key slot milling cutter applicable to milling and processing of shaft parts, and particularly relates to a fine-tooth high-helix key slot finish-milling cutter. The key slot finish-milling cutter comprises a cutter bar, wherein a tool bit is arranged at the end part of the cutter bar; cutting blades are arranged on the tool bit; six cutting blades are arranged, and evenly arranged at the outer circumferential surface of the tool bit in a spiral shape; a chip pocket is formed between two cutting blades; the included angle alpha between any cutting blade and the axis of the cutter bar is 50+/-0.5 degrees. By adopting the fine-tooth high-helix key slot finish-milling cutter, six evenly distributed spiral cutting blades are arranged on the tool bit; the quantity of the blades is large; the milling effect is good; meanwhile, the chip pocket between two adjacent cutting blades is in an arc shape, so that the cutter is good in overall rigidity and high in strength, and has high processing quality and production efficiency when large-width key slots are milled on the shaft parts.
Description
Technical field
The utility model belongs to the machining technique field, relates to a kind of cotter mill cutter that is applicable to axial workpiece milling processing, specifically a kind of serration king bolt keyway milling cutter.
Background technology
The cotter mill cutter of milling key groove on axial workpiece commonly used is GB taper key way milling cutter (GB113-81) at present, popular name lips slotting cutter, comprise: the handle of a knife of integrative-structure and cutter head, evenly be provided with two helical form blades on the cutter head, form chip pocket between the adjacent helical form blade, the pitch angle alpha will of helical form blade is 20 ° ± 0.5 °.
Above-mentioned cotter mill cutter exist shortcoming be: blade is few, chip pocket is large, cutter poor rigidity, intensity are low; On axial workpiece during the large width keyway of milling, rigidity and insufficient strength, cutting vibration is very large, easily causes the distortion of blade trace, causes cutting edge to tilt.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of serration king bolt keyway milling cutter simple in structure, ingenious, rational is provided, and this opener organically combines opening and dental care benefits, not only can improve surgical field of view; and can protect the patient, the inorganization damage.
The technical scheme that provides according to the utility model: a kind of serration king bolt keyway milling cutter, comprise knife bar, described knife bar end is cutter head, offer cutting blade at described cutter head, be characterised in that: described cutting blade has six, and six cutting blade is evenly arranged on the outer circumference surface of cutter head in the shape of a spiral, has chip pocket between adjacent two cutting blades, and the angle α between any described cutting blade and knife bar axis is 50 ° ± 0.5 °.
As further improvement of the utility model, described chip pocket is the circular arc chip pocket.
The utility model compared with prior art, advantage is: have six uniform helical form cutting blades on the utility model cutter head, blade is more, and milling effect is good; Simultaneously the chip pocket between the adjacent cutting blade is circular arc, so that the cutter integral rigidity is good, intensity is high, during the large width keyway of milling, has higher crudy and production efficiency on axial workpiece.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, comprise cutter head 1, cutting blade 11, chip pocket 12, knife bar 2 etc.
As shown in Figure 1 and Figure 2, the utility model is a kind of serration king bolt keyway milling cutter, comprise knife bar 2, described knife bar 2 ends are cutter head 1, offer cutting blade 11 at described cutter head 1, described cutting blade 11 has six, and six cutting blades 11 are evenly arranged on the outer circumference surface of cutter head 1 in the shape of a spiral, have chip pocket 12 between adjacent two cutting blades 11, the angle α between any described cutting blade 11 and knife bar 2 axis is 50 ° ± 0.5 °
Described chip pocket 12 is the circular arc chip pocket.
Have six uniform helical form cutting blades on the utility model cutter head, blade is more, and milling effect is good; Simultaneously the chip pocket between the adjacent cutting blade is circular arc, so that the cutter integral rigidity is good, intensity is high, during the large width keyway of milling, has higher crudy and production efficiency on axial workpiece.
