Detailed description of the invention
Fig. 1 is the scraper of removal thread bottom burr of the invention.
Fig. 2 is the scraper of burr at the top of removal thread of the invention.
Specific embodiment
The present invention will be described with reference to the accompanying drawings and examples.
It is a kind of for removing the Special scraper knife of high-accuracy screw thread between cog burr, including for removing thread bottom burr Scraper, the scraper for removing burr at the top of thread;Scraper for removing thread bottom burr includes 1 He of the first cutter head First knife handle 2, the first cutter head 1 be it is rod-shaped, head-bent is in wedge angle, and bottom and the first knife handle 2 are cooperatively connected;For removing screw thread The scraper of tooth crest burr includes the second cutter head 3 and the second knife handle 4, and the second cutter head 3 is rod-shaped, head-bent, inside at head By form of thread angle grooving, bottom and the second knife handle 4 are cooperatively connected.
Connection between first cutter head 1 and the first knife handle 2 uses Cone fit, guarantees that concentricity is higher, and in matching hole Mouth is fixed using gluing.
First cutter head 1, the second cutter head 3 material be chosen for high rigidity, higher wearability, and there is certain toughness High-speed steel, formed with linear cutter.
Second knife handle 2, the second knife handle 4 material choose have good corrosion resistance and higher hardness, be easy The stainless steel material of processing.
Wherein the characteristics of the scraper of thread bottom, as shown in Figure 1, the head of the first cutter head 1 uses radiused transition, nose angle α, double-sided blade grinding, ensure that the sharp of point of a knife, scraper stress is smaller.It is smaller to design anterior angle, guarantees that scraper has some strength. Angle beta, tool cutting edge angle γ and auxiliary angle δ are larger afterwards, ensure that the sharp of blade.It is mainly used for remaining after removing vehicle, milling, pincers processing The burr at remaining thread bottom.The value range of the nose angle α on head is 40 °~50 °, the value of tool cutting edge angle γ and auxiliary angle δ Range is 65 °~70 °.The value range of the rear angle beta on head is 63 °~67 °.
Wherein the characteristics of screw thread tooth top scraper, as shown in Fig. 2, the head of the second cutter head 3 uses radiused transition, at point of a knife Inwardly press form of thread angle ε grooving, design anterior angle ζ be it is smaller, guarantee scraper have some strength.Relief angle η is larger, and slot two sides are double Face sharpening is cut, and ensure that the sharp of blade.It remains in the burr on screw thread tooth top after being mainly used for vehicle, milling, pincers processing.Anterior angle The value of ζ is 55 ° or 60 °, and the value range of relief angle η is 18 °~22 °.
Embodiment:
