Abstract
A ring shaped quirk turning cutting tool, including a hilt and at least a tool bit. The turning cutting tool is characterized in that the hilt is a conical grip drill socket, the conical grip is fastened on the rear part of the drill socket. The tool bit is inlayed on the front end surface of the drill socket, the tool bit width is equal to the processing ring-like trench width, the distance between the inside of the tool bit and the drill socket axial cord is equal to the ring-like trench inside radius. The drill socket thickness is smaller than the tool bit width, and a draw back chip space is located in front of the tool bit spot on the drill socket front end surface. An ejecting chip hole can be arranged on the rear end side. The overall rigidity of the utility model is good, the turning is stable and reliable, the cutting tool is avoided from being broken off, the turning efficiency is 3 times of the efficiency of a rimmer knife ring-like trench turning cutting tool, the defect that the bad rigidity of the existing rimmer knife ring-like trench turning cutting tool easily causes vibration is overcome.
Description
Technical field
The utility model relates to a kind of annular deep trouth turning cutting tool.
Background technology
When the processing work section is annular deep trouth, as process the annular deep trouth of the dark 72mm of wide 10mm, because the workpiece end face groove is narrow and dark, the lathe tool cutter head is narrower, the lathe tool knife bar is longer, and poor rigidity causes swaging clamp easily and chatters phenomenon, the iron filings of workpiece amount are the clockwork spring shape and curl during cutting, the chip removal difficulty, the cutting temperature height, the lathe tool cutter weares and teares easily, cutting force increases, and stock-removing efficiency is low.The lathe tool cutter head is equivalent to the car endoporus during smear metal, and the cutter head relief angle is pressed end face arc size sharpening, avoids pair back and groove circular arc to collide, and has weakened the intensity of lathe tool more.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing annular deep trouth turning cutting tool, the utility model provides a kind of stock-removing efficiency high annular deep trouth turning cutting tool.
Design of the present utility model is fastening conical grip at the rear portion of drill bushing, is inlaying cutter head at the front end of drill bushing, and there is bit-withdrawing slot the front of cutter head, the side, rear end of drill bushing chip-removal hole is being set.
The utility model comprises a handle of a knife and a minimum cutter head, 1 to 4 cutter head is generally arranged, it is characterized in that: said handle of a knife is the drill bushing that has conical grip, conical grip is fastened on the rear portion of drill bushing, the tapering of conical grip is generally Mohs No. 5, cutter head is embedded in the end face before the drill bushing, the width of cutter head equates with the width of the annular deep trouth of processing, the inboard of cutter head equals the radius of annular deep trouth inboard to the distance of drill bushing axis, the thickness of drill bushing is less than the width of cutter head, the inboard of one ship cutter head and the outside are than the big 1.5mm of drill bushing, and there is bit-withdrawing slot at the position before the front end end face of drill bushing is positioned at cutter head, are beneficial to and move back bits.
Above-mentioned annular deep trouth turning cutting tool is characterized in that: the cutter head of inlaying two relative drill bushing axis symmetries at drill bushing.
For the ease of turning, the major cutting edge ecto-entad of cutter head and drill bushing end slope, the angle of inclination is 1.5 °-2 °.For the ease of going out bits, chip-removal hole is being set in the side, rear end of drill bushing.
The utility model is taked said structure, cutter head is embedded in the drill bushing that has conical grip, increased the cutter whole rigidity, reliable and stable during turning, avoid the cutter that fractures, turning efficient is 3 times of rimmer knife burr shape deep trouth turning cutting tool, has overcome the deficiency that existing rimmer knife burr shape deep trouth turning cutting tool rigidity difference is easy to generate vibration.Save alloy blade and high-speed steel bit, reduced the roughness value of machined surface.If inlaying the cutter head of two relative drill bushing axis symmetries at drill bushing, turning is more stable.
