Abstract
An elastic inner hole turning tool includes a tool head and a tool rod, wherein a handle part on the right side of the tool rod is a cuboid; the cross section of the tool arm part on the left side of the tool rod is an oval cylinder; a square hole mounted with the tool head is formed on the left side of the tool rod; a screw hole is formed above the square hole; a propping screw screwed in the screw hole tightly props against the tool head in the square hole; a through hole is formed on the right side of the square hole; a cut opening with 2 mm width is cut out on the tool rod below the through hole, so as to cut off the tool rod below the through hole; a spring sleeve is pressed into the through hole; a cut opening with 1 mm width is cut out in the axis direction at the upper part of the spring sleeve. When the tool head is under the downward cutting force, the tool rod naturally bends downward at the spring sleeve, so as to buffer the impact of the external force toward the tool head. The utility model has the benefits that the elasticity of the tool is improved, the cutting capability is improved, the machining precision and the production efficiency are improved, the machining cost is reduced, and the service life of the tool is prolonged.
Description
Technical field
The utility model relates to a kind of cutter, the elasticity internal lathe-tool that uses when relating to processing metal part endoporus on a kind of lathe specifically.
Background technology,
At present, during the endoporus of the workpiece that on engine lathe, cuts stainless steel, particularly when the internal thread of processing stainless steel part, because the variation of cutting force is bigger in whole working angles, through be damaged cutter or damage the situation of part to be processed of regular meeting.Analyze reason and mainly be since existing welding hard alloy steel cutter head rigid blade arbor in the process of Vehicle Processing, the anterior angle of himself, side edge relief angle and top relief angle immobilize, cutter itself can not change along with the change of cutting data.Since the defective of cutter self, make that the cutter loss is serious, the time of increased tool changing repeatedly, whetting a knife repeatedly, reduced operating efficiency, reduced product percent of pass, improved production cost.
The utility model content
The purpose of the utility model is exactly in order to remedy the deficiency of above-mentioned prior art; A kind of elasticity internal lathe-tool is provided, and it installs simple, and is easy to use; When cutter head runs into big cutting resistance; The knife bar that cutter head is installed can carry out strain, has reduced the cutting angle of the depth of cut and cutter, and the protection cutter head is injury-free.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of elasticity internal lathe-tool, and it comprises cutter head and knife bar; Form that elasticity connects between cutter head and the knife bar of this elasticity internal lathe-tool; Wherein knife bar is processed by medium carbon steel, and the shank portion on knife bar right side is a cuboid, and knife bar left side tool arm partly is that cross section is oval-shaped cylinder; And long axis of ellipse is a vertical direction; The vertical center and be provided with a square hole that cutter head is installed in knife bar left side apart from 10 millimeters places, knife bar left side, there is a screw square hole top, is connected with one in this screw and holds out against screw cutter head is held out against in square hole; Minor axis at 50 millimeters places, said square hole right side along oval knife bar is provided with a through hole; The otch that on the knife bar below this through hole, cuts out one width and be 2 millimeters cuts off knife bar below through hole; In above-mentioned through hole, be pressed into a spring housing; This spring housing is to be processed through heat treatment again after machining by spring steel, and it is 1 millimeter otch that there is a width on the top of this spring housing along axis direction; Knife bar can be in the downwarping of spring housing place nature when cutter head receives downward active force, thereby alleviates the impact of external force to cutter head.
The beneficial effect of the utility model is: it can improve the elasticity of cutter head; Anterior angle, side edge relief angle and the top relief angle of lathe tool cutter head when it can reduce rough turn, half finish turning when cutting force increases suddenly; Cutting force when improving cutting; Improved machining accuracy, surface quality and production efficiency, reduced processing cost, and cutter life also is improved.

The specific embodiment
Among the figure, a kind of elasticity internal lathe-tool, it comprises knife bar 1 and cutter head 2; Wherein knife bar 1 is processed by medium carbon steel, and the shank portion on knife bar 1 right side is a cuboid, and knife bar 1 left side tool arm partly is that cross section is oval-shaped cylinder; And long axis of ellipse is a vertical direction; Be provided with a square hole that cutter head 2 is installed at vertical center, knife bar 1 left side and apart from 10 millimeters places, knife bar 1 left side, square hole top is shaped on a screw, is connected with one in this screw and holds out against screw 3 cutter head 2 is held out against in square hole; Minor axis at 50 millimeters places, said square hole right side along oval knife bar 1 is shaped on a through hole; The otch that on the knife bar below this through hole 1, cuts out one width and be 2 millimeters cuts off 1 part of the knife bar below the through hole; In above-mentioned through hole, be pressed into a spring housing 4; This spring housing 4 is to be processed through heat treatment again after machining by spring steel, and it is 1 millimeter otch that the top of this spring housing 4 is shaped on a width along axis direction.
Claims (4)
1. elasticity internal lathe-tool; It is characterized in that: it comprises cutter head and knife bar, and the shank portion on knife bar right side is a cuboid, and knife bar left side tool arm partly is that cross section is oval-shaped cylinder; And long axis of ellipse is a vertical direction; Be provided with a square hole that cutter head is installed at vertical center, knife bar left side and apart from 10 millimeters places, knife bar left side, there is a screw square hole top, is connected with a screw in this screw cutter head is held out against in square hole; Minor axis at 50 millimeters places, said square hole right side along oval knife bar is provided with a through hole, and the otch that on the knife bar below this through hole, cuts out one width and be 2 millimeters cuts off knife bar below through hole, in above-mentioned through hole, be pressed into a spring housing.
