Abstract

The utility model discloses an elastic cutter, which comprises a blade and a cutter bar, wherein the blade and the cutter bar are elastically connected; the middle of the cutter bar is provided with a through hole; the cutter bar below the through hole is provided with a cut which is 2 millimeters in width; a spring housing is pressed in the through hole; one side face on the left half part of the cutter bar is provided with dovetail groove; the blade is arranged in the dovetail groove; the blade is matched with the dovetail groove; the cutter bar above the blade is provided with a step hole; a round head screw for clamping the blade is arranged in the step hole; and an inclined plane is processed below the round head part at the right end of the round head screw, and can fix the blade on the cutter bar by fastening a nut at the left end of the round head screw. The elastic cutter has the advantages that: the elasticity of the cutter can be improved; and when cutting force is suddenly increased, the front angle of the blade can be reduced, the cutting force is improved during cutting, the machining efficiency and the quality of turned surfaces are improved, and the service life of the cutter is prolonged.

Description

A kind of elasticity cutter
Technical field
The utility model relates to a kind of cutter, the elasticity cutter that uses when relating to processing metal part on a kind of lathe specifically.
Background technology,
At present, when on engine lathe, cutting stainless steel workpiece, particularly when the processing stainless steel screw thread, 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
[purpose of 0003 the utility model is exactly in order to remedy the deficiency of above-mentioned prior art, a kind of elasticity cutter to be provided, and its installs simple; Easy to use; Overall appearance is firm, and when cutter head ran into big cutting resistance, the knife bar that cutter head is installed can carry out elastic shrinkage; Reduced the cutting angle of the depth of cut and cutter, 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 cutter, and it comprises blade and knife bar; Form that elasticity connects between blade and the knife bar of this elasticity cutter; Wherein knife bar is processed by spring steel or tool steel, and the right-hand part of knife bar is a cuboid, and its length is 150 millimeters; Height is 40 millimeters, and wide is 20 millimeters; There is a semicircle boss to upper process at the middle part of knife bar; There is a through hole at the place at semicircle boss; On the knife bar below this through hole, cut out one width and be 2 millimeters the edge of a knife, the Lower Half at knife bar middle part is cut off, 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; The left side overall appearance of knife bar also is a cuboid, and its length is 50 millimeters; Height is 50 millimeters, and wide is 20 millimeters, is processed with a dovetail groove in a side of knife bar left side; The one-sided oblique angle of this dovetail groove is 10 degree, is placed with a blade of being processed by high-speed steel in this dovetail groove, and the cross section of this blade is trapezoidal; Insert shape and dovetail groove are complementary, and the two is slidingly matched, and the knife bar above the blade is provided with a stepped hole; A cheese head screw that is used to tighten blade is housed in the stepped hole; Below the round end of this cheese head screw right-hand member part, processed an inclined-plane, the angle of the axis of this inclined-plane and cheese head screw is 10 to spend, and the said inclined-plane of the nut of fastening cheese head screw left end can be fixed on blade on the knife bar; Knife bar can be alleviated the impact of external force blade in the downwarping of spring housing place nature when blade receives downward active force.
The method for using of the utility model is: be placed on blade in the dovetail groove, expose suitable length, the nut of fastening cheese head screw left end is clamped on blade on the knife bar, and on abrasive machine, grinding out needed cutting edge can come into operation.
The beneficial effect of the utility model is: install simply, easy to use, overall appearance is firm.It can improve the elasticity of cutter head; Anterior angle, side edge relief angle and the top relief angle of lathe tool blade when it can reduce rough turn, half finish turning when cutting force increases suddenly; Cutting force when improving the cutting screw rod; Improved precision, surface quality and production efficiency under the adding of screw rod, reduced processing cost, and cutter life has been improved also.Replacing is installed in the cutter head of the different cutting edges on the cutter holder, can realize the multiple use of a knife bar, has reduced the waste of knife bar, has reduced production cost.
