Background technology
In the lathe grinding course of processing, because commonly its structure of amputation knife is monolithic construction and is provided without any damping
Measure, just because of itself this structure of common amputation knife, so being easier in process to produce vibration, vibrates meeting
Destroy and disturb normal machining, deteriorate workpiece surface quality, produce obvious surface chatter mark, the roughness of workpiece
Thus increase, the method that at this moment operator would generally take reduction cutting data cause working (machining) efficiency to substantially reduce again.
Utility model content
In order to solve the vibration problem in cutting process, this utility model provides a kind of vibration damping amputation knife, and this is cut
Breaking is designed with Silencing groove in cutter front end, can significantly improve the machining accuracy of workpiece, produces in effectively mitigating the course of processing
Vibration, improve working (machining) efficiency.
This utility model solves the technical scheme of technical problem employing：A kind of vibration damping amputation knife are provided, including blade
Concrete with knife, the specific front portion of knife is provided with insert groove, and blade is arranged in insert groove by trip bolt；It is characterized in that in knife
The lower section of piece, and Silencing groove is particularly provided with knife, the Silencing groove is made up of rectangular slot and transition circle groove, rectangle
Groove lower end is concordant with the concrete bottom of knife, the upper end connection transition circle groove of rectangular slot, the diameter of the transition circle groove
For 1.05-1.5 times of rectangular slot groove width, the distance of the concrete front end of centre-to-centre spacing knife of rectangular slot is rectangular slot groove
Wide 3-3.5 times.
Compared with prior art, the beneficial effects of the utility model are：
When during cut-out or grooving, cutter is affected maximum to be tangential force, amputation knife are affected by so as to produce
Raw vibration, this utility model by arranging the Silencing groove being made up of rectangular slot and transition circle groove in the concrete front end of knife,
And transition circle groove is located at the top of rectangular slot, effectively prevent stress concentration, such amputation knife in process may be used
To make the purpose that tangential force decays so as to reach vibration damping by the elastic deformation of Silencing groove.This utility model amputation knife can be used for
The groove of process component is used for cutting off parts, in processing groove or cut-out parts, during parts machining
Vibration is larger, and the end face surface roughness that can cause the groove or parts for processing is too poor, the end face precision of groove or parts
Not high the problems such as, this utility model amputation knife, can improve the end face surface roughness and essence of the groove or parts for processing
Degree, meets industrial requirement.
Test shows that amplitude of the common amputation knife in machining is about 0.1mm, and this utility model amputation knife are being cut
The amplitude cut in processing is about 0.09mm, and this utility model amputation knife are lower than the amplitude of common amputation knife work in-process 10% left
The right side, the service life of cutter blades can increase by 15% or so.

Specific embodiment
This utility model vibration damping amputation knife (referring to Fig. 1-3) includes blade 3 and knife concrete 1, and the front portion of knife concrete 1 is provided with knife
Film trap, blade 3 are arranged in insert groove by trip bolt 2；In the lower section of blade 3, and Silencing groove 4 is provided with knife concrete 1,
The Silencing groove 4 is made up of (referring to Fig. 3) rectangular slot 4.1 and transition circle groove 4.2, and rectangular slot lower end is concrete with knife
Bottom is concordant, the upper end connection transition circle groove of rectangular slot, a diameter of rectangular slot groove width of the transition circle groove
1.05-1.5 times, 3-3.5 times for rectangular slot groove width of the distance of the concrete front end of centre-to-centre spacing knife of rectangular slot.
The width for being further characterized by the blade of the present utility model is 2-6mm.
The depth for being further characterized by the rectangular slot of the present utility model is 1.8-2.5mm.
In this utility model, rectangular slot refers to and is rectangle that its groove width is referred in the front view (Fig. 1) of amputation knife
In front view along cutter body length direction rectangular slot size, its depth referred in front view along specifically long perpendicular to knife
The size of rectangular slot on degree direction；Transition circle groove is rounded in front view.
The installation of this utility model vibration damping amputation knife and occupation mode are：
(1) blade 3 is inserted in the insert groove of knife concrete 1, is then locked by trip bolt 2；
(2) and then by the amputation knife it is installed on lathe saddle, pretension is carried out to cutter with the trip bolt of lathe saddle,
Then to knife, point of a knife is made with the same height of the geometric center of workpiece to be machined and blade will just to being cut part, if difference Gao Ze
The trip bolt of lathe saddle is unclamped, amputation knife is highly adjusted, is carried out to knife again after adjustment, until point of a knife and quilt
The geometric center of processing workpiece is with high；
