Abstract
The utility model discloses a vibration resistant cutter bar of a boring cutter, relates to the field of machining cutters, and provides a cutter bar of the boring cutter used for boring of deep holes. The vibration resistant cutter bar comprises a cutter bar body, wherein a vibration resistant part is arranged at the middle part of the length direction of the cutter bar body and in the length direction of cutter bar body and made of a cemented carbide material or heavy metal. When a deep hole is processed by using the vibration resistant cutter bar of the boring cutter disclosed by the utility model, the vibration of the cutter bar of the boring cutter is remarkably reduced, and the hole, the depth of which is 6 to 10 times of the diameter of the cutter bar, can be processed.

Deep hole boring is the difficult point of boring processing always, and the key of solution deep hole boring is manufacturing and designing of deep-hole boring cutter.Existing deep hole boring boring cutter adopts the manufacturing of steel global formation, and the boring depth general control is in 4 times of diameters of knife bar, and 4～6 times of diameters need to reduce cutting parameter, and surpassing 6 times of diameter steel integrated boring bars can't process.
The utility model content
The technical problems to be solved in the utility model is: a kind of boring bar that is conducive to deep hole boring is provided.
For the technical scheme that addresses the above problem employing is: the antivibration boring bar comprises the knife bar body, and the middle part of knife bar body length direction is provided with antivibration section along knife bar body length direction.
Concrete is: the knife bar body comprises boring cutter connecting portion and lathe connecting portion, boring cutter connecting portion one end is provided with connecting hole, lathe connecting portion one end is provided with connecting hole, and antivibration minister degree direction two ends are provided with boss, and two boss are connected by interference fit with two connecting holes respectively.
Be further: the lathe connecting portion is tapered knife shank type structure.
Concrete is: knife bar body inside is provided with cavity, and antivibration section is filled in cavity.
Be further: knife bar body one end is tapered knife shank type structure.
Concrete is: the knife bar body comprises the boring cutter connecting portion, and boring cutter connecting portion one end is provided with connecting hole, and antivibration minister degree direction one end is provided with boss, and boss is connected by interference fit with connecting hole.
Concrete is: an end of described knife bar body length direction is lathe link end face, is provided with blind hole along knife bar body length direction in the knife bar body, and the aperture of blind hole is positioned on lathe link end face, and antivibration section is filled in blind hole.
The beneficial effects of the utility model are: to be difficult to process the reason in very dark hole be that to add knife bar vibration in man-hour excessive to the steel integrated knife bar according to the study.The middle part of knife bar body length direction is provided with antivibration section along knife bar body length direction, antivibration section material is carbide alloy or heavy metal, hard closes or heavy metal has elastic modelling quantity and the higher characteristics of density, the vibration of knife bar when being conducive to reduce boring, according to experiment, use boring bar deep hole processing of the present utility model, the vibration of boring bar obviously reduces, and can working depth be the hole of 6 to 10 times of knife bar diameters.
