Abstract
The utility model belongs to technical field of mechanical processing, is related to a kind of antidetonation boring cutter bar.It includes boring bar, the cutter head for being set to boring bar end, it is characterized by: the boring bar is provided with damping axocoel in the shaft of cutter head, the elastic axis is intracavitary to be provided with lead and damping spring, and the both ends of the lead pass through damping spring respectively and connect with the both ends of damping axocoel；Lead and damping spring is arranged in the utility model in boring bar, is moved back and forth between damping spring by lead, offsets the shaking force on boring bar, solves longer boring bar vibration, the problem for causing the hole size of processing, precision low.
Description
Technical field
The utility model belongs to technical field of mechanical processing, is related to a kind of antidetonation boring cutter bar.
Background technique
Boring cutter is one kind of aperture knife tool, and the processing of deep hole of workpiece is generally added using fixed cylindrical type boring cutter bar
Work, since this boring cutter bar is cantilever design, will quiver knife when draw ratio is greater than 6:1, and the inner hole of processing is not up to
To size requirement.
Utility model content
The purpose of this utility model is in view of the problems of the existing technology to provide a kind of antidetonation boring cutter bar.
The specific technical solution of the utility model is as follows:
A kind of antidetonation boring cutter bar including boring bar, is set to the cutter head of boring bar end, it is characterised in that: the boring bar is close
Damping axocoel is provided in the shaft of cutter head, the elastic axis is intracavitary to be provided with lead and damping spring, the both ends of the lead
It is connect respectively by damping spring with the both ends of damping axocoel；
Further, the boring bar includes basic boring bar and damping boring bar, and the damping boring bar passes through connecting shaft and basis
Boring bar connection, the cutter head are installed on damping boring bar end, and the damping axocoel is located in damping boring bar；
It further, further include adjusting bolt and pressing plate, it is intracavitary that the pressing plate is located at elastic axis, adjusts bolt across damping
One end of axocoel inserts into the inner and connect with pressing plate, and the pressing plate is connect with the damping spring of lead one end.
The utility model has the following beneficial effects:
Lead and damping spring is arranged in the utility model in boring bar, is moved back and forth between damping spring by lead,
The shaking force on boring bar is offset, solves longer boring bar vibration, the problem for causing the hole size of processing, precision low.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
A kind of antidetonation boring cutter bar as shown in Figure 1 including boring bar 1, is set to the cutter head 2 of 1 end of boring bar, the boring bar 1
It is provided with damping axocoel 3 in the shaft of cutter head 2, lead 4 and damping spring 5, the lead are provided in the damping axocoel 3
The both ends of block 4 pass through damping spring 5 respectively and connect with the both ends of damping axocoel 3.
The antidetonation boring cutter bar of the utility model may be fabricated structure, specifically, the boring bar 1 includes basic boring bar
1-1 and damping boring bar 1-2, the damping boring bar 1-2 are connect by connecting shaft 1-3 with basis boring bar 1-1, and the cutter head 2 is installed
In the end damping boring bar 1-2, the damping axocoel 3 is located in damping boring bar 1-2；The antidetonation boring cutter bar further includes adjusting bolt
6 and pressing plate 7, the pressing plate 7 be located in damping axocoel 3, adjust bolt 6 pass through damping axocoel 3 one end insert into the inner and with pressure
Plate 7 connects, and the pressing plate 7 is connect with the damping spring 5 of 4 one end of lead.
The antidetonation boring cutter bar shock absorption principle of the utility model are as follows:
When boring cutter carries out bore hole operation to workpiece, vibration is generated on boring bar 1, shaking force is transferred to lead 4 by damping spring 5
On, for lead 4 between its both ends damping spring 5, the axial direction along damping axocoel 3 moves back and forth meeting, lead 4 and damping spring
The vibration on boring bar 1 is offset under 5 collective effects, guarantees the precision of work pieces process inner hole.
The utility model can choose the basic boring bar 1-1 of corresponding length according to boring depth, install damping boring bar additional on it
1-2 makes it have shock-absorbing function, specific assembly and adjustment process are as follows: damping boring bar 1-2 is passed through connecting shaft 1-3 and basic boring bar
1-1 is fixedly connected, the basic boring bar 1-1 of different length, and the shaking force that bore hole process generates is different, and rotation adjusts bolt 6, is pushed away
7 compression shock absorption spring 5 of dynamic pressure plate, the different compression degree of damping spring 5 can offset the shake on the boring bar 1-1 of different length basis
Power, so that damping boring bar 1-2 can be applicable in the damping work of various sizes of basic boring bar 1-1.
