Description
Technical field
The utility model belongs to technical field of mechanical processing, is related to a kind of counterbore processing boring and milling cutter.
Background technology
The existing typically first finish-milling bottom surface of shell counterbore finishing is to depth dimensions, and side wall stays right boring surplus, then right boring is extremely
Size, this mode need tool change time twice, processing efficiency low；Two knife machining accuracies, it is difficult to ensure that the required accuracy, even
Lead to the component after assembling, hydraulic test volumetric efficiency cannot be up to standard.Production cost and quality is not only affected in this way, it is more uncomfortable
Close product batch production.
Utility model content
The utility model aim is overcome the deficiencies in the prior art, adapts to the needs of reality, provides a kind of counterbore processing
Boring and milling cutter.
The utility model is realized in this way：
A kind of counterbore processing boring and milling cutter, it includes boring and milling knife bar, blade and blade screw, and the head sizes of boring and milling knife bar are big
In the shaft size of boring and milling knife bar, blade is equilateral triangle structure, and blade is mounted on boring and milling knife rod head by blade screw
In knife holder slot, the wherein a line of blade stretches out in boring and milling cutter bar and forms blade, and the both ends of blade are point of a knife, blade and boring and milling cutter
The axis of bar is vertical, and the axis of blade baseplane and boring and milling knife bar is in 12 ° of angles.
Further, the primary clearance of blade is 12 °, and the front clearance of blade is 3 --- 5 °.
Further, further include pressing plate and plate screw, pressing plate is fitted in by plate screw on blade.
The utility model can finish counterbore endoporus and bottom surface position simultaneously, reduce 50% or more the time of tool changing, reduce
To knife time and difficulty, high precision machining improves product quality and performances, can meet the batch machining of counterbore, in addition, increasing
Tip size can be effectively increased cutter head impact resistance, compress blade using briquetting, can effectively prevent lifts, improve processing
Stability.
Description of the drawings
Fig. 1 is 1 preferable overlooking structure diagram of the utility model embodiment；
Fig. 2 is the preferably main structure diagram with size of the utility model embodiment 1；
Fig. 3 is 1 preferable structural schematic diagram of the utility model embodiment；
In figure：Boring and milling knife bar 1, pressing plate 2, plate screw 3, blade 4, blade screw 5, point of a knife 41, blade 42.
Specific implementation mode
The utility model by the following examples the utility model can be made into-step description, however, this practicality
Novel range is not limited to following embodiments.
Embodiment 1：Referring to Fig. 1 --- shown in Fig. 3, a kind of counterbore processing boring and milling cutter, it includes boring and milling knife bar 1,4 and of blade
Blade screw 5, the head sizes of boring and milling knife bar 1 are more than the shaft size of boring and milling knife bar 1, and blade 4 is equilateral triangle structure, boring and milling
It is provided tiltedly with milling flat along head one end in the middle part of the shaft of knife bar 1, the head position that boring and milling cutter bar 1 is located on milling flat is equipped with dress
Cutter groove, blade 4 are mounted on by blade screw 5 in the knife holder slot on 1 head of boring and milling knife bar, and the wherein a line of blade 4 stretches out in
Boring and milling knife bar 1 forms blade 42, and the both ends of blade 42 are point of a knife 41, and blade 42 is vertical with the axis of boring and milling knife bar 1,4 bottom of blade
The axis of plane and boring and milling knife bar 1 is in 12 ° of angles.
Further, the primary clearance of blade 4 is 12 °, and the front clearance of blade 4 is 3 --- 5 °.
Further, further include pressing plate 2 and plate screw 3, pressing plate 2 is fitted in by plate screw 3 on blade 4.
When the utility model is processed, endoporus side wall is first finished to baseplane, then by point of a knife 41 and blade 42 by point of a knife 41
Finish side wall and baseplane size simultaneously.The utility model can finish counterbore endoporus and bottom surface position simultaneously, reduce and change
50% or more the time of knife reduces to knife time and difficulty, and high precision machining improves product quality and performances, can meet counterbore
Batch machining, in addition, increase tip size, cutter head impact resistance can be effectively increased, using briquetting compress blade, can effectively prevent
Only lifts improves the stability of processing.
