Abstract
The present invention relates to a kind of processing methods of deep hole, belong to drilling method.The processing method of deep hole of the present invention is combined using the tooling and common driller for carrying amplitude, by to frequency and amplitude and empennage frame material, radial drill apparatus adaptability designs, the drill mode of multiple feed is not only greatly reduced, increase the service life of drill bit, it machined the deep hole for meeting index request, achieve the effect that as using Five-axis NC Machining Center processing empennage frame, meet the requirement of scientific research and development, reduce manufacturing cost, the tooling has the function of shaking auxiliary bore hole, by drilling operating by original 24 times, it reduces to 12 times, originally 4 axial holes of processing need 30 minutes, only need 7 minutes now, and dimensional accuracy and surface quality are far superior to existing processing method.
Description
Technical field
The present invention relates to a kind of processing methods of deep hole, belong to drilling method.
Background technology
Part empennage frame is steel thin-wall revolving body in certain rocket projectile, as shown in Fig. 2, length is 480mm, tensile strength is
Rm >=560MPa, elongation percentage are A >=15%, and outer wall has four groups of group of bumps being axially distributed, and every group of group of bumps is by six circumference point
Cloth convex block is constituted, and each convex block of four groups of group of bumps distinguishes axial alignment, is needed on four convex blocks of every axial alignment each
Bore a mutually coaxial hole.If using four convex blocks of every axial alignment as a hole machined, the draw ratio in the hole is
40：1, belong to the scope of deep hole machining, need using the Five-axis NC Machining Center with larger stroke, bore cutter is cooled down using center
Tool is completed, but is improved device requirement and increased manufacturing cost.Or it needs to carry out brill guiding using plain radial drilling equipment
Hole-brill-expansion-hinge often processes 24 holes, needs tool changing 24 times, and can't fully meet the roughness requirements manufacturing cycle in hole
It is long, high labor cost.
Invention content
When processing the bigger deep hole of processing major diameter the purpose of the present invention is to solve conventional borehole technique, there is processing
The problems such as cost is higher, processing technology is complicated, and a kind of processing method of deep hole is provided.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of processing method of deep hole of the present invention, is as follows：
The first, the tooling of included amplitude is installed into radial drill main shaft tapered sleeve, tooling can jointly be revolved with radial drill main shaft
Turn, drill bit is changed to be fitted into tooling by being directly loadable into radial drill tapered sleeve.It drills in radial drill top plate, and by consolidating in tooling
Rationed marketing is inserted so that fixed pin cannot be rotated but can be moved up and down；
The second, the type of cooling is still that outside cools down, and is selected in the position in interrupted hole；
Third, setting rotating speed 100-125r/min, using the half of the axially directed hole length of original drill bit to overall length,
Diameter stays the allowance of 0.1mm；
4th, drill speed is improved to 1000-1250r/min, the upper limit of proximity device rotating speed, drilling to finished size.
Wherein, the tooling of amplitude, including taper shank and fixed pin are carried；Taper shank is Mohs corresponding with radial drill machine spindle
No. 4 taper shanks drill in rocking arm drilling equipment top plate；Fixed pin is fixed with drilling machine, and can be moved up and down with lathe spindle, with main shaft
The synchronous adjustable amplitude vibration of rotation, matches with the amount of feeding of main shaft.
Advantageous effect
The processing method of deep hole of the present invention is combined using the tooling and common driller for carrying amplitude, by frequency and shaking
Width and empennage frame material, the design of radial drill apparatus adaptability, are not only greatly reduced the drill mode of multiple feed, increase brill
The service life of head, machined the deep hole for meeting index request, reach as using Five-axis NC Machining Center processing empennage frame
Effect, meet the requirement of scientific research and development, reduce manufacturing cost, the tooling have the function of shake auxiliary bore hole, will bore
Hole process is reduced by original 24 times to 12 times, and originally 4 axial holes of processing need 30 minutes, only need 7 minutes now,
And dimensional accuracy and surface quality are far superior to existing processing method.
Description of the drawings
Fig. 1 is in the method for the present invention using the tool structure schematic diagram of included amplitude；
Fig. 2 is the structural schematic diagram that the method for the present invention processes empennage frame product；
In figure, 1- taper shanks, 2- fixed pins.
Specific implementation mode
Present disclosure is further described with reference to the accompanying drawings and examples：

Rationed marketing is inserted so that fixed pin cannot be rotated but can be moved up and down；
The second, the type of cooling is still that outside cools down, and is selected in the position in interrupted hole；
Third, setting rotating speed 100-125r/min, using the half of the axially directed hole length of original drill bit to overall length,
Diameter stays the allowance of 0.1mm；
4th, drill speed is improved to 1000-1250r/min, the upper limit of proximity device rotating speed, drilling to finished size.
Wherein, the tooling of amplitude is carried, as shown in Figure 1, including taper shank 1 and fixed pin 2；Taper shank is and rocking arm drilling equipment master
Axis No. 4 taper shanks of corresponding Mohs, drill in rocking arm drilling equipment top plate；Fixed pin is fixed with drilling machine, and can be on lathe spindle
Lower movement, the adjustable amplitude synchronous with main shaft rotation vibration, matched with the amount of feeding of main shaft, vibration can cleaning hole intraclast,
It prevents from scratching hole wall, ensures the roughness requirements of hole wall.Frequency and amplitude and empennage frame material, rocking arm drilling equipment are adapted,
Increase in drilling with being improved.
