Description
Technical field
The present invention relates to a kind of dynamic tool apron, more particularly to a kind of interior hole machined dynamic tool apron.
Background technology
Many new special Shape Parts are increasing, at the same multiple parts be integrated into single part trend it is increasingly bright
It is aobvious.Currently used processing technology means can not meet these new process requirements, such as：1st, Ф 75X80-300's
In cylinder hole, drill inside-out；2nd, in Ф 75X80-300 cylinder hole, milling blind hole keyway；3rd, in Ф 75X80-300
Cylinder hole in, the helix of the big pitch of milling, inventor is frequently run onto hole and added in the practice of long-term field of machining
Work problem, need outwards to bore stepped hole, counter sink from inwall in particularly deeper hole.The milling key groove in blind hole.In hole
The helicla flute of milling bull.And current manufacturing process can not realize that cutter is cut in hole.If reach above-mentioned requirements, it is necessary to have one
Minitype motivation head clamps cutter, stretches into hole, and dynamic transmission channel, rotates cutter, can make to be processed into reality.On
The problem of stating, which is needed badly, to be resolved.
The content of the invention
It is an object of the invention to provide a kind of interior hole machined dynamic tool apron, solves shortcoming existing for prior art.
The present invention adopts the following technical scheme that realization：
A kind of interior hole machined dynamic tool apron, the dynamic tool apron have a tool rest body, and the tool rest body is connect by knife tower
Mouth is connected with machine power knife tower, it is characterised in that a power transmission shaft, the biography are vertically provided with tool rest body
One end of moving axis is provided with needle bearing, and middle part is provided with deep groove ball bearing, and the other end is provided with synchronous toothed belt wheel, described same
Step flute profile belt wheel is connected by timing belt with unit head assembly, and the unit head assembly is provided with knife by trip bolt
Tool.
Further, the knife tower interface is BMT interfaces or VDI interfaces.
The method have the benefit that：Successfully solve the process difficulties of inwall deep hole machining, filled up the country
One blank of machining, is transmitted using synchronous cog belt, processes the depth in hole during fabrication than the knot of other gear transmission
Structure is simple, not stall, and length-flexible is controllable.Greatly reduce lubricating requirement.The present apparatus is compact-sized, can stretch into the holes of Ф 75
Freely process.Unit head assembly 7 uses high-precision angular contact ball bearing, back-to-back installation, the main axle structure with machining center
It is similar.It is mini small-sized main shaft.Paper-cutting machine is locked using compact rear pull type.When cutter turns round, axially and radially jump
It is dynamic to control in 0.005mm.Thus part to be processed precision is high, cutter life length, is that preferably interior hole machined is special dynamic
Power tool rest.
Brief description of the drawings
Fig. 1 is the profile of the present invention.
Fig. 2 is the structure chart of final drive shaft.
Fig. 3 is the schematic diagram of internal keyway processing technology.
Fig. 4 is the schematic diagram of inner spiral groove processing technology.
Embodiment
By the following description to embodiment, it will more contribute to public understanding of the invention, but can't should be by Shen
Given specific embodiment of asking someone is considered as the limitation to technical solution of the present invention, any definition to part or technical characteristic
Be changed and/or make form to overall structure and immaterial conversion is regarded as what technical scheme was limited
Protection domain.
A kind of interior hole machined dynamic tool apron, the dynamic tool apron have a tool rest body 1, and tool rest body 1 passes through knife tower
Interface（BMT interfaces or VDI interfaces）It is connected with turning center machine power knife tower, is arranged in vertical in tool rest body 1
There is a power transmission shaft 2, one end of power transmission shaft 2 is provided with needle bearing 3, and the middle part of power transmission shaft 2 is provided with deep groove ball bearing 4, passes
The other end of moving axis 2 is provided with synchronous toothed belt wheel 5, and synchronous toothed belt wheel 5 passes through timing belt 6 and the phase of unit head assembly 7
Even, cutter 9 is provided with by trip bolt 8 on unit head assembly 7.
The brief introduction of work principle of the present invention：Tool rest body 1 passes through specific knife tower interface（BMT, VDI interface）With lathe
Power cutter tower is connected, and power transmission shaft 2 is fixed in tool rest body 1 with needle bearing 3 and two deep groove ball bearings 4.Timing belt
Wheel 5 is fastened on the end of power transmission shaft 2 with 4-M4 screws.Power transmission shaft 2 is rotated, and power is sent to unit head by timing belt 6
Assembly 7, band cutter 9 carry out machining.Trip bolt 8 is used for fixing unit head assembly 7, to increase its rigidity, ensures to add
Work is steady, improves the finish of finished surface.The present apparatus using timing belt because transmitted, and the depth of workpieces processing is in manufacturing process
In be easily controlled, the equipment mechanism is compact, can stretch into the holes of Ф 75 and freely process.Unit head assembly 7 uses high-precision angle
Contact ball bearing, cutter rotation are radially, axially beated small, and part to be processed geometric accuracy is high, and surface smoothness is good, and cutter uses
Long lifespan, it is hole machined spcific power tool rest in preferable, is processed in not less than the holes of Ф 75, the depth in hole is made as requested
Make, typically not super 300m, parts use standard component such as bearing, timing belt etc., are easy to purchase.
The description of the process of hole machined in three kinds of differences：
Fig. 1：From it is interior drill outward when, machine tool chief axis clamping workpiece, in C axle braking states, X and Z axis are only moved, by cutter
It is moved at processed hole, starts dynamic tool apron, coordinates X-axis feeding, you can complete.
Fig. 2：When dowel hole is closed in milling, when width of keyway is equal to milling cutter diameter, C axles are fixed, and X-direction is retreated
Knife, along Z axis feed, you can complete keyway milling.Now keyway is flat.If width of keyway be more than milling cutter diameter, it is necessary to
Multiple feed is completed, it is necessary to want C axles and X-axis linkage, to complete back and forth along Z axis.Now keyway bottom is arc.
Fig. 3：During milling inner spiral groove, X-direction enters withdrawing, C axles and Z-axis linkage, completes the milling that inner spiral groove is closed in closing
Cut.
Processing need to change different cutters according to different requirements above.
Certainly, the present invention can also have other various embodiments, in the case of without departing substantially from spirit of the invention and its essence,
Those skilled in the art can be made according to the present invention it is various it is corresponding change and deformation, but these it is corresponding change and
Deformation should all belong to the protection domain of appended claims of the invention.
