Description
Technical field
The present invention relates to machining equipment fields, and in particular to for the boring machine comprehensive process of Boring of Non-circular Piston Pinhole
Main-shaft head structure.
Background technology
Boring of Non-circular Piston Pinhole includes gross porosity, smart hole, annular groove, inner chamfer, outer chamfer, reaming etc. multiple working procedure,
At present since the unilateral maximum effectively offset of boring cutter only has the deflection of 0.06mm or so, certain model boring machine during Boring machine processing
It can only carry out the finishing of a certain procedure.Applicant researches and develops a boring machine comprehensive process main-shaft head structure, is equipped with the change of boring cutter
Body can make the unilateral maximum effectively offset of boring cutter reach more than 1.2mm, adapt to multiple working procedure processing, incorporate technique, can essence
Subtract personnel, improve processing efficiency.
Invention content
The technical problem to be solved in the present invention is to provide a kind of boring machine comprehensive process main-shaft head structure, the unilateral maximum of boring cutter has
Effect offset reaches more than 1.2mm, and stability keeps 2 microns, the multiple working procedure processing of piston pinhole is adapted to, basic
Under the premise of not increasing process time, while complete the wherein multiple tracks such as gross porosity, smart hole, annular groove, inner chamfer, outer chamfer, reaming
Process.
The invention is realized by the following technical scheme：
Boring machine comprehensive process main-shaft head structure runs through the spindle drum of cavity including being horizontally set with, and main shaft is installed in cavity, main to turn
Through hole is set in axis, displacement push rod, the driven connection servo motor in displacement push rod one end, other end connection deformation are equipped in through hole
Body, the deformable body include articulated arm, pushing block, upper deformation block and lower supporting block, and connecting pin connection position is used at articulated arm both ends respectively
Push rod and pushing block are moved, the pushing block other end connects deformation block, upper deformation block and lower supporting block gap setting in pin connection, adopted between gap
The two is connected with a support lever, upper deformation block and lower supporting block are fitted to main shaft end.
The present invention is further improved scheme, and the articulated arm is located in the perforation of main shaft vertical or inclination displacement and sets
It puts.Articulated arm is vertical, tilts postural change, can arbitrarily adjust deflection.
The present invention is further improved scheme, and corresponding position opens up short slot between upper deformation block and lower support block gap, props up
Support lever is installed in short slot, deformation block and lower supporting block in connection.
The present invention is further improved scheme, and servo motor is connect by shaft coupling with screw rod transmission, and feed screw nut's seat is solid
Due in displacer, displacer one end installation bearing, displacement push rod one end is installed in bearing.Servo motor is pushed away with displacement
The drive connection stable structure of bar, is conducive to the guarantee of overall processing stability.
Further improvement project of the invention is that two side position of displacer is equipped with firm bearing, and leading screw both ends install
In firm bearing.The movement of leading screw and displacer is more steady.
Compared with prior art, the present invention with following obvious advantage：
Articulated arm of the present invention persistently elapses pushing block under the propulsion of displacement push rod, and pushing block drives upper deformation block, upper deformation block
With lower supporting block by support lever using lever principle, upper deformation block integrally shifts up, and can generate more than 1.2mm boring cutter lists
The maximum effective offset in side adapts to the production requirement of multi-step process, and its processing stability is in 2 microns.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
As shown in Figure 1, the present invention includes being horizontally set with spindle drum 1 through cavity, main shaft 2 is installed in cavity, in main shaft 2
If through hole, displacement push rod 3, the driven connection servo motor 4 in 3 one end of displacement push rod, other end connection deformation are equipped in through hole
Body, the deformable body include articulated arm 51, pushing block 52, upper deformation block 53 and lower supporting block 54, and 51 both ends of articulated arm are respectively with company
Outbound 55 connects displacement push rod 3 and pushing block 52, and the upper deformation block 53 of 52 other end connecting pin 55 of pushing block connection, upper deformation block 53 is under
54 gap setting of supporting block, corresponding position opens up short slot between upper deformation block 53 and lower 54 gap of supporting block, and support lever 56 is worn
In short slot, deformation block and lower supporting block in connection, upper deformation block 53 and lower supporting block 54 are fitted to 2 end of main shaft.
Servo motor 4 turns one of concrete structure of connection displacement push rod 3：Servo motor 4 passes through shaft coupling 6 and screw
7 are sequentially connected, and feed screw nut 8 is fixed in displacer 9, and 9 one end of displacer is equipped with bearing 10, displacement push rod 3 one
End is installed in bearing 10.In order to make screw, displacer operation more stable, 9 liang of side positions of displacer are equipped with firm bearing
11,7 both ends of leading screw are installed in firm bearing 11.
Servo motor 4 starts, and screw 7 is driven to rotate, and displacer 9 moves right, and displacement push rod 3 is driven to move right,
The articulated arm 51 is located in the perforation of main shaft 2 by being tilted towards vertical direction displacement, and drive affects pushing block 52 to bottom offset, into
And upper deformation block 53 is restrained, due to the lever principle of support lever 56, entire upper change between upper deformation block 53 and lower supporting block 54
Shape block 53 is displaced upwards, and the boring cutter on upper deformation block 53 also generates the center displacement so that the unilateral maximum of boring cutter has
Effect offset reaches more than 1.2mm.
