Description
Technical field
The present invention relates to machining equipment field, be particularly used 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, essence hole, annular groove, interior chamfering, outer chamfering, reaming etc. multiple working procedure,
The deflection of about 0.06mm, therefore certain model boring machine is only had due to the boring cutter effective side-play amount of monolateral maximum at present during Boring machine processing
The polish of certain one procedure can only be carried out.Applicant researches and develops a boring machine comprehensive process main-shaft head structure, the change of equipped boring cutter
Body can make the boring cutter effective side-play amount of monolateral maximum reach more than 1.2mm, adapts to multiple working procedure processing, incorporates technique, can essence
Subtract personnel, improve working (machining) efficiency.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of boring machine comprehensive process main-shaft head structure, and the monolateral maximum of boring cutter has
Effect side-play amount reaches more than 1.2mm, and stability keeps 2 microns, adapts to the multiple working procedure processing of piston pinhole, substantially
On the premise of not increasing process time, complete the wherein multiple tracks such as gross porosity, essence hole, annular groove, interior chamfering, outer chamfering, reaming simultaneously
Operation.
The present invention is achieved through the following technical solutions:
Boring machine comprehensive process main-shaft head structure, including being horizontally set with the spindle drum running through cavity, installs main shaft, in main shaft in cavity
If through hole, equipped displacement push rod in through hole, the driven connection in displacement push rod one end servomotor, the other end connects deformable body,
Described deformable body includes articulated arm, pushing block, upper deformation block and lower bracer, and articulated arm two ends connect displacement with connecting pin respectively and push away
Bar and pushing block, pushing block other end connecting pin connects upper deformation block, upper deformation block and lower support block gap and arranges, uses one between gap
Both are connected by support lever, and upper deformation block and lower bracer are fitted to main shaft termination.
The further improvement project of the present invention is, it is vertical or tilt displacement and set that described articulated arm is positioned at the perforation of main shaft
Put.Articulated arm is vertical, tiltler bit map, can arbitrarily adjust deflection.
The further improvement project of the present invention is, between upper deformation block and lower support block gap, correspondence position all offers short slot,
Support lever is installed in short slot, deformation block and lower bracer in connection.
The further improvement project of the present invention is, servomotor is connected with screw rod transmission by shaft coupling, and feed screw nut's seat is solid
In displacer, bearing is installed in displacer one end, and displacement push rod one end is installed in bearing.Servomotor pushes away with displacement
The drive connection Stability Analysis of Structures of bar, the beneficially guarantee of overall processing stability.
The present invention further improvement project is, displacer two side position is provided with firm bearing, and leading screw both ends install
In firm bearing.The movement of leading screw and displacer is more steady.
The present invention compared with prior art, has a following obvious advantage:
Articulated arm of the present invention, under the propelling of displacement push rod, persistently elapses pushing block, and pushing block drives upper deformation block, upper deformation block and under
Bracer utilizes lever principle, upper deformation block entirety to shift up by support lever, can produce more than 1.2mm boring cutter monolateral
Big effectively side-play amount, adapts to the Production requirement of multi-step process, and its processing stability is at 2 microns.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
As it is shown in figure 1, the present invention includes being horizontally set with the spindle drum 1 running through cavity, cavity is installed main shaft 2, in main shaft 2
If through hole, equipped displacement push rod 3 in through hole, the driven connection in displacement push rod 3 one end servomotor 4, the other end connects deformation
Body, described deformable body includes articulated arm 51, pushing block 52, upper deformation block 53 and lower bracer 54, and articulated arm 51 two ends are respectively with even
Pin 55 connects displacement push rod 3 and pushing block 52, and pushing block 52 other end connecting pin 55 connects upper deformation block 53, upper deformation block 53 and under
Propping up bracer 54 gap to arrange, between upper deformation block 53 and lower bracer 54 gap, correspondence position all offers short slot, and support lever 56 is worn
Being contained in short slot, deformation block and lower bracer in connection, upper deformation block 53 and lower bracer 54 are fitted to main shaft 2 termination.
Servomotor 4 turns one of concrete structure connecting displacement push rod 3: servomotor 4 is by shaft coupling 6 and screw mandrel
7 are in transmission connection, and feed screw nut 8 is fixed in displacer 9, and displacer 9 one end is provided with bearing 10, displacement push rod 3 one
End is installed in bearing 10.More stable in order to make screw mandrel, displacer run, 9 liang of side positions of displacer are provided with firm bearing
11, leading screw 7 both ends are installed in firm bearing 11.
Servomotor 4 starts, and drives screw mandrel 7 to rotate, and displacer 9 moves right, and drives displacement push rod 3 to move right,
