Description
Technical field
The present invention relates to machine tool field, more particularly to a kind of micrometer adjustement boring tool based on lever construction.
Background technology
Existing domestic and international right boring unit is mostly realized finely tuning using the precision-fit of screw thread pair, this complex structure,
Manufacture difficulty is high, and the control of manufacturing process intermediate gap requires high, and after easily causing assembling, screw thread auxiliary air gap is excessive, adjusts chi
Big etc. the defect in very little unstable and backhaul gap；And it is this to use modular organization more, there is certain requirement to structure space,
Cause, when bore size is smaller, to realize that difficulty is big in structure；Other this structural fittings are more, and spare and accessory parts required precision makes work
Sequence is very high, and the production cycle is long, causes that such right boring unit cost is high, and the market competitiveness is weaker.
The small cutter holder of adjustable structure for being additionally based on the small cutter holder standards of standard ISO and manufacturing, comes real by screw top boring cutter cutter hub
Now adjust, it is impossible to accurately adjust size, because screw carrys out locating surface jack-up, locating surface is not fitted with boring cutter cutter hub,
Cause positioning unreliable, the low shortcoming of rigidity.
The content of the invention
The technical problem to be solved in the present invention is：A kind of simple structure is provided, manufacture is easily micro- based on lever construction
Adjust boring cutter.
For the technical scheme of the use that solves the above problems is：Micrometer adjustement boring tool based on lever construction includes blade, cutter holder, knife
Body, rotating shaft and adjustment structure, blade are connected with cutter holder, and cutter holder is connected by rotating shaft with cutter hub, and adjustment structure can drive cutter holder
Rotate to change the distance of blade and cutter hub center line around the shaft.
It is further：Adjustment structure includes two regulating bolts and two regulation conical surfaces, regulating bolt and the regulation conical surface
Center line be each perpendicular to the side of cutter holder, two regulation conical surfaces are arranged on cutter holder and are located at rotating shaft both sides, regulation respectively
Bolt is threadedly coupled with cutter hub, and regulating bolt includes conical section, two conical sections of regulating bolt respectively with the regulation conical surface
Contact.
It is further：Be provided with cutter holder groove on cutter hub, cutter holder be located in cutter holder groove and with the sidewall contact of cutter holder groove.
It is further：The cutter hub of cutter holder groove both sides is respectively two cell walls, and regulating bolt includes position portion, adjusts spiral shell
Bolt is threadedly coupled with a cell wall, and position portion inserts the location hole of another cell wall.
It is further：Scale is provided with least one regulating bolt, is set in position corresponding with scale on cutter hub
There is scale marker.
The beneficial effects of the invention are as follows：The present invention realizes fine setting by the overall rotation of cutter holder, does not use screw thread pair
Precision-fit realizes fine setting, and simple structure, manufacture facility installs reliable.Degree of regulation of the present invention is high, up to μ class precisions.It is logical
Blade can be adjusted quickly the size for needing to cross the present invention, so that improve production efficiency, saves production cost.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
Micrometer adjustement boring tool based on lever construction includes blade 4, cutter holder 3, cutter hub 1, rotating shaft 9 and adjustment structure, blade 4 and knife
Folder 3 is connected, and cutter holder 3 is connected by rotating shaft 9 with cutter hub 1, and adjustment structure can drive 9 rotations around the shaft of cutter holder 3 to change blade 4
With the distance of the center line of cutter hub 1.
The present invention realizes fine setting by the rotation of the entirety of cutter holder 3, and the precision-fit of screw thread pair is not used to realize fine setting,
Simple structure, manufacture facility installs reliable.
Adjustment structure drives cutter holder 3, and 9 modes for rotating can have various around the shaft.For example as shown in figure 1, adjustment structure bag
Two regulating bolts 10 and two regulation conical surfaces 2 are included, regulating bolt 10 is each perpendicular to cutter holder 3 with the center line of the regulation conical surface 2
Side, two regulation conical surfaces 2 are arranged on cutter holder 3 and are located at the both sides of rotating shaft 9 respectively, and regulating bolt 10 connects with the screw thread of cutter hub 1
Connect, regulating bolt 10 includes conical section 8, two conical sections of regulating bolt 10 8 are contacted with the regulation conical surface 2 respectively.Regulation
When, a regulating bolt 10 screws in cutter hub 1, and the conical section 8 of the regulating bolt 10 is the powered rotation of cutter holder 3；Another tune
Section bolt 10 screws out cutter hub 1, conical section 8 is departed from the regulation conical surface 2, is that space is conceded in the rotation of cutter holder 3.Two after the completion of regulation
The conical section 8 of individual regulating bolt 10 is contacted with two regulation conical surfaces 2 again, cutter holder 3 is fixed again.Regulation knot of the invention
Structure has degree of regulation higher, up to μ class precisions.
Can be provided with cutter holder groove 6 on cutter hub 1, cutter holder 3 be located in cutter holder groove 6 and with the sidewall contact of cutter holder groove 6.This
Invention conical section 8 is contacted with the regulation conical surface 2, therefore cutter holder 3 understands the power of the regulated axis direction of bolt 10, cutter holder 3 and knife
The sidewall contact of clip slot 6 can balance the power, improve the life-span of cutter holder 3.
