Specific embodiment
As shown in Figs 1-4, for the automatic telescopic knife system of boring cutter, including boring cutter body 1, boring cutter 2 is circumferentially arranged in boring cutter body,
It further include the telescope motor 3 being arranged on boring cutter body, telescope motor 3 drives screw rod 5 to rotate by deceleration mechanism 4, and screw rod 5 connects
Boring cutter 2 is arranged on tool apron for the tool apron of boring cutter.Tool apron slot is set on boring cutter body 1, and tool apron can slide in tool apron slot.Flexible electricity
Machine 3 drives screw rod 5 to rotate, so that boring cutter 2 be made to arrive the distance change of 1 centre of gyration of boring cutter body, changes the reaming radius of boring cutter.Boring
When knife 2 works, boring cutter body 1 does forward feed motion while making rotating motion.Telescope motor 3 makes boring cutter 2 during feeding,
The diameter of reaming is gradually increased, and is adapted to the bore hole of taper hole.In this way, not needing to take out boring cutter tune during 2 boring taper hole of boring cutter
Section, and diameter change is smaller between the adjacent stepped hole bored, and the precision of stepped hole is higher.
Screw rod 5 includes the light bar segment 50 for being not provided with screw thread, driven gear 6 is arranged in light bar segment 50, telescope motor 3 passes through
Deceleration mechanism 4 drives driven gear 6 to rotate, and driven gear 6 drives screw rod 5 to rotate.As shown in Figure 1, the output shaft of deceleration mechanism 4
On can be set driving gear 7, driving gear 7 engages transmitting power with driven gear 6.
It slides as Figure 2-3 or on boring cutter body 1 and left tool apron 8 and right tool apron 9 is set, on left tool apron 8 and right tool apron 9
Boring cutter 2 is respectively set.Screw rod 5 includes two thread segments that hand of spiral is identical, screw pitch is different, respectively left-hand thread section 51 and the right side
Thread segment 52.It is connected respectively by left-hand thread section 51 and right-hand thread section 52 between left tool apron 8, right tool apron 9 and screw rod 5；Left tool apron
8, screw rod 5,9 whole slide of right tool apron are arranged 1 on boring cutter body.Here left tool apron 8, right tool apron 9 is intended merely to distinguish two
Tool apron is not left end or the right end that screw rod 5 is centainly arranged in.Left-hand thread section 51 and right-hand thread section 52 also with left-right position without
It closes.Screw rod 5 rotates, and two tool aprons in left and right are mobile to the same direction.Existing boring device, also having setting includes two sections of screw threads
The method of the identical thread segment in direction, but two sections thread segment one is connected with fixing end, one is connected with tool apron, sets on tool apron
Set boring cutter.The every rotation of screw rod one week in this way, the spacing variation between fixing end and boring cutter are the difference of the screw pitch of two sections of thread segments.Boring
Swivel is one week dynamic, and the diameter change in hole is twice of pitch difference, can't reach smaller precision variation.In the utility model,
The tool apron of two boring cutters 2 point-blank, i.e., left tool apron 8 and right tool apron 9 are set.Screw rod rotates one week, left tool apron 8 and the right side
Distance change is the difference of the screw pitch of two sections of thread segments between tool apron 9.The variation of the distance between two boring cutters 2 is exactly the diameter of bore hole
Variation is exactly pitch difference, smaller than the prior art, more accurately.Left tool apron 8 and right tool apron 9 are slidably arranged in tool apron slot.Although
When screw rod rotates, left tool apron 8 and right tool apron 9 need not worry about two respectively to the mobile different distance in the same direction
The centre of gyration line of the center deviation boring cutter body 1 of 2 distance of boring cutter causes reaming not coaxial with foramen primum.Because in the process of bore hole
In, the thickness that two boring cutters 2 cut hole wall is different, and resistance is different, and left tool apron 8 and the whole meeting adjust automatically of right tool apron 9 are in tool apron
Position in slot keeps the resistance being subject to during two 2 reamings of boring cutter identical, so that the thickness for cutting hole wall is equal.
Deceleration mechanism 4 includes output shaft, and driving gear 7 is arranged on output shaft, rotates and sets on left tool apron 8 or right tool apron 9
The intermediate gear 10 engaged with driving gear 7 is set, intermediate gear 10 is engaged with driven gear 6.During the thickness of driving gear 7 is greater than
Between gear 10 thickness, between intermediate gear 10 and driving gear 7 sliding and sliding process in engage always.Driven gear 6 is sliding
It is dynamic to be arranged in light bar segment 50 and rotated together with light bar segment 50.Light bar segment 50 can be set in the centre of screw rod 5 or any one
End.
Long key 53 is arranged in light bar segment 50, and driven gear 6 is slidably arranged on long key 53 and cooperates with long key 53, left tool apron 8
Or gear grooved 11 is arranged in right tool apron 8 position corresponding with intermediate gear 10, driven gear 6 is arranged in gear grooved 11.Left knife
Perhaps setting center tooth race intermediate gear 10 by gear shaft is rotatably arranged on left tool apron 8 or right knife to seat 8 on right tool apron 9
In seat 9, left tool apron 8 or the position corresponding with intermediate gear 10 of right tool apron 9 refer on intermediate gear 10 or center tooth race
Under corresponding position.In this position, driven gear 6 and 10 position of intermediate gear are corresponding, are in meshing state always.Driven tooth
6 are taken turns always in gear grooved 11, so that the left tool apron 8 or right tool apron 9 with setting gear grooved 11 are mobile.Driven gear 6 and spiral shell
It is produced relative sliding between bar 5.Telescope motor 3 can be servo motor, with positive and negative rotation and can rotate lesser angle.
When it is implemented, bore hole mechanism starts, during bore hole, the place of the radius change of reaming, telescope motor 3 is opened
Dynamic, the rotation of 4 output shaft of deceleration mechanism drives driving gear 7 to rotate.Intermediate gear 10 and driven gear 6 is driven to rotate later.Spiral shell
Bar 5 rotates, left tool apron 8 and right tool apron 9 respectively to equidirectional movement, intermediate gear 10 and driven gear 6 with left tool apron 8 or
Right tool apron 9 is mobile.It slides between intermediate gear 10 and driving gear 7, is slided between the light bar segment 50 of driven gear 6 and screw rod 5.
During continuing reaming, the resistance for the hole wall that both sides boring cutter 5 is received is different, to make left tool apron 8 and right tool apron 9 and screw rod 5
Whole position adjust automatically reaches both sides boring cutter 2 and cuts the consistent state of pore wall thickness, guarantees that taper hole or stepped hole are concentric.
Or as shown in figure 4, polished end 50 is arranged between left-hand thread section 51 and right-hand thread section 52.It is arranged on boring cutter body 1
Driving gear 7 is arranged on the output shaft of deceleration mechanism 4 for telescope motor 3 and deceleration mechanism 4, and driving gear 7 and driven gear 6 are nibbled
It closes, the thickness of driving gear 7 is greater than the thickness of driven gear 6, sliding and sliding process between driven gear 6 and driving gear 7
In engage always.In this way, being not provided with intermediate gear 10, structure is simpler.
When it is implemented, telescope motor 3 starts, the rotation of 4 output shaft of deceleration mechanism drives driving gear 7 to rotate.It is driven
Gear 6 rotates.Screw rod 5 rotates, and left tool apron 8 and right tool apron 9 are respectively to equidirectional movement.When continuing reaming, in wall drag
Under effect, left tool apron 8 and right tool apron 9 and screw rod 5 are moved integrally.Driven gear 6 is mobile with screw rod, thus in driving gear
It is slided on 7.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
