Description
Technical field
The utility model is related to a kind of deep hole rough boring head of energy adjust automatically supporting gap, belongs to mechanical manufacturing technology neck
Domain.
Background technology
It is general using heavy boring, right boring, hone or heavy boring, right boring, rolling technology during deep hole machining, for allowance
Scraping tumbling boring head is used the big deep hole of small batch more.
Because deep-hole boring head boring bar stretches out longer, it is impossible to provide rigid support, the branch of boring head Tool in Cutting for Tool in Cutting
Support is to rely on hole machined face within support block to rotate against friction as the strong point and spigot surface, part and support block, often
Several support blocks of processing will wear and tear, and the support block after abrasion will adjust gap in time or change support block, in order to avoid there is size
Unstable, boring head stuck phenomenon, general support block is advisable with interior interporal lacuna in 0.025-0.05mm, therefore adjustment supporting gap is to behaviour
The skill set requirements of workmanship are high, and frequently adjustment or replacing support loses time to increase consumptive material.
The content of the invention
Problem to be solved in the utility model is the problem of support block abrasion is very fast during existing deep hole machining.
In order to solve the above problems, the utility model provides a kind of adjust automatically deep-hole boring head, including boring head body, boring head
The front end of body is provided with cutter hub, and cutter hub is provided with blade, it is characterised in that is provided with plunger rod, plunger rod and sets in the boring head body
There is driving lever, the end of plunger rod is provided with back-moving spring, and the external side of boring head is provided with spring base, and axle is provided between spring base and boring head body
Axial thrust bearing, boring head is provided with tension spring in vitro, and the two ends of tension spring are fixed and connected with spring base, adjustment spring base respectively
Connect；The front end of boring head body is provided with tapered sleeve, and tapered sleeve is externally provided with retainer, tapered roller, and rear end is provided with outside hydraulic fitting, rear end
Side is cased with adapter sleeve；Plunger rod, boring head body, the oil duct in hydraulic fitting are interconnected.
The utility model is support using tapered roller, coordinates tapered sleeve, tension spring to reach adjust automatically supporting gap
Purpose, multiple tapered rollers reach that roller, simultaneously along the cylindrical axial movement of tapered sleeve, can be realized by the active force of retainer, spring
Roller excircle dimension can according to hole size adjust automatically, by hydraulic drive plunger rod, driving lever, retainer when boring head bounces back,
Retainer drives roller to be moved simultaneously to tapered sleeve small end, and roller is cylindrical to be reduced, and boring head exits part.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is simple in construction, easy to operate, practical, and adjust automatically reduces operative employee's skill set requirements, saves replacing
The consumptive material of support, processing dimension is stable, support for rolling frictional resistance it is small.
Brief description of the drawings
Fig. 1 is the front view of adjust automatically deep-hole boring head；
Fig. 2 is the axial view of adjust automatically deep-hole boring head.
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in Figure 1, 2, a kind of adjust automatically deep-hole boring head provided for the utility model, it includes boring head body 1, boring head
The front end of body 1 is provided with cutter hub 12, and cutter hub 12, which is provided with blade 11, boring head body 1, is provided with plunger rod 13, and plunger rod 13, which is provided with, to be dialled
Bar 14, the end of plunger rod 13 is provided with back-moving spring 15, and the outside of boring head body 1 is provided with spring base 6, between spring base 6 and boring head body 1
Provided with axial thrust bearing 5, boring head body 1 is externally provided with tension spring 7, the two ends of tension spring 7 respectively with spring base 6, adjustment bullet
Spring abutment 8 is fixedly connected；The front end of boring head body 1 be provided with tapered sleeve 3, tapered sleeve 3 be externally provided with retainer 2, tapered roller 4 (tapered sleeve 3 it is larger
End is preceding, and small end is rear, and tapered roller 4 is on the contrary, and outside is straight flange), rear end is provided with hydraulic fitting 10, the outside of rear end
It is cased with adapter sleeve 9；Plunger rod 13, boring head body 1, the oil duct 16 in hydraulic fitting 10 are interconnected.
During bore hole, 17 import stage of part boring head, which is placed in lathe and awards oily device and introduce, covers interior, discharges oil circuit pressure, resets
Spring 15 promotes plunger rod 13 to reset, and driving lever 14 leaves retainer 2, and it is same that tension spring 7 promotes retainer 2 to interlock tapered roller 4
When moved to the larger end of tapered sleeve 3, the cylindrical expansion of tapered roller 4 is close to introduce set endoporus and keeps some tension.
Now tapered roller 4 can provide stable rigid support power, the circle that cutter enters behind part 17 for Tool in Cutting
Cone roller 4 follows up simultaneously, and such as machined endoporus is more than when introducing set endoporus promotes retainer 2, tapered roller in tension spring 7
4 continue to the end movement greatly of tapered sleeve 3, and the cylindrical hole size of part 17 that is extended to of tapered roller 4 (is cutting lay on the inside of part 17
171)。
As when inner bore of part, which is less than, introduces set endoporus, under cutter axial feed active force, tapered roller 4 overcomes tension force bullet
The active force of spring 7, tapered roller 4 can be moved to the small end of tapered sleeve 3, and tapered roller 4 is cylindrical to be contracted to the hole size of part 17
Laggard inner bore of part, the purpose of adjust automatically is reached with this.
By hydraulic drive plunger rod 13, driving lever 14, retainer 2 when boring head bounces back, retainer 2 drives tapered roller 4 same
When moved to the small end of tapered sleeve 3, tapered roller 4 is cylindrical to be reduced, and boring head exits part 17.
