Description
Technical field
The utility model belongs to deep hole processing equipment technical field, is specifically related to the adjustable cutter revolution deep hole machining cutter holder support in a kind of gap.
Background technology
Deep hole machining, as an important branch in Machining Technology field, is widely used in aerospace industry, national defense industry, oil exploitation, rock drilling, lathe, automobile and other industries.Arbor support, as a part of deep hole processing system, plays the effects such as support, guiding and vibration damping in deep hole machining process to knife bar.Fit clearance between support set and the knife bar of arbor support has direct impact to the service behaviour of deep hole processing system.Excesssive gap, the support to knife bar and damping effect decline, and knife bar easily vibrates, and especially, in cutter revolution deep hole machining occasion, causes knife bar to produce violent swing, affects the stability of a system and hole crudy; Gap is too small, and knife bar cannot normally move relative to bracket leg support set, in cutter revolution deep hole machining occasion, when serious, can, because spin friction heating produces locking phenomenon, cause system normally to work.
At present, gap between its support set of the arbor support that deep hole processing equipment adopts and knife bar mostly can not be adjusted, after wearing and tearing, can only change, even if there is adjustable function, conventionally be also unidirectional adjustment, operate very inconveniently, adjustment difficulty is larger, has a strong impact on support and the damping effect of arbor support to knife bar.
Utility model content
The purpose of this utility model is to provide a kind of gap adjustable toolbar support for cutter revolution deep hole processing equipment, has solved between the arbor support support set that exists in prior art and knife bar gap non-adjustable or adjust the inconvenient support causing and effectiveness in vibration suppression is poor, the problem of the easy locking of knife bar.
The technical scheme that the utility model adopts is: the cutter revolution deep hole machining cutter holder support that a kind of gap is adjustable, comprise arbor support body, in arbor support body, be provided with the lining of hollow, in lining, be provided with the support set of hollow, the inner side, two ends of lining is provided with internal thread hole, internal thread hole is connected with nut, and nut is arranged on the outside of support set, on nut, be provided with handle, two ends between lining and arbor support body are respectively arranged with rolling bearing, the arranged outside of rolling bearing has bearing (ball) cover, the top of arbor support body is provided with the lubricating oil inlet communicating with bearing.
Feature of the present utility model is also,
Support set adopts nylon or polytetrafluoroethylene (PTFE).
The outer surface of support set is conical, and the inner surface of support set is cylindrical, and sleeve inner surface is the taper shape equating with support set tapering.
The two ends of support set are along the circumferential direction provided with the groove being interspersed.
The beneficial effects of the utility model are:
(1) can adjust in real time the gap value between knife bar and arbor support hole, prevent that gap is non-adjustable or adjust the problem such as support and effectiveness in vibration suppression is poor, the easy locking of knife bar that inconvenience causes;
(2) reasonably gap makes lining not only can do gyration with support set together with cutter, and can make the relative arbor support of knife bar axially move.
(3) stability of knife bar in the course of work is strengthened, the quality of the reliability of cutter drilling rod system and institute's machining hole improves.

In figure, 1. lubricating oil inlet, 2. arbor support body, 3. bearing (ball) cover, 4. nut, 5. support set, 6. lining, 7. rolling bearing, 8. groove.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model provides a kind of gap adjustable cutter revolution deep hole machining cutter holder support, as depicted in figs. 1 and 2, comprise arbor support body 2, in arbor support body 2, be provided with the lining 6 of hollow, in lining 6, be provided with the support set 5 of hollow, the inner side, two ends of lining 6 is provided with internal thread hole, internal thread hole is connected with nut 4, and nut 4 is arranged on the outside of support set 5, on nut 4, be provided with handle, two ends between lining 6 and arbor support body 2 are respectively arranged with rolling bearing 7, lining 6 can be rotated with knife bar with support set 5, not because friction generates heat mutually, the arranged outside of rolling bearing 7 has bearing (ball) cover 3, the top of arbor support body 2 is provided with the lubricating oil inlet 1 communicating with bearing 7.
As shown in Figure 3, the outer surface of support set 5 is conical, and the inner surface of support set 5 is cylindrical, and lining 6 inner surfaces are the taper shape equating with support set 5 taperings.Support set 5 is packed into by the large end of lining 6 endoporus.
Support set 5 adopts nylon or polytetrafluoroethylene (PTFE), and nylon or polytetrafluoroethylene (PTFE) support set, in the time being subject to External Force Acting, corresponding plastic deformation can occur, and this plastic deformation causes tightening or loosening of the interior hole dimension of support set.Utilize the character of its stress deformation to reach the object that regulates knife bar and support set gap.Simultaneously nylon or polytetrafluoroethylene (PTFE) are cheap, economical and practical, easily processing, utilize adjusting nut adjustment, lock convenient and swift.
The two ends of support set 5 are along the circumferential direction provided with the groove 8 being interspersed, and these grooves 8 make support set in the time of turn adjusting nut have change in size radially.
The inner side, two ends of lining 6 is provided with internal thread hole, and internal thread hole is connected with nut 4, on nut 4, is provided with handle.Being rotatably connected on the handle on nut 4, there is plastic deformation in nylon or polytetrafluoroethylene (PTFE) support set 5, adjustable knife bar and support set 5 gaps.
Implementation process of the present utility model is: when knife bar feeding, vibration chip removal, between meeting and arbor support, produce relative motion.As shown in Figure 2, lining 6 does with support set 5 taper that tapering is identical, by regulating adjusting nut 4 to make arbor support hole inner support cover that plastic deformation occur, just can change the matching relationship between lining and support set, support set 5 and knife bar.Thereby guarantee normally carrying out of processing, improve crudy: when gap is too small between knife bar and support set 5, suitably adjusting nut is screwed out, gap suitably can be increased, prevent from when knife bar from doing axial relative motion with respect to arbor support being stuck to the right; In the time that the gap between knife bar and hole is larger, suitably adjusting nut is screwed in left, gap suitably can be reduced, improve support performance, reduce the extensional vibration of drilling rod, support set is rotated together with knife bar.
Between lining 6 and arbor support body 2, rolling bearing 7 is installed, turn nut 4 adjusting plays are rotated knife bar together with support set 5, reduce the caloric value that produces because of friction between knife bar and support set 5, improve support performance.
As shown in Figure 3, have groove 8 on support set 5, these grooves 8 have met adjusting nut and have screwed in the radial dimension variation of support set 5 in back-out process, thereby reach the object of adjusting play.
