To achieve these goals, the technical solution adopted in the utility model is:
A kind of blade bearing syndeton of micrometer adjustement boring tool, comprise blade bearing and be arranged on the interior sliding sleeve axle of micrometer adjustement boring tool cutter body, as improvement of the present utility model, the end of described sliding sleeve axle is provided with position limiting structure, and the sliding sleeve axle is connected with described blade bearing by this position limiting structure.
The blade bearing syndeton of above-mentioned a kind of micrometer adjustement boring tool, described position limiting structure comprises and is arranged on the boss on the described sliding sleeve shaft end and is arranged on retainingf key on this boss, and the locating hole on the described blade bearing and the boss of this position limiting structure and retainingf key merga pass one fixture that matches is fixedly connected with the end of described sliding sleeve axle.
The blade bearing syndeton of above-mentioned a kind of micrometer adjustement boring tool, described fixture are hold-down screw.
The blade bearing syndeton of above-mentioned a kind of micrometer adjustement boring tool, the radial clearance angle of described blade bearing is provided with an inclined-plane, and it is large that this inclined-plane becomes from top to bottom gradually in rear angular direction.
The blade bearing syndeton of above-mentioned a kind of micrometer adjustement boring tool, the inclined-plane of described blade bearing are smooth flat.
The beneficial effects of the utility model are: the boss and the connection precision that retainingf key and being connected of blade bearing more effectively improves blade bearing that are located at the sliding sleeve axial end, connect rigidity, strengthen the stability of blade bearing, and be easy to machining control, the design on the relief angle inclined-plane of blade bearing makes cutter blade bearing when bore hole cuts present below the relief angle more many greatly than relief angle superjacent air space with the processing hole wall, so that the iron filings that when cutting produces can drop rapidly in the space of blade bearing and workpiece hole wall, avoid the work in-process iron filings to be squeezed in and produce the workpiece machining surface scratch between the space of blade bearing and hole wall, obtain better Surface Machining precision.

The specific embodiment
Further understand and be familiar with for making architectural feature of the present utility model and the effect reached had, cooperate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1, show the micrometer adjustement boring tool of the blade bearing syndeton that adopts the utility model micrometer adjustement boring tool, this boring cutter comprises cutter body 1, is provided with a through hole 2 that radially extends at this cutter body 1, is provided with micromatic setting 3 in this through hole 2;
End at micromatic setting is connected with a blade bearing 4, micromatic setting 3 comprises adjusting screw(rod) 31, be sleeved on the locating snap ring 32 on this adjusting screw(rod) 31, the dial 33 that is arranged on these adjusting screw(rod) 31 1 ends and is connected with adjusting screw(rod) 31 by locating snap ring 32, and the sliding sleeve axle 35 that is arranged on adjusting screw(rod) 31 other ends and is flexibly connected by a fine-tuning nut 34 and adjusting screw(rod) 31; One end of this sliding sleeve axle 35 is provided with a position limiting structure 36, and sliding sleeve axle 35 is fixedly connected with blade bearing 4 by this position limiting structure 36;
As shown in Figure 2, position limiting structure 36 comprises and is arranged on the boss 361 on sliding sleeve axle 35 ends and is arranged on retainingf key 362 on this boss 361, and the locating hole 41 on the blade bearing 4 and the boss 361 of this position limiting structure 36 and retainingf key 362 merga pass one fixture 37 that matches is fixedly connected with the end of sliding sleeve axle 35.
