Description
Technical field
The utility model is related to field of mechanical technique, more particularly to a kind of ream instrument positioning sleeve.
Background technology
As mechanical processing industry develops, people increasingly pay attention to the precision of machining, and particularly precision optical machinery is set
It is standby, the processing request of precision is particularly paid attention to.Positioner is particularly important during ream, due to bearing shell internal diameter and differ
Cause, causing the diameter of positioner will also change therewith, the utility model proposes a kind of ream positioning sleeve, its ringfeder is 3 half
Formula, can be finely adjusted to the diameter of positioner.
Utility model content
The purpose of this utility model is in order to solve the above-mentioned technical problem, and then to provide a kind of ream instrument positioning sleeve, its
It is simple in construction, it is easy to operate.
The technical solution of the utility model：
A kind of ream instrument positioning sleeve, including：Heart set, ringfeder, turn and clamp nut,
The heart set is axially provided with through hole, and heart set left end end is provided with gear platform, and the outer circumference surface of heart set is male cone (strobilus masculinus), institute
The right-hand member for stating heart set is machined with one section of screw thread, and the male cone (strobilus masculinus) of heart set and the inner conical surface of ringfeder fit；
The ringfeder is three valve body formula structures, and the male cone (strobilus masculinus) that the inwall of each valve body covers with the heart is engaged, each valve body
Two ends outer wall on be equipped with, turn be located at groove in, turn by ringfeder be enclosed on the heart set male cone (strobilus masculinus) on；The fastening spiral shell
Female screw thread for covering male cone (strobilus masculinus) with the heart matches.
Further, the height of the clamp nut and the height sum of ringfeder are less than the height that the heart covers the conical surface.
Further, the conical surface of the heart set and its axle center angulation are 1-5 degree.
The utility model has the advantages that：
The utility model ringfeder uses 3 half formula structures, and ringfeder outer wall is provided with spring groove, make ringfeder each other you
Between connected by spring, while by clamp nut make ringfeder the heart set on move left and right, its external diameter is carried out within the specific limits
Increase reduces, so as to adapt to various bearing shells, its is simple in construction for the utility model, easy to operate.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 profile.
Embodiment
The utility model is described in detail below with reference to accompanying drawing.
A kind of ream instrument positioning sleeve, including：Heart set 1, ringfeder 2, turn 3 and clamp nut 4,
The heart set 1 is axially provided with through hole, and the heart covers 1 left end end and is provided with gear platform, and the outer circumference surface of heart set 1 is outer cone
Face, the right-hand member of the heart set 1 is machined with one section of screw thread, and the inner conical surface of the male cone (strobilus masculinus) and ringfeder 2 of heart set 1 fits；
The ringfeder 2 is three valve body formula structures, and the male cone (strobilus masculinus) that the inwall of each valve body covers 1 with the heart is engaged, each valve
It is equipped with the two ends outer wall of body, turn 3 is located in groove, ringfeder 2 is enclosed on the male cone (strobilus masculinus) of heart set 1 by turn 3；It is described
The screw thread that clamp nut 4 covers 1 male cone (strobilus masculinus) with the heart matches.The height of the clamp nut 4 is less than the heart with the height sum of ringfeder 2
Cover the height of 1 conical surface.
The conical surface of the heart set 1 and its axle center angulation are 1-5 degree.
The male cone (strobilus masculinus) of heart set 1 coordinates with the inner conical surface of ringfeder 2, and end is fastened with clamp nut.Ringfeder 2 is 3 half formula knots
Structure, can cover in the heart and be moved left and right on 1 conical surface, its external diameter increases or reduced within the specific limits, plays tight with inner surface of bearing bush
The effect of closely connected conjunction, clamp nut 4 is held out against forward, and what ringfeder 2 will be tightly rises on Pad radius, to prevent 3 half formula ringfeders 2
Surprisingly come off, turn 3 is wrapped in the annular groove of ringfeder 2.
