Further, two arc pulling plates between two arc pulling plates with after screw bolt seat symmetrically clamping, having easy to observation axis
Hold the gap of situation.By the reserved gap, the changing condition of workpiece in pulling plate can be observed directly, easy to according to bearing
Drawing situation carries out screw rod rotation and adjusts, and overcomes not it is observed that the drawbacks of workpiece working status.
The utility model uses arc pulling plate, and arc pulling plate inner surface fits closely the cylinder of bearing, when ensureing drawing not
Outer framework can be destroyed.Meanwhile the gap between two arc pulling plates is formed into observation window, it can easily observe the shape of workpiece
Condition, overcomes not it is observed that the drawbacks of workpiece working status.
Brief description of the drawings
Fig. 1-the utility model section structure diagram.
Fig. 2-the utility model outline drawing.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1 and Fig. 2, the instrument that the utility model is used to extract bearing from axis is can be seen that from figure, including
The screw bolt seat 2 of screw rod 1 and cylinder, 2 center of screw bolt seat are equipped with threaded hole, and screw rod 1 is connected by threaded hole with screw bolt seat 2.This
Instrument further includes mutually isostructural two arcs pulling plate 3, axis and the installation overlapping of axles of arc pulling plate, the intrados of arc pulling plate with
Bearing top circle side face to be pulled out matches, and two arc pulling plates, 3 inward at both ends is turned down to form parallel arc snap-gauge 4 respectively
（In fan ring-type）；Two card slots are equipped with screw bolt seat outer circumferential surface, and the arc snap-gauge of wherein one end is connected in card slot with by two arcs
Pulling plate is symmetrically clamped with screw bolt seat, and the arc snap-gauge of the other end is used to hook from below（Touch）The ballframe carriage of bearing.Screw rod 1
After screw bolt seat 2, the drive end 11 of screw rod（Illustrate upper end）Backwards to arc pulling plate 3, the other end as with where bearing
Axis contact jaw 12 is between two arc pulling plates 3.
In embodiment, the connection setting of two card slots forms ring-type card slot.So card slot processing in itself and arc snap-gauge with
The installation of card slot is all more convenient.
Further, this instrument further includes a pulling plate stop collar 5, pulling plate stop collar 5 be sleeved on two arc pulling plates, 3 outer surface with
Prevent arc pulling plate 3 from disengaging；I.e. pulling plate stop collar internal diameter matches with arc pulling plate outside diameter.5 upper end of pulling plate stop collar is to varus
Folding forms spacing nosing 6, and spacing nosing 6 is ridden over being taken off on the arc snap-gauge 4 of card slot clamping when preventing pulling plate stop collar 5 from using
Fall.Due to arc pulling plate during the work time, outside active force can be subject to and have the trend outwards disengaged, pulling plate stop collar
Purpose is exactly to maintain the state of arc pulling plate, avoids it from coming off, make arc pulling plate all the time with bearing top circle week good contact, with protect
Demonstrate,prove the good stress of drawing process bearing.
Preferably, the screw rod is equipped with scotch 7 with axis contact jaw 12, axis where scotch diameter is less than or equal to bearing
Diameter.The appearance of scotch, due between scotch and installation axle in drawing there are larger frictional force, therefore even if screw rod revolve
Turn, scotch does not also rotate substantially, avoids and is directly contacted in screw rod rotary course with axial end to the damage of axial end, is had
Protect installation axle to effect.
It is plane that the scotch, which contacts that face with axis, and another side is equipped with circular pit, and screw front end is inserted into pit.It is logical
The design of pit connection structure is crossed, screw rod is inserted directly into pit, simple in structure, easy to pick and place and assemble.
Further, two arc pulling plates between two arc pulling plates with after screw bolt seat symmetrically clamping, having easy to observation axis
Hold the gap of situation（I.e. arc pulling plate radian is less than 180 °, is actually smaller than 90 °, can so not influence the feelings of operation effectiveness
Reduce materials under condition）.By the reserved gap, the changing condition of workpiece in pulling plate can be observed directly, easy to according to axis
Bear situation of pulling out and carry out screw rod rotation and adjust, overcome not it is observed that the drawbacks of workpiece working status.
This instrument application method, i.e., the method extracted bearing from installation axle are as follows：
1）Screw rod is screwed into screw bolt seat by the threaded hole on screw bolt seat first, by scotch and screw shaft contact jaw
Connection.
2）Screw bolt seat and screw rod are put on the mounting shaft, and make the center of stop block alignment installation axle.
3）Arc snap-gauge below two arc pulling plates is hooked into bearing outline border lower face respectively, then rotary screw to conjunction
Right position is put, and the arc snap-gauge of top is just connected in the card slot on screw bolt seat, and pulling plate stop collar finally is sleeved on arc draws
Plate periphery, and spacing nosing is ridden on the arc snap-gauge being clamped with card slot, the assembling i.e. before the drawing of completion instrument at this time.
4）Finally use other instruments（Such as spanner）Rotary screw makes screw rod be moved to close to installation direction of principal axis, due to screw rod
Front end is abutted on the mounting shaft by scotch, and in screw rod rotary course, scotch and arc pulling plate produce relative motion, arc
Pulling plate pulls outward bearing, and most bearing draws out installation axle at last.
The utility model uses arc pulling plate, and arc pulling plate inner surface fits closely the cylinder of bearing, when ensureing drawing not
Outer framework can be destroyed.Meanwhile the gap between two arc pulling plates is formed into observation window, it can easily observe the shape of workpiece
Condition, overcomes not it is observed that the drawbacks of workpiece working status.
Using the arc pulling plate of two splits, pulling plate lower end uses the arc snap-gauge than bearing slightly smaller size, uses this instrument
To hook the ballframe carriage of bearing, using the screw thread on screw bolt seat, screw rod is rotated so that opposite position occurs for arc pulling plate and screw rod
Move, so that bearing be extracted from installation axle.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, can be to this
The technical solution technical scheme is modified or replaced equivalently of utility model, without departing from the objective and model of technical solutions of the utility model
Enclose, it should all cover among the right of the utility model.
