Description
Technical field
The present invention relates to a kind of closing devices, and in particular to a kind of portable oscillating bearing rolling beading device.
Background technique
Oscillating bearing is made of inner ring and outer ring, and oscillating bearing needs oscillating bearing outer ring being fixed on bearing when in use
On seat.Design has V-groove on bearing axis, needs to close up by that side of the V-groove of bearing outer ring when oscillating bearing is installed.
There are two types of current main closing in modes.One is by the way of static pressure, V-groove side is pressed using press machine,
So that it is deformed flange, is pressed on bearing appearance end face, plays the role of fixing bearing.V-groove flange is needed using static pressure mode
Apply a very big external force, the general application that external force is realized using hydraulic press.Structure is complicated for hydraulic press, and cost is very high, fits
Close large batch of production.Hydraulic press machine is huge, is not suitable for open air in-site installation and uses.Another mode is using rotation side
Formula closes up, and a boss is stretched out on rotary body, and boss is pressed in V-groove side by external force, and rotary body rotation turns over V-groove deformation
Side is pressed on bearing appearance end face, plays the role of fixing bearing.The boss and V-groove of the method are sliding friction, friction resistance
Power is very big, closes up very laborious.In addition such method wears rotary body boss very serious, after a period of use after boss abrasion
It cannot play the role of closing in, must just replace rotary body, working service is at high cost.
Chinese patent CN201010578739.2 discloses a kind of closing-in device of joint bearing with spherical surface, including one by rectangle frame
The pedestal that slot bottom seat is formed with the pressing plate connected firmly in rectangle frame slot bottom seat upper end, the upper and lower side of pedestal is provided with acts on axis in opposite directions
The closing in type face pressure plate in the closing in face of holding and double acting idler wheel, closing in type face pressure plate be formed with the consistent groove of bearing closing in face shape,
It passes through the spinning bolt connected thereon and is bonded bearing closing in face from top to bottom, and double acting idler wheel passes through the end connected firmly on pedestal bottom plate
Spherical bearing withstands bearing closing in face both ends from bottom to top, can be manually rotated axis and is closed by spinning bolt, closing in type face pressure plate and spherical surface
The centre bore of bearings connects firmly on the end face between two side wheels.The power generated using rotation bolt is to bearing closing in part
It carries out rolling bearing closing in.The shell nosing device turn over all over closing up by pair of rollers oscillating bearing, closes up by sliding friction, rubs
Power is big, quick abrasion, need to often replace idler wheel, at high cost；And structure is larger, is unfavorable for outfield operation carrying.
Summary of the invention
The purpose of the present invention is to provide a kind of portable oscillating bearing rolling beading devices.
Realize the technical solution of the object of the invention are as follows: a kind of portable oscillating bearing rolling beading device is used for joint
Bearing is fixed on bearing block, and oscillating bearing includes oscillating bearing outer ring, oscillating bearing inner ring and bearing block V-groove, the rolling
Pressing closing device includes positioning seat, steel ball, milled head and fastening screw nut；
The positioning seat includes pedestal and positioning column, and positioning column is set on the base, positioning column pass through oscillating bearing inner ring,
Milled head is threadedly coupled with fastening screw nut, and pedestal both sides are provided with boss, for preventing bearing block from rotating；
The milled head includes six sides of rotation, and six side's upper and lower surfaces of rotation are provided with semi-circular recesses, the semicircle of lower surface
Steel ball is placed between connected in star and bearing block V-groove；
Internal screw thread is arranged in the fastening screw nut inner surface, cooperates with positioning column upper external screw thread；Fastening screw nut lower surface is set

Embodiment
Oscillating bearing reliably, is easily fixed on bearing block by a kind of portable oscillating bearing rolling beading device.Such as
Shown in Fig. 1, Fig. 2, oscillating bearing is made of inner ring and outer ring, and oscillating bearing needs for be fixed on oscillating bearing outer ring when in use
On bearing block.Design has V-groove on bearing axis, needs to carry out by that side of the V-groove of bearing outer ring when oscillating bearing is installed
It closes up.
As shown in figure 3, portable oscillating bearing rolling beading device is broadly divided into positioning seat 5, milled head 7, fastening screw nut 8
With steel ball 6.
As shown in figure 4, positioning seat 5 includes pedestal and positioning column, positioning column is set on the base, and positioning column passes through joint shaft
Inner ring 3, milled head 7 are held, is threadedly coupled with fastening screw nut 8；Pedestal two sides devise two boss 11 of fixed bearing block, can
Guarantee that bearing block is fixed.Positioning seat both ends are respectively arranged with six side of installation and the installation opposite side of convenient wrench force, are closing
When bearings rolling beading, fastening screw nut is pressed on roller-head by spanner, axial pre tightening force is transmitted by steel ball, milled head
To bearing block V-groove side.
As shown in figure 5, milled head is rolling force part, cooperating among milled head with positioning seat, middle section devises six sides,
Force when facilitating rotation.Milled head upper and lower surface devises the first semi-circular grooves, and groove and fastening screw nut above cooperates, ditch
A circle steel ball is placed in slot, is guaranteed that fastening screw nut is not rotated with milled head and rotated, is guaranteed the stabilization of axial pre tightening force.Following
Groove is cooperated by V-groove on closing in steel ball and bearing block.The movement of closing in steel ball is driven by spanner revolving-rolling head, plays rolling
The effect for pressing tightening deforms bearing block V-groove.
As shown in fig. 6, fastening screw nut medium design has internal screw thread and positioning seat upper external screw thread to cooperate.Upper end is provided with simultaneously
Tight six side, lower end design have semi-circular recesses, cooperate with milled head upper half circular groove, and a circle steel ball, steel ball are placed in groove
When upper smearing lubricating grease guarantees milled head rotation, fastening screw nut does not rotate.
In use, first oscillating bearing is put into bearing block 1, positioning seat 5 is then passed through into oscillating bearing inner ring 3, positioning
5 two sides boss 11 of seat are buckled on bearing block 1, prevent bearing block 1 from rotating.Then a circle steel ball 6 is put into bearing block V-groove 4,
Lubricating grease is smeared on steel ball, and milled head 7 is installed.Then a circle steel ball is put into 7 the first semi-circular recesses of upper end 14 of milled head
6.Then fastening screw nut 8 is installed, after fastening screw nut 8 is tightened, axial pre tightening force passes through upside steel ball, milled head, downside closing in steel
Ball is applied to bearing block V-groove close to oscillating bearing outer ring side.Using spanner revolving-rolling head 7, downside closing in steel ball is driven
V-groove on rolling compaction bearing block deforms V-groove under the action of force of rolling friction close to oscillating bearing outer ring side, flange,
It is extruded on oscillating bearing cycle surface.With the deformation of V-groove, the power that closing in steel ball acts on V-groove side is gradually become smaller,
It needs again to be rotated in place fastening screw nut using spanner at this time.After rolling end surface and bearing block end face contacts, need more
It changes the bigger closing in steel ball of diameter and carries out rolling beading again, until oscillating bearing is finally fixed on bearing block 1.
The present invention proposes a kind of rolling beading method of milled head+steel ball, realizes and closes up by force of rolling friction；Design
Milled head, positioning seat, fastening screw nut, realize the positioning of joint bearing block and the application of axial pre tightening force, pretightning force can root
It is adjusted according to actual use.
