Description
Technical field
The utility model relates to bearing replacing technical field more particularly to a kind of oscillating bearing more changing devices.
Background technique
Oscillating bearing is widely used in engineering hydraulic cylinder, forging machine tool, engineering machinery, automation equipment, automobile shock
The industries such as device, water conservancy machinery.Its structure is simpler than rolling bearing, is mainly that the inner ring for having spherical outside surface by one and one have
The outer ring of Internal Spherical Surface forms, and can bear biggish load.Oscillating bearing is generally used for the lower pendulum motion of speed and low speed rotation
Transhipment is dynamic, can also make banking motion within the scope of certain angle.The replacement of oscillating bearing, be oscillating bearing application when often into
A capable procedure.The generally applicable plain bearing of other field is generally dismantled using bearing puller at present, but is drawn
The disassembly that device is not particularly suited for oscillating bearing is pulled out, the installation of oscillating bearing can not be used for.It at present can be especially convenient, not fast
The tool of speed replacement oscillating bearing, the especially replacement of the oscillating bearing on grinding machine, the tool needed is various, and operating process is numerous
Trivial, removal efficiency is low and is easy to damage machinery.
Chinese patent application publication number CN201010555924.X, publication date are on November 24th, 2010, entitled " a kind of
The disassembly installation tool of oscillating bearing and disassembly installation method ", disclose disclose the disassembly installation tool of oscillating bearing a kind of with
Dismantle installation method.But the device needs two components in advance by oscillating bearing connection to remove one, that is, removes joint shaft
The pin shaft and the component fixed with pin shaft on inner ring are held, is then again extracted oscillating bearing from another component with the device.
And on big machinery especially grinding machine, most importantly pin shaft removes and installs for the replacement of oscillating bearing, but the patent
Described in tool can not remove the oscillating bearing pin shaft.
Summary of the invention
In order to overcome the shortcomings in the prior art, providing one kind, can to disassemble and install big machinery special for the utility model
It is the oscillating bearing on grinding machine, and disassembly and installation process is quick, safety, labour-saving oscillating bearing more changing device.
To achieve the goals above, the utility model uses following technical scheme:
A kind of oscillating bearing more changing device, including fixed frame, mobile platform and hydraulic cylinder, the fixed frame are equipped with multiple
Guide rod, the guide rod are equipped with the connecting rod being slidably connected with guide rod, and the connecting rod is fixed with the mobile platform, the liquid
Cylinder pressure includes piston rod and cylinder body, and the cylinder body is connect with fixed frame, and the piston rod is connect with mobile platform；The movement is flat
Platform is equipped with multiple threaded rods and multiple fixation holes, and the fixation hole and threaded rod correspond；In corresponding fixation hole and spiral shell

Dress bar 10 can move axially.It can be positioned and be fixed when pin shaft is installed using mounting rod 10, not need to carry out artificial
Positioning and gripping, reduce labor intensity.When avoiding installation simultaneously, due to operation error, cause the movement of mobile platform 2 to peace
Dress personnel cause to damage, and ensure that the safety of installation personnel.The block 10.1 that end is arranged in avoids mounting rod 10 and pin shaft
It is slid from mobile platform 2, ensure that the safety of personnel and equipment.
The mobile platform 2 is equipped with swivel becket 11, and the swivel becket 11 is rotated with mobile platform 2 by rolling bearing 12
Connection, the connecting rod 5 and swivel becket 11 are fixed；The piston rod 3.1 is rotatablely connected with mobile platform 2.When dismantling pin shaft,
Threaded hole on pin shaft is not necessarily aligned with the threaded rod 6 on mobile platform 2, causes threaded rod 6 that can not screw in threaded hole, at this time
Threaded rod 6 can be made to be aligned with threaded hole with moving in rotation platform 2, be screwed in convenient for threaded rod 6.
The cylinder body 3.2 uses hydraulic oil pump feed.Hydraulic oil pump feed is more convenient and efficient than the replacement of manual fuel feeding, and it is strong to reduce labour
Degree.Hydraulic oil pump feed can adapt to the disassembly scene of the oscillating bearing of eminence or small space, increase the utility model
The scope of application.
When dismantling oscillating bearing using the present apparatus, needs the end cap for the oscillating bearing that will need to dismantle to remove, then pass through
Reserved bolt hole mechanically, fixed frame 1 is bolted on the big machinery for needing to dismantle, lifting can be passed through
Equipment auxiliary is mounted to machine.Mobile platform 2 is aligned to the pin shaft of oscillating bearing.6 end of threaded rod is screwed in pre- on pin shaft
In the threaded hole being adapted to threaded rod 6 stayed, threaded rod 6 is then fixed on mobile platform with two nuts 7 on threaded rod 6
On 2, the piston rod 3.1 of hydraulic cylinder 3 is in stretching state at this time, then gives 3.2 fuel feeding of cylinder body, piston rod 3.1 is retracted, piston
Bar 3.1 drives mobile platform 2 mobile, and mobile platform 2 drives threaded rod 6 mobile, drives pin shaft to extract by threaded rod 6.Pin shaft pulls out
After out, two components connected by oscillating bearing have actually been separated, and two component movements are staggered, at this point, oscillating bearing
Outer ring and one of component are still fixed.It is connect since big machinery oscillating bearing outer ring generally passes through circlip with component, only
Circlip, which need to be removed, just can remove oscillating bearing, complete the disassembly to oscillating bearing.
When oscillating bearing being installed using the present apparatus, first oscillating bearing outer ring is installed on component, pin shaft is passed through into installation
Bar 10 is connected in the present apparatus, then the present apparatus is mounted to machine, and is then directed at two components, can be rotated movement and be put down,
2, make the bearing pin mounting hole of pivot pin alignment mechanically.Starting hydraulic pump gives cylinder body 3.2 fuel feeding later, and piston rod 3.1 stretches out, and drives
Pivot pin is pressed into bearing pin mounting hole by boss 2.1, then screws out mounting rod 10, and the present apparatus is removed from machinery, is finally installed
The end cap of oscillating bearing.
The beneficial effects of the utility model are: oscillating bearing quickly and safely can be dismantled and be installed；Large size can be replaced
The oscillating bearing of equipment；Reduce oscillating bearing disassembly and installation process technical staff's labor intensity.
