Ask very high, misoperation will lead to press fitting rear bearing and rotate not flexible or even stuck motionless, initiation engine failure.
Existing technology of pressure mounting scheme is, after pressing bearing outer ring enters bore, using liquid nitrogen frozen axle sleeve, then
Axle sleeve is packed by hand the inner ring of bearing.With the inner ring that be packed into bearing after liquid nitrogen frozen axle sleeve in time, otherwise at a temperature of axle sleeve
Just be difficult to pack into after drop, whether axle sleeve is attached to position entirely with the experience of operator, when there is assembly is not in place to lead to phenomenon of doing over again,
In addition liquid nitrogen slightly misoperation can also frostbite operator.
Summary of the invention
The technical problem to be solved by the present invention is to be directed to the above-mentioned deficiency of the prior art, the present invention provide it is a kind of without using
Liquid nitrogen frozen axle sleeve can guarantee that axle sleeve is pressed precision, safe and practical engine rotation gear bush press-fitting tool.
The technical scheme is that a kind of engine rotation gear bush press-fitting tool, including be used to support in bearing
The cushion block of circle and pressure head for location and installation axle sleeve, the pressure head lower end is respectively equipped with positioning convex platform, may pass through the axis
The guide rod of the centre bore of set is coaxially arranged structure between the pressure head and the positioning convex platform, guide rod, described
Cushion block upper end be equipped with support rim, the pilot hole for guiding the guide rod movement is equipped in the cushion block, it is described
It is coaxially arranged structure between cushion block and the support rim, pilot hole.
As a further improvement, the positioning convex platform is ring structure, accommodating chamber is equipped in the positioning convex platform.
Further, the guide rod, which is connected through a screw thread, is installed on the accommodating chamber bottom.
It further, is spherical structure at the top of the pressure head.
Further, described guide rod one end is equipped with the first guide part.
Further, be equipped with multiple vacuum sucking holes through the positioning convex platform in the pressure head, it is multiple described in it is true
Suction hole is evenly arranged on the pressure head around the axle center of the pressure head.
Further, the support rim is ring structure, and the internal diameter of the support rim is less than the diameter of the axle sleeve.
Further, the cushion block upper end is additionally provided with the second guide part for guiding installation gear.
Beneficial effect
Compared with prior art, the present invention having the advantage that are as follows: guide guide rod movement to be pressed axle sleeve by pilot hole
To bearing inner race, axle sleeve can be accurately pressed into bearing inner race, guarantee that axle sleeve position degree and bearing rotate flexibility, product matter
It measures, high production efficiency, while the security risk of liquid nitrogen frostbite operator being avoided to occur, it is safe and practical.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Wherein: 1- bearing inner race, 2- cushion block, 3- axle sleeve, 4- pressure head, 5- positioning convex platform, 6- centre bore, 7- guide rod, 8-
Support rim, 9- pilot hole, 10- accommodating chamber, the first guide part of 11-, 12- vacuum sucking holes, 13- gear, the second guide part of 14-.
Specific embodiment
The present invention is described further for specific embodiment in reference to the accompanying drawing.
Refering to fig. 1, a kind of engine rotation gear bush press-fitting tool, 2 He of cushion block including being used to support bearing inner race 1
For the pressure head 4 of location and installation axle sleeve 3,4 lower end of pressure head is respectively equipped with positioning convex platform 5, the centre bore 6 that may pass through axle sleeve 3 is led
It is coaxially arranged structure between pressure head 4 and positioning convex platform 5, guide rod 7 to bar 7,2 upper end of cushion block is equipped with support rim 8, pad
It is equipped with the pilot hole 9 for guiding guide rod 7 to move in block 2, is coaxially arranged between cushion block 2 and support rim 8, pilot hole 9
Structure；The course of work of the invention are as follows: axle sleeve 3 is inserted in guide rod 7 and is adjacent to positioning convex platform 5, pressure head 4 is moved downward, led
It is inserted into pilot hole 9 to bar 7, pilot hole 9 guides guide rod 7 to move, and axle sleeve 3 is pressed into bearing inner race 1 by pressure head 4；By leading
It guides the movement of guide rod 7 that axle sleeve 3 is pressed into bearing inner race 1 to hole 9, axle sleeve 3 can be accurately pressed into bearing inner race 1, be protected
It demonstrate,proves 3 position degree of axle sleeve and bearing rotates flexibility, good product quality, high production efficiency, while avoiding liquid nitrogen frostbite operator's
Security risk occurs, safe and practical.
Positioning convex platform 5 is ring structure, is equipped with accommodating chamber 10 in positioning convex platform 5, guide rod 7, which is connected through a screw thread, to be installed on
10 bottom of accommodating chamber is convenient for changing pressure head 4 or guide rod 7, avoids leading to entire tooling report due to pressure head 4 or guide rod 7 damage
It is useless, save use cost；Accommodating chamber 10 can be contained in a small amount of deformation of press fitting process bottom bracket axle 3, go on smoothly press fitting, together
When, ring structure reduces the contact area of positioning convex platform 5 Yu 3 top surface of axle sleeve, improves the positioning accuracy to axle sleeve 3, convex
The lower pressure stepless action of platform 5 guarantees the stability of press fitting in 3 periphery of axle sleeve.
It is spherical structure at the top of pressure head 4, when pressure head 4 is installed on pressing machine, pressure head 4 has certain floating space, protects
Demonstrate,prove centering press fitting；7 one end of guide rod is equipped with the first guide part 11, and guide rod 7 can be made to facilitate into pilot hole 9, improve and import
Effect.
Multiple vacuum sucking holes 12 through positioning convex platform 5 are equipped in pressure head 4, multiple vacuum sucking holes 12 surround the axis of pressure head 4
The heart is evenly arranged on pressure head 4, by avoiding axle sleeve 3 from falling to 12 vacuumizing and adsorbing axle sleeve 3 of vacuum sucking holes.
Support rim 8 is ring structure, and the internal diameter of support rim 8 is less than the diameter of axle sleeve 3, avoids bearing inner race 1 hanging
It is pressed and bearing inner race 1 is caused to be displaced with roller, meanwhile, support rim 8 also limits the depth of the pushing of axle sleeve 3, guarantees
Axle sleeve 3 is press-fit into place, and 2 upper end of cushion block is additionally provided with the second guide part 14 for guiding installation gear 13, can be convenient to gear
13 carry out location and installation, improve production efficiency.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, is not taking off
Under the premise of from structure of the invention, several modifications and improvements can also be made, these all will not influence the effect that the present invention is implemented
And patent practicability.
