Description
Technical field
It the utility model is related to speed changer production auxiliary tool, more particularly to a kind of quick press mounting gearbox jackshaft part
Device.
Background technology
Automobile gearbox intermediate shaft portion dress process is more complicated, and jackshaft is put into implementation third gear tooth on positioning base first
Wheel press fitting, third gear snap ring is caught in using clasp forceps；Then it is pressed fourth gear, fourth gear snap ring is caught in using clasp forceps；Then turn over
Turn jackshaft, be pressed five shelves gears, replace positioning sleeve；It is pressed the fore bearing inner ring of jackshaft, overturns jackshaft again, is pressed
Bearing inner race after jackshaft.
Whole press fitting process beat is long, repeatedly overturns there are jackshaft and switches positioning sleeve repeatedly, switching process is easy
Collide with product the problem of, influence gearbox assembling quality.
The content of the invention
The purpose of this utility model is to provide a kind of device of quick press mounting gearbox jackshaft part, by first to tooth
Wheel, bearing inner race class part positioned, by the cooperation of press and frock by gear press mounting in place so that press fitting process is not required to
Jackshaft, switching positioning sleeve are overturn, press fitting is efficient, and press-fit effect is good.
The utility model is achieved through the following technical solutions above-mentioned purpose.A kind of quick press mounting gearbox jackshaft part
Device, including base, the centre of base are provided with tapped through hole, adjustment spiral shell are provided with tapped through hole, adjust the upper dress of spiral shell
There is dish-shaped shrapnel；Outer positioning sleeve is equipped with by bolt above base, outer positioning sleeve is in step cylindrical shape, in outer positioning sleeve cylinder
Hypomere be set with interior positioning sleeve, the centre of interior positioning sleeve is provided with through hole, in the through hole equipped with jacking block and among base
Tapped through hole coaxial line, outer positioning sleeve and interior positioning sleeve are connected with base respectively by bolt；The epimere installation of outer positioning sleeve
There is locator.
Further, periphery is provided with chimb above the jacking block, and the internal diameter of chimb is slightly larger than the shaft end diameter of jackshaft.
Further, described locator one end is fixed with steel ball.
When five shelves gears are press-fit into place, rear bearing inner race does not stress the utility model, and third gear is under frock effect
It is press-fit into place.Whole press fitting process is fast and convenient, and press fitting is efficient, will not damage bearing inner race, press-fit effect is good.Solves original
Having needs to overturn jackshaft during being pressed and switches positioning sleeve, causes part to collide with, so as to influence gearbox assembling quality
Problem.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the partial sectional view of jacking block 6 in the utility model.
In figure：1- bases, 2- adjustment spiral shells, 3- dish shrapnels, positioning sleeve in 4-, the outer positioning sleeves of 5-, 6- jacking blocks, 601- are convex
Side, 7- bolts, 8- locators；Five shelves gears of 100-, 200- jackshafts, 300- bearing inner races.
Embodiment
In conjunction with attached drawing, the invention will be further described：As shown in Figure 1：A kind of quick press mounting gearbox jackshaft part
Device, including base 1, it is characterised in that the centre of base 1 is provided with tapped through hole, and adjustment is provided with tapped through hole
Spiral shell 2, the upper of adjustment spiral shell 2 are equipped with dish-shaped shrapnel 3；Outer positioning sleeve 5 is equipped with by bolt above base 1, outer positioning sleeve 5 is in platform
Rank cylindrical shape, the hypomere in outer 5 cylinder of positioning sleeve are set with interior positioning sleeve 4, and the centre of interior positioning sleeve 4 is provided with through hole, this is logical
In hole equipped with jacking block 6 and with the tapped through hole coaxial line among base 1, outer positioning sleeve 5 and interior positioning sleeve 4 are divided by bolt 7
It is not connected with base 1；The epimere of outer positioning sleeve 5 is provided with locator 8.The jacking block 6 is provided with chimb, and chimb in periphery above
Internal diameter be slightly larger than jackshaft 200 shaft end diameter.Described 8 one end of locator is fixed with steel ball.
Embodiment：The device of the quick press mounting gearbox jackshaft part of the utility model, interior positioning sleeve 4 and outer positioning sleeve
5 are fixed by bolt 7 and base 1, by combining pre-determined bit jackshaft 100 and bearing inner race 300.8 one end of locator
In steel ball insertion 200 teeth groove of jackshaft, fix jackshaft 200.It is movable to adjust the stroke of spiral shell 2 and jacking block 6, can be pushed up
The upper-lower position of block 6.After the completion of debugging, it is ensured that rear bearing inner race 300 is press-fit into place.During press fitting, first by rear bearing
Circle 300 is put into interior 4 hole of positioning sleeve, and five shelves gears 100 are put on interior 4 stepped hole of positioning sleeve and position；Jackshaft 200 is put into outer fixed
Position set 5 is positioned, then third gear is put on jackshaft 200, is pressed with press.Bearing inner race 300 is in dish-shaped shrapnel 3
Under reaction force, it is press-fit into place；
The utility model device is after five shelves gears 100 are press-fit into place, and bearing inner race 300 does not stress, and third gear is in work
Pretend to be press-fit into place under.Whole press fitting process is fast and convenient, and press fitting is efficient, will not damage bearing inner race, press-fit effect is good.
Solving needs during original press fitting to overturn jackshaft and switches positioning sleeve, causes part to collide with, so as to influence speed change box installed
The problem of with quality.
