Description
Technical field
This utility model relates to press-fiting auxiliary device field, is specially a kind of copper bush correcting press-fitting tool.
Background technology
In our daily production process, it is frequently encountered the situation that copper bush need to be pressed in workpiece hole, owing to press-fiting
Copper bush is intended to press-in in the case of interference, and copper bush is softer due to material again, external diameter and interior pore volume in pressing process
Easily contraction distortion, therefore must assure that when press-fiting copper bush that copper bush external diameter is coaxial with inner hole of workpiece, is the most vertically pressed into.This
The copper bush of sample press-in could enter smooth and easy, and contraction distortion is uniform.Common way is to tap copper bush end face the most gently
Edge so that it is slowly entering in workpiece hole, this way is higher to labor claim, and copper bush external diameter is easily pulled, chewed,
The contraction distortion of endoporus is uneven, and assembling quality can not be guaranteed.
Utility model content
This utility model provides a kind of copper bush correcting press-fitting tool, for solving the contraction during copper bush press-fits
Problem on deformation, improves assembling quality.
The technical solution of the utility model is: be included in during press-fiting copper bush the correcting transition playing correcting effect
Head and top lifting pressure transitional function press-loading head, described correcting transition head is multidiameter, including be positioned at two ends first location shaft part,
Second positions shaft part and at the 3rd location shaft part that the first location shaft part and second position between shaft part and lateral surface is the conical surface,
Described press-loading head is multidiameter, including the 4th location shaft part and the 5th location shaft part.
Preferred as such scheme, described first location shaft part external diameter is identical with copper bush internal diameter, and second positions shaft part
The inner hole of workpiece diameter that external diameter is pressed into copper bush is identical, and the maximum gauge of described 3rd location shaft part is more than in copper bush
Footpath, less than the second location shaft part external diameter, minimum diameter is less than the first location shaft section diameter.
Preferred as such scheme, described 4th location shaft section diameter is identical with copper bush internal diameter, and the 5th positions shaft part
Diameter is more than copper bush internal diameter, less than copper bush external diameter.
Preferred as such scheme, described correcting transition head is hollow axle.
The beneficial effects of the utility model are: this copper bush correcting press-fitting tool can make copper bush during press-fiting
Smooth and easy entrance, copper bush external diameter remains coaxially with inner hole of workpiece and vertical is pressed into, and end face not easy damaged, contraction distortion is equal
Even, the excessive head of correcting and press-loading head easily take out, and substantially increase copper bush press-fits quality.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model coordinates with copper bush.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
As it is shown in figure 1, the structure of the present embodiment is included in the correcting transition playing correcting effect during press-fiting copper bush 3
Head and the press-loading head of top lifting pressure transitional function, described correcting transition head is hollow multidiameter, including the first location being positioned at two ends
Shaft part 4, second positions shaft part 6 and between the first location shaft part 4 and the second location shaft part 6 and lateral surface is the 3rd of the conical surface the
Location shaft part 5, described press-loading head is multidiameter, including the 4th locating shaft 2 sections and the 5th location shaft part 1.
In the present embodiment, described first location shaft part 4 external diameter is identical with copper bush 3 internal diameter, the second location shaft part 6 external diameter
Identical with the inner hole of workpiece diameter that copper bush 3 is pressed into, the maximum gauge of described 3rd location shaft part 5 is more than copper bush 3 internal diameter,
Less than the second location shaft part 6 external diameter, minimum diameter is less than the first location shaft part 4 diameter, described 4th location shaft section diameter and copper
Lining 3 internal diameter is identical, and the 5th location shaft section diameter is more than copper bush 3 internal diameter, less than copper bush 3 external diameter.
In said structure, the first location shaft part 4 diameter of the excessive head of correcting is consistent with copper bush 3 endoporus, the second location
Shaft part 6 external diameter is identical with the inner hole of workpiece diameter that copper bush 3 is pressed into, it is ensured that coaxial entrance when press-fiting；Lateral surface is the conical surface
The 3rd location shaft part 5 to the copper bush 3 endoporus effect of playing a supportive role, transition piece when press-loading head is to press-fit, it is to avoid directly push up
Pressing copper bush 3 edge to cause end face to damage, top pressure press-loading head can drive copper bush 3 to enter.
Before press-fiting, first the second location shaft part 6 of correcting transition head is inserted in the workpiece that copper bush 3 is pressed into
Kong Zhong, then copper bush 3 is set in correcting transition head the 3rd location shaft part 5 on, finally press-loading head is loaded on copper bush 3 another
End.Whole press-fit during correcting transition head second location shaft part 6 make moved in coaxial along inner hole of workpiece all the time, with this come
Copper bush 3 is guided to make the most coaxially to enter.When the external diameter of copper bush 3 and endoporus shrink during press-fiting, correcting
The conical surface of the 3rd location shaft part 5 of transition head can be compressed axially and is axially disengaging the movement of copper bush 3, now correcting
The location correcting effect of ferry is complete.Continue top pressure press-loading head and drive copper bush 3 to be coaxially pressed into place.Now
Take out correcting transition head and press-loading head, complete to press-fit work.
