Description
Technical field
This utility model relates to component of machine mounting technology field, a kind of for making by oneself that bearing outer ring press-fits
Heart assembly tool.
Background technology
Upper centering pressure head is mainly used to be press fit in bearing block bearing outer ring.Press-fit approach in the past is first by outside bearing
Circle is placed on bearing block, is pressed in bearing block by bearing outer ring with the seaming chuck of the band conical surface, centering bearing during press-fiting
Outer ring and the center of bearing block, need when press-fiting artificial twice to take bearing outer ring to carry out assembling work, it is impossible to ensure to press-fit precision, from
And cause and press-fit the defect such as trimming and defective work piece because of what bearing outer ring deflection caused.
Summary of the invention
For overcoming the deficiency of existing mounting technology, goal of the invention of the present utility model is to provide in one pressure head of feeling relieved,
Ask owing to can not disposably be accurately positioned press-fit trimming and the workpiece damage etc. caused during press-fiting solving bearing outer ring
Topic.
For achieving the above object, with for the end face of locating shaft bearing outer-ring and cone on seaming chuck of the present utility model
Face；Three claws are fixed on seaming chuck by straight pin two and holding screw two, and claw can rotate around straight pin two；On claw
Have kidney slot, by holding screw one by spacing for straight pin one in kidney slot；In three endoporus of seaming chuck horizontal direction
Being respectively provided with holding screw three, jacking block is arranged on the hole of the little head end of holding screw three, the spring top end at jacking block and claw
Between Di Bu；Seaming chuck coordinates with pressure head handle.
Described end face is parallel with the upper plane of seaming chuck, in the lower section of upper plane；The conical surface is positioned at the bottom of seaming chuck.
The center of three endoporus of described seaming chuck horizontal direction is perpendicular with the centrage of seaming chuck respectively；The hole of claw
Concentric with the endoporus of seaming chuck horizontal direction.
Described pressure head handle is coaxial with the conical surface.
This utility model compared with prior art, simple in construction, easy to use, with centering and clamping function, seaming chuck
Bearing outer ring can be accurately positioned by end face and the conical surface, it is ensured that bearing outer ring is coaxial with inner hole of bearing seat, and three claws are at bullet simultaneously
Clamp shaft bearing outer-ring under the effect of spring force, it is ensured that location is reliable, and avoid bearing outer ring and come off, liberate operative employee's
Both hands, solve coarse problem that positions when bearing outer ring press-fits, it is ensured that be not required to artificial twice when press-fiting and take bearing outer ring to enter
Row assembling work, can ensure that simultaneously and press-fits precision, eliminates and press-fits trimming and defective work piece etc. because of what bearing outer ring deflection caused
Problem.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3, Figure 4, with for locating shaft bearing outer-ring 13 on seaming chuck 12 of the present utility model
End face 1 and the conical surface 6, bearing outer ring 13 and bearing block 14 central coaxial, end face 1 and the upper plane of seaming chuck 12 during to ensure to press-fit
Parallel, in the lower section of upper plane, the conical surface 6 is positioned at the bottom of seaming chuck 12；Three claws 5 are by straight pin 29, holding screw two
10 are fixed on seaming chuck 12, and claw 5 can rotate around straight pin 9, and claw 5 has kidney slot, will by holding screw 1
Straight pin 1 is spacing in kidney slot, and three claws 5 are idle time, under the effect of spring 4, and outside spreading, it is in
Extreme position；Being respectively provided with holding screw 32 in three endoporus of seaming chuck 12 horizontal direction, jacking block 3 is arranged on holding screw
The little head end of 32, between spring 4 withstands on bottom the end of jacking block 3 and the hole of claw 5；In three of seaming chuck 12 horizontal direction
The center in hole is perpendicular with the centrage of seaming chuck 12 respectively, and the hole of claw 5 is concentric with the endoporus of seaming chuck 12 horizontal direction；On
Pressure head 12 coordinates with pressure head handle 11, and pressure head handle 11 is coaxial with the conical surface 6.
During press-fiting, first overlapping bearing outer ring 13 on seaming chuck 12, under the effect of external force, claw 5 is received inwardly；When
After bearing outer ring 13 is worked good with seaming chuck 12 end face 1 and the conical surface 6, external force is cancelled, and claw 5 has one under the effect of spring 4
Power, holds bearing outer ring 13, it is ensured that bearing outer ring 13 does not falls off, and location is reliable, and three claws 5 block bearing outer ring 13, protect
Card bearing outer ring 13 is fixed on seaming chuck 12, is not required to artificial twice and takes bearing outer ring 13 to carry out assembling work when press-fiting, can
To ensure to press-fit precision, eliminate and press-fit the problem such as trimming and defective work piece because of what bearing outer ring 13 deflection caused；Then pressure head handle
Bearing outer ring 13 is pressed in the bearing block 14 located by 11 by seaming chuck 12, and upper centering pressure head exits, and press-fits complete.
