Family is complained, and the friction that easily increase occurs with installation axle during use is assembled causes installation axle scratch occur and makes it
Method with service life reduction, and current part deburring is mostly that burr surface is polished using dry sanding paper or emery wheel, not only
Waste time and energy, and other positions of part is scraped damage, thus it is extremely not convenient, it is also necessary to expend a large amount of
Time and manpower.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model be to provide a kind of deburring it is convenient and time saving and energy saving,
The interior oilhole for automobile rocker shaft mounting hole of simple operation goes the frock of flash removed.
In order to realize above-mentioned technical purpose, the technical solution of the utility model is：
A kind of interior oilhole for automobile rocker shaft mounting hole goes the frock of flash removed, and it includes base and on base
The boss of cylindrical structure is held, is provided with vertically on the outer circumference surface of boss at least one for striking off interior oilhole end burr
U-shaped groove, described U-shaped groove extend to boss axial direction both ends, and the both sides spacing of U-shaped groove is pacified at least above rocker arm shaft
Fill the interior oilhole diameter in hole.
Further, the quantity of the U-shaped groove is two, and two U-shaped grooves are located at boss outer circumference surface relatively respectively
Both sides.
Further, end face edge of the described boss away from base and the transition of boss circumference are chamfered transition.
Preferably, described chamfering is circular arc chamfering or ramp down angle.
Further, the base is shaped as cylinder or cuboid.
Further, the axial both ends length of the boss is at least the half of rocking arm shaft mounting hole depth.
Further, one end similar in described boss and base is provided with changeover portion and boss can hide along its axial projection
Projection of the lid changeover portion along boss axial direction.
Further, 0.6~0.95 times of a diameter of rocking arm shaft mounting hole internal diameter of the boss.
Using above-mentioned technical scheme, the beneficial effects of the utility model are：By setting column construction on base
Boss, and it is provided with the U-shaped groove for being used for striking off interior oilhole end burr vertically on the outer circumference surface of boss, make operator only
Boss need to be inserted in the mounting hole of rocker arm shaft, make U-shaped groove on boss and interior oilhole face, then by boss outer circumferential side with
The interior oilhole edge of rocking arm shaft mounting hole is close to and rotated, and U-shaped groove is struck off the burr at interior oilhole edge can be simply square
Just the burr of oilhole removes in completion, not only time saving and energy saving, additionally it is possible to the deburring efficiency of oilhole in raising.
Brief description of the drawings
The utility model is further elaborated with reference to the accompanying drawings and detailed description：
Fig. 1 is the structure simplified diagram of the utility model frock；
Fig. 2 is a wherein viewing angle constructions schematic diagram of the utility model frock along boss axial direction；
Fig. 3 is the partial structurtes simplified diagram of rocker arm shaft；
Fig. 4 is view when the utility model frock is implemented, and it illustrates in boss insertion rocking arm shaft mounting hole
Section fit structure signal.
Embodiment
As shown in Fig. 1 to one of 4, the utility model includes base 1 and the boss 2 located at the cylindrical structure in the upper end of base 1,
At least one U-shaped groove 21 for being used to strike off the interior end burr of oilhole 41 is provided with the outer circumference surface of boss 2 vertically, it is described
U-shaped groove 21 extends to the axial direction both ends of boss 2, and the both sides spacing of U-shaped groove 21 is at least above the mounting hole 42 of rocker arm shaft 4
The interior diameter of oilhole 41.
Wherein in order to improve deburring efficiency and be easy to the situation of the more interior oilholes 41 of reply, the quantity of U-shaped groove 21 is two
It is individual, and two U-shaped grooves 21 are respectively with respect to located at the both sides of the outer circumference surface of boss 2.
In addition, in order to avoid producing unfavorable scraping to the side wall of mounting hole 42 when boss 2 inserts mounting hole 42, boss 2 is remote
It is the transition of chamfering 22 from the end face edge of base 1 and the transition of the circumference of boss 2, it is preferred that described chamfering 22 is fallen for circular arc
Angle or ramp down angle.
In order to adapt to different operating environments, the shape of base 2 can be cylinder or cuboid.
In addition, the axial both ends length of the boss 2 is at least the half of the depth of 4 mounting hole of rocker arm shaft 42.
Can smoothly come off and will not be accumulated in U-shaped groove 21 for the ease of the burr under striking off, described boss 2 with
One end similar in base 1 is provided with changeover portion 3 and boss 2 can cover changeover portion 3 along the axial direction of boss 2 along its axial projection
Projection.
0.6~0.95 times of the internal diameter of 4 mounting hole of a diameter of rocker arm shaft 42 of boss 2.
The utility model uses above-mentioned technical scheme, by setting the boss 2 of column construction on base 1, and convex
