As shown in fig. 7, Fig. 7, which is assembly tool that bowl-type according to the present utility model blocks, operates with schematic diagram.
In some embodiments, the application method of 7 assembly tool is blocked according to a kind of bowl-type of specific embodiment of the present invention,
It is used for the oblique oil duct 61 for blocking cylinder block 6, and 61 periphery of oblique oil duct of cylinder block 6 has threaded hole 63, and application method uses upper
The assembly tool stated, the application method include the following steps：
Step 1：Bowl-type first is blocked 7 pines to be sleeved on punch 13, under the suction of magnet 14, bowl-type blocks 7 and inhaled
It is attached on punch 13, will not fall down；
Step 2：Then, the plane assembly tool of this set bowl-type blocking 7 being placed on where the oblique oil duct 61 of cylinder block 6
On, using at least two threaded holes 63 in the plane where the oblique oil duct 61 of at least two bolts 5 alignment cylinder block 6, and twist
Tight at least two bolt 5, bowl-type blocking at this time 7 have been substantially aligned with the oblique oil duct 61 of cylinder block 6, and require the following table of pressing plate 2
There are minim gaps between face and the upper surface of positioning seat 3, i.e. positioning seat 3 is not compressed completely by pressing plate 2, because of stop collar small end
Between 42 outer diameter and the small end inner diameter in positioning seat straight step hole 32 and the outer diameter of stop collar big end 43 and positioning seat straight step
Coordinated between the big end internal diameter in hole 32 using wide arc gap, therefore can in the horizontal direction freely between positioning seat 3 and pressing plate 2
Mobile small distance；
Step 3：Then, the upper surface of bar tail 11 is beaten using tool, bowl-type is blocked 7 toward the oblique of cylinder block 6 by punch 13
It promotes in oil duct 61, at this time if bowl-type blocks the center of 7 center and the oblique oil duct 61 of cylinder block 6 not completely to just, still
It is oblique in oral area there are a small amount of deviations, but when the oral area oblique angle 62 of oblique oil duct 61 that cylinder block 6 is encountered on the head of bowl-type blocking 7
Under the guiding role at angle 62, positioning seat 3, push-rod assembly 1 and bowl-type, which block 7, will integrally make the adjustment movement of horizontal direction, into
One step calibration bowl-type blocks 7 position, and bowl-type is made to block the center of the oblique oil duct 61 of 7 center automatic alignment cylinder block 6；
Step 4：When bowl-type blocks the center of the oblique oil duct 61 of 7 center and cylinder block 6 completely to after just, using tool
Continue to beat the upper surface of bar tail 11, bowl-type blocks 7 and will be pressed into inside the oblique oil duct 61 of cylinder block 6 by punch 13 at this time, works as limit
Position ring 12 is when encountering the bottom surface of 21 big end of pressing plate sloping step hole, and bowl-type blocks 7 no longer toward moving inside the oblique oil duct 61 of cylinder block 6
Dynamic, the assembling process that bowl-type blocks 7 is completed；And
Step 5：Finally, at least two bolts 5 are removed, the assembly tool that a whole set of bowl-type is blocked to 7 unloads, entire to use
Operating process finishes.
In conclusion the assembly tool that the bowl-type of the utility model blocks is compared with prior art, there is structure design letter
Single reasonable, easy for operation, the bowl-type that can effectively improve oil duct blocks installation effectiveness and assembles the excellent of bearing accuracy
Point.Also there is the assembling quality for improving Bowl Plug simultaneously, it is ensured that bowl-type is blocked with good sealing performance and effectively prevent
There is the advantageous effect of oil leak or Bowl Plug release failure in IC engine cylinder block oil duct.
