When guide rod 9 and pedestal 1 between constitute for fixed piston 4 mounting base 10, what thus piston 4 can be stablized is placed on pedestal 1
Without movement, stability when installation retaining ring for piston pin 2 is further improved.
As shown in figure 4, in order to improve stability when guide rod 9 is vertically arranged, level opens up that there are two grafting on pedestal 1
Hole 11, and above-mentioned two spliced eye 11 is parallel opens up.Equal horizontal sliding is connected with an inserted link 12 in each spliced eye 11.Separately
Outside, several trepannings 13 for 9 grafting of above-mentioned guide rod, wherein trepanning 13 and above-mentioned grafting are offered in the upper surface of spliced eye 11
Hole 11 is interconnected, while opening up in the lower end of guide rod 9 that there are one the through-hole 14 for above-mentioned 12 grafting of inserted link, through-hole 14 and grafting
The center line in hole 11 is located along the same line.Thus inserted link 12 can will sequentially pass through spliced eye 11 and through-hole 14, and by guide rod 9
Fixation is locked on pedestal 1, further improves stability when guide rod 9 is vertically arranged.
As shown in figure 4, inserted link 12 is inserted into spliced eye 11 or takes out positioned at spliced eye 11 simultaneously by worker for convenience
Interior inserted link 12, is equipped with connecting rod 15 between adjacent two inserted links 12, and above-mentioned connecting rod 15 is located at above-mentioned inserted link 12 bottom of far from
The side of seat 1.Thus worker only need to pull or push connecting rod 15 locking guide rod 9 to can be achieved at the same time or by guide rod 9 from pedestal 1
Place takes out, very convenient.As shown in figure 4, worker takes out the inserted link 12 being plugged in spliced eye 11 for convenience, in connecting rod 15
Plane of the center where it be outwardly formed smooth excessiveness arch upward 16.Thus worker above-mentioned arches upward 16 by holding
Inserted link 12 can will be taken out, facilitate worker while taking out the inserted link 12 being plugged in spliced eye 11.
Due to smaller in 3 bottom diameter of casing, at this time after the quantity of 3 inner carrier pin baffle ring 2 of casing is reduced, piston pin gear
Circle 2 can be moved up along guide surface 7 automatically under elastic reaction, to be restored to the nature of retaining ring for piston pin 2, if worker at this time
When mounted, it cannot understand to recognize the particular number of 3 inner carrier pin baffle ring 2 of casing, it is cumbersome, therefore for convenience
The quantity of actual piston pin baffle ring 2 in casing 3 is solved, as shown in Figure 4 and Figure 5, is opened on the outer wall of casing 3 and is equipped with strip vertically
Slip hole 17, the end of wherein compression bar 6 is equipped with an abutting bar 18 perpendicular with compression bar 6, the one of above-mentioned abutting bar 18
End is welded on compression bar 6 on the circumferential side wall of lower end, and the other end passes through above-mentioned slip hole 17 and protrudes outside casing 3.By
For this worker when installing retaining ring for piston pin 2, the position that bar 18 is abutted when according to pressing can determine whether remaining piston pin gear in casing 3
The number of circle 2, it is very convenient.
As shown in Figure 4 and Figure 5, in order to further appreciate that the quantity of remaining retaining ring for piston pin 2, in the inner wall of slip hole 17
Upper to be spaced apart equipped with several card slots 19 for being clamped the strip for abutting bar 18, the upper surface level of wherein 19 inner wall of card slot is set
It sets, and card slot 19 is opened up along the circumferential direction of casing 3.Thus worker presses moulded rod 6, and compression bar 6 pushes retaining ring for piston pin 2 to move down simultaneously
So that a lowermost retaining ring for piston pin 2 is connected in mounting groove 5, while rotating horizontally compression bar 6 so that abut bar 18 along set
The axial direction of pipe 3 is mobile and is entered in corresponding card slot 19 from slip hole 17, abuts bar 18 at this time in casing 3
Under the action of retaining ring for piston pin 2, the thrust of compression bar 6 one straight up is given so that abutting bar 18 can be stablized is connected to
At the upper end inner wall of card slot 19, the locking to abutting bar 18 thus can be realized, while can also be clearly understood that in casing 3
The volume residual of retaining ring for piston pin 2, it is very convenient.
In order to facilitate the quantity of remaining retaining ring for piston pin 2 is understood, so that the spacing between two neighboring card slot 19 is equal to and live
The height of plug pin baffle ring 2.Thus operator need to will only abut bar 18 and is moved in next card slot 19 out of upper a card slot 19,
The lowermost retaining ring for piston pin 2 in casing 3 can be snapped fit onto in mounting groove 5 at this time, it is not only easy to operate, but also can also understand
The volume residual for recognizing 3 inner carrier pin baffle ring 2 of casing.As shown in figure 4, worker installs for convenience, in the upper end of compression bar 6
Equipped with pressing plate 20 so that worker is not easy to be damaged to palm in Manual press compression bar 6 so that worker is more safe when using.
Operation principle：
When work, retaining ring for piston pin 2 is lowered into from the upper end edge guide surface 7 of casing 3 into casing 3 by worker successively；
Then piston 4, the pin of piston 4 and the components such as connecting rod after combination are assembled and is placed on pedestal 1；It then will be under casing 3
End is connected at 5 notch of mounting groove of piston 4, while the lower end of guide rod 9 being plugged on pedestal 1, at this time in every guide rod 9
Center portion position is inconsistent with the circumferential side wall of piston 4, then holds connecting rod 15 so that 12 level of inserted link is plugged on corresponding insert
It connects in hole 11 and through-hole 14, you can locking guide rod 9.Then worker presses moulded rod 6, and compression bar 6 pushes retaining ring for piston pin 2 to move down, together
When a lowermost retaining ring for piston pin 2 can also be made to move down and be connected in mounting groove 5 thus.Rotate horizontally compression bar simultaneously
6 so that abut bar 18 and move along the axial direction of casing 3 and entered in corresponding card slot 19 from slip hole 17, support at this time
Extension bar 18 can give the thrust of compression bar 6 one straight up under the action of retaining ring for piston pin 2 so that abutting bar 18 can
Stable is connected at the upper end inner wall of card slot 19, the locking to abutting bar 18 thus can be realized, worker can be clear
Recognize the number of remaining retaining ring for piston pin 2 in casing 3.
Specific embodiment is only the explanation to the utility model, is not limitations of the present invention, this field
Technical staff can as needed make the present embodiment the modification of not creative contribution after reading this specification, but only
It all to be protected by Patent Law in the right of the utility model.
