The fixation device of secured adjusted part, the positioning end from top to bottom successively include two the first positioning surfaces being disposed in parallel relation to one another,
The second positioning surface formed by shaft shoulder outer circumference surface, the diameter of the shaft shoulder are gradually reduced the outer circumference surface for making the shaft shoulder from top to bottom
Upper formation tilt angle, the shaft shoulder is set on the base on end face and the diameter of shaft shoulder lower end is less than the straight of pedestal upper surface
Diameter, the part that the shaft shoulder is protruded in pedestal upper surface form third positioning surface, and first positioning surface is positioned for piston internal retaining surface, institute
It states the second positioning surface to position for piston cavity diameter, the third positioning surface is positioned for piston skirt.
The mounting hole is the blind hole down-set from pedestal upper surface, and connecting shaft is connect with blind hole clearance fit.
The bottom centre of the blind hole is equipped with positioning pin, and the lower end surface central part of connecting shaft is correspondingly provided with location hole, connects
The center of the two is aligned by positioning pin after axis insertion blind hole.
The fixed device includes a fixing bolt, and the side of blind hole is equipped with fixing bolt and places hole on the pedestal, Gu
Determine bolt and place hole to be against its tail end in connecting shaft.
The utility model uses above technical scheme, and it is sliding that existing piston crown processing localization tool is changed to two jigs
It is installed with (clearance fit), tooling can be adjusted directly without dismounting.Screw is fixed after adjustment, is allowed to easy to adjust simple, fixed
Position is more steady, and a jig can match the blank of different pattern number batches, improves machining accuracy and production efficiency.
Detailed description of the invention
The utility model is described in further details below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural schematic diagram that existing piston crown processes localization tool；
Fig. 2 is the structural schematic diagram that a kind of adjusting flexible plug head of the utility model processes localization tool；
Fig. 3 is the structural schematic diagram of pedestal；
Fig. 4 is the structural schematic diagram of regulating part.
Specific embodiment
As shown in one of attached drawing 2-4, the utility model includes pedestal 1 and the regulating part 2 that is arranged on pedestal 1, the tune
The positioning end that part 2 includes the connecting pin connecting with pedestal 1 and connect with piston is saved, the connecting pin includes a connecting shaft 21, bottom
The end face of seat 1 is equipped with a mounting hole 11, and connecting shaft 21 is inserted into mounting hole 11 and is connect with 11 clearance fit of mounting hole, the pedestal
1 is equipped with the fixation device 3 for secured adjusted part 2, and the positioning end successively includes two from top to bottom and is disposed in parallel relation to one another
The first positioning surface 5, the second positioning surface 6 for being formed by shaft shoulder outer circumference surface, the diameter of the shaft shoulder is gradually reduced from top to bottom
Make to form tilt angle on the outer circumference surface of the shaft shoulder, the shaft shoulder is arranged on 1 upper surface of pedestal and the diameter of shaft shoulder lower end
Less than the diameter of 1 upper surface of pedestal, the part that the shaft shoulder is protruded in 1 upper surface of pedestal forms third positioning surface 7, first positioning surface
5 position for piston internal retaining surface, and second positioning surface 6 is positioned for piston cavity diameter, and the third positioning surface 7 is for living
Fill in skirt section positioning.
Further, the mounting hole 11 is the blind hole down-set from 1 upper surface of pedestal, connecting shaft 21 and blind hole gap
It is cooperatively connected.
Further, the bottom centre of the blind hole is equipped with positioning pin 4, and the lower end surface central part of connecting shaft 21 is correspondingly provided with
Location hole, connecting shaft 21, which is inserted into after blind hole, is aligned the center of the two by positioning pin 4.
Further, the fixed device 3 includes a fixing bolt, and the side of blind hole is equipped with fixed spiral shell on the pedestal 1
Bolt places hole 12, and fixing bolt, which places hole 12, is against its tail end in connecting shaft 21.
In the utility model, pedestal 1 and regulating part 2 use 24 hole axle slide fit (clearance fit) of φ, because of piston blank inner cavity
Diameter has drafting angle, therefore the position location of the second positioning surface 6 is more up, and piston blank intracavity diameter is smaller, and positioning is tighter, leads to
Cross the height of adjustment regulating part 2, in place when with fixing bolt solid lock fixed height, the positioning to different blanks can be realized,
Existing piston crown processing localization tool is changed to two jig slide fit (clearance fit) installations by the utility model, and tooling is not necessarily to
Dismounting can be adjusted directly.Screw is fixed after adjustment, is allowed to easy to adjust simple, positioning is more steady, and a jig can match not
With the blank of pattern number batch, machining accuracy and production efficiency are improved.
