Description
Technical Field
The utility model belongs to the piston field, concretely relates to internal-combustion engine piston skirt portion processing positioner.
Background
The perpendicularity of a piston pin hole refers to a position error between the axis of the pin hole of the piston of the internal combustion engine and the axis of an outer circle, belongs to the critical indexes of the piston of the internal combustion engine, and poor perpendicularity control can cause poor sealing and eccentric wear of a piston ring, so that engine oil is burned, the oil consumption is increased, and the emission is seriously overproof.
In the prior internal combustion engine piston industry, the outer circle of the skirt of the piston is processed by adopting the positioning of the inner circle of the spigot, the rotation is transmitted by the contact of a shifting block and an inner opening, and the opening of the piston is not absolutely symmetrical, so that the shifting block and the inner opening single-side thrust force make the piston deflect to one side, and the processed pin hole is not vertical to the axis of the outer diameter of the skirt.
SUMMERY OF THE UTILITY MODEL
In order to solve one or more above-mentioned defects among the prior art, the utility model aims to solve the technical problem that an internal-combustion engine skirt portion processing positioner is provided, this skirt portion location processingequipment simple structure can be quick fix a position the piston, is convenient for process skirt portion.
In order to realize the above-mentioned purpose, the utility model provides an internal-combustion engine piston skirt portion processing positioner, the mounting disc comprises an installation plate, the mounting disc middle part is fixed with a tang seat, the edge of tang seat has an ascending flange, is fixed with a locating piece at the middle part of tang seat, the front side and the rear side of locating piece all be provided with swing joint has first shifting block and second shifting block in the locating piece, and in the time of positioning piston, first shifting block and second shifting block can stretch out and draw back along with the interior face of opening of piston.
Furthermore, a sliding hole is formed in the positioning block, a sliding rod is connected in the sliding hole in a sliding mode, and a first shifting block and a second shifting block are fixed at two ends of the sliding rod respectively.
Furthermore, a return spring is connected between the first shifting block and the sliding rod and between the second shifting block and the sliding rod.
Furthermore, the number of the sliding holes in the positioning block is two, and the number of the sliding rods is also two.
The utility model has the advantages that:
firstly, the piston skirt positioning and processing device is simple in structure, capable of quickly positioning a piston and convenient for processing the piston skirt;
secondly, as the positioning block is provided with the sliding hole, and the two ends of the sliding rod in the sliding hole are respectively fixed with the first shifting block and the second shifting block, when the piston is positioned, the first shifting block and the second shifting block can be adapted along with the symmetry degree of the inner open gear of the piston, so that the processing effect of the skirt part of the piston is ensured;
thirdly, because the two sides of the sliding rod are both connected with the return springs, after the piston is taken out of the positioning block, the first shifting block and the second shifting block can return to the initial positions.
Drawings
FIG. 1 is a schematic structural view of the present invention when positioning a piston;
fig. 2 is a schematic structural diagram of the present invention;
fig. 3 is a sectional view of the positioning block of the present invention.
In the figure: 1. mounting a disc; 2. a spigot seat; 3. a flange; 4. positioning blocks; 5. a first shifting block; 6. a second shifting block; 7. a slide hole; 8. a slide bar; 9. a return spring; 10. piston skirt
Detailed Description
The invention will be further explained with reference to the following figures and examples:
referring to fig. 1 to 3, the machining and positioning device for the piston skirt 10 of the internal combustion engine comprises an installation plate 1, wherein a spigot base 2 is fixed in the middle of the installation plate 1, an upward flange 3 is arranged at the edge of the spigot base 2, a positioning block 4 is fixed in the middle of the spigot base 2, a first shifting block 5 and a second shifting block 6 are respectively arranged on the front side and the rear side of the positioning block 4 and movably connected with the positioning block 4, and when the piston is positioned, the first shifting block 5 and the second shifting block 6 can stretch along with an inward opening gear surface of the piston.
The utility model discloses when using the process as follows, earlier on the piston passes through skirt section's inner wall fixed connection to spigot seat 2, when connecting the piston, press the piston downwards, the piston is when moving downwards, its grade face will contact with first shifting block 5 and second shifting block 6 gradually, at this moment, if the interior grade face asymmetry of piston, the shifting block of making the location produces a motion, open the asymmetry in the compensation piston, make the shifting block offset mutually to the thrust of opening two sides in the piston when processing the skirt section excircle, thereby guarantee that the skirt section ellipse is to the straightness accord with the requirement of hanging down of pinhole axis.
Furthermore, a sliding hole 7 is formed in the positioning block 4, a sliding rod 8 is connected to the sliding hole 7 in a sliding manner, and a first shifting block 5 and a second shifting block 6 are fixed at two ends of the sliding rod 8 respectively. As the positioning block 4 is provided with the sliding hole 7, the first shifting block 5 and the second shifting block 6 can be linked, and when one shifting block contracts, the other shifting block extends out.
Furthermore, a return spring 9 is connected between the first shifting block 5 and the sliding rod 8 and between the second shifting block 6 and the sliding rod 8. Since the return springs 9 are connected between the first block 5 and the sliding rod 8 and between the second block 6 and the sliding rod 8, the first block 5 and the second block 6 can return to the initial positions after the piston is taken out of the positioning block 4.
Furthermore, the number of the sliding holes 7 in the positioning block 4 is two, and the number of the sliding rods 8 is also two. Through sliding connection have two slide bars 8 in locating piece 4, so the shifting block is when being extrudeed, and the motion is more stable, and through two slide bars 8 dispersion atress for slide bar 8's life is longer.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
