Abstract
The utility model provides a piston steel top finish turning tang location structure, belongs to piston steel top processing frock technical field. This kind of piston steel top tight structure of locating clip includes lathe main shaft, positioning disk and three jack catch, and the positioning disk passes through the connecting bolt installation to be fixed and fix the three jack catch installation of equipartition on the positioning disk on the lathe main shaft again, tang and piston steel top 0.03~0.05mm of excircle fit clearance on the jack catch, the three hook clamp plate of equipartition pass through for the guide post connecting bolt fixed to the positioning disk compression piston steel top, make piston steel top top surface and jack catch terminal surface lean on sternly. This location structure compresses tightly annular positioning piston steel top top surface position with location tang positioning piston steel top circumferencial direction, this simple structure, and dismouting piston steel top is quick, reduces the deformation on piston steel top, and repeated positioning accuracy is high.
Description
Technical field
The utility model is related to a kind of piston steel top smart car seam location structure, belongs to piston steel top processing tool technology neck
Domain.
Background technology
Piston is the core component of engine, and piston steel top is that the main stress that piston bears during explosion pressure in cylinder is joined
Part, can directly affect service life and the security of engine.So will strictly control piston in piston steel top process
The processing dimension on steel top and form and position tolerance.There is problems with traditional piston steel top smart car seam：Workpiece positions plane clamping
After there is gap, workpiece can not with claw positioning plane fit completely；The main shaft of workpiece fragile lathe is tapped when workpiece is installed
Precision, and inconvenient operation；When workpiece clamp clamp force is not enough, workpiece can come off during machine tooling, and safe thing easily occurs
Therefore；When clamping force is excessive, workpiece easily deforms, and workpiece size and form and position tolerance are difficult to ensure that, human factor causes quality to ask
The hidden danger of topic is big.
Content of the invention
In order to overcome problems of the prior art, the utility model provides a kind of piston steel top smart car seam positioning knot
Structure.This location structure positions piston circumferencial direction, compression annular groove positioning piston-top surface position with positioning spigot, and this structure is simple,
Dismounting is quick, reduces the deformation of piston steel top, and repetitive positioning accuracy is high.
The utility model adopt scheme be：A kind of piston steel top smart car seam location structure, it includes machine tool chief axis, it
Also include positioning disk and three claws, described positioning disk is joined with the inner stopper on positioning disk by the male half coupling on machine tool chief axis
Close, with the second connecting bolt, positioning disk is fixed on machine tool chief axis, three leads are provided with positioning disk, by three claws
Installed with the 3rd connecting bolt in groove on insertion positioning disk and be fixed on positioning disk；Piston steel top is placed in three claws
After on claw seam, three leads load onto hook pressing plate respectively, allow the pressing plate head of hook pressing plate be located at piston steel top
In piston ring groove, with the first connecting bolt, hook pressing plate is fastened on lead.
The described claw seam fit clearance cylindrical with piston steel top is 0.03～0.05mm.Three uniform hook pressing plates
Clamping piston steel top on positioning disk is fixed to the first connecting bolt by lead, so that piston steel top top surface is leaned on claw end face
Sternly
The beneficial effects of the utility model are：This piston steel top positioning clamping include machine tool chief axis, positioning disk and
Three claws, positioning disk is fixed on machine tool chief axis to be fixed on three uniform claws by connecting bolt again to be determined
On the disk of position, seam on claw and piston steel top cylindrical fit clearance 0.03～0.05mm, three uniform hook pressing plates pass through
Lead connecting bolt is fixed to clamping piston steel top on positioning disk, so that piston steel top top surface and claw end face is leaned on tight.This is fixed
Bit architecture positions piston steel top circumferencial direction, compression annular groove positioning piston steel top top side location with positioning spigot, and this structure is simple,
Dismounting piston steel top is quick, reduces the deformation of piston steel top, and repetitive positioning accuracy is high.
Brief description

Specific embodiment
Further illustrate structure of the present utility model and using method below in conjunction with the accompanying drawings.
Fig. 1 shows a kind of piston steel top smart car seam location structure sectional view.In figure, this piston steel top smart car seam
Location structure includes machine tool chief axis 1, positioning disk 2 and three claws 3.Positioning disk 2 passes through the male half coupling 1a on machine tool chief axis 1 and determines
Inner stopper 2a cooperation on the disk 2 of position, with the second connecting bolt 7, positioning disk 2 is fixed on machine tool chief axis 1, sets on positioning disk 2
There are three leads 4, three claws 3 are inserted in the groove on positioning disk 2 and be fixed to positioning disk with the 3rd connecting bolt 8 installation
On 2.After piston steel top 9 is placed on the claw seam 3a of three claws 3, three leads 4 load onto hook pressing plate respectively
5, allow the pressing plate head 5a of hook pressing plate 5 to be located in the piston ring groove of piston steel top 9, tight with 6 hook pressing plates 5 of the first connecting bolt
Gu on lead 4.The claw seam 3a fit clearance cylindrical with piston steel top 9 is 0.03～0.05mm.
Using above-mentioned technical scheme, first piston steel top external diameter is installed on claw seam, is passed through with hook pressing plate
Lead connecting bolt is fixed to clamping piston steel top on positioning disk, so that piston steel top top surface and claw end face is leaned on tight, this is fixed
Bit architecture positions piston steel top circumferencial direction, compression annular groove positioning piston steel top top side location with positioning spigot, and this structure is simple,
Dismounting piston steel top is quick, reduces deformation, and repetitive positioning accuracy is high.
