Description
Technical field
The utility model belongs to part of automobile engine technical field, relates to steel pistons noncircular pin hole special processing equipment.
Background technology
For meeting motor vehicle emission state IV, state V and above standard, realize target for energy-saving and emission-reduction, high-power engine is towards high detonation pressure, the development of high power per literization, engine design is continually strengthened, cylinder temperature and the pressure of engine constantly rise, the thermic load that piston bears and mechanical load will be more and more higher, and all-aluminium piston cannot meet instructions for use, increasing employing steel top and aluminum skirt formula radial type piston and all-steel piston.Steel pistons is in use coordinated with piston pin by piston pin hole, and the power of engine is spread out of on connecting rod and bent axle by piston pin, and detonation pressure is higher, stressed larger.Distortion can be produced because piston pin is stressed, so just carried out deformation process to piston pin hole in the design phase, become noncircular pin hole (conical surface pin-and-hole, oval pinhole etc.), to adapt to the distortion of piston pin, prevent the inefficacy of piston and piston pin in Long-Time Service process.Traditional aluminium piston pin-and-hole process equipment cutting force is little, can not meet steel pistons noncircular pin hole processing request.The processing of steel pistons noncircular pin hole is the important topic instantly faced.
Summary of the invention
For meeting the processing of steel pistons noncircular pin hole, ensureing the crudy of steel pistons noncircular pin hole, the utility model proposes steel pistons noncircular pin hole special processing equipment.
The technical scheme that the utility model adopts is: steel pistons noncircular pin hole special processing equipment, comprise frame, electric-control system, it is characterized in that: be separately installed with an electronic boring and milling unit head in the both sides of frame, two electronic boring and milling unit heads are oppositely arranged and keep coaxial, and the centre of frame is provided with electronic pair of coordinate cross slid platform; The main shaft of electronic boring and milling unit head is liquid suspension radial deflection main shaft; The side of frame is equipped with Hydraulic Station, Hydraulic Station and liquid suspension radial deflection main shaft supporting;
Hydraulic Station, electronic boring and milling unit head and electronic pair of coordinate cross slid platform are by electric control system controls;
Add man-hour, steel pistons is placed on electronic pair of coordinate cross slid platform, and steel pistons is separately mobile to two liquid suspension radial deflection main shafts, twice pin hole processing; In pin-and-hole process, along with the movement of steel pistons, liquid suspension radial deflection main shaft diameter, to the side-play amount being displaced to regulation, realizes steel pistons pin-and-hole bus and reaches arbitrary curve.
The beneficial effects of the utility model are: adopt liquid suspension radial deflection main shaft, in load 2000N, in spindle shaft 4500rpm, precisely control smallest offset 0.001mm, can reach 0.0005mm in skew 0.25mm internal linear precision; Have employed two electronic boring and milling power (two main shafts), pin-and-hole realizes twice processing, and realizing final allowance can precisely control, and can realize allowance 0.03mm-0.1mm, realizes the stability of steel pistons noncircular pin hole processing, ensures product quality.
Accompanying drawing explanation
Fig. 1 is steel pistons noncircular pin hole special processing equipment structural representation;
Fig. 2 is the schematic diagram of liquid suspension radial deflection main shaft.
Detailed description of the invention
As shown in Figure 1, steel pistons noncircular pin hole special processing equipment, comprise frame 3, electric-control system 2, Hydraulic Station 6, an electronic boring and milling unit head 1 is separately installed with in the both sides of frame 3, two electronic boring and milling unit heads 1 are oppositely arranged and keep coaxial, and the centre of frame is provided with electronic pair of coordinate cross slid platform 4; The main shaft of electronic boring and milling unit head 1 is liquid suspension radial deflection main shaft 8, and Hydraulic Station 6 is supporting with liquid suspension radial deflection main shaft 8; Hydraulic Station 6, electronic boring and milling unit head 1 and electronic pair of coordinate cross slid platform 4 are controlled by electric-control system 2.
As shown in Figure 2, have a confined space 8, be full of hydraulic oil in confined space 8 at liquid suspension radial deflection main shaft 7 head, the pressure that the pressure by controlling hydraulic oil in main shaft produces makes spindle nose offset to a fixed-direction.
Composition graphs 1 describes operation principle of the present utility model: add man-hour, and steel pistons 5 is placed on electronic pair of coordinate cross slid platform 4, and steel pistons 5 is separately mobile to two liquid suspension radial deflection main shafts 7, twice pin hole processing; In pin-and-hole process, along with the movement of steel pistons 5, liquid suspension radial deflection main shaft 7 radial deflection, to the side-play amount of regulation, realizes steel pistons pin-and-hole bus and reaches arbitrary curve.Add and set steel pistons shift position man-hour and offset corresponding numerical value with main shaft, namely realize the processing of noncircular pin hole, all control overflow send instruction by electric-control system 2.
