Description
Technical field
The utility model belongs to internal combustion engine cast iron class cylinder sleeve process technology, mainly proposes a kind of cylinder sleeve undercut groove rolling device.
Background technology
The cylinder sleeve part overwhelming majority adopts cast iron class material to make in the internal combustion engine, and the supporting shoulder arranged all on its structure, its lower surface and cylindrical all have the perpendicularity requirement, mating surface for fear of when assembling and body interferes (the cylinder suit is the end of less than) and drainage occurs, so all designed undercut groove in this junction, position.Because cylinder sleeve brace table shoulder position is in the top of combustion chamber position, it is bearing huge blast pressure and impulsive force, the footpath, the end of while undercut groove and thick other positions that also are less than of arm between the aperture, so its intensity will be hanged down.Prior art all adopts a turning to be shaped to the processing of undercut groove.And the intensity of cast iron materials, toughness is corresponding lower than steel material, adds that certain internal stress is left at the undercut groove position in press-fiting process, therefore works as cylinder sleeve in working order down, and this position often is easy to generate crackle, causes entire machine not run well.And in press-fiting process, all adopt interference fit between the external diameter of cylinder sleeve and the body, therefore the undercut groove position is cracked or directly fracture.
In the diesel engine of introducing, some cylinder sleeve part has proposed to carry out finish rolling hardening to the undercut groove behind the car and has handled, and marked deflection after roll extrusion power, rolling speed, roll extrusion length and the roll extrusion, but do not provide the correlation technique data, in the internal combustion engine of domestic design voluntarily, the equal failed call of countercylinder cover undercut groove carries out finish rolling hardening.Cylinder sleeve is a kind of consumable accessory, and the market supply and demand amount is big, and all original equipment manufacturers all do not carry out the finish rolling hardening processing to undercut groove at present, and therefore cylinder sleeve that forms a complete production network such as direct installation are used and will be brought great hidden danger of quality to machine.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of cylinder sleeve undercut groove rolling device, make this device on request countercylinder cover undercut groove carry out finish rolling hardening and handle, improve the fatigue strength of cylinder sleeve, thereby improve internal combustion engine reliability.
The utility model is finished its invention task by the following technical programs: it mainly is made up of knurling machine, roller and hydraulic mechanism; Adopt existing lathe as knurling machine; Hydraulic mechanism mainly is made up of oil cylinder, oil pump and fuel tank and hydraulic circuit, and oil cylinder is connected by connection seat on the middle carriage of knurling machine, and roller is fixed on the piston rod front end of oil cylinder; Wherein, connection seat and oil cylinder connect firmly one, have centrepin and centrepin bottom in the connection seat and be positioned at the revolution locating hole of middle carriage, with revolution locating hole matched in clearance, constitute oil cylinder relatively turnable structure on middle carriage, on connection seat and middle carriage, have locating slot, hole, oil cylinder is located on middle carriage and pass through bolting.
In the utility model device, with needed rolling pressure, oil cylinder, piston diameter through configuration convert, determine the required pressure that enters oil cylinder, enter in-oil cylinder pressure and then can realize, and from Pressure gauge, directly can read the pressure of being regulated by the overflow valve of regulator solution hydraulic circuit.The oil cylinder that is arranged on the lathe middle carriage is can be rotating, so different cylinder sleeves can be adjusted different roll extrusion angles, and relay control roll extrusion time set-up time on Machine Tool Circuit.After hydraulic oil enters oil cylinder with certain pressure, promote piston and piston rod, finish finish rolling hardening by the roller that is fixed on the piston rod front end and handle.
The apparatus structure that the utility model proposes is advantages of simple comparatively, adopt knurling machine, hydraulic mechanism and the assembly of roller rational structure in the device, make the deflection after roll extrusion power, roll extrusion angle, speed, roll extrusion time and the roll extrusion in the finish rolling hardening process all accomplish controlled; Can reach every specification requirement of undercut groove finish rolling hardening.Handle through finish rolling hardening, all do not find crackle after cylinder sleeve installation and the service test.

The specific embodiment
In conjunction with the accompanying drawings the utility model embodiment is illustrated:
As Fig. 1 and in conjunction with shown in Figure 3, the utility model device mainly is made up of knurling machine 1, roller 4 and hydraulic mechanism 7; Knurling machine adopts existing engine lathe, adopts lathe C630 as knurling machine among this embodiment.Hydraulic mechanism mainly is made of oil cylinder 5, oil pump 19 and fuel tank 21 and hydraulic circuit; Wherein, Oil pump electrical machinery connects power supply, electromagnet CT connects the time relay, cylinder sleeve 6 is installed on the lathe by elastic expansion-sleeve formula anchor clamps 3, elastic expansion-sleeve formula anchor clamps are the prior art structure, oil cylinder 5 is installed on the middle carriage of lathe, and roller 4 is fixed on piston rod 8 front ends of oil cylinder, and roller 4 is similarly the prior art structure.
As shown in Figure 2, when pressure oil piston when the oil circuit joint 11 of oil cylinder 5 enters cylinder cavity is moved to the left, promote piston rod 8 and make roller 4 enter duty; , pressure oil moves right the roller state of deactivating when promoting piston rod when the oil circuit joint 9 of oil cylinder enters cylinder cavity.Roller 4 is installed in piston rod 8 front ends, and the roller endoporus is equipped with needle bearing and matches with axle 12, and roller 4 can be around axle 12 rotations, and oil cylinder 5 is connected one with base 13, so that be connected with the lathe middle carriage.
