Abstract
A honing technology for the cylinder sleeve of engine is composed of control controller, abrasive feeder, honing head and fixture, and features that the abrasive sheet on honing head is attached to the inner surface of cylinder sleeve and driven by honing head to do reciprocating linear and rotary motions while the abrasive is continuously added to cylinder sleeve and is made up by mixing silicon carbide with abrasive oil.
Description
The present invention relates to a kind of processing technology and plant equipment of cylinder sleeve of engine.
Aspect the civilian goods automobile, the processing of automobile cylinder sleeve at length introduced in the article " processing technology of engine major part and equipment " that publishes of " building-block machine and automation process technology " 1997 the 2nd phases of magazine, article has been done introduction at length to the equipment and the technology of inner surface of cylinder liner processing, brush honing processing mode after in the last fine finishining of cylinder sleeve, taking honing, the inner surface of cylinder liner quality that this kind technology mode obtains is continuous channel and the alternate shape in certain plane by accompanying drawing as can be known, on the one hand, groove is used for store oil, form lubricating oil film during work, the support piston effect is played on the plane on the other hand, gains in strength.Unfavorable aspect is that groove is a continuous type, easily causes stress to concentrate, and is used on the supercharged engine, does not satisfy requirement, and bulk life time reduces.Aspect military products, usually phosphatization is handled after adopting flat top honing, purpose is in order to obtain uniform store oil cave, because the parkerized factor of influence is a lot, is difficult to obtain desirable phosphatization surface, causes when supercharged engine is worked, oil film between piston ring and the cylinder sleeve is imperfect, reduce the life-span of piston ring and cylinder sleeve, after phosphatization was handled in addition, environmental pollution was also very serious.
The objective of the invention is to provide a kind of cylinder sleeve of engine honing technology and equipment that improves the cylinder sleeve of engine inner surface quality.
Solution of the present invention is to adopt the honing lapping head and the grinding agent that have abrasive sheet that inner surface of cylinder liner is carried out fine finishining.Grinding agent adopts carborundum and grinding oil to be mixed and made into, and volume ratio is that 1 part of grinding oil is joined 0.7-1 part carborundum, and the model of carborundum is W20, W28, W40, W28 carborundum best results, and grinding oil can be selected for use No. 20 or No. 10 lathe machine oil.For making the top gem of a girdle-pendant grind better effects if, can in grinding oil, be blended into a small amount of kerosene, the volume ratio of grinding oil and kerosene is 100: 0.1-0.2.Add man-hour, abrasive sheet is fitted on the inboard wall of cylinder liner, drive by honing lapping head and to carry out up and down reciprocatingly rectilinear motion and rotatablely move, simultaneously constantly add grinding agent in cylinder sleeve, the honing lapping head point-to-point speed is a per minute 7-9 rice, and rotary speed is changeed for per minute 50-180, the top gem of a girdle-pendant grinds and up and down reciprocatingly processes number of times is 120-150 time, the quantity delivered of grinding agent is the 600-1200 milliliter, divides 16-22 adding, and it is 0.9-1.4bar that the top gem of a girdle-pendant grinds pressure.
Process equipment of the present invention is by the control executor, the grinding agent feeder, honing lapping head and anchor clamps are formed, wherein honing lapping head is mainly by matrix, abrasive sheet, cone is formed, cone is in matrix, two sealing slide blocks and four transmission pressure sliders are arranged on the matrix, evenly distribute, two sealing slide blocks are corresponding, abrasive sheet is the cylindrical body that two semicircular cylinders are formed, between sealing slide block and the two slice lapping sheet slits sealing strip is arranged, between the inwall of transmission pressure slider and abrasive sheet roller is arranged, cone has male cone (strobilus masculinus) and inner conical surface, transmit pressure slider and seal slide block contact-making surface is arranged, male cone (strobilus masculinus) contacts with contact-making surface, transmit that pressure slider and sealed sliding are packaged a pin, pin contacts with inner conical surface, on the abrasive sheet, following two ends outer wall is with turn respectively, baffle plate is equipped with in the bottom of matrix, between matrix and the abrasive sheet straight pin is arranged, on the outer wall of abrasive sheet cannelure is arranged, there is partition the middle and lower part of cannelure, and the top of matrix connects the connecting rod of control executor, and the top of cone connects the depression bar of control executor, wherein abrasive sheet can adopt No. 45 steel to make, and hardness is HB200-250.Cylinder sleeve is carried out the top gem of a girdle-pendant to be ground and adds man-hour, the clamp cylinder sleeve, the nozzle alignment cylinder sleeve inner chamber of grinding agent feeder, honing lapping head is put into cylinder sleeve, under the control of control executor, connecting rod drives the honing lapping head rotation and moves up and down, depression bar presses down cone, transmission pressure slider in the male cone (strobilus masculinus) compressing matrix of cone swells the transmission pressure slider, by roller pressure is passed to abrasive sheet, abrasive sheet and inner surface of cylinder liner are fitted, thereby produce the top gem of a girdle-pendant and grind pressure, the grinding agent feeder injects grinding agent by nozzle in cylinder sleeve simultaneously, and work piece inner surface is cut, rolling and processing.After the completion of processing, the connecting rod stop motion, last pressure-raising bar makes the abrasive sheet return by turn, pin.Sealing slide block and baffle plate can stop grinding agent to enter in the honing lapping head.
Adopt technology of the present invention and equipment, can make inner surface of cylinder liner form rational surface characteristics, have certain roughness and cured layer and necessary residual compressive stress, help forming discontinuous and equally distributed store oil cave, improve the fatigue resistance of inner surface of cylinder liner, improved the wear resistence and the service life of cylinder sleeve, satisfied the instructions for use that supercharged engine improves power, improved service life more than 10%, removed the influence of phosphatization processing environmental pollution.
