Abstract
The invention discloses a cleaning method for an inner hole of a piston pin of an engine, which belongs to the technology field of piston pin processing technology. The cleaning method is characterized in that the mechanical physical method is adopted to remove accumulated carbon and oxide scales of the inner hole of the piston pin, the operation process is that the piston pin after the primary processing is arranged on a horizontal hole plate, the opening end of the inner hole is upward, and then a pneumatic spray gun is used for spraying the inhaled sands pointed at the inner hole for 5 to 10 minutes with the gas pressure of 0.7 to 1.0MPa. The method of the invention does not need chemical solution, which can remove the accumulated carbon and oxide scales in the inner hole of the piston pin due to the carburization only by spraying sand, thus having no problems of chemical pollution and waste liquid treatment, having low cost, being safe to human bodies and environment, strengthening and smoothening the surface of a workpiece and improving the service performance.
Description
Technical field
The present invention relates to a kind of engine gudgeon pin processing technology, particularly engine gudgeon pin bore cleaning method.
Background technology
Engine gudgeon pin need carry out Carburization Treatment in process, can stay carbon distribution and oxide skin on inside and outside surface after the carburizing, and these carbon distributions and oxide skin will be polluted main frame lubricating oil as not removing, even causes oil duct to stop up, and is accidents caused.Carbon distribution and oxide skin for piston pin cylindrical and end face can obtain removing in the fine finishining of carrying out subsequently (cylindrical grinding, face grinding and chamfering), and gudgeon pin bore no longer carries out machined, so will carry out bore cleaning after the carburizing because of there not being the requirement of cooperation.The present method that adopts physical chemistry to combine to the cleaning of gudgeon pin bore, the utilization chemical solution soaks, dissolves carbon distribution and oxide skin, clean again, this method will be used chemicals, and there is a liquid waste processing problem, cost height not only also can cause to operating personnel's injury with to the pollution of environment.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of production cost low, help health and environmental protection, and can also improve the engine gudgeon pin bore cleaning method of workpiece serviceability.
Technical scheme of the present invention is: engine gudgeon pin bore cleaning method comprises that endoporus removal carbon distribution and oxide skin and endoporus clean, and improvements are that described endoporus is removed carbon distribution and oxide skin adopts mechanical-physical removal method, and operating process is:
(1) will place on the flat orifice plate that anhydrates through the engine gudgeon pin after preliminary working and the Carburization Treatment is neat, the gudgeon pin bore openend makes progress, and described orifice plate is done uniform rotation under driven by motor, and rotating speed is 80～200r/min;
(2) adopt pneumatic spray gun to suck sand, with the gas pressure of 0.78～1.0MPa sand is ejected into gudgeon pin bore, injecting time 7～10 minutes, described sand are crossed 60～80 purpose sieves, extracting screen underflow.
Further scheme is: described sand is generally selected clean yellow ground for use; During sandblast, aim at gudgeon pin bore by operator's pistol and spray; Perhaps during sandblast, along with the rotation of orifice plate, spray gun is contained on the anchor clamps, makes periodic wobble; Described orifice plate and piston pin are placed in the cleaning bucket, and sand is reused.
Adopt method of the present invention not need chemical solution, only depend on the injection of sand just can effectively remove carbon distribution and the oxide skin that stays because of carburizing in the gudgeon pin bore, there are not chemical contamination and liquid waste processing problem, thereby cost is low, to human body and Environmental security, and in the sandblast process, sand pressure is bigger, and workpiece is produced hammer action, reach surface peening and smooth effect, help improving the workpiece serviceability.
The specific embodiment
Further specify the present invention below by embodiment.
Example one: 400 neatly are placed on the horizontal orifice plate through the engine gudgeon pin after preliminary working and the Carburization Treatment, the gudgeon pin bore openend upwards, orifice plate by driven by motor with the uniform rotation of 100r/min rotating speed; Operator's hand-held pneumatic spray gun, the clean yellow ground of the 60 order granularities that will suck with the gas pressure of 0.78MPa is aimed at gudgeon pin bore and was sprayed 8 minutes, and the operator should continuous mobile spray gun position, adjusts spray angle, to guarantee cleaning effect.
Example two: 800 neatly are placed on the horizontal orifice plate through the engine gudgeon pin after preliminary working and the Carburization Treatment, the gudgeon pin bore openend upwards, orifice plate by driven by motor with the uniform rotation of 180r/min rotating speed; With pneumatic spray gun clamping on the anchor clamps that are positioned at above the piston pin, the clean yellow ground of the 80 order granularities that will suck with the gas pressure of 0.88MPa is aimed at gudgeon pin bore and was sprayed 7 minutes, during sandblast, spray gun is 2 seconds periodic wobble with the anchor clamps working head as the cycle, guarantees cleaning effect.Used yellow ground is collected the back by the cleaning bucket and is reused.
Claims (4)
1. an engine gudgeon pin bore cleaning method comprises that endoporus removal carbon distribution and oxide skin and endoporus clean, and it is characterized in that described endoporus is removed carbon distribution and oxide skin adopts mechanical-physical removal method, and operating process is:
(1) will neatly be placed on the horizontal orifice plate through the engine gudgeon pin after preliminary working and the Carburization Treatment, the gudgeon pin bore openend makes progress, and described orifice plate is done uniform rotation under driven by motor, and the orifice plate rotating speed is 80～200r/min;
(2) adopt pneumatic spray gun to suck sand, with the gas pressure of 0.78～1.0MPa sand is ejected into gudgeon pin bore, injecting time 7～10 minutes, described sand are crossed 60～80 purpose sieves, extracting screen underflow.
2. by the described engine gudgeon pin bore cleaning method of claim 1, it is characterized in that: during sandblast, aim at gudgeon pin bore by operator's pistol and spray.
3. by the described engine gudgeon pin bore cleaning method of claim 1, it is characterized in that: during sandblast, the spray gun clamping is made periodic wobble on anchor clamps.
4. by the described engine gudgeon pin bore cleaning method of claim 1, it is characterized in that: described orifice plate and piston pin are placed in the cleaning bucket, and sand is reused.
