Multi-spray-nozzle air-pressure pulse chip clearing system for piston chip clearing and control method

Abstract

The invention discloses a multi-spray-nozzle air-pressure pulse chip clearing system for piston chip clearing and a control method. The system comprises oil hole spray nozzles, pin hole spray nozzles, annular groove spray nozzles and a spark plug hole spray nozzle, wherein the oil hole spray nozzles are installed on a rack A and the direction of the air outlet ends of the oil hole spray nozzles is in parallel with the axis direction of a piston supporting seat; the pin hole spray nozzles are installed on a rack B and the direction of the air outlet ends of the pin hole spray nozzles is perpendicular to the axis direction of the piston supporting seat; the annular groove spray nozzles are installed on the rack B and the direction of the air outlet ends of the annular groove spray nozzles is perpendicular to the axis direction of the piston supporting seat; and the spark plug hole spray nozzle is installed on the rack B and the direction of the air outlet end of the spark plug hole spray nozzle is in parallel with the axis direction of the piston supporting seat. The control method comprises six process steps in the actual working process. The multi-spray-nozzle air-pressure pulse chip clearing system for piston chip clearing and the control method aim at clearing chips produced during piston machining and preventing cross pollution of the chips on different machining surfaces during chip clearing process.

Description

technical field [0001] The invention relates to a multi-nozzle air pressure pulse chip cleaning system and control method for piston chip cleaning. Background technique [0002] The piston is the "heart" of the automobile engine, which bears alternating mechanical loads and thermal loads, and is one of the key components in the engine with the worst working conditions. The function of the piston is to withstand the gas pressure and transmit it to the connecting rod through the piston pin to drive the crankshaft to rotate. The top of the piston is also an integral part of the combustion chamber. [0003] A large amount of metal shavings will be produced during the production of pistons, and surface cleaning of swarf is an essential process. Under the current technical conditions, ultrasonic chip cleaning or manual chip cleaning are generally used. Ultrasonic chip cleaning is cumbersome, takes a long time and cannot be completely cleaned, resulting in waste water; manual pne...

AI Technical Summary

Problems solved by technology

Ultrasonic chip cleaning is more troublesome, it takes a long time and cannot be completely cleaned, resulting in waste water; manual pneumatic blowing and chip removal is labor-intensive, and human negligence is likely to cause dead ends in chip cleaning

In the process of industrialization, due to the large demand for pistons, the conventional artificial chip removal method cannot meet the chip removal requirements, so the emergence of automatic chip removal equipment is an inevitable result
