Engine rocker arm oil hole permeability automatic detection device

Abstract

The invention discloses an engine rocker arm oil hole permeability automatic detection device. The device comprises a gas detection table, a feeding robot and a discharging robot, wherein the feedingrobot and the discharging robot are located on the two sides of the gas detection table; a rocker arm positioning mechanism, a rocker arm jacking mechanism and a rocker arm sensing device are arrangedon the gas detection table; the feeding robot places a rocker arm on the rocker arm positioning mechanism of the gas detection table; the rocker arm jacking mechanism is used for guiding and fixing;the rocker arm positioning mechanism is provided with a gas inlet and a gas outlet; the gas inlet is externally connected with a gas source; the gas outlet is aligned with an oil hole of the rocker arm; an air pressure sensor is arranged on the inner side of the gas inlet; airflow entering the gas inlet enters the oil hole of the rocker arm through the gas outlet; pressure changes are detected through the air pressure sensor; and if an oil way is unobstructed, pressure is unchanged; and if the oil way is obstructed, the pressure is increased. According to the device of the invention, 100% detection of the permeability of the oil hole of the engine rocker arm can be realized; unmanned automatic engine oil hole permeability detection is adopted, and therefore, the detection efficiency is improved, the detection accuracy and consistency rate are improved, manual deviation is avoided, and the operating cost and risk of companies are reduced.

Description

technical field [0001] The invention relates to the field of permeability detection of an engine rocker arm oil hole, in particular to an automatic detection device for the oil hole permeability of an engine rocker arm. Background technique [0002] When the engine rocker arm reciprocates in the engine, the engine oil enters the roller pin shaft through the oil hole of the engine rocker arm to lubricate the oil passage and the rollers, reduce the wear of the rollers and prolong the service life of the engine. If the oil hole of the rocker arm or the oil hole of the roller pin is blocked, the engine alarm will be triggered, the engine will sound abnormally, the engine will be weak, and cannot be used normally. Therefore, the permeability of the oil hole of the engine rocker arm must be 100% guaranteed. [0003] The oil hole permeability test of the existing engine rocker arm is a manual oil hole probe insertion test, which is a traditional detection method. In order to ensure...

Problems solved by technology

If the oil hole of the rocker arm or the oil hole of the roller pin shaft is blocked, the engine alarm will be triggered, the engine will sound abnormally, the engine will be weak, and cannot be used normally, so the oil hole permeability of the engine rocker arm must be 100% guaranteed

[0003] The oil hole permeability test of the existing engine rocker arm is a manual oil hole probe insertion test, which is a traditional detection method. In order to ensure the passage of each engine oil hole without clogging, 100% oil must be carried out. Hole permeability detection, while manual detection is inefficient, labor-intensive, and labor-intensive. At the same time, the position of the oil hole of the rocker arm and the depth of the oil hole of the rocker arm make the detection difficult objectively, and manual detection has human judgment bias. The consistency rate and accuracy of rocker oil hole detection cannot be guaranteed 100%, and there is uncertainty. Once the judgment is missed, the client will claim, which will increase operating costs and risks for the company
