Problems solved by technology

Due to the small hole diameter, the drill bit often breaks or breaks during the machining process. Continued machining on the lathe will cause the oil hole to be clogged or the machining is not in place, which will affect the functionality of the vehicle.

Embodiment Construction

[0018] The following is a description of this work in conjunction with the accompanying drawings:

[0019] refer to figure 1 , now optimize the processing technology to increase the oil hole diameter detection link, add a detection tool, the oil rail joint 9 is fixed on the tooling bottom plate 1, and the inlet pipe air pipe joint 6 and the air outlet pipe air pipe joint 5 are docked on the left and right sides of the oil hole, Wherein one end of the outlet pipe trachea joint 5 is connected to a micro-gas flow detection sensor 11 at the outlet pipe, and the flow detection sensor 11 is connected with an alarm lamp and a cylinder actuator to form a complete detection system.

[0020] The cylinder actuator includes a clamping head 8 and a clamping cylinder 10; wherein the clamping head 8 is provided with an air outlet, and the outlet pipe trachea joint 5 is connected to the air outlet of the clamping head 8.

[0021] After adding a detection tool, the high-pressure gas 0.5kpa en...

Abstract

The invention discloses an engine oil rail connector oil hole fault detection system and method. The system comprises a fixing device used for fixing an oil rail connector, an air cylinder executing mechanism, an oil rail connector oil hole fault detection device and a control circuit, wherein the flow detection sensor is arranged on the air outlet pipeline and used for detecting an air flow valuein the air outlet pipeline and sending a corresponding air flow induction signal to the control circuit when the air flow value exceeds a certain set value; and the control circuit controller controls the cylinder actuating mechanism according to the airflow sensing signal. The detection method can achieve a 100% effective monitoring effect on liquid and gas flow components, defective products are prevented, and the defects of the process are overcome.

Description

technical field [0001] The invention relates to an engine oil rail joint, in particular to an engine oil rail joint oil hole fault detection system and method. Background technique [0002] As an important part of the engine, the fuel rail connector of the gasoline engine plays the role of connecting the fuel pipe with the fuel rail and the cylinder block. If the part fails, such as: blockage, inner hole diameter out of tolerance (too small), it will directly affect the driving performance of the vehicle , light pump oil volume is too small, the phenomenon of weak acceleration. In severe cases, such as blockage of the oil rail joint, there will be serious failures such as not pumping oil, and the vehicle cannot be ignited or driven normally. [0003] At present, the oil rail joints in the industry are usually made of copper alloy metal materials, which have good cutting performance and heat dissipation performance. The usual processing technology of fuel rail joints is raw...
