Description
Technical Field
The utility model relates to an engine oil rail connects, concretely relates to engine oil rail connects oilhole fault detection device.
Background
The gasoline engine oil rail joint is used as an important part of an engine and plays a role in connecting a fuel oil pipe with an oil rail and a cylinder body, and if the part fails, for example: the running performance of the vehicle can be directly influenced by blockage and over-tolerance (small) of the diameter of the inner hole, and the phenomena of over-small oil pumping amount and incapability of acceleration occur if the oil pumping amount is small. Serious faults such as oil rail joint blockage, no oil pumping, abnormal ignition or running of a vehicle and the like can occur.
At present, oil rail joints in the industry are usually made of copper alloy metal materials, and have good cutting performance and heat dissipation performance. The oil rail joint is generally processed by the steps of cutting raw materials, heating, forging and pressing, and machining to finally form a finished product. Because the oil rail joint is a cylinder, a hole needs to be drilled in the center, the design standard of the aperture is 0.8mm-1.2mm, and the hole is formed by processing a drill bit on a numerical control lathe. Because the aperture is less, the drill bit often appears fracture or the sword phenomenon of collapsing in the course of working, and lathe continuation processing can lead to the oilhole to block up or the processing fault not in place, influences vehicle functionality.

Detailed Description
The invention is described below with reference to the accompanying drawings:
referring to fig. 1, the machining process is optimized to increase the oil hole diameter detection link, a detection tool is added, an oil rail joint 9 is fixed on a tool bottom plate 1, an air inlet pipe joint 6 and an air outlet pipe joint 5 of an air outlet pipe are added on the left side and the right side of the oil hole in butt joint, a micro gas flow detection sensor 11 is connected to one end of the air outlet pipe of the air inlet pipe joint 5, the flow detection sensor 11 is connected with an alarm lamp and an air cylinder execution mechanism, and a whole detection system is provided.
The cylinder actuating mechanism comprises a clamping pressure head 8 and a clamping cylinder 10; wherein, the clamping pressure head 8 is provided with an air outlet hole, and the air pipe joint 5 of the air outlet pipe is connected with the air outlet hole of the clamping pressure head 8.
And (3) adding a detection tool, then enabling the high-pressure gas to enter an oil hole of an oil rail joint 9 through 0.5kpa, testing the air flow by taking a qualified product as a reference, and assuming that the flow value of the qualified product is 3.0-4.0.
If the connector is broken and blocked, the ventilation flow sensor detects no flow, the product is NG, the sensor outputs a signal to the PLC, and the host feeds back to the NG pushing cylinder 4 to push out a defective part.
Specifically, the start button 2 is started, the airflow enters the oil rail joint from the air inlet pipe and enters the air outlet pipe through the clamping pressure head, and the flow rate detection sensor detects the flow rate value of the air outlet pipe at the moment;
if the aperture of the oil hole is smaller and the flow value detected by the gas flow sensor is less than 3.0, the product is NG.
If the hole diameter of the oil hole is larger, and the flow value detected by the gas flow sensor is larger than 4.0, the product is NG.
