Injection pipe detection tool

Abstract

The invention provides an oil jet tube detection tooling which comprises a base, a positioning mechanism and a detection mechanism. The positioning mechanism is fixedly arranged on the base to position an oil jet tube assembly. The positioning mechanism is provided with a liquid discharge hole. The liquid discharge hole is communicated with an oil supply hole in the oil jet tube assembly. The detection mechanism comprises a size detection block and a direction detection block. One end of the direction detection block is fixedly arranged on the size detection block through a pad. The other endof the direction detection block is spaced from the size detection block. A groove is arranged in the size detection block. An injection hole is arranged in the direction detection block. The injection hole is aligned with the groove. According to the oil jet tube detection tooling provided by the invention, the size and the oil jet direction of an oil jet tube are simultaneously detected; the penetrating direction of the groove is perpendicular to the surface of the size detection block; an employee can directly look down onto the gap between the oil jet tube and the groove, which facilitatesthe detection operation; and the problem that the employee difficultly observes a profile groove which is arranged in the surface of a detection block in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of fuel injection pipe detection, in particular to a fuel injection pipe detection tool. Background technique [0002] In order to meet the lubrication requirements of gears and bearings in dual-clutch gearboxes, an oil injection pipe is required to forcibly lubricate the gears and bearings, and in order to meet the compactness of the gearbox system, the structure of the oil injection pipe is usually designed to be more complicated, and Small clearances with gears and bearings. In order to ensure that the oil injection pipe does not interfere with other parts and ensure that the lubricating oil can be sprayed to the position of the gear and bearing, the oil injection direction of the oil injection pipe is required to have good precision, but after the gearbox is assembled, it is usually difficult to observe and To measure the state and position of the fuel injection pipe installation, for this purpose speci...

Problems solved by technology

However, since the gap between the fuel injection pipe and the profiling groove 21 is not easy to observe or measure, this brings great difficulties to the detection operation of the employees. Therefore, the profiling groove 21 can only detect the size of the fuel injection pipe, but cannot detect the fuel injection direction of the fuel injection pipe

In addition, due to the flexible adjustment of the fuel injection pipe in the actual loading process to meet the actual requirements of loading, the existing fuel injection pipe detection tool has a small tolerance of the profiling groove 21 and the accuracy is too high , for some qualified fuel injection pipes used in actual loading, they are judged as unqualified on the existing fuel injection pipe inspection tooling, which undoubtedly increases the defective rate of parts and the cost of repair or scrap
