Problems solved by technology

The traditional method adopts manual assembly, which needs to be pressed into the installation hole of the oil passage vigorously while aligning the bolt holes, which is likely to cause the following risks:
[0004] (1) It cannot be installed in place at one time, and multiple adjustments are required, resulting in a long installation cycle;
[0005] (2) When pressing into the mounting hole vigorously, it is easy to cause the sealing ring to be skewed or even fall off, resulting in engine oil leakage;
[0006] (3) When tightening the fixing bolts, because the oil control valve is not seated accurately, the bolts cannot fit the mounting surface, and the tightening torque attenuates
However, it does not specifically involve the process equipment for installing the oil control valve

Abstract

The invention relates to an installation fixture for an engine oil control valve. The installation fixture comprises a fixture body and is characterized in that the fixture body comprises a T-shaped handle, a guide sleeve of which the left end is cooperatively connected with the T-shaped handle, and a guide pin positioning block in positioning connection with the outer side surface of the guide sleeve, and the right end of the guide pin positioning block is flush with the right end of the guide sleeve; the fixture body further comprises a guide pin vertically connected to the right end of theguide pin positioning block; and the right end of the guide sleeve is provided with an avoiding notch. According to the installation fixture, the assembling quality and the engine performance can be ensured, the assembling time is shortened, the manpower labor is decreased, the assembling cost is reduced, in addition, the structure is simple, and using is portable and convenient.

Description

technical field [0001] The invention relates to an engine, in particular to a mounting fixture for an oil control valve. Background technique [0002] Oil control valve is an important part of automobile engine, and its assembly quality directly affects the performance of the engine. In order to ensure the accurate control function of the oil control valve during engine operation, it is necessary to ensure that there is no quality risk in the assembly process, that is, it is accurately installed in place, and the sealing ring is correctly seated after installation, and the torque has no attenuation. [0003] Due to the particularity of the structure, there is a large resistance between the sealing ring and the wall of the installation hole during the installation process. The traditional method adopts manual assembly, which needs to be pressed into the installation hole of the oil passage vigorously while aligning the bolt holes, which is likely to cause the following risks...
