Abstract
The utility model discloses a stroke measurement assembly of an oil injector, and the stroke measurement assembly is used for detecting the stroke of the oil injector when an engine is installed. A rocker booster is arranged in a rocker of the oil injector, a dial indicator frame is connected with a dial indicator fixing adapter through a connecting screw, the dial indicator fixing adapter is fixed on a rocker chamber shell, a dial indicator lengthening rod for the dial indicator is arranged on the dial indicator frame through a connecting frame, and the dial indicator lengthening rod is in contact with a gasket of an oil injector spring. The rocker booster is driven by using a wrench, an oil injector plunger moves up and down, and the stroke range of the oil injector can be accurately measured. The stroke measurement assembly has the advantages of simple structure, convenience in installation and capability of easily and accurately measuring the stroke of the oil injector, and is suitable for multiple types of machines.
Description
Technical field
The utility model relates to the testing tool technical field, is a kind of instrument that detects the fuel injector stroke when engine is installed specifically.
Background technology
At present, when assembled engines, with the fixing clock gauge of Magnetic gauge stand, regulate dial framework, indicator is dropped on the pad of fuel injector spring, tool using pulling rocking arm is measured the stroke of fuel injector.Because rocking arm is an irregular part, shakes inconvenience, strength is inhomogeneous, makes the data of measuring the fuel injector stroke inaccurate, than being easier to damage clock gauge.And only adopt Magnetic gauge stand and clock gauge, limit by indicator length and shape, cause using type to be limited to.
Summary of the invention
Measure inaccurate, the restricted deficiency of usable range of fuel injector run-length data in order to overcome existing method; The goal of the invention of the utility model is to provide a kind of fuel injector stroke measurment assembly; Can be accurately, be convenient for measuring the fuel injector stroke, and can be suitable for different types of machines.
For realizing above-mentioned purpose; The utility model comprises the rocking arm mobility aid; the rocking arm mobility aid is installed on the fuel injector rocking arm, and dial holder is connected with the clock gauge fixed adapter through connecting screw rod, and the clock gauge fixed adapter is fixed on the rocker arm chamber housing; clock gauge is contained on the dial holder through web member with the clock gauge extension rod, and the clock gauge extension rod contacts with the pad of fuel injector spring.Utilize spanner to drive the rocking arm mobility aid, to measure the fuel injector stroke.
The utility model is compared with prior art, and is simple in structure, easy for installation, can be easily, accurately measure the fuel injector stroke, and be applicable to different types of machines.
Description of drawings
Fig. 1 is the three-dimensional sketch of the utility model.
Fig. 2 is the three-dimensional sketch of the rocking arm mobility aid 7 of the utility model.
Embodiment
Like Fig. 1, shown in Figure 2, clock gauge fixed adapter 2 is fixed on the rocker arm chamber housing through its part that is threaded, and dial holder 4 is connected with clock gauge fixed adapter 2 through connecting screw rod 3; Clock gauge 5 usefulness clock gauge extension rods 1 are contained on the dial holder 4 through web member 6; Select suitable clock gauge extension rod 1, adjust dial holder 4, clock gauge extension rod 1 is just in time dropped on above the fuel injector spring on the pad; Rocking arm mobility aid 7 is installed on the fuel injector rocking arm; Utilize spanner to drive the rocking arm mobility aid, the fuel injector plunger is moved up and down, can accurately measure the travel range of fuel injector.
