Abstract
The utility model relates to a special tool for measuring the stroke of an oil sprayer, which is simpler in structure, more convenient to operate and more accurate in measurement. The special tool comprises a liquid crystal readable instrument and an instrument mounting rack, wherein the readable instrument is provided with a base, and a measuring mandril of the readable instrument is sleeved into the base of the readable instrument, and is capable of freely and vertically moving. The special tool is characterized in that the instrument mounting rack is provided with a through hole along the axis direction, the side part of the instrument mounting rack is provided with a fastening device for connecting the readable instrument with the instrument mounting rack, the measuring mandril of the readable instrument penetrates through the through hole of the instrument mounting rack after passing through the bottom of an instrument, the tail part of the measuring mandril is exposed outside the through hole of the instrument mounting rack, the measuring mandril vertically slides in the through hole of the instrument mounting rack, and during measurement, the upper end of the measuring mandril sleeved into the instrument mounting rack is contacted with the readable instrument, and the lower end of the measuring mandril sleeved into the instrument mounting rack is contacted with a gasket in the oil sprayer. When the measuring mandril is in close fit between the readable instrument and the oil sprayer, the stroke of the oil sprayer on the readable instrument can be read, so that standard gaskets with different thicknesses can be conveniently replaced in the oil sprayer, and accordingly the stroke of the oil sprayer is adjusted in a permissible range.
Description
Technical field
The improvement invention that the utility model relates to a kind of Auto repair shop repairs the special measurement instrument of oil sprayer stroke.
Background technique
In the prior art, oil sprayer is the vitals that maintains motor operation, by oil injector body, oil nozzle, bearing, spring composition, by oil nozzle oil-feed port pump, enter high pressure oil, in oil injector body, produce High Pressure to the conical surface, when oil pressure exceedes fixed value, oil nozzle spool is opened, and high pressure oil sprays from nozzle aperture, be vaporific, in motor cylinder barrel, burn, piston is moved repeatedly, the main test item of oil sprayer is the seal degree of jet pressure, injector stroke, angle of apray, spray pattern and oil nozzle.When the pad wearing and tearing in oil sprayer, while causing injection stroke to change, can bring diesel engine power decline, shake, black smoke from exhaust, machine run sound undesired, when affecting the normal operation of vehicle, just need docking oil sprayer.Look into Chinese patent, notice of authorization number is the oil sprayer stroke measurment assembly of CN202582433U, rocking arm driving-aid need to be arranged on oil sprayer rocking arm, dial holder is connected with dial indicator ABAP Adapter by connecting screw rod, dial indicator ABAP Adapter is fixed on rocker arm chamber housing, dial indicator is contained on dial holder through link with dial indicator extension bar, dial indicator extension bar contacts with the pad of oil sprayer spring, utilize spanner to drive rocking arm driving-aid, oil sprayer plunger is moved up and down, also can measure oil sprayer range of operation, but this structure is still felt some trouble with operation.
Summary of the invention
In view of the problem that known technology exists, it is simpler that the purpose of this utility model aims to provide a kind of structure, more convenient to operate, measures the special tool of measuring more accurately oil sprayer stroke.
The utility model completes as follows, the special tool of this measurement oil sprayer stroke, comprise the readable instrument of a liquid crystal and meter erection fixture, readable instrument has a base, the measurement top stem casing of readable instrument is contained in the base of readable instrument, can move by easy on and off, it is characterized in that meter erection fixture is axially arranged with a through hole at it, at the sidepiece of its meter erection fixture, be provided with the fastening device that readable instrument is connected with scaffold, the measurement push rod of described readable instrument runs through the through hole of instrument calibration through instrument bottom, its afterbody of measuring push rod exposes outside the through hole of meter erection fixture, described measurement push rod slides up and down in the through hole of meter erection fixture, when measuring, its upper end of measurement push rod being sleeved in meter erection fixture contacts with readable instrument, its lower end contacts with the pad in oil sprayer.
When measuring push rod, between readable instrument and oil sprayer, during close-fitting, can in readable instrument, read oil sprayer stroke, to change different-thickness specified standard pad in oil sprayer, make oil sprayer stroke adjust to allowed band.
The utility model, compared with known technology, has structure simple especially, and it is convenient especially to operate, and it is accurate especially to measure, and can be as accurate as 0.01 micron.
