Abstract
The utility model discloses an instrument for measuring the coaxiality between an oil injector mounting hole and an oil injection head mounting hole in a cylinder cover. The instrument is composed of an expandable mandrel, a handle, an expanding ball, an expanding ball mounting hole, a compression spring, a front rod, a measuring bar installing groove, a screw, a lever type dial indicator, a measuring bar and a measuring head, wherein the expandable mandrel is in contact with the inner wall of the oil injector mounting hole in the cylinder cover, and the measuring head of the lever type dial indicator points to the inner wall of the oil injection head mounting hole; the expandable mandrel imitates the axis of the oil injector mounting hole; and through taking the minimum readout of the measured inside diameter of the oil injection head mounting hole as reference, the maximum readout of the measured inside diameter of the oil injection head mounting hole is measured. The instrument is novel in design structure, accurate in measuring results, simple in measuring program, and convenient to use.
Description
Technical field
The utility model relates to a kind of machine parts measurement utensil, and especially the cylinder cap fuel injector mounting hole is to nozzle tip mounting hole right alignment measurer.
Background technology
At present, the cylinder cap fuel injector mounting hole is the important quality project that influences the cylinder head performance to nozzle tip mounting hole right alignment; Carry out observational measurement with feeler gauge, can only judge whether part is qualified, the improvement that can not provide data to instruct processing technology in detail influences the quality of part; Detect process of measurement complexity, expense height with three-dimensional.
Summary of the invention
The utility model provides a kind of cylinder cap fuel injector mounting hole to nozzle tip mounting hole right alignment measurer, expanding mandrel is by the bloated pearl contact cylinder cap fuel injector mounting hole inwall that slides, the gauge head of dial test indicator refers at nozzle tip mounting hole inwall, this Design of Measuring Tools novel structure, process of measurement is simple, and measurement result is accurate.
The technical scheme that its technical matters that solves the utility model adopts is: the cylinder cap fuel injector mounting hole is made up of expanding mandrel, handgrip, the pearl of expanding, the pearl mounting hole that expands, compression spring, preceding bar, measuring staff mounting groove, screw, dial test indicator, measuring staff, gauge head nozzle tip mounting hole right alignment measurer.Expanding mandrel laterally is three bloated pearl mounting holes that equilateral triangle distributes, and the compression spring of packing in each bloated hole of bead, the pearl of expanding carry out reducing with the reducing instrument to bloated micropylar opening after being pressed into the pearl of expanding; The bloated pearl of three rows that expanding mandrel vertically is evenly distributed, each bloated pearl exceeds the height unanimity of expanding mandrel cylindrical, expansive force is even, and expanding mandrel is by the bloated pearl contact cylinder cap fuel injector mounting hole inwall that slides, expanding mandrel simulation cylinder cap fuel injector mounting hole axis; The expanding mandrel left end is provided with preceding bar, and right-hand member is provided with handgrip; Measuring staff is installed in the mounting hole of oil sprayer left end stretches out the measuring staff mounting groove of preceding bar left end of nozzle tip mounting hole refers at nozzle tip mounting hole inwall and with the fixing measuring staff of screw gauge head, recording nozzle tip mounting hole internal diameter least count with dial test indicator is that a is a benchmark, and the index dial zero-bit of dial test indicator is forwarded on the pointer; To record nozzle tip mounting hole internal diameter full-scale reading be b to dial test indicator during expanding mandrel rotated 90 °,
The beneficial effects of the utility model are that the cylinder cap fuel injector mounting hole can be measured qualitative data accurately to nozzle tip mounting hole right alignment measurer, promotes process modification, has guaranteed product quality; This measurer is easy to use, reduces expenses 95%.
