Abstract
The invention discloses a device for measuring the coaxiality of an oil injector installation hole and an oil injector head installation hole of a cylinder cover. The device consists of an expansion mandrel, a handle, expansion balls, expansion ball installation holes, compression springs, a front rod, a measuring rod installation groove, a screw, a dial test indicator, a measuring rod and a measuring head. The expansion mandrel slides in the oil injector installation hole of the cylinder cover in all directions according to the measuring requirement, and simulates the axis of the oil injector installation hole of the cylinder cover; the highest reading of the inner diameter of the oil injector head installation hole is measured by using the lowest reading of the inner diameter of the oil injection installation hole, which is measured by the dial test indicator, as reference; the device for measuring the coaxiality of the oil injector installation hole and the oil injector head installation hole of the cylinder cover is novel in design and structure, simple in measuring process, and convenient to use; and a measuring result is accurate.
Description
Technical field
The present invention relates to a kind of machine parts measurement utensil, especially the cylinder cap fuel injector mounting hole is to nozzle tip mounting hole coaxality measurement device.
Background technology
At present, the cylinder cap fuel injector mounting hole is the important quality project that affects the cylinder head performance on nozzle tip mounting hole right alignment; Carry out observational measurement with feeler gauge, can only judge that whether part is qualified, the improvement that can not provide data to instruct in detail processing technology, affect the quality of part; By three-dimensional, detect, the process of measurement complexity, expense is high.
Summary of the invention
The invention provides a kind of cylinder cap fuel injector mounting hole to nozzle tip mounting hole coaxality measurement device, expanding mandrel is by the swollen pearl contact cylinder cap fuel injector mounting hole inwall slided, the gauge head of dial test indicator refers at nozzle tip mounting hole inwall, this measuring appliance project organization novelty, process of measurement is simple, and measurement result is accurate.
The technical solution adopted for the present invention to solve the technical problems is: the cylinder cap fuel injector mounting hole, to nozzle tip mounting hole coaxality measurement device, is comprised of expanding mandrel, handgrip, swollen pearl, swollen pearl mounting hole, Compress Spring, front bar, measuring staff mounting groove, screw, dial test indicator, measuring staff, gauge head.Expanding mandrel laterally is three swollen pearl mounting holes that equilateral triangle distributes, and in each swollen hole of bead, pack into Compress Spring, swollen pearl carry out reducing with the reducing instrument to swollen micropylar opening after being pressed into swollen pearl; The swollen pearl of three rows that expanding mandrel vertically is evenly distributed, the height that each swollen pearl exceeds the expanding mandrel cylindrical is consistent, expansive force is even, and expanding mandrel is by the swollen pearl contact cylinder cap fuel injector mounting hole inwall slided, expanding mandrel simulation cylinder cap fuel injector mounting hole axis; The expanding mandrel left end is provided with front bar, and right-hand member is provided with handgrip; Measuring staff is installed in the measuring staff mounting groove of the front bar left end that stretches out the nozzle tip mounting hole makes gauge head refer at nozzle tip mounting hole inwall and be screwed measuring staff, it is benchmark that the dial test indicator of take records nozzle tip mounting hole internal diameter least count a, and the index dial zero-bit of dial test indicator is forwarded on pointer; Expanding mandrel rotate 90 ° in dial test indicator to record nozzle tip mounting hole internal diameter full-scale reading be b, the cylinder cap fuel injector mounting hole is to nozzle tip mounting hole right alignment
The invention has the beneficial effects as follows, the cylinder cap fuel injector mounting hole can be measured qualitative data accurately to nozzle tip mounting hole coaxality measurement device, promotes process modification, has guaranteed product quality; This measuring appliance is easy to use, reduces expenses 95%.
