Abstract
The utility model relates to a non-vertical panel hole depth measurement device consisting of a bore dial gauge, a measurement rod and a positioning central shaft. The positioning central shaft cooperates with the measurement rod through a small clearance, a gauge bracket holding the bore dial gauge is arranged on the upper part of the central shaft, a positioning sleeve is arranged on the lower part of the central shaft. The measurement rod extends out of the positioning sleeve; a standard ring simulating the hole for measurement is provided for the device, the upper and lower inclination and the hole depth of the standard ring is the same as the object for measurement, the diameter of the standard ring is the same as the external diameter of the positioning sleeve. The utility model adopts the standard ring to set the zero point for the bore dial gauge, comparing with the technology known in the art, the utility model is convenient, fast and accurate, especially for large batch of products.
Description
Technical field
The utility model relates to a kind of survey instrument that is used to measure the non-perpendicular end-face hole degree of depth of part.
Background technology
Part oil injector hole bottom surface to cylinder head bottom surface required distances such as engine cylinder cap are often higher, because cylinder head bottom surface and oil injector hole axis out of plumb, and relatively difficulty of hole depth is measured in part inside in the other end in hole therefore.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, measures accurately, and is convenient to use, is particularly useful for the non-perpendicular end-face hole depth survey instrument that bulk article is measured.
The technical solution of the utility model is: non-perpendicular end-face hole depth survey instrument, comprise dial gauge, sounding rod, improvements are positioning core axles that the sounding rod periphery is provided with it little clearance fit, the positioning core axle upper end is provided with the dial framework that clamps dial gauge, the positioning core axle lower end is provided with locating sleeve, the measuring junction of sounding rod stretches out outside the locating sleeve, between dial gauge and the sounding rod spring is arranged.
This survey instrument is furnished with standard ring, before being used for measuring dial gauge is adjusted to zero-bit, the upper and lower end face angle of this standard ring α is consistent with tested metering-orifice both ends of the surface angle, endoporus is vertical with the upper surface, interior hole depth is consistent with measured hole depth standard value, and diameter of bore is consistent with described locating sleeve external diameter; Described dial framework is threaded with the positioning core axle upper end, and dial framework one side is provided with shaft orientation opening groove and trip bolt.
The utility model is simple in structure, makes easily, and location, adjustment, clamping are all easily reliable.During measurement, utilize the standard ring of the tested situation of simulation to adjust dial gauge to zero-bit, adopt comparative measurement method to measure the measured hole degree of depth, convenient to use, the hole depth that is particularly useful for bulk article is measured, as long as once adjust, but continuous coverage, surface readings is the poor of hole depth and standard value, measures accurately.
Description of drawings
Fig. 1 is the utility model agent structure synoptic diagram;
Fig. 2 is the utility model adapted standard ring structural representation.
Embodiment
As figure, dial gauge 1 is contained on the dial framework 3, clamp by trip bolt 2, dial framework 3 is threaded with positioning core axle 7, sounding rod 5 and the little clearance fit of positioning core axle, the sounding rod upper end is held out against by spring 4, and the lower end is that measuring junction stretches out outside the locating sleeve 8 that is fixed on the positioning core axle lower end, the upper and lower end face angle α of standard ring 9 and interior hole depth h are consistent with measured hole two ends angle α and measured hole depth standard value h on the tested part 6, and standard ring endoporus aperture is consistent with locating sleeve 8 external diameters.During measurement, earlier standard ring is placed on the flat board, the locating sleeve of survey instrument is put into the standard ring endoporus, the end face A of positioning core axle contacts with standard ring end face B, and the contact of sounding rod head is dull and stereotyped, dial gauge is adjusted to zero-bit, and dial gauge is clamped; Again survey instrument is inserted tested part, with the positioning core axle location, mandrel end face A contacts with the measured hole upper surface, and this moment, surface readings was the poor of hole depth and standard value, and this difference adds that standard value is the measured hole actual grade.
