Description
Technical field
The utility model relates to field of machining, aperture measurement device when being specifically related to a kind of bore hole.
Background technology
Bore hole is to forging, and cast out or the further processing of drilling bore hole, bore hole can expand aperture, improves precision, reduces surfaceness, can also correct the deflection of original axially bored line preferably.During bore hole, knife bar is just needing dress, can not be crooked, breaks machined surface to prevent knife bar.Further, in the process of bore hole, the size measuring aperture is needed to confirm that processed hole reaches dimensional requirement.At present, when measuring aperture, need first to exit boring bar, measure aperture with the length bar being connected to gauge rod again, if aperture does not reach dimensional requirement, need again the processing of centering clamping, in this process, exit boring bar comparatively consuming time, and again centering time cannot the right alignment of definitely twice clamping.
The patent No. 201020233508.3 discloses a kind of size detection milscale of annular endoporus, comprising: backstay, semi-circular chi frame and dial test indicator.Backstay is equipped with in one end of semi-circular chi frame, and one end of backstay is positioned at the outside of semi-circular chi frame outwardly; The dial plate of dial test indicator is fixed on the other end of semi-circular chi frame, and the gauge rod of lever-type micrometer table is positioned at the outside of semi-circular chi frame; On the same line, it is identical that backstay comprises various radius, the screw rod that length is different for the axis of backstay and the axis place of dial test indicator gauge rod; Be applied to the size detection of annular endoporus.But the dial plate of clock gauge is comparatively large, and when the diameter of institute's bore hole is less, the gap between boring bar and hole is less, and clock gauge cannot use.Further, owing to can only regulate with backstay when different size internal diameter is measured in this invention, when the diameter of institute's bore hole is larger, then again need processing semicircular ring chi frame for measuring, at substantial time and increase cost.
Summary of the invention
Aperture measurement device when the technical problems to be solved in the utility model is to provide a kind of bore hole, can measure the internal diameter of institute's bore hole when not needing to exit boring bar.
The utility model is achieved through the following technical solutions:
Aperture measurement device during a kind of bore hole, comprise crescent-shaped bracket, length bar base, length bar, locating bar base, locating bar, the two ends up and down of described crescent-shaped bracket are provided with supported hole, length bar and locating bar are fixed on the two ends up and down of crescent-shaped bracket respectively by length bar base and locating bar base, and described length bar base and locating bar base are rectangle or step.
The further improvement project of the utility model is, the internal diameter of described crescent-shaped bracket is greater than the diameter of boring bar, and external diameter is less than the minimum diameter in the required hole measured.
The utility model further improvement project is, described length bar base is provided with pickup groove, the sidewall of pickup groove is provided with two supported holes, pickup groove is stuck on crescent-shaped bracket, with bolt, length bar base is fixed, the other end of length bar base is provided with length bar fixed orifice, and the side of described pilot hole is provided with clamping slot, and two sidewalls of described clamping slot are provided with tapped through hole.
The utility model further improvement project is, described length bar is placed in length bar fixed orifice, and trip bolt is fixed through tapped through hole locking clamping slot.
The utility model further improvement project is, described locating bar base is identical with the structure of length bar base.
The utility model further improvement project is, when described locating bar is fixed on crescent-shaped bracket by locating bar base, locating bar is coaxial with length bar.
Compared with prior art, tool has the following advantages the utility model:
The utility model structure is simple, when bore hole, the pore size of institute's bore hole directly can be measured when boring bar does not need to exit, avoid again centering clamping and cause twice clamping out-of-alignment problem, and length bar base and locating bar base are rectangle or step, can select to be convenient for measuring according to the aperture of different size.
