Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 2-Fig. 7, a kind of gauge detecting barrel rifle internal diameter, as shown in Figure 1, the barrel endoporus 7 of the barrel 6 detected, this gauge includes that this poker 1 can pass freely through surveyed barrel endoporus 7 in cylindrical poker 1, poker 1 is made up of the scale section 12 of handling section 11, ladder section 13 and connection handling section 11 and ladder section 13, scale section 12 on poker is carved with scale vertically, optimization, and the scale minimum scale of the scale section 12 on described poker is 0.5mm～2mm.Ladder section 13 on poker is provided with threaded interior hole 14, and this threaded interior hole 14 axially extends to the scale section 12 on poker, and threaded interior hole 14 female thread on described poker connects conversion cone 4.Described conversion cone 4 is cylindrical, threaded with described poker 1 in conversion cone 4 one end, socket measurement 3 on the other end of conversion cone 4, conversion cone 4 socket measures the diameter of 3 sections less than this end end diameter of this conversion cone 4, and conversion cone 4 socket is measured a 3 end end diameter and is used for positioning measurement 3 less than barrel endoporus to be measured.The described outer peripheral face changing cone 4 socket measurement 3 end is taper seat, and changing the tapering of taper seat in cone 4 is α1=0 ° of 10 ＇～15 °.In a tubular form, the inner peripheral surface of measurement 3 is also that taper seat coordinates with the outer peripheral face of described conversion cone 4 in described measurement 3, and the tapering of the taper seat in measurement 3 is α2=0 ° of 10 ＇～15 °.Described measurement 3 tube wall offers an opening 31 vertically, and opening 31 is measured 3 and axially disconnected and enable the radial dimension of measurement 3 to have certain elasticity radially to become big and reinstatement under the active force of conversion cone 4.
The diameter of the ladder section 13 on described poker is less than the diameter of described scale section 12, and sheathed return spring 2 in this ladder section 13, described return spring 2 is stage clip.One end of return spring 2 is inconsistent with the shaft shoulder on poker 1, and the other end of return spring 2 is inconsistent with the end face of described measurement 3.During measurement, elastic force on return spring 2 acts on measurement 3, measurement 3 is made to interact with conversion cone 4, measurement 3 is promoted to open and make the outer peripheral face moment of measurement 3 contact with tested barrel bore area, diametric inner diameter values is changed into the length value on axial with measuring a drive mechanism of 3 compositions by certain gear ratio by conversion cone 4, then reflects testing result with the indicating value of the scale on poker 1.For convenience gauge is exerted a force, the handling section 11 on described poker is carved with reticulate pattern.Described poker 1, return spring 2, measurement 3 and the measurement assembly of conversion cone 4 composition.Also including two master rings 5, the check and correction size of two master rings 5 is respectively maximum and the minima of the barrel rifle internal diameter size that product figure specifies.
During with this gauge detection workpiece (i.e. barrel rifle internal diameter), first should determine that barrel internal diameter is reflected in poker 1 high scale ultimate value with master ring 5 check and correction, i.e. when measuring assembly by master ring 5, changing value according to poker 1 high scale determines its extreme point measured, if the extreme point measured meets requirement, the most again with measuring component detection barrel rifle internal diameter.As shown in Figure 8, when specifically detecting, return spring 2 is first allowed to be in compressive state, now, the measuring point external diameter of measurement 3 is in minimum state, the measurement 3 measured on assembly is inserted in the barrel endoporus 7 of barrels 6, measurement 3 is during slow transitting through barrel endoporus 7, measure a 3 outside diameter value to be limited by barrel endoporus 7 aperture, under the effect of return spring 2 spring force etc., owing to the aperture value of barrel endoporus 7 also exists difference on axis diverse location, measure 3 outside diameter to change along with the difference of barrel endoporus 7 aperture value, the changing value of barrel internal diameter then can be reflected by the situation of change of the scale value of the scale section 12 that the rear end face position of measurement 3 is on poker.When measurement 3 is by barrel endoporus 7, when scale value is not less than the maximum proofreaded through ring gauge 5, minimum scale value, show barrel endoporus 7 size in allowed limits, otherwise, barrel endoporus 7 part internal diameter size is overproof, i.e. barrel endoporus 7 presents " drum type (small at both ends and big in the middle) " or " flat type (being small at both ends and big in the middle) " vertically.This gauge ingenious go out use the traditional mechanism measuring head and conversion cone composition the actual size at each for barrel internal diameter position to be specified relative to product by certain gear ratio the variable quantity of dimension limit be converted into the length value on axial, indicate the barrel rifle internal diameter actual size deviation situation relative to product dimension limit by the scale on poker again, thus solve the difficult problem that barrel rifle internal diameter size concordance cannot detect.
