Abstract
The utility model discloses an utensil is examined to bore depth, which comprises a bracket, the bottom surface of support is the plane, the centre of support is equipped with movable firing pin piece, the below of firing pin piece is fixed and is equipped with long and thin metal rod, the fixed percentage table that is equipped with in the top of firing pin piece on the support, the thimble of percentage table is just to the upper surface of firing pin piece. Utensil is examined to bore depth, its is structural according to product size location, sets up the percentage table through the top at the firing pin piece, the below of firing pin piece sets up the metal rod, the thimble of percentage table is just to the firing pin piece, during the measurement stretches into the metal rod downtheholely, touches the thimble of percentage table through the firing pin block move, observes the relative bore depth of waiting to detect the product through observing the percentage table reading, compares with the standardized product, can judge whether qualified the product is, has improved detection efficiency, has increased the measuring precision.
Description
Technical field
The utility model relates to a kind of cubing, particularly a kind of hole depth cubing.
Background technology
Product with deep hole is measured its hole depth and is mostly adopted kind of calliper at present, but run into aperture less and dark again time, the data of kind of calliper will very large possible generation error, and draw inaccurate data, impact uses.General employing method of substitution is measured, and namely stretch into interiors of products by an elongated metal bar, then mark orifice position, then use length gage measuring, draw hole depth, this method is measured and comparatively bothered, and measuring error is larger.
Utility model content
Utility model object: the purpose of this utility model is to solve above the deficiencies in the prior art, provides a kind of hole depth cubing of Quick Measurement.
Technical scheme: hole depth cubing described in the utility model, its objective is and like this to realize, a kind of hole depth cubing, comprise support, the bottom surface of described support is plane, and the centre of described support is provided with movable firing pin block, and the below of described firing pin block is fixed with elongated metal bar, on described support, the top of firing pin block is fixed with dial gauge, and the thimble of described dial gauge is just to the upper surface of firing pin block.
As optimization, the thimble of described dial gauge, just to the centre of firing pin block, because metal bar tilts slightly when avoiding measuring, causes measurement result to be forbidden.
As optimization, the bottom surface of described metal bar and the angle of sidewall are wedge angle, can not have chamfering, and chamfering can cause the inclination of metal bar, cause measurement result inaccurate.
During detection, measure in advance the standardized element of certain hole depth, then write down the reading of dial gauge, when then detecting part to be measured, whether the reading that only need detect dial gauge, within the scope of permissible error, answers repetitive measurement to average during measurement.
Beneficial effect: hole depth cubing described in the utility model, its structure is located according to product size, by arranging dial gauge above firing pin block, the below of firing pin block arranges metal bar, the thimble of dial gauge is just to firing pin block, during measurement, metal bar is extend in hole, by the thimble of firing pin block moving contact to dial gauge, the relative hole depth of product to be detected is observed by observing dial gauge reading, compared with standardized product, can judge that whether product is qualified, improve detection efficiency, add detection precision.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
Shown in Figure 1, a kind of hole depth cubing, comprise support 1, the bottom surface of described support 1 is plane, the centre of described support 1 is provided with movable firing pin block 2, the below of described firing pin block 2 is fixed with elongated metal bar 3, and on described support 1, the top of firing pin block 2 is fixed with dial gauge 4, and the thimble of described dial gauge 4 is just to the centre position of the upper surface of firing pin block 2.
The bottom surface of described metal bar 3 and the angle of sidewall are wedge angle, and can not have chamfering, chamfering can cause the inclination of metal bar 3, causes measurement result inaccurate.
During detection, measure in advance the standardized element of certain hole depth, then write down dial gauge 4 reading, when then detecting part to be measured, whether the reading that only need detect dial gauge 4, within the scope of permissible error, answers repetitive measurement to average during measurement.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
