Abstract
The utility model provides a tool for measuring the inclination of an inclined hole of a housing. The tool comprises a basic body, a guide sleeve, a measuring bar, a dial gauge, a dial gauge bearer, and a standard sample loop with an inner inclined surface. The basic body has a boss, which is higher than the basic body by 1 mm and is used for point attachment with an inclined surface of the inclined hole of the housing. The standard sample loop is removably arranged below the basic body, with an inner inclined hole being closely attached with the boss, for the purpose of zero setting of the dial gauge. When the depth of the inner inclined hole of the standard sample loop is 3 mm, zero setting of the dial gauge is conducted, and the width of a contact point between the measuring bar and the inclined hole of the housing is made to be 0.353 mm. By means of contact between the guide sleeve on the basic body and the inclined hole of the housing at the position with the width of 0.353 mm, the depth position of the inclined surface is measured by the measuring bar. The dimension of the inclination of the inner inclined surface of the standard sample loop is the same as the standard dimension of the inclination of the inclined hole of the housing. In this way, during the measurement, zero setting of the dial gauge is performed first by employing the standard sample loop, then parts are measured, and the inclination of inclined holes of the parts are determined to be qualified or not by observing the difference in readings, which makes easy the complicated measurement of the inclination of the inclined holes.
Description
Technical field
The utility model relates to Machining Technology field, specifically a kind of instrument of measuring inclined hole inclined-plane.
Background technology
Existing technology generally adopts contourgraph to some inclined hole workpiece natural measurement of tilt.For diagram product aperture, have 80 ° ± 0.25 ° inclined-plane of dark 3.65mm to need to measure, the gradient of position, hole is that drawing requirement is controlled.Because inclined hole is shallow, product design is large, and contourgraph is difficult for finding accurately the bus of holes of products when measuring, and the bus in hole is inaccurate, and the data error of measuring can be very large.Such measuring method is consuming time very long, is difficult for measuring accurately, is also not suitable for large batch of need of production.
Utility model content
The utility model object is to provide a kind of improved housing inclined hole gradient measuring tool, can make complicated inclined hole natural measurement of tilt become simple to operation.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is as follows:
A kind of housing inclined hole gradient measuring tool, comprise matrix, orienting sleeve, sounding rod, dial gauge, dial gauge bearing and the standard sample circle with interior inclined-plane, aforementioned substrates has the boss that exceeds matrix 1mm, this boss is for being adjacent to the bevel point of housing inclined hole, aforesaid standards sample circle be arranged on removedly matrix below and in it inclined hole and boss be adjacent to for by dial gauge to zero, aforementioned dial gauge when the interior inclined hole degree of depth of standard sample circle is 3mm to zero and to make the width of the contact point of sounding rod and housing inclined hole be 0.353mm, aforementioned sounding rod contacts the depth location of measuring inclined-plane in the position of width 0.353mm with housing inclined hole by the orienting sleeve on matrix.
Further, the inclination angle on aforesaid standards Yang Quannei inclined-plane is identical with the standard size of housing inclined hole gradient.
Further, the inclination angle on aforesaid standards Yang Quannei inclined-plane is 80 °.
From above the technical solution of the utility model, the beneficial effects of the utility model be to utilize standard sample circle first by dial gauge to zero, dial gauge when in to table sample circle, the inclined hole degree of depth is 3mm to zero, now the width of sounding rod and product inclined hole contact point is 0.353mm, then removing standard sample circle measures the inclined hole inclined-plane of part again, observe its difference of reading, if scope at ± 0.05(by the data that the change in depth during at width 0.353 calculates to 80 ° ± 0.25 ° inclined-plane), be certified products.Can make so complicated inclined hole natural measurement of tilt become simple to operation.

Embodiment
In order more to understand technology contents of the present utility model, especially exemplified by specific embodiment and coordinate appended graphic being described as follows.
As in Figure 2-4, according to preferred embodiment of the present utility model, housing inclined hole gradient measuring tool comprises matrix 1, orienting sleeve 2, sounding rod 3, dial gauge 4, dial gauge bearing 5 and the standard sample circle 6 with interior inclined-plane, standard sample circle 6 is arranged on the below of matrix 1 removedly, matrix 1 has the boss 7 that exceeds matrix 1mm, this boss is for being adjacent to the bevel point of housing inclined hole, standard sample circle 4 be arranged on removedly matrix below and in it inclined hole and boss be adjacent to for by dial gauge to zero, in the present embodiment, as Fig. 3 a and 3b, dial gauge 4 when the interior inclined hole degree of depth of standard sample circle is 3mm to zero and to make sounding rod 3 and the width of the contact point of housing inclined hole be 0.353mm, when measuring housing inclined hole gradient, remove this standard sample circle, sounding rod 3 contacts the depth location of measuring inclined-plane in the position of width 0.353mm with housing inclined hole by the orienting sleeve on matrix.
The inclination angle on standard sample circle 6 interior inclined-planes is identical with the standard size of housing inclined hole gradient.In the present embodiment, with reference to figure 1, the standard size on the inclined-plane of housing inclined hole to be measured is 80 °, and the inclination angle on standard sample Quan Nei inclined-plane is 80 °.
