Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the entity structure synoptic diagram of an embodiment of the present invention;
Fig. 2 is a housing parts cut-open view embodiment illustrated in fig. 1;
Fig. 3 contacts the situation synoptic diagram for measuring rod in using with taper hole.
Embodiment
The structural representation of an embodiment of the present invention shown in Fig. 1 to 2, the taper hole detector, comprise detection head assembly that contacts with taper hole 8 and the dial gauge 1 that is located at detection head assembly top reading of data, described detection head assembly comprises shell 2, be provided with inner chamber 21 in the shell, be provided with the measurement rod 3 that slides up and down along internal chamber wall in the inner chamber, the top of shell is provided with through hole I22, the bottom of shell is provided with through hole II23, the upper end of measuring rod is installed among the through hole I, the thimble of dial gauge is pressed on the upper surface 31 of measuring rod, the lower end of measuring rod passes among the through hole II and contacts with taper hole, measure rod and be provided with elastic construction and will measure rod and push away downwards, be provided with the screens structure between the rod and prevent to measure excellent with measuring by elastic construction release inner chamber at inner chamber; Elastic construction comprise be located at measure the step I32 on the rod and be enclosed within step I and inner chamber upper surface 211 between compression spring 4; Described shell comprises upper casing 201 and the lower casing 202 that is threaded, the internal chamber wall of upper casing is provided with internal thread 24, the lateral wall of lower casing is provided with the external thread 25 with screw-internal thread fit, and described screens structure comprises being located to be measured the step II33 on the rod and be located on the internal chamber wall in the lower casing step III26 with step II screens.Be provided with contiguous block 5 between shell and the dial gauge, contiguous block top is provided with projection 51, vertically is provided with through hole III52 in the projection, and the thimble of dial gauge passes through hole III and is pressed on the upper surface of measuring rod, laterally is provided with the housing screw 6 of locking thimble on the projection.
As shown in Figure 3, measure the equal diameters of a certain degree of depth of required detection in the diameter of excellent lower surface 34 and the taper hole.The diameter of shell bottom face 27 surpasses the maximum gauge of taper hole.When adopting the present invention to detect the degree of depth at a certain diameter place in the taper hole, before the measurement, unclamp housing screw earlier, detect whether operate as normal of dial gauge; On horizontal table, will measure excellent lower surface then and the shell bottom face is adjusted to same plane, dial gauge will be made zero; After making zero, excellent lower end be will measure and shell bottom face and taper hole place planes overlapping in the taper hole to be measured vertically probeed into, measure rod under the effect of compression spring, measure excellent lower surface and understand the diameter cooperation of a certain depth H that the client requires on automatic and the taper hole, the desired depth H of client can read out on dial gauge easily like this.
