Description
Technical field
The utility model belongs to outside micrometer frock technical field, is specifically related to the two measuring surface outside micrometer stiff end measuring head of a kind of stepped ramp type.
Background technology
In current outside micrometer, the title of stiff end measuring stick has; Stiff end measuring head, claw etc.; The form of outside micrometer stiff end measuring stick has two kinds: a kind of measuring stick for cylindrical structure form: its measuring surface is less, precision is very high, energy precise engineering surveying excircle of workpiece size, and it is convenient to correct, but, the excircle dimension of threads of lead screw and worm screw tooth top class workpiece can not be measured; Another kind is the measuring stick of T-type structure form: its measuring surface is comparatively large, and precision is general, can measure general precision excircle of workpiece size, can measure again the excircle dimension of threads of lead screw and worm screw tooth top class workpiece, corrects inconvenient.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of stepped ramp type two measuring surface outside micrometer stiff end measuring head, break the version of existing stiff end measuring head, can precise engineering surveying optical axis excircle dimension, the excircle dimension of threads of lead screw and worm screw tooth top class workpiece can be measured again.
In order to achieve the above object, the utility model comprises the C type frame in arc-shaped, the two ends of C type frame offer through hole in opposite directions, the milscale pointing to other end through hole is provided with in the through hole of C type frame one end, stepped ramp type amount head is provided with in the through hole of the other end, stepped ramp type amount head comprises and is arranged in through hole and stretches out the right cylinder that through hole points to milscale, and be coaxially arranged with annular platform outside right cylinder, right cylinder stretches out annular platform.
The circular arc of described C type frame is 180 °.
Described stepped ramp type measuring head and milscale all point to the center of circle of C type frame.
Compared with prior art, the utility model has stepped ramp type amount head, stepped ramp type amount head has the advantage of column type measuring head and T-shaped measuring head, can precise engineering surveying optical axis excircle dimension, the excircle dimension of threads of lead screw and worm screw tooth top class workpiece can be measured again, metering system is various, has the advantages that a chi is multiplex.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the contrast schematic diagram that the measuring stick of the utility model and existing cylindrical structure form measures optical axis;
Fig. 3 is the contrast schematic diagram that the measuring stick of the utility model and existing T-type structure form measures threads of lead screw and worm screw tooth top cylindrical.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1, the utility model comprises the C type frame 1 in 180 ° of arc-shapeds, the two ends of C type frame 1 offer through hole in opposite directions, the milscale 3 pointing to other end through hole is provided with in the through hole of C type frame 1 one end, be provided with stepped ramp type amount 2 in the through hole of the other end, stepped ramp type measuring head 2 and milscale 3 all point to the center of circle of C type frame 1, and stepped ramp type amount 2 comprises and is arranged in through hole and stretches out the right cylinder of through hole sensing milscale 3, be coaxially arranged with annular platform outside right cylinder, right cylinder stretches out annular platform.
See Fig. 2, when the utility model measures optical axis time, a stepped ramp type amount right cylinder of 2 is contacted with the axial plane of optical axis, contact with optical axis axial plane by rotating milscale 3, thus measure the diameter of axle.
See Fig. 3, when the utility model measures threads of lead screw and worm screw tooth top cylindrical time, make the annular platform of stepped ramp type amount 2 and threads of lead screw and worm tooth top contact, right cylinder stretches in teeth groove, by rotating milscale 3 and peak contact, thus measure tooth top outside diameter.
