Abstract
The utility model relates an external diameter micrometer for cone small head dimensions, possessing an external diameter micrometer body (1), two ends of which are respectively provided with a cylinder probe (4); the two cylinder probes (4) are respectively provided with a spherical positioning device (3); contact surfaces of the spherical positioning devices (3) and the cylinder probes (4) are plane and are located on a same midperpendicular. The external diameter micrometer of the utility model can well guarantee axial positioning of the external diameter micrometer in processes of measuring cone small heads, and can meanwhile be used for measuring dimensions of cone large heads. The measuring is convenient and fast, the operation is simplified and processing efficiency is raised.
Description
Technical field
The utility model relates to a kind of circular cone microcephaly size and uses outside micrometer.
Background technology
The processing that will accomplish circular cone at present must be controlled the angle of circular cone, major part place outside dimension, microcephaly and locate wherein two in these three key elements of outside dimension; The method of routine measurement circular cone is come matching measurement for making the circular cone ring gauge; In the process for large diameter circular cone, this kind metering system is relatively wasted time and energy.And,, cause measuring error very big then because the measuring point screens is inaccurate for measure circular cone microcephaly's outside dimension with common outside micrometer.It is inaccurate finally to influence the circular cone tapering.
The utility model content
The purpose of the utility model is in order to overcome the inaccuracy that circular cone microcephaly size is measured with common outside micrometer, to provide a kind of circular cone microcephaly size simple in structure to use outside micrometer.
The purpose of the utility model realizes as follows: a kind of circular cone microcephaly size is used outside micrometer; Has the outside micrometer body; Respectively there is a cylinder gauge head at the two ends of said outside micrometer body; Said two cylinder gauge heads respectively have spherical locating device, and the surface of contact of said spherical locating device and cylinder gauge head is the plane, and said spherical locating device and said cylinder gauge head are on a perpendicular bisector.
Saying further, the difference of the diameter of said spherical locating device and said cylinder gauge head diameter is a fixed value.
The utility model advantage: the axial location of milscale when adopting this form outside micrometer can well guarantee that the circular cone microcephaly measures.And for circular cone end fixed distance, can well guarantee in the circular cone cutting process control for the circular cone size at the measurement point of circular cone.In addition the milscale of this form can be used as the size of measuring circular cone major part place simultaneously.Convenient measurement is quick, has simplified operation and has improved working (machining) efficiency.The utility model is used in Grinding Process, reaches more than 95% with tapering cubing fitting area behind the finished product.
Description of drawings
For content of the present invention is expressly understood more easily, below according to instantiation, and combine accompanying drawing that the present invention is done further detailed explanation, wherein:
Accompanying drawing is the structural representation of the utility model;
Embodiment:
See accompanying drawing; A kind of circular cone microcephaly size is used outside micrometer, has outside micrometer body 1, and respectively there is a cylinder gauge head 4 at the two ends of said outside micrometer body 1; Said two cylinder gauge heads 4 respectively have spherical locating device 3; Said spherical locating device 3 is the plane with the surface of contact of cylinder gauge head 4, and said spherical locating device 3 and said cylinder gauge head 4 be on a perpendicular bisector, and the difference of the diameter of said spherical locating device 3 and said cylinder gauge head 4 diameters is a fixed value.Its course of work is: see that spherical positioning head device 3 is fixing with outside micrometer body 1, bulb and workpiece 2 end faces are close to, for the measuring outside diameter of microcephaly apart from microcephaly's end face distance carried out in a contact.Measure that the end face be close to needs and the axis normal of circular cone this moment, to guarantee the measuring gained reading and actual value is close.
Above-described instantiation; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the instantiation of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (2)
1. a circular cone microcephaly size is used outside micrometer; Has outside micrometer body (1); It is characterized in that: respectively there is a cylinder gauge head (4) at the two ends of said outside micrometer body (1); Said two cylinder gauge heads (4) respectively have spherical locating device (3), and the surface of contact of said spherical locating device (3) and cylinder gauge head (4) is the plane, and said spherical locating device (3) and said cylinder gauge head (4) are on a perpendicular bisector.
