Abstract
The utility model discloses a metric/imperial outside diameter micrometer, which can simultaneously provide metric and imperial measurement results, has a simple structure and is convenient to use. The metric/imperial outside diameter micrometer comprises a scale holder, a micrometer head and a counter, wherein the micrometer head and the counter are arranged on the scale holder, are connected together through a gear arranged on a gear shaft sleeve and are respectively provided with metric scales and imperial scales.
Description
Technical field
The utility model relates to a kind of metric and English outside micrometer.
Background technology
Outside micrometer is the accurate testing tool of a kind of outside dimension commonly used in the machining.Existing metric system outside micrometer can only partly be read metric system numerical value at micrometer head, and existing outside micrometer made in Great Britain can only partly be read numerical value made in Great Britain at micrometer head.Though for existing counter outside micrometer micrometer head sum counter two cover frames of reference are arranged, also can only show the metric system reading synchronously or show reading made in Great Britain synchronously.
The utility model content
The purpose of this utility model is the deficiency that exists at above-mentioned prior art, and a kind of metric and English outside micrometer is provided.This metric and English outside micrometer can read public affairs, two kinds of measurement results made in Great Britain simultaneously, and is rational in infrastructure, easy to use.
The technical solution of the utility model comprises the chi frame, be located at micrometer head, the sum counter of the micrometric screw formation that is arranged with gear bush comprising on the chi frame, described micrometer head sum counter interconnects by the gear of being located on the gear bush, and described micrometer head sum counter is respectively equipped with metric system and read text scale made in Great Britain.
Described micrometric screw is provided with spiral guide slot, and described gear bush is connected with micrometric screw by a holding screw.
The spiral guide slot of being located on the described micrometric screw is a V-type spiral guide slot, and described holding screw is corresponding awl end holding screw, and gear bush is connected with micrometric screw by this awl end holding screw.
The helix angle of described spiral guide slot or awl end spiral guide slot is 11 minutes left-handed or right hand helixs of 2 degree.
Described counter is located in the square opening on the chi frame corresponding to an end of micrometric screw; Be respectively equipped with heat-proof device on the described chi frame and corresponding to the clamping device of gear bush; The opposite end of described gear bush respectively and be provided with flat shim and elastomeric pad between the corresponding site of chi frame.
The metric and English outside micrometer of utility model adopts micrometer head sum counter two cover frames of reference, micrometer head partly shows metric system numerical value, counter portion shows numerical value made in Great Britain, the absolute growth of the numerical value that two cover frames of reference are read equates, can read public affairs, two kinds of measurement results made in Great Britain simultaneously, simple in structure, compact, reasonable in design, processing and use are simple, convenient.
Description of drawings
Fig. 1 is the utility model structural representation.Fig. 2 is the counter structure synoptic diagram among Fig. 1.Fig. 3 is the structural representation of the micrometric screw among Fig. 2.
Embodiment
Now also the utility model is described in further detail in conjunction with the accompanying drawings by embodiment.
As Fig. 1, Fig. 2 and shown in Figure 3, chi frame 1 is provided with a square cavity, and counter 3 and other corresponding drive disk assembly just are installed in square cavity.Micrometric screw 10 is provided with the V-type spiral guide slot, the gear bush 8 that is arranged in square cavity is sleeved on and leans on square cavity one end on the micrometric screw 10, is connected with micrometric screw 10 by V-type spiral guide slot 12 by the tapered awl end holding screw 7 of an end, and gear bush 8 can be rotated with micrometric screw 10; Read text scale made in Great Britain is located on the counter 3, and corresponding metric system read text scale is located on the micrometer head 2.
The awl end of awl end holding screw 7 inserts in the V-type spiral guide slot of micrometric screw 10, can not have the gap along the V-type spiral guide slot and slide when micrometric screw 10 rotates.
Gear 9 is fixed on the gear bush 8, directly meshes with transmission gear on the counter 3, and counter 3 is together rotated with micrometer head 2.
Gear ratio and actual required ratio of gear according to the transmission gear on gear 9 and the counter 3 compare, it is 11 minutes left-handed spirals of 2 degree that the V-type spiral guide slot 12 of micrometric screw 10 is processed into helix angle 12a, in order to the ratio of gear difference of backoff counter 3 with micrometric screw 10.
At the opposite end of gear bush 8 respectively and be provided with flat shim 6 and elastomeric pad 11 between the corresponding site of chi frame.Flat shim 6 and elastomeric pad 11 can guarantee that gear bush 8 does not have axial float when rotating on micrometric screw 10.
Counter 3 and transparent counter cover plate respectively by screw retention on chi frame 1.
Screw as clamping device 4 can act directly on the gear bush 8 by chi frame 1, can unclamp or prevent the rotation of micrometric screw 10.Heat-proof device 5 can prevent that operating personnel's body temperature from influencing measuring accuracy to chi body conduction heat.
