Abstract
The utility model discloses a kind of micrometer with spiral gage button, including arch chi frame, fixes sleeve, microdrum, ratchet device for measuring force, micrometric screw；Also include spiral gage button, spiral gage button is cylindrical thread screw, the through hole of spiral gage button external diameter is just equal to along micrometric screw axis direction provided with aperture to one end of micrometric screw on arch chi frame, through-hole inner surface is provided with the internal thread being engaged with spiral gage button screw thread, and spiral gage button is connected with through hole by screw thread rotation.The utility model is simple in construction, and available for the improvement of existing micrometer, convenient use person's operation is conducive to the quickly calibrated of micrometer zero point, improves measurement efficiency and accuracy.
Description
Technical field
The utility model is related to a kind of dimensional measuring instrument, specially a kind of micrometer with spiral gage button.
Background technology
Micrometer is a kind of length measuring instrument of more precision.The micrometer calibrated, when micrometric screw connects with gage button
When touching, differential sleeve should align with the zero graduation line in fixes sleeve.It will be produced if do not alignd, during measurement and be
System error.Now need to carry out micrometer zero point correction with specific purpose tool, or write down the zero reading of micrometer, then will
The reading measured every time subtracts zero reading and is only actual measurement result, is thus made troubles to user.
The content of the invention
The purpose of this utility model, is the disadvantages mentioned above for overcoming existing micrometer, develops a kind of thousand points with spiral gage button
Chi.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：It is a kind of with spiral gage button
Micrometer, including arch chi frame, fixes sleeve, microdrum, ratchet device for measuring force, micrometric screw；Also include spiral gage button, it is described
Spiral gage button is that just one end of micrometric screw is set along micrometric screw axis direction on cylindrical thread screw, the arch chi frame
There is through hole, the aperture of the through hole is equal to the external diameter of spiral gage button, and through-hole inner surface is provided with what is be engaged with spiral gage button screw thread
Internal thread, spiral gage button is connected with through hole by screw thread rotation, and the length of spiral gage button is more than the length of through hole.
The pitch of the spiral gage button is 0.5mm, to coordinate the pitch of micrometric screw, it is ensured that Adjustment precision.
The utility model rotates microdrum before measuring, first makes micrometric screw be in contact with spiral gage button, if now micro-
Divide sleeve not alignd with the zero graduation line in fixes sleeve, spiral gage button can be unclamped, fine setting microdrum makes zero graduation line align,
Slowly rotating screw gage button makes micrometric screw just be contacted with spiral gage button again, thus completes the zero point adjustment of micrometer.This reality
Simple with new structure, available for the improvement of existing micrometer, convenient use person's operation is conducive to the quick school of micrometer zero point
Standard, improves measurement efficiency and accuracy.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is composition schematic diagram of the present utility model.
In figure：1. arch chi frame, 2. fixes sleeves, 3. microdrums, 4. ratchet device for measuring force, 5. micrometric screws, 6. spirals
Gage button, 7. through holes, 8. stop knobs, 9. spring shims.
Embodiment
As shown in figure 1, the utility model includes arch chi frame 1, fixes sleeve 2, microdrum 3, ratchet device for measuring force 4, survey
Micro- screw rod 5, in addition to spiral gage button 6, spiral gage button 6 are cylindrical thread screw.Just to micrometric screw 5 on arch chi frame 1
One end is provided with through hole 7 along the axis direction of micrometric screw 5, and the aperture of through hole 7 is equal to the external diameter of spiral gage button 6, and the inner surface of through hole 7 is set
There is the internal thread that the screw thread with spiral gage button 6 is engaged, spiral gage button 6 is connected with through hole 7 by screw thread rotation, spiral gage button 6
Length be more than through hole 7 length, the head of spiral gage button 6 has been arranged with the spring shim 9 of pressuring action.
The pitch of spiral gage button 6 is identical with the pitch of micrometric screw 5, is 0.5mm.
The upper end vertical through hole 7 of arch chi frame 1 is provided with stop knob 8, for further fixing spiral gage button after zero point adjustment
6, prevent it from loosening.
A kind of adjustable solenoid of unit length coil turn.
