Abstract
The invention discloses a kind of micrometer caliper for facilitating zero point correction, 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, one end on arch chi frame just to micrometric screw is provided with through hole of the aperture equal to spiral gage button external diameter along micrometric screw axis direction, 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.Simple structure of the present invention, convenient use person's operation, is conducive to the quick zero point correction of micrometer caliper, improves measurement efficiency and accuracy.
Description
Technical field
The present invention relates to a kind of dimensional measuring instrument, specially a kind of micrometer caliper for facilitating zero point correction.
Background technology
Micrometer caliper is a kind of more accurate length measuring instrument.The micrometer caliper calibrated, works as micrometric screw
When being contacted with gage button, differential sleeve should align with the zero graduation line in fixes sleeve.If do not alignd, during measurement just
Can generation system error.Now need to carry out zero point correction to micrometer caliper with specific purpose tool, or write down micrometer caliper
Zero reading, the reading of each measurement is then subtracted into zero reading and is only actual measurement result, thus to user with
It is inconvenient to come.
The content of the invention
The purpose of the present invention, is the disadvantages mentioned above for overcoming existing micrometer caliper, develops a kind of spiral shell for facilitating zero point correction
Rotation mircrometer gauge.
In order to solve the above-mentioned technical problem, the present invention is achieved through the following technical solutions：Including arch chi frame, fixed cover
Cylinder, microdrum, ratchet device for measuring force, micrometric screw；Also include spiral gage button, the spiral gage button is cylindrical thread screw；
One end on the arch chi frame just to micrometric screw is provided with through hole along micrometric screw axis direction, and the aperture of the through hole is equal to
The external diameter of spiral gage button, through-hole inner surface is provided with the internal thread being engaged with spiral gage button screw thread, and spiral gage button passes through with through hole
Screw thread rotation is connected, the length of the length more than through hole of spiral gage button.
The pitch of the spiral gage button is 0.5mm, and the pitch with micrometric screw is identical, to ensure Adjustment precision.
The present invention rotates microdrum before measuring, first makes micrometric screw be in contact with spiral gage button, if now differential set
Cylinder does not align with the zero graduation line in fixes sleeve, can unclamp spiral gage button, and fine setting microdrum makes zero graduation line align, then slowly
Slow rotating screw gage button makes micrometric screw just be contacted with spiral gage button, thus completes the zero point correction of micrometer caliper.This hair
Bright simple structure, can be used for the improvement of existing micrometer caliper, and convenient use person's operation is conducive to quick the zero of micrometer caliper
Point calibration, improves measurement efficiency and accuracy.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is composition schematic diagram of the invention.
In figure：1. arch chi frame, 2. fixes sleeve, 3. microdrum, 4. ratchet device for measuring force, 5. micrometric screw, 6. spiral
Gage button, 7. through hole, 8. stop knob, 9. spring shim.
Specific embodiment
As shown in figure 1, the present invention includes arch chi frame 1, fixes sleeve 2, microdrum 3, ratchet device for measuring force 4, micrometer spiral shell
Bar 5, also including spiral gage button 6, spiral gage button 6 is cylindrical thread screw.Just to one end of micrometric screw 5 on arch chi frame 1
Be provided with through hole 7 along the axis direction of micrometric screw 5, the aperture of through hole 7 is equal to the external diameter of spiral gage button 6, the inner surface of through hole 7 be provided with
The internal thread that the screw thread of spiral gage button 6 is engaged, spiral gage button 6 is connected with through hole 7 by screw thread rotation, the length of spiral gage button 6
Degree is more than the length of through hole 7, and 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 correction
6, prevent it from loosening.
