Description

Micrometer
Technical Field
The utility model relates to a mechanical measuring tool technical field especially relates to a micrometer.
Background
The micrometer screw, also known as micrometer, micrometer screw, micrometer caliper, micrometer caliper are more precise length measuring tools than vernier calipers, and can measure length to 0.01mm accurately, with a measuring range of several centimeters. A part of the screw is processed into a thread with the thread pitch of 0.5mm, when the screw rotates in a thread sleeve of a fixed sleeve B, the screw advances or retreats, a movable sleeve C and a screw rod are connected into a whole, and the periphery of the screw is equally divided into 50 grids. The whole circle number of the screw rod rotation is measured by the scribed lines on the fixed sleeve at intervals of 0.5mm, the part less than one circle is measured by the scribed lines on the periphery of the movable sleeve, and the final measurement result needs to be estimated and read by one decimal.
However, there are errors in the micrometer measurement, and the error source is mainly manual error, for example, when measuring a fine component, because the holding angle of the component is slightly changed or the holding angle of the micrometer is slightly changed, the measurement results will be different from each other, and errors are generated, in a certain sense, the measurement precision is not dependent on the estimation of the measurement error, but depends on the quality of the measurement method and the measurement condition; to improve the measurement accuracy, a scientific measurement method and good measurement conditions must be adopted.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that exists among the above-mentioned prior art, provide a micrometer for in the measurement process, utilize V type groove to provide the support for the part to be measured, guarantee that the part to be measured remains stable in the measurement process, reduces the error.
In order to achieve the above object, the utility model provides a following technical scheme:
a micrometer, comprising: ruler frame, measuring head, micrometer screw, locking device, sleeve pipe, sleeve, afterbody knob, the micrometer still includes: spiral fixed establishment and anti-skidding structure, spiral fixed establishment includes:
the base and the connecting rod are integrally formed, and the upper part of the connecting rod is fixedly connected with the screw rod; a through hole is formed in the bottom of the ruler frame, and internal threads are arranged in the through hole and matched with the screw rod for use;
the top of the screw rod is fixedly connected with a supporting block, and the upper surface of the supporting block is provided with a V-shaped groove;
the surface of the ruler frame is provided with an anti-skid structure.
Further, the anti-slip structure is a plurality of protruding structures, and the protruding structures can be arranged regularly or irregularly.
The utility model has the advantages that:
the utility model provides a micrometer, which is used for rotating a supporting block to a proper height through a screw rod in the measuring process, and simultaneously providing support for a part to be measured through a V-shaped groove, ensuring that the part to be measured keeps stable in the measuring process, and reducing errors; meanwhile, the stability of the micrometer in the measuring process can be ensured through the base support; the branch ruler is convenient and easy to carry, and has strong practicability.
