Description

A kind of outer diameter micrometer with bracket

【Technical field】

The utility model belongs to the technical field of measuring tools, in particular to an outer diameter micrometer.

【Background technique】

The outer micrometer is composed of a ruler frame, a micrometer head, a locking device, etc. It is a more precise length measuring instrument than a vernier caliper. When using the outer micrometer to measure the length, you need to turn the knob slowly to bring the micrometer head close to the object to be measured. At this time, you need to hold one end of the anvil with one hand, and complete the rotation with the other hand, so that the anvil is aligned with the object to be measured. Object center, when the outer diameter micrometer is large, two people need to cooperate to complete the alignment operation, which not only reduces the measurement speed, but also easily leads to measurement errors.

【Content of utility model】

The purpose of the utility model is to provide an outer micrometer with a bracket, which solves the problems in the prior art.

In order to achieve the above object, the utility model adopts the following technical solutions:

An outer diameter micrometer with a bracket, comprising an outer micrometer and a bracket, the outer micrometer includes a ruler frame, and the bracket includes a plurality of bracket studs with scales and an iron sheet base; a number of steel pipes are arranged on the ruler frame, and the steel pipe is provided with a bracket The studs have the same diameter and threaded holes; the iron sheet base is fixed on the bottom of the corresponding bracket stud; the bracket stud is connected with the corresponding steel pipe thread to support the outer micrometer at the measuring position.

Further, three bracket studs are installed on the ruler frame; the three bracket studs are arranged in an isosceles triangle.

Further, the length of the bracket stud is 10cm, and the scale is marked within the range from the bottom end to 8.5cm. The bottom end of the bracket stud is screwed to fix the iron base with a diameter of 3cm and a thickness of 1cm.

Further, the outer micrometer also includes a lock nut installed on the ruler frame, a measuring rod, a locking device and a micrometer head.

Further, when measuring the workpiece, the iron sheet base is supported on the workbench, and the outer micrometer is suspended in the measuring position through the support of several bracket studs.

Compared with the prior art, the utility model has the following beneficial effects: the utility model has a simple structure and is easy to install, allowing the operator to rotate and fix the circular iron piece on the stud bracket when using a micrometer, and then rotate the bracket to measure In the threaded round hole on the frame, adjust the height of the ruler frame by rotating the bracket and the scale on the bracket. When the measurement work is finished, the iron sheet and the bracket can be rotated and disassembled to facilitate the placement of the micrometer. In this way, the operator can complete the calibration of the outer diameter micrometer by one person, without holding the calibration rod to perform the calibration operation, and avoiding the misalignment phenomenon caused by the operator's hand shaking. Compared with the existing external diameter micrometer, the micrometer of the utility model can improve the measurement speed and reduce the measurement error.

The symbols in the figure represent: 1—lock nut, 2—measuring rod, 3—calibration column, 4—locking device, 5—micrometer head, 6—bracket stud, 7—ruler frame, 8—iron base , 9—steel pipe;

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

【detailed description】

Please refer to Fig. 1 to Fig. 2, a kind of external micrometer with support of the utility model includes an external micrometer and a support, and the external micrometer includes a locking nut 1, a measuring rod 2, a proofreading column 3, and a locking device 4. The micrometer head 5 and the ruler frame 7, the bracket includes a bracket stud 6 with scale and an iron base 8; the steel pipe 9 is located on the ruler frame 7, and the steel pipe 9 has the same diameter as the bracket stud 6 and has threads The hole can make the bracket stud 6 rotate in the hole to adjust the height of the chi frame 7. Three support studs 6 are distributed in an isosceles triangle on the ruler frame 7; the length of the support studs 6 is 10cm, and there are scales marked in the range from the bottom to 8.5cm, and the bottom ends of the support studs 6 utilize threads respectively Fix the iron base 8 with a diameter of 3cm and a thickness of 1cm. The thread depth of the iron base 8 is 0.5cm, and the thread diameter is the same as that of the bracket stud 6. Use the iron base 8 to make the bracket more stable to support the micrometer on the ground.

Working process of the present utility model:

When the support is not in use, the support stud 6 and the iron base 8 are disassembled for storage, which can save storage space; Rotate and fix the bracket studs 6 on the steel pipe 9 of the ruler frame 7, so that the height of the outer micrometer is approximately the same as the height of the measuring point of the test piece. When the height of the outer micrometer is found to be inappropriate, turn the bracket studs 6 one by one. Move the outer micrometer up and down until the height is exactly the same as the measurement point of the specimen, and then the subsequent measurement steps can be carried out.
