Description

Technical Field

[0001] This utility model relates to the field of measurement, and in particular to a special measuring tool for internal and external diameters. Background Technology

[0002] In the field of machining, with industrial development, it is often necessary to precisely machine the inner and outer diameters of some parts. Furthermore, with the continuous development of industrial manufacturing technology, the accuracy requirements for the inner and outer diameters of parts are becoming increasingly stringent, and accurate measurement is crucial for ensuring product quality and performance. Traditional methods for measuring inner and outer diameters often rely on large measuring equipment, such as coordinate measuring machines (CMMs) and projectors. While these devices offer high precision, they are bulky, complex to operate, difficult to carry, and require professional maintenance and operation, thus failing to meet the needs of rapid on-site measurement. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a portable internal and external diameter measuring tool with a simple overall structure, capable of measuring the internal and external diameters of parts, easy and uncomplicated operation, and improved usability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A special measuring tool for internal and external diameters includes a handle, with a limit block fixedly connected to the upper end of the handle; a rotating block is connected to the lower end of the handle; and a micrometer is fixed on the rotating block.

[0005] Preferably, the rotating block has fastening bolts for fixing.

[0006] Preferably, the micrometer has a spring probe at its front end.

[0007] Preferably, the lower end of the handle has a fastening bolt for tightening the rotating block. Preferably, the rotating block can be rotated to adjust the orientation of the micrometer. Compared with the prior art, the beneficial effects of this utility model are: it can accurately measure the inner and outer diameters of parts, improve the processing accuracy of parts, expand the application range, facilitate use, improve the production efficiency of parts, is safe and reliable, easy to operate, and has a simple overall structure, which facilitates manufacturing and production, reduces production and use costs, and increases economic benefits.

[0008] Furthermore, this special measuring tool for internal and external diameters can be used in various environments, including factory production workshops and outdoor work sites. It not only makes it convenient for operators to use, but also expands the application range of this special measuring tool for internal and external diameters, making it easier to use.

[0009] In addition, this special measuring tool for internal and external diameters has good stability and durability, and the handle is made of wear-resistant material, which improves the service life of the measuring tool. Attached Figure Description

[0011] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0012] Please refer to the reference. Figure 1 An embodiment of this utility model provides a special measuring tool for internal and external diameters, including a handle 1. A limiting block 3 is fixedly connected to the upper end of the handle 1. A rotating block 2 is connected to the lower end of the handle. A micrometer 4 is fixed on the rotating block 2. A fixing bolt 5 is provided on the rotating block 2 for fixing. A spring probe 41 is provided at the front end of the micrometer 4. A fastening bolt 6 is provided at the lower end of the handle 1 for fastening the rotating block. The rotating block 2 can be rotated to adjust the orientation of the micrometer 4.

[0013] During measurement, the measuring instrument handle 1 is placed upside down on the part being measured, and the measuring instrument is limited by the limiting block 3. At this point, the position of the measuring instrument is determined, thus adapting to the measurement requirements. The striker 41 of the micrometer 4 then contacts the inner or outer diameter of the part, triggering deformation and generating a reading, which is easily read and recorded by the measuring personnel. Simultaneously, the measuring personnel can rotate the entire measuring instrument using the handle to further verify the consistency of the inner and outer diameters of the part. After measurement, the limiting block 3 is removed from the edge of the part, and the measuring instrument is taken out. The deformation of the spring striker 41 is unloaded, and the measuring instrument returns to its original position, ready for the next measurement. Furthermore, to handle various measurement situations, the measuring personnel can adjust the direction of the rotating block 2 by adjusting the fastening bolt 6 to switch between inner and outer diameter measurement modes, thus adapting to the measurement needs of more parts.

[0014] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
