Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing detection, in particular to a circular electronic measuring tool. Background Art

[0002] Most of the existing gauges for measuring wall thickness are square structures. It is necessary to increase the length of the gauge to increase the measuring range of wall thickness, resulting in a long gauge but a small measuring range. Although the existing gauge can measure thickness, the measuring range of wall thickness is limited, and the opening and closing angle is small. For some special-shaped parts, the target thickness cannot be measured due to the small measuring opening and closing angle.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN 209673010 U discloses a thickness gauge for castings, including a contact plate and a clamping plate; the contact plate includes a contact portion, a connecting portion and a measuring portion connected in sequence, the contact portion is used to fit with the first side wall of the workpiece, and the measuring portion is provided with a numbering slot; the clamping plate includes a rotating portion and a clamping portion connected to each other, the clamping portion is used to fit with the second side wall of the workpiece, the rotating portion is provided with an indicating line slot, the rotating portion is rotatably connected to the connecting portion to drive the clamping portion to approach or move away from the contact portion; in the initial state, the indicating line slot is aligned with the starting number of the indicating slot, and when the contact portion and the clamping portion are in contact with the first side wall and the second side wall respectively, the indicating line slot is aligned with the other numbers of the indicating slot, and the staff can obtain the distance between the first side wall and the second side wall by reading the number pointed to by the indicating line slot, and the whole operation is simple and convenient, and the obtained result is accurate. However, this gauge cannot measure special-shaped parts.

[0004] Another example is the Chinese utility model patent with the authorization announcement number CN 219607910 U, which discloses a thickness gauge, including a clamping plate, a contact plate and an auxiliary mechanism, the auxiliary mechanism including two sliders, an auxiliary plate and a clamping assembly, the two sliders are fixedly connected to the auxiliary plate, the auxiliary plate is twitchingly connected to the measuring part, and the two sliders are also slidably connected to the measuring part, the clamping assembly is fixedly connected to the measuring part and penetrates the measuring part, and the clamping assembly is also clamped to the auxiliary plate. By setting a scale on the auxiliary plate and then twitchingly connecting the auxiliary plate to the measuring part, the problem of the scale of the measuring part not being too long, otherwise it will affect the placement space of the gauge, but the gauge still cannot measure special-shaped parts. Summary of the invention

[0005] In order to solve the above technical defects in the prior art, the purpose of the utility model is to provide a circular electronic measuring fixture, which can detect angles and directly convert angle data into required dimensional data by designing the main structure part as a circular structure and adding an electronic display.

[0006] In order to solve the above technical problems, the solution adopted by the utility model is as follows:

[0007] The utility model provides a circular electronic measuring tool. The tool body is a retractable structure, which comprises a retractable frame, a circular keel frame and an electronic display screen located on the circular keel frame. The size of the measured part can be quickly read through the electronic display screen.

[0008] Preferably, the retractable frame is located in the circular keel frame, and the retractable frame can be retracted in the circular keel frame, so that the gauge can achieve a larger opening and closing angle, and is suitable for measuring parts with high legs and thin bottoms.

[0009] In any of the above schemes, preferably, the ends of the telescopic frame and the circular keel frame are both provided with circular ejectors, and the circular ejectors are provided to make the contact between the gauge and the measured part point contact, thereby reducing friction on the measured part.

[0010] In any of the above solutions, preferably, the electronic display screen includes a computing chip, a battery and a sensing element, the sensing element senses the opening and closing angle of the inspection fixture, and the chip converts the angle data into required size data.

[0011] In summary, the circular electronic measuring fixture of the utility model has the following advantages: by designing the entire fixture into a circular structure, the opening and closing angle is large, and the measuring range is enlarged, so that parts with high legs and thin bottoms can be measured; the electronic display screen on the circular keel frame can quickly read the size of the measured part through the electronic display screen.
