Description

Technical Field

[0001] The invention relates to the technical field of copper tube measurement, in particular to a thin copper tube softness measuring instrument. Background Art

[0002] Thin copper tubes are widely used in the manufacture of conductive and heat-conducting equipment due to their good electrical and thermal conductivity. Therefore, thin copper tubes are often used in heat exchange tubes. As the temperature changes, the heat exchange tubes will expand or contract, and the heat exchange tubes are generally in a fixed state. When the heat exchange tubes expand or contract, it is easy to exert force on the structure fixed to it. After long-term use, it is easy to affect the structure fixed to it. Therefore, the softness of thin copper tubes should be tested during production. Summary of the invention

[0003] The technical problem solved by the present invention is to provide a thin copper tube softness measuring instrument to solve the problems in the above-mentioned background technology.

[0004] The technical problem solved by the present invention is achieved by adopting the following technical solutions: A thin copper tube softness measuring instrument comprises an upper handle, a lower handle, a main body, a linkage handle, a dial, a pressure needle, a support plate, an adjustment disk, a clamping block and a connecting disk, wherein the upper handle and the lower handle are respectively installed on the main body to form an arc-shaped clamping structure when working, a clamping block is arranged on the inner side of the main body, one end of the clamping block is connected to the upper handle, and the other end of the clamping block is connected to the dial through the connecting disk, and an adjustment disk for adjusting the softness is arranged on the clamping block, a linkage handle for assisting in clamping the dial is arranged above the dial, a pressure needle is arranged on the main body below the dial, and a support plate for placing a thin copper tube for measurement is arranged below the pressure needle.

[0005] In the present invention, the clamping block is an arc-shaped structure.

[0006] In the present invention, a gasket is provided on the linkage handle to protect the dial.

[0007] In the present invention, a spring is arranged inside the pressing needle, and the pressing needle is driven to move up and down by the elastic force of the spring.

[0008] In the present invention, a self-calibration component is provided on the dial. When the dial is used for a period of time, the scale is calibrated by the self-calibration component. Before preparing for calibration, the required standard sample or copper tube of known softness is selected to evaluate the difference between the measurement result and the known value, and judge the accuracy of the measuring instrument. If the difference is large, the measuring instrument needs to be calibrated or adjusted and re-verified.

[0009] In the present invention, the adjusting disk is arranged above the connecting disk, and the softness of the softness measuring instrument is adjusted by the adjusting disk.

[0010] In the present invention, when in use, first place the thin copper tube to be measured on the support plate, then press the upper handle and the lower handle to form an arc-shaped clamping structure, observe and record the scale on the dial at this time, and then loosen the upper handle and the lower handle.

[0011] Beneficial effects: The present invention measures the softness of a thin copper tube by pressing the upper handle and the lower handle, which is simple and convenient. At the same time, a self-calibration component is provided on the dial. When the dial is used for a period of time, the scale is calibrated by the self-calibration component, which effectively reduces the measurement error. BRIEF DESCRIPTION OF THE DRAWINGS
