Embodiment Construction

[0012] The purpose of the present invention is mainly to provide a kind of accurate measuring device for the tensile strength measurement of the welding joint of micro-workpieces in resistance welding microscopic welding, its measuring range is generally below 2 kilograms, and the measuring accuracy reaches ± 1g. At the same time, the present invention is also applicable to measuring the tensile strength of various small objects, such as the measurement of the adhesive force of the small-area bonding surface of viscose, and the tensile strength measurement of various thin metal wires, small metal strips or fine enameled wires. Strength is measured. Therefore, the present invention can also be referred to as a micro tension measuring instrument for short.

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] refer to Figure 1-3 , according to one embodiment of the present invention, a micro-weld...

Abstract

The invention relates to a microscopic welding micro-tensile measuring instrument, which comprises a base, a support column arranged on the base, a frame arranged on the top of the support column, a workpiece chuck capable of moving up and down relative to the frame and a workbench which is arranged on the base and corresponds to the workpiece chuck, wherein a tension conducting structure with a pull rod is arranged in the frame; the pull rod extends out of the bottom of the frame and is fixed with the workpiece chuck; and a tension sensor is arranged inside the workpiece chuck, and is electrically connected with a tension display device. In the microscopic welding micro-tensile measuring instrument, the new photoelectric technology and mechanical technology of the tension sensor are combined, so that the tension sensor becomes a new measuring instrument which combines optics, mechanics and electronics; and the tension sensor is arranged on the workpiece chuck, so that the friction and various resistances which are caused by driving the workpiece chuck to move up and down are prevented, the measuring accuracy of tension is improved, and the measurement on the tension of small workpieces is realized.

Description

【Technical field】 [0001] The invention relates to a small-scale tension measuring device, in particular to a micro tension measuring instrument for measuring the tensile strength of welding joints of fine workpieces in micro welding. 【technical background】 [0002] In the field of resistance welding micro-welding technology, it is often necessary to detect the welding firmness of micro-workpieces. This detection is usually achieved by measuring the tensile force of the welded joint. The industry requires that the precision of the welding tensile force of micro-workpieces should be measured in grams, and the measuring range is generally about several hundred grams. However, for a long time, there has been no tension measuring instrument with such a small measurement range in the field of resistance welding micro-welding technology. [0003] On the contrary, the measurement range of the existing tension measuring instrument is often more than tens of kilograms or even hundre...
