A suspended symmetrical single-shaft shoulder temperature measurement and single-dual-shaft universal force measurement device

Abstract

The invention discloses a suspended symmetrical single-shaft shoulder temperature measurement device and a single-dual shaft shoulder general-purpose force-measuring device, which includes an upper platform, a lower platform and a supporting device connecting the upper platform and the lower platform. There is a receiving tank at the bottom of the tank, and a perforated sheet is placed in the receiving tank. The perforated sheet is provided with a first pit, and a temperature measuring backing plate is installed on the first ball in the groove. There is a first sensor accommodating groove, and a first pressure sensor is placed in the first sensor accommodating groove, and a second sensor accommodating groove is provided on the lower platform, and a second pressure sensor is arranged in the second sensor accommodating groove. The suspended symmetrical single-shaft shoulder temperature measurement device and the single-dual shoulder general-purpose force-measuring device of the present invention can not only meet the clamping requirements of the single-dual shoulder friction stir welding technology, but also realize the welding seam in the single-shaft shoulder welding process. Measurement of temperature and three-dimensional force and measurement of travel resistance and lateral force during biaxial shoulder welding.

Description

technical field [0001] The invention relates to a suspended symmetrical single-shaft shoulder temperature measurement device and a single-dual-shaft shoulder general-purpose force measuring device, which belongs to the field of welding technology. Background technique [0002] Friction Stir Welding (FSW) is a patented welding technology invented by the British Welding Institute (TWI) in 1991. Friction stir welding is a solid-phase connection. Compared with traditional friction welding and other welding methods, friction stir welding has many advantages that conventional fusion welding does not have. It is an environmentally friendly connection method. Since its invention, this technology has been widely used in aerospace, rail transit, automobile and electric power industries. [0003] Whether it is the traditional single shoulder friction stir welding or the emerging double shoulder friction stir welding, the interaction between the stirring head and the workpiece to be co...

AI Technical Summary

Problems solved by technology

[0004] At present, at home and abroad, there are few reports on the measurement of weld seam temperature and three-dimensional force measurement in the conventional single-shaft shoulder friction stir welding process. In addition, the research on double-shaft shoulder friction stir welding has just started. The clamping in the test is not particularly standardized, and it cannot well realize the measurement of the traveling resistance and lateral pressure during the welding process
