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

Abstract

The invention discloses a suspension symmetric single shaft shoulder temperature measuring and single shaft shoulder and double shaft shoulder universal force measuring device. The device comprises an upper platform, a lower platform and a supporting device for connecting the upper platform with the lower platform. A groove is formed in the upper platform. A containing groove is formed in the bottom of the groove. A punching sheet is arranged in the containing groove. First pits are formed in the punching sheet. A temperature measuring cushion plate is installed on a first ball in the groove. First sensor containing grooves are formed in the periphery of the groove in the upper platform. First pressure sensors are placed in the first sensor containing grooves. Second sensor containing grooves are formed in the lower platform, and second pressure sensors are arranged in the second sensor containing grooves. According to the suspension symmetric single shaft shoulder temperature measuring and single shaft shoulder and double shaft shoulder universal force measuring device, the clamping requirements of a single shaft shoulder friction stir welding technology and a double shaft shoulder friction stir welding technology can be met at the same time, and measurement of the weld line temperature and the three-dimensional force in the single shaft shoulder welding process and measurement of the advancing resistance and the lateral force in the double shaft shoulder welding process can also be achieved.

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...
