Force platform for friction stirring welding machine

Abstract

The invention discloses a force platform for a friction stirring welding machine. The force platform comprises a stirring head, a working platform, a transverse guide rail, an upper table top of the force platform, a down force sensor, a lower table top of the force platform, a vertical plate, a forward resistance sensor mounting plate, a longitudinal guide rail, a forward resistance sensor and a cushion block, wherein the stirring head is fixed above the working platform; the working platform is arranged on the transverse guide rail by a transverse sliding block; the transverse guide rail is arranged on the upper table top of the force platform of the down force sensor; the vertical plate is arranged at the front end of the lower table top of the force platform; the vertical plate is connected with the forward resistance sensor mounting plate by the longitudinal guide rail provided with a longitudinal sliding block; the vertical plate is connected with the working platform by a stud provided with double nuts. The force platform can be directly applied to the existing friction stirring welding machine tool, and is capable of recording the curve of the change of the down force and the forward resistance along with the welding process during work; the force platform also has a clamping function, so that a workpiece can be conveniently clamped.

Description

technical field [0001] The invention relates to the field of real-time measurement of machine tool processing, in particular to a force measuring platform for a friction stir welding machine. Background technique [0002] Friction Stir Welding (Friction Stir Welding referred to as FSW) is an invention patent proposed by the British Welding Institute (TWI) in October 1991. The friction stir welding process was initially mainly used to solve the welding of low-melting point materials such as aluminum alloys. TWI has conducted more research on the characteristics and applications of the friction stir welding process. [0003] At present, the research has found that the downward pressure of the stirring head shoulder on the workpiece in the friction stir welding process and the forward resistance of the stirring head during feeding are inseparable from the welding quality. Ensuring that the working force is constant throughout the welding process can greatly improve the quality...
