Clamping device of friction welding machine

Abstract

The invention discloses a clamping device of a friction welding machine and belongs to an auxiliary tool of a friction welding machine. The clamping device structurally comprises a moving clamp and a fixed clamp; the moving clamp is connected with a clamping cylinder; the right end surface of the moving clamp is a vertical plane; the section of the left end surface of the fixed clamp is V-shaped; the left and right ends of a clamp body are provided with a left end plate and a right end plate correspondingly; a material supporting plate is arranged on the middle position of the upper part of the clamp body, and the lower part of the clamp body is provided with a linear guide rail; the moving clamp is arranged on a left slide block; the fixed clamp is arranged on a right slide block; the fixed clamp is connected with a fixed clamp regulating device through the right slide block; the moving clamp is connected with the clamping cylinder through the left slide block; a to-be-welded bar material is clamped between the moving clamp and the fixed clamp; and the rear of the to-be-welded bar material is in contact with a main cylinder located on a bed body. The clamping device of the friction welding machine, disclosed by the invention, has the characteristic that the defects of clamping instability of the clamps, complex worker regulation processes and the like in a daily friction welding production process are overcome.

Description

technical field [0001] The invention relates to an accessory tooling of a friction welding machine, in particular to a clamping device of a friction welding machine. Background technique [0002] Friction welding is a solid-state welding method that achieves welding. Under the action of pressure, under the action of constant or increasing pressure and torque, the relative motion between the welding contact end surfaces is used to generate friction heat and plastic deformation heat on the friction surface and its surrounding areas, so that the temperature of the surrounding areas rises to In the temperature range close to but generally lower than the melting point, the deformation resistance of the material is reduced, the plasticity is improved, and the oxide film on the interface is broken. A solid-state welding method that achieves welding. [0003] The biggest difference between friction welding and traditional fusion welding is that during the whole welding process, th...
