Friction welding machine axis adjusting device, sliding table mechanism and friction welding machine

Abstract

The friction welding machine axis adjusting device comprises a plurality of tensioning mechanisms and a plurality of adjusting mechanisms, the tensioning mechanisms are used for being arranged on the side, away from a tailstock integrated body, of a sliding table, and the tailstock integrated body is used for installing a tailstock workpiece; each tensioning mechanism can drive the tailstock integrated body to move in the direction close to the sliding table so as to limit axial and radial movement of the tailstock integrated body. The adjusting mechanisms are used for being fixedly arranged on the sliding table, the multiple adjusting mechanisms are distributed around the tailstock integrated body, and when the tailstock integrated body is in the position adjustable state, the radial position of the tailstock integrated body can be adjusted and locked through the multiple adjusting mechanisms; the invention further provides a sliding table mechanism which comprises a tailstock integrated body, a sliding table and the friction welding machine axis adjusting device. The invention further provides a friction welding machine which comprises the sliding table mechanism. According to the axis adjusting device of the friction welding machine, the sliding table and the friction welding machine, time and labor are saved in the axis adjusting process.

Description

technical field [0001] The invention relates to the technical field of friction welding, in particular to an axis adjustment device for a friction welding machine, a slide mechanism and a friction welding machine. Background technique [0002] As an important component of an aero-engine, the compressor is a mechanical device that transmits mechanical energy to the gas to complete the compression of the gas medium in the thermal cycle of the engine, thereby increasing the gas pressure. As an important part of the compressor, the compressor disk is traditionally connected by mechanical bolts and electron beam welding. However, the mechanical connection results in a larger thickness and higher quality of the compressor disk, which increases the overall engine pressure. The weight is not conducive to the improvement of the thrust-to-weight ratio and performance of the aero-engine. However, the electron beam welding method has high heat input, large welding deformation, high resi...

Problems solved by technology

As an important part of the compressor, the compressor disk is traditionally connected by mechanical bolts and electron beam welding. However, the mechanical connection results in a larger thickness and higher quality of the compressor disk, which increases the overall engine pressure. The weight is not conducive to the improvement of the thrust-to-weight ratio and performance of the aero-engine. However, the electron beam welding method has high heat input, large welding deformation, high residual stress after welding, and difficult welding of dissimilar materials. It is difficult to fully meet the needs of aero-engine compressors. The design and manufacturing requirements of the disk seriously restrict the improvement of the overall performance of the aero-engine. Friction welding can meet the welding requirements of the workpiece. Since the friction welding device in the prior art is manufactured, the position of the axis of the tailstock and the axis of the clamp It cannot be adjusted, so for workpieces with special welding requirements, the problem of axis accuracy deviation often occurs, resulting in workpieces that do not meet the welding requirements
