Embodiment Construction

[0028] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0029] as attached Figure 1 to Figure 4 As shown, an integrated friction plug repair welding spindle head device includes a spindle head, an auxiliary support mechanism and a control system.

[0030] The spindle head includes a rotating shaft 16 responsible for rotation and an oil cylinder responsible for axial movement. The oil cylinder includes an outer casing 8 and a large rear cover 3 coaxially connected, and an inner casing 10 arranged in the outer casing 8 . O-rings 9 are respectively provided between the inner housing 10 and the outer housing 8 , and between the inner housing 10 and the rear large cover 3 to prevent leakage of hydraulic oil. The inner cavity of the outer shell 8 is the front cavity of the oil cylinder, and the inner...

Abstract

The invention discloses an integrated friction plug repair welding spindle head device, which includes a rotating shaft and an oil cylinder; the oil cylinder includes an outer shell, a large rear cover and an inner shell; oil port and the second oil port; the inner shell is arranged in the outer shell, and moves axially along the outer shell under the action of the oil in and out of the first and second oil ports, and by adjusting the pressure between the first and second oil ports difference to realize the control of welding axial load; the rear end of the inner casing is connected with a rear cover located in the rear cover, and the rear cover and the rear cover are respectively provided with guide rail sliders and axial Stroke limiting groove; the rotating shaft is arranged in the inner casing, and is matched with the inner casing through a bearing group; the front end of the rotating shaft is connected to the stopper rod, and the rear end is connected to the hydraulic motor. The invention has the characteristics of high integration, small size, light weight, and convenient disassembly, and can be installed on a mechanical arm to complete in-situ repair of structural defects and friction stir welding keyhole repair welding.

Description

technical field [0001] The invention relates to welding manufacturing technology, in particular to a friction plug welding spindle head device mainly used for in-situ repair of welding defects of aluminum alloy structures and friction stir welding keyhole repair. Background technique [0002] Friction plug repair welding is a solid-phase joining technology, which has the advantages of low welding temperature, small residual stress and deformation, and has broad application prospects, especially in aerospace, automobile, marine engineering and other fields. The basic process of friction plug welding can be described as: the stopper rod (consumable material) is driven by the driving device, and is fed axially while rotating at a high speed, and the stopper rod is subjected to a certain axial load during this process. After the contact between the stopper rod and the plug hole, a large amount of welding heat input is generated due to friction, and the workpiece to be welded bec...
