Abstract
The invention discloses a main shaft of a friction stitch welding machine tool. The main shaft mainly comprises a high-speed rotating hydraulic motor, a feeding hydraulic oil cylinder, a central spindle, a reducing sleeve and the like, wherein the hydraulic motor is arranged on a piston of the feeding hydraulic oil cylinder; feeding movement of the main shaft is realized along with the movement of the piston; the inside of the piston is hollow; the central spindle is arranged inside the piston through a plurality of rolling bearing, and is connected with an output shaft of the hydraulic motor so as to realize high-speed rotation of the main shaft; the central spindle has a hollow structure and is used for reducing moment of inertia during high-speed rotation; and the reducing sleeve is used for arranging a milling cutter and a stopper rod needed by friction stitch welding. The main shaft has a compact structure, high output rotating speed and large axial bearing capacity, and is convenient for controlling feeding movement.
Description
Technical field
The present invention relates to a kind of main shaft, especially be applicable to the main shaft of friction stitch welding lathe.
Background technology
Friction stitch welding can be regarded as along the combination of a series of friction plug weld unit formations of crackle arrangement in form.The unit formation process is: preboring welding hole on mother metal at first, the smaller stopper of diameter rotates the insertion welding hole at a high speed then, simultaneously on stopper, apply axial force and keep certain feed speed, the temperature rising of the contact interface of stopper and mother metal because of frictional heat, the resistance of deformation of stopper reduces, plasticity improves, the oxide-film fragmentation at interface, stopper produces plastic deformation and flows, constantly fill the continuous discharge of welding hole and surface impurity along with the plastification metal material, contact interface moves from welding hole bottom rapidly, reaches close between the metal material of plastification simultaneously and the welding hole inner surface and combines.The shape of preboring welding hole and corresponding stopper can be cylindrical, also can be conical.Along crackle, a series of unit processes overlap mutually, have just formed complete weld seam.The form of overlap joint can be that order advances, and also can be to advance at interval.
Friction stitch welding is mainly used in heavy wall steel construction crackle reparation, particularly underwater steel construction.Friction stitch welding is used for the underwater steel construction crackle reparation, and the outstanding advantage of comparing with traditional underwater welding method such as high pressure welding is: welding parameter is not subjected to water depth effect, does not need to evaluate welding parameter again according to the depth of water, and the shallow water parameter can be directly used in deep water; Operation is directly implemented in water, does not need to build special spaces such as hyperbaric environment; Can be supporting with ROV, realize a complete set of operation full automation, break through the restriction of the saturation diving degree of depth, thereby might really impel under water interconnection technique to move towards deep water for the first time; Can be used for the reparation of ocean platform crackle, also can be used for the not stopping transportation reparation of submarine pipeline.
In order to reduce the underwater maintenance operating cost, to improve repairing quality, particularly adapt to the needs that marine petroleum development has entered super deepwater field, the present invention proposes the critical component friction stitch welding machine tool chief axis that is used for the friction stitch welding lathe.
Summary of the invention
According to background technology, the objective of the invention is to avoid above-mentioned deficiency, a kind of compact conformation is provided, the output speed height, axial carrying capacity is big, and Feed Motion Control is the friction stitch welding machine tool chief axis easily.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of friction stitch welding machine tool chief axis mainly is made up of high speed rotary hydraulic motor, feeding hydraulic jack, mandrel and reducing sleeve etc.; Hydraulic motor is installed on the feeding hydraulic cylinder piston, along with the piston motion realizes the axis feeding motion; Internal piston is hollow, and mandrel is installed in internal piston by plurality of rolling bearings, and is connected with hydraulic motor output shaft, realizes that main shaft rotates at a high speed; Mandrel is a hollow-core construction, is used to reduce the rotary inertia when rotating at a high speed; Reducing sleeve is used to install needed milling cutter of friction stitch welding and stopper.
The friction stitch welding experimental provision of the present invention's design has following advantage:
(1) hydraulic motor is installed on the feeding hydraulic cylinder piston, and motor and oil cylinder are realized the high speed rotation and the feed motion of main shaft, compact conformation respectively.
(2) mandrel is a hollow-core construction, can reduce the rotary inertia when rotating at a high speed effectively.
(3) adopt hydraulic drive, the output speed height, axial carrying capacity is big, and Feed Motion Control is convenient, can satisfy the friction stitch welding technological requirement.
