Abstract
The utility model relates to a friction stir welding anti-pumpback main shaft, which effectively solves the problems that existing equipment cannot effectively detect and control welding pressure, and the like. According to the technical scheme, the friction stir welding anti-pumpback main shaft comprises a main shaft, wherein the main shaft is connected with a built-in motor; a piston shaft is concentrically mounted in the main shaft; a stirring head is fixed at the left end of the main shaft and is connected with the left end of the piston shaft through a stirring needle; the right end of the piston shaft is connected with a rotary joint placed outside the main shaft; a shaft shoulder is arranged on the piston shaft; the piston shafts on the left side and the right side of the shaft shoulder are connected with the main shaft through transmission devices in a left-and-right sliding mode; a closed first oil cavity and a closed second oil cavity are formed between the shaft shoulder and the left and right transmission devices; a first oil outlet and a second oil outlet are formed in the piston shafts in the first oil cavity and the second oil cavity respectively; and a first oil inlet and a second oil inlet which are communicated with the first oil outlet and the second oil outlet are formed in in the rotary joint. The friction stir welding anti-pumpback main shaft has a novel and unique structure and strong practicability, and can detect and control the welding pressure.
Description
Technical field
The utility model relates to the agitating friction soldering equipment, and particularly main shaft is taken out in the friction stir welding backspace.
Background technology
At present, the technical characterstic of friction stir welding is that weld metal does not melt, the fine grained texture of weld seam for forging, and operating environment is not limited, is suitable for the welding of large scale structure, technological parameter is few simultaneously, Stability margin of parameter is large, welding quality stable is the Solid-phase welding new technology of efficient, low-cost a, environmental protection, and existing friction stir welding backspace main shaft is mainly to control by mechanical displacement to realize that the shaft backspace takes out function, can not realize detection and control to welding pressure, use inconvenience.
Summary of the invention
For above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just is to provide a kind of friction stir welding backspace and takes out main shaft, has effectively solved existing equipment and can not effectively realize problems such as the detection of welding pressure and controls.
the technical scheme of its solution is, comprise main shaft, main shaft is connected with built-in motor, the axis of the piston is housed in main shaft with one heart, the main shaft left end is fixed with stirring-head, be connected through mixing needle between stirring-head and the axis of the piston left end, the axis of the piston right-hand member is connected with the swivel joint that is placed in main shaft foreign side, the shaft shoulder is arranged on the axis of the piston, the shaft shoulder is left, the axis of the piston on the right horizontally slips with main shaft through transmission device and is connected, the shaft shoulder is with left, form airtight the first oil pocket and the second oil pocket between right transmission device, on the axis of the piston in the first oil pocket and the second oil pocket, the first oil outlet and the second oil outlet are arranged respectively, the first fuel feed hole and the second fuel feed hole that communicate with the first oil outlet and the second oil outlet are arranged on swivel joint.
The utility model novel structure is unique, and is practical, can realize detection and control to welding pressure.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
provided by Fig. 1, the utility model comprises main shaft, main shaft 1 is connected with built-in motor 2, the interior the axis of the piston 3 that is equipped with one heart of main shaft 1, main shaft 1 left end is fixed with stirring-head 4, be connected through mixing needle 5 between stirring-head 4 and the axis of the piston 3 left ends, the axis of the piston 3 right-hand members are connected with the swivel joint 6 that is placed in main shaft 1 foreign side, the shaft shoulder 7 is arranged on the axis of the piston 3, the shaft shoulder 7 left sides, the axis of the piston on the right horizontally slips with main shaft 1 through transmission device 8 and is connected, the shaft shoulder 7 is with left, form airtight the first oil pocket 9 and the second oil pocket 10 between right transmission device 8, on the axis of the piston in the first oil pocket 9 and the second oil pocket 10, the first oil outlet 11 and the second oil outlet 12 are arranged respectively, the first fuel feed hole 13 and the second fuel feed hole 14 that communicate with the first oil outlet 11 and the second oil outlet 12 are arranged on swivel joint 6.
The axis of the piston on the said shaft shoulder 7 left and right limits horizontally slips with main shaft 1 through spline and is connected.
when the utility model uses, built-in motor 2 drives main shaft 1 and rotates, main shaft 1 drives mixing needle 5 and the axis of the piston 3 High Rotation Speeds, pass into pressure oil respectively in the first oil pocket 9 and the second oil pocket 10 by the first fuel feed hole 13 on swivel joint 6 and the second fuel feed hole 14, change its first fuel feed hole 13 by external pressure control valve, the pressure differential of the second fuel feed hole 14 realizes endwisely slipping of the axis of the piston 3 and to the Detection ﹠ Controling of welding pressure, the utility model is applicable to single shaft shoulder and twin shaft shoulder stirring-head, stir to eliminate the keyhole that welding is produced, be mainly used in the welding of closed curve weld seam, the utility model precision is high, control with device systems by pressure and form closed-loop control, control and the detection of main shaft pressure have been realized backspace is taken out, not only improved welding quality, also improve for follow-up welding procedure simultaneously reliable experimental data is provided.
The utility model novel structure is unique, and is practical, can realize detection and control to welding pressure.
