    电机端部中频钎焊结构说明

    端部钎焊机床我公司设计了两种形式,供用户选择:

    一种形式为可旋转型,在装电机转子时,电机的轴可以先接触下部顶尖,然后通过顶尖的下落使导条和端部平稳的放置在焊接感应器上,防止装电机转子时对感应器的冲击。并且在分段焊接时可以通过下顶尖的上升对电机转子进行旋转操作。

    另一种形式为简单结构,通过吊车直接将工件(端部和导条)放在感应器上进行焊接。在分段焊接时,通过吊车对电机转子的焊接部位进行旋转。

    下面对这两种机床进行详细描述:

    1、可旋转型钎焊机床

    1.1、机床使用范围

    机床适合于转子端部外径尺寸范围为φ396mm-φ1262mm,厚度22mm-80mm,轴最长4.5米,重量小于10吨的电机端部与转子导条的焊接。

    1.2 机床结构特点

    机床主要由机架、工件扶架、蜗轮副旋转机构、液压顶缸和液压站、可三位移动的变压器支架等组成。焊接时在吊装电机转子时,电机的轴可以先接触下部顶尖,然后通过顶尖的下落使导条和端部平稳的放置在焊接感应器上,防止装电机转子时对感应器的冲击。

    整体焊接时,一次焊接完成后将焊接好的电机转子吊走掉头再进行另一端的焊接。

    在分段焊接时,焊接完一段后,通过下顶尖的上升和蜗轮副旋转机构对电机转子进行旋转操作。

    通过调整可三位移动的变压器支架,可以方便的实现感应器与端部之间的对中。

    感应器托盘用于支撑感应器,由于感应器有导磁体,不会对托盘加热,所以托盘用金属材料制作。

    支架根据最大电机的直径和轴长进行设计。

    下部顶尖设计为可更换型。在焊接不同的电机端部时,只要更换顶尖即可。

    感应器和变压器之间采取硬连接,这样调节变压器时同时也就调节了感应器。

    为防止顶起电机转子进行旋转时转子倾斜,设计有4个工件扶架。只需要调整其相对位置就可以适应不同直径的电机转子。

    2、不带旋转上升机构的机床

        此机床结构如上图所示。工作原理除不包括液压上升和蜗轮副旋转机构以及工件扶架外,在装卸电机转子以及分段焊接中间旋转时,用吊车进行。

    Motor end intermediate frequency brazing structure description

    End brazing machine tool Our company designed two forms for users to choose:

    One form is rotatable. When the rotor of the motor is installed, the shaft of the motor can contact the lower tip first, and then the tip and the end are smoothly placed on the welding inductor by the falling of the tip to prevent the induction of the rotor of the motor. Impact of the device. And in the segment welding, the rotor of the motor can be rotated by the lower tip.

    The other form is a simple structure in which the workpiece ( end and bar) is placed directly on the inductor for welding by a crane . In the case of segment welding, the welding portion of the motor rotor is rotated by a crane.

    The two machines are described in detail below:

    , rotatable brazing machine

    1.1 , the scope of use of machine tools

    Machine end of the rotor is adapted to the outer diameter size range φ396mm-φ1262mm, a thickness of 22mm-80mm, the longest axis of 4.5 m, the weight of the motor is smaller than the welded end portion of the rotor and the guide bar 10 tons.

    1 .2 , machine structure characteristics

    The machine tool mainly consists of a frame, a workpiece support frame, a worm gear pair rotation mechanism, a hydraulic top cylinder and a hydraulic station, and a three-position movable transformer bracket. When hoisting the rotor of the motor during welding, the shaft of the motor can first contact the lower tip, and then the tip and the end are smoothly placed on the welding inductor by the falling of the tip to prevent the impact on the inductor when the rotor of the motor is mounted.

    In the whole welding, after the welding is completed, the welded motor rotor is hoisted off and the other end is welded.

    In the segment welding, after the welding is completed, the rotor of the motor is rotated by the lower tip rising and the worm wheel rotating mechanism.

    The alignment between the inductor and the end can be conveniently achieved by adjusting the transformer holder that can be moved three positions.

    The sensor tray is used to support the sensor. Since the sensor has a magnetizer and does not heat the tray, the tray is made of a metal material.

    The bracket is designed according to the diameter and shaft length of the largest motor.

    The lower top is designed to be interchangeable. When welding different motor ends , just replace the tip.

    A hard connection is made between the inductor and the transformer, so that the inductor is also adjusted when the transformer is adjusted.

    To prevent the inclination of the rotor when the motor rotor is rotated from the top, there are four design help workpiece carrier. It is only necessary to adjust the relative position to adapt to the rotor of different diameters of the motor.

    , machine tools without rotating ascending mechanism

    This machine structure is shown in the figure above. The working principle is carried out by a crane when it does not include the hydraulic ascent and the worm gear rotating mechanism and the workpiece support, when the motor rotor is loaded and unloaded and the segment welding is rotated.
