    • A stud welding apparatus has a welding jig, guide frames and a cartesian coordinate type robot. This robot has a travelling frame, a robot main body, an elevating arm and a stud welding gun. Power supply passages are provided on the travelling frame, the robot main body and the elevating arm, respectively, such that electric power can be supplied from a welding power source to the stud welding gun via these power supply passages. The power supply passage provided on the travelling frame is formed in a first power supply bar which is fixed to the travelling frame and is elongated in a horizontal direction. A pressure type first power supply joint is provided on the robot main body and urges a contact member to be connected to the power supply passage provided on the robot main body into contact and away from the first power supply bar by means of a cylinder. The power supply passage provided on the elevating arm is formed in a second power supply bar which is fixed to the elevating arm and is elongated in a vertical direction. A pressure type second power supply joint is provided on the robot main body and urges a contact member to be connected to the power supply passage provided on the robot main body into contact and away from the second power supply bar by means of a cylinder.
    • 螺柱焊接装置具有焊接夹具,引导框架和笛卡尔坐标型机器人。 该机器人具有行走架,机器人主体,升降臂和螺柱焊枪。 供电通道分别设置在行车架,机器人主体和升降臂上,使得能够通过这些电源通道从焊接电源向螺柱焊枪供电。 设置在行走架上的供电通道形成在第一供电杆上,该第一供电杆固定在行走架上并在水平方向上伸长。 在机器人主体上设置压力型第一供电接头,并且将通过设置在机器人主体上的供电通路的接触构件推压通过气缸与第一供电杆接触和离开。 设置在升降臂上的供电通道形成在固定到升降臂上并在垂直方向上延伸的第二电源杆中。 在机器人主体上设置有压力型第二供电接头,并且将通过设置在机器人主体上的供电通路连接的接触构件通过气缸接触和远离第二供电杆。

    • A body frame for a motor bicycle includes a main frame, a head tube provided at a front end of the main frame and down tubes extending rearward from the main frame. The main frame, head tube and down tubes are cast with a light alloy into an integral form of a hollow and thin-wall structure. A production process of the body frame, wherein an integrally-formed core, which is formed into a shape similar to that of the body frame, is hollow and has good permability. A molten metal is charged into the mold and a vacuum is applied to the interior of the core. The molten metal is charged into a cavity defined between the core and the molding surface of the mold by a low-pressure casting method, and the molten metal is solidified so as to cast the body frame. A production apparatus of the body frame includes a liftable cope fitted to a vertical casting machine, a fixed drag, and slidable molds disposed in combination with the cope and being capable of horizontally sliding in a state that the cope is released from the drag. A body frame having both properties of light weight and high stiffness, and a production process and apparatus thereof is provided wherein casting defects and to provide a high-precision cast article, is provided.
    • 一种用于摩托车的车身框架包括主框架,设置在主框架前端的头管和从主框架向后延伸的下拉管。 主框架,头管和下管以轻合金铸造成中空和薄壁结构的整体形式。 主体框架的制造方法,其中形成为与主体框架类似的形状的整体形成的芯部是中空的并且具有良好的可容许性。 将熔融金属装入模具中,并将真空施加到芯部的内部。 将熔融金属通过低压铸造法加入到芯体和模具的成形表面之间的空腔中,并使熔融金属固化,从而铸造主体框架。 主体框架的制造装置包括安装在垂直铸造机上的可升降的上座板,固定的拖曳和可滑动的模具,与所述上座组合配置,并且能够在所述上钩从所述拖曳中释放的状态下水平滑动。 提供了具有轻质量和高刚度的两种特性的车体框架及其制造方法和装置,其中提供铸造缺陷并提供高精度铸造件。
