Abstract: The present invention consists in the apparatus for use in welding a first component and a second component together by friction welding, comprising drive means operative to generate reciprocatory movement, a component holder operative to hold said first component, linking means operative to transmit reciprocatory movement from the drive means to the component holder so that in operation said first component performs reciprocatory heat-generating movement, pressure means operative to exert pressure on the component holder so that in operation said first component also performs welding movement, the linking means being such as to accommodate that welding movement during friction welding, and the pressure means being such as to accommodate that heat-generating movement during friction welding. The pressure means preferably comprises ram means operative to apply force to a non-reciprocating head which is connected to the component holder through flexible connecting means enabling heat-generating movement of the holder to be accommodated. The connecting means may comprise one or more hinged links but preferably comprises one or more flexible elements. These flexible elements may comprise flexible rods or bars but preferably comprise flexible blades so orientated as to prevent movement of the component holder in a direction transverse to its heat-generating movement. Movement of the head in a direction parallel with the reciprocatory heat-generating movement of the component holder is preferably resisted by guide means which nevertheless permits the head with the component holder to perform welding movement. The guide means is preferably constituted by roller means preloaded to prevent backlash or rattling in use.

Abstract translation: 本发明在于用于通过摩擦焊接将第一部件和第二部件焊接在一起的装置，包括可操作地产生往复运动的驱动装置，用于保持所述第一部件的部件保持器，用于将往复运动从 驱动装置到部件保持器，使得在操作中所述第一部件执行往复发热运动，压力装置可操作以对部件保持器施加压力，使得在操作中所述第一部件也执行焊接运动，所述连接装置为 适应摩擦焊接期间的焊接运动，并且压力装置能够适应摩擦焊接期间的发热运动。 压力装置优选地包括可操作地将压力施加到非往复式头部的压头装置，所述非往复式头部通过柔性连接装置连接到部件保持器，从而能够容纳待保持器的发热运动。 连接装置可以包括一个或多个铰链连杆，但优选地包括一个或多个柔性元件。 这些柔性元件可以包括柔性杆或杆，但是优选地包括柔性刀片，其被定向成防止部件保持器在横向于其发热运动的方向上移动。 头部在与部件保持器的往复发热运动平行的方向上的移动优选地被导向装置抵抗，然后导向装置允许具有部件保持器的头部执行焊接运动。 引导装置优选地由预装载的滚子装置构成，以防止使用中的反冲或晃动。
