    • A welding wire feeder including an alignment tongue (74) and groove (76) connection between a clamp arm (66) and a welding drive assembly housing is provided. In certain embodiments, the alignment tongue (74) extends from an end of the clamp arm (66) opposite a pivot point (68, 78) about which the clamp arm (66) rotates relative the assembly housing. The corresponding alignment groove (76) may be formed in the assembly housing to receive the alignment tongue (74) when the clamp arm (66) is rotated such that a drive wheel (50) mounted on the clamp arm (66) contacts a drive wheel (48) mounted on the assembly housing. In addition, a tensioner (70) may be pivoted into a groove (88) in the clamp arm (66) to transfer a compressive force through the clamp arm (66), forcing the drive wheels (48, 50) together. The alignment tongue (74) and groove (76) may reduce lateral displacement of the clamp arm (66) relative to the assembly housing that may be caused by a force transferred to the clamp (66) arm as the tensioner (70) is pivoted.
    • 提供一种包括对准舌片(74)和夹紧臂(66)和焊接驱动组件壳体之间的凹槽(76)连接的焊丝馈线。 在某些实施例中,对准舌片(74)从夹持臂(66)的与枢转点(68,78)相对的端部延伸,夹持臂(66)围绕其枢转组件壳体旋转。 当夹紧臂(66)旋转时,对应的对准槽(76)可以形成在组件壳体中以接收对准舌部(74),使得安装在夹持臂(66)上的驱动轮(50)接触驱动 轮(48)安装在组件壳体上。 此外,张紧器(70)可以枢转到夹紧臂(66)中的凹槽(88)中,以将压缩力传递通过夹紧臂(66),迫使驱动轮(48,50)在一起。 定位舌片(74)和凹槽(76)可以减小夹紧臂(66)相对于组件壳体的横向位移,该张紧臂(66)可以由张紧器(70)枢转时传递到夹具(66)臂的力引起 。
