ABSTRACT:
Conventional apparatus for pressing the track links onto pin and bushings of the track chain during assembly thereof experience difficulty in aligning the links with the pin and bushings because the presses become somewhat loose and out of alignment. The subject apparatus overcomes this problem by providing a self aligning feature in the link locating and driving means. The link locating and driving member is mounted on the pressure plate that is attached to the press rams. A support plate is guided from the pressure plate by guides and resilient members that allow the support plate to shift with respect to the pressure plate with the aid of tapered noses on plungers supported by pressure barrels as the rams move forwardly to press the links onto the pin and bushings held in a fixture. In this manner any misalignment is accounted for by the self-aligning feature of the locating and driving members.
