Abstract
A multiple station transfer machine in which workpieces are located and supported in pallets and transferred sequentially through said machine and precisely located in each station along the transfer line, a three point locating system in which each pallet is located in one direction at spaced pressure points by a force applied in the direction of and midway between said points. The force application is applied by complemental wedge surfaces which can shift the pallet to cause it to meet the spaced pressure points, after which the pallet is clamped. A sequential actuator first locates and then clamps the pallet into a registry position. Slide rails for lineal transfer of the pallets are arranged to shift vertically relative to other supports for the pallets at each station, so the rails may be shifted to a non-interferring position prior to a clamping sequence so variations in slide rail dimensions due to wear and other influences will not affect the vertical registry of the clamped pallets.
