The frame is secured to a pallet of the machining center, and the platen is tilted in response to rotation of twin ball screws driven by a wrench transferred to the spindle of the machining center by an automatic tool changer. In each position, the platen is precisely located and clamped to the frame by a plurality of units each including a shot pin which has a threaded end portion for engaging a corresponding nut within the platen in response to rotation by a dual-torque wrench also transferred to the spindle by the tool changer.

Abstract: Across the surface and around two opposite sides of a table top are looped two elastic hold down straps. A third elastic hold down strap is looped around these two straps and the other two sides of the table top. Lips grip an edge of the table top. The table top is slidably mounted on rails held parallel by two parallel supports each pivotally connected to ends of arms. The arms are pivotally connected at their other ends to a shaft. Upper ends of table legs are pivotally connected to the shaft. Interspaced between arms and legs on the shaft are spacers and a tube through which the shaft passes. When a cap nut is secured on one end of the shaft and a knob is screwed onto threads at the other end of the shaft, arms and legs are pressed together preventing them from pivoting around the shaft and locking the table top in a chosen position of height and inclination. Springs connecting arms and legs bias arms to rise to a vertical position when the knob is loosened.
