Positioning device

摘要

A positioning device having a rotatable and tiltable work table for placing components to be worked on. The device has a frame and a support mounted on the frame having bearings for rotatably supporting a housing. Pivotable linkage arms extend between the frame and the support for positioning the support between upper and lower positions. The support has the work table associated therewith which is rotatable and tiltable relative to the support. The work table is also rotatably mounted relative to the housing. A hydraulic motor and a gear operatively associated therewith are associated with the housing wherein the motor communicates with a hydraulic fluid tank provided at a position spaced from the support. A double-acting piston and cylinder assembly is provided to effect tilting movement of the work table through the housing. The cylinder is pivotably connected to the support. The piston rod is pivotably connected to a V-shaped yoke having first and second legs and a link pivotably connected to a bracket rigidly mounted on the housing. The first leg of the V-shaped yoke is pivotable about a first pivot point which is stationary relative to the support, and the second leg of the V-shaped yoke is pivotably connected to the link.
