DEVICE FOR POSITIONING AN OBJECT IN SPACE

摘要

The subject of the invention is a device for positioning an object in space, comprising at least 4 plates, each one able to move with respect to another of said plates which is contiguous with it along one of the 3 axes of space, it being possible for the movement of one plate with respect to another plate to be guided by a tenon/mortise assembly in which said tenon is secured to one of the plates and its mortise is produced in the other plate, the spatial orientation of each of the tenon/mortise assemblies being different from the other 2 and along one of the 3 axes of space.

1. A device for positioning an object in space, comprising at least 4 plates, each one able to move with respect to another of said plates which is contiguous with it along one of 3 axes of space, a tenon/mortise assembly which guides the movement of one plate with respect to another plate in which said tenon is secured to one of the plates and its mortise is produced in the other plate, the spatial orientation of each of the tenon/mortise assemblies being different from the other 2 and along one of the 3 axes of space
wherein
said device is free of any compensating springat least one of the tenon/mortise assemblies is in the form of a dovetail;a preload aimed at limiting the movement of one plate with respect to another is applied laterally to one of the edges of the tenon of the tenon/mortise assembly, said preload limiting but not preventing the movement of said plates one relative to another;the movement of at least one plate relative to another plate is brought about by means of at least one micrometer screw able to act at least on one of the two plates that are to be moved one relative to the other, said micrometer screw being secured to one of said two plates, said micrometer screw being fixed in direct mesh with said plate;one plate is locked in the desired position relative to another plate independently for each of the tenon/mortise assemblies.
