Claims

[Scope of utility model registration request]

(1) In a device that linearly moves a driven body using a feed screw and a nut, the axis that coincides with the feed screw is the Z axis, the axis perpendicular to the Z axis is the X axis, and the Z axis and the X-Z plane The axis that is orthogonal to The nut is supported so that it can rotate minutely with respect to the X and Y axes connected to the bearing, and is constructed so that each movement can be performed independently of each other, thereby eliminating minute errors in the direction perpendicular to the Z axis. A screw feeding device designed to absorb movement.

(2) When fixing the nut to the driven body, a frame A has a pair of upper and lower plates made of elastic bodies and a pair of side plates fixed to the face plate and the back plate, and a frame that supports the surrounding frame A via a shaft and a bearing. A utility model registration claim characterized in that the nut is fixed to the frame A of a frame consisting of a frame B and a frame C fixed to a driven body that supports the surrounding frame B via a shaft and a bearing. The screw feeding device according to scope 1.

(3) When fixing the nut to the driven body, use an elastic body
. A frame A has a pair of upper and lower plates and a pair of side plates fixed to a face plate and a back plate, and a frame B supports the surrounding frame A via a shaft and a bearing. Utility model registration claim 1, characterized in that the frame B is supported by the driven body via a shaft and a bearing.
Screw feeding device as described in section.

(4) The pair of upper and lower plates and the pair of side plates are made into elastic bodies by providing a plurality of constrictions at intervals in the longitudinal direction, as described in claims 2 and 3 of the utility model registration claims. screw feeder.
