Abstract
The invention discloses a self-adjustment connecting device and a screw-nut transmission device using the same. The self-adjustment connecting device comprises a base and a nut fixing seat, wherein the nut fixing seat is used for fixing the screw nut; a floating insertion structure is arranged between the nut fixing seat and the base; the floating direction of the floating insertion structure is perpendicular to the axial direction of the screw nut; and the base and the nut form a drag fit in the axial direction of the screw nut through the floating insertion structure. In the invention, the traditional integrated connecting seat is separately arranged, so that the nut fixing seat can slide in the radial direction of the screw nut relative to the base. In the working process, when the elongated screw shifts in the radial direction, the nut fixing seat which is rotatably matched with the screw can move in the preset direction relative to the base, thereby solving the problem of clamping in the elongated screw transmission process.

The present invention is arranged the connecting base branch of traditional one; And make the screw fixed base can be with respect to base radially sliding along feed screw nut; In the course of the work; When radial displacement appears in elongated leading screw, the screw fixed base that cooperates with leading screw rotation can be relatively and base along the moving radially of feed screw nut, thereby the jam problem when having solved elongated lead screw transmission; Tongue of the present invention and socket can be arranged on screw fixed base and the base flexibly; The matching gap of the matching gap of screw fixed base and socket and tongue and socket bottom is greater than the downwarp displacement of leading screw; Described tongue and socket are perpendicular to the circular runout displacement of the axial free gap of feed screw nut greater than leading screw; In the time of can guaranteeing leading screw generation radial displacement like this; Between screw fixed base and the socket, impingement phenomenon can not take place between tongue and the socket, guaranteed the proper functioning of screw and connection set; Tongue and socket can be fixed or the one correspondence is arranged on base and the screw fixed base according to actual conditions.
The present invention also aims to provide a kind of leading screw screw transmission device, the jam problem when being used to solve elongated lead screw transmission.
For realizing above-mentioned purpose; The present invention adopts following technological scheme: a kind of leading screw screw transmission device; Comprise leading screw, feed screw nut and connection set; Described connection set comprises base and the screw fixed base that is used for fixing feed screw nut, and feed screw nut is fixed on the screw fixed base, is provided with the inserting structure of floating between described screw fixed base and the base; The unsteady direction of the inserting structure of should floating is perpendicular to the axial direction of feed screw nut, realizes the cooperation that drags along the axial direction of feed screw nut through the inserting structure of floating between base and the screw fixed base.
Described unsteady inserting structure comprises tongue and the socket that cooperates with it; Tongue and socket are slidingly matched with the two side that is mated of socket on perpendicular to the direction of feed screw nut axis; Tongue is arranged on screw fixed base or the base, and the socket correspondence is arranged on base or the screw fixed base.
The matching gap of the matching gap of described screw fixed base and socket and tongue and socket bottom is greater than the downwarp displacement of leading screw, and described tongue and socket are perpendicular to the circular runout displacement of the axial free gap of feed screw nut greater than leading screw.
Described tongue is fixedly installed on screw fixed base or the base, and described socket correspondence is fixedly installed on base or the screw fixed base.
