Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
As shown in FIG. 1 to 3, a kind of leading screw travel mechanism that this utility model embodiment provides, including a pedestal 1, base
Seat 1 offers a strip groove 11 running through pedestal 1 along its length, and groove 11 both sides are separately installed with a guide rail 12,
It is slidably equipped with at least one slide block 13 on guide rail 12, slide block 13 is provided with a platen 2, in the present embodiment, each guide rail 12 is installed
There are two slide blocks 13, lay respectively at the corner of platen 2, be so conducive to the parallel and stable of platen 2；
Described groove 11 one end is installed with a clutch shaft bearing and supports seat 4, and described groove 11 other end is installed with one second axle
Holding support seat 5, described clutch shaft bearing supports and is provided with a leading screw 3 between seat 4 and the second bearing support block 5, leading screw 3 one end and one the
One bearing support block 4 is rotationally connected, and leading screw 3 other end and one second bearing support block 5 are rotationally connected, and the other end of leading screw 3 is worn
Cross the second bearing support block 5 to be rotationally connected for the motor 6 driving leading screw 3 to rotate with one；
