the utility model provides a switching device is used in ball screw installation, includes the switching cover, the switching cover is located screw-nut, just set up a plurality of first through-holes of being connected with the lathe on the switching cover terminal surface, and a plurality of second through-holes of being connected with screw-nut.
Furthermore, the first through holes and the second through holes are arranged at intervals.
Furthermore, a plurality of first through-holes divide into the multiunit on average to along switching cover axle center symmetric distribution in on the switching cover terminal surface.
Furthermore, the second through holes are evenly divided into a plurality of groups and evenly distributed among the first through holes.
Furthermore, the first through hole and the second through hole are arranged at intervals.
Furthermore, the second through holes correspond to the fixing holes in the screw rod nuts one to one and are arranged coaxially.
Furthermore, a gasket is arranged on the inner side surface of the connecting sleeve.
The utility model discloses technical scheme has following advantage and beneficial effect at least:
1. the utility model discloses when using, locate the screw-nut with the adapter sleeve on, then utilize the fixed orifices on second through-hole and the screw-nut to be connected, utilize first through-hole to install on the lathe, thereby screw-nut and lathe's being connected has been realized, not only make ball screw's precision and load-carrying capacity can satisfy the processing needs like this, and make ball screw nut's the size of the installation dimension and the nut seat mount pad position of lathe match more, thereby can satisfy the demand of the firm installation between different screw-nut and the lathe, application range is wider, and is more reliable and more stable.

Detailed Description
To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the attached drawings in the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Example 1
The utility model provides a switching device is used in ball screw installation, includes switching cover 3, 3 covers of switching cover are located screw-nut 2, just set up a plurality of first through-holes 31 of being connected with the lathe on 3 terminal surfaces of switching cover to and a plurality of second through-holes 32 of being connected with screw-nut 2. In addition, the lead screw 1 in the embodiment adopts a super-ground lead screw to replace a traditional P7-grade rolling lead screw, and the effective length of the nut is increased from 116mm to 148mm. The nut lead increases from 8mm to 10mm.
The utility model discloses when using, locate lead screw nut 2 with the adapter sleeve on, then utilize the fixed orifices on second through-hole 32 and the lead screw nut 2 to be connected, utilize first through-hole 31 to install on the lathe, thereby lead screw nut 2 and lathe's being connected has been realized, not only make ball screw 1's precision and load-carrying capacity can satisfy the processing needs like this, and make ball screw nut 2's the mounting dimension and the size of the nut seat mount pad position of lathe match more, thereby can satisfy the demand of the firm installation between different lead screw nuts 2 and the lathe, application range is wider, and is more reliable and more stable.
A plurality of the first through holes 31 and a plurality of the second through holes 32 are arranged at intervals, specifically, a manner of arranging one first through hole 31 and one second through hole 32 at intervals may be adopted, in other embodiments, a manner of arranging a plurality of groups of the first through holes 31 and a plurality of groups of the second through holes 32 at intervals may also be adopted, specifically, in this embodiment, six first through holes 31 and six second through holes 32 are arranged, and three of the first through holes 31 and three of the second through holes 32 are arranged in one group, that is, three first through holes 31 and three of the second through holes 32 are arranged at intervals; the mode of evenly distributed like this can be more simple and convenient when can be so that the fixing, can with lead screw nut 2 between fixed more firm, also can be fixed more firm between the lathe simultaneously.
