Abstract
The utility model belongs to Z axle screw supporting structure field provides a Z axle supporting structure convenient to lead screw alignment in lathe, including support, accessory plate of welding or casting material, support one end is equipped with the first bearing mounting hole, and the other end is open type structure, the accessory plate passes through coupling screw, locating pin to be fixed in the opening lower part of support, is equipped with the second bearing mounting hole on the accessory plate, the coaxial of first bearing mounting hole and second bearing mounting hole. The utility model discloses Z axle supporting structure convenient to lead screw alignment, simple structure, convenient to use guarantee during lathe Z axle lead screw installation adjustment action, open type support alignment lead screw center is accurate.
Description
Technical Field
The utility model belongs to Z axle screw supporting structure field in the lathe, concretely relates to Z axle supporting structure convenient to lead screw alignment is applicable to lathe such as large-scale or heavy lathe, milling machine, boring machine in the well.
Background
When a machine tool, such as a lathe, a milling machine, or a boring machine, performs a Z-axis screw mounting adjustment operation, a fitter needs to align a bracket on which a Z-axis screw is mounted. After the screw rod is assembled in the bracket, the axial lead of the screw rod is parallel to the moving direction of the driving part, so that the moving part can stably and reliably run. At present lathe Z axle lead screw support shortens lead screw length in order to save space, and there is the bearing mounting hole structure support one end of making into, and one end does not have the open type structure of bearing mounting hole, has just so led to the support not have 2 end locating hole structures of assembly debugging usefulness, and support alignment lead screw center is inaccurate.
Disclosure of Invention
The utility model aims at providing a Z axle supporting structure convenient to lead screw alignment, its simple structure, convenient to use are provided to the unsafe problem in open type support alignment lead screw center in the installation adjustment action of lathe Z axle lead screw among the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a Z-axis support structure convenient for lead screw alignment comprises a support and an auxiliary plate, wherein the support is made of welding or casting materials, one end of the support is provided with a first bearing mounting hole, the other end of the support is of an open structure, the auxiliary plate is fixed to the lower portion of an opening portion of the support through a connecting screw and a positioning pin, the auxiliary plate is provided with a second bearing mounting hole, and the first bearing mounting hole and the second bearing mounting hole are coaxial.
When the adjustment support is installed by an assembler, the first bearing mounting hole and the second bearing mounting hole at two ends are installed in the inspection sleeve, the inspection rod penetrates into the inspection sleeve, the movable component guide rail can be used as a reference conveniently, the support is adjusted, the center of the inspection rod is aligned, after the precision of the support is adjusted, the auxiliary plate of the opening part can be detached, the open-type structure at one end of the support is restored, and the installation of the lead screw is facilitated.
The utility model discloses Z axle supporting structure convenient to lead screw alignment, simple structure, convenient to use guarantee during lathe Z axle lead screw installation adjustment action, open type support alignment lead screw center is accurate.

Fig. 2 is a sectional view a-a of fig. 1.
FIG. 3 is a schematic view of a Z-axis support structure without an auxiliary plate.
Fig. 4 is a sectional view a-a of fig. 3.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the Z-axis support structure convenient for lead screw alignment in this embodiment includes a support 1 and an auxiliary plate 2, wherein one end of the support 1 is provided with a first bearing mounting hole 5, the other end of the support 1 is of an open structure, the auxiliary plate 2 is fixed on an opening portion of the support 1 through a coupling screw 3 and a positioning pin 4, and the auxiliary plate 2 is provided with a second bearing mounting hole 6.
As shown in fig. 3 and 4, the structure of the Z-axis support without the auxiliary plate is schematically shown. Namely, the structure schematic diagram of the screw rod center is aligned and the support is adjusted.
The working principle of the embodiment of the present invention is described in detail as follows. When the center of a screw rod is required to be aligned by a Z-axis screw rod support 1, an auxiliary plate 2 is fixed to the lower portion of an opening of the support 1 through a connecting screw 3 and a positioning pin 4, the support 1 and the auxiliary plate 2 are processed together, coaxiality of a first bearing mounting hole 5 and a second bearing mounting hole 6 is guaranteed, when an adjusting support is installed by an assembler, detection sleeves are installed in bearing holes at two ends, detection rods penetrate into the detection sleeves, a movable component guide rail can be conveniently used as a reference, the support is adjusted so as to align the center of the detection rods, after the accuracy of the support is adjusted, the support is fixed on a support installation surface, the auxiliary plate at the opening is detached after a pin is positioned, an opening type structure at one end of the support is restored, the screw rod is installed on the support, and parallelism of the screw rod center and the movable component guide rail.
Details not described in this specification are within the skill of the art that are well known to those skilled in the art.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
