Abstract
The utility model provides a machine tool with a central screw rod, which comprises a big carriage and the screw rod arranged in the middle of the big carriage. One end of the screw rod is connected with a motor by a coupling. The motor is fixed on one side of the big carriage by a motor seat. The other end of the screw rod is provided with a rolling bearing and a bearing support. The bearing support is fixed on the other side of the big carriage. By the machine tool with the central screw rod, which is provided by the utility model, the screw rod is arranged at the middle position of the big carriage, both left and right ends of the machine tool are stressed uniformly and the processing force is concentrated so as to integrally improve stability and processing accuracy of the machine tool in the operation process.
Description
Technical field
The utility model relates to the technical field of lathe, the mid-lathe of particularly a kind of screw mandrel.
Background technology
Existing machine tool generally adopts Z to screw mandrel, and described screw mandrel is installed in the outside of lathe bed, is fixed on an end of saddle, therefore when processing work, its power is carried in planker one end, so more or less has the low-angle skew, can have influence on the machining accuracy of lathe.
Therefore, in carrying out the utility model creation process, the inventor finds the Z of existing machine tool employing to screw mandrel, and when processing work, stressed planker one end that is carried on its screw mandrel can produce the low-angle skew, thereby has influence on the machining accuracy of lathe
The utility model content
In view of this, the utility model embodiment has proposed higher, the stable better mid-lathe of screw mandrel of a kind of precision.
For solving the problems of the technologies described above, the purpose of the utility model embodiment is achieved through the following technical solutions:
The lathe that the screw mandrel that the utility model provides is mid-, comprise saddle, be installed in the middle screw mandrel of saddle, described screw mandrel one end links to each other with motor by shaft coupling, described motor is fixed on a side of saddle by motor cabinet, the described screw mandrel other end is equipped with rolling bearing and bearing block, and described bearing block is fixed on the opposite side of saddle.
Preferably, described screw mandrel one end also is equipped with the preceding round nut of screw mandrel, packing ring and angular contact ball bearing.
Preferably, the centre of described screw mandrel also is with the feed screw nut, and described feed screw nut connects load by feed screw nut's seat.
The lathe that the screw mandrel that the utility model provides is mid-, because screw mandrel is installed in the centre position of saddle, evenly the processing dynamics is concentrated for two ends, the lathe left and right sides stressed, stability and machining accuracy during the therefore whole operation that has improved lathe.
Description of drawings
Fig. 1 is the perspective view of the mid-lathe of the utility model screw mandrel.
The specific embodiment
The utility model provides a kind of screw mandrel mid-lathe.The mid-lathe of described screw mandrel comprises saddle, is installed in the middle screw mandrel of saddle, described screw mandrel one end links to each other with motor by shaft coupling, described motor is fixed on a side of saddle by motor cabinet, the described screw mandrel other end is equipped with rolling bearing and bearing block, and described bearing block is fixed on the opposite side of saddle.
Further describe below in conjunction with specific embodiment.
See also Fig. 1, be the perspective view of the mid-lathe of the utility model screw mandrel.
Described lathe comprises motor 1, motor cabinet 2, shaft coupling 3, the preceding round nut 4 of screw mandrel, packing ring 5, angular contact ball bearing 6, screw mandrel 7, feed screw nut 8, feed screw nut's seat 9, nut seat base 10, saddle 11, deep groove ball bearing 12 and bearing block 13.
Described motor 1 is fixed on by motor cabinet 2 on the side of saddle 11 of bed piece, and links to each other by an end of shaft coupling 3 and screw mandrel 7.Described screw mandrel 7 one ends also are equipped with the preceding round nut 4 of screw mandrel, packing ring 5 and angular contact ball bearing 6.
The other end of described screw mandrel 7 is equipped with deep groove ball bearing 12 and bearing block 13.Described bearing block is fixed on the opposite side of saddle 11 of bed piece.
Therefore, described screw mandrel 7 is installed in the centre position of saddle 11.
The centre of described screw mandrel 7 also is with feed screw nut 8, and described feed screw nut 8 connects load by feed screw nut's seat 9.
Because described screw mandrel 7 is installed in the centre position of saddle 11, lathe adds man-hour, two ends, the lathe left and right sides stressed evenly, so saddle can not be offset, and mid-screw mandrel and main shaft are on the same vertical plane, after it is had an effect, do not need to transmit in many ways, can arrive Working position, make the processing dynamics concentrate, can not shake the stability during the therefore whole operation that has improved lathe; After the stability of lathe improved, it is more accurate that the machining accuracy of lathe just becomes naturally; Lathe stability improves, and the vibrations during machine tooling diminish, and it is better that the fineness of product will become; In addition, mid-screw mandrel, owing to be positioned at the centre of saddle, it is relatively good that protection can be done, its service life also can be longer.
In sum, the mid-lathe of screw mandrel that the utility model embodiment is provided because screw mandrel is installed in the centre position of saddle, two ends, the lathe left and right sides stressed evenly, the processing dynamics is concentrated, stability and machining accuracy during the therefore whole operation that has improved lathe.
More than the mid-lathe of screw mandrel that the utility model embodiment is provided be described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used to help to understand the technical scheme that the utility model discloses; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
