Detailed Description

In order to more clearly illustrate the embodiments of the present utility model or the technical solutions in the prior art, the drawings that are required to be used in the embodiments will be briefly described below. It is apparent that the drawings in the following description are only some embodiments of the present utility model, and that other drawings may be obtained from these drawings without inventive effort for a person of ordinary skill in the art.

The present utility model will be described in detail below with reference to the drawings and the specific embodiments, which are not described in detail herein, but the embodiments of the present utility model are not limited to the following embodiments.

Referring to fig. 1 and 2, the present utility model provides a special load-bearing device for turning lathe, comprising a bottom plate 1, a housing 2, a driving assembly 3 and a load-bearing platform 4.

According to one embodiment of the utility model, the central part of the base plate 1 is provided with a central shaft 11, and the central shaft 11 is rotatably provided with a bearing 12. The shell 2 is positioned above the bottom plate 1 and fixedly connected with the bottom plate 1, the driving assembly 3 is positioned in the shell 2, the driving assembly 3 comprises a driving bevel gear 31 and a driven bevel gear 32 which are meshed with each other, a grip 33 is arranged on the driving bevel gear 31, and one end of the grip 33 extends out of the shell 2. The driven bevel gear 33 is fixedly connected with a screw sleeve 34, and the screw sleeve 34 is positioned on the upper side of the bearing 12 and fixedly connected with the bearing 12. The bearing platform 4 is located above the shell 2, the bearing platform 4 is connected with a transmission shaft 41, the bearing platform 4 and the transmission shaft 41 are in an integrated structure, and the transmission shaft 41 is provided with external threads and is in threaded fit with the threaded sleeve 34.
