Description

A rotary table mechanism for a gantry drilling, boring and milling compound processing machine tool

technical field

The utility model relates to a rotary table mechanism, which is applied to a gantry drilling, boring and milling compound processing machine tool, and a double-column numerical control vertical lathe can be formed by borrowing the original gantry frame. the

Background technique

At present, there is no known rotary table mechanism for large-scale gantry drilling, boring and milling machines. When there is no large-scale drilling, milling and boring parts, they can only be idle. Products that require vertical lathe processing need to increase equipment and workshops, wasting resources and factory space. Generally, the main shaft of the main reducer is directly connected to the main shaft of the workbench, and the plane static pressure support is adopted between the workbench and the base, and there is no indexing mechanism. The rotation accuracy of the worktable in this support method is not high, which is easy to cause instantaneous size changes, complicated start-up process, and inconvenient operation. the

Detailed ways

Accompanying drawing has provided the specific embodiment of the utility model.

In the embodiment, as shown in FIG. 1 , 1 is a workbench, 2 is a base, 4 is an indexing mechanism, 5 is a main reducer, and 6 is a variable frequency speed regulating motor. As shown in Figure 2, 3 is a main shaft, 7 is a gear, 8 is a ring gear, and 9 is a large slewing bearing. The rotary table mechanism includes table 1, base 2, main shaft 3, indexing mechanism 4, main reducer 5, frequency conversion motor 6, gear 7, ring gear 8, large slewing bearing 9, main reducer 5 and indexing Mechanisms 4 are all fixed on the side walls of the base 2 . The complete mechanism of the vertical lathe workbench is installed in the gantry workbench. The vertical lathe function is realized by using the moving gantry as the vertical lathe frame and operating mechanism. The upper and lower raceways of the large slewing bearing 9 are respectively fixed on the workbench 1 and the base 2. Supported by rolling elements. The main motor adopts frequency conversion and speed regulation motor, and a rotary indexing system is added. The main reducer 5 is fixed on the side wall of the base 2, the frequency conversion motor 6 is connected with the main reducer 5 and drives the main reducer 5 to rotate, and the main reducer 5 transmits the speed and torque to the ring gear through the meshing of the gear and the ring gear 8 8. The ring gear 8 is fixed on the bottom of the table 1, the main shaft 3 is matched with the base 2 and the main shaft 3 is connected with the work table 1. The upper and lower parts of the large slewing bearing 9 are fixed on the base 2 and the workbench 1 respectively. Therefore, the ring gear 8 transmits the rotational speed and torque to the worktable 1, and the worktable rotates at a certain rotational speed. When the workbench 1 needs indexing, the frequency conversion speed regulation motor 6 is stopped, the main reducer 5 is turned to the highest gear, the indexing mechanism 4 drives the indexing gear 7 to rotate, and the indexing gear 7 drives the ring gear 8 to rotate. Thus, the workbench is indexed, and the accuracy of indexing is greatly improved.
