Abstract

The invention relates to auxiliary support devices for a large rotation work table. The devices are distributed on the periphery of the work table uniformly. Each device comprises a support element, a roller mounting seat, a roller and a base. The roller mounting seats are arranged at the tops of the supporting elements, the bases are arranged at the bottoms of the support elements, the rollers are arranged on the roller mounting seats, rolling shafts of the rollers are parallel to the plane of the work table, and the bases are fixed on the ground through tightening bolts. The devices have the advantages that the auxiliary support devices are arranged on the periphery of the bottom of the large rotation work table, so that the rigidity and the stability of the large rotation work table can be increased, and the pressure and the overturning force to the machine tool table are reduced. The devices are high in bearing capacity and stability, convenient to correct and high in accuracy.

Description

technical field [0001] The invention relates to an auxiliary supporting device for a large rotary table. Background technique [0002] For large gear hobbing machines, when processing large parts, due to the limited diameter of the table, it is necessary to install a rotary table, but the structure and rigidity of many large-diameter large rotary tables are not good, especially after being expanded by horse legs, the vibration is relatively large. Large, the stability is not good, the cutting speed is greatly reduced, and the accuracy is difficult to guarantee. Then the diameter of the rotary table is enlarged, and the weight of the rotary table is continuously increased in order to make the structure more stable. Contents of the invention [0003] The technical problem to be solved by the present invention is: large-scale gear hobbing machine uses a rotary table to process large parts with large vibration, poor stability, greatly reduced cutting speed, and difficulty in ...
