Problems solved by technology
This method uses multiple extensions and retractions of the hydraulic cylinder, the movement is slow, and in the process of turning over, it needs to cooperate with the loading and unloading and turning of the external sling, and the action is cumbersome, which will make the turning time of the workpiece longer. low efficiency
Similarly, the turning device is also a fixed device, which not only occupies a large area, but also cannot accompany the workpiece in the processing process, and cannot meet the requirements of the ring gear turning over multiple times during the processing process.

The invention discloses a turning-over device and method for a tooth ring of a rotation bearing and belongs to the technical field of machining. The turning-over device for the tooth ring of the rotation bearing is used for achieving turning-over of the tooth ring and the like of the large-sized rotation bearing in multiple machining procedures. The turning-over device for the tooth ring of the rotation bearing comprises a lifting system, a control system, a workpiece clamp system and a protective system. According to the turning-over device, two lifters are installed on a cross beam, and the workpiece is turned over through paying off and taking up of lifting ropes between the two lifters. The turning-over device and method for the tooth ring of the rotation bearing have the technological advantages of achieving simple assembly, small deformation, high turning-over efficiency and the like and has huge potential market application prospect.
Description
Technical field: [0001] The device of the invention belongs to the technical field of mechanical processing, and in particular relates to a device and method for turning over a slewing bearing ring gear, which are used to realize turning over of a slewing bearing ring gear and the like in different working procedures. Background technique: [0002] The slewing bearing is an important supporting and transmission element necessary for relative rotary motion between two parts, and at the same time it needs to bear axial force, radial force and tipping moment, also called slewing bearing. It is widely used in modern industry, such as radar in military equipment, concrete pump truck in construction machinery, tower crane in port machinery, ladle rotary table in metallurgical equipment, wind power generation equipment in new energy equipment Wait. It is usually composed of ring gear, seat ring and rolling elements. After the blank of the ring gear is processed by forging, rough t...
