According to the slewing bearing ferrule circular degree error automatic detection and correction device, the lifting and warping-resisting devices are adopted so that interferences between detection and correction and planar warping of the ferrule can be avoided, three eddy-current sensors are adopted in the circular degree error detection devices, the discretion fast Fourier transform is carried out on the collected signals so that the interferences of the eccentric errors of the slewing bearing ferrule can be eliminated, and the detection accuracy is improved.

Description

Technical field: [0001] The invention belongs to the technical field of industrial detection and correction, and in particular relates to an automatic detection and correction device for roundness errors of slewing rings, which is used for automatic detection and automatic correction of roundness errors of slewing rings. Background technique: [0002] During the manufacturing process of the slewing ring, the ring gear and the raceway are required to be surface quenched. After heat treatment, a large roundness error will be generated, which will seriously affect the performance of the slewing ring, and even fail to work normally. At present, there are mainly manual bench vise correction method and simple mechanical correction method. The traditional manual bench vise correction method has the following problems: low efficiency; manual pressurization by the operator, high labor intensity; no protective device, there are safety hazards and other problems. The problems of the s...

Problems solved by technology

The traditional manual bench vise correction method has the following problems: low efficiency; manual pressure by the operator, high labor intensity; no protection device, there are problems such as potential safety hazards

The problems of the simple mechanical correction method are as follows: 1. Generally, two points in the diameter direction are used to apply pressure correspondingly, which is easy to produce local unevenness, and the effect of improving the roundness error of the slewing bearing ring after correction is not ideal

2. There are stress concentration and stress offset problems during correction, which can easily cause fracture and warping deformation of the slewing bearing ring

3. The simple correcting equipment cannot automatically judge the correcting pressure application point and the correcting stroke of the pressure mechanism, and the operator needs to make a rough estimate based on experience, resulting in repeated corrections
