Problems solved by technology

[0002] The turntable used for bearing, especially the strong bearing turntable, has a large diameter and thin wall, complex structure, and high requirements for workpiece surface and position accuracy. In addition, the parallelism of the turntable is required to be high, otherwise it will easily cause loud noise during work. Therefore, the selection of blanks and the processing of holes and grooves must be precise, and the consistency of related parts during processing, especially the center The position of the hole, the central hole between the small holes, and the coaxiality are very demanding, which directly affects the quality of the turntable.
In the general processing technology, the raceway inspection needs two people to cooperate at the beginning, which wastes human resources, the measurement efficiency is low, and the detection is inaccurate; after the trial assembly, if the two kinds of balls are easy to mix together, it is necessary to rely on a ruler to measure them one by one. out, wasted a lot of time

Embodiment Construction

[0026] In this embodiment, the processing technology of the turntable includes the processing technology of the moving ring of the turntable and the processing technology of the fixed ring of the turntable,

[0027] a. Moving coil processing:

[0028] a1. Pretreatment: use forging or casting to process the blank; fix the blank with a fixture, drill the center hole and bore to the required size and turn the outer circle, reserve a machining allowance of 10-12mm, remove sharp edges and burrs, and the overall surface roughness reaches Ra12.5; after ultrasonic flaw detection treatment, it is quenched and tempered to a hardness of HRC32-38, and then semi-finishing turning is performed;

[0029] a2. Artificial aging: heat the moving coil blank to 550-650°C for annealing, and keep the temperature at 160-220°C for 10-14 hours;

[0030] a3. Finishing, fix the blank on the special tooling first, and then put it on the lathe, the chuck of the lathe clamps the tooling that fixes the blan...

Abstract

The invention relates to a processing technology of a turntable used for bearing. The turntable is prevented from suffering phenomena such as distortion and out-of-roundness during processing, and the parallelism and the axiality of the turntable are enhanced, and meanwhile, the efficiency of raceway detection is improved during the processing process. Cooperatively rotating with parts, the processed turntable is more fit for equipment and work pieces needing super bearing capacity. In use, the turntable generates weak noises.
