Description

Technical Field

[0001] This utility model relates to the field of induction hardening technology, specifically a lifting and rotating turntable device for integral hardening of the inner and outer rings of large bearings. Background Technology

[0002] Large bearings play a crucial supporting role in various heavy machinery and equipment. Their main function is to bear radial and axial loads and reduce rotational friction through rolling contact. Because they operate under high load and high speed conditions, the inner and outer rings of the bearings must have high hardness and wear resistance to ensure long service life and high performance.

[0003] To meet the requirements for high hardness and high wear resistance, the inner and outer rings of large bearings are typically hardened. The hardening process alters the microstructure of the material through rapid heating and cooling, thereby significantly improving its hardness and wear resistance.

[0004] In existing technologies, large bearings are mostly hardened using scanning quenching. For machining large workpieces, the processing speed is too slow, and continuous uninterrupted quenching of large workpieces requires high-frequency power supplies to operate at full load for a long time, which can easily lead to equipment overheating and requires an additional cooling system. Bainitic integral quenching, compared with traditional quenching methods, requires slow cooling to the isothermal region at the critical cooling rate. It is easy for pearlite or martensite to be mixed in due to improper selection of cooling medium, which reduces the processing effect. For common integral quenching cooling methods, it is often necessary to manually inject quenching liquid into the quenching tank. However, the quenching tanks required for large workpieces are often deep and large, and manual water injection poses a significant safety risk. Utility Model Content

At the start of processing, the workpiece is mounted and fixed on the workpiece rotary table component. The rotary table lifting component drives the rotary table rotating component and the workpiece clamping component to move to the appropriate position. Once in the appropriate position, the locking mechanism of the rotary table lifting component locks the lifting slide column, fixing the position of the workpiece clamping component. After the heating component completes heating (during which the rotary table rotating component can rotate the workpiece), the locking mechanism of the rotary table lifting component retracts, causing the rotary table lifting component to lower the rotary table rotating component and the workpiece clamping component into the quenching water tank. The quenching water tank then quenches the workpiece. After quenching, the workpiece driving component moves the workpiece clamping component to the appropriate position to remove the workpiece, thus ending the quenching process.
