Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, in particular to a quenching device for producing cylindrical roller bearing rings. Background Art

[0002] Bearing rings are subject to complex stresses such as tension, compression, shear, and alternating stresses during bearing operation, and the stress values are relatively large. This requires that bearing rings must have high hardness, high wear resistance, and certain impact toughness and fracture toughness. Quenching is a key process to improve the performance of bearing rings. Quenching can change their organizational structure to meet the requirements of use.

[0017] The present invention proposes a quenching device for producing cylindrical roller bearing rings. Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The quenching device for the production of cylindrical roller bearing rings is provided with a first thread groove and a first thread column. By turning on the first motor, the hollow drum can be driven to rotate. Since the first thread column cannot rotate, the rotation of the hollow drum can make the first thread column move up and down, indirectly driving the hollow lifting column to move up and down. During the lifting process of the hollow lifting column, the movable plate can be moved, and the movement of the movable plate can make the positioning plate slide through the first slider and the first slide rail. The relative movement of the four groups of positioning plates can quickly position and fix the bearing ring module from the inside, avoiding the problem that most quenching devices for the production of bearing rings use simple fixing devices to directly perform fixed quenching. Due to the lack of a positioning fixing component, the bearing ring cannot be in the exact center position, and uneven heating will occur during the quenching process.

[0019] 2. The quenching device for producing cylindrical roller bearing rings is provided with a first bevel gear and a second bevel gear. By turning on the second motor, the fourth rotating shaft and the half bevel gear can be driven to rotate. Since the tooth block on the outer side of the half bevel gear is not a full circle, when one side of the tooth block is respectively engaged with the first bevel gear or the second bevel gear, it will drive the first bevel gear to rotate forward or the second bevel gear to rotate reversely, thereby realizing the forward and reverse rotation of the same connecting column under different structural engagement conditions, thereby realizing automatic flipping of the clamping assembly, making it convenient to take and place the bearing ring module;

[0020] 3. The quenching device for the production of cylindrical roller bearing rings is provided with a second threaded column and a second threaded groove. By turning on the third motor, the second threaded column can be driven to rotate. Through the threaded connection between the second threaded column and the second threaded groove, the rotation of the second threaded column can move the brake plate. The movement of the brake plate can cause the two sets of movable plates to move relative to each other through the second slider and the second slide rail, indirectly driving the relative movement of the two sets of clamping plates to achieve a clamping effect, so as to clamp and fix the bearing ring module so that it can be taken and placed again;

[0021] 4. The quenching device for the production of cylindrical roller bearing rings is equipped with a water spray end and a heating pipe. The lifting frame can be driven up and down by the extension and contraction of the hydraulic rod, and the water spray end and the heating pipe can be raised and lowered during the lifting process of the lifting frame. The setting of multiple sets of heating pipes can directly heat the bearing ring module to red, and then spray water through the water spray end to cool it down to achieve the quenching effect.
