Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing equipment, in particular to a bearing outer ring annealing tool. Background Art

[0002] The hardness of the stamped outer ring of the bearing is relatively high after heat treatment, and the stamped outer ring needs to be annealed by high-frequency heating to reduce the hardness. Annealing is a metal heat treatment process that heats the metal to a certain temperature, keeps it for a sufficient time, and then cools it at an appropriate speed (usually slow cooling, sometimes controlled cooling).

[0003] The prior art discloses a bearing outer ring annealing tool with publication number CN214991744U, comprising an annealing box and a bearing outer ring, wherein an openable and closable transparent window is arranged on one side of the annealing box, an installation groove is arranged inside the annealing box, a support platform is arranged at the opening of the upper end of the installation groove, a motor is fixedly installed inside the installation groove, a turntable is arranged at the top end of the driving shaft of the motor, the turntable is arranged on the upper end surface of the support platform, a support plate is arranged on the upper surface of the turntable, the bearing outer ring is arranged on the upper surface of the support plate, and a first burner and a second burner are arranged on both sides of the upper end of the bearing outer ring of the annealing box, and a first nozzle and a second nozzle are arranged on one side of the first burner and the second burner, respectively.

[0004] When the above-mentioned device is in use, the outer ring of the bearing is sleeved between the first fixing rod and the second fixing rod. The fixing stability of the outer ring of the bearing is low during the rotation of the motor. At the same time, when the outer ring of the bearing is heated, the second fixing rod attached to the outer wall of the outer ring of the bearing also affects the heating of the outer ring of the bearing, resulting in uneven heating of the outer ring of the bearing.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-2 As shown, the bearing outer ring annealing tool of this embodiment includes a shell 1, a heating device 2 and a support leg 3. A motor 4 is installed at the bottom of the inner cavity of the shell 1, and a heat insulation board 5 is installed above the motor 4. The heat insulation board 5 can separate the upper and lower parts of the inner cavity of the shell 1 to reduce the high temperature borne by the motor 4. The output shaft of the motor 4 passes through the partition and a rotating seat 6 is fixedly installed at one end. The outer ring of the bearing is placed on the rotating seat 6, and the rotating seat 6 drives the outer ring of the bearing to rotate and heat. A slot 7 is opened in the middle of the rotating seat 6, and a hydraulic cylinder 8 is fixedly installed at the top of the inner cavity of the shell 1. A lifting block 9 is installed at one end of the bottom of the hydraulic cylinder 8 through a bearing. The lifting block 9 is used in conjunction with the slot 7. When the lifting block 9 descends, it can resist the inner wall of the outer ring of the bearing and fix the outer ring of the bearing on the rotating seat 6.

[0029] Working principle: open the switch door 11, place the outer ring of the bearing in the middle of the rotating seat 6, and when the hydraulic cylinder 8 drives the lifting block 9 to descend, the lifting block 9 with a conical structure at the bottom presses against the inner wall of the outer ring of the bearing, and presses the outer ring of the bearing onto the rotating seat 6, while realizing automatic centering of the outer ring of the bearing. When the motor 4 is working, it drives the rotating seat 6 to rotate, and the rotating rotating seat 6 cooperates with the heating device 2 to rotate and heat the outer ring of the bearing on the rotating seat 6.
