Description

Technical Field

[0001] The present application relates to the field of heat treatment equipment, and in particular to an environmentally friendly heat treatment equipment for processing a bearing seat. Background Art

[0002] Large bearings are widely used in modern industry. They include a raceway and an inner ring arranged in the inner hole of the raceway. The inner hole wall of the raceway is provided with an annular groove that matches the rolling element. The groove wall of the groove is the raceway surface of the raceway. The groove of the inner hole wall of the raceway is mostly an arc-shaped groove. The raceway surface of the arc-shaped groove can effectively fit the rolling element, which improves the working stability of large bearings. Because the raceway surface will be affected by the friction of the rolling element for a long time during use, it is necessary to perform surface quenching on the raceway surface of the large bearing raceway to improve the hardness and wear resistance of the raceway surface and extend the service life of the large bearing.

[0003] The Chinese utility model patent with publication number CN217104019U discloses an automated heat treatment device for large diameter bearings. Although it can be applied to the heat treatment of bearing races of different specifications, it has a relatively complex structure, cumbersome operation and high manufacturing cost.

[0016] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0017] The present application discloses an environmentally friendly heat treatment device for processing a bearing seat. Figure 1 and Figure 2 The equipment includes a base 1, a lifting platform 2 arranged on the base 1, a clamping mechanism 3 arranged on the lifting platform 2, a rotating mechanism 4 arranged on the base 1, and a high-frequency quenching head 6 arranged on the rotating mechanism 4.

[0018] The lifting platform 2 includes a guide rod 21 fixedly arranged on the base 1 , a bearing plate 22 slidably arranged on the guide rod 21 , and a hydraulic cylinder 23 fixedly arranged on the base 1 , wherein the piston rod of the hydraulic cylinder 23 abuts against the lower end surface of the bearing plate 22 .

[0019] There are at least two guide rods 21, which are respectively adjacent to the opposite sides of the bearing plate 22, and are used to guide the bearing plate 22. The hydraulic cylinder 23 is located at the center of gravity of the bearing plate 22, and is used to bear the weight of the bearing plate 22 and the bearing seat placed on the bearing plate 22. It is also used to adjust the height of the bearing plate 22 so that the center of the inner ring of the bearing seat placed on the bearing plate 22 is directly opposite to the center of the rotating mechanism 4, so that the rotating mechanism 4 can drive the high-frequency quenching head 6 to move accurately along the inner side of the bearing seat for heat treatment.

[0020] The clamping mechanism 3 includes a static clamping plate 31 and a dynamic clamping plate 32 arranged on the bearing plate 22, a fixing ear 33 is arranged on the bearing plate 22, and a spring telescopic rod 34 is arranged between the fixing ear 33 and the dynamic clamping plate 32. A handle 35 is arranged on the side of the dynamic clamping plate 32 away from the static clamping plate 31, which is used to pull the dynamic clamping plate 32 apart so as to place the bearing seat between the static clamping plate 31 and the dynamic clamping plate 32. When the handle 35 is released, the bearing seat can be clamped by the elastic action of the spring telescopic rod 34, and the inner ring of the bearing seat is exposed above the dynamic clamping plate 32, so as to perform heat treatment on the inner ring of the bearing seat.

[0021] The rotating mechanism 4 includes a support platform 41 disposed on the base 1, a motor 42 disposed on the support platform 41, a rotating rod 43 vertically disposed on the output shaft of the motor 42, and an adjusting block 5 slidably disposed on the rotating rod 43, and the high-frequency quenching head 6 is disposed on the adjusting block 5. The motor 42 is a low-speed motor 42, which is used to drive the high-frequency quenching head 6 to rotate, so that the high-frequency quenching head 6 can move slowly, so as to fully heat the position to be heat-treated on the bearing seat.

[0022] The adjusting block 5 includes a main clamping block 51 and an auxiliary clamping block 52. A screw rod 511 is vertically fixedly arranged in the middle position of the main clamping block 51. A through hole for passing the screw rod 511 is opened in the middle position of the auxiliary clamping block 52. The main clamping block 51 and the auxiliary clamping block 52 are respectively arranged on both sides of the rotating rod 43. A sliding hole 44 for passing the screw rod 511 is opened on the rotating rod 43. A butterfly nut 53 is threadedly connected to the screw rod 511.

[0023] The butterfly nut 53 abuts against the auxiliary clamping block 52. When the butterfly nut 53 is tightened, the auxiliary clamping block 52 and the main clamping block 51 clamp the rotating plate to fix the adjustment block 5. When the butterfly nut 53 is loosened, the auxiliary clamping block 52 and the main clamping block 51 loosen the rotating rod 43. At this time, the position of the adjustment block 5 on the rotating rod 43 can be adjusted according to the size of the bearing seat aperture. Thus, the effect of heat treatment of bearing seats with different apertures can be achieved with a relatively simple structure.
