[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] The front, rear, left, right, up, and down in this embodiment are described with Figure 1 as the reference plane. Please refer to Figures 1-6 , the present utility model provides a technical solution:
[0021] A quenching device for bushing production, including a processing table 1. A cold water tank 11 is opened on the left side of the upper surface of the processing table 1. Two tracks 2 are fixedly installed at the upper end opening of the cold water tank 11. The right ends of the tracks 2 extend to the right end of the upper surface of the processing table 1. An automatically traveling movable carrier plate 3 is slidably installed between the two tracks 2. A plurality of inverted convex-shaped placement grooves 31 are equidistantly penetrated through the upper surface of the movable carrier plate 3. A support plate 6 is fixedly installed on the upper surface of the processing table 1. A heating induction coil body 61 and a pushing device 7 are fixedly installed on the front surface of the support plate 6. The heating induction coil body 61 is arranged in parallel above the inverted convex-shaped placement groove 31. A lifting device 8 is fixedly installed in the cold water tank 11. The lifting device 8 is located directly below the heating induction coil body 61;
[0022] During the bearing quenching operation, the bearing to be quenched can be placed in the inverted convex-shaped placement groove 31 of the movable carrier plate 3 at a position on the right side of the processing table 1 away from the quenching heating area. Through the linkage cooperation of the walking motor 4, the gear 41 and the rack 5, the movable carrier plate 3 and the bearing are transported below the heating induction coil body 61. Then, with the help of the lifting device 8, the bushing in the inverted convex-shaped placement groove 31 is lifted into the heating induction coil body 61 for heating. After heating, the bearing is lowered by the lifting device 8 in front of the pushing device 7, and then the pushing device 7 is used to push the bearing from the top of the lifting device 8 into the cold water tank 11 for cooling, completing the quenching operation of a single bearing. After that, relying on the movable carrier plate 3, the bearings on the right side can be quenched in the above operation mode in sequence;
[0023] The entire operation process can be achieved by mechanical equipment throughout, and there is no need to load materials near the heating area. While improving the efficiency, it can also ensure the safety of the loading personnel, effectively solving the problems of low production efficiency and certain safety hazards in the existing bearing quenching operation.
[0024] In some advanced manufacturing enterprises, using this automated bushing quenching device can significantly increase the production rhythm, reduce manual intervention, and thus reduce the defective rate. Moreover, since it avoids personnel working in high-temperature dangerous areas, it greatly reduces the incidence of work-related injuries and saves a large amount of safety costs for the enterprise.
[0025] Specifically, as Figure 3 shown, an L-shaped carrier 12 is fixedly installed in the cold water tank 11. The lifting device 8 includes an electric telescopic rod 81 fixedly installed on the L-shaped carrier 12. The top of the electric telescopic rod 81 is fixedly installed with a support plate 82 (the support plate 82 is slightly smaller than the lower opening of the inverted convex-shaped placement groove 31 and larger than the lower opening of the bearing). The support plate 82 is arranged parallel to the lower part of the inverted convex-shaped placement groove 31. The telescopic movement of the electric telescopic rod 81 can drive the support plate 82 to move up and down, so as to use the support plate 82 to penetrate the corresponding inverted convex-shaped placement groove 31 to lift and move the bearing in the movable carrier plate 3.
[0026] Specifically, as Figure 3 shown, the pushing device 7 includes a pneumatic telescopic rod 71 fixedly installed on the front surface of the support plate 6. The telescopic end of the pneumatic telescopic rod 71 is fixedly installed with a push plate 72. The push plate 72 is arranged parallel to the lower part of the heating induction coil body 61. The rapid extension of the pneumatic telescopic rod 71 can push the bearing in front of the push plate 72 away from the support plate 82, so that it falls into the cold water tank 11 for cooling. The extension speed of the pneumatic telescopic rod 71 needs to be debugged before use to make it push the bearing just into the cold water tank 11 at an appropriate extension speed.
[0027] Specifically, combining Figure 5 andFigure 2 As shown, an L-shaped fixing block 32 is fixedly installed on the upper surface of the movable carrier plate 3. A traveling motor 4 is fixedly installed on the rear surface of the L-shaped fixing block 32. A gear 41 is sleeved on the outer surface of the output shaft of the traveling motor 4. A rack 5 is fixedly installed on the rear surface of the rear-end track 2. The rack 5 is meshed with the gear 41. The traveling motor 4 drives the gear 41 to rotate, and the cooperation of the rack 5 and the gear 41 drives the movable carrier plate 3 to slide between the two tracks 2, so as to transfer the bearing below the heating induction coil main body 61. When the traveling motor 4 is in use, it is necessary to closely adjust the traveling speed and frequency of the traveling motor 4 with the help of an external programming controller to ensure that the bearing can be moved below the heating induction coil main body 61 each time, so as to facilitate the lifting by the lifting device 8.
[0028] Specifically, as shown in Figure 4 and Figure 5 both opposite surfaces of the two tracks 2 are provided with sliding grooves 21. Sliders 33 are fixedly installed on the front and rear surfaces of the movable carrier plate 3. The sliders 33 are slidably installed in the corresponding sliding grooves 21. The movable carrier plate 3 is slidably installed between the two tracks 2 through the cooperation of the sliders 33 and the sliding grooves 21.
[0029] Finally, it should be noted that the traveling motor 4, the electric telescopic rod 81, the pneumatic telescopic rod 71 and the heating induction coil main body 61 are all electrically connected to an external controller. The external controller can be a control structure such as a computer or a single-chip microcomputer. The action strokes of the traveling motor 4, the electric telescopic rod 81, the pneumatic telescopic rod 71 and the heating induction coil main body 61 can all be accurately positioned by a laser locator or an infrared locator, etc. After the action information is fed back to the external controller, the actions are sequentially controlled by the external controller. This control method is a mature application of the prior art and will not be elaborated here.
