[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] 1. For the quenching device for processing tapered roller bearings that facilitates material taking, by setting the rotating shaft, main bevel gear, secondary bevel gear, connecting rod, semi-gear block, rack and special-shaped rod, by starting the motor to rotate the rotating shaft, the connecting rod is driven to rotate by the meshing of the main bevel gear and the secondary bevel gear, and through the cooperation of the main synchronous pulley, synchronous belt and secondary synchronous pulley, the two semi-gear blocks push the rack to slide, thereby pushing the high-frequency quenching device and the special-shaped rod to move.

Specific embodiments
[0021] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments.
[0022] As Figures 1-5 shown, the present utility model provides a technical solution: a quenching device for processing tapered roller bearings that facilitates material taking, including a machine table 1, a water storage tank 2 is arranged on the machine table 1, two water replacement pipes 3 are installed on one side of the machine table 1, a quenching table 4 is connected to the machine table 1, a fixed rod 5 is connected to the machine table 1, a collection box 6 is installed on the fixed rod 5, a hook plate 601 is connected to the collection box 6, water filter ports 602 are opened on both sides and the bottom of the collection box 6, the hook plate 601 is hooked on the fixed rod 5, and through the water filter ports 602, the water in the water storage tank 2 can flow into the collection box 6, so as to cool the falling bearing rings, and when the staff moves the collection box 6, the water will also filter out from the water filter ports 602, and the water storage tank 2 is drained and filled respectively through the two water replacement pipes 3, so as to timely replace the cooling water and avoid the temperature rise of the water during long-term use affecting the cooling efficiency.
[0023] A motor 7 is installed inside the quenching table 4, the output shaft of the motor 7 is connected to a rotating shaft 8, one end of the rotating shaft 8 is connected to a turntable 19, and a plurality of fixed tables 20 are installed on the turntable 19. The rotating shaft 8 is rotatably connected to the quenching table 4. The fixed tables 20 are four in total and are evenly distributed in a centrosymmetric manner. Through the plurality of fixed tables 20 on the turntable 19, the staff can complete the processes of loading, unloading and heating when the turntable 19 rotates, thereby improving the efficiency of bearing quenching processing.
[0024] A main bevel gear 9 is connected to a rotating shaft 8. A secondary bevel gear 10 is meshed with the main bevel gear 9. A connecting rod 11 is connected to the secondary bevel gear 10. A chute 21 is formed on a fixed table 20. A slider 22 is slidably connected in the chute 21. A tensioning plate 23 is connected to the slider 22. One side of the tensioning plate 23 is provided with an inclined surface and the center position is recessed inward. When the tensioning plate 23 tensioningly fixes the bearing race, the race will be caught in the recess at the middle position of the tensioning plate 23, so that a certain interval is generated between the race and the fixed table 20, facilitating the pushing of the race by the special-shaped rod 18. The moving race can push the tensioning plate 23 to move through the inclined surface on one side of the tensioning plate 23, facilitating feeding and discharging.
[0025] The slider 22 is designed in a T shape and springs 24 are connected to both sides. One end of each spring 24 is connected to the inner wall of the chute 21. Through the sliding of the T-shaped slider 22 in the chute 21, the tensioning plate 23 can move smoothly. When moving, the springs 24 will deform, and the tensioning plate 23 is fixed to the race by the elastic force of the springs 24 to prevent the race from accidentally falling off.
[0026] One end of the connecting rod 11 is connected to a main synchronous pulley 12. A synchronous belt 13 is connected to the main synchronous pulley 12. The main synchronous pulley 12 is connected to a secondary synchronous pulley 14 through the synchronous belt 13. Half gear blocks 15 are connected to both the lower part of the secondary synchronous pulley 14 and the connecting rod 11. The half gear blocks 15 are meshed with a rack 16. One end of the rack 16 is connected to a high-frequency quenching device 17. The high-frequency quenching device 17 is connected to a special-shaped rod 18 below. The half gear block 15 connected to the lower part of the secondary synchronous pulley 14 is rotatably connected above a quenching table 4. A T-shaped plate bar is connected to the lower part of the rack 16. The rack 16 is slidably connected to the quenching table 4 through the T-shaped plate bar.

The T-shaped plate bar below the rack 16 can make the rack 16 move smoothly.
[0027] The working principle of the present utility model is as follows:
[0028] The operator inserts the tensioning plate 23 into the inner diameter of the bearing ring. As the tensioning plate 23 is inserted, the ring will push and squeeze the tensioning plate 23, causing the slider 22 to slide within the sliding groove 21 and deforming the spring 24. Thus, through the resilience of the spring 24, the tensioning plate 23 is tightened to fix the ring. Then, the motor 7 is started to rotate the rotating shaft 8, causing the turntable 19 to start rotating. As the rotating shaft 8 rotates, the main bevel gear 9 will drive the connecting rod 11 to rotate through the secondary bevel gear 10. At this time, the half-gear block 15 on the connecting rod 11 will push the rack 16, moving the high-frequency quencher 17 away from the fixed table 20. The main synchronous pulley 12 will drive the secondary synchronous pulley 14 through the synchronous belt 13 to rotate another half-gear block 15, thereby pushing the rack 16 in the reverse direction, enabling the high-frequency quencher 17 to heat the ring. Then, the turntable 19 continues to rotate. After the turntable 19 rotates 90°, the special-shaped rod 18 completes the reciprocating movement and fits with the fixed table 20. Thus, by the half-gear block 15 pushing the rack 16, the special-shaped rod 18 pushes the ring off the fixed table 20, causing the heated ring to fall into the collection box 6. Thus, the quenching work is completed through the cooling of the water in the water storage tank 2.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.
[0030] The above has described the preferred embodiments of this patent in detail, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of this patent.
