Description

Technical Field

[0001] This utility model relates to the field of quenching technology, specifically a quenching device for bearing production. Background Technology

[0002] Quenching equipment is a key piece of equipment used in the bearing manufacturing process. Its main function is to rapidly and uniformly cool bearing parts to improve their hardness and wear resistance. By heating the bearing parts to a certain temperature, and then passing them through a cooling tank filled with a specific coolant, the parts are quenched immediately after heating. By precisely controlling the heating and cooling process, the quenching equipment can ensure that the bearing parts obtain the required microstructure and mechanical properties, thereby meeting their usage requirements under high load and high speed operating conditions.

[0003] However, existing quenching equipment for bearing production does not spray coolant evenly on the bearings, affecting the quenching effect of the equipment; therefore, it does not meet the current requirements. In response, we propose a quenching equipment for bearing production. Utility Model Content

[0004] The purpose of this invention is to provide a quenching device for bearing production, in order to solve the problems mentioned in the background art, such as the uneven spraying of coolant on the bearing by existing quenching devices for bearing production, which affects the quenching effect of the device.

The working chamber has an annular tube on its upper inner surface, a connecting rod on its inner side, a second connecting tube on its inner side, and spray heads evenly distributed on the outer surfaces of the annular tube and the second connecting tube. A placement plate is located on the outer side of the lower end of the connecting shaft, and a drive wheel is located on the outer surface of the connecting shaft inside the placement plate. Driven wheels are located on both sides of the drive wheel, and a connecting block is located inside the driven wheel. A positioning post is located on the upper surface of the connecting block. A liquid storage chamber is located below the working chamber, and a filter screen is installed between the working chamber and the liquid storage chamber.

A placement plate 15 is provided on the outer side of the lower end of the connecting shaft 11. A drive wheel 21 is provided on the outer surface of the connecting shaft 11 located inside the placement plate 15. Driven wheels 20 are provided on both sides of the drive wheel 21. A connecting block 19 is provided on the inner side of the driven wheel 20. A positioning column 16 is provided on the upper surface of the connecting block 19. A liquid storage chamber 23 is provided below the working chamber 14. A filter screen 22 is provided between the working chamber 14 and the liquid storage chamber 23.

[0017] Furthermore, the connecting block 19 is slidably connected to the placement plate 15, the driven wheel 20 is engaged with the driving wheel 21, and the connecting shaft 11 is slidably connected to the placement plate 15.

[0018] By adopting the above technical solution, the gear transmission of the connecting shaft 11 is facilitated, and the working stability of the connecting shaft 11 is improved. The rotation of the connecting shaft 11 drives the driven wheel 20 to rotate through the driving wheel 21, thereby driving the connecting block 19 and the positioning column 16 and the workpiece to rotate. The revolution of the connecting shaft 11 does not affect the meshing transmission between the driving wheel 21 and the driven wheel 20, because the placement plate 15 is slidably connected to the connecting shaft 11, and the placement plate 15 can move synchronously with the revolution of the connecting shaft 11.

[0019] Furthermore, a drive shaft is provided inside the sun gear 10, and a planet carrier is provided above the planet gear 9.

[0020] By adopting the above technical solution, the stability of the planetary gear transmission is increased and the transmission effect of the device is improved.

[0021] Furthermore, one side of the fixing plate 5 is completely attached to the outer surface of the main body 3, and the fixing plate 5 is fixed to the main body 3 by welding.

[0022] By adopting the above technical solution, the working strength of the fixing plate 5 is increased, and the supporting effect of the fixing plate 5 on the hydraulic cylinder 6 is improved.

[0023] Furthermore, a limiting plate is provided at the lower end of the connecting shaft 11, and an annular groove is provided on the upper surface of the limiting plate.

[0024] By adopting the above technical solution, the stability of the transmission of the connecting shaft 11 is increased, and the working effect of the device is improved.

[0025] Furthermore, the lower surface of the motor 1 is completely fitted with the upper surface of the cover plate 2, and the motor 1 and the cover plate 2 are fixed together by screws.

[0026] By adopting the above technical solution, the robustness of the motor 1 connection is increased, and the transmission effect of the motor 1 is improved.

[0027] Furthermore, the upper end of the connecting shaft 11 is fully fitted with the inner surface of the planetary gear 9, and the connecting shaft 11 and the planetary gear 9 are fixed by welding.

[0028] By adopting the above technical solution, the robustness of the connection of the connecting shaft 11 is increased, and the stability of the operation of the connecting shaft 11 is improved.

[0029] Working principle: In use, open the hydraulic cylinder 6 to push out the cover plate 2, and push out the placement plate 15 below the cover plate 2. Place the workpiece on the positioning column 16, and then close the cover plate 2. At this time, turn on the motor 1. Through the gear ring 8, planetary gear 9, sun gear 10 and connecting shaft 11 set on the inner side of the cover plate 2, the connecting shaft 11 inside the planetary gear 9 can rotate around the sun gear 10 while rotating on its own axis. When the connecting shaft 11 rotates, the driving wheel 21 set at the lower end of the connecting shaft 11 can be used to make the workpiece placed on the positioning column 16 above the connecting block 19 rotate continuously and stably. At the same time, through the connecting rod 17 inside the working chamber 14 and the annular pipe 12 set on the inner wall of the working chamber 14, and the spray head 13 set on the outer surface of the annular pipe 12 and the connecting rod 17, the workpiece can be evenly sprayed onto the outer surface of the workpiece, reducing the impact of uneven spraying on the quenching of the workpiece and improving the working effect of the device.
