DETAILED DESCRIPTION

[0022] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Combined with reference Figure 1-Figure 5 The utility model provides a surface hardness treatment device for a bearing rolling element, comprising a liquid storage tank 1, in which cooling water for quenching and cooling the bearing rolling element can be arranged, a pair of rotating supports 2 are fixedly connected to the liquid storage tank 1, a rotating support rod 3 is rotatably connected to the pair of rotating supports 2, a pair of supporting plates 4 are fixedly connected to the rotating support rod 3, a rotating motor 5 for driving the rotating support rod 3 to rotate is arranged on one of the rotating supports 2, the rotating motor 5 is connected to the rotating support rod 3 through a coupling, at least two pairs of loading and discharging structures 6 for placing the bearing rolling element are arranged between the pair of supporting plates 4, each loading and discharging structure 6 comprises a storage box 61 and a drainage hole 62 opened on the storage box 61, and the arrangement of the drainage hole 62 can ensure that the water is kept dry when the storage box 61 is immersed in the water of the liquid storage tank 1. Effectively enter the storage box 61 to cool the bearing rolling elements. In the present application, the round bearing rolling elements can be preferably quenched and cooled in the storage box 61 to improve the surface hardness. Secondly, the spherical bearing rolling elements can be quenched and cooled. Both ends of the storage box 61 are provided with load-bearing rotating parts 7. The storage box 61 is rotatably connected to the support plate 4 through the load-bearing rotating parts 7. The two pairs of load-bearing rotating parts 7 on the same side are provided with rotating gears 8. The liquid reservoir 1 is provided with a driven transmission structure 9 for contacting and engaging one of the rotating gears 8. A pair of guide sliding frames 10 are fixedly mounted on one side of the liquid reservoir 1. A discharge plate 11 is slidably connected to the pair of guide sliding frames 10. A hydraulic device 12 is hinged on the discharge plate 11 and the liquid reservoir 1. In the present application, the hydraulic device 12 can adopt a hydraulic rod.

[0024] The load-bearing rotating member 7 includes a hanging plate 71 fixedly connected to one side of the upper surface of the storage box 61 and a shaft rod 72 fixedly connected to the hanging plate 71, and the shaft rod 72 is rotatably connected to the support plate 4. The advantage of such a design is that when the storage box 61 is set between a pair of support plates 4, because the rotation fulcrum of the shaft rod 72 is located above the storage box 61, under the action of the gravity of the storage box 61, when the support plate 4 rotates, the storage box 61 can be guaranteed to be vertically set in real time, effectively avoiding the falling of the bearing rolling elements caused by overturning.

[0025] The rotating gear 8 is fixedly connected to one end of the shaft rod 72 , and one end of the shaft rod 72 extends to the side position of the support plate 4 , so the rotating gear 8 is arranged at the side position of the support plate 4 .

[0026] The driven transmission structure 9 includes a fixed arm 91 fixedly connected to the top of the liquid storage tank 1 and an annular rack 92 fixedly connected to the fixed arm 91 . The annular rack 92 is in contact and meshing with one of the rotating gears 8 .

[0027] Specifically, the bearing rolling elements are manually loaded into the storage box 61 on one side of the liquid reservoir 1, and the rotating motor 5 is started to run at a low speed, which can drive the support plate 4 to rotate. The rotation of the support plate 4 can drive multiple storage boxes 61 to enter the liquid reservoir 1 in sequence. Since the rotation fulcrum of the shaft rod 72 is located above the storage box 61, under the action of the gravity of the storage box 61, the storage box 61 can ensure the vertical setting in real time when the support plate 4 rotates, so that the bearing rolling elements can be effectively quenched and cooled, thereby improving the surface hardness, until one of the rotating gears 8 is close to the position of the annular rack 92 and contacts and engages, the rotating gear 8 can synchronously drive the hanging plate 71 and the storage box 61 to rotate, and at this time, the area of ​​the storage box 61 is the unloading area.

[0028] A liquid hole is opened on the unloading plate 11, and the liquid hole can conveniently discharge the cooling water falling on the bearing rolling body, and a sponge board 13 is fixedly connected to the upper surface of the unloading plate 11. The position of the sponge board 13 is set, when the storage box 61 rotates to discharge the bearing rolling body inside, the bearing rolling body falling on the sponge board 13 can be buffered. At the same time, the water absorption of the sponge board 13 can absorb the cooling water attached to the bearing rolling body, and the loss of cooling water can be reduced while ensuring a certain degree of cleanliness of the bearing rolling body when unloading.

[0029] Specifically, when the storage box 61 rotates to the top of the end of the unloading plate 11 through the support plate 4, the contraction of the piston of the hydraulic device 12 can drive the unloading plate 11 to slide in the guide frame 10, so that the unloading plate 11 can effectively correspond to the lower position of the storage box 61 to perfectly receive the bearing rolling body, thereby ensuring the reliability of the unloading of the bearing rolling body. Subsequently, the unloading plate 11 can be controlled to move away by extending the piston of the hydraulic device 12, thereby ensuring the follow-up of the subsequent storage box 61.

[0030] It is worth noting that when the blanking plate 11 is used to receive the bearing rolling elements, in order to prevent the bearing rolling elements from falling off the sides of the blanking plate 11 , baffles may be installed on both sides of the blanking plate 11 to achieve a containment effect.

[0031] A collecting box 14 is provided at the bottom of the blanking plate 11. The collecting box 14 can be used to receive the cooling water falling out of the liquid hole of the blanking plate 11, so as to improve the utilization rate of the cooling water.
