Description

Technical Field

[0001] This utility model relates to the field of bearing ring processing technology, specifically to an isothermal salt bath martensitic quenching device for bearing rings. Background Technology

[0002] Bearing rings are annular parts of radial rolling bearings with one or more raceways. A prior patent, CN221626320U, describes a bearing ring quenching device. It includes a quenching chamber, a fixed base fixedly connected to the upper surface of the chamber, a bracket fixedly connected to the upper surface of the fixed base, a motor fixedly connected to the upper surface of the bracket, a crank fixedly connected to the output end of the motor, a connecting rod rotatably connected to the side wall of the crank, a connecting rod rotatably connected to the side wall of the connecting rod, a sliding sleeve fixedly connected to the upper surface of the fixed base, a sliding rod slidably connected inside the sliding sleeve, and the upper surface of the sliding rod fixedly connected to the side wall of the connecting rod. In this invention, the bearing rings to be quenched are placed on a placement tray, and then the motor is started to rotate the crank, which in turn moves the connecting rod. As the connecting rod rotates on the crank, it moves the sliding rod up and down, thus moving the placement tray within the quenching chamber, improving the efficiency of quenching the bearing rings.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: during salt bath quenching, the salt particles in the water tend to sink to the bottom and fail to dissolve completely when left for a long time, which affects the quenching effect. Therefore, we propose an isothermal salt bath martensitic quenching device for bearing rings to solve the above-mentioned problems. Utility Model Content

[0012] This invention provides an isothermal salt bath martensitic quenching device for bearing rings. Compared with the prior art, it has the following advantages:

[0013] This isothermal salt bath martensitic quenching device for bearing rings features a connecting frame fixedly attached to the outside of a movable frame, with a wire basket fixedly connected to the inside of the connecting frame.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 This utility model provides a technical solution: an isothermal salt bath martensitic quenching device for bearing rings, including a quenching pool 1. The main body of the quenching pool 1 is a box structure with a one-way opening at the top. A drain pipe 101 is fixedly connected to the front end of the quenching pool 1. The drain pipe 101 has a two-way through structure on both the front and rear sides. An electromagnetic valve is installed inside the drain pipe 101. A connecting plate 102 is fixedly connected to the inner side of the quenching pool 1. The connecting plate 102 is arranged horizontally. There are two connecting plates 102. A base plate 103 is also fixedly connected to the inner side of the two connecting plates 102. A servo motor 104 is installed at the top of the base plate 103.

[0024] By fixing a base plate 103 to the inside of the connecting plate 102, it can support the servo motor 104 during use.

[0025] See Figure 1 , Figure 5 The connecting plate 102 and the base plate 103 together form a support structure for the servo motor 104, and the bottom end of the servo motor 104 is provided with an output shaft.

[0026] By mounting a servo motor 104 on the top surface of the base plate 103, it can provide stable power output during use.

[0027] See Figure 3 , Figure 5 A mixing component 105 is mounted on the bottom output shaft of the servo motor 104. The servo motor 104 and the mixing component 105 together form a mixing structure for the brine.

[0028] By installing a mixing component 105 on the bottom output shaft of the servo motor 104, the mixing of the water inside the quenching tank 1 can be accelerated during use.

[0029] See Figure 1 , Figure 5 A guide rail 2 is fixedly connected to the top surface of the base plate 103. The guide rail 2 is arranged longitudinally, and a longitudinal groove is opened inside the guide rail 2.

[0030] By fixing a guide rail 2 to the top surface of the base plate 103, the servo push rod 201 can be guided and installed during use.

[0031] See Figure 2 , Figure 4 A servo push rod 201 is fixedly connected inside the longitudinal groove opened in the guide rail 2. The main body of the servo push rod 201 is arranged longitudinally.

[0032] By fixing a servo push rod 201 inside the guide rail 2, it can provide stable power output during use.

[0033] See Figure 1 , Figure 2 A movable frame 202 is fixedly connected to the top surface of the servo push rod 201. The main body of the movable frame 202 is arranged longitudinally, and a slider 203 is fixedly connected to the outer side of the movable frame 202.

[0034] By fixing a movable frame 202 to the top surface of the servo push rod 201, it can be guided and slid by the slider 203 during use.

[0035] See Figure 3 , Figure 5 There are two sliders 203. The two sliders 203 are fixedly connected to the left and right sides of the movable frame 202 in opposite directions. A U-shaped connecting frame 3 is fixedly connected to the outside of the movable frame 202. A net basket 301 is fixedly connected to the inside of the connecting frame 3. The bottom surface of the net basket 301 has a rectangular array of mesh holes 302.

[0036] By providing a rectangular array of mesh holes 302 on the inner bottom surface of the basket 301, it can achieve rapid water filtration during use.

[0037] During operation, when the bearing ring is being quenched, water and salt are added to the quenching tank 1 in a certain proportion. The servo motor 104 installed on the top surface of the base plate 103 is started to drive the mixing component 105 to rotate. The rotation of the mixing component 105 continuously stirs the brine mixture inside the quenching tank 1 to prevent it from settling to the bottom.

[0038] At this point, the workpiece that needs to be quenched is placed inside the basket 301, and the servo push rod 201 installed in the guide rail 2 is activated to pull the moving frame 202 downward. The moving frame 202 can move downward along the guide rail 2 under the guidance of the slider 203 fixedly connected to its outer surface, and the connecting frame 3 drives the basket 301 to be immersed in the brine for continuous quenching, thereby achieving a more practical purpose.

[0039] In summary, the device, by having mesh openings 302 in the basket 301, enables the discharge of water from the basket 301 during use.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
