Description

A rapid cooling bearing quenching tank Technical Field

[0001] This utility model relates to the field of quenching tanks, specifically a bearing quenching tank for rapid cooling. Background Technology

[0002] Bearing quenching is one of the key heat treatment processes in bearing production. Its main purpose is to improve the hardness, wear resistance and fatigue strength of the material through quenching, so as to meet the requirements of bearings under high speed and heavy load conditions. The quenching process of bearings requires the use of a quenching tank for auxiliary operation.

[0003] However, current bearing quenching tanks still have some shortcomings. For example, existing bearing quenching tanks mostly use quenching oil directly for quenching, which causes impurities in the quenching oil, such as floating rust, iron filings, and carbon black, to adhere to the surface of the bearing, thus interfering with the subsequent processing of the bearing and resulting in certain defects in use.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is designed to address the deficiencies of the existing structure and provides a bearing quenching tank for rapid cooling.

[0005] Utility Model Content

[0006] The purpose of this invention is to provide a bearing quenching tank with rapid cooling to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling bearing quenching tank, comprising a quenching tank body and a bearing assembly. A bearing bracket is fixedly installed on the inner surface of the quenching tank body, and an impurity carrying box is fitted to the top of the bearing bracket. A fine filter screen is fixedly installed on the inner surface of the quenching tank body. Bearing plates are symmetrically fixedly connected to the front and rear sides of the quenching tank body, and an electric telescopic rod is installed on the top of the bearing plate. The bearing assembly is slidably connected to the inner surface of the quenching tank body. A fixed bracket is fixedly installed on the top of the quenching tank body, and a drive motor is installed on the side of the fixed bracket. A drive screw is installed on the output shaft of the drive motor through a coupling. A limit guide rod is fixedly installed on the inner surface of the fixed bracket, and a cleaning assembly is movably connected to the outer surface of the limit guide rod. A liquid pump is fixedly installed on the side of the quenching tank body.

[0008] Furthermore, the bottom of the impurity carrier box is fitted and connected to the top of the carrier support, and the outer surface of the carrier support is fixedly connected to the inner surface of the quenching tank.

[0009] Furthermore, the bearing assembly includes a bearing support frame, a T-shaped slide bar, and a connecting plate, with T-shaped slide bars symmetrically installed on the front and rear sides of the bearing support frame, and connecting plates symmetrically installed on the front and rear sides of the bearing support frame.

[0010] Furthermore, the side of the bearing support frame is fixedly connected to the inner side of the T-shaped slide bar, and the bearing support frame forms a sliding structure with the quenching tank through the T-shaped slide bar.

[0011] Furthermore, the end of the connecting plate is fixedly connected to the side of the bearing support frame, and the bottom of the connecting plate is fixedly connected to the top of the extension end of the electric telescopic rod.

[0012] Furthermore, the cleaning assembly includes a connecting seat, a fixing rod, a hollow fixing plate, a flushing nozzle, and an infusion tubing. The fixing rod is symmetrically installed at the bottom of the connecting seat, and the hollow fixing plate is fixedly connected to the bottom of the fixing rod. The flushing nozzle is fixedly installed at equal intervals at the bottom of the hollow fixing plate, and the infusion tubing is fixedly installed at the top of the hollow fixing plate. The interior of the connecting seat is movably connected to the side of the drive screw.

[0013] Furthermore, the top of the fixing rod is fixedly connected to the bottom of the connecting seat, and the bottom of the fixing rod is fixedly connected to the top of the hollow fixing plate, and the hollow fixing plate forms a fixed structure with the connecting seat through the fixing rod.

[0014] Furthermore, one end of the infusion tubing is fixedly connected to the top of the hollow fixing plate, and the other end of the infusion tubing is fixedly connected to the top of the pump.

[0015] This invention provides a rapid cooling bearing quenching tank, which has the following advantages:

[0016] 1. This utility model uses a drive screw to enable the drive motor to rotate the drive screw inside the fixed bracket during operation. Guided by the limit guide rod, the drive screw rotates and causes the cleaning component to move laterally along the top of the quenching tank. Then, the quenching liquid is sprayed onto the bearing in the bearing support frame through the operation of the flushing nozzle, thereby achieving the purpose of automatically flushing the quenched bearing. This avoids impurities in the quenching oil adhering to the bearing surface and interfering with subsequent processing of the bearing. Furthermore, the liquid delivery hose ensures that the cleaning component is not disturbed during movement.

[0017] 2. This utility model, through the installation of an electric telescopic rod, enables the bearing assembly to move stably up and down along the inner surface of the quenching tank during operation. This achieves the purpose of quickly moving the bearing into the quenching liquid for quenching and cooling. Furthermore, the impurity carrying box and fine filter screen ensure that the quenching liquid used for rinsing is fully filtered, thereby improving the rinsing cleanliness and preventing blockage of the pump and delivery hose. Impurities in the quenching liquid are also automatically collected inside the impurity carrying box for subsequent cleaning by the staff. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] As shown in Figures 1, 2, and 4, a rapid cooling bearing quenching tank includes a quenching tank body 1 and a bearing assembly 7. A fixed bracket 8 is fixedly installed on the top of the quenching tank body 1, and a drive motor 9 is installed on the side of the fixed bracket 8. The output shaft of the drive motor 9 is connected to a drive screw 10 via a coupling. A limit guide rod 11 is fixedly installed on the inner surface of the fixed bracket 8, and a cleaning assembly 12 is movably connected to the outer surface of the limit guide rod 11. The cleaning assembly 12 includes a connecting seat 121, a fixing rod 122, a hollow fixing plate 123, a flushing nozzle 124, and an infusion hose 125. Fixing rods 122 are symmetrically installed on the bottom of the connecting seat 121, and the bottom of the fixing rod 122 is fixedly connected to the hollow fixing plate 123. The top of the fixing rod 122 is fixedly connected to the bottom of the connecting seat 121, and the fixing rod 122... The bottom of 22 is fixedly connected to the top of the hollow fixed plate 123, and the hollow fixed plate 123 forms a fixed structure with the connecting seat 121 through the fixed rod 122. By setting the hollow fixed plate 123 and the connecting seat 121 into a fixed structure, the hollow fixed plate 123 will not loosen when the connecting seat 121 drives the hollow fixed plate 123 to move synchronously. Moreover, the bottom of the hollow fixed plate 123 is fixedly installed with flushing nozzles 124 at equal intervals, and the top of the hollow fixed plate 123 is fixedly installed with an infusion hose 125. The end of the infusion hose 125 is fixedly connected to the top of the hollow fixed plate 123, and the other end of the infusion hose 125 is fixedly connected to the top of the pump 13. The inside of the connecting seat 121 is adapted to be movably connected to the side of the drive screw 10. The side of the quenching tank 1 is fixedly installed with the pump 13.

[0025] As shown in Figures 1-3, a support bracket 2 is fixedly installed on the inner surface of the quenching tank 1, and an impurity carrier box 3 is fitted to the top of the support bracket 2. The bottom of the impurity carrier box 3 is fitted to the top of the support bracket 2, and the outer surface of the support bracket 2 is fixedly connected to the inner surface of the quenching tank 1. A fine filter screen 4 is fixedly installed on the inner surface of the quenching tank 1. Support plates 5 are symmetrically fixedly connected to the front and rear sides of the quenching tank 1, and an electric telescopic rod 6 is installed on the top of the support plate 5. A support assembly 7 is slidably connected to the inner surface of the quenching tank 1. The support assembly 7 includes a bearing support frame 71, a T-shaped slide bar 72, and a connecting plate 73. T-shaped slide bars 72 are symmetrically installed on the front and rear sides of the bearing support frame 71. The side of the bearing support frame 71 is fixedly connected to the inner side of the T-shaped slide bars 72. The bearing support frame 71 and the quenching tank 1 form a sliding structure through the T-shaped slide bars 72. By setting the bearing support frame 71 and the quenching tank 1 into a sliding structure, the bearing support frame 71 moves more smoothly and stably when it moves up and down along the inner surface of the quenching tank 1. Connecting plates 73 are symmetrically installed on the front and rear sides of the bearing support frame 71. The end of the connecting plate 73 is fixedly connected to the side of the bearing support frame 71, and the bottom of the connecting plate 73 is fixedly connected to the top of the extension end of the electric telescopic rod 6.

[0026] In summary, according to the structure shown in Figures 1 to 4, the operator first places the bearing to be quenched into the bearing support frame 71. Then, the controller opens the electric telescopic rod 6 on the top of the support plate 5. When the electric telescopic rod 6 starts running, the bearing support frame 71 moves towards the interior of the quenching tank 1 through the connection of the connecting plate 73 and the sliding of the T-shaped slide bar 72, thereby immersing the bearing in the quenching liquid for rapid cooling and quenching. When the bearing quenching time reaches the target, the controller opens the electric telescopic rod 6, causing the support assembly 7 to move the bearing out of the quenching liquid. Then, the controller turns on the drive motor 9 and the liquid pump 13. When the liquid pump 13 starts running... During operation, the filtered quenching fluid is delivered into the hollow fixed plate 123 through the infusion hose 125. When the drive motor 9 starts running, it drives the drive screw 10 to rotate inside the fixed bracket 8. At this time, through the connection of the connecting seat 121 and the guidance of the limiting guide rod 11, the connecting seat 121 moves laterally along the top of the quenching tank 1, thereby causing the fixed rod 122 to drive the hollow fixed plate 123 to move synchronously. Then, through the operation of the flushing nozzle 124, the quenching fluid in the hollow fixed plate 123 is automatically sprayed down for flushing. The impurities flushed down automatically flow back into the quenching tank 1 along with the quenching fluid and are automatically collected and processed by the impurity carrying box 3.
