Description

Technical Field

[0001] This utility model relates to the field of bearing heat treatment technology, specifically a heat treatment device for wheel hub bearings. Background Technology

[0002] Wheel bearings are one of the key components of automobiles. Their main function is to bear weight and provide precise guidance for the rotation of the wheel hub. During the manufacturing process of wheel bearings, the components on them need to be heat-treated. Due to the small size of the components of wheel bearings, the heat treatment uniformity is low and the treatment effect is poor.

[0003] A search revealed that patent application CN211142105U discloses a heat treatment device for wheel hub bearings, comprising a treatment chamber, a placement shaft, a heating device, a heating nozzle, a water pump, and a cover plate. The placement shaft is located in the middle of the treatment chamber, the heating device is located at the bottom of the treatment chamber, and the heating nozzle is located at the top of the heating device, below the placement shaft. Water pumps are located on both sides of the treatment chamber, and a cover plate is located on the top of the treatment chamber. A water outlet pipe is located inside the cover plate. This design can stably fix the bearing in place and prevent damage to the bearing during the heat treatment process.

[0004] However, due to the installation clamp, which holds and fixes the small bearing in place, the area of ​​the bearing that is blocked is too large, resulting in uneven heat treatment and poor heat treatment effect. At the same time, since the bearing is cooled by the water outlet pipe, the water sprayed out cannot be recycled, resulting in high water resource costs and low environmental protection.

[0005] Therefore, we propose a heat treatment device for wheel hub bearings. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a heat treatment device for wheel hub bearings, which solves the problems of poor heat treatment effect and high operating cost of existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a heat treatment device for wheel hub bearings, including a treatment box, four sets of support legs are fixedly installed on the bottom surface of the treatment box, and a box door of appropriate specifications is assembled on the front side of the treatment box.

[0008] The top surface of the processing box is equipped with a stepper motor, and the top of the processing box is equipped with a rotating shaft that is fitted onto the output end of the stepper motor. A placement column is fixedly installed on the bottom surface of the rotating shaft. The outer wall of the placement column is equipped with evenly distributed hooks. The outer wall of the hooks is provided with a limiting groove that matches the bearing specifications. The hooks are connected to the placement column through a slot.

[0009] A water tank of the same specifications is fixedly installed at the bottom of the treatment box. Two sets of fixed plates that are opposite to each other and inclined are fixedly installed on the top surface of the water tank. A drainage gap is left between the fixed plates. A pressure seat is fixedly installed on the rear side of the treatment box. A water pipe is connected between the water tank and the pressure seat. A water pump is installed on the outer wall of the water pipe. A spray plate connected to the pressure seat is fixedly installed on the inner wall of the rear side of the treatment box. The spray plate is opposite to the placement column. The front side of the spray plate has evenly distributed spray holes.

[0010] Preferably, heating boxes are fixedly installed on the left and right sides of the processing box, and electric heating plates connected to the heating boxes are fixedly installed on the inner walls of the left and right sides of the processing box. This allows for heat treatment of the bearings and improves the uniformity of the heat treatment.

[0011] Preferably, a protective plate of the same specifications is fixedly installed on the inner side of the heating plate, and the inner side of the protective plate is provided with evenly distributed heating holes, so as to prevent water sprayed by the spray plate from entering the heating plate.

[0012] Preferably, a temperature sensor is fixedly installed on the top of the processing chamber, and a control panel is installed on the front side of the chamber door, with a temperature display screen installed on the front side of the control panel. This allows the temperature inside the processing chamber to be adjusted as needed, thereby improving the heat treatment effect.

[0013] Preferably, a cylinder is fixedly installed on the bottom surface of the treatment box, and a push rod fitted on the output end of the cylinder is mounted on the bottom of the treatment box. A sealing plate of the same specification is fixedly installed on the top of the push rod.

[0014] Preferably, a sealing gasket is fitted on the top surface of the sealing plate, which can improve the sealing effect of the sealing plate.

[0015] 1. The heat treatment device for wheel hub bearings, through the setting of a stepper motor, a hook and a limiting groove, hangs the bearing on the hook and places it in the limiting groove. The limiting groove limits the bearing. The stepper motor drives the placement column to rotate slowly to ensure the stability of the bearing, increase the contact area between the bearing and the air, thereby improving the uniformity of heat treatment and the heat treatment effect.

[0016] 2. Simultaneously, through the setting of water tank, water pipe and spray plate, the spray plate sprays water to cool the bearing through the spray hole. The water automatically flows into the water tank, and then circulates into the pressurization seat under the action of water pump and water pipe.
