Description

Technical Field

[0001] This utility model relates to the field of wheel hub heat treatment technology, and in particular to an automated heat treatment device for automobile wheel hubs. Background Technology

[0002] The wheel hub is the part at the center of the wheel where the axle is mounted, also known as the "wheel rim" or "steel rim". During the remanufacturing of automobile wheel hubs, heat treatment is required to improve their hardness and other properties, so automated heat treatment equipment is used.

[0003] A search revealed a Chinese patent for an automated heat treatment device for automotive wheel hubs (authorization announcement number CN211284473U). The device includes a main body with a top cover at its upper end and a sliding door on one side. A connecting block is located on the outer front surface of the main body, and explosion-proof glass is installed on the outer front surface of the connecting block. A control panel is located on the outer front surface of the explosion-proof glass. A heater is installed on the inner outer surface of the main body, surrounded by a heat insulation layer. A temperature sensor is located near the lower corner of the main body. A base plate is located at the lower end of the main body, and a turntable is located on the upper end of the base plate. A heat treatment column is located at the center of the upper outer surface of the turntable. This patented technology ensures uniform heating of the wheel hub, which is beneficial for subsequent processing, and also effectively protects the user, resulting in higher safety.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that the wheel hub needs to be placed on the heat treatment fixing bracket inside the device. However, during the heat treatment process, this method requires the wheel hub to be repeatedly taken out and put back in, which is inconvenient and cannot form a continuous heat treatment operation. In addition, the contact surface between the heat treatment fixing bracket and the wheel hub cannot be heated, which will reduce the heat treatment effect on the wheel hub. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main objective of this utility model is to provide an automated heat treatment device for automobile wheel hubs.

[0006] The technical solution of this utility model is as follows: an automated heat treatment device for automobile wheel hubs includes a treatment box. Two transmission components are provided on the top of the inner wall of the treatment box. Slide grooves are provided on all four sides of the inside of each transmission component. A screw is rotatably connected inside the slide groove. A threaded block is threadedly connected to the outside of the screw. A connecting rod is rotatably connected to all four sides of the threaded block. A rotating plate is rotatably connected to all four sides of the bottom of the transmission component. The rotating plate is rotatably connected to the corresponding connecting rod.

[0007] In a preferred embodiment, the processing box is provided with a conveying assembly, which includes a conveyor frame fixedly connected to the inner wall of the processing box. Both ends of the conveyor frame are rotatably mounted with drive rollers, and a conveyor belt is connected between the two drive rollers.

[0008] In a preferred embodiment, a fixing rod is fixedly connected inside the groove and around the screw, and the fixing rod is slidably connected to the threaded block.

[0009] In a preferred embodiment, the processing box has an air inlet inside, a fixed frame is fixedly connected inside the air inlet, a fan is installed on one side of the fixed frame, and a controller is fixedly installed on the outside of the processing box.

[0010] In a preferred embodiment, a drive motor b is fixedly mounted on the top of the transmission component, and the output shaft of the drive motor b extends into the interior of the transmission component and is fixedly connected to the screw.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the rotation of the screw drives the threaded block to move up and down, thereby enabling the connecting rod to push the corresponding rotating plates to unfold one by one. In turn, multiple rotating plates can be used to clamp and fix the inner wall of the hub. Subsequently, the hub is separated from the conveyor belt by the cylinder, thereby enabling the heat treatment operation on the outer surface of the hub, which significantly increases the heat treatment effect.

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1-4 An automated heat treatment device for automobile wheel hubs includes a treatment box 1. Two transmission components 9 are installed on the top of the inner wall of the treatment box 1. Each transmission component 9 has a sliding groove 10 around its perimeter. A screw 13 is rotatably connected inside the sliding groove 10. A threaded block 12 is threadedly connected to the outer side of the screw 13. A connecting rod 16 is rotatably connected around the perimeter of the threaded block 12. Rotating plates 14 are rotatably connected around the bottom perimeter of the transmission components 9. The rotating plates 14 are rotatably connected to the corresponding connecting rods 16. During the heat treatment operation of the wheel hub, the operator can control the start of the drive motor b15 to drive the screw 13 to rotate, thereby causing the threaded block 12 to move up and down. This allows the connecting rods 16 to push the corresponding rotating plates 14 to unfold one by one. Multiple rotating plates 14 can then be used to clamp and fix the inner wall of the wheel hub. Subsequently, a cylinder 7 separates the wheel hub from the conveyor belt 5, thus enabling heat treatment of the outer surface of the wheel hub, significantly increasing the heat treatment effect.

[0023] Specifically, the processing box 1 is equipped with a conveying assembly, which includes a conveyor frame 2 fixedly connected to the inner wall of the processing box 1. Both ends of the conveyor frame 2 are rotatably mounted with drive rollers, and a conveyor belt 5 is connected between the two drive rollers. The rotation of the drive rollers can drive the drive motor b15 to operate, thereby driving multiple car wheel hubs for conveying purposes without the need for manual removal or placement in the middle, reducing the heat treatment time of the wheel hubs and improving work efficiency. The inside of the slide 10 and around the screw 13 are fixedly connected with fixing rods 11, and the fixing rods 11 are slidably connected to the threaded blocks 12. The processing box 1 has an air inlet, and a fixing frame is fixedly connected inside the air inlet. A fan 17 is installed on one side of the fixing frame. The fan 17 can increase the air flow speed inside the processing box 1, further improving the heat treatment efficiency. A controller 6 is fixedly installed on the outside of the processing box 1.

[0024] Specifically, a drive motor b15 is fixedly installed on the top of the transmission component 9. The output shaft of the drive motor b15 extends into the interior of the transmission component 9 and is fixedly connected to the screw 13. The rotation of the output shaft of the drive motor b15 can drive the screw 13 to rotate, thereby realizing the transmission of power. A heater 8 is fixedly installed on the top of the processing box 1. Hanging curtains 4 are fixedly connected at equal intervals on both sides of the processing box 1. Cylinders 7 are fixedly installed on the top of the processing box 1 and on both sides of the heater 8. The height of the hub and the transmission component 9 can be adjusted by using the cylinders 7. A drive motor a3 is fixedly installed on the outside of the conveyor frame 2. The output shaft of the drive motor a3 is fixedly connected to one of the transmission rollers. The piston rods of the cylinders 7 are fixedly connected to the corresponding drive motors b15.

[0025] Working principle: First, the operator can start the drive motor a3 and heater 8 through the controller 6, which drives the transmission roller to rotate, thereby driving the drive motor b15 to operate. This allows multiple car wheel hubs to be transported without manual removal or placement. Then, the drive motor b15 can be started. The rotation of the output shaft of the drive motor b15 drives the screw 13 to rotate, thereby driving the threaded block 12 to move up and down. This allows the connecting rod 16 to push the corresponding rotating plates 14 to unfold one by one. This allows multiple rotating plates 14 to clamp and fix the inner wall of the wheel hub. Then, the cylinder 7 separates the wheel hub from the conveyor belt 5, thereby performing heat treatment on the outer surface of the wheel hub, significantly increasing the heat treatment effect. The fan 17 increases the air flow speed in the treatment box 1, further improving the heat treatment efficiency.
