Description
Technical Field
[0001] This utility model relates to the field of metal heat treatment, and in particular to a heat treatment fixture for aluminum alloy wheel hubs. Background Technology
[0002] Aluminum alloy wheels are wheel components made of aluminum alloy. Heat treatment of aluminum alloy wheels is performed to improve their strength, hardness, toughness, and other properties. Heat treatment fixtures are tools used to fix and hold the wheel hub during the heat treatment process. Their function is to ensure the wheel hub maintains a stable position during heat treatment, prevent deformation, and guarantee the uniformity and consistency of the heat treatment effect.
[0003] The aluminum alloy wheel heat treatment fixture consists of a base, clamping device, positioning components, support components, and heat insulation components. The base serves as the foundation of the fixture, providing a stable mounting platform for other components and ensuring that the fixture does not shift or wobble due to heat or stress during heat treatment, thus guaranteeing the quality of the wheel heat treatment. The clamping device firmly fixes the aluminum alloy wheel to the fixture by applying uniform clamping force, preventing displacement, deformation, or wobble of the wheel due to thermal stress or other factors during heat treatment, ensuring that the wheel maintains a stable shape and position during heating and cooling. The positioning components ensure accurate installation of the aluminum alloy wheel in the fixture, ensuring proper contact between the wheel and the heat treatment plate. Maintaining a uniform distance and angle between the heating and cooling media in the heat treatment equipment ensures uniform heating and cooling of all parts of the wheel hub, thereby improving the consistency and quality stability of the heat treatment. The support components provide support at the bottom or side of the wheel hub, distributing the weight of the wheel hub and preventing deformation under its own weight. At the same time, they ensure the spatial position and posture of the wheel hub during the heat treatment process, which is conducive to the uniform transfer of heat and the uniform distribution of the cooling medium. The heat insulation components reduce the transfer of heat between the clamp and the wheel hub, reduce the influence of the clamp on the temperature field during the heat treatment of the wheel hub, prevent the clamp from being damaged due to overheating, and also help improve energy utilization efficiency, so that the heat is more concentrated on the wheel hub itself.
[0004] In existing technologies, some aluminum alloy wheel hub heat treatment fixtures are rigidly connected to the worktable of the heat treatment equipment via bolts, nuts, and other connectors to ensure that the fixtures will not loosen due to vibration, thermal stress, or other factors during operation. As a result, the fixtures are immobile. When it is necessary to quickly adjust the fixtures, change to different models of wheel hubs for heat treatment, or perform maintenance on the fixtures, the inability to move the fixtures will cause inconvenience to the operation, increase the difficulty and time cost of operation, and reduce the flexibility and efficiency of production. Therefore, an aluminum alloy wheel hub heat treatment fixture is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A heat treatment fixture for aluminum alloy wheel hubs includes a housing. A motor is fixedly connected to the bottom of the housing.

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the motor drives the rotating rod to rotate, thereby rotating the fixed shaft at the top of the rotating plate one, which in turn rotates the rotating plate two, causing the fixed plate to rotate as well, thus moving the moving plate one. This causes the moving plates one around the plate one to move closer to each other, thereby achieving the fixing of wheel hubs of different sizes. In addition, it improves the versatility and applicability of the fixture, which can meet various production needs; thus reducing enterprise costs, as there is no need to equip multiple fixtures for wheel hubs of different sizes.

[0031] 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.
[0032] Reference Figure 2 and Figure 3 This utility model provides an embodiment of an aluminum alloy wheel hub heat treatment fixture, including a housing 1. The housing 1 serves to protect the internal components, preventing dust, debris, etc. from entering and affecting the normal operation of each component. At the same time, it provides a stable mounting base for other components, ensuring the integrity and stability of the entire fixture structure. This allows each component to work collaboratively in a relatively fixed position, ensuring the smooth progress of the heat treatment process. A motor 2 is fixedly connected to the bottom of the housing 1. The motor 2 serves as the power source for the fixture, converting electrical energy into mechanical energy to drive the rotating rod 3 to rotate, thereby driving a series of subsequent mechanical structure movements. This enables the fixture to automate the operation of the aluminum alloy wheel hub. The drive end of the motor 2 is fixedly connected to the rotating rod 3. The rotating rod 3 receives the rotational power of the motor 2 and transmits it to the rotating plate 4. Through its own rotation, it drives the two rotating plates 4 to perform circular motion, realizing the initial distribution and transmission of force and motion. This provides the foundation for the complex movement of the entire fixture, ensuring that each component can move according to a predetermined trajectory and method, thereby achieving precise clamping and positioning of the wheel hub.
[0033] Two rotating plates 4 are fixedly connected to the outside of the rotating rod 3. The rotating plates 4 move in a circular motion driven by the rotating rod 3, and the centrifugal force generated is transmitted to the rotating plate 6 via the fixed shaft 5, thus transmitting and amplifying the force. The top of the rotating plate 4 is fixedly connected to the fixed shaft 5, which connects the rotating plates 4 and 6, allowing them to rotate relative to each other. This ensures effective force transmission and provides a support point for the swing of the rotating plate 6, ensuring the accuracy of the force transmission direction and motion trajectory. This allows the clamping mechanism of the fixture to work stably and reliably, guaranteeing the fixing effect of the hub during heat treatment. The rotating plate 6 is rotatably connected to the outside of the fixed shaft 5. The rotating plate 6 receives the force transmitted from the fixed shaft 5 and converts it into a linear force that pushes the fixed plate 7, driving the fixed plate 7 to move linearly through its own swing. A fixed plate 7 is fixedly connected to the other side of the rotating plate 6. The fixed plate 7 works in conjunction with the movable plate 8 to directly fix the aluminum alloy wheel hub. The top of the fixed plate 7 is rotatably connected to the movable plate 8. The movable block 9 on the top of the movable plate 8 is in direct contact with the aluminum alloy wheel hub. The fixed plate 7 drives the wheel hub to clamp. The top of the movable plate 8 is fixedly connected to the movable block 9. When clamping the wheel hub, the movable block 9 can protect the surface of the wheel hub from being scratched and increase the friction between the wheel hub and the wheel hub, further improving the stability of the clamping and preventing the wheel hub from sliding when affected by thermal stress, vibration and other factors. This ensures the positional accuracy and posture stability of the wheel hub during the heat treatment process, guarantees the uniformity and consistency of the heat treatment, and improves the quality and performance of the aluminum alloy wheel hub. A heat dissipation component for rapid heat dissipation is fixedly connected to the front side of the outer shell 1.
[0034] Reference Figure 2 and Figure 4 The heat dissipation component includes a filter plate 10, which prevents external dust and debris from entering the interior of the housing 1 through the vent. When the suction fan 11 is working, it filters the air. The rear side of the filter plate 10 is fixedly connected to the front side of the housing 1. Two suction fans 11 are fixedly connected to the inner wall of the rotating rod 3. After the heat treatment is completed, the suction fan 11 is driven to quickly dissipate heat. The outside of the rotating rod 3 has an oblique opening to guide the airflow.
[0035] Reference Figures 1 to 3The rotating rod 3 is externally rotatably connected to the inner wall of the outer casing 1. The motor drives the rotating rod 3 to rotate, thus causing the rotating rod 3 to rotate on the outer casing 1. The left and right sides of the moving block 9 are slidably connected to the top of the outer casing 1. The top of the outer casing 1 is provided with a sliding groove, and the moving block 9 moves within the sliding groove to clamp objects. A grooved plate 12 is fixedly connected to the top of the moving block 9. The grooved plate provides a rotation space for the rotating rod 3 to rotate. The top of the grooved plate 12 has a slot, and a rotating rod 14 is rotatably connected inside the grooved plate 12. Rotating rod 2 (14) rotates within the grooved plate, causing rotating plate 3 (13) to rotate, thus rotating its inclined shaft. Rotating plate 3 (13) is fixedly connected to the outside of rotating rod 2 (14). Rotating plate 3 (13) rotates inside the grooved plate, receiving the force from rotating rod 2 (14) and driving the inclined shaft to rotate. Rotating plate 4 (15) is fixedly connected to the front of rotating rod 2 (14), serving as an intermediate connecting component, thus enabling its rotation. Rotating rod 3 (16) is fixedly connected to the front of rotating plate 4 (15), moving within a guide plate. Under the action of the inclined groove of the guide plate... This allows for rotation. Two fixing blocks 17 are fixedly connected to the rear side of the rotating plate 13. These fixing blocks 17 receive the force from the rotating plate 13 and transmit it to the inclined shaft 18. The tops of both fixing blocks 17 are fixedly connected to the inclined shaft 18. The inclined shaft 18 rotates during movement, thus providing secondary fixation to the object, making it more stable. The outer surface of the inclined shaft 18 contacts the inside of the grooved plate 12 during the rotation of the rotating plate 13. After movement, the outer surface of the inclined shaft contacts the inside of the grooved plate. Multiple... A guide plate 19 guides the rotating rod 3 to slide within the sliding groove 3, thereby causing it to rotate. A sliding groove 2 is formed in the middle of the guide plates 19. A slot is formed at the top of the rotating rod 3, allowing the cold air drawn in by the suction fan to quickly contact the hot object. The bottom of the moving plate 8 contacts the rotating plate 4 under the rotation of the fixed plate 7. The moving plate 8 moves closer to the rotating plate 4, causing them to contact each other. Ventilation openings are formed around the perimeter of the outer casing 1, providing channels for air to enter and exit. Under the action of the suction fan 11, outside cold air can enter the interior of the outer casing 1 through the ventilation openings. The filter plate 10 has filter holes inside, effectively filtering the cold air. The ventilation openings and filter holes are interwoven, filtering out fine impurities and allowing the cold air to enter the interior.
[0036] Working principle: When heat treating wheel hubs of different sizes, firstly, motor 2 is started. The drive end of motor 2 rotates the rotating rod, causing the rotating plate 4 to rotate, which in turn rotates the multiple fixed shafts 5 on its top, causing the rotating plate 6 to rotate, which in turn rotates the fixed plate 7. The rotation of the fixed plate 7 then drives the moving plate 8 to rotate, causing the moving block 9 to move with the moving plate 8. The movement of the moving block 9 causes the rotating rod 14 to move inside the guide plate 19, causing the rotating plate 15 to rotate, which in turn rotates the rotating rod 16, causing the rotating plate 13 to rotate. This causes the inclined shaft 18 on the fixed block 17 to rotate as well. After the moving block 9 fixes the wheel hub, the inclined shaft 18 on the fixed block 17 is also fixed to the upper part of the wheel hub, thus achieving the fixation of wheel hubs of different sizes. In addition, it improves the versatility and applicability of the fixture, which can meet various production needs; thereby reducing enterprise costs and eliminating the need to equip multiple fixtures for wheel hubs of different sizes.
[0037] After the wheel hub has undergone heat treatment and is being cooled, motor 2 starts the suction fan 11. The suction fan 11 draws in the cold air inside the outer casing 1. The slanted openings around the rotating rod prevent the cold air from easily escaping. The cold air enters the rotating rod and, under the action of the suction fan 11, directly dissipates heat from the heat-treated wheel hub. Under the action of the suction fan 11, external cold air quickly enters the outer casing 1. Under the action of the filter plate 10, impurities in the external cold air are filtered out. The suction fan 11 also enables rapid heat dissipation for the clamp and wheel hub, ensuring stable heat treatment and improving product quality. This extends the service life of the clamp and wheel hub and reduces maintenance costs.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
