Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy wheel technology, specifically a cooling device for casting aluminum alloy wheels. Background Technology

[0002] Aluminum alloy wheels are increasingly favored by private car owners for their aesthetic appeal, safety, and comfort. Due to their lightweight and high manufacturing precision, aluminum alloy wheels exhibit minimal deformation and low inertial resistance during high-speed rotation. They possess the metallic properties of absorbing vibration and rebound forces, and are CNC machined for high dimensional accuracy, roundness, minimal runout, and good balance, resulting in a smooth and comfortable driving experience.

[0003] For cooling aluminum alloy wheels after casting, the wheels can be placed in coolant. However, due to the weight of the wheels, hydraulic drive is required to move them. Generally, the wheels can be stacked and transferred to the cooling box. However, the cooling and loading of the wheels requires a lot of manpower. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a cooling device for aluminum alloy wheel casting, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution:

[0006] Includes: a support side plate, a support base plate mounted on one side of the support side plate, a cooling box mounted on the top of the support base plate, and a screw motor mounted in a slot in the support base plate.

[0007] Also includes:

[0008] The support bottom ring is installed above the support base plate;

[0009] The fixed connecting plate is fixed to the top of the supporting bottom ring. The upper part of the supporting bottom ring is provided with an arc-shaped groove, and the movable connecting plate is slidably connected in the arc-shaped groove.

[0010] The surface of the fixed connecting plate and the connecting plate through holes is provided with several sets of connecting plate through holes distributed longitudinally;

[0011] A support plate is sleeved on the outside of the movable connecting plate, and a limiting insert is slidably inserted through the surface of the support plate.

[0012] The pressure strip is installed on the inner side of the supporting pressure plate, and a ball bearing is movably installed on the top of the pressure strip.

[0013] Furthermore, a hydraulic push rod is fixed to the side wall of the supporting side plate, and the output end of the hydraulic push rod is connected to a push rod connecting plate.

[0014] Furthermore, a support top ring is fixed to the top of the fixed connecting plate, and the support top ring is connected to the push rod connecting plate by a support rod.

[0015] Furthermore, the fixed connecting plate and the two sets of movable connecting plates are arranged in a triangular pattern, and the diameter of the limiting insert is matched with the diameter of the through hole in the connecting plate.

[0016] Furthermore, a limit spring is installed between the outer wall of the limiting insert and the support plate, and between the support plate and the support pressure plate.

[0017] Furthermore, the top of the supporting pressure plate is provided with a pressure plate groove, and both ends of the pressure plate strip are fixed with downward extending baffles, and the width of the pressure plate strip is adapted to the groove of the pressure plate groove.

[0018] Furthermore, a groove is provided at the bottom of the support top ring, and the tops of the two sets of movable connecting plates are slidably connected to the groove at the bottom of the support top ring.

[0019] Furthermore, the bottom end of the fixed connecting plate extends toward the center of the supporting bottom ring and is connected to a rotating connecting platform, and the bottom end of the movable connecting plate slides along the surface of the rotating connecting platform.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This application uses a fixed connecting plate and two sets of movable connecting plates arranged in a triangle, which allows multiple sets of wheel hubs to be cooled to be placed in the inner area of ​​the triangle. At the same time, the distance between one end of the two sets of movable connecting plates can be adjusted in an arc shape, thereby expanding the space between the two sets of movable connecting plates. This greatly reduces the difficulty of loading the wheel hubs in the early stage. After loading is completed, the gap between the two sets of movable connecting plates is reduced, thereby improving the stability of the wheel hubs during the transfer and cooling process.

[0022] This application features multiple sets of connecting plate through holes longitudinally formed on the surfaces of the fixed and movable connecting plates. Each set of connecting plate through holes can accommodate a limiting insert. After the supporting pressure plate is fitted over the movable connecting plate, the limiting insert can be inserted into the connecting plate through hole to limit the supporting pressure plate. This allows for adjustment of the distance between the upper and lower sets of supporting pressure plates according to the different thicknesses of the wheel hubs, leaving a certain gap between the upper and lower sets of wheel hubs, thereby improving the cooling effect. Furthermore, the use of freely rotatable ball bearings as support for the wheel hubs allows the ball bearings to slide during loading and unloading, further reducing the difficulty of loading and unloading.

[0027] 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.

[0028] Please see Figure 1-3 The system includes: a support side plate 1, a support base plate 5 installed on one side of the support side plate 1, a cooling box 7 installed on the top of the support base plate 5, and a screw motor 6 installed in the slot of the support base plate 5. The output end of the screw motor 6 is connected to a screw, and the screw is placed in the cavity of the support base plate 5. A movable sleeve is fitted around the screw and connected to the bottom of the cooling box 7. Driven by the screw motor 6, the cooling box 7 can slide along the upper part of the support base plate 5, thereby moving the cooling box 7 to below the support bottom ring 8. Then, the support bottom ring 8 carrying the aluminum alloy wheel hub falls into the slot of the cooling box 7, thus cooling the aluminum alloy wheel hub.

[0029] A hydraulic push rod 2 is fixed on the end face of the support side plate 1 near the support base plate 5, and the output end of the hydraulic push rod 2 is connected to the push rod connecting plate 3. The push rod connecting plate 3 can slide on the surface of the support side plate 1, while the other end of the push rod connecting plate 3 extends to one side and is connected to the support top ring 4 through a column. The support top ring 4 and the support bottom ring 8 adopt the same annular structure and are distributed opposite each other. The support top ring 4 and the support bottom ring 8 are connected by a fixed connecting plate 9 and two sets of movable connecting plates 12. The upper and lower ends of the fixed connecting plate 9 are fixed to the support bottom ring 8 and the support top ring 4, respectively. Arc-shaped sliding grooves are opened on the surfaces of the support bottom ring 8 and the support top ring 4, and the movable connecting plates 12 are connected by arc-shaped sliding grooves. The two ends of the connecting plate 12 can slide in the arc-shaped grooves of the supporting bottom ring 8 and the supporting top ring 4, respectively, thereby adjusting the distance between the two sets of movable connecting plates 12. The fixed connecting plate 9 and the two sets of movable connecting plates 12 form a triangle. Since the two sets of movable connecting plates 12 can slide, before loading, the two sets of movable connecting plates 12 can be slid to both sides to increase the distance between the two sets of movable connecting plates 12. After increasing the space, the wheel hub can be placed in the triangular space formed by the fixed connecting plate 9 and the movable connecting plate 12. Conversely, after loading, the two sets of movable connecting plates 12 can be moved to a closer position to improve the stability during the transfer and cooling of the wheel hub.

[0030] The bottom of the fixed connecting plate 9 extends toward the center of the supporting bottom ring 8 and is connected to the rotating connecting platform 10. At the same time, the bottom of the movable connecting plate 12 also extends toward the center of the supporting bottom ring 8 and slides in the groove of the rotating connecting platform 10. The bottom of the fixed connecting plate 9 and the bottom of the movable connecting plate 12 are used to support the bottommost wheel hub.

[0031] The fixed connecting plate 9 and the connecting plate through holes 13 have several sets of longitudinally distributed connecting plate through holes 13 on their surfaces; the supporting pressure plate 14 is sleeved on the outside of the movable connecting plate 12, and the inner groove space of the supporting pressure plate 14 is larger than the outer diameter of the movable connecting plate 12 and the fixed connecting plate 9. Therefore, the supporting pressure plate 14 can be longitudinally height adjusted outside the fixed connecting plate 9 and the movable connecting plate 12. A sliding groove is opened on the surface of the supporting pressure plate 14, and a limiting insert 15 is slidably connected in the sliding groove. The limiting insert 15 can move in the groove of the connecting plate through hole 13, and the limiting... After the insert 15 passes through the groove of the support plate 14 and the through hole 13 of the connecting plate, the position of the support plate 14 can be restricted. The outer wall of the limiting insert 15 is connected to the support plate, and a limiting spring 16 is installed between the support plate and the support plate 14. By pulling the limiting insert 15 outward, the limiting insert 15 is disengaged from the through hole 13 of the connecting plate, and the height of the support plate 14 can be adjusted. Conversely, through the elastic action of the limiting spring 16, the limiting insert 15 can be inserted into the groove of the through hole 13 of the connecting plate, thereby locking the height of the support plate 14.

[0032] The top of the support plate 14 is provided with a plate slot 17, and a plate strip 18 is inserted into the slot of the plate slot 17. Both ends of the plate strip 18 are fixed with downward extending baffles, and the width of the plate strip 18 is adapted to the slot of the plate slot 17. After the position of the support plate 14 is adjusted, the plate strip 18 is longitudinally locked in the plate slot 17. A ball bearing part 19 is movably installed on the top of the plate strip 18. The ball bearing part 19 is nested in the hole at the top of the plate strip 18, so that the ball bearing part 19 can rotate freely and cannot be displaced. During loading, the free rotation of the ball bearing part 19 can reduce the friction of the hub, thereby reducing the difficulty of loading and unloading.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
