Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy wheel hub manufacturing technology, and in particular to a general-purpose aluminum alloy wheel hub lifting tool. Background Technology

[0002] During the manufacturing process of aluminum alloy wheels, the wheels need to be continuously transferred through various stages of the production line to complete all processing operations. For example, after the aluminum alloy wheels have undergone heat treatment, they are transported to the off-line area via roller conveyors, where different models of wheels need to be sorted and placed onto their respective pallets. Currently, this process relies on manual handling, requiring workers to manually move the heat-treated wheels onto the pallets. However, each wheel weighs approximately 35 kilograms, making manual handling extremely labor-intensive and inefficient. Furthermore, the heat-treated wheels often retain a high residual temperature, posing a risk of burns during manual handling.

[0003] Therefore, developing a universal aluminum alloy wheel hub lifting tool for practical production is an urgent problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a universal aluminum alloy wheel hub lifting tool to address the above-mentioned problems, thereby solving the issues of high labor intensity, low transfer efficiency, and risk of burns during the existing wheel hub manufacturing process when manually handling wheel hubs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A general-purpose aluminum alloy wheel hub lifting device includes a frame, with claw assemblies movably connected to both sides of the frame. The claw assemblies are generally hook-shaped and include a movable swing arm that is hinged to the frame. The tail end of the movable swing arm is connected to a claw for securing the wheel hub. The top of the frame is provided with a lifting lug for connecting to lifting machinery.

[0007] Preferably, the frame is provided with a pneumatic mechanism for driving the claw assembly. The pneumatic mechanism includes a telescopic cylinder fixedly connected to the frame. The telescopic end of the telescopic cylinder is hinged to a connecting rod, and the tail end of the connecting rod is hinged to the claw assembly. The telescopic cylinder drives the connecting rod to reciprocate through its telescopic movement, and drives the movable swing arm to produce a flipping action.

[0008] Preferably, the upper extension end of the movable swing arm is provided with a hinge shaft, and the tail end of the connecting rod is connected to the hinge shaft.

[0009] Preferably, the pawl is a V-shaped structure with two locking points to ensure the stability of the wheel hub locking.

[0010] Preferably, the chuck is provided with a flexible pad to prevent the chuck from directly contacting the wheel hub.

[0011] Preferably, the frame is provided with weight-reducing holes to reduce the structural weight.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention eliminates the need for manual handling of wheel hubs, effectively improving the problems of high labor intensity and low transfer efficiency associated with manual wheel hub handling. Furthermore, it eliminates the risk of burns from the high temperature of the wheel hubs as workers do not need to directly contact them during operation. Simultaneously, the claw assembly of the articulated frame can meet the clamping and lifting needs of wheel hubs of different sizes through the swing angle of the movable arm, enhancing the applicability and versatility of this invention. The pneumatic mechanism, through the extension and retraction of the telescopic cylinder, drives the connecting rod to reciprocate, causing the movable arm to rotate, thus creating the action of the claws clamping or releasing the wheel hub, enhancing the firmness of the claw assembly in securing the wheel hub.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1-3As shown, a general-purpose aluminum alloy wheel hub lifting tool includes a frame 10. Claw assemblies 20 are movably connected to both sides of the frame 10. The claw assemblies 20 are generally hook-shaped and include movable swing arms 21 hinged to the frame 10. The tail end of each movable swing arm 21 is connected to a claw 22 for securing the wheel hub. A lifting lug 11 is provided at the top of the frame 10 for connecting to lifting machinery such as an electric hoist. In use, this utility model connects to the lifting machinery via the lifting lug 11. The operator controls the lifting machinery to move the lifting tool to the wheel hub lifting position, flips the claw assembly 20 outwards, causing the two movable swing arms 21 to open and secure the claw 22 to the concave portion under the wheel lip of the wheel hub. The lifting machinery then lifts and transfers the wheel hub to the designated area.

[0021] This embodiment uses a lifting device to lift and transfer wheel hubs, eliminating the need for manual handling. This effectively improves the problems of high labor intensity and low transfer efficiency associated with manual wheel hub handling. Furthermore, workers do not need to directly contact the wheel hubs during the operation, reducing the risk of burns from the high temperatures. Simultaneously, the claw assembly 20 of the hinged frame 10 can meet the clamping and lifting needs of wheel hubs of different sizes through the swing angle of the movable swing arm 21, enhancing the applicability of this invention.

[0022] In a preferred embodiment, the frame 10 is equipped with a pneumatic mechanism 30 for driving the claw assembly 20. The pneumatic mechanism 30 includes a telescopic cylinder 31 fixedly connected to the frame 10. The telescopic end of the telescopic cylinder 31 is hinged to a connecting rod 32, and the tail end of the connecting rod 32 is hinged to the claw assembly 20. The telescopic movement of the telescopic cylinder 31 drives the connecting rod 32 to reciprocate, causing the movable swing arm 21 to rotate, thus enabling the claw 22 to clamp or release the wheel hub. Specifically, the upper extension end of the movable swing arm 21 is provided with a hinge shaft 23, and the tail end of the connecting rod 32 is connected to the hinge shaft 23. This embodiment enhances the firmness of the claw assembly 20 in securing the wheel hub through the configuration of the pneumatic mechanism 30.

[0023] Preferably, such as Figure 3 As shown, the chuck 22 has a V-shaped structure with two locking points to ensure the stability of the wheel hub. In use, the two locking points of the V-shaped structure of the chuck 22 are secured to the wheel hub, preventing the wheel hub from tipping over or slipping during transport, thus ensuring a stable and reliable transport process.

[0024] Preferably, the claw 22 is provided with a flexible pad 24 to prevent the claw 22 from directly contacting the wheel hub, effectively preventing scratches on the wheel hub. Furthermore, the flexible pad 24 increases the coefficient of friction between the claw 22 and the wheel hub, preventing the wheel hub from slipping or falling off, further ensuring the stable and reliable securing of the wheel hub. Preferably, the flexible pad 24 can be made of flexible materials such as rubber or polyurethane.

[0025] Preferably, such as Figure 1-2 As shown, the frame 10 has weight reduction holes 12 to reduce the structural counterweight, providing a lightweight wheel hub lifting device while meeting structural strength requirements.

[0026] The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
