Description

Technical Field

[0001] This utility model belongs to the field of automotive steel wheel processing technology, specifically relating to a fixing structure for automotive steel wheel processing. Background Technology

[0002] Car rims, also known as car wheels or rims, are an important component of a car. They are responsible for bearing the weight of the car and transferring it to the tires. The manufacturing of car rims is a complex engineering process involving multiple procedures and precise technical requirements.

[0003] The prior art patent CN222002686U discloses a fixing structure for processing automotive steel rims. This structure involves placing the automotive steel rim into a rim groove, rotating a handle to rotate adjusting teeth, causing a sliding rod to slide to both sides. Limiting rings on both sides fix the inner position of the automotive steel rim, facilitating processing. However, during processing, the steel rim itself carries weight, and the device relies solely on the rotation of the adjusting teeth to drive the limiting rings for fixing. Due to its simplicity, the fixing effect is poor, and loosening easily occurs during grinding. Furthermore, the work efficiency is low. To address these issues, a new fixing structure for processing automotive steel rims is proposed. Utility Model Content

[0018] Please see Figure 1 - Figure 2 As shown, this utility model provides the following technical solution:

[0019] The system includes a workbench 1 mounted on a support frame. A support plate 2 is located below one side of the workbench 1, and the workbench 1 overlaps the support plate 2. The corresponding other side is hinged to the support frame. A lifting mechanism passing through the support plate 2 is provided on the support frame. The telescopic end of the lifting mechanism is hinged to the back of the workbench 1 overlapping the support plate 2. The lifting mechanism is a hydraulic cylinder. A hydraulic cylinder movement channel is provided at the overlap between the workbench 1 and the support plate 2. When loading and unloading steel rings, the hydraulic cylinder cooperates to lift and lower, reducing the physical exertion of workers and effectively improving work efficiency.

[0020] The middle part of the workbench 1 is set as a steel rim processing part. A fixing mechanism 3 for fixing automobile steel rims is provided on the processing part. The fixing mechanism 3 includes a fixing block 301 that cooperates with the outside of the steel rim and three push plates 302 that cooperate with the inside of the steel rim. The fixing block 301 and the push plates 302 are evenly distributed in the circumferential direction. The workbench 1 is provided with a driving mechanism 303 that drives the three push plates to extend and retract simultaneously.

[0021] The worktable 1 is provided with a movable groove 4 that cooperates with the drive mechanism 303. The length of the movable groove 4 matches the movement trajectory of the push plate 302. The drive mechanism 303 includes a first drive shaft 3031, and a second drive shaft 3032 is laterally connected to the center of the first drive shaft 3031. A set of meshing bevel gears 3033 is provided at the connection between the first drive shaft 3031 and the second drive shaft 3032. The set of meshing bevel gears 3033 consists of two bevel gears. One bevel gear is mounted on the first drive shaft 3031, and the other... A shaft end is fitted onto the top of the second drive shaft 3032 facing the first drive shaft 3031. Threads are provided on both sides of the first drive shaft 3031 and the second drive shaft 3032. The threads of the first drive shaft 3031 are arranged opposite to each other. Connecting plates 3034 are respectively provided at the threads of the first drive shaft 3031 and the second drive shaft 3032. The top of the connecting plate 3034 is connected to the bottom of the push plate. A motor 3035 is provided on one side of the first drive shaft 3031. The output end of the motor 3035 is connected to the first drive shaft 3031.

[0022] The first drive shaft 3031 and the second drive shaft 3032 are fixed to the bottom of the workbench 1 by the mounting base 5. The first drive shaft 3031 and the second drive shaft 3032 are slidably connected to the mounting base 5. The first drive shaft 3031 and the second drive shaft 3032 are located below the movable groove and their length is greater than the length of the movable groove. The connecting plate 3034 is provided with a screw hole, which matches the thread of the first drive shaft 3031 and the second drive shaft 3032. The height of the connecting plate 3034 is higher than the height of the movable groove.

[0023] During operation, the hydraulic cylinder lifts the worktable. After lifting, the steel ring is placed on the worktable and secured by a fixing block. Once placed, the worktable slowly descends to a horizontal position, and the drive mechanism is activated to secure the steel ring. First, the motor drives the first and second drive shafts to rotate. The threads on the first and second drive shafts move the connecting plate. When the push plate clamps the steel ring, the motor stops working. After the drive device finishes its work, the worker performs a series of processing steps on the secured steel ring. After processing, the drive device drives the push plate to retract, and the worktable is lifted, allowing the worker to unload the steel ring.
