Description

Technical Field

[0001] The invention relates to the technical field of clamping devices, and in particular to a clamping device for automobile parts. Background Art

[0002] The wheel hub is an important part of the car. It not only supports the tire, but also bears the load of the vehicle together with the tire. Parameters such as the wheel hub's size, width, PCD, offset and center hole will affect the use and performance of the vehicle. The wheel hub's size usually refers to the diameter, and the width is also called the J value. Both of these directly affect the choice of tires. PCD refers to the diameter between the central fixing bolts of the wheel hub, and the offset is the distance between the bolt fixing surface and the geometric center line of the wheel hub, which determines whether the wheel hub is retracted inward or bulged outward.

[0003] Before clamping, the wheel hub is inspected to ensure that it has no damage or defects. The wheel hub is manually placed in the correct position, and a suitable clamping device is selected according to the size and shape of the wheel hub. The wheel hub is manually fixed on the clamping device. In the automated production line, after the wheel hub is clamped, it is moved to the next workstation by a conveyor belt or a robotic arm, and the wheel hub is processed or assembled with other parts in the clamped state.

[0004] When the above-mentioned automobile parts clamping device is in use, since the wheel hub needs to be manually moved to the correct clamping position, a clamping device with the same size as the wheel hub needs to be selected for clamping. The use of an incompatible clamping device will lead to unstable clamping, thereby affecting production efficiency. The use of a clamping device with mismatched sizes may easily cause the wheel hub to fall off or move during processing, thereby increasing the risk of damage to the wheel hub, and the position of the manually placed wheel hub is prone to deviation. If the wheel hub position is inaccurate, necessary position correction is performed to ensure the accuracy of the wheel hub during processing or assembly, resulting in a slower handling speed, which will affect the efficiency of the entire production line. Summary of the invention

[0017] 1. A rotating wheel is connected to the fixed shaft on one side of the sliding column. When the sliding column slides down, it will slide along the sliding groove on the sliding sleeve, driving the clamping rotating plate on the top of the sliding column to drive the clamping wheel to rotate, and clamp the wheel hub on the placement plate. The weight of the wheel hub can provide additional stability, making the clamping more secure and reducing vibration and displacement during processing. Gravity clamping is suitable for a variety of wheel hubs of different weights and shapes, with good adaptability, which can reduce the time of loading and unloading the wheel hub, thereby improving overall production efficiency.

[0018] 2. When the sliding frame slides, the fixed plate on the upper surface will slide at the same time, so that the positioning wheel 1 and the positioning wheel 2 on the fixed column slide along the interval between the rollers, and the wheel hub on the roller is squeezed and calibrated for placement. The accurate loading position can reduce the subsequent adjustment time, speed up the production process, and improve the overall efficiency. The correct loading position can prevent the wheel hub from being subjected to unnecessary impact or scratches during the loading process, ensuring that the wheel hub is in the correct position during the clamping process or assembly process, which can improve the processing accuracy and reduce errors.
