Description

Technical Field

[0001] The invention relates to the technical field of assembly clamping tooling, and in particular to a clamping device for assembling a children's toy car. Background Art

[0002] Children's toy cars are toys designed for children. They usually have bright colors, rich sounds and easy operation to attract children's attention. Toy cars are not only a recreational tool for children, but also can train children's spatial thinking, logical thinking, number sense, observation, color matching, hand-eye coordination and other abilities through a series of early education games, so that they can experience the fun of driving while also exercising their reaction speed and operation skills.

[0003] There are many types of toy cars, including cars, trains, trucks, excavators, remote control cars, etc. Each vehicle has its own unique characteristics and functions. In recent years, large electric cars that can be driven by children have gradually emerged. This kind of children's toy car can be regarded as a smaller version of an ordinary car. It also has a complete drive motor, chassis, body and driving control system. The difference is that since toy cars are only for children to drive and play, they are usually smaller in size and relatively simple in structure.

[0004] Similar to the manufacturing of ordinary cars, the production of children's toy cars also includes the stamping of chassis frames, welding of axle parts, spraying of door panels, and assembly of the whole vehicle. Specifically, for the assembly of children's toy cars, the specific process is to organically combine the processed frame, front and rear panels, side door panels and wheels through a variety of connection methods to make it a complete body. During the processing, in order to ensure the assembly accuracy, it is usually necessary to use specific clamping equipment to clamp and position different assembly parts. However, due to the complexity of the assembly process of children's toy cars, the existing clamping tooling often has many problems when used for the assembly clamping of toy cars:

[0005] 1. The clamping and positioning method is single, and it is difficult to achieve adaptive clamping of different assembly parts and different connection methods.

[0006] 2. There are many assembly parts, and different clamping mechanisms need to be set for different assembly parts. However, interference is prone to occur during the operation of different clamping mechanisms, making it difficult to carry out the assembly process continuously.

[0007] 3. During the assembly process, it is difficult to realize the automation of clamping in multiple processes such as loading, parts transfer and unloading, resulting in reduced overall assembly efficiency.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
