Description

Technical Field

[0001] The present invention relates to the technical field of five-axis cradle turntables, and in particular to a direct-drive five-axis cradle turntable brake system. Background Art

[0002] A direct-drive five-axis cradle turntable is a highly complex mechanical system designed to achieve multi-degree-of-freedom motion control, including rotation and tilting around multiple axes. In many applications, the turntable must be quickly and precisely stopped and locked during operation to ensure the accurate positioning and safety of the workpiece or equipment. Traditional braking systems typically use friction brakes or electromagnetic brakes to achieve this stopping function. Friction brakes rely on the contact of friction materials to brake the turntable, while electromagnetic brakes use electromagnetic force to achieve braking. However, these traditional braking systems have limitations in high-speed and high-precision applications. Summary of the Invention

[0004] To achieve the above-mentioned objectives, the main technical solutions adopted by the present invention include: a direct-drive five-axis cradle turntable brake system, including a drive shaft, a brake pressure cover, a brake pad, a brake piston, a turntable bearing and a water jacket, the drive shaft is installed in the water jacket through the turntable bearing, the drive shaft is provided with a brake surface in the radial direction, the brake pad is installed on one side of the brake surface, the water jacket is provided with a pressure chamber connected to the external oil corresponding to the brake surface, the brake piston is provided in the pressure chamber, the brake pressure cover is installed on the end face of the water jacket and contacts with the brake pad and the brake piston respectively, and the brake pressure cover is pushed away from the brake pad by the brake piston.

[0005] The brake gland is made of spring steel.

[0006] The turntable bearing is connected to the transmission shaft through a bearing gland.

[0007] The brake pressure cover includes a main body and a pressure ring connected to the main body as a whole. The pressure ring contacts the brake piston and the brake pad respectively, and the brake piston pushes the pressure ring away from the brake pad.

[0008] The beneficial effects of this invention include the ability to quickly and reliably stop a turntable in high-speed, high-precision applications while reducing wear and energy consumption. The development of this braking system is expected to improve the performance of direct-drive five-axis cradle turntables, providing safer and more reliable solutions in a variety of engineering fields.
