In fact, the drum brake works by using the brake transmission mechanism to cause the brake shoe to press the brake lining against the inside of the brake drum, thereby generating braking force, and decelerating the wheel or stopping Brake drum within a short distance as needed to ensure Driving safety and ensuring that the car is parked reliably cannot be automatically slipped.

In fact, after the working surface of the brake drum is assembled with the hub, it needs to be finished by bearing hole positioning. The requirements for roundness and coaxiality tolerance of the working face of the mini-car are ≤0.03mm, the radial runout is ≤0.05mm, and the static unbalance is ≤1.5N/cm. Therefore, if you want to achieve the above performance indicators, you need to achieve through the brake drum balancer.

If the brake drum detects an unbalance in the rotating state, it is necessary to remove the quality that affects its balance according to the standard, which is what we call deduplication. Subsequent re-balancing detection is required to achieve the specified brake drum accuracy level.

The brake detection station consists of a rotary indexing table and a clamp mounted on it. Each brake assembly has a corresponding fixture. After manually installing the brake assembly on the fixture, the pneumatic clamp prevents the assembly from moving. A centralized mechanism ensures that the brake shoes are concentrated before the imaging process begins.

The vendor used an IEEE 1394 high resolution camera and the corresponding PCI card. A software-controlled power zoom lens provides full resolution of cameras accessing different brake models. A polarizer is provided to reduce the glare effect of the highly reflective component and to select a high frequency light source capable of controlling the intensity by software.
