Clever use of the open sleeve

When we grind the φ20mm outer circle shown in Figure 1, it is difficult to clamp. Because it is directly clamped on the outer circle of φ5mm, due to insufficient rigidity, vibration and deformation occur during grinding. In order to enhance the rigidity of the clamping part, an opening sleeve (Fig. 2) is added to the outer circle of φ5 mm, and the right end surface of the sleeve abuts against the A end surface of the part (Fig. 3). The problem of rigidity of the clamping portion is solved. It turns out that this method is simple and practical.

Ball Cock

A ballcock (also balltap or float valve) is a mechanism or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by José Antonio de Alzate y Ramírez, a Mexican priest and scientist, who described the device in 1790 in the Gaceta de Literatura Méxicana.[1] It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped, hence the name ballcock. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.
