Background
The steel backing is mainly used for fixing the friction material, so that the steel backing is convenient to install on a brake system. The disc brake is widely applied in the market at present, and almost all high-strength friction materials on disc brake pads are sintered on a steel plate and freely move in calipers under the pushing of a brake oil cylinder body. This steel plate is behind the friction plate and is therefore referred to as the steel backing. The steel backing is generally provided with rivets and mounting holes. After the steel backing is stamped and manufactured on a machine tool, an ultrasonic cleaning machine is needed to clean residual machine oil or lubricating oil and other dirt on the surface.
The ultrasonic cleaning is to utilize the cavitation, acceleration and direct current action of ultrasonic waves in liquid to directly and indirectly act on liquid and dirt, so that a dirt layer is dispersed, emulsified and stripped to achieve the purpose of cleaning. In the existing ultrasonic cleaning machine technology, for example, the suspension chain type ultrasonic cleaning machine provided by granted patent CN210546740U, a workpiece to be cleaned is suspended on a suspension rail, and then the cleaning workpiece is transferred from right to left to the inside of the device body through the control of a tensioning device, so that the floating oil on the liquid surface can be driven to the overflow port, and the probability of secondary pollution of the cleaning workpiece is reduced. For example, in a suspension type ultrasonic cleaning machine provided in patent CN210523260U, a connecting chain is installed at the lower end of the interior of the suspension chain, a basket is fixed at the lower end of the connecting chain, and a hot air drying groove is provided for drying the workpiece.
