Description

Technical Field

[0001] The invention belongs to the technical field of friction plate manufacturing, and in particular relates to an automatic plate loading machine for manufacturing friction plates. Background Art

[0002] Friction plate refers to a component composed of a chip and a friction lining or a friction material layer. It is widely used in the fields of mechanical engineering, mechanical parts and clutches. The braking part of the friction plate is the friction material. Friction material is a component material used in power machinery and relies on friction to perform braking and transmission functions. It mainly includes brake linings and clutch facings. Brake pads are used for braking, and clutch plates are used for transmission. Any mechanical equipment and various moving vehicles must have braking or transmission devices. Friction materials are key components in such braking or transmission devices. Its most important function is to absorb or transmit power through friction, such as clutch plates transmitting power and brake pads absorbing kinetic energy. They enable mechanical equipment and various motor vehicles to work safely and reliably. The basic structure of the friction plate is the friction material and the disc to which it is attached and fixed. When manufacturing the friction plate, the friction material and disc that make up the friction plate need to be fixed together.

[0003] When manufacturing friction plates, they are usually assembled using a loading machine. The loading machine is usually a stamping and hot riveting structure, which fixes the disc and the friction material together by riveting. However, this solution relies more on manual operation. The specific operation is that the worker sets the rods that constitute the rivets inside the through holes reserved in the disc and the friction material, and then heats the rods on the friction plate facing the working part of the stamping and hot riveting machine. Finally, the rods on the friction plate are facing the stamping part of the stamping and hot riveting machine to complete the stamping of the two ends of the rods to form rivets, thereby completing the assembly of the friction plate. During the assembly process of the friction plate, the worker needs to do three things. The first is to place the rods in the through holes in the disc and the friction material. The second is to align the rods on the friction plate with the heating part of the stamping and hot riveting machine. The third is to align the heated rods on the friction plate with the stamping part of the stamping and hot riveting machine. These three steps consume more workers' energy. Summary of the invention

[0018] The rods arranged inside the disc hole and the body hole are prefabricated above the top pressure head on the lower side. The eddy current heater is sleeved inside the rod above the top pressure head by means of the telescopic method of the hydraulic rod on the lower side in cooperation with the rotating motor and the electric telescopic rod. Compared with the conventional hot riveting scheme, this heating method can heat the rod more thoroughly. The main body of the rod is a hollow rivet. Compared with the conventional heating scheme, the hollow rivet and the nail cone head can be completely filled in the internal space of the disc hole and the body hole, thereby achieving a better riveting effect to complete the fixation of the friction plate and the friction plate body;

The cooperation scheme of the pulley and the rotating table is a deceleration structure. The rotating table is supported by a table support. The transition part between the rotating table and the table support is a plane bearing and an outer cylindrical bearing. The structure in which the clearance spring presses the outer cylindrical bearing on the lower side eliminates the axial clearance between the rotating table and the table support. The plane bearing and the outer cylindrical bearing allow the rotating table to have good radial and axial bearing capacity and low rolling resistance, thereby improving the overall structural reliability.
