[0001] The utility model relates to a material changing device for an automatic assembly mechanism of clutch parts and belongs to the technical field of automobile clutch assembly equipment. Background Art

[0002] The automobile clutch is a core component of the automobile, and the interior of the automobile clutch is mainly installed with clutch steel plates, friction plates, wave springs and pressure plates in a stacked manner, and the clutch steel plates, friction plates, wave springs and pressure plates are all in a ring shape. The existing installation of clutch steel plates, friction plates, wave springs and pressure plates is carried out by an automatic assembly mechanism for clutch parts. The automatic assembly mechanism for clutch parts includes a machine, a turntable assembly, a first grabbing assembly and a second grabbing assembly. The machine is equipped with a turntable assembly, and the machine on one side of the turntable assembly is provided with a first grabbing assembly. A second grabbing assembly is set on the machine platform on the other side of the disc assembly. When working, the staff first places the barrels containing the clutch steel plates, friction plates, wave springs and pressure plates stacked respectively on the material picking place of the machine platform, and then uses the first grabbing assembly to grab the clutch steel plates, friction plates, wave springs and pressure plates from their respective barrels in turn and place them on the turntable assembly. After the turntable assembly is rotated and transported, the second grabbing assembly grabs the stacked clutch steel plates, friction plates, wave springs and pressure plates in the turntable assembly as a whole and puts them into the clutch housing on the production line for assembly.

[0003] After the existing clutch automatic assembly mechanism grabs the clutch steel plate, friction plate, wave spring and pressure plate on the barrel, the barrel is often replaced manually. Since the barrel is stacked with multiple clutch steel plates, friction plates, wave springs and pressure plates, it has a large weight. Manual replacement of the barrel is cumbersome, time-consuming and labor-intensive, and the manual labor workload is large. The efficiency of barrel replacement is low, so it is necessary to improve it. Summary of the invention
