[0002] The pin part is made of Greek Asco loy. When the part is in bar stock condition, it is heat treated according to HS461 to achieve a hardness of HRC42-HRC50 and an outer surface roughness of Ra0.4. After semi-finishing by turning, the outer diameter is ground with a centerless grinder to achieve the surface roughness Ra0.4 required by the drawing. The centerless grinder processing time is 15 seconds per piece. On-site operators need to manually feed the part to the machine at all times. The disadvantages of this method are: large batch size, long manual feeding time, low production efficiency, and difficulty in meeting the requirements of mass production of parts.

The upper and lower electromagnetic modules are spaced apart and positioned opposite each other. The upper vibrating seat is connected to the lower vibrating seat through the leaf spring. The feeding hopper is located on the upper vibrating seat and has a structure with a spiral track on the inner side.

[0006] Furthermore, the feeding hopper is a conical cylinder with an opening area larger than its bottom area, and the spiral track on the inner wall of the feeding hopper spirals from the bottom to the top of the opening of the feeding hopper.

[0010] Furthermore, it also includes a bracket and a mounting base, with the lower vibration seat fixed to the bracket via the mounting base.

[0011] Technical effects of this utility model:

[0012] Using the above technical solution, a pulse electromagnet is located under the hopper, which can make the hopper vibrate vertically. The inclined leaf spring drives the hopper to oscillate around its vertical axis. Due to this vibration, the parts inside the hopper rise along the spiral track. During the rise, the parts are screened or change their posture through a series of tracks. The parts can automatically enter the assembly or processing position in a uniform state according to the assembly or processing requirements. Its working purpose is to automatically and orderly arrange disordered workpieces and accurately transport them to the equipment through vibration. It can realize automatic feeding of parts, greatly improve work efficiency, and reduce operators, saving manpower and labor. Attached Figure Description
