Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, in particular to a material delivery device for centerless grinders. Background Art

[0002] During the manufacturing process, shaft parts usually need to be ground in a centerless grinder. Generally, the shaft parts are placed on the support plate between the grinding wheel and the adjusting wheel of the centerless grinder by a robot for grinding. Before the shaft parts are placed in the centerless grinder, multiple shaft parts need to be arranged and placed, and the shaft parts are placed on the support plate by a robot or a push rod. However, there are many operating steps to move the shaft parts from the loading plate to the support plate, and it takes a long time to load and unload a single shaft part.

[0003] For example, the existing patent number is CN205237729U, which is an automatic loading and unloading mechanism of a centerless grinder, including a gravity automatic loading device, which includes a tilted loading plate, the lower end of the loading plate corresponds to the feeding V-shaped slide, and the loading plate is provided with an upper stop rod and a lower stop rod. When the cylinder moves upward, the lower stop rod blocks the workpiece sliding down with gravity, and when the cylinder moves downward, the workpiece slides to the feeding V-shaped slide with gravity, and at the same time the upper stop rod falls to prevent the workpiece behind from sliding down; the feeding V-shaped slide moves forward and returns after feeding, and after processing, the ejection cylinder ejects the workpiece and drops it to the receiving slide. A downward inclined material receiving slide is arranged between the support plate and the V-shaped slide of the loading and unloading mechanism. After the workpiece falls into the V-shaped slide, it is necessary to control the V-shaped slide to move toward the support plate, and then push the workpiece into the support plate through the cylinder. However, in the process of the workpiece rolling from the loading plate to the V-shaped slide and then moving from the V-shaped slide to the support plate, there are many operation steps and a long stroke, which prolongs the overall time for the grinding of the stepped sleeve.
