Description

Technical Field

[0001] This utility model relates to the technical field of fitness equipment manufacturing equipment, and in particular to a counterweight plate drilling processing device. Background Technology

[0002] Weight plates are detachable weights used to adjust the load level of equipment, commonly used in fitness equipment and weightlifting training. Weight plates used in fitness equipment are typically made of PU rubber or cast iron, and generally weigh 2.5 kg or more. They are used to adjust the load on the equipment. In plate-type fitness equipment, the weight plates are usually fixed inside the equipment, and different weight combinations are achieved through adjusting the positions of the pins and holes. Plate-type fitness equipment weight plates are generally cuboid. In the production process of these weight plates, drilling is required. However, current drilling processes generally require workers to manually position the plates, operate tools to drill, and remove burrs. The processing time for a single plate is long, affecting production efficiency. Furthermore, manual drilling has poor precision, easily causing deviations in concentricity and perpendicularity, resulting in poor appearance consistency of the weight plates, and jeopardizing worker safety.
