Description

Technical Field

[0001] This utility model relates to the technical field of robotic arm-type box-flipping mechanisms, specifically a robotic arm-type box-flipping mechanism for embedding steel shot in boxes. Background Technology

[0002] The coated sand steel shot embedding box production line is an automated production line combining coated sand casting and steel shot surface treatment, mainly used for cleaning, strengthening, and surface treatment of castings. This production line is suitable for high-volume, high-efficiency casting production. During production, the workpiece and steel shot are placed together inside the embedding box. Then, a tilting device grabs the embedding box and tilts it over. However, the operation requires pre-grabbing, and then removing the entire box from the base for tilting. The grabbing process is relatively slow, and the embedding box needs to be lifted during tilting. If the clamping is unstable, the embedding box can easily fall off, causing a hazard. Therefore, improvements to the existing technology are needed. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model adds a hinged embedded box, support arm and flipping arm to the box base. When it is necessary to flip the embedded box, the flipping arm can be driven by a hydraulic cylinder to deflect. During the deflection process, the flipping arm drives the embedded box to deflect through the linkage between the support arm and the embedded box.
