Abstract

The invention discloses strengthening equipment for a screw hole in an automobile part. The strengthening equipment comprises a bottom plate, a dust collecting box is fixedly connected to the upper surface of the bottom plate, a fixing plate is fixedly connected to the inner wall of the dust collecting box, a dust suction fan is fixedly connected to the lower surface of the fixing plate, a throughhole matched with an air inlet of the dust suction fan is formed in the upper surface of the fixing plate, an air outlet cover is fixedly connected to the side face of the dust collecting box, an airoutlet pipe is fixedly connected to the side face of the air outlet cover, a sleeve is fixedly connected to the end, away from the air outlet cover, of the air outlet pipe, and a dust suction cover is fixedly connected to the surface of the sleeve. According to the strengthening equipment, sand grains in a sand casting mold are sucked into the dust collecting box and filtered by filtering holes of the dust collecting box by turning on the dust collecting fan, and meanwhile, filtered air is blown into an inner cavity of the sand casting mold through a conical pipe to blow up the sand grains, so that the sand grains are cleaned more thoroughly, and sand holes caused by the sand grains are avoided, and the screw hole strength is prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field of auto parts production, in particular to a device for strengthening screw holes of auto parts. Background technique [0002] The screw hole of auto parts is a mechanism that connects two auto parts. At the same time, the screw hole is a stress point, so the strength of the screw hole must meet the requirements. [0003] At present, most auto parts belong to castings, and during the casting process, due to the incomplete cleaning of the sand around the sand mold, the inside and surface of the casting are wrapped with sand or sand blocks, and holes are formed, and the presence of sand holes in the screw holes will reduce Structural strength. [0004] Therefore, we propose a device for strengthening screw holes of auto parts. Contents of the invention [0005] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a kind of screw hole strengthening equipment of aut...
