Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing, and particularly relates to a chip discharging device for a drilling machine. Background Technique

[0002] Steel structure fittings are a kind of fittings composed of steel materials through welding, riveting or bolt connection. When producing steel structure fittings, it is generally necessary to reserve an appropriate number of holes at specific positions of the steel structure through a drilling machine to facilitate subsequent installation operations. When installing large steel structure fittings, due to the large volume and complex installation operations of some steel structures, it is very difficult to pre-set installation holes, and sometimes it is necessary to perform temporary hole opening operations according to the cooperation of on-site parts. The existing chip discharging device collects iron chips to prevent them from falling into the workshop, making it difficult for subsequent workers to clean.

[0003] To solve the above problems, a chip cleaning device has emerged. For example, the Chinese utility model patent with the publication number CN214871124U discloses an automatic chip cleaning device for a PCB drilling machine, including a chip cleaning device arranged on the drilling machine table. The chip cleaning device includes a base arranged on the drilling machine table, a chip cleaning channel, a chip cleaning bin and a ventilation channel arranged on the base. The ventilation channel is connected to the chip cleaning bin, the chip cleaning bin is connected to the chip cleaning channel, the chip cleaning channel is externally connected to a chip cleaning pipe, a chip collecting box is arranged at the bottom of the chip cleaning pipe, a mesh sleeve is arranged in the chip collecting box, the mesh sleeve is connected to the chip cleaning pipe, and a chip leakage hole is arranged at the top of the chip cleaning bin. Compared with the prior art, the generated chips of the present utility model can be transported to the chip collecting box through gas, making the layout of the drilling machine body more beautiful. Moreover, it is manually operated. Compared with adding some chip cleaning mechanical structures to the drilling machine body, the structure of the drilling machine body is relatively simple, the operation is more convenient, and it does not require operators to have high technical qualities, and the practicability is better. When collecting iron chips, the above device blows the iron chips into the chip collecting box. However, due to the spiral structure of the iron chips, it is easy to cause them to hang on the side wall or bottom wall of the chip cleaning bin with a large amount of iron chip slag adhered. Therefore, a chip discharging device for a drilling machine is proposed to solve the above problems. Content of the Utility Model
