Technical Problem

[0004]本发明提供一种用于方形铸件逐面刮砂清砂的耐高温八爪复合机械手，解决了现有清砂设备难以在夹持状态下对方形铸件实现稳定夹持的同时完成逐面刮砂清砂的问题

Benefits of technology

[0016] I. The high-temperature resistant eight-claw composite robotic arm for surface-by-surface sand scraping and cleaning of square castings provided by this invention, by setting up an industrial robotic arm and a gripping device in conjunction with it, allows the grippers to slide relative to the sides of the square casting while the grippers stably hold the casting. This eliminates the need for a separate sand scraping mechanism, simplifying the equipment structure, reducing process flow, and lowering manufacturing costs. The conical nozzle of the air-jet sand cleaning system is arranged towards the sand scraping area of ​​the grippers, which can blow the scraped sand particles away from the surface of the square casting and the gripping gaps in real time while the sand scraping action is in progress. This prevents residual sand from accumulating at the edges and corners of the casting, facilitating sand cleaning and improving the cleaning effect. Integrating the gripping, sand scraping, and sand cleaning functions into the same end effector, namely the gripping device, allows the square casting to be scraped and cleaned while in a sand scraping and gripping state, reducing the flow of the workpiece between different workstations, shortening the process flow, and improving production efficiency.

Abstract

The application relates to the technical field of sand cleaning equipment for castings, in particular to a high-temperature-resistant eight-claw composite manipulator for surface-by-surface sand scraping and cleaning of square castings, which comprises an industrial manipulator, a clamping device and a jet sand cleaning system; the clamping device is connected to the tail end of the industrial manipulator, the clamping device comprises a plurality of clamping claws for clamping the square castings, when the clamping claws are in a sand scraping clamping state, the industrial manipulator is controlled to move so that the plurality of clamping claws and the side surface of the square castings relatively slide to perform sand scraping, the jet sand cleaning system is arranged in the clamping space of the clamping device, the jet sand cleaning system comprises a plurality of conical nozzles, the plurality of conical nozzles are arranged on the clamping device and are arranged towards the sand scraping area of the clamping claws for sand blowing, the clamping claws and the side surface of the square castings relatively slide by controlling the movement of the manipulator, surface-by-surface sand scraping can be realized without additionally arranging a sand scraping mechanism, the equipment structure is simplified, the process flow is reduced, and the manufacturing cost is reduced.
