Suspended orbit type multi-arm casting robot

Abstract

The invention discloses a suspended orbit type multi-arm casting robot which comprises a running gear, a slewing gear, a lifting gear, a working-arm mounting seat, a first working arm, a second working arm, a third working arm, a fourth working arm and a circular orbit. Cleaning tools of a pneumatic finger, a polisher, a pneumatic pick, a plasma cutter and the like are arranged on an end executor of each of the four working arms. The running gear adopts four-point suspension, long-distance steady movement of a robot can be realized, the four working arms can be operated in a joint manner, the four pneumatic fingers and the four cleaning tools can be converted flexibly, multi-tool synchronization operation can be realized, requirements on cleaning operations of recognizing, transporting, overturning, attitude adjusting, cleaning, cutting, polishing and the like of castings with heavy weight, bulk mass and complex shape can be met, efficiency and quality of casting cleaning operation are improved, and labor intensity and production cost of operating personnel are lowered.

Description

technical field [0001] The invention belongs to the technical field of foundry robot equipment, in particular to a suspension track type multi-arm foundry robot. Background technique [0002] During the casting production process, it is often necessary to move and adjust the posture of the casting, and complete various cleaning operations on the casting. In production, it is necessary not only to remove the core and core iron, but also to remove gates, risers, fleshing, tie bars, and metal residues such as cut ribs, flashes, burrs, etc., to remove sticky sand and foreign objects on the casting surface, and to polish and smooth the surface of the casting. . Most castings still mainly rely on hand tools and semi-mechanized tools such as wind punches, wind shovels, high-speed portable grinding wheels, and suspended grinding wheels. Castings with less complex shapes also use general-purpose stamping machines and sawing machines. When castings have large batches, special machin...

Problems solved by technology

The Chinese patent application number 201510512610.4 proposes a compact robot automatic grinding device, which uses a robot to grab the casting and move it to the grinding device for grinding. This type of automatic grinding device has the following disadvantages: 1) The robot has limited load capacity and cannot carry heavy castings ;2) The feed movement during the grinding process is the movement of the casting, which is not suitable for large castings

In the existing technical solutions, single-arm robots are mostly used for single-machine or multi-machine operations, which cannot meet the requirements of handling, attitude adjustment and cleaning operations of large-weight, large-volume and complex special-shaped castings
