Multi-arm hanging rail type casting cleaning robot

Abstract

The invention discloses a multi-arm hanging rail type casting cleaning robot which comprises traveling devices, a rotating device, lifting devices, a working arm mounting seat and four working arms mounted on annular rails. Pneumatic grippers, magnetic cranes and cleaning tools such as pneumatic air picks and plasma cutters are arranged on tail end executors of the working arms. The traveling devices adopt four-point hanging supporting ways to realize long-distance stable traveling; large-arm adjusting cylinders and small-arm adjusting cylinders replace servo reducing motors to adjust the postures of the working arms; the four working arms can work synchronously in a combined manner; and the two pneumatic grippers, the two magnetic cranes and the four cleaning tools can be flexibly transformed and replaced, requirements of cleaning operations of recognizing, carrying, turning, posture adjusting, sand removal, cutting and polishing of heavy-weight, large-size and complicated-shaped castings can be met, the efficiency and the quality of the casting cleaning operation are improved, and the labor intensity and the production cost of operators are reduced.

Description

technical field [0001] The invention belongs to the technical field of foundry robot equipment, and in particular relates to a multi-arm suspension track type casting cleaning robot. Background technique [0002] During the casting production process, it is often necessary to move and adjust the posture of the casting, and to 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...

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 heterogeneous castings
