A casting cleaning unit and cleaning method

Abstract

The invention discloses a casting cleaning unit which comprises a casting transit exchange mechanism. The casting transit exchange mechanism comprises a bottom support, an exchange platform, an upper support, a drive device and a positioning device. The positioning device comprises an installation plate and at least two ejecting rods. The installation plate is connected to the power output end of the drive device. The upper ends of the ejecting rods are connected to the installation plate. The lower ends of the ejecting rods are right opposite to the exchange platform. A robot system comprises a first robot and a second robot. The first robot is arranged on the feed side of the casting transit exchange mechanism. The second robot is arranged on the discharge side of the casting transit exchange mechanism. The casting cleaning unit is suitable for automatic unit product price multi-procedure conditions, reliable and stable in positioning, suitable for positioning castings of various types, and suitable for being shared by various product parts; the mechanism is simple in structure, low in manufacturing cost and high in cost performance. The invention further discloses a casting cleaning method.

Description

technical field [0001] The invention relates to the field of casting, in particular to a casting cleaning unit and a cleaning method. Background technique [0002] After the casting is poured, it enters the cleaning process of the casting after unpacking, sand shakeout and shot blasting. Burrs on the parting surface of castings, ingates and riser neck residues are unavoidable structures in castings, especially in special-shaped castings. These structures are not needed by customers and must be cleaned and ground. In the past, castings were cleaned completely. Relying on manual grinding, the work efficiency is extremely low, the working environment is harsh, the labor cost is high and the labor force is strong. In the process of manual cleaning and grinding of castings, special-shaped castings need to be cleaned in many parts, the structure is thick, and it is very difficult to clean and grind.

Problems solved by technology

Burrs on the parting surface of castings, ingates and riser neck residues are unavoidable structures in castings, especially in special-shaped castings. These structures are not needed by customers and must be cleaned and ground. In the past, castings were cleaned completely. Relying on manual grinding, the work efficiency is extremely low, the working environment is harsh, the labor cost is high and the labor force is strong

In the process of manual cleaning and grinding of castings, special-shaped castings have many parts to be cleaned, and the structure is thick, so it is very difficult to clean and grind. The daily quota of workers is very low; there is no strict standard for cleaning, and the dimensions of the castings are very different from personal grinding standards. Great relationship, customer complaints due to the quality of castings often occur; the grinding machine, polishing disc, and grinding head required for cleaning and grinding are very expensive; the structure of special-shaped castings is complex, and there are many parts that need to be cleaned, and workers need to constantly carry castings Only by changing the angle can it be cleaned; the fine dust generated by the grinding is scattered throughout the workshop, seriously affecting the health of workers; more importantly, the safety of workers cannot be guaranteed
