Automatic cylinder sleeve casting coating spraying device

Abstract

The invention discloses an automatic cylinder sleeve casting coating spraying device which comprises a base, a spray gun support reciprocator, a spray gun support swing mechanism and a coating spraying mechanism. The spray gun support reciprocator comprises a reciprocating cylinder, a cylinder connecting push rod, a guide rod connecting plate, a thrust swing connecting seat, an upper guide rod, alower guide rod, a guide plate and a guide sleeve, the spray gun support swing mechanism comprises a swing push cylinder, a swing push rack, a rack seat, a bearing block, a turning gear and a turninggear end cover, and the coating spraying mechanism comprises a spray gun, a spray gun support, a supporting rod, an electromagnetic gas valve and an electromagnetic coating valve. Based on an existingtraditional single-station centrifugal casting machine, automation and program control of the coating spraying process are realized, the device can be independently operated and can also be subjectedto on-line operation with the casting machine with an automatic casting function, the device is stable in structure, safe and reliable, process stability of the casting quality of a cylinder sleeve is ensured, the labor intensity of workers is greatly reduced, and labor safety of the workers is guaranteed.

Description

technical field [0001] The invention belongs to the field of design and manufacture of non-standard casting equipment, and in particular relates to an automatic spraying device for cylinder liner casting paint. Background technique [0002] The coating process is an important part of the casting process, especially for the centrifugal casting of the cylinder liner. The coating not only affects important physical performance indicators such as metallography and hardness of the cylinder liner, but also has a significant impact on the casting quality. At the same time, when the cylinder liner is poured quantitatively, the thickness, uniformity and stability of the coating layer directly affect the geometric dimension accuracy of the blank of the cylinder liner. In the domestic cylinder liner industry, since single-station centrifugal casting machines are generally used at present, and manual pouring is adopted, the coating is mainly carried out manually. There are two main meth...

AI Technical Summary

Problems solved by technology

Due to the influence of artificial factors, the situation of unstable coating dosage and uneven coating layer often occurs in actual production, which directly affects the pass rate of blanks. At the same time, because the mold is in a rotating state during coating, there are potential safety hazards and unsafe factors. Situations that lead to work-related injuries happen from time to time

At present, the most advanced technology in the world is to use a multi-station centrifugal casting machine and integrate it into the automatic paint spraying unit. This method requires a large investment in equipment, which can cost several million to tens of millions of yuan; second, it is applied to small varieties and large batches. The production mode is not suitable for the production mode of many varieties of small and medium-sized batches of manufacturers in many industries
