Description

Technical Field

[0001] The utility model belongs to the technical field of industrial part processing and cleaning, and specifically relates to an automatic degreasing and cleaning system for workpieces. Background Art

[0002] During the processing of metal workpieces, auxiliary materials such as cutting fluid, coolant or lubricating oil are usually used to cool or lubricate the surface of the workpieces. These materials may adhere to the surface of the metal workpieces, forming oil stains, which will hinder the adhesion between the coating and the metal surface during painting, resulting in coating peeling or being insecure. Cleaning can remove the oil stains on the surface, ensure that the coating can firmly adhere to the metal, improve the adhesion and durability of the painting. It can also eliminate surface impurities and dirt, ensure that the purity of the metal surface meets the requirements, and can also reduce the risk of corrosion and oxidation, and extend the service life of the metal workpieces. Therefore, it is necessary to design an automatic degreasing and cleaning system for workpieces. Summary of the Invention

[0003] The purpose of the utility model is to provide an automatic degreasing and cleaning system for workpieces, which can automatically degrease, passivate and clean the workpieces efficiently and energy-savingly.

[0004] An automatic degreasing and cleaning system for workpieces, the key points are: including an annular conveying mechanism, below which there are multiple cleaning pools with different heights connected in series in a gradient manner. The workpiece hanging frame chain of the annular conveying mechanism can extend into the cleaning pools. There is a common partition wall between adjacent cleaning pools, and a water injection port is opened on the upper end surface of the partition wall to connect adjacent cleaning pools. The water injection port of the previous stage is higher than that of the next stage. The first-stage cleaning pool is provided with a water inlet faucet, and the last-stage cleaning pool is provided with a water outlet. A sewage outlet is provided at the bottom of each cleaning pool, and a degreasing and passivation pool is arranged near the last-stage cleaning pool. With the above structure, the workpieces to be processed are hung on the workpiece hanging frame chain through workpiece support frames, etc. After the annular conveying mechanism runs, the workpieces are first degreased and passivated in the degreasing and passivation pool, and then are successively cleaned from the last-stage clean water pool to the first-stage clean water pool. In this way, the cleaning sequence of the workpieces is opposite to the flowing direction of the water in the clean water pools. The relatively clean workpieces are cleaned in the relatively clean clean water pools, thus greatly saving the water consumption and saving water resources; at the same time, using the annular conveying mechanism for workpiece transmission greatly improves the efficiency of degreasing, passivating and cleaning the workpiece surface.

[0005] Preferably: each cleaning pool is of a cube structure, and the adjacent water injection ports are diagonally distributed, so that the effective replenishment of water between the previous-stage clean water pool and the next-stage clean water pool can be greatly improved.

[0006] Preferably: the annular conveying mechanism includes a support beam, an annular ring beam, a transmission chain, a sprocket and a workpiece hanging frame chain;

[0007] The annular ring beam is connected below the support beam. A T-shaped groove is formed in the annular ring beam. The transmission chain is installed in the groove. The transmission chain meshes with a sprocket installed inside the annular ring beam. The workpiece hanging frame chains are evenly installed on the transmission chain.

[0008] Preferably, it further includes a degreasing and passivating mechanism. The degreasing and passivating mechanism includes a workpiece support frame and a hollow tray for lifting the workpiece support frame. The hollow tray is connected to a lifting mechanism. The hollow tray is located directly above the degreasing and passivating tank.

[0009] Preferably, a first transfer robotic arm and a second transfer robotic arm are arranged on one side close to the degreasing and passivating tank. The first transfer robotic arm is used to place the workpiece support frame on the hollow tray, and the second transfer robotic arm hangs the hollow tray on the workpiece hanging frame chain.

[0010] Preferably, the lifting mechanism includes a support platform. A lifting hydraulic cylinder is fixed on the support platform. The cylinder body of the lifting hydraulic cylinder is fixed on the support platform. The piston rod of the lifting hydraulic cylinder extends downward out of the support platform. The extending end of the piston rod of the lifting hydraulic cylinder is connected to a "Z"-shaped bracket. The upper horizontal part of the bracket is connected to the piston rod of the lifting hydraulic cylinder, and the lower horizontal part of the bracket supports the hollow tray. The selection of the above structure greatly improves the automation degree of workpiece degreasing and passivation and improves work efficiency.

[0011] Benefits of the present utility model: It can realize automatic degreasing cleaning or passivation cleaning of workpieces, improve production efficiency, and reduce water usage costs and sewage treatment costs. BRIEF DESCRIPTION OF THE DRAWINGS
