Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to a cleaning device for an external cylindrical grinding machine. Background Technique

[0002] As an important device in the field of metal processing, the external cylindrical grinding machine is widely used in the machining and manufacturing of precision mechanical parts such as bearings, crankshafts, and gears; during the grinding process, due to the friction between the high-speed rotating grinding wheel and the workpiece, a large amount of metal powder will be generated.

[0003] At present, in order to prevent deformation or burning of the workpiece caused by overheating during grinding, the external cylindrical grinding machine is usually equipped with a cooling system to cool the workpiece by spraying cooling water; however, when the oil stain formed by metal powder and lubricating oil mixes into the cooling water, it will significantly reduce the cleanliness of the cooling water, and then easily block the drain pipe, affecting the normal operation of the cooling system; at the same time, the direct discharge of the cooling water containing metal powder will not only pollute the environment, but also cause waste of water resources.

[0004] Therefore, it is very necessary to propose a cleaning device for the cooling water of the external cylindrical grinding machine to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the above technical deficiencies, propose a cleaning device for an external cylindrical grinding machine, and solve the technical problems proposed in the background technique.

The spraying mechanism is arranged above the grinding wheel of the grinding machine; the collecting tank is inclined and arranged below the grinding wheel of the grinding machine; the cleaning mechanism is arranged at the lower end of the collecting tank, and a circulating mechanism is arranged below the cleaning mechanism. The circulating mechanism connects the cleaning mechanism and the spraying mechanism; the cleaning mechanism includes a frame, a cleaning support and a filter screen support are arranged on the frame, a detachable filter screen is arranged on the filter screen support, a confluence tank is arranged on the filter screen support below the filter screen, the lower end of the confluence tank is connected with the circulating mechanism, a translation guide rail is arranged on the cleaning support, and the translation guide rail drives the scraping mechanism arranged on its slider to reciprocate horizontally. The scraping mechanism cooperates with the filter screen.

[0007] Further, the scraping mechanism includes a lifting support plate. At the top of the lifting support plate, there are two lifting cylinders. On the piston rod of the lifting cylinder, there is a scraping support bracket. The scraping support bracket is slidably connected to the lifting support plate.
