The utility model discloses an oil
coating device for a
brush machine, which comprises a tray on which a product is placed, and the product on the tray is driven by a lifting mechanism to move to a
processing station; a brushing
machine support and an oil spraying support are arranged on one side of the
machining station, a first adjusting mechanism is arranged on the brushing
machine support, and the first adjusting mechanism is connected with the
brush head and can adjust the vertical position and the
deflection angle of the
brush head; a second adjusting mechanism is arranged on the oil spraying support, the second adjusting mechanism is connected with the
grease valve and can adjust the front-back position of the
grease valve, an oil spraying
pipe is arranged on the
grease valve, and the oil spraying
pipe can be driven by the second adjusting mechanism to go deep into the product and spray grease to the interior of the product in the circumferential direction. By integrating machine brushing and internal oil spraying into one
station, oil spraying operation is synchronously carried out while machine brushing is carried out on the automobile gearbox, mutual interference is avoided, and the overall assembling efficiency of the automobile gearbox is greatly improved.
