[0002] The surface of tubular galvanized parts needs to be pretreated before galvanizing. Existing galvanized parts surface pretreatment equipment usually uses grinding to make the surface of tubular galvanized parts smooth and improve the galvanizing processing quality of galvanized parts. However, grinding debris is very easy to adhere to the surface of tubular galvanized parts, reducing the treatment quality of the galvanized parts surface by the pretreatment equipment.

[0003] Example (authorization announcement number CN219430145U) A pipe electrogalvanizing pretreatment equipment includes a base, a support block is fixed on the top of the base, a top plate is fixed on the top of the support block, an adjusting motor is fixed on the side wall of the top plate, a threaded rod is fixed on the output end of the adjusting motor, the end of the threaded rod away from the adjusting motor is rotatably mounted on the inner wall of the top plate, the outer wall of the threaded rod is threadedly connected with a threaded sleeve, a cylinder is fixed on the bottom of the threaded sleeve, a grinding device is fixed on the bottom of the cylinder, and the left and right positions of the grinding device can be adjusted by starting the adjusting motor. When the pipe needs to be polished, the pipe can be placed on the placement plate, and the pipe can be quickly clamped and fixed by pushing the pipe to the left and cooperating with the clamping mechanism, the limiting mechanism and the limiting groove. However, the equipment does not consider surface cleaning of tubular galvanized parts, which reduces the pretreatment quality of the galvanized parts surface by the pretreatment equipment.
