Inner hole electroplating processing device

The invention provides an inner hole electroplating machining device. The inner hole electroplating machining device comprises a first anode rod, a fixing lining, a shielding end cover, a first shielding sleeve, a second shielding sleeve, a second anode rod and a third shielding sleeve. Inner holes are formed in the first anode rod and the second anode rod; the second anode rod comprises a channel rod and an electroplating rod, and the channel rod penetrates through the inner hole of the first anode rod; the fixed bushing and the first shielding sleeve are located at the two ends of the first anode rod respectively, the second shielding sleeve and the third shielding sleeve are arranged at the two ends of the electroplating rod respectively in a sleeving mode, and the second shielding sleeve is arranged on the channel rod and the electroplating rod in a sleeving mode at the same time; the third shielding sleeve is arranged far away from the first anode rod; and the shielding end cover is sleeved on the first
