Electrolytic polishing cathode for inner hole of deep and long tube

Abstract

The invention discloses an electrolytic polishing cathode for an inner hole of a deep and long tube. The electrolytic polishing cathode is used for solving the technical problem that an existing innerhole electrolytic polishing cathode is poor in practicability. According to the technical scheme, the electrolytic polishing cathode comprises a cathode body, a water sealing washer, a front guide body, centering O-shaped sealing rings, a cathode body annular groove section, a flow-dividing O-shaped sealing ring, a rear guide body, a back-pressure rubber washer and a screw cap; the cathode body serves as a centre shaft, and the left end of the cathode body is connected to the cathode body annular groove section and the rear guide body in a threaded mode, is sleeved with the back-pressure rubber washer and then is tightly pressed with the screw cap; the right end of the cathode body is connected to the front guide body in a threaded mode and is sleeved with the water sealing washer; the flow-dividing O-shaped rubber ring and the two sets of centering O-shaped sealing rings are arranged in annular grooves corresponding to the front guide body, the rear guide body and the cathode body annular groove section; the threaded bonding surfaces of the front guide body, the rear guide body and the cathode body are coated with adhesives so as to be connected; and a multi-wire spiral groove section in the cathode body and a annular groove section body in the cathode body annular groove section form an electrolytic working area. The multi-wire spiral groove section in the cathode body and the cathode body annular groove section provide electrolyte separately, and therefore the smoothness of the inner hole of the deep and long pipe can be improved, and the practicability is good.

Description

technical field [0001] The invention relates to an inner hole electrolytic polishing cathode, in particular to a deep and long tube inner hole electrolytic polishing cathode. Background technique [0002] refer to image 3 , Figure 4 . The electrolytic polishing process of the inner hole of the deep and long tube is used in various industries, especially the processing of artillery barrels, which can effectively improve the life of the barrels. Over the years, most of them have used straight cylindrical or tapered cathodes for electrolytic machining. image 3 , Figure 4 It is a typical structure of this type of cathode, consisting of A cathode body 10, a coil 11, A front guide 12, an O-ring 13, A rear guide 14 and a rear cover 15. The main defects of this type of cathode are: (1) The development of the electrolytic working surface is essentially flat end face feeding, and it is difficult to eliminate the knife marks left by machining. Therefore, the requirements for the...
