The blind hole of straight position, two hole intersections, and pedestal, which are located in axis blind hole in a vertical position, has been fixedly connected on cathode rod,
Cathode rod is equipped with the through-hole coaxial with the body of rod, and the partition is fixedly connected on the top surface of pedestal, and partition is equipped with through-hole, yin
Pole bar stretches out the top surface of partition, is threaded with energization screw on partition, which is butted on cathode rod, and negative with power supply
Extremely it is connected, and is cased with spacer on the part body of rod of cathode rod stretching partition, the top surface of the spacer is lower than the top surface of cathode rod；It uses
When, the oil outlet of workpiece is placed on spacer, and is pressed on partition in workpiece by anode block, and anode block is connected with positive pole,
The top surface of cathode rod is located at the intersection of oil outlet and counterbore.
The utility model is further improved scheme, and the material of the partition and spacer is nylon.
It is that the pedestal is located at the opening for the blind hole that axis is in a horizontal position that the utility model, which is further improved scheme,
Equipped with liquid inlet joint.
The utility model is further improved scheme, and the outer diameter of the cathode rod is less than the diameter 0.6-2mm of oil outlet, institute
The diameter for stating spacer is equal to the diameter of oil outlet, and the seamed edge rounded corner at the top of spacer.Ensure to be powered in electrolyte and anode block
When, electrolysis concentrates on burr part, further ensures that burr removal is clean；The material of spacer is nylon, and spacer top
The seamed edge rounded corner in portion avoids spacer from scratching oil outlet when the oil outlet of workpiece to be placed on spacer.
The utility model compared with prior art, has the advantages that
The utility model structure is simple, and the oil outlet of workpiece is placed on spacer, and is pressed in partition by anode block in workpiece
On, it after electrolyte enters pedestal by liquid inlet joint, then is flow in the counterbore on workpiece by the through-hole on cathode rod, cathode rod connects directly
Power cathode is flowed, anode block connects DC power anode, discharges positioned at the intersection of oil outlet and counterbore, removes by electrolytic etching
The burr of valve inner infall, it is ensured that burr removal is clean, avoids workpiece after mounting because stuck caused by burr herein
Problem.
