In the oxidation treatment process, as the surface of the workpiece grows a modified ceramic coating which takes the matrix metal oxide as a main component and takes the electrolyte component in the solution tank 1 as an auxiliary component, the electrolyte concentration at the periphery of the workpiece in the solution tank 1 gradually decreases, and in order to keep the high efficiency of the oxidation treatment of the workpiece, the electrolyte at the periphery of the workpiece needs to be promoted to flow along with the progress of the oxidation treatment so as to ensure the electrolyte concentration at the position of the station.
As shown in fig. 9 and 10, one end of the limiting component is further provided with a cylindrical adjusting cylinder 27 on the mounting hole 26, the adjusting cylinder 27 and the connecting piece 22 are coaxially arranged, an adjusting groove 271 is formed in the inner wall of the adjusting cylinder 27, the adjusting groove 271 is wavy on the circumference side of the inner wall of the adjusting cylinder 27, a piston head 222 is axially arranged in the connecting piece 22 in a sliding manner, a piston rod 223 is fixed on the piston head 222, the free end of the piston rod 223 extends into the adjusting cylinder 27 and is slidably assembled with the adjusting groove 271, specifically, the end of the piston rod 223 is provided with a movable rod 224, the movable rod 224 is slidably connected with the adjusting groove 271, so that when the driving source 3 drives the clamping block 25 to clamp a workpiece to rotate, the connecting piece 22 synchronously rotates along with the workpiece, the piston rod 223 rotates along the adjusting groove 271 through the movable rod 224, the piston rod 223 is further pushed to reciprocate in the connecting piece 22 under the action of the adjusting groove 271, through holes are formed in the end of the connecting piece 222 and the connecting piece 22, the end of the supporting seat 221 is fixedly provided with a through hole, and two through holes are respectively provided with one-way valves, and the two one-way valves are opened only when electrolyte in the solution tank 1 enters the connecting piece 22;
when the connecting piece 22 rotates synchronously with the workpiece, the piston rod 223 pushes the piston head 222 to slide back and forth in the connecting piece 22, and pumps electrolyte with relatively low concentration near the supporting seat 221 into the connecting piece 22 and discharges the electrolyte to one end of the connecting piece 22 far away from the supporting seat 221 from the through hole on the piston head 222, namely, the electrolyte with relatively low concentration near the workpiece is pumped away from the position far away from the workpiece, so that the flow of the electrolyte at the periphery of the workpiece is promoted, the replenishment of the electrolyte with high concentration at the periphery of the workpiece is promoted, and the oxidation treatment speed and the treatment effect of the workpiece are improved.
