Description

Technical Field

[0001] The utility model relates to the technical field of electrochemical treatment, and more specifically, to an electrochemical automatic polishing device. Background Art

[0002] Electrochemical polishing is to polish the workpiece surface in a specific electrochemical polishing solution, with the workpiece to be polished as the anode and other materials as the cathode, using the principle of electrochemical reaction anode dissolution to remove burrs and microscopic unevenness on the workpiece surface, thereby improving the performance of the workpiece. Therefore, electrochemical polishing is widely used in various industries because it can level the surface of metal products without mechanical stress.

[0003] The existing polishing equipment realizes the polishing process of the workpiece as follows. First, the operator clamps the workpiece on the fixture and ensures that the fixture is connected to the anode of the power supply, and immerses the workpiece in the polishing liquid through the fixture. By loading a certain current, the workpiece immersed in the polishing liquid can be polished. However, the workpiece is clamped by the fixture. Although the workpiece can be polished and transported under the action of the fixture, when the fixture clamps the workpiece, the clamping part of the workpiece has limited contact with the polishing liquid in the polishing liquid, which affects the polishing of the clamping part of the workpiece. When the workpiece is directly thrown into the polishing equipment, the contact part between the workpiece and the polishing equipment is difficult to polish, which greatly affects the polishing efficiency of the workpiece. Utility Model Content

[0028] A carrying mechanism 10 is provided in the electrolytic cell 1. The carrying mechanism 10 is provided at the bottom of the transfer mechanism 3. The carrying mechanism 10 is used to switch the working surface of the workpiece to increase the contact area between the workpiece and the electrolyte.

[0029] The bearing mechanism 10 includes a fixed cover 11, a bearing member 12 is arranged on the top of the fixed cover 11, and a lifting bearing member 13 is arranged inside the fixed cover 11; the bearing member 12 includes a bearing plate 121, a plurality of support rods 122 are arranged on the bearing plate 121 at equal intervals, a plurality of through holes 123 are opened on the bearing plate 121, the bearing plate 121 is fixedly installed on the top of the fixed cover 11, and bearing platforms 124 are arranged on both sides of the bearing plate, and the bearing platforms 124 play a supporting role for the transfer plate 4; the bearing member 13 includes a bearing plate 121, a plurality of support rods 122 are arranged on the bearing plate 121 at equal intervals, and a plurality of through holes 123 are opened on the bearing plate 121, and the bearing plate 121 is fixedly installed on the top of the fixed cover 11, and a bearing platform 124 is arranged on both sides of the bearing plate, and the bearing platform 124 plays a supporting role for the transfer plate 4; The second carrier plate 131 is provided with a plurality of second support rods 132 at equal intervals on the second carrier plate 131, and the plurality of second support rods 132 correspond to the plurality of through holes 123 one by one. The second support rods 132 are slidably connected with the through holes 123 on the first carrier plate 121, and the first support rod 122 and the second support rod 132 are both connected with the power supply in the fixed cover 11, and the first support rod 122 and the second support rod 132 are respectively in contact with the workpiece, so that the workpiece serves as an anode and forms an electrical circuit with the cathode plate 2 in the electrolytic cell 1, thereby realizing the polishing operation of the workpiece;

[0030] The length of the second support rod 132 is greater than the length of the first support rod 122, and the radius of the first support plate 121 is greater than the radius of the second support plate 131;

[0031] A hydraulic cylinder is provided in the fixed cover 11, and the piston rod of the hydraulic cylinder is fixedly connected to the second supporting plate 131. The second supporting plate 131 is driven to rise in the fixed cover 11 by the hydraulic cylinder. When the second supporting plate 131 rises and moves to the top, the multiple second supporting rods 132 rise to the top and continue to lift the workpiece upward, so that the workpiece is separated from the first supporting rod 122.

[0032] The electrolytic cell 1 is provided with a transfer mechanism 3, which moves the workpiece and is used for transporting between the outside of the electrolytic cell 1 and the carrier mechanism 10 inside the electrolytic cell 1;

[0033] The transfer mechanism 3 includes a transfer plate 4, which is used to place the workpiece. Transfer frames 5 are arranged on both sides of the transfer plate 4. The transfer plate 4 is fixed to the transfer frame 5 by a connecting plate. Both ends of the transfer frame 5 are connected to a lifting frame 6. Electric push rods 7 are arranged on both sides of the outer wall of the electrolytic cell 1. There are four electric push rods 7 in total. The piston rod of the electric push rod 7 is fixedly connected to the lifting frame 6. The lifting frame 6 is driven to move by the electric push rod 7, thereby driving the transfer plate 4 between the two transfer frames 5 to move up and down, so that the workpiece on the transfer plate 4 can be transported from outside the electrolytic cell 1 to the supporting mechanism 10 in the electrolytic cell 1, and at the same time, the workpiece can be transported from the electrolytic cell 1 to the outside of the electrolytic cell 1, so as to realize the unloading and replacement of the workpiece; a plurality of through holes 8 for the support rod 1 122 to pass through are opened on the transfer plate 4, and a plurality of through holes 2 9 for the support rod 2 132 to pass through are also arranged on the transfer plate 4.

At this time, the workpiece is separated from the transfer plate 4 under the action of the multiple support rods 122 of the bearing plate 121. The multiple support rods 122 support the workpiece. The point contact formed by the multiple support rods 122 increases the contact area between the workpiece and the electrolyte, avoiding that the contact area between the workpiece and the fixture is too large, which affects the polishing efficiency of the workpiece;

[0036] After polishing to the set time, the hydraulic cylinder drives the supporting plate 131 to rise in the fixed cover 11. When the supporting plate 131 rises and moves to the top, the multiple supporting rods 132 rise to the top and continue to lift the workpiece upward, so that the workpiece is separated from the supporting rod 122. At this time, the surface of the workpiece continues to be polished, which improves the polishing efficiency of the workpiece and solves the problem of the fixture causing the electrolyte contact area to decrease.
