[0005] An electrolytic marking device comprises an electrolytic marking head and an electrolyte box. A leakage plate is arranged on the electrolyte box, the leakage plate covers part of the electrolyte, the electrolytic marking head dips the electrolyte in the electrolyte box and drains the electrolyte on the leakage plate of the electrolyte box; the electrolytic marking head comprises a marking electrode, the marking electrode is connected to a handle through a transfer rod, a through hole is arranged at the center of the handle, a wire I connected to the negative pole of the electrolytic marking instrument passes through the through hole and enters the threaded hole at the center of the top of the transfer rod, and the wire is pressed by a screw, and a wire II of the positive pole of the electrolytic marking instrument is connected to a part to be marked.

[0006] The leakage holes are evenly distributed on the leakage plate.

[0011] The outer side of the handle is provided with an anti-slip groove, and the handle is made of nylon material.

[0012] A method for using an electrolytic marking device is implemented based on the above structure and specifically includes the following steps:

[0013] Step 1: Pour an appropriate amount of electrolyte into the electrolyte box;

[0014] Step 2: Fix the conductive cotton on the marking electrode through the stainless steel wire, connect the marking electrode to the transfer rod, pass the wire through the through hole of the handle into the threaded hole of the transfer rod, and tighten it with screws, then connect the external thread at the end of the transfer rod with the internal thread at the end of the handle, so as to complete the installation of the electrolytic marking head;

[0015] Step 3: Connect the positive lead II of the electrolytic marking instrument to the part to be marked, and wipe the marking position on the part to be marked with a cloth;

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] The lead wire on the electrolytic marking head of the existing electrolytic marking device is directly connected to the electrode, and the handle is directly installed on the electrode. Since the electrolyte is corrosive, the lead wire and the handle are corroded by the electrolyte after a period of use, which affects the conductivity of the electrolytic marking head. The marking is unclear and easy to fall off. At the same time, there is no special electrolyte box, and the electrolytic head is in a soaking state for a long time, which shortens the service life. Moreover, the electrodes on the electrolytic marking head are mostly made of graphite material. Although the conductivity is excellent, the graphite is brittle and often falls off during use.

[0032] Based on this, the present application proposes an electrolytic marking device and a method of use, which can effectively meet the marking requirements of aero-engine components, reduce the frequency of electrode replacement, improve the quality of marking, and avoid production site management problems and quality problems caused by unclear marking.

[0033] like Figures 1 to 4As shown, an electrolytic marking device comprises an electrolytic marking head 2 and an electrolyte box 1. The electrolyte box 1 is provided with a leakage plate 101, and leakage holes 102 are evenly distributed on the leakage plate. The leakage plate 101 covers part of the electrolyte. The electrolytic marking head 2 dips the electrolyte in the electrolyte box 1 and drains the electrolyte through the leakage holes 102 on the leakage plate 101 of the electrolyte box 1; the electrolytic marking head 2 comprises a marking electrode 203, the marking electrode 203 is made of red copper material, and a conductive cotton mounting slot is provided on the marking electrode 203. The conductive cotton 201 is wrapped on the surface of the marking electrode 203 through the conductive cotton mounting slot and fixed by a stainless steel wire 202;

[0034] The marking electrode 203 is connected to the handle 206 through the adapter rod 204, and the adapter rod 204 is fixedly connected to the internal thread at the end of the handle 206 through the external thread at the end; a through hole is provided in the center of the handle 206, and the wire I3 connected to the negative pole of the electrolytic marking instrument 5 passes through the through hole into the threaded hole at the center of the top of the adapter rod 204, and the wire is tightened by the screw 205, and the wire II4 of the positive pole of the electrolytic marking instrument 5 is connected to the part to be marked 6, and the conduction path is the part to be marked 6→conductive cotton 201→marking electrode 203→adapter rod 204→wire I3→electrolytic marking instrument 5.

[0035] In this embodiment, the transfer rod 204 is made of corrosion-resistant stainless steel, the handle 206 is made of nylon, and an anti-slip groove is provided on the outer side of the handle 206 .

[0036] A handle 103 is provided on the top of the electrolyte box 1 to facilitate moving the electrolyte box 1 .

[0039] Step 2: The conductive cotton 201 is fixed on the marking electrode 203 through the stainless steel wire 202, the marking electrode 203 is connected to the transfer rod 204, the wire I3 passes through the through hole of the handle 206 and enters the threaded hole of the transfer rod 204, and is fastened by the screw 205, and then the end external thread of the transfer rod 204 is connected with the end internal thread of the handle 206, thereby completing the installation of the electrolytic marking head 2;

[0040] Step 3: Connect the positive lead II 4 of the electrolytic marking instrument 5 to the part to be marked 6, and wipe the marking position on the part to be marked 6 with a cloth;

[0041] Step 4: Dip the marking electrode 203 of the electrolytic marking head 2 into the electrolyte in the electrolyte box 1 to ensure that the conductive cotton 201 is fully soaked, and place the marking electrode 203 on the leakage plate 101 to drain for about 5 seconds to ensure that the electrolyte does not drip;

[0042] Step 5: Paste the wax paper with the marking information on the part 6 to be marked;

[0043] Step 6: Place the electrolytic marking head 2 on the wax paper and press it gently, and the current will automatically turn on;

The marking electrode on the electrolytic marking head is replaced once every six months on average, which saves electrode replacement and repair costs.
