DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The content of the present utility model will be further described in detail below in conjunction with specific embodiments:

[0023] Such as Figure 1As shown in the figure, a wire electrolytic polishing device includes an electrolytic cell 1 with a rectangular structure. The electrolytic cell 1 contains electrolyte, and an electrolytic frame 2 for fixing the wire is arranged above the electrolytic cell 1. Driven by a lifting device 3, the electrolytic frame 2 carries the wire into the electrolyte. Moreover, the electrolytic frame 2 is connected to a power source, enabling the wire immersed in the electrolyte to conduct electricity, thereby carrying out an electrolytic reaction and polishing the wire.

[0024] As Figure 2 shown in the figure, the electrolytic frame 2 is set to have a rectangular structure and is respectively composed of a first frame body 21 arranged in parallel and a pair of second frame bodies 22 arranged perpendicular to the first frame body 21. A through hole 23 for the wire to pass through is coaxially opened in a pair of first frame bodies 21, and a chuck 4 is installed at one end of any first frame body 21 close to the other first frame body 21 and corresponding to the through hole 23 for straightening and fixing the wire. In this embodiment, both the through hole 23 and the chuck 4 are arranged in parallel in the length direction of the first frame body 21 as multiple, so that an electrolytic frame 2 can carry multiple wires and perform electrolytic polishing on them, improving work efficiency. In addition, the tail of the chuck 4 is embedded in the through hole 23, and the head serves as a clamping end and can rotate around its own axis driven by a motor, thereby driving the wire to rotate and electrolyze simultaneously during electrolytic operation, making the polishing more uniform.

[0025] In order to enable the wire to be electrified, both the first frame body 21 and the chuck 4 installed thereon are made of conductive materials such as stainless steel. The second frame body 22 has no conductive requirement and can be made of insulating materials.

[0026] As Figure 4 shown in the figure, the lifting device 3 includes a gantry 31 erected in the electrolytic cell 1. There are two gantries 31, and any gantry 31 has a horizontal section 311 at the top and vertical sections 312 on both sides. A guide rail 32 slider 33 mechanism composed of a guide rail 32 and a slider 33 is installed on the vertical section 312. Among them, the guide rail 32 is fixed on the vertical section 312 in the vertical direction, the slider 33 is slidably matched with the guide rail 32 and fixed to the second frame body 22 of the electrolytic frame 2, and the electrolytic frame 2 makes a lifting movement along the guide rail 32 driven by an external driving device connected thereto.

[0027] After the wire is electrolytically polished, its diameter needs to be measured to determine whether the coating thickness on the wire after electrolytic polishing meets the standard. Therefore, a diameter measuring device 5 is installed on the gantry 31 corresponding to each wire.

[0028] As Figure 3As shown, the diameter measuring device 5 includes a support rod 51 vertically installed below the horizontal section 311 of the gantry 31. A measuring head 52 is installed at one end of the support rod 51 away from the horizontal section 311. An opening is provided at one end of the measuring head 52 away from the support rod 51, so that the measuring head 52 forms a C-shaped structure. The measuring head 52 moves up and down driven by the electrolysis frame 2, so that the wire passes in and out through the opening, thereby measuring the diameter of the wire.

[0029] During use:

[0030] 1. Pass the wire to be electro-polished through a pair of first frames 21, and clamp and fix both ends thereof on the chuck 4.

[0031] 2. Electrify the first frame 21 to make the wire charged. Then start the lifting device 3 to immerse the electrolysis frame 2 in the electrolyte in the electrolytic cell 1. At the same time, the chuck 4 drives the wire to rotate around the axis to realize electrolysis while rotating.

[0032] 3. After a certain period of time, raise the electrolysis frame 2 and send the wire into the measuring head 52 of the diameter measuring device 5 to detect whether the diameter of the wire after electro-polishing meets the requirements. If not, repeat the above steps.
