[0020] Depend on Figure 1 , Figure 2 and Figure 3This invention discloses an electrolytic polishing device for the inner wall of a stainless steel pipe. A support frame 101 is uniformly fixedly connected to the top wall of an electrolytic cell 100, facilitating the support of support rollers 102. Support rollers 102 are fixedly connected to the left and right sides and the front and rear sides of the top wall of the support frame 101, providing support for the steel pipe raw material. The support rollers 102 are made of conductive material, facilitating power conduction and subsequent electrolytic operations. A fixed frame 103 is fixedly connected to the top wall of the electrolytic cell 100, supporting an electric push rod 104. The electric push rod 104 is fixedly connected to the top wall of the fixed frame 103, facilitating the lifting of a lifting frame 105. The lifting frame 105 is slidably connected to the front and rear side walls of the inner cavity of the fixed frame 103, facilitating the lifting of a lifting frame 105. The limiting roller 106 is adjusted for lifting. The telescopic end of the electric push rod (104) is fixedly connected to the top wall of the lifting frame (105). The limiting roller 106 is evenly fixedly connected to the bottom wall of the lifting frame 105. The limiting roller 106 facilitates the clamping and limiting of the steel pipe raw material. The right end of the limiting roller 106 is rotatably connected to the first sprocket 107. The first sprocket 107 facilitates the rotation of the limiting roller 106. The top wall of the lifting frame 105 is fixedly connected to the drive motor 108. The drive motor 108 facilitates the rotation of the second sprocket 109. The output end of the drive motor 108 is fixedly connected to the second sprocket 109. The second sprocket 109 facilitates the rotation of the chain 110, which in turn facilitates the rotation of the first sprocket 107. The outer walls of the first sprocket 107 and the second sprocket 109 are both provided with chains 110. An electrolysis mechanism 111 is provided on the right side of the electrolysis cell 100.

[0021] In this embodiment: Electrolyte is injected into the inner cavity of the electrolytic cell 100, and the steel pipe is placed on the support roller 102. The lifting frame 105 is moved by the electric push rod 104, and the limiting roller 106 is moved by the lifting frame 105. The limiting roller 106 cooperates with the support roller 102 to clamp and limit the steel pipe. The second sprocket 109 is rotated by the drive motor 108, and the chain 110 of the second sprocket 109 is rotated. The chain 110 drives the first sprocket 107 to rotate, and the first sprocket 107 drives the limiting roller 106 to rotate. The limiting roller 106 drives the steel pipe to rotate, so that the electrolyte is evenly distributed on the inner wall of the steel pipe, which is convenient for subsequent electrolytic polishing. The device can easily rotate and adjust the clamped steel pipe to make the electrolyte evenly distributed on the inner wall of the steel pipe, which is beneficial for uniform electroplating and polishing.

[0022] The electrolysis mechanism 111 includes a connecting frame 112, which is fixedly connected to the front side wall of the electrolytic cell 100. The connecting frame 112 facilitates the support of the push screw 113. The push screw 113 is rotatably connected to the left and right side walls of the inner cavity of the connecting frame 112. The push screw 113 drives the moving frame 115 to move and adjust. A drive motor 114 is fixedly connected to the front side wall of the electrolytic cell 100. The drive motor 114 facilitates the rotation of the push screw 113. The output end of the drive motor 114 is connected to the right end of the push screw 113. The moving frame 115 is screwed to the outer wall of the push screw 113. The moving frame 115 facilitates the movement of the conductive rod 116. The conductive rod 116 is uniformly fixedly connected to the left side wall of the moving frame 115, which facilitates the conduction of electricity.

[0023] In this embodiment: the drive motor 114 drives the push screw 113 to rotate, the push screw 113 drives the moving frame 115 to move, and the moving frame 115 drives the conductive rod 116 to move. The conductive rod 116 is inserted into the inner cavity of the steel pipe. The positive terminal of the power supply is connected to the support roller 102, and the negative terminal of the power supply is connected to the conductive rod 116. After the power is turned on, the inner wall of the steel pipe is electrolytically polished. This makes it easier for the device to uniformly electroplat and polish the inner wall of the steel pipe, improves the electrolysis rate, and enhances the practicality of the device.

[0024] An insulating sleeve 117 is fixedly connected to the outer wall of the conductive rod 116. The insulating sleeve 117 facilitates the insulation of the right side wall of the conductive rod 116. A pusher plate 118 is provided on the left side of the outer wall of the conductive rod 116.

[0025] In this embodiment: by setting an insulating sleeve 117 to block the right side of the conductive rod 116, the left end of the conductive rod 116 is made conductive. The conductive rod 116 is moved by the moving frame 115. When it moves into the inner cavity of the steel pipe, the conductive rod 116 drives the push plate 118 to move. The push plate 118 pushes the electrolyte and the gas generator in the inner cavity of the steel pipe, so that all the gas in the steel pipe is discharged, avoiding the gas bubbles from affecting the contact between the electrolyte and the inner wall of the steel pipe. The moving frame 115 moves the conductive rod 116 slowly to carry out electrolysis. This allows the device to easily and evenly electrolyze and polish the inner wall of the steel pipe, avoiding the electrolyte from fully contacting the inner wall of the steel pipe, and ensuring that the current is evenly electrolyzed on the inner wall of the steel pipe.

[0026] A slide 119 is fixedly connected to the rear side wall of the electrolytic cell 100. The slide 119 facilitates the limiting and guiding of the movement of the movable frame 115, which is located on the outer wall of the slide 119.

[0027] In this embodiment: the slide 119 facilitates the support of the movable frame 115, and the slide 119 facilitates the limiting and guiding of the movement of the movable frame 115, which is beneficial for driving the conductive rod 116 to perform translational adjustment, which is convenient for subsequent electrolysis operations.

[0028] The outer wall of the limiting roller 106 is fixedly connected with anti-slip sleeves 120 to prevent slippage. The anti-slip sleeves 120 are made of rubber for support.

[0029] In this embodiment, the anti-slip sleeve 120 is set to facilitate the rotation of the steel pipe body, avoid slippage of the steel pipe during transmission, and promote uniform electrolysis operation, thereby improving electrolysis efficiency.
