[0002] The electrochemical machining gap monitoring and adjustment device is a key component of electrochemical machining equipment. Its function is to monitor and control the gap between the tool electrode and the workpiece to ensure machining accuracy and quality.

[0003] A search of Chinese patent CN 218612093 U reveals a machining fixture for convenient control of the inter-electrode gap. The fixture includes a base plate and a cover plate. A positioning mechanism is provided on the base plate, and the cover plate is fixed to the base plate via the positioning mechanism. A bracket is mounted on the base plate, and an adjusting bolt is rotatably mounted on the bracket. A through-hole sliding sleeve is provided in the cover plate, and an electrostatic block is fixed to the bottom end of the sliding sleeve. The sliding sleeve is threadedly connected to the adjusting bolt. An electrolytic cell is provided on the upper surface of the base plate, and an installation groove is provided in the electrolytic cell for mounting the workpiece. In this invention, the operator can determine the adjustment distance by observing the pointer's value on the scale line, simplifying the frequent comparison and adjustment process, improving the efficiency of inter-electrode gap adjustment, ensuring the accuracy of inter-electrode gap adjustment, and enhancing the electrolysis effect.

[0004] In the existing technology, the sliding sleeve and the lead-in block are fixedly installed, which makes it difficult to replace and adjust the lead-in block when electrolyzing arc-shaped or irregularly shaped workpieces. This results in uneven gaps between electrodes, affecting the electrolysis effect. Therefore, a new structure is needed to solve the above problems. Utility Model Content

To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model is a device for monitoring and adjusting the gap in electrolytic machining, comprising: An electrolytic machining gap adjustment assembly includes an electrolytic tank, a tank cover, an electric lead plate, an electro-hydraulic rod, an electric lead rod, and a connecting negative electrode. A workpiece is placed in an electrolytic cell inside the electrolytic tank. The top of the electrolytic tank is movably connected to the tank cover, and the bottom of the tank cover is movably connected to the electric lead plate. One end of the electro-hydraulic rod is fixedly connected to the middle of the tank cover, and the electric lead rod is movably connected to the tank cover. One end of the electric lead rod is fixedly connected to the negative electrode. The bottom of the electro-hydraulic rod and the electric lead rod is provided with an electric lead plate. The easily replaceable component includes a receiving lead block, a receiving groove, a guide groove, a spring, a buckle, and a slot. The receiving lead block is fixedly connected to the bottom of the electro-hydraulic rod and the lead rod. A receiving groove is opened on the lead plate, in which the receiving lead block is movably engaged. Guide grooves are opened on both sides of the receiving lead block. One end of a spring is fixedly connected to the inside of the guide groove, and the other end of the spring is fixedly connected to a buckle. Slots are opened through both sides of the lead plate, in which the buckle is movably engaged.

[0006] Furthermore, the depth of the guide groove is greater than the length of the spring.

[0007] Furthermore, the electrolytic processing gap adjustment assembly also includes bolts and a connection to the positive electrode, with a movable bolt at the bottom of the electrolytic tank, and the positive electrode being fixedly installed at the bottom of the bolt.

[0008] Furthermore, the electrolytic processing gap adjustment assembly also includes a slot and a rod, with the slot extending through the cover, the rod fixedly connected to the electrolytic box, and the rod movably connected to the slot.

[0011] Furthermore, the indicator end of the indicator rod is configured with a triangular convergent structure.

[0012] This utility model has the following beneficial effects: This invention features a movable locking mechanism between the receiving slot of the lead-in block and the lead-in plate. Furthermore, the springs and latches on both sides of the lead-in block can quickly engage with the slot of the lead-in plate for fixing or disassembly (pressing the latch compresses the spring and removes the old lead-in plate; inserting a new lead-in plate automatically engages under the spring's elasticity). This design allows operators to quickly replace lead-in plates with matching shapes based on the arc or irregular shapes of the workpieces in the electrolysis tank. This avoids uneven inter-electrode gaps caused by mismatch between the lead-in plate shape and the workpiece, ensuring uniformity in electrolytic processing from the source and improving the electrolysis effect on arc-shaped and irregularly shaped workpieces.

[0018] Please see Figure 1-4 As shown, this utility model is a device for monitoring and adjusting the gap in electrolytic machining, comprising: An electrolytic machining gap adjustment assembly includes an electrolytic tank 101, a tank cover 102, an electric lead plate 103, an electro-hydraulic rod 104, an electric lead rod 105, and a negative electrode 106. The workpiece is placed in the electrolytic cell inside the electrolytic tank 101. The top of the electrolytic tank 101 is movably connected to the tank cover 102, and the bottom of the tank cover 102 is movably connected to the electric lead plate 103. One end of the electro-hydraulic rod 104 is fixedly connected to the middle of the tank cover 102, and the electric lead rod 105 is movably connected to the middle of the tank cover 102. One end of the electric lead rod 105 is fixedly connected to the negative electrode 106. The electric lead plate 103 is provided at the bottom of the electro-hydraulic rod 104 and the electric lead rod 105. The components are easy to replace. The easy-to-replace components include a receiving lead block 201, a receiving groove 202, a guide groove 203, a spring 204, a buckle 205, and a slot 206. The bottom of the electric hydraulic rod 104 and the lead rod 105 are fixedly connected to the receiving lead block 201. The receiving groove 202 is opened on the lead plate 103. The receiving lead block 201 is movably snapped into the receiving groove 202. The receiving lead block 201 is opened on both sides. The guide groove 203 is opened on the inside of the guide groove 203. One end of the spring 204 is fixedly connected to the inside of the guide groove 203. The other end of the spring 204 is fixedly connected to the buckle 205. The slot 206 is opened through both sides of the lead plate 103. The buckle 205 is movably snapped into the slot 206. The electric hydraulic rod 104 provides kinetic energy for the up-and-down movement of the lead plate 103, the receiving lead block 201, and the lead rod 105. The receiving groove 202 ensures the initial connection of the receiving lead block 201 on the lead plate 103. The guide groove 203 ensures the movable connection of the spring 204 and the buckle 205. The spring 204 is used to realize the quick insertion and removal of the buckle 205 in the slot 206, thereby enabling the quick disassembly of the lead plate 103. This allows the lead plate 103 to be replaced with a specific shape according to the shape of the workpiece placed in the electrolytic cell inside the electrolytic box 101, ensuring the uniformity of the inter-electrode gap.

[0019] The depth of guide groove 203 is greater than the length of spring 204; The dimensional settings between the above components enable the buckle 205 to be positioned and connected within the receiving lead block 201.

[0020] The electrolytic processing gap adjustment assembly also includes bolts 107 and a positive electrode 108. Bolts 107 are movably connected to the bottom of the electrolytic box 101, and the positive electrode 108 is fixedly installed at the bottom of bolts 107. Bolt 107 and connection to the positive electrode 108 are used for introducing positive current.

[0021] The electrolytic processing gap adjustment assembly also includes a slot 109 and a rod 1010. The slot 109 is opened through the cover 102, and the rod 1010 is fixedly connected to the electrolytic box 101. The rod 1010 is movably connected to the slot 109. There are a total of four slots 109, located at the four corners of the cover 102, and a total of four rods 1010 are installed, located at the four top corners of the electrolytic box 101. The insertion rod 1010 and the slot 109 work together to ensure the installation and removal of the cover 102 and its connecting parts in the electrolysis tank 101.

[0022] It also includes a gap monitoring component, which includes a scale 301 and an indicator rod 302. The scale 301 is fixedly connected to the top of the box cover 102 and the scale 301 is fixedly connected to the side of the lead rod 105. The indicator end of the indicator rod 302 is set with a triangular convergent structure. The indicator rod 302 can move up and down with the electric lead rod 105. Then, the vertical displacement height of the electric lead plate 103 can be monitored by the numbers on the indicator scale 301. This allows for intuitive monitoring of the gap distance between the electric lead plate 103 and the workpiece, improving processing accuracy and quality.

[0023] Working Principle: The workpiece to be processed is placed into the electrolytic cell of the electrolytic tank 101. The tank cover 102 is aligned with the insertion rod 1010 at the top of the electrolytic tank 101 via the slots 109 at the four corners. The positive terminal of the external power supply is connected to the positive terminal 108 connected to the bolt 107 at the bottom of the electrolytic tank 101, and the negative terminal of the external power supply is connected to the negative terminal 106 at one end of the lead rod 105 to ensure circuit continuity. The electric hydraulic rod 104 in the middle of the tank cover 102 is activated. The electric hydraulic rod 104 pushes the bottom receiving lead block 201 and the lead plate 103 to move down synchronously. At the same time, the lead rod 105 moves down until the lead plate 103 is close to the workpiece. The position of the indicator rod 302 on the side of the lead rod 105 on the scale 301 at the top of the tank cover 102 is observed. The specific value is read through the indicator end of the triangular convergence structure to determine whether the gap between the lead plate 103 and the workpiece meets the processing requirements. If the gap meets the requirements, current is directly applied to start electrolytic processing; if the gap does not meet the requirements, the process is reversed. Continue to fine-tune the height of the lead plate 103 using the electric hydraulic rod 104 until the gap meets the standard before resuming processing. When disassembling the old lead plate, first disconnect the external power supply and stop the electric hydraulic rod 104. Press the buckles 205 in the slots 206 on both sides of the lead plate 103. The buckles 205 compress the springs 204 in the guide grooves 203 and retract into the guide grooves 203. At this time, the receiving lead block 201 disengages from the receiving groove 202, and the old lead plate 103 is removed. Remove the receiving lead block 201 from the bottom, select a matching new lead plate 103 according to the shape of the workpiece, align the receiving groove 202 of the new lead plate 103 with the receiving lead block 201 at the bottom of the electric hydraulic rod 104 and the lead rod 105 and insert it. During the insertion process, the buckle 205 pops out under the elastic force of the spring 204 and snaps into the slot 206 of the new lead plate 103 to complete the fixing of the new lead plate 103. After the installation is completed, repeat the above monitoring and adjustment steps.
