Description

Technical Field

[0001] This utility model belongs to the field of electrolytic machining cathode technology, and in particular relates to a modular electrolytic machining cathode tool that can be quickly replaced. Background Technology

[0002] Cylindrical cathodes, such as cylindrical cathode tools with a uniform diameter, have an outer cylindrical surface of the same diameter and are commonly used in electrolytic drilling. The outer and inner diameters, bottom thickness, and overall length can be designed according to specific machining requirements. To reduce electrolyte outflow resistance, chamfers can be provided at the junction of the side and bottom surfaces.

[0003] Because conventional cathodes are clamped or loosened by screws, the clamps need to be loosened little by little with a screwdriver during operation. After replacing the cathode, they also need to be tightened little by little, which makes the installation or removal of conventional cathodes relatively slow.

[0004] To address this issue, we propose a modular electrolytic machining cathode tool that can be quickly replaced. Utility Model Content

[0005] The purpose of this invention is to solve the problem of slow conventional cathode installation or disassembly operations by proposing a modular electrolytic machining cathode tool that can be quickly replaced.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A modular electrolytic machining cathode tool with quick-change features includes a spring clamp with a constraint sleeve slidingly fitted on its outer side. A cathode is inserted inside the spring clamp. When the cathode is inserted into the spring clamp, the constraint sleeve is squeezed downwards, tightening the spring clamp inwards and firmly securing the cathode. Lifting the constraint sleeve upwards releases the constraint at the lower part of the spring clamp, reducing the clamping force on the cathode, allowing the cathode to be pulled out downwards for easy and quick cathode replacement.

[0007] Preferably, the elastic clamp includes an elastic clamp body, and a guide nozzle is fixedly connected to the lower end of the elastic clamp body. The elastic clamp body and the guide nozzle are an integral structure. The guide nozzle guides the cathode into the elastic clamp body, and the elastic force of the elastic clamp body pre-clamps the cathode, facilitating the pre-fixation of the cathode.

[0008] Preferably, the upper part of the elastic clip body has a first locking groove. The first locking groove is used to hold the constraint sleeve in a high position to avoid obstructing the insertion of the cathode.

[0009] Preferably, a second locking groove is provided at the lower part of the elastic clamp body. The second locking groove is used to fasten the constraint sleeve, keeping the constraint sleeve in a low position and improving the stability of the elastic clamp and cathode clamping state.

[0010] Preferably, the constraint sleeve includes a constraint ring, with a spring piece fixedly connected to the upper part of the constraint ring, and a fastening block fixedly connected to the upper part of the spring piece. The fastening block engages with the first fastening groove and the second fastening groove respectively. By using the fastening block to engage in the first fastening groove, the constraint sleeve is kept in a high position, ensuring stability when the spring clip is released. After the constraint sleeve is pushed down, the fastening block engages in the second fastening groove, keeping the constraint sleeve in a low position, improving the stability of the locked state, and facilitating changes to and stabilizing the locked or released state.

[0011] Preferably, the constraint sleeve further includes a pinch button, which is symmetrically and fixedly connected to the side of the constraint ring. Squeezing the pinch button actuates the constraint ring, facilitating manual operation of the constraint sleeve.

[0012] Preferably, the cathode includes a cathode body, and a guide head is provided at the upper end of the cathode body. The guide head is used to guide the cathode into the elastic clamp body.

[0013] In summary, the technical effects and advantages of this utility model are as follows: 1. Insert the cathode into the spring clamp, squeeze the constraint sleeve and pull it down to tighten the spring clamp inward, so that the spring clamp firmly clamps and fixes the cathode; lift the constraint sleeve upward to remove the constraint at the bottom of the spring clamp, thereby reducing the clamping force on the cathode, and pull the cathode downward to facilitate quick cathode replacement.

[0014] 2. The cathode is guided into the body of the elastic clamp using the guide nozzle. The elastic force of the elastic clamp body is used to pre-clamp the cathode, which facilitates the pre-fixation of the cathode.

[0015] 3. Use the buckle to fasten the first buckle groove to keep the constraint sleeve in a high position, ensuring the stability of the released elastic clip state. After pushing the constraint sleeve down, use the buckle to fasten the second buckle groove to keep the constraint sleeve in a low position, improving the stability of the locked state and making it easier to change and stabilize the locked or loosened state.

[0018] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0019] As shown in the figure, a modular electrolytic machining cathode tool with quick replacement includes a spring clamp 2, a constraint sleeve 3 slidingly fitted on the outside of the spring clamp 2, and a cathode 4 inserted inside the spring clamp 2. When the cathode 4 is inserted into the spring clamp 2, the constraint sleeve 3 is squeezed downwards, causing the constraint sleeve 3 to tighten the spring clamp 2 inwards, firmly clamping and fixing the cathode 4. Lifting the constraint sleeve 3 upwards removes the constraint from the lower part of the spring clamp 2, thereby reducing the clamping force on the cathode 4, allowing the cathode 4 to be pulled downwards.

[0020] As shown in the figure, the elastic clamp 2 includes an elastic clamp body 21, and a guide nozzle 22 is fixedly connected to the lower end of the elastic clamp body 21. The elastic clamp body 21 and the guide nozzle 22 are an integral structure. The guide nozzle 22 guides the cathode 4 into the elastic clamp body 21, and the elastic force of the elastic clamp body 21 pre-clamps the cathode 4.

[0021] As shown in the figure, the upper part of the elastic clamp body 21 is provided with a first fastening groove 23. The first fastening groove 23 is used to fasten the constraint sleeve 3, keeping the constraint sleeve 3 in a high position and avoiding obstruction of the insertion of the cathode 4.

[0022] As shown in the figure, a second locking groove 24 is provided at the lower part of the elastic clamp body 21. The second locking groove 24 is used to fasten the constraint sleeve 3, keeping the constraint sleeve 3 in a low position and improving the stability of the clamping state of the elastic clamp 2 and the cathode 4.

[0023] As shown in the figure, the constraint sleeve 3 includes a constraint ring 33, with a spring piece 31 fixedly connected to the upper part of the constraint ring 33, and a fastener 32 fixedly connected to the upper part of the spring piece 31. The fastener 32 engages with the first fastener slot 23 and the second fastener slot 24 respectively. The fastener 32 engages with the first fastener slot 23 to keep the constraint sleeve 3 in a high position, ensuring stability when the spring clip 2 is released. After the constraint sleeve 3 is pushed down, the fastener 32 engages with the second fastener slot 24 to keep the constraint sleeve 3 in a low position, improving the stability of the locked state.

[0024] As shown in the figure, the constraint sleeve 3 also includes a pinch button 34, which is symmetrically and fixedly connected to the side of the constraint ring 33. Squeezing the pinch button 34 exerts force on the constraint ring 33.

[0025] As shown in the figure, the cathode 4 includes a cathode body 41, and a guide head 42 is provided at the upper end of the cathode body 41. The guide head 42 is used to guide the cathode 4 into the elastic clamp body 21.

[0026] Working principle: Insert the cathode 4 into the elastic clamp 2, squeeze the constraint sleeve 3 and pull it down. The constraint sleeve 3 tightens the elastic clamp 2 inward, so that the elastic clamp 2 firmly clamps and fixes the cathode 4. Lift the constraint sleeve 3 upward, so that the lower part of the elastic clamp 2 loses its constraint, thereby reducing the clamping force of the elastic clamp 2 on the cathode 4, and pull the cathode 4 downward.

[0027] The above description is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed by the utility model, based on the technical solution and the utility model concept, should be included within the protection scope of the utility model.

[0028] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
