Although ultrasonic cleaning is used to remove surface metal and non-metal particles after machining, some parts have complex structures, with internal holes intersecting with end face grooves. Burrs are easily generated at the intersection edges of such structures, and it is difficult to remove such burrs through ultrasonic waves.

[0030] Embodiment:
[0031] This embodiment introduces an electrochemical anode head structure for deburring.
[0032] As shown in the attached Figure 1 、 2 figures, Figure 1 is a schematic diagram of an electrochemical anode head structure for deburring of the present utility model, Figure 2 and Figure 2
[0033] is a schematic diagram of the part in the preferred embodiment. An electrochemical anode head structure for deburring includes: a conductive substrate 1 and a conductive base material 2. One end of the conductive substrate 1 is fitted and installed together with the anode head base, and the other end is connected to the conductive base material 2 by interference fit;
[0034] An insulating substrate 3 is sleeved outside the conductive base material 2;
[0035] An electrolyte inlet hole 3-1 is opened on the outer circumference of the insulating substrate 3. The electrolyte inlet hole 3-1 corresponds to the electrolytic generation hole 7-1 on the part 7, and the electrolyte flows into the electrolytic generation hole 7-1 through the electrolyte inlet 3-1. In this way, the electrolyte smoothly flows into the position where electrochemical discharge is required, smoothly passes through the burr position, ensuring the optimization of the deburring effect of electrochemical corrosion.The part 7 is in contact with one end of the conductive substrate 2. When in contact, the end face of the conductive substrate 2 covers the central hole of the part 7 to prevent the electrolyte from flowing into the central hole, thereby ensuring the flow rate at the position where the electrolyte is required.
[0036] In this embodiment, the conductive matrix 1 is processed from corrosion-resistant stainless steel material, and the structure and size of the upper half of the conductive matrix are matched with the anode head base. The conductive substrate 2 is made of inert platinum material with high temperature resistance and corrosion resistance.
[0037] In this embodiment, the conductive matrix and the conductive substrate are in interference fit, and the current is transmitted to the conductive substrate and the part through the conductive matrix.
[0038] As Figure 3 shown, Figure 3 It is a schematic diagram of the insulating matrix in an electrochemical anode head structure for deburring according to the present utility model. A central hole 3-2 is provided along the axis of the insulating matrix 3, and the conductive substrate 2 is inserted into the central hole 3-2, and a clearance fit is formed between the conductive substrate 2 and the insulating matrix 3. The conductive substrate is wrapped in the insulating matrix, avoiding electrolytic burns when the electrolyte flows to the conductive substrate. In this embodiment, the thickness of the insulating layer of the insulating matrix 3 is 0.7 mm. The insulating matrix also plays a role in preventing the loss of the electrolyte, thereby optimizing the deburring effect.
[0039] Furthermore, the number of the electrolyte inlet holes 3-1 is four, and they are symmetrically arranged along the axis of the insulating matrix 3, such as symmetrically arranged up and down and left and right.
[0040] As Figure 4 、 5 shown, Figure 4 It is another perspective schematic diagram of an electrochemical anode head structure for deburring according to the present utility model, Figure 5 It is a schematic diagram of the pin hole in an electrochemical anode head structure for deburring according to the present utility model. A spring 4 is provided between the first step of the insulating matrix 3 and the conductive matrix 1.
[0041] Furthermore, a pin hole 5 is provided at one end of the conductive matrix 1 where it is connected to the conductive substrate 2, and the pin hole 5 corresponds to the electrolyte inlet hole 3-1.
[0042] Furthermore, the pin hole 5 corresponds to two of the symmetric electrolyte inlet holes 3-1 on the insulating matrix 3, and a pin 6 passes through the corresponding pin hole 5 and electrolyte inlet hole 3-1 to connect the insulating matrix 3 and the conductive matrix 1.
[0043] In this embodiment, the conductive substrate, the conductive base material, and the insulating substrate are connected together through springs, pin holes, and pins, and the insulating substrate can move up and down relative to the conductive substrate and the conductive base material under the coordination of the above connection relationship.
[0044] In this embodiment, the working process of using the anode head structure to remove burrs on parts is briefly described. During operation, part 7 is fixed in the cathode head seat, and the overall structure of the anode head moves from top to bottom. The insulating substrate 3 first contacts part 7. As the overall structure of the anode head continues to move downward, the spring 4 is compressed, and the conductive substrate 1 moves downward until the conductive substrate 2 contacts the end surface of part 7. At this time, the cathode head and the anode head form a circuit, and then with the electrolyte, the discharge deburring process of the part can be completed. After the process is completed, the overall structure of the anode head moves upward, the spring 4 returns to its position, and the insulating substrate 3 returns to its original position.
[0045] As attached Figure 6 , Figure 6 The schematic diagram of the threaded hole in the electrochemical anode head structure for deburring of the utility model is as follows: The end of the conductive substrate 1 connected to the anode head base is provided with a threaded hole 1-1, and the anode head electrical terminal is tightened through the threaded hole 1-1.
[0046] Furthermore, a sealing ring groove 1-2 is reserved on the conductive substrate to prevent the electrolyte from leaking into the equipment of the anode head seat and corroding or even burning the equipment substrate.
[0047] The electrochemical anode head structure for deburring introduced above has a simple structure. When used, it can effectively remove burrs on parts without damaging the structure of the anode head itself. By opening an electrolyte inlet hole on the insulating substrate, the electrolyte can flow smoothly into the electrolysis generating hole on the part. The electrolyte flows through the power to produce an electrochemical reaction, corroding the workpiece material to achieve the effect of removing burrs. The insulating substrate also protects the conductive substrate, avoiding the problem of electrolytic burns after the electrolyte flows to the conductive substrate. At the same time, because the end face of the conductive substrate covers the central hole of the part, the electrolyte will not flow to other places of the part. The electrolyte can flow to the position where electrochemical discharge is required at a larger flow rate, so that the effect of electrochemical corrosion deburring is optimal. Through the design of the electrochemical anode head structure, there will be no electrolyte on the contact surface between the conductive substrate head and the part, and no oxide will appear on the conductive substrate head, thereby reducing the work of regular grinding and cleaning by personnel, improving production efficiency, and achieving the effect of continuous production.
[0048] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
