[0041] Refer to Figures 1 to 4 As shown, an electrolytic tooling for deburring of the present utility model is applied to a part 100 having a transfer hole 120 and a middle hole 110. The part 100 includes opposite first and second ends. One end of the middle hole 110 penetrates through the first end of the part 100, and both ends of the transfer hole 120 are respectively connected to the middle hole 110 and penetrate through the second end of the part 100; the electrolytic tooling includes:
[0042] A positioning block 1, which is internally provided with a positioning hole 11 and an electrolyte channel 12 that communicate with each other;
[0043] A limiting component 2 for limiting the part 100 on the positioning block 1;
[0044] The electrolysis core 3 is disposed within the positioning hole 11. The electrolysis core 3 can extend into the middle hole 110 along the first end of the part 100. An electrolyte flow region communicating with the middle hole 110 is formed between the outer side of the electrolysis core 3 and the positioning hole 11.
[0045] Wherein, after the electrolyte is introduced through the electrolyte channel 12, it can flow through the electrolyte flow region, the middle hole 110, and the connection hole 120 in sequence, and finally flow out from the connection hole 120.
[0046] In one embodiment, the electrolysis core 3 includes an electrolysis core rod 31 and an electrolysis sheath 32 sleeved outside the electrolysis core rod 31.
[0047] Specifically, the middle hole 110 includes a first section 110a connected to the connection hole 120 and a second section 110b connected to the first section 110a and penetrating through the first end of the part 100. After the electrolysis core rod 31 extends into the middle hole 110, the electrolysis sheath 32 can cover the electrolysis core rod 31 located within the second section 110b. The electrolysis sheath 32 can protect the waist groove (i.e., the second section 110b) in the lower region of the connection hole 120 from being electrolyzed.
[0048] In one embodiment, the electrolysis core rod 31 has a solid structure. A polyoxymethylene sheath is installed at the top of the electrolysis core rod 31 to prevent the part 100 from contacting the electrode and avoid the occurrence of short circuit; the electrolysis sheath 32 is made of polyoxymethylene material.
[0049] In one embodiment, the electrolyte channel 12 extends on the side wall of the positioning block 1, and a connector 13 communicating with the electrolyte channel 12 is installed on the side wall of the positioning block 1.
[0050] In one embodiment, a support seat 4 is further included to support the lower end of the positioning block 1. A core seat 5 is disposed between the support seat 4 and the positioning block 1, and the core seat 5 supports the bottom end of the electrolysis core rod 31.
[0051] In the existing electrolysis fixture, generally, the electrolyte connector 13 is installed on the support seat 4, the electrolyte hole is connected to the bottom of the core seat 5, and the electrolysis core rod 31 has an axial hole by itself, and a through spraying hole is opened at the head, and the electrolyte is sprayed out through the hollow electrolysis core rod 31. However, it is found during the test that it is very difficult to electrolyze the connection hole 120 in the part 100. Due to the too small connection hole 120 in the part 100, and the axial hole of the electrolysis core rod 31 can only be made 1.5 mm, the water output of the electrolyte is insufficient. Although most of the burrs can be removed, the burrs at the upper end of the connection hole 120 of the part 100 cannot be electrolyzed cleanly.
[0052] By making the electrolyte spray out from the gap (electrolyte flow area) between the outer side of the electrolyte core 3 and the positioning hole 11, the electrolyte water output can be significantly increased, and the deburring effect can be improved.
[0053] In one embodiment, the electrolytic sheath 32 includes a first section 321, a second section 322 and a third section 323 whose diameters decrease successively along the direction approaching the center hole 110, a positioning groove is formed between the core seat 5 and the positioning block 1, the first section 321 cooperates with the positioning groove, an electrolyte injection area is formed between the second section 322 and the positioning hole 11 of the positioning block 1, and the third section 323 can extend into the center hole 110 to protect the lower area of the intersection hole 120 and ensure the dimensional accuracy and surface quality of the part 100.
[0054] It should be noted that the first section 321 ensures the position of the positioning sleeve, and the diameter of the second section 322 needs to be small enough to provide a larger electrolyte spraying area.
[0055] In one embodiment, the core seat 5 includes a receiving hole 51 for the electrolytic core rod 31 to extend and slide into, and the core seat 5 is connected with an adjusting screw 52 that abuts against the side wall of the electrolytic core rod 31 to adjust the height of the electrolytic core rod 31 and tighten the electrolytic core rod 31. The height and tightening degree of the electrolytic core rod 31 can be adjusted by adjusting the screw 52, so that the equipment can achieve the best working state under different working conditions.
[0056] In one embodiment, a base 6 is installed at the bottom of the core seat 5, and the base 6 is used to connect to the electrolytic machine tool; the core seat 5, the base 6 and the positioning block 1 are all made of stainless steel, which improves the stability and corrosion resistance of the tooling and extends the service life of the equipment.
[0057] In one embodiment, the limiting assembly 2 includes a pressure plate 21, columns 22 arranged on both sides of the pressure plate 21, and a pressure head 23 arranged in the middle of the pressure plate 21. The plurality of intersection holes 120 are distributed circumferentially along the axis of the center hole 110. After the column 22 is supported on the top of the positioning block 1, the pressure head 23 can abut against the second end of the part 100 and is located in the center of the plurality of intersection holes 120.
[0058] Since the pressure head 23 of the electrolytic machine is very large, and the top surface of the part 100 has a compressible range of only 8 mm, the intersection hole 120 with a diameter of 2 mm on the top surface must be exposed while being pressed to facilitate the discharge of the electrolyte. By setting a pressure plate 21 and adding a pressure head 23 with a diameter of 6 mm on the pressure plate 21, it can be ensured that the electrolyte is discharged smoothly.
[0059] In one embodiment, the top of the positioning block 1 is provided with (four) inclined flow channels 14 for discharging the electrolyte in the circumferential direction of the component 100, so as to discharge the electrolyte quickly.
[0060] When in use, the second end of the part 100 to be deburred is placed downward on the positioning block 1 of the electrolysis tooling, and the part 100 is limited and fixed by the pressing plate 21, the column 22 and the pressing head 23 in the limiting assembly 2;
[0061] The electrolytic core rod 31 is extended into the middle hole 110 along the first end of the component 100, and an electrolyte flow area is formed between the electrolytic sheath 32 and the positioning hole 11;
[0062] The electrolyte is introduced through the joint 13 and enters the positioning block 1 from the electrolyte channel 12. The electrolyte flows in from the joint 13 on the side wall of the positioning block 1, and flows through the middle hole 110 and the intersection hole 120 in sequence through the electrolyte flow area, and finally flows out from the second end of the component 100;
[0063] Under the action of the electrolyte, the burrs on the surface of the interface hole 120 are effectively removed. The electrolysis sheath 32 protects the lower area of the interface hole 120 from being electrolyzed, ensuring the accuracy of the electrolysis process;
[0064] The height and tightening degree of the electrolytic core rod 31 can be adjusted by the adjusting screw 52 on the core holder 5 to ensure that the electrolytic core rod 31 works at the best position;
[0065] The electrolyte is quickly discharged through the inclined flow channel 14 at the top of the positioning block 1, ensuring the smooth flow of the electrolyte and preventing the accumulation of liquid from affecting the deburring effect.
[0066] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
