[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] See also Figures 1 to 4 As shown, according to an embodiment of the present application, a polymer electrode clamp is provided, including a clamping body 1 and a chuck 2, the chuck 2 having a receiving hole for passing a plurality of electrode wires 3, and a locking hole is provided at one end of the clamping body 1 close to the chuck 2. When the chuck 2 moves into the locking hole, the hole wall of the locking hole applies a radial force to the chuck 2 so that the chuck 2 clamps the plurality of electrode wires 3.

[0028] In the present application, a locking hole is provided on the clamping body 1. When the chuck 2 moves into the locking hole, the hole wall of the locking hole applies radial force to the chuck 2 so that the chuck 2 can clamp a plurality of electrode wires 3 as electrodes for electrospark machining, thereby shortening the preparation time of the electrodes for electrospark machining and improving the machining efficiency, thereby shortening the product delivery cycle and improving production efficiency.

[0029] The polymer electrode fixture may be an electrode fixture for electric spark machining.

[0030] Specifically, in the embodiment of the present application, the electrode includes a plurality of electrode wires 3, and electrodes of different shapes can be formed by the plurality of electrode wires 3. It should be noted that, compared with the integral electrode, the electrode composed of the plurality of electrode wires 3 does not need to be processed into different shapes according to different requirements of different workpieces to be processed, that is, the shape design of the integral electrode and the finishing steps of the integral electrode are optimized, and the purpose of shortening the electrode preparation time can be achieved.

[0031] Among them, the electrode wire 3 can be a copper rod, a graphite rod or a brass rod, etc., and this application does not make further limitations. In the embodiment of this application, the electrode wire 3 is a graphite rod.

[0032] The workpiece to be processed may be a part with a complex shape that is difficult to process by traditional machining. For example, the workpiece to be processed is a three-dimensional impeller.

[0033] Among them, the polymer electrode fixture includes a clamping body 1, which is roughly stepped. The clamping body 1 includes a first section 11, a second section 12 and a third section 13. The second section 12 is arranged between the first section 11 and the third section 13. The third section 13 is used to connect with the oil flushing pipe, and the second section 12 is used to connect with the machine tool spindle. A locking hole is opened in the middle of the first section 11, and the locking hole is used to load the electrode. The locking hole can be a rectangular hole or a cylindrical hole, etc. This application does not make further limitations. In the embodiment of this application, the locking hole is a cylindrical hole.

[0034] Specifically, as one embodiment, the clamping body 1 is manufactured in one piece; as another embodiment, the clamping body 1 is composed of a first section 11, a second section 12 and a third section 13 fixedly connected, and the connection method can be bolt connection or welding, etc., and this application does not make further limitations.

[0035] The polymer electrode fixture further comprises a clamp 2, and a receiving hole is provided in the middle of the clamp 2 for accommodating a plurality of electrode wires 3. In the present application, a stable setting position is provided for the plurality of electrode wires 3 by providing the receiving hole, and the plurality of electrode wires 3 are arranged through the receiving hole.

[0036] The chuck 2 is retractable, and the working state of the chuck 2 includes a first state and a second state. The first state may be an initial state, and the second state may be a retracted state.

[0037] Among them, when the chuck 2 is in the first working state, the inner diameter of the chuck 2 is greater than the inner diameter of the chuck 2 when the chuck 2 is in the second working state. When the chuck 2 switches from the first state to the second state, the diameter of the receiving hole decreases, so that several electrode wires 3 can be clamped.

[0038] Specifically, when the chuck 2 is in the first state, the chuck 2 is filled with a plurality of electrode wires 3, and the maximum outer diameter of the chuck 2 is greater than the diameter of the locking hole; when the chuck 2 is in the second state, the maximum outer diameter of the chuck 2 is the same as the diameter of the locking hole, and the chuck 2 is used to clamp a plurality of electrode wires 3. It should be noted that when the chuck 2 moves into the locking hole, the chuck 2 switches from the first state to the second state, and the inner diameter of the chuck 2 gradually decreases. When the chuck 2 is fully inserted into the locking hole, the chuck 2 is subjected to a radial force exerted by the hole wall of the locking hole, so that the chuck 2 is fixed in the second state, thereby achieving the purpose of clamping a plurality of electrode wires 3.

[0039] In some possible implementations provided in this application, see Figure 3 As shown, the receiving hole is cylindrical.

[0040] By setting the receiving hole to be cylindrical, so that several electrode wires 3 form surface contact or line contact with the inner wall of the receiving hole, it is ensured that several electrode wires 3 are subjected to uniform force, and several electrode wires 3 can fill the receiving hole, avoiding the situation where several electrode wires 3 still shake after clamping, thereby improving the stability of electrospark machining.

[0041] In the embodiment of the present application, the electrode wire 3 is cylindrical. By setting the receiving hole to be cylindrical, it is beneficial for the clamp 2 to contract and clamp a plurality of electrode wires 3.

[0042] In some possible implementations provided in this application, see Figure 3 As shown, the clamp 2 includes a first clamp body 21 and a second clamp body 22 , the first clamp body 21 is arranged on the first direction side of the second clamp body 22 , and the outer diameter of the first clamp body 21 gradually decreases along the first direction.

[0043] The first direction may be the direction in which the chuck 2 moves toward the locking hole of the clamping body 1 , and the first direction side may be the side where the clamping body 1 is located when the chuck 2 moves toward the locking hole of the clamping body 1 .

[0044] As one embodiment, the chuck 2 is integrally manufactured; as another embodiment, the chuck 2 is formed by a first chuck body 21 and a second chuck body 22 fixedly connected, and the connection method can be bolt connection or welding, etc., which is not further limited in this application. In the embodiment of this application, the chuck 2 includes a first chuck body 21 and a second chuck body 22.

[0045] Specifically, the first clamp body 21 is arranged on a side of the second clamp body 22 close to the clamping body 1, and the first clamp body 21 is roughly conical. The outer diameter of one end of the first clamp body 21 close to the clamping body 1 is less than or equal to the diameter of the locking hole, and the outer diameter of the first clamp body 21 gradually decreases in the direction close to the clamping body 1.

[0046] The second clamp 22 is coaxially arranged with the first clamp 21, and the inner diameter of the second clamp 22 is the same as that of the first clamp 21. As an embodiment, the second clamp 22 is cylindrical; as another embodiment, the second clamp 22 is conical, and the outer diameter of the second clamp 22 gradually decreases in the direction away from the clamping body 1. In the embodiment of the present application, the second clamp 22 is conical, and the outer diameter of the second clamp 22 gradually decreases in the direction away from the clamping body 1. It can be understood that the intersection of the first clamp 21 and the second clamp 22 is the location of the maximum outer diameter of the chuck 2. The chuck 2 can also include a third chuck coaxially arranged with the first chuck 21 and the second chuck 22. The third chuck is arranged between the first chuck 21 and the second chuck 22. The third chuck can be cylindrical. In this case, the outer diameter of the cylindrical third chuck is the maximum outer diameter of the chuck 2. The third chuck is used to increase the contact area between the chuck 2 and the hole wall of the locking hole to improve the uniformity of the force on the chuck 2 and ensure that several electrode wires 3 can be clamped, thereby improving the stability of electrospark machining.

[0047] In the present application, by setting the outer diameter of one end of the chuck 2 close to the clamping body 1 to gradually decrease in the direction toward the clamping body 1, it is convenient to insert the chuck 2 into the locking hole, that is, to switch the chuck 2 from the first state to the second state, thereby improving work efficiency and shortening the electrode preparation time.

[0048] In some possible implementations provided in this application, see Figure 3 As shown, a plurality of first contraction seams 23 and a plurality of second contraction seams 24 are respectively provided at both ends of the chuck 2, and the plurality of first contraction seams 23 and the plurality of second contraction seams 24 are alternately arranged along the circumferential direction of the chuck 2 and penetrate the chuck 2 along the radial direction of the clamping body 1. When the chuck 2 moves into the locking hole, the gaps between the plurality of first contraction seams 23 and the plurality of second contraction seams 24 are reduced.

[0049] By respectively opening a plurality of first shrinkage slits 23 and a plurality of second shrinkage slits 24 at both ends of the chuck 2, and making the plurality of first shrinkage slits 23 and a plurality of second shrinkage slits 24 penetrate the chuck 2 in the radial direction of the clamping body 1 and extend in the axial direction of the clamping body 1, so that the inner diameter of the chuck 2 is adjustable, the chuck 2 can be shrunk and moved into the locking hole, thereby clamping a plurality of electrode wires 3.

[0050] Among them, a plurality of first shrinkage seams 23 penetrate the first clamping body 21 along the axial direction of the clamping body 1 and extend to the second clamping body 22 along the axial direction of the clamping body 1 , but do not penetrate the second clamping body 22 .

[0051] Among them, a plurality of second shrinkage seams 24 penetrate the second clamping body 22 along the axial direction of the clamping body 1 and extend to the first clamping body 21 along the axial direction of the clamping body 1 , but do not penetrate the first clamping body 21 .

[0052] Specifically, a plurality of first contraction seams 23 and a plurality of second contraction seams 24 are evenly and alternately distributed in the circumferential direction at the position where the maximum outer diameter of the chuck 2 is located. It should be noted that when the chuck 2 moves into the locking hole of the clamping body 1, the chuck 2 is deformed, the maximum outer diameter of the chuck 2 is reduced, and the gaps between the plurality of first contraction seams 23 and the plurality of second contraction seams 24 are reduced, so that the inner diameter of the chuck 2 is reduced, that is, the diameter of the receiving hole is reduced, so that the plurality of electrode wires 3 filled in the receiving hole can be clamped.

[0053] In addition, the chuck 2 can also be arranged as follows:

[0054] A third shrinkage seam is provided on the outer wall of the chuck 2 , and the third shrinkage seam penetrates the chuck 2 in the radial direction and the axial direction of the clamping body 1 . When the chuck 2 moves into the locking hole, the gap of the third shrinkage seam is reduced.

[0055] By opening a third shrinkage seam on the chuck 2 and allowing the third shrinkage seam to penetrate the chuck 2 in the axial and radial directions of the clamping body 1 at the same time, so that the inner diameter of the chuck 2 is adjustable, the chuck 2 can be shrunk and moved into the locking hole, thereby clamping a plurality of electrode wires 3.

[0056] Among them, only one third shrinkage seam is provided, and the third shrinkage seam passes through the first clamp body 21 and the second clamp body 22 along the axial direction of the clamp body 1 at the same time. At this time, the cross section of the clamp head 2 perpendicular to the central axis of the clamp body 1 is roughly C-shaped.

[0057] Specifically, when the chuck 2 moves into the locking hole of the clamping body 1, the chuck 2 is deformed, the maximum outer diameter of the chuck 2 is reduced, and the gap of the third shrinkage seam is reduced, so that the inner diameter of the chuck 2 is reduced, that is, the diameter of the receiving hole is reduced, so that several electrode wires 3 filled in the receiving hole can be clamped.

[0058] In some possible implementations provided in this application, see Figure 4 As shown, the polymer electrode clamp further includes a fixing member 4, which is disposed on the opposite side of the first direction of the clamp 2, and is connected to the clamping body 1, and is used to limit the clamp 2 in the opposite direction of the first direction.

[0059] By providing the fixing member 4, the chuck 2 can be limited in the direction of the chuck 2 toward the workpiece to be processed, thereby preventing the chuck 2 from escaping from the locking hole of the clamping body 1, thereby improving the stability of the electrospark machining.

[0060] The fixing member 4 can be threadedly connected to the end of the first section 11 of the clamping body 1 to prevent the clamp 2 from falling out of the locking hole.

[0061] Specifically, a stopper 41 is provided on the inner wall of the end of the fixing member 4 away from the clamping body 1, and the inner diameter of the stopper 41 gradually decreases in the direction close to the chuck 2, and the minimum inner diameter of the stopper 41 is smaller than the diameter of the locking hole, that is, the minimum inner diameter of the stopper 41 is smaller than the maximum outer diameter of the chuck 2 when it is in the second state. It should be noted that after the fixing member 4 is tightened on the clamping body 1, the stopper 41 is located on the outer peripheral side of the second clamp 22, and at this time, the end of the stopper 41 close to the second clamp 22 abuts against the outer wall of the second clamp 2, which can achieve the purpose of limiting the chuck 2 from coming out of the locking hole.

[0062] In some possible implementations provided in this application, see Figure 1 and Figure 2 As shown, the polymer electrode fixture further includes a rotating seat 5 and a fixed seat 6. The rotating seat 5 is sleeved on the clamping body 1. The first end of the fixed seat 6 is used to connect to the rotating seat 5, and the second end of the fixed seat 6 is used to connect to the driving shaft.

[0063] By providing the rotating seat 5 and the fixing seat 6, the clamping body 1 can be connected to the driving shaft to achieve C-axis positioning of the EDM.

[0064] The C-axis may be an axis that rotates around the Z-axis.

[0065] Specifically, the Z axis can be a machine tool spindle, that is, the C axis can be an axis that rotates around the axis of the machine tool spindle. The C axis can be divided into 360 degrees, and the clamping body 1 can make the chuck 2 and several electrode wires 3 accurately rotate to the required degree through the cooperation of the rotating seat 5 and the fixed seat 6, such as C180.0 or C150.0.

[0066] The middle of the rotating seat 5 is provided with a mounting hole, through which the clamping body 1 can penetrate the rotating seat 5.

[0067] Specifically, the third section 13 of the clamping body 1 can be interference-fitted with the mounting hole to achieve relative fixation of the clamping body 1 and the rotating seat 5 .

[0068] Among them, the top of the rotating seat 5 is connected to the first end of the fixed seat 6, and the second end of the fixed seat 6 is used to connect the drive shaft, which can be a machine tool spindle, that is, the fixed seat 6 is used to connect the machine tool spindle and the rotating seat 5.

[0069] Specifically, the first end of the fixing seat 6 may be an end of the fixing seat 6 away from the main shaft of the machine tool, and the second end of the fixing seat 6 may be an end of the fixing seat 6 close to the main shaft of the machine tool.

[0070] In some possible implementations provided in this application, see Figure 2 As shown, the first end of the fixed seat 6 is rotatably connected to the rotating seat 5 .

[0071] By setting the rotating seat 5 and the fixed seat 6 to be rotatably connected, the clamping body 1 can rotate with the rotating connection point of the rotating seat 5 and the fixed seat 6 as the rotation center, which can realize rapid adjustment of the angle between several electrode wires 3 and the workpiece to be processed, thereby improving work efficiency.

[0072] The first end of the fixed seat 6 can be rotatably connected to the rotating seat 5 via a rotating connector.

[0073] Specifically, the rotating connecting member can be a bolt, an ear plate is provided on the top of the rotating seat 5, and two parallel clamps are provided on the first end of the fixed seat 6. The spacing between the two clamps matches the thickness of the ear plate, and matching screw holes are provided on the ear plate and the two clamps. The first end of the fixed seat 6 is connected to the ear plate on the top of the rotating seat 5 by clamping the two clamps and rotating through the bolt through the screw hole.

[0074] The clip has scales on it to indicate the rotation angle of the rotating seat 5 .

[0075] In some possible embodiments provided in the present application, an adapter 7 is provided at the second end of the fixing seat 6, and the adapter 7 is used to connect the driving shaft.

[0076] By providing the adapter 7, the fixing seat 6 can be quickly connected to the machine tool spindle, thereby improving the working efficiency.

[0077] The adapter 7 may be a connection key or the like.

[0078] Specifically, the adapter 7 is disposed between the fixing seat 6 and the main shaft of the machine tool, one end of the adapter 7 is connected to the fixing seat 6, and the other end is connected to the main shaft of the machine tool.

[0079] In some possible implementations provided in this application, see Figure 1 and Figure 2As shown, the polymer electrode fixture further includes an oil spray nozzle 8, which is connected to one end of the clamping body 1 away from the clamp 2, and is used to fix the oil flushing pipe. The oil spray nozzle 8 has an oil cavity, which is connected to the locking hole.

[0080] By providing the oil injection nozzle 8 with a stable setting position for the oil flushing pipe, continuous and uninterrupted oil flushing to the workpiece to be processed can be achieved, the removal of electro-erosion products can be accelerated, the EDM conditions can be improved, and the EDM speed and EDM stability can be increased.

[0081] The oil spray nozzle 8 is arranged at an end of the clamping body 1 away from the workpiece to be processed.

[0082] Specifically, the oil spray nozzle 8 is connected to the third section 13 of the clamping body 1, and the connection method can be bolt connection. It should be noted that the oil spray nozzle 8 has an oil cavity, which is connected to the locking hole, and the oil flushing pipe flushes oil to the workpiece through the oil cavity and the connected locking hole.

[0083] The polymer electrode clamp provided in the present application includes a clamping body 1 and a chuck 2. A locking hole is provided on the clamping body 1. When the chuck 2 moves into the locking hole, the hole wall of the locking hole applies a radial force to the chuck 2 so that the chuck 2 can clamp a plurality of electrode wires 3 as electrodes for electrospark machining, thereby shortening the preparation time of electrodes for electrospark machining and improving machining efficiency, thereby shortening the product delivery cycle and improving production efficiency.

[0084] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.
