Description

Technical Field

[0001] This utility model relates to the field of electrical discharge machining, and in particular to a three-way rapid positioning copper electrode clamp for an EDM machine. Background Technology

[0002] Traditional EDM machines require repeated calibration of the X / Y / Z axes when clamping copper electrodes, and repositioning is necessary every time the electrode is changed, resulting in cumbersome and time-consuming operations. Existing fixtures lack multi-directional linkage adjustment structures, leading to low processing efficiency. Therefore, a three-directional rapid positioning copper electrode fixture for EDM machines is proposed. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] A three-way rapid positioning copper electrode clamp for an EDM machine includes a clamp body, a first hook disposed on one side of the clamp body, a first movable block and a second movable block that translate on the other side of the clamp body, and the clamp body is further provided with a clamp handle that connects it to the EDM machine spindle. The second movable block is provided with a second hook that moves synchronously with it and clamps the copper electrode together with the first hook. The first movable block is provided with a third movable block that moves out from its interior and presses the copper electrode clamped by the first hook and the second hook together.

[0005] Preferably, the second movable block is provided with a second adjusting screw that drives it to move on the fixture body, and the second adjusting screw is threadedly rotated to the fixture body.

[0006] Preferably, a connecting post is provided between the second movable block and the second adjusting screw, and the connecting post is horizontally mounted inside the second movable block. The connecting post and the second movable block are in the same direction of movement. A connecting shaft is provided inside the connecting post to form a kinematic pair with the second movable block. The connecting shaft and the second adjusting screw are coaxially rotatably connected. A locking ring is provided at the bottom end of the connecting shaft to limit its rotation inside the connecting post. The locking ring is located at the bottom outside the connecting post and rotates coaxially with the connecting shaft.

[0007] Preferably, the first movable block is provided with a first adjusting screw that drives the third movable block to translate inside it, and the first adjusting screw crossbar passes through the first movable block. The first movable block is also provided with a through hole for the third movable block to move out from inside it, and the upper and lower ends of the other opening of the through hole are provided with limiting pins to constrain the stroke of the third movable block.

[0008] Preferably, the third movable block is provided with a ball bearing that moves synchronously with it, and the ball bearing is located on the front side of the third movable block, and the third movable block drives the ball bearing to make pressing contact with the top surface of the copper electrode.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When the copper electrode is placed between the first hook and the second hook, and one side of the copper electrode's stepped surface is used as the reference surface, the first hook fixes the reference surface of the copper electrode. Then, the second movable block, together with the second hook, moves to the other side of the copper electrode and fits against it, and together with the first hook, clamps the copper electrode. During the clamping process, the third movable block moves out from inside the first movable block and fits against the top surface of the copper electrode, fixing its position so as to further press the copper electrode clamped by the first hook and the second hook. Thus, through the coordinated cooperation between the first hook, the second hook, and the third movable block, the copper electrode is positioned, corrected, and fixed in three directions. This allows for direct clamping and reuse of coordinates when replacing the same type of copper electrode, eliminating the need for repeated correction operations, reducing labor intensity, shortening the copper electrode replacement time, ensuring the accuracy of repeated positioning, reducing machine tool standby time, and improving equipment utilization.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 In this embodiment of the present invention, a three-way rapid positioning copper electrode clamp for an EDM machine includes a clamp body 2, a first hook 3 disposed on one side of the clamp body 2, a first movable block 4 and a second movable block 7 that move horizontally on the other side of the clamp body 2, and a clamp handle 1 that connects the clamp body 2 to the EDM spindle. The second movable block 7 is provided with a second hook 8 that moves synchronously with it and clamps the copper electrode 6 together with the first hook 3. The first movable block 4 is provided with a third movable block 10 that moves out from its interior and presses the copper electrode 6 clamped by the first hook 3 and the second hook 8. This allows the copper electrode 6 to be placed between the first hook 3 and the second hook 8, with one side of the stepped surface of the copper electrode 6 as the reference surface. The first hook 3 fixes the reference surface of the copper electrode 6, and the second hook 8... The movable block 7, together with the second hook 8, moves to the other side of the copper electrode 6 and fits against it. Together with the first hook 3, it clamps the copper electrode 6. During the clamping process, the third movable block 10 moves out from inside the first movable block 4 and fits against the top surface of the copper electrode 6, fixing its position. This further presses the copper electrode 6, which is clamped by the first hook 3 and the second hook 8, together. Through the coordinated cooperation of the first hook 3, the second hook 8, and the third movable block 10, the copper electrode 6 is positioned, corrected, and fixed in three directions. This allows for direct clamping and reuse of coordinates when replacing the same type of copper electrode 6, eliminating the need for repeated correction operations, reducing labor intensity, shortening copper electrode replacement time, ensuring the accuracy of repeated positioning, reducing machine tool downtime, and improving equipment utilization.

[0019] The second movable block 7 is provided with a second adjusting screw 9 that drives it to move on the clamp body 2, and the second adjusting screw 9 is threadedly rotated to the clamp body 2, so that rotating the second adjusting screw 9 causes the second movable block 7 to slide on the clamp body 2, thereby causing the second hook 8 to move along the X-axis direction relative to the first hook 3, adjusting the distance between it and the first hook 3 so that different types of copper electrodes 6 can be clamped.

[0020] A connecting post 11 is provided between the second movable block 7 and the second adjusting screw 9. The connecting post 11 is horizontally mounted inside the second movable block 7, and the connecting post 11 and the second movable block 7 move in the same direction. A connecting shaft 14 is provided inside the connecting post 11, which forms a kinematic pair with the second movable block 7. The connecting shaft 14 is coaxially rotatably connected to the second adjusting screw 9. A locking ring 15 is provided at the bottom end of the connecting shaft 14 to limit its rotation inside the connecting post 11. The locking ring 15 is located at the bottom outside the connecting post 11. At this location, the locking ring 15 rotates coaxially with the connecting shaft 14, causing the second adjusting screw 9 to rotate threadedly inside the clamp body 2, which in turn causes the connecting shaft 14 to rotate inside the connecting column 11. The second adjusting screw 9 will move along with the connecting column 11, thereby causing the connecting column 11 to move along with the second movable block 7 on the clamp body 2 during the movement. This causes the second hook 8 to move along the X-axis direction relative to the first hook 3, adjusting the distance between it and the first hook 3 so that different types of copper electrodes 6 can be clamped.

[0021] The first movable block 4 is provided with a first adjusting screw 5 that drives the third movable block 10 to move horizontally inside it. The first adjusting screw 5 passes through the first movable block 4. The first movable block 4 is also provided with a through hole 12 for the third movable block 10 to move out from inside it. At the upper and lower ends of the other opening of the through hole 12, there are limiting pins 16 to constrain the stroke of the third movable block 10. Thus, when the first hook 3 and the second hook 8 clamp the copper electrode together, the first movable block 4 moves together with the third movable block 10 to the top surface of the copper electrode. By rotating the first adjusting screw 5, the third movable block 10 is driven to move out from inside the first movable block 4 through the through hole 12, so that the third movable block 10 abuts against the top surface of the copper electrode. Thus, the first hook 3, the second hook 4 and the third movable block 10 form a three-point alignment, thereby performing three-way positioning, correction and fixation of the copper electrode clamped between the first hook 3 and the second hook 8.

[0022] The third movable block 10 is provided with a ball bearing 11 that moves synchronously with it. The ball bearing 11 is located on the front side of the third movable block 10. The third movable block 10 drives the ball bearing 11 to press against the top surface of the copper electrode 6, thereby making the ball bearing 11 press against the copper electrode 6 at a point and reducing friction to avoid damaging the surface of the copper electrode 6.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
