Description
Technical Field
[0001] This utility model relates to the technical field of mold parts processing, specifically to a copper electrode clamping mechanism. Background Technology
[0002] In the mold manufacturing field, spark electrical discharge machining (EDM) is a crucial process for handling complex cavities, ribs, and narrow, deep structures, playing an irreplaceable role, especially for areas that are difficult to directly form using machining centers. These intricate structures typically require extremely high machining accuracy, thus placing higher demands on the positioning accuracy and clamping stability of the electrode. In traditional EDM processes, the electrode needs to be fixed to the machine head using a fixture. However, existing fixture methods for fixing the electrode are relatively limited, requiring replacement with different fixtures. Therefore, further improvements are needed. Utility Model Content
[0003] This utility model proposes a copper electrode clamping mechanism. A sliding engagement is formed between the connector's groove and a first slider and a second slider. This is complemented by a first fastener that can move axially up and down on the first slider, and two second sliders extending downwards from the first slider. At least two clamping methods are provided: one is that the first slider and the first fastener cooperate with at least one second slider to position and lock the copper electrode; the other is that the copper electrode is directly clamped between the two second sliders. This design breaks through the limitation of traditional clamping methods, allowing for the selection of an appropriate clamping method based on actual processing requirements.
[0004] A copper electrode clamping mechanism designed for this purpose includes a main clamping device. The main clamping device is provided with a connector, a first slider and a second slider. The connector is provided with a sliding groove. The first slider and the second slider are slidably engaged with the sliding groove. The first slider is provided with a first fastener for locking the copper electrode. The first fastener moves axially up and down on the first slider. The second slider is provided in two parts. One end of the second slider extends downward below the first slider, and the two second sliders are used to cooperate with the first slider and the first fastener for positioning and locking copper electrode. Alternatively, the copper electrode can be clamped between the two second sliders.
[0005] The second slider is detachably mounted on the connector, and at least one end of the slide groove is an open end. The connector is installed or removed from the open end onto the slide groove.
[0006] The connector has an elongated groove, and the second slider has a fixing hole and a first fixing member. The first fixing member is inserted into the elongated groove and the fixing hole. By locking or releasing the first fixing member, the second slider can be locked or released on the connector.
[0007] The long slot is fitted with a third fastener for locking the copper electrode, at least after the second slider is removed.
[0008] The second slider has a first positioning reference part and a second positioning reference part at its two ends respectively. By adjusting the installation direction of the second slider, the copper electrode can be clamped on the first positioning reference part or the second positioning reference part. The first positioning reference part is provided with an upper positioning platform and a lower positioning slot arranged at intervals, and the copper electrode is selectively positioned on the upper positioning platform or the lower positioning slot.
[0009] The second slider is provided with an inclined surface for balancing and placing the positioning copper electrode, and the inclined surface is set on the upper positioning platform.
[0010] The second slider is provided with a connecting hole. When the two second sliders clamp the copper electrode, a second fixing member is inserted between the two connecting holes to lock the two second sliders.
[0011] The connector is equipped with a positioning post, which is detachably installed on the connector to allow for the replacement of positioning posts of different lengths.
[0012] The connector is provided with a positioning groove, one end of the positioning post is installed on the positioning groove, and a fastening hole and a third fixing member are provided between the connector and the positioning post. The third fixing member is inserted into the two fastening holes. By locking or releasing the third fixing member, the positioning post can be locked or released on the connector.
[0013] The positioning post has a first chamfer structure on its periphery.
[0014] The slide is a dovetail groove, and the first slider and the second slider are wedge-shaped fits with the slide.
[0015] The copper electrode clamping mechanism also includes a secondary device, which has a fixed base and two third sliders. The two third sliders are slidably disposed on the fixed base and are used to position the copper electrode between them. The mounting base is provided with a slot for positioning and installing the connecting column. The connecting column and the copper electrode are respectively positioned on the mounting base and fixedly connected by adhesive.
[0016] The beneficial technical effects of this utility model are as follows: The connector's groove forms a sliding engagement with the first and second sliders. Combined with a first fastener that can move axially up and down on the first slider, and two second sliders extending downwards from the first slider, at least two clamping methods are provided: one is that the first slider and the first fastener engage with at least one second slider to position and lock the copper electrode; the other is that the copper electrode is directly clamped between the two second sliders. This design breaks through the limitation of traditional fixtures having only one clamping method, allowing for the selection of an appropriate clamping method based on actual processing requirements.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.
[0029] See Figures 1-10 A copper electrode clamping mechanism includes a main clamping device 1. The main clamping device 1 is provided with a connector 2, a first slider 3 and a second slider 5. The connector 2 is provided with a sliding groove 201. The first slider 3 and the second slider 5 are slidably engaged with the sliding groove 201. The first slider 3 is provided with a first fastener 4 for locking the copper electrode 6. The first fastener 4 moves axially up and down on the first slider 3. The second slider 5 is provided in two parts. One end of the second slider 5 extends downward below the first slider 3. The two second sliders 5 are used to cooperate with the first slider 3 and the first fastener 4 to position and lock the copper electrode 6. Alternatively, the copper electrode 6 can be clamped between the two second sliders 5.
[0030] The first fastener, number 4, is a screw.
[0031] The connector 2 forms a sliding engagement with the first slider 3 and the second slider 5 through the groove 201. Combined with the first fastener 4, which is axially movable on the first slider 3, and two second sliders 5 extending downwards from the first slider 3, at least two clamping methods are provided: one is that the first slider 3 and the first fastener 4 cooperate to position and lock the copper electrode 6 with at least one second slider 5; the other is that the copper electrode 6 is directly clamped between the two second sliders 5. This design breaks through the limitation of the single clamping method in traditional fixtures, allowing the selection of an appropriate clamping method according to actual processing requirements.
[0032] The first clamping method is as follows: Figure 4 , Figure 5 As shown: The first slider 3 can be slidably disposed between the two second sliders 5. When the first fastener 4 of the first slider 3 locks the copper electrode 6, one end face of the copper electrode 6 first abuts against the second slider 5. Using the second slider 5 as the positioning reference surface, the first fastener 4 moves downward to lock the copper electrode 6. The copper electrode 6 is positioned between the two second sliders 5, or positioned on one of the sliders 5.
[0033] The second clamping method is as follows: Figure 6 , Figure 7As shown: Two second sliders 5 are fixed to the connecting member 2. A copper electrode 6 is clamped onto the first positioning reference part 502 between the two second sliders 5. The first positioning reference part 502 is provided with an upper positioning platform 5021 and a lower positioning slot 5022. The two ends of the copper electrode 6 are supported on the upper positioning platform 5021. The two second sliders 5 are fixedly connected by a transverse second fixing member 8. One of the second sliders 5 is fixed to the connecting member 2 by a first fixing member 10. The other second slider 5 can move on the connecting member 2 when the second fixing member 8 is not inserted or locked.
[0034] The first and second clamping methods facilitate the rapid positioning and calibration of the copper electrode 6.
[0035] The second slider 5 is detachably mounted on the connector 2. At least one end of the slide groove 201 is an open end, and the connector 2 is installed or removed from the open end onto the slide groove 201.
[0036] The second slider 5 is detachably mounted on the connector 2, and at least one end of the slide groove 201 is an open end, allowing the connector 2 to quickly install or remove the second slider 5 from the open end. This design makes the installation and removal of the second slider 5 more convenient, and the second slider 5 can be installed or removed from the connector 2 according to processing requirements.
[0037] The connector 2 is provided with a long groove 202, and the second slider 5 is provided with a fixing hole 501 and a first fixing member 10. The first fixing member 10 is inserted into the long groove 202 and the fixing hole 501. By locking or releasing the first fixing member 10, the second slider 5 can be locked or released on the connector 2.
[0038] The first fastener is a screw.
[0039] The elongated groove 202 structure allows the second slider 5 to be flexibly adjusted along the direction of the elongated groove 202, achieving stepless adjustment and accurately adapting to copper electrodes 6 of different sizes without the need to replace special clamps, thus improving the versatility of the mechanism. The locking method of the first fixing member 10 is simple and reliable, and can quickly fix the position of the second slider 5.
[0040] The long slot 202 is equipped with a third fastener 7 for locking the copper electrode 6 at least after the second slider 5 is disassembled. The long slot 202 can be equipped with the third fastener 7 to lock the copper electrode 6 after the second slider 5 is disassembled, thus adding a simple clamping method to the copper electrode 6 clamping mechanism.
[0041] The second slider 5 has a first positioning reference part 502 and a second positioning reference part 503 at its two ends, respectively. By adjusting the installation direction of the second slider 5, the copper electrode 6 can be clamped on the first positioning reference part 502 or the second positioning reference part 503. The dual-reference design eliminates the need to replace the second slider 5. Different positioning requirements of the copper electrode 6 can be met simply by adjusting the installation direction, reducing the need for dedicated positioning parts and lowering the cost of use.
[0042] The first positioning reference part 502 is provided with two positioning steps spaced apart, and the second positioning reference part 503 is provided with a locking groove.
[0043] The first positioning reference part 502 is provided with an upper positioning platform 5021 and a lower positioning slot 5022 arranged at intervals. The copper electrode 6 is selectively positioned on the upper positioning platform 5021 or the lower positioning slot 5022.
[0044] The second slider 5 is provided with an inclined surface 505 for balancing and placing the positioning copper electrode 6, and the inclined surface 505 is set on the upper positioning platform 5021.
[0045] The two second sliders 5 are set in parallel, and the two inclined planes 505 are set symmetrically. The reference surfaces on both sides of the copper electrode 6 are placed on the inclined planes 505 of the two second sliders 5, so the copper electrode 6 is relatively flat.
[0046] The first and second clamping methods for standard copper electrodes make it easy to lay the copper electrode flat.
[0047] The third clamping method is as follows: Figure 8 , Figure 9 As shown: one of the second sliders 5 moves to the end of the connector 2 and is fixed to the end of the connector 2. The other second slider 5 can move on the connector 2. When the copper electrode 6 is clamped, one side of the copper electrode 6 is positioned on the fixed second slider 5. Then the movable second slider 5 abuts against the copper electrode 6. After the two second sliders 5 clamp the copper electrode 6, the two second sliders 5 are locked by the transverse second fixing member 8. The copper electrode 6 is clamped in the first positioning reference part 502 between the two second sliders 5, and the lower positioning slot 5022 of the first positioning reference part 502 abuts against the copper electrode 6.
[0048] The fourth clamping method is as follows: Figure 10 , Figure 11 As shown: After disassembling the two second sliders 5, the two second sliders 5 are installed in opposite directions on the connector 2. One of the second sliders 5 is moved to the end of the connector 2 and fixed to the end of the connector 2 (the second fixing part on it is not shown in the figure). The copper electrode 6 is clamped on the second positioning reference part 503 between the two second sliders 5.
[0049] The third and fourth clamping methods, by moving one of the second sliders 5 to the end, can avoid interference between the connector 2 and the mold when machining to the edge of the mold or a relatively deep recessed machining position. When machining a relatively deep recessed machining position, a longer copper electrode 6 can be selected.
[0050] The fifth clamping method is as follows Figure 12 , Figure 13As shown: After disassembling the two second sliders 5, if the bottom surface of the first slider 3 is designed to be flush with the bottom of the connector 2, it is not necessary to disassemble the first slider 3. Just move or remove the first fastener 4 on the first slider 3, and then install the third fastener 7 on each long slot 202. Use the two third fasteners 7 to lock the copper electrode 6. The bottom surface of the connector 2 can abut against the upper part of the copper electrode 6 as a positioning reference.
[0051] The second slider 5 is provided with a connecting hole 504. When the two second sliders 5 clamp the copper electrode 6, the second fixing member 8 is inserted between the two connecting holes 504 to lock the two second sliders 5.
[0052] The second fastener 8 is a screw.
[0053] The connector 2 is provided with a positioning post 9, which is detachably installed on the connector 2 so that positioning posts of different lengths can be replaced on the connector 2.
[0054] The positioning post 9 on the connector 2 is detachable and can be flexibly replaced with positioning posts 9 of different lengths according to the installation height and processing position of the copper electrode 6.
[0055] The connector 2 is provided with a positioning groove 203. One end of the positioning post 9 is installed on the positioning groove 203. There is a fastening hole 11 and a third fixing member 12 between the connector 2 and the positioning post 9. The third fixing member 12 is inserted into two fastening holes 11. By locking or releasing the third fixing member 12, the positioning post 9 can be locked or released on the connector 2.
[0056] The positioning post 9 is provided with a square shaft to facilitate the rotation of the positioning post 9.
[0057] The third fastener 12 is a screw.
[0058] The slide groove 201 is a dovetail groove, and the first slider 3 and the second slider 5 are wedge-shaped fits with the slide groove 201.
[0059] The slide groove 201 is designed as a dovetail groove, and both the first slider 3 and the second slider 5 are wedge-shaped fits with the slide groove 201. This wedge-shaped fit structure increases the contact area between the slider and the slide groove 201, resulting in more even force distribution and enhancing the connection reliability of the slider within the slide groove 201, preventing loosening or detachment during processing. The dovetail groove structure also ensures smoother slider movement during adjustment, preventing deviation and ensuring that the first slider 3 and the second slider 5 can only move laterally back and forth during adjustment.
[0060] See Figure 11 The copper electrode clamping mechanism further includes a secondary device 13, on which a fixed seat 14 is provided, and two third sliders 15 are provided on the fixed seat 14. The two third sliders 15 are slidably disposed on the fixed seat 14, and the copper electrode 6 is positioned between the two third sliders 15. The fixing base 14 is provided with a slot 1401 for positioning and installing the connecting column 16. The connecting column 16 and the copper electrode 6 are respectively positioned on the fixing base 14 and fixedly connected by adhesive.
[0061] The sixth clamping method is as follows Figure 14 , Figure 15 As shown: Two sliding third sliders 15 are provided on the fixing base 14 of the auxiliary device 13. By adjusting the distance between the third sliders 15, copper electrodes 6 of different widths can be positioned, providing strong adaptability and flexible operation. The slot 1401 of the fixing base 14 can accurately position and install the connecting post 16. After the connecting post 16 and the copper electrode 6 are positioned, they are fixed together with glue. This fixes the copper electrode 6 onto the connecting post 16, with the fixing base 14 serving as the positioning reference for the connecting post 16 and the copper electrode 6. The auxiliary device 13 adds an independent clamping method to the copper electrode 6 clamping mechanism. The auxiliary device 13 can be used independently.
[0062] The chuck of the machining mechanism is equipped with a locking screw. The connecting post 16 or the positioning post 9 of the main clamping device 1 is inserted into the chuck 17. By turning the locking screw, the locking screw abuts against the positioning post 9 or the connecting post 16 to fix the connecting post 16 or the main clamping device 1 on the chuck 17 of the machining mechanism.
[0063] The positioning post 9 has a first chamfer structure 901 around its periphery, and the connecting post 16 has a second chamfer structure 1601 around its periphery. The chamfer structure is easy to lock, and the locking screw (retracting screw) is abutted (pressed) against the chamfer position on the positioning post 9 or the connecting post 16.
[0064] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
