Description

Technical Field

[0001] This utility model relates to the field of cutting mechanism technology, specifically a slow wire EDM positioning cutting mechanism. Background Technology

[0002] In many high-end manufacturing fields such as mold making, precision machining, and electronic component production, wire EDM technology has become a key process due to its superior ability to achieve high-precision and complex shape processing.

[0003] Based on the above, the inventors have discovered the following problems: When performing slow wire EDM, a positioning mechanism is required to fix the workpiece. However, existing positioning mechanisms often use traditional mechanical clamps, such as vise clamps or pressure plate clamps, when holding the workpiece. Due to the lack of automated repositioning function, workers have to manually intervene, interrupt the processing flow, loosen the clamps, carefully remove the workpiece, readjust the workpiece orientation based on experience and visual judgment, and then re-clamp and fix it. This process is not only time-consuming and labor-intensive, but also greatly reduces production efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a slow wire EDM positioning and cutting mechanism in order to achieve a more practical value. Utility Model Content

[0011] Furthermore, a movable groove is formed on the upper end face of the fixed base between the pair of sliding grooves, and a bidirectional lead screw is rotatably connected inside the movable groove.

[0013] Furthermore, both ends of the bidirectional lead screw are threaded with sliders, and the upper ends of the sliders are respectively connected to the bottom ends of a pair of movable frames.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by connecting the slider to the bottom end of the moving frame, the moving frame can be moved relative to the bidirectional lead screw when it rotates, thereby clamping and fixing the workpiece.

[0015] Furthermore, a second servo motor is fixedly installed on one side of the fixed base, and the output end of the second servo motor is connected to a bidirectional lead screw drive.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by installing the first bevel gear, its rotation can drive the roller to rotate.

[0019] Furthermore, the movable frame is internally rotatably connected to a rotating shaft, and a second bevel gear is fitted on each rotating shaft, with the second bevel gear meshing with the first bevel gear.

[0020] The beneficial effect of adopting the above-mentioned further solution is that by meshing the second bevel gear with the first bevel gear, the rotating shaft can drive the roller to rotate, thereby moving the workpiece.

[0031] Please see Figure 1 - Figure 5This utility model provides a technical solution: a slow wire EDM positioning and cutting mechanism, including a main body 100 and a positioning mechanism 200. The main body 100 includes a housing 1001. A first linear motor 1002 is installed on one side of the upper end of the housing 1001.

[0032] 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.

[0033] Please see Figure 1 - Figure 5A first servo motor 2011 is fixedly installed at the top of the power box 2001. The output end of the first servo motor 2011 is connected to the fixed base 2002.

A second servo motor 2010 is installed, which drives the bidirectional lead screw 2004 to rotate during operation.

[0034] 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.

[0035] Please see Figure 1 - Figure 5 The bottom ends of several rollers 2008 extend through the mounting base 2007 into the interior of the movable frame 2006, and each roller is fitted with a first bevel gear 2012. A rotating shaft 2013 is rotatably connected inside the movable frame 2006, and a second bevel gear 2014 is fitted on the rotating shaft 2013. The second bevel gear 2014 meshes with the first bevel gear 2012. A third servo motor 2009 is fixedly installed at one end of the movable frame 2006. The output end of the third servo motor 2009 is connected to the rotating shaft 2013 for transmission. By installing the first bevel gear 2012, its rotation can drive the rollers 2008 to rotate. By meshing the second bevel gear 2014 with the first bevel gear 2012, the rotation of the rotating shaft 2013 can drive the rollers 2008 to rotate, thus moving the workpiece. By installing the third servo motor 2009, its operation can drive the rotating shaft 2013 to rotate.

[0036] Specifically, the working principle of this slow wire EDM positioning and cutting mechanism is as follows: During use, the workpiece to be processed is placed on the upper end of the fixed base 2002. Then, the second servo motor 2010 starts, driving the bidirectional lead screw 2004 to rotate within the moving groove 2003. Since the sliders threaded at both ends of the bidirectional lead screw 2004 are respectively connected to the bottom ends of a pair of moving frames 2006, the sliders drive the moving frames 2006 to move relative to each other along the sliding grooves 2005 on both sides of the fixed base 2002. Several rollers 2008 installed in the mounting seats 2007 on the opposite side of the moving frames 2006 gradually approach the workpiece until they tightly clamp both sides of the workpiece. The telescopic rod 1005 at the moving end of the first linear motor 1002 extends and retracts as needed, adjusting the front-to-back position of the power box 2001 on the upper surface of the housing 1001. Simultaneously, the slow wire EDM machine body 1004 at the moving end of the second linear motor 1003 moves left and right, with both working in tandem. The wire cutting machine body 1004 is positioned to the workpiece to be cut. The wire cutting machine body 1004 is started to process the workpiece. When one end of the workpiece is cut and the other end needs to be processed, the first servo motor 2011 is started, driving the fixed base 2002 to rotate and precisely adjust the workpiece direction. There is no need for manual disassembly and reassembly of the workpiece, avoiding positioning errors and time losses caused by manual operation, and ensuring processing accuracy and continuity. At the same time, the third servo motor 2009 is started, driving the rotating shaft 2013 to rotate. Through the meshing of the second bevel gear 2014 and the first bevel gear 2012, the roller 2008 is rotated. The roller 2008 can slowly move the workpiece so that the unprocessed end of the workpiece extends out of the fixed base 2002, which makes it convenient for the wire cutting machine body 1004 to cut the new part, further improving processing flexibility and efficiency.
