Description

Technical Field

[0001] This utility model relates to the field of wire electrical discharge machining technology, and in particular to a gear rack and pinion guide wheel wire frame structure for wire EDM machine tools. Background Technology

[0002] In the field of wire EDM, the wire frame structure is a core component that ensures stable operation of the molybdenum wire and guarantees cutting accuracy. Currently, most wire EDM machines on the market use traditional slide bars or simple guide rail structures to adjust the position of the small guide wheel and wire stabilizer. This results in low adjustment accuracy and easy loosening after locking, leading to unstable molybdenum wire tension and easy precision deviations in the processed parts.

[0003] Meanwhile, existing wire frame adjustments rely heavily on manual estimation, lacking precise transmission mechanisms. This makes it difficult to achieve fine adjustments to the height of small guide wheels, and the guide wheel plate fixing structure lacks reliability, easily shifting due to vibration after long-term use, affecting processing stability. Furthermore, the traditional guide wheel groove design is unreasonable, making the molybdenum wire prone to falling off or wearing, further reducing processing efficiency and product quality, and failing to meet the processing requirements of high-precision parts.

[0004] Based on this, a gear rack and pinion guide wheel wire frame structure for wire EDM machines is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a gear rack and pinion guide wheel wire frame structure for wire EDM machines in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A gear rack and pinion small guide wheel wire frame structure for a wire EDM machine includes a linear guide rail, a support plate slidably connected to one side of the linear guide rail, a wire frame connected to one side of the support plate, a fixed bracket and small guide wheels connected to the wire frame, a wire stabilizer connected to the fixed bracket, a guide wheel plate slidably connected to one side of the linear guide rail, a guide wheel assembly and a second locking block connected to the guide wheel plate, and a limiting mechanism for fixing the position of the wire frame connected to the support plate.

[0007] Preferably, a slider is slidably connected to the linear guide rail, and the support plate is fixedly connected to the slider.

[0008] Preferably, an adapter bracket is fixedly connected to one side of the bracket plate, and the wire frame is fixedly connected to the adapter bracket.

[0009] Preferably, a second slider is slidably connected to the linear guide rail, and the guide wheel plate is fixedly connected to the second slider.

[0010] Preferably, the limiting mechanism includes a locking block, one end of which is fixedly connected to the support plate, and a screw is connected to the locking block.

[0011] Preferably, a rack is fixedly connected to one side of the linear guide rail, a rotating shaft is connected to the bracket plate through a bearing, a gear is connected to one end of the rotating shaft, a wrench hole is opened at one end of the rotating shaft, and a pressure cap is connected to the bracket plate.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. This application abandons the traditional slide bar adjustment method and uses the precise meshing of gears and racks to achieve fine adjustment of the height of the small guide wheel. The linear guide rail and slider one and slider two further improve the movement stability. The U-shaped locking block one can be tightly abutted against the rack after being locked with screws to avoid loosening after adjustment, effectively solve the problem of unstable molybdenum wire tension, and significantly improve the precision of the processed parts.

[0013] 2. This application allows for flexible adjustment of the relative positions of the small guide wheel and the wire stabilizer via a fixed bracket, ensuring a stable molybdenum wire transport path; the locking block two's fixing effect on the guide wheel plate can prevent displacement caused by long-term vibration, thereby improving processing stability and efficiency.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 This utility model provides a technical solution: A gear rack and pinion small guide wheel wire frame structure for a wire EDM machine includes a linear guide rail 1, a support plate 4 slidably connected to one side of the linear guide rail 1, a wire frame 15 connected to one side of the support plate 4, a fixed bracket 16 and a small guide wheel 18 connected to the wire frame 15, a wire stabilizer 17 connected to the fixed bracket 16, a guide wheel plate 13 slidably connected to one side of the linear guide rail 1, a guide wheel assembly 14 and a locking block 19 connected to the guide wheel plate 13, and a limiting mechanism for fixing the position of the wire frame 15 connected to the support plate 4.

[0018] Specifically, such as Figure 1 As shown, a slider 3 is slidably connected to the linear guide rail 1, and a support plate 4 is fixedly connected to the slider 3. By setting the slider 3, the structural stability of the support plate 4 sliding along the linear guide rail 1 is improved.

[0019] Specifically, such as Figure 1 As shown, a converter bracket 9 is fixedly connected to one side of the bracket plate 4, and the wire frame 15 is fixedly connected to the converter bracket 9. By setting the converter bracket 9, the versatility of the wire frame 15 connection is improved, and the small guide wheel 18 on the wire frame 15 and the wire stabilizer 17 can be accurately connected to the molybdenum wire.

[0020] Specifically, such as Figure 2 As shown, a slider 12 is slidably connected to the linear guide rail 1, and a guide wheel plate 13 is fixedly connected to the slider 12. By setting the slider 12, the stability of the guide wheel plate 13 structure moving along the linear guide rail 1 is improved.

[0021] Specifically, such as Figure 3 As shown, the limiting mechanism includes a locking block 10. One end of the locking block 10 is fixedly connected to the bracket plate 4. A screw 11 is connected to the locking block 10. The locking block 10 has a U-shaped structure. The hole where the screw 11 connects to one end of the locking block 10 is a through hole, while the other end is a threaded hole. By rotating the screw 11, the threaded hole end of the locking block 10 can abut against the rack 2, thus locking the structure of the bracket plate 4.

[0022] Specifically, such as Figure 3 As shown, a rack 2 is fixedly connected to one side of the linear guide rail 1. A rotating shaft 6 is connected to the bracket plate 4 through a bearing. A gear 7 is connected to one end of the rotating shaft 6. A wrench hole 8 is opened at one end of the rotating shaft 6. A pressure cap 5 is connected to the bracket plate 4. The rotating shaft 6 is rotatably connected to the bracket plate 4, and two bearings are provided at the connection to improve the stability of the rotation of the rotating shaft 6. The pressure cap 5 is set on one side of the bearing to limit the bearing. The wrench hole 8 is provided to facilitate the rotation of the rotating shaft 6 and adjust the height of the bracket plate 4.

[0023] In summary, the gear rack and pinion small guide wheel wire frame structure for wire EDM provided in this embodiment requires the molybdenum wire to pass through the wire stabilizer 17 and be introduced onto the small guide wheel 18 and guide wheel assembly 14 during molybdenum wire cutting, so that the molybdenum wire can pass through the cutting area.

[0024] When it is necessary to adjust the position of the small guide wheel 18 and the wire stabilizer 17, the locking block 10 can be released from the state of being clamped on one side of the rack 2 by rotating the screw 11. Then, insert the wrench into the wrench hole 8 and rotate the shaft 6. At this time, the gear 7 connected to one end of the shaft 6 will rotate. Due to the limitation of the rack 2, the height of the bracket plate 4 will be raised or lowered. After the adjustment is completed, the screw 11 can be rotated again to deform one end of the locking block 10. The locking block 10 will abut against the rack 2, thereby stabilizing the vertical height of the bracket plate 4.

[0025] By adjusting the position of the fixed bracket 16 and the small guide wheel 18 connected to the wire frame 15, the stable transportation of molybdenum wire is ensured. The small guide wheel 18 and the rotating wheel at one end of the guide wheel group 14 are provided with V-shaped grooves to facilitate the molybdenum wire to be clamped on the rotating wheel.

[0026] The guide wheel plate 13 can be structurally fixed by locking block 2 19, and screw 11 is also connected to locking block 2 19.

[0027] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
