Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting equipment technology, and in particular to a rotary platform wire cutting machine. Background Technology
[0002] "Jade is a special mineral that ancient people selected and confirmed as having social and precious value through tens of thousands of years of using and choosing stones to make tools." The changing times and the trials of history have not diminished the development trend of jade culture; with the improvement of people's aesthetics and material conditions, jade products are becoming increasingly popular with consumers.
[0003] A wire EDM machine is a specialized machine tool that uses a high-speed rotating diamond wire or molybdenum wire to cut non-conductive materials, and it can be used for jade processing. Understandably, to maintain the stability of the jade during processing, the larger surface of the jade needs to be aligned with the fixed surface of the wire EDM machine's platform, maximizing the contact area between the jade and the fixed surface. This results in a fixed angle between the jade and the wire EDM machine, and the direction of the cutting line used by the wire EDM machine is also fixed. In other words, a single wire EDM machine can only cut jade from a specific fixed angle, significantly limiting its usability. Utility Model Content

[0026] refer to Figures 1-3As shown in the figure, an embodiment of this utility model proposes a rotary platform wire cutting machine for cutting workpieces including but not limited to jade. The rotary platform wire cutting machine includes a frame 10, a cutting assembly 20, and a fixing assembly 30. Both the fixing assembly 30 and the cutting assembly 20 are mounted on the frame 10. The cutting assembly 20 includes a cutting wire 210, a feed wheel 21, a first guide wheel 22, a second guide wheel 23, and a first driving member 211. The cutting wire 210 is wound in a ring around the first guide wheel 22, the second guide wheel 23, and the feed wheel 21. The first driving member 211 is connected to the feed wheel 21 to drive the feed wheel 21 to rotate. The portion of the cutting wire 210 located between the first guide wheel 22 and the second guide wheel 23 is used to cut the workpiece. The fixing assembly 30 includes a first fixing platform 31, a second fixing platform, and a second driving member 34. The first fixing platform 31 is provided with a first fixing surface for fixing the workpiece, and the second fixing platform is provided with a second fixing surface for fixing the workpiece. The first fixing surface and the second fixing surface are perpendicular to each other, and the first fixing surface is parallel to the portion of the cutting line 210 located between the first guide wheel 22 and the second guide wheel 23. The second driving member 34 is connected to the first fixing platform 31 to drive the first fixing platform 31 to rotate around an axis perpendicular to the first fixing surface.
[0027] The aforementioned rotary platform wire EDM machine integrates a first fixed platform 31 and a second fixed platform onto the same machine. The first fixed surface of the first fixed platform 31 and the second fixed surface of the second fixed platform are perpendicularly arranged. When the workpiece is fixed on the first fixed platform 31 with its larger surface facing the first fixed surface, the cutting wire 210 can cut the workpiece in a direction parallel to its larger surface. When the workpiece is fixed on the second fixed platform with its larger surface facing the second fixed surface, the cutting wire 210 can cut the workpiece in a direction perpendicular to its larger surface, thus meeting the processing requirements of different workpiece angles and improving the applicability of the rotary platform wire EDM machine. Furthermore, the rotating arrangement of the first fixed platform 31 allows the cutting wire 210 to perform circular cutting on the workpiece, further enhancing the applicability of the rotary platform wire EDM machine.
[0028] It is understood that the second fixing surface, which is perpendicular to the first fixing surface, can be either parallel to or perpendicular to the cutting line 210. In one embodiment, the first guide wheel 22 and the second guide wheel 23 are arranged vertically at intervals. The portion of the cutting line 210 located between the first guide wheel 22 and the second guide wheel 23 extends vertically. The first fixing surface is vertically arranged, while the second fixing surface is horizontally arranged to improve the stability of the workpiece on the second fixing surface.
[0029] To further improve the applicability of the rotary platform wire EDM machine, the fixing component 30 is movable relative to the cutting component 20 in a direction perpendicular to the first fixing surface. It is understood that the movement of the fixing component 30 relative to the cutting component 20 in a direction perpendicular to the first fixing surface can mean that the fixing component 30 is movably mounted on the frame 10 in a direction perpendicular to the first fixing surface, the cutting component 20 is movably mounted on the frame 10 in a direction perpendicular to the first fixing surface, or both the fixing component 30 and the cutting component 20 are movably mounted on the frame 10 in a direction perpendicular to the first fixing surface. When the workpiece is fixed on the first fixing table 31 or the second fixing table, the movement of the fixing component 30 relative to the cutting component 20 in a direction perpendicular to the second fixing surface can adjust the cutting position of the cutting wire 210 on the workpiece.
[0030] refer to Figure 1 and Figure 2 As shown, the fixing component 30 can also move relative to the cutting component 20 in a horizontal direction parallel to the first fixing surface. When the workpiece is fixed on the first fixing table 31 or the second fixing table, the fixing component 30 can move relative to the cutting component 20 in a horizontal direction parallel to the first fixing surface to adjust the cutting depth of the cutting wire 210 on the workpiece. Furthermore, to reduce the possibility of the cutting wire 210 moving axially along the first guide wheel 22 or the second guide wheel 23 when cutting the workpiece, the entire plane of the cutting wire 210 is parallel to the plane of the first fixing surface. Clearly, the fixing component 30 can move relative to the cutting component 20 in a horizontal direction parallel to the first fixing surface. This can mean that the cutting component 20 is movably mounted on the frame 10 in a horizontal direction parallel to the first fixing surface, the fixing component 30 is movably mounted on the frame 10 in a horizontal direction parallel to the first fixing surface, or both the fixing component 30 and the cutting component 20 are movably mounted on the frame 10 in a horizontal direction parallel to the first fixing surface.
[0031] Taking the fixing component 30 movably disposed on the frame 10 as an example, the fixing component 30 also includes a base 33. The first fixing platform 31 and the second fixing platform are both disposed on the base 33. The base 33 can slide on the frame 10 in a direction perpendicular to the first fixing surface, and can also slide on the frame 10 in a horizontal direction parallel to the first fixing surface.
[0032] To prevent the cutting wire 210 from damaging the second fixing platform, the second fixing platform includes at least two spaced fixing beams 32. The upper surfaces of the fixing beams 32 are at the same height to form a second fixing surface. A clearance gap is formed between adjacent fixing beams 32, through which the cutting wire 210 passes to process the workpiece. The workpiece can be directly bonded to the multiple fixing beams 32 or fixed using a clamp, which will not be described in detail here.
[0033] For example, if the plane containing the cutting line 210 is parallel to the first fixed surface, then the fixing beams 32 are spaced apart in a direction perpendicular to the first fixed surface, and the fixing beams 32 extend in a horizontal direction parallel to the first fixed surface. To prevent the cutting line 210 from damaging the base 33, the base 33 is configured as a rectangular frame structure. The two ends of the fixing beams 32 are fixed to the opposite sides of the frame of the base 33 in a horizontal direction parallel to the first fixed surface. The first guide wheel 22 and the second guide wheel 23 are respectively mounted on the frame 10 through the first support arm 25 and the second support arm 29, wherein the second support arm 29 is inserted into the base 33 along the extension direction of the fixing beam 32.
[0034] refer to Figure 1 As shown, the first fixed platform 31 is disc-shaped to prevent it from scratching the operator when rotating. Similarly, the workpiece is directly bonded to the first fixed platform 31, or the workpiece is fixed to the fixed platform using a clamp. Based on the clamp, the first fixed platform 31 has multiple mounting holes to fix the clamp to the first fixed platform 31 using fasteners that pass through the mounting holes.
[0035] To enable the automatic movement of the base 33, the rotary platform wire cutting machine also includes a drive assembly (not shown in the figure). The drive assembly includes a third drive member, a fourth drive member, and a sliding seat 11. The sliding seat 11 is slidably mounted on the frame 10 in a horizontal direction parallel to the first fixed surface. The third drive member is connected to the sliding seat 11 to drive the sliding seat 11 to move. The base 33 is slidably mounted on the sliding seat 11 in a horizontal direction perpendicular to the first fixed surface. The fourth drive member is connected to the base 33 to drive the base 33 to move.
[0036] More specifically, to improve the stability of the fixed component 30 on the base 33, the rotary platform wire EDM machine also includes a lead screw drive assembly. The third and fourth drive components are each connected to the sliding seat 11 and the base 33 via the lead screw drive assembly to achieve self-locking. In this case, both the third and fourth drive components are motors. The lead screw drive assembly is prior art and will not be described in detail here.
[0037] Of course, the driving component can also be connected to the cutting component 20, and the movement of the fixed component 30 relative to the cutting component 20 can be achieved by driving the cutting component 20, which will not be explained further here.
[0038] Continue to refer to Figure 1As shown, to further improve the applicability of the rotary platform wire EDM machine and enable it to cut workpieces of different sizes located on the first fixed table 31, the height of the first guide wheel 22 on the frame 10 is adjustable. It is understood that the first guide wheel 22 should be as close as possible to the second guide wheel 23 while avoiding the workpiece, in order to shorten the length of the cutting line 210 located between the first guide wheel 22 and the second guide wheel 23, thereby improving the stability of the cutting line 210 portion corresponding to the workpiece being cut.
[0039] Specifically, the frame 10 is provided with a first guide rail 12 extending in the vertical direction, and a slider is provided on the first support arm 25 connected to the first guide wheel 22. The slider is slidably disposed on the first guide rail 12. By adjusting the height of the first support arm 25 on the frame 10, the height of the first guide wheel 22 can be adjusted.
[0040] In order to lock the first support arm 25 and the frame 10 and maintain the stability of the first support arm 25 on the frame 10, the cutting assembly 20 also includes a locking member. The locking member passes through the slider in a horizontal direction parallel to the first fixed surface and is threadedly connected to the slider. By screwing the locking member, it can be pressed against the guide rail, thereby fixing the first support arm 25 on the frame 10.
[0041] To keep the cutting wire 210 taut, the cutting assembly 20 also includes a tensioning wheel 24, which is vertically mounted on the frame 10. The cutting wire 210 passes over the tensioning wheel 24. The cutting assembly 20 also includes a counterweight 28, a reversing wheel 26, and a connecting line 27. The reversing wheel 26 is rotatably mounted on the frame 10 and located above the tensioning wheel 24. One end of the connecting line 27 is connected to the tensioning wheel 24, and the other end passes over the reversing wheel 26 and connects to the counterweight 28. Under the action of the counterweight 28, the tensioning wheel 24 maintains an upward tendency, thus keeping the cutting wire 210 taut throughout the lifting and lowering process of the first guide wheel 22.
[0042] Specifically, in order to improve the moving stability of the tension wheel 24 and the counterweight 28, the frame 10 is provided with a second guide rail 13 and a third guide rail 14. Both the second guide rail 13 and the third guide rail 14 extend in the vertical direction. The tension wheel 24 is slidably mounted on the second guide rail 13 through the mounting base, and the counterweight 28 is slidably mounted on the third guide rail 14.
[0043] refer to Figure 3 As shown, the rotary platform wire EDM machine also includes a protective cover 40, which covers the fixing assembly 30 and the cutting assembly 20 to prevent debris from splashing onto the operator during the cutting process. Specifically, the protective cover 40 includes a cover body 41 and a door 42. The cover body 41 has an opening on at least one side, and the door 42 is movably mounted on the cover body 41 to open or close the opening, thereby facilitating the loading and unloading of workpieces.
[0044] For ease of operation, the rotary table wire cutting machine also includes an operation panel 50 connected to the cutting assembly 20, the fixing assembly 30, and the drive assembly. The operation panel 50 is mounted on the protective cover 40, and the operator can control the cutting assembly 20, the fixing assembly 30, and the drive assembly by manipulating the operation panel 50.
[0045] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
