Description

Technical Field

[0001] This application relates to the field of single-wire cutting machine technology, and more particularly to a new type of multi-wire cutting machine's lead-wire guide wheel mechanism. Background Technology

[0002] A wire EDM machine mainly consists of three parts: the machine tool, the CNC system, and the high-frequency power supply. The CNC system comprises a microcontroller, a keyboard, and a frequency conversion detection system, and has key functions such as gap compensation, linear interpolation, circular interpolation, and automatic wire breakage handling. It can cut materials such as high-strength, high-toughness, high-hardness, high-brittleness, and magnetic materials, as well as precision, small, and complex-shaped parts. Wire EDM technology and wire EDM machine tools are being widely used in various industries.

[0003] When using an in-line cutting machine, the lead wire guide wheel overlaps and guides the cutting wire. However, ordinary lead wire guide wheels require a separate tensioning mechanism. In addition, ordinary tensioning mechanisms usually use telescopic rods for adjustment. When the telescopic rod is damaged, the tensioning mechanism will not work. Therefore, we propose a new type of lead wire guide wheel mechanism for multi-wire cutting machines. Utility Model Content

[0004] This application provides a novel lead-wire guide wheel mechanism for a multi-wire cutting machine to solve the problems mentioned above.

[0005] This application provides a novel wire guide wheel mechanism for a multi-wire cutting machine, comprising:

[0006] A first connecting plate and a second connecting plate are fixedly connected at their four corners by connecting rods. A first lead wire guide wheel is rotatably connected to the lower left and right sides of the first and second connecting plates. A rectangular opening is opened on the upper left and right sides of the first and second connecting plates. A connecting block is connected to the inner limit of the rectangular opening and can move up and down. A second lead wire guide wheel is rotatably connected to the middle of the front and rear connecting blocks. The front and rear sides of the rotating shaft of the second lead wire guide wheel are sleeved with a limit frame through bearings. A connecting plate is fixedly connected between the limit frames. A limit shaft is fixedly connected to the middle of the lower end of the connecting plate. A triangular block is fixedly connected to the lower end of the limit shaft. A displacement block is movably provided on the lower inclined surface of the triangular block. The displacement block moves left and right, driving the triangular block to move up and down.

[0007] Preferably, the upper end face of the displacement block is an inclined surface, the lower end of the displacement block is fixedly connected to the upper end of the transmission plate of the lead screw mechanism, and the lead screw mechanism is fixedly connected to the front end face of the second connecting plate.

[0008] Preferably, a limiting plate is movably sleeved on the lower outer side of the limiting shaft, and the rear end of the limiting plate is fixedly connected to the front end face of the second connecting plate through a fixing plate.

[0009] Preferably, a spring is sleeved on the outer side of the limiting shaft between the upper end of the limiting plate and the triangular block.

[0010] Preferably, the inner left and right sides of the rectangular opening are fixedly connected to limit slide rails, and the connecting block is slidably sleeved on the limit slide rails.

[0011] Preferably, the lower inclined surface of the triangular block and the upper inclined surface of the displacement block are on the same plane.

[0012] Preferably, the second lead guide wheel and the first lead guide wheel are arranged in a rectangular array.

[0013] Preferably, fixing holes are provided at the four corners of the first connecting plate and the second connecting plate.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art:

[0015] The structure provided in this application embodiment overlaps the cutting wire on the wire storage wheel with the outside of the symmetrical second lead wire guide wheel and the first lead wire guide wheel. When it is necessary to adjust the tightness of the overlapped cutting wire, the screw mechanism is activated to drive the displacement block to move to the left, thereby lifting the triangular block. This drives the connecting plate, the limit frame, and the second lead wire guide wheel to move upward through the limit shaft, thereby causing the overlapped cutting wire to expand outward and tighten the cutting wire.

[0016] Furthermore, through the transmission method of the lead screw mechanism, even if the transmission motor of the lead screw mechanism is damaged, the displacement block will not be displaced, thereby greatly increasing the positioning stability of the entire mechanism.

[0025] Various embodiments of this application may exist in the form of a range. It should be understood that the description in the form of a range is merely for convenience and brevity and should not be construed as a rigid limitation on the scope of this application. Therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values ​​within that range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges, such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range.

In this application, "and / or" describes the relationship between related objects, indicating that three relationships may exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. A and B can be singular or plural. In this application, "at least one" means one or more, and "more than one" means two or more. "At least one," "at least one of the following," or similar expressions refer to any combination of these items, including any combination of a single item or a plural item. For example, "at least one of a, b, or c", or "at least one of a, b, and c", can both mean: a, b, c, ab, i.e., a and b, ac, bc, or abc, where a, b, and c can be a single or multiple.

[0027] like Figures 1 to 4 As shown, this application provides a novel wire guide wheel mechanism for a multi-wire cutting machine, comprising:

[0028] A first connecting plate 1 and a second connecting plate 2 are fixedly connected at their four corners by connecting rods 3. A first lead wire guide wheel 5 is rotatably connected to the lower left and right sides of the first connecting plate 1 and the second connecting plate 2. A rectangular opening 6 is opened on the upper left and right sides of the first connecting plate 1 and the second connecting plate 2. A connecting block 7 is connected to the inside of the rectangular opening 6 and can be moved up and down. A second lead wire guide wheel 8 is rotatably connected to the middle of the front and rear connecting blocks 7. The front and rear sides of the rotating shaft of the second lead wire guide wheel 8 are sleeved with a limit frame 9 through bearings. A connecting plate 10 is fixedly connected between the limit frames 9. A limit shaft 11 is fixedly connected to the middle of the lower end of the connecting plate 10. A triangular block 12 is fixedly connected to the lower end of the limit shaft 11. A displacement block 16 is movably provided on the lower inclined surface of the triangular block 12. The displacement block 16 moves left and right, driving the triangular block 12 to move up and down.

[0029] like Figure 4 As shown: the upper end face of the displacement block 16 is an inclined surface, the lower end of the displacement block 16 is fixedly connected to the upper end of the transmission plate of the lead screw mechanism 15, and the lead screw mechanism 15 is fixedly connected to the front end face of the second connecting plate 2.

[0030] Specifically: the lead screw mechanism 15 adopts a lead screw that is already available on the market, and all of them are existing technologies.

[0031] like Figure 2 and Figure 4 As shown: the lower outer side of the limiting shaft 11 is movably sleeved with a limiting plate 17, and the rear end of the limiting plate 17 is fixedly connected to the front end face of the second connecting plate 2 through a fixing plate.

[0032] Specifically, the limiting plate 17 can stabilize the vertical displacement of the limiting shaft 11.

[0033] like Figure 4 As shown: A spring 14 is sleeved on the outer side of the limiting shaft 11 between the limiting plate 17 and the upper end of the triangular block 12.

[0034] Specifically: Spring 14 is always in a compressed state.

[0035] like Figure 3 As shown: the inner left and right sides of the rectangular opening 6 are fixedly connected to the limiting slide rails 13, and the connecting block 7 is slidably sleeved on the limiting slide rails 13.

[0036] Specifically: the limiting slide rail 13 can make the vertical displacement of the connecting block 7 more stable.

[0037] like Figure 4 As shown: the lower inclined surface of the triangular block 12 and the upper inclined surface of the displacement block 16 are on the same plane.

[0038] Specifically: when displacement block 16 moves left or right, and under the action of spring 14, triangular block 12 moves up or down.

[0039] like Figure 2 As shown: the second lead guide wheel 8 and the first lead guide wheel 5 are arranged in a rectangular array.

[0040] Specifically: the second lead guide wheel 8 and the first lead guide wheel 5 adopt existing lead guide wheels on the market.

[0041] like Figure 1 As shown: Fixing holes 4 are opened at the four corners of the first connecting plate 1 and the second connecting plate 2.

[0042] Specifically: the fixing hole 4 is fixedly connected to the external equipment by bolts.

[0043] Principle: When the equipment is in use, the first connecting plate 1 and the second connecting plate 2 are fixedly connected to the external fixed equipment with bolts. Then, the cutting wire on the wire storage wheel is overlapped on the outside of the symmetrical second lead wire guide wheel 8 and the first lead wire guide wheel 5. When it is necessary to adjust the tightness of the overlapped cutting wire, the screw mechanism 15 is activated, which drives the displacement block 16 to move to the left and lifts the triangular block 12. This drives the connecting plate 10, the limit frame 9 and the second lead wire guide wheel 8 to move upward through the limit shaft 11, thereby causing the overlapped cutting wire to expand outward and tighten the cutting wire.

[0044] Furthermore, through the transmission method of the lead screw mechanism 15, even if the transmission motor of the lead screw mechanism 15 is damaged, the displacement block 16 will not be displaced, thereby greatly increasing the stability of the entire mechanism's positioning.

[0045] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. 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 this application. Therefore, this application 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 claimed in this application.
