Technical Field

[0001] This application belongs to the field of wire EDM technology, and particularly relates to a wire EDM auxiliary device and a wire EDM equipment. Background Technology

[0002] Wire EDM equipment is mainly used for processing irregularly shaped samples. In related technologies, relying on the operator to visually judge the angle of the sample placement and select the infeed position cannot ensure that the angle of the sample placement is perpendicular to the infeed direction of the molybdenum wire. This causes the molybdenum wire to deviate from the sample during the cutting process and scratch the sample, which not only affects the processing accuracy of the sample, but also wastes the sample material.

[0019] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0020] The following is for reference. Figures 1-4 This application describes a wire cutting auxiliary device and a wire cutting apparatus according to embodiments thereof.

[0021] Please see Figures 1 to 4 This application provides a wire cutting auxiliary device 5 for installation on a wire cutting equipment 100. The wire cutting equipment 100 includes a cutting line 3 and two material carriers 4 spaced apart on both sides of the cutting line 3. The wire cutting auxiliary device 5 includes two positioning components 51, two right-angle clamps, a ruler 53, and a laser plumb line instrument 54.

[0022] Two positioning members 51 are respectively used to be installed on two material carriers 4. The positioning members 51 are provided with connecting parts 512, which are detachable from the material carriers 4.

[0023] The two positioning components 51 form the mounting base of the entire auxiliary device, used to stably assemble the device onto the loading platform 4. The positioning components 51 can be made of metal, possessing good structural strength to ensure positioning stability. The connecting portion 512 serves as the connection structure between the positioning components 51 and the loading platform 4, and can include any of the following embodiments: In some examples, the connecting part 512 can be an elastic buckle set at the bottom of the positioning member 51, and the loading platform 4 is provided with a corresponding slot. The buckle can be elastically inserted into the slot to achieve a detachable connection. During installation, the positioning member 51 can be pressed on the loading platform 4 to complete the fixation. During disassembly, the buckle release end can be turned to separate it.

[0024] In other examples, the connecting part 512 is a waist-shaped hole opened on the positioning member 51, which is matched with the threaded hole preset on the loading platform 4. The positioning member 51 can be detachably fixed by passing a hand-tightened bolt through the waist-shaped hole and screwing it into the threaded hole. The setting of the waist-shaped hole allows the positioning member 51 to be adjusted within a small range on the loading platform 4.

[0025] In some other examples, when the loading platform 4 is made of iron, the connecting part 512 can be a strong magnetic block embedded in the bottom of the positioning member 51, which can achieve a detachable connection through magnetic adsorption. The connection strength can be adjusted by selecting magnetic blocks with different magnetic parameters, and it has the advantage of a holeless connection, avoiding damage to the surface of the loading platform 4.

[0026] Two right-angle clamps are respectively set on two positioning parts 51, and the right-angle clamps are located on the top of the corresponding material platform 4. The two right-angle clamps are set opposite to each other, and the two right-angle sides of the right-angle clamps are respectively used to fit with the adjacent two sides of the template.

[0027] Two right-angle clamps are connected to two positioning parts 51 respectively, with their right-angle vertices on the same horizontal line to ensure symmetry in their relative arrangement. The right-angle clamps can be made of 45# steel with a heat treatment process. The lengths of the two right-angle sides are set according to actual needs, and the inner edges are rounded to ensure a tight fit with the adjacent sides of the template while preventing scratches on the template edges. The inner surface roughness of the right-angle sides reaches Ra1.6 to ensure the flatness of the mating surface and improve the verticality accuracy of the template positioning.

[0028] The scale 53 is connected between the two positioning elements 51, and the scale 53 is adapted to be perpendicular to the feed direction of the cutting line 3.

[0029] The scale 53 serves as the measurement reference for the tool entry position. For example, the scale 53 can be made of 3mm thick stainless steel plate, with a blackened surface and laser-engraved scale with an accuracy of 0.1mm, facilitating accurate reading of position parameters. The scale 53 can be connected to the two positioning parts 51 by bolts. The scale 53 has through holes at both ends, and the positioning parts 51 have corresponding threaded blind holes. The scale 53 is fixed to the positioning parts 51 by hexagonal socket head cap screws, and spring washers are added at the connection to prevent loosening. In other examples, the positioning parts 51 can have slots that match the thickness of the scale 53. The two ends of the scale 53 are inserted into the slots, and set screws are provided on the side of the slots. The scale 53 can be fixed by tightening the screws, facilitating the replacement or length adjustment of the scale 53.

[0030] The length of the scale 53 is determined according to the distance between the two material carriers 4, and can be set to 300mm-700mm. After installation, it needs to be calibrated by a level to ensure that the upper surface of the scale 53 is in a horizontal state, and that the axis of the scale 53 is strictly perpendicular to the cutting direction of the cutting line 3, with a perpendicularity error not exceeding 0.02mm / m.

[0031] The laser plumb line 54 can be movably mounted on the scale 53, and the laser of the laser positioning instrument is adapted to be parallel to the feed direction of the cutting line 3.

[0032] The laser plumb line 54 projects the feed position determined on the scale 53 onto the cutting line 3. It employs a high-precision portable laser to ensure clear observation of the laser spot even under ambient lighting conditions in the workshop. In some examples, the laser plumb line 54 can be mounted on the scale 53 via a sliding assembly. This assembly may include a U-shaped slider 541 that matches the scale 53. The inner side of the slider 541 is equipped with a wear-resistant nylon pad to ensure smooth sliding while preventing scratches on the surface of the scale 53. The laser emission direction of the laser plumb line 54 is calibrated to ensure that the laser beam is parallel to the feed direction of the cutting line 3.

[0033] In actual execution, during installation, the two positioning parts 51 are fixed to the loading tables 4 on both sides of the cutting line 3 via the connecting part 512. A level is used to calibrate the scale 53, ensuring that the scale 53 is strictly perpendicular to the cutting direction of the cutting line 3. The template is placed on the loading table 4, ensuring that its adjacent sides are tightly fitted with the right-angled edges of the right-angle clamp. At this point, the edge of the template is perpendicular to the cutting direction of the cutting line 3. According to the processing drawing requirements, the cutting position is determined on the scale 53, and the laser plumb line 54 is slid to this position and locked. The laser plumb line 54 is activated, and the loading table 4 is moved so that the part of the template to be cut is aligned with the position indicated by the laser beam. At this point, the cutting direction of the cutting line 3 is parallel to the cutting reference edge of the template and the position is accurate, completing the positioning preparation work before cutting.

[0034] According to the wire cutting auxiliary device 5 provided in the embodiments of this application, the entire wire cutting auxiliary device 5 is fixed by the positioning member 51, and the template is tightly aligned with the right angle by the right angle clamp. After tightening the pressure plate on the loading table 4, it can be ensured that the right angle of the template is perpendicular to the cutting direction of the cutting line 3. Then, the cutting position of the template is determined by the ruler 53, and the laser plumb line 54 is fixed to that position. Then, the loading table 4 is moved so that the laser and the cutting line 3 coincide, which can ensure the accuracy of the cutting position. This device greatly reduces the difficulty of operation for workers, improves the processing accuracy, and reduces the probability of material waste.

[0035] Please see Figure 2 , Figure 3 and Figure 4 According to some embodiments of this application, the laser plumb line 54 is provided with a slider 541 sleeved on the scale 53, and the slider 541 is provided with a locking knob, which is used to fix the laser plumb line 54 at any position of the scale 53.

[0036] The slider 541 is fitted around the scale 53, and its shape matches the cross-section of the scale 53. If the scale 53 is rectangular, the inner hole of the slider 541 is also rectangular, and there is an appropriate gap between them to ensure that the slider 541 can slide smoothly along the scale 53. The slider 541 can be made of engineering plastic (such as nylon 66) or metal (such as brass). When engineering plastic is used, it has the characteristics of light weight and low coefficient of friction, which can reduce wear on the surface of the scale 53; when brass is used, it has higher strength and is suitable for long-term high-frequency use.

[0037] A locking knob is mounted on the slider 541, with one end passing through the side wall of the slider 541 and threadedly connected to it. The locking knob can be made of plastic or metal; a plastic knob offers a more comfortable feel, while a metal knob is more durable. When adjusting the position of the laser plumb line 54, the locking knob is released, allowing the slider 541 to slide freely along the scale 53. Once the laser plumb line 54 reaches the desired position, the locking knob is tightened. The end of the locking knob presses firmly against the surface of the scale 53, using friction to fix the slider 541 relative to the scale 53, thus securing the laser plumb line 54 at that position on the scale 53.

[0038] The cooperation structure between the slider 541 and the locking knob makes the position adjustment of the laser plumb line 54 on the scale 53 more convenient and stable. The slider 541 is fitted over the scale 53, ensuring the guidance of the laser plumb line 54 during sliding and preventing deviation; while the locking knob can reliably fix the laser plumb line 54 in any position, ensuring that the laser plumb line 54 will not change position due to vibration or other factors during processing, further improving the accuracy of the tool feed position positioning.

[0039] Please see Figures 2 to 4According to some embodiments of this application, the scale 53 has a scale mark on the side facing the template, and the laser plumb line instrument 54 may be provided with a laser plumb line position pointer 542 corresponding to the scale mark.

[0040] The scale markings are located on the side of the scale 53 facing the template, which is the side easily visible to the operator when placing the template and adjusting the laser plumb line 54. The scale markings can be made using laser engraving, etching, or printing. The unit of measurement can be millimeters, or other units can be used depending on actual processing needs, such as 0.5 millimeters per interval. The numbers on the scale markings are clearly visible, and the color can contrast with the scale 53 itself; for example, if the scale 53 is silver-white, the scale markings can be black, facilitating quick and accurate reading of values ​​by the operator.

[0041] The laser plumb line position pointer 542 is mounted on the laser plumb line instrument 54 and corresponds to the scale markings, meaning the tip of the pointer points to the scale markings, accurately indicating the position of the laser plumb line instrument 54 on the scale 53. The pointer can be made of bent metal or integrally molded from plastic onto the outer shell of the laser plumb line instrument 54. The pointer's length should not be too long, ideally not obscuring the scale markings while accurately pointing to them. The tip of the pointer can be sharpened to further improve pointing accuracy. The pointer can be connected to the laser plumb line instrument 54 by welding, bonding, or fixing with screws, ensuring that the pointer does not loosen or deviate during the movement of the laser plumb line instrument 54.

[0042] The scale markings provide an intuitive numerical reference for determining the tool entry position, while the laser plumb line position pointer 542 can accurately correspond the position of the laser plumb line instrument 54 with the scale markings. This allows the operator to quickly move the laser plumb line instrument 54 to the preset tool entry position by observing the scale indicated by the pointer when adjusting the laser plumb line instrument 54, reducing adjustment time and improving the convenience of operation.

[0043] Please see Figures 1 to 4 According to some embodiments of this application, the main body 511 of the positioning member 51 is located above the material carrier 4, the connecting part 512 is located at the bottom of the main body 511, and the vertical surface of the main body 511 is provided with a strip groove (not shown in the figure) extending along the height direction. The two ends of the scale 53 are respectively fixed in the strip groove of the two positioning members 51 by bolts. The strip groove is used to adjust the installation height of the scale 53.

[0044] The main body 511, as the main structural part of the positioning component 51, is located above the loading platform 4. Its material can be consistent with that of the positioning component 51 as a whole, such as aluminum alloy profiles or steel plates, and it has a certain structural strength to support components such as the right-angle clamp and the scale 53. The shape of the main body 511 can be designed according to actual needs. It can be a cubic block structure, and its facade must be flat to allow for the opening of strip grooves and to ensure the verticality of the scale 53 after installation. Specifically, this facade can be a surface that is opposite to the feed direction of the cutting line 3.

[0045] The connecting part 512 is located at the bottom of the main body 511 and is used to achieve a detachable connection between the positioning member 51 and the loading platform 4. The structure of the connecting part 512 can be adapted according to the type of the connecting part 512. For example, when the connecting part 512 is a bolt connection, the connecting part 512 can be a flange extending outward from the bottom of the main body 511, with holes provided on the flange to mate with bolts; when the connecting part 512 is a magnetic type, the connecting part 512 can integrate a strong magnet, etc.

[0046] The strip groove is formed on the facade of the main body 511, extending along the height direction. Its length is determined according to the required height adjustment range of the scale 53, and its width is slightly larger than the diameter of the bolt fixing the scale 53, usually 1-2mm larger than the bolt diameter, to ensure that the bolt can slide smoothly in the groove. The edges of the strip groove can be chamfered to avoid scratching operators or bolts.

[0047] The two ends of the scale 53 are fixed to the slots of the two positioning parts 51 by bolts. Specifically, the cross-section of the slot can be T-shaped. Through holes are opened at both ends of the scale 53 to mate with the bolts. The bolts pass through the through holes of the scale 53, and the nuts are located in the slots. The scale 53 is initially fixed by engaging with the nuts. When it is necessary to adjust the installation height of the scale 53, the nuts are loosened, and the bolt nuts can move along the height direction of the slots, thereby moving the scale 53 up and down until the scale 53 reaches the appropriate height. Then, the nuts are tightened so that the bolts are pressed tightly against the edge of the T-slots, thus fixing the scale 53 at that height.

[0048] The groove design allows the installation height of the scale 53 to be flexibly adjusted according to actual processing needs. For example, when processing templates of different thicknesses, the height of the scale 53 can be adjusted to ensure that the laser emitted by the laser plumb line 54 is accurately projected onto the template and cutting line 3, guaranteeing positioning accuracy. At the same time, this adjustment method is simple to operate, requiring no disassembly of the positioning component 51, greatly improving the adaptability and ease of use of the device.

[0049] According to some embodiments of this application, the facade of the main body 511 is provided with a calibration scale, which corresponds at least partially to the scale markings of the scale 53.

[0050] The calibration scale is located on the facade of the main body 511, and is made using laser engraving or etching processes. The line width is 0.1-0.2mm, and the color is chosen to contrast sharply with the facade of the main body 511. If the main body 511 is the original metallic color, the calibration scale is black to ensure clear visibility in complex lighting conditions in the workshop. The length of the calibration scale does not need to be exactly the same as the measuring range of the scale 53; only a section needs to be set to cover some of the key scale markings on the scale 53.

[0051] The calibration scale corresponds at least partially to the scale markings on the ruler 53. For example, if the ruler 53 has scale markings such as 0mm, 50mm, and 100mm, the calibration scale can be set to correspondingly have 0mm and 50mm markings, forming a correspondence with these markings on the ruler 53. Each mark on the calibration scale can also be marked, such as a triangle marking at the 0mm position on the ruler 53 and a circle marking at the 50mm position, to facilitate precise alignment with the scale markings on the ruler 53. The purpose of the calibration scale is to calibrate the scale position of the scale 53, preventing the scale 53 from shifting along the length direction during installation or adjustment. By aligning only some corresponding scales, it is possible to effectively determine whether the scale 53 has shifted along the length direction, ensuring the accuracy of the scale 53, and thus ensuring that the laser plumb line 54 accurately determines the infeed position based on the scale 53, improving the positioning reliability of the device.

[0052] Please see Figures 2 to 4 According to some embodiments of this application, a right-angle clamp can be disposed on the lower side of the main body 511. The right-angle clamp may include a first clamping plate 521 and a second clamping plate 522 that are perpendicular to each other. The first clamping plate 521 is adapted to be perpendicular to the cutting direction of the cutting line 3, and the second clamping plate 522 is fixedly connected to the main body 511.

[0053] The right-angle clamp is located on the lower side of the main body 511, that is, the right-angle clamp is installed on the side of the main body 511 near the material carrier 4. This arrangement can be closer to the position where the template is placed, making it easier for the adjacent sides of the template to fit and be positioned with the right-angle clamp.

[0054] The right-angle clamp includes a first clamping plate 521 and a second clamping plate 522 that are perpendicular to each other. They can be manufactured using a one-piece molding process, such as casting or welding to form a right-angle structure, or they can be fixed by bolts, ensuring that the perpendicularity error between the two does not exceed 0.02mm. The first clamping plate 521 and the second clamping plate 522 can be made of stainless steel, which has good rigidity and wear resistance, and ensures flatness when fitted with the template.

[0055] The first clamping plate 521 is adapted to be perpendicular to the feed direction of the cutting line 3, so that when one side of the template is attached to the first clamping plate 521, that side of the template can remain perpendicular to the feed direction of the cutting line 3, providing an important benchmark for the accurate positioning of the template and avoiding the skewing of the cutting line 3 due to deviations in the template placement angle. The second clamping plate 522 is fixedly connected to the main body 511. The connection method can be welding. When both the main body 511 and the second clamping plate 522 are made of metal, welding can ensure the firmness of the connection. Alternatively, a bolt connection can be used, with corresponding threaded holes on the second clamping plate 522 and the main body 511, and the two can be fixed by bolts. This method facilitates the disassembly and replacement of the right-angle clamp.

[0056] According to some embodiments of this application, a removable wear-resistant pad is provided on the side of the first card plate 521 facing the second card plate 522, and the surface of the wear-resistant pad is provided with anti-slip texture.

[0057] The wear-resistant pad is located on the side of the first clamping plate 521 facing the second clamping plate 522, that is, the side that contacts the sample. The wear-resistant pad can be made of high-strength wear-resistant materials, such as polytetrafluoroethylene (PTFE), ceramic, or hard alloy. PTFE pads have good wear resistance and self-lubricating properties, and are relatively soft, preventing scratches on the sample surface; ceramic pads have high hardness and extremely strong wear resistance, suitable for long-term, high-frequency use; hard alloy pads combine high hardness and high wear resistance, resulting in a long service life.

[0058] The wear-resistant pad and the first clamping plate 521 are detachably connected. In some examples, through holes are made on the wear-resistant pad and the first clamping plate 521 respectively, and the pad is fixed to the first clamping plate 521 with hexagonal bolts. This method of connection is firm, easy to disassemble, and convenient for replacing the pad. In other examples, a locking protrusion is provided on the first clamping plate 521, and a corresponding locking groove is provided on the wear-resistant pad. The detachable connection is achieved by the cooperation of the locking protrusion and the locking groove. The operation is simple and the pad can be installed and removed without tools. In still other examples, when the first clamping plate 521 is made of iron, a magnetic block can be embedded in the wear-resistant pad. It is attracted to the first clamping plate 521 by magnetic force. The disassembly is convenient and no connection hole is left on the first clamping plate 521. The surface of the wear-resistant pad has anti-slip textures, which can take various forms, such as grid patterns, stripes, or dotted raised areas. Grid patterns are formed by intersecting perpendicular lines, providing anti-slip protection in two directions. Stripes can be set along the length of the first clamping plate 521 to increase friction when adhering to the template. The dotted raised areas are evenly distributed to effectively prevent the template from sliding during the application process. The depth of the anti-slip textures can be 0.3-0.5mm, ensuring anti-slip effectiveness without causing the template and pad to not adhere tightly due to excessive depth.

[0059] The wear-resistant pads prevent direct contact between the first clamping plate 521 and the template, reducing wear caused by long-term friction and extending its service life. The detachable design allows for easy replacement of the pads when they wear down to a certain extent, eliminating the need to replace the entire first clamping plate 521 and reducing maintenance costs. The anti-slip texture increases the friction between the pads and the template, preventing displacement of the template due to vibration or other factors after positioning or during cutting, further ensuring the stability and accuracy of template positioning.

[0060] Please see Figures 1 to 4 This application also provides a wire cutting device 100, which includes: a base 1, a movable platform 2, a cutting wire 3, two material carriers 4, and a wire cutting auxiliary device 5 as described in any of the above technical solutions.

[0061] It should be noted that, since the wire cutting equipment 100 provided in this application embodiment includes the wire cutting auxiliary device 5 of any of the above technical solutions, it has the technical features and beneficial effects of the wire cutting auxiliary device 5 of any of the above technical solutions, which will not be repeated here.

[0062] The base 1, serving as the fundamental support component of the entire equipment, is typically made of cast iron and undergoes aging treatment to eliminate internal stress, ensuring structural stability and preventing deformation. Guide rails are machined onto the upper surface of the base 1 to guide the movement of the movable platform 2. The movable platform 2 is movably mounted on the base 1, and its connection with the base 1 is typically a sliding fit or a rolling fit. When a sliding fit is used, the bottom of the movable platform 2 has a slider 541 adapted to the guide rail of the base 1, and lubricant is applied between the slider 541 and the guide rail to reduce friction. When a rolling fit is used, ball bearings or rollers can be placed between them to make the movement of the movable platform 2 smoother and reduce energy consumption. The movable platform 2 can be driven by a servo motor in conjunction with a ball screw. The motor drives the screw to rotate, causing the movable platform 2 to move precisely along the guide rail of the base 1, meeting the positional accuracy requirements of wire EDM. The movable platform 2 can move in at least two directions. For example, the movable platform 2 can include a first platform and a second platform. The first platform is movably mounted on the base 1 longitudinally, and the second platform is movably mounted on the first platform laterally, thereby driving the loading table 4 to move freely in the horizontal direction.

[0063] The cutting wire 3 is vertically positioned above the movable platform 2. The cutting wire 3 is typically made of molybdenum wire with a diameter between 0.08-0.2 mm, possessing high strength and high wear resistance. Both ends of the cutting wire 3 are connected to the feed reel and take-up reel of the equipment, respectively. The rotation of the feed and take-up reels drives the cutting wire 3 to move at high speed, achieving the cutting of the sample. The tension of the cutting wire 3 can be adjusted via a tensioning mechanism to ensure that the cutting wire 3 does not slacken during the cutting process, guaranteeing cutting accuracy.

[0064] Two loading platforms 4 are installed on the top of the movable platform 2, and the two loading platforms 4 are distributed on both sides of the cutting line 3. The loading platforms 4 are provided with fixed grooves 41 extending along the cutting direction of the cutting line 3.

[0065] Two loading platforms 4 are installed on top of the movable platform 2 and can be fixed by bolt connection to ensure that the loading platforms 4 will not shift during the movement of the movable platform 2. The two loading platforms 4 are distributed on both sides of the cutting line 3, and the spacing is determined according to the size of common templates. The top surface of the loading platform 4 needs to be machined flat to provide a stable support surface for the placement of the template. The loading platform 4 is provided with a fixing groove 41 extending along the feed direction of the cutting line 3. The cross-sectional shape of the fixing groove 41 can be T-shaped, rectangular, or dovetail-shaped. The function of the fixing groove 41 is to provide an installation position for the positioning component 51 of the wire EDM auxiliary device 5, ensuring that the positioning component 51 can be adjusted in position along the feed direction.

[0066] It should be noted that the fixing groove 41 can also provide a mounting point for the pressure plate, making it easier to fix the pressure plate.

[0067] The two positioning parts 51 are detachably connected to the corresponding fixing grooves 41 via the connecting parts 512, and the two right-angle clamps are located on the top surfaces of the two material loading platforms 4 respectively.

[0068] Two positioning components 51 are detachably connected to the corresponding mounting slots 41 of the material carrier 4 via their connecting parts 512. When the connecting part 512 is a bolt structure, the bolt passes through the connecting part 512 of the positioning component 51 and extends into the mounting slot 41, cooperating with the nut in the mounting slot 41 to fix the positioning component 51; when the connecting part 512 is a snap-fit ​​structure, the connecting part 512 can snap into the mounting slot 41, and is fixed by its own elastic force or locking parts. This detachable connection method facilitates the installation, disassembly, and position adjustment of the wire cutting auxiliary device 5. Two right-angle clamps are located on the top surfaces of the two material carriers 4 respectively, keeping them in contact with the top surfaces of the material carriers 4 to ensure that the positioning reference of the template corresponds to the position of the material carrier 4.

[0069] In actual execution, the sample to be processed is first placed on two loading platforms 4, with the adjacent sides of the sample aligned with the right-angled edges of the two right-angle clamps. The right-angle clamps achieve initial positioning of the sample, ensuring that the sample's placement angle is perpendicular to the cutting direction of the cutting line 3. According to the processing requirements, the cutting position is determined using a ruler 53 and a laser plumb line 54. The position of the laser plumb line 54 on the ruler 53 is adjusted, and the movable platform 2 is adjusted so that the laser beam of the laser plumb line 54 is aligned with the cutting line 3. The drive mechanism of the movable platform 2 is activated, moving it along the guide rail of the base 1, gradually bringing the sample closer to the cutting line 3 until the sample's cutting position is aligned with the cutting line 3. Subsequently, the cutting line 3 moves at high speed driven by the feed and take-up reels, while the movable platform 2 moves along a preset trajectory, and the cutting line 3 cuts the sample. During the cutting process, the precise positioning of the wire cutting auxiliary device 5 ensures that the movement trajectory of the cutting line 3 remains straight, guaranteeing the processing accuracy of the sample.

[0070] According to the wire cutting equipment 100 provided in this application embodiment, by integrating the wire cutting auxiliary device 5, the problems of low processing accuracy and material waste caused by the reliance on visual positioning by operators in traditional wire cutting equipment 100 are effectively solved. The high-precision movement of the movable platform 2 provides precise position control for the cutting process, and the fixing groove 41 on the loading table 4 facilitates the installation and position adjustment of the wire cutting auxiliary device 5. The wire cutting auxiliary device 5 ensures the accurate positioning of the template, thereby reducing the difficulty of operating the entire equipment and improving the processing accuracy. At the same time, the detachable connection between the components facilitates the maintenance and upkeep of the equipment and extends its service life.

[0071] Please see Figures 1 to 4 According to some embodiments of this application, the fixing groove 41 can be a T-shaped slot that passes through the material loading platform 4, and the connecting part 512 is a T-shaped plug that engages with the T-shaped slot.

[0072] The T-shaped slot can be a through-hole of the loading platform 4, that is, extending from one end of the loading platform 4 to the other end, running through the entire length of the loading platform 4. Its cross-section is T-shaped, specifically, it consists of a horizontal slot and a vertical slot. The horizontal slot is located inside the loading platform 4 and its width is greater than that of the vertical slot. The vertical slot is connected to the top surface of the loading platform 4 and its width is slightly smaller than that of the horizontal slot.

[0073] The T-shaped plug, serving as the connecting part 512, is shaped to match the T-shaped slot. It also consists of a horizontal plug and a vertical plug. The width of the horizontal plug matches the width of the horizontal groove of the T-shaped slot, and the width of the vertical plug matches the width of the vertical groove of the T-shaped slot. The fit clearance is controlled between 0.1-0.2mm to ensure smooth engagement while preventing wobbling caused by an excessively loose fit. The T-shaped plug and the main body 511 of the positioning component 51 can be manufactured using a one-piece molding process. For example, if the positioning component 51 is made of metal, the T-shaped plug can be formed by casting or forging. Alternatively, they can be connected by welding, with the T-shaped plug welded to the bottom of the main body 511 to ensure a secure connection.

[0074] Align the horizontal plug of the T-shaped plug with the horizontal slot of the T-shaped slot, and the vertical plug with the vertical slot. Insert the T-shaped plug into the T-shaped slot from one end of the loading platform 4. Then slide the positioning member 51 along the length of the T-shaped slot until it reaches the appropriate position. Since the width of the horizontal slot of the T-shaped slot is greater than that of the vertical slot, the horizontal plug of the T-shaped plug cannot pass through the vertical slot, thus achieving a snap-fit ​​fixation between the two and preventing the positioning member 51 from falling off the top surface of the loading platform 4.

[0075] This T-shaped slot and T-shaped plug mating structure features a secure connection, precise positioning, and convenient adjustment. The through-hole T-shaped slot allows the positioning element 51 to be adjusted over a wide range of positions along the length of the loading table 4 (i.e., the feed direction of the cutting line 3) to adapt to the processing requirements of templates of different sizes. The T-shaped mating form ensures that the positioning element 51 is stable in the vertical direction and horizontally perpendicular to the feed direction, preventing displacement and providing a reliable guarantee for the precise positioning of the wire EDM auxiliary device 5. At the same time, the snap-fit ​​mating method allows the positioning element 51 to be installed and removed without tools; simply inserting or removing the T-shaped plug from the T-shaped slot greatly improves the convenience of operation.

[0076] According to some embodiments of this application, the lateral end of the T-shaped plug is provided with an elastic protrusion, and the T-shaped slot is provided with a positioning hole that matches the elastic protrusion.

[0077] The elastic protrusion is located at the lateral end of the T-type plug and can be made of elastic materials such as rubber or silicone, or a metal spring structure. When rubber or silicone is used, the elastic protrusion is fixed in a pre-set groove at the lateral end by vulcanization or bonding. Its shape can be hemispherical, cylindrical, or trapezoidal, possessing good elastic deformation capability, shrinking under compression and returning to its original shape after the pressure is removed. When a metal spring is used, one end of the spring is fixedly connected to the lateral end (such as by welding or integral molding), and the other end is bent upward to form a protrusion with a suitable elastic coefficient, ensuring that the protrusion can flexibly expand and contract.

[0078] The positioning holes are formed within the T-shaped slot and are adapted to the shape and size of the elastic protrusion. For example, when the elastic protrusion is hemispherical, the positioning hole can be a hemispherical groove; when the elastic protrusion is cylindrical, the positioning hole can be a circular through hole or a blind hole, with a depth slightly greater than the height of the elastic protrusion to ensure that the elastic protrusion can be smoothly engaged. The number of positioning holes can be set according to actual needs, usually multiple, distributed at intervals along the length of the T-shaped slot, with intervals of 50mm, 100mm, etc., or specific intervals can be set according to common template sizes to meet the positioning needs of different positions.

[0079] When the T-shaped plug slides in the T-shaped slot, the elastic protrusion contracts under the pressure of the inner wall of the slot. When the T-shaped plug slides until the elastic protrusion is aligned with a positioning hole, the elastic protrusion extends into the positioning hole under its own elastic force, realizing the relative positioning of the T-shaped plug and the T-shaped slot. If you want to continue sliding the T-shaped plug, you need to apply a certain external force to make the elastic protrusion disengage from the positioning hole and contract again. This structure, where the elastic protrusion and positioning hole work together, provides effective positioning after the T-shaped plug slides to the desired position, preventing it from sliding off during processing due to equipment vibration or other factors. This further enhances the stability of the connection between the positioning component 51 and the loading platform 4. The multiple positioning holes provide the positioning component 51 with multiple fixed position options, making positioning adjustments more precise and allowing for quick fixation of the positioning component 51 in a preset, suitable position, thus improving operational efficiency. Simultaneously, the elasticity of the protrusion means that the positioning and unlocking processes can be completed without tools, simply by applying appropriate manual force, making operation convenient.
