Description

Technical Field

[0001] This utility model relates to the technical field of wire EDM machine tool processing equipment, and in particular to an adjustable guide device. Background Technology

[0002] Wire EDM machines, with their high-precision machining capabilities, occupy an important position in many fields such as mold manufacturing and precision instrument manufacturing. During the machining process, the electrode wire, as a key component for material cutting, directly determines the dimensional accuracy, surface quality, and machining efficiency of the workpiece. Traditional wire EDM machine guide devices mostly adopt a fixed structure design. This structure makes it difficult to achieve rapid and precise adjustments when facing machining tasks with different shapes, sizes, and precision requirements. For example, when machining complex curved surface molds, the inability to flexibly adjust the angle and position of the guide makes it difficult for the electrode wire's movement trajectory to precisely match the design requirements, leading to increased machining errors and a higher scrap rate. Simultaneously, in the long-term use of fixed-structure guides, the electrode wire and the guide's inner wall experience significant wear, especially during angled machining. The angle formed between the electrode wire and the guide's inner wall increases wear on the guide's opening, shortening its lifespan and affecting the guiding stability of the electrode wire due to wear gaps, further reducing machining accuracy. Some guides cannot effectively adapt to wires of different diameters and shapes. When the wire diameter changes, it may lead to guiding instability, affecting cutting quality. Furthermore, existing guides have poor adjustability, making it difficult to flexibly adjust them according to actual processing needs and failing to meet diverse cutting tasks. Therefore, it is necessary to develop an adjustable guide device to address these shortcomings. Utility Model Content

At the same time, the first steering seat of the upper guide component and the slider, and the second steering seat of the lower guide component and the slide rail are rotatably connected, so that the upper and lower guides can be flexibly adjusted in the horizontal and vertical directions to meet diverse cutting tasks.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Refer to the attached diagram. Figure 1 This is a three-dimensional structural diagram of the adjustable guide device of this utility model; Figure 2 This is a schematic diagram of the main structure of the adjustable guide device of this utility model; Figure 3 This is a schematic diagram of the right side of the adjustable guide device of this utility model; Figure 4 This is a schematic diagram of the left cross-sectional structure of the adjustable guide device of this utility model; Figure 5 for Figure 2 Schematic diagram of the structure at point A in the middle.

[0030] In one specific implementation, such as Figures 1-5 As shown, an adjustable guide device includes a vertical plate 1, which is vertically fixed to a wire EDM machine tool to ensure stable installation and provide stable support for the guide device. The wire EDM machine tool is not shown in the figure. An upper guide assembly 2 is provided at the upper end of the vertical plate 1, and the upper guide assembly 2 is vertically installed inside the vertical plate 1 via a slider 201. A first drive assembly 3 is provided at the top of the vertical plate 1, which is screwed to the slider 201 and used to drive the slider 201 to move the upper guide assembly 2 up and down. A lower guide assembly 4 is provided at the lower end of the vertical plate 1, and the lower guide assembly 4 is horizontally installed inside the vertical plate 1 via a slide rail 401. A second drive assembly 5 is provided at the lower end of the slide rail 401, and the second drive assembly 5 drives the slide rail 401 to move the lower guide assembly 4 horizontally. Because of the different thicknesses of the workpieces, the distance between the upper guide 205 and the lower guide 405 does not need to be adjusted during processing. This is to avoid the electrode wire vibrating too much when the distance between the upper guide 205 and the lower guide 405 is too large, which would affect the processing quality. If the distance between the upper guide 205 and the lower guide 405 is too small, it would affect the discharge effect of the electrode wire.

[0031] In one specific implementation, such as Figures 1-5As shown, the upper guide assembly 2 includes a first steering seat 202, a first mounting seat 203, a clamping assembly 6, a first telescopic rod 204, a guiding assembly 7, and an upper guide 205. The back of the first steering seat 202 has an arc-shaped structure, which is rotatably connected to the cylindrical structure at the front end of the slider 201. The first mounting seat 203 is fixed to the front end face of the first steering seat 202, and the upper guide 205 is mounted on the bottom end of the first mounting seat 203. The back of the first mounting seat 203 is hinged to the first telescopic rod 204, and its other end is hinged to the lower end face of the slider 201. By adjusting the length of the first telescopic rod 204, the first mounting seat 203 rotates around the rotational connection point between the first steering seat 202 and the slider 201, thereby adjusting the angle of the upper guide 205. The first mounting seat 203 is a hollow structure, with two sets of horizontally arranged clamping assemblies 6 inside, used to clamp the electrode wire, located on the upper and lower sides of the first mounting seat 203 respectively. A guide component 7 is provided between the two sets of clamping components 6 and is fixedly installed on the back of the first mounting base 203.

[0032] In one specific implementation, such as Figures 1-5 As shown, the lower guide assembly 4 includes a second steering seat 402, a second mounting seat 403, a second telescopic rod 404, and a lower guide 405. The back of the second steering seat 402 has an arc-shaped structure, which is rotatably connected to the cylindrical structure at the front end of the slide rail 401. The second mounting seat 403 is fixed to the front end face of the second steering seat 402, and the lower guide 405 is mounted on the upper end of the second mounting seat 403. The back of the second mounting seat 403 is hinged to the second telescopic rod 404, and its other end is hinged to the upper end face of the slide rail 401. By adjusting the length of the second telescopic rod 404, the second mounting seat 403 rotates around the rotational connection point between the second steering seat 402 and the slide rail 401, thereby adjusting the angle of the lower guide 405. The second mounting seat 403 has a hollow structure and contains a clamping assembly 6 for holding the electrode wire, located at the lower end of the lower guide 405.

[0033] In one specific implementation, such as Figures 1-5 As shown, the first drive assembly 3 includes a lead screw 301 and a first motor 302; the vertical plate 1 is provided with a sliding groove, and the slider 201 is slidably installed in the sliding groove through a T-shaped step and screwed to the lead screw 301. The first motor 302 is fixedly installed at the top of the vertical plate 1 and drives the slider 201 to move up and down by driving the lead screw 301 to rotate.

[0034] In one specific implementation, such as Figures 1-5As shown, the second drive assembly 5 includes a gear 501, a rack 502, and a second motor 503; the lower end of the upright plate 1 is provided with a square groove, and the slide rail 401 is slidably installed in the square groove through a T-shaped step. The lower end of the slide rail 401 is fixedly provided with a rack 502, and the lower end of the rack 502 is meshed with the gear 501. The second motor 503 is installed on one side of the gear 501. The second motor 503 drives the gear 501 to rotate, so that the slide rail 401 slides horizontally along the direction of the square groove.

[0035] In one specific implementation, such as Figures 1-5 As shown, the clamping assembly 6 includes a clamping roller 601, a bracket 602, and a cylinder 603. Two clamping rollers 601 are located on either side of the electrode wire. The bracket 602 is located on the back of the clamping roller 601. One end of the bracket 602 is rotatably connected to the clamping roller 601, and the other end is connected to the output shaft of the cylinder 603. The cylinder 603 drives the clamping roller 601 to move closer or further away from each other. When the clamping assembly 6 is installed in the first mounting base 203, the two cylinders 603 are fixed to the inner walls on both sides of the first mounting base 203. When the clamping assembly 6 is installed in the second mounting base 403, the two cylinders 603 are fixed to the inner walls on both sides of the second mounting base 403. The electrode wire is clamped according to its diameter. The air inlet and outlet ports of the multiple cylinders 603 are respectively installed on a synchronizing valve to ensure consistent air intake and exhaust speeds.

[0036] In one specific implementation, such as Figures 1-5 As shown, the guiding assembly 7 includes a fixing block 701 and a conduit 702. The fixing block 701 is installed inside the first mounting base 203 and its back is fixedly connected to the first mounting base 203. The fixing block 701 has a vertical hollow conduit 702 inside, and the conduit 702 is coaxially arranged with the upper guide 205. This makes it easier for the electrode wire to enter the guide through the conduit 702, facilitating the installation of the electrode wire. Furthermore, the electrode wire passing through the conduit 702 prevents the clamping assemblies on the upper and lower sides from twisting when clamping the motor wire.

[0037] In one specific implementation, such as Figures 1-5 As shown, the upper guide 205 and the lower guide 405 are coaxially arranged. This allows the electrode wire to easily pass through the upper and lower guides 405, and the coaxial arrangement reduces wear on the upper and lower guides 405 by the electrode wire, thus increasing the service life of the upper and lower guides 405.

[0038] In one specific implementation, such as Figures 1-5As shown, first connecting plates 206 are provided on both sides of the first steering seat 202 and the slider 201. The two ends of the first connecting plates 206 are fixedly connected to the first steering seat 202 and the slider 201 by rotatable screws. A ball bearing is provided between the screw and the first connecting plate 206, so that the first connecting plate 206 can rotate freely relative to the screw, further enhancing the flexibility of rotation between the first steering seat 202 and the slider 201.

[0039] In one specific implementation, such as Figures 1-5 As shown, second connecting plates 406 are provided on both sides of the second steering seat 402 and the slide rail 401. The two ends of the second connecting plates 406 are fixedly connected to the second steering seat 402 and the slide rail 401 respectively by rotatable screws. A ball bearing is provided between the screw and the second connecting plate 406, so that the second connecting plate 406 can rotate freely relative to the screw, further enhancing the flexibility of rotation between the second steering seat 402 and the slide rail 401.

[0040] The operation of this adjustable guide device is as follows: Before wire EDM, the starting position and trajectory of the electrode wire are determined according to the design requirements of the workpiece. The electrode wire is passed through the upper guide assembly 2 and the lower guide assembly 4, ensuring smooth passage of the electrode wire through the guide tube 702 of the guiding assembly 7 and the upper and lower guides 405. The clamping roller 601 is driven by the starting cylinder 603 to clamp and fix the electrode wire. During processing, the distance between the upper guide 205 and the lower guide 405 needs to be adjusted according to the thickness of the workpiece. The first motor 302 is started, which drives the lead screw 301 to rotate, driving the slider 201 to move up and down along the slide groove of the vertical plate 1. The slider 201 drives the upper guide assembly 2 to move up and down as a whole, thereby adjusting the distance between the upper guide 205 and the lower guide 405. During the adjustment process, the first telescopic rod 204 plays an auxiliary support and guiding role, ensuring the stability of the movement of the upper guide assembly 2. When angle machining of the workpiece is required, the horizontal distance between the upper guide 205 and the lower guide 405 needs to be adjusted. The second motor 503 is started, driving the gear 501 to rotate. The gear 501 meshes with the rack 502, driving the slide rail 401 to slide horizontally along the square groove of the vertical plate 1. The slide rail 401 drives the lower guide assembly 4 to move horizontally as a whole, thereby achieving precise horizontal adjustment of the lower guide 405. During the adjustment process, the second telescopic rod 404 provides auxiliary support and guidance, ensuring the stability of the movement of the lower guide assembly 4. After the horizontal distance between the lower guide 405 and the upper guide 205 is adjusted, the angles of the upper guide 205 and the lower guide 405 are adjusted respectively. The length of the first telescopic rod 204 is adjusted so that the first mounting base 203 rotates around the rotational connection point between the first steering seat 202 and the slider 201, thereby adjusting the angle of the upper guide 205. Adjusting the length of the second telescopic rod 404 allows the second mounting base 403 to rotate around the rotational connection point between the second steering seat 402 and the slide rail 401, thereby adjusting the angle of the lower guide 405. After adjustment, the upper guide 205 and the lower guide 405 remain coaxially aligned. During angle adjustment, the clamping assembly 6 maintains stable clamping of the electrode wire, and the guiding assembly 7 ensures the electrode wire's movement trajectory. After adjusting the position and angle of the upper and lower guide assemblies 4, the wire EDM machine is started for processing. During processing, the electrode wire passes through the guide tube 702 of the guiding assembly 7 in the upper guide assembly 2 and the upper guide 205, and then through the lower guide 405 in the lower guide assembly 4, forming a stable cutting path. The guide tube 702 of the guiding assembly 7 remains coaxial with the upper guide 205 and the lower guide 405, providing good guidance and correction for the electrode wire, ensuring it always moves along the correct trajectory. Simultaneously, the clamping assembly 6 continuously and stably clamps the electrode wire, ensuring its positional stability during processing.When fine adjustments to the position or angle of the electrode wire are required during processing, these adjustments can be made again via the first drive assembly 3, the second drive assembly 5, and the telescopic rod to ensure processing accuracy. After processing is complete, the first drive assembly 3 and the second drive assembly 5 are shut off, allowing the upper guide assembly 2 and the lower guide assembly 4 to return to their initial positions. The cylinder 603 is activated to release the clamping roller 601 of the clamping assembly 6, removing the electrode wire from the guide device.
