Description

Technical Field

[0001] The present application relates to the technical field of cutting equipment, and in particular to a planetary wheel wire cutting machine. Background Art

[0002] With the development of modern manufacturing, wire-cutting technology has gained widespread application in precision machining due to its high cutting speed and excellent surface quality. This technology not only increases production efficiency but also significantly improves the surface quality and dimensional accuracy of workpieces, making it a preferred process in many high-end manufacturing industries. For example, wire-cutting machines are used in the machining of planetary gears.

[0003] In wire cutting machine applications, various positioning methods are often used to secure the workpiece to ensure precise machining. Common positioning methods include fixtures, chucks, or dedicated positioning blocks. Each of these methods has its own unique characteristics. For example, fixtures are suitable for simple workpieces produced in batches, while chucks are more suitable for rapid clamping of cylindrical or conical workpieces. Positioning blocks provide more precise positioning capabilities. However, during use, manual observation of the workpiece clamping position and repeated adjustments are often required, making the operation complex and difficult to achieve accurate positioning.

[0004] Regarding the aforementioned related technologies, existing wire-cut EDM machines lack effective positioning devices when processing circular planetary gears, resulting in workpiece deviation during machining, affecting the precision and consistency of the final product. Furthermore, manually adjusting the positioning points is time-consuming and labor-intensive, reducing overall machining efficiency. Therefore, designing a wire-cut EDM capable of securing and positioning the planetary gear has become a pressing technical challenge. Summary of the Invention

[0005] In order to fix and position the planetary wheel, the present application provides a planetary wheel wire cutting machine.

[0008] The processing platform is arranged on the base, and the positioning plate is fixedly connected to the base via a mounting rod. The positioning plate is provided with a through hole along a first direction, and the processing platform is located in the through hole. There is a space between the outer peripheral wall of the processing platform and the wall of the through hole, and the processing platform is connected to the positioning plate via a plurality of support plates;

[0009] The clamping assembly is arranged on the positioning plate, and a plurality of the clamping assemblies are evenly spaced along the circumferential direction of the virtual circle, a clamping gap is formed between the plurality of the clamping assemblies, the virtual circle is located in the clamping gap, the central axis of the virtual circle is parallel to the first direction, and the processing platform is coaxially arranged with the virtual circle, the clamping assembly includes a clamping plate and an elastic member, the elastic member is arranged on a side of the clamping plate away from the clamping gap, the elastic member is connected between the positioning plate and the clamping plate, and the elastic member has a force that drives the clamping plate to move toward the side close to the clamping gap under a recoverable deformation;

[0010] The cutting assembly is arranged on the base so as to cut the workpiece.

[0011] By adopting the above technical solution, a processing platform and a cutting assembly are set up, and the workpiece to be cut is placed on the processing platform, and the cutting assembly cuts the workpiece. Since the planetary wheel is a circular plate with a toothed outer circumference, in order to improve the accuracy of cutting, it is generally necessary to place the workpiece in the center of the processing platform. To this end, a clamping assembly is set up, and multiple clamping assemblies are evenly distributed on the positioning plate along the virtual circumferential direction. Multiple clamping plates will clamp and fix the side walls of the workpiece, and when placing the workpiece, under the action of the elastic member, multiple clamping plates evenly spaced will position the workpiece to the center of the processing platform, thereby realizing the positioning and fixation of the workpiece.

[0012] Optionally, the cutting assembly includes a mounting frame, a first guide wheel, a second guide wheel and an electrode wire, the mounting frame is slidably connected to the base along a direction perpendicular to the first direction, the first guide wheel and the second guide wheel are spaced apart along the first direction, and the first guide wheel and the second guide wheel are both rotatably connected to the mounting frame, the processing platform is located between the first guide wheel and the second guide wheel, one end of the electrode wire is wound around the first guide wheel, and the other end is wound around the second guide wheel; the multiple support plates are slidably connected to the positioning plate along a direction perpendicular to the first direction.

[0013] By adopting the above technical solution, in order to cut the workpiece, a cutting assembly is set up, the electrode wire is connected to the negative pole of the pulse power supply, and the processing platform is connected to the positive pole of the power supply. The workpiece is cut by the electrode wire, and the mounting frame can slide in a direction perpendicular to the first direction to drive the electrode wire to move and cut the workpiece.

[0014] Optionally, it also includes a cylinder that drives the support plate to slide in a direction perpendicular to the first direction, a support plate is provided on both sides of the positioning plate, and a fourth sliding groove for the support plate to slide is provided on the side of the positioning plate close to the clamping gap, the cylinder housing is fixedly connected to the positioning plate, and one end of the cylinder piston rod passes through the side wall of the positioning plate and is located in the fourth sliding groove and is fixedly connected to the support plate.

[0015] By adopting the above technical solution, since the electrode wire needs to cut the workpiece in a direction perpendicular to the first direction, and the mounting frame moves to drive the electrode wire to move close to the support plate, in order not to affect the cutting of the workpiece by the electrode wire, while allowing the support plate to still support the processing platform, a sliding support plate is set. When the electrode wire slides around a support plate, a cylinder drives the support plate to slide into the fourth slide groove to make the support plate leave the cutting area, and another cylinder drives the other support plate to slide toward the side close to the processing platform so that the processing platform is supported by the other support plate.

[0016] Optionally, the clamping assembly further includes a connecting seat, which is located on a side of the clamping plate away from the clamping gap, and the elastic member is fixedly connected between the connecting seat and the clamping plate, and the connecting seat is slidably connected to the positioning plate along a direction perpendicular to the first direction.

[0017] By adopting the above technical solution, since the workpiece sizes are different, in order to increase the clamping range of the clamping plate for workpieces of different sizes, the connecting seat is slidably connected to the positioning plate along a direction perpendicular to the first direction, so that the sliding of the connecting seat drives the clamping plate to slide, thereby further expanding the clamping range of the clamping plate.

[0018] Optionally, a first sliding groove for accommodating the connecting seat is opened on one side of the positioning plate along a direction perpendicular to the first direction, one side of the connecting seat is located in the first sliding groove and slides along the wall of the first sliding groove, and the other side is located outside the first sliding groove and is connected to the clamping plate through the elastic member.

[0019] By adopting the above technical solution, in order to make the connecting seat slide, a first sliding groove is opened on the positioning plate, and the connecting seat slides in the first sliding groove and along the groove wall of the first sliding groove, thereby driving the clamping plate to slide.

[0020] Optionally, the clamping assembly also includes a first screw, which is arranged perpendicular to the first direction, one end of the first screw is located on the outside of the positioning plate, and the other end is located in another first sliding groove after passing through the side wall of the positioning plate, the first screw is rotatably connected to the positioning plate, the first screw is perpendicular to the first direction along the rotation axis of the positioning plate, and the connecting seat is provided at both ends of the first screw and slides along the length direction of the first screw.

[0021] By adopting the above technical solution, in order to drive the connecting seat to slide, the first screw is rotated, and the first screw drives the connecting seat to slide, thereby driving the clamping plate to slide.

[0022] Optionally, the positioning plate is provided with a scale groove at each of the first sliding groove openings, and when the connecting seat slides along the positioning plate, the connecting seat is located at different size marks of the scale groove.

[0023] By adopting the above technical solution, in order to further ensure that the workpiece is in the center position of the processing platform, a scale groove is set on the positioning plate, so that when the screw is rotated to drive the connecting seat to slide, personnel can use the scale groove to ensure that the sliding distance of each connecting seat is the same, thereby improving the clamping accuracy of the workpiece.

[0024] Optionally, the clamping assembly further includes a pressure plate, one end of which is located on a side of the connecting seat away from the processing platform, and the other end of which is located in the clamping gap, and the pressure plate is slidably connected to the connecting seat along a first direction.

[0025] By adopting the above technical solution, during cutting, in order to further improve the stability of the workpiece on the processing platform, a pressure plate is set, and the pressure plate is slidably connected to the connecting seat along the first direction so that the pressure plate is tightly attached to the top of the workpiece, and the workpiece is fixed by the pressure plate.

[0026] Optionally, the clamping assembly also includes a second screw, which is parallel to the first direction. One end of the second screw passes through the pressure plate and is rotated to connect to the connecting seat. The second screw is parallel to the first direction along the rotation axis of the connecting seat, and the pressure plate slides along the length of the second screw.

[0027] By adopting the above technical solution, in order to drive the pressing plate to slide, the second screw is rotated to drive the pressing plate to slide along the length direction of the second screw.

[0028] Optionally, a support member is further included, which is arranged on the bottom wall of the positioning plate, and the support member is slidably connected to the positioning plate along a direction perpendicular to the first direction.

[0029] By adopting the above technical solution, since the size of the workpiece is larger than the size of the processing platform, after the electrode wire cuts the workpiece, the cut waste may lose support and fall. During this process, the waste may contact or even hit the electrode wire, causing the electrode wire to break. For this reason, a support member is provided, and the first screw is rotated to drive the connecting seat to slide, and further drive the support member to slide, so that the support member supports the bottom wall of the workpiece to reduce the occurrence of waste falling when the workpiece is cut.

[0041] The following is combined with Figure 1-6 This application is described in further detail.

[0042] The present application discloses a planetary wheel linear cutting machine. For ease of description, this application introduces directional terms such as a first direction, a second direction, and a third direction to form a three-dimensional reference direction. The directional terms used, such as "first direction, second direction, and third direction," can be specifically illustrated with reference to the figure, where X represents the first direction X, Y represents the second direction Y, and Z represents the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0043] Reference Figure 1 and Figure 2 The planetary wheel wire cutting machine includes a base 1, a processing platform 2, a positioning plate 3, a clamping assembly 4 and a cutting assembly 5; the processing platform 2 is arranged on the base 1, and the processing platform 2 is used to support the workpiece to be processed into a planetary wheel. The positioning plate 3 is provided with a through hole 31 along the central axis direction of the virtual circle, and the positioning plate 3 is directly or indirectly fixedly connected to the base 1, the processing platform 2 is located in the through hole 31, and there is a space between the outer peripheral wall of the processing platform 2 and the hole wall of the first through hole 31 of the positioning plate 3. The processing platform 2 is connected to the positioning plate 3 through a plurality of support plates 22, and the clamping assembly 4 is provided on the positioning plate 3. There are multiple clamping assemblies 4 evenly spaced along the circumferential direction of the virtual circle, and a clamping gap 41 is formed between the multiple clamping assemblies 4. The virtual circle is located in the clamping gap 41, and the central axis of the virtual circle is parallel to the first direction, and the processing platform 2 is coaxially arranged with the virtual circle, so that the workpiece is clamped and fixed by the multiple clamping assemblies 4, and the cutting assembly 5 is provided above the processing platform 2, so that the cutting assembly 5 can cut the workpiece.

[0044] Reference Figure 2 In some embodiments, the processing platform 2 can be in the shape of a rectangular plate or a circular plate. Since the planetary wheel is a circular plate with a toothed outer periphery, the workpiece it processes is generally a square plate. In this embodiment, the processing platform 2 is a square plate, the positioning plate 3 is also a square plate, and the through hole 31 is a square hole. The center point of the processing platform 2 coincides with the center point of the through hole 31, and the virtual circle coincides with the center point of the processing platform 2. In order to improve the stability of clamping the workpiece, in this embodiment, four clamping assemblies 4 are provided, and the four clamping assemblies 4 are respectively located at the four sides of the processing platform 2 which is a square plate.

[0045] Reference Figure 1 When the cutting assembly 5 is cutting, the cutting position needs to be cooled by coolant simultaneously. In order to hold the coolant, a receiving groove 11 is opened along the first direction on the side of the base 1 close to the processing platform 2, so that the coolant can be held by the receiving groove 11.

[0046] Reference Figure 1The positioning plate 3 is fixedly connected to the base 1 through a mounting rod 32 , the mounting rod 32 is parallel to the first direction, one end of the mounting rod 32 is fixedly connected to the base 1 , and the other end is fixedly connected to the positioning plate 3 .

[0047] Reference Figure 3 In order to facilitate cutting, it is generally necessary to place the workpiece in the center of the processing platform 2 to improve the accuracy of subsequent cutting. In order to achieve precise positioning of the workpiece, the clamping assembly 4 includes a connecting seat 42, a clamping plate 43 and an elastic member 44. The connecting seat 42 is connected to the base 1, and the clamping plate 43 is arranged on the side of the connecting seat 42 close to the clamping gap 41, and the clamping plate 43 contacts the processing platform 2. The elastic member 44 is fixedly connected between the clamping plate 43 and the connecting seat 42. The elastic member 44 has a force that drives the clamping plate 43 to move toward the side close to the clamping gap 41 under recoverable deformation. In this embodiment, the elastic member 44 is a compression spring. The personnel places the workpiece on the processing platform 2. Under the action of the elastic member 44, the workpiece will be located in the center of the processing platform 2, and the clamping plate 43 will clamp and fix the workpiece, thereby achieving positioning and fixation of the workpiece.

[0048] Reference Figure 3 Since the sizes of the workpieces are different, in order to enable the clamping plate 43 to adapt to and clamp workpieces of different sizes, the connecting seat 42 is connected to the positioning plate 3 by sliding along a direction perpendicular to the first direction. The connecting seat 42 slides to drive the clamping plate 43 to slide, thereby changing the width of the clamping gap 41 to achieve clamping and fixing of different workpieces.

[0049] Reference Figure 3 In order to make the connecting seat 42 slide, a first sliding groove 21 for accommodating the connecting seat 42 is opened on one side of the processing platform 2 along a direction perpendicular to the first direction. One side of the connecting seat 42 is located in the first sliding groove 21 and slides along the groove wall of the first sliding groove 21, and the other side extends to the outside of the first sliding groove 21. The connecting seat 42 slides in the first sliding groove 21 and drives the clamping plate 43 to slide along the direction perpendicular to the first direction.

[0050] Reference Figure 3 In order to drive the connecting seat 42 to slide, the clamping assembly 4 also includes a first screw 45. In this embodiment, four first screws 45 are provided. The first screws 45 are arranged corresponding to the first slide groove 21. The first screw 45 is arranged perpendicular to the first direction. One end of the first screw 45 is located on the outside of the positioning plate 3, and the other end is located in another first slide groove 21 after passing through the side wall of the positioning plate 3. The first screw 45 is rotatably connected to the positioning plate 3. The first screw 45 is perpendicular to the first direction along the rotation axis of the positioning plate 3. The connecting seat 42 is sleeved on the first screw 45 and slides along the length direction of the first screw 45. Rotating the first screw 45 drives the connecting seat 42 to slide, thereby driving the clamping plates 43 to move closer or farther away from each other.

[0051] Reference Figure 3, each first screw 45 rotates to drive the two connecting seats 42 to slide, and drives the two clamping plates 43 to slide. During this process, in order to ensure that the workpiece can still be located in the center of the processing platform 2, the four clamping plates 43 need to slide the same distance. To this end, the positioning plate 3 is provided with a scale groove 33 at the notch of each first slide groove 21. During the sliding process of the connecting seat 42 along the positioning plate 3, the connecting seat 42 is located at different size marks of the scale groove 33. When the personnel rotates the screw to drive the connecting seat 42 to slide, they can see the sliding distance of the connecting seat 42 through the scale groove 33 on the positioning plate 3, which is convenient for the personnel to slide the four connecting seats 42 the same distance.

[0052] Reference Figure 1 and Figure 4 The cutting assembly 5 includes a mounting frame 51, a first guide wheel 52, a second guide wheel 53 and an electrode wire 54. The mounting frame 51 is slidably connected to the base 1 along a direction perpendicular to the first direction. The first guide wheel 52 and the second guide wheel 53 are spaced apart along the first direction, and the first guide wheel 52 and the second guide wheel 53 are both rotatably connected to the mounting frame 51. The first guide wheel 52 and the second guide wheel 53 are parallel to the second direction along the rotation axis of the mounting frame 51. The processing platform 2 is located between the first guide wheel 52 and the second guide wheel 53. One end of the electrode wire 54 is wound around the first guide wheel 52, and the other end is wound around the second guide wheel 53.

[0053] Reference Figure 4 In order to drive the first guide wheel 52 and the second guide wheel 53 to rotate, the cutting assembly 5 also includes a motor 55. The first guide wheel 52 is connected to the mounting frame 51 through a first fixed seat 521, and the second guide wheel 53 is connected to the mounting frame 51 through a second fixed seat 531. A motor 55 is installed on the first fixed seat 521 and the second fixed seat 531. One output shaft of one motor 55 is coaxially fixedly connected to the first guide wheel 52, and the other output shaft of the other motor 55 is coaxially fixedly connected to the second guide wheel 53, so that the motor 55 drives the first guide wheel 52 and the second guide wheel 53 to rotate.

[0054] Reference Figure 4, the mounting frame 51 is connected to the base 1 for sliding along a direction perpendicular to the first direction. Specifically, the mounting frame 51 slides along the second direction, and the mounting frame 51 slides along the third direction. The third direction is perpendicular to both the first direction and the second direction. In order to drive the mounting frame 51 to slide, the planetary wheel wire cutting machine also includes a sliding assembly 6, which includes a first slide rail 61 and a second slide rail 62. The first slide rail 61 is parallel to the second direction. The bottom wall of the mounting frame 51 is fixedly connected to a first slider 511. A second slide groove 611 for sliding the first slider 511 is opened on one side of the first slide rail 61 along the second direction. The second slide rail 62 is parallel to the third direction and fixedly connected to the base 1. The bottom wall of the first slide rail 61 is fixedly connected to a second slider 612. A third slide groove 621 for sliding the second slider 612 is opened on one side of the second slide rail 62 along the third direction. By driving the first slider 511 to slide in the second slide groove 611, the electrode wire 54 is driven to slide in the second direction, and the second slider 612 is driven to slide in the third slide groove 621 to drive the electrode wire 54 to slide in the third direction.

[0055] The cutting assembly 5 is the existing technology in this field. When in use, the electrode wire 54 is connected to the negative pole of the pulse power supply, and the processing platform 2 is connected to the positive pole of the power supply. The workpiece is cut by the electrode wire 54. The sliding of the first slider 511 and the second slider 612 can be achieved by a driving device such as the cylinder 7, which will not be elaborated here.

[0056] Reference Figure 5 , support plates 22 are provided on both sides of the positioning plate 3, and the processing platform 2 is supported by the support plates 22. Since the planetary wheel is a ring structure, the cutting assembly 5 needs to slide in the horizontal direction to cut the workpiece during processing. In order to enable the positioning plate 3 to support the processing platform 2 while not blocking the cutting assembly 5 from cutting the workpiece, the support plate 22 is slidably connected to the positioning plate 3 in a direction perpendicular to the first direction. Specifically, a fourth sliding groove 34 for sliding the support plate 22 is opened on one side of the positioning plate 3 close to the clamping gap 41 along the second direction. The second direction is perpendicular to the first direction. The support plate 22 is located in the fourth sliding groove 34 and slides along the groove wall of the fourth sliding groove 34;

[0057] Reference Figure 5 In order to drive the support plate 22 to slide, the planetary wheel linear cutting machine includes a cylinder 7, the cylinder shell of the cylinder 7 is fixedly connected to the positioning plate 3, the piston rod of the cylinder 7 passes through the side wall of the positioning plate 3 and is located in the fourth slide groove 34, and is fixedly connected to the side wall of the support plate 22, and the support plate 22 is driven by the cylinder 7 to slide in the second direction. When the cutting assembly 5 slides around a support plate 22, the cylinder 7 drives the support plate 22 to slide in the direction of the fourth slide groove 34, so that the support plate 22 leaves the cutting area, and the remaining cylinders 7 drive the remaining support plates 22 to slide toward the side close to the processing platform 2, so as to drive the remaining support plates 22 to support the processing platform 2.

[0058] It should be noted that during processing, the electrode wire 54 needs to pass through the workpiece for cutting, so the outer dimension of the workpiece needs to be larger than the outer dimension of the processing platform 2.

[0059] Reference Figure 5 and Figure 6 , because the size of the workpiece is larger than the size of the processing platform 2, after the electrode wire 54 cuts the workpiece, the cut waste may lose support and fall. During this process, the waste may contact or even hit the electrode wire 54, causing the electrode wire 54 to break. For this reason, the planetary wheel wire cutting machine also includes a support member 8, which is located below the positioning plate 3. The support member 8 includes a horizontal portion 81 and a vertical portion 82 fixedly connected to each other. A fifth slide groove 35 is provided on one side of the positioning plate 3 close to the first clamping gap 41 for the horizontal portion 81 to slide along a first direction perpendicular to the first direction. The fifth slide groove 35 is connected to the first slide groove 21. One end of the horizontal portion 81 passes through the fifth slide groove 35 and is fixedly connected to the connecting seat 42, and the other end is fixedly connected to the vertical portion 82. The end wall of the vertical portion 82 away from the horizontal portion 81 is flush with the bottom wall of the processing platform 2, so that the bottom of the workpiece is supported by multiple vertical portions 82, thereby reducing the occurrence of waste falling during workpiece cutting.

[0060] Reference Figure 6 In order to further improve the stability of the workpiece placed on the processing platform 2, the clamping assembly 4 also includes a pressure plate 46, one end of the pressure plate 46 is arranged on the side of the connecting seat 42 away from the processing platform 2, and the other end is located in the first clamping gap 41, so that the pressure plate 46 can press the top of the workpiece, thereby improving the stability of the workpiece fixation. Since the heights of the workpieces are different, the pressure plate 46 is slidably connected to the clamping plate 43 along the center axis direction of the virtual circle, so that the pressure plate 46 can press workpieces of different heights.

[0061] Reference Figure 6 In order to drive the pressure plate 46 to slide, the clamping assembly 4 also includes a second screw 47. The second screw 47 is parallel to the central axis of the virtual circle. One end of the second screw 47 passes through the pressure plate 46 and is rotated and connected to the connecting seat 42. The second screw 47 is parallel to the central axis of the virtual circle along the rotation axis of the connecting seat 42. The pressure plate 46 slides along the length of the second screw 47. When a person rotates the second screw 47, the pressure plate 46 slides along the length of the second screw 47.

[0062] Reference Figure 6In order to guide the sliding of the pressure plate 46 along the length direction of the second screw 47, the clamping assembly 4 also includes a guide rod 48. The guide rod 48 is parallel to the second screw 47. One end of the guide rod 48 passes through the pressure plate 46 and is fixedly connected to the connecting seat 42. The pressure plate 46 slides along the length direction of the guide rod 48. The guide rod 48 and the second screw 47 are connected by a limit plate 49. The limit plate 49 is fixedly connected to the end of the guide rod 48. The second screw 47 is passed through the limit plate 49 so that the guide rod 48 can guide the sliding of the pressure plate 46.

[0063] It should be noted that, during processing, the pressing plate 46 and the vertical portion 82 both avoid the cutting position of the electrode wire 54 on the workpiece.

[0064] The implementation principle of the planetary wheel wire cutting machine of the embodiment of the present application is as follows: during processing, the operator measures the size of the workpiece to be processed, adjusts the position of the first clamping seat according to the size, rotates the first screw 45 to drive the connecting seat 42 to slide, and ensures that the four first clamping seats move to the same position relative to the processing platform 2 according to the scale groove 33, places the workpiece on the processing platform 2, and clamps and positions the workpiece by the clamping plate 43, rotates the first screw 45, and at the same time drives the support member 8 to slide along the length direction of the first screw 45, so that the bottom of the workpiece is supported by the vertical portion 82, and the second screw 47 is rotated to drive the pressing plate 46 to press and fix the workpiece;

[0065] When the electrode wire 54 is cutting, when the electrode wire 54 slides around a support plate 22, the cylinder 7 drives the support plate 22 to slide in the direction of the fourth slide groove 34 to make the support plate 22 leave the cutting area, and the remaining cylinders 7 drive the remaining support plates 22 to slide toward the side close to the processing platform 2 to drive the remaining support plates 22 to support the processing platform 2, that is, according to the position of the movement of the cutting component 5, the position of the support plate 22 is adaptively adjusted so that no matter where the electrode wire 54 cuts the workpiece, the support plate 22 can support the processing platform 2.

[0066] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
