Description

Technical Field

[0001] This invention belongs to the field of laser cutting equipment technology, specifically a laser cutting device for irregularly shaped hardware parts. Background Technology

[0002] Laser cutting utilizes a high-energy-density laser beam to heat the workpiece, causing the temperature to rise rapidly and reach the material's boiling point in a very short time. The material then begins to vaporize, forming steam. This steam is ejected at high speeds, creating cuts in the material simultaneously. With the continuous development of cutting technology, more and more industries and companies are using laser cutting.

[0003] A laser cutting device for irregularly shaped hardware (CN110142521B) uses a positioning and locking mechanism to tighten and lock the inner wall of the irregularly shaped hardware from its inner cavity outwards. This mechanism automatically adjusts the shape of the outer wall according to the shape of the inner cavity. Equipped with a laser cutting component, it can cut irregularly shaped hardware, increasing work efficiency. During clamping and positioning, the radial locking mechanism uniformly tightens and positions the inner wall of the irregularly shaped hardware, while the axial locking mechanism locks and positions the irregularly shaped hardware in the axial direction, effectively ensuring the positioning effect.

[0004] In the aforementioned publicly available document, although a water-filled bladder is used for shape-fitting and clamping, the applicable shapes of the hardware are limited. It is only applicable to hardware with a conical structure and not to hardware with a square structure. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a laser cutting device for irregularly shaped hardware parts.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a laser cutting device for irregularly shaped hardware parts, comprising a sliding seat, a moving component, a mounting seat, a position adjusting component, and a laser cutting head. The laser cutting head is mounted on the mounting seat via the position adjusting component, which is used to drive the laser cutting head to move in the x, y, and z directions. The moving component is connected to the sliding seat, which is disposed on both sides of the laser cutting head. The moving component is used to drive the sliding seats on both sides to move and clamp and fix the hardware parts. The device also includes a driving component, which is mounted on the sliding seat. The output ends of the driving component on both sides are movably connected to baffles. A first internal tube and a second internal tube are respectively connected to the baffles on both sides. A plurality of rotating rods are rotatably mounted on both sides of the first internal tube and the second internal tube. The tilt direction of the rotating rods on the first internal tube and the second internal tube is towards the corresponding sliding seat. A second spring is connected between the rotating rod and the first internal tube or the second internal tube. A connecting rope is connected between the rotating rods on both sides, and the plurality of connecting ropes are connected by a main rope.

[0007] As a further improvement: the moving component includes a fixed base, a telescopic component, and a track. The telescopic component is mounted on the fixed base, and the output end of the telescopic component is connected to the sliding base. The sliding base is mounted on the track and is slidably connected to the track.

[0008] As a further improvement: several triangular protrusions are installed on the track, which are slidably connected to the sliding seat. The triangular protrusions are provided with chip collection grooves on both sides.

[0009] As a further improvement: the output end of the drive component is connected to a ring shaft, and a transmission component is connected to the ring shaft. The end of the transmission component away from the ring shaft is connected to the baffle. A winding shaft is fixedly installed on the ring shaft and is connected to the main rope. The transmission component is used to drive the first internal tube, the second internal tube, and the winding shaft to rotate synchronously when the drive component rotates forward, and to drive the first internal tube, the second internal tube, and the winding shaft to rotate relative to each other when the drive component rotates in reverse.

[0010] As a further improvement: a sleeve is installed at the end of the first internal tube near the second internal tube, and a moving rod is installed at the end of the second internal tube near the first internal tube. A moving groove corresponding to the moving rod is opened in the sleeve.

[0011] As a further improvement: the transmission assembly includes a fixed plate, a movable plate, and a first spring. Several fixed plates are fixedly installed circumferentially on the ring shaft. A movable plate is rotatably installed at one end of the fixed plate. A first spring is installed between the movable plate and the fixed plate. An annular groove is formed on the baffle. Several trapezoidal grooves are formed on the outer side of the annular groove. The trapezoidal grooves communicate with the annular groove. The fixed plate is located in the annular groove, and the movable plate is located in the trapezoidal groove.

[0012] As a further improvement, a flexible plate is provided on the side of the baffle near the first or second internal tube.

[0013] As a further improvement: a flexible column is installed at the end of the rotating rod away from the first or second internal tube.

[0014] As a further improvement, it also includes a support frame and rollers. An extension support is fixedly installed on one side of the sliding seat, and several support frames are slidably installed on the extension support. A third spring connects the extension support and the support frames, and a roller is rotatably installed on one end of the support frame.

[0015] As a further improvement: a fixing strip is installed on one side of the support frame, and a cleaning component is installed on one end of the fixing strip near the first or second internal tube. The fixing strips on the two sliding seats are respectively placed on both sides of the support frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are: by setting rotating rods on both sides of the first and second internal tubes, it can adapt to flat tubes and other long strip structures of any irregular shape, as long as there is a symmetrical structure. The presence of a symmetrical structure allows the rotating rods to clamp the inner wall of the hardware. In addition, the driving action of the driving component allows the hardware to be cut. After being cut, the hardware is still locked on the first and second internal tubes, so that the next cutting process can be carried out. Attached Figure Description

[0029] The technical solution of this application will be further described in detail below with reference to specific embodiments.

[0030] The embodiments of this application are described in detail below. Examples of these 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.

[0031] Please see Figures 1 to 11 In one embodiment, a laser cutting device for irregularly shaped hardware includes a sliding base 1, a moving component 3, a mounting base 2, a position adjusting component 5, and a laser cutting head 4. The laser cutting head 4 is mounted on the mounting base 2 via the position adjusting component 5. The position adjusting component 5 is used to drive the laser cutting head 4 to move in the x, y, and z directions. By driving the laser cutting head 4 in three directions through the position adjusting component 5, it is possible to cut special patterns on the surface of the hardware, such as drilling holes on the surface of a trolley case rod using laser cutting. The moving component 3 is connected to the sliding base 1, and the sliding base 1 is disposed on both sides of the laser cutting head 4. The moving component 3 is used to drive the sliding bases 1 on both sides. The device for clamping and fixing the hardware also includes a drive component 23, which is mounted on a sliding seat 1. Both sides of the drive component 23 are movably connected to baffles 9. A first internal tube 11 and a second internal tube 13 are respectively connected to the baffles 9 on both sides. Several rotating rods 15 are rotatably mounted on both sides of the first internal tube 11 and the second internal tube 13. The tilt direction of the rotating rods 15 on the first internal tube 11 and the second internal tube 13 is towards the corresponding sliding seat 1. A second spring 16 is connected between the rotating rod 15 and the first internal tube 11 or the second internal tube 13. A connecting rope 6 is connected between the rotating rods 15 on both sides. Several connecting ropes 6 are connected by a main rope 25.

[0032] In this embodiment, the irregular-shaped hardware refers to long, hollow hardware that is symmetrical on both sides, such as a luggage handle. The handle hardware is hollow and has a cross-section that is close to a rectangle, with one pair of opposite sides using rounded corners or other pleated forms. For example, a flat tube is generally clamped at both ends when it is cut. However, once it is cut, the clamping state is instantly released, making it impossible to continue cutting, thus causing the clamping operation to be repeated.

[0033] The drive component 23 can be driven to rotate by a stepper motor or a servo motor, and the winding of the main rope 25 can be carried out by a separate motor.

[0034] In this embodiment, during cutting, the position of the sliding seats 1 on both sides is first adjusted by the moving component 3, thereby placing the hardware between the sliding seats 1 on both sides. One end of the hardware is then fitted onto the outside of the rotating rod 15 from one end of the first built-in tube 11. Figure 8Viewed from the center, the hardware is fitted onto the outside of the first internal tube 11 from right to left. During the fitting process, the rotating rod 15 is squeezed to rotate, and one end of the rotating rod 15 moves relative to the inner wall of the hardware. When one end of the hardware reaches the baffle 9, the rotating rod 15 is fully extended and completely fixed. Through the obliquely arranged rotating rod 15, the hardware is locked at this time. During the fitting process, the hardware can only move from right to left and cannot move in the opposite direction. When the hardware moves to the baffle 9, both ends of the hardware are locked. At this time, by moving the sliding seat 1 through the moving component 3, the second internal tube 13 actively fits onto the hardware until the other end of the hardware is close to the baffle 9. At this time, the clamping of the hardware is completed. In this invention, by setting the rotating rods 15 on both sides of the first internal tube 11 and the second internal tube 13, it can adapt to flat tubes and... Other irregularly shaped long strip structures are acceptable, as long as they have a symmetrical structure. The symmetrical structure allows the rotating rod 15 to clamp the inner wall of the hardware. After clamping, the position adjustment component 5 is activated to adjust the position of the laser cutting head 4, thereby completing the cutting of the pattern shape on the surface of the hardware. In addition, the driving component 23 can drive the hardware to cut. Even after cutting, the hardware divided into two parts remains locked on the first internal tube 11 and the second internal tube 13, so that the next cutting process can continue. After cutting, the sliding seats 1 on both sides are moved away by the moving component 3, and then the main rope 25 is wound around. After winding, the rotating rod 15 releases the clamping of the inner wall of the hardware. At this time, the cut hardware can be taken out.

[0035] By setting rotating rods 15 on both sides of the first internal tube 11 and the second internal tube 13, it can adapt to flat tubes and other long strip structures of any irregular shape, as long as there is a symmetrical structure. The existence of the symmetrical structure allows the rotating rods 15 to clamp the inner wall of the hardware. In addition, the hardware can be cut by the driving action of the driving component 23. After being cut, the hardware is still locked on the first internal tube 11 and the second internal tube 13, so that the next cutting process can be carried out.

[0036] Please see Figure 1 , Figure 2 In one embodiment, the moving component 3 includes a fixed base 31, a telescopic member 32, and a track 33. The telescopic member 32 is mounted on the fixed base 31, and the output end of the telescopic member 32 is connected to the sliding base 1. The sliding base 1 is mounted on the track 33 and is slidably connected to the track 33.

[0037] In this embodiment, the fixed seat 31 is located outside the track 33, and the position movement of the sliding seat 1 is achieved by the extension and retraction of the telescopic member 32. The telescopic member 32 can be a hydraulic telescopic member 32 or an electric telescopic rod, and the specific implementation is not limited.

[0038] The moving component 3 can also use a bidirectional lead screw to move the positions of the two sliding seats 1, and is not limited to the form of the telescopic component 32 mentioned above.

[0039] Please see Figure 2 In one embodiment, a plurality of triangular protrusions 331 are installed on the track 33, and are slidably connected to the sliding seat 1 through the triangular protrusions 331. Chip collection grooves 332 are provided on both sides of the triangular protrusions 331.

[0040] In this embodiment, by providing a triangular protrusion 331 on the track 33, the sliding position of the sliding seat 1 can be moved by the triangular protrusion 331. At the same time, the triangular structure of the triangular protrusion 331 can guide the debris generated during the laser cutting process to the chip collection groove 332, so as to avoid the debris covering the triangular protrusion 331 and thus affecting the movement of the sliding seat 1.

[0041] Please see Figure 10 In one embodiment, the output end of the drive member 23 is connected to a ring shaft 7, and a transmission assembly 8 is connected to the ring shaft 7. The end of the transmission assembly 8 away from the ring shaft 7 is connected to the baffle 9. A winding shaft 24 is fixedly installed on the ring shaft 7. The winding shaft 24 is connected to the main rope 25. The transmission assembly 8 is used to drive the first internal tube 11, the second internal tube 13 and the winding shaft 24 to rotate synchronously when the drive member 23 rotates forward, and to drive the first internal tube 11, the second internal tube 13 and the winding shaft 24 to rotate relative to each other when the drive member 23 rotates in reverse.

[0042] In this embodiment, during cutting, the position of the two sliding seats 1 is first adjusted by the moving component 3, thereby placing the hardware between the two sliding seats 1. One end of the hardware is then fitted onto the outside of the rotating rod 15 from one end of the first built-in tube 11. Figure 8Viewed from the center, the hardware is fitted onto the outside of the first internal tube 11 from right to left. During the fitting process, the rotating rod 15 is squeezed to rotate, and one end of the rotating rod 15 moves relative to the inner wall of the hardware. When one end of the hardware reaches the baffle 9, the rotating rod 15 is fully extended and completely fixed. Through the obliquely arranged rotating rod 15, the hardware is locked at this time. During the fitting process, the hardware can only move from right to left and cannot move in the opposite direction. When the hardware moves to the baffle 9, both ends of the hardware are locked. At this time, by moving the sliding seat 1 through the moving component 3, the second internal tube 13 actively fits onto the hardware until the other end of the hardware is pressed against the baffle 9. At this time, the clamping of the hardware is completed. In this invention, by setting the rotating rods 15 on both sides of the first internal tube 11 and the second internal tube 13, it can adapt to flat tubes and other long strip structures of any irregular shape, as long as there is a symmetrical structure. The symmetrical structure allows the rotating rod 15 to clamp the inner wall of the hardware. After clamping, the position adjustment component 5 is used to adjust the position of the laser cutting head 4, thereby enabling the cutting of the surface pattern of the hardware. In addition, when the drive component 23 rotates forward, the transmission component 8 drives the first internal tube 11, the second internal tube 13, and the winding shaft 24 to rotate synchronously, which can cut the hardware. After cutting, the moving component 3 is used to move the sliding seats 1 on both sides away, and then the drive component 23 is started, causing the drive component 23 to rotate in reverse, which drives the first internal tube 11, the second internal tube 13, and the winding shaft 24 to rotate relative to each other through the transmission component 8. That is, the winding shaft 24 rotates, while the first internal tube 11 and the second internal tube 13 remain stationary, so that the main rope 25 can be wound. After winding, the rotating rod 15 releases the clamping force on the inner wall of the hardware, and the cut hardware can be taken out.

[0043] Please see Figure 7 , Figure 11 In one embodiment, a sleeve 12 is installed at one end of the first built-in tube 11 near the second built-in tube 13, and a moving rod 14 is installed at one end of the second built-in tube 13 near the first built-in tube 11. A moving groove 121 corresponding to the moving rod 14 is opened in the sleeve 12.

[0044] In this embodiment, during cutting, the position of the two sliding seats 1 is first adjusted by the moving component 3, thereby placing the hardware between the two sliding seats 1. One end of the hardware is then fitted onto the outside of the rotating rod 15 from one end of the first built-in tube 11. Figure 8Viewed from the center, it fits onto the outside of the first internal tube 11 from right to left. During the fitting process, it can compress the rotating rod 15 to rotate, and one end of the rotating rod 15 moves relative to the inner wall of the hardware. When one end of the hardware reaches the baffle 9, the rotating rod 15 is fully extended and completely fixed. Through the obliquely arranged rotating rod 15, the hardware is locked at this time. During the fitting process, the hardware can only move from right to left and cannot move in the opposite direction. When the hardware moves to the baffle 9, both ends of the hardware are locked. At this time, the sliding seat 1 is moved by the moving component 3, even if... The second internal tube 13 actively engages with the hardware component. During the engagement process, the moving rod 14 inserts into the moving slot 121, causing the first internal tube 11 and the second internal tube 13 to form a whole until the other end of the hardware component is tightly pressed against the baffle 9. At this point, the hardware component is clamped. The moving rod 14 and the sleeve 121 ensure stability when the first internal tube 11 and the second internal tube 13 rotate. Furthermore, after cutting the hardware component, it can be evenly locked, preventing gaps in the middle that could cause the hardware component to fall off after cutting. Additionally, after cutting the hardware component, a gap is left... When making the cut, the sliding seats 1 on both sides move closer together via the moving component 3, allowing the cut hardware to be reassembled, thereby improving the overall stability of the hardware. In this invention, by setting rotating rods 15 on both sides of the first internal tube 11 and the second internal tube 13, it can adapt to flat tubes and other irregularly shaped long structures, as long as a symmetrical structure exists. The symmetrical structure allows the rotating rods 15 to clamp the inner wall of the hardware. After clamping, the position adjustment component 5 is activated to adjust the position of the laser cutting head 4. The section allows for the cutting of the surface pattern shape of the hardware. In addition, the driving component 23 can be used to cut the hardware. Even after cutting, the hardware is still locked on the first internal tube 11 and the second internal tube 13, so that the next cutting process can continue. After cutting, the sliding seats 1 on both sides are moved away by the moving component 3, and then the main rope 25 is wound around. After winding, the rotating rod 15 releases the pressure on the inner wall of the hardware. At this time, the cut hardware can be taken out.

[0045] Please see Figure 9 , Figure 10In one embodiment, the transmission assembly 8 includes a fixed plate 81, a movable plate 83, and a first spring 82. A plurality of fixed plates 81 are fixedly mounted on the annular shaft 7 in a circumferential direction. A movable plate 83 is rotatably mounted on one end of the fixed plate 81. A first spring 82 is installed between the movable plate 83 and the fixed plate 81. An annular groove 91 is provided on the baffle 9. A plurality of trapezoidal grooves 92 are provided on the outer side of the annular groove 91. The trapezoidal grooves 92 communicate with the annular groove 91. The fixed plate 81 is located in the annular groove 91, and the movable plate 83 is located in the trapezoidal grooves 92.

[0046] In this embodiment, a support plate 84 is installed on the side of the fixed plate 81 and the movable plate 83 that rotate relative to each other. A first spring 82 is connected between the support plates 84. The rotation angle range of the movable plate 83 relative to the fixed plate 81 is 0-90 degrees. When the movable plate 83 and the fixed plate 81 are on the same plane, the movable plate 83 is located at the right angle side of the trapezoidal groove 92. At this time, when the ring shaft 7 rotates, it can drive the baffle 9 to rotate through the movable plate 83. When the ring shaft 7 rotates in the opposite direction, under the pushing action of the side of the trapezoidal groove 92, the movable plate 83 rotates, causing the movable plate 83 to rotate 90 degrees, so that the movable plate 83 and the fixed plate 81 are both located in the ring groove 91. At this time, when the ring shaft 7 rotates, the baffle 9 remains stationary, which can drive the winding shaft 24 to rotate. Through relative rotation, the main rope 25 can be wound, so that the rotating rods 15 on both sides move closer to each other, so that they are released from the locking state, and the position of the hardware can be adjusted or the hardware can be removed.

[0047] The transmission component 8 can also be implemented by means of a telescopic rod, which extends into the trapezoidal groove 92 to achieve synchronous rotation, and can achieve relative rotation when the telescopic rod is retracted.

[0048] Please see Figures 7 to 11 In one embodiment, a flexible plate 10 is provided on the side of the baffle 9 near the first built-in tube 11 or the second built-in tube 13.

[0049] In this embodiment, by providing a flexible plate 10, the friction between the baffle 9 and the hardware can be increased when clamping the irregular hardware, thereby ensuring that the hardware is stably clamped between the baffle 9. Secondly, when cutting the cross section of the hardware, it can also prevent the hardware from slipping when the clamping force suddenly disappears after cutting, and at the same time, it can also prevent wear on the end of the hardware, so as not to affect the subsequent insertion and connection of the hardware.

[0050] Please see Figure 10 In one embodiment, a flexible column 151 is installed at the end of the rotating rod 15 away from the first built-in tube 11 or the second built-in tube 13.

[0051] In this embodiment, by providing a flexible column 151 at the end of the rotating rod 15, the friction between the rotating rod 15 and the inner wall of the hardware can be increased by the flexible column 151 when the rotating rod 15 is pressed against the inner wall of the hardware, and at the same time, the wear caused to the inner wall of the hardware by the pressing of the rotating rod 15 can be avoided.

[0052] Please see Figure 5 , Figure 6 In one embodiment, the system further includes a support frame 17 and a roller 18. An extension support 21 is fixedly installed on one side of the sliding seat 1. A plurality of support frames 17 are slidably installed on the extension support 21. A third spring 22 is connected between the extension support 21 and the support frame 17. A roller 18 is rotatably installed on one end of the support frame 17.

[0053] In this embodiment, by providing a support frame 17 with elastic connection, the rollers 18 on the support frame 17 can support the hardware while driving the hardware to rotate, and the support frame 17 will move up and down as the hardware rotates.

[0054] Please see Figure 5 , Figure 6 In one embodiment, a fixing strip 19 is installed on one side of the support frame 17, and a cleaning component 20 is installed on one end of the fixing strip 19 near the first internal tube 11 or the second internal tube 13. The fixing strips 19 on the two sliding seats 1 are respectively placed on both sides of the support frame 17.

[0055] In this embodiment, by setting up cleaning components 20 on both sides, the debris scattered on the surface of the hardware can be cleaned while the hardware rotates, thus avoiding affecting the laser cutting effect.

[0056] The working process of this invention is as follows: During cutting, the position of the sliding seats 1 on both sides is first adjusted by the moving component 3, thereby placing the hardware between the sliding seats 1 on both sides. One end of the hardware is then sleeved onto the outside of the rotating rod 15 from one end of the first built-in tube 11. Figure 8Viewed from the inside, the hardware is fitted onto the outside of the first internal tube 11 from right to left. During the fitting process, the rotating rod 15 is squeezed to rotate, and one end of the rotating rod 15 moves relative to the inner wall of the hardware. When one end of the hardware reaches the baffle 9, the rotating rod 15 is fully extended and completely fixed. Through the obliquely arranged rotating rod 15, the hardware is locked at this time. During the fitting process, the hardware can only move from right to left and cannot move in the opposite direction. When the hardware moves to the baffle 9, both ends of the hardware are locked. At this time, the sliding seat 1 is moved by the moving component 3, so that the second internal tube 13 actively fits onto the hardware until the other end of the hardware is close to the baffle 9. During the fitting process, the moving rod 14 will be inserted into the moving groove 121, so that the first internal tube 11 and the second internal tube 13 form a whole until the other end of the hardware is close to the baffle 9. At this time, the hardware is clamped. 12 can remain stable when the first built-in tube 11 and the second built-in tube 13 rotate. After clamping, the position of the laser cutting head 4 is adjusted by activating the position adjustment component 5, so as to complete the cutting of the surface pattern shape of the hardware. In addition, when the movable plate 83 and the fixed plate 81 are on the same plane, the movable plate 83 is located at the right angle side of the trapezoidal groove 92. At this time, when the ring shaft 7 rotates, the movable plate 83 can drive the baffle 9 to rotate. When the ring shaft 7 rotates in the opposite direction, the movable plate 83 rotates under the pushing action of the side of the trapezoidal groove 92, so that the movable plate 83 rotates 90 degrees, so that the movable plate 83 and the fixed plate 81 are both located in the ring groove 91. At this time, when the ring shaft 7 rotates, the baffle 9 remains stationary, which can drive the winding shaft 24 to rotate. Through relative rotation, the main rope 25 can be wound, so that the rotating rods 15 on both sides are brought closer to each other, so that the locking state is released, and the position of the hardware can be adjusted or the hardware can be removed.

[0057] The cleaning component 20 can be a brush or a silicone scraper, and the structure of the cleaning component 20 is not limited to the above two forms.

[0058] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0059] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
