DETAILED DESCRIPTION

[0029] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods.

[0030] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0031] See also Figures 1 to 11 In one embodiment, a laser cutting device for special-shaped hardware includes a sliding seat 1, a moving component 3, a mounting seat 2, a position adjustment component 5 and a laser cutting head 4. The laser cutting head 4 is installed on the mounting seat 2 through the position adjustment component 5. The position adjustment component 5 is used to drive the laser cutting head 4 to move in the x, y and z directions. The laser cutting head 4 is driven in three directions by the position adjustment component 5, so that special patterns can be cut on the surface of the hardware, such as drilling holes on the surface of the trolley case rod body by laser cutting. The moving component 3 is connected to the sliding seat 1, and the sliding seat 1 is arranged on both sides of the laser cutting head 4. The moving component 3 is used to drive the sliding seats on both sides. The movable seat 1 moves to clamp and fix the hardware, and also includes a driving member 23, which is installed on the sliding seat 1. The output ends of the driving member 23 on both sides are movably connected with baffles 9, and the baffles 9 on both sides are respectively connected with the first built-in tube 11 and the second built-in tube 13. A plurality of rotating columns are rotatably installed on both sides of the first built-in tube 11 and the second built-in tube 13. The inclination direction of the rotating columns on the first built-in tube 11 and the second built-in tube 13 is toward the corresponding sliding seat 1. A second spring 16 is connected between the rotating column and the first built-in tube 11 or the second built-in tube 13. A connecting rope 6 is connected between the rotating columns on both sides, and the plurality of connecting ropes 6 are connected by a main rope 25.

[0032] In this embodiment, the special-shaped hardware is aimed at long hollow hardware with symmetry on both sides, such as the pull rod used in a suitcase. The pull rod hardware is a hollow structure with a cross-section close to a rectangle, and one set of opposite sides is in the form of rounded corners or other wrinkles; for example, a flat tube, when cutting, generally adopts the form of clamping at both ends, but when it is cut, the clamping state is instantly released, and further cutting cannot be performed, resulting in repeated clamping operations.

[0033] The driving member 23 can be driven to rotate by a stepping motor or a servo motor, and the main rope 25 can be wound by a single motor.

[0034] In this embodiment, when cutting, the positions of the two side sliding seats 1 are adjusted by moving the assembly 3, so that the hardware is placed between the two side sliding seats 1, and one end of the hardware is put on the outer side of the rotating rod 15 from one end of the first inner tube 11. Figure 8As can be seen in the figure, it is sleeved on the outside of the first built-in tube 11 from right to left. During the sleeve connection process, the rotating rod 15 can be 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 has been completely fixed. The hardware is locked at this time by the obliquely arranged rotating rod 15. During the sleeve connection process, the hardware can only move from right to left, but 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 built-in tube 13 actively sleeves the hardware until the other end of the hardware is tightly attached to the baffle 9. At this time, the clamping of the hardware is completed. The present invention is adapted to the flat tube by arranging the rotating rods 15 on both sides of the first built-in tube 11 and the second built-in tube 13. And any other irregular shaped strip structures, as long as there is a symmetrical structure, the symmetrical structure can be used to clamp the inner wall of the hardware by the rotating rod 15. After the clamping is completed, the position of the laser cutting head 4 is adjusted by starting the position adjustment component 5, so that the cutting of the surface pattern of the hardware can be completed. In addition, the hardware can be cut by the driving cooperation of the driving member 23. Even if the cutting process is performed in the present invention, the hardware divided into two parts is still locked on the first built-in tube 11 and the second built-in tube 13, so that the next cutting process can be continued. When the cutting is completed, the sliding seats 1 on both sides are first moved away by the moving component 3, and then the main rope 25 is wound. After winding, the rotating rod 15 cancels the tightness on the inner wall of the hardware. At this time, the cut hardware can be taken out.

[0035] By arranging the rotating rod 15 on both sides of the first built-in tube 11 and the second built-in 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 inner wall of the hardware can be clamped by the rotating rod 15 through the existence of the symmetrical structure; in addition, the hardware can be cut through the driving cooperation of the driving member 23, and the hardware divided into two parts after cutting still remains locked on the first built-in tube 11 and the second built-in tube 13, so that the next cutting process can be continued.

[0036] See also Figure 1 , Figure 2 In one embodiment, the moving component 3 includes a fixed seat 31, a telescopic member 32 and a track 33. The telescopic member 32 is installed on the fixed seat 31, and the output end of the telescopic member 32 is connected to the sliding seat 1. The sliding seat 1 is installed 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 implemented by a hydraulic telescopic member 32 or an electric telescopic rod, and the specific implementation form is not limited.

[0038] The moving assembly 3 may also use a bidirectional screw rod to achieve the position movement of the two sliding seats 1, and is not limited to the above-mentioned form of using the telescopic member 32.

[0039] See also Figure 2 In one embodiment, a plurality of triangular convex strips 331 are installed on the track 33 , which is slidably connected to the sliding seat 1 through the triangular convex strips 331 , and chip collecting grooves 332 are provided on both sides of the triangular convex strips 331 .

[0040] In this embodiment, a triangular ridge 331 is provided on the track 33, so that the sliding position of the sliding seat 1 can be moved by the triangular ridge 331. At the same time, the triangular structure of the triangular ridge 331 can guide the debris generated during the laser cutting process into the chip collecting groove 332, thereby preventing the debris from covering the triangular ridge 331 and affecting the movement of the sliding seat 1.

[0041] See also Fig.10 In one embodiment, the output end of the driving 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 mounted on the ring shaft 7, and the winding shaft 24 is connected to the main rope 25. The transmission assembly 8 is used to drive the first built-in tube 11, the second built-in tube 13 and the winding shaft 24 to rotate synchronously when the driving member 23 rotates forward, and drive the first built-in tube 11, the second built-in tube 13 and the winding shaft 24 to rotate relative to each other when the driving member 23 rotates reversely.

[0042] In this embodiment, when cutting, the positions of the two side sliding seats 1 are adjusted by moving the assembly 3, so that the hardware is placed between the two side sliding seats 1, and one end of the hardware is put on the outer side of the rotating rod 15 from one end of the first inner tube 11. Figure 8As can be seen from the figure, it is sleeved on the outside of the first built-in tube 11 from right to left. During the sleeve connection process, the rotating rod 15 can be 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 has been completely fixed. The hardware is locked at this time by the obliquely arranged rotating rod 15. During the sleeve connection process, the hardware can only move from right to left, but 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 built-in tube 13 actively sleeves the hardware until the other end of the hardware is in close contact with the baffle 9. At this time, the clamping of the hardware is completed. The present invention is adapted to flat tubes and other long strip structures of any irregular shape by arranging the rotating rods 15 on both sides of the first built-in tube 11 and the second built-in tube 13. As long as there is a symmetrical structure, Yes, due to the existence of the symmetrical structure, the inner wall of the hardware can be clamped by the rotating rod 15. After the clamping is completed, the position of the laser cutting head 4 is adjusted by starting the position adjustment component 5, so as to complete the cutting of the pattern shape on the surface of the hardware. In addition, when the driving member 23 rotates forward, the first built-in tube 11, the second built-in tube 13 and the winding shaft 24 are driven to rotate synchronously through the transmission component 8, so that the hardware can be cut. When the cutting is completed, the sliding seats 1 on both sides are first moved away by the moving component 3, and then the driving member 23 is started, so that the driving member 23 is reversed and the transmission component 8 drives the first built-in tube 11, the second built-in tube 13 and the winding shaft 24 to rotate relative to each other, that is, the winding shaft 24 rotates, while the first built-in tube 11 and the second built-in tube 13 remain stationary, and the main rope 25 can be wound. After winding, the rotating rod 15 cancels the tightness on the inner wall of the hardware. At this time, the cut hardware can be taken out.

[0043] See also Figure 7 , Fig.11 In one embodiment, a sleeve 12 is installed at one end of the first built-in tube 11 close to the second built-in tube 13, and a moving rod 14 is installed at one end of the second built-in tube 13 close to 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, when cutting, the positions of the two side sliding seats 1 are adjusted by moving the assembly 3, so that the hardware is placed between the two side sliding seats 1, and one end of the hardware is put on the outer side of the rotating rod 15 from one end of the first inner tube 11. Figure 8As can be seen in the figure, it is sleeved from right to left on the outside of the first built-in tube 11. During the sleeve connection process, the rotating rod 15 can be 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 has been completely fixed. Through the obliquely arranged rotating rod 15, the hardware is locked at this time. During the sleeve connection process, the hardware can only move from right to left, but not 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. The second built-in tube 13 actively sleeves the hardware. During the sleeve process, the moving rod 14 is inserted into the moving groove 121, so that the first built-in tube 11 and the second built-in tube 13 form a whole, until the other end of the hardware is close to the baffle 9. At this time, the clamping of the hardware is completed. The moving rod 14 and the sleeve 12 can keep the first built-in tube 11 and the second built-in tube 13 stable when rotating. At the same time, after the hardware is cut off, the hardware can be evenly locked to avoid the middle position being vacant, which causes the hardware to fall off after cutting off. Secondly, after the hardware is cut off, The lower incision is made. When leaving the incision, the sliding seats 1 on both sides are driven to move closer by the moving assembly 3, so that the cut hardware can be reassembled, thereby improving the overall stability of the hardware. In the present invention, by setting the rotating rod 15 on both sides of the first built-in tube 11 and the second built-in 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 inner wall of the hardware can be clamped by the rotating rod 15 through the existence of the symmetrical structure. After the clamping is completed, the position of the laser cutting head 4 is adjusted by starting the position adjustment assembly 5. The hardware can be cut by the driving member 23. In the present invention, even if the cutting process is performed, the hardware divided into two parts is still locked on the first inner tube 11 and the second inner tube 13, so that the next cutting process can be continued. When the cutting is completed, the sliding seats 1 on both sides are first moved away by the moving component 3, and then the main rope 25 is wound. After the winding, the rotating rod 15 cancels the tightness against the inner wall of the hardware. At this time, the cut hardware can be taken out.

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 located in the same plane, the movable plate 83 is located at the right-angled side of the trapezoidal groove 92. At this time, when the ring shaft 7 rotates, the baffle plate 9 can be driven 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 annular groove 91. At this time, when the ring shaft 7 rotates, the baffle plate 9 remains stationary and can drive the winding shaft 24 to rotate. The main rope 25 can be wound through relative rotation, so that the rotating rods 15 on both sides are close 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.

[0047] The transmission assembly 8 can also be realized by a telescopic rod, which is extended into the trapezoidal groove 92 to realize synchronous rotation, and relative rotation can be realized when the telescopic rod is retracted.

[0056] Working process of the present invention: When cutting, firstly, the positions of the two side sliding seats 1 are adjusted by moving the assembly 3, so that the hardware is placed between the two side sliding seats 1, and one end of the hardware is put on the outer side of the rotating rod 15 from one end of the first inner tube 11, and then the hardware is cut. Figure 8As can be seen from the figure, it is sleeved on the outside of the first built-in tube 11 from right to left. During the sleeve connection process, the rotating rod 15 can be 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 has been completely fixed. The hardware is locked at this time by the obliquely arranged rotating rod 15. During the sleeve connection process, the hardware can only move from right to left, but 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 assembly 3, so that the second built-in tube 13 actively sleeves the hardware until the other end of the hardware is tightly attached to the baffle 9. During the sleeve connection process, the moving rod 14 will be inserted into the moving groove 121, so that the first built-in tube 11 and the second built-in tube 13 form a whole, until the other end of the hardware is tightly attached to the baffle 9. At this time, the clamping of the hardware is completed, and the moving rod 14 and the sleeve are provided. 12 can remain stable when the first built-in tube 11 and the second built-in tube 13 rotate. After clamping is completed, the position of the laser cutting head 4 is adjusted by starting the position adjustment component 5, so as to complete the cutting of the pattern shape on the surface of the hardware. In addition, when the movable plate 83 and the fixed plate 81 are located in 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 baffle 9 can be driven to rotate by 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, 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 annular groove 91. At this time, when the ring shaft 7 rotates, the baffle 9 remains stationary and can drive the winding shaft 24 to rotate.
