Description

Technical Field

[0001] This utility model belongs to the field of cutting machines, specifically relating to a high-speed, high-precision cutting machine. Background Technology

[0002] With the rapid development of modern processing industry, the processing technology of sheet metal parts has become increasingly mature. Currently, most sheet metal parts are cut using CNC laser cutting. In order to further reduce damage and improve efficiency, non-contact cutting technology has developed rapidly. It uses a high-energy-density laser beam to melt or vaporize materials to achieve non-contact cutting, which is suitable for material processing scenarios that are sensitive to damage, have high dimensional accuracy requirements, or have complex shapes.

[0003] Currently, precision cutting machines rely on guide components to achieve multi-axis displacement control of the laser cutting head during operation. They complete the precise cutting of metal parts through the coordinated movement of longitudinal and transverse directions. However, a large amount of metal processing dust generated during the cutting process will fall and deposit on the surface of the guide components. Long-term accumulation can easily cause blockage of the guide gap or movement stagnation, significantly affecting the dynamic stability of the guide system. Meanwhile, the existing structure uses a single transmission screw as the core for guidance and drive. During operation, it will generate significant resistance due to continuous friction, which not only exacerbates the wear of the screw itself, but also reduces the smoothness of the laser cutting head's movement, ultimately reducing the cutting positioning accuracy and overall processing quality. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed, high-precision cutting machine.

[0005] A high-speed, high-precision cutting machine includes a processing chamber, a control module, and a filter plate. The control module is located on the outside of the processing chamber. A sliding door is connected to a track on one side of the processing chamber, and a hopper trolley is connected through one side of the processing chamber. A dust extraction hole is located on the back of the processing chamber. A processing mechanism is located inside the processing chamber. According to the cutting requirements, the processing mechanism adjusts the position of a right-angle cylinder and a side positioning plate longitudinally and laterally, thereby vertically raising and lowering the laser cutting head via the right-angle cylinder to cut the surface of the workpiece. A clamping mechanism is located directly below the workpiece. During workpiece processing, the clamping mechanism adjusts the distance between two symmetrically arranged clamping arms according to the size of the workpiece. Simultaneously, it releases the clamped workpiece after processing to complete material unloading. A shielding mechanism is located at the bottom of the processing mechanism. During the operation of the processing mechanism, the shielding mechanism shields the surface of the processing mechanism to prevent cutting dust from falling onto the surface of the guide assembly. A workpiece storage cabinet is located inside the processing chamber. A filter screen is installed inside the processing chamber, and the filter screen is parallel to the dust suction holes.

[0006] Preferably, the processing mechanism includes a linear motor magnetic levitation module, a cable chain, a right-angle cylinder, a side positioning plate, a vertical guide frame, and a cylinder support. The linear motor magnetic levitation module is disposed inside the processing chamber. A cable chain is disposed on one side of the linear motor magnetic levitation module, and the linear motor magnetic levitation module is connected to one side of the cable chain. A cylinder support is disposed on the other side of the cable chain. The linear motor magnetic levitation module is connected to the bottom end of the cylinder support through a magnetic levitation module mover. A right-angle cylinder is connected to the outside of the cylinder support. The output end of the right-angle cylinder is connected to the side positioning plate. The vertical guide frame is connected to the outside of the side positioning plate through a guide rod.

[0007] Preferably, the linear motor magnetic levitation module is connected to the outside of the right-angle cylinder via a cylinder bracket set at the top, and the right-angle cylinder is connected to the outside of the side positioning plate via a vertical guide frame connected to the outside.

[0008] Preferably, the linear motor magnetic levitation module and the control module are electrically connected, and the control module includes an LCD display, a control button switch box, a keyboard and mouse box, and a three-color warning light.

[0009] Preferably, the clamping mechanism includes a clamping arm, an electric cylinder, a side rubber pad, a slot strip, a slider, a serrated rack, and a linear guide rail. The clamping arm is symmetrically arranged inside the machining chamber, and a side rubber pad is connected to one side of the clamping arm. The electric cylinder is located on one side of the linear guide rail, and a slider is connected to the output end of the linear guide rail. The slot strip is symmetrically installed on the table of the machining chamber, and the slot strip is connected to both ends of the serrated rack through slots that are equally spaced on the outer side. The slider is symmetrically arranged at the bottom end of the clamping arm.

[0010] Preferably, the processing chamber is connected to both ends of the saw blade by symmetrically arranged slot strips, and a rectangular opening structure is provided between the two sets of slot strips. The rectangular opening structure is parallel to the unloading hopper.

[0011] Preferably, the electric cylinder is connected to the bottom end of the clamping arm via a slider connected to the output end, and the clamping arm and the side rubber pads of the "L"-shaped structure are symmetrically distributed on the other two sides of the rectangular open structure.

[0012] Preferably, the shielding mechanism includes a C-shaped frame, flexible fabric, a second linear guide rail, an energized excitation coil, a steel rail, and a side support base. The C-shaped frame is evenly spaced above the steel rail, and the steel rail is fitted against the internal tabletop of the processing chamber. The second linear guide rail is provided on both sides of the steel rail, and an energized excitation coil is provided directly above the steel rail. The energized excitation coil is installed at the bottom of the side support base, and a linear motor magnetic levitation module is connected to the top of the side support base. The flexible fabric is sewn between the two sets of C-shaped frames.

[0013] Preferably, the flexible fabric is connected to the second linear guide rail via C-shaped frames on both sides. The C-shaped frames and the flexible fabric are distributed at equal intervals on both sides of the second linear guide rail, and two sets of the C-shaped frames are connected to the side support seats.

[0014] The advantages of this utility model are: 1. This utility model uses a clamping mechanism to form a horizontal clamping and vertical pressing dual positioning by symmetrically setting L-shaped side rubber pads and the side positioning plate of the processing mechanism. The side rubber pads elastically deform to fit the side of the workpiece, providing uniform clamping force. The side positioning plate descends along the vertical guide frame to the top surface of the workpiece, achieving precise vertical positioning. After the two work together, the overall positioning accuracy of the workpiece is improved. At the same time, the slots of the serrated strip and the slot strip engage, and the bottom end of the bottom workpiece fits with the top end of the serrated strip, which plays a role in preventing loosening and slipping. The serrated strip is used to divide the workpiece of the same size into middle parts and then clamp it through the clamping mechanism.

[0015] 2. The motor magnetic levitation module achieves frictionless lateral displacement through a rigid connection between the magnetic levitation mover and the cylinder bracket, solving the problem of accuracy attenuation caused by friction in traditional lead screws. The right-angle cylinder and the vertical guide frame are rigidly connected to the cylinder bracket through bolts. The modular design allows for the individual replacement of damaged parts without disassembling the entire mechanism. The machining mechanism is driven by a linear motor magnetic levitation module, which achieves longitudinal or lateral displacement through the non-contact action between the magnetic levitation mover and the stator.

[0016] 3. The C-shaped frame and flexible fabric are evenly distributed on both sides of the linear guide rail, and some of the C-shaped frames are directly connected to the side support seats to ensure that the flexible fabric is subjected to uniform force, avoid local wrinkles or loosening, and improve the flatness and sealing of the shield. After the excitation coil is energized, it generates electromagnetic force with the rail or C-shaped frame to achieve precise positioning and stable clamping of the C-shaped frame, ensuring the accuracy of the shield position. At the same time, the flexible fabric adapts to the processing chamber space to form a closed or semi-closed shield, isolating splashes and dust during the processing. Attached Figure Description

[0020] like Figures 1 to 8 As shown, a high-speed, high-precision cutting machine includes a processing chamber 1, a control module 2, and a filter plate 10. The control module 2 is located on the outside of the processing chamber 1. A sliding door 3 is connected to a track on one side of the processing chamber 1.

The processing mechanism 6 adjusts the position of the right-angle cylinder 63 and the side positioning plate 64 longitudinally and laterally according to the cutting requirements. The right-angle cylinder 63 then vertically raises and lowers the laser cutting head to cut the surface of the workpiece. A clamping mechanism 7 is provided directly below the mechanism 6. During workpiece processing, the clamping mechanism 7 adjusts the distance between two symmetrically arranged clamping arms 71 according to the size of the workpiece. At the same time, it releases the clamped workpiece after processing to complete material unloading. A shielding mechanism 8 is provided at the bottom of the processing mechanism 6.

A workpiece storage cabinet 9 is provided inside the processing chamber 1. A filter screen 10 is provided inside the processing chamber 1. The filter screen 10 is parallel to the dust suction hole 5.

[0021] The processing mechanism 6 includes a linear motor magnetic levitation module 61, a cable chain 62, a right-angle cylinder 63, a side positioning plate 64, a vertical guide frame 65, and a cylinder bracket 66. The linear motor magnetic levitation module 61 is disposed inside the processing chamber 1. A cable chain 62 is disposed on one side of the linear motor magnetic levitation module 61, and the linear motor magnetic levitation module 61 is connected to one side of the cable chain 62. A cylinder bracket 66 is disposed on the other side of the cable chain 62. The linear motor magnetic levitation module 61 is connected to the bottom end of the cylinder bracket 66 through a magnetic levitation module mover. The cylinder bracket 66 is externally... A right-angle cylinder 63 is connected to the side, and the output end of the right-angle cylinder 63 is connected to a side positioning plate 64. The vertical guide frame 65 is connected to the outside of the side positioning plate 64 through a guide rod.

The control module 2 includes an LCD display, a control button switch box, a keyboard and mouse box, and a three-color warning light.

[0022] The clamping mechanism 7 includes a clamping arm 71, an electric cylinder 72, a side rubber pad 73, a slot strip 74, a slider 75, a serrated bar 76, and a linear guide rail 77. The clamping arm 71 is symmetrically arranged inside the machining chamber 1, and a side rubber pad 73 is connected to one side of the clamping arm 71. The electric cylinder 72 is located on one side of the linear guide rail 77, and a slider 75 is connected to the output end of the linear guide rail 77. The slot strip 74 is symmetrically installed on the table surface of the machining chamber 1, and the slot strip 74 is secured by slots that are equally spaced on its outer side. The slots connect both ends of the saw blade 76, and the sliders 75 are symmetrically arranged at the bottom of the clamping arm 71; the processing chamber 1 is connected to both ends of the saw blade 76 by symmetrically arranged slot strips 74, and a rectangular opening structure is provided between the two sets of slot strips 74, which is parallel to the unloading hopper 4; the electric cylinder 72 is connected to the bottom of the clamping arm 71 by the slider 75 connected to the output end, and the clamping arm 71 and the side rubber pads 73 of the "L"-shaped structure are symmetrically distributed on the other two sides of the rectangular opening structure; Simultaneously, the electric cylinder 72 drives the slider 75 to move the clamping arm 71 along the linear guide rail 77. The distance between the two sets of clamping arms 71 is adjusted according to the workpiece width. The target position is locked by the slot strip 74 and the serrated strip 76. The workpiece is placed by the feeding device in the rectangular opening area between the slot strip 74. The clamping arm 71 clamps the workpiece under the drive of the electric cylinder 72. The side rubber pad 73 fits against the side of the workpiece to provide stable clamping force. After the cutting is completed, the right-angle cylinder 63 retracts and the side positioning plate 64 rises to avoid the workpiece. The electric cylinder 72 drives the slider 75 in the opposite direction, and the clamping arm 71 releases the workpiece. The workpiece is received by the unloading hopper 4 parallel to the rectangular opening and is automatically transported out of the processing chamber 1.

[0023] The shielding mechanism 8 includes a C-shaped frame 81, flexible fabric 82, linear guide rails 83, energized excitation coils 84, steel rails 85, and side support seats 86. The C-shaped frames 81 are evenly spaced above the steel rails 85, which are fitted against the internal tabletop of the processing chamber 1. Linear guide rails 83 are arranged on both sides of the steel rails 85, and energized excitation coils 84 are arranged directly above the steel rails 85. The energized excitation coils 84 are installed at the bottom of the side support seats 86, and a linear motor magnetic levitation module 61 is connected to the top of the side support seats 86. The flexible fabric 82 is sewn between the two sets of C-shaped frames 81. The flexible fabric 82 is connected to the linear guide rails 83 through the C-shaped frames 81 arranged on both sides. The C-shaped frames 81 and the flexible fabric 82 are evenly distributed on both sides of the linear guide rails 83, and the two sets of C-shaped frames 81 are connected to the side support seats 86.

[0024] The flexible fabric 82 is sewn between the two sets of C-shaped frames 81 to form a retractable curtain-like shielding structure. When the side support seat 86 moves along the linear guide rail 83 under the drive of the linear motor magnetic levitation module 61, it will pull the C-shaped frame 81 connected to it, thereby stretching the flexible fabric 82. When the side support seat 86 moves along the magnetic levitation module, it will simultaneously pull the C-shaped frame 81 fixed to it. The flexible fabric 82 between the two sets of C-shaped frames 81 is stretched and unfolded with the frame displacement to form a continuous covering layer, accurately shielding the exposed areas of the linear guide rail 83 and the steel rail 85 below.

[0025] When this utility model is in operation, the linear motor magnetic levitation module 61 is first fixed on the central axis inside the processing chamber 1, serving as the bearing foundation of the processing mechanism 6. The linear motor magnetic levitation module 61 achieves lateral frictionless displacement through the rigid connection between the magnetic levitation mover and the cylinder bracket 66. The magnetic levitation stator is embedded in the frame of the linear motor magnetic levitation module 61, and the mover is rigidly connected to the bottom end of the cylinder bracket 66 through bolts, ensuring that the mover moves synchronously to drive the cylinder bracket 66 and the upper actuator. The operator can connect the dust suction hole 5 to the input end of the vacuum cleaner. When the workpiece is being cut, the vacuum cleaner sucks in the air and the cutting dust, while using the filter screen 10 to filter large particulate impurities in the air to prevent large particulate debris from damaging the vacuum cleaner. The side support seat 86 is driven by the linear motor magnetic levitation module 61, which drives the C-shaped frame 81 connected to it to move along the linear guide rail 83. Since the flexible fabric 82 is sewn between the two sets of C-shaped frames 81, when the side support seat 86 moves, it will pull the flexible fabric 82, causing it to unfold or retract, covering or leaving the processing area. After the energized excitation coil 84 is energized, it may generate an electromagnetic attraction with the steel rail 85, generating an electromagnetic force to achieve the positioning of the C-shaped frame 81. A right-angle cylinder 63 is installed on one side of the top surface of the cylinder bracket 66, with the cylinder axis parallel to the width direction of the processing chamber 1. The side positioning plate 64 is driven to move along the vertical guide frame 65 by the extension and retraction of the piston rod, thereby realizing the lifting structure treatment of the laser cutting head. It is connected to the end of the piston rod of the right-angle cylinder 63 through a joint bearing, and the back is rigidly connected to the guide rod of the vertical guide frame 65. The vertical guide frame 65 is fixed to the other side of the top surface of the cylinder bracket 66 and is arranged parallel to the right-angle cylinder 63. The control module 2 sends a command, and the linear motor magnetic levitation module 61 drives the actuator, along with the cylinder bracket 66, the right-angle cylinder 63 and the side positioning plate 64, to move longitudinally or laterally to the processing start position. The right-angle cylinder 63 is activated, pushing the side positioning plate 64 down along the vertical guide frame 65 to clamp the workpiece in cooperation with the clamping mechanism 7. After positioning is completed, the cylinder retracts and the side positioning plate 64 rises to avoid the cutting path.

[0026] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
