Description

Technical Field

[0001] This invention relates to the field of cutting machines, and in particular to a laser cutting machine specifically for air guide rings. Background Technology

[0002] Currently, the forming and processing of air guide rings mostly adopts the die stamping method. However, different specifications of air guide rings require different dies, resulting in cumbersome processes, high die costs, and time-consuming replacements. In addition, the edges of the holes produced by stamping have burrs, which require secondary grinding, increasing processing costs and lengthening the production cycle.

[0003] Although laser cutting technology has advantages such as no need for molds, direct modification of processing trajectory, and smooth, burr-free cut edges, existing planar laser cutting machines cannot process workpieces like air guide rings with a particularly large height difference between the upper and lower processing surfaces (≥150mm), for the following reasons: 1. When machining the lower surface of the air guide ring, the movement trajectory of the flat cutting head will interfere with the slope of the air guide ring. Although using a robotic arm or a 3D five-axis laser cutting machine can allow the cutting head to swing at a certain angle to avoid the slope, this will cause the cut edge to become a bevel rather than the required vertical surface, which cannot meet the machining accuracy requirements.

[0004] 2. Because the upper surface of the air guide ring has a large circular hole and the drop surface is curved, the center of the workpiece cannot be determined by the traditional capacitor edge-tracking method, which increases the complexity and difficulty of the processing. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a laser cutting machine specifically for air guide rings. The processing trajectory of the laser cutting head can avoid the high drop slope of the air guide ring, and the centering and positioning plate can be used to assist in capacitive edge finding to determine the processing center point.

[0006] The technical solution of the present invention is a laser cutting machine for a guide ring, comprising a machine body, a laser cutting head, a support component, and a positioning component; the machine body is provided with a three-dimensional moving module for adjusting the three-dimensional spatial position of the laser cutting head; the support component includes a base disposed on the machine body and a plurality of support platforms disposed on the base; the positioning component includes a bracket mounted on the base, a plurality of positioning pins disposed on the bracket, and a centering positioning plate having a plurality of insertion holes and being detachably inserted into the positioning pins through the insertion holes, the centering positioning plate being a rectangular plate.

[0007] Preferably, the support platform has a threaded hole.

[0008] Preferably, a crossbeam grating is provided at both ends of the three-dimensional moving module.

[0009] Preferably, the base has a connection hole and a lifting ring is provided on the base.

[0010] Preferably, a cylinder is horizontally mounted on the body and located on the side of the positioning component.

[0011] Preferably, the machine body is equipped with an operating table, which is connected to the three-dimensional moving module, the laser cutting head, and the cylinder control.

[0012] Preferably, a feed roller located below the support assembly is provided along the inclined direction on the machine body.

[0013] Preferably, a waste trolley is provided on one side of the bottom end of the feeding roller.

[0014] Preferably, the insertion holes on the centering plate are arranged in multiple rings from the center outwards.

[0015] Preferably, the method of using the above-mentioned laser cutting machine includes the following steps: S1. Insert the centering plate into the corresponding positioning pin through the socket to assist in capacitor edge finding, determine the processing center point and save the coordinates. S2. After the laser cutting head completes the positioning of the processing center point, the centering and positioning plate is removed, and the air guide ring to be processed is placed on it. The upper inner side of the air guide ring is supported and positioned by the positioning pin, and the bottom outer periphery of the air guide ring is supported by multiple support platforms. The air guide ring is placed in the center. S3: The three-dimensional moving module adjusts the three-dimensional spatial position of the laser cutting head and uses the laser cutting head to perform laser cutting processing on the air guide ring.

[0016] Compared with existing technologies, the present invention has the following beneficial technical effects: the laser cutting head is more slender than ordinary planar cutting heads, and its movement trajectory can avoid the slope of the air guide ring when processing the lower processing surface, maintaining a safe distance from the slope, thereby achieving interference-free cutting of workpieces with high drops, and keeping the cut edge perpendicular to the plane. In addition, the cutting machine can also use a detachable centering positioning plate to perform auxiliary capacitor edge finding to determine the processing center point, ensuring the accuracy and quality of laser cutting.

Detailed Implementation

[0019] like Figures 1-5 As shown in the figure, the laser cutting machine for air guide rings proposed in this embodiment includes a machine body 1, a laser cutting head 3, a support component and a positioning component, which can perform laser cutting processing on air guide rings 100. The upper part of the air guide ring 100 is a ring structure, the lower outer edge is a chamfered square, and the four corners of the lower outer perimeter have through holes.

[0020] like Figure 1 and Figure 4 As shown, a three-dimensional moving module 2 for adjusting the three-dimensional spatial position of the laser cutting head 3 is provided on the machine body 1. The three-dimensional moving module 2 includes a transverse frame 21, a slider one, a slide rail one 24 horizontally set on the machine body 1 for sliding the slider one, a motor one 22 set on the transverse frame 21, a gear one set on the output end of the motor one 22, a rack one 23 horizontally set on the machine body 1 and meshing with the gear one, a slide rail two 28 set on the transverse frame 21, a translation frame 25 slidably set on the slide rail two 28 via the slider two, a motor two 26 set on the translation frame 25, a gear two set on the output end of the motor two 26, a rack two 27 horizontally set on the transverse frame 21 and meshing with the gear two, a motor three 29 set on the translation frame 25, and a lead screw module 291 driven by the motor three 29. The laser cutting head 3 is installed at the moving end of the lead screw module 291. Motor 22 drives gear 1 to rotate, causing gear 1 to roll on rack 23, thus adjusting the position of the laser cutting head 3 in the Y-axis direction. Similarly, motor 26 drives gear 2 to rotate, causing gear 2 to roll on rack 27, thus adjusting the position of the laser cutting head 3 in the X-axis direction. Motor 3 29 adjusts the height of the laser cutting head 3 via the existing lead screw module 291. The laser cutting head 3 has a three-dimensional, pointed, slender structure to avoid the slope of the air guide ring 100 during processing. The laser cutting head 3 maintains a safe distance of approximately 5mm from the slope of the air guide ring 100. The laser cutting head 3 is fastened to the lead screw module 291 with bolts.

[0021] Both ends of the three-dimensional moving module 2 are equipped with crossbeam gratings 4. The height of the light curtain of the crossbeam gratings 4 is higher than the highest point of the air guide ring 100 to prevent the air guide ring 100 from blocking the machine and causing it to stop. It also stops the machine immediately if the operator touches it, ensuring safety. A feeding roller 11 is provided on the machine body 1 along the inclined direction and located below the support component. The waste material cut off by the laser cutting head 3 from the air guide ring 100 falls to the feeding roller 11 and slides down along the feeding roller 11. A waste trolley 12 is provided on one side of the bottom of the feeding roller 11 to receive the sliding waste material.

[0022] like Figure 1 and Figure 2 As shown, the support assembly includes a base 5 mounted on the machine body 1 and several support platforms 6 mounted on the base 5. Each support platform 6 has a threaded hole 601. For the guide ring 100 to be cut, since laser cutting requires the guide ring 100 to be suspended, the support platform 6 supports the guide ring 100 and avoids the processing trajectory. The guide ring 100 is placed on the support platform 6 for support, and the threaded hole 601 is aligned with the through hole on the guide ring 100. Bolts are then tightened to fix the guide ring 100, ensuring the quality of subsequent cutting by the laser cutting head 3.

[0023] The positioning assembly includes a bracket 7 mounted on a base 5, several positioning pins 8 mounted on the bracket 7, and a centering positioning plate 14 with several insertion holes that can be detachably inserted into the positioning pins 8. The bracket 7 has a ring structure, and multiple positioning pins 8 are installed in a ring on the bracket 7. The centering positioning plate 14 is a rectangular plate, preferably a square plate, with a side length of 1000mm and a thickness of 5mm. The insertion holes on the centering positioning plate 14 are arranged in multiple rings from the center outwards, which can be used for centering positioning of different specifications of support components and positioning components. Simply insert the centering positioning plate 14 into the positioning pins 8 that are distributed in different positions in different specifications of positioning components through the corresponding insertion holes. During positioning, the centering positioning plate 14 is installed in advance, the auxiliary capacitor edge finding is used to determine the processing center point and save the coordinates. After the laser cutting head 3 completes the positioning of the processing center point, the centering positioning plate 14 is removed and the air guide ring 100 to be processed is placed on it. The upper inner side of the air guide ring 100 is supported and positioned by the positioning pin 8, while the bottom periphery of the air guide ring 100 is supported by multiple support platforms 6. After the air guide ring 100 is placed in the center, bolts are screwed onto the support platforms 6 to tighten the air guide ring 100, ready for laser cutting. After the initial centering, as long as the support and positioning components are not replaced, subsequent processing does not require re-centering.

[0024] like Figure 2As shown, the base 5 has connecting holes, and the base 5 can be installed onto the body 1 by bolts, which facilitates disassembly and assembly on the body 1. The base 5 is provided with lifting rings 9, which are used to lift and lower the base 5 after disassembly, making it easy to replace the support components and positioning components of different specifications to adapt to the support and positioning of the air guide rings 100 of different specifications.

[0025] like Figure 1 As shown, a cylinder 10 is horizontally mounted on the side of the positioning component on the machine body 1. At least two cylinders 10 are arranged side by side. After the air guide ring 100 is placed on the support platform 6 and the positioning pin 8, the cylinder 10 extends and pushes the lower edge of the air guide ring 100, so that the air guide ring 100 can better fit the curved part of the top of the positioning pin 8, and align the air guide ring 100 in the X and Y directions. After the cutting machine imports the corresponding processing drawing, laser cutting begins. An operating table 13 is provided on the machine body 1. The operating table 13 is connected to the three-dimensional moving module 2, the laser cutting head 3 and the cylinders 10 for control, and can perform corresponding control operations.

[0026] The above-mentioned laser cutting machine is used in the following steps: S1. Insert the centering plate 14 into the corresponding positioning pin 8 through the insertion hole to assist in capacitor edge finding, determine the processing center point and save the coordinates. S2. After the laser cutting head 3 completes the positioning of the processing center point, the centering and positioning plate 14 is removed and the air guide ring 100 to be processed is placed on it. The upper inner side of the air guide ring 100 is supported and positioned by the positioning pin 8, and the bottom periphery of the air guide ring 100 is supported by multiple support platforms 6. The air guide ring 100 is placed in the center to ensure the accuracy of subsequent laser cutting. S3. The three-dimensional moving module 2 adjusts the three-dimensional spatial position of the laser cutting head 3 and uses the laser cutting head 3 to perform laser cutting processing on the air guide ring 100.

[0027] In this embodiment, the laser cutting head 3 is more slender than a conventional planar cutting head. Its movement trajectory avoids the slope of the air guide ring 100 when processing the lower surface, maintaining a safe distance of approximately 5mm from the slope. This achieves interference-free cutting of workpieces with significant height differences, while ensuring the cut edge remains perpendicular. Furthermore, this cutting machine can utilize a detachable centering and positioning plate 14 for auxiliary capacitive edge finding to determine the processing center point, facilitating centering and positioning and ensuring laser cutting accuracy and quality.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
