Description

Technical Field

[0001] This invention belongs to the field of laser cutting machine technology, specifically relating to a laser cutting machine for sheet metal used in the production of power equipment. Background Technology

[0002] A laser cutting machine is a device that uses a high-power laser beam to cut materials, typically used for processing metals, plastics, wood, and other materials. The laser cutting machine heats the material to the point of melting or evaporation through the high temperature of the laser beam, creating a cut. Its main advantages include high cutting precision, smooth cutting edges, high automation, and the ability to handle complex shapes. Its working principle is roughly as follows: A laser source generates a laser beam, which is focused onto the surface of the material to be cut using a reflector and a focusing lens. The high-temperature laser irradiates the material, causing it to melt or evaporate rapidly. A gas (such as oxygen, nitrogen, or air) is used to blow away the molten material, completing the cutting process.

[0003] Laser cutting machines used in power equipment manufacturing are typically used for the precise cutting of various metal plates, especially steel, aluminum, and copper plates. These materials are common basic materials in power equipment manufacturing. Using laser cutting machines can improve production efficiency, ensure high-precision cutting quality, and reduce material waste. Currently, there are many different types of laser cutting machines on the market, but most sheet metal laser cutting machines have relatively simple structural designs and rely on manual loading, which is not only time-consuming and labor-intensive but also cannot guarantee that the sheet metal can be placed quickly and accurately, requiring repeated adjustments. Alternatively, the laser cutting machine can first scan and position the sheet metal using a laser positioner and then automatically adjust the laser cutting path. Although this method can also complete laser cutting, it is also very time-consuming, which will affect processing efficiency and progress to some extent. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a laser cutting machine for sheet metal production of power equipment.

[0005] The technical solution adopted to solve the above technical problems is: a plate laser cutting machine for power equipment production, including a cutting platform, a plate support mechanism for supporting metal plates is fixedly connected to the top center of the cutting platform, and symmetrically arranged longitudinal moving mechanisms are fixedly connected to both sides of the top of the cutting platform. A transverse moving mechanism is fixedly connected between the two sets of longitudinal moving mechanisms, and a lifting and cutting mechanism for cutting metal sheets is installed on the transverse moving mechanism. The cutting platform is equipped with an automatic feeding mechanism at its rear end. A plate positioning mechanism for pre-positioning metal plates is slidably installed on one side of the top of the automatic feeding mechanism. The automatic feeding mechanism can automatically feed the metal plates to the designated processing position on the top of the plate support mechanism by flipping. Waste collection troughs for collecting cutting waste are placed on both sides of the bottom of the cutting platform.

[0006] Furthermore, the cutting platform includes a cutting frame, a support frame is fixedly connected to the middle of the cutting frame, and multiple material collection hoppers are installed on the support frame.

[0007] Through the above technical solution, the cutting platform, as the main support structure, can provide stable support for the various mechanisms at the top. At the same time, the multiple hoppers installed on the support frame can collect the waste generated during the cutting process, so that the waste can be collected in the waste collection trough.

[0008] Furthermore, the plate support mechanism includes two side supports fixed to the top of the cutting platform on both sides, and a central support fixedly connected to the top center of the cutting platform. The top of the central support and the top of the two side supports are provided with multiple evenly distributed positioning slots, and a support strip is installed in each set of positioning slots.

[0009] Through the above technical solution, the sheet metal support mechanism is mainly used for supporting and placing the metal sheet to be processed. Multiple support bars with serrated tops can form multi-point support for the metal sheet, which can not only form a stable support structure, but also prevent a large amount of metal jet generated during the cutting process from adhering to the top of the support bars. At the same time, the support bars are installed by plugging, so they can be quickly disassembled and replaced.

[0010] Furthermore, the longitudinal moving mechanism includes a longitudinal support guide rail fixed to one side of the top of the cutting platform. The top and outer sides of the longitudinal support guide rail are both fixedly connected to longitudinal limiting slide rails. A first fixed rack is also fixedly connected to the outer side of the longitudinal support guide rail. A longitudinal moving slide is slidably mounted on the longitudinal support guide rail. A first servo motor is mounted on the top of the longitudinal moving slide. A first drive gear that meshes with the first fixed rack is fixedly mounted on the output end of the first servo motor.

[0011] Through the above technical solution, the longitudinal moving mechanism can drive the transverse moving mechanism and the lifting cutting mechanism to move longitudinally and horizontally. During operation, the first servo motor can drive the first drive gear to rotate synchronously through its output shaft. Since the first drive gear meshes with the first fixed rack, it can drive the entire longitudinal moving slide to slide back and forth on the longitudinal support guide rail. This can cooperate with the transverse moving mechanism to drive the lifting cutting mechanism to freely slide and adjust its longitudinal and transverse positions, thereby completing the precise cutting of metal plates according to the programmed program.

[0012] Furthermore, the lateral movement mechanism includes a support beam fixed between two sets of longitudinal movement mechanisms. The top and rear ends of the support beam are fixedly connected to lateral limiting slide rails. The rear end of the support beam is also fixedly connected to a second fixed rack. A lateral movement slide is slidably mounted on the support beam. A second servo motor is fixedly mounted on the top and rear ends of the lateral movement slide. A second drive gear that meshes with the second fixed rack is fixedly mounted on the output end of the second servo motor.

[0013] Through the above technical solution, the lateral moving mechanism can drive the lifting and cutting mechanism to move laterally. During operation, the second servo motor can drive the second drive gear to rotate synchronously through its output shaft. Since the second drive gear meshes with the second fixed rack, it can drive the entire lateral moving slide to slide left and right on the support beam, thereby cooperating with the longitudinal moving mechanism to complete the precise cutting of the metal sheet.

[0014] Furthermore, the lifting and cutting mechanism includes a lifting transmission rack slidably mounted on the front end of the transverse moving slide, a first mounting base is fixedly connected to the top front end of the transverse moving slide, a third servo motor is mounted on the first mounting base, a third drive gear that meshes with the lifting transmission rack is fixedly mounted on the output end of the third servo motor, and a laser cutting component is fixedly mounted on the front end of the lifting transmission rack.

[0015] Through the above technical solution, the lifting and cutting mechanism, as the main cutting component, operates by having a third servo motor drive a third drive gear to rotate via its output shaft. This third drive gear then drives the lifting transmission rack and laser cutting component to move up and down. During the cutting process, the third servo motor moves the laser cutting component downwards, bringing its bottom end close to the metal sheet. During processing, the laser cutting component emits a high-temperature laser that irradiates the metal sheet, causing it to melt rapidly. Simultaneously, gas is ejected from its bottom nozzle, blowing away the molten material, thus completing the cutting process. With further driving of the longitudinal and transverse moving mechanisms, cuts of any shape can be made on the metal sheet.

[0016] Furthermore, the automatic feeding mechanism includes a support platform located at the rear end of the cutting platform. Two symmetrically arranged second mounting seats are fixedly connected to the top front end of the support platform. An L-shaped rotating arm is rotatably connected between the two second mounting seats. A fourth servo motor for driving the L-shaped rotating arm to rotate is installed on one of the second mounting seats. A negative pressure adsorption component is fixedly installed at the rear end of the L-shaped rotating arm. A cavity is provided in the middle of the negative pressure adsorption component. Multiple vacuum adsorption holes communicating with the cavity are opened on the top of the negative pressure adsorption component. A silicone pad is fixedly connected to the top of the negative pressure adsorption component. A vacuum pump communicating with the cavity is fixedly installed at the bottom of the negative pressure adsorption component.

[0017] Through the above technical solution, the automatic feeding mechanism is mainly used for automatic rotary feeding of metal sheets. During operation, the metal sheet can be placed horizontally on the top of the support platform and positioned directly above the negative pressure adsorption component. After the metal sheet is placed and positioned, the vacuum pump is started, which generates negative pressure suction in the cavity and multiple vacuum adsorption holes. The metal sheet will be tightly adsorbed and fixed on the silicone pad. At this time, the fourth servo motor is started, which drives the L-shaped rotating arm to rotate 180 degrees, so that the metal sheet on the top of the negative pressure adsorption component can be automatically placed at the designated position on the top of the sheet support mechanism, thereby completing the precise automatic feeding operation.

[0018] Furthermore, two limiting grooves are provided on one side of the top of the support platform.

[0019] Through the above technical solution, the two limiting grooves can guide and limit the sliding adjustment of the plate positioning mechanism.

[0020] Furthermore, the plate positioning mechanism includes a limiting angle steel that is slidably installed on one side of the top of the support platform. Two T-shaped limiting bolts pass through the limiting angle steel, and a fixing nut is threaded onto each of the two T-shaped limiting bolts. An auxiliary limiting component is also attached to the limiting angle steel, and a locking bolt is threaded onto the auxiliary limiting component.

[0021] Through the above technical solution, the plate positioning mechanism is mainly used for auxiliary positioning of metal plates. During processing, the positions of the limiting angle steel and auxiliary limiting components can be pre-adjusted according to the size of the metal plate. After the adjustment is completed, the fixing nuts and locking bolts are tightened respectively to fix their positions. Finally, the two adjacent sides of the metal plate to be processed are placed close to the limiting angle steel and auxiliary limiting components respectively to complete the precise pre-positioning of the metal plate.

[0022] Furthermore, the bottom ends of the two T-shaped limiting bolts slide within their respective limiting grooves.

[0023] The beneficial effects of the present invention are as follows: (1) By designing an automatic feeding mechanism and a plate positioning mechanism, the present invention can not only complete the precise pre-positioning of the metal plate, but also automatically feed the positioned metal plate to the designated cutting and processing position using a rotating arm, thereby saving a lot of manpower and material resources and ensuring the subsequent processing accuracy; (2) By designing a plate positioning mechanism, the present invention only needs to place the adjacent sides of the metal plate to be processed close to the limiting angle steel and the auxiliary limiting component respectively to complete the precise pre-positioning of the metal plate, thereby ensuring the subsequent feeding accuracy; (3) By designing a longitudinal moving mechanism, a transverse moving mechanism and a lifting cutting mechanism, the present invention can cut cuts of any shape on the metal plate as the longitudinal moving mechanism and the transverse moving mechanism are driven and adjusted.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] like Figures 1-16 As shown in the figure, a plate laser cutting machine for power equipment production in this embodiment includes a cutting platform 1. Both sides of the bottom of the cutting platform 1 are provided with waste collection troughs 8 for collecting cutting waste. The cutting platform 1 includes a cutting frame 101. A support frame 102 is fixedly connected to the middle of the cutting frame 101. Multiple collection hoppers 103 are installed on the support frame 102. The cutting platform 1 serves as the main support structure, which can provide stable support for the various mechanisms at the top. At the same time, the multiple collection hoppers 103 installed on the support frame 102 can collect the waste generated during the cutting process, so that the waste can be collected in the waste collection troughs 8.

[0028] Regarding plate support mechanism 2, please refer to... Figures 1-6The cutting platform 1 has a plate support mechanism 2 fixedly connected to the top center for supporting the metal plate 9. The plate support mechanism 2 includes two side supports 201 fixed to both sides of the top of the cutting platform 1, and a central support 202 fixedly connected to the top center of the cutting platform 1. The top of the central support 202 and the top of the two side supports 201 are provided with multiple evenly distributed positioning slots 203. Each set of positioning slots 203 is equipped with a support bar 204. The plate support mechanism 2 is mainly used for supporting and placing the metal plate 9 to be processed. The multiple support bars 204 with serrated tops can form multi-point support for the metal plate 9, which can not only form a stable support structure, but also prevent a large amount of metal jet generated during the cutting process from adhering to the top of the support bar 204. At the same time, the support bar 204 is installed by plugging, so it can be quickly disassembled and replaced.

[0029] Regarding longitudinal movement mechanism 3, refer to... Figures 1-8 The cutting platform 1 has symmetrically arranged longitudinal moving mechanisms 3 fixedly connected to both sides of its top. Each longitudinal moving mechanism 3 includes a longitudinal support guide rail 301 fixed to one side of the top of the cutting platform 1. Longitudinal limiting slide rails 302 are fixedly connected to the top and outer sides of the longitudinal support guide rail 301. A first fixed rack 303 is also fixedly connected to the outer side of the longitudinal support guide rail 301. A longitudinal moving slide block 304 is slidably mounted on the longitudinal support guide rail 301. A first servo motor 305 is mounted on the top of the longitudinal moving slide block 304. A first servo motor 305 is fixedly mounted at the output end of the first servo motor 305, which meshes with the first fixed rack 303. A drive gear 306 and a longitudinal moving mechanism 3 can drive a transverse moving mechanism 4 and a lifting and cutting mechanism 5 to move longitudinally and horizontally. During operation, a first servo motor 305 can drive the first drive gear 306 to rotate synchronously through its output shaft. Since the first drive gear 306 meshes with the first fixed rack 303, it can drive the entire longitudinal moving slide 304 to slide back and forth on the longitudinal support guide rail 301. This allows it to work with the transverse moving mechanism 4 to drive the lifting and cutting mechanism 5 to freely slide and adjust its longitudinal and transverse positions, thereby enabling precise cutting of the metal sheet 9 according to the programmed program.

[0030] Regarding the lateral movement mechanism 4, refer to... Figures 1-11A transverse moving mechanism 4 is fixedly connected between the two sets of longitudinal moving mechanisms 3. The transverse moving mechanism 4 includes a support beam 401 fixed between the two sets of longitudinal moving mechanisms 3. A transverse limiting slide rail 402 is fixedly connected to the top and rear end of the support beam 401. A second fixed rack 403 is also fixedly connected to the rear end of the support beam 401. A transverse moving slide 404 is slidably mounted on the support beam 401. A second servo motor 405 is fixedly mounted on the top and rear end of the transverse moving slide 404. A second drive gear 406 that meshes with the second fixed rack 403 is fixedly mounted on the output end of the second servo motor 405. The transverse moving mechanism 4 can drive the lifting and cutting mechanism 5 to move laterally. During operation, the second servo motor 405 can drive the second drive gear 406 to rotate synchronously through its output shaft. Since the second drive gear 406 meshes with the second fixed rack 403, the entire transverse moving slide 404 can slide left and right on the support beam 401, thereby cooperating with the longitudinal moving mechanism 3 to complete the precise cutting of the metal sheet 9.

[0031] Regarding the lifting and cutting mechanism 5, please refer to... Figures 1-10 A lifting and cutting mechanism 5 for cutting metal sheets 9 is installed on the transverse moving mechanism 4. The lifting and cutting mechanism 5 includes a lifting transmission rack 501 slidably mounted on the front end of the transverse moving slide 404. A first mounting base 502 is fixedly connected to the top front end of the transverse moving slide 404. A third servo motor 503 is mounted on the first mounting base 502. A third drive gear 504 meshing with the lifting transmission rack 501 is fixedly mounted on the output end of the third servo motor 503. A laser cutting component 505 is fixedly mounted on the front end of the lifting transmission rack 501. As the main cutting component, the lifting and cutting mechanism 5, when in operation, allows the third servo motor 503 to drive the first servo motor 501 through its output shaft. The three drive gears 504 rotate, which in turn drives the lifting transmission rack 501 and the laser cutting component 505 to move up and down. During the cutting process, the third servo motor 503 drives the laser cutting component 505 to move down, so that the bottom end of the laser cutting component 505 is close to the metal plate 9. During the processing, the laser cutting component 505 emits a high-temperature laser and irradiates the metal plate 9, causing it to melt rapidly. At the same time, gas is ejected from its bottom nozzle to blow away the molten material, thus completing the cutting process. With the further drive of the longitudinal moving mechanism 3 and the transverse moving mechanism 4, cuts of any shape can be cut on the metal plate 9.

[0032] Regarding the automatic feeding mechanism 6, please refer to... Figures 12-16The cutting platform 1 has an automatic feeding mechanism 6 at its rear end. A plate positioning mechanism 7 for pre-positioning metal sheet 9 is slidably mounted on one side of the top of the automatic feeding mechanism 6. The automatic feeding mechanism 6 can automatically feed the metal sheet 9 to the designated processing position on the top of the plate support mechanism 2 by flipping. The automatic feeding mechanism 6 includes a support platform 601 located at the rear end of the cutting platform 1. Two symmetrically arranged second mounting seats 602 are fixedly connected to the front end of the top of the support platform 601. An L-shaped rotating arm 603 is rotatably connected between the two second mounting seats 602. A fourth servo motor 604 for driving the L-shaped rotating arm 603 to rotate is mounted on one of the second mounting seats 602. A negative pressure adsorption assembly 605 is fixedly mounted at the rear end of the L-shaped rotating arm 603. A cavity 606 is provided in the middle of the negative pressure adsorption assembly 605. Multiple vacuum adsorption points communicating with the cavity 606 are opened on the top of the negative pressure adsorption assembly 605. A silicone pad 608 is fixedly connected to the top of the negative pressure adsorption component 605, and a vacuum pump 609 communicating with the cavity 606 is fixedly installed at the bottom of the negative pressure adsorption component 605. The automatic feeding mechanism 6 is mainly used for the automatic rotational feeding of the metal sheet 9. During operation, the metal sheet 9 can be placed horizontally on the top of the support platform 601 and positioned directly above the negative pressure adsorption component 605. After the metal sheet 9 is placed and positioned, the vacuum pump 609 is started, thereby generating negative pressure suction in the cavity 606 and multiple vacuum adsorption holes 607. The metal sheet 9 will be tightly adsorbed and fixed on the silicone pad 608. At this time, the fourth servo motor 604 is started, which drives the L-shaped rotating arm 603 to rotate 180 degrees, thereby automatically placing the metal sheet 9 on the top of the negative pressure adsorption component 605 at the designated position on the top of the sheet support mechanism 2, thus completing the precise automatic feeding operation.

[0033] In this embodiment, two limiting grooves 610 are provided on one side of the top of the support platform 601. The two limiting grooves 610 can guide and limit the sliding adjustment of the plate positioning mechanism 7.

[0034] Regarding the plate positioning mechanism 7, please refer to... Figures 12-14The plate positioning mechanism 7 includes a limiting angle steel 701 slidably installed on one side of the top of the support platform 601. Two T-shaped limiting bolts 702 pass through the limiting angle steel 701, and the bottom ends of the two T-shaped limiting bolts 702 slide in the corresponding limiting grooves 610. Each of the two T-shaped limiting bolts 702 is threaded with a fixing nut 703. An auxiliary limiting component 704 is also attached to the limiting angle steel 701, and a locking bolt 705 is threaded on the auxiliary limiting component 704. The plate positioning mechanism 7 is mainly used for auxiliary positioning of the metal plate 9. During processing, the positions of the limiting angle steel 701 and the auxiliary limiting component 704 can be pre-adjusted according to the size of the metal plate 9. After the adjustment is completed, the fixing nuts 703 and the locking bolts 705 are locked respectively to fix their positions. Finally, the two adjacent sides of the metal plate 9 to be processed are placed close to the limiting angle steel 701 and the auxiliary limiting component 704 to complete the precise pre-positioning of the metal plate 9.

[0035] The working principle of this embodiment is as follows: During processing, the positions of the limiting angle steel 701 and the auxiliary limiting component 704 are pre-adjusted according to the size of the metal plate 9. After the adjustment is completed, the fixing nut 703 and the locking bolt 705 are locked respectively to fix their positions. Then, the adjacent sides of the metal sheet 9 to be processed are respectively attached to the limiting angle steel 701 and the auxiliary limiting component 704, and positioned directly above the negative pressure adsorption component 605. After the metal sheet 9 is placed and positioned, the vacuum pump 609 is started, which generates negative pressure suction in the cavity 606 and multiple vacuum adsorption holes 607. The metal sheet 9 will be tightly adsorbed and fixed on the silicone pad 608. At this time, the fourth servo motor 604 is started. The fourth servo motor 604 will drive the L-shaped rotating arm 603 to rotate 180 degrees, so that the metal sheet 9 on the top of the negative pressure adsorption component 605 can be automatically placed at the designated position on the top of the sheet support mechanism 2, thereby completing the precise automatic feeding operation. After the metal sheet 9 is placed in place, the longitudinal moving mechanism 3 can drive the transverse moving mechanism 4 and the lifting cutting mechanism 5 to move longitudinally and horizontally. The transverse moving mechanism 4 can drive the lifting cutting mechanism 5 to move laterally. The third servo motor 503 will drive the laser cutting component 505 to move downward, so that the bottom end of the laser cutting component 505 is close to the metal sheet 9. During the processing, the laser cutting component 505 will emit a high-temperature laser and irradiate the metal sheet 9, causing it to melt rapidly. At the same time, gas will be ejected from its bottom nozzle to blow away the molten material, thereby completing the cutting process. With the further drive of the longitudinal moving mechanism 3 and the transverse moving mechanism 4, cuts of any shape can be cut on the metal sheet 9. Waste generated during the cutting process will be collected in the waste collection trough 8. After the cutting is completed, the processed metal sheet 9 can be removed from the sheet support mechanism 2.
