[0014] A control method for a five-axis three-linkage laser cutting machine, the control method comprising:

[0015] Place the object on the thumbwheel mounting tube and make its bottom fit on the thumbwheel mechanism;

[0016] Each set of card plates is clamped onto the object from different directions, and the card plates are used to fix the object;

[0017] Start the laser cutting module and use the laser cutting module to cut the object;

[0018] When the horizontal cutting angle of the object needs to be adjusted, the second electric turntable is started, and the second electric turntable drives the dial wheel mounting cylinder to rotate, and then the dial wheel mounting cylinder drives the object to rotate in the horizontal direction, so as to adjust the angle of the object in the horizontal direction;

[0021] The beneficial effects of the present invention are:

[0022] 1. The second electric turntable and the dial mechanism can drive the object to rotate horizontally and vertically at the same time, so that there will be no dead angle in the cutting of the object. This solves the problem that the traditional laser cutting machine cannot cut the joint between the object and the fixing mechanism during cutting, thereby improving the smoothness of laser cutting. And when the object is rotating, the surrounding card plates can limit the object to prevent it from falling. At the same time, the retractable characteristics of the gas spring can be used to fix the object regardless of its shape and size through the card plate, thereby improving its compatibility.

[0023] 2. The dial mechanism is composed of several groups of toggle teeth distributed in a ring array to perform the toggle work of the object. Since the cross-section of the toggle teeth is a fan-shaped structure, no matter what the shape of the object is, the top of the toggle teeth can better fit the surface of the object, thereby improving the smoothness of the object's toggle work. When the object is stationary, not only can the object be fixed by several groups of anti-slip bumps caused by the friction force on the surface of the toggle teeth, but the object can also be supported from both sides of the bottom of the object by two adjacent groups of side slides. Because of the several groups of corner slots arranged at equal intervals on the side slides, no matter what the shape of the object is, its corners can find a corresponding group of corner slots to plug in, avoiding the bottom of the object from being suspended in the air, and improving the stability of the object when it is stationary.

[0024] 3. The present invention can not only cut and fix block-shaped objects, but also fix plate-shaped objects through the support unit, enriching the functionality of the laser cutting machine. And the top of the support rod used for support is composed of several groups of support teeth with conical cross-sections, so the heat generated by laser cutting can be quickly dissipated from the bottom of the plate-shaped object, thereby improving the heat dissipation effect.

[0025] 4. When the cutting angle of the object needs to be adjusted, the second electric turntable and the dial mechanism can simultaneously meet the object's horizontal and vertical angle adjustment to avoid cutting dead angles. There is no need to stop the laser cutting machine as a whole and then adjust it manually, which improves the smoothness of the cutting work.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] An embodiment of the present invention provides a five-axis three-linkage laser cutting machine, including a chassis 100, a working frame platform 300, and a support unit 400. Exemplarily, as Figure 1 、 Figure 2 and Figure 3 shown, a five-axis cutting module is provided on the chassis 100. The five-axis cutting module includes a first electric slide 110 and a second electric slide 120. The second electric slide 120 is disposed at the output end of the first electric slide 110. The included angle between the output direction of the second electric slide 120 and the output direction of the first electric slide 110 is 90°. A cutting unit 200 is slidably connected to the output end of the second electric slide 120. The cutting unit 200 includes an electric lifting seat 210. A first electric turntable 220 is provided at the output end of the electric lifting seat 210. A vertical rotating seat 230 is provided at the output end of the first electric turntable 220. A laser cutting head 240 is provided at the output end of the vertical rotating seat 230.

[0045] First, the first electric slide 110 and the second electric slide 120 are used to realize the horizontal movement of the laser cutting head 240 in the length direction and the width direction of the chassis 100. Then, the electric lifting seat 210 is used to realize the vertical lifting movement of the laser cutting head 240. The first electric turntable 220 and the vertical rotating seat 230 are respectively used to realize the rotation of the laser cutting head 240 in the horizontal direction and the vertical direction. Thus, the requirements of five-axis three-linkage are met, and the flexibility of the laser cutting head 240 is improved.

[0046] The working frame platform 300 is fixedly installed on the chassis 100. The top view cross-section of the working frame platform 300 is a rectangular frame structure, and a support frame platform 310 is provided at the top peripheral edge of the central through hole of the working frame platform 300.

[0047] The housing of the support unit 400 is movably installed on the support frame platform 310, and the outer walls of the four sides of the housing of the support unit 400 are movably attached to the inner walls of the four sides of the support frame platform 310.

[0048] When a plate-like object needs to be cut, the support unit 400 is placed on the support frame platform 310, and the plate-like object can be directly placed on the support unit 400, which enriches the functionality of the laser cutting machine.

[0049] The top of the chassis 100 is provided with an azimuth adjustment unit 500, and the top of the azimuth adjustment unit 500 can movably penetrate into the central through hole of the working frame table 300. The azimuth adjustment unit 500 is used to adjust the angle or azimuth of the block-shaped object during the cutting operation.

[0050] On the inner wall of the central through hole of the working frame table 300, a side limit unit 600 is provided. The side limit unit 600 is used to limit the block-shaped object.

[0051] The support unit 400 includes a support frame body 410. Exemplarily, as Figure 4 shown, the top view cross-section of the support frame body 410 is a rectangular frame structure, and the support frame body 410 is movably installed on the support frame table 310, and the outer walls of the four sides of the support frame body 410 are respectively in movable contact with the inner walls of the four sides of the support frame table 310. A number of groups of support rods 420 are evenly distributed in the central through hole of the support frame body 410.

[0052] The support rod 420 includes a support rod base 421 and a number of groups of support teeth 423. Exemplarily, as Figure 5 、 Figure 6 and Figure 7 shown, both ends of the support rod base 421 are respectively fixedly installed on the inner walls of both sides of the central through hole of the support frame body 410, and a number of groups of ventilation holes 422 are evenly arranged on the outer walls of both sides of the support rod base 421. A number of groups of the support teeth 423 are evenly arranged on the top of the support rod base 421, and the cross-section of the support teeth 423 is a conical structure. Two groups of air inlets 424 are symmetrically opened on the inclined outer walls on both sides of the support teeth 423, the bottom of the air inlet 424 is communicated with an air outlet channel 425, and the other end of the air outlet channel 425 is communicated with the cavity of the support rod base 421. And the inner diameter of the air outlet channel 425 near the air inlet 424 is larger than the other end.

[0053] When it is necessary to cut a plate-like object, firstly, the support frame body 410 is clamped on the support frame platform 310, and the plate-like object is placed on the top of each group of support rods 420 arranged at equal intervals. Since the cross-section of the support teeth 423 is a conical structure, when cutting, the heat generated by the operation of the laser cutting head 240 will move downward to the gap between two adjacent groups of support teeth 423, and enter the cavity of the support rod base 421 through the air inlet 424 and the air outlet channel 425, and finally be discharged through the vent 422. The problem of poor heat dissipation effect caused by the solid structure of the bottom support part of the traditional laser cutting machine is solved, and since the diameter of the air outlet channel 425 near the air inlet 424 is larger than the other end, when the heat enters the air outlet channel 425, its movement speed will be accelerated, thereby accelerating the heat dissipation speed.

[0054] The azimuth adjustment unit 500 includes an elastic lifting mechanism, a dial mounting cylinder 510 and a dial mechanism 540. For example, Figure 8 , Figure 9 and Figure 10 As shown, a bottom frame top groove 501 is provided on the top of the bottom frame 100, and a side sliding groove 503 is provided on the side wall of the bottom frame top groove 501. The elastic lifting mechanism includes a return spring 502, one end of which is mounted on the bottom of the bottom frame top groove 501, and a spring pressure block 504 is mounted on the other end, a side slider 505 is mounted on the side wall of the spring pressure block 504, and the other end of the side slider 505 is slidably connected in the side sliding groove 503. A second electric turntable 506 is mounted on the spring pressure block 504, one end of the thumbwheel mounting cylinder 510 is mounted on the second electric turntable 506, and the other end extends above the bottom frame 100. A thumbwheel transmission mechanism is provided in the thumbwheel mounting cylinder 510, and the thumbwheel transmission mechanism includes a servo motor 520 and a thumbwheel rotating rod 530, and a transmission gear 521 is transmission-connected to the output end of the servo motor 520. The dial lever 530 is located directly above the transmission gear 521, and a driven gear 550 is sleeved on the dial lever 530. The driven gear 550 is meshedly connected to the transmission gear 521. The dial mechanism 540 is sleeved on the dial lever 530, and the top of the dial mechanism 540 extends to the outside of the dial mounting cylinder 510.

[0055] The dial mechanism 540 includes a dial center plate 541 and a plurality of groups of dial teeth 542. Figure 11As shown, the dial center disk 541 is sleeved on the dial rotating rod 530, and the top of the dial center disk 541 extends to the top of the dial mounting tube 510. Several groups of the toggle teeth 542 are distributed in a ring array on the side wall of the dial center disk 541. The cross section of the toggle teeth 542 is a fan-shaped structure, and two groups of side slide slopes 544 are symmetrically arranged on the two side walls of the toggle teeth 542, one end of the side slide slope 544 is fixedly connected to the top edge of the toggle teeth 542, and the other end extends to the side wall of the dial center disk 541. Several groups of corner slots 545 are arranged at equal intervals on the side slide slope 544, and both ends of the corner slots 545 are open structures. Several groups of anti-slip bumps 543 are evenly distributed on the surface of the toggle teeth 542.

[0056] The side limit unit 600 includes four sets of clamping plates 620. For example, Figure 12 , Figure 13 and Figure 14 As shown, the top view cross-section of the central through hole of the working frame 300 is a rectangular structure, and a group of frame inner grooves 601 are provided on the center lines of the inner walls around the central through hole of the working frame 300, and a gas spring 610 is fixedly installed in the frame inner groove 601. The output end of the gas spring 610 extends into the central through hole of the working frame 300 and is fixedly connected to one group of card plates 620. A groove is provided on one side wall of the card plate 620 away from the gas spring 610, and the side section and top view cross section of the groove are both fan-shaped structures, and a card plate front groove 630 is provided at the center of the groove. A rotating ball 640 is rotatably connected in the card plate front groove 630, and a side wall of the rotating ball 640 extends to the outside of the card plate front groove 630.

[0057] When cutting a block-shaped object or a special-shaped object, the object is first placed on the dial mounting cylinder 510 so that its bottom is attached to the dial mechanism 540. Then, each group of card plates 620 is attached to the object from different directions, and it is ensured that the rotating balls 640 are all attached to the object, so that the card plates 620 have a fixing effect on the object. Since the top view section and the side section of the card plates 620 are both fan-shaped ring structures, the protection of the card plates 620 on the object is expanded, and the risk of the object shaking or falling during cutting is reduced. In addition, by using each group of gas springs 610 that can perform telescopic movement, when the object is adjusted in angle or direction, no matter what the shape and size of the object is, it can be attached to each group of card plates 620. When it is necessary to adjust the angle of the object in the horizontal direction, the second electric turntable 506 is directly controlled to drive the dial mounting cylinder 510 to rotate, and then the dial mounting cylinder 510 drives the object to rotate. When the object needs to be adjusted in the vertical direction, the dial transmission mechanism is activated, and the dial mechanism 540 is driven by the dial transmission mechanism, and the dial mechanism 540 then moves the object, so that the object can be rotated in the vertical direction. Because the rotating ball 640 in the front groove 630 of the card plate can rotate in any direction, when the rotating ball 640 is attached to the object, as the object rotates, the rotating ball 640 can further push the object, thereby increasing the smoothness of the object's rotation.

[0058] The second electric turntable 506 and the dial mechanism 540 can drive the object to rotate in the horizontal direction and the vertical direction at the same time, so that there will be no dead angle in the cutting of the object. The problem that the traditional laser cutting machine cannot cut the joint between the object and the fixing mechanism during cutting is solved, thereby improving the smoothness of the laser cutting work. And when the object is rotating, the surrounding clamping plates 620 can limit the object to prevent it from falling. At the same time, the retractable characteristics of the gas spring 610 are utilized, so that the object can be fixed by the clamping plate 620 regardless of its shape and size, thereby improving its compatibility.

[0059] The dial mechanism 540 is composed of a plurality of groups of toggle teeth 542 distributed in a ring array to perform the toggle operation of the object. Since the cross section of the toggle teeth 542 is a fan-shaped structure, the top of the toggle teeth 542 can better fit the surface of the object regardless of the shape of the object, thereby improving the smoothness of the object toggle operation. When the object is stationary, not only can the object be fixed by the plurality of groups of anti-skid protrusions 543 caused by the friction force on the surface of the toggle teeth 542, but also the object can be supported from both sides of the bottom of the object by two adjacent groups of side slides 544. Moreover, because of the plurality of groups of corner slots 545 arranged at equal intervals on the side slides 544, no matter what the shape of the object is, its corner can find a corresponding group of corner slots 545 to be connected, thereby preventing the bottom of the object from being suspended in the air and improving the stability of the object when it is stationary.

[0060] Based on the above five-axis three-linkage laser cutting machine, the embodiment of the present invention further proposes a control method for the five-axis three-linkage laser cutting machine. Exemplarily, the control method includes:

[0061] Place the object on the thumbwheel mounting tube and make its bottom fit on the thumbwheel mechanism;

[0062] Each set of card plates is clamped onto the object from different directions, and the card plates are used to fix the object;

[0063] Specifically, since the top and side cross-sections of the clamping plate are both fan-shaped structures, the protection of the clamping plate on the object is expanded, reducing the risk of the object shaking or falling during cutting. And by using each group of gas springs that can perform telescopic movement, when the object is adjusted in angle or orientation, no matter what the shape and size of the object is, it can be simply clamped with each group of clamping plates;

[0064] Start the laser cutting module and use the laser cutting module to cut the object;

[0065] When the horizontal cutting angle of the object needs to be adjusted, the second electric turntable is started, the second electric turntable drives the thumbwheel mounting cylinder to rotate, and then the thumbwheel mounting cylinder drives the object to rotate horizontally;

[0066] When the vertical cutting angle of the object needs to be adjusted, the thumbwheel transmission mechanism is started, the thumbwheel mechanism is driven by the thumbwheel transmission mechanism, and then the thumbwheel mechanism shifts the object, so that the object can be rotated in the vertical direction;

[0067] After the cutting is completed, the groups of clamping plates are moved to separate them from the object, and the object is taken out from the dial wheel mounting cylinder, and the cutting work is completed.

[0068] When the cutting angle of the object needs to be adjusted, the second electric turntable and the dial mechanism can simultaneously meet the object's horizontal and vertical angle adjustments to avoid cutting dead angles. There is no need to stop the laser cutting machine as a whole and then adjust it manually, which improves the smoothness of the cutting work.

[0069] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
