A dual-station robotic automatic flame cutting device

Abstract

This invention relates to the field of cutting equipment technology, specifically a dual-station robotic automatic flame cutting device, including a base and a flame cutting head. A lateral moving component is movably mounted on the top of the base, driving the lateral movement of the flame cutting head. A slag collection component collects the slag, and the slag collection frame within this component moves with the flame cutting head to collect the slag. During the movement of the slag collection frame, two torsion rods and a torsion-limiting slide bar move together, preventing the sealing flap from rotating downwards. This prevents the slag inside the slag collection frame from spilling from the bottom. When the torsion-limiting slide bar slides along the path groove into the fan-shaped groove, the gravity of the sealing flap causes the torsion rods and the torsion-limiting slide bar to rotate downwards, opening the bottom of the slag collection frame. The slag inside then falls through the bottom opening into the scooping tank, thus automatically cleaning the inside of the slag collection frame. This device is highly practical.

Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to a dual-station robotic automatic flame cutting device. Background Technology

[0002] Commonly used flame cutting gases include acetylene, propane, liquefied petroleum gas, coke oven gas, and natural gas. According to the authorization announcement number of Chinese patent CN115770923B, an alloy flame cutting processing device is disclosed. After the tightening bolt is loosened, the vertical hammer rod can be hammered downward to open the two semi-circular cylinder plates, preventing the two semi-circular cylinder plates from being stuck together by the molten alloy slag during welding, which would make them difficult to open and hinder the cleaning of alloy slag in the slag cylinder. However, after the above device is used, the slag cylinder still needs to be cleaned manually, which limits its practicality. In addition, there is a gap between the top of the slag cylinder and the object being cut, and some cutting slag can easily splash out from the gap, resulting in an unsatisfactory collection effect.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, a slag-collecting component is used to collect slag. The slag-collecting frame in the slag-collecting component can move with the flame cutting head to collect slag. During the movement of the slag-collecting frame, two torsion rods and a torsion-limiting slide bar move together, preventing the sealing flap from rotating downwards. As a result, the slag inside the slag-collecting frame will not fall from the bottom of the frame. When the torsion-limiting slide bar slides into the fan-shaped groove along the path groove, the gravity of the sealing flap causes the torsion rods and the torsion-limiting slide bar to rotate downwards, opening the bottom of the slag-collecting frame. The slag inside the frame then falls into the scooping groove through the bottom opening, thus automatically cleaning the inside of the slag-collecting frame. This invention is highly practical.

[0020] 2. In this invention, the magnetic attraction between the magnetic blocks and the bottom of the steel plate causes multiple magnetic blocks to move upward. The upward movement of the multiple magnetic blocks drives the joint-stopping frame to slide upward along the outer wall of the slag collection frame via the connecting strip, so that the top of the joint-stopping frame fits into the bottom of the steel plate, and the outer walls of the two rolling rods just abut against the bottom of the steel plate. Therefore, under the fitting effect between the top of the joint-stopping frame and the bottom of the steel plate, there will be no gap between the top of the slag collection frame and the bottom of the steel plate, so that the slag can be better collected inside the slag collection frame.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1 - Figure 8 The technical solution provided by the present invention specifically includes the following embodiments:

[0032] Example 1: A dual-station robotic automatic flame cutting device includes a base 1 and a flame cutting head 6;

[0033] A transverse moving component 2 is movably mounted on the top of the base 1. This transverse moving component 2 drives the transverse movement of the flame cutting head 6. The transverse moving component 2 includes two transverse moving vertical plates 201 distributed front to back. The tops of the two transverse moving vertical plates 201 are connected to a transverse moving horizontal plate 202. A sliding groove 203 is formed through the top of the transverse moving horizontal plate 202. A longitudinal moving component 3 is slidably mounted inside the sliding groove 203. Linear sliders 204 are fixedly mounted on the bottom of each transverse moving vertical plate 201. Two linear guide rails 2010 distributed front to back are fixedly mounted on the top of the base 1. The outer walls of the two linear guide rails 2010 are respectively connected to the two linear sliders 204. The inner wall is slidably connected. Two linear sliders 204 are fixedly mounted on their adjacent sides with levers 205. The two levers 205 are connected to a ball sleeve 206 at their adjacent ends. A first servo motor 207 is fixedly mounted on one end of the top of the base 1. A ball screw 208 is fixedly mounted on the output shaft end of the first servo motor 207 through a coupling. The ball screw 208 passes through the interior of the ball sleeve 206, and the ball screw 208 and the ball sleeve 206 are connected by a threaded engagement. A bearing seat 209 is fixedly mounted on the top of the base 1 away from the first servo motor 207. The inner wall of the bearing seat 209 is rotatably connected to the outer wall of the ball screw 208.

[0034] The transverse moving component 2 is internally equipped with a longitudinal moving component 3, which is used to drive the longitudinal movement of the flame cutting head 6. The longitudinal moving component 3 includes a longitudinal slider 301 that is slidably installed inside the slide groove 203. The flame cutting head 6 is fixedly installed inside the longitudinal slider 301. A longitudinal travel motor 302 is fixedly installed on the top of the longitudinal slider 301. A traveling gear 303 is fixedly installed on the output shaft of the longitudinal travel motor 302. A rack 304 is fixedly installed on the top of the transverse moving plate 202. The rack 304 is located on the opening side of the slide groove 203 and is located at the bottom of the traveling gear 303. The traveling gear 303 and the rack 304 mesh with each other.

[0035] In this embodiment, the first servo motor 207 is activated to drive the ball screw 208 to rotate. The bearing housing 209 rotates, causing the ball sleeve 206 and the two levers 205 connected to the ball sleeve 206 to move along the axial direction of the ball screw 208. The movement of the two levers 205 causes the two linear sliders 204 to slide along the two linear guide rails 2010, and also causes the two transverse moving vertical plates 201 and the transverse moving horizontal plates 202 connected to the two transverse moving vertical plates 201 to move together. The movement of the transverse moving horizontal plates 202 further drives the longitudinal slider 301, the flame cutting head 6, and the slag collection component 4 to move together through the slide groove 203, thus moving the flame cutting head... When the head 6 moves to the cutting position, the longitudinal slider 301 is initially located at one end of the inner side of the groove 203. When the flame cutting head 6 reaches the cutting position, the flame cutting head 6 is turned on and sprays cutting flames to cut the steel plate. At the same time, the output shaft of the longitudinal travel motor 302 drives the traveling gear 303 to rotate. The traveling gear 303 meshes with the rack 304, so the rotation of the traveling gear 303 will roll along the top of the rack 304. Furthermore, the longitudinal travel motor 302 drives the longitudinal slider 301 to move along one end of the groove 203 to the other end. The movement of the longitudinal slider 301 will further drive the flame cutting head 6 to move, performing linear cutting on the steel plate.

[0036] In embodiment 2, a slag-collecting component 4 is movably installed inside the transverse moving component 2. The slag-collecting component 4 is used for slag collection. The slag-collecting component 4 includes two guide rail frames 401 fixedly installed between the front and rear transverse moving vertical plates 201. The two guide rail frames 401 are distributed left and right. A path groove 402 is opened on the side of the two guide rail frames 401 that is close to each other. A fan-shaped groove 403 is opened at both ends of the path groove 402. A slag-collecting frame 404 is movably installed between the two guide rail frames 401. Two torsion rods 405 are rotatably installed inside the slag-collecting frame 404. A sealing flap 406 is fixedly installed on the outer wall of each torsion rod 405. Plate 406 is symmetrically distributed about the central axis of slag collection frame 404. Both ends of torsion bar 405 are fixedly installed with limiting torsion strips 407. The limiting torsion strips 407 slide inside the path groove 402. A soft rope 4012 is fixedly installed at the rear of slag collection frame 404. The end of the soft rope 4012 away from slag collection frame 404 is fixedly connected to the front of longitudinal slider 301. The soft rope 4012 moves through the transverse moving plate 202 and extends into the interior of the slide groove 203. Two vertically distributed support rollers 4013 are fixedly installed on the opposite sides of the two transverse moving vertical plates 201. The soft rope 4012 is wrapped around the periphery of each support roller 4013.

[0037] A joint-stop frame 4041 is slidably installed on the upper part of the outer wall of the slag collection frame 404. Rolling rods 408 are rotatably installed on the front and rear parts of the magnetic block 4010. Connecting strips 409 are fixedly installed on the left and right parts of the joint-stop frame 4041. Multiple magnetic blocks 4010 distributed at equal distances in front and behind are fixedly installed on the top of the connecting strips 409.

[0038] Two left-right distributed support bars 4014 are fixedly installed at the top front end and top rear end of the base 1. The top of the two left-right distributed support bars 4014 is fixedly installed with a ladle 4015. The height of the ladle 4015 is adapted to the height of the slag collection frame 404.

[0039] In this embodiment, during the linear cutting process of the flame cutting head 6, the longitudinal slider 301 moves and pulls the soft rope 4012. Supported by multiple support rollers 4013, the soft rope 4012 pulls the slag collection frame 404 along the bottom of the steel plate, moving together with the longitudinal slider 301 to collect the slag generated in the cut. Initially, due to the sealing effect of the two sealing flaps 406 on the bottom of the slag collection frame 404, the slag falling into the slag collection frame 404 will not fall. Furthermore, during the movement of the slag collection frame 404 along the bottom of the steel plate, multiple magnetic blocks 4... The magnetic attraction between 010 and the bottom of the steel plate causes multiple magnetic blocks 4010 to move upward. The upward movement of multiple magnetic blocks 4010 drives the joint stop frame 4041 to slide upward along the outer wall of the slag collection frame 404 via the connecting strip 409, so that the top of the joint stop frame 4041 fits against the bottom of the steel plate, and the outer walls of the two rolling rods 408 just abut against the bottom of the steel plate. Therefore, under the fitting action between the top of the joint stop frame 4041 and the bottom of the steel plate, there is no gap between the top of the slag collection frame 404 and the bottom of the steel plate, so that the slag can be better collected inside the slag collection frame 404.

[0040] It should be noted that during the movement of the slag collection frame 404, the two torsion bars 405 and the torsion limiting slide bar 407 move together. Since the torsion limiting slide bar 407 always slides along the inner wall of the path groove 402, it will not twist. In other words, the torsion bars 405 will not twist either. Therefore, the sealing flap 406, which is fixedly connected to the outer wall of the torsion bars 405, will not rotate downwards. As a result, the slag inside the slag collection frame 404 will not spill from the bottom of the slag collection frame 404. When the torsion limiting slide bar 407 slides into the inside of the fan-shaped groove 403 along the path groove 402, the slag collection frame 404 moves. The slag is moved to the top of a scooping trough 4015. At the same time, the gravity of the sealing flap 406 causes the torsion rod 405 and the torsion limiting slide 407 to rotate downwards until the bottom of the torsion limiting slide 407 contacts the bottom wall of the fan-shaped groove 403. The sealing flap 406 rotates downwards, causing the bottom of the slag collection frame 404 to be opened. The slag inside the slag collection frame 404 falls into the scooping trough 4015 through the bottom opening, thus automatically cleaning the inside of the slag collection frame 404. Since the slag collection frame 404 pours the slag into the scooping trough 4015, it does not cause pollution inside the device.

[0041] Furthermore, a return spring 4011 is fixedly installed between the front of the slag collection frame 404 and the back of a horizontally moving vertical plate 201 directly opposite it. During the linear cutting of the flame cutting head 6, the longitudinal slider 301 moves and pulls the soft rope 4012. Under the support of multiple support rollers 4013, the soft rope 4012 pulls the slag collection frame 404 along the bottom of the steel plate and moves together with the longitudinal slider 301, causing the return spring 4011 to be stretched and stored. When the cutting is completed, the output shaft of the longitudinal travel motor 302 drives the traveling gear 303 to rotate in the opposite direction, causing the traveling gear 303 to move along the tooth... The top of bar 304 rolls in the opposite direction, causing the longitudinal slider 301 and the flame cutting head 6 to reset, thereby releasing the tension on the soft rope 4012. Under the support of multiple support rollers 4013, the tension on the slag collection frame 404 is released, causing the reset spring 4011 to rebound and pull the slag collection frame 404 back to its original position along with the longitudinal slider 301. At the same time, the rebound force of the reset spring 4011 on the slag collection frame 404 is transmitted to the soft rope 4012 through the slag collection frame 404, which keeps the soft rope 4012 taut and prevents it from bending or knotting.

[0042] In embodiment 3, the top of the base 1 is provided with a support component 5, which is used to support the object to be cut. The support component 5 includes two left and right distributed light rods 501. Both light rods 501 are fixedly installed on the front and rear support bars 4014. Two adjusting blocks 502 are slidably installed on the outer wall of each light rod 501. Two left and right distributed triangular plates 503 are fixedly installed on the top of each adjusting block 502. A support plate 504 is fixedly installed on the top of each of the two left and right distributed triangular plates 503.

[0043] A second servo motor 505 is fixedly installed on the lower outer side of one of the light rods 501. The output shaft of the second servo motor 505 moves through the horizontally moving vertical plate 201. The end of the output shaft of the second servo motor 505 is fixedly installed with a positive and negative lead screw 506 through a coupling. The outer thread of the positive and negative lead screw 506 is connected to two internal thread blocks 507 distributed in the front and back. The top of each internal thread block 507 is provided with a slot 508. The two internal thread blocks 507 are respectively located at the positions of the two adjusting blocks 502, and the inner wall of the slot 508 is slidably connected to the outer wall of the adjusting block 502.

[0044] In this embodiment, the steel plate to be cut is gripped by an external robotic arm and placed on top of two support plates 504, as shown in the attached diagram. Figure 1 The state shown is sufficient. Furthermore, the distance between the two support plates 504 at the front and rear of this device is adjustable to facilitate the support and cutting of steel plates of different widths. When adjustment is needed, the second servo motor 505 is activated, causing its output shaft to drive the positive and negative lead screws 506 to rotate. Due to the positive and negative thread setting of the positive and negative lead screws 506, during rotation, the two internal thread blocks 507 move closer to or further away from each other. The movement of the internal thread blocks 507 further drives the triangular plate 503 along with the support plates 504 via the adjusting block 502, causing the two support plates 504 at the front and rear to move together, thus adjusting the distance to meet the support requirements of steel plates of different widths and improving the flexibility of the device.

[0045] This solution describes a dual-station robotic automatic flame cutting device. During operation, the external robotic arm grips the steel plate to be cut and places it on top of two support plates 504, as shown in the attached diagram. Figure 1The state shown is sufficient. In this device, the distance between the two support plates 504 at the front and rear is adjustable to facilitate the support and cutting of steel plates of different widths. When adjustment is required, the second servo motor 505 is started, and its output shaft drives the positive and negative screws 506 to rotate. Due to the positive and negative threads of the positive and negative screws 506, the two internal thread blocks 507 move closer to each other or further away from each other during the rotation of the positive and negative screws 506. The movement of the internal thread blocks 507 further drives the triangular plate 503 together with the support plates 504 through the adjusting block 502, so that the two support plates 504 at the front and rear move together to realize the adjustment of the distance, meet the support requirements of steel plates of different widths, and improve the flexibility of the device.

[0046] After the steel plate is placed on top of the two support plates 504, the first servo motor 207 is started, and its output shaft drives the ball screw 208 to rotate. The bearing seat 209 rotates, causing the ball sleeve 206 and the two levers 205 connected to the ball sleeve 206 to move along the axial direction of the ball screw 208. The movement of the two levers 205 causes the two linear sliders 204 to slide along the two linear guide rails 2010, and also causes the two transverse moving vertical plates 201 and the transverse moving horizontal plates 202 connected to the two transverse moving vertical plates 201 to move together. The movement of the transverse moving horizontal plates 202 further drives the longitudinal slider 301, the flame cutting head 6 and the slag collection component 4 to move together through the slide groove 203. After the flame cutting head 6 is moved to the cutting position, the first servo motor 207 is turned off.

[0047] Initially, the longitudinal slider 301 is located at one end of the inner side of the groove 203. When the flame cutting head 6 reaches the cutting position, the flame cutting head 6 is turned on and sprays cutting flames to cut the steel plate. At the same time, the output shaft of the longitudinal travel motor 302 drives the traveling gear 303 to rotate. The traveling gear 303 meshes with the rack 304, so the rotation of the traveling gear 303 will roll along the top of the rack 304. Furthermore, the longitudinal travel motor 302 drives the longitudinal slider 301 to move from one end of the groove 203 to the other end. The movement of the longitudinal slider 301 will further drive the flame cutting head 6 to move, and perform linear cutting on the steel plate.

[0048] During the linear cutting process of the flame cutting head 6, the longitudinal slider 301 moves and pulls the soft rope 4012. Supported by multiple support rollers 4013, the soft rope 4012 pulls the slag collection frame 404 along the bottom of the steel plate, moving together with the longitudinal slider 301 to collect the slag generated in the cut. Initially, due to the sealing effect of the two sealing flaps 406 on the bottom of the slag collection frame 404, the slag falling into the slag collection frame 404 will not fall. Furthermore, as the slag collection frame 404 moves along the bottom of the steel plate, multiple magnetic blocks 4010 and... The magnetic attraction at the bottom of the steel plate causes multiple magnetic blocks 4010 to move upward. The upward movement of the multiple magnetic blocks 4010 drives the joint-stop frame 4041 to slide upward along the outer wall of the slag collection frame 404 via the connecting strip 409. This causes the top of the joint-stop frame 4041 to fit against the bottom of the steel plate, and the outer walls of the two rolling rods 408 to abut against the bottom of the steel plate. Therefore, under the fitting action of the top of the joint-stop frame 4041 against the bottom of the steel plate, there will be no gap between the top of the slag collection frame 404 and the bottom of the steel plate, allowing the slag to be better collected inside the slag collection frame 404.

[0049] During the movement of the slag collection frame 404, the two torsion bars 405 and the torsion limiting slide bar 407 move together. Since the torsion limiting slide bar 407 always slides along the inner wall of the path groove 402, it will not twist. In other words, the torsion bars 405 will not twist either. Therefore, the sealing flap 406, which is fixedly connected to the outer wall of the torsion bar 405, will not rotate downwards. As a result, the slag inside the slag collection frame 404 will not spill from the bottom of the slag collection frame 404. When the torsion limiting slide bar 407 slides into the inside of the fan-shaped groove 403 along the path groove 402, the slag collection frame 404 moves to a position where it can hold slag. At the same time, the gravity of the sealing flap 406 causes the torsion rod 405 and the torsion limiting slide 407 to rotate downwards until the bottom of the torsion limiting slide 407 contacts the bottom wall of the fan-shaped groove 403. The sealing flap 406 rotates downwards, causing the bottom of the slag collection frame 404 to be opened. The slag inside the slag collection frame 404 falls into the scooping trough 4015 through the bottom opening, thus automatically cleaning the inside of the slag collection frame 404. Since the slag collection frame 404 pours the slag into the scooping trough 4015, it does not cause pollution inside the device.
