Description

Technical Field

[0001] The invention relates to the technical field of flange transportation, in particular to a flange transportation mechanism. Background Art

[0002] On a large-scale flange automated production line, flanges need to be transported from one workstation to another. If high-precision processing or assembly of the flange is required, a conveying mechanism is usually required to accurately transport the flange from the conveyor or the equipment of the previous processing step and place it on the fixture of the welding station or other processing station.

[0003] When traditional transport mechanisms transport flanges to processing or welding stations, a robotic arm typically uses a clamp to clamp the flange from the conveyor to a fixture at another station. However, since the size of the clamped flange and the distance between the jaws remain constant, if the size of the clamped flange does not match the fixed clamping range of the clamp, the clamping will be loose and incomplete. Furthermore, when processing flanges of different sizes, the clamps of different specifications need to be frequently replaced, resulting in low production efficiency.

[0004] When a flange is transported from one workstation to another by means of a conveying mechanism, the conveyor and the flange transport mechanism must first be docked to ensure that the flange moves smoothly to the designated clamping position on the equipment. However, since the heights of different conveyors and the flange transport mechanism are different, when the height difference between the two is greater than the adjustable range of the conveyor height, it is difficult to ensure that the flange moves accurately to the clamping position of the equipment, which in turn affects the clamping accuracy of the clamping claws, resulting in low transportation efficiency and poor flexibility.

[0005] During the process of the flange being transported by the conveyor to the clamping position of the equipment, the flange is easily offset when moving on the conveyor, making it difficult to accurately move to the clamping position of the equipment. In addition, during the clamping process, in order to accurately transport the flange to the fixture of the processing station, the clamping jaws need to repeatedly rise and fall significantly during the clamping process, resulting in low operating efficiency.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figure 3 、 Figure 5-Figure 7As shown, a flange transportation mechanism of the present invention includes an operating table 1, a docking structure 2 installed at the end of the operating table 1, a lifting structure 6 provided on the operating table 1, a flip structure 7 matched with the lifting structure 6, and an adjustment structure 8 connected to the flip structure 7; two driving blocks 803 are slidably connected to the rotating seat 801, and the driving blocks 803 are threadedly connected to the fourth screw rod 802. The first rack 804 is fixedly connected to the outer side of the two driving blocks 803, and the first rack 804 is internally slidably connected to the positioning block 805. The setting of the positioning block 805 avoids the second rack 807 The first rack 804 falls off, and a positioning bar 806 is fixedly connected to the outer side of the positioning block 805. The first rack 804 is meshed with a second rack 807. The positioning bar 806 is slidably connected to the inner wall of the second rack 807. A spring 808 is fixedly connected between the end of the positioning bar 806 and the inner wall of the second rack 807. Under the reset action of the spring 808, the second rack 807 is driven to press against the first rack 804. The end of the fourth screw rod 802 is fixedly connected to a knob 809. The two ends of the fourth screw rod 802 are respectively provided with threads with opposite rotation directions. The output shaft of the fifth motor 704 is fixedly connected to the There is a rotating seat 801. When the bracket 304 lifts the flange, it needs to be clamped by the clamping claws and transported to the processing station. Before clamping, it is necessary to adjust the distance between the jaws according to the size of the transported flange, and by pulling the two second racks 807 outward at the same time, the second rack 807 is no longer engaged with the first rack 804, and then the two second racks 807 are pulled in both directions. The second rack 807 drives the positioning block 805 to slide inside the first rack 804. When the distance between the two second racks 807 is adjusted to the appropriate size, the two second racks 807 are released, and the two are engaged with each other. At this time, the two second racks 807 are preliminarily adjusted. The spacing between the rack 807 and the clamping rod 902 is adjusted, and then the knob 809 is turned, and the knob 809 drives the fourth screw rod 802 to rotate on the rotating seat 801. Since the two ends of the fourth screw rod 802 are provided with threads with opposite rotation directions, the two driving blocks 803 will be driven to slide in opposite directions during the rotation of the knob 809, and the driving blocks 803 will drive the two first racks 804 and the second rack 807 to move in the directions of both sides respectively. At this time, the spacing between the clamping rods 902 on both sides is accurately adjusted to ensure that the size of the flange matches the fixed clamping range of the clamping jaws, thereby improving the firmness of the clamping and facilitating adaptation to flanges of different sizes, with strong practicality.

[0036] Specifically, such as Figure 1 、 Figure 3 and Figure 4As shown, the operating table 1 is fixedly connected to two mounting seats 501, a first mounting plate 503 is slidably connected between the two second guide rods 502, a second screw rod 504 is rotatably connected between the two mounting seats 501, a second motor 505 is fixedly connected to one of the mounting seats 501, an output shaft of the second motor 505 is fixedly connected to the second screw rod 504, the first mounting plate 503 and the second screw rod 504 are threadedly connected, a drag chain 506 is installed on the top of the first mounting plate 503, and the setting of the drag chain 506 on the top of the first mounting plate 503 effectively protects the power cord. A first guide rail 507 is fixedly connected. Since the slide 508 at the bottom of the slide 601 is slidably connected to the first guide rail 507, the stability of the slide 601 during translation is enhanced. The slide 508 is slidably connected to the first guide rail 507 to move the flange to the vicinity of the work station. The second motor 505 on the mounting seat 501 drives the second screw rod 504 to rotate, and then the second screw rod 504 drives the first mounting plate 503 to slide along the two second guide rods 502 toward the work station. The first mounting plate 503 drives the slide 601 to move toward the work station. At this time, the slide 601 can drive the clamping claw and the flange to move to the vicinity of the work station, and the transportation efficiency is very high.

[0037] Specifically, such as Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, a slide 601 is fixedly connected between the slide 508 and the first mounting plate 503, and a protective plate 607 is fixedly connected to the outer side of the slide 601. The protective plate 607 on the outer side of the slide 601 is removed to facilitate maintenance of the parts inside the slide 601, which has strong flexibility. The inner rotation of the slide 601 is connected to a third screw rod 603, and the top of the slide 601 is fixedly connected to a third motor 604. The output shaft of the third motor 604 is fixedly connected to the top of the third screw rod 603. The third screw rod 603 is threadedly connected to the second mounting plate 605. The second mounting plate Four sliders 606 are fixedly connected to the back of 605, and the sliders 606 are slidably connected to the second guide rails 602. The protective plate 607 passes through the second mounting plate 605. When the four clamping rods 902 clamp the flange, the third motor 604 located at the top of the slide 601 drives the third screw rod 603 to rotate, and the third screw rod 603 drives the second mounting plate 605 to move upward. The second mounting plate 605 slides upward along the two second guide rails 602 through the four sliders 606 on the back side, so that the second mounting plate 605 drives the clamping jaws and the flange to rise to the predetermined position, which is convenient for the subsequent transportation of the flange to the fixture of the processing station.

[0038] Specifically, such as Figure 3 and Figure 5As shown, a connecting frame 701 is fixedly connected to a side close to the outer side of the second mounting plate 605, and a rotating frame 703 is fixedly connected to the output shaft of the fourth motor 702. When the clamp drives the flange to move near the work station, the flange needs to be flipped to a suitable angle and aligned with the fixture of the processing station. First, the fourth motor 702 installed on the connecting frame 701 drives the rotating frame 703 to rotate 90 degrees counterclockwise, so that the clamp and the flange are rotated to directly above the fixture of the processing station. The rotating frame 703 is fixedly connected to the fifth motor 704, and the fifth motor 704 drives the rotating seat 801 to rotate a certain angle until the four clamping rods 902 drive the flange to flip to the specified angle. Then the third motor 604 drives the clamp and the flange to descend until the flange is placed on the fixture of the processing station. At this time, the flange is accurately transported from the conveyor to the processing station, and the transportation efficiency is high.

[0039] Specifically, such as Figure 3 、 Figure 5 and Figure 6 As shown, the two second racks 807 are rotatably connected to a rotating bar 901, and a latch 903 is engaged on the rotating bar 901. The rotating bar 901 is provided with a driving bar 904, and a plurality of sockets 905 are provided on the driving bar 904. The latch 903 runs through one of the sockets 905. When adjusting the spacing of the jaws, the latch 903 is engaged with different sockets 905, thereby avoiding the problem that the constant length of the driving bar 904 affects the adjustment of the jaw spacing. The flexibility is strong, the driving bar 904 is rotatably connected to the latch 903, and a connecting bar 906 is provided between the two driving bars 904. The ends of the driving bars 904 are rotatably connected to the connecting bars 906. A hydraulic cylinder 907 is fixedly connected to the rotating seat 801. The telescopic end of the hydraulic cylinder 907 is fixedly connected to the connecting bar 906. At this time, the clamping claw moves to the top of the flange bracket 304, and the two pairs of clamping rods 902 are located on both sides of the flange. Then the telescopic end of the hydraulic cylinder 907 contracts inward, while driving the connecting bar 906 to move toward the direction of the hydraulic cylinder 907, and gradually reducing the angle between the two driving bars 904, thereby driving the two rotating bars 901 to rotate toward the middle position, driving the clamping rods 902 on both sides to clamp the flange. At this time, the clamping of the flange is completed, and it is very firm.

[0040] Specifically, such as Figure 2 、 Figure 8 and Figure 9As shown, one side of the operating table 1 is fixedly connected to two mounting brackets 201, a support bracket 203 is slidably connected between the two first guide rods 202, a first screw rod 204 is rotatably connected between the two mounting brackets 201, the support bracket 203 and the first screw rod 204 are threadedly connected, a handle 205 is fixedly connected to the bottom end of the first screw rod 204, six rotating shafts 206 are rotatably connected to the support bracket 203, three rotating shafts 206 near the outside are fixedly connected to the first rollers 207, and three rotating shafts 206 near the inside are fixedly connected to two second rotating rollers. Roller 208, a first motor 209 is fixedly connected to the support frame 203, and the output shaft of the first motor 209 is fixedly connected to the adjacent rotating shaft 206. In the process of transporting the flange from the conveyor to other processing stations, it is necessary to first adjust the height of the support frame 203 on the operating table 1 according to the height of the conveyor, so as to ensure that the flange is smoothly transported to the support frame 203. It is only necessary to rotate the handle 205 at the bottom end of the mounting frame 201. At this time, the handle 205 drives the first screw rod 204 to rotate between the two mounting frames 201. Since the support frame 203 and the first screw rod 204 are threadedly connected, the first The screw rod 204 can drive the support frame 203 to slide up and down along the two first guide rods 202 until the height of the support frame 203 is adjusted to the same height as the conveyor, and then the power of the first motor 209 is turned on. At this time, the first motor 209 drives the rotating shaft 206 connected to its output shaft to rotate, and then the rotating shaft 206 drives the two second rollers 208 to rotate, and the rotating shaft 206 drives the pulley 210 at the other end to rotate. The rotating shafts 206 at both ends are fixedly connected to a pulley 210, and the two rotating shafts 206 in the middle are fixedly connected to two pulleys 210 A belt 211 is wound between the two adjacent pulleys 210. Since the rotating shafts 206 at both ends of the support frame 203 are respectively installed with pulleys 210 and belts 211 between the two middle rotating shafts 206, and the two middle rotating shafts 206 are also installed with pulleys 210 and belts 211, the first motor 209 can simultaneously drive the corresponding first roller 207 and second roller 208 to rotate. At this time, the flange moved to the support frame 203 can be moved by the first roller 207 and the second roller 208 until the flange moves to the specified clamping position, thereby improving the transportation efficiency of the flange.

[0041] Specifically, such as Figure 2 and Figure 8-Figure 9As shown, the first screw rod 204 is threadedly connected to a slide plate 301, and the mounting frame 201 at the bottom is fixedly connected to a guide bar 303. The setting of the guide bar 303 prevents the slide plate 301 from rotating with the first screw rod 204, thereby ensuring that the hydraulic rod 302 moves up and down with the support frame 203, ensuring that the top surface of the bracket 304 and the highest point of the second roller 208 are flush with each other in the initial state, ensuring that the flange can be smoothly moved to the bracket 304, and the operation is simple. The slide plate 301 is slidably connected to the guide bar 303, and the hydraulic rod 302 The telescopic end is fixedly connected to a bracket 304, and two positioning rods 305 are fixedly connected to the bracket 304. When the flange moves to the top of the bracket 304, the flange will first conflict with the two positioning rods 305 on the bracket 304. At this time, the flange will no longer move, and then the telescopic end of the hydraulic rod 302 drives the bracket 304 to lift the flange upward, which is beneficial to reduce the distance between the flange and the clamping jaws, avoids the clamping jaws from moving up and down significantly, and improves transportation efficiency. At the same time, the slide plate 301 at the bottom of the hydraulic rod 302 is threadedly connected to the first screw rod 204.

[0042] Specifically, such as Figure 2 As shown, four slide bars 401 are slidably connected to the support frame 203, and a tension spring 403 is fixedly connected between the guide plate 402 and the outer wall of the support frame 203. The two slide bars 401 near the outer side are threadedly connected with nuts 404, and the nuts 404 are arranged on the outer side of the support frame 203. Therefore, when the flange is offset or there is an error in size during movement, the two guide plates 402 can move in the outer direction respectively to ensure that the flange moves smoothly on the support frame 203 with strong flexibility. The nuts 404 and the outer wall of the support frame 203 conflict with each other. In the process of the flange being moved from the conveyor to the first rotating roller 207, since the two ends of the support frame 203 are equipped with guide plates 402 through the slide bars 401, and the ends of the two guide plates 402 close to the conveyor form a "V" shape structure, the movement of the flange is controlled. The movement plays a guiding role, ensuring that the flange moves between the two guide plates 402, avoiding the problem of the flange slipping off the conveyor and falling to the ground, and the setting of the guide plates 402 ensures that the flange moves smoothly to the clamping position of the equipment, ensuring the accuracy of the clamping claws. When flanges of different sizes need to be transported to the processing station, it is necessary to first adjust the spacing between the two guide plates 402. Just pull the slide bar 401 in the outward direction respectively. When the spacing between the two guide plates 402 is adjusted to the appropriate size, rotate the nuts 404 on the slide bars 401 on both sides respectively until the nuts 404 and the outer wall of the support frame 203, and under the resetting action of the tension spring 403, the nuts 404 are driven to press against the outer wall of the support frame 203. At this time, the spacing between the two guide plates 402 is effectively adjusted, which is convenient for adapting to flanges of different sizes.

[0043] When the present invention is in use, in the process of transporting the flange from the conveyor to other processing stations, it is necessary to first adjust the height of the support frame 203 on the operating table 1 according to the height of the conveyor, so as to ensure that the flange is smoothly transported to the support frame 203, and it is only necessary to rotate the handle 205 at the bottom end of the mounting frame 201. At this time, the handle 205 drives the first screw rod 204 to rotate between the two mounting frames 201. Since the support frame 203 and the first screw rod 204 are threadedly connected, the first screw rod 204 can drive the support frame 203 to slide up and down along the two first guide rods 202 until the height of the support frame 203 is adjusted to the same height as the conveyor, and then turn on the power of the first motor 209. At this time, the first motor 209 is turned on. The motor 209 drives the rotating shaft 206 connected to its output shaft to rotate, and then the rotating shaft 206 drives the two second rollers 208 to rotate, and the rotating shaft 206 drives the pulley 210 at the other end to rotate. Since the rotating shafts 206 at both ends of the support frame 203 are respectively installed with pulleys 210 and belts 211 between the two middle rotating shafts 206, and the pulley 210 and belt 211 are also installed between the two middle rotating shafts 206, the first motor 209 can simultaneously drive the corresponding first roller 207 and the second roller 208 to rotate. At this time, the flange moved to the support frame 203 can be moved by the first roller 207 and the second roller 208 until the flange moves to the specified clamping position, thereby providing a fixed position for the flange. The transportation efficiency of the flange is improved. At the same time, in the process of the flange being moved from the conveyor to the first roller 207, since guide plates 402 are installed at both ends of the support frame 203 through the sliding rod 401, and the ends of the two guide plates 402 close to the conveyor form a "V"-shaped structure, the movement of the flange is guided, ensuring that the flange moves between the two guide plates 402, avoiding the problem of the flange slipping off the conveyor and falling to the ground, and the setting of the guide plates 402 ensures that the flange moves smoothly to the clamping position of the equipment, ensuring the accuracy of the clamping claws. When flanges of different sizes need to be transported to the processing station, the distance between the two guide plates 402 needs to be adjusted first. It is only necessary to pull the slide bar 401 in the outward direction respectively. When the distance between the two guide plates 402 is adjusted to a suitable size, the nuts 404 on the slide bars 401 on both sides are rotated respectively until the nuts 404 are against the outer wall of the support frame 203, and the nuts 404 are driven to press against the outer wall of the support frame 203 under the resetting action of the tension spring 403. At this time, the distance between the two guide plates 402 is effectively adjusted to adapt to flanges of different sizes. At the same time, the nuts 404 are arranged on the outside of the support frame 203. When the flange deviates during movement or there is a size error, the two guide plates 402 can be moved in the outward direction respectively to ensure that the flange moves smoothly on the support frame 203, with strong flexibility.

[0044] When the flange moves to the top of the bracket 304, the flange will first conflict with the two positioning rods 305 on the bracket 304. At this time, the flange will no longer move, and then the telescopic end of the hydraulic rod 302 drives the bracket 304 to push the flange upward, which is conducive to reducing the distance between the flange and the clamping jaws, avoiding the clamping jaws from moving up and down significantly, and improving transportation efficiency. At the same time, due to the threaded connection between the slide plate 301 at the bottom of the hydraulic rod 302 and the first screw rod 204, and the setting of the guide bar 303 prevents the slide plate 301 from rotating with the first screw rod 204, thereby ensuring that the hydraulic rod 302 moves up and down with the support frame 203, ensuring that the top surface of the bracket 304 and the highest point of the second roller 208 are flush with each other in the initial state, ensuring that the flange can be smoothly moved to the bracket 304, and easy to operate;

[0045] After the bracket 304 lifts up the flange, it needs to be clamped by the clamping jaws and transported to the processing station. Before clamping, the distance between the jaws needs to be adjusted according to the size of the transported flange. By pulling the two second racks 807 outward at the same time, the second racks 807 are no longer engaged with the first rack 804. Then, the two second racks 807 are pulled in both directions. The second rack 807 drives the positioning block 805 to slide inside the first rack 804 through the positioning bar 806. The setting of the positioning block 805 prevents the second rack 807 from sliding from the first rack 804. The first rack 804 is pressed against the second rack 807 by the spring 808, and the second rack 807 is pressed against the first rack 804. The second rack 807 and the first rack 804 are engaged with each other. The spacing between the second rack 807 and the clamping rod 902 is preliminarily adjusted. Then, the knob 809 is turned to drive the fourth screw rod 802 to rotate on the rotating seat 801. Since the two ends of the fourth screw rod 802 are provided with threads with opposite rotation directions, the knob 809 is turned. During the process, the two driving blocks 803 will be driven to slide in opposite directions, and the driving blocks 803 will drive the two first racks 804 and the second racks 807 to move in the directions of both sides respectively. At this time, the distance between the clamping rods 902 on both sides is accurately adjusted to ensure that the size of the flange matches the fixed clamping range of the clamping jaws, thereby improving the firmness of the clamping and facilitating the adaptation to flanges of different sizes. It is highly practical. At this time, the clamping jaws move to the top of the bracket 304, and the two pairs of clamping rods 902 are located on both sides of the flange. Then the telescopic end of the hydraulic cylinder 907 contracts inwards, and at the same time When the connecting bar 906 is moved toward the direction of the hydraulic cylinder 907, the angle between the two driving bars 904 is gradually reduced, thereby driving the two rotating bars 901 to rotate toward the middle position, driving the clamping rods 902 on both sides to clamp the flange. At this time, the flange is clamped, and the firmness is strong. At the same time, since a plurality of sockets 905 are provided on the driving bar 904, when adjusting the spacing of the jaws, the latch 903 is engaged with different sockets 905, thereby avoiding the problem that the constant length of the driving bar 904 affects the adjustment of the jaw spacing, and the flexibility is strong.

[0046] After the four clamping rods 902 clamp the flange, the third motor 604 located at the top of the slide 601 drives the third screw 603 to rotate, and the third screw 603 drives the second mounting plate 605 to move upward, and the second mounting plate 605 slides upward along the two second guide rails 602 through the four sliders 606 on the back side, so that the second mounting plate 605 drives the clamping claws and the flange to rise to the predetermined position, which is convenient for the subsequent transportation of the flange to the fixture of the processing station, and at the same time, the protective plate 607 on the outside of the slide 601 is removed to facilitate the maintenance of the parts inside the slide 601, which has strong flexibility. Then the flange needs to be moved to the work station. The second motor 505 on the mounting base 501 drives the second screw rod 504 to rotate, and then the second screw rod 504 drives the first mounting plate 503 to slide along the two second guide rods 502 toward the working position, and the first mounting plate 503 drives the slide 601 to move toward the working position. Due to the sliding connection between the slide 508 at the bottom of the slide 601 and the first guide rail 507, the stability of the slide 601 during translation is enhanced. At this time, the slide 601 can drive the clamping claw and the flange to move near the working position, and the transportation efficiency is very high. The setting of the drag chain 506 at the top of the first mounting plate 503 effectively protects the power cord.

[0047] When the clamp drives the flange to move near the workstation, the flange needs to be flipped to a suitable angle and aligned with the fixture of the processing station. First, the fourth motor 702 installed on the connecting frame 701 drives the rotating frame 703 to rotate 90 degrees counterclockwise, so that the clamp and flange are rotated to directly above the fixture of the processing station. Then, the fifth motor 704 installed on the rotating frame 703 drives the rotating seat 801 to rotate a certain angle until the four clamping rods 902 drive the flange to flip to the specified angle. Then the third motor 604 drives the clamp and flange to descend until the flange is placed on the fixture of the processing station. At this time, the flange is accurately transported from the conveyor to the processing station, and the transportation efficiency is high.
