Description

Technical Field

[0001] This invention relates to the field of weld grinding technology, and in particular to a grinding platform suitable for weld seams of multi-section welded blades. Background Technology

[0002] Multi-joint welded blades are widely used in high-end equipment fields such as aerospace, energy and power, and engineering machinery. The quality of their welds directly determines the structural strength, aerodynamic performance and service life of the blades. Therefore, weld grinding is a key process in blade manufacturing.

[0003] Currently, existing equipment and processes for grinding the weld seams of multi-section welded blades have several shortcomings. First, loading, unloading, and flipping operations are generally done manually. Operators must move the workpieces to the grinding station, grind one side, and then manually flip the workpiece to grind the other side, resulting in high labor intensity and low efficiency. Second, existing grinding robots mostly use manual programming or teaching methods to plan the grinding trajectory. For multi-section welded blades of different specifications and contours, reprogramming or teaching is required, leading to poor adaptability, long debugging cycles, and an inability to quickly respond to diverse production needs. Furthermore, manual programming is prone to trajectory deviations, resulting in incomplete or excessive grinding of the weld seams, affecting blade quality. Third, metal debris generated during grinding easily adheres to the workpiece surface and the grinding station. If not cleaned promptly, it will affect subsequent processing and the surface quality of the workpiece.

[0004] Therefore, a grinding platform suitable for the weld seams of multi-section welded blades is provided to address the above-mentioned problems. Summary of the Invention

[0018] The positive and progressive effects of this invention are as follows:

[0019] The aforementioned grinding platform is suitable for the weld seams of multi-section welded blades.

[0020] By integrating a loading platform, a handling robot, a flipping mechanism, a grinding robot, and clamping fixtures, an automated process is constructed, encompassing workpiece loading, contour scanning, trajectory generation, two-sided grinding, and unloading. The handling robot, equipped with a scanner, automatically scans the contour of the workpiece to be ground, automatically generating a suitable grinding trajectory without manual programming or teaching, significantly shortening the equipment debugging cycle. It adapts to the grinding needs of multi-section welding blades of different specifications, improving the equipment's versatility.

[0021] The system is equipped with an air blowing shell and a matching air supply mechanism. After grinding, it can blow away debris adhering to the workpiece surface to ensure the cleanliness of the workpiece surface and prevent residual debris from affecting the quality of subsequent processing or assembly. A lifting mechanism is also included to allow the air blowing shell to move up and down, bringing it closer to the workpiece during cleaning to improve the cleaning effect, and keeping it away from the workpiece during grinding to avoid interfering with the grinding robot's movements.

[0039] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0040] like Figures 1-14 As shown, a grinding platform suitable for the weld seam of multi-section welded blades includes a grinding chamber 2; a transport robot 3 and a material turning mechanism 5 are provided on one side of the grinding chamber 2; a clamping part 4 and a scanner 7 are provided at the end of the transport robot 3.

[0041] The grinding chamber 2 is equipped with a grinding robot 10 and a clamping fixture 11, with the clamping fixture 11 located on the side of the grinding robot 10 close to the transport robot 3.

[0042] A chip conveyor 8 is provided below the clamping fixture 11.

[0043] An air blowing shell 12 is provided above the clamping fixture 11, and the air blowing shell 12 is connected to a lifting part; the air blowing shell 12 is also connected to an air supply mechanism 17.

[0044] It also includes a drive mechanism 14, which is connected to a switching mechanism 18, which allows the drive mechanism 14 to be switched between the air supply mechanism 17 and the chip conveyor 8.

[0045] The material handling robot 3 is provided with a material loading platform 6 on the side away from the grinding chamber 2. The material loading platform 6 can be a roller conveyor.

[0046] The polishing chamber 2 has an opening 201 on the side near the transport robot 3. A lifting door is provided at the opening 201, which can be closed during polishing to prevent polishing debris from flying out of the polishing chamber 2.

[0047] A monitoring camera is installed in the grinding chamber 2 to facilitate monitoring and filming the grinding process of the workpiece.

[0048] It also includes a base plate 1, and the grinding chamber 2, chip conveyor 8, drive mechanism 14, handling robot 3, material turning mechanism 5, grinding robot 10 and material loading platform 6 are all installed on the base plate 1.

[0049] When grinding the weld seam of the multi-section welded blades, the workpiece to be ground is placed on a pallet, which is placed above one side of the loading platform 6, and an empty pallet is placed on the other side of the loading platform 6.

[0050] The transport robot 3 scans the workpiece to be polished on the pallet using its scanner 7, performing a contour scan and automatically generating a polishing trajectory with the help of the control system. Then, it clamps the workpiece using the clamping part 4. Next, the transport robot 3 feeds the workpiece into the polishing chamber 2 through the opening 201 and places it in the clamping fixture 11. The workpiece is clamped and fixed by the clamping fixture 11. The weld seam on the side of the workpiece facing the polishing robot 10 is polished by the polishing robot 10. After this side is polished, the transport robot 3 transports the workpiece to the flipping mechanism 5, which flips the workpiece 180° to make its two sides interchange. Then, the transport robot 3 transports the workpiece back to the clamping fixture 11 and clamps and fixes it. At this time, the other side of the workpiece faces the polishing robot 10, and the polishing robot 10 polishes this side. While this side is being polished, the transport robot 3 moves its scanner 7 to an empty pallet to scan and determine the product placement position. Finally, the transport robot 3 transports the workpiece, which has been polished on both sides, to an empty pallet for placement.

[0051] By repeating the above operations, all workpieces on the pallet are ground, and the empty pallet is filled with ground workpieces. Then, the pallet carrying the ground workpieces is moved to the outside of the loading platform 6 for stacking using a palletizing device. Simultaneously, the pallet on the loading platform 6 (the pallet that originally held the workpieces to be ground) is moved to one side of the loading platform 6 (the original location of the empty pallet). Then, the next pallet carrying the workpieces to be ground is placed on one side of the loading platform 6 (this can be done manually or using the palletizing device). It should be noted that multiple pallets carrying workpieces to be ground are stacked outside the loading platform 6 to facilitate the placement of these pallets by the palletizing device and manual labor. The stacked pallets can also be transported using a forklift.

[0052] like Figure 3 As shown, the clamping part 4 includes a carrier plate 401; the carrier plate 401 is connected to the end of the handling robot 3, and two sets of slide rails 402 are symmetrically arranged on both sides of the carrier plate 401. A slider 403 is slidably installed on the slide rail 402, and a clamping bar 404 is fixed on the slider 403. A first cylinder 405 is fixed on both sides of the carrier plate 401, and the output shaft of the first cylinder 405 is connected to the slider 403.

[0053] The first cylinder 405 drives the slider 403 and the clamping bar 404 to move together, so that the two clamping bars 404 move closer or further apart. When they move closer, the two clamping bars 404 clamp the workpiece; when they move further apart, the two clamping bars 404 release the workpiece.

[0054] like Figure 3 As shown, the scanner 7 is installed in the middle of the carrier plate 401. When the clamping part 4 does not clamp the workpiece, the scanner 7 is not blocked by the workpiece and can perform scanning.

[0055] like Figure 4 As shown, the material turning mechanism 5 includes a support base 501. A side frame 502 is fixed on both sides of the top of the support base 501. A turning frame 503 is rotatably installed between the two side frames 502. A first motor 506 is fixedly installed on one side of the side frame 502. The output shaft of the first motor 506 is connected to the turning frame 503. A second cylinder 504 is fixed on both sides of the turning frame 503. A pressure block 505 is fixed on the output shaft of the second cylinder 504.

[0056] When the workpiece is flipped by the flipping mechanism 5, the workpiece is placed in the flipping frame 503. The second cylinder 504 drives the pressure block 505 to press the workpiece, thereby clamping the workpiece. Then, the first motor 506 drives the flipping frame 503 and the clamped workpiece to flip together by 180°, thereby swapping the upper and lower sides.

[0057] like Figures 5-8As shown, the chip conveyor 8 includes a cylinder 801; one end of the cylinder 801 is fixedly connected to a chip hopper 803, and the other end of the cylinder 801 extends to the outside of the grinding chamber 2; a rotating cylindrical tube 804 is rotatably installed inside the cylinder 801 and the chip hopper 803, and a spiral blade 805 is fixedly installed on the rotating cylindrical tube 804; a chip discharge port 802 is provided at the end of the cylinder 801 extending to the outside of the grinding chamber 2; a clamping fixture 11 is installed at the top of the chip hopper 803; and an air supply mechanism 17 is installed on one side of the chip hopper 803.

[0058] The clamping fixture 11 includes a support frame 1102 fixed to both sides of the top of the chip hopper 803. The support frame 1102 is equipped with a pneumatic gripper 1101, which can be a finger cylinder.

[0059] The workpiece is placed in the clamping fixture 11 and clamped and fixed by the pneumatic gripper 1101. The grinding debris is collected by the chip hopper 803. When the drive mechanism 14 is connected to the rotating tube 804 through the switching mechanism 18, the drive mechanism 14 drives the rotating tube 804 to rotate, and the chip is conveyed by the spiral blades 805 and discharged from the chip discharge port 802.

[0060] A container can be placed below the chip discharge port 802 to collect the material. Once full, the material can be manually poured out.

[0061] like Figure 7 , Figures 12-14 As shown, a side shell 13 is fixed to one side of the chip hopper 803; the air supply mechanism 17 includes a rotating cylinder 1704 disposed inside the side shell 13, the rotating cylinder 1704 is rotatably connected to one side of the chip hopper 803, a cam 1705 is fixedly sleeved on the rotating cylinder 1704, and multiple air injection parts are installed on the outside of the side shell 13; the air outlet of the air injection part is connected to an air pipe 1702, the air pipe 1702 is fixed to the inner wall of the grinding chamber 2, and one end of the air pipe 1702 is connected to a corrugated hose 1701, the bottom end of the corrugated hose 1701 is connected to a port disposed at the top of the air blowing strip shell 12; a switching mechanism 18 is installed between the rotating round pipe 804 and the rotating cylinder 1704.

[0062] like Figure 14As shown, the air injection unit includes an air cylinder 1703 fixed to the side shell 13. A guide plate 1707 is fixed inside the air cylinder 1703. A piston 1708 is installed inside the air cylinder 1703. A pressure column 1706 is fixed to the piston 1708. The pressure column 1706 is connected to a guide hole provided on the guide plate 1707. One end of the pressure column 1706 abuts against a cam 1705. A first spring 1709 is provided inside the air cylinder 1703. Both ends of the first spring 1709 abut against the piston 1708 and the inner end face of the air cylinder 1703, respectively. A first one-way valve 1710 and a second one-way valve 1711 are installed on the air cylinder 1703. The first one-way valve 1710 is connected to the air pipe 1702.

[0063] The first one-way valve 1710 is used for air outlet, and the second one-way valve 1711 is used for air inlet. In specific implementation, the second one-way valve 1711 is connected to the outside of the grinding chamber 2 through a pipeline to prevent air from entering the grinding chamber 2, thereby preventing the entry of debris. Furthermore, a filter can be installed on the pipeline to filter the incoming air.

[0064] When the drive mechanism 14 is connected to the rotating drum 1704 via the switching mechanism 18, the drive mechanism 14 drives the rotating drum 1704 and the cam 1705 to rotate together. The protruding part of the cam 1705 pushes the pressure column 1706, which in turn drives the piston 1708 to push the gas in the air cylinder 1703 out through the first one-way valve 1710 and compress the third spring 1809. The gas is then delivered through the air pipe 1702 and the corrugated hose 1701, and blown out from below the air blowing strip shell 12. This allows for air cleaning of the sides of the polished workpiece, removing attached debris. When the protruding part of the cam 1705 leaves the pressure column 1706, the compression force of the third spring 1809 resets the piston 1708 and the pressure column 1706. The air cylinder 1703 then draws in outside air through the second one-way valve 1711 to replenish the air supply. Figure 14 As shown, two symmetrical air injection sections are provided. When the protruding part of the cam 1705 squeezes the pressure column 1706 of one air injection section, the pressure column 1706 of the other air injection section is not squeezed by the protruding part. During the rotation of the cam 1705, the two air injection sections alternately inject air into the air tube 1702 and alternately draw in outside air to replenish it.

[0065] The end of the pressure column 1706 may be spherical or fitted with balls to reduce rolling friction with the cam 1705. The pressure column 1706 is preferably a non-circular rod type.

[0066] like Figures 8-13As shown, the switching mechanism 18 includes two sets of plug-in components and a circular shaft 1801 that is clearance-fitted with the rotating circular tube 804 (multiple balls can be provided on the cylindrical surface of the circular shaft 1801, and the two roll friction when the circular shaft 1801 and the rotating circular tube 804 rotate relative to each other). The two sets of plug-in components are symmetrically installed at both ends of the circular shaft 1801, and the two plug-in components are respectively located at one end of the rotating circular tube 804 and one end of the rotating cylinder 1704. An end plate 1802 is fixed at one end of the rotating circular tube 804 and one end of the rotating cylinder 1704, and multiple arc-shaped grooves 18021 distributed in a ring array are opened on the end plate 1802. The plug-in component located at one end of the rotating circular tube 804 is connected to a telescopic shaft, and the telescopic shaft is connected to the output end of the drive mechanism 14. The plug-in component located at one end of the rotating cylinder 1704 is connected to a pushing part.

[0067] like Figure 11 As shown, the plug-in assembly includes a connecting disk 1803 fixed to the end face of the round shaft 1801; a plurality of outer cylinders 1804 arranged in a ring array are fixed on the connecting disk 1803, and the outer cylinders 1804 are slidably fitted with inserts 1808, and the inserts 1808 are used to insert into the arc-shaped groove 18021. A third spring 1809 is provided inside the outer cylinders 1804, and the two ends of the third spring 1809 abut against one end of the insert 1808 and the inner end face of the outer cylinder 1804, respectively.

[0068] like Figure 9 As shown, the telescopic shaft includes a rotating sleeve 1806 with a square hole in the middle. A square post 1807 is slidably fitted into the square hole. One end of the square post 1807 is fixed to the middle of a connecting plate 1803 of an insertion assembly located at one end of the rotating circular tube 804. A second spring 1805 is provided on one side of the rotating sleeve 1806. The rotating sleeve 1806 is connected to the drive mechanism 14. One end of the second spring 1805 abuts against the end face of the rotating sleeve 1806, and the other end abuts against the connecting plate 1803 of an insertion assembly located at one end of the rotating circular tube 804.

[0069] The pushing part is disposed inside the side shell 13; the pushing part includes a connecting shaft 1816 and a movable seat 1812; one end of the connecting shaft 1816 is fixed to the connecting plate 1803 of the plug-in assembly located at one end of the rotating cylinder 1704, the movable seat 1812 is rotatably connected to the connecting shaft 1816, a plurality of fixed posts 1810 are fixed inside the side shell 13, the end of the fixed post 1810 is fixed with a guide post 1811, the guide post 1811 is engaged with the hole opened on the movable seat 1812, the fixed post 1810 and the movable seat 1812 are elastically connected by a fourth spring 1813, and the fourth spring 1813 is sleeved on the guide post 1811, a first wedge block 1814 is fixed on one side of the movable seat 1812, the first wedge block 1814 abuts against a second wedge block 1815, and the top of the second wedge block 1815 is connected to the lifting part.

[0070] like Figures 8-13 As shown, at this time, the insertion component at one end of the circular shaft 1801 is inserted into the arc groove 18021 at the upper end plate 1802 of the rotating circular tube 804, and the other insertion component is separated from the arc groove 18021 at the upper end plate 1802 of the rotating drum 1704. The drive mechanism 14 is connected to the rotating circular tube 804 through the switching mechanism 18. When the drive mechanism 14 drives the switching mechanism 18 to rotate, the switching mechanism 18 pushes the wall of the arc groove 18021 at the upper end plate 1802 of the rotating circular tube 804 through the insertion post 1808, so that the rotating circular tube 804 rotates and the chip conveyor 8 is driven. The insertion component is separated from the end plate 1802 on the rotating drum 1704 and is not connected, so the rotating drum 1704 is not driven and the air blowing strip shell 12 does not blow air. Furthermore, as described above, the lifting unit positions the second wedge block 1815 and the air blowing shell 12 at a high position, with the air blowing shell 12 away from the workpiece. At this time, the grinding robot 10 grinds the workpiece, and the air blowing shell 12 does not obstruct or block the grinding robot 10.

[0071] After grinding, when the sides of the workpiece need to be cleaned with air, the lifting unit lowers the second wedge block 1815 and the air strip shell 12 to a low position, bringing the air strip shell 12 closer to the workpiece. Simultaneously, the second wedge block 1815 moves downwards, pushing against the first wedge block 1814. This causes the first wedge block 1814 to move the movable seat 1812. The movable seat 1812, through the connecting shaft 1816, moves the round shaft 1801 and the insertion assembly together, causing the insertion post 1808 of one insertion assembly to engage with the end plate 1802 at the rotating round tube 804. The arc-shaped groove 18021 separates, and the insertion post 1808 of another insertion component is inserted into the arc-shaped groove 18021 on the end plate 1802 at the rotating cylinder 1704 or pressed against the non-arc-shaped groove 18021 on the end plate 1802. During the above process, the movable seat 1812 slides with the guide post 1811, and the square post 1807 slides with the square hole on the rotating sleeve 1806 (the square post 1807 moves into the rotating sleeve 1806, and the telescopic shaft retracts), while compressing the second spring 1805 and the fourth spring 1813; the subsequent drive mechanism 14 drives the entire When the switching mechanism 18 rotates, and the insert 1808 is inserted into the arc-shaped groove 18021 on the end plate 1802 of the rotating drum 1704, after the insert 1808 is in contact with the wall of the arc-shaped groove 18021, the switching mechanism 18 continues to rotate, and the insert 1808 pushes against the wall of the arc-shaped groove 18021, causing the rotating drum 1704 to rotate; when the insert 1808 is pressed against the non-arc-shaped groove 18021 on the end plate 1802 (the insert 1808 is slidably installed with the outer cylinder 1804 and a third spring 1809 is provided), the insert 1808 presses against the end plate 1802. During the process, the insert post 1808 moves into the outer cylinder 1804 and compresses the third spring 1809. The switching mechanism 18 rotates, and the insert post 1808 performs a circular motion, moving to the arc groove 18021. The pressure post 1706 loses the obstruction of the end plate 1802. Through the elastic force of the third spring 1809, the insert post 1808 is inserted into the arc groove 18021. It continues to rotate, and the insert post 1808 fits against the wall of the arc groove 18021. Finally, the insert post 1808 pushes against the wall of the arc groove 18021, causing the rotating cylinder 1704 to rotate.

[0072] After the workpiece is cleaned by air blowing, the lifting part raises the second wedge block 1815 and the air blowing strip shell 12 to a high position, and the air blowing strip shell 12 moves away from the workpiece. The switching mechanism 18 is reset by the elastic force of the fourth spring 1813 and the second spring 1805, and returns to the position where the insertion assembly is inserted into the arc groove 18021 on the end plate 1802 of the rotating round tube 804, or the insertion post 1808 is pressed against the non-arc groove 18021 of the end plate 1802. When the driving mechanism 14 drives the switching mechanism 18 to rotate, the insertion post 1808 is in contact with the wall of the arc groove 18021, which can drive the rotating round tube 804 to rotate.

[0073] It should be noted that the corrugated hose 1701 is made of rubber and is telescopic, suitable for the up and down movement of the air strip housing 12.

[0074] Through the above design, the lifting unit and the pushing unit of the switching mechanism 18 are linked. After the workpiece is ground, the lifting unit moves the air blowing shell 12 closer to the workpiece, and at the same time, it drives the switching mechanism 18 to connect with the air supply mechanism 17. The driving mechanism 14 drives the air supply mechanism 17 to supply air to the air blowing shell 12. When the workpiece needs to be ground, the lifting unit moves the air blowing shell 12 away from the workpiece, and at the same time, it connects the switching mechanism 18 with the chip conveyor 8. The driving mechanism 14 drives the chip conveyor 8 to discharge the chips generated during grinding to the outside of the grinding chamber 2. This makes the switching connection of the switching mechanism 18 require no additional power components.

[0075] like Figures 7-8 as well as Figure 12 As shown, the lifting unit includes a third cylinder 15 fixed to the outer wall of the side shell 13; the output shaft of the third cylinder 15 is fixed with a movable frame 16, and the movable frame 16 is fixed to the air blowing shell 12 and the second wedge block 1815. The air blowing shell 12 has a groove for the movable frame 16 to pass through.

[0076] like Figures 7-8 As shown, the drive mechanism 14 includes a second motor 1401 and a second pulley 1403; the second motor 1401 is fixed on the base plate 1, the output shaft of the second motor 1401 is fixed with a first pulley 1402, a belt 1404 is wound between the first pulley 1402 and the second pulley 1403, and the second pulley 1403 is fixedly sleeved with a rotating sleeve 1806; it also includes a protective cover 9, which is fixed to the base plate 1, and the protective cover 9 covers the first pulley 1402, the second pulley 1403 and the belt 1404 for protection, and the rotating sleeve 1806 is rotatably installed inside the protective cover 9.

[0077] The second motor 1401 drives the first pulley 1402 to rotate, and through the belt 1404, the second pulley 1403 and the rotating sleeve 1806 rotate together. When the rotating sleeve 1806 rotates, the square column 1807 connected to it also rotates, which in turn drives the round shaft 1801 and the plug-in assembly to rotate.

The protection scope of this invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of this invention, but all such changes and modifications shall fall within the protection scope of this invention.
