Description

Technical Field

[0001] This invention relates to the field of polishing technology, and in particular to a turbine blade polishing device. Background Technology

[0002] As a core component of aero-engines, the surface finish of turbine blades directly affects their aerodynamic performance and service life. The industry generally uses a vibratory polishing barrel with polishing abrasive to complete the fine polishing treatment of the blade surface. During the operation of existing polishing equipment, blade polishing generates a large amount of metal dust and fine abrasive particles. The dust mixed in with the polishing abrasive continuously adheres to the workpiece surface, which not only reduces the polishing accuracy, but also pollutes the working environment and endangers the health of operators.

[0003] Traditional polishing dust removal often uses a single external dust collection device with a fixed suction port position, making it difficult to fully capture dust from all layers inside the polishing barrel.

[0004] Meanwhile, the debris accumulated in the polishing sand can easily block the material feeding channel. After the sand debris clumps together, it is necessary to stop the machine frequently for manual screening and cleaning, resulting in poor processing continuity.

[0005] Meanwhile, the existing polishing barrel has a simple positioning structure, which is prone to displacement and shaking when rotating at high speed. The blade clamping angle is inconvenient to adjust, and there is a lack of auxiliary load-bearing structure for loading and unloading. Disassembling and assembling the polishing barrel is time-consuming and labor-intensive.

[0006] In addition, conventional dust collection structures can only collect surface dust once, making it difficult to filter debris from polishing sand at different heights in layers. This results in low dust collection efficiency, incomplete separation of dust and sand, poor polishing sand reuse, and significant defects in overall processing efficiency and dust removal and environmental protection performance. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a turbine blade polishing device to solve the technical problems of existing turbine blade polishing devices, such as poor dust collection and filtration, easy displacement of the polishing barrel, easy clogging of sand chips, dust pollution of the environment, poor processing continuity and sand recycling effect.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a turbine blade polishing device, comprising a polishing device body, an inner mounting box installed on the top inner side of the polishing device body, an air pump disposed on the inner wall of the inner mounting box, a bag collection box installed at the output end of the air pump, a dust suction pipe installed at the input end of the air pump, an electric telescopic rod installed at the bottom end of the inner mounting box, a side fixing frame installed at the output end of the electric telescopic rod, a servo cylinder installed on one side of the side fixing frame, and a turbine blade mounting rod installed at the output end of the servo cylinder; a passive dust filter assembly installed at the bottom end of the side fixing frame, the passive dust filter assembly being used to filter dust from the polishing sand inside the polishing assembly; a polishing assembly installed on the bottom inner wall of the polishing device body, the polishing assembly polishing the turbine blades fixed on the turbine blade mounting rod using the internal polishing sand.

[0009] Optionally, the suction pipe passes through the side fixing frame and its end is positioned directly above the passive dust filter assembly, and the surface of the suction pipe is slidably connected to the inner wall of the side fixing frame.

[0010] Optionally, the passive dust filtration assembly includes a dust filtration platform, which is installed at the bottom of the through-side fixing frame. Multiple shovel-shaped rails are inserted into the surface of the dust filtration platform, and multiple dust collection boxes are installed on the top of the dust filtration platform. Multiple discharge holes are opened on the inner side of the dust collection boxes on the surface of the dust filtration platform. A discharge plate is installed on the inner side of the dust collection boxes, and multiple dust collection hoppers are installed on the top of the discharge plate. Multiple stirring rods are installed at the bottom of the dust filtration platform.

[0011] Optionally, the lengths of the multiple shovel box tracks are proportionally from short to long, the dust collection box is located on one side of the top of the shovel box track, and an opening is provided in the gap between the dust collection box and the dust filter platform.

[0012] Optionally, the dust collection hopper is crescent-shaped, the stirring rod is arc-shaped and multiple stirring rods are symmetrically arranged, and the bottom opening of the suction pipe is adjacent to the top of the unloading plate.

[0013] Optionally, the polishing assembly includes a drive platform, which is installed on the bottom inner side of the polishing equipment body, and a triangular bracket is installed at the output end of the drive motor built into the drive platform.

[0014] Optionally, a telescopic loading platform is nested in the inner wall of the front end of the drive platform, and a top seat is installed on the top of the drive platform, with a positioning groove opened at the top front end of the top seat.

[0015] Optionally, the polishing assembly further includes a polishing barrel, a side seat is installed at the bottom of the polishing barrel, a roller is rotatably connected to the outer side of the side seat, a rotating seat is installed at the center bottom of the polishing barrel, a triangular bracket is fixedly installed at the bottom of the polishing barrel, and the side seat is positioned above the top seat.

[0016] Optionally, a side slide rail is installed on the inner wall of the front end of the polishing equipment body. The side slide rail is configured as two sets, and a limit rod is slidably installed on the inner wall of the two sets of side slide rails.

[0017] Optionally, the bottom of the limiting rod has the same shape as the top of the positioning groove, the second triangular bracket is rotatably inserted into the surface of the rotating base, and the first and second triangular brackets are both set to triangular rhombus shape and are detachably meshed with each other.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] The above solution features a suction pipe that can rise and slide synchronously with the electric telescopic rod, paired with a layered passive dust filtration system. Multiple sets of shovel tracks of varying lengths are also included to capture dust and debris from polishing abrasive at different depths. A stirring rod continuously agitates the abrasive to prevent debris from clumping and clogging the discharge hole. A crescent-shaped dust collection hopper buffers debris and dust, reducing their flow rate. An air pump, in conjunction with a bag filter, collects floating dust, achieving efficient separation of polishing abrasive and dust. This significantly improves dust removal efficiency, reduces dust pollution in the workshop, and improves the working environment. The polishing abrasive, after impurity removal, can be recycled multiple times, eliminating the need for frequent machine shutdowns for manual sieving and cleaning. This effectively ensures continuous polishing operation, increases overall processing capacity, and guarantees the cleanliness of the polishing abrasive.

[0020] The polishing barrel is easily pushed and pulled for loading and unloading using rollers and a telescopic loading platform. The triangular bracket two at the bottom of the barrel and the triangular bracket one on the drive platform can quickly engage for transmission. The side slide rail and limit rod, together with the top seat positioning groove, axially lock the polishing barrel, effectively limiting the barrel's offset and sway during high-speed rotation. The transmission structure is easy to assemble and disassemble, and the positioning is stable and reliable. At the same time, the servo cylinder can flexibly adjust the turbine blade mounting rod angle, significantly reducing manual operation intensity and improving the equipment's material changing efficiency. The triangular bracket has a triangular rhomboid detachable meshing structure with a self-centering effect, making assembly and alignment simple. It has a large meshing contact surface, stable torque transmission, and is not prone to slippage or disengagement during high-speed rotation. The circumferential limit suppresses the polishing barrel's sway and sway. The easy disassembly and separation simplify the loading and unloading process of the polishing barrel and reduce maintenance and replacement costs.

[0021] This complete set of equipment integrates blade clamping, lifting and adjustment, polishing drive, layered dust filtration, and dust collection functions into one unit. The electric telescopic rod synchronously drives the blades and dust filtration structure to rise and fall in sync. The suction port is always aligned with the dust collection box above the rotating polishing barrel, eliminating the need for separate adjustment of the suction position. All components are integrated and arranged based on the main body of the equipment, resulting in a compact structure. The transmission and dust filtration components work together to passively capture dust and debris from polishing sand at different depths, saving multiple manual cleaning and alignment processes. The overall polishing efficiency is significantly improved. The dust collection box can be pulled out along the shovel box track to clean accumulated sand, and the bag collection box can be disassembled and emptied of dust independently. Disassembly and maintenance are simple, improving polishing quality, dust removal effect, and production efficiency. Attached Figure Description

[0035] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0036] like Figures 1 to 11 As shown, an embodiment of the present invention provides a turbine blade polishing device, including a polishing device body 1. An inner mounting box 10 is installed on the inner side of the top of the polishing device body 1. An air pump 11 is provided on the inner wall of the inner mounting box 10. A bag collection box 12 is installed at the output end of the air pump 11. A dust suction pipe 13 is installed at the input end of the air pump 11. An electric telescopic rod 14 is installed at the bottom end of the inner mounting box 10. A side fixing frame 17 is installed at the output end of the electric telescopic rod 14. A servo cylinder 15 is installed on one side of the side fixing frame 17. A turbine blade mounting rod 16 is installed at the output end of the servo cylinder 15. A passive dust filter assembly 2 is installed at the bottom end of the side fixing frame 17. The passive dust filter assembly 2 is used to filter dust from the polishing sand in the polishing assembly 4. A polishing assembly 4 is installed on the inner wall of the bottom of the polishing device body 1. The polishing assembly 4 passes through an inner... The polishing abrasive in the part polishes the turbine blades fixed on the turbine blade mounting rod 16. The suction pipe 13 passes through the side fixing frame 17 and its end is positioned directly above the passive dust filter assembly 2. The surface of the suction pipe 13 is slidably connected to the inner wall of the side fixing frame 17. The side fixing frame 17, the suction pipe 13, the passive dust filter assembly 2 and the turbine blades can be raised and lowered synchronously through the electric telescopic rod 14. The suction pipe 13 slides relative to the side fixing frame 17, always keeping the suction port facing the dust filter operation area. The air pump 11 works with the bag collection box 12 to suck up the dust generated during polishing in real time. The servo cylinder 15 can adjust the angle of the turbine blade mounting rod 16 to adapt to the multi-angle polishing needs of the blades. The overall container layout is compact, and the polishing, dust removal and workpiece loading and adjusting actions are linked and synchronized. There is no need to adjust the position of the suction and the workpiece separately, and the operation is more continuous.

[0037] like Figures 1 to 7As shown, the passive dust filtration assembly 2 includes a dust filtration platform 20, which is installed at the bottom of the through-side fixing frame 17. Multiple shovel-shaped rails 21 are inserted into the surface of the dust filtration platform 20. Multiple dust collection boxes 22 are installed on the top of the dust filtration platform 20. Multiple discharge holes 23 are opened on the inner side of the dust collection boxes 22 on the surface of the dust filtration platform 20. A discharge plate 24 is installed inside the dust collection box 22, and multiple dust collection hoppers 25 are installed on the top of the discharge plate 24. Multiple stirring rods 26 are installed at the bottom of the dust filtration platform 20. The lengths of the multiple shovel-shaped rails 21 are proportionally increasing from short to long. The dust collection boxes 22 are positioned on one side of the top of the shovel-shaped rails 21. The space between the dust collection boxes 22 and the shovel-shaped rails 21 in the dust filtration platform 20 is... An opening is provided in the gap, the dust collection hopper 25 is set in a crescent shape, the stirring rod 26 is set in an arc shape and multiple stirring rods 26 are symmetrically arranged, the bottom opening of the suction pipe 13 is adjacent to the top of the unloading plate 24, the polishing sand of different depths inside the polishing bucket 43 can be scooped up in layers through the shovel box track 21 arranged in different lengths, the crescent-shaped dust collection hopper 25 buffers the airflow of sand and dust falling, reducing the dust diffusion speed, the symmetrical arc-shaped stirring rod 26 rotates with the bucket to stir the accumulated sand, preventing the discharge hole 23 from being blocked by dust agglomeration, after the light dust is adsorbed by the suction pipe 13, the clean polishing sand falls into the dust collection box 22 through the discharge hole 23 for temporary storage, realizing the separation of sand and dust in layers, improving dust removal efficiency and reducing the frequency of downtime for sand cleaning.

[0038] like Figures 8 to 11 As shown, the polishing assembly 4 includes a drive platform 40, which is installed on the bottom inner side of the polishing equipment body 1. A triangular bracket 400 is installed at the output end of the drive motor built into the drive platform 40. A telescopic feeding table 41 is nested in the inner wall of the front end of the drive platform 40. A top seat 42 is installed on the top of the drive platform 40. A positioning groove 420 is opened on the top front end of the top seat 42. The polishing assembly 4 also includes a polishing barrel 43. A side seat 44 is installed at the bottom of the polishing barrel 43. A roller 45 is rotatably connected to the outer side of the side seat 44. A rotating seat 4 is installed at the center bottom of the polishing barrel 43. 6. A triangular bracket 47 is fixedly installed at the bottom of the polishing barrel 43, and a side seat 44 is set above the top seat 42. The telescopic loading platform 41, together with the rollers 45, can easily push and pull the polishing barrel 43 for transport. The rotating seat 46 is detachably connected to the top seat 42 to realize the quick positioning and placement of the polishing barrel 43. The triangular diamond meshing structure of the triangular bracket 400 and the triangular bracket 47 has a self-centering function, a large transmission contact area, and smooth torque transmission without slippage under high-speed rotation. Together with the top seat 42 and the positioning groove 420, a double limit is formed to suppress the rotational deviation and shaking of the polishing barrel 43 and ensure the uniformity of blade polishing.

[0039] like Figure 8As shown, a side slide rail 48 is installed on the inner wall of the front end of the polishing equipment body 1. The side slide rail 48 is configured in two sets, and a limit rod 49 is slidably installed on the inner wall of the two sets of side slide rails 48. The bottom of the limit rod 49 has the same shape as the top of the positioning groove 420. The second triangular bracket 47 is rotatably inserted into the surface of the rotating base 46. The first triangular bracket 400 and the second triangular bracket 47 are both triangular rhomboid in shape and are detachably meshed with each other. The limit rod 49 slides vertically along the side slide rail 48 and is engaged after moving down. The slot 420 presses against the side seat 44, axially locking the polishing barrel 43 to prevent it from moving during rotation. The triangular diamond-shaped clasp is easy to assemble and disassemble, and the polishing barrel 43 can be directly removed after separation, simplifying the loading and unloading process. The triangular structure has high support strength and is not easily deformed or worn during long-term heavy-load rotation, reducing the cost of parts replacement and equipment maintenance. The triangular clasp 400 and triangular clasp 47 are made of wear-resistant alloy steel with extremely high hardness and wear resistance, with almost no wear, making them suitable for long-term uninterrupted operation.

[0040] The working principle of the technical solution provided by this invention is as follows:

[0041] First, when the polishing equipment body 1 is in operation, the turbine blade to be processed is clamped on the turbine blade mounting rod 16. The servo cylinder 15 drives the turbine blade mounting rod 16 to complete the angle adjustment. The electric telescopic rod 14 drives the side fixing frame 17 and the overall passive dust filter assembly 2 below to move downward, so that the turbine blade extends into the polishing barrel 43 inside the polishing assembly 4. The bottom of the polishing barrel 43 is detachably mounted on the top seat 42 above the drive platform 40 through the rotating seat 46. The rollers 45 mounted on the outside of the side seat 44 support the polishing barrel 43 for easy pushing, pulling and unloading.

[0042] Simultaneously, polishing sand is put into the polishing bucket 43, and the telescopic loading platform 41 is pulled out. The operator pushes the polishing bucket 43 forward on the telescopic loading platform 41 via the bottom roller 45 until the triangular bracket 2 47 at the bottom of the polishing bucket 43 meshes with the triangular bracket 1 400 at the output end of the drive motor built into the drive platform 40. The top seat 42 lifts up the roller 45 at the bottom of the polishing bucket 43, so that it stops rolling. At the same time, the top seat 42 and the side seat 44 bite each other tightly to increase the friction.

[0043] Then, the limiting rods 49, which are slidably installed in the two sets of side slide rails 48 at the front end of the polishing equipment body 1, are manually moved down. Their bottoms match and engage with the top positioning groove 420 of the top seat 42. The limiting rods 49 are tightly abutted against the front end of the side seat 44, which axially limits the rotating seat 46 and the polishing barrel 43 to prevent the polishing barrel 43 from shifting during the polishing process.

[0044] Subsequently, the drive platform 40 has a built-in drive motor output end connected to a triangular bracket 400, and a triangular bracket 47 is set at the bottom of the polishing barrel 43. Both are triangular rhomboid and are detachably meshed. The drive motor drives the polishing barrel 43 to rotate as a whole through the interlocking triangular brackets 400 and 47. The polishing sand in the barrel continuously rubs against the surface of the turbine blades to achieve the polishing operation.

[0045] When the polishing sand needs to be replaced, the telescopic loading platform 41 nested at the front end of the drive platform 40 can be extended to assist the operator in loading and unloading the polishing barrel 43 and turbine blades.

[0046] When the dust and debris generated during polishing fall into the polishing sand in the polishing bucket 43, the air pump 11 on the inner wall of the inner mounting box 10 is started simultaneously during the polishing operation. The input end of the air pump 11 is connected to the suction pipe 13. The suction pipe 13 passes through the side fixing frame 17 and can slide relative to the inner wall of the side fixing frame 17. The bottom opening of the suction pipe 13 is located adjacent to the top of the unloading plate 24 in the passive dust filter assembly 2 and directly above the dust filter table 20. The dust and fine sand generated during polishing are passively scooped up in the polishing bucket 43 by the shovel box track 21. After floating upwards, they first fall into the top of the crescent-shaped dust collection hopper 25 at the top of the dust filter table 20. The dust collection hopper 25 decelerates the dust and polishing sand. At this time, when the debris and polishing sand are received by the unloading plate 24, when the polishing bucket 43 rotates to directly below the suction pipe 13, the dust collection box 22, which is filled with high-speed suction, will be sucked up by the high-speed wind generated by the suction pipe 13 at the output end of the air pump 11 because the dust and fine sand are relatively light.

[0047] At this point, the polishing sand, after being vacuumed, falls into the dust collection box 22 through multiple discharge holes 23 on the dust filter table 20, and continues polishing.

[0048] Multiple shovel tracks 21 of equal length are inserted into the surface of the dust filter table 20, which can collect polishing sand of different heights upwards and remove dust and chips. The dust collection box 22 is arranged on one side of the top of the shovel track 21. The dust filter table 20 has a reserved opening in the gap between the two to assist in the diversion and collection of debris. Multiple arc-shaped stirring rods 26 are symmetrically installed at the bottom of the dust filter table 20. At the same time, the reaction force generated by the rotation of the polishing barrel 43 makes the stirring rods 26 stir the sand and dust accumulated below, so as to prevent the sand and chips from clumping and blocking the discharge hole 23.

[0049] The air pump 11 continuously sucks up the dust floating above the dust filter table 20 through the suction pipe 13. The dust-laden airflow is delivered to the bag collection box 12 connected to the output end of the air pump 11 to complete the dust filtration and interception. After the polishing process is completed, the air pump 11 continues to suck up dust for a period of time to remove the residual dust.

[0050] The side fixing frame 17, passive dust filter assembly 2 and polished turbine blades are raised by the electric telescopic rod 14. The limit rod 49 slides upward along the side slide rail 48 away from the positioning groove 420 to release the lock on the polishing barrel 43. The engagement between the triangular bracket 1 400 and the triangular bracket 2 47 is broken, and the polishing barrel 43 can be pushed out from the top seat 42 by the roller 45.

[0051] Operators can clean the filtered dust by opening the bag collection box 12, and remove the turbine blade mounting rod 16 to take off the polished turbine blade. In the next round of polishing, the telescopic loading table 41 can be pulled out to assist in the loading and resetting of the new blade and the polishing barrel 43, and the next round of turbine blade polishing can be carried out in a cycle.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
