Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, and in particular to a waste recycling device for expanding holes in parts. Background Technology

[0002] In many fields such as modern machinery manufacturing, automotive industry, and aerospace, the machining accuracy and quality of parts play a crucial role in the performance and reliability of products. Hole expansion, as a common part machining process, is mainly used to enlarge the diameter of existing holes to meet specific assembly or usage requirements. In the manufacturing process of automobile engines, some holes on the cylinder block need to be expanded to ensure the precise installation of components such as pistons and valves. In the aerospace field, expanding holes on aircraft structural components helps to improve the connection strength and overall performance of parts.

[0003] A Chinese patent with publication number CN222429023U discloses a punching device for processing metal automotive parts. In use, the metal automotive parts to be punched are placed on the worktable, and then the hydraulic cylinder on the L-shaped plate is activated, which drives the punching assembly on the mounting plate to move downward to punch the automotive parts. At the same time, the rack moves downward, which drives the bidirectional threaded rod on the gear to rotate, which drives the fixed block on the threaded block to move, and drives the brush to clean the residual waste on the table. The square hole and the inclined plate allow the waste to fall into the collection box. After the punching is completed, the rack moves upward, which drives the brush on the fixed block to clean the waste on the table again.

[0004] Regarding the aforementioned technologies, since brush cleaning is mainly aimed at the desktop surface, it is difficult to effectively clean the gaps in the workbench, the edges of square holes, and tightly adhered debris. These residual debris cannot fall smoothly into the collection box, resulting in incomplete collection. At the same time, the square holes serve as channels for debris to fall, and when the debris is large or numerous, it is easy for it to accumulate and block the square holes, hindering the normal fall of debris, reducing collection efficiency, and even requiring machine shutdown for cleaning, thus affecting production progress. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a waste recycling device for expanding holes in parts to solve the problem that the residual waste in the existing technology cannot fall into the collection box smoothly, resulting in incomplete collection.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a waste recycling device for expanding holes in parts, including an operating table, an expanding device at the upper end of the operating table, an air blowing device fixedly installed at the lower end of the expanding device, and a cleaning and scraping device fixedly installed at the lower end of the expanding device. The expanding device includes a fixed rod, which is fixedly connected to the operating table, and an expanding machine is slidably installed at the upper end of the fixed rod. The cleaning and scraping device includes a connecting rod, one end of which is fixedly connected to the drive end of the expanding machine, and a connecting column fixedly installed on the lower side of the other end of the connecting rod. A gear rod is fixedly installed at the lower end of the connecting column, and teeth are meshed on the outer side of the gear rod. A forward lead screw is fixedly mounted on one side of the gear. A connecting plate is rotatably mounted on the end of the forward lead screw away from the gear. One end of the connecting plate is fixedly connected to the lower end of the operating table. A second connecting rod is threaded onto the outer side of the forward lead screw. A drive motor is fixedly mounted on the upper end of the second connecting rod. An eccentric wheel is fixedly mounted on the drive end of the drive motor. A fixed shaft is connected to the end of the eccentric wheel away from the drive motor via a movable pin. The fixed shaft is movably connected to the eccentric wheel. A flexible scraper is slidably mounted inside the fixed shaft. A bolt is threaded onto the upper end of the fixed shaft. The lower end of the bolt is rotatably connected to the flexible scraper. A reverse lead screw is fixedly mounted on the other side of the gear. The mechanism on the reverse lead screw... Similar to the mechanism on the forward lead screw, when expanding the hole in a component, the component is placed inside the operating table, and the expanding machine is started. The drive end of the expanding machine moves downward to expand the hole in the component. During the expanding process, splashed debris is initially cleaned by an air blowing device to prevent debris from remaining on the surface of the component and affecting the expanding process. At the same time, as the drive end of the expanding machine moves downward, it drives the connecting column downward. As the connecting column moves downward, it drives the gear rod to mesh and rotate, which in turn drives the forward and reverse lead screws to rotate, causing the two sets of connecting rods to move towards each other in opposite directions. Simultaneously, the drive motor is activated, causing the eccentric wheel to rotate. Since the eccentric wheel is connected to the fixed shaft via a movable pin, when the eccentric wheel moves in a circular motion under the drive motor, the fixed shaft can reciprocate with the movement of the eccentric wheel. This converts the circular motion of the eccentric wheel into the reciprocating linear motion of the fixed shaft, which in turn drives the flexible scraper to reciprocate and move towards one side, scraping away the debris inside the outer casing during the movement. Finally, the debris is discharged and collected. At the same time, the contact tightness between the flexible scraper and the outer casing can be adjusted by adjusting the bolts, thereby ensuring that the flexible scraper and the outer casing table surface always maintain appropriate pressure and improve the cleaning effect.

[0007] Preferably, the operating table includes a housing with two sets of sliding grooves inside, which match the connecting rod 2. The housing also has two sets of collection slots and a circular hole inside, which matches the gear rod. When the connecting rod moves downward, it moves within the circular hole, and then rotates through the gear rod meshing with the gear, thereby driving the forward lead screw and the reverse lead screw to rotate. When the connecting rod 2 moves along the sliding groove, the waste is scraped into the collection slot by a flexible scraper for collection.

[0008] Preferably, a workbench is fixedly installed inside the outer shell. The workbench has a placement slot inside and an exhaust slot at the lower end. The placement slot and the exhaust slot are connected. The lower end of the workbench is connected to an air blowing device. During the process of expanding the holes of the parts, the splashed waste is blown away from the surface of the parts by the air blowing device.

[0009] Preferably, the air blowing device includes an L-shaped connecting rod, with a pressing plate fixedly installed at the lower end of the L-shaped connecting rod. An exhaust shell is slidably installed on the outer side of the pressing plate, and an air bladder is provided inside the exhaust shell. An exhaust port is opened on the outer side of the exhaust shell and is located at the upper end of the worktable. The exhaust port is connected to the air bladder. A connecting pipe is provided at the lower end of the exhaust shell. One end of the connecting pipe is connected to the air bladder, and the other end of the connecting pipe is fixedly installed with an air outlet pipe, which is connected to the exhaust groove. When the L-shaped connecting rod moves downward through the drive end of the expansion machine, the pressing plate presses the air bladder, causing the gas inside the air bladder to be discharged through the exhaust port. This removes the waste generated when the part first starts to expand, preventing the waste from remaining on the surface of the part and affecting the expansion process. At the same time, some gas is discharged through the connecting pipe to blow out the waste at the lower end of the worktable. When the pressing plate moves downward with the expansion machine and descends to the lower end of the expansion machine, all the gas is discharged through the connecting pipe, and the waste is blown out of the collection grooves on both sides of the worktable by the air outlet pipe.

[0010] Preferably, a collection box is slidably provided at the lower end of the outer shell. The collection box is located at the lower end of the chute and the collection trough, and the waste falling from the chute and the collection trough is collected and recycled through the collection box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model proposes a waste chip recovery device for expanding holes in parts. When expanding holes in parts is required, the parts are placed inside the operating table, and the expanding machine is started. The drive end of the expanding machine moves downward to expand the holes in the parts. During the expanding process, the splashed waste chips are initially cleaned by an air blowing device to prevent waste chips from remaining on the surface of the parts and affecting the expanding process. At the same time, as the drive end of the expanding machine moves downward, it drives the connecting column downward. As the connecting column moves downward, it drives the gear rod to mesh and rotate, which in turn drives the forward lead screw and the reverse lead screw to rotate, causing the two sets of connecting rods to move closer to each other. The system moves while simultaneously activating the drive motor, causing the eccentric wheel to rotate. Since the eccentric wheel is connected to the fixed shaft via a movable pin, as the eccentric wheel moves in a circular motion under the drive motor's influence, the fixed shaft reciprocates with the eccentric wheel's movement. This converts the eccentric wheel's circular motion into the fixed shaft's reciprocating linear motion, which in turn drives the flexible scraper to reciprocate and move towards one side, scraping away debris inside the outer casing during the movement. The debris is then discharged and collected. Simultaneously, the contact tightness between the flexible scraper and the outer casing can be adjusted using adjusting bolts, ensuring that appropriate pressure is maintained between the flexible scraper and the outer casing surface, thus improving the cleaning effect.

Detailed Implementation

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0024] According to one embodiment of the present invention, Figure 1 , Figure 3 , Figure 5-7The diagram shows a waste recycling device for expanding holes in parts, including an operating table 1, an expanding device 2 is provided at the upper end of the operating table 1, an air blowing device 3 is fixedly installed at the lower end of the expanding device 2, a cleaning and scraping device 4 is fixedly installed at the lower end of the expanding device 2, the expanding device 2 includes a fixing rod 21, the fixing rod 21 is fixedly connected to the operating table 1, and an expanding machine 22 is slidably installed at the upper end of the fixing rod 21.The cleaning and scraping device 4 includes a first connecting rod 41. One end of the first connecting rod 41 is fixedly connected to the drive end of the expansion machine 22. A connecting column 42 is fixedly installed on the lower side of the other end of the first connecting rod 41. A gear rod 43 is fixedly installed on the lower end of the connecting column 42. A gear 44 is meshed on the outer side of the gear rod 43. A forward lead screw 45 is fixedly installed on one side of the gear 44. A connecting plate 47 is rotatably installed on the end of the forward lead screw 45 away from the gear 44. One end of the connecting plate 47 is fixedly connected to the lower end of the operating table 1. A second connecting rod 451 is threaded onto the outer side of the forward lead screw 45. A drive motor 452 is fixedly installed on the upper end of the second connecting rod 451. An eccentric wheel 453 is fixedly installed at the drive end of the machine. The end of the eccentric wheel 453 furthest from the drive motor 452 is connected to a fixed shaft 454 via a movable pin. The fixed shaft 454 is movably connected to the eccentric wheel 453. A flexible scraper 455 is slidably installed inside the fixed shaft 454. A bolt 456 is threaded onto the upper end of the fixed shaft 454, and the lower end of the bolt 456 is rotatably connected to the flexible scraper 455. A reverse lead screw 46 is fixedly installed on the other side of the gear 44. The mechanism on the reverse lead screw 46 has the same structural composition as the mechanism on the forward lead screw 45. When it is necessary to expand the hole in a part, the part is placed inside the operating table 1, and the hole-expanding machine 22 is started to expand the hole. The drive end of the expansion machine 22 moves downward to expand the hole in the component. During the expansion process, the splashed debris is initially cleaned by the air blowing device 3 to prevent debris from remaining on the surface of the component and affecting the expansion process. At the same time, as the drive end of the expansion machine 22 moves downward, it drives the connecting column 42 to move downward. As the connecting column 42 moves downward, it drives the gear rod 43 and gear 44 to mesh and rotate, which in turn drives the forward lead screw 45 and the reverse lead screw 46 to rotate. This causes the two sets of connecting rods 451 to move towards each other. At the same time, the drive motor 452 is started to drive the eccentric wheel 453 to rotate. Since the eccentric wheel 453 is connected to the fixed shaft by a movable pin... The 454 connection allows the fixed shaft 454 to reciprocate as the eccentric wheel 453 rotates under the drive of the motor 452. This converts the circular motion of the eccentric wheel 453 into the reciprocating linear motion of the fixed shaft 454, which in turn drives the flexible scraper 455 to reciprocate and move towards one side, scraping away debris inside the outer casing 11 and collecting it. The contact tightness between the flexible scraper 455 and the outer casing 11 can be adjusted by the adjusting bolt 456, ensuring that the flexible scraper 455 maintains appropriate pressure on the surface of the outer casing 11 and improving the cleaning effect.

[0025] Combination Figure 1-2 , Figure 5As shown, the operating table 1 includes a housing 11. The housing 11 has two sets of sliding grooves 111 inside, which are matched with the connecting rod 451. The housing 11 also has two sets of collection grooves 112 inside, and a circular hole 113 inside, which is matched with the gear rod 43. When the connecting column 42 moves downward, it moves within the circular hole 113, and then rotates through the meshing of the gear rod 43 and the gear 44, thereby driving the forward lead screw 45 and the reverse lead screw 46 to rotate. When the connecting rod 451 moves along the sliding groove 111, the waste is scraped into the collection groove 112 by the flexible scraper 455 for collection.

[0026] Combination Figure 2-3 As shown, a workbench 13 is fixedly installed inside the outer casing 11. The workbench 13 has a placement slot 131 inside and an exhaust slot 132 at the lower end. The placement slot 131 and the exhaust slot 132 are connected. The lower end of the workbench 13 is connected to the air blowing device 3. During the process of expanding the hole of the parts, the splashed waste is blown away from the surface of the parts by the air blowing device 3.

[0027] Combination Figure 1 , Figure 3-4 As shown, the air blowing device 3 includes an L-shaped connecting rod 31. A compression plate 311 is fixedly installed at the lower end of the L-shaped connecting rod 31. An exhaust housing 32 is slidably installed on the outer side of the compression plate 311. An airbag 33 is disposed inside the exhaust housing 32. An exhaust port 321 is opened on the outer side of the exhaust housing 32. The exhaust port 321 is located at the upper end of the workbench 13 and is connected to the airbag 33. A connecting pipe 331 is provided at the lower end of the exhaust housing 32. One end of the connecting pipe 331 is connected to the airbag 33, and the other end of the connecting pipe 331 is fixedly installed with an air outlet pipe 133, which is connected to the exhaust groove 132. The L-shaped connecting rod 31... As the expansion machine 22 moves downward, the extrusion plate 311 compresses the air bladder 33, expelling the gas inside the air bladder 33 through the exhaust port 321. This removes the waste generated when the part first starts expanding, preventing the waste from remaining on the part surface and affecting the expansion process. At the same time, some gas is discharged through the connecting pipe 331 to blow out the waste at the lower end of the worktable 13. When the extrusion plate 311 moves further down with the expansion machine 22 and descends to the lower end of the expansion machine 22, all the gas is discharged through the connecting pipe 331. The waste is blown through the exhaust pipe 133, agitating the waste at the lower end of the placement trough 131, and blowing it out from the collection troughs 112 on both sides of the worktable 13.

[0028] Combination Figure 2 As shown, a collection box 12 is slidably disposed at the lower end of the outer shell 11. The collection box 12 is located at the lower end of the slide 111 and the collection trough 112. Waste debris falling from the slide 111 and the collection trough 112 is collected and recycled through the collection box 12.

[0029] In this embodiment, when it is necessary to expand the hole in a component, the component is placed in the placement slot 131 on the workbench 13 inside the outer shell 11 of the operating table 1. The expansion machine 22 is started, and the drive end of the expansion machine 22 moves down to expand the hole in the component. During the expansion process, the drive end of the expansion machine 22 moves down, causing the L-shaped connecting rod 31 to move downward. The extrusion plate 311 squeezes the air bladder 33 inside the exhaust shell 32. The gas inside the air bladder 33 is discharged through the exhaust port 321 to remove the waste generated when the component is first expanded, preventing the waste from remaining on the surface of the component and affecting the expansion process. At the same time, some gas is discharged through the connecting pipe 331 and the air outlet pipe 133 to blow out the waste at the lower end of the workbench 13 and the lower end of the placement slot 131, and blown out from the collection slots 112 on both sides of the workbench 13. Meanwhile, the drive end of the expansion machine 22 moves down, causing the connecting column 42 to move downward. The connecting column 42 moves in the round hole 113 and drives the gear rod 43 to mesh with the gear 44. The movement of the flexible scraper 45, in turn, causes the forward lead screw 45 and the reverse lead screw 46 to rotate, making the two sets of connecting rods 451 move along the slide groove 111 towards each other. At the same time, the drive motor 452 is started to drive the eccentric wheel 453 to rotate. Since the eccentric wheel 453 is connected to the fixed shaft 454 through the movable pin, the fixed shaft 454 reciprocates when the eccentric wheel 453 makes a circular motion, converting the circular motion of the eccentric wheel 453 into the reciprocating linear motion of the fixed shaft 454. This, in turn, causes the flexible scraper 455 to reciprocate and move towards each other, scraping away the debris inside the outer shell 11 during the movement and causing it to fall into the collection trough 112. Finally, the debris falling from the slide groove 111 and the collection trough 112 is collected and recycled through the collection box 12 located at its lower end. The contact tightness between the flexible scraper 455 and the outer shell 11 can be adjusted by adjusting the bolt 456, thereby ensuring that the flexible scraper 455 and the table surface of the outer shell 11 always maintain a suitable pressure and improve the cleaning effect.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
