Description

Technical Field

[0001] The invention relates to the technical field of special parts processing, in particular to a highly efficient cutting device for scrapped fan-shaped vibration damping blocks of a high-elastic coupling. Background Art

[0002] In the mechanical transmission system, the high elastic coupling is a key component, and its performance directly affects the operating stability and life of the entire system. The fan-shaped vibration damping block is an important component of the high elastic coupling. Its structural feature is that it is composed of multiple concave and convex fan-shaped metal sheets. This design not only gives the coupling good elastic buffering ability, but also effectively reduces vibration and noise transmission.

[0003] There are two main ways to process fan-shaped vibration damping blocks: one is to directly process cylindrical metal into a fan-shaped structure with a specific concave and convex shape through precision milling technology. Although this method can ensure high processing accuracy, since elastic metal materials are usually expensive and a large amount of metal chips will be generated during the milling process, the material utilization rate is low and nearly half of the material is wasted, which not only increases production costs but also violates the concept of green manufacturing. Another processing method is to use a casting process to inject molten metal into a mold and cool it into shape. Although the casting process can achieve mass production and reduce costs, the scrap rate is high, especially for fan-shaped vibration damping blocks with complex shapes and high precision requirements. It is even more difficult to guarantee the yield rate. Therefore, for scrapped cast vibration damping blocks, further contour trimming is often required to meet the use requirements.

[0004] However, general-purpose machine tool processing equipment has many shortcomings when processing such scrapped fan-shaped vibration damping blocks. First, the processing efficiency is low, and it is necessary to process each one, which is difficult to meet the needs of mass production; second, the processing accuracy is difficult to control, especially when processing complex surfaces and tiny structures, errors are more likely to occur. These problems not only limit the application of general-purpose machine tool processing equipment in the field of fan-shaped vibration damping block repair, but also increase the operating burden and market competitiveness of enterprises.

[0005] Therefore, it is necessary to provide a high-efficiency cutting device for scrapped fan-shaped vibration damping blocks of high elastic couplings that can quickly and accurately trim the contours of scrapped fan-shaped vibration damping blocks, improve material utilization and processing efficiency, and reduce production costs and scrap rates. Using advanced profiling technology and automated control systems, efficient cutting and precise trimming of scrapped fan-shaped vibration damping blocks are achieved, providing strong support for performance improvement and cost control of mechanical transmission systems.

[0014] Profiling assembly, including:

[0015] A contour chuck is rotatably arranged at the center of the base and is used to clamp the vibration damping block sample;

[0016] The annular track is fixed on the center plate and surrounds the through hole of the center plate;

[0017] Two sliders are slidably arranged on the annular track and can be locked;

[0018] The guide rod passes through the two slide blocks and fits into the damping block template on the profiling chuck. By rotating the profiling chuck and lifting the center plate, the guide rod is fit onto the damping block template to guide the cutting path.

[0019] Furthermore, preferably, the processing chuck is a structure with adjustable clamping force.

[0020] Furthermore, preferably, the cutter is a high-speed rotating cutter and is equipped with a coolant spray system.

[0021] Furthermore, as a preference, the center plate is penetrated by a plurality of threaded screws, and the screws are driven to rotate by a servo motor disposed in the base.

[0022] Further, as a preference, a rotating shaft is fixed below each of the processing chucks, the rotating shaft penetrates into the base, and the rotating shaft is fixedly sleeved with a gear in the base;

[0023] A gear ring is rotatably arranged inside the base, and the gear ring is meshed with each of the gears.

[0024] Further, as a preference, a central shaft is fixedly connected to the bottom of the profiling chuck, the central shaft penetrates into the base, and the rotating shaft is sleeved with a central pulley in the base;

[0025] A chuck pulley is provided in the fixed sleeve of one of the rotating shafts;

[0026] The center pulley and the chuck pulley have the same diameter;

[0027] The central pulley and the chuck pulley are connected via a synchronous belt.

[0028] Furthermore, preferably, a driving motor is connected below the central axis.

[0029] Furthermore, preferably, a cover plate is fixed above the vibration damping block template clamped in the contoured chuck.

[0030] Further, as a preference, the central pulley and the central shaft are connected via a first ratchet transmission device, thereby enabling one-way transmission between the central pulley and the central shaft.

[0031] Further, as a preference, the central pulley is fixedly connected to a driven bevel gear;

[0032] A driving bevel gear is connected below the central shaft through a second ratchet transmission device;

[0033] The inner wall of the base is rotatably connected with a side bevel gear, and the side bevel gear is respectively meshed with the driven bevel gear and the driving bevel gear;

[0034] The transmission direction of the second ratchet transmission device is opposite to the transmission direction of the first ratchet transmission device.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] In the present invention, the device, by introducing a profiling component, takes a standard damping block template as a reference, and realizes the simultaneous cutting of the scrapped damping blocks to be processed in multiple processing chucks. Under the precise guidance of the profiling component, the cutter can move along the path of the standard outer contour and accurately repair the scrapped fan-shaped damping blocks. The processing efficiency is significantly improved, the utilization rate of scrapped products is greatly increased, and the waste of resources is reduced.

[0037] In the present invention, the connection design between the center plate and each lifting platform ensures the synchronization and stability of all cutters during the lifting process. At the same time, the processing chuck realizes synchronous rotation through the meshing of the gear and the gear ring, further improving the consistency and accuracy of the processing, simplifying the drive and control structure, reducing maintenance costs, and ensuring the stability of the processing quality.

[0038] In the present invention, since the top of the vibration damping block is open, a cover plate is installed above the vibration damping block template to limit the upper moving space of the guide rod, effectively preventing excessive movement of the guide rod during the cutting process, improving the profiling accuracy, and allowing the cutter to more accurately cut and trim along the contour of the fan-shaped vibration damping block.

[0039] In the present invention, no matter whether the center shaft drives the profiling chuck to rotate forward or reversely, the processing chuck rotates in the forward direction. When the cover plate closes the top of the vibration damping block template, the driving motor drives the profiling chuck to rotate forward and reverse, so that the guide rod only needs to reciprocate in a circle in one of the recesses of the vibration damping block template to make the processing chuck rotate continuously in the forward direction, and cooperate with the lifting and lowering of the center plate to enable the cutter to move along the path of the standard outer contour.

DETAILED DESCRIPTION

[0046] See also Figure 1-Figure 5 In an embodiment of the present invention, a highly efficient cutting device for scrapped fan-shaped vibration damping blocks of a high-elastic coupling comprises:

[0047] Base 1 is a cylindrical support structure used to provide stable support for the entire device;

[0048] A plurality of vertical plates 2 are evenly arranged along the circumferential direction and fixedly connected to the base 1, and together form a ring structure;

[0049] A plurality of lifting platforms 3, each lifting platform 3 is slidably connected to the outer side of the corresponding vertical plate 2, allowing free movement in the vertical direction;

[0050] A plurality of processing chucks 4, each processing chuck 4 is rotatably connected to the base 1 and is arranged at the front end of the corresponding lifting platform 3, and is used to fix the fan-shaped vibration damping block to be processed;

[0051] A plurality of cutters 5, each of which is mounted on a corresponding lifting platform 3 and is in a horizontal state, and performs a cutting operation on a vibration damping block fixed on a processing chuck 4 under power drive;

[0052] The center plate 6 is located inside the annular structure surrounded by the plurality of vertical plates 2, and has a through hole in the middle;

[0053] A plurality of connecting rods 7, wherein the central plate 6 is fixedly connected to each lifting platform 3 through the plurality of connecting rods 7, wherein a through groove is provided at the center of the vertical plate 2, and the connecting rod 7 is slidably arranged in the through groove to ensure synchronization and stability of the lifting platform 3 during the lifting process;

[0054] The profiling component 8 comprises:

[0055] A contoured chuck 81 is rotatably disposed at the center of the base 1 and is used to clamp the vibration damping block sample;

[0056] The annular track 82 is fixed on the center plate 6 and surrounds the through hole of the center plate 6;

[0057] Two sliders 83 are slidably disposed on the annular track 82 and can be locked;

[0058] The guide rod 84 passes through the two sliders 83 and fits into the damping block template on the profiling chuck 81. By rotating the profiling chuck 81 and the lifting center plate 6, the guide rod 84 is fitted above the damping block template to guide the cutting path.

[0059] By rotating the processing chuck 4, the circumferential position of the cutter 5 processing the fan-shaped vibration damping block can be adjusted. Under the guidance of the profiling component 8, the height of the cutter 5 processing the fan-shaped vibration damping block can be adjusted by changing the height of the lifting platform 3, so that the cutter 5 moves along the contours of the recesses and protrusions of the fan-shaped vibration damping block to perform cutting and trimming.

[0060] In this embodiment, the processing chuck 4 is a structure with adjustable clamping force to adapt to fan-shaped vibration-damping blocks of different materials and sizes, ensuring that the vibration-damping blocks remain stable and do not shake during the cutting process.

[0061] In this embodiment, the cutter 5 is a high-speed rotating tool and is equipped with a coolant spray system to reduce the heat and friction generated during the cutting process, extend the service life of the tool and improve the cutting quality.

[0062] In this embodiment, a plurality of threaded screws 61 penetrate the center plate 6 , and the screws 61 are driven to rotate by a servo motor disposed in the base 1 .

[0063] When the height of the lifting platform needs to be adjusted, the servo motor in the base 1 starts and drives the screw 61 to rotate. Since the screw 61 is threadedly connected to the center plate 6, the center plate 6 will move up and down with the rotation of the screw. The movement of the center plate 6 is transmitted to each lifting platform 3 through the connecting rod 7. Since the connecting rod 7 slides in the through groove of the vertical plate 2, the stability and synchronization during the lifting process are ensured.

[0064] See also Figure 5 In this embodiment, a rotating shaft 41 is fixed under each processing chuck 4, and the rotating shaft 41 penetrates into the base 1, and a gear 42 is fixedly sleeved on the rotating shaft 41 in the base 1;

[0065] A gear ring 9 is rotatably disposed inside the base 1 , and the gear ring 9 is meshed with each of the gears 42 .

[0066] That is to say, under the action of the gear ring 9, each gear 42 rotates synchronously, so that each processing chuck 4 also rotates synchronously, ensuring the consistency of processing of the processing chuck 4 and simplifying the driving structure.

[0067] In this embodiment, a central shaft 10 is fixedly connected to the lower side of the profiling chuck 81, and the central shaft 10 penetrates into the base 1. The rotating shaft 41 is sleeved with a central pulley 11 in the base 1.

[0068] A chuck pulley 43 is provided in a fixed sleeve in one of the rotating shafts 41;

[0069] The center pulley 11 and the chuck pulley 43 have the same diameter;

[0070] The center pulley 11 and the chuck pulley 43 are connected via a synchronous belt 12 .

[0071] That is to say, through the connection of the synchronous belt 12, the profiling chuck 81 and each processing chuck 4 rotate synchronously, thereby ensuring the accuracy of the profiling path.

[0072] In this embodiment, a driving motor 13 is connected below the central shaft 10 to drive the contour chuck 81 and each processing chuck 4 to rotate.

[0073] In this embodiment, a cover plate 85 is fixed above the damping block template clamped in the contoured chuck 81. The cover plate 85 closes the damping block template and can limit the upward movement space of the guide rod 84, thereby limiting the guide rod 84 in the notch of the damping block template.

[0074] In this embodiment, the central pulley 11 and the central shaft 10 are connected via a first ratchet transmission device 14 , so that one-way transmission is achieved between the central pulley 11 and the central shaft 10 .

[0075] In this embodiment, the central pulley 11 is fixedly connected to a driven bevel gear 15;

[0076] The central shaft 10 is connected to a driving bevel gear 17 through a second ratchet transmission device 18 below;

[0077] The inner wall of the base 1 is rotatably connected to a side bevel gear 16, and the side bevel gear 16 is respectively meshed with the driven bevel gear 15 and the driving bevel gear 17;

[0078] The transmission direction of the second ratchet transmission device 18 is opposite to the transmission direction of the first ratchet transmission device 14 .

[0079] When the center shaft 10 rotates forward, the center pulley 11 is driven by the first ratchet transmission device 14 to drive each processing chuck 4 to rotate forward, and when the center shaft 10 rotates reversely, the second ratchet transmission device 18 drives the active bevel gear 17, the side bevel gear 16 and the driven bevel gear 15 so that the center pulley 11 still drives each processing chuck 4 to rotate forward. In other words, no matter whether the center shaft 10 drives the contour chuck 81 to rotate forward or reverse, the processing chuck 4 rotates forward. When the cover plate 85 closes the top of the damping block template, the driving motor 13 drives the contour chuck 81 to rotate forward and reverse, and the screw 61 drives the center plate 6 to rotate up and down, so that the guide rod 84 reciprocates in a circular manner in one of the notches of the damping block template, and the processing chuck 4 continues to rotate forward, and the lifting platform 3 moves up and down synchronously with the center plate 6, so that the cutter 5 moves along the contour of the notch and protrusion of the fan-shaped damping block for cutting and trimming.

[0080] When implementing it specifically,

[0081] Clamp the fan-shaped vibration damping block sample of the standard sample on the contoured chuck 81, make the guide rod 84 fit tightly in the notch of the vibration damping block sample, and install the cover plate 85 to close the top of the sample and limit the upper moving space of the guide rod 84;

[0082] Clamp the fan-shaped vibration damping block to be cut on the processing chuck 4, and make the position of the cutter 5 against the fan-shaped vibration damping block to be cut be the same as the position of the guide rod 84 against the sample fan-shaped vibration damping block;

[0083] The servo motor in the base 1 is started to drive the screw 61 to rotate. Since the screw 61 is threadedly connected to the center plate 6, the center plate 6 will move up and down with the rotation of the screw 61. The movement of the center plate 6 is transmitted to each lifting platform 3 through the connecting rod 7;

[0084] At the same time, the driving motor 13 is started, and the profiling chuck 81 and each processing chuck 4 are driven to rotate simultaneously through the connection of the synchronous belt 12, and when the profiling chuck 81 performs forward and reverse reciprocating rotation, the processing chuck 4 continues to rotate forward;

[0085] With the lifting of the center plate 6 and the rotation of the processing chuck 4, the cutter 5 is driven by power to cut and trim along the contours of the recesses and protrusions of the fan-shaped vibration damping block.

[0086] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
