Description

Technical Field

[0001] This utility model relates to the field of butterfly spring technology, and more specifically, to a feeding device for butterfly springs. Background Technology

[0002] The disc spring in a car is a core component of the clutch system. Its shape is like a thin disc. The disc spring integrates two functions: pressing and disengaging. When the clutch is engaged, the elasticity of its conical part presses the pressure plate tightly against the flywheel, thereby transmitting the engine's power. When the driver depresses the clutch pedal, the release bearing presses against the center of the spring, causing its edge to tilt back and release the pressure on the pressure plate, thereby interrupting the power transmission.

[0003] Currently, existing butterfly spring clamping fixtures typically use suction cups to fix the butterfly springs. The fixture moves downwards, the suction cup contacts the surface of the butterfly spring and a vacuum is drawn to achieve adsorption. After moving to the processing station, the vacuum is released to complete the placement.

[0004] However, this method requires a high degree of surface smoothness of the disc spring. If there is oil or slight deformation on the surface, it is easy to cause poor adhesion, resulting in positioning deviation or even workpiece falling off, affecting processing accuracy and production safety. Furthermore, since there is a slight gap between the disc spring and the workstation after the vacuum is released during placement, it is difficult to align accurately, leading to reduced assembly efficiency.

[0005] To address the above problems, this utility model proposes a feeding device for disc springs. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A feeding device for a disc spring includes a transfer mechanism and a feeding mechanism disposed on the side of the transfer mechanism. The feeding mechanism is equipped with a clamping mechanism, which includes a telescopic cylinder and a servo motor. A drive module is installed at the output end of the servo motor. The output end of the telescopic cylinder is in contact with the upper surface of the drive module. A pair of clamping assemblies are installed below the drive module. Each clamping assembly includes a clamping rod, which is fixed to the drive module. Two connecting bolts are provided on the clamping rod, and rotating clamping blocks are rotatably installed below each connecting bolt. The feeding mechanism includes a feeding electric cylinder. A slide groove is provided on one side of the feeding electric cylinder. A slide table is slidably disposed on the slide groove. A fixed plate is installed on the slide table, and a support platform is provided on the fixed plate.

[0008] The present invention is further configured such that: the material transfer mechanism includes a material transfer connecting shaft, and an upper fixing plate is installed above the material transfer connecting shaft.

[0028] Please see Figure 1-5 The present invention provides the following technical solution: To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] See Figure 1 A rolling device for a disc spring includes an installation mechanism. An upper surface processing mechanism and a side processing mechanism are respectively installed on the upper two sides of the installation mechanism. A transmission mechanism is installed at the front end of the installation mechanism. A clamping mechanism 5 is provided on the transmission mechanism. A support mechanism 8 is provided on one side of the installation mechanism. A material transfer mechanism 7 is rotatably installed on the support mechanism 8. A disc spring 9 is provided on the material transfer mechanism 7. A feeding mechanism 6 is installed on the side wall of the installation mechanism.

[0030] The mounting mechanism presses the disc spring 9. Under normal conditions, due to the special shape of the disc spring 9, direct processing would cause the position to shift, leading to processing accidents. The mounting mechanism fixes the position of the disc spring 9 to avoid accidents during processing. After pressing the disc spring 9. The upper surface processing mechanism moves towards the butterfly spring 9 and rolls the upper surface of the butterfly spring 9 to make it smoother. While the upper surface processing mechanism is processing the butterfly spring 9, the side processing mechanism moves towards the butterfly spring 9 and rolls the side surface of the butterfly spring 9 to make it smoother. Under normal conditions, the workpiece butterfly spring 9 is placed on the transfer mechanism. The transfer mechanism rotates and moves to the loading position, and then moves to the position of the butterfly spring 9 through the transmission mechanism. The clamping distance is adaptively set according to the size of the butterfly spring 9. The loading mechanism moves the butterfly spring 9 upward to the clamping position. The transmission mechanism adjusts the distance to clamp the butterfly spring 9 and moves it to the processing position of the mounting mechanism. After processing, the transmission mechanism moves the processed butterfly spring 9 to the side of the mounting mechanism away from the transfer mechanism.

[0031] Furthermore, a feeding mechanism, a transferring mechanism, and a support mechanism can be set on both sides of the installation mechanism to complete the feeding and unloading of the disc spring 9.

[0032] Referring to Figures 1 and 2, the installation mechanism includes a support base, a rotating component installed inside the support base, a support member installed above the support base, a pressing component and a blowing component respectively installed on the support member, and a protective plate rectangularly installed above the support base.

[0033] The support base provides the installation position and support. The rotating component rotates the disc spring 9 within the support base, allowing the upper surface processing mechanism and the side processing mechanism to process the disc spring 9 without rotating. The support component provides the installation position and positioning effect from above. The pressure component presses the disc spring 9, and the bottom of the pressure component can rotate with the rotating component, achieving the effect that the upper surface processing mechanism and the side processing mechanism can still process the disc spring 9 even when pressed. When the pressing end of the pressure component is lifted, the rotating component still has inertial force. Under normal circumstances, there is a risk that the disc spring 9 will fly out. The blowing component blows downward air onto the disc spring 9 to prevent the disc spring 9 from flying out due to inertial force, and can also blow away excess rolling oil on the surface of the disc spring 9. The protective plate places flying debris and flying oil from the processing of the disc spring 9 during the entire rolling process, playing a protective role.

[0034] The support base includes a base body, an installation groove inside the base body, a fixing platform on the inner wall of the installation groove, and a connection hole on the top of the base body.

[0035] The base body provides the installation position and support, positions the overall rolling mechanism, the mounting slot provides the installation position for the rotating component, the drive part output by the rotating component extends out from the connection hole, and the fixing table fixes the position of the rotating component.

[0036] The rotating assembly includes a rotating motor and a driven disk. A fixed part is installed on the side wall of the rotating motor, and a driving disk is installed at the output end of the rotating motor. A transmission belt is fitted on the driven disk and the driving disk. A connecting shaft is provided on the driving disk, and a fixed disk is fixed on the connecting shaft.

[0037] The output end of the rotary motor rotates, which drives the active disc to rotate. The transmission belt transmits the rotational power of the active disc to the driven disc. When the driven disc rotates, it synchronously drives the connecting shaft to rotate. The connecting shaft rotates synchronously with the fixed disc. The fixed part is fixed on the fixed platform to prevent the rotary motor from shaking during the driving process. The lower end of the connecting shaft passes through the connecting hole and connects to the driven disc. The connecting hole and the connecting shaft are rotatably set.

[0038] The supporting component includes a pressing and fixing body, an upper mounting platform is installed on the pressing and fixing body, a pressing hole is provided on the upper mounting platform, a pressing groove is installed on the side wall of the pressing and fixing body, and a pressing slider is slidably installed on the pressing groove.

[0039] The pressing and fixing body provides a positioning position on the support base, and provides an installation position for the upper mounting platform and the pressing slide. The position of the pressing assembly is supported by the setting of the upper mounting platform and the pressing slider, and the pressing slider slides on the pressing slide.

[0040] The pressing assembly includes a pressing cylinder. The output end of the pressing cylinder is sequentially equipped with a connecting plate, a connecting piece, and a pressing piece. A displacement gauge is installed on the side wall of the connecting piece.

[0041] The pressure cylinder drives the pressure component downward to press the disc spring 9. The pressure cylinder is fixed on the upper mounting platform. The output end of the pressure cylinder passes through the upper mounting platform and connects to the connecting plate. When the output end of the upper mounting platform moves downward, it synchronously drives the connecting plate, connecting component, and pressure component downward until the fixed plate and the pressure component cooperate to press the disc spring 9. The connecting component is fixed to the pressure slider. During the downward process, the downward deviation caused by a single support point is avoided. During the downward process, the displacement gauge measures the falling distance and records it in real time. The whole process is monitored and the falling height is adjusted uniformly.

[0042] The blowing assembly includes a multi-section pipe and a blowing fixture. The blowing fixture is fixed to the side wall of the support member. The multi-section pipe is located in the middle of the blowing fixture, and an air knife is installed at the lower end of the multi-section pipe.

[0043] The multi-section tube supplies air to the air knife. The air is transported through the multi-section tube via an external air supply device. The front end of the multi-section tube is fixed by the blowing fixture to fix the air supply position and prevent the multi-section tube from moving around in the device due to the gas, which could cause processing failure.

[0044] After the disc spring 9 is processed, the rotating motor stops, but there is still inertial force on the connecting shaft and the fixed plate, and this force will be transmitted to the disc spring 9. In this case, the disc spring 9 will fly out due to inertial force. At this time, the air knife blows air onto the workpiece, presses the workpiece down, and counteracts the inertial force that still exists after the rotation stops.

[0045] Referring to Figures 1 and 2, the transmission mechanism includes a first transmission component, a displacement support component, and a second transmission component. The first transmission component and the second transmission component are respectively installed on both sides of the displacement support component, and a clamping mechanism is installed below both the first transmission component and the second transmission component.

[0046] The first transmission component is fixed on the upper mounting platform by a rectangular block. The first transmission component and the second transmission component are used for loading and unloading, respectively. When loading, the first transmission component moves to the loading position to clamp and load the material, while the second transmission component moves to the pressing position to pick up and unload the material. This is done synchronously to improve production efficiency.

[0047] The first transmission assembly includes a drive motor, a sliding mounting plate is provided below the drive motor, the drive motor is fixed on the sliding mounting plate, a transmission wheel is installed at the output end of the drive motor through the upper end of the sliding mounting plate, and a fixed connecting plate is installed on the sliding mounting plate.

[0048] The output of the drive motor rotates, causing the transmission wheel to rotate. A rectangular groove is provided on the side wall of the sliding mounting plate, which is adapted to the transmission wheel. The sliding mounting plate provides the installation position. The fixed connecting plate is connected to the sliding mounting plate to facilitate the fixing of other components. The structure of the second transmission assembly is the same as that of the first transmission assembly.

[0049] The displacement support assembly includes a displacement support body, a transmission rack and a displacement guide rail installed sequentially on one side of the drive motor, and a displacement slider slidably mounted on the displacement guide rail.

[0050] The displacement support body is used for fixed installation. The displacement support body is fixed on the upper mounting platform by a rectangular block. The tooth pitch on the transmission rack is adapted to the transmission wheel. The sliding mounting plate is fixed on the displacement slider. When the output end of the drive motor rotates, the transmission wheel meshes with the transmission rack, thereby causing the sliding mounting plate to slide on the displacement guide rail through the displacement slider. It moves to the loading position and the placement position on the displacement guide rail. The second transmission component is set with the same shape to achieve movement to the unloading position and the placement position.

[0051] Referring to Figures 1 and 2, the upper surface machining mechanism includes a first upper surface drive assembly, a second upper surface drive assembly slidably mounted on the first upper surface drive assembly, and an upper surface machining tool slidably mounted on the second upper surface drive assembly.

[0052] The first drive assembly drives the second drive assembly to move axially, and the second drive assembly drives the upper surface machining tool to move radially, and the upper surface machining tool rolls the workpiece.

[0053] The first drive assembly on the upper surface includes a first processing and fixing plate, which is fixed to the side wall of the support member. An axial drive motor is mounted on the first processing and fixing plate. An axial connecting screw is mounted on the output end of the axial drive motor. An axial moving table is adapted to be mounted on the axial connecting screw. Axial guide rails are provided on both sides of the axial connecting screw. An axial slide table is slidably provided on the axial guide rails.

[0054] The axial moving table is equipped with a thread that matches the axial connecting screw. When the output end of the axial drive motor rotates, it drives the axial connecting screw to rotate. The second drive assembly on the upper surface is fixed to the axial slide and the axial moving table. When the axial connecting screw rotates, it drives the axial moving table and the axial slide to slide. When the axial drive motor rotates forward, it drives the axial moving table and the axial slide to move downward. When the axial drive motor rotates in reverse, it drives the axial moving table and the axial slide to move upward.

[0055] The second drive assembly on the upper surface includes a radial mounting plate, which is fixed to an axial moving table and an axial slide. A radial drive motor is mounted on the radial mounting plate, and the output end of the radial drive motor passes through the radial mounting plate and is connected to a radial lead screw. Radial guide rails are provided on both sides of the radial lead screw, and a radial slide is slidably mounted on the radial guide rails.

[0056] The radial mounting plate provides the mounting position. The output end of the radial drive motor rotates, which drives the radial lead screw to rotate. The upper surface machining tool is fixed on the radial moving table and the radial slide. When the radial lead screw rotates, the radial moving table moves on the radial lead screw, which synchronously drives the radial slide to move. In this way, the upper surface machining tool can be moved to a radial position according to the forward and reverse rotation of the radial drive motor.

[0057] The upper surface machining tool includes an upper surface fixing component, which is fixed on a radial slide and a radial moving stage. An oil-proof baffle and an upper surface rolling cutter are fixed on the upper surface fixing component.

[0058] The upper surface fixing component fixes the position of the upper surface rolling cutter, so that the upper surface rolling cutter can roll the disc spring 9 after it moves. The oil-proof baffle protects against splashing oil generated during the rolling process, including flying debris generated during the rolling process. The top of the upper surface rolling cutter is a ball. During the rolling process on the upper surface of the disc spring 9, the rolling oil is output for lubrication through the rotation of the ball on the upper surface rolling cutter.

[0059] By setting the upper surface first drive assembly and the upper surface second drive assembly to move the position of the upper surface machining tool from the axial and radial directions, the upper surface rolling tool can be moved to the upper surface of the disc spring 9 to roll the upper surface of the disc spring 9.

[0060] The side machining mechanism includes a first side drive assembly, which has the same structure as the first upper surface drive assembly and is used for axial movement. The second side drive assembly has the same structure as the second upper surface drive assembly and is used for radial movement. A side machining tool is slidably disposed on the second side drive assembly. The side machining tool includes a side fixing member, which is fixed on the slide of the second side drive assembly. A side connecting member is fixed on the side fixing member, and a side rolling cutter is fixed on the side connecting member.

[0061] The side fixing component is fixed to the second side drive assembly, which facilitates the movement of the position. The side connector connects the side fixing component and the side rolling cutter. The top of the side rolling cutter is a ball. During the side rolling of the disc spring 9, the rolling oil is output for lubrication through the rotation of the ball on the side rolling cutter.

[0062] See Figure 1 and Figure 3 A feeding device for a butterfly spring includes a clamping mechanism 5, which includes a telescopic cylinder 51 and a servo motor 52. A drive module 53 is installed at the output end of the servo motor 52. The output end of the telescopic cylinder 51 is in contact with the upper surface of the drive module 53. A pair of clamping components 54 are installed below the drive module 53.

[0063] The telescopic cylinder 51 is fixed to the lower part of the transmission mechanism 2, and the upper part of the telescopic cylinder 51 is fixed to the fixed connecting plate 214. The output end of the servo motor 52 rotates, driving the drive module 53 to move. The servo motor 52 drives the double-rotating ball screw in the drive module 53 to rotate. The two nuts on the screw are fixed to the two clamping components 54 respectively. When the motor rotates, the two jaws move closer or further away synchronously.

[0064] The clamping assembly 54 includes a clamping rod 541, which is fixed to the drive module 53. Two connecting bolts 542 are provided on the clamping rod 541, and rotating clamping blocks 543 are rotatably mounted below each connecting bolt 542. The position of the rotating clamping blocks 543 can be adjusted according to the shape and size of the butterfly spring 9, facilitating clamping of the butterfly spring 9. After the rotating clamping blocks 543 are in contact with the outer edge of the butterfly spring 9, the telescopic cylinder 51 pushes the drive module 53 downwards, ensuring that the clamping force is evenly applied to the spring surface, avoiding clamping damage. The servo motor 52 precisely controls the clamping distance, ensuring accurate positioning of butterfly springs 9 of different specifications, providing reliable clamping assurance for subsequent rolling processing.

[0065] The disc spring 9 is fixed by the cooperation of the pressing assembly and the rotating assembly. The rotating assembly drives the pressing assembly to rotate, so that the pressing assembly applies a preload force to the disc spring 9 along the axial direction while clamping it. Then, the first driving assembly and the second driving assembly on the upper surface cooperate to drive the upper surface processing tool to perform roll forming on the upper surface of the disc spring 9. The first driving assembly and the second driving assembly on the side work together to drive the side rolling cutter to perform roll forming along the side wall of the disc spring 9. The upper surface and the side rolling are carried out simultaneously, which effectively improves the uniformity of the compressive stress distribution on the surface of the disc spring 9. It achieves the purpose of simultaneously performing roll forming on the upper surface and the side of the disc spring 9, and processing to the same precision with uniform rolling effect.

[0066] See Figure 2 The feeding mechanism 6 is fixed on the side wall of the support base. The feeding mechanism 6 includes a feeding electric cylinder 61. A slide groove 62 is provided on one side of the feeding electric cylinder 61. A slide table 63 is slidably provided on the slide groove 62. A fixing plate 64 is installed on the slide table 63. A material support platform 65 is provided on the fixing plate 64.

[0067] The feeding electric cylinder 61 drives the slide table 63 to move up and down. According to the position where the disc spring 9 needs to be clamped, the feeding electric cylinder 61 drives the slide table 63 to slide on the slide groove 62. When the slide table 63 moves, it simultaneously drives the fixed plate 64 and the support platform 65. The support platform 65 is triangular in shape. The shape of the support platform 65 can better support the disc spring 9. Through the triangular design of the support platform 65, when supporting the disc spring 9, it can provide a larger gripping position around the disc spring 9, which is convenient for clamping the workpiece.

[0068] See Figure 2 The material transfer mechanism 7 includes a material transfer connecting shaft 72, an upper fixed plate 78 mounted above the material transfer connecting shaft 72, a feeding plate 71 fixed below the upper fixed plate 78, a through hole in the middle of the feeding plate 71 that is adapted to the material transfer connecting shaft 72, a lower fixed plate 79 below the material transfer connecting shaft 72, a feeding plate 73 mounted on the lower fixed plate 79, a through hole in the middle of the feeding plate 73 that is adapted to the material transfer connecting shaft 72, a material placement groove 75 on the feeding plate 71, positioning grooves 76 with different spacings at the triangular positions around the material placement groove 75, the material transfer mechanism 7 also includes a positioning rod 77, the positioning rod 77 is fixed in different positioning grooves 76 according to the shape and size of the disc spring 9, and a feeding groove 74 on the feeding plate 73, the shape of the feeding groove 74 being adapted to the shape of the support platform 65.

[0069] The loading plate 71 provides an installation position and a setting position for the material placement groove 75 and the positioning groove 76. The positioning rod 77 is fixed in the positioning groove 76 according to the shape of the butterfly spring 9, and supports the butterfly spring 9. In the stopped state, the support platform 65 passes through the unloading groove 74 to reach the bottom, which can avoid interference caused by sudden start-up. A rotating shaft extends from the middle of the transfer connecting shaft 72. The rotation of the rotating shaft drives the loading plate 71 and the unloading plate 73 to rotate. After clamping the workpiece, it switches to the loading position with the workpiece and continues to load.

[0070] The support mechanism 8 includes a support base 81, on which a turntable 82 is mounted, and a drive assembly 83 is fixed on the side wall of the turntable 82.

[0071] The support base 81 provides bottom support, and the turntable 82 is inserted into the rotating shaft extending from the transfer connecting shaft 72. The drive assembly 83 includes a motor that drives the worm to rotate. The worm meshes with the worm wheel in the turntable 82. The central shaft of the worm wheel is fixed to the turntable surface to achieve low-speed, high-torque rotation. When the worm wheel central shaft rotates, it synchronously drives the transfer connecting shaft 72 to rotate.

[0072] The support base 81 drives the turntable 82 to rotate the material transfer connecting shaft 72 so that the workpiece position is aligned with the loading position. The loading electric cylinder 61 drives the slide table 63 to lift the support table 65 upward, lifting the butterfly spring 9 supported on the positioning rod 77 upward until it is lifted to the clamping position. The servo motor 52 drives the clamping assembly 54 to open, so that the butterfly spring 9 is between the two clamping assemblies 54. Then, the two clamping assemblies 54 are brought closer to each other to clamp the butterfly spring 9.

[0073] See Figure 4 The disc spring 9 includes an upper bearing surface 91, a side bearing surface 92, and a spring body 93. The upper surface processing mechanism 3 processes the side bearing surface 92, and the side processing mechanism processes the upper bearing surface 91. The upper surface rolling cutter 333 is in contact with the upper bearing surface 91, and the side rolling cutter is in contact with the side bearing surface 92. The rotating component rotates, and the upper surface rolling cutter and the side rolling cutter cooperate to roll the spring body 93.

[0074] See Figure 5 The feeding cylinder 61 drives the slide table 63 to move the support table 65 upward until the butterfly spring 9 on the transfer mechanism 7 is raised to the clamping position. The clamping assembly 54 adjusts the clamping width under the drive of the servo motor 52. The two rotating clamping blocks 543 clamp synchronously and clamp symmetrically along the center line to ensure stable gripping. The rotating clamping blocks 543 fit against the outer edge of the butterfly spring 9 until the clamping assembly 54 accurately clamps the butterfly spring 9, ensuring that the butterfly spring 9 and the clamping assembly 54 are in close contact and that no deviation occurs during the clamping process. This achieves the effect of accurately clamping the butterfly spring 9.

[0075] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
