Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a flipping fixture for heavy cylindrical parts. Background Technology

[0002] For heavy machinery processing enterprises, large heavy-duty parts with extreme dimensions and large tonnage in heavy equipment manufacturing are difficult to flip when it is necessary to change the processing station. The currently widely used flipping method is to use overhead cranes and wire ropes to flip the parts. Although this method can adapt to multi-station flipping of various types and specifications of workpieces, it has the disadvantages of low efficiency and poor safety and reliability.

[0003] In the prior art, Chinese invention patent application CN102785119A discloses a multi-functional flipping device with a dual-winch forward and reverse drive flipping worktable, including an L-shaped rotary support table, a movable worktable, a flipping worktable, a roller support base, a main sprocket transmission system, a screw transmission system, a forward winch drive system, and a reverse winch drive system. This technical solution uses an L-shaped rotary support table to realize the workpiece flipping motion. The movement of the movable worktable and the flipping of the flipping worktable are coordinated to adapt to different types and specifications of workpieces and constrain the workpiece position, thereby realizing 90° / 180° two-station flipping of various types and specifications of heavy workpieces.

[0004] However, when adopting the above technical solutions, it is necessary to rely on the forward and reverse winch drive systems to cooperate with the screw drive to achieve workpiece flipping. This results in a large space occupied by the equipment and an increased number of parts, which not only increases the manufacturing cost, but also increases the maintenance difficulty and failure risk due to factors such as easy wear of the wire rope and high requirements for the synchronization accuracy of the drum. At the same time, the flipping process requires switching between forward / reverse winch and main sprocket drive multiple times. Under heavy working conditions, timing errors are easy to accumulate, which directly affects the stability and safety of the flipping process. Utility Model Content

[0005] To address the technical problems in the prior art, this utility model provides a flipping fixture for heavy-duty cylindrical parts, which is simple to operate and control, and provides a stable and reliable flipping solution for ultra-heavy cylinders.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a flipping fixture for heavy cylindrical parts, including a base, a rotating support platform rotatably disposed on the base, the rotating support platform rotating around its own axis, the rotating support platform including a support part one and a support part two, and a movable support seat, the movable support seat being movably disposed on the support part one, the rotating support seat being rotatably disposed on the movable support seat, the rotating support seat rotating around its own axis, the axial direction of the rotating support seat being perpendicular to the moving direction of the movable support seat.

[0007] This invention achieves a 180° flip of the workpiece by setting a rotating support base on a movable support base that can rotate around its own axis. After the rotating support table rotates 90°, the rotating support base is controlled to rotate 180°, and then the rotating support table is controlled to rotate 90° in the opposite direction. The flipping control logic is simple, which greatly simplifies the steps compared to the cumbersome operation of the existing technology when flipping the workpiece 180°. At the same time, during the rotation of the workpiece, there is always a supporting force in the direction of gravity, which can improve the stability and safety of the flipping.

[0008] Furthermore, the movable support is movably mounted on the support part one, and a drive cylinder is provided between the movable support and the support part one.

[0009] Furthermore, a rotary motor is provided on the movable support base. The rotary motor is a servo motor and is connected to a drive gear. The drive gear is rotatably mounted on the movable support base and meshes with an external gear ring. The external gear ring is coaxially arranged with the rotary support base.

[0010] This invention uses a rotary motor for driving, which can accurately control the rotation angle of the rotating support, preventing the workpiece from not turning into place and affecting the processing accuracy.

[0011] Furthermore, the rotating support base includes a support disk, which is rotatably mounted on the movable support base. The support disk is provided with a limiting member, which has a V-shaped cavity for placing the workpiece.

[0012] This invention uses a limiting component with a V-shaped cavity to effectively prevent the workpiece from rolling when the rotating support seat rotates, thereby further improving installation performance, stability, and accuracy.

[0013] Furthermore, the second support portion is characterized by having a buffer pad.

[0014] Furthermore, two drive chains are provided in the groove on the outer circumference of the rotating support platform, and two drive sprockets are rotatably and oppositely arranged on the base. The drive sprockets can mesh with the corresponding drive chains, and the two drive sprockets are connected to the same drive motor, which is mounted on the base.

[0015] This invention provides a symmetrical and balanced driving force to the rotating support platform by connecting the same drive motor, effectively avoiding the problems of uneven load and jamming that are prone to occur in single-chain drive, and greatly improving the stability and smoothness of the parts during the flipping process.

[0016] Furthermore, a support assembly is provided on the base, the support assembly including a support wheel, the axis of the support wheel being parallel to the axis of the rotating support platform, the support wheel being rotatably mounted on the base, and the outer circumferential surface of the support wheel rollingly rubbing against the outer circumferential surface of the rotating support platform.

[0017] This invention, through its support components, can effectively disperse the radial load applied by heavy workpieces, preventing deformation or transmission misalignment of the rotating support platform due to concentrated force, and can also significantly reduce frictional resistance during relative motion, thereby reducing energy loss and component wear.

[0018] Furthermore, the support assembly is provided with four support wheels arranged in two rows. Two support wheels that are opposite each other along the axial direction of the support wheels are connected by a support shaft, which is rotatably mounted on the base.

[0019] Furthermore, flanges are provided on both ends of the rotating support platform, and limit wheels are rotatably provided on the base and on the outer side of the corresponding flanges. The outer circumferential surface of the limit wheels can roll and rub against the corresponding flanges.

[0020] This invention achieves precise axial positioning of the rotating support platform by setting a limit switch, effectively preventing axial movement during the flipping process and ensuring the flipping and positioning accuracy of heavy cylindrical parts.

[0021] Furthermore, the limiting wheel is positioned between the two support wheels on the same side of the support assembly.

[0022] In this invention, the limiting wheel and the two corresponding support wheels form a three-point local constraint unit, which not only optimizes the structural layout on the base and reduces space occupation, but also, through the close cooperation between the support wheels and the limiting wheel, more accurately balances the radial load and axial movement trend of the rotating support table during the flipping process, further improving the overall stability and structural reliability of the heavy workpiece during the flipping process.

[0023] As can be seen from the above technical solutions, this utility model has the following advantages: This utility model provides a flipping fixture for heavy-duty cylindrical parts. By setting a rotating support base that can rotate around its own axis on a movable support base, after the rotating support table rotates 90°, the rotating support base is controlled to rotate 180°, and then the rotating support table is controlled to rotate 90° in the opposite direction, achieving a 180° flip of the workpiece. The flipping control logic is simple, greatly simplifying the steps compared to the cumbersome operation of existing technologies when flipping the workpiece 180°. Simultaneously, during the workpiece rotation, a supporting force is always present in the direction of gravity, improving the stability and safety of the flipping. Driven by a rotary motor, the rotation angle of the rotating support base can be accurately controlled, preventing the workpiece from not being flipped properly and affecting machining accuracy. By using a limiting component with a V-shaped cavity, the workpiece rolling is effectively prevented when the rotating support base rotates, further improving installation, stability, and accuracy. Connecting to the same drive motor can provide power to the rotating support table. The symmetrical and balanced driving force effectively avoids the problems of uneven load and jamming that are prone to occur in single-chain drives, greatly improving the stability and smoothness of the parts during the flipping process. The support components can effectively disperse the radial load applied by heavy workpieces, preventing deformation or transmission deviation of the rotating support table due to concentrated force, and can also significantly reduce frictional resistance in relative motion, reducing energy loss and component wear. By setting limiters, the rotating support table can be precisely axially limited, effectively preventing axial movement during the flipping process and ensuring the flipping positioning accuracy of heavy cylindrical parts. The limit wheel and the corresponding two support wheels form a three-point local constraint unit, which not only optimizes the structural layout on the base and reduces space occupation, but also, through the close cooperation between the support wheels and the limit wheels, more accurately balances the radial load and axial movement trend of the rotating support table during flipping, further improving the overall stability and structural reliability of the heavy workpiece during the flipping process.

[0033] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0034] like Figure 1 and Figure 2 As shown, this embodiment provides a flipping fixture for heavy cylindrical parts, including a base 1, a rotating support platform 10, a translational support base, and a rotating support base 23. The rotating support platform 10 is rotatably mounted on the base 1 and rotates around its own axis. The rotating support platform 10 includes a first support part 7 and a second support part 5, and also includes a movable support base 14. The movable support base 14 is movably mounted on the first support part 7, and the rotating support base 23 is rotatably mounted on the movable support base 14 and rotates around its own axis. The axial direction of the rotating support base 23 is perpendicular to the moving direction of the movable support base 14.

[0035] This embodiment, by setting a rotating support 23 that can rotate around its own axis on the movable support 14, allows the workpiece 6 to be flipped 180° after the rotating support table 10 rotates 90° and the movable support 14 moves horizontally to provide rotation space for the workpiece 6. After controlling the rotating support 23 to rotate 180°, the rotating support table 10 is then controlled to rotate 90° in the opposite direction. The flipping control logic is simple, greatly simplifying the steps compared to the cumbersome operation of the existing technology when flipping the workpiece 6 180°. At the same time, during the rotation of the workpiece 6, there is always a supporting force in its direction of gravity, which can improve the stability and safety of the flipping.

[0036] Workpiece 6 is a heavy cylindrical part, and the movable support 14 bears a large load. To ensure stable movement under load conditions, such as Figure 3 As shown, in this embodiment, the movable support base 14 has a plate-like structure. The movable support base 14 is movably mounted on the support part 7 by guide wheels that rotate at both ends. The support part 7 is provided with a sliding groove at a corresponding position. A drive cylinder 9 is provided between the movable support base 14 and the support part 7. The movement of the movable support base 14 is controlled by the extension and retraction of the drive cylinder 9 to meet the working conditions.

[0037] In order to precisely control the rotation angle of the rotary support 23, such as Figure 4 and Figure 7 As shown, in this embodiment, a rotary motor 24 is bolted onto the movable support base 14. The rotary motor 24 is a servo motor. The motor shaft of the rotary motor 24 is connected to a bevel gear reducer 18. The output shaft of the bevel gear reducer 18 is connected to a drive gear 25. The drive gear 25 is horizontally arranged and rotatably mounted on the movable support base 14 through corresponding shafts and bearings. The drive gear 25 meshes with an external gear ring 15, and the external gear ring 15 is coaxially arranged with the rotating support base 23. Furthermore, the rotating support 23 includes a support disk 12, with an external gear ring 15 sleeved on the outer circumference of the support disk 12. The support disk 12 is rotatably mounted on the movable support 14 via a slewing support bearing. A limiting member 11 is provided on the support disk 12, and the limiting member 11 is provided with a V-shaped cavity 16. The V-shaped cavity 16 is used to place the workpiece 6. By using the limiting member 11 with the V-shaped cavity 16, the workpiece 6 can be effectively prevented from rolling when the rotating support 23 rotates, further improving the installation performance, stability, and accuracy.

[0038] like Figure 2 As shown, in this embodiment, a buffer pad 13 is provided on the second support part 5. The buffer pad 13 is made of rubber, which can reduce the impact between the heavy workpiece 6 and the second support part 5 and improve the service life of the rotary support worktable.

[0039] To achieve stable rotation of the rotating support platform 10, such as Figure 1 and Figure 5 As shown, in this embodiment, two drive chains 8 are arranged in the groove on the outer circumferential surface of the rotating support platform 10. The drive chains 8 are three-row chains, which helps to improve the load-bearing capacity. Two drive sprockets 19 are rotatably and oppositely arranged on the base 1. The drive sprockets 19 are three-row sprockets, and the drive sprockets 19 can mesh with the corresponding drive chains 8. The two drive sprockets 19 are connected to the same drive motor 17, which is mounted on the base 1. Specifically, the motor shaft of the drive motor 17 is connected to the reduction gearbox 18 through a coupling. The reduction gearbox 18 is a dual-output shaft reduction gearbox 18, with two output shafts. The output shaft is connected to the corresponding drive sprocket 19 via corresponding couplings. The drive sprocket 19 is rotatably mounted on the base 1 via shafts and bearings. To enhance support and reduce the load on the drive sprocket 19, idler sprockets 20 are also provided on both sides of the drive sprocket 19. The idler sprockets 20 are rotatably supported on the base 1 via corresponding shafts and are also engaged with the corresponding drive chain 8. By connecting to the same drive motor 17, symmetrical and balanced driving force can be provided to the rotating support platform 10, effectively avoiding the problems of uneven load and jamming that are prone to occur in single-chain drive, and greatly improving the stability and smoothness of the parts during the flipping process.

[0040] To enhance the supporting effect on the rotating support platform 10, such as Figure 1 and Figure 6 As shown, in this embodiment, a support assembly 22 is provided on the base 1. The support assembly 22 includes a support wheel 2. The axial direction of the support wheel 2 is parallel to the axial direction of the rotating support platform 10. The support wheel 2 is rotatably mounted on the base 1, and the outer circumferential surface of the support wheel 2 rolls and rubs against the outer circumferential surface of the rotating support platform 10. Furthermore, in this embodiment, two support assemblies 22 are provided, each with four support wheels 2 arranged in a two-row layout. Two support wheels 2 that are axially opposite each other along the support wheel 2 are connected by a support shaft 21. The support shaft 21 is rotatably mounted on the base 1 via a bearing. Through the support assembly 22, the radial load applied by the heavy workpiece 6 can be effectively distributed, preventing the rotating support platform 10 from deforming or shifting due to concentrated force. It can also significantly reduce frictional resistance during relative motion, reducing energy loss and component wear.

[0041] To prevent axial movement of the rotating support platform 10, in this embodiment, such as Figure 1 and Figure 6As shown, flanges 26 are provided on both ends of the rotating support platform 10. Limiting wheels 3 are rotatably provided on the base 1, located outside the corresponding flanges 26. The outer circumferential surface of the limiting wheels 3 can roll and rub against the corresponding flanges 26. Specifically, a mounting seat 4 is provided on the base 1, and the mounting seat 4 mounts the limiting wheels 3 via corresponding shafts and bearings. By setting the limiting wheels, precise axial positioning of the rotating support platform 10 can be achieved, effectively preventing axial movement during its rotation and ensuring the rotational positioning accuracy of heavy cylindrical parts. To reduce the space required for the base 1... The corresponding limiting wheel 3 is arranged between the two support wheels 2 on the same side of the support component 22. In the embodiment, the mounting base 4 and the limiting wheel 3 are each provided with four. After this arrangement, the limiting wheel 3 and the two support wheels 2 on the same side form a three-point local constraint unit, which not only optimizes the structural layout on the base 1 and reduces space occupation, but also, through the close cooperation between the support wheel 2 and the limiting wheel 3, more accurately balances the radial load and axial movement trend of the rotating support table 10 during the flipping process, further improving the overall stability and structural reliability of the heavy workpiece 6 during the flipping process.

[0042] The flipping process of this heavy-duty cylindrical component flipping fixture is as follows: Initially, workpiece 6 is in a vertical position, with the limiting member 11 located on one side and in the middle of workpiece 6. One end of workpiece 6 rests on the buffer pad 13 of the support part 2 5. When workpiece 6 needs to be rotated 180°, firstly, the drive motor 17 controls the rotating support table 10 to rotate 90°. At this time, workpiece 6 rotates from a vertical position to a horizontal position. Workpiece 6 is supported on the limiting member 11. The movable support seat 14 drives workpiece 6 to move a set distance away from the support part 2 5 to avoid interference between workpiece 6 and the support part 2 5 when rotating. Then, the rotary motor drives the rotating support seat 23 to rotate 180°, the movable support seat 14 moves in the opposite direction to return to its original position, and the rotating support table 10 rotates in the opposite direction by 90°. Workpiece 6 is gradually erected, and its other end rests on the buffer pad 13 of the support part 2 5, completing the rotation of workpiece 6.

[0043] As can be seen from the above specific embodiments, this utility model has the following beneficial effects: 1. By setting a rotating support 23 that can rotate around its own axis on the movable support 14, after the rotating support table 10 rotates 90°, the rotating support 23 is controlled to rotate 180°, and then the rotating support table 10 is controlled to rotate 90° in the opposite direction, so that the workpiece 6 can be flipped 180°. The flipping control logic is simple, which greatly simplifies the steps compared with the cumbersome operation of the existing technology when flipping the workpiece 6 180°. At the same time, during the rotation of the workpiece 6, there is always a supporting force in its direction of gravity, which can improve the stability and safety of the flipping. 2. Driven by the rotary motor 24, the rotation angle of the rotary support 23 can be accurately controlled, preventing the workpiece 6 from not turning into place and affecting the processing accuracy; 3. By using the limiting member 11 with V-shaped cavity 16, the workpiece 6 can be effectively prevented from rolling when the rotating support 23 rotates, further improving the installation performance, stability and accuracy; 4. By connecting the same drive motor 17, a symmetrical and balanced driving force can be provided to the rotating support platform 10, which effectively avoids the problems of uneven load and jamming that are prone to occur in single chain drive, and greatly improves the stability and smoothness of the parts flipping process. 5. The support component 22 can effectively disperse the radial load applied by the heavy workpiece 6, avoid deformation or transmission deviation of the rotating support table 10 due to force concentration, and significantly reduce the frictional resistance in relative motion, thereby reducing energy loss and component wear. 6. By setting limiters, the rotating support platform 10 can be precisely axially limited, effectively preventing axial movement during the flipping process and ensuring the flipping and positioning accuracy of heavy cylindrical parts. The limiting wheel 3 and the corresponding two support wheels 2 form a three-point local constraint unit, which not only optimizes the structural layout on the base 1 and reduces space occupation, but also, through the close cooperation between the support wheels 2 and the limiting wheel 3, more accurately balances the radial load and axial movement trend of the rotating support table 10 during the flipping process, further improving the overall stability and structural reliability of the heavy workpiece 6 during the flipping process.
