Description

Technical Field

[0001] The present invention belongs to the technical field of ring part flipping, and specifically relates to an automatic flipping mechanism for heavy-duty ring parts. Background Art

[0002] In the field of modern industrial manufacturing, ring parts are increasingly widely used, such as large engine ring components in the aerospace field, large generator stator rings in the energy industry, etc. These ring parts often need to be flipped during production, processing, inspection, and transportation; especially for large and heavy ring parts, their large size and heavy weight pose many difficulties and challenges during the flipping process.

[0003] In related technologies, ring parts usually use flipping mechanisms such as lifting slings and flipping devices to perform flipping operations on them. However, for large and heavy ring parts, the existing flipping mechanisms are difficult to bear such a large load or the part shapes with a large span of specification sizes. During the flipping process, the center of gravity position of the part changes complexly, and precise control and balance are required. Otherwise, it is extremely easy to cause the part to shake, tilt, or even fall, resulting in serious safety accidents. And during the flipping process of ring parts, manual assistance is required, which greatly increases the labor intensity of workers and poses safety hazards.

[0004] Therefore, there is an urgent need for an automatic flipping mechanism for heavy-duty ring parts to achieve the automatic in-situ flipping of large and heavy ring parts and improve the flipping stability and safety. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic flipping mechanism for heavy-duty ring parts to solve at least one of the problems and defects mentioned in the above background art.

[0006] Specifically, the present invention discloses an automatic flipping mechanism for heavy-duty ring parts, including:

[0007] A jacking mechanism, a rotary clamping mechanism, and a connecting mechanism;

[0008] The jacking mechanism includes a flipping table, and a jacking device is arranged through the middle of the flipping table, and the rotary clamping mechanism is arranged on the top of the jacking device;

[0009] The rotary clamping mechanism includes a clamping device, the clamping device is provided with a left clamping and flipping seat and a right clamping and flipping seat, and a synchronous flipping rod is arranged between the left clamping and flipping seat and the right clamping and flipping seat;

[0010] The rotary clamping mechanism further includes a driving device, and the driving device is provided with a clamping mechanism, a reduction gearbox, a rotating mechanism, and a flipping and clamping screw rod.

[0011] As a further solution of the present invention: The lifting mechanism further includes a lifting fixture mounting plate. The lifting device includes a lifting main shaft. A screw rod sliding device is provided at the top of the lifting main shaft, and the screw rod sliding device is arranged at the lower part of the lifting fixture mounting plate.

[0012] For this automatic flipping mechanism for heavy-duty ring parts, through the cooperation and lifting of the lifting main shaft of the lifting mechanism and the screw rod sliding device, the rotational motion of the screw rod sliding device is converted into the linear motion of the lifting main shaft, so that the top of the lifting mechanism holds the ring part and lifts the ring part to the space between the left clamping and flipping seat and the right clamping and flipping seat of the rotational clamping mechanism. Through the clamping motor of the driving device of the rotational clamping mechanism, the reduction gearbox is driven to drive the flipping clamping screw rod to rotate, so that the left clamping and flipping seat and the right clamping and flipping seat clamp the ring part; after the clamping is stable, the rotational motor is used to drive the synchronous flipping rod to rotate, and drive the left clamping and flipping seat and the right clamping and flipping seat to rotate in the same direction at the same time, so as to drive the ring part to achieve in-situ flipping; after the flipping is completed, the lifting main shaft continues to rise, and at the same time the clamping device releases the ring part, so that the ring part is again supported on the top of the lifting mechanism. At this time, the screw rod sliding device reverses, causing the lifting main shaft to fall along a straight line and driving the ring part back to its original position.

[0013] The automatic flipping mechanism for heavy-duty ring parts of the present invention can quickly and efficiently complete the in-situ flipping operation of ring parts without the intervention of operators. Compared with the traditional method of flipping heavy-duty ring parts, it greatly reduces the manual operation time and production safety accidents such as part damage and equipment damage that may be caused by improper manual operation, and shortens the flipping time of a single ring part, improving the overall production efficiency and safety; at the same time, through the cooperation of the various components of this mechanism, precise control is achieved, so that the flipping effect of each ring part is the same, thus ensuring the consistency between the parts in batch production and improving the production quality of the ring parts.

[0014] As a further solution of the present invention: The lifting device further includes a plurality of lifting auxiliary shafts, and the plurality of lifting auxiliary shafts are all arranged at the lower part of the lifting fixture mounting plate.

[0015] Since the lifting device further includes a plurality of lifting auxiliary shafts, and the plurality of lifting auxiliary shafts are all arranged at the lower part of the lifting fixture mounting plate, the stability of the lifting main shaft during the lifting and lowering process can be further improved through the plurality of lifting auxiliary shafts, ensuring that the lifting main shaft will not swing or shake during the process of lifting the ring part, and improving the output torque and control accuracy, guaranteeing the consistency and efficiency of the flipping of each ring part, realizing the in-situ flipping operation of larger and heavier ring parts, and improving the versatility and practicability of the mechanism.

[0016] As a further solution of the present invention: a jacking motor mounting plate is provided on the turning table, a jacking motor is provided at the bottom of the jacking motor mounting plate, a transmission shaft is provided at the top of the jacking motor mounting plate, and the transmission shaft is connected to the lead screw sliding device.

[0017] By providing a jacking motor mounting plate on the turning table, a jacking motor at the bottom of the jacking motor mounting plate, a transmission shaft at the top of the jacking motor mounting plate, and connecting the transmission shaft to the lead screw sliding device, the transmission shaft is driven to rotate by the jacking motor, so that the transmission shaft drives the lead screw sliding device to rotate, thereby converting the rotational motion of the lead screw sliding device into a linear motion of the jacking main shaft, realizing the jacking of the annular part at the top of the jacking mechanism, effectively and accurately controlling the rising height and speed of the jacking main shaft, making the annular part more smoothly and accurately jacked to the clamping surface between the left clamping turning seat and the right clamping turning seat, ensuring the stability and reliability of the jacking process.

[0018] As a further solution of the present invention: a position sensor is provided on one side of one of the jacking sub-shafts, and a signal generator is provided at the bottom of the jacking sub-shaft.

[0019] Since a position sensor is provided on one side of one of the jacking sub-shafts and a signal generator is provided at the bottom of the jacking sub-shaft, during the jacking process of the annular part, the position sensor can receive the position signal sent by the signal generator, and can accurately judge the real-time position of the jacking sub-shaft, avoiding the situation of over-jacking or not reaching the specified position, improving the accuracy and reliability of the operation, ensuring that the annular part can be accurately jacked to the preset height, providing a good basis for the subsequent clamping and turning operations, ensuring the smooth progress of the entire turning process, and when detecting an abnormal position, an alarm signal can be sent in time to prompt the operator that there may be a fault in the equipment, ensuring that timely intervention or adjustment can be made to ensure the safety of the operation process.

[0020] As a further solution of the present invention: a plurality of support plates are provided on the upper part of the jacking fixture mounting plate, and positioning pins are respectively provided at the tops of the plurality of support plates.

[0021] By providing a plurality of support plates on the upper part of the jacking fixture mounting plate and positioning pins at the tops of the plurality of support plates respectively, the positioning pins can effectively prevent the annular part from shifting during the turning process, avoiding collisions and interferences between the annular part and the equipment or other components, causing scratches and deformations on the surface of the part, ensuring the stability of the annular part during the turning process, and improving the qualified rate and quality of the product.

[0022] As a further solution of the present invention: The connecting mechanism includes a turning mechanism mounting plate, a turning mechanism bottom plate is arranged between the turning mechanism mounting plate and the rotary clamping mechanism, guide rails are respectively arranged on the upper and lower sides of the turning mechanism bottom plate, and the positioning pins at the tops of several support plates extend to both ends of the guide rails.

[0023] Since the connecting mechanism includes a turning mechanism mounting plate, a turning mechanism bottom plate is arranged between the turning mechanism mounting plate and the rotary clamping mechanism, guide rails are respectively arranged on the upper and lower sides of the turning mechanism bottom plate, and the positioning pins at the tops of several support plates extend to both ends of the guide rails. Through the upper and lower two guide rails on the turning mechanism bottom plate, the loads and frictions of the rotary left clamping turning seat and the right clamping turning seat during clamping and turning the annular part can be dispersed, so that the force on the rotary clamping mechanism during turning is more balanced, reducing the risk of damage caused by local overload, and effectively enhancing the stability of the turning mechanism; at the same time, the guide rails provide precise guidance for the clamping movement of the rotary clamping mechanism. When the rotary clamping mechanism performs a clamping action, the guide rails can ensure that the left clamping turning seat and the right clamping turning seat move along a predetermined trajectory, reducing the deviation during the movement process, and the positioning pins extend to both ends of the guide rails, further restricting the position of the rotary clamping mechanism and preventing it from shifting during the clamping process, thereby improving the clamping accuracy of the annular part.

[0024] As a further solution of the present invention: Clamping blocks are respectively arranged on the clamping surfaces of the left clamping turning seat and the right clamping turning seat.

[0025] By respectively arranging clamping blocks on the clamping surfaces of the left clamping turning seat and the right clamping turning seat, the clamping surfaces of the clamping blocks can be matched with the outer peripheral surfaces of annular parts of different specifications or shapes, so as to realize the turning of annular parts of different specifications or shapes. Moreover, the clamping surfaces of the clamping blocks form a line contact with the outer peripheral surfaces of the annular parts, which can increase the friction force and contact area between the clamping surfaces of the clamping blocks and the outer peripheral surfaces of the annular parts, effectively preventing the annular parts from sliding or shifting in the clamping blocks of the left clamping turning seat and the right clamping turning seat, ensuring the stable clamping force between the clamping blocks and the annular parts, improving the stability and reliability of the turning process of the annular parts, and can disperse the clamping stress on the outer peripheral surface of the annular parts, reducing the situation of excessive local pressure, reducing the risk of being scratched or deformed on the outer peripheral surface of the annular parts, and ensuring the integrity and surface quality of the annular parts.

[0026] As a further solution of the present invention: Elastic rubber pads are arranged on the clamping surfaces of the clamping blocks.

[0027] During the process of clamping the annular part, the clamping block is likely to cause scratches, indentations and other damages on the outer peripheral surface of the annular part. By setting an elastic rubber pad on the clamping surface of the clamping block, the clamping surface of the clamping block is in flexible contact with the outer peripheral surface of the annular part, preventing the clamping surface of the clamping block from damaging the outer peripheral surface of the annular part, ensuring the quality and service performance of the annular part, and at the same time being able to reduce the noise generated during the clamping of the annular part and improve the working comfort.

[0028] As a further solution of the present invention: the clamping block is arc-shaped or V-shaped.

[0029] Since the clamping block is arc-shaped or V-shaped, the clamping surface of the arc-shaped or V-shaped clamping block can further increase the contact area and friction force with the outer peripheral surface of the annular part. When the annular part is flipped, the larger contact area and friction force can effectively prevent the annular part from sliding or shifting in the clamping block, especially avoiding the flipping deviation, equipment damage and even safety accidents caused by the sliding of the part during the flipping of larger and heavier annular parts, and improving the stability and safety of the flipping of the annular part.

[0030] As a further solution of the present invention: telescopic brackets are respectively arranged at the bottoms of the support legs of the flipping table.

[0031] Since telescopic brackets are respectively arranged at the bottoms of the support legs of the flipping table, by adjusting the telescopic brackets, the flatness of the tabletop of the flipping table can be ensured, avoiding the influence of the unevenness of the tabletop of the flipping table on the lifting and flipping of the annular part, ensuring that the annular part is on a stable and horizontal flipping table for lifting and flipping operations, improving the flipping accuracy of the annular part and reducing the defective rate.

[0032] As a further solution of the present invention: fixing plates are respectively arranged on the two side cross beams at the bottom of the flipping table.

[0033] Since fixing plates are respectively arranged on the two side cross beams at the bottom of the flipping table, and the flipping table is connected to the ground or foundation through the fixing plates, when the lifting mechanism or the rotary clamping mechanism is operating, the flipping table can maintain a stable posture, avoiding the shaking or displacement of the flipping table caused by the vibration generated during the lifting or flipping of the annular part, and further improving the stability during the operation of the flipping mechanism.

[0034] As a further solution of the present invention: dust covers are respectively arranged on the upper surface and the lower surface of the flipping table.

[0035] By providing dust covers on the upper and lower surfaces of the turning table respectively, the lifting mechanism can be effectively wrapped, preventing the splashing of cutting fluid, grinding chips, etc. during the production process from causing wear to the components of the lifting mechanism, resulting in reduced accuracy, ensuring that the components of the lifting mechanism maintain a relatively clean operating environment, thereby guaranteeing the high-precision operation of the lifting mechanism and ensuring the machining quality of the product.

[0045] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the following further specifically describes the technical solutions of the present invention through embodiments and in conjunction with the accompanying drawings.

However, it is obvious that one or more embodiments may be implemented without these specific details. In other instances, well-known structures and devices are shown in diagrammatic form to simplify the drawings.

[0047] As Figure 1-6 shown in the embodiments of the present invention, an automatic flipping mechanism for heavy-duty annular parts includes: a lifting mechanism, a rotating clamping mechanism, and a connecting mechanism; the lifting mechanism includes a flipping table 1, and a lifting device 11 is disposed through the middle of the flipping table 1, and the rotating clamping mechanism is disposed on the top of the lifting device 11; the rotating clamping mechanism includes a clamping device 21, the clamping device 21 is provided with a left clamping flipping seat 211 and a right clamping flipping seat 212, and a synchronous flipping rod 213 is provided between the left clamping flipping seat 211 and the right clamping flipping seat 212; the rotating clamping mechanism further includes a driving device 22, and the driving device 22 is provided with a clamping motor 221, a reduction box 222, a rotating motor 223, and a flipping clamping lead screw 224.

[0048] The lifting mechanism further includes a lifting fixture mounting plate 12, the lifting device 11 includes a lifting main shaft 111, a lead screw sliding device 112 is disposed at the top of the lifting main shaft 111, and the lead screw sliding device 112 is disposed at the lower part of the lifting fixture mounting plate 12.

[0049] During use, for this automatic flipping mechanism for the heavy-duty annular part, through the cooperation of the lifting main shaft 111 of the lifting mechanism and the screw rod sliding device 112, the rotational motion of the screw rod sliding device 112 is converted into the linear motion of the lifting main shaft 111, so that the top of the lifting mechanism holds the annular part and lifts the annular part to between the left clamping and flipping seat 211 and the right clamping and flipping seat 212 of the rotary clamping mechanism. Through the clamping motor 221 of the driving device 22 of the rotary clamping mechanism, the driving reduction gearbox 222 drives the flipping and clamping screw rod 224 to rotate, so as to clamp the annular part by the left clamping and flipping seat 211 and the right clamping and flipping seat 212; after the clamping is stable, through the rotary motor 223, the synchronous flipping rod 213 is driven to rotate, and the left clamping and flipping seat 211 and the right clamping and flipping seat 212 are driven to rotate in the same direction at the same time, so as to drive the annular part to realize in-situ flipping; after the flipping is completed, the lifting main shaft 111 continues to rise, and at the same time the clamping device 21 releases the annular part, so that the annular part is supported on the top of the lifting mechanism again. At this time, the screw rod sliding device 224 reverses, so that the lifting main shaft 111 falls along a straight line and drives the annular part back to its original position.

[0050] Specifically, the automatic flipping mechanism for the heavy-duty annular part of the present invention can quickly and efficiently complete the in-situ flipping operation of the annular part without the intervention of an operator. Compared with the traditional method of flipping the heavy-duty annular part, the manual operation time is greatly reduced, and production safety accidents such as part damage and equipment damage caused by improper manual operation are reduced. At the same time, the flipping time of a single annular part is shortened, and the overall production efficiency and safety are improved; at the same time, through the cooperation of the components of the mechanism, precise control is realized, so that the flipping effect of each annular part is the same, thereby ensuring the consistency between the parts in batch production and improving the production quality of the annular parts.

[0051] As Figure 3 shown, the lifting device 11 further includes a plurality of lifting auxiliary shafts 113, and the plurality of lifting auxiliary shafts 113 are all arranged under the lifting fixture mounting plate 12.

[0052] Specifically, since the lifting device 11 further includes a plurality of lifting auxiliary shafts 113, and the plurality of lifting auxiliary shafts 113 are all arranged under the lifting fixture mounting plate 12, the stability of the lifting main shaft 111 during the lifting and lowering process can be further improved through the plurality of lifting auxiliary shafts 113, ensuring that the lifting main shaft 111 will not swing or shake during the process of lifting the annular part, and improving the output torque and control accuracy, ensuring the consistency and efficiency of the flipping of each annular part, realizing the in-situ flipping operation of larger and heavier annular parts, and improving the versatility and practicability of the mechanism.

[0053] As Figure 2 and Figure 3As shown in the figure, a jacking motor mounting plate 13 is provided on the turnover table 1. A jacking motor is provided at the bottom of the jacking motor mounting plate 13, and a transmission shaft 14 is provided at the top of the jacking motor mounting plate 13. The transmission shaft 14 is connected to the lead screw sliding device 112.

[0054] Specifically, by providing a jacking motor mounting plate 13 on the turnover table 1, a jacking motor is provided at the bottom of the jacking motor mounting plate 13, a transmission shaft 14 is provided at the top of the jacking motor mounting plate 13, and the transmission shaft 14 is connected to the lead screw sliding device 112. The transmission shaft 14 is driven by the jacking motor to rotate, so that the transmission shaft 14 drives the lead screw sliding device 112 to rotate, thereby converting the rotational motion of the lead screw sliding device 112 into the linear motion of the jacking main shaft 111, realizing the jacking of the annular part at the top of the jacking mechanism, effectively and accurately controlling the rising height and speed of the jacking main shaft 111, and making the annular part jack up to the clamping surface between the left clamping turnover seat 211 and the right clamping turnover seat 212 more smoothly and accurately, ensuring the stability and reliability of the jacking process.

[0055] Further, as Figure 3 shown, a position sensor 15 is provided on one side of one of the jacking sub-shafts 113, and a signal generator 16 is provided at the bottom of the jacking sub-shaft 113.

[0056] Specifically, since a position sensor 15 is provided on one side of one of the jacking sub-shafts 113 and a signal generator 16 is provided at the bottom of the jacking sub-shaft 113, during the jacking process of the annular part, the position sensor 15 can receive the position signal sent by the signal generator 16, and can accurately judge the real-time position of the jacking sub-shaft 113, avoiding the situation of over-jacking or not reaching the specified position, improving the accuracy and reliability of the operation, ensuring that the annular part can be accurately jacked up to the preset height, providing a good basis for the subsequent clamping and turnover operations, ensuring the smooth progress of the entire turnover process, and when an abnormal position is detected, an alarm signal can be sent in time to prompt the operator that there may be a fault in the equipment, ensuring that timely intervention or adjustment can be made to ensure the safety of the operation process.

[0057] As Figure 2 shown, a plurality of support plates 17 are provided on the upper part of the jacking fixture mounting plate 12, and positioning pins 18 are respectively provided at the tops of the plurality of support plates 17.

[0058] Specifically, by providing a plurality of support plates 17 on the upper part of the jacking fixture mounting plate 12 and positioning pins 18 are respectively provided at the tops of the plurality of support plates 17, the positioning pins 18 can effectively prevent the annular part from shifting during the turnover process, avoiding the annular part from colliding with or interfering with the equipment or other components, causing scratches, deformation, etc. on the surface of the part, ensuring the stability of the annular part during the turnover process, and improving the qualified rate and quality of the product.

[0059] Furthermore, as shown in Figure 1 and Figure 4 , the connecting mechanism includes a flipping mechanism mounting plate 31. A flipping mechanism bottom plate 32 is arranged between the flipping mechanism mounting plate 31 and the rotary clamping mechanism. Guide rails 33 are respectively arranged on the upper and lower sides of the flipping mechanism bottom plate 32. The positioning pins 18 at the tops of several support plates 17 extend to both ends of the guide rails 33.

[0060] Specifically, since the connecting mechanism includes a flipping mechanism mounting plate 31, a flipping mechanism bottom plate 32 is arranged between the flipping mechanism mounting plate 31 and the rotary clamping mechanism. Guide rails 33 are respectively arranged on the upper and lower sides of the flipping mechanism bottom plate 32. The positioning pins 18 at the tops of several support plates 17 extend to both ends of the guide rails 33. Through the upper and lower two guide rails 33 on the flipping mechanism bottom plate 32, the loads and frictions of the left clamping and flipping seat 211 and the right clamping and flipping seat 212 during clamping and flipping of the annular part can be dispersed, making the force on the rotary clamping mechanism more balanced during the flipping process, reducing the risk of damage caused by local overload, and effectively enhancing the stability of the flipping mechanism. At the same time, the guide rails 33 provide precise guidance for the clamping movement of the rotary clamping mechanism. When the rotary clamping mechanism performs a clamping action, the guide rails 33 can ensure that the left clamping and flipping seat 211 and the right clamping and flipping seat 212 move along a predetermined trajectory, reducing the deviation during the movement process. Moreover, the positioning pins 18 extend to both ends of the guide rails 33, further restricting the position of the rotary clamping mechanism and preventing it from shifting during the clamping process, thereby improving the clamping accuracy of the annular part.

[0061] According to an embodiment of the present invention, clamping blocks 214 are respectively arranged on the clamping surfaces of the left clamping and flipping seat 211 and the right clamping and flipping seat 212.

[0062] Specifically, by respectively arranging clamping blocks 214 on the clamping surfaces of the left clamping and flipping seat 211 and the right clamping and flipping seat 212, the clamping surfaces of the clamping blocks 214 can be matched with the outer peripheral surfaces of annular parts of different specifications or shapes, thereby realizing the flipping of annular parts of different specifications or shapes. And the clamping surfaces of the clamping blocks 214 form a line contact with the outer peripheral surfaces of the annular parts, which can increase the friction force and contact area between the clamping surfaces of the clamping blocks 214 and the outer peripheral surfaces of the annular parts, effectively preventing the annular parts from sliding or shifting in the clamping blocks 214 of the left clamping and flipping seat 211 and the right clamping and flipping seat 212, ensuring the stable clamping force between the clamping blocks 214 and the annular parts, improving the stability and reliability of the flipping process of the annular parts, and can disperse the clamping stress on the outer peripheral surface of the annular parts, reducing the situation of excessive local pressure, reducing the risk of being clamped and damaged or deformed on the outer peripheral surface of the annular part, and ensuring the integrity and surface quality of the annular part.

[0063] Furthermore, elastic rubber pads are arranged on the clamping surfaces of the clamping blocks 214.

[0064] Specifically, during the process of clamping the annular part, the clamping block 214 is likely to form scratches, indentations and other damages on the outer peripheral surface of the annular part. By providing an elastic rubber pad on the clamping surface of the clamping block 214, the clamping surface of the clamping block 214 is in flexible contact with the outer peripheral surface of the annular part, preventing the clamping surface of the clamping block 214 from damaging the outer peripheral surface of the annular part, ensuring the quality and service performance of the annular part, and at the same time being able to reduce the noise generated during the clamping of the annular part and improve the working comfort.

[0065] Further, the clamping block 214 is arc-shaped or V-shaped.

[0066] Specifically, since the clamping block 214 is arc-shaped or V-shaped, for the arc-shaped or V-shaped clamping block 214, its clamping surface can further increase the contact area and friction force with the outer peripheral surface of the annular part. During the flipping operation of the annular part, the larger contact area and friction force can effectively prevent the annular part from sliding or shifting in the clamping block, especially avoiding the flipping deviation, equipment damage and even safety accidents caused by the sliding of the part during the flipping of larger and heavier annular parts, improving the stability and safety of the flipping of the annular part.

[0067] Such as Figure 1 and Figure 2 As shown, telescopic brackets 19 are respectively provided at the bottom of the support legs of the flipping table 1.

[0068] Specifically, since telescopic brackets 19 are respectively provided at the bottom of the support legs of the flipping table 1, by adjusting the telescopic brackets 19, the flatness of the tabletop of the flipping table 1 can be ensured, avoiding the influence of the unevenness of the tabletop of the flipping table 1 on the lifting and flipping of the annular part, ensuring that the annular part is on a stable and horizontal flipping table for lifting and flipping operations, improving the flipping accuracy of the annular part and reducing the defective rate.

[0069] Further, fixing plates are respectively provided on the cross beams on both sides at the bottom of the flipping table 1.

[0070] Specifically, since fixing plates are respectively provided on the cross beams on both sides at the bottom of the flipping table 1, and the fixing plates are preferably L-shaped; the flipping table 1 is connected to the ground or foundation through the fixing plates, so that when the lifting mechanism or the rotary clamping mechanism is operating, the flipping table can maintain a stable posture, avoiding the shaking or displacement of the flipping table 1 caused by the vibration generated during the lifting or flipping of the annular part, and further improving the stability during the operation of this flipping mechanism.

[0071] Such as Figure 2 As shown, dust covers 34 are respectively provided on the upper surface and the lower surface of the flipping table 1.

[0072] Specifically, dust covers 34 are respectively arranged on the upper surface and the lower surface of the turnover table 1, which can effectively wrap the jacking mechanism, prevent the splashing of cutting fluid, grinding chips, etc. during the production process from causing wear to the components of the jacking mechanism, resulting in reduced precision, ensure that the components of the jacking mechanism maintain a relatively clean operating environment, thereby ensuring the high-precision operation of the jacking mechanism and the machining quality of the product.

[0073] In addition, the applicable range of this heavy-duty ring part automatic turnover mechanism is large. According to the reasonable setting of the clamping device 21, the clamping motor 221 and the jacking device 11, it can meet the automatic in-situ turnover of larger and heavier ring parts. In this embodiment, the preferred range is ring parts with a weight of 60 kg - 180 kg and an outer diameter of 140 mm - 300 mm.

[0074] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention.
