Description

Technical Field

[0001] This utility model relates to the field of mechanical processing positioning technology, and in particular to a flipping mechanism with limit protection. Background Technology

[0002] Currently in the field of machining, the machining process is the core process of directly changing the shape, size and surface quality of a blank to make a part. It usually includes roughing, finishing, assembly, inspection and packaging. In this process, in order to ensure the machining accuracy of the parts and avoid dimensional deviations or surface quality defects caused by displacement during the machining process, clamping devices are needed to stably fix the parts. Therefore, the performance of the clamping device directly affects the overall machining efficiency and product quality.

[0003] Currently, there are various clamping devices for machining on the market. Among them, Chinese patent with announcement number "CN220240493U" discloses a representative machining clamping device. This device includes a machining table, with a clamping mechanism movably connected to the top of the machining table. A motor is fixedly connected to one side of the housing in the clamping mechanism. The output end of the motor is connected to a rotating shaft through a coupling. A positive and negative threaded rod is fixed to one end of the rotating shaft. A threaded block is movably connected to the outer wall of the positive and negative threaded rod. A connecting block is fixed to the top of the threaded block. The positive and negative threaded rod is driven to rotate by the motor, which drives the threaded block and the connecting block to move synchronously, thereby achieving rapid clamping of the workpiece. It can improve the clamping stability to a certain extent, avoid workpiece displacement during machining, and indirectly improve the machining effect. It has certain practicality in conventional machining scenarios.

[0004] However, a deeper analysis of the actual application scenarios of this patented device reveals significant defects and shortcomings, making it difficult to meet diverse processing needs. Firstly, after clamping and fixing the workpiece, the device cannot perform angle adjustment or flipping operations. From the perspective of debris removal, after the workpiece is processed, processing debris easily remains on the top of the fixture. Because the device cannot be flipped, these adhered debris are difficult to shake off quickly, and the remaining debris will interfere with the next workpiece processing, leading to a decrease in the positioning accuracy of the part during the next processing, thus affecting the product processing accuracy. From the perspective of processing flexibility, when different angles of the workpiece need to be processed, the device cannot adjust the workpiece posture by flipping. The operator must manually disassemble the workpiece and reposition it, which not only increases the operation steps and extends the processing time, but may also cause deviations due to secondary positioning, further affecting processing efficiency and quality. It is evident that the lack of angle adjustment and flipping functions in this device greatly limits its practical application. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] A flipping mechanism with limit protection includes a mounting base 1, support frames 2 are fixedly installed on both sides of the top of the mounting base 1, a main rotating mechanism 3 is fixedly installed between the inner sides of the top of the support frames 2, a clamping mechanism 5 is fixedly installed on one side of the rotating part inside the main rotating mechanism 3, and a jet cleaning mechanism 6 is fixedly installed in the middle of the side of the mounting base 1 near the clamping mechanism 5.

[0027] The main rotating mechanism 3 includes a fixed ring 31, which is fixedly installed on the upper end of the support frame 2. An annular groove 32 is formed on the inner side of the fixed ring 31, and a movable ring 33 is slidably connected inside the annular groove 32. A clamping mechanism 5 is fixedly installed on one side of the movable ring 33. A drive module 34 is fixedly installed on the side of the fixed ring 31 away from the jet cleaning mechanism 6. During application, the device first provides stable support for the overall structure through the mounting base 1. The support frames 2 on both sides of the top of the mounting base 1 provide a solid mounting foundation for the main rotating mechanism 3 at the top, ensuring that the main rotating mechanism 3 will not shake during operation and guaranteeing the stability of subsequent operations. When it is necessary to adjust the angle of the clamping mechanism 5 to adapt to processing requirements, the drive module 34 on the side of the fixed ring 31 away from the jet cleaning mechanism 6 in the main rotating mechanism 3 is activated. After the drive module 34 operates, it will drive the movable ring 33 in the annular groove 32 inside the fixed ring 31 to slide. Since the clamping mechanism 5 is fixed on one side of the movable ring 33, the movable ring 33... When sliding, the clamping mechanism 5 rotates synchronously, enabling flexible adjustment of the angle of the clamping mechanism 5. This eliminates the need for manual adjustment of the workpiece position, significantly improving processing flexibility and solving the problem of inconvenient angle adjustment in existing technologies. Furthermore, when the movable ring 33 slides within the annular groove 32, the annular groove 32 acts as a limit for the movable ring 33, preventing it from detaching from the fixed ring 31 and further ensuring the stability of the angle adjustment process. After the workpiece is processed, the air jet cleaning mechanism 6 located in the middle of the mounting base 1 near the clamping mechanism 5 is activated. The air jet cleaning mechanism 6 sprays airflow onto the clamping mechanism 5 and the workpiece surface to quickly remove residual debris from the processing, preventing debris from affecting the accuracy of the next processing step. This eliminates the need for manual cleaning, reducing operation steps and improving work efficiency. Throughout the process, the cooperation between the main rotating mechanism 3 and the air jet cleaning mechanism 6 not only meets the workpiece angle adjustment requirements but also achieves rapid cleaning of debris after processing, effectively compensating for the shortcomings of existing technologies in angle adjustment and debris cleaning.

[0028] Combination Figures 1-3 As shown, mounting holes 4 are provided at the four corners of the top of the mounting base 1. The mounting holes 4 are countersunk holes. The outer corners of the mounting base 1 are rounded. The drive module 34 includes a mounting arm 341 and a gear ring 342. The mounting arm 341 is fixedly mounted on the side of the upper end of a support frame 2 away from the clamping mechanism 5. The gear ring 342 is fixedly mounted on the side of the movable ring 33. A drive motor 343 is fixedly mounted on the outside of the mounting arm 341. A gear 344 is fixedly mounted through the mounting arm 341 at the output end of the drive motor 343. The gear 344 and the gear ring 342 are meshed. A protective shell 345 is fixedly mounted on the side of the fixed ring 31 away from the clamping mechanism 5. The protective shell 345 covers the outside of the gear ring 342 and the gear 344. A support rod 346 is fixedly mounted on the outside of the support frame 2. The overall cross-sectional shape of the annular groove 32 and the movable ring 33 is set as a convex shape.

[0029] In the above-described embodiments of this application, during the application of this device, it can be fixed to the processing area through the mounting holes 4 at the four corners of the top of the mounting base 1 during the installation stage. The mounting holes 4 are countersunk holes to prevent the head of the fixing bolt from protruding and to prevent the bolt from interfering with the normal operation of surrounding components. The outer edges of the mounting base 1 are rounded to prevent accidental collision and injury to the operator when approaching, thus improving operational safety. When it is necessary to drive the main rotating mechanism 3 to adjust the angle, the drive motor 343 on the outside of the mounting arm 341 in the drive module 34 is started. The output end of the drive motor 343 drives the gear 344 to rotate. Since the gear 344 is meshed with the toothed ring 342 on one side of the movable ring 33, the rotation of the gear 344 will drive the toothed ring 342 and the movable ring 33 to move synchronously, so that the movable ring 33 slides in the annular groove 32 inside the fixed ring 31. The annular groove 32 and the movable ring 33 are integrally cut off. The convex shape of the surface effectively restricts the sliding trajectory of the movable ring 33, preventing it from detaching from the annular groove 32 and ensuring stable transmission. Simultaneously, the protective outer shell 345 of the fixed ring 31, on the side away from the clamping mechanism 5, covers the outside of the gear ring 342 and gear 344, preventing machining debris from entering the meshing area of ​​the gear ring 342 and gear 344, thus avoiding damage to transmission accuracy and extending the service life of the transmission components. Furthermore, the support rod 346 on the outside of the support frame 2 enhances the overall structural strength of the support frame 2, preventing deformation due to stress during device operation. This further ensures the stable operation of the main rotating mechanism 3 and the clamping mechanism 5, ensuring accurate workpiece positioning during angle adjustment and preventing machining deviations caused by structural deformation. The entire process requires no manual intervention for transmission protection and structural stability, improving device reliability and reducing maintenance steps.

[0030] Example 2

[0031] Combination Figures 3-5As shown, the clamping mechanism 5 includes side arms 51, which are fixedly installed on both sides inside the movable ring 33. A shaft 52 is rotatably connected to the end of each side arm 51 away from the drive module 34. A placement plate 53 is fixedly installed on the inner side of the shaft 52. Limiting modules 55 are fixedly installed at both ends of the placement plate 53 near the fixed ring 31. A flip motor 54 is fixedly installed on the outer side of one side arm 51. The output end of the flip motor 54 is fixedly connected to the outer side of one shaft 52. The limiting module 55 includes a side frame 551, which is fixedly installed on the front side of the placement plate 53 near the fixed ring 31. At both ends, an electric push rod 552 is fixedly installed on the outer end of the side frame 551. A clamping frame 553 is fixedly installed on the output end of the electric push rod 552. An anti-drop clamping plate 554 is fixedly installed on the inner side of the clamping frame 553. A side seat 61 is fixedly installed on the side of the mounting base 1 near the clamping mechanism 5. A high-pressure air pump 62 is fixedly installed on the top of the side seat 61. A high-pressure jet pipe 63 is fixedly installed on the output end of the high-pressure air pump 62. A debris cleaning high-pressure blower pipe 64 is fixedly installed on the top of the high-pressure jet pipe 63 in a ring at equal intervals. The debris cleaning high-pressure blower pipe 64 is a metal air pipe that can be adjusted and bent at will.

[0032] In the above-described embodiments of this application, during the application of this device, the workpiece to be processed is first placed on the placement plate 53 of the clamping mechanism 5. Then, the limiting modules 55 at both ends of the placement plate 53 near the fixing ring 31 are activated. The electric push rod 552 at the outer end of the side frame 551 in the limiting module 55 pushes the clamping frame 553 towards the workpiece until the anti-drop clamping plate 554 on the inner side of the clamping frame 553 is in contact with the workpiece surface. The anti-drop clamping plate 554 can increase the contact area with the workpiece, preventing the workpiece from falling off during subsequent processing or angle adjustment, thus achieving stable limiting of the workpiece and ensuring that the workpiece will not be affected by displacement during processing. No manual assistance is required for fixing, reducing manpower input. When it is necessary to make local angle fine adjustments to the workpiece, the flip motor 54 on the outer side of the side arm 51 is activated. The output end of the flip motor 54 drives the shaft 52 to rotate, and the shaft 52 drives the placement plate 553 to rotate. 3. With synchronous rotation, the workpiece on the placement plate 53 is adjusted to the required angle to meet the angle requirements of different processing surfaces. There is no need to disassemble the workpiece for repositioning, which shortens the processing preparation time and improves the operating efficiency. After the workpiece is processed, the high-pressure air pump 62 on the side of the mounting base 1 near the clamping mechanism 5 is started. The high-pressure air pump 62 outputs high-pressure gas and delivers it to the high-pressure blower pipe 64 for debris cleaning through the high-pressure jet pipe 63. The high-pressure blower pipe 64 for debris cleaning is arranged in a ring and is a metal air pipe that can be adjusted and bent at will. The operator can adjust the bending angle of the blower pipe according to the position of the debris residue, so that the high-pressure airflow is accurately blown to the residual debris on the surface of the placement plate 53, the clamping frame 553 and the anti-drop clamping plate 554, quickly removing the debris and avoiding the debris from sticking and affecting the placement and positioning accuracy of the next workpiece. There is no need for manual wiping and cleaning, which further reduces the operation steps and ensures the continuous and stable operation of the device.

[0033] The working principle and advantages of this utility model are as follows: Before using this device, it can be stably fixed in the processing area by setting the mounting holes 4 at the four corners of the top of the mounting base 1. The mounting holes 4 are countersunk holes, which prevents the head of the fixing bolt from protruding during use, thereby preventing the bolt head from interfering with the normal operation of surrounding components. At the same time, the outer corners of the mounting base 1 are rounded, which prevents accidental collisions and injuries when the operator approaches the device. After installation, the connection status of each component should be checked to ensure the stability of subsequent operation. During use, after the device is fixed, the workpiece to be processed is placed on the placement plate 53, and the electric push rod 552 in the limit module 55 is activated. Since the side frame 551 is fixed at both ends of the placement plate 53 near the fixing ring 31, the side frame 551 provides a stable mounting base for the electric push rod 552 during use. After the electric push rod 552 is started, its output end will push the clamping frame 553 to move towards the workpiece until the anti-drop clamping plate 554 on the inner side of the clamping frame 553 is completely in contact with the workpiece surface. The anti-drop clamping plate 554 increases the contact area with the workpiece during use, thereby preventing the workpiece from falling off during subsequent flipping or processing, achieving stable limiting clamping of the workpiece, ensuring that the workpiece will not be affected by displacement during processing, and effectively solving the problem of easy displacement of the workpiece in the prior art.

[0034] After the workpiece is clamped, the angle can be adjusted according to processing requirements through the main rotating mechanism 3 and the flipping motor 54 of this device. The main rotating mechanism 3 and the flipping motor 54 rotate in opposite perpendicular directions, satisfying workpiece angle adjustment requirements from different dimensions. When overall flipping adjustment is required, the drive motor 343 in the drive module 34 is activated. The mounting arm 341 provides stable support for the drive motor 343 during use. After the drive motor 343 is activated, its output will drive the gear 344 to rotate. Because the gear 344 and... The gear ring 342 is engaged with the gear 344. Rotation of the gear 344 drives the gear ring 342 to rotate synchronously, which in turn causes the movable ring 33, fixed to the gear ring 342, to slide within the annular groove 32 inside the fixed ring 31. The annular groove 32 and the movable ring 33 have a convex cross-section. This shape prevents the movable ring 33 from disengaging from the annular groove 32 during use, ensuring stable sliding of the movable ring 33. The clamping mechanism 5 is fixedly connected to the movable ring 33, therefore the clamping mechanism 5 rotates synchronously with the movable ring 33, achieving overall angle adjustment of the workpiece along the direction of the main rotating mechanism 3. When further adjustment is needed... When making local fine adjustments to an angle, the flipping motor 54 on the outside of the side arm 51 can be started. At this time, the side arm 51 can provide rotational support for the shaft 52. After the flipping motor 54 is started, its output end will drive the shaft 52 to rotate. The shaft 52 is fixedly connected to the placement plate 53, thereby driving the placement plate 53 to rotate synchronously, realizing the local angle flipping of the workpiece along the direction of the flipping motor 54. This direction is perpendicular to the rotation direction of the main rotating mechanism 3, and the overall flipping can be further adjusted flexibly to adapt to different angle processing. The entire angle adjustment process does not require manual disassembly of the workpiece for repositioning, which reduces the operation steps and shortens the processing time during use, thereby avoiding secondary positioning deviation and solving the problem of poor processing flexibility in the prior art. At the same time, the protective shell 345 covers the outside of the toothed ring 342 and the gear 344. Its setting can prevent processing debris from entering the meshing area of ​​the toothed ring 342 and the gear 344 during use, avoiding affecting the transmission stability. The support rod 346 is fixed on the outside of the support frame 2. Its setting can enhance the structural strength of the support frame 2 during use and prevent the support frame 2 from deforming during the operation of the device.

[0035] After the workpiece is processed, the main rotating mechanism 3 drives the clamping mechanism 5 to flip so that the placement plate 53 and the workpiece face downwards. Then, the high-pressure air pump 62 in the jet cleaning mechanism 6 is started. The side seat 61 is fixed on the side of the mounting base 1 near the clamping mechanism 5. Its setting provides a stable mounting base for the high-pressure air pump 62 during use. After the high-pressure air pump 62 is started, its output end will output high-pressure gas. The high-pressure gas is delivered to the high-pressure blower pipe 64 for debris cleaning through the high-pressure jet pipe 63. Since the high-pressure blower pipe 64 for debris cleaning is arranged in a ring at the top of the high-pressure jet pipe 63 and can be bent at will, the operator can adjust the bending angle of the blower pipe according to the position of the debris residue during use. This allows the high-pressure airflow to be accurately blown onto the surface of the fixture and the workpiece. At this time, the workpiece and the fixture face downwards, and the debris can fall naturally downwards under the action of gravity. With the high-pressure airflow, the residual debris can be cleaned more quickly and thoroughly. This prevents the debris from interfering with the next processing during use, thereby ensuring the positioning accuracy of the next processing and solving the problem of difficult debris cleaning in the prior art.

[0036] In this technical solution, gear 344 and gear ring 342 are made of duplex stainless steel 2205, with a module range of 2-3mm, a tooth count range of 25-35, and a tooth tip circle diameter range of 54-108mm. This material, gear 344, exhibits strong corrosion resistance, strength, and weather resistance, and can be used for extended periods in air or water. The drive motor 343 is a DC servo motor, model 130ST-M06025, with a rated voltage range of 24-36V, a rated power range of 150-200W, and a rated speed range of 1500-2000r / min. The tilting motor 54 is a stepper motor. The part number is 57BYG250H, with a rated voltage range of 12-24V, a step angle range of 1.8°±5%, and a holding torque range of 1.2-1.8N·m; the high-pressure air pump 62 is a miniature high-pressure air pump 62, model HB-400H, with a rated voltage range of 220-240V, a rated power range of 300-400W, and a maximum air pressure range of 0.4-0.6MPa; the electric actuator 552 is a linear electric actuator 552, model XTL100, with a rated voltage range of 12-24V, a rated thrust range of 500-1000N, and a stroke range of 100-20... 0mm; the transmission parts of gear 344 use perfluoropolyether lubricant, model Fomblin Z03, which has good weather resistance and can lubricate for a long time in air and water; the controller is an embedded microcontroller, model STM32F407ZGT6, installed in the control box on one side of mounting base 1. The surface of the control box is equipped with a 7-inch TFT LCD screen with a resolution of 1024×600; the circuit system is powered by 220V AC mains power, which is converted to DC power by a 24V / 5A switching power adapter to power the various electronic components. The controller is connected to the drive motor 343 driver and the flip-flop driver through the GPIO interface. The rotary motor 54 driver, electric push rod 552 controller, and high-pressure air pump 62 relay control the motor speed and the extension / retraction speed of the electric push rod 552 via PWM signals, and control the start and stop of the high-pressure air pump 62 via relays. The control principle is that the controller receives the instructions input by the operator through the display screen, drives the action of each actuator, and simultaneously collects the signals from the motor encoder and angle sensor in real time to ensure the accuracy of the action, realizing the automated control of workpiece clamping, angle adjustment, and debris cleaning. At the same time, each motor is equipped with an encoder to facilitate real-time control of the rotation angle, and an angular displacement sensor can also be installed on the device to detect the angle rotation.

[0037] The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0038] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
