Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing, and in particular to a flange turning and grinding system and a flange processing method. Background Art

[0002] In the fields of industrial pipelines, equipment connection, etc., flanges play a vital role as a part that connects pipelines, equipment or mechanical parts. Flanges, also known as flanges or flanges, are usually a disc-shaped metal body with holes around the periphery. They connect two planes with bolts and are sealed with gaskets in the middle. They can withstand greater pressure. However, during the processing of flanges, especially in the process of grinding planes and fine grinding inner circles, due to the inconsistent direction of parts when processing equipment and inner circle equipment, the flange needs to be flipped to complete the processing of different surfaces.

[0003] The processing method of flipping the flange also exists in the processing of compressor flanges. In the grinding process of traditional compressor flanges, the flipping operation relies on an automated robot, but such operation is cumbersome, which not only affects production efficiency, but also increases the failure rate of automated operation. In addition, the flange used in the compressor has a raised shaft at the axis, which can easily cause the flange to tip over during the flipping and grinding process, making it impossible to perform effective grinding.

[0004] Therefore, it is necessary to improve the existing flipping and grinding method of the compressor flange to overcome the defects of the prior art. Summary of the invention

[0005] In order to overcome the problems existing in the related art, one of the objects of the present invention is to provide a flange flipping and grinding system, which can grind the flange through different grinding devices, and during the grinding process, the flange is flipped by a flipping mechanism, which not only ensures that the different surfaces of the flange can be fully polished, but also avoids the defects of flipping the flange by a robot, thereby improving production efficiency.

[0006] A flange flip grinding system comprises a frame, a first conveying device and a second conveying device are arranged on the frame, one end of the first conveying device is connected to the second conveying device, and a flip mechanism is arranged between the first conveying device and the second conveying device; the flip mechanism comprises a rotating member, and a plurality of clamping positions for clamping flanges are arranged on the rotating member;

[0007] A first grinding mechanism is disposed above the first conveying device, and a second grinding mechanism is disposed above the second conveying device.

[0008] In this system, the core component of the flip mechanism is a rotating part that can rotate around its own axis. The rotating part is provided with multiple snap-in positions, which are specifically used to firmly snap-in the flange to ensure that the flange will not fall off or shift during the flipping process. In actual applications, the multiple snap-in positions on the flip mechanism can be adjusted according to different flanges, so that the system can easily adapt to the grinding needs of flanges of different specifications and sizes, improving the flexibility and scope of application of the system, and providing strong support for enterprises to cope with changing market demands.

[0009] In actual applications, the first grinding mechanism and the second grinding mechanism are used to grind different positions of the flange respectively. For example, the first grinding mechanism is used to grind the plane of the flange, and the second grinding mechanism can be used to grind the inner circle of the flange. In actual operation, the flange to be polished is first placed on the first conveying device, which is conveyed by the first conveying device. When the flange passes through the first grinding mechanism, the surface of the flange is polished by the first grinding mechanism. After the first grinding mechanism is finished, the flange continues to be conveyed by the first conveying device. The first conveying device sends the flange into the clamping position of the flipping mechanism. The clamping position rotates under the drive of the rotating member, thereby flipping the flange 180 degrees and allowing the flange to enter the second conveying device. The second conveying device transports the flange to the bottom of the second grinding mechanism for grinding at other positions, and sends it out after the grinding is completed. Through the use of the flipping mechanism, the system enables all surfaces of the flange to be fully polished, avoiding the problem of uneven grinding caused by the inconvenience of flange flipping in the traditional grinding method, thereby significantly improving the grinding quality and product consistency. Moreover, the use of the flipping mechanism avoids the use of a manipulator for complex and time-consuming flipping operations, making the entire grinding process smoother and more efficient. This not only shortens the production cycle, but also greatly improves the overall production capacity of the production line. In addition, the system can realize automatic grinding, reduce manual participation, reduce the labor intensity of workers, and also reduce the defective rate caused by improper manual operation, thereby reducing production costs.

[0010] In a preferred technical solution of the present invention, the rotating member includes a connecting rod and a dial, the connecting rod is arranged on the frame along the width direction of the frame, and the connecting rod is rotatably connected to the frame;

[0011] Two dials are provided, and the two dials are respectively fixed at opposite ends of the connecting rod; a plurality of levers are provided on the edge of each dial, and the plurality of levers are evenly distributed on the dial along the circumference of the dial, and a snap-fit ​​position is formed between two adjacent levers, and the snap-fit ​​positions on the two dials correspond to each other.

[0012] In this embodiment, the connecting rod is firmly arranged on the frame along the width direction of the frame, and is rotatably connected to the frame through bearings or other rotating connecting parts, ensuring that the connecting rod can rotate freely around its own axis. Two dials are provided, which are respectively fixed at both ends of the connecting rod to form a symmetrical layout. This design can enhance the stability of the rotating part, so that the clamping positions on the two dials can clamp the flange at the same time, ensuring the stability of the flange flipping. Multiple levers are designed on the edge of each dial, and these levers are evenly distributed along the circumference of the dial, and a clamping position for clamping the flange is naturally formed between two adjacent levers. The clamping positions on the two dials correspond to each other, ensuring that the flange can maintain a stable position during the flipping process and will not fall off due to bumps or vibrations.

[0013] In the actual working process, when the first conveying device conveys the flange to be polished to the flipping mechanism, the flange will be accurately inserted into the corresponding snap-in positions of the two dials. Subsequently, the connecting rod is driven to rotate by the driving device (such as a motor, a reducer, etc.), thereby driving the two dials to rotate synchronously to realize the flipping of the flange. After the flipping is completed, the flange will be smoothly taken away by the second conveying device and sent to the next process for polishing or processing.

[0014] The double dial design with evenly distributed levers allows the flange to always maintain a stable position during the flipping process, avoiding the flange falling off or damage caused by unstable flipping, and improving the stability and reliability of flipping.

[0015] In a preferred technical solution of the present invention, each of the shifting rods is provided with a plurality of pulleys, the pulleys are rotationally connected to the shifting rod, and the plurality of pulleys are arranged on the shifting rod along the length direction of the shifting rod.

[0016] The pulleys are mounted on the lever in a rotating connection. The pulleys are arranged in an orderly manner along the length of the lever, forming a series of efficient rolling support systems. The design of the pulleys greatly reduces the direct contact friction between the flange and the lever during the flipping process. Since the pulleys can rotate freely, when the flange and the pulleys come into contact and generate relative motion, the pulleys will roll with them, thus converting sliding friction into rolling friction. This conversion not only significantly reduces frictional resistance, but also greatly reduces the heat and wear generated by friction, extending the service life of the flip mechanism.

[0017] In addition, during the use process, the pulley enables the flange to slide onto the lever synchronously, and then the flange is flipped after the dial is turned. The distribution of multiple pulleys along the length of the lever provides a more uniform and stable support for the flange. During the flipping process, even if the flange is subjected to uneven external forces, the pulley can maintain the balance of the flange through its own rolling adjustment, thereby ensuring a smooth flipping process.

[0018] In a preferred technical solution of the present invention, a double-wheel guide rod is provided on the frame, both ends of the double-wheel guide rod are respectively exposed outside the frame, and the connecting rod is connected to the double-wheel guide rod through a first transmission belt.

[0019] The connecting rod is connected to the double-wheel guide rod through a first transmission belt. As a common transmission device, the transmission belt has multiple functions such as power transmission, noise reduction, and shock absorption. In the present application, it can smoothly transmit the power of the driving device to the connecting rod, thereby driving the dial and the flange to flip.

[0020] In a preferred technical solution of the present invention, the first grinding mechanism includes a grinding drive mechanism, a screw rod, a sliding sleeve and a grinding plate, the screw rod is rotatably arranged on the frame, and the screw rod spans above the first conveying device;

[0021] The grinding drive mechanism is fixed on the frame, and the output end of the grinding drive mechanism is fixedly connected to the screw rod; the sliding sleeve is arranged on the screw rod, the sliding sleeve is threadedly connected to the screw rod, and the grinding plate is arranged at the bottom of the sliding sleeve.

[0022] In actual use, the screw drives the sleeve and the grinding plate below to perform precise grinding operations by rotating. The sleeve and the screw are tightly connected by threads, and can move along its axial direction as the screw rotates, thereby driving the grinding plate to adjust its position. The grinding plate is the main working part for performing grinding tasks, and its surface is usually covered with wear-resistant materials to enhance the grinding effect.

[0023] The working process of the first grinding mechanism is as follows: when the grinding drive mechanism is started, its output end drives the screw to start rotating. Since the sleeve and the screw are connected by threads, the sleeve moves along the axial direction of the screw as the screw rotates. The movement of the sleeve drives the grinding plate to adjust its position, so that the grinding plate can contact different positions of the flange and grind the flange on the first conveying device.

[0024] In a preferred technical solution of the present invention, a first pulley is provided at one end of the screw rod, the first pulley is exposed outside the frame, and the first pulley is connected to the double-wheel guide rod through a second transmission belt.

[0025] In actual application, the grinding drive mechanism drives the screw to rotate, the screw drives the first pulley to rotate, thereby driving the double-wheel guide rod to rotate through the second transmission belt, and the rotation of the double-wheel guide rod can drive the connecting rod to rotate through the first transmission belt.

[0026] In a preferred technical solution of the present invention, the second conveying device comprises a first bracket, a conveying belt, a roller and a connecting rod, the first bracket is arranged on the frame, two first brackets are arranged, each of the first brackets is provided with a connecting rod, the connecting rod is rotatably matched with the first bracket, the roller is fixed on the connecting rod, and the conveying belt is arranged on the roller;

[0027] The frame is also provided with a second driving device, and an output end of the second driving device is fixedly connected to the connecting rod.

[0028] The roller is firmly fixed on the connecting rod and rotates with the rotation of the connecting rod. The conveyor belt is tightly wound on the roller. When the roller rotates, the conveyor belt moves with it, thereby realizing the conveyance of the workpiece. When the second drive device is started, its output end will drive the connecting rod to rotate, thereby driving the roller and the conveyor belt to start moving. The workpiece (flange) is placed on the conveyor belt and is transported to the designated processing position as the conveyor belt moves. The second drive device drives the connecting rod and roller to rotate, thereby driving the conveyor belt to move, realizing rapid and continuous conveying of the workpiece, greatly improving production efficiency.

[0029] In a preferred technical solution of the present invention, the second grinding mechanism includes a second bracket, and the second bracket spans above the second conveying device;

[0030] The second bracket is provided with a grinding disc, and the grinding disc is pivotally connected to the second bracket; the grinding disc is provided with a first bevel gear; the second bracket is also provided with a transmission shaft, and the transmission shaft is pivotally connected to the second bracket; a second bevel gear is provided at one end of the transmission shaft, and the second bevel gear is meshed with the first bevel gear;

[0031] A second pulley is also provided at one end of the connecting rod, and the transmission shaft is connected to the second pulley via a third transmission belt.

[0032] The transmission shaft is pivotally connected to the second bracket and is provided with a second bevel gear meshing with the first bevel gear. When the transmission shaft rotates, the grinding disc is driven to rotate synchronously through the meshing action of the bevel gears. The third transmission belt is connected between the transmission shaft and the second pulley, and is used to transmit the rotational power of the connecting rod (i.e., the driving part of the second conveying device) to the transmission shaft, thereby driving the grinding disc to rotate. When the second conveying device is started, the connecting rod drives the roller and the conveying belt to rotate to achieve continuous conveying of the workpiece. At the same time, the second pulley on the connecting rod transmits power to the transmission shaft through the third transmission belt. When the transmission shaft rotates, the second bevel gear on it meshes with the first bevel gear on the grinding disc, driving the grinding disc to rotate around the pivot. When the workpiece moves on the conveying belt, it passes under the grinding disc and is polished by the working surface of the grinding disc.

[0033] In a preferred technical solution of the present invention, a lifting mechanism is further provided on the frame, and the lifting mechanism is provided below the second grinding mechanism;

[0034] The lifting mechanism comprises two push rods hinged to each other, the middle parts of the two push rods are hinged to each other; the bottom of any one of the push rods is hinged to the frame, and the other push rod is slidably matched with the frame through a slide cylinder; a telescopic rod is provided on the frame, and the output end of the telescopic rod is fixedly connected to the slide cylinder;

[0035] A push plate is provided on the top of the two push rods, and the push rods are hinged to each other;

[0036] The lifting mechanisms are provided with two, and the push rods of the two lifting structures are respectively located on both sides of the conveyor belt.

[0037] The second grinding mechanism is arranged above the second conveying device, and is used for grinding the workpieces passing on the conveying belt.

[0038] Two mutually hinged push rods form a scissors-like structure. This design enables the push rod to achieve telescopic movement in the vertical direction. A telescopic rod (which can be a cylinder, hydraulic cylinder, etc.) is installed on the frame, and its output end is fixedly connected to the slide. The telescopic movement of the telescopic rod can drive the slide to move, and the movement of the slide drives the bottom of one of the push rods to move, thereby achieving the function of changing the position of the top of the push rod, that is, making the push rod rise and fall. The equipment is equipped with a lifting mechanism on both sides of the conveyor belt. In this way, the two lifting mechanisms can work synchronously to ensure that the workpiece (flange) remains horizontal during the lifting process.

[0039] During operation, when the telescopic rod is extended, it pushes the slide tube to move, so the push rod connected to the slide tube also moves. Since the two push rods are hinged in the middle, they will form an upward thrust to lift the push plate, and the push rod will lift the flange on the conveyor belt. Conversely, when the telescopic rod is retracted, the top of the push rod will move downward, and the push plate and the workpiece will also drop.

[0040] By controlling the extension amount of the telescopic rod, the height position of the workpiece can be accurately adjusted so that the workpiece (flange) can be connected to the second grinding mechanism to achieve the grinding of the flange.

[0041] A second object of the present invention is to provide a flange processing method, which is implemented based on a flange flipping and grinding system as described above.

[0042] This processing method uses the above-mentioned system to perform automatic grinding after the flange is formed, which can improve the processing efficiency of the flange, reduce production costs, and ensure the processing quality of the flange.

[0043] The beneficial effects of the present invention are:

[0044] The present invention provides a flange flipping and grinding system, which includes a frame, a first conveying device and a second conveying device are arranged on the frame, one end of the first conveying device is connected to the second conveying device, and a flipping mechanism is arranged between the first conveying device and the second conveying device; the flipping mechanism includes a rotating member, and a plurality of clamping positions for clamping the flange are arranged on the rotating member. A first grinding mechanism is arranged above the first conveying device, and a second grinding mechanism is arranged above the second conveying device. In actual application, the first grinding mechanism and the second grinding mechanism are respectively used to grind different positions of the flange, for example, the first grinding mechanism is used to grind the plane of the flange, and the second grinding mechanism can be used to grind the inner circle of the flange. In actual operation, the flange to be polished is first placed on the first conveying device, and the first conveying device conveys it. When the flange passes through the first grinding mechanism, the surface of the flange is polished by the first grinding mechanism. After the first grinding mechanism is polished, the flange continues to be conveyed by the first conveying device, and the first conveying device sends the flange into the clamping position of the flipping mechanism. The clamping position rotates under the drive of the rotating member, thereby flipping the flange 180 degrees, so that the flange enters the second conveying device. The second conveying device conveys the flange to the bottom of the second grinding mechanism for grinding at other locations, and sends it out after grinding is completed. Through the use of the flipping mechanism, the system allows all surfaces of the flange to be fully polished, avoiding the problem of uneven grinding caused by the inconvenience of flange flipping in the traditional grinding method, thereby significantly improving the grinding quality and product consistency. In addition, the use of the flipping mechanism avoids the use of a manipulator for complex and time-consuming flipping operations, making the entire grinding process smoother and more efficient. This not only shortens the production cycle, but also greatly improves the overall production capacity of the production line. In addition, the system can realize automated grinding, reduce manual participation, reduce the labor intensity of workers, and also reduce the defective rate caused by improper manual operation, thereby reducing production costs.

[0045] The present application also provides a flange processing method implemented based on the above-mentioned grinding system. The processing method uses the above-mentioned system to perform automatic grinding after the flange is formed, which can improve the processing efficiency of the flange, reduce production costs, and ensure the processing quality of the flange.

DETAILED DESCRIPTION

[0055] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0056] In the fields of industrial pipelines, equipment connection, etc., flanges play a vital role as a part that connects pipelines, equipment or mechanical parts. Flanges, also known as flanges or flanges, are usually a disc-shaped metal body with holes around the periphery. They connect two planes with bolts and are sealed with gaskets in the middle. They can withstand greater pressure. However, during the processing of flanges, especially in the process of grinding planes and fine grinding inner circles, due to the inconsistent direction of parts when processing equipment and inner circle equipment, the flange needs to be flipped to complete the processing of different surfaces.

[0057] The processing method of flipping the flange also exists in the processing of compressor flanges. In the grinding process of traditional compressor flanges, the flipping operation relies on an automated robot, but such operation is cumbersome, which not only affects production efficiency, but also increases the failure rate of automated operation. In addition, the flange used in the compressor has a raised shaft at the axis, which can easily cause the flange to tip over during the flipping and grinding process, making it impossible to perform effective grinding.

[0058] Based on this, the present application provides a flange flip grinding system.

[0059] Example 1

[0060] like Figure 1-Figure 7 As shown, a flange flip grinding system provided in this embodiment includes a frame 1, on which a first conveying device 100 and a second conveying device 210200 are arranged, one end of the first conveying device 100 is connected to the second conveying device 210200, and a flip mechanism 3 is arranged between the first conveying device 100 and the second conveying device 210200; the flip mechanism 3 includes a rotating member 31, on which a plurality of clamping positions 314313 for clamping flanges are arranged;

[0061] A first grinding mechanism 2 is disposed above the first conveying device 100 , and a second grinding mechanism 4 is disposed above the second conveying device 210200 .

[0062] In the system, the core component of the flip mechanism 3 is a rotating member 31, which can rotate around its own axis. The rotating member 31 is provided with multiple clamping positions 314313, which are specifically used to firmly clamp the flange to ensure that the flange will not fall off or shift during the flipping process. In actual applications, the multiple clamping positions 314313 on the flip mechanism 3 can be adjusted according to different flanges, so that the system can easily adapt to the grinding needs of flanges of different specifications and sizes, improve the flexibility and scope of application of the system, and provide strong support for enterprises to cope with changing market demands.

[0063] In actual applications, the first grinding mechanism 2 and the second grinding mechanism 4 are respectively used to grind different positions of the flange, for example, the first grinding mechanism 2 is used to grind the plane of the flange, and the second grinding mechanism 4 can be used to grind the inner circle of the flange. In actual operation, the flange to be polished is first placed on the first conveying device 100, and is conveyed by the first conveying device 100. When the flange passes through the first grinding mechanism 2, the surface of the flange is polished by the first grinding mechanism 2. After the first grinding mechanism 2 is finished, the flange continues to be conveyed by the first conveying device 100, and the first conveying device 100 sends the flange into the clamping position 314313 of the flipping mechanism 3. The clamping position 314313 rotates under the drive of the rotating member 31, thereby flipping the flange 180 degrees, so that the flange enters the second conveying device 210200. The second conveying device 210200 conveys the flange to the bottom of the second grinding mechanism 4 for grinding at other positions, and sends it out after the grinding is completed. The system uses the flip mechanism 3 so that all surfaces of the flange can be fully polished, avoiding the problem of uneven polishing caused by the inconvenience of flange flipping in the traditional polishing method, thereby significantly improving the polishing quality and product consistency. In addition, the use of the flip mechanism 3 avoids the use of a manipulator for complex and time-consuming flipping operations, making the entire polishing process smoother and more efficient. This not only shortens the production cycle, but also greatly improves the overall production capacity of the production line. In addition, the system can realize automated polishing, reduce manual participation, reduce the labor intensity of workers, and also reduce the defective rate caused by improper manual operation, thereby reducing production costs.

[0064] Example 2

[0065] This embodiment is improved on the basis of embodiment 1.

[0066] like Figure 1-Figure 7 As shown, in this embodiment, the rotating member 31 includes a connecting rod 230312 and a dial 311, the connecting rod 230312 is arranged on the frame 1 along the width direction of the frame 1, and the connecting rod 230312 is rotatably connected to the frame 1;

[0067] Two dials 311 are provided, and the two dials 311 are respectively fixed at opposite ends of the connecting rod 230312; a plurality of levers 32 are provided on the edge of each dial 311, and the plurality of levers 32 are evenly distributed on the dial 311 along the circumference of the dial 311, and a snap-in position 314313 is formed between two adjacent levers 32, and the snap-in positions 314313 on the two dials 311 correspond to each other.

[0068] In this embodiment, the connecting rod 230312 is firmly arranged on the frame 1 along the width direction of the frame 1, and is rotatably connected to the frame 1 through a bearing or other rotating connecting member, ensuring that the connecting rod 230312 can rotate freely around its own axis. Two dials 311 are provided, which are respectively fixed at both ends of the connecting rod 230312 to form a symmetrical layout. This design can enhance the stability of the rotating member 31, so that the clamping positions 314313 on the two dials 311 can clamp the flange at the same time, ensuring the stability of the flange flipping. A plurality of levers 32 are designed on the edge of each dial 311, and these levers 32 are evenly distributed along the circumference of the dial 311, and a clamping position 314313 for clamping the flange is naturally formed between two adjacent levers 32. The clamping positions 314313 on the two dials 311 correspond to each other, ensuring that the flange can maintain a stable position during the flipping process and will not fall off due to bumps or vibrations.

[0069] In the actual working process, when the first conveying device 100 conveys the flange to be polished to the flipping mechanism 3, the flange will be accurately inserted into the corresponding snap-in positions 314313 of the two dials 311. Subsequently, the connecting rod 230312 is driven to rotate by a driving device (such as a motor, a reducer, etc.), thereby driving the two dials 311 to rotate synchronously to realize the flipping of the flange. After the flipping is completed, the flange will be smoothly taken away by the second conveying device 210200 and sent to the next process for polishing or processing.

[0070] The double dial 311 design cooperates with the evenly distributed levers 32 so that the flange can always maintain a stable position during the flipping process, avoiding the flange falling off or damage caused by unstable flipping, and improving the stability and reliability of the flipping.

[0071] Example 3

[0072] This embodiment is improved on the basis of Embodiment 2.

[0073] like Figure 1-Figure 7 As shown, in this embodiment, each of the shifting rods 32 is provided with a plurality of pulleys 321 , the pulleys 321 are rotatably connected to the shifting rods 32 , and the plurality of pulleys 321 are provided on the shifting rods 32 along the length direction of the shifting rods 32 .

[0074] The pulley 321 and the lever 32 are installed in a rotationally connected manner. These pulleys 321 are arranged on the lever 32 in an orderly manner along the length direction of the lever 32, forming a series of efficient rolling support systems. The design of the pulley 321 greatly reduces the direct contact friction between the flange and the lever 32 during the flipping process. Since the pulley 321 can rotate freely, when the flange contacts the pulley 321 and generates relative motion, the pulley 321 will roll with it, thereby converting the sliding friction into rolling friction. This transformation not only significantly reduces the friction resistance, but also greatly reduces the heat and wear generated by friction, thereby extending the service life of the flip mechanism 3.

[0075] In addition, during the use process, the pulley 321 enables the flange to slide onto the lever 32 synchronously, and then the flange is flipped after the dial 311 is rotated. The distribution of multiple pulleys 321 along the length direction of the lever 32 provides a more uniform and stable support for the flange. During the flipping process, even if the flange is subjected to uneven external forces, the pulley 321 can maintain the balance of the flange through its own rolling adjustment, thereby ensuring a smooth flipping process.

[0076] Example 4

[0077] This embodiment is improved on the basis of embodiment 3.

[0078] like Figure 1-Figure 7 As shown, in this embodiment, a double-wheel guide rod 5 is provided on the frame 1, and both ends of the double-wheel guide rod 5 are respectively exposed outside the frame 1, and the connecting rod 230312 is connected to the double-wheel guide rod 5 through a first transmission belt 51.

[0079] The connecting rod 230312 is connected to the double-wheel guide rod 5 through the first transmission belt 51. As a common transmission device, the transmission belt has multiple functions such as power transmission, noise reduction, and shock absorption. In the present application, it can smoothly transmit the power of the driving device to the connecting rod 230312, thereby driving the dial 311 and the flange to flip.

[0080] Example 5

[0081] This embodiment is improved on the basis of embodiment 1.

[0082] like Figure 1-Figure 7 As shown, in this embodiment, the first grinding mechanism 2 includes a grinding drive mechanism 22, a screw rod 24, a sleeve 23 and a grinding plate 25, and the screw rod 24 is rotatably arranged on the frame 1, and the screw rod 24 spans above the first conveying device 100;

[0083] The grinding drive mechanism 22 is fixed on the frame 1, and the output end of the grinding drive mechanism 22 is fixedly connected to the screw rod 24; the sleeve 23 is arranged on the screw rod 24, the sleeve 23 is threadedly connected to the screw rod 24, and the grinding plate 25 is arranged at the bottom of the sleeve 23.

[0084] In actual use, the screw 24 drives the sleeve 23 and the grinding plate 25 below to perform precise grinding by rotating. The sleeve 23 and the screw 24 are tightly connected by threads, and can move along the axial direction of the screw 24 as it rotates, thereby driving the grinding plate 25 to adjust its position. The grinding plate 25 is the main working part for performing the grinding task, and its surface is usually covered with wear-resistant material to enhance the grinding effect.

[0085] The working process of the first grinding mechanism 2 is as follows: when the grinding drive mechanism 22 is started, its output end drives the screw 24 to start rotating. Since the sleeve 23 and the screw 24 are connected by threads, the sleeve 23 moves along the axial direction of the screw 24 as the screw 24 rotates. The movement of the sleeve 23 drives the grinding plate 25 to adjust its position, so that the grinding plate 25 can contact different positions of the flange and grind the flange on the first conveying device 100.

[0087] This embodiment is improved on the basis of embodiment 4.

[0088] like Figure 1-Figure 7 As shown, in this embodiment, a first pulley 21 is provided at one end of the screw rod 24 , the first pulley 21 is exposed outside the frame 1 , and the first pulley 21 is connected to the double-wheel guide rod 5 through a second transmission belt 52 .

[0089] In actual application, the grinding drive mechanism 22 drives the screw 24 to rotate, and the screw 24 drives the first pulley 21 to rotate, thereby driving the double-wheel guide rod 5 to rotate through the second transmission belt 52, and the rotation of the double-wheel guide rod 5 can drive the connecting rod 230312 to rotate through the first transmission belt 51.

[0090] Example 7

[0091] This embodiment is improved on the basis of embodiment 1.

[0092] like Figure 1-Figure 7As shown, in this embodiment, the second conveying device 210200 includes a first bracket, a conveying belt, a roller 220 and a connecting rod 230312, the first bracket is arranged on the frame 1, two first brackets are arranged, each of the first brackets is provided with a connecting rod 230312, the connecting rod 230312 is rotatably matched with the first bracket, the roller 220 is fixed on the connecting rod 230312, and the conveying belt is arranged on the roller 220;

[0093] The frame 1 is further provided with a second driving device 240 , and an output end of the second driving device 240 is fixedly connected to the connecting rod 230312 .

[0094] The roller 220 is firmly fixed on the connecting rod 230312 and rotates with the rotation of the connecting rod 230312. The conveyor belt is tightly wound on the roller 220. When the roller 220 rotates, the conveyor belt moves accordingly, thereby realizing the conveyance of the workpiece. When the second driving device 240 is started, its output end drives the connecting rod 230312 to rotate, thereby driving the roller 220 and the conveyor belt to start moving. The workpiece (flange) is placed on the conveyor belt and is transported to the designated processing position as the conveyor belt moves. The second driving device 240 drives the connecting rod 230312 and the roller 220 to rotate, thereby driving the conveyor belt to move, thereby realizing rapid and continuous conveyance of the workpiece, greatly improving production efficiency.

[0095] Example 8

[0096] This embodiment is improved on the basis of embodiment 1.

[0097] like Figure 1-Figure 7 As shown, in this embodiment, the second grinding mechanism 4 includes a second bracket 41, and the second bracket 41 spans above the second conveying device 210200;

[0098] The second bracket 41 is provided with a grinding disc 42, and the grinding disc 42 is pivotally connected to the second bracket 41; the grinding disc 42 is provided with a first bevel gear 421; the second bracket 41 is also provided with a transmission shaft 412, and the transmission shaft 412 is pivotally connected to the second bracket 41; one end of the transmission shaft 412 is provided with a second bevel gear 411, and the second bevel gear 411 is meshed with the first bevel gear 421;

[0099] A second pulley is also provided at one end of the connecting rod 230312 , and the transmission shaft 412 is connected to the second pulley via a third transmission belt 413 .

[0100] The transmission shaft 412 is pivotally connected to the second bracket 41, and is provided with a second bevel gear 411 meshed with the first bevel gear 421. When the transmission shaft 412 rotates, the grinding disc 42 is driven to rotate synchronously through the meshing action of the bevel gears. The third transmission belt 413 is connected between the transmission shaft 412 and the second pulley, and is used to transmit the rotational power of the connecting rod 230312 (i.e., the driving part of the second conveying device 210200) to the transmission shaft 412, thereby driving the grinding disc 42 to rotate. When the second conveying device 210200 is started, the connecting rod 230312 drives the roller 220 and the conveying belt to rotate, thereby realizing the continuous conveying of the workpiece. At the same time, the second pulley on the connecting rod 230312 transmits power to the transmission shaft 412 through the third transmission belt 413. When the transmission shaft 412 rotates, the second bevel gear 411 thereon meshes with the first bevel gear 421 on the grinding disc 42, driving the grinding disc 42 to rotate around the pivot. When the workpiece moves on the conveyor belt, it passes under the grinding disc 42 and is ground by the working surface of the grinding disc 42 .

[0101] In this embodiment, a lifting mechanism 6 is further provided on the frame 1, and the lifting mechanism 6 is provided below the second grinding mechanism 4;

[0102] The lifting mechanism 6 includes two push rods 61 hinged to each other, and the middle parts of the two push rods 61 are hinged to each other; the bottom of any one of the push rods 61 is hinged to the frame 1, and the other push rod 61 is slidably matched with the frame 1 through a slide cylinder 63; a telescopic rod 64 is provided on the frame 1, and the output end of the telescopic rod 64 is fixedly connected to the slide cylinder 63;

[0103] A push plate 62 is provided on the top of the two push rods 61, and the push rods 61 are hinged to each other;

[0104] The lifting mechanisms 6 are provided with two, and the push rods 61 of the two lifting structures are respectively located on both sides of the conveyor belt.

[0105] The second grinding mechanism 4 is arranged above the second conveying device 210200, and is used for grinding the workpiece passing on the conveyor belt.

[0106] Two mutually hinged push rods 61 form a scissors-like structure. This design enables the push rod 61 to achieve telescopic movement in the vertical direction. A telescopic rod 64 (which can be a cylinder, a hydraulic cylinder, etc.) is installed on the frame 1, and its output end is fixedly connected to the slide 63. The telescopic movement of the telescopic rod 64 can drive the slide 63 to move, and the movement of the slide 63 drives the bottom of one of the push rods 61 to move, thereby achieving the function of changing the position of the top of the push rod 61, that is, making the push rod 61 rise and fall. The equipment is provided with a lifting mechanism 6 on both sides of the conveyor belt. In this way, the two lifting mechanisms 6 can work synchronously to ensure that the workpiece (flange) remains in a horizontal state during the lifting process.

[0107] During operation, when the telescopic rod 64 is extended, it pushes the slide 63 to move, so the push rod 61 connected to the slide 63 also moves. Since the two push rods 61 are hinged in the middle, they will form an upward thrust to lift the push plate 62, and the push rod 61 will lift the flange on the conveyor belt. Conversely, when the telescopic rod 64 is retracted, the top of the push rod 61 will move downward, and the push plate 62 and the workpiece will also drop.

[0108] By controlling the extension amount of the telescopic rod 64, the height position of the workpiece can be accurately adjusted so that the workpiece (flange) can be connected to the second grinding mechanism 4 to achieve grinding of the flange.
