Description

Technical Field

[0001] This invention relates to the field of flange conveying equipment technology, specifically a continuous feeding device for flange processing. Background Technology

[0002] In the large-scale production and processing of flanges, the processing flow usually includes multiple continuous processes such as blank forging, rough turning on a lathe, fine turning, drilling, grinding, and inspection. Efficient transfer of flange workpieces is required between each process. Therefore, continuous conveying equipment is one of the core auxiliary equipment to ensure the smooth operation of the production line.

[0003] Existing flange conveying equipment mostly uses conveyor belts for placement and conveying or fixed clamps for clamping and conveying. During the conveyor belt conveying process, the position of the flange is relatively fixed, making it difficult to rotate and adjust the flange in all directions during the conveying process. Furthermore, because the clamping position is relatively fixed, it will block part of the flange surface, making it difficult for processing and testing equipment to fully operate and inspect the entire flange at the set position, thus affecting the efficiency of production and testing. Summary of the Invention

[0004] The purpose of this invention is to provide a continuous feeding device for flange processing that facilitates omnidirectional adjustment and rotation of the flange during the conveying process, thereby improving production and inspection efficiency and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a continuous feeding device for flange processing, comprising a machine body, a conveying mechanism, and a loading mechanism. The machine body has a conveying cavity. The conveying mechanism includes multiple sets of conveying rods installed within the conveying cavity. Multiple sets of clamping shafts are mounted on the conveying rods. The conveying mechanism can drive the clamping shafts to clamp flanges and control the flanges to rotate around their axes, switching the clamping positions. Simultaneously, it can drive the conveying rods to rotate, enabling the flanges to be flipped, allowing for omnidirectional adjustment and control of the flanges during the conveying process. The loading mechanism is mounted on the machine body and is used to load the flanges to be conveyed one by one onto the conveying rods at designated positions for conveying. It ensures stable connection between the flanges and the clamping shafts and conveying rods during loading, facilitating omnidirectional adjustment and rotation of the flanges during conveying, thereby improving production and inspection efficiency.

[0006] Preferably, the conveying mechanism further includes two sets of sliding frames mounted on the conveying rod. The conveying rod has two sets of first sliding grooves and two sets of second sliding grooves. The two sets of sliding frames are slidably connected to the first sliding grooves on both sides. A sliding block is slidably connected in the second sliding groove. A rotating shaft is rotatably connected to the sliding block. Two sets of clamping shafts are rotatably connected to each set of sliding frames. The conveying rod is provided with a driving component for controlling the movement state of the sliding frames and the sliding blocks. The sliding frames are provided with clamping components for assisting in clamping the upper side of the flange, which facilitates driving the clamping shafts to clamp the flange and control the flange to rotate around the shaft, and switch the clamping position.

[0007] Preferably, the driving component includes a driving rod fixedly installed on the side of the sliding block, a driving tube fixedly connected to the side of the sliding frame, a first sliding cavity communicating with the first sliding groove in the conveying rod, a second sliding cavity communicating with the second sliding groove in the conveying rod, the outer wall of the driving tube slidably connected to the inner wall of the first sliding cavity, and the outer wall of the driving rod slidably connected to the inner wall of the second sliding cavity. Both the first and second sliding cavities are used to store hydraulic oil. A connecting pipe is provided in the conveying rod to connect the first and second sliding cavities, which facilitates control of the movement state of the sliding frame and the sliding block.

[0008] Preferably, the clamping component includes a fixed frame fixedly installed on the sliding frame, a lifting block slidably connected in the vertical direction inside the fixed frame, a clamping plate fixedly connected to the upper side of the lifting block, a bent pipe for connecting the fixed frame and the drive pipe opened in the sliding frame, a spring fixedly connected to the sliding frame, the upper side of the spring being fixedly connected to the bottom surface of the lifting block, and the clamping shaft passing through the clamping plate and movably sleeved with the inner wall of the clamping plate, which facilitates the clamping of the upper side of the flange.

[0009] Preferably, the driving component includes an electric telescopic rod fixedly installed on the conveying rod, a hydraulic cavity is provided inside the conveying rod, the connecting pipe is connected to the hydraulic cavity, and a hydraulic plate is fixedly connected to the telescopic end of the electric telescopic rod. The hydraulic plate is slidably connected to the inner wall of the hydraulic cavity, which facilitates control of the hydraulic pressure in the first sliding cavity and the second sliding cavity.

[0010] Preferably, the conveying mechanism further includes two sets of drive rollers mounted on the machine body. The outer walls of both ends of the drive rollers are respectively connected to conveying chains. The two ends of the conveying rod are respectively rotatably connected to connecting rods that are fixedly connected to the conveying chains on both sides. The two ends of the conveying rod are respectively fixedly connected to drive motors. The output end of the drive motor is coaxially fixedly connected to the connecting rod. A motor is fixedly connected to the sliding frame. The output end of the motor is coaxially fixedly connected to the clamping shaft, which facilitates the conveying rod to perform cyclical conveying and enables the conveying rod to drive the flange to rotate and adjust.

[0011] Preferably, the feeding mechanism includes a mounting frame fixedly installed on the machine body, a storage cylinder inserted into the mounting frame, the storage cylinder for storing flanges to be fed and conveyed, and an output port for outputting the flanges on the bottom side of the storage cylinder, so as to facilitate feeding the flanges to be conveyed one by one to the conveying rod at a set position for conveying operation, while ensuring stable docking of the flanges with the clamping shaft and the conveying rod during the feeding process.

[0012] Preferably, a first tension spring is fixedly connected to the side of the sliding frame and fixedly connected to the first sliding groove, and a second tension spring is fixedly connected to the side of the sliding block and fixedly connected to the second sliding groove. The elastic force of the spring is greater than the elastic force and tension of the first and second tension springs, which facilitates the control of the movement sequence of the sliding block, the sliding frame and the clamping plate. This allows the sliding block and the sliding frame to move with the clamping plate first, and after they are attached to the inner and outer sides of the flange, the clamping plate is then controlled to move to clamp and fix the upper side of the flange.

[0013] Preferably, the bottom of the clamping plate has multiple sets of rolling grooves, and rolling balls are rolled in the rolling grooves. This helps to reduce friction on the flange surface while ensuring clamping strength, so that the flange can be rotated and adjusted under the drive of the clamping shaft.

[0014] Preferably, the machine body has an output slot, the upper end of which is connected to the bottom of the conveying cavity, so as to facilitate the output of the processed flange from the bottom.

[0016] This invention provides a continuous feeding device for flange processing, which solves the problems of existing continuous feeding devices for flange processing having a simple structure, making it difficult to flexibly adjust and control the flanges, thus affecting production and inspection efficiency. The device controls the clamping shaft to hold the flange and rotate it around the shaft via a conveying mechanism, switching the clamping position. Simultaneously, it can drive the conveying rod to rotate, enabling the flange to be flipped. This allows for omnidirectional adjustment and control of the flange during the conveying process, facilitating inspection, grinding, and other operations on the flange during transport, thus improving production and inspection efficiency. The feeding mechanism feeds the flanges one by one onto the conveying rod at a set position, ensuring stable connection between the flange, clamping shaft, and conveying rod during the feeding process.

[0029] Please see Figures 1-10 This invention provides a technical solution: a continuous feeding device for flange processing, comprising a body 1, a conveying mechanism, and a loading mechanism.

[0030] The conveying mechanism also includes two sets of sliding frames 5 mounted on the conveying rod 3.

Ball bearings 38 are slidably connected in the rolling grooves 37. A bent tube 21 for connecting the fixed frame 18 and the drive tube 13 is opened inside the sliding frame 5. A spring 22 is fixedly connected to the sliding frame 5. The upper side of the spring 22 is fixedly connected to the bottom surface of the lifting block 19. The clamping shaft 4 passes through the clamping plate 20 and is movably sleeved with the inner wall of the clamping plate 20.

[0033] The driving component 10 includes an electric telescopic rod 23 fixedly installed on the conveying rod 3. A hydraulic cavity 24 is opened inside the conveying rod 3. A connecting pipe 16 is connected to the hydraulic cavity 24. A hydraulic plate 25 is fixedly connected to the telescopic end of the electric telescopic rod 23. The hydraulic plate 25 is slidably connected to the inner wall of the hydraulic cavity 24. A first tension spring 35 fixedly connected to the first slide groove 6 is fixedly connected to the side of the sliding frame 5. A second tension spring 36 fixedly connected to the second slide groove 7 is fixedly connected to the side of the sliding block 8.

[0034] The conveying mechanism also includes two sets of drive rollers 26 mounted on the machine body 1. The outer walls of the two ends of the drive rollers 26 are respectively connected to the conveying chains 27. The two ends of the conveying rods 3 are respectively rotatably connected to the connecting rods 28 which are fixedly connected to the conveying chains 27 on both sides. The two ends of the conveying rods 3 are respectively fixedly connected to the drive motors 29. The output end of the drive motors 29 is coaxially fixedly connected to the connecting rods 28. The sliding frame 5 is fixedly connected to the motor 30. The output end of the motor 30 is coaxially fixedly connected to the clamping shaft 4.

[0035] Working principle: Select a storage cylinder 32 of appropriate size and install it on the mounting frame 31. Place the flange 40 to be conveyed and processed into the storage cylinder 32. The bottom of the mounting frame 31 is provided with two sets of horizontal support rods, which can support the bottom flange 40. At the same time, the position between the two sets of support rods can expose the opening in the middle of the flange 40, so that the rotating shaft 9 can be inserted into the opening in the middle of the flange 40 as it moves with the conveyor chain 27. Start the drive roller 26 to drive the conveyor chain 27 to carry out transmission and conveying, so that multiple sets of conveyor rods 3 can be circulated and transmitted. The figure only shows a shorter length of equipment. In the actual production process, the length of the conveyor chain 27 can be increased as needed, and the number and spacing of the conveyor rods 3 can be adjusted to adapt to the actual production process.

[0036] The conveying rod 3 flips upwards from the bottom of the storage cylinder 32, allowing the two sets of rotating shafts 9 in the middle to insert into the openings in the middle of the flange 40. As the conveying rod 3 moves, it continuously pushes the lowermost flange 40 to slide horizontally out of the mounting bracket 31 and storage cylinder 32 from the side output port 33. Then, the electric telescopic rod 23 drives the hydraulic plate 25 downwards, drawing hydraulic oil from the first sliding chamber 14 and the second sliding chamber 15 into the hydraulic chamber 24. This causes the internal rotating shafts 9 to slide gradually towards both ends of the conveying rod 3 along with the sliding block 8 and the drive rod 12, supporting the inner wall of the flange 40. Simultaneously, the sliding frame 5, driven by the drive pipe 13, clamps the outer wall of the flange 40, thus achieving a clamping effect. Shaft 4 fits against the outer wall of flange 40, achieving stable clamping of flange 40 inside and out. The bottom of flange 40 fits against the surface of conveying rod 3 for support. Then, hydraulic plate 25 continues to draw hydraulic oil from drive pipe 13 into hydraulic chamber 24, causing the pressure in fixed frame 18 to continue to decrease. The elastic force of spring 22 is greater than that of first tension spring 35 and second tension spring 36, so that spring 22 requires greater negative pressure drive when compressed. Clamping plate 20 moves later than sliding block 8 and sliding frame 5. When rotating shaft 9 and clamping shaft 4 have finished clamping flange 40, clamping plate 20 on the upper side of sliding frame 5 has reached above flange 40. At this time, clamping plate 20 moves down, and the top surface of flange 40 can be stably clamped by the bottom ball bearing 38.

[0037] By controlling the motor 30 to drive the clamping shaft 4 to rotate, the flange 40 rotates accordingly. The rotating shaft 9 and the ball bearings 38 reduce the frictional resistance of the flange 40 during its rotation, making it easier for the flange 40 to rotate and change its position. This allows all positions on the upper surface of the flange 40 to be rotated to relatively open and unobstructed areas for processing and inspection. When the flange 40 needs to be flipped, the drive motor 29 is controlled to rotate, causing the conveying rod 3 to rotate 180° relative to the connecting rod 28, thus flipping the flange 40. After flipping, the bottom of the flange 40 is stably supported by the ball bearings 38 on the clamping plate 20. At the same time, the rotating shaft 9 and the clamping shaft 4 on the side can continue to drive the flange 40 to rotate. The position folded by the conveying rod 3 can be rotated to an unobstructed area on the side for processing and inspection. The entire conveying process is highly automated, and the device can convey flanges 40 of different sizes, making it highly practical.

[0038] After the processing or inspection operation is completed, the conveying rod 3 drives the flange 40 to a position below the drive roller 26, flips the flange 40 to be directly below the conveying rod 3, and controls the electric telescopic rod 23 to push the hydraulic plate 25, which delivers the hydraulic oil in the hydraulic chamber 24 to the first sliding chamber 14 and the second sliding chamber 15. At this time, the clamping plate 20 will slide first under the push of the spring 22, reducing the clamping force on the flange 40. Then, the rotating shaft 9 and the clamping shaft 4 on both sides slide in opposite directions at the same time, releasing the clamping state on the inner and outer walls of the flange 40. The flange 40 falls to the output groove 39 at the bottom of the conveying chamber 2 for output, thus completing the conveying process. This process can be repeated to achieve continuous feeding for flange processing.
