Description

Technical Field

[0001] This utility model relates to the field of flange technology, and in particular to a rapid grinding device for small flanges. Background Technology

[0002] A flange, or simply flange, is a disc-shaped metal body with several holes around its perimeter for fixing, used to connect pipes to each other, and is usually located at the end of a pipe. Flanges come in various types, including plate flat-face flanges, necked flat-face flanges, and threaded flanges, etc. The standard size range of common flanges is also extremely wide, ranging from 10mm to 1200mm. For small flanges with smaller volume and lighter weight, manual grinding is usually used, which has low production efficiency. For mass production, mechanical devices are used to improve production efficiency. For example, Chinese patent document CN202420575773.1 discloses a flange grinding device, including a frame, a top frame, and a grinding mechanism. The frame is equipped with a clamping mechanism that can clamp and fix multiple flanges in a ring and a drive assembly that can drive the clamping mechanism to rotate. The top frame is located at the top of the frame, and two hydraulic cylinders a are arranged side by side on the top frame. The grinding mechanism includes a surface grinding assembly for grinding the flange surface and a mounting hole grinding assembly for grinding the flange mounting holes and fixing holes. The surface grinding assembly and the mounting hole grinding assembly are respectively driven and connected to the output end of a hydraulic cylinder a. The aforementioned patent uses a drive assembly to drive the flange fixed on the clamping mechanism to move sequentially below the surface grinding assembly and the mounting hole grinding assembly for grinding, thereby improving processing efficiency. However, for small flanges with a small volume and thin thickness, using the drive assembly for clamping can easily lead to wear or bending, affecting product quality.

[0003] Therefore, it is necessary for those skilled in the art to provide a rapid grinding device for small flanges that can ensure production efficiency while preventing wear on the flanges by the clamping equipment and improving product quality. Utility Model Content

[0004] The purpose of this utility model is to provide a quick grinding device for small flanges, so as to solve the technical problem in the prior art that for small flanges with small volume and thin thickness, clamping with drive components can easily lead to wear or bending, which affects product quality.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rapid grinding device for small flanges, used for grinding flanges. The rapid grinding device for small flanges includes a grinding machine, and the flange is slidably mounted on the grinding machine. Multiple flanges are arranged and vertically stacked within the grinding machine. The grinding machine includes a lifting base and a grinding head rotatably mounted above the lifting base. An installation cavity is formed within the lifting base. A vertical telescopic cylinder is provided at the bottom of the lifting base. A placement channel is provided above the vertical telescopic cylinder within the lifting base. The grinding head faces the placement channel. Multiple flanges are evenly arranged within the placement channel. The grinding head can abut against the flanges. The telescopic rod of the vertical telescopic cylinder extends into the placement channel and abuts against the flanges. A horizontal telescopic cylinder and a discharge channel are provided on the upper surface of the lifting base. The horizontal telescopic cylinder is located on one side of the placement channel, and the discharge channel is located on the other side of the placement channel. The telescopic rod of the horizontal telescopic cylinder can abut against the flanges, and the flanges are slidably mounted within the placement channel.

[0006] Furthermore, the placement channel is detachably installed inside the lifting base, and multiple flanges are installed inside the placement channel and the flanges are connected in cooperation within the placement channel.

[0007] Furthermore, one end of the placement channel extends to the upper plane of the lifting base, and the other end of the placement channel extends above the vertical telescopic cylinder.

[0008] Furthermore, the discharge channel is inclined on the lifting base, and the discharge channel is inclined in a direction away from the placement channel.

[0009] Furthermore, the flange is fitted into the internal cavity of the placement channel. The placement channel has a first opening and a second opening on the side near the grinding head. The first opening faces the discharge channel, and the diameter of the first opening is the same as the diameter of the flange.

[0010] Furthermore, the bottom surface of the first opening is higher than the bottom surface of the discharge channel, while the upper surface of the uppermost flange is higher than the upper surface of the placement channel.

[0011] Furthermore, the second opening is oriented toward the horizontal telescopic cylinder, and the telescopic rod of the horizontal telescopic cylinder passes through the second opening and extends into the placement channel.

[0012] Furthermore, the grinding machine includes a grinding frame, which is disposed above the lifting base. A drive motor is provided on the grinding frame, and the grinding head is disposed on the output shaft of the drive motor. The drive motor drives the grinding head to be rotatably disposed on the grinding frame.

[0013] The beneficial effects of this utility model are as follows: This utility model stacks multiple flanges in a placement channel. Through the cooperation of horizontal and vertical telescopic cylinders, multiple flanges are sequentially conveyed and replaced, ensuring processing efficiency. At the same time, the grinding head is placed above the flanges, so that the processing direction is perpendicular to the upper surface of the flanges. The flanges are connected in the placement channel. During processing, the flanges are pushed against the inner wall of the placement channel by the grinding head, thus ensuring processing stability. The self-weight of the flanges further ensures the stability of the flanges during the grinding process. Compared with the clamping of existing technologies, this utility model does not require clamping, preventing the product surface from being worn, improving product quality, reducing clamping steps, and greatly improving processing efficiency, making it suitable for mass production.

[0020] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Please see Figure 1 , Figure 2This utility model provides a quick grinding device for small flanges, used to grind flanges 20. The quick grinding device for small flanges includes a grinding machine 10, and the flanges 20 are slidably mounted on the grinding machine 10. At the same time, multiple flanges 20 are arranged and vertically stacked in the grinding machine 10.

[0022] Furthermore, the grinding machine 10 includes a grinding frame 14 and a lifting base 12. The grinding frame 14 is positioned above the lifting base 12. The grinding frame 14 is equipped with a telescopic cylinder (not shown in the figure). The telescopic rod of the telescopic cylinder is equipped with a grinding head 11 and a drive motor 13. The grinding head 11 is positioned on the output shaft of the drive motor 13. The telescopic cylinder drives the drive motor 13 and the grinding head 11 to move up and down. At the same time, the drive motor 13 drives the grinding head 11 to rotate, thus completing the grinding operation. The grinding head 11 faces the lifting base 12.

[0023] In use, the flange 20 is movably mounted on the lifting base 12, and the grinding head 11 is used to grind the flange 20.

[0024] Further, please refer to Figure 3 , Figure 4 , Figure 5 The lifting base 12 has a hollow square shell structure with an installation cavity 15 inside. A vertical telescopic cylinder 17 is located at the bottom of the lifting base 12. A placement channel 18 is located above the vertical telescopic cylinder 17 inside the lifting base 12. The placement channel 18 has a hollow square tubular structure, with one end extending to the upper surface of the lifting base 12 and the other end extending above the vertical telescopic cylinder 17. Multiple flanges 20 are evenly arranged and coaxially within the placement channel 18. The telescopic rod of the vertical telescopic cylinder 17 extends into the placement channel 18 and abuts against the flanges 20. In use, the vertical telescopic cylinder 17 pushes the flanges 20 upwards, causing the uppermost flange 20 to move onto the upper surface of the lifting base 12.

[0025] In this embodiment, the grinding head 11 is positioned directly opposite the placement channel 18 and can abut against the flange 20. In use, the grinding head 11 is used to grind the upper surface of the flange 20. By continuously pushing the flange 20, continuous grinding is achieved, which is suitable for mass production.

[0026] In this embodiment, the vertical telescopic cylinder 17 is a hydraulic cylinder, used to ensure the stability of pushing against multiple flanges 20.

[0027] In this embodiment, the upper surface of the uppermost flange 20 is higher than the upper surface of the placement channel 18. Therefore, when the grinding head 11 grinds the flange 20, it can effectively prevent the upper surface of the placement channel 18 from being worn, thus ensuring the stability of the present invention in use.

[0028] In this embodiment, the placement channel 18 is detachably installed inside the lifting base 12. Multiple flanges 20 are installed inside the placement channel 18 and are connected in cooperation within the placement channel 18. In use, the placement channel 18 containing multiple flanges 20 is installed as a whole into the lifting base 12, ensuring quick installation, realizing modular production, and improving production efficiency.

[0029] This invention vertically places multiple flanges 20 within a placement channel 18, with a grinding head 11 positioned above the flanges 20, ensuring the processing direction is perpendicular to the upper surface of the flanges 20. The flanges 20 are connected within the placement channel 18. During processing, the flanges 20, driven by the grinding head 11, push against the inner wall of the placement channel 18, thus ensuring processing stability. Furthermore, the weight of the flanges 20 further guarantees their stability during grinding. Compared to existing clamping methods, this invention eliminates the need for clamping, preventing surface wear and improving product quality. It also reduces clamping steps, significantly increasing processing efficiency and enabling mass production.

[0030] Furthermore, the upper surface of the lifting base 12 is provided with a horizontal telescopic cylinder 16 and a discharge channel 19. The horizontal telescopic cylinder 16 is located on one side of the placement channel 18, and the discharge channel 19 is located on the other side of the placement channel 18. The telescopic rod of the horizontal telescopic cylinder 16 can abut against the flange 20. The flange 20 is slidably set in the placement channel 18. In use, the horizontal telescopic cylinder 16 pushes the flange 20 located at the top of the placement channel 18, causing it to slide into the discharge channel 19 to realize material replacement.

[0031] In this embodiment, the discharge channel 19 is inclined on the lifting base 12, and the discharge channel 19 is inclined in a direction away from the placement channel 18, so as to ensure that the flange 20 can be discharged quickly.

[0032] In this embodiment, the horizontal telescopic cylinder 16 is a pneumatic cylinder, used to ensure the speed and stability of pushing the uppermost flange 20.

[0033] Furthermore, the flange 20 is fitted into the internal cavity of the placement channel 18. The placement channel 18 has a first opening 181 and a second opening 182 on the side near the grinding head 11. The first opening 181 faces the discharge channel 19, and its diameter is the same as the diameter of the flange 20. Simultaneously, the bottom surface of the first opening 181 is higher than the bottom surface of the discharge channel 19 to ensure that the flange 20 can smoothly enter the discharge channel 19 from the placement channel 18. The second opening 182 faces the horizontal telescopic cylinder 16. The telescopic rod of the horizontal telescopic cylinder 16 passes through the second opening 182 and extends into the placement channel 18 to ensure that the flange 20 can be smoothly pushed out of the placement channel 18.

[0034] In use, the vertical telescopic cylinder 17 is used to push the flange 20 upward from the bottom of the multiple flanges 20, so that the upper surface of the uppermost flange 20 extends above the upper surface of the lifting base 12, which is convenient for grinding. At the same time, the bottom of the uppermost flange 20 is higher than the bottom surface of the first opening 181. Then, the horizontal telescopic cylinder 16 is used to push the uppermost flange 20 into the discharge channel 19 to complete the discharge.

[0035] The specific operation method of this utility model is as follows: Step 1: Evenly arrange multiple flanges 20 in the placement channel 18, then install the placement channel 18 into the lifting base 12, start the vertical telescopic cylinder 17 to push the flanges 20 upward from the bottom of the multiple flanges 20, start the grinding head 11 to grind the flange 20 located at the top, and finally start the horizontal telescopic cylinder 16 to push the flange 20 located at the top into the discharge channel 19 to complete the rapid grinding.

[0036] This invention stacks multiple flanges 20 within a placement channel 18. A horizontal telescopic cylinder 16 and a vertical telescopic cylinder 17 work together to sequentially transport and change the flanges 20, ensuring processing efficiency. A grinding head 11 is positioned above the flanges 20, making the processing direction perpendicular to the upper surface of the flanges 20. The flanges 20 are connected within the placement channel 18. During processing, the flanges 20 are pushed against the inner wall of the placement channel 18 by the grinding head 11, ensuring processing stability. The weight of the flanges 20 further ensures their stability during grinding. Compared to existing clamping methods, this invention eliminates the need for clamping, preventing surface wear and improving product quality. It also reduces clamping steps, significantly increasing processing efficiency and making it suitable for mass production.
