Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping device technology, specifically a forging polishing clamping device. Background Technology
[0002] Forgings are key basic components in the machinery manufacturing field, and their quality directly affects the performance and reliability of the entire mechanical product. Among the many forging processing steps, polishing is an indispensable step to improve the surface quality of forgings, enhance their appearance, and meet specific application requirements (such as reducing the coefficient of friction and improving corrosion resistance). A search revealed a patent, CN223160713U, for example, a clamping fixture for polishing flange forgings. This fixture includes a worktable with a support plate fixedly connected to its surface. A motor A is fixedly connected to one side of the support plate. A clamping assembly is fixedly connected to the telescopic end of motor A, passing through the side wall of the support plate. The clamping assembly includes a fixed cylinder fixedly connected to the telescopic end of motor A. The fixed cylinder has a cavity, and a cylindrical seat is fixedly connected to the inner wall of the cavity via a support rod. Several through slots are evenly spaced on the surface of the cylindrical seat. Clamping blocks are slidably connected to both sides of each through slot, and two clamping blocks are fixedly connected by a spring. A limit frame is slidably connected to the surface of the cylindrical seat. This invention has the advantage of simultaneously clamping and fixing multiple flange forgings of various sizes, improving polishing efficiency and effectiveness. Although the current equipment can fix and polish multiple forgings at the same time, when fixing flange forgings, the flange forgings need to be placed precisely on one side of the fixing block and the position needs to be accurate before fixing. This undoubtedly increases the difficulty and complexity of operation, prolongs the clamping time, and thus reduces work efficiency. Utility Model Content
[0003] The purpose of this invention is to provide a forging polishing clamping device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a forging polishing clamping device, including a worktable, an mounting plate fixedly installed on the top of the worktable, a grinding structure provided at the bottom of the mounting plate, a fixing cylinder provided below the grinding structure, forging bodies evenly arranged on the outside of the fixing cylinder, each forging body being connected to the fixing cylinder by a fixing component, a fixing seat installed at one end of the fixing cylinder, and the fixing seat being fixedly installed on the top of the worktable; A fixed limiting block is provided on the side wall of the forging body near the fixed seat. The fixed limiting block is fixedly installed on the outer wall of the fixed cylinder. A sliding limiting block is provided on the side wall of the forging body away from the fixed seat. The sliding limiting block is slidably installed inside the fixed cylinder. Both the sliding limiting block and the fixed limiting block are evenly distributed in a ring array.
[0005] As a further preferred embodiment of this technical solution, the fixing component includes a fixing block that is slidably installed inside the fixing cylinder. The fixing blocks are evenly distributed in a ring array. Each fixing block has a first limiting plate fixedly connected to both sides, and a first spring is installed at the bottom of each fixing block.
[0006] As a further preferred embodiment of this technical solution, both ends of the fixing block are set to be arc-shaped.
[0007] As a further preferred embodiment of this technical solution, the entire outer surface of the top of the fixing block is set to an arc shape.
[0008] As a further preferred embodiment of this technical solution, each of the fixed blocks is rotatably equipped with a pulley inside.
[0009] As a further preferred embodiment of this technical solution, a rack plate is fixedly connected to the bottom end of a portion of the fixed block, a gear is meshed with one side of the rack plate, a rotating shaft is fixedly installed on one side of the gear, a rotating plate is fixedly installed at the end of the rotating shaft away from the gear, and guide portions are distributed in a ring array on the outer wall of the rotating plate, with the guide portions located at one end of the sliding limit block.
[0010] As a further preferred embodiment of this technical solution, a second limiting plate is fixedly installed at the bottom end of each sliding limiting block, each second limiting plate is slidably installed inside the fixed cylinder, and a second spring is provided at the top end of each second limiting plate.
[0011] This utility model provides a forging polishing clamping device, which has the following beneficial effects: This invention, through the setting of sliding and fixed limiting blocks, simplifies the polishing process of forging bodies. First, multiple forging bodies are installed on the outside of a fixed cylinder. The first forging body is pushed towards one side of the fixed base, making it fit against the side wall of the fixed limiting block, which then limits its position. Subsequent forging bodies are then pushed sequentially to one side of the sliding limiting block, which also limits their position. This ensures accurate installation of the forging bodies and avoids the problems of current clamping devices lacking a limiting structure, requiring careful placement during installation, increasing operational difficulty and complexity, extending clamping time, and reducing work efficiency. The use of fixed and sliding limiting blocks to limit the forging bodies simplifies the installation process, thereby improving the polishing efficiency of the forgings.
[0012] This invention features a sliding limit block that automatically slides out during the installation of the forging body. When the first forging body is installed outside the fixing block, causing the fixing block to press into the fixing cylinder, the movement of the fixing block drives the movement of the rack plate. The movement of the rack plate drives the rotation of the gear, which in turn drives the rotation of the rotating shaft. The rotation of the rotating shaft drives the rotation of the rotating plate, which in turn drives the rotation of the guide part. When the guide part rotates, it forces the sliding limit block to move outward and open, allowing the sliding limit block to slide out of the fixing cylinder and thus limit the installation of subsequent forging bodies.

Detailed Implementation
[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] This utility model provides a technical solution: such as Figures 1 to 5 As shown, in this embodiment, a forging polishing clamping device includes a worktable 1, an mounting plate 2 is fixedly installed on the top of the worktable 1, a grinding structure 3 is provided at the bottom of the mounting plate 2, a fixing cylinder 5 is provided below the grinding structure 3, forging bodies 6 are evenly arranged on the outside of the fixing cylinder 5, and each forging body 6 is connected to the fixing cylinder 5 by a fixing component. A fixing seat 4 is installed at one end of the fixing cylinder 5, and the fixing seat 4 is fixedly installed on the top of the worktable 1. A fixed limiting block 19 is provided on the side wall of the forging body 6 near the fixed seat 4. The fixed limiting block 19 is fixedly installed on the outer wall of the fixed cylinder 5. A sliding limiting block 11 is provided on the side wall of the forging body 6 away from the fixed seat 4. The sliding limiting block 11 is slidably installed inside the fixed cylinder 5. Both the sliding limiting block 11 and the fixed limiting block 19 are evenly distributed in a ring array.
[0017] The existing patent CN223160713U discloses a clamping fixture for polishing flange forgings. This patent discloses the worktable 1, mounting plate 2 and grinding structure 3 proposed in this application. The technical means will not be described in detail here. When polishing the forging body 6, first install multiple forging bodies 6 onto the outside of the fixed cylinder 5, push the first forging body 6 toward one side of the fixed seat 4 so that it fits against the side wall of the fixed limiting block 19, and limit it by the fixed limiting block 19. Then, the subsequent forging body 6 is pushed to one side of the sliding limit block 11. The sliding limit block 11 limits it to ensure that the installation position of the forging body 6 is accurate. This prevents the current clamping device from lacking a structure to limit the forging body 6, which requires careful placement during installation, increases the difficulty and complexity of operation, prolongs clamping time, and reduces work efficiency. Limiting the forging body 6 with the fixed limit block 19 and the sliding limit block 11 helps to simplify the installation steps and improve the polishing efficiency of the forging.
[0018] like Figures 1 to 5 As shown, the fixing component includes a fixing block 7 that is slidably installed inside the fixing cylinder 5. The fixing blocks 7 are evenly distributed in a ring array. Each fixing block 7 has a first limiting plate 8 fixedly connected to both sides, and a first spring 9 is installed at the bottom of each fixing block 7.
[0019] When installing the forging body 6, the elastic potential energy of the first spring 9 causes the fixing block 7 to always have an outward tendency, thereby fixing it from the inside to the outside on the inner wall of the forging body 6 through the fixing block 7. The fixing method is simple and convenient, which can further improve the polishing efficiency of the forging.
[0020] like Figure 5 As shown, both ends of the fixing block 7 are set to be arc-shaped.
[0021] When the forging body 6 slides on the outer wall of the fixed cylinder 5, it can be pressed into the fixed cylinder 5 by contacting the arc-shaped end of the fixed block 7, which facilitates quick installation.
[0022] like Figure 5 As shown, the entire outer surface of the top of the fixing block 7 is set to be arc-shaped.
[0023] This helps to increase the contact area between the fixing block 7 and the inner wall of the forging body 6, thereby further enhancing the stability of clamping and reducing the possibility of the forging body 6 sliding.
[0024] like Figure 5 As shown, each fixed block 7 has a pulley 10 rotatably mounted inside it.
[0025] When the forging body 6 slides toward one end of the fixed block 7, the rolling friction of the pulley 10 replaces the original sliding friction, which makes it easier for the operator to slide the forging body 6 into the fixed position and greatly reduces the labor intensity.
[0026] like Figure 5 As shown, a rack plate 18 is fixedly connected to the bottom end of a portion of the fixed block 7. A gear 17 is meshed with one side of the rack plate 18. A rotating shaft 16 is fixedly installed on one side of the gear 17. A rotating plate 14 is fixedly installed at the end of the rotating shaft 16 away from the gear 17. Guide portions 15 are distributed in a ring array on the outer wall of the rotating plate 14. The guide portions 15 are located at one end of the sliding limit block 11.
[0027] When the first forging body 6 is installed outside the fixing block 7 and the fixing block 7 is pressed into the fixing cylinder 5, the movement of the fixing block 7 causes the rack plate 18 to move, the movement of the rack plate 18 causes the gear 17 to rotate, the rotation of the gear 17 causes the rotating shaft 16 to rotate, the rotation of the rotating shaft 16 causes the rotating plate 14 to rotate, the rotation of the rotating plate 14 causes the guide part 15 to rotate, and when the guide part 15 rotates, it forces the sliding limit block 11 to move outward and open, so that the sliding limit block 11 slides out of the fixing cylinder 5 and limits the subsequent forging body 6.
[0028] like Figure 4 and Figure 5 As shown, a second limiting plate 12 is fixedly installed at the bottom of each sliding limiting block 11, and each second limiting plate 12 is slidably installed inside the fixed cylinder 5. A second spring 13 is provided at the top of each second limiting plate 12.
[0029] When installing the forging body 6, when the fixing block 7 moves into the fixing cylinder 5 and causes the sliding limit block 11 to slide out of the fixing cylinder 5, the movement of the sliding limit block 11 causes the second limit plate 12 to move. When the second limit plate 12 moves, it causes the second spring 13 to deform and store elastic potential energy. When the forging body 6 is removed, when the fixing block 7 moves outward and drives the rack plate 18 to move, the rotating plate 14 rotates and drives the guide part 15 to rotate and be offset from the bottom of the sliding limit block 11. At this time, the elastic potential energy is released by the second spring 13 to make the sliding limit block 11 slide into the fixing cylinder 5, preventing the sliding limit block 11 from blocking the sliding path of the forging body 6, so as to facilitate the removal of the forging body 6.
[0030] This utility model provides a forging polishing clamping device, the specific working principle of which is as follows: When polishing the forging body 6, first install multiple forging bodies 6 onto the outside of the fixed cylinder 5, push the first forging body 6 toward one side of the fixed seat 4 so that it fits against the side wall of the fixed limiting block 19, and limit it by the fixed limiting block 19. When the forging body 6 contacts the arc-shaped end, it is pressed into the fixed cylinder 5, and the elastic potential energy of the first spring 9 makes the fixed block 7 always have the tendency to move outward, so that the fixed block 7 is fixed from the inside to the outside on the inner wall of the forging body 6. At the same time, the fixed block 7 moves into the fixed cylinder 5, causing the rack plate 18 to move. The movement of the rack plate 18 causes the gear 17 to rotate. The rotation of the gear 17 causes the rotating shaft 16 to rotate. The rotation of the rotating shaft 16 causes the rotating plate 14 to rotate. The rotation of the rotating plate 14 causes the guide part 15 to rotate. When the guide part 15 rotates, it forces the sliding limit block 11 to move outward and open, so that the sliding limit block 11 slides out of the fixed cylinder 5. Then the subsequent forging body 6 is pushed to one side of the sliding limit block 11, and the sliding limit block 11 limits it to ensure that the installation position of the forging body 6 is accurate. After all the forging bodies 6 are installed, the surface of the forging bodies 6 is polished by the grinding structure 3. After polishing, remove the forging body 6 furthest from the fixed base 4, and then remove the second one. When the forging body 6 separates from the fixed block 7, the first spring 9 releases elastic potential energy to make the fixed block 7 slide outward. Similarly, the movement of the fixed block 7 drives the movement of the rack plate 18, the movement of the rack plate 18 drives the rotation of the gear 17, the rotation of the gear 17 drives the rotation of the rotating shaft 16, the rotation of the rotating shaft 16 drives the rotation of the rotating plate 14, and the rotation of the rotating plate 14 drives the rotation of the guide part 15 to be misaligned with the bottom of the sliding limit block 11. At this time, the second spring 13 releases elastic potential energy to make the sliding limit block 11 slide into the fixed cylinder 5 to prevent the sliding limit block 11 from blocking the sliding path of the forging body 6, making it easier to remove the forging body 6.
