Description

Technical Field

[0001] This utility model relates to the field of calibration device technology, and in particular to a high-precision aluminum profile calibration machine. Background Technology

[0002] Aluminum extruded profiles are produced through high-temperature extrusion and cooling. Due to differences in product structure and cooling rates at different locations, the final product has different shapes and dimensions, resulting in some form and position tolerances. To salvage products with such non-compliant form and position tolerances, manual reshaping is required for correction.

[0003] The prior art patent CN218656197U discloses an aluminum profile straightening mechanism, which uses a shaping fixture slidably mounted on a platform guide rail to perform torsion and pressing shaping according to the actual position and dimensions of the product. While hydraulic power replaces manual twisting and shaping, reducing labor intensity and improving shaping efficiency and yield, its fixed cavity shape only fits aluminum profiles of specific shapes, making it difficult to adapt to the straightening needs of aluminum profiles of different specifications and shapes. Furthermore, the long length of the aluminum profiles makes installation and disassembly inconvenient. To address these issues, a high-precision aluminum profile straightening machine is proposed. Utility Model Content

[0004] The purpose of this application is to provide a high-precision aluminum profile straightening machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a high-precision aluminum profile straightening machine, comprising a table, a first base and a second base slidably disposed on the top of the table, the top of the first base and the second base being movably disposed with a cavity via a snap-fit ​​mechanism, the snap-fit ​​mechanism comprising two fixed plates, both of the fixed plates being U-shaped, each of the two fixed plates having a sliding hole on its opposite side, each of the two sliding holes having a locking block slidably installed in its sliding hole, each of the two sides of the cavity having a locking groove, the two locking blocks being connected by a linkage assembly, a lower U-shaped plate being fixedly installed on the side of the first base, an upper U-shaped plate being fixedly installed on the top of the lower U-shaped plate, each of the lower U-shaped plate and the upper U-shaped plate having a feeding mechanism on their opposite inner walls, the feeding mechanism comprising two U-shaped blocks, the two U-shaped blocks being controlled by a lifting assembly, each of the two U-shaped blocks having a rotatable feeding roller, the two feeding rollers being connected by a reverse rotation assembly.

[0006] Preferably, the linkage assembly includes two sliding plates. A transmission cavity is provided in the first base. Both sliding plates are slidably installed in the transmission cavity. Racks are fixedly installed on the opposite sides of the two sliding plates. A rotating shaft is rotatably installed on the opposite inner wall of the transmission cavity. A gear is fixedly sleeved on the outer circumferential wall of the rotating shaft. Two connecting holes are provided on the top inner wall of the transmission cavity. Connecting plates are slidably installed in the two connecting holes. The bottoms of the two connecting plates are fixedly connected to the tops of the two sliding plates, and the tops of the two connecting plates are fixedly connected to the sides of the two locking blocks, respectively. A pull ring is provided on the side of one of the connecting plates.

[0007] Preferably, the inner walls of the transmission cavity are fixedly installed with limit shafts, the sides of the two slides and the two racks are provided with limit holes, the ends of the two limit shafts extend into the two limit holes respectively, and a return spring is sleeved on the two limit shafts.

[0008] Preferably, the lifting assembly includes two cylinders, which are respectively fixedly installed on the sides of the lower U-shaped plate and the upper U-shaped plate that are far apart from each other, and the output ends of the two cylinders are respectively fixedly connected to the sides of the two U-shaped blocks.

[0009] Preferably, the reverse rotation assembly includes two drive shafts, each of the two U-shaped blocks has a square cavity, one end of each drive shaft is rotatably mounted on the inner side wall of the two U-shaped blocks, the other end of each drive shaft extends into the two square cavities and is fixedly sleeved with a driven bevel gear, and the two feed rollers are fixedly sleeved on the outer peripheral wall of the two drive shafts.

[0010] Preferably, each of the two square cavities has a rotating hole on its inner wall. Two spline sleeves are rotatably installed in each of the four rotating holes. A drive bevel gear is fixedly sleeved on the outer periphery of each of the two spline sleeves. A spline shaft is commonly sleeved in both spline sleeves. The two ends of the spline shaft are rotatably installed on the inner walls of the lower U-shaped plate and the upper U-shaped plate, respectively. A drive motor is fixedly installed at the bottom of the lower U-shaped plate, and the output shaft of the drive motor is connected to the bottom end of the spline shaft.

[0011] Preferably, protective gaskets are provided on the outer peripheral walls of both feed rollers.

[0012] In summary, the technical effects and advantages of this utility model are as follows: In this invention, pulling the pull ring moves one side of the slide plate, and the meshing transmission of the rack and pinion causes the other side of the slide plate to move in the opposite direction, so that the two connecting plates and two locking blocks can extend and retract synchronously, quickly releasing the limit on the cavity. After the other cavity is placed, pushing the pull ring resets the cavity. The elasticity of the reset spring ensures that the locking block is always embedded in the cavity slot when there is no external force, ensuring the reliability of the cavity fixation. Even when the equipment vibrates during operation, the cavity can be kept stable.

[0013] In this invention, a drive motor rotates a splined shaft, which in turn drives a splined sleeve to rotate via spline engagement. The driving bevel gear rotates with the splined sleeve and drives the driven bevel gear to rotate, ultimately causing the upper and lower drive shafts to rotate in opposite directions, thus enabling the feed rollers to clamp and transport the aluminum profile. The meshing transmission of the bevel gears changes the direction of power transmission, ensuring that the upper and lower feed rollers can generate opposite rotational directions, thereby forming a clamping force and driving force on the aluminum profile.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Example: Reference Figures 1-5 The high-precision aluminum profile straightening machine shown includes a table 1. A first base 2 and a second base 3 are slidably mounted on the top of the table 1. Specifically, a centerless rotary actuator is mounted on the second base 3. The working principle and installation method of the centerless rotary actuator, as well as the connection method between the table 1 and the first and second bases 2 and 3, can be found in the prior art patent with publication number CN218656197U, and will not be elaborated here. A cavity 4 is movably mounted on the top of the first and second bases 2 and 3 via a snap-fit ​​mechanism. The snap-fit ​​mechanism includes two fixing plates 5, both of which are U-shaped. Each fixed plate 5 has a sliding hole on its opposite side, and a locking block 6 is slidably installed in each of the two sliding holes. Both sides of the cavity 4 have a locking groove. The two locking blocks 6 are connected by a linkage component. A lower U-shaped plate 15 is fixedly installed on the side of the first base 2. An upper U-shaped plate 16 is fixedly installed on the top of the lower U-shaped plate 15. Feeding mechanisms are provided on the opposite inner walls of the lower U-shaped plate 15 and the upper U-shaped plate 16. The feeding mechanism includes two U-shaped blocks 18. The two U-shaped blocks 18 are controlled by a lifting component. Feeding rollers 19 are rotatably installed in each of the two U-shaped blocks 18. The two feeding rollers 19 are connected by a reverse rotation component.

[0019] With the above structure, during use, the two locking blocks 6 can be driven to move synchronously towards or away from each other through the action of the locking mechanism, thereby realizing the function of quick loading and unloading of the cavity 4. Moreover, through the action of the locking blocks 6, the stability of the cavity 4 during use can be guaranteed and the correction effect can be improved. Through the setting of the feeding mechanism, the two feeding rollers 19 can be made to fit against the upper and lower sides of the aluminum profile. Through the reverse rotation of the two feeding rollers 19, the aluminum profile is driven to feed or discharge horizontally, which makes it convenient for workers to pick up and put down the aluminum profile.

[0020] like Figure 2 and Figure 3As shown, the linkage assembly includes two sliding plates 8. A transmission cavity is formed inside the first base 2. Both sliding plates 8 are slidably installed in the transmission cavity. Racks 9 are fixedly installed on opposite sides of the two sliding plates 8. A rotating shaft 10 is rotatably installed on the opposite inner wall of the transmission cavity. A gear 11 is fixedly sleeved on the outer circumferential wall of the rotating shaft 10. Two connecting holes are formed on the top inner wall of the transmission cavity. Connecting plates 7 are slidably installed in both connecting holes. The bottoms of the two connecting plates 7 are fixedly connected to the tops of the two sliding plates 8 respectively. The top is fixedly connected to both sides of the two locking blocks 6. A pull ring 14 is provided on the side of one of the connecting plates 7. Limiting shafts 12 are fixedly installed on the opposite inner walls of the transmission cavity. Limiting holes are opened on the sides of the two sliding plates 8 and the two racks 9. The ends of the two limiting shafts 12 extend into the two limiting holes respectively. A return spring 13 is sleeved on both limiting shafts 12. Specifically, one end of the return spring 13 is fixedly installed on the side of the sliding plate 8, and the other end of the return spring 13 is fixedly installed on the inner wall of the side of the transmission cavity.

[0021] In this embodiment, pulling the pull ring 14 moves one side of the slide plate 8. The meshing transmission of the rack 9 and the gear 11 causes the other side of the slide plate 8 to move in the opposite direction, so that the two connecting plates 7 and the two locking blocks 6 can extend and retract synchronously, quickly releasing the limit on the cavity 4. After the other cavity 4 is placed, the pull ring 14 is pushed to reset. The elasticity of the reset spring 13 ensures that the locking block 6 is always embedded in the cavity 4 slot when there is no external force, ensuring the reliability of the cavity 4 fixation. Even when the equipment vibrates during operation, the cavity 4 can be kept stable.

[0022] like Figure 4 As shown, the lifting assembly includes two cylinders 17, which are fixedly installed on the sides of the lower U-shaped plate 15 and the upper U-shaped plate 16 respectively, and the output ends of the two cylinders 17 are fixedly connected to the sides of the two U-shaped blocks 18 respectively.

[0023] In this implementation scheme, the cylinder 17, through the extension and retraction of the output shaft, drives the U-shaped block 18 to rise and fall, adjusting the distance between the upper and lower feed rollers 19 to accommodate aluminum profiles of different thicknesses. This adjustment method offers rapid response and precise control, enabling quick matching of aluminum profiles of various specifications.

[0024] like Figure 4 and Figure 5As shown, the reverse rotation assembly includes two drive shafts 21. Each of the two U-shaped blocks 18 has a square cavity. One end of each drive shaft 21 is rotatably mounted on the inner side wall of the two U-shaped blocks 18. The other end of each drive shaft 21 extends into the two square cavities and is fixedly fitted with a driven bevel gear 26. Two feed rollers 19 are fixedly fitted onto the outer periphery of each drive shaft 21. Rotating holes are provided on the opposite inner walls of the two square cavities. Two splined sleeves 22 are rotatably mounted in each of the four rotating holes. A driving bevel gear 25 is fixedly fitted onto the outer periphery of each splined sleeve 22. A splined shaft 23 is fitted into both splined sleeves 22. The two ends of the splined shaft 23 are rotatably mounted on the opposite inner walls of the lower U-shaped plate 15 and the upper U-shaped plate 16, respectively. A drive motor 24 is fixedly mounted at the bottom of the lower U-shaped plate 15, and the output shaft of the drive motor 24 is connected to the bottom end of the splined shaft 23.

[0025] In this embodiment, the drive motor 24 drives the spline shaft 23 to rotate, which in turn drives the spline sleeve 22 to rotate via spline engagement. The driving bevel gear 25 rotates with the spline sleeve 22 and drives the driven bevel gear 26 to rotate, ultimately causing the upper and lower drive shafts 21 to rotate in opposite directions, thus enabling the feed rollers 19 to clamp and convey the aluminum profile. The meshing transmission of the bevel gears changes the direction of power transmission, ensuring that the upper and lower feed rollers 19 can generate opposite rotational directions, thereby forming a clamping force and driving force on the aluminum profile. The engagement between the spline shaft 23 and the spline sleeve 22 allows power transmission to be maintained when the U-shaped block 18 is raised and lowered, ensuring that the feed rollers 19 can still rotate synchronously after the spacing is adjusted. This ensures that power transmission is not affected during the conveying of aluminum profiles of different thicknesses, maintaining a stable feeding speed.

[0026] like Figure 5 As shown, protective gaskets 20 are provided on the outer periphery of both feed rollers 19. Specifically, the protective gaskets 20 can be made of rubber material.

[0027] In this embodiment, the protective washer 20 conforms to the surface of the aluminum profile through elastic deformation, which not only avoids surface damage caused by hard contact and protects the appearance quality of the aluminum profile, but also increases friction to ensure smooth feeding and prevent the aluminum profile from slipping during the conveying process.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
