Description

Technical Field

[0001] This utility model relates to the field of suspension equipment technology, specifically to a suspension bracket for surface treatment of aluminum products. Background Technology

[0002] In modern industrial production, aluminum products are widely used in aerospace, automotive manufacturing, and electronic equipment industries due to their lightweight, corrosion resistance, and excellent processing properties. Surface treatment processes for aluminum products, such as electroplating, anodizing, and spraying, are key steps in improving their appearance and performance. During these processes, the aluminum workpieces must be suspended in the treatment tank using a suspension frame to ensure that the workpiece surface is in full contact with the treatment liquid or medium.

[0003] Currently, most traditional suspension brackets for aluminum product surface treatment employ simple hook or frame structures, which have many limitations. For example, a workpiece suspension device with adjustable height, as disclosed in CN207483236U, includes a hollow support column and a support arm at the top of the column. A turntable is located inside the support arm, and a transmission rod coaxially connected to the turntable is vertically mounted inside the column. A first gear is horizontally mounted at the bottom of the transmission rod. A rotating rod extending into the column is located on the side wall of the column, and a second gear meshing with the first gear is vertically mounted at one end of the rotating rod inside the column. A pulley is located inside the support arm at the end furthest from the column. A suspension wire is wound around the turntable, and the free end of the wire laps on the pulley and extends out of the support arm through a through-hole at the bottom of the support arm. Equipped with a hook, the lifting rod is rotated clockwise or counterclockwise, allowing the hanging line on the turntable to be released or retrieved. This enables the hook to rise or fall, allowing the height of the hook to be controlled through mechanical transmission during use, facilitating the placement and replacement of workpieces. While the height of the workpiece can be adjusted, the fixing method of this type of suspension frame is relatively simple, usually relying on a single point or a few contact points for suspension. This makes it difficult to ensure the stability of the workpiece during processing, and it is prone to shaking, displacement, or even falling. This not only affects the uniformity of the surface treatment effect but may also cause damage to the workpiece. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a suspension bracket for surface treatment of aluminum products. The upper and lower circular structure of the I-shaped suspension plate can evenly distribute the weight of the aluminum workpiece and avoid deformation of the suspension plate. The connecting rods evenly arranged around the circumference provide multiple binding points, which can realize multi-position fixation. It can not only adapt to aluminum workpieces of different specifications, but also effectively prevent the workpiece from shaking, shifting or falling during the surface treatment process. The suspension component adopts a structure of inclined holes, rollers and U-shaped rods, and realizes quick clamping of the suspension plate through the lever principle.

[0005] A suspension bracket for surface treatment of aluminum products includes a suspension assembly that can hold a suspension plate. The suspension plate is generally I-shaped, with the upper and lower sides being disc-shaped and the middle part being a circular shaft. A set of circumferentially evenly arranged connecting rods are fixed on the upper and lower edges of the suspension plate. The connecting rods are used to bind and support the aluminum product workpiece.

[0006] Furthermore, the suspension assembly includes a suspension rod with an annular upper end and a connecting plate fixedly mounted on the lower end. The connecting plate has oblique holes at both ends, with an angle of 50-60 degrees between the oblique holes and the suspension rod. A roller passes through the oblique holes, and both ends of the roller are rotatably connected to one end of a U-shaped rod. A connecting block is rotatably connected to the lower middle part of the U-shaped rod, and the connecting block is fixedly connected to a fixing plate. A clamping block is fixedly connected to the lower end of the U-shaped rod. The clamping blocks are arranged opposite each other and are slotted. The slots of the clamping blocks match the suspension disc, and the slots of the clamping blocks can engage the upper edge of the suspension disc.

[0007] Furthermore, a locking rod is fixedly connected to the upper center of the fixing plate. The locking rod is U-shaped, and the connecting plate is slidably disposed inside the locking rod. A limit hole is opened in the lower part of the connecting plate, and a through threaded hole is opened in the upper part of the locking rod. A bolt is screwed into the threaded hole, and the bolt can pass through the limit hole.

[0008] Furthermore, a positioning hole is provided at the center of the upper side of the suspension plate, and a positioning post is fixedly connected to the center of the lower side of the fixing plate. The positioning post can be inserted into the positioning hole, and the positioning post matches the positioning hole.

[0009] Furthermore, the connecting block is tilted.

[0010] Furthermore, the angle between the opposite side of the connecting block and the axis of the suspension rod is 30 degrees.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are:

[0012] 1. The upper and lower circular structure of the I-shaped suspension plate can evenly distribute the weight of the aluminum workpiece and prevent the suspension plate from deforming. The connecting rods evenly arranged around the circumference provide multiple binding points, which can achieve multi-position fixation. It can not only adapt to aluminum workpieces of different specifications, but also effectively prevent the workpiece from shaking, shifting or falling during the surface treatment process.

[0013] 2. The suspension assembly adopts a structure of inclined holes, rollers and U-shaped rods, which realizes quick clamping of the suspension plate through the lever principle, making operation simple and greatly improving the efficiency of installation and disassembly;

[0014] 3. The cooperation between the positioning pin and the positioning hole enables precise axial and radial positioning of the suspension plate, ensuring the accuracy of the workpiece suspension position and meeting the requirements of surface treatment processes with high positional accuracy, such as electroplating and spraying; the locking method of the bolt and the limiting hole effectively prevents the clamping block from loosening.

[0015] 4. The 30-degree tilt angle design of the connecting block optimizes the force direction of the clamping block, making the clamping force more concentrated and perpendicular to the surface of the suspension plate, reducing the lateral force component, and further improving the clamping stability.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] A suspension bracket for surface treatment of aluminum products includes a suspension assembly that can hold a suspension plate 7. The suspension plate 7 is generally I-shaped, with the upper and lower sides being disc-shaped and the middle part being a circular shaft. A set of circumferentially evenly arranged connecting rods 702 are fixed on the upper and lower edges of the suspension plate 7. The connecting rods 702 are used to bind and support the aluminum product workpiece.

[0024] In this embodiment, utilizing the structural characteristics of the I-shaped suspension plate 7, the upper and lower discs provide support surfaces, the central circular shaft ensures structural stability, and the evenly distributed connecting rods 702 form binding points. The aluminum workpiece is bound by the connecting rods 702, allowing the workpiece to be suspended from the edge of the suspension plate 7. The suspension assembly achieves overall suspension. The I-shaped design balances strength and lightweight, and the upper and lower discs can evenly distribute the weight of the workpiece, preventing deformation of the suspension plate 7. The evenly distributed connecting rods 702 facilitate binding multiple workpieces, and the even arrangement prevents shaking or falling. It is suitable for aluminum workpieces of different specifications.

[0025] The suspension assembly includes a suspension rod 1, the upper end of which is annular, and a connecting plate 2 fixedly mounted on the lower end of which is connected. The connecting plate 2 has oblique holes 11 at both ends, with an angle of 50-60 degrees between the oblique holes 11 and the suspension rod 1. A roller 12 passes through the oblique holes 11, and both ends of the roller 12 are rotatably connected to one end of a U-shaped rod 3. A connecting block 4 is rotatably connected to the lower middle part of the U-shaped rod 3, and the connecting block 4 is fixedly connected to a fixing plate 6. A clamping block 5 is fixedly connected to the lower end of the U-shaped rod 3. The clamping blocks 5 are oppositely positioned and have a slotted shape. The slots of the clamping blocks 5 match the suspension disc 7, and the slots of the clamping blocks 5 can engage the upper edge of the suspension disc 7.

[0026] In this embodiment, the suspension assembly is lifted upwards by engaging the upper edge of the suspension plate 7 with the slot of the clamping block 5 of the suspension assembly. The suspension assembly is clamped by the inclined hole 11, the roller 12, and the U-shaped rod. The inclined hole 11 (50-60 degree included angle) cooperates with the roller 12. Under the limiting effect of the inclined hole 11 and the gravity of the suspension plate 7 and the workpiece, when the suspension rod 1 of the suspension assembly moves upwards under the drive of the crane, it can drive the connecting plate 2 to move. The roller 12 moves downwards within the inclined hole 11. Under the constraints of gravity and the inclined hole 11, the U-shaped rod 3 eventually rotates, forming a lever-type clamping action. When the U-shaped rod 3 drives the clamping block 5 to completely lock the upper edge of the suspension plate 7, the roller 12 is at the lowest end of the inclined hole 11. The slot of the clamping block 5 matches the upper edge of the suspension plate 7, and the slot locks the edge of the suspension plate 7 to achieve mechanical locking. The angle design of the inclined hole 11 (50-60 degrees) allows the clamping block 5 to fit against the edge of the suspension plate 7, enhancing the clamping stability and preventing the suspension plate 7 from falling off due to shaking.

[0027] The upper center of the fixing plate 6 is fixedly connected to the locking rod 10, which is U-shaped. The connecting plate 2 is slidably disposed in the locking rod 10. The lower part of the connecting plate 2 is provided with a limiting hole 13, and the upper part of the locking rod 10 is provided with a through threaded hole. The bolt 9 is screwed into the threaded hole and can pass through the limiting hole 13.

[0028] In this embodiment, the locking rod 10 is fitted onto the connecting plate 2, and the bolt 9 is used to pass through the threaded hole and the limiting hole 13 to achieve locking. The connecting plate 2 can slide inside the locking rod 10. When the clamping block 5 is completely locked onto the suspension plate 7, the limiting hole 13 and the threaded hole of the connecting plate 2 correspond. At this time, the bolt 9 can be screwed in. After the bolt 9 is tightened, the sliding of the connecting plate 2 is restricted, and the relative position of the clamping block 5 and the suspension plate 7 is fixed. This can prevent the clamping block 5 from loosening due to vibration and other factors during use, and ensure the safety and reliability of the suspension system.

[0029] The upper center of the suspension plate 7 is provided with a positioning hole 701, and the lower center of the fixing plate 6 is fixedly connected to a positioning post 8. The positioning post 8 can be inserted into the positioning hole 701, and the positioning post 8 matches the positioning hole 701. The positioning post 8 is inserted into the positioning hole 701 of the suspension plate 7, and axial positioning is achieved through the post-hole cooperation, ensuring the coaxiality of the suspension plate 7 during installation. The positioning post 8 restricts the radial displacement of the suspension plate 7, and three-dimensional fixation is achieved in cooperation with the slot of the clamping block 5, avoiding the suspension plate 7 from shifting or tilting during installation, ensuring the accuracy of the workpiece suspension position. The cooperation between the positioning post 8 and the positioning hole 701 can reduce the horizontal sway of the suspension plate 7.

[0030] The connecting block 4 is set at an angle.

[0031] The angle between the opposite side of the connecting block 4 and the axis of the suspension rod 1 is 30 degrees.

[0032] The method of using this utility model is as follows: Use a crane or similar device to suspend the upper annular ring of the suspension rod 1. Place the suspension plate 7 on the operating table. Based on the shape and size of the aluminum workpiece, use the connecting rods 702 evenly distributed around the circumference of the suspension plate 7, and use binding materials (such as ropes, clamps, etc.) to bind and fix the workpiece to the edge of the suspension plate 7 at multiple angles and positions, ensuring that the workpiece is stably suspended and will not shake or fall. Adjust the position of the suspension components so that the slot of the clamping block 5 corresponds to the upper edge of the suspension plate 7, and insert the positioning pin 8 into the positioning hole 701 at the center of the upper side of the suspension plate 7, ensuring precise fit between the two. Lift the suspension rod 1, suspend... The suspension plate 7 is held and lifted by the clamping block 5. Under the weight of the suspension plate 7 and the workpiece, the roller 12 rolls down in the inclined hole 11 to the bottom of the inclined hole 11. The U-shaped rod rotates and drives the clamping block 5 to clamp the upper edge of the suspension plate 7. The slot of the clamping block 5 firmly holds the suspension plate 7. At this time, the limiting hole 13 of the connecting plate 2 is aligned with the threaded hole. The bolt 9 is tightened to lock the connecting plate 2 and the locking rod 10. The suspension assembly is pulled up to adjust the suspension plate 7 to a suitable suspension height. The suspension frame with the workpiece installed is hoisted as a whole into the surface treatment equipment (such as the treatment tank) and the aluminum product surface treatment operation is carried out according to the established surface treatment process.

[0033] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
