Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum rod production technology, specifically to a clamping device for aluminum rod flaw detection. Background Technology
[0002] After aluminum bars are produced, they generally need to undergo flaw detection before leaving the factory to check for internal problems. During flaw detection, the aluminum bars need to be moved onto the flaw detection device. After the flaw detection is completed, the aluminum bars are moved to the set position. This process requires the cooperation of a clamping device to improve the efficiency of flaw detection.
[0003] Existing gripping devices for aluminum rod flaw detection typically use two sets of jaws to clamp the aluminum rod. However, the inner diameter of the jaws is fixed when they are closed. When gripping aluminum rods of different diameters, rods smaller than the inner diameter of the jaws may wobble during movement after gripping because the jaws cannot fit properly, resulting in poor positioning and damage to the aluminum rod surface. Furthermore, the gripping device can usually only move horizontally, requiring the aluminum rod to be positioned in the same direction as the device to ensure successful gripping. When the aluminum rod is placed in different directions, workers need to move it to adjust its position, increasing the labor intensity of workers, prolonging the gripping time, and reducing the efficiency of subsequent flaw detection. Utility Model Content
[0004] The purpose of this invention is to provide a clamping device for aluminum rod flaw detection, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for aluminum rod flaw detection, comprising:
[0006] The frame has two sets of movable components on its inner side and a movable frame on the outer side of the movable components. A hydraulic cylinder is fixedly connected to the top of the movable frame, and a connecting frame is fixedly connected to the piston rod of the hydraulic cylinder. A mounting plate is provided below the connecting frame.
[0007] Position sensors are installed on the outside of the mounting plate, and there are multiple of them. A controller is installed on the outside of the frame.
[0008] A drive assembly is located at the bottom of the mounting plate. Two sets of transmission assemblies are symmetrically arranged on the outer side of the drive assembly. A clamping assembly is provided on the outer side of each set of transmission assemblies. A connecting groove is provided on the inner side of the clamping assembly.
[0009] A cylinder is fixed to the bottom of the mounting plate, and a rotating assembly is provided at one end of the cylinder piston rod;
[0010] A guide assembly is disposed on the outside of the rotating assembly, and a connecting shaft is disposed on the inside of the rotating assembly. One end of the connecting shaft is rotatably connected to the bottom of the connecting frame, and a limit assembly is disposed on the top of the mounting plate.
[0011] Preferably, the drive assembly includes a motor fixed to the outside of the mounting plate, and the output end of the motor is provided with a worm gear.
[0012] Preferably, the transmission assembly includes a connecting seat fixed to the bottom of the mounting plate, a worm gear rotatably connected to the inner side of the connecting seat, and the outer side of the worm meshing with the outer side of the worm gear.
[0013] Preferably, the gripping assembly includes a first gripper fixed to the outside of one set of worm gears, and a second gripper fixedly connected to the outside of the other set of worm gears, wherein a connecting groove is provided on the inner side of the second gripper.
[0014] Preferably, the rotating assembly includes a toothed plate fixed to the cylinder piston rod, a gear meshing with the outer side of the toothed plate, and the inner wall of the gear being fixedly connected to the outer side of the connecting shaft.
[0015] Preferably, the guide assembly includes a slider fixed to the outside of the toothed plate, a guide rail fixedly connected to the bottom of the mounting plate, and the outside of the slider slidably connected to the outside of the guide rail.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention, through the design of the connecting groove, allows the first gripper to form a cross posture with the second gripper during the closing process, until the aluminum rod is tightly clamped against its outer side, enabling the gripping of aluminum rods of different diameters. This prevents the aluminum rod from wobbling during movement, reducing the risk of damage. Furthermore, the gears are driven to rotate during the movement of the toothed plate, and the connecting shaft transmits kinetic energy, causing the mounting plate to rotate along the bottom of the connecting frame. This allows the gripping assembly to adjust its direction without worker intervention, achieving autonomous adjustment of the device, reducing worker labor intensity, and shortening gripping time.

Detailed Implementation
[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0025] Please see Figure 1-4 As shown, a clamping device for aluminum rod flaw detection includes a frame 1. Two sets of moving components 2, each consisting of a motor and a screw, are arranged inside the frame 1. When the motor drives the screw to rotate, it causes a moving frame 3, threadedly connected to the screw, to move parallel, thereby achieving lateral movement adjustment of the device. A moving frame 3 is arranged outside the moving components 2. A hydraulic cylinder 4 is fixedly connected to the top of the moving frame 3, responsible for vertical movement adjustment of the device. A connecting frame 5 is fixedly connected to the piston rod of the hydraulic cylinder 4, and a mounting plate 6 is arranged below the connecting frame 5. Multiple position sensors 7 are arranged outside the mounting plate 6. A controller 8 is arranged outside the frame 1 and is electrically connected to the position sensors 7. A drive assembly 9 is located at the bottom of the mounting plate 6. Two sets of transmission assemblies 10 are symmetrically arranged outside the drive assembly 9. Clamping components 11 are arranged outside each of the two sets of transmission assemblies 10, and connecting grooves 12 are provided inside the clamping components 11.
[0026] Cylinder 13 is fixed to the bottom of mounting plate 6. One end of the piston rod of cylinder 13 is provided with a rotating component 14. Guide component 15 is provided on the outside of rotating component 14. A connecting shaft 16 is provided on the inside of rotating component 14. When the connecting shaft 16 rotates, it will drive mounting plate 6 to rotate along the bottom of connecting frame 5. One end of connecting shaft 16 is rotatably connected to the bottom of connecting frame 5. A limit component 17 is provided on the top of mounting plate 6.
[0027] The drive assembly 9 includes a motor 91 fixed to the outside of the mounting plate 6. The output end of the motor 91 is provided with a worm gear 92. The motor 91 is powered by an external power supply and can drive the worm gear 92 to rotate.
[0028] The transmission assembly 10 includes a connecting seat 101 fixed to the bottom of the mounting plate 6. A worm gear 102 is rotatably connected to the inner side of the connecting seat 101. The outer side of the worm 92 is meshed with the outer side of the worm gear 102. The worm 92 drives the worm gear 102 to rotate. The connecting seat 101 improves the stability of the worm gear 102 when it rotates.
[0029] The gripping assembly 11 includes a first gripper 111 fixed to the outside of one set of worm gears 102, and a second gripper 112 fixedly connected to the outside of the other set of worm gears 102. A connecting groove 12 is provided on the inner side of the second gripper 112. The first gripper 111 and the second gripper 112 clamp and release the aluminum rod by closing or opening. The connecting groove 12 allows the first gripper 111 and the second gripper 112 to close at a smaller closing angle by crossing, thereby improving the stability of gripping small-diameter aluminum rods.
[0030] The rotating assembly 14 includes a gear plate 141 fixed to the piston rod of the cylinder 13. A gear 142 is meshed with the outer side of the gear plate 141. The inner wall of the gear 142 is fixedly connected to the outer side of the connecting shaft 16. The outer side of the connecting shaft 16 is fixedly connected to the inner wall of the mounting plate 6. When the gear plate 141 moves, it drives the gear 142 to rotate the connecting shaft 16 accordingly.
[0031] The guide assembly 15 includes a slider 151 fixed to the outside of the toothed plate 141. A guide rail 152 is fixedly connected to the bottom of the mounting plate 6. The outside of the slider 151 is slidably connected to the outside of the guide rail 152. When the toothed plate 141 moves, it will drive the slider 151 to slide along the inside of the guide rail 152. The guide rail 152 restricts the movement path of the slider 151, so that the toothed plate 141 can move in a parallel direction.
[0032] The limiting component 17 includes a limiting groove 171 formed on the top of the mounting plate 6. Four sets of guide blocks 172 are fixedly connected to the bottom of the connecting frame 5. The outer sides of the four sets of guide blocks 172 are slidably connected to the inner side of the limiting groove 171. A circular limiting block is fixed to one end of the guide block 172 to enhance the stability of its connection with the limiting groove 171 and prevent it from detaching from the inner side of the limiting groove 171. When the mounting plate 6 rotates, the limiting groove 171 will rotate along the outer side of the four sets of guide blocks 172, ensuring that the mounting plate 6 can rotate according to a predetermined trajectory.
[0033] Working principle: During use, when it is necessary to clamp the aluminum rod, the moving component 2 first drives the moving frame 3 to move above the aluminum rod. Then, the piston rod of the hydraulic cylinder 4 extends, driving the connecting frame 5 and the mounting plate 6 to move downward as a whole. The position sensor 7 transmits the position information of the clamping component 11 to the controller 8 in real time. The controller 8 uses this information to determine whether the clamping component 11 has reached the designated position. Then, the motor 91 starts, driving the worm gear 92 to rotate, and at the same time, the two sets of worm wheels 102 rotate in opposite directions around the connecting seat 101. The first gripper 111, which is connected to the two sets of worm wheels 102 respectively, moves downward. The first gripper 111 and the second gripper 112 then close together. Due to the setting of the connecting groove 12, the first gripper 111 can form a cross posture with the second gripper 112 during the closing process until the aluminum rod is clamped, realizing the clamping of aluminum rods of different diameters. When it is necessary to adjust the direction of the clamping component 11, the cylinder 13 is started first, its piston rod retracts, driving the toothed plate 141 to move backward. The gear 142 is driven to complete the corresponding rotation during the movement of the toothed plate 141. The connecting shaft 16 will transmit kinetic energy, causing the mounting plate 6 to rotate along the bottom of the connecting frame 5, and then the clamping component 11 completes the direction adjustment.
