Description

Technical Field

[0001] This utility model belongs to the field of flaw detection technology for magnesium alloy castings, and specifically relates to a tooling for flaw detection of complex magnesium alloy castings. Background Technology

[0002] Magnesium alloy complex castings have wide applications in aerospace, automotive manufacturing, and electronic communications. Their manufacturing process involves various advanced casting technologies and processes. Among these, flaw detection fixtures for complex magnesium alloy castings are specialized equipment combinations designed to detect internal or surface defects in these castings. These fixtures combine multiple advanced flaw detection technologies and structural designs to improve flaw detection efficiency and accuracy, ensuring the quality and performance of the castings.

[0003] Announcement No. "CN219201420U" discloses a flaw detection fixture for complex oil circuit castings of magnesium alloy. The fixture includes a base and a flaw detection tool. The tool comprises a support frame, a soft spring, a conformal dark bag, a drive component, a bidirectional threaded rod, two moving blocks, and two clamps. The drive component is mounted on the base. Both ends of the bidirectional threaded rod are rotatably connected to the base. The drive component is connected to the bidirectional threaded rod. The base has an open slot. The two moving blocks are respectively fitted onto the outside of the bidirectional threaded rod and threadedly engaged with it. The two clamps are fixedly connected to their respective moving blocks. The support frame is positioned above the base. The soft spring is slidably connected to and passes through the support frame. The conformal dark bag is fixedly connected to the soft spring. This structural design allows for easy control of the illumination angle of complex magnesium alloy castings, avoiding inaccurate illumination and preventing missed defects.

[0004] Although the above-mentioned utility model can easily control the radiographic angle of complex magnesium alloy castings, avoid inaccurate radiography, and prevent the omission of defects, the transmission is controlled by a bidirectional threaded rod. In long-distance heavy-load linear motion, the bidirectional threaded rod may cause machine vibration and shaking due to insufficient rigidity. Moreover, the maintenance cost of the bidirectional threaded rod is high, requiring regular lubrication and inspection, and once a fault occurs, it is difficult to repair. Utility Model Content

[0005] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a tooling for flaw detection of complex magnesium alloy castings, so as to solve the problems that when using a bidirectional threaded rod to control the transmission, the bidirectional threaded rod will cause machine vibration and shaking due to insufficient rigidity during long-distance heavy-load linear motion. Moreover, the maintenance cost of the bidirectional threaded rod is high, requiring regular lubrication and inspection, and once a fault occurs, it is difficult to repair.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A tooling for flaw detection of complex magnesium alloy castings includes a worktable, a fixed frame fixedly connected to the upper end of the worktable, an electric push rod installed at one end of the fixed frame, a lifting seat fixedly connected to the telescopic end of the electric push rod, a flaw detection probe installed at the bottom end of the lifting seat, a movable seat symmetrically slidably connected to the upper end of the worktable, a fixed plate fixedly connected to the upper end of the movable seat, clamping components symmetrically and equidistantly installed at one end of the fixed plate, and a transmission component installed inside the upper part of the worktable.

[0008] The transmission assembly includes a rack, gear, worm gear, worm shaft, support block, and handwheel. A rack is slidably connected to the upper interior of the worktable. A gear is rotatably connected to the center of the upper interior of the worktable, meshing with the rack. A worm gear is fixedly connected to the center of the bottom end of the gear. Support blocks are symmetrically fixedly connected to the upper interior of the worktable. A worm gear is rotatably connected to the opposite end of the support block, meshing with the worm shaft. A handwheel is mounted on one end of the support block, passing through the support block and fixedly connected to the worm gear. Symmetrical moving slots are formed on the upper part of the worktable. A moving block is fixedly connected to the bottom of the moving seat, slidingly connected to the moving slot. The other end of the moving block is fixedly connected to the rack. This design enables smooth, low-noise transmission while maintaining high efficiency and precision, making the transmission more stable and reliable. It can withstand high torque and is easy to maintain and adjust.

[0009] As a preferred technical solution, the upper part of the worktable is symmetrically provided with T-shaped grooves, and a T-shaped block is fixedly connected to one end of the rack. The T-shaped block and the T-shaped groove are slidably connected. The cooperation between the T-shaped block and the T-shaped groove has high precision, which can realize the precise positioning of the rack movement and ensure that the rack can move along the predetermined trajectory.

[0010] As a preferred technical solution, the clamping assembly includes clamping posts, through holes, plugs, and tension springs. One end of the fixing plate has symmetrically opened through holes, and the clamping posts are slidably connected inside the through holes. The end of the clamping posts away from the clamping end is fixedly connected to a plug. Tension springs are symmetrically and equidistantly fixedly connected to one end of the fixing plate, and the other end of the tension springs is fixedly connected to the plugs. The tension springs are sleeved on the outside of the clamping posts, which can closely fit the irregular surface of the workpiece, ensuring the stability and accuracy of the flaw detection process, improving flaw detection efficiency, and avoiding inaccurate flaw detection results caused by workpiece shaking.

[0011] As a preferred technical solution, the clamping end of the clamping column is glued with a protective pad. The surface of the protective pad is provided with anti-slip protrusions. The protective pad is made of rubber. The through holes and the clamping column are symmetrically arranged at equal distances. The clamping end of the clamping column is arc-shaped, which can effectively prevent the clamping column from directly contacting the workpiece surface and avoid scratches, indentations or other forms of surface damage during the clamping process.

[0012] As a preferred technical solution, a guide column is fixedly connected to one end of the lifting seat, and a guide groove is opened at one end of the fixed frame. A guide block is fixedly connected to the end of the guide column away from the lifting seat. The guide block and the guide groove are slidably connected. The tight cooperation between the guide block and the guide groove ensures the stability and accuracy of the flaw detection probe during the lifting process, and can effectively prevent the probe from shifting or shaking during the movement, thereby improving the accuracy and reliability of the detection.

[0013] In summary, the present invention has the following main advantages:

[0014] First, in this utility model, rotating the handwheel drives the worm gear to rotate, which in turn drives the turbine gear to rotate, thereby causing the turbine gear to rotate. Because the gear and rack mesh with each other, the gear drives the rack to move when it rotates. When the rack moves, it drives the moving seat and the fixed plate to move through the moving block, thereby controlling the fixed plate to drive the clamping assembly to move. This can achieve smooth and low-noise transmission while maintaining high efficiency and high precision, making the transmission more stable and reliable. It can withstand high torque and is easy to maintain and adjust.

[0015] Secondly, in this utility model, the aluminum-magnesium alloy casting is placed on the worktable, and then the moving seat is controlled by the transmission component to move the fixed plate. The moving plate moves the clamping column, and the clamping end of the clamping column first comes into contact with the surface of the aluminum-magnesium alloy casting. Then the clamping column moves the plug and stretches the tension spring, thereby clamping and fixing the aluminum-magnesium alloy casting. This can closely fit the irregular surface of the workpiece, ensure the stability and accuracy of the flaw detection process, improve the flaw detection efficiency, and avoid inaccurate flaw detection results caused by workpiece shaking.

[0023] The transmission assembly 15 includes a rack 151, a gear 152, a worm gear 153, a worm 154, a support block 155, and a handwheel 156. The rack 151 is mirror-slidably connected to the upper interior of the worktable 1. The gear 152 is rotatably connected to the center of the upper interior of the worktable 1, and the gear 152 meshes with the rack 151. The worm gear 153 is fixedly connected to the center of the bottom end of the gear 152. Support blocks 155 are symmetrically fixedly connected to the upper interior of the worktable 1. The worm gear 154 is rotatably connected to the opposite end of the support blocks 155, and the worm gear 154 meshes with the worm 153. A handwheel 156 is mounted on one end of the support block 155, and one end of the handwheel 156 passes through the support block 155 and is fixedly connected to the worm gear 154. The upper end of the workbench 1 is symmetrically provided with a moving groove 13. The bottom end of the moving seat 9 is fixedly connected to a moving block 14. The moving block 14 and the moving groove 13 are slidably connected. The other end of the moving block 14 is fixedly connected to the rack 151. When the handwheel 156 is turned, the handwheel 156 drives the worm gear 154 to rotate. The worm gear 154 drives the turbine 153 to rotate, thereby causing the turbine 153 to drive the gear 152 to rotate. Because the gear 152 and the rack 151 mesh with each other, when the gear 152 rotates, it drives the rack 151 to move. When the rack 151 moves, it drives the moving seat 9 and the fixed plate 10 to move through the moving block 14, thereby controlling the fixed plate 10 to drive the clamping assembly 11 to move.

[0024] refer to Figure 4The upper part of the workbench 1 is symmetrically provided with T-shaped grooves 16. One end of the rack 151 is fixedly connected to a T-shaped block 17. The T-shaped block 17 and the T-shaped groove 16 are slidably connected. When the rack 151 moves, the rack 151 drives the T-shaped block 17 to slide inside the T-shaped groove 16.

[0025] refer to Figure 2 The clamping assembly 11 includes a clamping post 111, a through hole 112, a plug 113, and a tension spring 114. The fixing plate 10 has symmetrical through holes 112 at one end, and the clamping post 111 is slidably connected inside the through hole 112. The end of the clamping post 111 away from the clamping end is fixedly connected to the plug 113. The fixing plate 10 has tension springs 114 fixedly connected symmetrically at equal distances at one end, and the other end of the tension spring 114 is fixedly connected to the plug 113. The tension spring 114 is sleeved on the outside of the clamping post 111. The aluminum-magnesium alloy casting is placed on the worktable 1, and then the moving seat 9 is controlled by the transmission assembly 15 to move the fixing plate 10. The moving plate moves the clamping post 111. The clamping end of the clamping post 111 first comes into contact with the surface of the aluminum-magnesium alloy casting, and then the clamping post 111 moves the plug 113, while the tension spring 114 is stretched, thereby clamping and fixing the aluminum-magnesium alloy casting.

[0026] refer to Figure 2 The clamping end of the clamping column 111 is glued with a protective pad 12. The surface of the protective pad 12 is provided with anti-slip protrusions. The protective pad 12 is made of rubber. The through hole 112 and the clamping column 111 are symmetrically arranged at equal distances. The clamping end of the clamping column 111 is arc-shaped. The protective pad 12 can effectively prevent the clamping column 111 from directly contacting the workpiece surface, avoiding scratches, indentations or other forms of surface damage during the clamping process.

[0027] refer to Figure 1 One end of the lifting seat 4 is fixedly connected to a guide column 6, and one end of the fixed frame 2 is provided with a guide groove 8. The end of the guide column 6 away from the lifting seat 4 is fixedly connected to a guide block 7. The guide block 7 and the guide groove 8 are slidably connected. When the electric push rod 3 is activated, the lifting seat 4 is controlled to drive the flaw detection probe 5 to descend. At the same time, the lifting seat 4 drives the guide rod 6 to rise and fall. The guide rod 6 drives the guide block 7 to slide inside the guide groove 8.

[0028] Operating principle and advantages: First, place the aluminum-magnesium alloy casting on the workbench 1, turn the handwheel 156, the handwheel 156 drives the worm gear 154 to rotate, the worm gear 154 drives the turbine gear 153 to rotate, thereby causing the turbine gear 153 to drive the gear 152 to rotate. Because the gear 152 meshes with the rack 151, the gear 152 drives the rack 151 to move when it rotates. When the rack 151 moves, it drives the moving seat 9 and the fixed plate 10 to move through the moving block 14, thereby controlling the fixed plate 10 to drive the clamping assembly 11 to move. The clamping end of the clamping column 111 first comes into contact with the surface of the aluminum-magnesium alloy casting, and then the clamping column 111 drives the plug 113 to move, while the tension spring 114 is stretched, thereby clamping and fixing the aluminum-magnesium alloy casting.
