Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting machines, in particular to a multi-station intermittent wet sandblasting machine. Background Art

[0002] During the production process, engine turbine blades require sandblasting. Traditionally, dry manual sandblasting machines or automatic sandblasting machines are used. One or two swing arms are placed in the work cabin, and multiple sandblasting guns are placed on each swing arm. During sandblasting, the sandblasting guns swing back and forth at an angle to perform the sandblasting process on the engine turbine blades.

[0003] However, in the actual operation of the above method, since the sandblasting gun needs to swing back and forth at an angle during sandblasting, the spraying distance of the sandblasting gun changes continuously, problems such as uneven surface of the product after sandblasting, uneven internal stress distribution, uneven surface texture after sandblasting, and easy generation of S-shaped yin and yang patterns will occur. As a result, the product will be scrapped after sandblasting or require multiple sandblasting, affecting production capacity. In addition, the arrangement of multiple swing arms also increases the difficulty of adjusting the sandblasting gun, especially the sandblasting gun in the center is blocked by the sandblasting gun at the near end, making adjustment very inconvenient. At the same time, dry sandblasting causes large dust pollution, which affects the health of the operator and pollutes the working environment of the workshop. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-2As shown, the present invention provides a multi-station intermittent wet sandblasting machine, comprising a driving mechanism, a lifting mechanism 14, a mounting assembly, and at least two sandblasting guns 12. In this embodiment, a total of eight sandblasting guns 12 are provided. The sandblasting guns 12 are all mounted on the mounting assembly. The lifting mechanism 14 is connected to the mounting assembly, and the driving mechanism is connected to the lifting mechanism 14 to drive the mounting assembly and the sandblasting guns 12 to move up and down.

[0023] The lifting mechanism 14 includes a mechanism mounting box 13 and a ball screw, a screw nut, a lifting guide rail and a lifting slider installed inside the mechanism mounting box 13. The lifting slider slides with the lifting guide rail, the screw nut is threaded with the ball screw, and the lifting slider is connected to the screw nut. The driving mechanism drives the ball screw to rotate, and causes the screw nut to drive the lifting slider to move. The installation assembly includes a lifting seat 3, a vertical rod 4 and a cross bar 11. The vertical rod 4 is mounted on the lifting seat 3, and the cross bar 11 is mounted on the vertical rod 4. The sandblasting gun 12 is mounted on the cross bar 11. The lifting seat 3 is connected to the lifting slider, and causes the lifting slider to drive the sandblasting gun 12 to move. The driving mechanism includes a servo motor 1 and a planetary reducer 2. The output shaft of the servo motor 1 is connected to the planetary reducer 2. The planetary reducer 2 is connected to the ball screw through a coupling. The planetary reducer motor converts the high-speed and low-torque output of the servo motor 1 into low-speed and high-torque through its internal planetary gear system. The output end is tightly connected to the ball screw through a coupling. The coupling ensures the coaxiality and torque transmission stability of the two during rotation. The ball screw and the screw nut cooperate with each other through precise threads, which converts the rotational motion of the ball screw into the linear motion of the screw nut. When the ball screw rotates, the screw nut moves along the axial direction of the ball screw, and with the linear movement of the screw nut, the lifting slider also slides smoothly along the lifting guide rail. Therefore, when the servo motor 1 starts to run, through the coordinated action of the planetary reduction motor, ball screw and other transmission components, the vertical rod 4 drives the cross rod 11 and the sandblasting gun 12 to slowly descend. The sandblasting gun 12 performs uniform sandblasting on the product during the descent process. When the sandblasting gun 12 descends to the set lowest position and completes the sandblasting operation, the servo motor 1 reverses and accelerates, and quickly drives the vertical rod 4 and the cross rod 11 to rise and reset to the initial position through the same transmission path, ready for the next sandblasting operation.

[0024] It also includes a mounting plate 5, a bearing sleeve 6 and a telescopic protective cover 7. The mechanism mounting box 13 is mounted on the mounting plate 5. The bearing sleeve 6 is arranged on one side of the mounting plate 5. The vertical rod 4 and the bearing sleeve 6 are slidably matched. The telescopic protective cover 7 is sleeved on the outside of the vertical rod 4. The telescopic protective cover 7 maintains a sealed structure at the junction with the inner wall of the cleaning chamber to prevent the leakage of abrasives and dust.

[0025] The middle part of the cross bar 11 is equipped with a first connecting sleeve 10 and a first locking bolt. The cross bar 11 is slidably connected to the vertical bar 4 through the first connecting sleeve 10. The first locking bolt passes through the first connecting sleeve 10 and is threadedly connected to the vertical bar 4, so that the cross bar 11 is fixed to the vertical bar 4. The first connecting sleeve 10 is used to adjust the longitudinal height position of the cross bar 11. The cross bar 11 is equipped with at least two mounting brackets 9 for mounting the sandblasting gun 12. The middle part of the mounting bracket 9 is equipped with a second connecting sleeve 8 and a second locking bolt. The mounting bracket 9 is slidably connected to the cross bar 11 through the second connecting sleeve 8. The second locking bolt passes through the second connecting sleeve 8 and is threadedly connected to the cross bar 11, so that the mounting bracket 9 is fixed to the cross bar 11. The second connecting sleeve 8 is used to adjust the horizontal position of the mounting bracket 9. One side of the mounting bracket 9 is equipped with a telescopic rod 15 and The third locking bolt 16, the telescopic rod 15 and the mounting bracket 9 are slidably matched to adjust the horizontal distance between the sandblasting gun 12 and the product. The third locking bolt 16 passes through the telescopic rod 15 and is threadedly connected to the mounting bracket 9. One side of the telescopic rod 15 is equipped with a rotating rod 17 and a fourth locking bolt 18. The rotating rod 17 rotates with the telescopic rod 15 to adjust the angle between the sandblasting gun 12 and the mounting bracket 9. The fourth locking bolt 18 passes through the rotating rod 17 and is threadedly connected to the telescopic rod 15. The front end of the rotating rod is equipped with an angle adjustment plate 19. The sandblasting gun 12 is set on the angle adjustment plate 19, and the angle adjustment plate 19 is provided with an adjustment slot 20 for adjusting the horizontal angle of the sandblasting gun 12. The adjustment slot 20 is arc-shaped, which can adjust parameters such as the position and angle of the sandblasting gun 12, thereby improving the sandblasting effect.

[0026] Compared with traditional technology: when the servo motor 1 starts to run, through the coordinated action of transmission components such as the planetary reduction motor and the ball screw, the vertical rod 4 drives the horizontal rod 11 and the sandblasting gun 12 to slowly descend, and the sandblasting gun 12 performs uniform sandblasting on the product during the descending process. When the sandblasting gun 12 descends to the set lowest position and completes the sandblasting operation, the servo motor 1 reverses and accelerates, and quickly drives the vertical rod 4 and the horizontal rod 11 to rise and reset to the initial position through the same transmission path, preparing for the next sandblasting operation. During sandblasting, the sandblasting gun 12 moves up and down, and the spraying distance between the sandblasting gun 12 and the product remains unchanged. After sandblasting, the surface of the product is smooth, the internal stress is evenly distributed, and the surface texture after sandblasting is uniform, and no S-shaped yin and yang patterns are produced. In addition, a wet automatic sandblasting machine is used to sandblast the engine turbine blades, without dust pollution, and has little impact on the operator's health and the workshop working environment. At the same time, since only one horizontal rod 11 is provided, the distance and angle of the sandblasting gun 12 are easy to adjust.
