Description

Technical Field

[0001] This utility model belongs to the field of surface treatment technology, and more specifically, it relates to a sandblasting robot with multi-axis adjustment. Background Technology

[0002] A sandblasting machine is a mechanical device used for surface treatment of workpieces. It removes impurities and rust from the workpiece surface by blasting sand particles, or roughens the surface. In actual sandblasting operations, the blasting head of a traditional sandblasting machine has limitations. When dealing with complex-shaped parts, the limited mobility of the blasting head prevents it from flexibly blasting from various angles, resulting in a limited blasting range. This makes it difficult to effectively treat certain areas of the part, reducing the cleanliness, roughness, and other quality indicators of the workpiece surface. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a multi-axis adjustable sandblasting robot, which solves the problem that existing sandblasting mechanisms are not precise enough in position adjustment and not flexible enough in angle adjustment, thus reducing their practicality.

[0004] This utility model provides a sandblasting robot with multi-axis adjustment, achieved through the following specific technical means:

[0005] A multi-axis adjustable sandblasting robot includes a sandblasting chamber and a robot body. The sandblasting chamber has a folding door on one side, and a truss-like inverted device is installed on the top of the chamber. A dust removal system is installed outside the sandblasting chamber, with its suction pipes connected to the chamber. A workpiece passage extends outward from the sandblasting chamber through the open folding door, and a flatcar runs on the workpiece passage. Two sets of motion trusses are constructed inside the sandblasting chamber. Each motion truss includes two truss columns, and a truss overhead track beam is erected and fixed on top of the two columns. The robot body is suspended from the motion trusses. The robot body includes a main beam with travel points at both ends. The mechanism includes a trolley frame with two rows of wheels at its bottom, which roll on the truss overhead rail beam. A vertical hydraulic telescopic rod is installed in the middle section of the main beam via a fixed plate. The piston rod of the hydraulic telescopic rod is located at its lower end, and a first connecting plate is fixedly connected to the end of the piston rod. A servo motor is bolted to the lower part of the first connecting plate, with its output end facing vertically downward. A movable arm is fixedly connected to the output end, and the movable arm includes a second connecting plate. A fixed frame is hinged to the second connecting plate via two sets of side support plates. Two spray guns are installed on the fixed frame, and the inlets of the spray guns are connected to a conveying pipe.

[0006] Furthermore, a stepper motor is mounted on the main beam via a motor mount. The output end of the stepper motor passes through one of the side walls of the trolley frame and is provided with a first bevel gear at the end. A second bevel gear meshes with one side of the first bevel gear. A rotating rod passes through the center of the second bevel gear, and the two ends of the rotating rod are rotatably connected to the trolley frame.

[0007] Furthermore, a circular gear is provided on the rotating rod; a rack is provided on the inner wall of the sandblasting chamber, the rack being parallel to the truss overhead beam of the moving truss, and the rack meshing with the circular gear.

[0008] Furthermore, the housing of the hydraulic telescopic rod has four vertical guide holes; four vertical guide posts are fixedly connected to the first connecting plate, and the guide posts slide through the guide holes respectively.

[0009] Furthermore, a first rotating support is provided on the fixed frame; a second rotating support is provided on the second connecting plate, and an electric telescopic rod is connected between the second rotating support and the first rotating support.

[0010] Furthermore, an observation window is provided on one side of the sandblasting chamber, and a control cabinet is installed on the outer wall of the sandblasting chamber near the observation window.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model, by setting a stepper motor and a walking mechanism, allows the operator to control the stepper motor. The rotation of the rotating rod is achieved through the cooperation of the first and second bevel gears, and the synchronous rotation of the spherical gears, in conjunction with the rack, allows the robot body to move horizontally on the truss overhead beam via the walking mechanism. This provides an effective adjustment function for the horizontal spraying position of the spray gun, making sandblasting more convenient and improving the sandblasting effect and efficiency.

[0013] 2. By incorporating a hydraulic telescopic rod, a servo motor, and an electric telescopic rod, this utility model allows operators to significantly adjust the vertical spraying position of the spray gun using the hydraulic telescopic rod; the servo motor allows for flexible adjustment of the axial angle of the movable arm; and the electric telescopic rod pulls the fixed frame, causing the fixed frame to rotate around the side support plate, thus flexibly adjusting the vertical spraying angle of the spray gun. This further enhances the multi-directional sandblasting effect, reduces manual operation, and improves overall sandblasting efficiency. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] This utility model provides a multi-axis adjustable sandblasting robot, including a sandblasting chamber 1 and a robot body. A folding door 2 is provided on one side of the sandblasting chamber 1, and a truss inverted device 3 is arranged on the top of the sandblasting chamber 1. A dust removal system 4 is installed outside the sandblasting chamber 1, and the dust collection pipe of the dust removal system 4 is connected to the sandblasting chamber 1. A workpiece channel 5 extends outward from the sandblasting chamber 1 through the open folding door 2, and a flatcar 6 runs on the workpiece channel 5. Two sets of motion trusses are constructed inside the sandblasting chamber 1. The motion trusses include two truss columns 7, and a truss overhead rail beam 8 is erected and fixed on the top of the two truss columns 7. The robot body is suspended on the motion trusses. The robot body includes a main beam 10, with walking mechanisms at both ends of the main beam 10. The structure includes a trolley frame 9, with two rows of traveling wheels 11 at the bottom of the trolley frame 9. The traveling wheels 11 are connected to the truss overhead rail beam 8 by rolling. A vertical hydraulic telescopic rod 18 is installed in the middle section of the main beam 10 through a fixed plate. The piston rod of the hydraulic telescopic rod 18 is located at its lower end. The end of the piston rod is fixedly connected to a first connecting plate 19. A servo motor 21 is bolted to the bottom of the first connecting plate 19. The output end of the servo motor 21 is vertically downward. A movable arm is fixedly connected to the output end. The movable arm includes a second connecting plate 22. A fixed frame 24 is hinged to the second connecting plate 22 through two sets of side support plates 23. Two spray guns 25 are installed on the fixed frame 24. The feed inlet of the spray gun 25 is connected to a feed pipe 26.

[0026] Among them, such as Figure 4 As shown, a stepper motor 13 is mounted on the main beam 10 via a motor mount. The output end of the stepper motor 13 passes through the side wall of one of the trolley frames 9 and has a first bevel gear 14 at its end. A second bevel gear 15 meshes with one side of the first bevel gear 14. A rotating rod 16 passes through the center of the second bevel gear 15, and the two ends of the rotating rod 16 are rotatably connected to the trolley frame 9. A spur gear 17 is mounted on the rotating rod 16. A rack 12 is mounted on the inner wall of the sandblasting chamber 1. The rack 12 is parallel to the truss overhead beam 8 of the moving truss and meshes with the spur gear 17. When sandblasting the workpiece, if it is necessary to make a large adjustment to the horizontal position of the spray gun 25 to adapt to the sandblasting angle, the operator can start the stepper motor 13. The rotation of the rotating rod 16 is achieved through the cooperation of the first bevel gear 14 and the second bevel gear 15. The spur gear 17 rotates synchronously and cooperates with the rack 12. The robot body moves horizontally on the truss overhead beam 8 through the walking mechanism.

[0027] Among them, such as Figure 5As shown, the housing of the hydraulic telescopic rod 18 has four vertical guide holes; four vertical guide posts 20 are fixedly connected to the first connecting plate 19, and the guide posts 20 slide through the guide holes respectively; if a large adjustment of the vertical position of the spray gun 25 is required, the operator can adjust it by extending or shortening the hydraulic telescopic rod 18; the axial angle of the movable arm can be flexibly adjusted by the servo motor 21, and the servo motor 21 and the movable arm itself have a large weight. During the rotation of the movable arm, the guide holes on the housing of the hydraulic telescopic rod 18 position the guide posts 20 to prevent the servo motor 21 and the movable arm from shaking significantly.

[0028] Among them, such as Figure 6 As shown, a first rotating support 27 is provided on the fixed frame 24; a second rotating support 28 is provided on the second connecting plate 22, and an electric telescopic rod 29 is connected between the second rotating support 28 and the first rotating support 27; the fixed frame 24 rotates around the side support plate 23 by the traction of the electric telescopic rod 29, so as to flexibly adjust the vertical spray angle of the spray gun 25.

[0029] Among them, such as Figure 1 As shown, an observation window 30 is provided on one side of the sandblasting chamber 1, and a control cabinet 31 is provided on the outer wall of the sandblasting chamber 1 near the observation window 30. The operator can obtain most of the field of vision inside the sandblasting chamber 1 through the observation window 30 from the outside of the sandblasting chamber 1, and operate the control cabinet 31 to adjust the position and angle of the spray gun 25.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In this invention, the workpiece enters the sandblasting chamber 1 from the flatcar 6 along the workpiece channel 5, reaching the position below the hydraulic telescopic rod 18. The operator, outside the sandblasting chamber 1, operates the control cabinet 31 and simulates the sandblasting action through the observation window 30. The robot synchronously scales up and down proportionally to complete the actual sandblasting work, continuously adjusting the position and angle of the robot's spray gun 25 along the sandblasting surface. The entire set of actions is stored as a program that can be called up at any time, achieving the goal of replicating the robot's actions without programming. When simulating sandblasting the workpiece, to adapt to the sandblasting angle, if a significant adjustment of the horizontal position of the spray gun 25 is required, the operator can activate the control cabinet. The stepper motor 13 rotates the rotating rod 16 through the cooperation of the first bevel gear 14 and the second bevel gear 15. The spherical gear 17 rotates synchronously and cooperates with the rack 12. The robot body moves horizontally on the truss overhead beam 8 through the walking mechanism. If a large adjustment of the vertical position of the spray gun 25 is required, the operator can adjust it by extending or shortening the hydraulic telescopic rod 18. The axial angle of the movable arm can be flexibly adjusted by the servo motor 21. The fixed frame 24 is pulled by the electric telescopic rod 29, and the fixed frame 24 rotates around the side support plate 23, flexibly adjusting the vertical spray angle of the spray gun 25.
