[0026] like Figure 1 As shown:

[0027] A highly mobile parallel robot platform for sandblasting machines includes two sets of parallel support frames 1 and a sandblasting machine body 2 disposed between the two sets of support frames 1.

[0028] like Figures 1-6 As shown:

[0029] In conjunction with the above, in order to form an effective dust barrier for the working area of ​​the sandblasting machine body 2, a dust-proof assembly 3 is also provided on the outside of the sandblasting machine body 2.

[0030] A fixed base 31 is provided on the top of the sandblasting machine body 2. A fixed plate 32 is fixed between the fixed base 31 and the sandblasting machine body 2. A drive motor 34 is screwed to the middle of the lower surface of the fixed base 31. A drive gear 33 is fixed to the output end of the drive motor 34. Driven gears 35 are meshed at the four corners of the surface of the drive gear 33. A driven shaft 36 is fixed inside the driven gear 35. The driven shaft 36 is rotatably connected between the fixed base 31 and the fixed plate 32. A transmission belt 37 is connected to the surface of the driven shaft 36 through a pulley. A transmission shaft 38 is connected to the end of the transmission belt 37 away from the driven shaft 36 through a pulley. A bevel gear pair 39 is fixed to the surface of the transmission shaft 38. The transmission shaft 38 is rotatably connected to the bottom of the fixed base 31. A tilting shaft 310 is coaxially fixed inside the bevel gear of the bevel gear pair 39. The tilting shaft 310 is rotatably connected to the surface of the fixed plate 32. A dust cover plate 311 is fixed to the surface of the tilting shaft 310.

[0031] In conjunction with the above, in order to enable the sandblasting machine body 2 to move flexibly to different positions in the plane, a moving component 4 is also included, which is installed between the support frame 1 and the sandblasting machine body 2. The moving component 4 includes a moving crossbeam 41, a transverse rack 42, a transverse gear 43, a transverse motor 44, a transverse guide rail 45, a longitudinal crossbeam 46, a longitudinal rack 47, a longitudinal gear 48, a longitudinal motor 49, a moving base 410, a longitudinal guide rail 411, and a robot arm 412.

[0032] A movable crossbeam 41 is fixed to the surface of the support frame 1. A transverse rack 42 is fixed to the surface of each of the two sets of movable crossbeams 41. A transverse gear 43 is meshed with the surface of the transverse rack 42. A transverse guide rail 45 is fixed to the surface of each of the two sets of movable crossbeams 41, and a longitudinal crossbeam 46 is slidably connected between the two sets of transverse guide rails 45. A transverse motor 44 is screwed to both sides of the surface of the longitudinal crossbeam 46, and the output end of the transverse motor 44 is fixedly connected to the surface of the transverse gear 43. The surface of the longitudinal crossbeam 46 is fixed... A longitudinal rack 47 is fixed, and a longitudinal gear 48 is meshed on the surface of the longitudinal rack 47. Two sets of longitudinal guide rails 411 are fixed on the surface of the longitudinal beam 46. A movable seat 410 is slidably connected between the two sets of longitudinal guide rails 411. A longitudinal motor 49 is screwed to the surface of the movable seat 410, and the output end of the longitudinal motor 49 is fixedly connected to the surface of the longitudinal gear 48. A robot arm 412 is fixed to the surface of the movable seat 410, and the output end of the robot arm 412 is fixedly connected to the fixed seat 31.

[0033] The working principle and usage process of this utility model are as follows: First, the transverse motor 44 is started, driving the transverse gear 43 to rotate. The transverse gear 43 meshes with the transverse rack 42. Due to the meshing transmission principle of the rack and gear, the rotational motion of the transverse gear 43 is converted into the transverse linear motion of the longitudinal beam 46 along the transverse guide rail 45. The two sets of transverse guide rails 45 provide stable support and precise guidance for the longitudinal beam 46, ensuring smooth and accurate transverse movement. This allows for the adjustment of the transverse position of the sandblasting machine body 2 in the horizontal direction to adapt to the sandblasting requirements of workpieces in different positions. Then, the longitudinal motor 49 is started, driving the longitudinal gear 48 to rotate. The longitudinal gear 48 meshes with the longitudinal rack 47, causing the moving seat 410 to move longitudinally along the longitudinal guide rail 411. The longitudinal guide rail 411 provides precise guidance and support for the moving seat 410, ensuring its stability and accuracy during longitudinal movement. The forward and reverse rotation and speed control of the longitudinal motor 49 can precisely adjust the position of the sandblasting machine body 2 in the longitudinal direction. This, combined with the lateral movement, allows the sandblasting machine body 2 to flexibly move to different positions within a plane. The robotic arm 412 on the moving base 410 is connected to the fixed base 31, ultimately driving the sandblasting machine body 2 to achieve precise multi-degree-of-freedom position adjustment. This greatly expands the platform's applicability and enhances its practicality in complex production environments, meeting diverse sandblasting needs and improving the mobility and accuracy of sandblasting operations. It ensures that in complex sandblasting operations, the sandblasting machine body 2 can accurately align with various parts of the workpiece, significantly improving work efficiency and finished product quality. It reduces rework and material waste caused by inaccurate positioning. This not only enhances the sandblasting capabilities for conventional flat and simple curved surfaces but also provides possibilities for sandblasting processes on complex-shaped workpieces, expanding the application range of sandblasting technology and meeting the high-precision, complex process requirements of high-end manufacturing.

[0034] It is worth noting that the robotic arm 412 can drive the sandblasting machine body 2 to any target position within the working area, and can flexibly adjust the posture and angle of the sandblasting machine body 2 according to the preset program and process requirements to ensure the efficiency, accuracy and consistency of sandblasting operations. At the same time, it also improves the mobility and adaptability of the entire platform, enabling it to handle workpiece processing tasks of various shapes, sizes and sandblasting process requirements.

[0035] Furthermore, when the dust-shielding function needs to be activated, the drive motor 34 is started, and its output end drives the drive gear 33 to rotate. The four corners of the drive gear 33 are meshed with the driven gears 35. Due to the meshing transmission characteristics of the gears, the rotational motion of the drive gear 33 is transmitted to the four driven gears 35, causing the driven gears 35 to rotate synchronously around their respective fixed driven shafts 36. With the cooperation of the transmission belt 37, this drives the transmission shaft 38 to rotate, realizing the transmission of power. This, in turn, drives the bevel gear pair 39 to rotate, thereby causing the tilting shaft 310 to rotate on the surface of the fixed plate 32. This allows the dust-shielding plate 311 to smoothly tilt, ensuring dust-shielding operation during the operation of the sandblasting machine body 2. The dust shield 311 can be deployed quickly and stably to form an effective dust barrier over the working area of ​​the sandblasting machine body 2, greatly reducing the flying and spreading of dust during the sandblasting process. This not only effectively protects the health of operators from the harm of inhaling dust particles and reduces the risk of respiratory diseases, but also significantly improves the air quality and visibility in the workplace, providing a clean environment for the normal operation of other equipment. It also reduces the corrosion and damage of dust to surrounding electrical equipment, precision instruments, etc., reduces the incidence of equipment failure, and extends the service life of equipment, thereby improving the safety and stability of the entire working area and helping to improve production efficiency and ensure the continuity of production.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
