Description

Technical Field

[0001] The present invention relates to the technical field of automation equipment, in particular to a large-scale intelligent mobile polishing equipment. Background Art

[0002] As a major equipment manufacturing country, my country has made significant progress in manufacturing technology and has entered the field of large- and medium-sized equipment such as large-scale manufacturing of commercial aircraft, high-speed rail trains, ships and wind power generation. These equipment are of various types and have complex outer contours, especially a wide variety of large and medium-sized thin-walled cylindrical parts, which require surface grinding, polishing and painting during their manufacturing and maintenance. However, most of these processes currently still rely on workers holding grinders for manual work, which is not only inefficient, but also the dust generated during the grinding process poses a serious threat to the health of workers, and also affects the quality of grinding and polishing.

[0003] In response to the above problems, existing inventions such as CN108356656A have proposed a pneumatic robot arm and a self-dust-absorbing grinding and polishing system device using the robot arm. The device can be operated by a single person and can continuously complete the grinding and polishing process of various shapes and continuous curved parts of the equipment. It has a simple structure and does not require programming, thereby improving production efficiency and grinding and polishing surface quality, and minimizing environmental pollution and harm to workers' health. However, the device completely relies on the operator to control the surface contact pressure of the grinding and polishing machine, and cannot perform flexible grinding and polishing. Therefore, when grinding thin-walled cylinders or special-shaped parts, it is difficult to avoid deformation of the surface due to collision, and it is difficult to ensure the uniformity and smoothness of the surface after grinding and polishing. Summary of the invention

[0004] In order to overcome the problems existing in the prior art, the purpose of the present invention is to provide a large-scale intelligent mobile grinding equipment.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a large-scale intelligent mobile grinding device, comprising:

[0010] Main working principle: The base trolley is the mobile foundation of the entire equipment, responsible for moving on the horizontal plane so as to accurately move the entire grinding equipment to the vicinity of the workpiece to be polished. The base trolley may adopt a wheeled, crawler or other structure suitable for movement, and realize forward, backward, left turn, right turn and other movements through motor or hydraulic drive or direct manual push. The stand is vertically installed on the base trolley to support and fix the vertical slide structure. The stand has sufficient rigidity and stability to ensure that there is no shaking or tilting during the grinding process. The vertical slide structure is movably connected to the stand to achieve up and down movement. This lifting function enables the grinding and polishing structure to accurately position and adjust the workpiece in the vertical direction; one end of the telescopic horizontal structure is fixedly connected to the vertical slide structure, and the other end is connected to the grinding and polishing structure. Through the internal transmission mechanism, the telescopic horizontal structure can be telescoped and fine-tuned in the horizontal direction to adapt to workpieces of different sizes and shapes.

The fixed end of the swing assembly is connected to the telescopic horizontal structure, and the swing section is connected to the polishing machine body.

[0047] The base trolley 1 is the mobile foundation of the entire equipment, which is responsible for moving on the horizontal plane so as to accurately move the entire grinding equipment to the vicinity of the workpiece to be polished. The base trolley 1 may adopt a wheeled, crawler-type or other structure suitable for movement, and realize forward, backward, left turn, right turn and other movements through a motor or hydraulic drive or direct manual push. The stand 2 is vertically installed on the base trolley 1, which plays the role of supporting and fixing the vertical slide structure 3. The stand 2 has sufficient rigidity and stability to ensure that there is no shaking or tilting during the grinding process. The vertical slide structure 3 is movably connected to the stand 2 to achieve up and down movement. This lifting function enables the grinding and polishing structure 5 to accurately position and adjust the workpiece in the vertical direction; one end of the telescopic horizontal structure 4 is fixedly connected to the vertical slide structure 3, and the other end is connected to the grinding and polishing structure 5. Through the internal transmission mechanism, the telescopic horizontal structure 4 can be telescoped and fine-tuned in the horizontal direction to adapt to workpieces of different sizes and shapes. The grinding and polishing structure 5 includes a swing component 50 and a polishing machine body 51. The fixed end of the swing assembly 50 is connected to the telescopic horizontal structure 4, and the swing section is connected to the polishing machine body 51. The swing assembly 50 is swung by a driving mechanism to adapt to the curvature change of the workpiece surface. The polishing machine body 51 is responsible for the actual grinding and polishing operations, and may use different polishing tools such as grinding wheels, grinding belts, and grinding heads to remove burrs, oxide layers, etc. on the workpiece surface through high-speed rotation or reciprocating motion.

[0048] When working, first move the device to the vicinity of the workpiece to be polished by the base trolley 1. Then, adjust the polishing structure 5 to a suitable position and angle by the cooperation of the vertical slide structure 3 and the telescopic horizontal structure 4. Then, start the swing assembly 50 and the polishing machine body 51 to start polishing and polishing the workpiece. During the polishing process, the swing frequency and amplitude of the swing assembly 50, as well as the rotation speed and feed rate of the polishing machine body 51 can be adjusted as needed to obtain the best polishing effect.

[0049] In actual applications, in order to improve the automation and grinding accuracy of the equipment, it is usually equipped with an intelligent control system. The system can monitor the position, shape and grinding progress of the workpiece in real time through sensors, and automatically adjust the movement parameters and grinding parameters of the equipment according to the preset program and algorithm to achieve accurate and efficient grinding operations.

[0050] In summary, this large-scale intelligent mobile grinding equipment realizes accurate and efficient grinding operations on large and complex-shaped workpieces through the coordination of functions such as the movement of the base trolley 1, the support of the stand 2, the lifting and lowering of the vertical slide structure 3, the extension and fine-tuning of the telescopic horizontal structure 4, and the swinging and polishing of the grinding and polishing structure 5.

[0051] In some optional embodiments, the vertical slide structure 3 includes a first synchronous belt 30, a slide saddle 31, a first motor 35, a first driving wheel 32, a first driven wheel 33 and a first fixed block 34.

The first driven wheel 33 and the first fixed block 34 play the role of positioning and supporting the synchronous belt. When the first motor 35 rotates forward or reversely, the slide saddle 31 will rise or fall accordingly, thereby driving the telescopic horizontal structure 4 and the grinding and polishing structure 5 connected thereto to adjust in the vertical direction.

[0052] In some optional embodiments, the telescopic horizontal structure 4 includes a first telescopic arm 40 and a second telescopic arm 41. The first telescopic arm 40 is movably connected to the vertical slide structure 3, and one end of the second telescopic arm 41 extends into the slide cavity of the first telescopic arm 40 to telescope and move. When the transmission mechanism is activated, the second telescopic arm 41 will telescope in the first telescopic arm 40, thereby driving the grinding and polishing structure 5 connected thereto to adjust in the horizontal direction.

[0053] In some optional embodiments, the telescopic horizontal structure 4 further includes a second motor 42, a second gear 43, and a second rack 44. The second motor 42 drives the second gear 43 to rotate, and the second gear 43 meshes with the second rack 44, thereby driving the second telescopic arm 41 to extend and retract within the first telescopic arm 40; when the second motor 42 rotates forward or reversely, the second gear 43 moves along the second rack 44, thereby driving the second telescopic arm 41 to extend and retract.

[0054] In some optional embodiments, the telescopic horizontal structure 4 further includes a third slide rail 45 and a third slider 46. The third slide rail 45 is fixedly arranged along the length direction of the second telescopic arm 41, and the third slider 46 is arranged in the slide cavity of the first telescopic arm 40 and is slidably connected to the third slide rail 45.

The third motor 470 drives the third driving wheel 471 to rotate, and the third driving wheel 471 drives the second telescopic arm 41 to telescope in the first telescopic arm 40 through the third synchronous belt 473. The third driven wheel 474 plays the role of positioning and supporting the synchronous belt. The third fixing block 472 is fixedly connected to the second telescopic arm 41 and the third synchronous belt 473 to ensure the stability of the telescopic movement.

[0056] In some optional embodiments, the swing assembly 50 includes a base plate 500, a fourth motor 501, a reversing shaft 502, and an extension cylinder 503. The fourth motor 501 drives the reversing shaft 502 to rotate, and the output ends of the reversing shaft 502 are respectively arranged on both sides and fixedly connected to the extension cylinder 503. When the reversing shaft 502 rotates, it drives the extension cylinder 503 to swing in a horizontal plane. The driving rod of the extension cylinder 503 is fixedly connected to the polishing machine body 51, so the polishing machine body 51 will swing with the swing of the extension cylinder 503 to adapt to the curvature change of the workpiece surface.

[0057] In some optional embodiments, the leveling assembly 52 includes an adjustment shaft 520, a balance telescopic rod 521, and a fixed plate 522. The swing end of the swing assembly 50 is fixedly connected to the adjustment shaft 520, and the adjustment shaft 520 is perpendicular to the rolling direction of the polishing machine body 51. When the polishing machine body 51 is in the process of polishing, the curvature of the workpiece surface will change continuously, and the polishing machine body 51 can rotate and swing along the adjustment shaft 520 to adapt to the change of curvature of the workpiece surface. When tilting occurs during the swinging process, the balance telescopic rod 521 will extend and retract to ensure the stability of the polishing machine body 51 during the working process.

[0058] In some optional embodiments, the dust suction structure 7 includes a dust suction pipe 70 and a dust collector body 71. The dust collector body 71 is connected to one side of the polishing machine body 51 through the dust suction pipe 70. During the polishing process, the suction force generated by the dust collector body 71 will suck the generated dust and debris into the dust suction pipe 70, and then be discharged after filtering. This can reduce environmental pollution and protect the health of operators.

[0059] In some optional embodiments, the intelligent control structure 8 includes a controller, a sensor and an actuator.
