Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, specifically a multi-station polishing machine. Background Technology

[0002] A polishing machine is a high-efficiency surface treatment device. It uses a high-speed rotating polishing wheel or polishing pad, along with a special polishing agent, to grind and polish the surfaces of metal, stone, and plastic materials. It can quickly remove scratches and oxide layers, and improve the surface smoothness and gloss. It is widely used in industrial manufacturing, automotive detailing, and home decoration.

[0003] Polishing machines can significantly improve the surface finish of materials, remove scratches, oxide layers, and minor imperfections, making the surface smoother and brighter, and enhancing the appearance quality of products. Therefore, polishing machines are necessary. However, traditional polishing machines usually use a set of drive structures to drive one station for polishing, requiring processing one piece at a time. This makes it impossible to process multiple workpieces simultaneously, reducing the polishing efficiency. At the same time, it is not convenient to adjust the angle of the polishing disc. When the polishing disc angle is not adjustable, the processing effect on complex curved workpieces is limited. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 As shown, a multi-station polishing machine includes a mounting frame 1, a worktable 2 fixed to the inner wall of the mounting frame 1, multiple sets of suction cups 3 on the top of the worktable 2, and a mounting block 4 fixedly connected to the inner wall of the worktable 2. A drive assembly 5 is provided on one side of the mounting block 4. The mounting frame 1 serves as the basic support structure of the entire machine, providing a stable mechanical structure and ensuring that all components are firmly installed. The worktable 2 is used to support the multiple sets of suction cups 3, providing a stable placement platform for the workpiece. At the same time, the drive assembly 5 is fixed by the mounting block 4 on the inner wall. The suction cups 3 are used to directly support the workpiece and are linked with the adjustment assembly 6 through the bottom connecting rod 62 to achieve synchronous rotation. The mounting block 4 is used to fix the servo motor 51 in the drive assembly 5 to ensure its relative position with the worktable 2 is stable.

[0017] The adjustment component 6 is located on one side of the drive component 5. The adjustment component 6 includes a first gear 61 located on one side of the drive component 5, and the number of first gears 61 is set to multiple sets. A connecting rod 62 is fixedly connected to the inner wall of the first gear 61, and one end of the connecting rod 62 is fixedly connected to the bottom of the suction cup 3. The first gear 61 is used to mesh with the toothed belt 53. When the toothed belt 53 rotates, it can drive the first gear 61 to rotate. The top of the connecting rod 62 is fixed to the suction cup 3, and the bottom is connected to the first gear 61 and the second gear 52, thereby transmitting the rotational power of the drive component 5 to the suction cup 3 to realize the rotation of the workpiece. It should be noted that the other first gears 61 mesh with the inner wall of the toothed belt 53.

[0018] Multiple tilting components 9 are all disposed on the outside of the mounting frame 1. Each tilting component 9 includes a mounting base 91 fixed to the outside of the mounting frame 1. The inner wall of the mounting base 91 is rotatably connected to a first cylinder 92 via a rotating shaft. The piston rod of the first cylinder 92 is rotatably connected to a connecting seat 93. The mounting base 91 is the fixed base of the first cylinder 92. The first cylinder 92 is mounted on the outside of the mounting frame 1, providing a support point for the extension and retraction of the first cylinder 92. The first cylinder 92 pushes the connecting seat 93 through the extension and retraction of its piston rod, causing the support frame 8 to rotate around the rotating shaft of the support base 7. The connecting seat 93 is used to connect the piston rod of the first cylinder 92 and the support frame 8, converting the linear extension and retraction motion of the first cylinder 92 into the rotational motion of the support frame 8, thus ensuring the adjustment of the tilt angle of the polishing component 18.

[0019] The drive assembly 5 includes a servo motor 51 fixed to one side of the mounting block 4. The output end of the servo motor 51 is fixedly connected to a second gear 52. The teeth of the second gear 52 mesh with a toothed belt 53, and the teeth of the toothed belt 53 mesh with the teeth of multiple sets of second gears 52. When the servo motor 51 in the drive assembly 5 is started, the output end of the motor drives the second gear 52 fixed to it to rotate. The second gear 52 drives the other multiple sets of second gears 52 to rotate synchronously through the toothed belt 53. The second gear 52 drives the connecting rod 62 and the first gear 61 to rotate. The top of the connecting rod 62 drives the suction cup 3 and the workpiece to rotate synchronously, realizing multi-station synchronous rotation.

[0020] The top of the mounting bracket 1 is fixedly connected to a support base 7. The inner wall of the support base 7 is rotatably connected to a support frame 8 via a pivot, and the bottom of the support frame 8 is fixedly connected to the top of the connecting seat 93. The support base 7 is the pivot point of the support frame 8 and is rotatably connected to the support frame 8 via a pivot, providing a fixed hinge point for the tilt adjustment of the support frame 8. The support frame 8 is the bearing frame of the polishing assembly 18. The top is equipped with a second cylinder 10 and a bearing plate 12, and the bottom is fixed to the connecting seat 93. It can rotate around the pivot of the support base 7 to achieve the overall tilt of the polishing assembly 18.

[0021] A second cylinder 10 is fixedly connected to the top of the support frame 8, and a moving block 11 is fixedly connected to the piston rod of the second cylinder 10. A bearing plate 12 is fixedly connected to the top of the moving block 11, and a slide block 13 is fixedly connected to the bottom of the bearing plate 12, with the slide block 13 slidably connected to the slide rail at the top of the support frame 8. A frame 14 is fixedly connected to the top of the bearing plate 12, and a fixing frame 15 is fixedly connected to the inner wall of the frame 14. A third cylinder 16 is fixedly connected to the inner wall of the fixing frame 15. A lifting frame 17 is fixedly connected to the piston rod of the third cylinder 16, and a polishing assembly 18 is installed on the inner wall of the lifting frame 17. The extension and retraction of the piston rod of the second cylinder 10 drives the moving block 11. The sliding of the support plate 12 allows for fine-tuning of the horizontal position of the polishing assembly 18. One end of the moving block 11 is fixed to the piston rod of the second cylinder 10, and the other end is connected to the support plate 12, transmitting the cylinder power to the support plate 12 for synchronous horizontal movement. The top of the support plate 12 is fixed to the frame 14, and the bottom is connected to the slide rail of the support frame 8 via a slide block 13, ensuring stability and straightness during horizontal movement. The slide block 13 is slidably connected to the slide rail at the top of the support frame 8, providing guidance for the horizontal movement of the support plate 12 and preventing deviation. The frame 14 serves as the mounting frame for the third cylinder 16, providing installation space for the fixing bracket 15 and the third cylinder 16. The fixing frame 15 is used to vertically fix the third cylinder 16 to the inner wall of the frame 14, ensuring that the piston rod of the third cylinder 16 extends and retracts vertically, and ensuring that the polishing assembly 18 rises and falls smoothly. The third cylinder 16 drives the lifting frame 17 and the polishing assembly 18 to move up and down through the extension and retraction of the piston rod, controlling the contact pressure and distance between the polishing assembly 18 and the workpiece surface. The lifting frame 17 is fixed to the piston rod of the third cylinder 16, and the polishing assembly 18 is installed on the inner wall, transmitting the vertical power of the third cylinder 16 to the polishing assembly 18 to achieve polishing pressure adjustment. The polishing assembly 18 is used to polish the workpiece. It is noted that the polishing assembly 18 consists of a motor and a polishing disc, with the motor fixed to the inner wall. The inner wall of the lifting frame 17 has a polishing disc fixed to the output end of the motor. It should be noted that each cylinder is used in conjunction with an air compressor, an air tank, a filter pressure reducing valve, a directional control valve, and a flow control valve. During use, the air compressor compresses the ambient air to the set pressure and stores it in the air tank. The filter pressure reducing valve further purifies the air and stabilizes the pressure, and then delivers it to the control valve through an air pipe. The directional control valve switches the airflow channel according to the electrical signal to determine the extension and retraction direction of the cylinder. The flow control valve adjusts the airflow speed and controls the cylinder movement speed. Compressed air enters the rod chamber or rodless chamber of the cylinder, pushing the piston to move. The piston drives the piston rod to output linear reciprocating motion.

[0022] Working principle: First, the workpieces to be polished are placed on the multiple suction cups 3 on the top of the worktable 2. The external pneumatic structure is activated to create negative pressure on the suction cups 3, tightly adhering to the workpieces. At this time, the piston rod of the second cylinder 10 extends and retracts, driving the moving block 11. The moving block 11 pulls the bearing plate 12 to slide along the slide rail of the support frame 8 via the slide seat 13 until the polishing assembly 18 is horizontally aligned with the workpiece on the suction cup 3. After reaching the position, the second cylinder 10 is closed, and at the same time, the first cylinder 92 in the tilting assembly 9 is activated. Through the connecting seat 93, the support frame 8 is pushed to rotate around the pivot of the support seat 7, causing the polishing assembly 18 to tilt to fit the surface of the workpiece. After the angle is confirmed, the first cylinder 92 is locked, and then the drive is activated. The servo motor 51 of the moving component 5 drives the second gear 52 to rotate through its output end. The gear belt 53 drives the other multiple sets of second gears 52 to rotate synchronously. Then, through the connecting rod 62 and the first gear 61, the suction cup 3 and the workpiece rotate. At the same time, the piston rod of the third cylinder 16 extends downward, pushing the lifting frame 17 and the polishing component 18 to descend until the polishing disc contacts the workpiece. The motor of the polishing component 18 is started, and the polishing disc rotates at high speed to polish. During the process, the pressure of the third cylinder 16 is finely adjusted through the flow control valve. After polishing is completed, the motor of the polishing component 18 is turned off first, and the piston rod of the third cylinder 16 is controlled to retract and reset, the servo motor 51 is turned off, and the suction cup 3 stops rotating.
