[0027] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1:

[0029] Please see Figures 1-7 This application provides a rapid positioning polishing device for automotive parts, including a base 1 and a polishing machine 2. The polishing machine 2 is located above the base 1, and a positioning mechanism 3 for positioning and calibrating the orientation is installed on the polishing machine 2. A fixed seat 11 is fixedly connected to the top of the polishing machine 2, and a rotating ball 5 is slidably connected inside the fixed seat 11. An electric push rod 7 is installed above the polishing machine 2, and the telescopic end of the electric push rod 7 is fixedly connected to the rotating ball 5. A conical opening is provided on the fixed seat 11, and the diameter of the conical opening is larger than the diameter of the telescopic end of the electric push rod 7. The conical opening is provided for the circumferential rotation of the telescopic end of the electric push rod 7 and the rotating ball 5, which can realize adaptive adjustment of orientation and achieve rapid positioning in conjunction with the positioning mechanism 3. The positioning mechanism 3 includes a slide rod 34, which is elastically slidably connected to the polishing machine 2. A mounting box 35 is fixedly connected to the slide rod 34, and a pressure sensor 4 is installed inside the mounting box 35. One side of the pressure sensor 4 extends to the outside of the mounting box 35, so that the pressure sensor 4 contacts the surface to be polished.

[0030] The positioning mechanism 3, on the one hand, can avoid positional deviations caused by polishing and play a limiting role during polishing. On the other hand, through the cooperation of the positioning mechanism 3 and multiple pressure sensors 4, polishing is carried out only when multiple pressure sensors 4 are in stable contact with the workpiece to be polished and the values ​​of each pressure sensor 4 are the same or similar. Thus, the multiple pressure sensors 4 can ensure that the polishing machine 2 is perpendicular to the polishing surface, ensuring the precision and accuracy of polishing and making the polished surface smoother.

[0031] The fixed base 11, the rotating ball 5, and the electric push rod 7 work together to drive the entire polishing machine 2 to move up and down, so that the polishing machine 2 comes into contact with the surface to be polished. The rotating ball 5 can adaptively adjust its position. When facing an inclined surface to be polished, it can quickly adjust its position so that the grinding disc 10 on the polishing machine 2 is parallel to the surface to be polished, thereby making the polished surface smoother.

[0032] Please see Figures 1-3 The positioning mechanism 3 further includes a mounting ring 31, which is fixedly connected to the outer wall of the polishing machine 2. Multiple connecting rods 32 are fixedly connected to the mounting ring 31, and a fixed cylinder 33 is fixedly connected to the connecting rods 32. A sliding rod 34 is slidably connected inside the fixed cylinder 33. A first spring 36 is connected inside the fixed cylinder 33. The first spring 36 is connected to the sliding rod 34. The first spring 36 is used for the extension and retraction of the pressure sensor 4. Before polishing, the pressure sensor 4 contacts the polishing surface in advance. Then, the electric push rod 7 drives the polishing machine 2 to continue to move downward, so that the grinding disc 10 on the polishing machine 2 contacts the polishing surface. During this process, the first spring 36 is compressed, and the pressure sensor 4 continues to contact the polishing surface.

[0033] The working process of the positioning mechanism 3 is as follows: when the pressure sensors 4 on the multiple slide rods 34 are in contact with the surface to be polished, each pressure sensor 4 will report the current pressure value. If the value of a certain pressure sensor 4 reaches the set threshold in advance, it means that the current orientation of the polishing machine 2 is not parallel to the surface to be polished. At this time, the pressure sensor 4 at the lower pressure will continue to move and press with the polishing machine 2. The rotating ball 5 will adaptively rotate within the fixed seat 11 to adjust the overall orientation of the polishing machine 2 until the pressure values ​​reported by all pressure sensors 4 fall into the same preset range. At this time, the polishing disc 10 of the polishing machine 2 is exactly parallel and in contact with the surface to be polished, completing the rapid positioning calibration. Then the polishing machine 2 can be started to carry out the polishing operation.

[0034] Please see Figure 2 , Figure 3The polishing machine 2 is equipped with a grinding disc 10. The height of the mounting box 35 and the pressure sensor 4 is lower than that of the grinding disc 10. This arrangement allows the polishing machine 2 to be positioned in advance by the positioning mechanism 3 and the pressure sensor 4, and also ensures that the grinding disc 10 on the polishing machine 2 is parallel to the polishing surface, thereby making the polished surface smoother.

[0035] Example 2:

[0036] Based on Example 1, please refer to Figure 4 The base 1 is equipped with two electric slide rails 12, and a slide block 13 is slidably connected to the electric slide rails 12. A clamping mechanism 9 for fixing the workpiece to be polished is installed on the slide block 13. The electric slide rails 12 drive the slide block 13 and the clamping mechanism 9 on it to move, so that the clamping mechanism 9 can clamp the workpiece to be polished.

[0037] Please see Figures 4-5 The clamping mechanism 9 includes a connecting plate 93, which is fixedly connected to two slide blocks 13 on the same side. A clamping plate 94 is fixedly connected to the connecting plate 93. Positioning rods 91 are fixedly connected to both ends of the connecting plate 93. Limiting rods 92 are fixedly connected to the connecting plate 93. A moving plate 96 is slidably connected to the limiting rods 92. The limiting rods 92 are used to limit the movement of the moving plate 96. The two ends of the moving plate 96 are provided with insertion mechanisms 6 that are fixed to the positioning rods 91. The moving plate 96 is fixed by the insertion mechanisms 6, so that the moving plate 96 can be fixed at different heights, thereby enabling the positioning of the workpiece to be polished at different heights. A pressure plate 95 is connected to the insertion mechanism 6. The pressure plate 95 and the clamping plate 94 cooperate to achieve the positioning of the workpiece to be polished.

[0038] The working principle of the clamping mechanism 9 is as follows: the workpiece to be polished is placed above the clamping plate 94, and the lever 66 is moved to slide along the limiting groove 67, which drives the moving rod 63 and the insert block 64 to compress the second spring 65 and move into the connecting cylinder 62, so that the insert block 64 is disengaged from the limiting position of the positioning tooth 61. At this time, the moving plate 96 can be slid along the limiting rod 92 to adjust the height of the pressure plate 95 until the pressure plate 95 presses the workpiece to be polished tightly onto the surface of the clamping plate 94. Then, the lever 66 is released, and the second spring 65 elastically resets, pushing the moving rod 63 and the insert block 64 to reset. The insert block 64 re-engages into the gap of the corresponding positioning tooth 61 to complete the locking, thus realizing the quick clamping and fixing of the workpiece to be polished. For workpieces of different thicknesses, the above operation can be repeated to adjust the position of the pressure plate 95. It has strong adaptability and the positioning and clamping operation is convenient and efficient.

[0039] When this equipment is working, the clamping mechanism 9 first fixes the automotive parts to be polished, and then the electric slide rail 12 adjusts the parts to the preset polishing position. Subsequently, the electric push rod 7 drives the polishing machine 2 to move downward, and multiple pressure sensors 4 contact the surface to be polished in sequence until the pressure values ​​fed back by all pressure sensors 4 fall into the preset range, completing the rapid positioning and calibration of the polishing position. Finally, the polishing machine 2 is started to drive the grinding disc 10 to rotate, and the polishing operation can be carried out. The entire positioning process is highly automated, requires no repeated manual adjustments, has high positioning accuracy, and effectively improves the efficiency and quality of automotive parts polishing.

[0040] Please see Figures 4-5 The insertion mechanism 6 includes a connecting cylinder 62, a movable rod 63 slidably connected inside the connecting cylinder 62, the movable rod 63 extending to the outside of the connecting cylinder 62 and fixedly connected to an insertion block 64, a positioning tooth 61 fixedly connected to the positioning rod 91, the insertion block 64 and the positioning tooth 61 cooperating, a second spring 65 provided inside the connecting cylinder 62, the second spring 65 connected to the movable rod 63, a limit groove 67 formed on the connecting cylinder 62, a toggle block 66 fixedly connected to the movable rod 63, and the toggle block 66 slidably connected within the limit groove 67.

[0041] The insertion mechanism 6 enables rapid positioning of the moving plate 96, thereby adjusting the height of the pressure plate 95 on the moving plate 96 to accommodate polished parts of different heights and increase the application range of the clamping mechanism 9.

[0042] Example 3:

[0043] Based on Example 2, please refer to Figure 7 A moving mechanism 8 is provided above the electric push rod 7. The moving mechanism 8 includes a first slide cylinder 82 and a second slide cylinder 84. A first moving block 85 is slidably connected inside the first slide cylinder 82, and a second moving block 87 is slidably connected inside the second slide cylinder 84. The second slide cylinder 84 and the first moving block 85 are fixedly connected. The electric push rod 7 is mounted on the second moving block 87. A first lead screw 86 is rotatably connected inside the first slide cylinder 82. The first lead screw 86 and the first moving block 85 are threadedly connected. A first motor 81 is installed at the end of the first slide cylinder 82. The output end of the first motor 81 is fixedly connected to the first lead screw 86.

[0044] The movable mechanism 8 can drive the polishing machine 2 to move any point in the plane, thereby polishing the workpiece.

[0045] Please see Figure 7The second slide cylinder 84 is rotatably connected to a second lead screw 88, which is threadedly connected to a second moving block 87. A second motor 83 is installed at the end of the second slide cylinder 84, and the output end of the second motor 83 is fixedly connected to the second lead screw 88.

[0046] The working process of the moving mechanism 8 is as follows: the first motor 81 drives the first lead screw 86 to rotate, which drives the first moving block 85 to move axially along the first slide cylinder 82, thereby driving the second slide cylinder 84 to move synchronously as a whole, realizing the adjustment of the polishing machine 2 in one axial position; the second motor 83 drives the second lead screw 88 to rotate, which drives the second moving block 87 to move axially along the second slide cylinder 84, thereby driving the electric push rod 7 and the polishing machine 2 below to realize the position adjustment in another vertical axis. The movement of the two axes cooperates with each other, which can drive the grinding disc 10 to move to any specified position on the surface of the workpiece to be polished, and complete the polishing operation of different areas. There is no need to repeatedly adjust the clamping position of the workpiece to be polished, which simplifies the polishing process.

[0047] In summary, this rapid positioning automotive parts polishing equipment, through the cooperation of positioning mechanism 3, adaptive rotation structure and moving clamping mechanism 9, can quickly complete the parallel positioning calibration of the grinding disc 10 and the surface to be polished before the polishing operation. It has high positioning accuracy and does not require repeated manual adjustments. It is not only suitable for processing automotive parts of different sizes and specifications, but also effectively improves the efficiency of polishing and the flatness of the processed surface. It solves the problems of low positioning efficiency and large manual calibration errors of existing polishing equipment, and is suitable for batch polishing of automotive parts.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
