Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and more specifically, to a polishing device for processing automotive windshields. Background Technology

[0002] In existing technologies, polishing devices for processing automotive windshields still have certain structural and functional shortcomings. First, the spatial adjustment effect of the polishing wheel in this device is poor. In actual polishing operations, windshields of different types or with different curved surfaces often require the polishing wheel to be flexibly adjusted at multiple angles and spatial positions to ensure that the polished surface fully contacts the workpiece surface. However, the polishing wheel adjustment mechanism of existing devices is usually designed in a relatively simple way with a limited adjustment range, which cannot achieve multi-directional and fine adjustment. This results in uneven contact and many polishing dead corners during the polishing process, affecting the polishing quality and surface finish.

[0003] Secondly, the existing equipment also has inconveniences in terms of the installation, replacement and maintenance of polishing wheels. Since polishing wheels are usually fixed by bolts, ferrules and other means, their installation structure is relatively complex and the operating space is limited. This means that replacing polishing wheels requires disassembling multiple parts, which is not only time-consuming, but also prone to installation errors or damage to parts. In addition, polishing wheels are high-wear parts that need to be replaced or maintained regularly during long-term use. The inconvenience of disassembly and assembly will directly affect the maintenance efficiency of the equipment, increase downtime, and thus reduce the overall operating efficiency of the production line.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a polishing device for processing automotive windshields, comprising a polishing table, a polishing wheel, a space adjustment mechanism, a wheel mounting mechanism, and a disassembly and assembly auxiliary mechanism. The space adjustment mechanism includes a rotating frame and a guide rod. The rotating frames are symmetrically rotated and installed on both sides of the polishing table. The guide rod connects the two rotating frames. A threaded block is slidably installed on the guide rod. A threaded rod is installed between the rotating frames. The threaded block is threadedly connected to the threaded rod. The wheel mounting mechanism includes a clamping tube and an output shaft. A clamping plate is installed at one end of the output shaft. A longitudinal groove is formed on the outer wall of the clamping tube. A longitudinal block is slidably installed in the longitudinal groove. An inclined rail is installed on the inner wall of the clamping tube. A clamping block is slidably installed on the inclined rail. The clamping block can press against the bottom end of the clamping plate. An upper pressure ring is slidably installed longitudinally on the outer wall of the clamping tube. The upper pressure ring can push the clamping block to move.

[0006] The present invention is further configured such that the disassembly and assembly auxiliary mechanism includes an operating ring and a rotating ring. The operating ring is rotatably mounted on the outer wall of the clamping tube, and the rotating ring is mounted on the bottom end of the operating ring. A rotating groove is provided on the rotating ring. A fixing block is fixedly mounted on the outer wall of the clamping tube, and a positioning spring rod is mounted on the fixing block. The positioning spring rod can be embedded into the rotating groove step by step to make the operating ring rotate stably.

[0007] The present invention is further configured such that a threaded plate is installed on one end face of the operating ring, and a pressing ring on the threaded plate is threadedly connected to it.

[0008] The present invention is further configured such that a support plate is installed on the side of the polishing table, a first motor is installed on the top end of the support plate, and the output end of the first motor is connected to the rotating frame.

[0009] The present invention is further configured such that a second motor is mounted on the side of the rotating frame, and the output end of the second motor is connected to the threaded rod.

[0010] The present invention is further configured such that a mounting bracket is installed on one end face of the threaded block, and a polishing motor is installed on the mounting bracket, with the output shaft mounted on the polishing motor.

[0011] The present invention is further configured such that a connecting plate is installed at one end of the side wall of the clamping tube, the connecting plate is fixedly connected to the polishing wheel, and the clamping tube inserts the output shaft into the clamping connection.

[0012] The present invention is further configured such that a mating groove is provided on the top wall of the carding tube, so that the output shaft is fixed relative to the carding tube.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a polishing device for processing automotive windshields, which has the following beneficial effects: 1. Beneficial effects of the spatial adjustment mechanism: The first motor drives the rotating frame to rotate synchronously to achieve angle adjustment, and the second motor drives the threaded rod to drive the threaded block to slide along the guide rod to achieve lateral position adjustment. The two-degree-of-freedom motor-driven adjustment is flexible and precise, and can quickly adapt to baffles of different sizes and curved shapes, achieving precise positioning of the polishing wheel position and angle. The adjustment range is large and the positioning is accurate, significantly improving the adaptability and processing accuracy of polishing.

[0014] 2. Beneficial effects of the wheel mounting mechanism: The upper pressure ring pushes the longitudinal moving block to drive the clamping block to slide along the inclined rail. The longitudinal thrust is converted into radial clamping force by using the inclined plane principle to press the clamping plate. The clamping force is large, uniform and controllable. The matching groove provides additional relative fixed positioning. The polishing wheel can be quickly disassembled and assembled without tools. The operation is simple and quick, the connection is firm and reliable, and the efficiency of polishing wheel replacement and the convenience of maintenance are significantly improved.

[0015] 3. Beneficial effects of the disassembly and assembly auxiliary mechanism: When the operating ring is rotated, the threaded plate drives the upper pressure ring to move, making operation effortless and intuitive. The multi-stage rotating grooves on the rotating ring, together with the positioning spring rod, provide progressive elastic positioning. The operation process has clear tactile feedback, preventing accidental rotation of the operating ring from causing the connection to loosen. It provides graded positioning and clear operational feedback, ensuring accurate and reliable locking position, and improving connection stability and operational safety. Attached Figure Description

[0021] Please see Figures 1-5 A polishing device for processing automotive windshields includes a polishing table 1, a polishing wheel 2, a space adjustment mechanism, a wheel mounting mechanism, and a disassembly and assembly auxiliary mechanism. The space adjustment mechanism includes a rotating frame 3 and a guide rod 4. The rotating frames 3 are symmetrically rotated and installed on both sides of the polishing table 1. The guide rod 4 connects the two rotating frames 3. A threaded block 5 is slidably mounted on the guide rod 4. A threaded rod 6 is installed between the rotating frames 3. The threaded block 5 is threadedly connected to the threaded rod 6. The wheel mounting mechanism includes a clamping tube 7 and an output shaft 8. A clamping plate 9 is installed at one end of the output shaft 8. A longitudinal movement groove 10 is formed on the outer wall of the clamping tube 7. A longitudinal movement block 11 is slidably installed in the longitudinal movement groove 10. An inclined rail 12 is installed on the inner wall of the clamping tube 7. A clamping block 13 is slidably mounted on the inclined rail 12. The clamping block 13 can press against the bottom end of the clamping plate 9. An upper pressure ring 14 is slidably mounted longitudinally on the outer wall of the clamping tube 7. The upper pressure ring 14 can push the clamping block 13 to move.

[0022] In this embodiment, after the first motor 22 starts, it drives the rotating frame 3 to rotate synchronously. The two rotating frames 3 are connected by the guide rod 4 to maintain synchronous movement, realizing the overall angle adjustment of the polishing wheel 2. The second motor 23 drives the threaded rod 6 to rotate, and the threaded block 5 is threaded on the threaded rod 6 and slides along the guide rod 4 to realize the lateral position adjustment of the polishing wheel 2 assembly. By combining the two degrees of freedom of rotation and translation, it can flexibly adapt to the polishing needs of baffles of different sizes and curved shapes, and quickly and accurately locate the polishing position. During installation, the clamping pipe 7 is inserted into the output shaft 8, and the clamping pipe is inserted into the output shaft 8. Plate 9 enters the inside of clamping tube 7 and is fixed relative to the mating groove 27. Clamping block 13 slides on inclined rail 12. The longitudinal moving block 11 at the outer end moves longitudinally within the longitudinal moving groove 10 for guidance. When the upper pressure ring 14 presses down, it pushes the longitudinal moving block 11 to drive clamping block 13 to slide up along inclined rail 12. Using the principle of inclined plane, it gradually presses towards the bottom end of clamping plate 9, firmly clamping clamping plate 9 and completing the quick fixed connection between polishing wheel 2 and output shaft 8. When disassembling, the operation is reversed. The upper pressure ring 14 moves up to release pressure, and clamping block 13 slides down to release clamping plate 9, so that the disassembly and replacement of polishing wheel 2 can be completed quickly.

[0023] The disassembly and assembly auxiliary mechanism includes an operating ring 15 and a rotating ring 16. The operating ring 15 is rotatably mounted on the outer wall of the clamping tube 7. The rotating ring 16 is mounted on the bottom end of the operating ring 15. A rotating groove 17 is provided on the rotating ring 16. A fixing block 18 is fixedly mounted on the outer wall of the clamping tube 7. A positioning spring rod 19 is mounted on the fixing block 18. The positioning spring rod 19 can be embedded into the rotating groove 17 step by step to make the operating ring 15 rotate stably.

[0024] In this embodiment, when the operator rotates the operating ring 15, the threaded plate 20 pushes the upper pressure ring 14 to move longitudinally along the outer wall of the clamping tube 7. The upper pressure ring 14 moves down to push the longitudinal moving block 11, driving the clamping block 13 to slide up along the inclined rail 12 to press against the clamping plate 9, thus completing the locking. The rotating ring 16 at the bottom end of the operating ring 15 is provided with a multi-level rotating groove 17. The positioning spring rod 19 on the fixing block 18 can be embedded into the rotating groove 17 step by step to provide graded elastic positioning for the operating ring 15. There is clear positioning feedback during the operation, which prevents the operating ring 15 from rotating accidentally and ensures that the locked state is stable and reliable. When adjustment is required, force is applied to overcome the elasticity of the positioning spring rod 19, and the operating ring 15 can be rotated to complete the locking or unlocking operation.

[0025] Please see Figures 1-5 As a further implementation of the overall equipment: a threaded plate 20 is installed on one end face of the operating ring 15, and a pressure ring 14 is threadedly connected to the threaded plate 20. A support plate 21 is installed on the side of the polishing table 1, and a first motor 22 is installed on the top end of the support plate 21. The output end of the first motor 22 is connected to the rotating frame 3. A second motor 23 is installed on the side of the rotating frame 3, and the output end of the second motor 23 is connected to the threaded rod 6. A mounting bracket 24 is installed on one end face of the threaded block 5, and a polishing motor 25 is installed on the mounting bracket 24. The output shaft 8 is installed on the polishing motor 25. A connecting plate 26 is installed on one end of the side wall of the clamping tube 7. The connecting plate 26 is fixedly connected to the polishing wheel 2. The clamping tube 7 fits the output shaft 8 into the clamping device. A mating groove 27 is opened on the top wall of the clamping tube 7 so that the output shaft 8 and the clamping tube 7 are relatively fixed.

[0026] More specifically, in use, based on the size and curved shape of the baffle, the first motor 22 is started to drive the rotating frame 3 to rotate and adjust the angle of the polishing wheel 2. The second motor 23 is started to drive the threaded rod 6 to rotate. The threaded block 5 slides along the guide rod 4 to adjust the lateral position of the polishing wheel 2, quickly completing the spatial position and angle adjustment of the polishing wheel 2. When the polishing wheel 2 needs to be replaced, the operating ring 15 is rotated, the threaded plate 20 pushes the upper pressure ring 14 to move down, and the upper pressure ring 14 pushes the longitudinal moving block 11 to drive the clamping block 13 to slide up along the inclined rail 12 to press the clamping plate 9, completing the quick fixed connection between the polishing wheel 2 and the output shaft 8. The positioning spring rod 19 is inserted and rotated step by step. Slot 17 provides clear locking position feedback to ensure a firm and reliable connection. When the polishing motor 25 is started, the output shaft 8 drives the polishing wheel 2 to rotate at high speed to polish the surface of the baffle. During the polishing process, the position and angle of the polishing wheel 2 can be adjusted in real time through the space adjustment mechanism as needed to adapt to the curved surface shape of different parts of the baffle and ensure uniform polishing quality. When the polishing wheel 2 needs to be replaced after wear, the operating ring 15 is rotated in the reverse direction, the upper pressure ring 14 moves up to release the clamping block 13, and the connection between the polishing wheel 2 and the output shaft 8 is quickly released, completing the quick disassembly and replacement of the polishing wheel 2. The operation is simple and quick without tools.

[0027] In summary, when the overall equipment is in use or running: when the space adjustment mechanism is required, the first motor 22 starts and drives the rotating frame 3 to rotate synchronously. The two rotating frames 3 on both sides are connected by the guide rod 4 to maintain synchronous movement, thereby realizing the overall angle adjustment of the polishing wheel 2. The second motor 23 drives the threaded rod 6 to rotate, and the threaded block 5 is threaded on the threaded rod 6 and slides along the guide rod 4 to realize the lateral position adjustment of the polishing wheel 2 assembly. Through the combination of rotation and translation, the equipment can flexibly adapt to the polishing needs of baffles of different sizes and curved shapes, and quickly and accurately locate the polishing position.

[0028] When the wheel mounting mechanism is in operation, during installation, the clamping tube 7 is inserted into the output shaft 8, the clamping plate 9 enters the clamping tube 7 and is fixed relative to the mating groove 27, the clamping block 13 slides on the inclined rail 12, and the longitudinal moving block 11 at the outer end moves longitudinally within the longitudinal moving groove 10 for guidance. When the upper pressure ring 14 presses down, it pushes the longitudinal moving block 11 to drive the clamping block 13 to slide up along the inclined rail 12, gradually pressing it towards the bottom end of the clamping plate 9 using the inclined plane principle, thus firmly clamping the clamping plate 9 and completing the quick fixed connection between the polishing wheel 2 and the output shaft 8. When disassembling, the operation is reversed. The upper pressure ring 14 moves up to release the pressure, and the clamping block 13 slides down to release the clamping plate 9, thus quickly completing the disassembly and replacement of the polishing wheel 2.

[0029] When the auxiliary mechanism needs to be disassembled and operated, when the operator rotates the operating ring 15, the threaded plate 20 pushes the upper pressure ring 14 to move longitudinally along the outer wall of the clamping tube 7. The upper pressure ring 14 moves down and pushes the longitudinal moving block 11, driving the clamping block 13 to slide up along the inclined rail 12 and press against the clamping plate 9 to complete the locking. The rotating ring 16 at the bottom of the operating ring 15 is provided with multi-level rotating grooves 17. The positioning spring rod 19 on the fixed block 18 can be embedded into the rotating grooves 17 step by step to provide graded elastic positioning for the operating ring 15. There is clear positioning feedback during operation to prevent the operating ring 15 from rotating accidentally and to ensure that the locked state is stable and reliable. When adjustment is required, force is applied to overcome the elasticity of the positioning spring rod 19, and the operating ring 15 can be rotated to complete the locking or unlocking operation.

[0030] In use, based on the size and curved shape of the baffle, the first motor 22 is started to drive the rotating frame 3 to rotate and adjust the angle of the polishing wheel 2. The second motor 23 is started to drive the threaded rod 6 to rotate. The threaded block 5 slides along the guide rod 4 to adjust the lateral position of the polishing wheel 2, quickly completing the spatial position and angle adjustment of the polishing wheel 2. When the polishing wheel 2 needs to be replaced, the operating ring 15 is rotated, the threaded plate 20 pushes the upper pressure ring 14 to move down, and the upper pressure ring 14 pushes the longitudinal moving block 11 to drive the clamping block 13 to slide up along the inclined rail 12 to press the clamping plate 9, completing the quick fixed connection between the polishing wheel 2 and the output shaft 8. The positioning spring rod 19 is inserted into the rotating groove 1 step by step. 7. Provides clear locking position feedback to ensure a firm and reliable connection. Start the polishing motor 25, and the output shaft 8 drives the polishing wheel 2 to rotate at high speed to polish the surface of the baffle. During the polishing process, the position and angle of the polishing wheel 2 can be adjusted in real time through the space adjustment mechanism as needed to adapt to the curved surface shape of different parts of the baffle and ensure uniform polishing quality. When the polishing wheel 2 needs to be replaced after wear, rotate the operating ring 15 in the opposite direction, and the upper pressure ring 14 moves up to release the clamping block 13, quickly disconnecting the polishing wheel 2 from the output shaft 8 and completing the quick disassembly and replacement of the polishing wheel 2. The operation is simple and quick without tools.
