Description

Technical Field

[0001] This invention relates to the field of toilet seat manufacturing technology, specifically to a toilet seat polishing equipment. Background Technology

[0002] Toilet seats primarily function to cover the toilet seat. The mainstream materials used are urea-formaldehyde and PP plastic. During the manufacturing process of toilet seats, sanding is done to remove the parting line and burrs after demolding, in preparation for subsequent painting.

[0003] Existing toilet seat polishing equipment involves placing the toilet seat to be polished in a designated position and then quickly fixing it using a pneumatic clamp or suction cup. The fixed toilet seat is then moved, and multiple polishing wheels positioned in different locations and configurations rapidly polish the seat. However, in actual use, toilet seats (V-shaped, U-shaped) are typically wide at one end and narrow at the other. During vacuum suction or centering clamping by the pneumatic clamp, the workpiece is prone to rotation or shifting around the clamping point when subjected to cutting forces parallel to the clamping direction (e.g., when polishing the end). This results in poor stability, potentially leading to a smooth surface but uneven overall surface after polishing, or localized over-polishing, ultimately affecting the shape accuracy of the final product. Summary of the Invention

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a toilet seat grinding device. Simultaneously, two top support plates expand and tighten laterally from the inside of the workpiece, while the top support block tightens longitudinally from the narrow end of the workpiece. The movement trajectories in these two directions are perpendicular to each other, forming a robust triangular support structure inside the workpiece. This allows the device to adapt to toilet seats of different sizes but similar shapes, ensuring that they remain firmly in place even when subjected to cutting forces in all directions during subsequent high-speed grinding. This fundamentally avoids uneven grinding depth or edge defects caused by workpiece vibration, significantly improving processing accuracy and product qualification rate.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a toilet seat polishing device, including a polishing table, and a clamping mechanism for clamping the toilet seat is provided on the upper side of the polishing table. The clamping mechanism includes a clamping seat, and multiple top support frames that can be moved closer to or further away from the horizontal center of the clamping seat are slidably arranged inside the clamping seat. Each top support frame is provided with a top support plate on the side away from the vertical center of the clamping seat. A sliding column that can be moved closer to or further away from the vertical center of the clamping seat is slidably arranged inside the clamping seat on the side away from the top support frame. A top support block is provided at the end of the sliding column. The movement trajectory of the top support block is perpendicular to the movement trajectory of the top support plate.

[0006] As a further improvement of the present invention, the clamping mechanism further includes a rotating shaft rotatably disposed inside the clamping seat. Gears are sleeved on both the upper and lower sides of the outer arc surface of the rotating shaft. Two rack plates are provided on the side of the top support near the lateral center of the clamping seat. The rack plates are meshed with the gears. Two guide seats are provided inside the clamping seat. The rack plates are slidably connected to the guide seats. The clamping mechanism further includes a worm gear sleeved on the outer arc surface of the rotating shaft. A rotating seat is provided inside the clamping seat. A worm gear meshing with the worm gear is rotatably disposed on the rotating seat. A servo motor is provided on the outer side of the rotating seat. The output shaft of the servo motor is fixed to the worm gear by a coupling. The clamping mechanism further includes a slide cylinder disposed inside the clamping seat. The slide cylinder is slidably connected to a slide column. An adjusting screw is rotatably disposed inside the slide cylinder. The adjusting screw is threadedly connected to the slide column. A servo motor is provided on the outer side of the slide cylinder. The output shaft of the servo motor is fixed to the adjusting screw by a coupling.

[0007] As a further improvement of the present invention, a travel control mechanism for controlling the movement of the clamping seat is provided on the upper side of the grinding table. The travel control mechanism includes a grinding groove fixedly provided on the upper side of the grinding table, a guide rail provided inside the grinding groove, a sliding seat slidably provided on the guide rail, and multiple slide rails provided at the bottom of the sliding seat. The clamping seat is slidably provided between the slide rails. The travel control mechanism also includes an electric push rod 1 provided outside the sliding seat. The telescopic end of the electric push rod 1 is connected and fixed to the clamping seat. Multiple electric push rods 2 are provided outside the grinding groove. The telescopic ends of the electric push rods 2 are connected and fixed to the sliding seat.

[0008] As a further improvement of the present invention, a grinding mechanism is provided on the grinding groove. The grinding mechanism includes an XZ linear slide module disposed on the grinding groove. A sliding table is disposed on the slide of the XZ linear slide module. A grinding rod is rotatably disposed on the lower side of the sliding table. A sliding frame is also provided on the grinding groove. A lifting platform is slidably disposed inside the sliding frame. Multiple sliding rods are slidably disposed inside the lifting platform. Symmetrically distributed movable platforms are slidably disposed between the sliding rods. A rotating frame is rotatably disposed on the lower side of the movable platform via a rotating shaft. A grinding wheel is rotatably disposed on the rotating frame via a rotating shaft. The grinding mechanism also... The system includes a control motor 1 installed inside the sliding table, with its output shaft fixed to the grinding rod via a coupling; a control motor 2 installed on the rotating frame, with its output shaft fixed to the rotating shaft via a coupling; a control motor 3 installed inside the movable table, with its output shaft fixed to the rotating shaft via a coupling; symmetrically distributed electric push rods 3 installed inside the lifting table, with their telescopic ends connected and fixed to the movable table; and an electric push rod 4 installed on the upper side of the sliding frame, with its telescopic end connected and fixed to the lifting table.

[0009] As a further improvement of the present invention, a grinding box is provided on the upper side of the grinding table, a vacuum cleaner is provided on the upper side of the grinding box, and multiple vacuum pipes are provided between the vacuum cleaner and the grinding box; multiple support legs are provided on the lower surface of the grinding table.

[0010] In summary, this application has at least one of the following beneficial technical effects compared with the prior art: Firstly, the triangular positioning clamping mechanism perfectly solves this problem. The worm gear and rack mechanism driven by servo motor one controls the two top support plates to expand and clamp horizontally from the inside of the workpiece. At the same time, the lead screw mechanism driven by servo motor two controls a top support block to clamp vertically from the narrow end of the workpiece. The movement trajectories in these two directions are perpendicular to each other, forming a solid triangular support structure inside the workpiece. This clamping method can adapt to toilet seats of different sizes but similar shapes, ensuring that they do not loosen at all when subjected to cutting forces in all directions during subsequent high-speed grinding. Stable clamping is the primary prerequisite for obtaining a uniform and consistent grinding surface, fundamentally avoiding uneven grinding depth or edge defects caused by workpiece vibration, and significantly improving processing accuracy and product qualification rate.

[0011] Secondly, the self-adaptive locking of the fixture, the electric push rod precisely transporting the workpiece to the grinding station, the XZ slide module driving the grinding rod to complete the fine grinding of the upper surface, the multi-degree-of-freedom adjustable grinding wheel group synchronously processing the complex side, and finally the central dust collection system to clean up the dust in real time, greatly shorten the processing cycle of a single workpiece, enabling uninterrupted batch operation and improving production efficiency by orders of magnitude.

[0012] Thirdly, toilet seats not only require surface treatment on the top surface, but their sides often have complex curved surfaces, which places extremely high demands on the polishing process. Through the multi-degree-of-freedom adjustment of the side polishing wheel assembly, consisting of an electric push rod, a control motor, and the electric push rod, precise and independent control of height, angle, and horizontal movement is achieved. This means that regardless of how the workpiece contour changes, constant contact pressure and optimal polishing angle can be guaranteed, resulting in a uniform and smooth edge effect without over-polishing or missed polishing dead corners. This flexible processing capability, combined with the polishing rod controlled by a precision linear slide on the top surface, ensures that every three-dimensional surface of the workpiece achieves a consistent high-quality finish, meeting the stringent requirements of high-end products for appearance and feel, and enhancing product competitiveness.

[0013] Fourth, a closed grinding chamber was designed to physically isolate the entire grinding process from the external environment. During processing, a high-powered vacuum cleaner creates negative pressure airflow through multiple suction ports distributed within the chamber, instantly capturing and removing the generated dust. This design brings multiple significant benefits: First, it maximizes the protection of the operator's respiratory health, fundamentally eliminating the risk of occupational diseases such as silicosis. Second, it maintains the cleanliness of the equipment interior and workshop environment, preventing dust from wearing and damaging precision moving parts of the equipment (such as lead screws, guide rails, and motors), extending the equipment's service life, and reducing maintenance frequency.

[0017] like Figure 4 , 6 As shown, a toilet seat polishing device includes a polishing table 501, and a clamping mechanism for clamping the toilet seat is provided on the upper side of the polishing table 501. The clamping mechanism includes a clamping seat 101. Multiple top support frames 106, which can move closer to or further away from the lateral center of the clamping seat 101, are slidably arranged inside the clamping seat 101. Each top support frame 106 has a top support plate 107 on its side away from the vertical center of the clamping seat 101. A sliding column 113, which can move closer to or further away from the vertical center of the clamping seat 101, is slidably arranged inside the clamping seat 101 on its side away from the top support frames 106. A top support block 114 is provided at the end of the sliding column 113, and the movement trajectory of the top support block 114 is perpendicular to the movement trajectory of the top support plate 107. The clamping mechanism also includes a rotating shaft 102 rotatably arranged inside the clamping seat 101.

The output shaft of the servo motor 116 is fixed to the adjusting screw 115 by a coupling.

[0018] like Figure 1 , 2As shown, a travel control mechanism for controlling the movement of the clamping seat 101 is provided on the upper side of the grinding table 501. The travel control mechanism includes a grinding groove 201 fixedly installed on the upper side of the grinding table 501. A guide rail 202 is provided inside the grinding groove 201. A sliding seat 203 is slidably installed on the guide rail 202. Multiple slide rails 204 are provided at the bottom of the sliding seat 203. The clamping seat 101 is slidably installed between the slide rails 204. The travel control mechanism also includes an electric push rod 205 provided on the outside of the sliding seat 203. The telescopic end of the electric push rod 205 is connected and fixed to the clamping seat 101. Multiple electric push rods 206 are provided on the outside of the grinding groove 201. The telescopic ends of the electric push rods 206 are connected and fixed to the sliding seat 203.

[0019] like Figure 2 , 3 As shown in Figure 4, a grinding mechanism is provided on the grinding groove 201. The grinding mechanism includes an XZ linear slide module 301 mounted on the grinding groove 201. A sliding table 302 is mounted on the slide of the XZ linear slide module 301. A grinding rod 303 is rotatably mounted on the lower side of the sliding table 302. A sliding frame 304 is also provided on the grinding groove 201. A lifting platform 305 is slidably mounted inside the sliding frame 304. Multiple sliding rods 306 are slidably mounted inside the lifting platform 305. Symmetrically distributed movable platforms 307 are slidably mounted between the sliding rods 306. A rotating frame 308 is rotatably mounted on the lower side of the movable platform 307 via a rotating shaft 102. A grinding wheel 309 is rotatably mounted on the rotating frame 308 via a rotating shaft. It also includes a control motor 310 installed inside the sliding table 302. The output shaft of the control motor 310 is fixed to the grinding rod 303 by a coupling. A control motor 311 is installed on the rotating frame 308. The output shaft of the control motor 311 is fixed to the rotating shaft by a coupling. A control motor 312 is installed inside the movable table 307. The output shaft of the control motor 312 is fixed to the rotating shaft 102 by a coupling. A symmetrically distributed electric push rod 313 is installed inside the lifting table 305. The telescopic end of the electric push rod 313 is connected and fixed to the movable table 307. An electric push rod 4 is installed on the upper side of the sliding frame 304. The telescopic end of the electric push rod 4 is connected and fixed to the lifting table 305.

[0020] like Figure 1 As shown, a grinding box 401 is provided on the upper side of the grinding table 501, a vacuum cleaner 402 is provided on the upper side of the grinding box 401, and multiple vacuum cleaner pipes 403 are provided between the vacuum cleaner 402 and the grinding box 401.

[0021] According to another embodiment of the invention, such as Figure 1 , 2 As shown, the lower surface of the grinding table 501 is provided with multiple support legs 502.

[0022] When in use, place the toilet seat to be polished on the clamping seat 101, and then control the servo motor 111 and servo motor 216 to run. The output shaft of servo motor 111 drives the worm gear 109 connected to it to rotate, which in turn drives the rotating shaft 102 of the worm gear 110 to rotate through the meshing relationship between the worm gear 109 and the worm wheel 110. During the rotation of the rotating shaft 102, the gears 103 on the upper and lower sides of its outer arc surface rotate, which causes each gear 103 to drive the two rack plates 105 meshing with it to move away from the lateral center of the clamping seat 101. This causes the top support brackets 106 on both sides to move away from the lateral center of the clamping seat 101, so that the top support plate 107 on each top support bracket 106 approaches and abuts against the lower edge of the toilet seat fastened to the clamping seat 101. The output shaft of servo motor 116 drives the adjusting screw 115 connected to it to rotate, which in turn drives the sliding column 113 to move away from the vertical center of the clamping seat 101 through the thread relationship between the adjusting screw 115 and the sliding column 113. This causes the sliding column 113 to move away from the vertical center of the clamping seat 101, which in turn drives the sliding column 113 to move away from the vertical center of the clamping seat 101. The top support block 114 is close to and abuts against the lower edge of the toilet seat on the clamping seat 101; since the movement trajectory of the top support plate 107 and the top support block 114 is perpendicular, the top support plates 107 on both sides can cooperate with the top support block 114 to triangularly position and clamp the toilet seat on the clamping seat 101. Since the shape of the toilet seat is narrow at one end and wide at the other end, the toilet seat can be stably clamped and fixed by the triangular positioning of the top support plates 107 on both sides and the top support block 114; 07 While horizontally expanding and tightening from the inside of the workpiece, the top support block 114 tightens longitudinally from the narrow end of the workpiece. The movement trajectories of these two directions are perpendicular to each other, forming a solid triangular support structure inside the workpiece. This structure can adapt to toilet seats of different sizes but similar shapes, ensuring that they do not loosen at all when subjected to cutting forces in all directions during subsequent high-speed grinding. This fundamentally avoids uneven grinding depth or edge defects caused by workpiece vibration, significantly improving processing accuracy and product qualification rate. Then, control the operation of the electric push rod 206, so that the telescopic end of the electric push rod 206 drives the sliding seat 203 to slide with the guide rail 202, thereby driving the sliding seat 203 and the clamping seat 101 set on the sliding seat 203 into the interior of the polishing box 401. Then, control the operation of the electric push rod 205, so that the electric push rod 205 drives the clamping seat 101 to slide with the slide rail 204 on the sliding seat 203, so that the clamping seat 101 drives the toilet seat that is clamped and fixed thereon to move stably inside the polishing box 401. During the movement of the toilet seat, the XZ linear slide module 301 and the first control motor 310 are operated, causing the XZ linear slide module 301 to move the slide table 302 and the polishing rod 303 mounted on the slide table 302, thereby adjusting the horizontal and vertical positions of the polishing rod 303. The first control motor 310 drives the polishing rod 303 to rotate, allowing the polishing rod 303 to polish the upper surface of the toilet seat. The electric push rod 4 is operated, causing its extension end to move the lifting platform 305, thereby adjusting the height of the lifting platform 305 and the height of the polishing wheels 309 on both sides. Then, the second control motor 311 is operated, causing the second control motor 311 to move. The output shaft of 311 drives the grinding wheel 309 connected to it to rotate, thereby causing the grinding wheels 309 on both sides to rotate synchronously. The control motor 312 drives the rotating frame 308 connected to it to rotate, thereby causing the rotating frame 308 to drive the grinding wheel 309 mounted on it to rotate. This allows the grinding angle of the grinding wheels 309 on both sides to be adjusted. Then, the electric push rod 313 is controlled to operate, so that the extension end of the electric push rod 313 drives the grinding wheel 309 to adjust horizontally. By controlling the horizontal position and grinding angle of the grinding wheels 309 on both sides, the outer edge of the toilet seat can be ground, thereby enabling fast and efficient grinding of the upper surface and side edge of the toilet seat. During the polishing process, the vacuum cleaner 402 is controlled to operate, so that the vacuum cleaner 402 can suck up the dust generated by polishing in the polishing box 401 through the multiple suction pipes 403 set on it.

[0023] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
