[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Please see Figure 1-4A surface polishing device for ceramic craft production includes a polishing chamber 1. The polishing chamber 1 is equipped with a placement mechanism for positioning ceramic crafts and a polishing mechanism for polishing. The placement mechanism includes a rotary motor 2 fixed to the bottom of the polishing chamber 1 via a motor base 3, a placement seat 4 coaxially fixed to the output end of the rotary motor 2, a positioning plate 5 located directly above the placement seat 4, a lifting plate 7 rotatably connected to the upper end of the positioning plate 5 via a bidirectional thrust ball bearing 6, and a lifting device 8 located at the bottom of the polishing chamber 1 with the output end facing upwards on the lifting plate 7. An elastic pad 9 for buffering and shock absorption is attached to the bottom of the positioning plate 5, and a pressure sensor 10 for detecting clamping pressure is clamped between the output end of the lifting device 8 and the lifting plate 7. The grinding mechanism includes a slide rail 11 vertically fixed to the bottom of the grinding chamber 1, a slide seat 12 slidably mounted on the slide rail 11, a linear actuator 13 horizontally fixed to the slide seat 12 facing the placement mechanism, a U-shaped seat 14 fixed to the output end of the linear actuator 13, a grinding motor 16 rotatably mounted between two opposite side walls of the U-shaped seat 14 via a horizontal rotating shaft 15, and a grinding head 17 coaxially fixed to the output end of the grinding motor 16; a worm gear mechanism is provided on one side of the U-shaped seat 14 for driving the grinding motor 16 to rotate around the rotating shaft to adjust the angle of the grinding head 17.

[0021] In this embodiment: the grinding chamber 1 provides a closed working space for the equipment. In the placement mechanism, the rotary motor 2 is fixed to the bottom of the grinding chamber 1 via the motor base 3. Its output end drives the placement seat 4 to rotate, causing the ceramic crafts placed on the placement seat 4 to rotate synchronously. The lifting device 8 is fixed to the bottom of the grinding chamber 1 via the flange. Its output end pushes the lifting plate 7 to rise. The lifting plate 7 drives the positioning plate 5 to fall via the bidirectional thrust ball bearing 6. The elastic pad 9 at the bottom of the positioning plate 5 contacts the top of the ceramic crafts to clamp the workpiece. The elastic pad 9 can buffer the vibration during clamping and polishing to prevent the workpiece from shaking or being scratched. The pressure sensor 10 between the lifting device 8 and the lifting plate 7 detects the clamping pressure in real time to prevent the workpiece from being damaged by excessive clamping. In the grinding mechanism, the slide rail 11 is vertically fixed to the bottom of the grinding chamber 1. The slide block 12 can slide up and down along the slide rail 11 to adapt to workpieces of different heights. The linear actuator 13 is fixed on the slide block 12. Its output end pushes the U-shaped seat 14 and the grinding motor 16 closer to the workpiece. In the worm gear mechanism on one side of the U-shaped seat 14, the drive motor 21 is fixed to the U-shaped seat 14 via a base. The drive motor 21 drives the worm 20 to rotate, and the worm 20 drives the worm wheel 19, which is coaxially fixed to the shaft of the grinding motor 16, to rotate. This causes the grinding motor 16 to rotate around the shaft, adjusting the angle of the grinding head 17 to fit the irregular curved surface of the workpiece. The grinding motor 16 drives the grinding head 17 to rotate to achieve the polishing operation. The controller 18 on the outer wall of the grinding chamber 1 receives the signal from the pressure sensor 10 and synchronously adjusts the angle. The rotary motor 2, lifting device 8, linear drive 13, grinding motor 16, and drive motor 21 of worm gear mechanism are controlled to ensure that all components work together. The dust suction hoods 22 on both sides of the lifting plate 7 move synchronously with the lifting plate 7, and their dust suction ports face the workpiece. The dust generated during polishing is sucked in by the dust suction hoods 22 and transported to the dust collector 23 outside the grinding chamber 1 through the connecting pipe 24. The transparent window 25 on the front end of the grinding chamber 1 facilitates observation of the polishing process, and the rubber sealing strip 26 prevents dust leakage.

[0022] As a technical optimization of this utility model, a controller 18 is fixedly installed on the outer wall of the grinding chamber 1. The controller 18 is electrically connected to the pressure sensor 10, the linear driver 13, the lifting device 8, the rotary motor 2, the grinding motor 16, and the drive components of the worm gear mechanism, so as to regulate the action of each component according to the detection signal of the pressure sensor 10.

[0023] In this embodiment, automated equipment control is achieved. The controller 18 precisely controls the actions of components such as the lifting device 8, linear driver 13, and rotary motor 2 based on the clamping pressure signal detected by the pressure sensor 10, without the need for manual intervention, thus improving the ease of operation and polishing accuracy.

[0024] As a technical optimization of this utility model, the worm gear mechanism includes a worm wheel 19 coaxially fixed to one end of the rotating shaft, a worm 20 meshing with the worm wheel 19, and a drive motor 21 fixed to the side wall of the U-shaped seat 14 via a base; the output end of the drive motor 21 is coaxially fixed to the end of the worm 20 away from the worm wheel 19, and the drive motor 21 drives the worm 20 to rotate, thereby driving the worm wheel 19 and the grinding motor 16 to rotate synchronously.

[0025] In this embodiment, the transmission path between the worm gear 19 and the rotating shaft, and between the worm 20 and the drive motor 21, ensures that the drive motor 21 can stably drive the worm 20, the worm gear 19 and the grinding motor 16 to rotate synchronously, making the angle adjustment of the grinding head 17 more precise and stable, and further ensuring the polishing effect of irregular curved surfaces.

[0026] As a technical optimization of this utility model, dust collection hoods 22 are symmetrically fixed on both sides of the lifting plate 7, and the dust collection ports of the two dust collection hoods 22 are both set towards the storage seat 4; a dust collector 23 is fixedly installed on the outer wall of the grinding chamber 1, and the dust inlet end of the dust collector 23 is connected to the dust outlet end of the two dust collection hoods 22 respectively through the connecting pipe 24.

[0027] In this embodiment, the two dust hoods 22 move synchronously with the lifting plate 7, and the dust inlets face the storage seat 4, which can collect the particulate dust generated during the polishing process in a timely manner and transport it to the dust collector 23 through the connecting pipe 24, so as to avoid dust spreading and polluting the working environment and protect the health of the operators.

[0028] As a technical optimization of this utility model, the front end face of the grinding cavity 1 is hinged to a transparent window 25 for observing the polishing process, and the edge of the transparent window 25 is provided with a rubber sealing strip 26 for sealing.

[0029] In this embodiment: the transparent window 25 allows the operator to observe the polishing process in real time and detect polishing abnormalities in a timely manner; the rubber sealing strip 26 can enhance the sealing of the polishing chamber 1, prevent dust from leaking from the gaps in the transparent window 25, and improve the overall dustproof effect of the equipment.

[0030] As a technical optimization of this utility model, the linear actuator 13 is an electric push rod, the cylinder of the electric push rod is fixedly connected to the slide 12, and the push rod end of the electric push rod is fixedly connected to the U-shaped seat 14.

[0031] In this embodiment: the electric push rod operates stably and has high feed accuracy, which can accurately push the U-shaped seat and the grinding head 17 closer to or away from the workpiece, adapting to the polishing needs of ceramic crafts of different sizes and improving the accuracy of polishing feed control.

The cylinder of the hydraulic push rod is fixed to the bottom of the grinding chamber 1 through a flange, and the push rod end of the hydraulic push rod is in contact with the lower end face of the pressure sensor 10.

[0033] In this embodiment: the hydraulic push rod has a large thrust and smooth lifting. It is fixed by the flange to ensure a firm installation and can stably drive the lifting plate 7 and the positioning plate 5 to move up and down, so as to realize reliable clamping of workpieces of different heights and ensure the stability of the clamping process.

[0034] Working principle and usage process of this utility model: Open the transparent window 25 and place the ceramic craft on the shelf 4; start the lifting device 8 via the controller 18 to drive the lifting plate 7 to descend, and the pressure sensor 10 provides real-time feedback of pressure data. When the set value is reached, the lifting device stops, and the workpiece is reliably clamped; according to the processing requirements, the controller 18 controls the slide 12 to move up and down, the linear drive 13 to extend and retract horizontally, and the worm gear mechanism to move the grinding head 17 to the angle most suitable for the current polishing part of the workpiece; the rotary motor 2 starts to drive the workpiece to rotate, and at the same time the grinding motor 16 starts to drive the grinding head 17 to rotate at high speed to begin polishing; during the polishing process, the controller 18 can dynamically fine-tune the position and angle of the grinding head 17 to adapt to the changes in the curved surface and ensure uniform polishing without dead corners; throughout the polishing process, the dust collector 23 works continuously, absorbing the generated dust through the dust suction hood 22; after polishing is completed, all motors stop, the lifting device 8 rises back to release the workpiece, and the operator opens the transparent window 25 to take out the completed workpiece.
