Description

Technical Field

[0001] This utility model relates to the field of manufacturing machinery technology, and in particular to a ceramic liner bottom grinding device. Background Technology

[0002] Ceramic is an excellent material for rice cooker inner pots. It is corrosion-resistant, has good heat retention, and doesn't require a coating, preventing rice from sticking to the bottom. Therefore, high-end rice cookers use ceramic inner pots. After molding and sintering, the bottom of the ceramic inner pot needs to be polished to control its thickness. Existing ceramic inner pot polishing machines are either manual or automatic. The main problems with manual-feed polishing machines are: the inner pot height cannot be measured, the feed rate is controlled by hand, requiring manual measurement of the polishing height, leading to large measurement errors; water mist generated during polishing is not removed; the polishing coolant is not separated into solid and liquid components; and polishing efficiency is low. The main problems with automatic-feed polishing machines are: the inner pot height cannot be measured; the polishing guide rail is exposed to water mist, making it prone to rust; water mist generated during polishing is not removed; the polishing coolant is not separated into solid and liquid components; and polishing efficiency is low.

[0040] Place the ceramic inner liner on the rotary worktable 600 (select an empty worktable from the two available worktables), press the start button, and the transverse mechanism 200 will move the grinding mechanism 300 above the rotary worktable 600 where the ceramic inner liner is placed. Operating principle: The transverse drive component 201 drives the transverse lead screw 206 to rotate. The transverse lead screw nut 208, fixed to the mounting plate of the grinding mechanism 300, cannot rotate but moves left and right under the guidance of the transverse guide rail 205. The rotation drive component and reducer (rotary drive kit) rotate, driving the rotary table 602 to rotate via the rotary coupling 604, causing the ceramic inner liner to rotate under friction. The longitudinal drive component 302 drives the longitudinal lead screw 305 to move the mounting plate of the grinding drive component 313 downwards. As it approaches the ceramic inner liner, the grinding drive component 313 rotates. Since the grinding disc mounting seat 315 is connected to the output shaft of the grinding drive component 313, it further drives the grinding disc 316 to rotate. At this time, coolant pipe 801 begins supplying tap water for cooling. Under PLC control, the mounting plate of the grinding drive 313 moves down to a preset distance, then moves up to the initial height, and the grinding drive 313 stops rotating. During the grinding process, another empty rotary worktable 600 has been fitted with a new ceramic inner liner for the workpiece by the operator. After the operator clicks the continue button on the HMI (Human-Machine Interface), the traverse mechanism 200 moves the grinding mechanism 300 to the workstation with the workpiece installed. At the same time, the operator removes the workpiece that has just been ground. Throughout the grinding process, duct connector 502 is connected to the duct, and the mist extraction fan draws the generated water mist outdoors, where it is treated and then discharged.

[0041] Key Function Implementation Plan (I) Design of External Laser Thickness Measurement and Measurement Unit 1) Measurement principle: The dual-sensor differential thickness measurement method is adopted. A laser displacement sensor is installed above and below the measurement station to measure the distance to the upper and lower surfaces of the ceramic pot, respectively.

[0042] 2) Thickness Calculation: Workpiece thickness = known reference spacing - (D1 + D2). Where D1 and D2 are the real-time measured values ​​of the upper laser displacement measuring device 902 and the lower laser displacement measuring device 909. This calculation is performed by the PLC, which can effectively eliminate the error caused by slight workpiece vibration, and the measurement accuracy is extremely high.

[0043] 3) Anti-interference measures: The measuring station and the grinding station are completely separated and located outside the warehouse.

[0044] Red or blue laser sensors (upper laser displacement measuring device 902 and lower laser displacement measuring device 909) are selected because their shorter wavelengths and stronger anti-interference capabilities compared to ordinary red light provide superior performance on humid and misty surfaces. The sensors themselves should have an IP67 or higher protection rating.

[0045] (ii) Automatic compensation function for grinding head (based on precise measurement) 1) After grinding, the workpiece thickness is inspected. The PLC triggers the two laser sensors to take readings and calculates the current workpiece thickness. 2) The PLC compares the calculated actual thickness value with the target thickness value in the formula; 3) If the actual value is less than the target value, the PLC calculates the accurate compensation feed based on process parameters (such as grinding rate) and drives the servo drive to perform compensation grinding. 4) The system has a built-in wear counter that records the total compensation amount. When the total compensation amount exceeds the threshold, the HMI issues a warning to replace the grinding head.

[0046] 5) In the early stages, it is possible to determine how often the compensation feed rate needs to be modified through experiments, such as measuring once every hour.

[0047] (III) CNC Servo Automatic Feed Control 1) Execution unit: high-precision servo drive unit in conjunction with ball screw.

[0048] 2) Control: The PLC achieves absolute positioning via bus or pulse control. Feed rate and speed can be set on the HMI according to the recipe.

[0049] (iv) Formula-based management and parameter adjustment 1) HMI formulation parameters: In addition to the basic parameters, add laser sensor calibration parameters, compensation coefficient, measurement delay time (time to wait for water mist to dissipate), etc. 2) Manual mode: Provides independent jog control for all axes and allows real-time viewing of the measurement values ​​of the two laser sensors, facilitating equipment debugging and initial calibration.
