[0033] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0034] The first implementation method:

[0035] Figure 1-6 Shown is a complete denture symmetrical grinding device, comprising a workbench 1, on which a fixing mechanism and a grinding mechanism are installed;

[0036] The fixing mechanism includes a bracket 2 installed on the workbench 1, the top of the bracket 2 is fixedly connected with a clamp 3, and the grinding mechanism includes a fixed beam 4, a pair of electric guide rails are arranged on the fixed beam 4, and the movable ends of the pair of electric guide rails are both installed with synchronous cooperation arms;

[0037] The synchronous cooperation arm includes a fixed shell 5, a stepper motor is installed in the fixed shell 5, the power output end of the stepper motor is fixedly connected to the electric telescopic arm 6, the stepper motor is used to drive the electric telescopic arm 6 to rotate, the telescopic end of the electric telescopic arm 6 is fixedly connected to the mounting ring 7, the mounting ring 7 includes a fixed ring 71, an electric telescopic rod 72 is fixedly connected to the fixed ring 71, and a rotating motor 73 is connected between the fixed ring 71 and the telescopic end of the electric telescopic arm 6; the rotating motor 73 is used to drive the fixed ring 71 to rotate; the electric telescopic rod 72 is used to drive the grinding pen 8 to move

[0038] A grinding pen 8 is inserted into the fixed ring 71 , and the grinding pen 8 includes a shell 81 , a docking cover 82 is fixedly connected to the upper end of the shell 81 , a rotating shaft 83 is fixedly connected to the working end of the shell 81 , and a grinding head 9 is detachably mounted on the rotating shaft 83 .

[0039] A pair of receiving grooves are provided on the workbench 1, and a detection head 10 matching the rotating shaft 83 is placed in the receiving groove. A pressure sensing film is laid on the side end of the detection head 10, and a plurality of evenly distributed pressure detection nodes are arranged on the pressure sensing film.

[0040] A docking groove is provided at the top of the detection head 10, in which a docking joint electrically connected to the pressure sensing membrane is installed, and a docking interface matching the docking joint is fixedly connected to the bottom end of the rotating shaft 83.

[0041] A servo motor matching the rotating shaft 83 is installed in the housing 81. The rotating shaft 83 is rotatably connected to the housing 81 through a bearing. A docking shaft is movably inserted at the top of the rotating shaft 83. A slot matching the docking shaft is provided at the power output end of the servo motor. An electric push rod is installed in the housing 81. The power output end of the electric push rod is rotatably connected to the docking shaft. An electromagnet is installed at the bottom of the rotating shaft 83. A metal ring matching the electromagnet is installed in the docking slot. When the rotating shaft 83 is docked with the detection head 10, the electromagnet works and causes the metal ring to attract the electromagnet.

[0042] Optionally, after the detection head 10 is docked with the rotating shaft 83, the electric push rod can be controlled to work, thereby moving the docking shaft and separating the docking shaft from the slot at the power output end of the servo motor. At this time, the rotating shaft 83 can rotate freely, and when the detection head 10 rolls against the surface of the denture for detection, the rotating shaft 83 rotates accordingly.

[0043] The fixture 3 includes a movable seat 31 , to which a clamping plate 32 is connected via a lifting device, and a vertical guide rail matching the movable seat 31 is installed on the bracket 2 .

[0044] When the present solution is used for grinding, different positions of the denture are ground by adjusting the position of the grinding pen 8. During grinding, a pair of grinding mechanisms are controlled to operate successively to grind the symmetrical positions of the denture;

[0045] When the grinding mechanism for grinding is running, the set area of ​​the denture is ground according to the preset program and running track. During grinding, the position of the grinding pen 8 is adjusted by controlling the electric telescopic rod 72 to achieve fine adjustment of the grinding position of the grinding head 9;

[0046] After the grinding mechanism completes the grinding work, the grinding mechanism is controlled to reset, and then the position of the grinding pen 8 is adjusted to match the position of the detection head 10 placed on the workbench 1, and then the grinding pen 8 is driven off the shelf by the electric telescopic rod 72 until the rotating shaft 83 and the detection head 10 are stably docked, and then the detection head 10 is used to detect the grinding area. During the detection process, by comparing the difference between the pressure detection data and the set data when the detection head 10 moves along the set path, the detection point that exceeds the set pressure value is marked as a marked detection point;

[0047] If the number of marked detection points exceeds the set number, the system will alarm;

[0048] If not, the grinding mechanism is controlled to grind the marking detection point again; after grinding again, the detection head 10 is used for detection again; if the detection passes, the detection head 10 is reset;

[0049] Then the grinding mechanism is controlled to perform grinding work on the next set area, and another grinding mechanism is controlled to perform symmetrical grinding work on the symmetrical area of ​​the above-mentioned polished area. When performing symmetrical grinding work, the grinding mechanism performs targeted grinding on the symmetrical position points of the above-mentioned mark detection points (when determining the symmetrical position points, the midline of the full denture is used as the symmetry axis). During targeted grinding work, the control module controls the grinding pen 8 to work according to the set program.

[0050] This solution facilitates the precise grinding of full dentures and ensures the efficiency and accuracy of the grinding process. By using the synchronous cooperative arm, the grinding pen 8 can accurately grind the symmetrical parts of the denture, ensuring the symmetry and overall beauty of the denture. At the same time, the convenient disassembly and assembly of the detection head 10 can realize the rapid detection of the grinding effect after grinding, ensuring that the flatness and smoothness of the grinding area meet the predetermined standards; the equipment as a whole is convenient for grinding and testing, and it is easy to achieve good symmetry after the denture is polished, making the grinding work of the full denture more efficient and standardized.

[0051] Second implementation method:

[0052] Figure 7 As shown, it also includes an auxiliary grinding system, the auxiliary grinding system includes a processor, and the processor is connected to a control module, a data processing module, a data storage module and a monitoring module;

[0053] The control module is used to control the overall operation of the full denture symmetrical grinding equipment; it receives instructions from the processor, controls the start, stop and operation status of equipment such as the electric guide rail, stepper motor, electric telescopic rod 72, rotary motor 73, servo motor and lifting device, and ensures that the grinding mechanism works according to the preset program and trajectory; at the same time, the control module is also responsible for adjusting the position of the grinding pen 8, realizing fine-tuning of the grinding position of the grinding head 9, and controlling the resetting and docking of the grinding mechanism and the detection head 10.

[0054] The data processing module is used to process monitoring data and make judgments. When working, it receives pressure sensing data from the detection head 10; it receives data from the pressure detection node transmitted by the detection head 10 through the docking joint, compares and analyzes it, and calculates the difference between the actual pressure value and the set pressure value. When the number of marked detection points exceeds the set number, the data processing module will trigger a system alarm to prompt the operator to check and adjust.

[0055] The monitoring module is used to collect various monitoring data during the grinding process and the detection process. The monitoring data includes: running trajectory, pressure detection data and positioning data of the marking detection point; the monitoring module obtains the operating parameters of the equipment and the pressure data of the grinding area in real time by connecting the sensor and the detection head 10, and performs monitoring and analysis. When an abnormal situation is found, the monitoring module will issue an alarm message in time to remind the operator to deal with it. At the same time, the monitoring module can also record the key parameters and events in the grinding process to provide a basis for subsequent analysis and optimization.

[0056] The data storage module is used to store the positioning data and monitoring data of the grinding path and marking detection points. The data storage module can also provide historical data query function to facilitate operators to understand the operating status and grinding effect of the equipment.

[0057] The grinding path represents: when the control module controls the grinding mechanism to work, it controls the synchronous cooperation arm to adjust the movement of the grinding pen 8 so that the grinding head 9 moves along the set path, which is the motion control process of the grinding mechanism;

[0058] Through the coordinated work of various modules, the auxiliary grinding system of this embodiment can achieve precise control and rapid detection of the symmetrical grinding equipment of the full denture, improve the grinding accuracy and efficiency, and ensure the grinding quality.

[0059] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
