Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: Example

[0026] An internal gear machining equipment includes a frame 1, a workpiece positioning assembly 2 is arranged above the frame 1, a rotating mechanism 11 is mounted on the surface of the frame 1, the output shaft of the geared motor inside the rotating mechanism 11 is connected to the workpiece positioning assembly 2, a moving mechanism 12 is arranged above the workpiece positioning assembly 2, the moving mechanism 12 is mounted on one side surface of the frame 1, the moving end of the moving mechanism 12 is connected to a cutting tool 13 through a mounting base, and a cooling and lubrication mechanism 3 is mounted on the other side surface of the frame 1.

[0027] The tooling component 13 includes a tool mounting base, a tool spindle, and a machining tool. The tool mounting base is slidably mounted on one side of the frame 1 via a moving mechanism 12, and can move horizontally and vertically to adjust the relative position of the tool and the workpiece. The tool spindle is vertically mounted on the tool mounting base, with one end connected to the machining tool and the other end connected to the drive motor via a transmission device. The drive motor can drive the tool spindle to rotate at high speed.

[0028] A displacement sensor is installed on the tool machining part 13, and temperature sensors are installed on the tool spindle and the machining tool on the tool machining part 13 to detect the temperature of the tool.

[0029] The tool mounting base is slidably mounted on one side of the frame 1 via the moving mechanism 12, enabling precise adjustment of the relative position between the tool and the workpiece. The drive motor drives the tool spindle to rotate at high speed, thus causing the machining tool to operate at high speed and perform cutting operations on the workpiece. Furthermore, a displacement sensor is installed on the tool machining part 13 to monitor the tool's position in real time, allowing operators to adjust the tool position promptly and ensure machining accuracy. Temperature sensors are installed on the tool spindle and the machining tool on the tool machining part 13 to detect the tool's temperature. When the tool temperature is too high, measures can be taken to cool it down in time, preventing damage due to overheating, extending tool life, and ensuring machining quality. The moving mechanism 12 allows the tool machining part 13 to move horizontally and vertically, flexibly adjusting the relative position between the tool and the workpiece according to different machining requirements, improving machining accuracy and adaptability.

[0030] The workpiece positioning assembly 2 includes a mounting block 21, a positioning disk 22, an adjusting disk 23, a worm gear disk 24, a worm 25, a connecting rod 26, a rotating rod 27, a positioning pin 28, a limiting block 29, and a guide groove 210. The mounting block 21 is mounted on the output shaft end of the rotating mechanism 11. The positioning disk 22 is mounted above the mounting block 21. An adjusting disk 23 is located within the inner ring of the positioning disk 22. The central axis of the adjusting disk 23 is connected to the worm gear disk 24 located within the mounting block 21. The worm gear disk 24 meshes with the worm 25 located within the mounting block 21. A connecting rod 26 is inserted into a hole on the surface of the mounting block 21. One end of the connecting rod 26 is connected to the worm 25. The rod 25 is connected to the other end of the connecting rod 26, and a rotating rod 27 is provided at the other end. The three insertion holes on the surface of the positioning disk 22 are all provided with positioning pins 28. The surface of the adjusting disk 23 is provided with three guide grooves 210. Limiting blocks 29 slide in the guide grooves 210. The limiting blocks 29 are rotatably connected to one end of the positioning pins 28. By rotating the rotating rod 27, the worm 25 is driven to rotate. The worm 25 meshes with the worm wheel disk 24, thereby causing the adjusting disk 23 to rotate. When the adjusting disk 23 rotates, the positioning pins 28 are driven to move in the insertion holes of the positioning disk 22 through the guide grooves 210 and the limiting blocks 29, so as to achieve precise positioning of workpieces of different specifications.

[0031] The protruding end of the positioning pin 28 is equipped with a rubber pad 211, which can effectively prevent the workpiece from being scratched during the positioning process and increase the stability of positioning. Example

[0032] The cooling and lubrication mechanism 3 includes a condenser tank 31 and a liquid storage tank 33. The liquid storage tank 33 is installed on one side surface of the frame 1, and the condenser tank 31 is installed above the liquid storage tank 33. The inlet end of the condenser tank 31 is connected to the liquid storage tank 33, and the outlet end of the condenser tank 31 is connected to the liquid outlet nozzle installed at the cutting head of the tool processing part 13 via a connecting hose. The liquid guide pipe inside the condenser tank 31 adopts a corrugated pipe structure. Heat dissipation fins 32 are installed on both sides of the condenser tank 31 and are connected to the liquid guide pipe. The corrugated pipe structure inside the condenser tank 31 increases the contact area between the liquid and the air, improving the heat dissipation effect. The heat dissipation fins 32 installed on both sides of the condenser tank 31 and connected to the liquid guide pipe further enhance the heat dissipation capacity.

[0033] A fan 34 is installed above the condenser 31. The fan 34 is mounted on the surface of the frame 1. The fan 34 accelerates the airflow, which makes the coolant cool quickly in the condenser 31. Then, it is sprayed onto the tool processing area through the liquid outlet nozzle to cool and lubricate the tool, extend the tool service life, and ensure the processing quality.

[0034] Working principle: By setting the workpiece positioning component 2, precise positioning can be achieved for workpieces of different sizes. The rubber pad 211 at the protruding end of the positioning pin 28 can also prevent workpiece slippage and surface damage, improving the stability of processing and workpiece quality. The tool processing component 13, together with the moving mechanism 12, can flexibly adjust the tool position in multiple directions. Combined with the displacement sensor and temperature sensor, precise control of the processing process and real-time monitoring of the tool status are achieved, ensuring processing accuracy and tool life. The cooling and lubrication mechanism 3, through the synergistic action of components such as the condenser box 31, heat dissipation fins 32 and fan 34, efficiently cools the coolant, which can cool and lubricate the processing tool in a timely manner, effectively reducing the tool temperature, extending the tool life, and improving processing quality and production efficiency.
