A door 13 is installed on the side wall of the processing chamber 11. An observation window is fixed on the door 13. There are four sets of doors 13, distributed on the four side walls of the processing chamber 11. The doors 13 are rotatably connected to the processing chamber 11 and are equipped with mechanical locks. The placement of the storage door 13 and the observation window facilitates the observation and adjustment of the internal situation.

[0022] The conveying mechanism 2 is used to transport the thermos cup body workpiece, the clamping mechanism 3 fixes the workpiece, and the grinding mechanism 4 grinds the mouth of the thermos cup workpiece.

[0023] Furthermore, the transmission mechanism 2 is used to transport the workpiece, including: Mounting frame 21 is fixedly mounted on frame 1, with both ends penetrating processing chamber 11, and is divided into loading end and unloading end.

An annular conveyor belt 22 is arranged around the mounting frame 21 and maintains contact with the drive roller and the driven roller; A baffle 23 is detachably mounted on the mounting frame 21 and is used to block the conveyed workpiece. A first infrared sensor 24 is fixedly connected to the baffle 23. The first infrared sensor 24 is electrically connected to the central control element. The baffle 23 is located at the unloading end. When the workpiece is transferred to the first infrared sensor 24, feedback is sent to the central control element, which activates the buzzer and warning light to indicate that the workpiece grinding is complete. It also includes two sets of spaced-apart limiting components 25 for limiting the conveying of workpieces. Each set of limiting components 25 includes at least two support rods 2501, each support rod 2501 is threaded with a screw 2502, one end of the screw 2502 is rotatably provided with a limiting plate 2503, and the other end of the screw 2502 is fixedly provided with a knob. The support rod 2501 is fixed to the frame 1; The screw 2502 is driven to move by the control knob. The movement of the screw 2502 drives the limiting plate 2503 to move, thereby limiting the movement of the workpieces conveyed on the annular conveyor belt 22 and preventing the workpieces from tipping over during the conveying process.

A lead screw 3206 is rotatably mounted on a top plate 3102. A handwheel is fixedly mounted on the top of the lead screw 3206. A slider 3207 is threaded onto the lead screw 3206. The slider 3207 is fixedly connected to the base plate 3201. When the movable clamping assembly 32 is adjusted, the screw 3206 is rotated by rotating the handwheel. The rotation of the screw 3206 causes the slider 3207 on it to move. The slider 3207 causes the base plate 3201 to move, which in turn causes the first support plate 3203 to move. The first support plate 3203 causes the first electric push rod 3204 to move, so as to realize the adjustment of the first clamping block 3205. The fixed clamp assembly 33 includes: The second support plate 3301 is fixedly connected to the positioning frame 31; The second electric push rod 3302 is fixedly installed on the second support plate 3301.

The second infrared sensor 3304 is electrically connected to the central control element.

[0025] Furthermore, the grinding mechanism 4 is used to grind the workpiece, and includes an X-axis translation component 41, a Y-axis translation component 42, a Z-axis lifting component 43, and a grinding block 44; The X-axis translation component 41 includes: The first electric slide rail 4101 is fixed on the support frame 12; The first electric slide table 4102 is coupled to the first electric slide rail 4101 via a sliding pair; The second servo motor 4103 is located at one end of the first electric slide rail 4101; The Y-axis translation component 42 includes: The second electric slide rail 4201 is fixed on the first electric slide table 4102; The second electric slide 4202 is coupled to the second electric slide rail 4201 via a sliding pair; The third servo motor 4203 is located at one end of the second electric slide rail 4201; The second electric slide rail 4201 is equipped with a limiting slider for cooperating with the limiting slide rail mounted on the support frame 13; The Z-axis lifting assembly 43 includes: The third electric slide rail 4301 is fixed on the second electric slide table 4202; The third electric slide 4302 is coupled to the third electric slide rail 4301 via a sliding pair; The fourth servo motor 4303 is located at one end of the third electric slide rail 4301; Also includes: Fixed compartment 45 is fixed on the third electric slide 4302; The fifth servo motor 46 is fixed inside the fixed chamber 45, and the output end of the fifth servo motor 46 is fixedly connected to the grinding block 44.

[0026] Furthermore, the central control element is used to receive signal feedback from the first infrared sensor 24 and the second infrared sensor 3304. When the second infrared sensor 3304 detects that the workpiece on the transmission mechanism 2 has moved to that location, it sends feedback to the central control element, which then issues a stop command to the first servo motor and commands to the clamping mechanism 3 and the grinding mechanism 4.

[0027] A two-phase flow grinding machine, the working principle of which is as follows: The workpiece is fed from the loading end by a robotic arm or a worker and transported by the circular conveyor belt 22. When the workpiece is transported to the second infrared sensor 3304, the central control element stops the transmission mechanism 2 and starts the first electric push rod 3204 and the second electric push rod 3302, which in turn drives the first clamping block 3205 and the second clamping block 3303 to clamp the workpiece. Then, the central control element issues a command to the grinding mechanism 4, which drives the grinding block to grind the mouth of the thermos cup workpiece through the second, third, fourth and fifth servo motors 46. After the grinding is completed, the clamping of the workpiece is released through the coordination of the central control element, and the transmission mechanism 2 is restarted.
