The main shaft is rotatably arranged on the spindle box, the tool breaking mechanism is arranged in the main shaft, and the tool breaking mechanism can be directly arranged according to the structure of the existing numerical control machining center. The pawl is arranged in the taper hole of the bottom of the main shaft, the pawl is clamped and released through the cooperation of the pull rod, the disc spring and the tool breaking hydraulic cylinder on the top of the main shaft, the pawl is matched with the top pull pin of the tool handle 107, the synchronous belt pulley is arranged on the top of the main shaft, the main shaft rotating servo motor is arranged on the top of the spindle box, the synchronous belt pulley is arranged on the output shaft of the main shaft rotating servo motor, and the transmission is realized through the synchronous belt and the synchronous belt pulley arranged on the top of the main shaft. The protective cover is arranged on the top of the spindle box for protection, the tool handle 107 is arranged on the bottom of the main shaft, and the polishing tool is arranged on the bottom of the tool handle 107.

[0024] Then, the first drive mechanism 108 and the second drive mechanism 109 both adopt the driving servo motor with the brake mechanism and the encoder as the power source, and the driving servo motor is electrically connected with the polishing machine body 101. The driving servo motor with the brake mechanism and the encoder can realize the stop locking shaft and the position control.

[0025] Finally, the manual tool changing button 110 is arranged on the front side of the protective cover of the spindle box of the polishing machine body 101, and the manual tool changing button 110 is electrically connected with the polishing machine body 101. The manual tool changing button 110 is used for manually changing the tool, and after being pressed, the action of the tool breaking hydraulic cylinder of the tool breaking mechanism on the top of the polishing machine body 101 can be manually controlled, so that the tool can be manually installed or removed.

[0026] To address the problem of traditional grinding equipment lacking an automatic tool changer, requiring manual tool replacement, resulting in low automation and inconvenience, this invention addresses the following: First, multiple tool holders 107 are pre-inserted into multiple tool sleeves 105, one-to-one. During insertion, the positioning block on the tool holder 107 mates with the positioning groove on the tool sleeve 105, leaving a margin at the top for engagement with the positioning groove on the spindle of the grinding machine body 101. When installing the tool holder 107 into the tool sleeve 105, an empty space is left, allowing the tool holder 107 to be directly mounted on the spindle of the grinding machine body 101. Then, the first drive mechanism 108 and the second drive mechanism 109 work together to enable the spindle of the grinding machine body 101 to move left and right or vertically, thus moving the tool on its spindle for grinding. When tool replacement is needed, the grinding machine body 101 automatically moves its spindle box above the tool change point. Then, the cutter head servo motor 103 actuates, driving the rotating cutter head 104 to rotate. First, the empty tool holder 105 is positioned to the tool receiving point. At this time, the grinding machine body 101 automatically orients the spindle and moves downwards, inserting the tool holder 107 on the spindle into the empty tool holder 105. Then, the tool release mechanism on the spindle actuates to release the tool, while the spindle moves upwards to the avoidance point to release the tool. Then, the cutter head servo motor 103 actuates, driving the rotating cutter head 104 to rotate, and the tool that needs further... The tool holder 107 of the tool to be changed rotates to the tool changing point. The grinding machine body 101 automatically orients the spindle and moves downward to insert the tool holder 107 into the spindle. At the same time, the tool clamping mechanism on the spindle clamps the tool holder 107. Finally, the spindle moves upward to complete the tool change. The grinding machine body 101 can then operate automatically for processing. This solves the problem that traditional grinding equipment does not have an automatic tool changing mechanism, which requires manual tool changing, resulting in low automation and inconvenience in processing and use.
