The polishing wheel is driven by a driving motor to rotate at high speed, and the fan is driven to rotate, one side of the fan facing the cylinder inlet. The metal dust generated when the polishing wheel grinds the parts is instantly rolled into the cylinder by the airflow formed by the rotation of the fan. The filter assembly in the cylinder screens the metal dust to make it accumulate on the windward side of the filter assembly. When the metal dust on one side of the filter assembly accumulates more and more, it causes blockage of the filter assembly, so that the airflow cannot pass through the filter screen. Under the push of the airflow, the filter assembly moves, so that the fixed ring opens the chip removal opening and blocks the air outlet. At this time, the airflow carrying the metal dust enters the dust collecting box through the chip removal opening for accumulation. When the metal dust blocked on one side of the filter assembly enters the dust collecting box, the filter assembly restores the ventilation state and is reset under the action of the spring. The airflow flows into the air guide pipe from the air outlet, solving the problem that the metal dust generated when polishing titanium alloy, magnesium alloy and other metal plates invades the joints and guide rails of the robot, thereby accelerating the wear of the precision parts.

[0015] 2. The airflow from the air outlet enters the air guide pipe, and then flows into the air cooling pipe. The air cooling pipe and the rotating cylinder clamp and fix the workpiece being polished. The airflow in the air cooling pipe continuously exists, carrying away the heat generated during polishing, avoiding the problem that the heat generated during processing causes the workpiece to locally expand, and the workpiece shrinks after cooling, causing the workpiece to deform, thereby improving the quality of workpiece processing.

[0027] With reference to Figure 5 And Figure 6 The dust collecting assembly 3 comprises a cylinder 301, one end of the top of the cylinder 301 is fixedly connected with a dust collecting box 302, one end of the top of the cylinder 301 is fixedly connected with a wind guide pipe 303, and the wind guide pipe 303 is on the same side of the dust collecting box 302, one end of the wind guide pipe 303 is fixedly connected with a wind cooling pipe 105; The inner side of the cylinder 301 is slidably sleeved with a filter assembly 304, the inner side of one end of the cylinder 301 is fixedly sleeved with a sealing sheet, one side of the sealing sheet is fixedly connected with a spring, one end of the spring is fixedly connected to one side of the filter assembly 304, the top of one end of the cylinder 301 is provided with a chip outlet, the bottom of one end of the cylinder 301 is provided with an air outlet, the size of the chip outlet is the same as that of the air outlet, the vertical distance between the chip outlet and the air outlet is the same as the thickness of the filter assembly 304, the chip outlet is communicated with the dust collecting box 302, and the air outlet is communicated with the wind guide pipe 303.

[0028] Need to be specifically supplemented in this embodiment is that in the original state, the filter assembly 304 is located inside the cylinder 301 and blocks the chip outlet, at this time, the airflow flows through the cylinder 301 and is discharged from the air outlet, when the filter assembly 304 is blocked due to too much metal dust accumulation, the airflow cannot pass through the filter assembly 304, and thus the filter assembly 304 is pushed to move, the filter assembly 304 blocks the air outlet and opens the chip outlet, the airflow is discharged from the chip outlet and carries away the blocked metal dust, when the metal dust is blown away and the filter assembly 304 can flow, the filter assembly 304 is reset under the action of the spring and returns to the original state.

[0029] The polishing wheel is driven to rotate at high speed by the driving motor 203, the fan 205 is driven to rotate, one side of the fan 205 is opposite to the inlet of the cylinder 301, the metal dust generated when the polishing wheel 204 grinds the parts is instantly rolled into the cylinder 301 by the airflow formed by the rotation of the fan 205, the filter assembly 304 in the cylinder 301 screens the metal dust to make it gather on the windward side of the filter assembly 304, when the metal dust on one side of the filter assembly 304 gathers more and more, the filter assembly 304 is blocked, the airflow cannot pass through the filter assembly 304, the filter assembly 304 moves under the push of the airflow, the filter assembly 304 opens the chip outlet and blocks the air outlet, at this time, the airflow carrying the metal dust enters the dust collecting box through the chip outlet, when the metal dust blocked on one side of the filter assembly 304 enters the dust collecting box 302, the filter assembly 304 restores the ventilation state and resets under the action of the spring, the airflow flows into the air duct 303 from the air outlet, which solves the problem that the metal dust generated when the titanium alloy, magnesium alloy and other metal plates are ground will invade the joints and guide rails of the robot, thereby accelerating the wear of the precision parts.

[0031] It needs to be particularly supplemented in the embodiment that the filter screen 3042 allows the airflow to pass through and intercepts the metal dust on one side of the filter screen. The airflow enters the air duct 303 from the air outlet and then flows into the air cooling pipeline 105, the air cooling pipeline 105 and the rotating drum 1042 clamp and fix the workpiece to be ground, the airflow in the air cooling pipeline 105 continuously exists and carries away the heat generated during grinding, which avoids the problem that the heat generated during the machining process causes the local expansion of the workpiece, and the shrinkage of the workpiece after cooling causes the deformation of the workpiece, thereby improving the quality of the workpiece machining.

[0032] The working principle of the present application is as follows: the driving motor 203 drives the polishing wheel to rotate at high speed, and drives the fan 205 to rotate. The fan 205 is opposite to the inlet of the cylinder 301. The metal dust generated when the polishing wheel 204 grinds the parts is instantly rolled into the cylinder 301 by the airflow formed by the rotation of the fan 205. The filter assembly 304 in the cylinder 301 screens the metal dust to make it accumulate on the windward side of the filter assembly 304. When the metal dust on one side of the filter assembly 304 accumulates more and more, it causes blockage of the filter assembly 304, so that the airflow cannot pass through the filter assembly 304. Under the push of the airflow, the filter assembly 304 moves, so that the filter assembly 304 opens the chip outlet and blocks the air outlet. At this time, the airflow carrying the metal dust enters the dust collecting box through the chip outlet. When the metal dust blocked on one side of the filter assembly 304 enters the dust collecting box 302, the filter assembly 304 restores the ventilation state and resets under the action of the spring. The airflow flows into the air guide pipe 303 from the air outlet, solving the problem that the metal dust generated when polishing titanium alloy, magnesium alloy and other metal plates invades the joints and guide rails of the robot, thereby accelerating the wear of the precision parts. The airflow from the air outlet enters the air guide pipe 303 and then flows into the air cooling pipe 105. The air cooling pipe 105 and the rotating drum 1042 clamp and fix the workpiece to be polished. The airflow in the air cooling pipe 105 continuously exists, carrying away the heat generated during polishing, thereby avoiding the problem that the heat generated during the machining process causes the workpiece to locally expand, and the workpiece shrinks after cooling, causing the workpiece to deform, thereby improving the quality of the workpiece machining.
