A magnetic separator 41 is provided at the connecting position between the water collecting bucket 4 and the cooling box 6. The water outlet end of the water pump 42 is connected to an extended water outlet pipe 43, and the extended end of the water outlet pipe 43 is located above the electromagnetic holder 10. An ultrasonic water level detector 45 connected to the controller 2 is also provided on the cooling box 6.

[0028] A placement table 14 for placing a ring gauge and a stepper motor 50 are also provided on the base 1. A bottom plate 51 is provided at the output end of the stepper motor 50, and a second linear motor 52 is provided on the bottom plate 51. A horizontally extending connecting rod 53 is provided at the output end of the second linear motor 52, and a measuring device connected to the controller 2 is provided at the extending end of the connecting rod 53.

[0029] An outer cover 15 ( Figure 1 and Figure 2 An exhaust pipe 151 is provided on the outer cover 15, and an oil mist collector 16 is connected to the air outlet end of the exhaust pipe 151.

[0030] The controller 2 is provided with an inching button 20 ; the water pump 42 and the ultrasonic water level detector 45 are both connected to the controller 2 .

[0031] The operating principle of the utility model is as follows:

[0032] like Figures 1 to 3 As shown, during processing, the gear part is first placed on the electromagnetic holder 10. At this time, the inching button 20 is pressed on the controller 2 to manually rotate the grinding wheel and adjust the alignment and processing position of the inner hole of the gear part; then, the power supply of the electromagnetic holder 10 and the first linear motor 18 are turned on the controller 2, the grinding wheel is moved up and the electromagnetic holder 10 uses electromagnetic action to fix the gear part. The controller 2 is preferably a PLC controller. At this time, the inner hole of the gear part is connected to the through hole of the base 1, that is, the inner hole of the gear part is connected to the placement groove 12;

[0033] Next, the driving motor 17, the first linear motor 18, the second power motor 22 and the water pump in the coolant tank 13 are simultaneously turned on the controller 2, and the grinding wheel shaft 11 is synchronously driven to rotate, and the grinding wheel is also synchronously driven to move downward toward the gear part, and finally extends into the inner hole of the gear part, and the inner hole of the gear part is ground by the grinding wheel, and the coolant nozzle 131 discharges the coolant to the grinding position of the grinding wheel; the waste residue generated by the processing falls onto the conveyor belt 32 through the through hole on the base 1, and since the conveyor belt 32 is provided with a plurality of filter holes 321 (such as Figure 3 As shown in the state, the coolant can be quickly separated from the waste residue and flow into the water collecting bucket 4, while the waste residue is conveyed by the conveyor belt 32 to the waste box 5 for collection.

[0034] During this process, the coolant in the water collecting barrel 4 will flow into the connected cooling box 6. Since metal waste slag will be mixed in the used coolant, in order to prevent the recycling of the coolant from being mixed with metal particles and thus affecting the grinding quality of the grinding wheel, a magnetic separator 41 is provided at the connection position between the water collecting barrel 4 and the cooling box 6. As the processing proceeds, the temperature of the coolant will increase. At this time, it is necessary to turn on the power of the cooling box 6 on the controller 2 and refrigerate the coolant. When the coolant reaches the use temperature, turn off the power of the cooling box 6. Repeat this operation to maintain the use temperature of the coolant.

[0035] During use, as the coolant accumulates in the cooling box 6, when the ultrasonic water level detector 45 measures the highest water level, the controller 2 turns off the water pump of the coolant tank 13 and turns on the water pump 42 to pump the coolant in the cooling box 6 to the water outlet pipe 43 for discharge. Since the water outlet end of the water outlet pipe 43 is located above the electromagnetic holder 10, that is, above the gear part, the grinding wheel has extended into the inner hole of the gear part, so that the circulating coolant can continue to cool the grinding position of the grinding wheel, saving production water.

[0036] After processing, remove the ring gauge from the placement table 14 to detect the inner hole size. If the ring gauge detection is unqualified, take out the ring gauge, and start the second linear motor 52 on the controller 2 to synchronously drive the connecting rod 53 and the detection device to move up, and then start the stepper motor 50 to drive the base plate 51 to rotate in the horizontal direction, and stop moving when the detection device is located directly above the gear part. At this time, according to the type and configuration of the detection device, if it is an infrared detector, it is necessary to start the second linear motor 52 again to drive the connecting rod 53 and the synchronous detection device to move down, and make the detection position of the detection device extend into the inner hole of the gear part; if it is an image detector, the aperture can be measured directly above the gear part, and the relevant parameter settings used for detection should be entered into the controller 2 before use for corresponding use, which will not be repeated here.

[0037] After all the waste residues on the conveyor belt 32 have fallen off, turn off the second power motor 22, and then turn on the first power motor 21 to make the conveyor belt 32 move back in the opposite direction. At this time, the coolant in the water outlet pipe 43 directly flushes the conveyor belt 32 from the through hole on the base 1, which can play a cleaning role. In order to facilitate the adjustment of the flushing direction, the drain pipe 43 should adopt a threaded pipe; if the conveyor belt 32 needs to be replaced, remove one end of the conveyor belt 32 connected and fixed by the Velcro 7 on the driving shaft 30, and then remove the rotating shaft 31 to remove the conveyor belt 32 as a whole, and then replace it with the rotating shaft 31 with a new conveyor belt 32, and bond one end of the conveyor belt 32 to the driving shaft 30 with the Velcro 7 for continued use.

[0038] In addition, since the coolant contains organic oil components, during the cooling and grinding process, water mist containing oil will be formed under the influence of the high-speed rotation of the grinding wheel and diffuse in the processing area inside the outer cover 15. An exhaust pipe 151 that can discharge water mist particles is provided, and the air outlet end of the exhaust pipe 151 is connected to an oil mist collector 16 to ensure the air quality of the production and processing area.

[0039] In order to prevent electromagnetic effects from affecting the normal use of the motors, magnetic insulation pads (not shown) are provided on the outer side walls of each motor and at the installation positions of the motors on the base 1 .
