The working principle of the embodiment of the application is as follows:

the vibration disc 21 is started, the valve seat in the vibration disc 21 moves to the space between the four baffle plates 222 and the bottom plate 221 through the feeding rail 23, so that the valve seats are overlapped together, the feeding cylinder 24 is started to drive the feeding push block 25 to move to push the valve seat to the clamping grooves 27 of the two clamping plates, feeding of the valve seat is completed, then the feeding push block 25 moves back to the original position, and the valve seat moves downwards to the position of the previous valve seat under the action of gravity, so that feeding is continued.

The rotating motor 32 is started to drive the second gear 33 to rotate, the second gear 33 rotates the first gear 31 and the rotating shaft 151 to rotate, the rotating shaft 151 rotates to drive the supporting plate 16 to rotate, the supporting plate 16 rotates to extrude the guide angle 38 so that the locking column 37 is separated from the clamping groove 162, and after the supporting plate 16 rotates 180 degrees, the rotating motor 32 stops rotating, so that the locking column 37 is clamped and installed on the clamping groove 162, the clamping pieces 26 on two sides of the rotating plate 161 are switched, the valve seat rotates to the side close to the tool apron 121, and the feeding cylinder 24 can start to feed the valve seat to the clamping grooves 27 of two empty clamping plates.

First cylinder 13 starts to drive first slide 11 and removes, second cylinder 14 starts to drive second slide 12 and blade holder 121 and removes, blade holder 121 removes and drives drill bit 122 and removes, the motor drives drill bit 122 simultaneously and rotates, drill bit 122 removes and drives the pipe 62 that slides and remove, consequently drill bit 122 with slide pipe 62 contradict on the disk seat together, drill bit 122 drills to the disk seat, drill bit 122 removes and drives the pipe 62 that slides and first solid fixed ring 631 removes, first solid fixed ring 631 removes and extrudes fixed spring 633.

When the dust suction fan 644 is started, the chips generated by the processing of the drill 122 are moved to the dust suction frame 643 through the first dust suction pipe 642 for collection, so that the probability that the chips are sputtered to the periphery in the processing process of the workpiece is reduced, and the environmental quality around the drilling machine is improved; and gas loops through dust hood 645 and second dust absorption pipe 646 and gets into sliding pipe 62, and gas blows and goes up to cool down drill bit 122 on the drill bit 122, and simultaneously cooling pump 73 starts, and the coolant liquid gets into the cooling chamber through feed liquor pipe 74 and cools down the gas in second dust absorption pipe 646, and the coolant liquid flows back in cooling tank 71 through drain pipe 75 to this has reduced the probability that drill bit 122 high temperature and damage, has improved the life-span of drill bit 122, has also improved the processingquality of drilling machine simultaneously.

After the valve seat is machined, the sliding pipe 62 moves back to the original position under the action of the fixed spring 633; the piston rod of the blanking cylinder 41 is started to push the valve seat to move to the first guide rail 421, then the valve seat slides to the second guide rail 422, then the valve seat falls downwards to the separation filter frame 53, the vibration motor 57 is started to drive the eccentric wheel 56 to rotate, the eccentric wheel 56 rotates to drive the separation filter frame 53 to vibrate up and down, therefore, the fragments on the valve seat pass through the separation filter frame 53 to fall into the material receiving box 433 to be collected, so that the fragments and the valve seat are separated, the influence of the fragments on the quality of the valve seat and the subsequent processing is reduced, and the quality of the valve seat is improved.

After separation filter frame 53 and material receiving box 433 filled up simultaneously, pulling apron 52 will separate filter frame 53 and dismantle and clear up, clear up the back, will separate filter frame 53 and install on the hole 431 that slides, and pulling material receiving box 433 takes off and clear up, clear up the back, install material receiving box 433 on through-hole 432 to this has improved the collection effect of separation filter frame 53 and material receiving box 433.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
