The working principle is as follows: an operator places a valve to be processed at the position of the adsorption head 31 above the fixed cylinder 29, if the valve is light in volume, the adsorption head 31 can be adsorbed with the surface of the valve, if the valve is heavy in volume, the adsorption head 31 can be pressed downwards by the valve, so that the adsorption telescopic rod 36 arranged below the adsorption head 31 is pushed to move downwards, so that the linkage rod 43 arranged below the adsorption telescopic rod 36 is pushed to move downwards, so that the pressing block 54 arranged below the linkage rod 43 is pushed to move downwards, so that the pressing block air inlet 56 arranged at one side of the pressing block 54 is pushed to be contacted with the air supply hole 38, at the moment, the air supply hole 38 starts to supply air, so that the air is discharged into the air inlet pipeline 55 through the pressing block air inlet 56 connected with the air inlet pipeline, at the moment, the air entering the air inlet pipeline 55 enters the fixed pipeline 60 at the center of the inner fixed platform 30 through the inner clamping base 45, the gas entering the fixed pipeline 60 can jack up the inner fixed platform 30 upwards, so that the upper end face of the inner fixed platform 30 is in contact with the surface of the valve, at the moment, the valve is sucked by the adsorption head 31, the inner fixed platform 30 cannot be continuously pushed up, at the moment, the gas entering the fixed pipeline 60 can enter the inner clamping base 61 of the upper end face of the inner fixed platform 30, the inner clamping rod 32 arranged in the inner clamping base 61 is pushed to move outwards, the plane contact plate 62 arranged outside the inner clamping rod 32 is pushed to move outwards, at the moment, if the bottom of the valve body is in a solid state, the plane contact plate 62 and the inner fixed platform 30 can play a role in supporting the valve body together, and therefore the valve body can be stably processed. If the bottom of the valve body is in a cylindrical inner hole shape, at this time, the adsorption head 31 may not be completely attached to the valve body, but the adsorption head 31 still moves downward due to gravity, at this time, the inner clamping rod 32 continuously moves outward until the outer end face of the inner clamping rod 32 and the plane contact plate 62 contacts with the wall surface of the cylindrical inner hole, so that the clamping effect on the inner wall surface is formed, and the clamping reliability is ensured.

When the inner clamping rod 32 and the adsorption head 31 fix the bottom of the valve body, the first cylinder 13 and the second cylinder 14 are started, the output ends of the first cylinder 13 and the second cylinder 14 push the first push rod 16 and the second push rod 17 to move inwards, so as to push the first push block 49 arranged on one side of the first push rod 16 and the second push block 50 arranged on one side of the second push rod 17 to move inwards, so as to push the first clamping plate 11 arranged on one side of the first push block 49 and the second clamping plate 12 arranged on one side of the second push block 50 to move inwards, so as to push the clamping chamber 15 arranged on the second clamping plate 12 and the first cylinder 13 to move inwards, so as to push the connecting plate 26 arranged on one side of the clamping chamber 15 to move inwards, so as to push the flexible rotating wire wheel 27 arranged on the connecting plate 26 to move inwards until the flexible rotating wire 27 is in contact with the valve body arranged on the fixed rotating rod 29, so that the flexible rotating wire wheel 27 is pressed to move inwards, so as to push the connecting plate 26 arranged on the surface of the flexible rotating wire wheel 27 to push the connecting plate 27 to move inwards, so as to push the clamping rod 25 arranged on the outer side of the clamping chamber 15, and the clamping chamber 15, so as to push the clamping rod 25 arranged on the clamping chamber 25, so as to gradually contact with the clamping rod 25, and the clamping rod 25 arranged on the outer side of the clamping chamber 15, so as to be pressed by the clamping rod, and the clamping rod 25, so as to be pressed by the clamping cylinder 25, and the clamping chamber 25, and the clamping rod 25, and the clamping chamber 25 arranged on the clamping rod 25, therefore, an enclosing ring is formed outside the valve body to fix the valve body, and meanwhile, the flexible element of the flexible rotating wire wheel 27 can not crush the surface of the valve body in the enclosing and fixing process, so that the crushed surface of the processed valve body is effectively avoided. Meanwhile, the design can also avoid secondary fixation when the valve body is light and the adsorption head 31 does not slide downwards, so that the inner clamping rod 32 and the plane contact plate 62 are not fixed, and the clamping effect is guaranteed.

After the valve is fixed, the valve can be processed.

After the processing is finished, the first cylinder 13 and the second cylinder 14 return to the original positions respectively, at this time, the air supply hole 38 stops supplying air, at this time, the inner clamping rod 32 in the inner clamping base 61 returns to the original position under the action of the fourth spring 64 arranged at the bottom due to the loss of pressure, and at this time, the operator can take the valve body.

When the valve body is taken, the adsorption head 31 and the adsorption telescopic rod 36 can return under the action of the first spring 44 arranged at the bottom due to pressure loss, so that the pressing block 54 arranged at the bottom of the first spring 44 is driven to move outwards, the pressing block air inlet 56 on one side of the pressing block 54 is staggered with the air supply hole 38, and the air inlet pipeline 55 is in a sealed state at the moment.

At this time, the air supply hole 38 starts to supply air, so that the air is infused into the air bin 42, the air entering the air bin 42 enters the air duct 52 through the end face of the air duct 52 at the bottom, a part of the air entering the air duct 52 is sprayed out through the first dust removal port 53 arranged at the other end, so that the iron chips and the wastewater falling outside the fixed cylinder 29 in the processing process are blown to the sewage discharge port 41 and then discharged out through the sewage discharge port 41. The other part of the gas entering the air duct 52 enters the second dust removing duct 59 on one side, and then is sprayed outwards through the second dust removing nozzle 66 arranged at the top of the second dust removing duct 59, so as to remove the dirt on the upper end surface of the fixed cylinder 29, in this relation, the fixed cylinder 29 and the first dust removing port 53 continuously spray air, so as to remove the iron filings and other dirt, and the air is sprayed until the next valve body is placed on the adsorption head 31, so as to remove the dust on the bottom of the valve body, thereby ensuring the clamping effect of the bottom, when the valve body is placed on the adsorption head 31, the air inlet 56 of the pressing block 54 on one side contacts the air supply hole 38, the gas in the air supply hole 38 cannot enter the air chamber 42, and at this time, the fixed cylinder 29 and the first dust removing port 53 stop spraying air.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
