Grinding wheel grinding is also difficult to ensure the uniformity of the workpiece surface due to the simple equipment, and the quality of the finished product fluctuates greatly.

[0020] The working principle of the fast-adjusting grinding processing equipment for multi-stage pump workpiece processing disclosed in the present invention is as follows: place the multi-stage pump workpiece to be ground on the placement table 138 (select a placement table 138 of a suitable height according to the size. If the workpiece is light, it is necessary to tie the workpiece to the placement table 138 with a strap), and then inject grinding sand into the storage pool 101, or inject grinding sand into the storage pool 101 first, and then place the multi-stage pump workpiece. Then control the adjustment motor 103, and the output shaft of the adjustment motor 103 drives the adjustment magnet 105 to swing through the adjustment magnet bracket 104. The adjustment magnet 105 constrains the adjustment swing magnetic suction frame 107 through magnetic force, so that the adjustment swing magnetic suction frame 107 moves synchronously with the adjustment magnet 105. The adjustment swing magnetic suction frame 107 will drive the injection chamber 110 and the injection nozzle 113 to move synchronously through the extension rod frame 106. At this time, the grinding sand is adjusted on the surface of different positions of the workpiece for grinding. Specifically, the driving boost motor 118 is started to drive the boost The output shaft of the motor 118 drives the impeller 115 to rotate. After the impeller 115 rotates, the grinding sand in the storage pool 101 is sucked into the driving booster chamber 114 (the grinding sand needs to completely submerge the driving booster chamber 114). Then, the rotation of the impeller 115 also drives the grinding sand to rotate, thereby driving the grinding sand to flow from the driving booster chamber 114 to the inside of the injection chamber 110 under the action of centrifugal force, and then ejected through the injection nozzle 113, shooting the grinding sand toward the surface of the workpiece, so that the grinding sand rubs against the surface of the workpiece, thereby achieving the purpose of grinding processing. When it is necessary to clean the grinding sand inside the injection nozzle 113, the magnetic pole direction of the electromagnet 108 is controlled so that the electromagnet 108 attracts or repels the permanent magnet plate 111 (attraction is required when the injection nozzle 113 sprays grinding sand). When the permanent magnet plate 111 is repelled, the permanent magnet plate 111 will drive all the inserted cleaning pins 112 to insert into the injection nozzle 113, thereby ejecting the grinding sand blocked inside the injection nozzle 113, and then reverse the magnetic pole direction of the electromagnet 108 again to control the inserted cleaning pins 112 to be withdrawn from the injection nozzle 113.When it is necessary to grind the other side of the workpiece, the flipping drive motor 130 is controlled, and the output shaft of the flipping drive motor 130 drives the flipping drive gear 131 to rotate, and the flipping drive gear 131 drives the flipping drive toothed disc 133 to rotate, and the flipping drive toothed disc 133 drives the flipping drive screw 134 to move axially, and then the flipping drive screw 134 drives the flipping piston 136 to slide in the flipping extrusion hydraulic cylinder 135, so that the flipping piston 136 squeezes the air inside the flipping extrusion hydraulic cylinder 135. The pressure inside the turning and squeezing hydraulic cylinder 135 increases, and the pressure is transmitted to the three-way pipe 125 through the hydraulic pipe 123. The three-way pipe 125 transmits the pressure to the turning hydraulic cylinder 122 and the clamping hydraulic cylinder 124. At this time, the telescopic rod of the turning hydraulic cylinder 122 needs to overcome the magnetic attraction of the moving magnetic block 127 and the fixed magnetic block 128 in order to retract. Therefore, most of the pressure will be transmitted to the clamping hydraulic cylinder 124, and the telescopic rod of the clamping hydraulic cylinder 124 will drive the workpiece clamping head 137 moves toward the workpiece (the telescopic rod and telescopic tube of the clamping hydraulic cylinder 124 cannot rotate relative to each other), and then when the workpiece clamping head 137 contacts the surface of the workpiece, the workpiece clamping head 137 cannot move. At this time, the telescopic rod of the clamping hydraulic cylinder 124 cannot move, which will cause the pressure inside the telescopic tube of the clamping hydraulic cylinder 124 to be unable to be released. At this time, most of the pressure will be transmitted to the inside of the flipping hydraulic cylinder 122, and then the pressure inside the flipping hydraulic cylinder 122 will increase. At this time, the magnetic attraction between the moving magnetic block 127 and the fixed magnetic block 128 can be overcome, causing the moving magnetic block 127 to separate from the fixed magnetic block 128, and then drive the flipping swing arm 126 to swing, and the swing of the flipping swing arm 126 drives the clamping hydraulic cylinder 124 to swing, and the swing of the clamping hydraulic cylinder 124 drives the workpiece to swing (depending on the shape of the workpiece, some non-rotating workpieces cannot rotate, at this time, it is necessary to replace the workpiece clamping head 137 with a suitable fixture, that is, to make the workpiece not in the axial position of the workpiece clamping head 137, and then it can be flipped). When resetting is required, it is only necessary to control the output shaft of the flipping driving motor 130 to rotate in the reverse direction.
