Meanwhile, the second sliding block 106 drives the sealing plug 96 to move towards one side close to the third motor 103 through the U-shaped connecting rod 107, so that the pressure between the sealing plug 96 and the side wall of the recycling box 95 close to one side of the collecting box 91 is reduced, the supernatant (cooling liquid) in the collecting box 91 enters the recycling box 95 through the connecting pipe 97, and the precipitate 911 is retained at the bottom of the collecting box 91.

The implementation principle of the embodiment is as follows: when grinding the work piece, the work piece 3 of treating to process is carried out the centre gripping to staff's accessible first centre gripping subassembly 21, treat subsequently through grinding wheel subassembly 4 treat process work piece 3 carry out grinding can, under the mating reaction of first protection network 61 and second protection network 62, concentrate on the cylinder processing space by the piece that produces in the work piece course of working to the condition that the piece that has avoided the grinding in-process to produce splashes everywhere, thereby has reduced the clearance degree of difficulty of staff to the piece.

Before the workpiece 3 to be processed is ground, the worker only needs to open the second protective net 62, and simultaneously connects one end of the workpiece 3 to be processed with the first chuck 213, and then adjusts the first cylinder 222, so that the piston rod of the first cylinder 222 extends until the second chuck 224 abuts against one end of the workpiece 3 to be processed, which is far away from the first chuck 213, and the workpiece 3 to be processed can be fixed, and the workpiece 3 to be processed can be processed. After the workpiece 3 to be processed is fixed, the worker only needs to close the first protective net 61 and the second protective net 62, and simultaneously clamps the elastic positioning element 74 between the vertical portion of the L-shaped fixture block 73 and the second protective net 62, so as to fix the first protective net 61 and the second protective net 62 well. When the workpiece 3 to be machined is ground, the worker only needs to turn on the second motor 42, and the second motor 42 drives the small grinding wheel 44 fixed to the output shaft of the second motor to rotate, so that the workpiece 3 to be machined is ground. In the process of grinding the workpiece 3 to be processed, a large amount of scraps (mostly magnetic scraps such as iron filings) are generated, the first protective net 61 and the second protective net 62 have a good blocking effect on the scraps generated by processing, so that the scraps are concentrated in the cylindrical processing space formed by the first protective net 61 and the second protective net 62, and in addition, when the second fixing block 72 is attached to the first fixing block 71, as can be seen from the foregoing analysis, the storage battery 81, the negative metal sheet 84, the positive metal sheet 82, the electromagnet 85 and the wire 86 are connected in series to form a closed loop, so that the electromagnet 85 generates magnetism, and can concentrate and adsorb the magnetic scraps in the cylindrical processing space, thereby reducing the difficulty of cleaning the scraps by the staff. After the workpiece is ground, the worker only needs to take down the elastic positioning element 74 to separate the first protective net 61 from the second protective net 62, and at this time, the closed loop formed by the storage battery 81, the negative metal sheet 84, the positive metal sheet 82, the electromagnet 85 and the wire 86 disappears, so that the electromagnet 85 loses magnetism, and the debris in the cylindrical processing space falls onto the filter plate 92. When clearing up the piece on the filter 92, the staff only need open third motor 103, third motor 103 drives the threaded rod 104 rather than the output shaft is fixed after the work and takes place to rotate, so that first slider 105 and second slider 106 all move to the one side that is close to third motor 103, at this moment, first slider 105 drives the case 93 motion rather than fixed, magnet 94 in the case 93 sees through the case 93 and adsorbs the piece on the filter 92, meanwhile, the cleaning brush 932 of case 93 bottom has played good cleaning action to the non-magnetic material on the filter 92 upper surface, non-magnetic debris are along with cleaning brush 932 removes to piece collection frame 1112 one side. When the storage box 93 moves above the debris collection frame 1112, the worker only needs to open the cover 931 and take out the magnetic block 94, so that the debris outside the storage box 93 falls into the debris collection frame 1112. Meanwhile, the second sliding block 106 drives the sealing plug 96 to move towards one side close to the third motor 103 through the U-shaped connecting rod 107, so that the pressure between the sealing plug 96 and the side wall of the side, close to the collection box 91, of the recovery box 95 is reduced, and the cooling liquid in the collection box 91 enters the recovery box 95 through the connecting pipe 97, in the process, the filter screen 98 plays a good role in filtering, the content of impurities in the cooling liquid is reduced, and the cooling liquid is recycled again.

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