During operation, the protection plate 41 is pushed to one side of the fixing plate 42, when the protection plate 41 moves to one side of the fixing plate 42, the protection plate 41 extrudes the rubber plate 43 to enable the rubber plate 43 to shrink, the protection plate 41 is close to one side of the fixing plate 42, the working cavity 31 is opened at the moment, a workpiece is placed in the working cavity 31, the protection plate 41 is pulled during machining, the protection plate 41 is attached to one side of the working cavity 31, sealing of the working cavity 31 is achieved, and precision machining is facilitated.

In order to prevent the protection plate 41 from falling from the working cavity 31 when sliding, a first sliding strip 44 is arranged on the top of the protection plate 41 along the length direction of the protection plate, a first sliding groove 35 is formed in the top of the working cavity 31 along the length direction of the protection plate, the first sliding strip 44 is connected with the first sliding groove 35 in a sliding mode, when the protection plate 41 slides in the working cavity 31, the first sliding strip 44 on the top of the protection plate 41 is clamped in the first sliding groove 35 to slide in a positioning mode, so that the top of the protection plate 41 and the working cavity 31 are positioned and prevented from falling, a second sliding strip 45 is arranged on the bottom of the protection plate 41 along the length direction of the protection plate, a second sliding groove 36 is formed in the bottom of the working cavity 31 along the length direction, the second sliding strip 45 is connected with the second sliding groove 36 in a sliding mode, when the protection plate 41 slides in the working cavity 31, the second sliding strip 45 on the bottom of the protection plate, prevent it and drop, slide at the upper and lower both ends of working chamber 31 through the upper and lower both ends location of guard plate 41, realize that the holistic location of guard plate 41 slides, avoid guard plate 41 to drop.

During machining, a certain vibration force is generated due to the fact that the polishing disc 32 is polished, the vibration force is generated in the working cavity 31 and acts on the protection plate 41, the protection plate 41 is subjected to vibration force to deflect, and the working cavity 31 cannot be completely sealed, therefore, the end, far away from the rubber plate 43, of the protection plate 41 is provided with the clamping strip 46, one end, close to the operation box 2, of the working cavity 31 is provided with the clamping groove 37, the clamping strip 46 is in clamping fit with the clamping groove 37, the clamping strip 46 is preferably made of rubber materials, the materials of the clamping strip 46 have good elasticity, when the protection plate 41 is closed, the clamping strip 46 of the protection plate 41 is clamped into the clamping groove 37, on one hand, sealing of the protection plate 41 and the clamping groove 37 is achieved, on the other hand, the vibration force can be weakened through the elasticity of the clamping.

Because the surface of the protection plate 41 is flat, the friction resistance of the surface of the protection plate 41 is small, the protection plate 41 is difficult to drive to move by directly pushing and pulling the protection plate 41 by hands, and the handle 47 is arranged on the outer wall of the protection plate 41, so that an operator can conveniently hold the protection plate 41 by the handle 47, and the protection plate 41 is convenient to push and pull.

Although the protective cover 4 is arranged to block all flying dust in the working chamber 31, the accumulation of flying dust in the working chamber 31 still affects the processing precision, therefore, the positioning plate 5 is arranged in the working chamber 31, the positioning plate 5 comprises two symmetrically arranged placing plates 51, the placing plates 51 are trapezoidal, the two trapezoidal placing plates 51 are symmetrically placed, fixing grooves for fixing workpieces are naturally formed in the two placing plates 51, meanwhile, the inclined edges on the two sides facilitate the flying dust to slide down along the inclined edges of the placing plates 51, so that the same collection of the flying dust is facilitated, the fixing plate 42 is arranged between the two placing plates 51, the fixing plate 42 is connected between the inclined edges of the two placing plates 51, so that the flying dust can slide into the fixing plate 42 along the placing plates 51 on the two sides, the fixing plate 42 is internally provided with the leakage holes 53, so that the flying dust on the surface of the fixing plate 42 can enter the leakage holes 53 to.

The machine tool of the invention collects the following fly ash: during processing, the flying dust scattered on the positioning plate 5 in the working cavity 31 slides into the fixing plate 42 along the inclined edge of the positioning plate 5 and enters the leakage hole 53 for uniform collection.

Because the positioning plate 5 is positioned inside the processing cavity 31, the fly ash collected inside the fixed plate 42 is inconvenient to clean, the discharge box 33 is installed at the bottom of the processing box 3, the bottom of the discharge box 33 is communicated with the leakage hole 53, the fly ash collected in the leakage hole 53 inside the fixed plate 42 directly falls into the discharge box 33, meanwhile, the outer wall of the discharge box 33 is hinged with the box door 34, the box door 34 is hinged with the discharge box 33, and the box door 34 is convenient to open and clean the fly ash inside the discharge box 33.

In the actual working process, because the sizes of the scraps produced by processing are unequal, the larger scraps cannot be discharged from the leakage hole 53, and the guide pillar flying dust still can be accumulated in the working cavity 31 and is difficult to clean. Therefore, the inner wall of the leak hole 53 of the invention is provided with a pair of gear shafts 54, the gear shafts 54 are cylindrical structures, the surface is annularly arrayed with a plurality of teeth, the two gear shafts 54 rotate to cut larger waste, the waste with larger volume is prevented from being blocked at the leak hole 53, the gear shafts 54 are internally and coaxially provided with the main shaft 57, the main shaft 57 and the gear shafts 54 can synchronously rotate conveniently, one end of the inner wall of the leak hole 53 is provided with the rotating ring 55, one end of the main shaft 57 is rotatably connected in the rotating ring 55, the main shaft 57 rotates in the rotating ring 55 to realize that one end of the gear shafts 54 rotates in the inner wall of the leak hole 53, the other end of the main shaft 57 passes through the connecting plate 52 to be connected with the rotating motor 56, the main shaft 57 is synchronously rotated by the rotating motor 56 to realize the rotation of the gear shafts 54, the rotating directions of the two rotating motors 56 are opposite, so that the two gear shafts 54 rotate relatively, on the one hand, on the other hand, when the scraps with larger volume are stuck at the leaking hole 53, the scraps can be crushed by the relatively rotating gear shaft 54, and the crushed scraps are discharged into the leaking hole 5.

The during operation inserts the power respectively with two rotating electrical machines 56, makes its work, and two rotating electrical machines 56 drive two gear shafts 54 and rotate relatively, when the great sweeps card of volume was in small opening 53 department, can carry out the breakage to the sweeps through relative pivoted gear shaft 54 to in discharging the sweeps after the breakage into small opening 5, the fly ash on gear shaft 54 surface is also pushed into small opening 53 simultaneously, prevents that small opening 5 from blockking up.

In the actual operation process, because the position of the main shaft 57 is close to the bottom of the working chamber 31, it is difficult to mount the output shaft of the rotating electric machine 56 coaxially with the main shaft 57, therefore, the rotating electric machine 56 of the present invention is located at the top of the gear shaft 54, so that the rotating electric machine 56 has a certain mounting height, the output shaft of the rotating electric machine 56 is coaxially mounted with the connecting shaft 58, the connecting shaft 58 is the power output shaft of the rotating electric machine 56, the connecting shaft 58 and the main shaft 57 are in transmission connection through the transmission belt 59, and the working mode is as follows: the rotating motor 56 drives the connecting shaft 58 to rotate, the connecting shaft 58 drives the main shaft 57 to rotate through the transmission belt 59, and the main shaft 57 drives the gear shaft 54 to rotate.
