The bottom of the lifting fixture table 3 is connected to an industrial vacuum cleaner 14 installed on the bottom side of the grinding table 1, which is used to collect the generated waste chips by the suction force of the industrial vacuum cleaner 14;

[0027] The lifting guard plate 5 is movable and runs through the four sides of the lifting fixture platform 3, so that the lifting guard plate 5 is lifted and lowered to form a protective cavity during the die cutting process, thereby achieving all-round protection during grinding and reducing the damage to the staff caused by the splashing of waste chips during grinding. The lifting guard plate 5 is located at one end of the grinding table 1 and is magnetically connected to a driving strip plate 6 with an L-shaped structure, so that the driving strip plate 6 moves along with the lifting of the lifting fixture platform 3 on the guide vertical rod 7. The driving strip plate 6 is provided with a guide vertical rod 7 for guiding the driving strip plate 6 to lift and lower, so that the driving strip plate 6 can achieve the effect of horizontal lifting during the lifting process, avoiding the problem of the lifting guard plate 5 being tilted and stuck in the strip groove 8.

[0028] The four sides of the square through hole 2 are all provided with strip grooves 8 at the outward positions, so that the lifting guard plate 5 can pass through the strip grooves 8 to form a square frame-shaped protective cavity for comprehensive protection, and the lifting guard plate 5 is movably arranged on the inner side of the strip groove 8, which is conducive to the lifting guard plate 5 to rise or fall to the upper end and the inside of the grinding table 1. The bottom of the lifting guard plate 5 is provided with a magnetic fixing block 9, which is conducive to the magnetic disassembly and assembly of the lifting guard plate 5 and convenient for taking and placing the workpiece, and the magnetic block is provided with a metal slot 10 magnetically combined with the magnetic fixing block 9 at the position of the upwardly extending end of the driving strip plate 6, so that the lifting guard plate 5 can be vertically magnetically plugged and combined with one end of the driving strip plate 6, which is conducive to the later disassembly and assembly, and the lifting guard plate 5 is a transparent acrylic guard plate, and the grinding of the workpiece can be observed. The guide vertical rod 7 is movably connected to the two ends of the driving strip 6, which is beneficial to the guiding and sliding up and down of the driving strip 6, and the bottom end of the guide vertical rod 7 is sleeved with an elastic member 11 connected to the bottom end of the inner part of the grinding table 1, so that the driving strip 6 can automatically rise by utilizing its elasticity in the absence of an upward thrust, and the two ends of the guide vertical rod 7 are vertically fixed inside the grinding table 1, and the interior of the grinding table 1 is symmetrically provided with an electric telescopic rod A12, which can enable the lifting fixture table 3 to be lifted and lowered, and the top of the electric telescopic rod A12 is fixedly connected to the bottom of the lifting fixture table 3, and the surface of the lifting fixture table 3 is penetrated by a square plate 13 with a suction hole, which is used to absorb and collect waste chips generated during the grinding process using the suction holes on the square plate 13.

[0029] The input end of the industrial vacuum cleaner 14 is connected to a suction hose 15, so that the suction hose 15 generates suction, so that the suction hole on the square plate 13 absorbs the waste. One end of the suction hose 15 is connected to a suction cover 16 installed at the bottom of the lifting fixture platform 3, and the absorbed waste is concentrated into the interior of the suction hose 15 for transportation. The four sides of the lifting fixture platform 3 are symmetrically provided with push rods 17, which can make the lifting fixture platform 3 descend, and use the push rods 17 to push the driving strip plate 6 downward to move the lifting guard plate 5 downward to the grinding Inside the table 1, one end of the push rod 17 is attached to the upper end surface of the driving strip plate 6, and a vertical pole frame 18 is set at the end of the grinding table 1. An electric telescopic rod B19 is symmetrically provided on the bottom side of the crossbeam of the vertical pole frame 18. A servo grinding motor 20 is fixed on a movable plate provided at the bottom end of the electric telescopic rod B19. The rotating shaft of the servo grinding motor 20 is fixed at the center position of the upper end surface of the grinding disk 4, so that the grinding disk 4 can be moved down to the bottom side of the formed protective cavity to grind the workpiece to avoid damage caused by waste chips splashing upward.

[0030] Specifically, when in use, the workpiece is first clamped on the lifting fixture table 3 in the square through hole 2 on the grinding table 1, and the workpiece is clamped by the fixture on the lifting fixture table 3. Then the electric telescopic rod A12 pushes the workpiece on the lifting fixture table 3 through the square through hole 2 to the upper end of the grinding table 1, and while the lifting fixture table 3 rises, the push rod 17 moves upward accordingly so that the compressed elastic member 11 elastically pushes the driving strip plate 6 to rise closely on the guide vertical rod 7. The rise of the driving strip plate 6 causes the vertically connected lifting guard plate 5 to pass through the strip groove 8 and follow the liquid to rise from the four directions of the square through hole 2. After the plate 5 rises to the maximum height, the electric telescopic rod A12 stops working, so that the lifting guard plates 5 in four directions form a protective cavity, and the lifting fixture table 3 is located at the bottom side of the protective cavity, which can achieve all-round protection. At this time, the electric telescopic rod B19 moves downward to push the grinding disc 4 installed on the rotating shaft of the servo grinding motor 20 to move down to the workpiece on the bottom side of the protective cavity. The pneumatic servo grinding motor 20 drives the grinding disc 4 to grind the workpiece. The waste chips generated during the grinding process are blocked by the square protective cavity shell to prevent the waste chips from flying around, thereby avoiding the problem of injuries to workers caused by waste chips flying around.

[0031] During the grinding process, the industrial vacuum cleaner 14 generates suction, so that the suction hose 15 and the suction hood 16 cooperate to make the suction holes on the surface of the square plate 13 generate suction, and the waste chips are adsorbed by the suction force to reduce the splash of waste chips and cause accidental injuries to the staff. At the same time, the workpiece that has been polished can be easily removed by pulling the lifting guard plate 5 on one side out of the metal slot 10 on the driving strip plate 6 by using the magnetic fixing block 9, and the completed workpiece can be removed from the lifting fixture table 3, and the new workpiece can be clamped and fixed on the lifting fixture table 3 and the lifting guard plate 5 can be removed into the metal slot 10 on the driving strip plate 6 by using the magnetic fixing block 9 for assembly and grinding again, so that the workpiece can be taken and placed more simply and conveniently.
