[0023] Please refer to the accompanying drawings Figure 1 - the accompanying drawings Figure 6 In one preferred implementation, the prompting assembly comprises: a rack 15 slidably arranged on the outside of the first slide 3, a horizontal groove 20 is formed on the side of the first slide 3, a protrusion is fixedly installed on the side of the first sliding block 31, the protrusion passes through the horizontal groove 20 and is fixedly installed on the side of the rack 15, a gear 16 is rotatably installed on the side of the first slide 3 and engaged with the rack 15, a plurality of first spring rods 17 are fixedly installed on the side of the gear 16, a ball 18 is fixedly installed on the telescopic end of each first spring rod 17, an iron plate 19 is fixedly installed on the top of the first slide 3, and the ball 18 can impact the iron plate 19; Preferably, the ball 18 and the iron plate 19 impact to emit a sound to prompt the worker to replace the millstone 9 in time.

[0024] Please refer to the accompanying drawings Figure 1 - the accompanying drawings Figure 3 In one preferred implementation, the fixing assembly comprises: two clamping plates 5 symmetrically slidably arranged on the top of the workbench 1, a chuck 7 is rotatably installed on the opposite side of each clamping plate 5, a first motor 8 is installed on the side of one of the clamping plates 5, the output shaft of the first motor 8 is installed at the center of the side of the corresponding chuck 7, an electric telescopic rod 6 is installed on the outside of each vertical edge of the U-shaped frame 2, and the output shaft of each electric telescopic rod 6 is installed on the side of each clamping plate 5, for fixing the cast iron part to be polished.

[0025] The working principle of the present application is as follows: first, place the cast iron part between the two chucks 7, move the two clamping plates 5 through the two electric telescopic rods 6, move the two chucks 7 through the movement of the two clamping plates 5, so as to clamp the cast iron part, then rotate the fixed cast iron part through the first motor 8, so as to ensure the comprehensiveness of the polishing of the cast iron part. Then the first slide 3 and its connecting components such as the grinding disc 9 are moved down by the hydraulic telescopic rod 4, and then the first rotating shaft 11 is rotated by the second motor 10, the grinding disc 9 is rotated by the rotation of the first rotating shaft 11, the second rotating shaft 12 is rotated by the rotation of the spline sleeve 27, and the grinding disc 9 is rotated by the rotation of the second rotating shaft 12, so that the cast iron workpiece can be fully polished; When the grinding disc 9 is damaged, deformed, and uneven (that is, the grinding disc 9 is deformed and is no longer circular, which is equivalent to a cam disc), the second motor 10 rotates to drive the grinding disc 9 to rotate, which causes the second rotating shaft 12, the first rotating shaft 11, and the second motor 10 to vibrate. Due to the arrangement of the first slide 3 and the first sliding block 31, the second motor 10 and the first sliding block 31 move horizontally and reciprocally, the first sliding block 31 moves horizontally and reciprocally and contacts the L-shaped stop plate 42 to drive the L-shaped stop plate 42 to move, the L-shaped stop plate 42 moves to drive the second sliding block 34 to move, the second sliding block 34 moves to drive the second movable rod 35 to move, the second movable rod 35 moves to drive the vertical column 22 to move up and down reciprocally, and the vertical column 22 moves up and down reciprocally to drive the piston plate 21 to move up and down reciprocally.

Due to the increase of the air pressure in the air sleeve 25, the cylindrical column 40 drives the sleeve ring 26 to move upward (the cylindrical column 40 does not separate from the cylindrical groove 39, and the air sleeve 25 is provided with a pressure relief valve for facilitating pressure relief by the worker), the sleeve ring 26 moves upward to drive the spline sleeve 27 and the first movable rod 29 to move downward, the spline sleeve 27 moves upward to separate from the second rotating shaft 12, so that the first rotating shaft 11 does not drive the grinding disc 9 to rotate, and the driving of the grinding disc 9 is released; The first movable rod 29 moves to drive the friction block 28 to move, the friction block 28 moves to contact the second rotating shaft 12, and the grinding disc 9 and the second rotating shaft 12 which continue to rotate due to inertia are stopped, so that the continuous splashing of the fragments on the grinding disc 9 and the continuous damage to the cast iron workpiece are reduced. In addition, the movement of the first sliding block 31 drives the rack 15 to move reciprocally through the protrusion, the rack 15 drives the gear 16 to rotate, the gear 16 drives the plurality of first spring rods 17 to revolve, and due to the centrifugal force, the ball 18 and the iron plate 19 collide to emit a sound, so as to prompt the worker that the grinding disc 9 is damaged and can be processed in time; In summary, the grinding disc 9 can be self-checked during work, and the grinding disc 9 can be quickly stopped after self-checking and prompt the worker, thereby improving the use effect of the equipment.
