[0026] As Figures 1 to 6 shown, the present utility model provides:

[0027] A circumferential wall grinding device for machining shaft workpieces, including a bottom frame 1, a grinding frame 2 is arranged on the top of the bottom frame 1, a dust suction pump 4 is arranged on the top of the grinding frame 2, an isolation box 3 is arranged on the side wall of the grinding frame 2, symmetric electromagnetic slide rails 10 are arranged inside the grinding frame 2, an electromagnetic slider 9 is slidably arranged outside the electromagnetic slide rails 10, a movable plate 5 is arranged on the top of the electromagnetic slider 9, an electric push rod 11 is arranged on the bottom of the movable plate 5, a protective cover 13 is arranged at the telescopic end of the electric push rod 11, a second motor 14 is arranged inside the protective cover 13, a grinding rod 15 is arranged on the output shaft of the second motor 14, the input end of the dust suction pump 4 is communicated with the inside of the protective cover 13 through a pipeline, and the output end of the dust suction pump 4 is communicated with the inside of the isolation box 3 through a pipeline.

[0028] It is adsorbed into the inside of the isolation box 3 through the cooperation of the dust suction pump 4 and the pipeline, preventing these crushed and metal chips from floating around in the air and polluting the environment, and also protecting the physical and mental health of the staff.

[0029] As Figure 2 shown, symmetric support blocks 6 are arranged on the top of the bottom frame 1, an electric chuck 8 is arranged on the opposite side of the two support blocks 6, and a first motor 7 is arranged on the side wall of one of the support blocks 6, and the output shaft of the first motor 7 is connected to the side wall of the electric chuck 8.

[0030] By using the two electric chucks 8, the shaft workpiece can be placed between the two electric chucks 8, and the first motor 7 can be used to drive the shaft workpiece to rotate, which is convenient for cooperating with the grinding rod 15 to work.

[0031] As Figure 6As shown, a partition plate 26 is provided inside the isolation box 3 , a cylindrical electromagnet 23 is rotatably provided inside the isolation box 3 , and a scraper 25 is provided on the top of the partition plate 26 to abut against the cylindrical electromagnet 23 .

[0032] The cylindrical electromagnet 23 can absorb metal debris to its surface, and the scraper 25 can scrape the metal debris on the surface of the cylindrical electromagnet 23 into the inside of the collecting bin 27, so as to facilitate the secondary use of the metal debris in the later stage.

[0033] like Figure 6 As shown, a water frame 24 for collecting dust and a collecting drawer 27 for collecting iron filings are movably provided inside the isolation box 3 .

[0034] The falling dust can be collected by the water frame 24 .

[0035] like Figure 3 and Figure 4 As shown, symmetrical connecting rods 12 are provided at the bottom of the movable plate 5, and a cleaning brush 16 is provided between the two connecting rods 12 to contact the surface of the bottom frame 1. The surface of the bottom frame 1 is provided with a plurality of through holes for dropping dust and debris.

[0036] The dust and metal debris dropped on the top of the bottom frame 1 can be cleaned into the inside of the bottom frame 1 by the cleaning brush 16 .

[0037] like Figure 5 As shown, a symmetrical support plate 19 is movably provided inside the bottom frame 1, a symmetrical spring telescopic rod 22 is provided at the bottom of the support plate 19, the other end of the spring telescopic rod 22 is connected to the bottom frame 1, and an inclined magnetic block 20 is provided on the side wall of the support plate 19.

[0042] The chip collecting drawer 21 can be used to collect the dust that has fallen inside the bottom frame 1.

[0043] Working principle: First, place the shaft workpiece to be polished between the two electric chucks 8. Then, start the jaws on the electric chuck 8 to clamp the shaft workpiece. Next, use the first motor 7 to drive the shaft workpiece to rotate, which is convenient for cooperating with the polishing rod 15 to work. Then, control the electromagnetic slider 9 to drive the movable plate 5 to move. While the movable plate 5 is moving, it will also drive the electric push rod 11 and the connecting rod 12 to move. Use the telescopic end of the electric push rod 11 to adjust the second motor 14 to a suitable position. Then, the second motor 14 drives the polishing rod 15 to polish the outer wall of the shaft workpiece. During the polishing process, a large amount of dust and metal chips will be generated. Part of these dust and metal chips will be adsorbed into the isolation box 3 by the dust suction pump 4 working with the pipeline, preventing these crushed and metal chips from floating around in the air and polluting the environment, and also protecting the physical and mental health of the staff. For the dust and metal chips sucked into the isolation box 3, the metal chips will be adsorbed onto the surface of the cylindrical electromagnet 23 under the action of the cylindrical electromagnet 23, and then the metal chips on the surface of the cylindrical electromagnet 23 can be scraped into the collection drawer 27 by the scraping block 25, which is convenient for the secondary utilization of the metal chips later. The dust will fall into the water frame 24. The dust and metal chips that have fallen on the top of the bottom frame 1 will be cleaned by the cleaning brush 16 into the inside of the bottom frame 1. The metal chips and crushed materials that have fallen into the bottom frame 1 will fall on the surface of the inclined iron absorber 20. The metal dust will stay on the surface of the iron absorber 20 under the action of magnetic force, and the dust will fall into the inside of the chip collecting drawer 21 under the action of the inclined plane. In order to prevent the dust from being squeezed on the surface of the magnet, when the connecting rod 12 moves, it will squeeze the contact ball 18. After being squeezed, the contact ball 18 will drive the support plate 19 to move downward, thereby squeezing the spring telescopic rod 22, making the support plate 19 in a vibrating state, which can effectively shake off the dust squeezed on the surface of the iron absorber 20.
