[0002] A multi-aperture bearing ring is a bearing component with a special design and high adaptability. Its multi-aperture function enables it to adapt to a variety of different installation requirements and maintain excellent performance under various working conditions. During the production process of the bearing ring, the outer ring and the inner ring of the bearing need to be polished and ground to remove burrs on the outer ring and the inner ring of the bearing. At present, when the grinding mechanism is in use, most of them can only grind the outer ring or the inner ring of the bearing separately, and it is impossible to grind the outer ring and the inner ring of the bearing on the same grinding mechanism.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By pulling the pull block outward, the insertion rod is driven to break away from the interference with the insertion hole on the side wall of the grinding box. At this time, the rotating block can be easily rotated, and then the rotating block is rotated to drive the second screw to rotate, and further drive the second threaded block outside the second screw to move, so that the bottom limit block of the second threaded block and the second motor move.

The rotating hollow cylindrical magnet can be used to adsorb the iron filings entering the separation box, and the scraper can be used to collect the magnets adsorbed on the surface of the hollow cylindrical magnet into the iron filing collection frame, which is convenient for later use, saves resources and reduces costs. The dust entering the separation box will fall into the dust collection frame. In order to facilitate better dust collection, water resources can be added to the dust collection frame.

[0019] 3. The worm is driven to rotate by rotating the driving rod, and the worm and the worm wheel are used to drive the rotating rod and the driving wheel to rotate. The driving wheel and the driven wheel are used to drive the first screw to rotate. At the same time, the first threaded block outside the first screw will also rotate, thereby driving the extrusion roller to move to limit the multi-aperture bearings of different sizes to prevent the multi-aperture bearings from shifting in position during the grinding process. After that, the first motor is used in conjunction with the rubber roller and the turntable to drive the multi-aperture bearing to rotate smoothly, which is convenient for grinding the multi-aperture bearings.

DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] like Figures 1 to 8 As shown, the present invention provides:

[0031] A multi-aperture bearing ring all-round uniform grinding device comprises a grinding table 1, a support plate 2 is arranged on the top of the grinding table 1, a hydraulic rod 20 is arranged on the bottom of the support plate 2, a grinding box 6 is arranged on the movable end of the hydraulic rod 20, a second screw 24 is rotatably arranged inside the grinding box 6, the other end of the second screw 24 extends to the outside of the grinding box 6 and is provided with a rotating block 28, the second screw 24 is externally threadedly connected with a second threaded block 25, a limit block 26 is arranged at the bottom of the second threaded block 25, a slide groove for the limit block 26 to move is opened at the bottom of the grinding box 6, a second motor 22 is arranged at the bottom of the limit block 26, and a grinding rod 23 is arranged on the output shaft of the second motor 22.

[0032] The second screw 24 is driven to rotate by rotating the rotating block 28, and the second threaded block 25 outside the second screw 24 is further driven to move, so that the bottom limit block 26 of the second threaded block 25 and the second motor 22 are moved. The second motor 22 can drive the grinding rod 23 to work and fully grind the outer ring and the inner ring of the multi-aperture bearing respectively, avoiding the use of multiple devices to fully grind the outer ring and the inner ring of the multi-aperture bearing.

[0033] like Figure 6 As shown, the inside of the rotating block 28 is symmetrically provided with through holes for installing the plug rods 27, and a pull block 30 is provided at one end of the two plug rods 27. A spring 29 is sleeved on the outside of the plug rods 27, and one end of the spring 29 is connected to the side wall of the rotating block 28, and the other end of the spring 29 is connected to the side wall of the pull block 30. The side wall of the grinding box 6 is provided with a plurality of through holes adapted to the plug rods 27.

[0034] By pulling the pull block 30 outward, the insertion rod 27 is driven to break away from the interference with the insertion hole of the side wall of the grinding box 6, and the rotating block 28 can be easily rotated. When the second threaded block 25 is adjusted to a suitable position, the pull block 30 can be loosened, and the pull block 30 will drive the insertion rod 27 to move under the action of the spring 29, so that the insertion rod 27 is reinserted into the insertion hole of the side wall of the grinding box 6, preventing the second screw rod 24 from rotating during the grinding process.

[0035] like Figure 5 and Figure 7 As shown, a dust pump 4, a mounting cylinder 33 and a separation box 3 are respectively arranged on the top of the support plate 2. The input end of the dust pump 4 is connected to an air suction pipe 5. The other end of the air suction pipe 5 is connected to two suction nozzles 21. The two suction nozzles 21 are respectively arranged on both sides of the second motor 22.

[0036] Through the close cooperation between the suction pipe 5 and the suction nozzle 21, the dust and iron chips generated during the grinding process are effectively collected and safely transported to the separation box 3.

[0040] The dust and iron filings adhering to the surface of the rotating blade 34 can be cleaned by the cleaning brush 35. The cleaning brush 35 effectively removes the dust and iron filings accumulated on the rotating blade 34, ensuring the smooth operation of the equipment and extending the service life.

[0041] like Figure 8 As shown, a scraper 39 is disposed inside the separation box 3 to abut against the surface of the hollow cylindrical magnet, and a dust collecting frame 37 for collecting dust and an iron filings collecting frame 38 for collecting iron filings are movably disposed inside the separation box 3.

[0042] The rotating hollow cylindrical magnet 36 can adsorb the iron filings entering the separation box 3, and then the scraper 39 can be used to collect the magnets adsorbed on the surface of the hollow cylindrical magnet 36 into the iron filing collection frame 38, which is convenient for later use, saves resources and reduces costs. The dust entering the separation box 3 will fall into the dust collection frame 37. In order to facilitate better dust collection, water resources can be added to the dust collection frame 37.

[0044] By rotating the first screw 12, the first threaded block 13 outside the first screw 12 will also rotate, thereby driving the extrusion roller 7 to move to limit the multi-aperture bearings of different sizes, thereby preventing the multi-aperture bearings from shifting in position during the grinding process.

[0045] like Figure 2 As shown, a first motor 10 is disposed on the top of one of the squeezing rollers 7, and a rubber roller 11 for driving the multi-aperture bearing to rotate is disposed on the output shaft of the first motor 10.

[0046] The first motor 10 cooperates with the rubber roller 11 and the turntable 9 to drive the multi-aperture bearing to rotate smoothly, making it convenient to grind the multi-aperture bearing.

[0047] like Figure 4 As shown, an adjusting frame 8 is provided at the bottom of the grinding table 1, a driving rod 17 is rotatably provided inside the adjusting frame 8, a worm 18 is provided at one end of the driving rod 17, a worm wheel 19 meshingly connected with the worm 18 is provided inside the adjusting frame 8, a rotating rod 15 is provided on the top of the worm wheel 19, the top of the rotating rod 15 extends to the outside of the grinding table 1, and a driving wheel 16 meshingly connected with the driven wheel 14 is provided on the outside of the rotating rod 15.

[0048] The worm 18 is driven to rotate by rotating the driving rod 17 , and the worm 18 cooperates with the worm wheel 19 to drive the rotating rod 15 and the driving wheel 16 to rotate, and the driving wheel 16 cooperates with the driven wheel 14 to rotate to drive the first screw 12 to rotate.

[0049] like Figure 3 As shown, a multi-aperture bearing turntable 9 is provided on the top of the rotating rod 31 .

[0050] The rotating disk 9 facilitates the placement of multi-aperture bearing rings.

[0051] The above embodiments only express a multi-aperture bearing ring all-round uniform grinding device or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
