Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, a bearing roller end face grinding machine includes a grinding machine 1, including a rough grinding roller 41 and a fine grinding roller 51 arranged on the grinding machine 1 and sequentially arranged along the feed direction;

[0025] A fluid collection tank 8 is provided on the grinding machine 1, which is used to recover the grinding fluid;

[0026] The suction port 9 is provided on the liquid collection tank 8;

[0027] The cover 7 installed in the collection tank 8 moves vertically to intermittently close the suction port 9, and a sealed water column is formed in the suction port 9 in the closed state, which is higher than the bottom side of the collection tank 8.

[0028] Specifically, it also includes a loading roller 2 for transporting multiple bearing rollers and a dust cover 3 mounted on the grinding machine 1, with both the coarse grinding roller 41 and the fine grinding roller 51 housed within the dust cover 3. The coarse grinding roller 41 is equipped with a transmission gear 4, and the fine grinding roller 51 is equipped with a driven gear 5 that meshes with the transmission gear 4. The coarse grinding roller 41 is driven to rotate by a drive motor, which in turn drives the fine grinding roller 51 to rotate. Because the coarse grinding roller 41 and the fine grinding roller 51 are driven by gear meshing, their rotation directions are opposite, resulting in opposite grinding directions on the bearing rollers, allowing for more precise grinding of the end faces.

[0029] Furthermore, it also includes a nozzle for spraying grinding fluid. The roller is driven by the feeding wheel 7 to pass through the coarse grinding roller 41 and the fine grinding roller 51 in sequence, simultaneously completing the transition from coarse to fine grinding. During the grinding process, the grinding fluid enhances the grinding effect and reduces the heat generated during friction. Subsequently, the grinding fluid flows into the collection tank 8 and is drawn in by the suction port 9. The port of the suction port 9 is higher than the bottom of the collection tank 8, driving the cover 7 to move up and down vertically. As the grinding fluid enters the suction port 9, a water column is formed inside the suction port 9. At this time, the cover 7 is driven to block the suction port 9, and the water column inside the suction port 9 is maintained under atmospheric pressure. When the cover 7 is opened again, the suction port 9 produces a siphon effect on the grinding fluid in the collection tank 8, making the suction effect better. Moreover, the water flow during the suction process is intermittent, which has a better impact force than the conventional uniform flow, and can disperse blockages caused by debris or rust in the pipeline.

[0030] The driving source used to drive the cap 7 can be a telescopic cylinder, an electric telescopic rod, or other driving methods known to those skilled in the art.

[0031] In the above technology, the roller is driven by the feeding wheel 7 to pass through the coarse grinding roller 41 and the fine grinding roller 51 in sequence, and simultaneously completes the transition from coarse grinding to fine grinding. Furthermore, the grinding fluid in the collection tank 8 is siphoned through the suction port 9, resulting in better suction effect. The water flow during the suction process is intermittent, which has a better impact force compared to the conventional uniform flow, and can disperse the blockage caused by debris or rust in the pipeline.

[0032] As a further embodiment of this utility model, a side filter 75 is provided on the cover 7, and a plurality of rotating blades 76 are arranged in a circumferential array on the side filter 75.

[0033] Specifically, during the process of the grinding fluid being drawn in, the excessive flow rate will generate a vortex around the suction port 9. This vortex can drive the rotating blade 76 to rotate, thereby dispersing the agglomerated debris and other impurities through the rotating blade 76, and intercepting the debris through the filter screen 75.

[0034] However, since the cover 7 will move up and down in the vertical direction, it will inevitably cause a gap between the filter screen 75 and the suction port 9. The debris under this gap will not be filtered and will flow directly into the suction port 9.

[0035] As a further embodiment of the present invention for solving the above-mentioned problems, it also includes an upper filter screen 73 disposed between the cover 7 and the liquid collection tank 8, and a rotating blade 76 is rotatably disposed relative to the upper filter screen 73.

[0036] Specifically, the upper filter screen 73 is made of an elastic and stretchable material. When the cover 7 moves up and down, the upper filter screen 73 filters the grinding fluid in the collection tank 8, causing the debris to remain above the upper filter screen 73. When the cover 7 moves down and fits tightly against the suction port 9, the upper filter screen 73 is pulled into a bucket shape, causing the debris from the filter screen to roll down along the upper filter screen 73 into the side filter screen 75, and finally be collected in the side filter screen 75, making subsequent recycling more convenient.

[0037] As another embodiment provided in this utility model, a plurality of limiting rails 81 are inclinedly arranged on the side wall of the liquid collection tank 8, and a plurality of protrusions 74 are provided on the rotating blade 76 to slide and cooperate with the limiting rails 81.

[0038] Specifically, the limiting rail 81 has a high position and a low position, and an anti-detachment baffle is provided at the low position. The side filter 75 and the cover 7 are fixedly connected, and the side filter 75 is rotatably disposed inside the upper filter 73. When the rotating blade 76 rotates under the drive of the eddy current, it drives the protrusion 74 to slide along the limiting rail 81, and the sliding direction is along the limiting rail 81 from the low position to the high position, thereby driving the side filter 75 and the cover 7 to move upward and there is a gap between them and the suction port 9, so that the grinding fluid in the liquid collection tank 8 is sucked out through the suction port 9. Then the rotating blade 76 continues to rotate downward, causing the protrusion 74 to disengage from the high position and fall to the low position under the action of gravity. At this time, the anti-detachment baffle limits the protrusion 74 to prevent the protrusion 74 from slipping.

[0039] As another embodiment further provided in this utility model, the cap 7 moves synchronously with the grinding roller 51.

[0040] Specifically, it also includes a rotating cylinder, which is connected to the grinding wheel 51 via a second transmission belt 72, and to the cover 7 via a first transmission belt 71. The rotation of the grinding wheel 51 drives the cylinder to rotate, and the cylinder then drives the cover 7 to rotate, providing rotational power for the cover 7, the side filter screen 75, and the rotating blade 76. This eliminates the need for eddy current propulsion, making the whole system more stable.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
