[0017] Beneficial effects of the utility model:

[0018] 1. By setting a baffle, the baffle can limit the bearing ring at the groove to prevent it from moving out of the placement groove, and then turn on the electric push rod to push the push block forward. The push block immediately applies a thrust to the placement plate to the bearing ring placed inside the placement groove. Since one side of the baffle is set with an inclined surface, when the bearing ring is subjected to the thrust movement, the baffle will be controlled by the inclined surface of the baffle to squeeze the second spring and hide itself inside the placement groove, making it easier for the bearing ring to move out of the placement groove. When a group of bearing rings is pushed out, the first spring immediately pushes the remaining bearing rings forward, causing the next group of bearing rings to conflict with the placement groove in preparation for pushing.

[0019] 2. By setting a nozzle, when the bearing ring is pushed onto the placement plate, the transmission motor set at one end of the grinding roller and the adjusting roller controls the grinding roller and the adjusting roller to rotate synchronously in the same direction. By cooperating with the adjusting roller, the surface of the bearing ring is polished. Because a rubber ring is set on the grinding roller, the bearing can be slowly transported to the side when the grinding roller rotates to realize the unloading operation. When grinding the bearing ring, the water pipe can be connected to the conduit so that water is sprayed out from the nozzle and contacts the bearing ring to achieve the purpose of dust reduction.

[0028] The top of the base 1 is fixedly connected to a frame 14, the top of the frame 14 is fixedly connected to a nozzle 15, the top of the nozzle 15 is fixedly connected to a conduit 16, a drain outlet 17 is provided inside the base 1 below the conduit 16, and a servo motor 18 fixedly connected to the base 1 is provided on one side of the drain outlet 17, and the output end of the servo motor 18 is fixedly connected to a forward and reverse screw rod 19 rotatably connected to the base 1, and the surface of the forward and reverse screw rod 19 is threadedly connected to two groups of sliders 20 slidingly connected to the base 1, the top of one group of sliders 20 is rotatably connected to a grinding roller 21, and the top of the other group of sliders 20 is rotatably connected to an adjusting roller 22, and a placement plate 23 fixedly connected to the base 1 is provided in the gap between the adjusting roller 22 and the grinding roller 21.

[0029] In this embodiment, the push plate 4 slides horizontally along the inside of the placement groove 2 under the action of the first spring 3. A "U"-shaped groove is provided on one side of the placement groove 2. When a group of bearing rings is pushed out, the first spring 3 immediately pushes the remaining bearing rings forward, so that the next group of bearing rings contacts the placement groove 2, preparing for pushing.

[0030] In this embodiment, a connecting hole larger than the push block 7 is provided inside the placement groove 2, and the push block 7 coincides with the center line of the "U"-shaped groove. The electric push rod 6 is turned on to push the push block 7 forward, and the push block 7 then applies a thrust to the placement plate 23 to the bearing ring placed inside the placement groove 2.

[0031] In this embodiment, the adjustment plate 11 and the side surface of the placement groove 2 are arranged parallel to each other. By setting the adjustment plate 11, the position of the adjustment plate 11 can be adjusted by screwing the adjustment screw 10 to achieve the function of limiting bearing rings of different sizes.

[0032] In this embodiment, the side of the baffle 13 close to the push block 7 is inclined, and the lowest point of the inclined surface of the baffle 13 is flush with the placement groove 2. When the bearing ring is subjected to thrust movement, the baffle 13 will be controlled by the inclined surface of the baffle 13 to squeeze the second spring 12 and hide itself inside the placement groove 2, so as to facilitate the bearing ring to move out of the placement groove 2.

[0033] In this embodiment, the grinding roller 21 and the adjusting roller 22 are arranged parallel to each other, and the grinding roller 21 and the adjusting roller 22 slide in opposite directions through the forward and reverse screw rods 19. The servo motor 18 is turned on to control the rotation of the forward and reverse screw rods 19, thereby controlling the relative movement of the two groups of sliders 20, thereby achieving the purpose of adjusting the distance between the grinding roller 21 and the adjusting roller 22.

[0034] In this embodiment, the surface of the adjustment roller 22 is tightly wrapped with a non-slip rubber layer. Since a rubber ring is provided on the grinding roller 21, when the grinding roller 21 rotates, the bearing can be slowly transported to the side to realize the unloading operation.

[0035] In this embodiment, the placement plate 23 is arranged at a central position in the gap between the grinding roller 21 and the adjusting roller 22. One end of the grinding roller 21 and the adjusting roller 22 is provided with a transmission motor whose output end is fixedly connected to itself and fixedly connected to the placement groove 2. When the bearing ring is pushed onto the placement plate 23, the transmission motor provided at one end of the grinding roller 21 and the adjusting roller 22 controls the grinding roller 21 and the adjusting roller 22 to rotate synchronously in the same direction. By cooperating with the adjusting roller 22, the operation of grinding the surface of the bearing ring is realized.

[0036] In this embodiment, the water outlet of the drain port 17 is vertically downward toward the placement plate 23, and the drain port 17 is arranged in a straight line and equidistantly. When grinding the bearing ring, the water pipe for conveying water can be connected to the conduit 16, so that water is sprayed out from the nozzle 15 and contacts the bearing ring to achieve the purpose of dust reduction. The drain port 17 can facilitate the discharge of water from the base 1.

[0037] After one group of bearing rings is pushed out, the first spring 3 immediately pushes the remaining bearing rings forward, causing the next group of bearing rings to conflict with the placement groove 2 and prepare for pushing.

[0038] When the bearing ring is pushed onto the placement plate 23, the transmission motors arranged at one end of the grinding roller 21 and the adjusting roller 22 control the grinding roller 21 and the adjusting roller 22 to rotate synchronously in the same direction. By cooperating with the adjusting roller 22, the operation of grinding the surface of the bearing ring is realized. Because a rubber ring is provided on the grinding roller 21, the bearing can be slowly transported to the side when the grinding roller 21 rotates to realize the unloading operation. When grinding the bearing ring, the water pipe for conveying water can be connected to the conduit 16 so that water is sprayed from the nozzle 15 and contacts the bearing ring to achieve the purpose of dust reduction. The drain outlet 17 can facilitate the discharge of water from the base 1. When the gap between the grinding roller 21 and the adjusting roller 22 needs to be adjusted, the servo motor 18 can be turned on to control the rotation of the forward and reverse screw rods 19, so as to control the relative movement of the two sets of sliders 20, so as to achieve the purpose of adjusting the distance between the grinding roller 21 and the adjusting roller 22.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
