[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 grinding and unloading device includes a main bearing 5 and a feeding frame 1 with a circular groove 11. An adjusting disc 2 is rotatably mounted within the circular groove 11. The side of the adjusting disc 2 has a U-shaped groove 22 adapted to the main bearing 5. A discharge groove 15 matching the U-shaped groove 22 is formed on the inner wall of the circular groove 11 along the rotation path of the U-shaped groove 22. A grinding disc 6 for grinding the end face of the main bearing 5 is rotatably mounted within the circular groove 11. Multiple main bearings 5 ​​are sequentially placed into the U-shaped groove 22 on the adjusting disc 2. With the rotation of the adjusting disc 2 and the grinding disc 6, the main bearings 5 ​​are fed and their end faces are ground. The rotating adjusting disc 2 aligns the ground main bearings 5 ​​with the discharge groove 15 for rapid discharge, thus solving the problems of manual handling of the main bearings 5 ​​and the high cost and complexity of electrically controlled discharge.

[0025] As a further technical solution provided by this utility model, it includes a mounting plate frame 4 and a mounting cover 41 disposed thereon. A drive motor 42 is fixedly installed inside the mounting cover 41, and a drive shaft 23 is fixedly installed at the output end of the drive motor 42. The drive shaft 23 is fixedly installed on the grinding disc 6.

[0026] Specifically, the grinding disc 6 is rotated by the drive motor 42 to grind the top surface of the main bearing 5.

[0027] Furthermore, a feed plate 14 matching the U-shaped groove 22 is fixedly installed on the feed rack 1.

[0028] Specifically, by having multiple main bearings 5 ​​sequentially enter the U-shaped groove 22 along the feed plate 14, it is easier to continuously feed and grind multiple main bearings 5, thereby improving production efficiency.

[0029] Furthermore, the top of the positioning disc 2 is provided with a storage groove 21, and a sun gear 32 and a planetary gear 33 are rotatably arranged in the storage groove 21. A cylindrical gear 3 is fixedly installed on the inner wall of the storage groove 21, and the planetary gear 33 meshes with the cylindrical gear 3 and the sun gear 32 respectively. The sun gear 32 is fixedly installed on the drive shaft 23.

[0030] Specifically, by using the drive motor 42 to drive the grinding disc 6 to rotate, the drive motor 42, in conjunction with the drive shaft 23, drives the sun gear 32 to rotate. Then, the sun gear 32 meshes with the planetary gear 33, and the planetary gear 33 meshes with the cylindrical gear 3 to drive the adjusting disc 2 to rotate. The adjusting disc 2 and the grinding disc 6 rotate in opposite directions. Thus, the drive motor 42 drives the grinding disc 6 and the adjusting disc 2 to rotate synchronously in opposite directions, thereby achieving the effect of feeding and grinding the main bearing 5.

[0031] Furthermore, an arc-shaped platform 13 is provided inside the circular groove 11, and inclined surfaces 17 are provided at both ends of the arc-shaped platform 13. The main bearing 5 is movably mounted on the inclined surfaces 17 and the arc-shaped platform 13.

[0032] Specifically, when the main bearing 5 enters the U-shaped groove 22 along the feed plate 14, the top of the main bearing 5 and the grinding disc 6 maintain a certain distance. Then, as the adjusting disc 2 rotates, the main bearing 5 in the U-shaped groove 22 gradually slides onto the inclined surface 17 and slides along the inclined surface 17 onto the top of the arc-shaped platform 13. At this time, the top of the main bearing 5 is attached to the grinding disc 6 and is ground by the grinding disc 6. After the grinding is completed, as the adjusting disc 2 rotates, the main bearing 5 slides off from another inclined surface 17 and rotates with the adjusting disc 2 to make the main bearing 5 correspond to the discharge groove 15 and quickly discharge the material.

[0033] Furthermore, an air cavity 12 is provided on the inner wall of the circular groove 11, and an air duct 7 is provided between the retaining ring 31 fixedly installed on the top of the cylindrical gear 3 and the air cavity 12.

[0034] Specifically, by utilizing the air cavity 12 and the air duct 7 provided between the baffle ring 31 and the air cavity 12, the metal shavings generated by the main bearing 5 are sucked up to reduce the accumulation of metal shavings. The suction of the air cavity 12 can be achieved by using a corresponding exhaust fan and exhaust equipment in conjunction with a filter screen.

[0035] Furthermore, a sanding pad 61 is fixedly installed on the bottom of the sanding disc 6.

[0036] Specifically, the main bearing 5 is polished by grinding the sanding pad 61.

[0037] Furthermore, the opening of the material discharge chute 15 is provided with a chamfered surface 16.

[0038] Specifically, the chamfered surface 16 can guide the falling main bearing 5 so that the main bearing 5 falls accurately into the discharge chute 15.

[0039] Furthermore, the grinding disc 6 is made of stainless steel.

[0040] Working principle: When the main bearing 5 enters the U-shaped groove 22 along the feed plate 14, the top of the main bearing 5 and the grinding disc 6 maintain a certain distance. Then, the drive motor 42 drives the grinding disc 6 to rotate. At the same time, the drive motor 42 cooperates with the drive shaft 23 to drive the sun gear 32 to rotate. Then, the sun gear 32 meshes with the planet gear 33, and the planet gear 33 meshes with the cylindrical gear 3 to drive the adjusting disk 2 to rotate. The adjusting disk 2 and the grinding disc 6 rotate in opposite directions.

[0041] Furthermore, as the adjusting disc 2 rotates, the main bearing 5 in the U-shaped groove 22 gradually slides onto the inclined surface 17 and slides along the inclined surface 17 to the top of the arc-shaped platform 13. At this time, the top of the main bearing 5 is attached to the grinding disc 6 and is ground by the grinding disc 6. After the grinding is completed, as the adjusting disc 2 rotates, the main bearing 5 slides off from another inclined surface 17 and rotates with the adjusting disc 2 to make the main bearing 5 correspond to the material drop groove 15 and quickly drop the material.

[0042] 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.
