Description

Technical Field

[0001] This utility model relates to the field of marine fan technology, specifically to a surface grinding device for bearing processing. Background Technology

[0002] A bearing is a mechanical component used to support and reduce friction between rotating parts in a machine. They are typically used to support rotating components on a rotating shaft, allowing these components to reduce friction and transmit force during relative motion. Bearings generally consist of an inner ring, an outer ring, rolling elements (such as balls, rollers, and sliders), and a cage (which holds the rolling elements in their relative positions). During manufacturing, bearings undergo surface grinding to reduce surface roughness, making them smoother. This helps reduce friction and wear, improving bearing efficiency and lifespan.

[0003] Existing grinding equipment can only grind one side of a bearing. The other side can only be ground after the grinding equipment stops operating and the bearing is flipped over. This process results in low work efficiency, so improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a surface grinding device for bearing processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a surface grinding device for bearing processing, comprising a base plate for placing the bearing, a placement rod installed at the top of the base plate, a placement plate installed on the outer surface of the placement rod, a threaded groove opened on the side surface of the placement rod near the placement plate, and a nut movably screwed onto the outer surface of the threaded groove, and further comprising: two sets of grinding rods for grinding the inner and outer surfaces of the bearing;

[0006] One end of each of the two sets of grinding rods is installed on one side of the mounting plate, and a connecting rod is installed on the top of the mounting plate. A connecting plate is installed on the side surface of the connecting rod near the top, and one end of the connecting plate is installed on the side surface of the drive shaft. The top of the drive shaft is connected to the output end of the motor, and the motor is embedded in the top plate. A movable plate is installed at the bottom of the top plate, and a slider is installed at the bottom of the movable plate.

[0007] An electric push rod is used to drive the movable plate to move back and forth. One end of the electric push rod is installed with one side of the movable plate, and the other end of the electric push rod is installed with one side of the side plate.

[0008] Preferably, an extension plate is installed on the side surface of the base plate, and the top end of the extension plate is flush with the top end of the base plate.

[0009] The top of the extension plate is installed at one side of the side plate and is mounted at the bottom of the side plate.

[0010] Preferably, the top surface of the extension plate is provided with a groove, and one end of the groove extends to the top surface of the base plate;

[0011] The slider is located inside the groove and is slidably connected to it.

[0012] Preferably, the movable plate is positioned above the base plate and is located on one side of the placement rod.

[0013] Preferably, the drive shaft is positioned above the placement rod, and the drive shaft, connecting plate, and connecting rod together form a Z-shaped arrangement.

[0014] Preferably, the two sets of polishing rods are arranged in a parallel manner, one above the other.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By incorporating components such as extension plates, slides, side plates, electric push rods, moving plates, sliders, top plates, motors, drive shafts, connecting plates, connecting rods, mounting plates, and grinding rods, the existing grinding devices can effectively solve the problem of low work efficiency when grinding bearings. These devices can only grind one side of the bearing, while the other side can only be ground after the grinding device stops operating and the bearing is flipped over.

[0017] The user can place the bearing onto the outer surface of the placement rod and overlap it on the top surface of the placement plate. Then, the nut can be movably screwed onto the outer surface of the threaded groove and rotated downwards, ensuring the bottom surface of the nut tightly fits against the top surface of the bearing. This secures the bearing to the outer surface of the placement rod and the top surface of the placement plate. Afterwards, the user can activate the electric actuator, causing the moving plate to move towards the bearing. This allows the slider to move accordingly within the groove, causing the top plate, motor, and drive shaft to move accordingly. When one side of the slider is in contact with one side of the groove... When the inner side walls are in contact with each other, and the center point of the drive shaft is directly above the center point of the bearing, the electric push rod can be closed. At the same time, the mounting plate will be positioned on one side of the bearing, and two sets of grinding rods will be positioned on the top and bottom surfaces of the bearing, respectively, and both sets of grinding rods will be in contact with the top and bottom surfaces of the bearing. Finally, the motor can be started, so that the drive shaft, connecting plate, connecting rod, mounting plate, and two sets of grinding rods will rotate accordingly. This allows the top and bottom surfaces of the bearing to be ground simultaneously by the two sets of grinding rods, thereby improving the efficiency of bearing grinding. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To achieve the above objectives, according to Figures 1-3 As shown, the present invention provides the following technical solution: a surface grinding device for bearing processing, including a base plate 1 for placing the bearing, a placement rod 11 installed at the top of the base plate 1, and a placement plate 12 installed on the outer surface of the placement rod 11, a threaded groove 13 opened on the side surface of the placement rod 11 near the placement plate 12, and a nut 14 movably screwed onto the outer surface of the threaded groove 13, an extension plate 15 installed on the side surface of the base plate 1, and the top of the extension plate 15 being flush with the top of the base plate 1, the top of the extension plate 15 being installed with the bottom end of the side plate 17 near one side, a sliding groove 16 opened on the top surface of the extension plate 15, and one end of the sliding groove 16 extending to the top surface of the base plate 1, and further including: two sets of grinding rods 28 for grinding the inner and outer surfaces of the bearing, the two sets of grinding rods 28 being arranged vertically parallel;

[0024] One end of each of the two sets of grinding rods 28 is installed on one side of the mounting plate 27, and a connecting rod 26 is installed on the top of the mounting plate 27. A connecting plate 25 is installed on the side surface of the connecting rod 26 near the top. One end of the connecting plate 25 is installed on the side surface of the drive shaft 24. The top of the drive shaft 24 is connected to the output end of the motor 23. The motor 23 is embedded in the top plate 22. A movable plate 2 is installed at the bottom of the top plate 22, and a slider 21 is installed at the bottom of the movable plate 2. The slider 21 is located inside the slide groove 16 and is slidably connected to it.

[0025] An electric push rod 18 is used to drive the movable plate 2 to move back and forth. One end of the electric push rod 18 is installed with one side of the movable plate 2, and the other end of the electric push rod 18 is installed with one side of the side plate 17. The movable plate 2 is positioned above the base plate 1 and is positioned with one side of the placement rod 11. The drive shaft 24 is positioned above the placement rod 11, and the drive shaft 24, the connecting plate 25, and the connecting rod 26 together form a Z-shaped arrangement.

[0026] In use, the user can sleeve the bearing on the outer surface of the placement rod 11 and overlap it on the top surface of the placement plate 12. Then, the nut 14 can be movably screwed onto the outer surface of the threaded groove 13 and rotated downwards, so that the bottom surface of the nut 14 can be tightly fitted with the top surface of the bearing, thereby limiting and fixing the bearing on the outer surface of the placement rod 11 and the top surface of the placement plate 12. After that, the user can start the electric push rod 18, so that the moving plate 2 can move towards the bearing under the operation of the electric push rod 18, thereby allowing the slider 21 to move accordingly inside the slide groove 16, so that the top plate 22, motor 23 and drive shaft 24 can move accordingly. When one side surface of the slider 21 is in contact with the bearing... When the inner wall of the slide groove 16 is in contact with the bearing, and the center point of the drive shaft 24 is directly above the center point of the bearing, the electric push rod 18 can be closed. At the same time, the mounting plate 27 will be positioned on one side of the bearing, and the two sets of grinding rods 28 will be positioned on the top and bottom surfaces of the bearing, respectively, and will be in contact with the top and bottom surfaces of the bearing. Finally, the motor 23 can be started, so that the drive shaft 24, connecting plate 25, connecting rod 26, mounting plate 27, and the two sets of grinding rods 28 will rotate accordingly. This allows the top and bottom surfaces of the bearing to be ground simultaneously by the two sets of grinding rods 28, thereby improving the efficiency of bearing grinding.
