Description

Technical Field

[0001] This utility model relates to the field of bearing ring production technology, and in particular to a grinding device for bearing ring production. Background Technology

[0002] Bearing rings are the core component of rolling bearings. Through precisely designed raceways, they guide the rolling elements to achieve low-friction rotation. Bearing rings are widely used in automotive engines, wind turbine main shafts, industrial robot joints, and other applications. Their performance directly affects the reliability and lifespan of the equipment, making them a key basic component of modern machinery industry. The development of bearing rings began with human exploration of rolling friction. As early as ancient China, wooden roller support structures appeared. Domestic technology has broken the monopoly in fields such as aircraft landing gear and aero engines, becoming a core component of high-end equipment, and continues to evolve towards self-reliance and green technology.

[0003] In the prior art, bearings need to be polished during production, and dry polishing is commonly used. However, the frictional heat generated during polishing is difficult to dissipate, which can easily cause thermal deformation of precision components such as bearing rings, affecting machining accuracy. The high coefficient of friction between the grinding tool and the workpiece during dry polishing leads to increased cutting resistance, which reduces polishing efficiency and shortens the life of the polishing blade. The metal dust generated by dry polishing cannot be effectively captured, which not only pollutes the working environment but also easily deposits on equipment guide rails, bearings, and transmission systems. Therefore, in order to solve the above problems, this utility model proposes a polishing device for bearing ring production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a grinding device for bearing ring production. Clean water is introduced into the inner cavity of the housing, and a drive motor drives the grinding blades to grind the inner cavity of the bearing in the water. The water absorbs the grinding heat in time, preventing bearing deformation. The water reduces the coefficient of friction, improves grinding efficiency, extends the service life of the grinding blades, and the water captures dust, thereby reducing wear on the equipment and bearings, lowering the failure rate and improving the yield.

[0005] This utility model provides the following technical solution: a grinding device for bearing ring production, comprising a housing, two hydraulic rods fixedly installed on the upper part of the housing, symmetrically distributed on the left and right, a lifting plate fixedly installed on the telescopic end of the hydraulic rods, a drive motor fixedly installed on the upper part of the lifting plate, the output shaft of the drive motor being movably connected to the lifting plate, a rotating block fixedly connected to the output shaft of the drive motor via a coupling, a servo motor fixedly installed on the right side of the rotating block, a threaded rod fixedly connected to the output shaft of the servo motor via a coupling, the threaded rod being movably connected to the inner cavity of the rotating block, a slider movably connected to the threaded rod, a connecting rod fixedly installed at the bottom of the slider, and a grinding blade fixedly installed at the bottom end of the connecting rod. The drive motor drives the grinding blade to grind the bearing inner cavity in water. The water absorbs heat in time to prevent bearing deformation, reduces the coefficient of friction to improve grinding efficiency, and captures dust to reduce wear on equipment and bearings, thereby reducing the failure rate and improving the yield rate.

[0006] Preferably, waterproof electric actuators are symmetrically fixedly installed on the left and right sides of the inner cavity of the housing. Clamping plates are fixedly installed on the telescopic ends of the waterproof electric actuators. The bearing ring is placed in the inner cavity of the housing, and the clamping plates are driven by the telescopic ends of the waterproof electric actuators to clamp and fix the bearing ring, thereby improving the stability of the bearing during grinding.

[0007] Preferably, valve one is fixedly installed on the left side of the box, valve two is fixedly installed on the right side of the box, and a cover plate is movably connected to the front of the box via a shaft. Before grinding, valve one is opened to introduce clean water into the inner cavity of the box. After grinding, valve two can be opened to drain the water. The accumulated impurities at the bottom of the inner cavity of the box can be cleaned by opening the cover plate, ensuring the cleaning efficiency of the device.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] Water is introduced into the inner cavity of the housing. The hydraulic rod lifts the plate to position the grinding blade in the inner cavity of the bearing ring. A servo motor drives the grinding blade to contact the inner surface of the bearing cavity. The drive motor then uses the grinding blade to grind the inner cavity of the bearing in the water. The efficient cooling characteristics of the water medium can instantly absorb the frictional heat generated during the grinding process, preventing the bearing from undergoing surface hardening, changes in microstructure, or thermal deformation due to local overheating. The lubricating effect of the water reduces the coefficient of friction between the grinding blade and the bearing, greatly reducing cutting resistance, which helps to improve grinding efficiency and extend the service life of the grinding blade. The water medium can capture grinding dust, avoiding occupational hazards such as silicosis, while reducing dust wear on equipment and bearings, and lowering the equipment failure rate. In addition, the buffering effect of water can effectively absorb high-frequency vibration energy, making the grinding pressure distribution more uniform and improving the yield of bearings after grinding.
