Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing outer ring grinding technology, and in particular to a bearing outer ring grinding device. Background Technology
[0002] Grinding the outer ring of a bearing is a crucial step in the bearing manufacturing process, directly impacting the bearing's precision, performance, and service life. By setting reasonable process parameters, implementing strict quality control measures, and employing scientific equipment maintenance methods, the grinding quality of the bearing's outer ring can be ensured to reach its optimal state.
[0003] Chinese patent CN220561069U discloses a bearing outer ring grinding device, relating to the field of bearing technology. The device includes a base plate, with a telescopic rod fixedly connected to the upper surface of the base plate. A suction plate is fixedly connected to the top of the telescopic rod, and the bearing outer ring body is positioned above the suction plate. This invention features a reasonable design structure. Through the cooperation between the housing, motor one, and grinding rods, during grinding, since there are two hydraulic rods, adjusting one hydraulic rod brings the outer surface of the grinding rod closer to the inner surface of the outer ring, and then adjusting the other hydraulic rod brings the outer surface of the other grinding rod closer to the outer surface of the outer ring. Simultaneously, motor one and two motors two are activated, causing the two grinding rods to rotate around the inner and outer surfaces of the bearing, while also rotating on their own axis. This solves the problem of existing bearing outer ring grinding devices, which cannot grind the inner and outer surfaces of the outer ring simultaneously, requiring more time for separate grinding and affecting bearing production efficiency.
[0004] As mentioned above, this patent provides a bearing outer ring grinding device that solves the problem that existing bearing outer ring grinding devices cannot grind the inner and outer surfaces of the outer ring simultaneously, and grinding them separately requires more time, affecting the production efficiency of bearings. However, during operation, the distance between the bearing outer ring and the grinding wheel cannot be adjusted, thus making it impossible to grind bearing outer rings of different sizes, and the overall adaptability of the grinding process still needs to be improved. Utility Model Content
[0005] This invention provides a bearing outer ring grinding device to solve the problems mentioned in the background art.
[0006] To address the aforementioned problems, this utility model provides a bearing outer ring grinding device, comprising a collecting hopper and an adjusting assembly. A left connecting baffle and a right connecting baffle are fixedly connected to the middle of the top two sides of the collecting hopper, respectively. A sliding groove is formed on the surface of the left connecting baffle. The adjusting assembly includes a fixed transmission pulley, an upper and lower adjusting pulley, and a left and right adjusting pulley. A supporting rotating shaft is fixedly connected to the surface of the upper and lower adjusting pulleys. A lifting platform is rotatably connected to the surface of the supporting rotating shaft. The surface of the lifting platform is slidably connected to the inner wall of the sliding groove. An adjusting screw is rotatably connected to the top of the lifting platform. The top of the lifting platform is located at the position of the adjusting screw. Limiting slide rods are fixedly connected to both sides; a drive shaft is fixedly connected to the surface of the fixed transmission pulley; a fixed clamping plate is fixedly connected to one side of the left connecting baffle; a grinding wheel is fixedly connected to the surface of the transmission shaft; a sliding clamping platform is rotatably connected to the surface of the left and right adjusting pulleys; a sliding rail adapted to the sliding clamping platform is opened on the surface of the fixed clamping plate; the surface of the sliding clamping platform is slidably connected to the inner wall of the sliding rail; a rotating screw is threadedly connected to the surface of the sliding clamping platform; the surfaces at both ends of the rotating screw are rotatably connected to the inner wall of the fixed clamping plate; a transmission belt is connected between the surfaces of the transmission pulley, the upper and lower adjusting pulleys, and the left and right adjusting pulleys.
[0007] Preferably: the surface of the adjusting screw is threadedly connected to the surface of the top of the left connecting baffle; the surface of the limiting slide rod is slidably connected to the surface of the top of the left connecting baffle; and the surfaces at both ends of the transmission shaft are rotatably connected to the surfaces of the left connecting baffle and the right connecting baffle, respectively.
[0008] Preferably: one end of the rotating lead screw passes through the fixed clamping plate and extends to one side of the fixed clamping plate; a rotating chuck is fixedly connected to one end of the rotating lead screw located on one side of the fixed clamping plate; a limiting clamping shaft is fixedly connected to the inner wall of the sliding clamping rail; the surface of the sliding clamping platform is slidably connected to the surface of the limiting clamping shaft.
[0009] Preferably, a filter plate is fixedly connected to the top of the collection hopper; a protective cover is fixedly connected between the top of the collection hopper and the surfaces of the left and right connecting baffles; and a curved protective cover is fixedly connected to the top of the protective cover.
[0010] Preferably: a positioning plate is fixedly connected to one end of the supporting rotating shaft; a fixing screw is fixedly connected to the surface of the positioning plate; a locking nut is threaded onto the surface of the fixing screw; a motor base is fixedly connected to the surface of the right-side connecting baffle; a motor is fixedly connected to the top of the motor base; and the output shaft of the motor is fixedly connected to one end of the transmission shaft via a coupling.
[0011] The beneficial effects of adopting the above technical solutions are:
[0012] By setting up an adjustment component, during operation, the adjustment screw rotates to drive the lifting chuck to rise and fall. This process is limited by a limit slide rod to stop the lifting chuck. The rising and falling of the lifting chuck drives the upper and lower adjustment pulleys and the support shaft to rise and fall, thereby adjusting the vertical height. At the same time, in order to ensure that the upper and lower adjustment pulleys can also transmit power while rising and falling, the rotating screw rotates to drive the sliding chuck to slide on the inner wall of the sliding rail, thereby driving the sliding chuck to adjust left and right. This causes the left and right adjustment pulleys to adjust left and right, thus keeping the transmission belt taut. This causes the transmission pulleys to rotate, driving the upper and lower adjustment pulleys and the left and right adjustment pulleys to rotate together. The whole system ensures normal transmission while also adjusting the distance between the bearing outer ring and the grinding wheel. It can grind bearing outer rings of different sizes, improving the adaptability of grinding. Attached Figure Description

[0021] like Figure 1 - Figure 4 As shown, in this embodiment, a bearing outer ring grinding device includes a collecting hopper 1 and an adjusting assembly. A left connecting baffle 2 and a right connecting baffle 3 are fixedly connected to the middle of the top two sides of the collecting hopper 1, respectively. A sliding groove 4 is formed on the surface of the left connecting baffle 2. The adjusting assembly includes a fixed transmission pulley 5, an upper and lower adjusting pulley 6, and a left and right adjusting pulley 7. A supporting rotating shaft 8 is fixedly connected to the surface of the upper and lower adjusting pulley 6. A lifting platform 9 is rotatably connected to the surface of the supporting rotating shaft 8. The surface of the lifting platform 9 is slidably connected to the inner wall of the sliding groove 4. An adjusting screw 10 is rotatably connected to the top of the lifting platform 9. Limiting devices are fixedly connected to the top of the lifting platform 9 and to both sides of the adjusting screw 10. A slide bar 11; a drive shaft 12 is fixedly connected to the surface of the fixed transmission pulley 5; a fixed clamping plate 13 is fixedly connected to one side of the left connecting baffle 2; a grinding wheel 14 is fixedly connected to the surface of the drive shaft 12; a sliding clamping platform 15 is rotatably connected to the surface of the left and right adjusting pulleys 7; a sliding rail 16 adapted to the sliding clamping platform 15 is opened on the surface of the fixed clamping plate 13; the surface of the sliding clamping platform 15 is slidably connected to the inner wall of the sliding rail 16; a rotating screw 17 is threadedly connected to the surface of the sliding clamping platform 15; the surfaces at both ends of the rotating screw 17 are rotatably connected to the inner wall of the fixed clamping plate 13; a transmission belt 18 is connected between the surfaces of the drive pulley, the upper and lower adjusting pulleys 6 and the left and right adjusting pulleys 7.
[0022] Through the above technical solution, a left connecting baffle 2 and a right connecting baffle 3 are fixed at the top of the collecting hopper 1. A sliding slot 4 is opened on the left connecting baffle 2 for slidingly placing the lifting hopper 9. The surface of the lifting hopper 9 is rotatably connected to the support shaft 8. The adjusting screw 10 is rotatably connected to the lifting hopper 9 and is also threadedly connected to the top surface of the left connecting baffle 2, so that after the adjusting screw 10 rotates, it moves up and down on the surface of the left connecting baffle 2. The drive shaft 12 rotates, driving the grinding wheel 14 to start rotating. The grinding wheel 14 is used to grind the outer ring of the bearing. The fixed plate 13 is fixed on the left connecting baffle 2, and a sliding rail 16 is opened on the surface of the fixed plate 13 to support the sliding hopper 15. The sliding hopper 15 slides on the inner wall of the sliding rail 16. The rotating screw 17 is threadedly connected to the sliding hopper 15, and after the rotating screw 17 rotates, it drives the sliding hopper 15 to move up and down. 5. During operation, the adjusting screw 10 rotates to drive the lifting platform 9 to rise and fall. This process is limited by the limiting slide rod 11. The rising and falling of the lifting platform 9 drives the upper and lower adjusting pulleys 6 and the supporting rotating shaft 8 to rise and fall, thereby adjusting the vertical height. At the same time, in order to ensure that the upper and lower adjusting pulleys 6 can be driven to move while rising and falling, the rotating screw 17 rotates to drive the sliding platform 15 to slide on the inner wall of the sliding rail 16, thereby driving the sliding platform 15 to adjust left and right, thereby causing the left and right adjusting pulleys 7 to adjust left and right, so that the transmission belt 18 is in a taut state, and then the transmission pulleys rotate to drive the upper and lower adjusting pulleys 6 and the left and right adjusting pulleys 7 to rotate together. This ensures normal transmission while adjusting the distance between the bearing outer ring and the grinding wheel 14, which can grind bearing outer rings of different sizes, improving the adaptability of grinding.
[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the surface of the adjusting screw 10 is threadedly connected to the top surface of the left connecting baffle 2; the surface of the limiting slide rod 11 is slidably connected to the top surface of the left connecting baffle 2; the surfaces of both ends of the transmission shaft 12 are rotatably connected to the surfaces of the left connecting baffle 2 and the right connecting baffle 3, respectively; one end of the rotating screw 17 passes through the fixed clamping plate 13 and extends to one side of the fixed clamping plate 13; a rotating chuck 19 is fixedly connected to one end of the rotating screw 17 located on one side of the fixed clamping plate 13; a limiting clamping shaft 20 is fixedly connected to the inner wall of the sliding clamping rail 16; and the surface of the sliding clamping platform 15 is slidably connected to the surface of the limiting clamping shaft 20.
[0024] Through the above technical solution, the adjusting screw 10 passes through to the top of the left connecting baffle 2, and the limiting slide rod 11 is slidably connected to the top of the left connecting baffle 2, so that the adjusting screw 10 rotates and rises and falls, driving the lifting platform 9 to rise and fall, and then driving the limiting slide rod 11 to slide up and down on the top of the left connecting baffle 2. The two ends of the transmission shaft 12 rotate on the surfaces of the left connecting baffle 2 and the right connecting baffle 3, while one end of the rotating screw 17 passes through to one side of the fixed plate 13. The rotating chuck 19 drives the rotating screw 17 to rotate, thereby driving the sliding platform 15 to slide on the inner wall of the sliding rail 16. The sliding platform 15 slides on the surface of the limiting shaft 20. During this process, the limiting shaft 20 limits the sliding platform 15.
[0025] like Figure 1 and Figure 3 As shown, a filter plate 21 is fixedly connected to the top of the collection hopper 1; a protective cover 22 is fixedly connected between the top of the collection hopper 1 and the surfaces of the left connecting baffle 2 and the right connecting baffle 3; a curved protective cover 23 is fixedly connected to the top of the protective cover 22; a positioning baffle 24 is fixedly connected to one end of the supporting rotating shaft 8; a fixing screw 25 is fixedly connected to the surface of the positioning baffle 24; a locking nut 26 is threadedly connected to the surface of the fixing screw 25; a motor base 27 is fixedly connected to the surface of the right connecting baffle 3; a motor 28 is fixedly connected to the top of the motor base 27; and the output shaft of the motor 28 is fixedly connected to one end of the transmission shaft 12 via a coupling.
[0026] Through the above technical solution, the filter plate 21 is fixed to the top of the collection hopper 1. The debris generated after grinding enters the collection hopper 1 through the filter plate 21 for collection. The protective cover 22 and the curved protective cover 23 prevent debris from splashing out during grinding. In addition, a positioning baffle 24 is fixed to one end of the supporting rotating shaft 8, so that the rotating shaft 8 drives the positioning baffle 24 to rotate. The fixing screw 25 is fixed to the surface of the positioning baffle 24, and the outer ring of the support bearing is placed on the fixing screw 25. The locking nut 26 rotates on the surface of the fixing screw 25, thereby fixing the outer ring of the bearing on the fixing screw 25. The positioning baffle 24 rotates while simultaneously rotating the outer ring of the bearing on the fixed screw 25. Although the upper and lower adjusting pulleys 6 and the transmission pulley rotate in opposite directions, the diameters of the upper and lower adjusting pulleys 6 and the transmission pulley can be changed, thereby changing their rotation speeds. This creates a difference in rotation speed between the outer ring of the bearing and the grinding wheel 14, resulting in relative motion between them and ensuring normal grinding. Finally, a motor base 27 is fixed to the surface of the rear connecting baffle, and a motor 28 is fixed to the top of the motor base 27. When the motor 28 is working, it can drive the transmission shaft 12 to rotate through the output shaft, thereby providing power for grinding.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate this utility model, and not to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented with existing technology.
