Description

Technical Field

[0001] The invention relates to the technical field of bearing production equipment, and in particular to an inner ring grinding device used for bearing manufacturing. Background Art

[0002] Bearings are components used in mechanical equipment to support and guide rotating or moving parts. Their main functions are to reduce friction, carry loads and maintain the relative position of parts. Bearings are usually composed of an inner ring, an outer ring, rolling elements (such as balls or rollers) and a cage. When bearings are produced, there will be a lot of burrs on the inner ring, so the burrs need to be removed by a grinding device.

[0003] For example, in the Chinese patent application number 202410819312.9, a bearing inner ring grinding device and method are provided, in which an outer wall clamping block and an inner wall clamping block are simultaneously arranged on a first mounting frame, and are alternately clamped on the inner wall and outer wall of the bearing inner ring, so that the inner wall and outer wall grinding work are completed successively, simplifying the processing flow of the bearing inner ring and greatly improving the processing efficiency of the bearing inner ring.

[0004] However, the grinding wheel of this type of grinding device is in direct and close contact with the inner wall of the inner ring of the bearing during the grinding process. This results in the coolant not being able to completely contact the grinding wheel when spraying the coolant, causing the coolant to not be sprayed on the grinding part, making the cooling effect worse. If the grinding operation is stopped for cooling, it will affect production efficiency.

[0005] To this end, we propose an inner ring grinding device for bearing manufacturing. Summary of the invention

[0043] Furthermore, the cooling assembly 6 includes a rotating shaft 61 rotatably connected to the mounting plate 51 through a bearing, a fixing bar 62 is fixed to the bottom end of the rotating shaft 61, and the fixing bar 62 is fixed to the top of the fixing block 53. A motor 2 64 for driving the rotating shaft 61 to rotate is fixed to the mounting plate 51. A grinding plate 2 63 is fixed to the side of the fixing block 53 away from the grinding plate 1 54. A nozzle 65 is provided on the back side of the grinding plate 2 63 on the U-shaped frame 501. A barrel 66 is fixed to the frame 1. A liquid pump 67 is fixed to the frame 1. The liquid inlet end of the liquid pump 67 is connected to the barrel 66 through a connecting pipe, and the liquid outlet end of the liquid pump 67 is connected to the nozzle 65 through a hose 1 68.

[0044] Furthermore, the scraping assembly 7 includes a rectangular plate 71 arranged in the U-shaped frame 501, a brush 72 is fixed to one side of the rectangular plate 71 close to the grinding plate 2 63, a main bevel gear 73 is fixed to the outer surface of the rotating shaft 61, a secondary bevel gear 74 is meshed on the outer surface of the main bevel gear 73, a rotating rod 75 is fixed at the axis of the secondary bevel gear 74, the rotating rod 75 is rotatably connected to the mounting plate 51 through a bearing, a turntable 76 is fixed to the end of the rotating rod 75 away from the secondary bevel gear 74, a push rod 77 is fixed on the turntable 76, a movable shell 78 is slidably provided on the outer surface of the push rod 77, a connecting strip 79 is fixed on the movable shell 78, and the bottom end of the connecting strip 79 is fixedly connected to the rectangular plate 71.

[0045] Furthermore, the scraping assembly 7 also includes a limiting strip 710 fixed on the top of the U-shaped frame 501 , and a limiting block 711 is fixed on the connecting strip 79 , and the limiting block 711 slides on the outer surface of the limiting strip 710 .

[0046] When in use, the bearing is placed in the placement groove opened on the top of the placement shell 12, and the bearing is locked by a fixing device, which can be composed of a screw and a clamping block. After the bearing is locked, the mounting frame 2, the connecting strip 3 and the L-shaped frame 4 are driven downward by the cylinder to move the grinding plate 54 into the placement groove, and the connecting block 50 is slid in the L-shaped frame 4 by screwing the screw 52, ​​so that the mounting plate 51 can be moved, and the grinding plate 54 is close to the inner ring of the bearing, so that it is suitable for bearings of different sizes. After adjustment, the screw 52 is screwed into different threaded holes to lock the connecting block 50. At the same time, the motor 55 is driven to drive the connecting strip 3 and the L-shaped frame 4 to rotate, so that the grinding plate 54 rotates together to grind the inner ring of the bearing. This is the existing technology, so it will not be described in detail here.

[0047] Considering that the grinding plate 54 needs to be cooled down due to the increase in temperature after continuous grinding, but the grinding plate 54 is in direct and close contact with the inner wall of the inner ring of the bearing during operation, the coolant cannot be completely in contact with the grinding plate 54 when the coolant is sprayed, resulting in the coolant not being sprayed to the grinding part, making the cooling effect worse, and if the grinding operation is stopped for cooling, it will affect the production efficiency. Now the following improvements are made:

[0048] Through the setting of motor 2 64, in the later stage of grinding, when the surface temperature of grinding plate 1 54 rises, motor 2 64 can be started to drive the rotating shaft 61 and the fixed bar 62 to rotate, thereby driving the fixed block 53, grinding plate 1 54 and grinding plate 2 63 to rotate, so that the positions of grinding plate 1 54 and grinding plate 2 63 are interchanged, and grinding is carried out using grinding plate 2 63, while grinding plate 1 54 is moved to the position corresponding to nozzle 65, and by starting the liquid pump 67, the coolant in the barrel 66 is pumped into the nozzle 65 through the connecting pipe and hose 1 68, and is sprayed out from the nozzle 65, thereby cooling the surface of grinding plate 1 54.

[0049] A further advantage of adopting the above method is that grinding plate 2 63 is used instead of grinding plate 1 54 for grinding, and grinding plate 1 54 is kept away from the inner wall of the bearing for cooling, so as to avoid the coolant from not being sprayed on the grinding part, which would make the cooling effect worse, and there is no need to stop the grinding operation to stop cooling, thereby improving production efficiency.

[0050] It should be noted that a PLC controller can be installed on the frame 1, the PLC controller is electrically connected to the motor 2 64 and the liquid pump 67, and the motor 2 64 and the liquid pump 67 can be started intermittently by setting the time to achieve automatic control.

[0051] Considering that a large amount of dust and impurities will adhere to the surface of the grinding plate 54 after grinding, when the coolant is sprayed onto the surface of the grinding plate 54, the dust and impurities will affect the contact between the coolant and the surface of the grinding plate 54, thereby affecting the cooling effect. The following improvements are now made:

[0052] The brush 72 is arranged on the rectangular plate 71 and the brush 72, and in the process of grinding plate 1 54 rotating to the grinding plate 2 63 position, part of the dust can be scraped off through the contact between the grinding plate 1 54 and the brush 72, thereby reducing the dust adhering to the surface of the grinding plate 1 54, and the main bevel gear 73 is connected to the rotating shaft 61 through the main bevel gear 73. When the rotating shaft 61 rotates, the main bevel gear 73 and the secondary bevel gear 74 are also driven to rotate, and the secondary bevel gear 74 drives the rotating rod 75 and the rotating disk 76 to rotate, and the rotating disk 76 drives the push rod 77 to perform a circular motion, and the limit block 711 slides on the outer surface of the limit bar 710 for limiting, thereby driving the movable shell 78 and the connecting bar 79 to move left and right, and the connecting bar 79 drives the brush 72 and the rectangular plate 71 to move left and right together, so that the friction between the grinding plate 1 54 and the brush 72 can be increased, so that the dust can be removed more cleanly, and the contact effect between the coolant and the surface of the grinding plate 1 54 is improved, thereby improving the cooling effect.

[0053] Example 2, refer to Figure 1-Figure 9 , an inner ring grinding device for bearing manufacturing, comprising a frame 1, a collecting shell 11 is fixed on the frame 1, a placing shell 12 is fixed on the top of the collecting shell 11, a placing groove is opened on the placing shell 12, a mounting frame 2 is arranged above the placing shell 12, a connecting bar 3 is rotated on the mounting frame 2 through a bearing, a cylinder for driving the mounting frame 2 to rise and fall is fixed on the top of the placing shell 12, L-shaped frames 4 are fixed on both sides of the connecting bar 3, and a grinding component 5 is arranged on the L-shaped frame 4, and also includes:

[0054] A cooling component 6 is arranged on the grinding component 5, and the cooling component 6 is used to cool the grinding component 5;

[0055] A scraping assembly 7 mounted on the cooling assembly 6, the scraping assembly 7 is used to remove impurities and dust on the grinding assembly 5 before cooling;

[0056] A vibration assembly 8 is arranged on the scraping assembly 7, and the vibration assembly 8 is used to vibrate the grinding assembly 5;

[0057] The auxiliary component 9 is installed on the grinding component 5, and the auxiliary component 9 is used to make the grinding component 5 swing.

[0058] Furthermore, the vibration assembly 8 includes a sliding rod 81 that slides in the rectangular plate 71, an arc block 82 is fixed to one end of the sliding rod 81 away from the rectangular plate 71, a reset member 83 is arranged between the arc block 82 and the rectangular plate 71, the reset member 83 and the sliding rod 81 are both slidably connected to the U-shaped frame 501, a rectangular bar 85 is fixed to the U-shaped frame 501 through an L-shaped rod 84, a force-bearing rod 86 is fixed to a side array of the rectangular bar 85 close to the arc block 82, and a rubber head 87 is fixed to one end of the sliding rod 81 away from the arc block 82.

[0059] Furthermore, the reset member 83 includes a liquid storage cylinder 831 fixed on the rectangular plate 71, a moving rod 832 slides inside the liquid storage cylinder 831, one end of the moving rod 832 away from the liquid storage cylinder 831 is fixedly connected to the arc block 82, and a spring 833 is sleeved on the outer surface of the moving rod 832, and both ends of the spring 833 are respectively fixedly connected to the arc block 82 and the liquid storage cylinder 831.

[0060] It should be noted that: the slide bar 81 is slidably connected to the rectangular plate 71. When the rectangular plate 71 moves left and right, the slide bar 81 and the arc block 82 are also driven to move left and right. Since the position of the arc block 82 corresponds to the force rod 86, and since the rectangular bar 85 and the force rod 86 are fixed, when the arc block 82 moves, it will be squeezed by the force rod 86 and move backward, thereby driving the moving rod 832 to slide backward in the liquid storage cylinder 831, squeezing the spring 1 833, and the slide bar 81 The rubber head 87 is driven to move backward, and when the arc block 82 moves to a point where it is no longer in contact with the force-bearing rod 86, the elastic force of the spring 833 will reset the slide bar 81 and the rubber head 87. Therefore, the movement of the rectangular plate 71 will drive the slide bar 81 and the rubber head 87 to move intermittently, and the slide bar 81 and the rubber head 87 will appropriately impact the grinding plate 54. Through the setting of the rubber head 87, when the grinding plate 54 is impacted, the surface wear of the grinding plate 54 caused by hard contact can be avoided.

[0061] A further benefit of adopting the above method is that when the scraping component 7 scrapes the dust and impurities on the surface of the grinding plate 54, the grinding plate 54 can be impacted simultaneously, and the grinding plate 54 can be vibrated by the impact. The vibration can help loosen and remove the dust and impurities on the surface of the grinding plate 54, so that the dust can be removed more cleanly, ensuring that the surface of the grinding plate 54 remains clean, thereby further improving the cooling effect.

[0062] It should be noted that the size of the secondary bevel gear 74 needs to be smaller than that of the primary bevel gear 73 , so that when the primary bevel gear 73 rotates half a circle, it can drive the secondary bevel gear 74 to rotate many circles, thereby driving the rectangular plate 71 and the brush 72 to move intermittently.

[0063] Example 3, refer to Figure 1-Figure 9, an inner ring grinding device for bearing manufacturing, comprising a frame 1, a collecting shell 11 is fixed on the frame 1, a placing shell 12 is fixed on the top of the collecting shell 11, a placing groove is opened on the placing shell 12, a mounting frame 2 is arranged above the placing shell 12, a connecting bar 3 is rotated on the mounting frame 2 through a bearing, a cylinder for driving the mounting frame 2 to rise and fall is fixed on the top of the placing shell 12, L-shaped frames 4 are fixed on both sides of the connecting bar 3, and a grinding component 5 is arranged on the L-shaped frame 4, and also includes:

[0064] A cooling component 6 is arranged on the grinding component 5, and the cooling component 6 is used to cool the grinding component 5;

[0065] A scraping assembly 7 mounted on the cooling assembly 6, the scraping assembly 7 is used to remove impurities and dust on the grinding assembly 5 before cooling;

[0066] A vibration assembly 8 is arranged on the scraping assembly 7, and the vibration assembly 8 is used to vibrate the grinding assembly 5;

[0067] The auxiliary component 9 is installed on the grinding component 5, and the auxiliary component 9 is used to make the grinding component 5 swing.

[0068] Furthermore, the auxiliary component 9 includes a piston plate 91 fixed to the end of the moving rod 832 away from the arc block 82, the piston plate 91 slides in the liquid storage cylinder 831, the liquid storage cylinder 831 is connected with a hose 92, a fixed cylinder 93 is fixed on the U-shaped frame 501, the end of the hose 92 away from the liquid storage cylinder 831 is connected to the fixed cylinder 93, a piston plate 94 slides in the fixed cylinder 93, and an extrusion rod 95 is fixed to the bottom of the piston plate 94, and the extrusion rod 95 is connected to the fixed cylinder 93. The fixed cylinder 93 is slidably connected, a horizontal bar 96 is provided below the extrusion rod 95, a spring 97 is sleeved on the outer surface of the extrusion rod 95, and the two ends of the spring 97 are respectively fixedly connected to the piston disk 94 and the fixed cylinder 93, an adjusting block 98 is fixed on the horizontal bar 96, the nozzle 65 is fixed on a side of the adjusting block 98 away from the horizontal bar 96, a horizontal bar 99 is fixed on the U-shaped frame 501, the adjusting block 98 rotates on the outer surface of the horizontal bar 99, and a blowing part 90 is provided on the adjusting block 98.

[0069] Furthermore, the blowing part 90 includes a hose three 901 connected to the fixed cylinder 93, a rectangular shell 902 is fixed to the top of the adjusting block 98, one end of the hose three 901 away from the fixed cylinder 93 is connected to the rectangular shell 902, and an air outlet 903 is opened on a side of the rectangular shell 902 close to the grinding plate 2 63.

[0070] The piston plate 1 91 is connected to the moving rod 832. When the arc block 82 and the moving rod 832 are squeezed by the force rod 86 and move backward in the liquid storage cylinder 831, the piston plate 1 91 will also be driven to move together in the liquid storage cylinder 831, squeezing the liquid in the liquid storage cylinder 831, so that the liquid enters the fixed cylinder 93 through the hose 2 92. Since the piston plate 2 94 slides in the fixed cylinder 93, when the piston plate 2 94 is squeezed by the fluid, it will slide downward in the fixed cylinder 93, thereby driving the squeezing rod 95 to slide downward, pressing the spring 2 97. When the extrusion rod 95 moves down to contact the cross bar 96, since the adjustment block 98 is rotatably connected to the cross bar 99, the extrusion of the extrusion rod 95 will drive the cross bar 96, the adjustment block 98 and the nozzle 65 to flip upward. When the piston plate 91 is reset, the elastic force of the spring 97 will also drive the adjustment block 98 and the nozzle 65 to reset. Therefore, the movement of the piston plate 91 can drive the nozzle 65 to swing up and down, thereby increasing the spraying range of the nozzle 65, improving the contact effect between the coolant and the surface of the grinding plate 54, and further improving the cooling effect.

[0071] It is connected to the fixed cylinder 93 through the hose three 901. When the piston disc two 94 moves downward, it will squeeze the gas in the fixed cylinder 93, so that the gas enters the rectangular shell 902 through the hose three 901 and is ejected from the air outlet 903.

[0072] This design can not only blow off the dust and impurities adhering to the surface of the grinding plate 54 through air blowing, but also help to distribute the coolant more evenly, ensuring that the surface of the grinding plate 54 is better cooled.

[0073] It should be noted that the position of the nozzle 65 is not limited to the middle of the U-shaped frame 501, and its number is not limited to one group. It is sufficient to spray the coolant onto the surface of the grinding plate 1 54 before the grinding plate 1 54 moves to the position of the grinding plate 2 63.

[0074] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
