[0023] 2. The bearing outer surface grinding equipment for bearing processing is to put the bearing blank on the surface of the cylinder, and use the bottom end of the bearing blank to fit with the end of the bending support extending to the outside of the cylinder. The bearing blank can be lifted by the bending support, and the bearing blank can be preliminarily positioned, which is not easy to be skewed or offset.
[0024] 3. The bearing outer surface grinding equipment used for bearing processing uses the tip of the conical block facing downward so that the tip of the conical block is inserted between the bent supports evenly distributed inside the cylinder, and as the conical block continues to move downward, the bent supports are pushed outward by the conical surface of the conical block, so that the bent supports can slide outward, and the elastic strip is stretched, and the top pressure of the support end at the top of the bent support is utilized, and the anti-skid layer can fit the inner side of the bearing blank to play an anti-skid role, so that the bearing blank can be fixed, thereby positioning the bearing blank.

[0026] 5. The bearing outer surface grinding equipment used for bearing processing can drive the base shell to move upward by contracting the extended end of the hydraulic cylinder, so that the auxiliary component can be moved upward as a whole. As the cone block moves away from the bending support, the driving force on the bending support disappears, and under the elastic pulling force of the elastic strip, the bending support moves toward the inside of the cylinder for reset, so that the top pressure on the bearing disappears, the bearing is loosened, which is convenient for unloading the bearing, and helps to replace the bearing blank again, which is conducive to mass production.
[0027] 6. The bearing outer surface grinding equipment used for bearing processing moves downward as the base shell as a whole, and the bottom end of the elastic telescopic air pipe is installed at the top of the air hole, so that the elastic telescopic air pipe is pulled downward, and the elastic telescopic air pipe can be elastically contracted, so that the elastic telescopic air pipe is elastically deformed and stretched, thereby facilitating the downward movement of the base shell and preventing the structures from getting stuck.
[0028] 7. The bearing outer surface grinding equipment used for bearing processing uses a toggle tooth to apply a toggle force to the bottom end of the force-bearing tooth, so that the circular slide rail drives the rolling wheel to rotate in a circle, and the rolling wheel can be used to roll the circular hose. As the circular hose is squeezed by the rolling wheel, the air inside the circular hose is compressed, and combined with the control of the gas flow direction by the gas one-way valve, the squeezed air in the circular hose enters the elastic telescopic air pipe, and blows air from the air hole to the surface of the grinding bearing blank inside the base shell. The dust and chips generated by the grinding of the bending grinding teeth are blown away by the air flow, and the dust and chips are removed, which is not easy to cause scratches on the outer surface of the bearing.

[0049] The second embodiment is based on the first embodiment. Figures 1 to 8As shown:
[0050] A driving mechanism 4, which is used to carry the bearing blank and drive the bearing blank to rotate, and the driving mechanism 4 is installed in the middle of the top of the machine body 1;
[0051] Among them, the driving mechanism 4 includes a servo motor 41 and a first sleeve 42. The servo motor 41 is installed in the middle of the top of the inner cavity of the body 1. The first sleeve 42 is fixedly connected to the middle of the top of the body 1. A rotating table 43 is rotatably installed at the center of the first sleeve 42. The central axis of the bottom of the rotating table 43 is fixedly installed with the output end of the servo motor 41 through a coupling. A cylinder 44 is fixedly installed at the center of the top of the rotating table 43, and a support assembly 45 is installed in the middle of the cylinder 44.
[0052] The cylinder 44 is installed just below the base shell 32 . The central axis of the bottom of the rotating table 43 passes through the center of the first sleeve 42 . The rotating table 43 is installed just above the servo motor 41 .
[0053] The support assembly 45 includes a square hole 451 and a bending support member 452. The square hole 451 is opened in the middle of the outer cylindrical surface of the cylinder 44. The bending support member 452 is slidably installed between the square hole 451 and the cylinder 44. An elastic strip 453 is fixedly installed between the groove on the surface of the bending support member 452 and the outer cylindrical surface of the cylinder 44. A card groove 454 is opened at the bending part of the top of the bending support member 452. The support end of the surface of the bending support member 452 is fixedly connected with an anti-slip layer 455. The staff puts the bearing blank on the surface of the cylinder 44, and uses the bottom end of the bearing blank to fit with the end of the bending support member 452 extending to the outside of the cylinder 44, so that the bearing blank can be lifted by the bending support member 452, and the bearing blank can be preliminarily positioned.
[0054] There are three square holes 451, and the three square holes 451 are evenly opened on the outer cylindrical surface of the cylinder 44. The surface of the bent support 452 fits with the inner side surface of the square hole 451. The base shell 32 is driven to move downward by the extension of the telescopic end of the hydraulic cylinder 31, and the auxiliary component 33 as a whole moves downward with the base shell 32. The tip of the conical block 334 is pointed downward, so that the tip of the conical block 334 is inserted between the bent support members 452 evenly distributed inside the cylinder 44, and as the conical block 334 continues to move downward, the bent support member 452 is pushed outward by the conical surface of the conical block 334, so that the bent support member 452 can slide outward, and the elastic strip 453 is stretched, and the support end top pressure at the top of the bent support member 452 is used, and the anti-slip layer 455 can fit with the inner side surface of the bearing blank to play an anti-slip role, so the bearing blank can be fixed.
[0055] The staff turns on the servo motor 41 to work, and uses the rotation of the output end of the servo motor 41 and the connection with the first sleeve 42 to make the rotating table 43 rotate smoothly, so that the cylinder 44 can rotate with the rotating table 43, and the inner wall of the bearing blank is supported and fixed in combination with three evenly distributed bent support members 452, so that the bearing blank is driven to rotate, and the base shell 32 is sleeved on the surface of the bearing blank, and the bent grinding teeth 35 are fitted with the surface of the bearing blank, so that the surface of the bearing blank can be ground, and the bearing blank can rotate along the central axis, while the base shell 32 and the bent grinding teeth 35 do not rotate, so that the grinding force on the bearing blank is balanced.
[0056] The surface of the elastic strip 453 is a curved surface. There are three elastic strips 453, and the three elastic strips 453 are evenly installed on the outer cylindrical surface of the cylinder 44. The position of the elastic strip 453 corresponds to the position of the bending support 452. As the grinding of the outer surface of the bearing is completed, the hydraulic cylinder 31 can be used as a power again. By contracting the extended end of the hydraulic cylinder 31, the base shell 32 can be driven to move upward, so that the auxiliary component 33 can be moved upward as a whole. As the conical block 334 moves away from the bending support 452, the driving force on the bending support 452 disappears, and under the elastic pulling force of the elastic strip 453, the bending support 452 moves toward the inside of the cylinder 44 for reset, so that the top pressure on the bearing disappears, the bearing is loosened, the bearing is easy to unload, and it is helpful to replace the bearing blank again.
[0057] The third embodiment is based on the first and second embodiments. Figures 1 to 10 As shown:
[0058] A blowing mechanism 5 is installed at the top of the inner cavity of the body 1. The blowing mechanism 5 includes an annular shell 51 and a ball head base 52. The top of the annular shell 51 is fixedly connected to the middle of the top of the inner cavity of the body 1, and the annular shell 51 is installed at the position of the hydraulic cylinder 31. The top of the ball head base 52 is fixedly connected to the top of the inner cavity of the body 1 by screws. A gas one-way valve 53 is installed on the side of the top of the annular shell 51. A circular slide rail 54 is slidably installed at the ball head end of the bottom of the ball head base 52. A force-bearing tooth 55 is fixedly connected to the bottom of the circular slide rail 54. A circular hose 56 is fixedly installed in the inner cavity of the annular shell 51. The gas one-way valve The air outlet at the bottom of 53 is connected to the air inlet at the top of the circular hose 56. A rolling wheel 57 is rotatably installed on the surface of the circular slide rail 54 through a bracket. An elastic telescopic air pipe 58 is connected between the air outlet at the bottom of the circular hose 56 and the top of the air hole 36. As the base shell 32 moves downward as a whole, the bottom end of the elastic telescopic air pipe 58 is installed at the top of the air hole 36, so that the elastic telescopic air pipe 58 is subjected to a downward pulling force, and the elastic telescopic air pipe 58 can be elastically contracted, so that the elastic telescopic air pipe 58 is elastically deformed and stretched, thereby facilitating the downward movement of the base shell 32.
[0059] By inserting the triangular stopper 335 between two adjacent bending support members 452 and driving the bending support member 452 to rotate with the cylinder 44, the connecting rod 332 can be rotated, and the toggle tooth 333 will rotate with the connecting rod 332. The toggle tooth 333 is used to apply a toggle force to the bottom end of the force-bearing tooth 55, and the circular slide rail 54 is slidably supported by the ball head base 52, so that the circular slide rail 54 drives the rolling wheel 57 to rotate in a circle, and the rolling wheel 57 can be used to rotate. 7 The circular hose 56 is rolled. As the circular hose 56 is squeezed by the rolling wheel 57, the air inside the circular hose 56 is compressed. Combined with the control of the gas flow direction by the gas one-way valve 53, the squeezed air in the circular hose 56 enters the elastic telescopic air pipe 58, and blows air from the air hole 36 to the surface of the grinding bearing blank inside the base shell 32. The dust and grinding chips generated by the grinding of the bent grinding teeth 35 are blown away by the air flow, and the dust and grinding chips are removed.
[0060] The rolling wheel 57 is embedded in the annular shell 51 at a side away from the side where the rolling wheel 57 is embedded in the circular slide rail 54 . The annular shell 51 and the circular slide rail 54 are concentric circles.
[0061] When in use, the staff first puts the bearing blank on the surface of the cylinder 44, and uses the bottom end of the bearing blank to fit with the end of the bent support 452 extending to the outside of the cylinder 44, so that the bearing blank can be lifted by the bent support 452, and the bearing blank can be preliminarily positioned;
[0062] The staff starts the hydraulic cylinder 31 to work, and uses the extension of the telescopic end of the hydraulic cylinder 31 to drive the base shell 32 to move downward, so that the bent grinding teeth 35 move with the base shell 32, and the positions of the base shell 32 and the bent grinding teeth 35 can be adjusted. As the base shell 32 moves downward as a whole, the bottom end of the elastic telescopic air pipe 58 is installed at the top of the air hole 36, so that the elastic telescopic air pipe 58 is pulled downward, and the elastic telescopic air pipe 58 can be elastically contracted, so that the elastic telescopic air pipe 58 is elastically deformed and stretched, thereby facilitating the downward movement of the base shell 32.
[0063] By extending the telescopic end of the hydraulic cylinder 31, the base shell 32 is driven to move downward, and the auxiliary component 33 as a whole moves downward with the base shell 32. With the tip of the conical block 334 facing downward, the tip of the conical block 334 is inserted between the bent support members 452 evenly distributed inside the cylinder 44, and as the conical block 334 continues to move downward, the bent support member 452 is pushed outward by the conical surface of the conical block 334, so that the bent support member 452 can slide outward, and the elastic strip 453 is stretched, and the top pressure of the support end at the top of the bent support member 452 is utilized, and the anti-skid layer 455 can fit the inner side of the bearing blank to play an anti-skid role, so that the bearing blank can be fixed;
[0064] At the same time, the staff turns on the servo motor 41 to work, and uses the rotation of the output end of the servo motor 41 and the connection with the first sleeve 42 to make the rotating table 43 rotate smoothly, so that the cylinder 44 can rotate with the rotating table 43, and the inner wall of the bearing blank is supported and fixed in combination with three evenly distributed bending support members 452, so that the bearing blank is driven to rotate, and the base shell 32 is sleeved on the surface of the bearing blank, and the bent grinding teeth 35 are fitted with the surface of the bearing blank, so that the surface of the bearing blank can be ground, and the bearing blank is rotated along the central axis, while the base shell 32 and the bent grinding teeth 35 do not rotate, so that the grinding force on the bearing blank is balanced;
[0065] The triangular stopper 335 is inserted between two adjacent bent support members 452, and the bent support member 452 is rotated as the cylinder 44 drives the connected round rod 332 to rotate, and the toggle tooth 333 rotates with the connected round rod 332. The toggle tooth 333 is used to apply a toggle force to the bottom end of the force-bearing tooth 55, and the circular slide rail 54 is slidably supported by the ball head base 52, so that the circular slide rail 54 drives the rolling wheel 57 to rotate in a circle, and the rolling wheel 57 can be used to rotate. The circular hose 56 is rolled by the rolling wheel 57. As the circular hose 56 is squeezed by the rolling wheel 57, the air inside the circular hose 56 is compressed. Combined with the control of the gas flow direction by the gas check valve 53, the squeezed air in the circular hose 56 enters the elastic telescopic air delivery pipe 58 and blows air from the air hole 36 to the surface of the grinding bearing blank inside the base shell 32. The dust and grinding debris generated by the grinding of the bent grinding teeth 35 are blown away by the blowing of the air flow, and the dust and grinding debris are removed.
[0066] Moreover, as the grinding of the outer surface of the bearing is completed, the hydraulic cylinder 31 can be used as a power again. By contracting the extended end of the hydraulic cylinder 31, the base shell 32 can be driven to move upward, and the auxiliary component 33 can be moved upward as a whole. As the conical block 334 moves away from the bending support 452, the driving force on the bending support 452 disappears, and under the elastic pulling force of the elastic strip 453, the bending support 452 moves toward the inside of the cylinder 44 for reset, so that the top pressure on the bearing disappears, the bearing is loosened, the bearing is easy to unload, and it is helpful to replace the bearing blank again.
