Description

Technical Field

[0001] The invention relates to the technical field of bearing production and processing, and in particular to a bearing ring grinding device for bearing production and processing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. According to the friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Both are widely used in mechanical equipment.

[0003] The patent with the patent announcement number CN221337832U discloses a bearing ring production device for bearing production and processing, including a processing table and a base, the base is fixedly connected to the bottom of the processing table, a dust removal device is arranged above the processing table, and a grinding device is arranged on the upper surface of the processing table, and the grinding device includes a rotating unit, a clamping unit and a grinding unit. The bearing ring production device for bearing production and processing, when grinding the bearing ring, starts the rotating motor to drive the rotating shaft to rotate inside the fixed bearing, thereby driving the turntable and the bearing ring outside it to rotate, so that the inner and outer sides are grinded by the grinding unit, thereby improving the efficiency of the grinding process, and when grinding the inner and outer walls of the bearing ring, starts the dust suction fan, and uses the dust suction hood to suck out the debris dust generated during grinding, and transmits it to the dust storage bin inside the dust suction fan through the dust suction pipe, so as to avoid the debris dust from overflowing and affecting the health of the processing personnel.

[0004] However, the device still has some shortcomings: the device can grind the bearing rings, but certain adjustments are required before grinding for bearing rings of different diameters. At the same time, the bearing rings are prone to shaking due to the high-speed rotation of the grinder during grinding, which can easily cause deviations from the pre-set grinding position of the bearing ring and cause uneven grinding thickness of the bearing ring. Summary of the invention

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a bearing ring grinding device for bearing production and processing, comprising a top seat, a cabinet assembly is arranged at the bottom of the top seat, a grinding table is arranged at the center of the top of the top seat, a support column is arranged at the corner of the top of the top seat, a circular plate is arranged at the top of the support column, a motor is arranged at the top of the circular plate, an electric telescopic rod is arranged at the bottom of the circular plate, the top of the fixed end of the electric telescopic rod is fixedly connected to the output end of the motor, and a grinding disc is arranged at the bottom of the telescopic end of the electric telescopic rod; The grinding table is provided with an anti-deviating device at the periphery, an anti-adhesion device is provided inside the anti-deviating device, and an anti-wear device is provided inside the anti-adhesion device; The anti-deviation device includes two L-shaped arc top plates, the bottom of the two L-shaped arc top plates passes through one end near the center of the top seat and is symmetrically slidably installed inside the grinding table, a guide arc plate is fixedly installed on the side of the L-shaped arc top plate close to the grinding table, a sliding groove is provided on the end of the guide arc plate close to the grinding table, an elastic telescopic rod is fixedly installed inside the guide arc plate, a rubber block is fixedly installed on the telescopic end of the elastic telescopic rod close to the grinding table, a turntable is rotatably installed inside the bottom end of the L-shaped arc top plate, a number of resistance plates are equidistantly and fixedly installed on the front side of the turntable, an L-shaped hollow plate is fixedly installed on the inner wall of the L-shaped arc top plate away from the grinding table, and two shielding plates are symmetrically and hingedly connected at the bottom edge of the circular plate through a torsion spring.

[0007] According to the above technical solution, a spring is arranged between the L-shaped arc top plate and the inside of the grinding table, and the L-shaped arc top plate is of hollow design, the rubber soft block is located inside the guide arc plate slide groove, and the rubber soft block is convex on the arc surface of the outer wall of the guide arc plate, the outer wall of the turntable contacts with the top of the top seat, the bottom end of the L-shaped hollow plate is located on the movement trajectory of the resistance plate, and the shielding plate is located on the movement trajectory of the L-shaped arc top plate. When the bearing ring to be ground is placed up and down on the grinding table, the outer wall of the bearing ring contacts with the arc surface at the top of the L-shaped arc top plate to generate a resistance force. At this time, the L The L-shaped arc top plate extends outward from the inside of the grinding table through the resistance force, and the outer wall of the L-shaped arc top plate is always in contact with the outer wall of the bearing ring through the limit of the spring. As the bearing ring goes deeper, the outer wall of the bearing ring contacts the arc surface of the outer wall of the guide arc plate. At this time, the bearing ring continues to move downward through the arc surface of the guide arc plate. During this process, the bearing ring will contact the rubber soft block, and the rubber soft block will be deformed by the extrusion thrust of the bearing ring, and move along the guide arc plate slide groove away from the center of the grinding table until it fits with the outer wall of the guide arc plate. The rubber soft block pushes the elastic telescopic rod to extend and retract. The ends of the L-shaped arc top plate contract synchronously, and the elastic telescopic rod causes the outer wall of the rubber soft block to always fit the outer wall of the bearing ring until the bearing ring is placed on the top of the grinding table, and the motor is started. The output end of the motor drives the electric telescopic rod to rotate, and the telescopic end of the electric telescopic rod drives the grinding disc to move downward and fit the top of the bearing ring for grinding; the L-shaped arc top plate will resist the shielding plate during the movement away from the center of the grinding table, and the hinge shaft at the top of the shielding plate will start to rotate. At this time, the shielding plate starts to move in an arc trajectory with the hinge shaft as the axis, and the shielding plate is distributed above the periphery of the grinding table in an inclined posture, The grinding debris is blocked to a certain extent, and at the same time, the L-shaped arc top plate drives the turntable to slide and rub synchronously along the top of the top seat. The turntable rotates inside the L-shaped arc top plate through friction, and the rotation of the turntable drives the contact plate to rotate. During the revolution of the contact plate, the bottom end of the L-shaped hollow plate is contacted to cause it to bend. After that, the contact plate and the L-shaped hollow plate are guided by an arc surface to facilitate the contact plate to pass over the curved part at the bottom of the L-shaped hollow plate. When the L-shaped hollow plate is reset by its own toughness, it will swing back and forth to generate vibration, and the transmission of force causes the guide arc plate and the rubber soft block to vibrate slightly.

[0008] According to the above technical scheme, the anti-adhesion device includes a U-shaped telescopic frame, a square frame and a vacuum cleaner. The top of the U-shaped telescopic frame is hinged to the top of the circular plate by a torsion spring, and the U-shaped telescopic frame has a built-in spring. The square frame is slidably installed on the outer wall of the baffle plate away from the center of the circular plate by a spring, and the outer wall of the square frame is hinged to the bottom of the telescopic end of the U-shaped telescopic frame. The outer wall of the vacuum cleaner is fixedly installed inside the square frame. When the baffle plate moves upward in an arc trajectory, it drives the square frame to move synchronously, and the square frame drives the vacuum cleaner to move synchronously. At the same time, the square frame is limited by the telescopic end of the U-shaped telescopic frame. Therefore, in the process of the square frame moving in an arc trajectory, the hinge shaft of the U-shaped telescopic frame starts to rotate. At this time, the telescopic end of the U-shaped telescopic frame will push the square frame to slide downward along the outer wall of the baffle plate, and the square frame drives the vacuum cleaner to move synchronously.

[0009] According to the above technical solution, the anti-adhesion device also includes a number of pull plates, a through rod, an arc plate, a number of vertical plates and a friction wheel. The tops of the several pull plates are symmetrical and hinged on the side of the shielding plate close to the center of the circular plate. Both ends of the through rod are fixedly installed on the side of the pull plate close to the center of the square frame. The top of the arc plate is hinged to the top of the outer wall of the square frame close to the center of the circular plate. The tops of the several vertical plates are symmetrical and fixedly installed at the bottom edge of the square frame. The friction wheel is rotatably installed on the outer wall of the vertical plate away from the center of the square frame.

[0010] According to the above technical solution, a torsion spring is arranged between the top of the pull plate and the shielding plate, the arc plate is penetrated inside and rotatably installed on the outer wall of the through rod, the outer wall of the friction wheel is in contact with the outer wall of the shielding plate, and the square frame drives the arc plate to move synchronously when the square frame moves downward. During the downward movement of the arc plate, the arc plate is limited by the through rod, and the through rod is limited by the pull plate, causing the hinge axis between the arc plate itself and the through rod to start rotating. Therefore, as the square frame continues to move downward, the hinge axis between the arc plate and the square frame starts to rotate, and drives the arc plate to flip upward with the hinge axis as the axis. At the same time, the square frame drives the vertical plate to move synchronously, and the vertical plate drives the friction wheel to slide and rub synchronously along the outer wall of the shielding plate, and the friction wheel starts to rotate along the outer wall of the vertical plate through friction.

[0011] According to the above technical scheme, the anti-wear device includes a reciprocating screw, a plurality of Z-plates and a telescopic magnetic plate. Both ends of the reciprocating screw are fixedly installed on the side of the friction wheel close to the center of the square frame. The interiors of the plurality of Z-plates are penetrated and movably installed on the outer wall of the reciprocating screw. The top of the Z-plate is slidably connected to the bottom of the square frame. The bottom of the telescopic magnetic plate is fixedly installed on the top of the Z-plate close to the grinding disk. The top of the telescopic end of the telescopic magnetic plate contacts the bottom of the grinding disk. When the baffle plate moves upward in an arc trajectory, it drives the square frame to move synchronously, and the square frame drives the vacuum cleaner to move synchronously. At the same time, the square frame is limited by the telescopic end of the U-shaped telescopic frame. Therefore, in the process of the square frame moving in an arc trajectory, the hinge shaft of the U-shaped telescopic frame starts to rotate. At this time, the telescopic end of the U-shaped telescopic frame will push the square frame to slide downward along the outer wall of the baffle plate, and the square frame drives the vacuum cleaner to move synchronously.

[0012] According to the above technical scheme, the anti-wear device also includes a plurality of receiving mesh plates, U-shaped clamps, semicircular blocks, receiving frames and arcuate blocks. The bottoms of the plurality of receiving mesh plates are symmetrically hinged on the outer wall of the Z-shaped plate near the center of the circular plate. The inner wall of the top of the U-shaped clamp is slidably installed on the outer wall of the receiving mesh plate through a spring. The top of the semicircular block is fixedly installed on the bottom of the U-shaped clamp. The top of the receiving frame is fixedly installed on the bottom of the vertical plate near one end of the friction wheel. The bottom of the arcuate block is fixedly installed on the bottom of the inner wall of the receiving frame.

[0013] According to the above technical scheme, torsion springs are arranged between the bottom of several receiving mesh plates and the Z-shaped plates, and the outer wall of the arc block is located on the arc motion trajectory of the semicircular block. When the square frame moves downward, it drives the arc plate to move synchronously. During the downward movement of the arc plate, it is limited by the through rod, and the through rod is limited by the pulling plate, which causes the hinge axis between the arc plate itself and the through rod to start rotating. Therefore, as the square frame continues to move downward, the hinge axis between the arc plate and the square frame starts to rotate, and drives the arc plate to flip upward with the hinge axis as the axis. At the same time, the square frame drives the vertical plate to move synchronously, and the vertical plate drives the friction wheel to slide and rub synchronously along the outer wall of the shielding plate, and the friction wheel starts to rotate along the outer wall of the vertical plate through friction.

[0014] The present invention provides a bearing ring grinding device for bearing production and processing. It has the following beneficial effects: (1) The present invention sets an anti-deviating device, and cooperates with an L-shaped arc top plate, a guide arc plate, an elastic telescopic rod, a rubber block, a turntable, a contact plate, an L-shaped hollow plate and a shielding plate. The L-shaped arc top plate is used to realize adaptive clamping of bearing rings of different specifications and diameters. At the same time, the friction between the guide arc plate and the rubber block gradually increases as the bearing ring goes deeper downward, thereby effectively improving the stability of the bearing ring on the top of the grinding table, preventing the bearing ring from shaking due to the high-speed rotation of the grinding disk during grinding, causing deviations in the pre-set grinding position of the bearing ring, and avoiding uneven grinding thickness of the bearing ring; and relying on vibration force, the guide arc plate and the rubber block are used to effectively reduce the pulling force of the bearing ring when it descends, thereby enhancing the smoothness of the bearing ring when it descends, thereby avoiding unilateral tilting between the bearing ring and the grinding table, and at the same time enabling the rubber block to better fit the outer wall of the bearing ring, thereby improving stability.

[0015] (2) The present invention provides an anti-adhesion device, and cooperates with a shielding plate, a U-shaped telescopic frame, a square frame, a vacuum cleaner, a pull plate, a through rod, a curved plate, a vertical plate and a friction wheel to cause the vacuum cleaner to shorten the distance between itself and the grinding table when the bearing ring grinding work starts, and adjust its own suction angle at the same time to absorb the debris caused by the grinding of the bearing ring at the optimal angle, and collect the debris in a centralized manner through an external dust collecting bag of the vacuum cleaner to prevent the debris from being scattered and attached to the top of the grinding disk or the outer wall of the workpiece, thereby reducing the grinding accuracy; and effectively expand the guiding angle and drainage range of the curved plate to prevent the grinding debris sucked by the vacuum cleaner from overflowing, and at the same time rely on the curved surface drainage of the curved plate to accelerate the gas circulation rate around the vacuum cleaner, thereby improving the vacuum cleaner's absorption effect on debris and preventing excessive debris from colliding with each other and falling.

[0016] (3) The present invention adopts the setting of anti-wear device, and cooperates with friction wheel, reciprocating screw rod, Z-plate, telescopic magnetic plate, receiving mesh plate, U-shaped clamp plate, semicircular block, receiving frame and arc surface block. The reciprocating scraping of the telescopic end of the telescopic magnetic plate and the revolution of the grinding disc effectively remove the grinding debris remaining from the bottom of the grinding disc during the previous processing. The telescopic magnetic plate adsorbs the magnetic debris of the bearing ring to prevent the secondary falling and adhesion phenomenon, effectively improves the cleanliness of the bottom of the grinding disc, and avoids the bearing ring being damaged due to the grinding of debris carried by the grinding disc. The U-shaped clamp plate clamps the receiving mesh plate to enable the receiving mesh plate to swing back and forth, thereby swinging and guiding the magnetic debris collected inside the receiving mesh plate and falling from the surface of the telescopic magnetic plate, so that the debris at the top part of the receiving mesh plate continues to fall downward, extending the cleaning cycle of the receiving mesh plate and preventing the accumulation of excessive debris at the top part of the receiving mesh plate, thereby increasing the risk of falling.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-Figure 8 , one embodiment of the present invention is: a bearing ring grinding device for bearing production and processing, comprising a top seat 1, a cabinet assembly 2 is arranged at the bottom of the top seat 1, a grinding table 21 is arranged at the center of the top of the top seat 1, a support column 22 is arranged at the corner of the top of the top seat 1, a circular plate 23 is arranged at the top of the support column 22, a motor is arranged at the top of the circular plate 23, an electric telescopic rod 3 is arranged at the bottom of the circular plate 23, the top of the fixed end of the electric telescopic rod 3 is fixedly connected to the output end of the motor, and a grinding disc 31 is arranged at the bottom of the telescopic end of the electric telescopic rod 3; An anti-deviating device 4 is disposed on the periphery of the polishing table 21, an anti-adhesion device 5 is disposed inside the anti-deviating device 4, and an anti-wear device 6 is disposed inside the anti-adhesion device 5; The anti-deviating device 4 comprises two L-shaped arc top plates 41, the bottom of the two L-shaped arc top plates 41 is passed through and symmetrically slidably installed inside the grinding table 21 near the center of the top seat 1, a guide arc plate 42 is fixedly installed on the side of the L-shaped arc top plate 41 near the grinding table 21, a slide groove is provided on the end of the guide arc plate 42 near the grinding table 21, an elastic telescopic rod 43 is fixedly installed inside the guide arc plate 42, a rubber soft block 44 is fixedly installed on the telescopic end of the elastic telescopic rod 43 near the grinding table 21, a turntable 45 is rotatably installed inside the bottom end of the L-shaped arc top plate 41, a plurality of resistance plates 46 are equidistantly and fixedly installed on the front of the turntable 45, an L-shaped hollow plate 47 is fixedly installed on the inner wall of the L-shaped arc top plate 41 away from the grinding table 21, and two shielding plates 48 are symmetrically and hingedly connected at the bottom edge of the circular plate 23 through a torsion spring.

[0021] A spring is arranged between the L-shaped arc top plate 41 and the inside of the grinding table 21, and the L-shaped arc top plate 41 is hollow in design, the rubber soft block 44 is located inside the guide arc plate 42 slide groove, and the rubber soft block 44 protrudes from the arc surface of the outer wall of the guide arc plate 42, the outer wall of the turntable 45 contacts the top of the top seat 1, the bottom end of the L-shaped hollow plate 47 is located on the movement track of the resistance plate 46, and the shielding plate 48 is located on the movement track of the L-shaped arc top plate 41. Through the above cooperation, the L-shaped arc top plate 41 is relied on to realize adaptive clamping of bearing rings of different specifications and diameters, and at the same time, the guide arc plate 42 and the rubber soft block 44 are continuously moved downward as the bearing ring moves downward. The friction force gradually increases, which effectively improves the stability of the bearing ring on the top of the grinding table 21, prevents the bearing ring from shaking due to the high-speed rotation of the grinding disc 31 during grinding, causing deviations in the pre-set grinding direction of the bearing ring, and avoids the occurrence of uneven grinding thickness of the bearing ring; through the above cooperation, the vibration force is used to enable the guide arc plate 42 and the rubber soft block 44 to effectively reduce the pulling force when the bearing ring descends, thereby enhancing the smoothness of the bearing ring when it descends, thereby avoiding unilateral tilting between the bearing ring and the grinding table 21, and at the same time enabling the rubber soft block 44 to better fit the outer wall of the bearing ring, thereby improving stability.

[0022] During use, when the bearing ring to be polished is placed downward from the top of the polishing table 21, the outer wall of the bearing ring contacts the arc surface of the top of the L-shaped arc top plate 41, thereby generating a resistance force. At this time, the L-shaped arc top plate 41 extends outward from the inside of the polishing table 21 through the resistance force, and the outer wall of the L-shaped arc top plate 41 is always in contact with the outer wall of the bearing ring through the limiting of the spring. As the bearing ring goes deeper, the outer wall of the bearing ring contacts the arc surface of the outer wall of the guide arc plate 42. At this time, the bearing ring continues to move downward through the arc surface of the guide arc plate 42. During this process, the bearing ring will contact the rubber soft block 44, and the rubber soft block 44 will be deformed by the extrusion thrust of the bearing ring, and move along the guide arc plate 42 slide groove away from the center of the polishing table 21 until it contacts the guide arc plate 42. The outer wall of the arc plate 42 fits in, and the rubber soft block 44 pushes the telescopic end of the elastic telescopic rod 43 to shrink synchronously. The elastic telescopic rod 43 causes the outer wall of the rubber soft block 44 to always fit the outer wall of the bearing ring until the bearing ring is placed on the top of the grinding table 21. The motor is started, and the output end of the motor drives the electric telescopic rod 3 to rotate. The telescopic end of the electric telescopic rod 3 drives the grinding disc 31 to move downward and fit the top of the bearing ring for grinding. Through the above cooperation, the L-shaped arc top plate 41 is relied on to realize adaptive clamping of bearing rings of different specifications and diameters. At the same time, the guide arc plate 42 and the rubber soft block 44 cause the friction force to gradually increase as the bearing ring continues to move downward, which effectively improves the stability of the bearing ring on the top of the grinding table 21 and prevents the bearing ring from being damaged during grinding. The high-speed rotation of the grinding disc 31 causes shaking, resulting in deviations in the pre-set bearing ring grinding orientation, thereby avoiding uneven grinding thickness of the bearing ring; the L-shaped arc top plate 41 will contact the baffle plate 48 during the movement away from the center of the grinding table 21, and the hinge shaft at the top of the baffle plate 48 begins to rotate. At this time, the baffle plate 48 begins to move in an arc-shaped trajectory with the hinge shaft as the axis. The baffle plate 48 is distributed above the outer periphery of the grinding table 21 in an inclined posture to block the grinding debris to a certain extent. At the same time, the L-shaped arc top plate 41 drives the turntable 45 to slide and rub synchronously along the top of the top seat 1. The turntable 45 rotates inside the L-shaped arc top plate 41 through friction. When the turntable 45 rotates, it drives the resistance plate 46 to rotate, and the resistance plate 46 revolves During the process, the bottom end of the L-shaped hollow plate 47 is contacted to cause it to bend, and then the arc surface guide between the contact plate 46 and the L-shaped hollow plate 47 facilitates the contact plate 46 to pass over the bottom curved part of the L-shaped hollow plate 47. When the L-shaped hollow plate 47 is reset by its own toughness, it will swing back and forth to generate vibration, and the transmission of force causes the guide arc plate 42 and the rubber soft block 44 to vibrate slightly. Through the above cooperation, the vibration force is used to effectively reduce the pulling force of the bearing ring when it descends, thereby enhancing the smoothness of the bearing ring when it descends, thereby avoiding unilateral tilting between the bearing ring and the grinding table 21, and at the same time causing the rubber soft block 44 to better fit the outer wall of the bearing ring to improve stability.

[0023] See also Figure 1-Figure 8, based on the above embodiment, another embodiment of the present invention further includes an anti-adhesion device 5; The anti-adhesion device 5 includes a U-shaped telescopic frame 51, a square frame 52 and a vacuum cleaner 53. The top of the U-shaped telescopic frame 51 is hinged to the top of the circular plate 23 by a torsion spring. The U-shaped telescopic frame 51 has a built-in spring. The square frame 52 is slidably installed on the outer wall of the baffle plate 48 away from the center of the circular plate 23 by a spring. The outer wall of the square frame 52 is hinged to the bottom of the telescopic end of the U-shaped telescopic frame 51. The outer wall of the vacuum cleaner 53 is fixedly installed inside the square frame 52. Through the above cooperation, the vacuum cleaner 53 is prompted to shorten the distance between it and the grinding table 21 at the beginning of the bearing ring grinding work, and at the same time adjust its own suction angle to absorb the debris caused by the grinding of the bearing ring at the optimal angle, and collect the debris through the external dust bag of the vacuum cleaner 53 to prevent the debris from being scattered and attached to the top of the grinding disk 31 or the outer wall of the workpiece, thereby reducing the grinding accuracy.

[0024] The anti-adhesion device 5 also includes a plurality of pull plates 54, a through rod 55, an arc plate 56, a plurality of vertical plates 57 and a friction wheel 58. The tops of the plurality of pull plates 54 are symmetrical and hinged on the side of the shielding plate 48 close to the center of the circular plate 23. Both ends of the through rod 55 are fixedly installed on the side of the pull plate 54 close to the center of the square frame 52. The top of the arc plate 56 is hinged on the top of the outer wall of the square frame 52 close to the center of the circular plate 23. The tops of the plurality of vertical plates 57 are symmetrical and fixedly installed at the bottom edge of the square frame 52. The friction wheel 58 is rotatably installed on the outer wall of the vertical plate 57 away from the center of the square frame 52.

[0025] A torsion spring is arranged between the top of the pull plate 54 and the baffle plate 48, and the arc plate 56 penetrates inside and is rotatably installed on the outer wall of the through rod 55. The outer wall of the friction wheel 58 contacts the outer wall of the baffle plate 48. The above coordination effectively expands the guiding angle and drainage range of the arc plate 56 to prevent the grinding debris sucked by the vacuum cleaner 53 from overflowing. At the same time, the arc surface drainage of the arc plate 56 accelerates the gas circulation rate around the vacuum cleaner 53, thereby improving the vacuum cleaner 53's absorption effect on the debris and preventing excessive debris from colliding with each other and falling.

[0026] When in use, the baffle plate 48 moves upward in an arc trajectory, driving the square frame 52 to move synchronously, and the square frame 52 drives the vacuum cleaner 53 to move synchronously. At the same time, the square frame 52 is limited by the telescopic end of the U-shaped telescopic frame 51. Therefore, during the movement of the square frame 52 in an arc trajectory, the hinge axis of the U-shaped telescopic frame 51 starts to rotate. At this time, the telescopic end of the U-shaped telescopic frame 51 will push the square frame 52 to slide downward along the outer wall of the baffle plate 48, and the square frame 52 drives the vacuum cleaner 53 to move synchronously. Through the above cooperation, the vacuum cleaner 53 is prompted to shorten the distance between it and the grinding table 21 at the beginning of the bearing ring grinding work, and at the same time adjust its own suction angle to absorb the debris caused by the grinding of the bearing ring at the optimal angle, and collect the debris through the external dust bag of the vacuum cleaner 53 to prevent the debris from scattering and adhering to the top of the grinding disc 31 or the outer wall of the workpiece, thereby reducing the grinding accuracy; when the square frame 52 moves downward, it drives the arc plate 56 to move synchronously, and the arc During the downward movement of the curved plate 56, it is limited by the through rod 55, and the through rod 55 is limited by the pulling plate 54, which causes the hinge axis between the curved plate 56 and the through rod 55 to start to rotate. Therefore, as the square frame 52 continues to move downward, the hinge axis between the curved plate 56 and the square frame 52 starts to rotate, and drives the curved plate 56 to flip upward with the hinge axis as the axis. At the same time, the square frame 52 drives the vertical plate 57 to move synchronously, and the vertical plate 57 drives the friction wheel 58 to slide and rub synchronously along the outer wall of the baffle plate 48. The friction wheel 58 starts to rotate along the outer wall of the vertical plate 57 due to the friction force. The above cooperation effectively expands the guiding angle and drainage range of the curved plate 56 to prevent the grinding debris sucked by the vacuum cleaner 53 from overflowing. At the same time, the curved surface drainage of the curved plate 56 accelerates the gas circulation rate around the vacuum cleaner 53, thereby improving the vacuum cleaner 53 The effect of absorbing debris to prevent excessive debris from colliding with each other and falling.

[0027] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-wear device 6; The anti-wear device 6 includes a reciprocating screw 61, a plurality of Z-shaped plates 62 and a telescopic magnetic plate 63. Both ends of the reciprocating screw 61 are fixedly mounted on one side of the friction wheel 58 close to the center of the square frame 52. The interior of the plurality of Z-shaped plates 62 penetrates and is movably mounted on the outer wall of the reciprocating screw 61. The top of the Z-shaped plate 62 is slidably connected to the bottom of the square frame 52. The bottom of the telescopic magnetic plate 63 is fixedly mounted on the top of one end of the Z-shaped plate 62 close to the grinding disc 31. The top of the telescopic end of the telescopic magnetic plate 63 contacts the bottom of the grinding disc 31. Through the above cooperation, the vacuum cleaner 53 is prompted to shorten the distance between it and the grinding table 21 at the beginning of the bearing ring grinding work, and at the same time adjusts its own suction angle to absorb the debris caused by the grinding of the bearing ring at the optimal angle, and collects the debris in a centralized manner through the external dust bag of the vacuum cleaner 53 to prevent the debris from being scattered and attached to the top of the grinding disc 31 or the outer wall of the workpiece, thereby reducing the grinding accuracy.

[0028] The anti-wear device 6 also includes a plurality of receiving mesh plates 64, a U-shaped clamp plate 65, a semicircular block 66, a receiving frame 67 and a curved block 68. The bottoms of the plurality of receiving mesh plates 64 are symmetrically hinged on the outer wall of the Z-shaped plate 62 near the center of the circular plate 23. The top inner wall of the U-shaped clamp plate 65 is slidably installed on the outer wall of the receiving mesh plate 64 through a spring. The top of the semicircular block 66 is fixedly installed on the bottom of the U-shaped clamp plate 65. The top of the receiving frame 67 is fixedly installed on the bottom of the vertical plate 57 near one end of the friction wheel 58. The bottom of the curved block 68 is fixedly installed on the bottom of the inner wall of the receiving frame 67.

[0029] Torsion springs are provided between the bottom of the receiving mesh plates 64 and the Z-shaped plates 62. The outer wall of the arc block 68 is located on the arc motion trajectory of the semicircular block 66. The above coordination effectively expands the guiding angle and drainage range of the arc plate 56 to prevent the grinding debris sucked by the vacuum cleaner 53 from overflowing. At the same time, the arc drainage of the arc plate 56 accelerates the gas circulation rate around the vacuum cleaner 53, thereby improving the vacuum cleaner 53's absorption effect on the debris and preventing excessive debris from colliding with each other and falling.

[0030] When in use, the friction wheel 58 rotates and drives the reciprocating screw rod 61 to rotate. When the reciprocating screw rod 61 rotates, the reciprocating spiral groove on its outer wall limits the built-in block of the Z-shaped plate 62, driving the Z-shaped plate 62 to slide back and forth horizontally and reset along the bottom of the square frame 52. The Z-shaped plate 62 drives the telescopic magnetic plate 63 to slide back and forth horizontally and reset along the bottom of the grinding disc 31 before the grinding work starts. The telescopic end of the telescopic magnetic plate 63 is set with a built-in spring to make itself always fit the bottom of the grinding disc 31. At the same time, the motor drives the grinding disc 31 to start the slow start. The grinding disc 31 rotates slowly for one circle. Through the above cooperation, the reciprocating scraping of the telescopic end of the telescopic magnetic plate 63 and the revolution of the grinding disc 31 can effectively remove the grinding debris remaining from the last processing at the bottom of the grinding disc 31. The telescopic magnetic plate 63 adsorbs the magnetic debris of the bearing ring to prevent secondary shedding and adhesion, effectively improving the cleanliness of the bottom of the grinding disc 31 and preventing the grinding disc 31 from carrying debris and easily causing damage to the bearing ring; when the Z-shaped plate 62 moves horizontally, it drives the receiving mesh plate 64 to move synchronously, and the receiving mesh plate 64 drives the U-shaped clamping plate 65 to move synchronously. The plate 65 drives the semicircular block 66 to move horizontally, and contacts with the outer wall of the arc block 68 and generates a resistance force. The arc block 68 is kept stationary by the limit of the receiving frame 67. With the continuous movement of the U-shaped clamping plate 65, the resistance force between the semicircular block 66 and the arc block 68 gradually increases. At this time, the arc block 68 pushes the semicircular block 66 to generate an upward force through the arc guide. The semicircular block 66 causes the U-shaped clamping plate 65 to be synchronously stressed and slide upward along the outer wall of the receiving mesh plate 64. At this time, the hinge shaft of the receiving mesh plate 64 starts to rotate and drives the receiving mesh plate 64 to rotate. The mesh plate 64 swings toward the direction close to the telescopic magnetic plate 63, and then the receiving mesh plate 64 is reset by the torsion spring and repeats this process. The above cooperation relies on the clamping of the receiving mesh plate 64 by the U-shaped clamp plate 65, so that the receiving mesh plate 64 can swing back and forth, thereby swinging and guiding the magnetic debris collected inside the receiving mesh plate and falling from the surface of the telescopic magnetic plate 63, so that the debris at the top part of the receiving mesh plate 64 continues to fall downward, extending the cleaning cycle of the receiving mesh plate 64 while preventing excessive accumulation of debris at the top part of the receiving mesh plate 64, thereby increasing the risk of falling.
