[0002] The outer ring groove of a deep groove ball bearing refers to the annular groove on the outer ring of a deep groove ball bearing. Its main function is to provide a rolling track for the steel ball, so that the bearing can withstand radial loads and certain axial loads. The interface radius of the outer ring groove is slightly larger than the ball radius, in an arc shape, and is located on the inner surface of the outer ring, corresponding to the inner ring groove, together forming the rolling space for the steel ball.

[0003] The groove of the outer ring of the bearing provides a precise rolling path for the steel ball. During the processing of deep groove ball bearings, the outer ring groove needs to be ground to reduce the friction and wear between the steel ball and the groove. During the processing, multiple clamps need to be operated to position the outer ring of the bearing, which is inconvenient to operate and difficult to achieve the purpose of calibrating the center of the outer ring of the bearing.

[0012] A method for using a deep groove ball bearing outer ring groove automatic grinding device, the method comprising the following steps: When grinding the outer ring groove of the deep groove ball bearing, the two multi-stage electric hydraulic rods are controlled to contract and drive the top plate to move upward. The top plate drives multiple grinding components to move upward through the box body, so that the grinding components are away from the workbench. Then, the outer ring of the bearing is placed on the workbench, and the turntable is rotated by the handle to drive the worm to rotate inside the two sleeves. The rotation of the worm can drive the worm wheel to rotate, and the worm wheel drives the driving gear to rotate counterclockwise through the bearing seat; Because the three deflection gears are meshed and connected with the same driving gear, the driving gear drives the deflection gear to rotate clockwise, so that the extension plates outside the three deflection gears can drive the three positioning blocks to approach each other, so that the positioning blocks can push the outer ring of the bearing to the middle of the workbench, and achieve the purpose of calibrating the center of the outer ring of the bearing. When the three positioning blocks are tightly fitted with the outer ring of the bearing, the turntable stops rotating. Because the worm wheel and worm transmission transmit power through the friction between the spiral surface of the worm and the tooth surface of the worm wheel, when the worm is used as the active component to drive the worm wheel, the rotational force of the worm can be smoothly transmitted to the worm wheel. If a torque is applied to the worm wheel in an attempt to reversely drive the worm through the worm wheel, the friction will hinder the transmission, resulting in the worm wheel being unable to effectively drive the worm, so the position of the positioning block can be locked, which plays a role in positioning the center of the outer ring of the bearing; After completing the locking work of the outer ring of the bearing, the two multi-stage electric hydraulic rods are controlled to extend and drive the top plate to move downward, so that the top plate drives the box body to move downward, and the box body drives the three support components and the grinding component to move downward, and the grinding component is adjusted to the position of the groove inside the outer ring of the bearing, that is, the end of the grinding tool in the grinding component is flush with the center of the groove, and the two multi-stage electric hydraulic rods are stopped at this time; By controlling the driving motor to work, the driving motor drives the support seat to rotate through the rotating seat, and the support seat drives the outer ring of the bearing to rotate through the workbench. At this time, the electric hydraulic push rod is controlled to extend and drive the hinge seat to move down inside the box body. The hinge seat can squeeze the three support rods to deflect them, and the bottom ends of the three support rods are expanded outward. The bottom ends of the support rods push the sliding rods to move, and the sliding rods drive the grinding tool to approach the groove in the outer ring of the bearing. Because the three sliding rods move synchronously, the three grinding tools can contact the inner wall of the groove at the same time. As the workbench drives the outer ring of the bearing to rotate, the grinding tool can grind the groove. The inner wall of the outer ring of the bearing is supported by multiple points, so that the outer ring of the bearing is always in the center of the workbench during the grinding process, and the load that the inner wall of the outer ring of the bearing can bear is consistent, thereby preventing the outer ring of the bearing from being easily offset from the center during grinding; The height of the articulated seat is adjusted by controlling the extension or contraction of the electric hydraulic push rod, so that the articulated seat can drive the sliding rod to move through the support rod, and the sliding rod drives the grinding tool to move horizontally, which is convenient for adjusting the position of the grinding tool to meet the grinding processing requirements of the outer rings of bearings of different specifications. After the grinding process is completed, the electric hydraulic push rod shrinks and drives the articulated seat to move upward, so that the three support rods below can drive multiple grinding tools to approach each other through the sliding rod until the grinding tool is away from the outer ring of the bearing, and the multi-stage electric hydraulic rod is controlled to shrink and drive the top plate to move upward, so that the grinding tool moves to the top of the outer ring of the bearing, and the drive motor is stopped so that the outer ring of the bearing no longer rotates; Secondly, rotate the turntable in the opposite direction, so that the turntable drives the worm wheel to rotate through the worm, and the worm wheel drives the driving gear to rotate clockwise, and the driving gear drives the three deflection gears to rotate counterclockwise, so that the deflection gear drives the positioning block away from the bearing outer ring through the extension plate, that is, the locking state of the bearing outer ring is released, and then remove the bearing outer ring from the workbench; When replacing the grinding tool, use a hexagonal wrench to turn the locking screw. After removing the locking screw, the locking state between the grinding tool and the mounting seat is released. When installing the grinding tool after replacement, push the slot in the grinding tool into the outside of the mounting seat, and the limit column on one side of the mounting seat is embedded in the limit slot in the grinding tool, which plays a role in calibrating the center of the grinding tool and the mounting seat, and then fix the grinding tool and the mounting seat with the locking screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. After the outer ring of the bearing is mounted on the workbench, the multi-stage electric hydraulic rod is extended and drives the top plate to move downward, and the box body drives the three support assemblies and the grinding assembly to move downward, and the grinding assembly is adjusted to the groove position inside the outer ring of the bearing, that is, the end of the grinding tool in the grinding assembly is flush with the center of the groove, and the driving motor drives the support seat to rotate through the rotating seat, and the support seat drives the outer ring of the bearing to rotate through the workbench. At this time, the electric hydraulic push rod is controlled to extend and drive the hinge seat to move downward inside the box body, and the hinge seat can squeeze the three support rods to deflect them, and the bottom ends of the three support rods are spread outward to support The bottom end of the rod pushes the sliding rod to move, and the sliding rod drives the grinding tool to approach the groove in the outer ring of the bearing. Because the three sliding rods move synchronously, the three grinding tools can contact the inner wall of the groove at the same time. As the workbench drives the outer ring of the bearing to rotate, the grinding tool can grind the groove. The inner wall of the outer ring of the bearing is supported at multiple points, so that the outer ring of the bearing is always in the center of the workbench during the grinding process, and the load that the inner wall of the outer ring of the bearing can withstand is consistent, thereby preventing the outer ring of the bearing from deviating from the center during grinding, and it is not easy to grind the path of the groove off-center, thereby improving the grinding accuracy.

[0014] 2. The present invention places the outer ring of the bearing on a workbench, and the turntable drives the worm to rotate inside the two sleeves. The rotation of the worm can drive the worm wheel to rotate, and the worm wheel drives the driving gear to rotate counterclockwise through the bearing seat. Since the three deflection gears are meshed and connected with the same driving gear, the driving gear drives the deflection gear to rotate clockwise, so that the extension plates outside the three deflection gears can drive the three positioning blocks to approach each other, so that the positioning blocks can push the outer ring of the bearing to move to the middle of the workbench, so as to achieve the purpose of calibrating the center of the outer ring of the bearing. When the three positioning blocks are tightly fitted with the outer ring of the bearing, the turntable stops rotating. Since the worm wheel and the worm drive The power is transmitted through the friction between the spiral surface of the worm and the tooth surface of the worm wheel, so that the worm and the worm wheel can be self-locking, so that the position of the positioning block can be locked, and the purpose of calibrating the center of the bearing outer ring is achieved, and the stability of subsequent processing is improved. When removing the bearing outer ring, the turntable is rotated in the opposite direction, so that the turntable drives the worm wheel to rotate through the worm, and the worm wheel drives the driving gear to rotate clockwise, and the driving gear drives the three deflection gears to rotate counterclockwise, so that the deflection gear drives the positioning block away from the bearing outer ring through the extension plate, and the locking state of the bearing outer ring can be released, thereby facilitating the loading and unloading of the bearing outer ring and improving the convenience of operation.

[0025] A method for using an automatic grinding device for an outer ring groove of a deep groove ball bearing, the method comprising the following steps: When grinding the outer ring groove of the deep groove ball bearing, the two multi-stage electric hydraulic rods 102 are controlled to contract and drive the top plate 101 to move upward, and the top plate 101 drives the multiple grinding assemblies 13 to move upward through the box body 11, so that the grinding assemblies 13 are away from the workbench 2. Next, the outer ring of the bearing is placed on the workbench 2, and the turntable 506 is rotated by the handle, so that the turntable 506 drives the worm 504 to rotate inside the two shaft sleeves 505. During the rotation of the worm 504, the worm wheel 503 can be driven to rotate, and the worm wheel 503 drives the driving gear 501 to rotate counterclockwise through the bearing seat 502; Because the three deflection gears 401 are meshed and connected with the same driving gear 501, the driving gear 501 drives the deflection gear 401 to rotate clockwise, so that the extension plate 403 outside the three deflection gears 401 can drive the three positioning blocks 404 to approach each other, so that the positioning blocks 404 can push the outer ring of the bearing to move to the middle of the workbench 2, so as to achieve the purpose of calibrating the center of the outer ring of the bearing. When the three positioning blocks 404 are tightly fitted with the outer ring of the bearing, the turntable 506 stops rotating. Because the transmission of the worm wheel 503 and the worm 504 is The power is transmitted through the friction between the spiral surface of the worm 504 and the tooth surface of the worm wheel 503. When the worm 504 is used as an active component to drive the worm wheel 503, the rotational force of the worm 504 can be smoothly transmitted to the worm wheel 503. If a torque is applied to the worm wheel 503 in an attempt to reversely drive the worm 504 through the worm wheel 503, the friction will hinder the transmission, resulting in the worm wheel 503 being unable to effectively drive the worm 504. Therefore, the position of the positioning block 404 can be locked, which plays a role in positioning the center of the outer ring of the bearing; After completing the locking work of the outer ring of the bearing, the two multi-stage electric hydraulic rods 102 are controlled to extend and drive the top plate 101 to move downward, so that the top plate 101 drives the box body 11 to move downward, and the box body 11 drives the three support components 12 and the grinding component 13 to move downward, and the grinding component 13 is adjusted to the position of the groove inside the outer ring of the bearing, that is, the end of the grinding tool 131 in the grinding component 13 is flush with the center of the groove, and the two multi-stage electric hydraulic rods 102 are stopped at this time; By controlling the driving motor 7 to work, the driving motor 7 drives the support seat 1 to rotate through the rotating seat 6, and the support seat 1 drives the outer ring of the bearing to rotate through the workbench 2.

The hinge seat 104 can squeeze the three support rods 122 to deflect them, and the bottom ends of the three support rods 122 are expanded outward. The bottom ends of the support rods 122 push the sliding rods 121 to move, and the sliding rods 121 drive the grinding tool 131 to approach the groove in the outer ring of the bearing. Because the three sliding rods 121 move synchronously, the three grinding tools 131 can contact the inner wall of the groove at the same time. As the workbench 2 drives the outer ring of the bearing to rotate, the grinding tool 131 can grind the groove. The inner wall of the outer ring of the bearing is supported at multiple points, so that the outer ring of the bearing is always at the center of the workbench 2 during the grinding process, and the load that the inner wall of the outer ring of the bearing can bear is consistent, thereby preventing the outer ring of the bearing from being easily offset from the center during grinding; The height of the articulated seat 104 is adjusted by controlling the electric hydraulic push rod 103 to extend or shorten, so that the articulated seat 104 can drive the sliding rod 121 to move through the support rod 122, and the sliding rod 121 drives the grinding tool 131 to move horizontally, so as to facilitate the adjustment of the position of the grinding tool 131 to meet the grinding processing requirements of the outer rings of bearings of different specifications. After the grinding processing is completed, the electric hydraulic push rod 103 shrinks and drives the articulated seat 104 to move upward, so that the three support rods 122 below can drive multiple grinding tools 131 to approach each other through the sliding rod 121, until the grinding tool 131 is away from the outer ring of the bearing, and the multi-stage electric hydraulic rod 102 is controlled to shrink and drive the top plate 101 to move upward, so that the grinding tool 131 moves to the top of the outer ring of the bearing, and the driving motor 7 is stopped so that the outer ring of the bearing no longer rotates; Secondly, the turntable 506 is rotated in the opposite direction, so that the turntable 506 drives the worm wheel 503 to rotate through the worm 504, and the worm wheel 503 drives the driving gear 501 to rotate clockwise, and the driving gear 501 drives the three deflection gears 401 to rotate counterclockwise, so that the deflection gear 401 drives the positioning block 404 away from the bearing outer ring through the extension plate 403, that is, the locking state of the bearing outer ring is released, and then the bearing outer ring is removed from the workbench 2; When replacing the grinding tool 131, use a hexagonal wrench to turn the locking screw 134. After removing the locking screw 134, the locking state between the grinding tool 131 and the mounting seat 123 is released.

3. A method for using an automatic grinding device for the outer ring groove of a deep groove ball bearing, according to the automatic grinding device for the outer ring groove of a deep groove ball bearing according to claim 2, characterized in that: The method of use comprises the following steps: When grinding the groove of the outer ring of the deep groove ball bearing, the two multi-stage electric hydraulic rods (102) are controlled to contract to drive the top plate (101) to move upward, and the top plate (101) drives the multiple grinding components (13) to move upward through the box body (11), so that the grinding components (13) are away from the workbench (2). Next, the outer ring of the bearing is placed on the workbench (2), and the turntable (506) is rotated by the handle, so that the turntable (506) drives the worm (504) to rotate inside the two shaft sleeves (505). The rotation of the worm (504) can drive the worm wheel (503) to rotate, and the worm wheel (503) drives the driving gear (501) to rotate counterclockwise through the bearing seat (502); Because the three deflection gears (401) are meshed and connected with the same driving gear (501), the driving gear (501) drives the deflection gear (401) to rotate clockwise, so that the extension plate (403) outside the three deflection gears (401) can drive the three positioning blocks (404) to approach each other, so that the positioning blocks (404) can push the outer ring of the bearing to move to the middle of the workbench (2), so as to achieve the purpose of calibrating the center of the outer ring of the bearing. When the three positioning blocks (404) are tightly fitted with the outer ring of the bearing, the turntable (506) stops rotating. Because the worm wheel (503) and the worm (504) drive The power is transmitted through the friction between the spiral surface of the worm (504) and the tooth surface of the worm wheel (503). When the worm (504) is used as an active component to drive the worm wheel (503), the rotational force of the worm (504) can be smoothly transmitted to the worm wheel (503). If a torque is applied to the worm wheel (503) in an attempt to reversely drive the worm (504) through the worm wheel (503), the friction will hinder the transmission, resulting in the worm wheel (503) being unable to effectively drive the worm (504). Therefore, the position of the positioning block (404) can be locked, thereby playing a role in positioning the center of the outer ring of the bearing; After the locking operation of the outer ring of the bearing is completed, the two multi-stage electric hydraulic rods (102) are controlled to extend and drive the top plate (101) to move downward, so that the top plate (101) drives the box body (11) to move downward, and the box body (11) drives the three support assemblies (12) and the grinding assembly (13) to move downward, and the grinding assembly (13) is adjusted to a position aligned with the groove inside the outer ring of the bearing, that is, the end of the grinding tool (131) in the grinding assembly (13) is flush with the center of the groove, and at this time, the two multi-stage electric hydraulic rods (102) are stopped from working; By controlling the driving motor (7) to work, the driving motor (7) drives the supporting seat (1) to rotate through the rotating seat (6), and the supporting seat (1) drives the outer ring of the bearing to rotate through the workbench (2). At this time, the electric hydraulic push rod (103) is controlled to extend and drive the hinge seat (104) to move downward inside the box body (11). The hinge seat (104) can squeeze the three supporting rods (122) to deflect them, and the bottom ends of the three supporting rods (122) are spread outward. The bottom ends of the supporting rods (122) push the sliding rods (121) to move, and the sliding rods (121) The grinding tool (131) is driven to approach the groove in the outer ring of the bearing. As the three sliding rods (121) move synchronously, the three grinding tools (131) can contact the inner wall of the groove at the same time. As the workbench (2) drives the outer ring of the bearing to rotate, the grinding tool (131) can grind the groove. The inner wall of the outer ring of the bearing is supported at multiple points, so that the outer ring of the bearing is always at the center of the workbench (2) during the grinding process, and the load that the inner wall of the outer ring of the bearing can bear is consistent, thereby preventing the outer ring of the bearing from being easily offset from the center during grinding. The height of the articulated seat (104) is adjusted by controlling the electric hydraulic push rod (103) to extend or shorten, so that the articulated seat (104) can drive the sliding rod (121) to move through the support rod (122), and the sliding rod (121) drives the grinding tool (131) to move horizontally, so as to facilitate the adjustment of the position of the grinding tool (131) and meet the grinding processing requirements of the outer rings of bearings of different specifications. After the grinding processing is completed, the electric hydraulic push rod (103) contracts and drives the articulated seat (104) to move upward, so that the three support rods (122) below can drive the plurality of grinding tools (131) to move closer to each other through the sliding rod (121) until the grinding tools (131) are away from the outer ring of the bearing, and the multi-stage electric hydraulic rod (102) is controlled to contract and drive the top plate (101) to move upward, so that the grinding tool (131) moves to the top of the outer ring of the bearing, and the driving motor (7) is stopped so that the outer ring of the bearing no longer rotates; Secondly, the rotating disk (506) is rotated in the opposite direction, so that the rotating disk (506) drives the worm wheel (503) to rotate through the worm (504), and the worm wheel (503) drives the driving gear (501) to rotate clockwise, and the driving gear (501) drives the three deflection gears (401) to rotate counterclockwise, so that the deflection gear (401) drives the positioning block (404) away from the bearing outer ring through the extension plate (403), that is, the locking state of the bearing outer ring is released, and then the bearing outer ring is removed from the workbench (2); When replacing the grinding tool (131), the locking screw (134) is rotated with a hexagonal wrench. After the locking screw (134) is removed, the locking state between the grinding tool (131) and the mounting seat (123) is released. When installing the grinding tool (131) after replacement, the clamping groove (132) in the grinding tool (131) is pushed into the outside of the mounting seat (123), and the limiting column (124) on one side of the mounting seat (123) is embedded in the limiting groove (133) in the grinding tool (131), which plays a role in calibrating the center of the grinding tool (131) and the mounting seat (123). Then, the grinding tool (131) and the mounting seat (123) are fixed by the locking screw (134).
