Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and more specifically, to a bearing inner ring groove grinding and dressing device. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. During the production and processing of bearings, grinding equipment is needed to grind their inner rings.

[0003] Existing technologies disclose some patent documents related to bearing inner ring grinding. Chinese patent application number CN202122111198.9 discloses a bearing inner ring grinding device, including a housing. A first motor is fixedly installed on the left side of the connecting plate, and an electric telescopic rod is fixedly installed on the right side of the connecting plate. A grinding disc is movably installed on the outer surface of the rotating shaft. A second motor is fixedly installed at the bottom of the inner cavity of the housing. A first arc-shaped locking block is fixedly installed on one side of each of the two L-shaped fixing blocks. A second arc-shaped locking block is movably installed on the top of the first arc-shaped locking block. This bearing inner ring grinding device uses the second motor, in conjunction with a forward lead screw, a reverse lead screw, a threaded block, and the L-shaped fixing blocks, to move the first and second arc-shaped locking blocks towards the center and fix the outer ring of the bearing. Then, the electric telescopic rod, in conjunction with the first motor and the rotating shaft, drives the grinding disc to move to the right, grinding the inner ring of the bearing, thus achieving the purpose of fixing the bearing.

[0004] In the aforementioned patent, when grinding the inner ring of a bearing, it is impossible to grind both the inner and outer surfaces of the bearing inner ring simultaneously, resulting in low efficiency in grinding the bearing inner ring. To address this, we propose a bearing inner ring groove grinding and finishing device. Summary of the Invention

[0026] 3. Beneficial effects

[0027] Compared with the prior art, the advantages of this invention are:

[0028] (1) When this device is needed, first place the bearing inner ring body between the two clamping plates, then start the output end of the second motor to rotate. The output end of the second motor rotates the double-acting screw, and the rotation of the double-acting screw simultaneously drives the two nuts to move on the surface of the double-acting screw. When the double-acting screw rotates forward, the two nuts move towards the same end at the same time. The movement of the nuts drives the clamping plates to move, so that the two clamping plates clamp and fix the bearing inner ring body. The two clamping plates fix the side of the bearing inner ring body. After the clamping plates are fixed, the second motor can be turned off. At this time, the fixing of the bearing inner ring body is completed. Then start the extension end of the cylinder to extend. The extension end of the cylinder pushes the triangle plate to move. The movement of the triangle plate pushes the two grinding wheels to move. When the two grinding wheels are located on the inner and outer sides of the bearing inner ring body, the cylinder can be turned off. Then start the output end of the fourth motor to rotate. The output end of the fourth motor rotates the worm gear to rotate. The rotation of the worm gear drives the worm wheel to rotate. The rotation of the worm wheel drives the transmission gear and the third rotating rod to rotate. The rotation of the third rotating rod simultaneously drives the first crown gear and the second crown gear. When the crown gear rotates, the first crown gear and the second crown gear have opposite transmission directions. The rotation of the first crown gear and the second crown gear drives the two push plates to rotate. The rotation of the push plates pushes the slide rod to move. The movement of the slide rod pushes the outer rotating plate and the inner rotating plate to move. When the two push plates move towards one end at the same time, the two slide rods drive the outer rotating plate and the inner rotating plate to move towards one end at the same time. The other end of the outer rotating plate and the inner rotating plate drives the first rotating rod and the grinding wheel to move, so that the two grinding wheels are in contact with the inner and outer sides of the bearing inner ring body. When the two grinding wheels are in contact with the inner and outer sides of the bearing inner ring body, the fourth motor can be turned off. At this time, the output end of the third motor is started to rotate. The rotation of the output end of the third motor drives the drive gear to rotate. The rotation of the drive gear drives the two driven gears to rotate. The rotation of the driven gear drives the first rotating rod to rotate. The rotation of the first rotating rod drives the grinding wheel to rotate. At this time, the two grinding wheels can grind the inner and outer sides of the bearing inner ring body at the same time, which solves the problem that the traditional bearing inner ring body can only be ground on one side, and optimizes the grinding efficiency of the bearing inner ring body.

[0029] (2) In this scheme, the first support is for easy installation of the first motor, and the first motor is for easy rotation of the fixed frame. The rotation of the fixed frame drives the clamping mechanism to rotate, thereby causing the bearing inner ring body to rotate. The rotation of the bearing inner ring body, combined with the rotation of the two grinding wheels, facilitates simultaneous grinding of the inner and outer sides of the bearing inner ring body.

[0030] (3) In this scheme, the second support is for easy installation of the cylinder, and the cylinder is for easy movement of the triangular plate. The movement of the triangular plate drives the connecting rod to move, and the movement of the triangular plate drives the mounting plate and the outer shell to move, so as to drive the two grinding wheels to move into the inner ring body of the bearing.

[0048] Mounting plate 15 is located on the side of the bearing inner ring body 1. The right end of the mounting plate 15 is detachably connected to the outer shell 16. The mounting plate 15 has a first arc-shaped hole 17 and the outer shell 16 has a second arc-shaped hole 18.

[0049] Grinding wheel 25, two grinding wheels 25 are provided, and the two grinding wheels 25 slide in contact with the inner and outer sides of the bearing inner ring body 1 respectively.

[0050] In this embodiment, the first support 2 is for easy installation of the first motor 3, and the first motor 3 is for easy rotation of the fixing frame 4. The rotation of the fixing frame 4 drives the clamping mechanism to rotate, thereby causing the bearing inner ring body 1 to rotate. The rotation of the bearing inner ring body 1, in conjunction with the rotation of the two grinding wheels 25, facilitates simultaneous grinding of the inner and outer sides of the bearing inner ring body 1. The mounting plate 15 is for easy installation of the grinding mechanism, the outer shell 16 is for easy protection of the grinding mechanism, the opening of the first arc-shaped hole 17 is for easy sliding of the first rotating rod 24, and the opening of the second arc-shaped hole 18 is for easy sliding of the sliding rod 27. This invention solves the problem that traditional bearing inner ring body 1 can only be ground on one side when grinding by simultaneously grinding the inner and outer sides of the bearing inner ring body 1 with two grinding wheels 25, thus optimizing the efficiency of grinding the bearing inner ring body 1.

[0051] Specifically, the clamping mechanism includes a fixed frame 4, a mounting frame 5, a sliding hole 6, a bidirectional lead screw 7, a second motor 8, a nut 9, and a clamping plate 10.

The output end of the second motor 8 is started to rotate. The output end of the second motor 8 rotates and the bidirectional lead screw 7 rotates. The rotation of the bidirectional lead screw 7 drives the two nuts 9 to move on the surface of the bidirectional lead screw 7. When the bidirectional lead screw 7 rotates forward, the two nuts 9 move towards the end that is closer to each other. The movement of the nuts 9 drives the clamping plate 10 to move, so that the two clamping plates 10 clamp and fix the bearing inner ring body 1. The two clamping plates 10 fix the side of the bearing inner ring body 1. After the clamping plates 10 are fixed, the second motor 8 can be turned off. At this time, the fixing of the bearing inner ring body 1 is completed.

[0053] Specifically, the grinding mechanism includes a grinding component and an adjustment component, both of which are mounted on the mounting plate 15 and are connected to each other.

[0054] In this embodiment, the polishing mechanism includes a polishing component and an adjustment component, both of which are mounted on the mounting plate 15 and are connected to each other.

[0055] Specifically, the grinding assembly includes a third motor 19, a drive gear 20, a first rotating rod 24, and a driven gear 26.

[0056] In this embodiment, the output end of the third motor 19 is started to rotate. The rotation of the output end of the third motor 19 drives the drive gear 20 to rotate. The rotation of the drive gear 20 simultaneously drives the two driven gears 26 to rotate. The rotation of the driven gears 26 drives the first rotating rod 24 to rotate. And through the rotation of the first rotating rod 24, the grinding wheel 25 is driven to rotate. At this time, the two grinding wheels 25 can grind the inner and outer sides of the bearing inner ring body 1 at the same time, which solves the problem that the traditional bearing inner ring body 1 can only be ground on one side.

[0057] Specifically, the adjustment assembly includes a slide tube 21, an outer rotating plate 22, an inner rotating plate 23, and a slide rod 27. The slide tube 21 is fixedly connected to the right end of the drive gear 20. The outer rotating plate 22 and the inner rotating plate 23 are both sleeved on the surface of the slide tube 21, and the inner rotating plate 23 is located inside the outer rotating plate 22.

The two slide rods 27 are respectively fixedly connected to the other side ends of the outer rotating plate 22 and the inner rotating plate 23, and both slide rods 27 slide within the second arc-shaped hole 18.

[0058] In this embodiment, the slide tube 21 is for the convenience of fitting the outer rotating plate 22 and the inner rotating plate 23. The push plate 28 rotates to push the slide rod 27 to move. The movement of the slide rod 27 pushes the outer rotating plate 22 and the inner rotating plate 23 to move. When the two push plates 28 move towards one end at the same time, the two slide rods 27 drive the outer rotating plate 22 and the inner rotating plate 23 to move towards one end at the same time. The other end of the outer rotating plate 22 and the inner rotating plate 23 then drives the first rotating rod 24 and the grinding wheel 25 to move, so that the two grinding wheels 25 fit against the inner and outer sides of the bearing inner ring body 1.

[0059] Specifically, the actuation mechanism includes a drive component and a reversing drive component, both of which are mounted on the housing 16 and are connected to each other.

[0060] In this embodiment, the pushing mechanism includes a driving component and a reversing pushing component. Both the driving component and the reversing pushing component are disposed on the housing 16 and are connected to each other.

[0062] In this embodiment, the rotation of the third rotating rod 35 simultaneously drives the first crown gear 30 and the second crown gear 33 to rotate. At this time, the transmission directions of the first crown gear 30 and the second crown gear 33 are opposite. The rotation of the first crown gear 30 and the second crown gear 33 drives the two push plates 28 to rotate. The rotation of the push plates 28 pushes the slide rod 27 to move. The hollow rotating rod 29 is for fixing the first crown gear 30, and the second rotating rod 32 is for fixing the second crown gear 33. The transmission cooperation of the first crown gear 30, the second crown gear 33 and the transmission gear 36 makes the rotation directions of the two push plates 28 opposite, so as to push the slide rod 27 to move.

[0066] In this embodiment, the second support 11 is for the convenience of installing the cylinder 12, and the cylinder 12 is for the convenience of pushing the triangular plate 13 to move. The movement of the triangular plate 13 drives the connecting rod 14 to move, and the movement of the triangular plate 13 drives the mounting plate 15 and the outer shell 16 to move, so as to drive the two grinding wheels 25 to move into the bearing inner ring body 1.

[0069] Working principle: When using this device, first place the bearing inner ring body 1 between the two clamping plates 10. Then, start the output end of the second motor 8 to rotate. The rotation of the output end of the second motor 8 rotates the bidirectional lead screw 7. The rotation of the bidirectional lead screw 7 simultaneously drives the two nuts 9 to move on the surface of the bidirectional lead screw 7. When the bidirectional lead screw 7 rotates clockwise, the two nuts 9 move towards the closer end at the same time. The movement of the nuts 9 drives the clamping plates 10 to move, thereby clamping and fixing the bearing inner ring body 1 with the two clamping plates 10. The two clamping plates 10 also fix the side of the bearing inner ring body 1. After the clamping plates 10 are fixed, the second motor 8 can be turned off. At this time, the process is complete. After fixing the inner ring body 1 of the bearing, the extension end of the cylinder 12 is extended. The extension end of the cylinder 12 pushes the triangular plate 13 to move. The movement of the triangular plate 13 pushes the two grinding wheels 25 to move. When the two grinding wheels 25 are located on the inner and outer sides of the inner ring body 1 of the bearing, the cylinder 12 can be closed. Then, the output end of the fourth motor 39 is started to rotate. The rotation of the output end of the fourth motor 39 drives the worm 38 to rotate. The rotation of the worm 38 drives the worm wheel 31 to rotate. The rotation of the worm wheel 31 drives the transmission gear 36 and the third rotating rod 35 to rotate. The rotation of the third rotating rod 35 simultaneously drives the first crown gear 30 and the second crown gear 33 to rotate. When the first crown gear 30 and the second crown gear 33 rotate, their transmission directions are opposite. The rotation of the first crown gear 30 and the second crown gear 33 drives the two push plates 28 to rotate. The rotation of the push plates 28 pushes the slide rod 27 to move. The movement of the slide rod 27 pushes the outer rotating plate 22 and the inner rotating plate 23 to move. When the two push plates 28 move towards one end at the same time, the two slide rods 27 drive the outer rotating plate 22 and the inner rotating plate 23 to move towards one end at the same time. The other end of the outer rotating plate 22 and the inner rotating plate 23 drives the first rotating rod 24 and the grinding wheel 25 to move, so that the two grinding wheels 25 fit against the inner and outer sides of the bearing inner ring body 1. When the two grinding wheels 25 are in contact with the inner and outer sides of the bearing inner ring body 1, the fourth motor 39 can be turned off. At this time, the output end of the third motor 19 is started to rotate. The rotation of the output end of the third motor 19 drives the drive gear 20 to rotate. The rotation of the drive gear 20 drives the two driven gears 26 to rotate. The rotation of the driven gears 26 drives the first rotating rod 24 to rotate. And through the rotation of the first rotating rod 24, the grinding wheels 25 are driven to rotate. At this time, the two grinding wheels 25 can grind the inner and outer sides of the bearing inner ring body 1 at the same time, which solves the problem that the traditional bearing inner ring body 1 can only be ground on one side, and optimizes the efficiency of grinding the bearing inner ring body 1.
