Description

Technical Field

[0001] This utility model belongs to the field of bearing outer ring processing technology, and in particular relates to a bearing inner and outer ring grinding 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. Bearings generally consist of an inner and outer ring. During the manufacturing process, the inner and outer surfaces of the bearing outer ring inevitably have some burrs. These burrs can have adverse effects on later use and installation.

[0003] In the prior art, a mechanism for grinding the inner and outer rings of a bearing, patent number CN211332477U, includes an inner ring grinding block. A first rotating cylinder is hinged inside the inner ring grinding block. Two opposing inner ring abutments that can approach or move away from the center line of the first rotating cylinder are movably connected to the first rotating cylinder. An outer ring grinding module is movably connected to one side of the inner ring grinding block, which can approach or move away from the inner ring grinding block in a horizontal direction. Two outer ring abutments that correspond one-to-one with the inner ring abutments are movably connected to the outer ring grinding module. The inner ring grinding block is also provided with a base, and a drive component for grinding the bearing is provided inside the base.

[0004] In the aforementioned device, the outer surface of the bearing ring is clamped by two outer ring abutments, and the inner surface of the bearing outer ring is clamped by two inner ring abutments. Then, the inner and outer surfaces of the bearing outer ring are polished. However, during the polishing process, the fixed state of the bearing outer ring will become unstable due to the rotation of the outer ring abutments and inner ring abutments, which will affect the polishing effect. Furthermore, the polishing method in the aforementioned device will generate a large amount of flying debris, which will affect the working environment. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, which is that the fixed state of the bearing outer ring is unstable due to the rotation of the outer ring abutment plate and the inner ring abutment plate during the grinding process, this utility model provides a bearing inner and outer ring grinding device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing inner and outer ring grinding device, comprising a base plate and a protective frame, wherein a first rotating seat and a second rotating seat are symmetrically arranged on the surface of the base plate, the first rotating seat is fixed to the upper surface of the base plate, and the second rotating seat is slidably disposed on the upper surface of the base plate.

[0007] A feeding frame communicating with the protective frame is fixedly installed at the lower end of the protective frame. A support block is fixedly connected between the feeding frame and the base plate. A collection frame is slidably installed inside the feeding frame. The collection frame can be pulled away from the feeding frame.

[0008] The rotating output ends of both rotating seat one and rotating seat two are fixedly equipped with rotating plates, and the outer surfaces of the rotating plates of rotating seat one and rotating seat two are respectively arranged in a ring shape with a plurality of clamping cylinders one and clamping cylinder two.

[0009] Optionally, a support plate is fixedly provided on the upper surface of the base plate, and a lead screw is rotatably provided between the support plate and the rotating seat one fixedly installed on the base plate. The lead screw passes through the base plate position of the rotating seat two and is threaded.

[0010] Optionally, a clamping block is fixedly installed on the outer end of the piston rod of the clamping cylinder one, and a stop is fixedly provided on the inner surface of the clamping block one. A clamping block two is fixedly installed on the outer end of the piston rod of the clamping cylinder two, and the outer surface of the clamping block two is arc-shaped.

[0011] Optionally, a grinding cylinder two, perpendicular to the ground, is fixedly installed on the outer surface of the rotating plate on the rotating seat two at a position away from the clamping cylinder two.

[0012] Optionally, a connecting exhaust pipe is fixedly installed on the outer side of the feeding frame, and the collection frame is set in a trapezoidal shape.

[0013] Optionally, a support block two is fixedly installed on the upper inner wall of the protective frame, and a grinding cylinder one is fixedly installed on the lower surface of the support block two. A connecting block is fixedly installed at the lower end of the piston rod of both the grinding cylinder one and the grinding cylinder two, and grinding component one and grinding component two are respectively installed in the two connecting blocks.

[0015] Optionally, the outer surface of the rotating plate is provided with an annular groove, which is rotatably engaged with both ends of the protective frame.

[0016] In summary, compared with the prior art, the bearing grinding device for inner and outer rings provided by this utility model has the following advantages:

[0017] 1. In this utility model, when the inner surface of the bearing outer ring is being polished, the outer surface is first fixed by the clamping cylinder, and then the rotating seat is brought close to the bearing outer ring. At this time, the clamping block 2 and the polishing part 2 are brought together and enter the bearing outer ring. After that, the polishing cylinder 2 retracts, so that the polishing part 2 is tightly attached to the inner surface of the bearing outer ring. Then, the rotating seat 1 is started to drive the bearing outer ring to rotate. At this time, the polishing part 2 polishes the inner surface of the bearing outer ring. This method can effectively ensure that the bearing outer ring will not shake when polishing the inner surface of the bearing outer ring, and effectively improve the polishing effect of the bearing outer ring.

[0018] 2. In this utility model, when grinding the outer surface of the bearing outer ring, the grinding cylinder two is reset, and then the clamping cylinder two begins to clamp the inner ring of the bearing. Then, the clamping cylinder one releases the clamp on the bearing outer ring and resets. At this time, the grinding cylinder one drives the grinding component one to contact the outer surface of the bearing outer ring, and then the rotating seat two is started to drive the bearing outer ring to rotate. At this time, the grinding component one grinds the outer surface of the bearing outer ring. This method can effectively fix and clamp the bearing outer ring, ensuring the stability of the bearing outer ring during the grinding process.

[0019] 3. In this utility model, during the grinding process, an external exhaust fan draws the grinding debris from the protective frame into a collection frame for collection. At this time, the protective frame can effectively block the grinding debris and prevent it from splashing. Attached Figure Description

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] refer to Figure 1-3A bearing grinding device for inner and outer rings includes a base plate 1 and symmetrically arranged rotating seats 2 and 21. The rotating seats are prior art and need not be drawn and described in detail here. The rotating seat 2 is fixed to the upper surface of the base plate 1 by bolts, and the rotating seat 21 is slidably disposed on the upper surface of the base plate 1. Both the rotating seat 2 and the rotating seat 21 are equipped with components for clamping the outer ring of the bearing.

[0028] refer to Figure 1-3 A support plate 11 is fixedly installed on the upper surface of the base plate 1. A lead screw 3 is rotatably installed on one side between the support plate 11 and the rotating seat 2 fixedly installed on the base plate 1, and a limit shaft 31 is fixedly connected on the other side. The lead screw 3 passes through the position of the rotating seat 21 on the base plate 1 and is threaded. The limit shaft 31 passes through the position of the rotating seat 21 on the base plate 1 and is slidably connected. A motor 111 is fixedly installed on the outer side of the support plate 11. The motor 111 drives the lead screw 3 to rotate, thereby driving the rotating seat 21 to slide on the surface of the base plate 1.

[0029] refer to Figure 1-3 Both the rotating output ends of rotating seat 1 2 and rotating seat 2 21 are fixedly equipped with circular rotating plates 5. The outer surfaces of the rotating plates 5 of rotating seat 1 2 and rotating seat 2 21 are respectively arranged in a ring with several clamping cylinders 1 7 and clamping cylinders 2 6. Clamping cylinders 1 7 are used to clamp and fix the outer surface of the bearing outer ring, and clamping cylinders 2 6 are used to clamp and fix the inner surface of the bearing outer ring.

[0030] refer to Figure 2-5 A clamping block 71 is fixedly installed at the outer end of the piston rod of the clamping cylinder 7. A stop block 711 is fixedly provided on the inner surface of the clamping block 71. The stop block 711 is used to limit the outer ring of the bearing and will not obstruct the grinding process of the inner surface of the outer ring of the bearing.

[0031] refer to Figure 2-5 A clamping block 2 62 is fixedly installed at the outer end of the piston rod of the clamping cylinder 2 6. The outer surface of the clamping block 2 62 is arc-shaped, and it can clamp and fix the inner surface of the bearing outer ring by driving the clamping cylinder 2 6.

[0032] refer to Figure 2-5 A grinding cylinder 261, perpendicular to the ground, is fixedly installed on the outer surface of the rotating plate 5 on the rotating seat 21 at a position away from the clamping cylinder 26. A grinding part 2611, which is specially used to grind the inner surface of the outer ring of the bearing, is installed below the grinding cylinder 261.

[0033] Specifically, the outer surface of the bearing outer ring is first fixed by the clamping cylinder 7, and then the rotation of the lead screw 3 is driven by the motor 111, so that the rotating seat 21 approaches the bearing outer ring. At this time, the clamping block 22 and the grinding part 21 come together and enter the bearing outer ring. After entering the bearing outer ring, the grinding cylinder 261 retracts, so that the grinding part 2611 is tightly attached to the inner surface of the bearing outer ring. Then the rotating seat 2 is started to drive the bearing outer ring to rotate. At this time, the grinding part 2611 grinds the inner surface of the bearing outer ring.

[0034] refer to Figure 2-5 In this embodiment, in order to effectively grind the outer surface of the bearing outer ring and to collect the grinding debris during the grinding process, a protective frame 4 can be set between the rotating seat 1 2 and the rotating seat 2 21. A feeding frame 42 communicating with the protective frame 4 is fixedly set at the lower end of the protective frame 4. A collection frame 43 is slidably set in the feeding frame 42. The collection frame 43 can be pulled away from the feeding frame 42, and then the grinding debris in the collection frame 43 can be taken out.

[0035] refer to Figure 2-5 A connecting exhaust pipe 421 is fixedly installed on the outer side of the feeding frame 42. The exhaust pipe 421 is used to connect to an external exhaust fan. The exhaust fan is existing technology and does not need to be drawn and described in detail here. The collection frame 43 is set as a trapezoid, and the inclined part of the collection frame 43 is divided into a filter plate, which can improve the exhaust effect of the exhaust fan on the protective frame 4, so that the grinding debris can enter the collection frame 43 better.

[0036] refer to Figure 2-5 A support block 12 is fixedly connected between the feeding frame 42 and the base plate 1 to fix the protective frame 4.

[0037] refer to Figure 2-5 A ventilation hole 414 communicating with the interior is symmetrically provided on the upper surface of the protective frame 4. The ventilation hole 414 is designed to ensure that the air pressure inside the protective frame 4 is stable when the air is being ventilated.

[0038] refer to Figure 2-5 The outer surface of the rotating plate 5 is provided with an annular groove 51. The annular groove 51 is rotated with both ends of the protective frame 4. When the rotating seat 1 2 and the rotating seat 2 21 drive the rotating plate 5 to rotate, they will not affect the protective frame 4. At this time, the protective frame 4 can effectively block the grinding debris and prevent the grinding debris from splashing. The rotating plate 5 on the rotating seat 1 2 is in contact with the protective frame 4 for a long time.

[0039] refer to Figure 2-5A support block 2 411 is fixedly installed on the upper inner wall of the protective frame 4. A grinding cylinder 1 41 is fixedly installed on the lower surface of the support block 2 411. A connecting block 412 is fixedly installed at the lower end of the piston rod of the grinding cylinder 1 41. A grinding part 1 413 is installed inside the connecting block 412. The connecting block 412 and the grinding part 1 413 are fastened by bolts, so that the grinding part 1 413 can be replaced when grinding the outer ring of bearings of different sizes.

[0040] refer to Figure 2-5 The grinding cylinder 41 and the grinding cylinder 61 are connected to the grinding component in the same way. The grinding cylinder 61 is also connected to the grinding component 611 through the connecting block 412. The grinding component 611 can be replaced for bearing outer rings of different sizes.

[0041] Specifically, the grinding cylinder 41 is located to the right of the clamping cylinder 7, and is not on the same vertical plane as the clamping cylinder 7.

[0042] Furthermore, after the inner surface of the bearing outer ring is polished, polishing cylinder 2 61 is reset, and then clamping cylinder 2 6 begins to clamp the inner ring of the bearing. Then clamping cylinder 1 7 releases the clamp on the bearing outer ring and resets. At this time, polishing cylinder 1 41 drives polishing component 1 413 to contact the outer surface of the bearing outer ring, and then the rotating seat 21 is started to drive the bearing outer ring to rotate. At this time, polishing component 1 413 polishes the outer surface of the bearing outer ring. During the polishing process, an external exhaust fan is used to extract the polishing debris in the protective frame 4 into the collection frame 43 for collection.
