Description
Technical Field
[0001] This utility model relates to the field of bearing processing technology, specifically to a bearing inner and outer ring synchronous grinding equipment. Background Technology
[0002] A bearing is a mechanical component whose main function is to support rotating shafts or other moving parts in mechanical equipment. At the same time, it can provide an interface between moving parts and stationary parts to reduce friction and improve motion efficiency and precision.
[0003] Currently, bearings are mainly composed of an inner ring, an outer ring, a roller body, a cage, and seals. To ensure the assembly accuracy of these components, the outer ring and the inner ring need to be ground using grinding equipment before assembly.
[0004] However, due to structural limitations, traditional grinding equipment cannot simultaneously grind both the outer and inner walls of the bearing ring, which greatly affects the grinding efficiency of the bearing.
[0005] Based on this, we propose a synchronous grinding equipment for bearing inner and outer rings to solve the above problems. Utility Model Content

[0044] like Figures 1-5 As shown, it illustrates a synchronous grinding device for the inner and outer rings of a bearing according to one embodiment of the present invention.
[0045] In some examples, including:
[0046] Platform 1, with an electromagnet 2 embedded in the middle of the top of platform 1, and hydraulic cylinders 3 fixedly connected to both ends of platform 1, and a support plate 4 fixedly connected between the output ends of the two hydraulic cylinders 3.
[0047] The transmission shaft 5 is vertically rotatably connected to the middle of the support plate 4. The bottom end of the transmission shaft 5 is fixedly connected to the mounting box 6, and both ends of the mounting box 6 are equipped with grinding components 7.
[0048] The power component 8 is mounted on the top of the support plate 4 and is used to drive the transmission shaft 5 to rotate.
[0049] For example, such as Figure 2 As shown, the grinding assembly 7 includes:
[0050] Support shaft 9 is slidably connected to the end of mounting box 6. The end of support shaft 9 away from mounting box 6 is fixedly connected to positioning frame 10. The bottom end of positioning frame 10 is rotatably connected to outer wall grinding roller 11.
[0051] The limiting slide rod 12 is vertically fixedly connected to the top of the positioning frame 10. The outer side of the limiting slide rod 12 is slidably connected to the displacement seat 13. The end of the displacement seat 13 away from the limiting slide rod 12 is fixedly connected to the bearing shaft rod 14. The outer side of the bearing shaft rod 14 is rotatably connected to the push rod 15.
[0052] The displacement frame 16 is slidably connected to the outside of the support shaft 9, and the end of the push rod 15 away from the bearing shaft 14 is rotatably connected to the top of the displacement frame 16. The bottom end of the displacement frame 16 is rotatably connected to the inner wall grinding roller 17.
[0053] An adjustment assembly is mounted between two bearing shafts 14 and is used to adjust the distance between the outer wall grinding roller 11 and the inner wall grinding roller 17 in conjunction with the displacement seat 13.
[0054] The linkage assembly is installed between the two support shafts 9 and is used to adjust the distance between the two outer wall grinding rollers 11 in conjunction with the support shafts 9.
[0055] For example, such as Figure 3 As shown, the top of the displacement frame 16 is fixedly connected to a mounting ear, and the end of the push rod 15 away from the bearing shaft 14 is connected to the mounting ear through a rotating shaft. By setting the mounting ear, the push rod 15 can be stably mounted between the bearing shaft 14 and the displacement frame 16 with the help of the rotating shaft, ensuring the application effect of the push rod 15.
[0056] For example, such as Figure 2 As shown, the power component 8 includes:
[0057] A transmission seat 18 is fixedly connected to the top of the support plate 4. A transmission motor 19 is fixedly connected to the top of the transmission seat 18. A transmission spur gear 20 is fixedly connected to the output end of the transmission motor 19. A reduction spur gear 21 is fixedly connected to the outer side of the support plate 4, and the reduction spur gear 21 meshes with the transmission spur gear 20.
[0058] For example, such as Figure 2 As shown, the adjustment components include:
[0059] Adjustment plate 22 is vertically slidably connected inside the transmission shaft 5. Both ends of adjustment plate 22 are fixedly connected to guide plate 23. Both ends of guide plate 23 are provided with guide slots 24, and the bearing shaft 14 is also movably connected inside the corresponding guide slots 24.
[0060] Electric push rod 25 is fixedly connected to the top of transmission base 18, and the output end of electric push rod 25 is rotatably connected to adjustment plate 22.
[0061] For example, such as Figure 2As shown, the transmission shaft 5 has a hollow structure. Both sides of the transmission shaft 5 are provided with clearance grooves that communicate with its inner cavity. The adjusting plate 22 extends through the clearance grooves to the outside of the transmission shaft 5. Due to the structural characteristics of the transmission shaft 5, the adjusting plate 22 can be set concentrically with the transmission shaft 5. With the setting of the clearance grooves, the adjusting plate 22 can be positioned from the outside of the transmission shaft 5. The existence of the clearance grooves can provide stable guidance for the vertical displacement of the adjusting plate 22.
[0062] In this embodiment, the top of the adjusting plate 22 is provided with an assembly hole, and the output end of the electric push rod 25 is connected to the inside of the assembly hole through a ball bearing. The connection between the adjusting plate 22 and the electric push rod 25 ensures that the presence of the electric push rod 25 will not affect the rotation of the transmission shaft 5. In addition, the ball bearing reduces wear between the adjusting plate 22 and the electric push rod 25.
[0063] For example, such as Figure 5 As shown, the linkage components include:
[0064] Linkage shaft 26 is vertically rotatably connected to the middle of the housing 6. Linkage spur gear 27 is fixedly connected to the outside of linkage shaft 26. Linkage rack 28 is fixedly connected to the two support shafts 9 at their close ends, and the two linkage racks 28 are respectively meshed with the two ends of linkage spur gear 27.
[0065] Extension seat 29 is fixedly connected to one end of the top of the mounting box 6. The top end of extension seat 29 is threadedly connected to a stabilizing screw 30. The bottom end of stabilizing screw 30 is fixedly connected to a locking rod 31, and the locking rod 31 is engaged with one of the support shaft rods 9.
[0066] For example, such as Figure 5 As shown, multiple locking holes are provided at the top of the support shaft 9 near the locking rod 31, and the locking rod 31 is engaged with the inside of the locking holes. By setting the locking holes, when the locking rod 31 moves towards the support shaft 9, it can move into the locking holes, thereby forming an effective lock on the support shaft 9 and preventing the support shaft 9 from sliding uncontrollably.
[0067] More specifically, a stabilizing block is threaded to the bottom of the outer side of the stabilizing screw 30. The top of the stabilizing block has anti-slip grooves. By setting the stabilizing block, after the stabilizing screw 30 is driven, rotating the stabilizing block will cause the stabilizing block to move towards the extension seat 29. When the stabilizing block and the extension seat 29 are tightly attached, the friction of the rotation of the stabilizing screw 30 can be increased, thereby preventing the stabilizing screw 30 from rotating uncontrollably.
[0068] Working principle: First, the outer ring of the bearing is placed at the electromagnet 2, and the electromagnet 2 is activated to attract the outer ring onto the electromagnet 2, thereby achieving the positioning of the outer ring. Then, the hydraulic cylinder 3 is activated to pull the support plate 4 downward until the outer wall grinding roller 11 and the inner wall grinding roller 17 contact the outer wall and inner wall of the outer ring, respectively. Then, the drive motor 19 is activated to cause the drive spur gear 20 to drive the reduction spur gear 21, which in turn drives the outer wall grinding roller 11 and the inner wall grinding roller 17 to revolve along the drive shaft 5 through the drive shaft 5 and the mounting box 6. In this way, by means of the contact between the outer wall grinding roller 11 and the inner wall grinding roller 17 and the outer ring of the bearing, the outer wall and inner wall of the outer ring are ground synchronously, which greatly improves the grinding efficiency of the outer ring.
[0069] Furthermore, the electric push rod 25 can be activated to push the adjusting plate 22 to move vertically under the support of the transmission shaft 5, changing the vertical position of the guide plate 23. In conjunction with the connection between the guide slot 24 and the bearing shaft 14, when the guide slot 24 is adjusted vertically, it can press the bearing shaft 14, causing the displacement seat 13 to move vertically under the guidance of the limiting slide rod 12. Since the push rod 15 is connected between the bearing shaft 14 and the displacement frame 16, when the limiting slide rod 12 moves, it can push the push rod 15 to move along the support shaft 9, thereby changing the distance between the outer wall grinding roller 11 and the inner wall grinding roller 17 to adapt to outer rings of different thicknesses.
[0070] Furthermore, the rotatable stabilizing screw 30, connected to the extension seat 29, allows the stabilizing screw 30 to move vertically along the extension seat 29. When the locking rod 31 disengages from the support shaft 9, the support shaft 9 can be unlocked. Then, the support shaft 9 is pulled, causing it to move under the support of the mounting box 6. The linkage rack 28 at the displacement support shaft 9 actuates the linkage spur gear 27. Since the linkage spur gear 27 is located between the two linkage racks 28, it can actuate the other linkage rack 28, causing the two support shafts 9 to move towards each other, changing the distance between the two inner wall grinding rollers 17, thus adapting to bearing outer rings of different specifications.
[0071] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
