Description

Technical Field

[0001] This utility model relates to the field of bearing roller grinding technology, and in particular to a bearing roller grinding machine. Background Technology

[0002] Bearing rollers are key components of rolling bearings, and come in various types, including cylindrical, tapered, and spherical. They are commonly made of bearing steel or ceramic, each suitable for different operating conditions. They bear loads, distributing them evenly across the raceway, thus improving bearing capacity and lifespan; they also reduce friction, minimizing energy loss and heat generation, ensuring stable equipment operation. The machining of bearing rollers is crucial to bearing performance. Grinding machines can improve dimensional accuracy, controlling diameter and length within extremely small tolerances to meet high-precision application requirements; improve surface quality, reduce friction, and enhance fatigue resistance; ensure shape accuracy and avoid localized stress concentration; and can also be used to machine ceramic rollers from different materials, such as using diamond grinding discs, to meet diverse processing needs.

[0003] Some existing bearing roller grinding machines rely primarily on relatively fixed mechanical structures during the grinding operation. For example, they employ an integrated grinding mold, a fixed grinding space, and relatively simple mechanical transmission, such as a single motor driving a grinding disc to rotate at a constant speed, to grind bearing rollers placed in a specific position. This technical principle focuses on maintaining a stable grinding motion, but it has certain limitations in adapting to rollers of different specifications.

[0004] However, these traditional grinding machines have significant drawbacks. Because they cannot adjust the slit size, they can only process bearing rollers within a specific size range. In actual production, companies often need to produce bearings of various specifications to meet the needs of different customers and markets. However, limited by the fixed slit size of existing grinding machines, whenever a new size of roller needs to be processed, the entire grinding equipment must be replaced or a complex and time-consuming modification must be made. This greatly reduces production efficiency, increases production costs, and severely restricts the diversity and flexibility of enterprise production, making it difficult to meet the market's demand for rapid response to diverse bearing products. Therefore, a bearing roller grinding machine is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bearing roller grinding machine, which aims to improve the problem that the existing technology cannot adjust the gap and can only process bearing rollers within a specific size range.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bearing roller grinding machine includes a protective shell, a brushless motor fixedly connected to the side wall of the protective shell, a screw fixedly connected to the output end of the brushless motor, a movable plate threadedly connected to the outer wall of the screw, a first fixed plate fixedly connected to the top of the movable plate, a second fixed plate fixedly connected to the top of the first fixed plate, and an adjustment component provided on the inner wall of the protective shell.

[0008] The adjustment assembly includes a third fixing plate, the side wall of which is fixedly connected to the inner wall of the protective shell, a base plate fixedly connected to the top of the third fixing plate, a double-headed hydraulic cylinder fixedly connected to the top of the base plate, a sliding block fixedly connected to the output end of the double-headed hydraulic cylinder, a first bevel gear rotatably connected to the side wall of the sliding block, a second bevel gear rotatably connected to the side wall of the sliding block, a rotating column fixedly connected to one end of the second bevel gear, the first bevel gear meshing with the second bevel gear, and a support assembly provided at the bottom of the third fixing plate.

[0010] The support assembly includes a first support plate, the top of which is fixedly connected to the bottom of a third fixed plate, and a second support plate is fixedly connected to the side wall of the first support plate.

[0011] As a further description of the above technical solution:

[0012] The top of the second support plate is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a first synchronous pulley, the top of the third fixed plate is rotatably connected to a linkage column, the outer wall of the linkage column is fixedly connected to a second synchronous pulley, and the outer wall of the second synchronous pulley and the first synchronous pulley are rotatably connected to a chain;

[0013] As a further description of the above technical solution:

[0014] A hollow plate is fixedly connected inside the protective shell, a conveying pipe is provided inside the hollow plate, and a water tank is fixedly connected to the side wall of the protective shell.

[0015] As a further description of the above technical solution:

[0016] One end of the conveying pipe is set inside the water tank, and a hollow column is fixedly connected to one end of the conveying pipe. A first rotating ring is rotatably connected to the inner wall of the hollow column.

[0017] As a further description of the above technical solution:

[0018] A wrench is fixedly connected to the outer wall of the first rotating ring, and the outer wall of the wrench is slidably connected to the inside of the hollow column. A linkage rod is rotatably connected to the side wall of the first rotating ring.

[0019] As a further description of the above technical solution:

[0020] The linkage rod is rotatably connected to a soft-pack fan blade, and the soft-pack fan blade is rotatably connected to a second rotating ring.

[0021] As a further description of the above technical solution:

[0022] The second rotating ring sidewall is rotatably connected to the inner wall of the hollow column, the first rotating ring sidewall is rotatably connected to the inner wall of the hollow column, and a nozzle is fixedly connected to the sidewall of the hollow column.

[0023] This utility model has the following beneficial effects:

[0024] In this invention, a sliding block is driven to move by a double-headed hydraulic cylinder. The movement of the sliding block drives both the first and second bevel gears to move to the top of the base plate. Then, the movement of the sliding block drives the rotating column on the side wall to move, thereby achieving the effect of adjusting the gap of the rotating column. This solves the problem that the bearing rollers can only be processed within a specific size range because the gap cannot be adjusted, and improves the versatility of the bearing roller grinding machine.

[0025] In this invention, by pulling a wrench, the wrench is forced to rotate the linkage rod, which in turn rotates the soft-pack fan blades on the side wall, thus achieving the effect of flow rate regulation. This solves the problem that the inability to adjust the coolant flow rate leads to different requirements for coolant flow rate due to different grinding processes, roller materials, and grinding speeds, thereby improving the applicability of the bearing roller grinding machine.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a bearing roller grinding machine, including a protective shell 1. The protective shell 1 is made of high-strength steel, which has good structural strength and wear resistance, and can effectively protect the internal components from external impact and damage. A brushless motor 2 is fixedly connected to the side wall of the protective shell 1. A screw 3 is fixedly connected to the output end of the brushless motor 2. The screw 3 is made of high-strength stainless steel, which has good mechanical strength and corrosion resistance. A movable plate 4 is threadedly connected to the outer wall of the screw 3. A first fixed plate 5 is fixedly connected to the top of the movable plate 4. A second fixed plate 6 is fixedly connected to the top of the first fixed plate 5. Both the first fixed plate 5 and the second fixed plate 6 are made of high-strength plastic, which has good wear resistance and stability. An adjustment component is provided on the inner wall of the protective shell 1.

[0034] The adjustment assembly includes a third fixed plate 7, the side wall of which is fixedly connected to the inner wall of the protective shell 1. A base plate 30 is fixedly connected to the top of the third fixed plate 7. A double-headed hydraulic cylinder 22 is fixedly connected to the top of the base plate 30. A sliding block 20 is fixedly connected to the output end of the double-headed hydraulic cylinder 22. The sliding block 20 is made of high-strength aluminum alloy, which has good mechanical strength and wear resistance. A first bevel gear 18 is rotatably connected to the side wall of the sliding block 20. A second bevel gear 19 is rotatably connected to the side wall of the sliding block 20. A rotating column 21 is fixedly connected to one end of the second bevel gear 19. The rotating column 21 is made of high-strength stainless steel, which has good mechanical strength and corrosion resistance. The first bevel gear 18 and the second bevel gear 19 mesh with each other. Both the first bevel gear 18 and the second bevel gear 19 are made of high-strength steel, which has good wear resistance and transmission efficiency. A support assembly is provided at the bottom of the third fixed plate 7.

[0035] Specifically, when using a bearing roller grinding machine for roller grinding, the roller to be ground is first placed on the outer wall of the rotating column 21. Then, the double-headed hydraulic cylinder 22 is activated, and its output end pushes the sliding block 20 along a predetermined trajectory. The movement of the sliding block 20 causes the first bevel gear 18 on its side wall to move as well. Since the first bevel gear 18 and the second bevel gear 19 mesh with each other, the movement of the sliding block 20 simultaneously drives the second bevel gear 19 to move. The movement of the second bevel gear 19 further affects the rotating column 21 on its side wall, causing it to move accordingly. This adjusts the gap between the rotating columns 21 to accommodate the grinding requirements of rollers of different sizes, ensuring the uniformity and precision of the grinding process, thereby improving the processing quality and production efficiency of the rollers.

[0036] Reference Figure 1 , Figure 3 and Figure 4A perforated plate 8 is fixedly connected inside the protective shell 1. A delivery pipe 9 is installed inside the perforated plate 8. The delivery pipe 9 is made of corrosion-resistant PVC material to ensure smooth coolant delivery. A water tank 10 is fixedly connected to the side wall of the protective shell 1. The water tank 10 is made of stainless steel, providing good corrosion resistance and sealing, and can store coolant. One end of the delivery pipe 9 is located inside the water tank 10, and a hollow column 24 is fixedly connected to the other end of the delivery pipe 9. The hollow column 24 is made of high-strength plastic, providing good mechanical strength and wear resistance. A first rotating ring 26 is rotatably connected to the inner wall of the hollow column 24, and the outer wall of the first rotating ring 26 is fixed... A wrench 25 is connected, and the outer wall of the wrench 25 is slidably connected to the inside of the hollow column 24. A linkage rod 29 is rotatably connected to the side wall of the first rotating ring 26, and a soft-pack fan blade 28 is rotatably connected to the side wall of the linkage rod 29. The soft-pack fan blade 28 is made of flexible rubber and has good sealing and adjustment performance. A second rotating ring 27 is rotatably connected to the side wall of the soft-pack fan blade 28 and is rotatably connected to the inner wall of the hollow column 24. The side wall of the first rotating ring 26 is rotatably connected to the inner wall of the hollow column 24. A nozzle 23 is fixedly connected to the side wall of the hollow column 24. The nozzle 23 is made of stainless steel and has good corrosion resistance and spraying performance.

[0037] Specifically, during the adjustment of the coolant flow rate, the operator first pulls the wrench 25. When force is applied to the wrench 25, it causes the first rotating ring 26 connected to it to rotate. The rotation of the first rotating ring 26, through a linkage mechanism, drives the linkage rod 29 to rotate as well. The rotation of the linkage rod 29 further affects the flexible fan blades 28 on its side wall, causing them to rotate. During rotation, the flexible fan blades 28 adjust within the second rotating ring 27. By changing the position and angle of the flexible fan blades 28, the coolant flow rate can be effectively controlled, thereby achieving precise adjustment of the cooling process. This makes the adjustment of the coolant flow rate more flexible and convenient, helping to improve the operating efficiency and cooling effect of the equipment.

[0038] Reference Figure 2The support assembly includes a first support plate 11, which is made of high-strength steel and has good mechanical strength and stability. The top of the first support plate 11 is fixedly connected to the bottom of the third fixed plate 7. A second support plate 12 is fixedly connected to the side wall of the first support plate 11. The second support plate 12 is also made of high-strength steel and has good mechanical strength and stability. A first motor 13 is fixedly connected to the top of the second support plate 12. A first synchronous pulley 14 is fixedly connected to the output end of the first motor 13. The first synchronous pulley 14 is made of high-strength plastic and has good wear resistance and transmission efficiency. A linkage column 17 is rotatably connected to the top of the third fixed plate 7. A second synchronous pulley 16 is fixedly connected to the outer wall of the linkage column 17. A chain 15 is rotatably connected to the outer wall of the second synchronous pulley 16 and the first synchronous pulley 14. The chain 15 is made of high-strength steel to ensure the stability and durability of the transmission.

[0039] Specifically, during the operation of the bearing roller grinding machine, after the first motor 13 starts, its output end drives the first synchronous pulley 14 to rotate. The rotation of the first synchronous pulley 14 transmits power to the chain 15 through the transmission action, causing it to rotate synchronously. During the rotation of the chain 15, it drives the second synchronous pulley 16 connected to it to rotate as well. The rotation of the second synchronous pulley 16 further drives the linkage column 17 on its side wall to rotate. The rotation of the linkage column 17 drives the first bevel gear 18 on its outer wall to rotate. Since the first bevel gear 18 and the second bevel gear 19 mesh with each other, the rotation of the first bevel gear 18 drives the second bevel gear 19 to rotate synchronously. Finally, the rotation of the second bevel gear 19 drives the rotating column 21 on its side wall to rotate, achieving precise driving of the rotating column 21, ensuring the continuity and stability of the roller grinding process, and improving grinding efficiency and processing accuracy.

[0040] Working principle: When using the bearing roller grinding machine, the roller to be ground is first placed on the outer wall of the rotating column 21. Then, the output end of the double-headed hydraulic cylinder 22 drives the sliding block 20 to move. The movement of the sliding block 20 drives the first bevel gear 18 on the side wall to move. Then, during the movement of the sliding block 20, the second bevel gear 19 is also driven to move. Then, the movement of the second bevel gear 19 drives the rotating column 21 on the side wall to move, thus achieving the effect of adjusting the gap of the rotating column 21.

[0041] Subsequently, the output of the first motor 13 drives the first synchronous wheel 14 to rotate. The rotation of the first synchronous wheel 14 also drives the chain 15 on the outer wall to rotate. Then, as the chain 15 rotates, it also drives the second synchronous wheel 16 to rotate. As the second synchronous wheel 16 rotates, it drives the linkage column 17 to rotate. The rotation of the linkage column 17 drives the first bevel gear 18 on the outer wall to rotate. The rotation of the first bevel gear 18 drives the second bevel gear 19, which meshes with it, to rotate. The rotation of the second bevel gear 19 also drives the rotating column 21 on the side wall to rotate, thus achieving the effect of driving the rotating column 21 to rotate.

[0042] Subsequently, when adjusting the coolant flow rate, firstly, wrench 25 is pulled. The force applied to wrench 25 causes the first rotating ring 26 to rotate. Then, the rotation of the first rotating ring 26 causes the linkage rod 29 to rotate. During the rotation of the linkage rod 29, the soft-pack fan blade 28 on the side wall will rotate. Then, during the rotation of the soft-pack fan blade 28, it will rotate inside the second rotating ring 27, thus achieving the effect of controlling the coolant flow rate.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
