[0002] In modern industrial production, bearings are key components in many mechanical equipment and are widely used in many fields such as automobiles, aerospace, and machinery manufacturing. In order to meet the market demand for bearings, manufacturers need to process large quantities of bearings efficiently and with high precision in a short period of time. In particular, the processing of the outer ring raceway of the bearing has a direct impact on its geometric accuracy and surface quality, which directly affects the performance and life of the bearing.

[0003] In the traditional bearing outer ring raceway processing, the bearing outer ring is usually made of high-hardness steel, which causes greater wear on the tool during processing. High-speed and high-pressure processing conditions will accelerate the wear of the tool. If the coolant supply is insufficient or the lubrication effect is poor, it will also cause the tool to overheat and wear quickly. When the tool wear reaches a certain level, the machine must be stopped to replace the new tool.

DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0021] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0023] Reference Figure 1 to Figure 9 An automatic bearing outer ring raceway grinder is proposed, comprising: a column 1, which is rotatably arranged and has a side wall with a vertically arranged first slide groove 101, and the first slide groove 101 has at least two; a first set 2, which has two first sets 2, both of which are rotatably sleeved on the column 1, and the first set 2 has an arcuate edge 201, and the arcuate edges 201 of the two first sets 2 are adjacent and arranged at intervals, and a second slide groove 202 is formed between the two first sets 2, and the second slide groove 202 is connected to the first slide groove 101; a grinding piece 3, which has a first sliding part 301 and a second sliding part 302, the first sliding part 301 is slidably arranged in the first slide groove 101, and the second sliding part 302 is slidably arranged in the second slide groove 202, and after the column 1 rotates, it drives the grinding piece 3 to follow the rotation in the horizontal direction and rise and fall in the height direction.

[0024] The liquid spraying member 6 is used for spraying cooling liquid. The spraying port of the liquid spraying member 6 faces the grinding station 401 and is located below the storage box 5 in the height direction.

[0025] In this embodiment, in the design of the grinding device, the column 1 is used as a core component, which not only provides structural support, but also realizes the position adjustment of the grinding piece 3 through its rotation setting. There are at least two first slide grooves 101 arranged vertically on the side wall of the column 1, which provides a basis for the installation of the grinding piece 3. There are two first sets 2, both of which are sleeved on the column 1, and each has an arc edge 201. When the two first sets 2 are arranged adjacent to each other, the gap between the two arc edges 201 forms a second slide groove 202, and the second slide groove 202 is connected to the first slide groove 101 on the column 1. Such a structure enables the grinding piece 3 to be positioned through the first slide groove 101 and the second slide groove 202 at the same time, ensuring the stability and accuracy of the grinding piece 3 during movement. The grinding piece 3 itself includes two parts: a first sliding part 301 and a second sliding part 302. The first sliding part 301 is located in the first slide groove 101 of the column 1, and the second sliding part 302 is placed in the second slide groove 202 formed by the first set 2. This dual-track layout ensures that the grinding piece 3 can maintain good guiding performance even in complex working environments. In addition, the first slide 101 in the form of a dovetail groove further enhances the safety and stability of the grinding piece 3 when it moves up and down along the column 1. The liquid spraying element 6 is responsible for spraying coolant into the working area to help reduce the processing temperature, extend the tool life, and improve the surface quality of the workpiece. It is located below the storage box 5 but above the main working area, which not only ensures effective cooling but also avoids unnecessary contamination of the non-operating grinding piece 3. A key advantage of the entire system is that it can quickly replace worn grinding pieces 3 without long downtime. When the performance of a grinding piece 3 deteriorates due to long-term use, a better grinding piece 3 can be replaced by simply rotating the column 1. In this process, in addition to the horizontal displacement, there will also be a change in vertical height - this is to take into account the needs of the actual operating environment, such as preventing contaminants such as coolant and chips from contacting the spare or newly replaced grinding piece 3, and also making it easier for maintenance personnel to approach these components from above for inspection or replacement, thereby greatly improving work efficiency and safety.

[0026] Furthermore, the machine tool 4 has two grinding stations 401; the storage box 5 is arranged on the machine tool 4 and is located at the upper part of the column 1. The storage box 5 has a storage space 501, and the storage space 501 has two openings 502. After the grinding piece 3 moves, it enters the storage space 501 through one opening 502 or moves out of the storage space 501 through the other opening 502; the column 1 has four first slide grooves 101, and each first slide groove 101 is correspondingly provided with a grinding piece 3. After the column 1 rotates, two of the grinding pieces 3 are respectively located at the two grinding stations 401, and the other two grinding pieces 3 are respectively located in the two storage spaces 501.

[0027] In this embodiment, the machine tool 4 is specially designed with two grinding stations 401, which allows two sets of bearing outer rings to be processed at the same time, greatly improving production efficiency. A storage box 5 is set above the machine tool 4, located on the upper part of the column 1, mainly used to store unused or replaced grinding parts 3. A special storage space 501 is set inside the storage box 5, and the storage space 501 is connected to the lower outside through two through-ports 502. When the grinding part 3 completes the work or reaches the predetermined degree of wear, it can be sent to the storage space 501 through a through-port 502; and the new and intact grinding part 3 can be removed from the storage space 501 through another through-port 502, ready to participate in the next processing cycle.

[0028] Four first chutes 101 are evenly distributed on the column 1. Each first chute 101 can independently accommodate a grinding piece 3. This configuration enables the column 1 to control the position conversion of the four grinding pieces 3 when rotating. When the column 1 rotates to a specific angle, two of the grinding pieces 3 will be exactly in the working area of ​​the machine tool 4 (i.e., two grinding stations 401) and start to perform the grinding task; at the same time, the other two grinding pieces 3 will automatically move to the designated position in the storage box 5 and wait. This mechanism not only realizes a fast and efficient replacement process of the grinding pieces 3, but also ensures the continuous and uninterrupted processing process, greatly reducing non-productive downtime.

[0029] In the initial state, two intact spare grinding parts 3 are stored in the storage box 5. When the working grinding part 3 shows obvious signs of wear, the operator only needs to drive the cylinder 1 to rotate through the system or other means to achieve the exchange between the new and old grinding parts 3. The new grinding part 3 then enters the grinding station 401 to continue working, and the replaced grinding part 3 is sent to the storage box 5 to wait for subsequent processing or maintenance. The existence of the storage box 5 provides a safe, clean and easily accessible storage environment for unused grinding parts 3, especially considering its height advantage relative to the actual processing area, further reducing the risk of contaminant intrusion. Through the application of the above-mentioned design scheme, the present invention successfully overcomes the various disadvantages brought about by frequent shutdowns for tool replacement in traditional methods, not only significantly improving the output within a single processing cycle, but also optimizing the overall operational convenience and safety, laying a solid foundation for large-scale and efficient bearing manufacturing.

[0030] Furthermore, the first baffle 7 is hingedly disposed in the storage box 5 and is located at the opening 502. The first baffle 7 blocks or cancels blocking of the opening 502 after swinging.

[0031] In this embodiment, in order to further improve the sealing and protection of the storage box 5, a first baffle 7 is hingedly provided at the opening 502 in the storage box 5. The first baffle 7 can be flexibly swung to cover or open the opening 502. This design not only helps to maintain the cleanliness of the internal environment of the storage space 501, but also effectively prevents external dust, debris and coolant from entering the storage space 501, thereby better protecting the unused wear parts 3.

[0032] As a preferred solution, a torsion spring is installed at the hinged portion between the first baffle 7 and the storage box 5. When the grinding piece 3 needs to be moved out of or into the storage space 501, it will first contact the first baffle 7 located at the passage 502. As the grinding piece 3 continues to move, its front end will push the first baffle 7 to swing inward, so that the passage 502 is gradually opened. Once the grinding piece 3 completely passes through the passage 502, the first baffle 7 will automatically reset and close the passage 502 under the action of the torsion spring, and restore the closed state of the storage space 501. The design of the torsion spring enables the first baffle 7 to have a certain pre-tightening force. When there is no external force, the first baffle 7 will naturally remain in a closed state. This automatic opening and closing mechanism greatly simplifies the operating process, and an efficient and reliable storage and removal process of the grinding piece 3 can be achieved without additional manual intervention. Through the design of the above-mentioned first baffle 7 and torsion spring combination, the entire system can ensure high efficiency while also having good protection performance, thereby providing more stable and reliable support for grinding processing.

[0033] Furthermore, the storage space 501 also has a window 503, which is located at the upper part of the storage space 501; the grinding piece 3 is a split structure, divided into a sliding part 304 and a grinding part 303, the sliding part 304 includes a first sliding part 301 and a second sliding part 302, the second sliding part 302 has a connecting port 305, and the grinding part 303 has a connecting part 306 that is plugged into the connecting port 305, and the connecting port 305 and the connecting part 306 are both polygonal structures, and also include: a second baffle 8, which is detachably arranged at the window 503.

[0034] In this embodiment, in order to facilitate the staff to observe and maintain the grinding parts 3 in the storage space 501, a window 503 is specially provided on the upper part of the storage space 501. This window 503 is large enough to accommodate the entire grinding part 303, so that the grinding part 303 can be directly taken out or put in. The design of the window 503 not only improves the convenience of operation, but also allows a quick inspection of the internal conditions without opening the storage box 5. Second baffle 8: A removable second baffle 8 is installed at the window 503, and its main function is to cover the window 503 when the storage space 501 is not needed to maintain the closedness and cleanliness of the storage space 501. As a preferred solution, the second baffle 8 is made of transparent material. This allows workers to clearly see the situation in the storage space 501 even when the baffle is closed, which is convenient for daily monitoring and management. When the grinding part 3 needs to be replaced or repaired, the storage space 501 can be easily accessed by simply removing the second baffle 8, which simplifies the maintenance process and reduces downtime. The grinding part 3 adopts a split structure, which is divided into two parts: the sliding part 304 and the grinding part 303. Such a design is conducive to replacing the worn parts separately and prolonging the service life of the whole system. The first sliding part 301 is responsible for moving in the first slide groove 101 of the column 1, while the second sliding part 302 is used to connect with the grinding part 303 and has a connection port 305. The grinding part 303 is provided with a polygonal connection part 306 matching the connection port 305 on the second sliding part 302. This polygonal structure ensures a good radial connection between the two and prevents relative rotation, thereby improving the overall stability and precision. The connection port 305 of the second sliding part 302 and the connection part 306 of the grinding part 303 are both designed as polygonal structures, which helps to achieve stable radial positioning and avoid loosening caused by factors such as vibration during operation. In order to further improve the axial stability, the second sliding part 302 can be provided with a threaded hole, and the connection part 306 of the grinding part 303 is also provided with a threaded groove accordingly. When the two are plugged in, they can be further reinforced by inserting a connecting bolt to ensure that the grinding part 303 is firmly fixed on the sliding part 304, reducing any unnecessary displacement or loosening risk. The above-mentioned improved design not only enhances the reliability and durability of the grinding system, but also greatly facilitates maintenance operations, improves production efficiency, and ensures the consistency of processing quality.

[0035] Furthermore, it also includes: a first clamping member 9, the first clamping member 9 is movably arranged, and has a first clamping portion 901, and the first clamping portion 901 is semi-circular; a second clamping member 10, the second clamping member 10 is movably arranged, and has a second clamping portion 1001, and the second clamping portion 1001 is semi-circular; after the first clamping member 9 and the second clamping member 10 move, the first clamping portion 901 and the second clamping portion 1001 jointly clamp the grinding piece 3 located at the grinding station 401. It also includes: a first gear 11, the first gear 11 is rotatably arranged, and the first clamping member 9 is arranged on the first gear 11; a second gear 12, the second gear 12 is rotatably arranged, and the second clamping member is arranged on the second gear 12; a third gear 13, the third gear 13 is rotatably arranged, and is located between the first gear 11 and the second gear 12, and meshes with the first gear 11 and the second gear 12. In this embodiment, in order to further improve the stability of the grinding piece 3 during the grinding process, a first clamping member 9 and a second clamping member are specially provided. As a preferred solution, the first clamping member 9 and the second clamping member are both designed as an annular structure. Each clamping member includes a semi-annular first clamping portion 901 or a second clamping portion 1001. The two clamping portions are respectively located on both sides of the grinding piece 3 to be processed, and can apply uniform pressure to the grinding piece 3 from opposite directions, thereby ensuring that it remains stable during the entire processing process.

[0036] The clamping action is achieved by driving the third gear 13 to rotate by the driving motor. The third gear 13 is located between the first gear 11 and the second gear 12. When it starts to rotate, it will cause the first gear 11 and the second gear 12 to rotate in opposite directions. This reverse movement allows the first clamping part 901 and the second clamping part 1001 to move inward from both sides of the grinding piece 3 at the same time, and finally tightly clamp the grinding piece 3, greatly enhancing its positioning accuracy under high-speed rotation and high-pressure cutting conditions. When the worn grinding piece 3 needs to be replaced, the third gear 13 is first rotated in the opposite direction by controlling the driving motor. With the reverse rotation of the third gear 13, the first gear 11 and the second gear 12 will also rotate in the opposite direction, causing the first clamping part 901 and the second clamping part 1001 to move away from each other, thereby releasing the clamping force on the current grinding piece 3. The worn grinding piece 3 can be moved out of the processing area by rotating the cylinder 1 and sent to the storage space 501; at the same time, the new grinding piece 3 will be moved to the corresponding working position. After the new grinding piece 3 is in place, the drive motor is started again, and the third gear 13 is rotated in the forward direction according to the same principle as above, so that the first clamping member 9 and the second clamping member re-clamp the newly installed grinding piece 3 to prepare for the next round of grinding operation. Through such a precise and efficient clamping and releasing system, not only the stability of the workpiece during the grinding process is significantly improved, but also the operation steps of replacing the grinding piece 3 are greatly simplified, the downtime is effectively shortened, and the operation efficiency of the overall production line is improved. In addition, this design can also adapt to grinding pieces 3 of different sizes and specifications, increasing the versatility and flexibility of the equipment.

[0037] Furthermore, it also includes: a rotating disk 14, the rotating disk 14 is sleeved on the column 1 and is coaxial with the column 1, a toothed disk 15, the toothed disk 15 is sleeved on the rotating disk 14, and the toothed disk 15 has a plurality of circumferentially arranged ratchet grooves 1501; a spherical pawl portion 16, the spherical pawl portion 16 is slidably arranged on the rotating disk 14, is arranged in a plurality of circles, and slides into the ratchet groove 1501 after sliding; an elastic member 17, one end of the elastic member 17 acts on the spherical pawl portion 16, and the other end acts on the rotating disk 14, providing the spherical pawl portion 16 with internal force stuck in the ratchet groove 1501; a fourth gear 18, the fourth gear 18 is rotatably arranged and meshes with the toothed disk 15.

[0038] The transport member 19 is movably arranged on the machine tool 4 , and has two members, which are respectively located at two grinding stations 401 , and are used to transport the outer ring of the bearing. The transport member 19 has a rack portion 1901 , and the rack portion 1901 is used to mesh with the gear disc 15 .

[0039] In this embodiment, the rotating disk 14 is sleeved on the column 1 and is coaxial with the column 1. The toothed disk 15 is rotatably sleeved on the rotating disk 14 and has a plurality of circumferentially arranged ratchet grooves 1501. Figure 5, the driving motor drives the fourth gear 18 to rotate, and further drives the toothed disc 15 to rotate. Taking the clockwise direction as an example, when the toothed disc 15 rotates clockwise, it will not drive the rotating disc 14 to rotate through the spherical ratchet portion 16, that is, at this time, the column 1 and the rotating disc 14 do not rotate. After the toothed disc 15 rotates, it meshes with the rack portion 1901 of the transport member 19, driving the transport member 19 to move. After the transport member 19 moves, the transport member 19 is used to transport the outer ring of the bearing. When the transport member 19 moves, it can drive the processed bearing to enter the grinding station 401, and be grasped by a two-jaw chuck or a four-jaw chuck for processing, and can also drive the processed outer ring of the bearing to enter the next process. When the grinding piece 3 needs to be replaced, the fourth gear 18 can be used to drive the toothed disc 15 to rotate counterclockwise. At this time, the spherical pawl portion 16 is engaged with the ratchet groove 1501, driving the rotating disc 14 to rotate, thereby driving the column 1 to rotate. After the column 1 rotates, the grinding piece 3 can be driven to be replaced. At this time, the two transport parts 19 will have a temporary movement in the opposite direction to better reserve space for the replacement of the grinding piece 3. Through the rotation of the toothed disc 15, not only the movement and transportation of the two transport parts 19 is realized, but also the rotation of the column 1 is realized, and the replacement of the grinding piece 3 is further realized, which is more convenient and efficient.

[0040] The rotating disk 14 is sleeved on the column 1 and remains coaxial with the column 1. This design allows the rotating disk 14 to rotate synchronously with the rotation of the column 1, ensuring the coordination and consistency of the entire system. The toothed disk 15 is further sleeved on the rotating disk 14, and it has a plurality of circumferentially arranged ratchet grooves 1501. These ratchet grooves 1501 are key structures designed for the spherical pawl portion 16, allowing the spherical pawl portion 16 to slide and snap in therein, thereby achieving a locking or unlocking function in a specific direction. The spherical pawl portion 16 is arranged in a circumferential manner on the rotating disk 14 and can slide freely on the surface of the rotating disk 14. When they slide into the ratchet grooves 1501 of the toothed disk 15, they will be tightly stuck under the action of the elastic member 17, preventing the toothed disk 15 from rotating counterclockwise (or clockwise) relative to the rotating disk 14. One end of the elastic member 17 acts on the spherical pawl portion 16, and the other end is fixed on the rotating disk 14, providing sufficient force to stably clamp the spherical pawl portion 16 in the ratchet groove 1501. The fourth gear 18 is designed to be rotatable and meshed with the toothed disk 15. The rotation of the fourth gear 18 is controlled by the driving motor, thereby driving the rotation of the toothed disk 15. There are two transport members 19, which are respectively located at two grinding stations 401 of the machine tool 4. Each transport member 19 is equipped with a rack portion 1901, which meshes with the toothed disk 15. In this solution, only part of the transport member 19 is shown. As a preference, a ring-shaped conveying system with teeth can be set with reference to this part. In this way, when the toothed disk 15 rotates, the transport member 19 can be directly driven by the rack portion 1901 to move along a predetermined path, so as to send the outer ring of the bearing to be processed into the grinding station 401, or move the outer ring of the bearing that has been processed to the next process.

[0041] Specifically, an example is as follows: during normal processing, the driving motor drives the fourth gear 18 to rotate clockwise, thereby driving the toothed disc 15 to rotate clockwise. At this time, due to the action of the spherical pawl portion 16, the rotating disc 14 will not rotate with the toothed disc 15, that is, the column 1 remains stationary. The rotation of the toothed disc 15 will drive the transport member 19 to move through the rack portion 1901, thereby completing the transportation of the outer ring of the bearing. When the grinding piece 3 needs to be replaced, the driving motor is reversed to make the fourth gear 18 rotate counterclockwise. At this time, the spherical pawl portion 16 is engaged with the ratchet groove 1501 of the toothed disc 15, thereby driving the rotating disc 14 and the column 1 to rotate counterclockwise together. The rotation of the column 1 realizes the position replacement of the grinding piece 3. At the same time, in order to reserve space for the replacement of the grinding piece 3, the two transport members 19 will temporarily move in opposite directions and drive the outer ring of the bearing to be processed thereon to move away from the grinding station 401 for a short distance, and then return to the original position again to prepare for the next operation. Through the above design, not only efficient material transportation is achieved, but also the operation process of replacing the grinding piece 3 is simplified. Such a mechanical linkage mechanism ensures a high degree of automation and continuity of the production line, and significantly improves production efficiency. In addition, the design of combining the spherical pawl portion 16 with the elastic member 17 enhances the reliability and durability of the system and reduces maintenance requirements.

[0042] Furthermore, the machine tool 4 has a plurality of guide holes 402, which are located below the grinding station 401, and further includes: a guide plate 20, which is located below the plurality of guide holes 402 and above the toothed disc 15 for guiding the coolant.

[0043] In this embodiment, in order to effectively manage and recycle the coolant used in the grinding process, the machine tool 4 is specially designed with a plurality of guide holes 402 and a guide plate 20. These components work together to ensure that the coolant can be efficiently collected and reused while keeping the working area clean. The guide hole 402 is located below the grinding station 401. This arrangement ensures that the coolant dripping or splashing from the grinding area can flow directly into the collection system through the guide hole 402. The guide plate 20 is installed below the guide hole 402 and above the gear disc 15. This position selection not only prevents the coolant from directly contacting the gear disc 15 and its transmission components, but also provides a smooth flow path for the coolant.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
