Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to a bearing fixture for bearing production. Background Technology

[0002] Bearings are an important component in mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] In the manufacturing process of bearings, grinding is a crucial step. After initial machining, the surfaces of various bearing components, especially the steel ring, will exhibit unevenness, roughness, and machining marks. Grinding not only improves the surface finish of the steel ring, reduces the coefficient of friction, and minimizes wear and energy loss during operation, but also ensures the bearing's precision and stability at high speeds, effectively extending its service life.

[0004] Currently, the common method for grinding steel rings is to fix the ring in place using a positioning clamp, and then use a grinding fixture to perform the grinding operation. Specifically, existing grinding fixtures typically grind one side of the ring first when grinding the ring fixed in the positioning clamp. After grinding this side, the ring needs to be removed from the positioning clamp, the ground surface needs to be changed, and the ring needs to be clamped and limited again before the grinding fixture can continue to grind the other side.

[0005] However, during the process of changing the grinding surface of the steel ring, the grinding fixture has to be shut down for a long time, unable to operate continuously. This not only prolongs the grinding cycle of a single steel ring but also reduces the overall grinding efficiency, affecting the bearing production schedule and increasing production costs. Furthermore, a large amount of debris is generated during the grinding of the steel ring. This debris easily gets trapped inside the positioning fixture, and currently, it is mostly cleaned manually. However, manual cleaning has significant limitations; untimely or forgotten cleaning is common. Once debris remains in the positioning fixture, the steel ring is difficult to keep stable during grinding, directly affecting the flatness of the steel ring during grinding, leading to a decrease in grinding quality, and consequently affecting the overall performance and quality of the bearing.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] See Figures 1 to 4The bearing fixture for bearing production provided in this embodiment of the present invention includes a support platform 1, a clamping assembly 2, a grinding assembly 3, and a blowing assembly 4. The clamping assembly 2 is disposed on the support platform 1, and has at least two clamping spaces 20 along a first straight line direction. The clamping spaces 20 are used to clamp the steel ring to be processed. The grinding assembly 3 includes a moving body 31, a driving mechanism 32, and a grinding disc 33. The grinding disc 33 is connected to the moving body 31 through the driving mechanism 32. The grinding disc 33 is located above the clamping assembly 2. The driving mechanism 32 can drive the grinding disc 33 to move in a direction close to or away from the clamping spaces 20 and drive the grinding disc 33 to rotate. The moving body 31 is movably connected to the support platform 1 and can drive the grinding disc 33 to move along the first straight line direction. The blowing assembly 4 is disposed on the support platform 1, and includes multiple blowing nozzles 41. The blowing nozzles 41 face the clamping assembly 2 and are used to blow the clamping spaces 20.

[0038] The bearing fixture for bearing production proposed in this utility model has a support platform 1 that provides stable support for the entire fixture. The clamping assembly 2 is disposed on the support platform 1 and has at least two clamping spaces 20 along the first straight direction, which can clamp multiple steel rings to be processed at the same time. This allows for operations such as flipping and loading / unloading other steel rings while grinding one steel ring, avoiding long-term downtime of the processing fixture while waiting for the steel rings to be processed to be changed for grinding, and improving grinding efficiency. In the grinding assembly 3, the grinding disc 33 is connected to the moving body 31 via the drive mechanism 32 and is located above the clamping assembly 2. The drive mechanism 32 can both drive the grinding disc 33 to move towards or away from the clamping space 20 for grinding, and drive the grinding disc 33 to rotate to grind the steel ring to be processed. The moving body 31 is movably connected to the support platform 1, which can drive the grinding disc 33 to move along the first straight line, thereby grinding the steel ring to be processed in different positions of the clamping space 20. After completing the grinding operation of one steel ring to be processed, it can immediately move to grind the next steel ring to be processed without stopping and waiting, optimizing the grinding process and improving the flexibility and convenience of grinding. The blowing assembly 4, through multiple blowing nozzles 41 facing the clamping assembly 2, can promptly blow the clamping space 20, avoiding the problem of debris remaining in the positioning fixture, which would cause uneven grinding of the steel ring to be processed and a decrease in grinding quality, ensuring the flatness of the steel ring to be ground, and thus ensuring the overall performance and quality of the bearing. In summary, the bearing fixture used in bearing production effectively improves the grinding efficiency and quality of bearing steel rings through the coordinated work of the clamping component 2, the grinding component 3, and the blowing component 4.

[0039] It is understood that the steel ring to be processed in this embodiment is only an example and not the only limitation on its applicability. In practical applications, the structural design of this fixture is also applicable to other workpieces with similar requirements, such as gears, flanges, and sealing rings. For workpieces of different shapes or sizes, it is only necessary to adjust the distance between the movable clamping arm 23 and the fixed clamping arm 22 in the clamping space 20 according to their outer diameter, or to change to a suitable type of grinding disc 33 (such as a flat grinding disc or a curved grinding disc), all of which can be applied to the bearing fixture for bearing production provided by this utility model.

[0040] The specific structure and working principle of each component of the bearing fixture used in bearing production are described in detail below.

[0041] The support platform 1 is used to support and install the overall fixture. It can be table-shaped, platform-shaped, or pier-shaped. It adopts an integral or modular structure design. The top forms a bearing surface for fixing the clamping component 2, grinding component 3, and blowing component 4.

[0042] For ease of description in conjunction with the accompanying drawings, the first straight line direction is defined here as the length direction of the support platform 1. The directions described below are based on the directions shown in the accompanying drawings, but are not limited thereto.

[0043] The clamping component 2 is set on the support platform 1 and is used to clamp and fix the steel ring to be processed through the clamping space 20.

[0044] Specifically, the clamping assembly 2 includes a fixed platform 21, fixed clamping arms 22, and a movable clamping arm 23. The fixed platform 21 is disposed on the support platform 1. Two fixed clamping arms 22 are disposed opposite each other at both ends of the fixed platform 21 along a first straight line. The movable clamping arm 23 is disposed between the two fixed clamping arms 22 and is movably connected to the fixed platform 21. The movable clamping arm 23 and the two fixed clamping arms 22 together form two clamping spaces 20. The movable clamping arm 23 can move toward either fixed clamping arm 22 so that one clamping space 20 is in a clamped state and the other clamping space 20 is in a relaxed state.

[0045] In use, when a steel ring to be processed needs to be clamped, the operator places the first steel ring into the clamping space 20 between one of the fixed clamping arms 22 and the movable clamping arm 23. The movable clamping arm 23 is then driven to move towards the corresponding fixed clamping arm 22, causing the movable clamping arm 23 and the corresponding fixed clamping arm 22 to clamp the steel ring. At this time, the clamping space 20 between the other fixed clamping arm 22 and the movable clamping arm 23 is relaxed due to the increased distance between them, facilitating the insertion of the second steel ring. After the first steel ring is polished, the movable clamping arm 23 moves towards the other fixed clamping arm 22, releasing the first steel ring that has been processed on one side, and simultaneously clamping the second steel ring. The relaxed clamping space 20 can then be used for unloading or flipping the steel ring. The tightness of the clamping spaces 20 on both sides can be switched by the unidirectional sliding of the movable clamping arm 23, achieving alternating fixing and releasing of the steel rings without repeatedly disassembling and reassembling the fixture, simplifying the operation process.

[0046] Preferably, the fixed clamping arms 22 are semi-circular, and the two fixed clamping arms 22 are symmetrically arranged. The movable clamping arms 23 are two semi-circular shapes arranged opposite each other, with the concave surfaces of the movable clamping arms 23 facing each other. When the movable clamping arm 23 moves close to either fixed clamping arm 22, the movable clamping arm 23 and the corresponding fixed clamping arm 22 engage to form a circular clamping space 20. The circular clamping space 20 is more compatible with the shape of the steel ring to be processed, and can better fit the steel ring to be processed, providing all-round and uniform support and clamping force for the steel ring to be processed. This effectively avoids the steel ring to be processed from shaking or shifting due to uneven force during the grinding process, thereby improving the stability of the steel ring to be processed during grinding.

[0047] It is understood that the structure of forming a double clamping space 20 by cooperating a single movable clamping arm 23 with two fixed clamping arms 22 in this embodiment is only a preferred implementation. In actual applications, it can be flexibly expanded according to processing requirements. For example, three fixed clamping arms 22 can be arranged at intervals along a first straight line, with an independently movable clamping arm unit set between each two adjacent fixed clamping arms 22, thereby forming four alternately working clamping spaces 20. Each movable clamping arm 23 unit can adjust the distance between adjacent fixed clamping arms 22 through individual drive or linkage control, thereby adapting to scenarios of multi-station synchronous processing or alternating loading and unloading. Such variant designs are all equivalent extensions of the clamping component 2 structure of this solution and do not constitute a limitation on the number and arrangement of clamping spaces 20.

[0048] Regarding the driving method of the movable clamping arm 23, in this embodiment, the fixed platform 21 has an installation space inside, the top of the fixed platform 21 has a guide groove 211 extending along the first straight line direction, the bottom of the movable clamping arm 23 is provided with a slider 24, the slider 24 is slidably connected to the guide groove 211, the installation space is provided with a lead screw 25 extending along the first straight line direction, one end of the lead screw 25 is provided with a drive motor 26, which is used to drive the lead screw 25 to rotate around its own axis, and the slider 24 is sleeved and threadedly connected to the lead screw 25. When it is necessary to adjust the position of the movable clamping arm 23 and change the state of the two clamping spaces 20, the drive motor 26 is started. The drive motor 26 drives the lead screw 25 to rotate around its own axis. Since the slider 24 is sleeved and threadedly connected to the lead screw 25, and the slider 24 is slidably connected in the guide groove 211 extending along the first straight line direction on the top of the fixed platform 21, the rotation of the lead screw 25 will cause the slider 24 to move linearly along the guide groove 211, thereby driving the movable clamping arm 23 connected to the slider 24 to move along the first straight line direction, so that the movable clamping arm 23 moves closer to or away from the fixed clamping arm 22, so that one of the clamping spaces 20 is in a clamped state and the other is in a relaxed state. The aforementioned lead screw 25 transmission mechanism converts the rotational motion of the motor into the high-precision linear displacement of the slider 24 through threaded engagement. This enables precise control of the moving distance of the movable clamping arm 23, ensuring that the clamping force is evenly applied to the surface of the steel ring to be processed. At the same time, the cooperation between the guide groove 211 and the slider 24 provides a stable guide for the movement of the movable clamping arm 23, ensuring that the movable clamping arm 23 moves smoothly along the predetermined first linear direction and avoiding deviation, thereby further ensuring the stability of the clamping of the steel ring to be processed.

[0049] Preferably, guide rods 212 extending along a first straight line are provided on both sides of the fixed platform 21, and sliding sleeves 231 are fixedly connected to both sides of the movable clamping arm 23, with the sliding sleeves 231 slidably connected to the corresponding guide rods 212. Thus, the guide grooves 211 and guide rods 212 form a double-layer guide, effectively dispersing the lateral force borne by the movable clamping arm 23 when clamping the steel ring, preventing the movable clamping arm 23 from tilting or shifting, and further improving the stability of the movable clamping arm 23 during movement.

[0050] In addition, limit seats 213 are provided at both ends of the guide rod 212. The limit seats 213 can limit the range of movement of the sliding sleeve 231 on the guide rod 212, effectively preventing the movable clamping arm 23 from detaching from the guide rod 212 due to excessive movement, ensuring that the movable clamping arm 23 always moves stably within a reasonable stroke. At the same time, the limit seats 213 effectively support both ends of the guide rod 212 through end fixing, improving the stability of the guide rod 212 fixation.

[0051] It is understood that the method of moving the movable clamping arm 23 via the lead screw 25 in this embodiment is only one specific implementation and not the only limitation on the drive structure of this solution. In other optional embodiments, the drive adjustment function of the movable clamping arm 23 can also be achieved by hydraulic cylinder push-pull, pneumatic cylinder extension and retraction, linear motor direct drive, gear and rack meshing, or pulley synchronous belt drive, etc. Although the above alternative solutions have different structural forms, they can all achieve precise displacement of the movable clamping arm 23 along the first linear direction, thereby adjusting the tightness of the clamping space 20. Therefore, those skilled in the art can flexibly choose the drive form according to the actual working conditions. As long as the technical means can meet the functional requirements of the clamping component 2 in terms of movement stability, positioning accuracy, and response speed, they should all be regarded as equivalent replacements or extensions of the drive mechanism 32 of this solution.

[0052] The grinding assembly 3 is used to perform the grinding process on the steel ring to be processed. The drive mechanism 32 is used to drive the grinding disc 33 to move in a direction close to or away from the clamping space 20 and to drive the grinding disc 33 to rotate.

[0053] Specifically, the drive mechanism 32 includes a telescopic motor 321 and a rotary motor 322. The bottom of the telescopic motor 321 is connected to the moving body 31, and the telescopic end of the telescopic motor 321 is connected to the rotary motor 322. The output end of the rotary motor 322 is detachably connected to the grinding disc 33. In use, the telescopic motor 321 is started, its telescopic end extends, driving the connected rotary motor 322 and the grinding disc 33 to move along the direction close to the steel ring in the clamping space 20 until the grinding disc 33 contacts the surface of the steel ring to be processed at a suitable grinding distance. Then, the rotary motor 322 is started, its output end drives the detachably connected grinding disc 33 to rotate at high speed, thereby performing a grinding operation on the surface of the steel ring. After grinding one steel ring to be processed, the rotary motor 322 stops, the telescopic motor 321 retracts, and the grinding disc 33 moves away from the steel ring for subsequent operations. The grinding disc 33 and the output end of the rotary motor 322 are detachably connected, which makes it convenient to replace the grinding disc 33 in a timely manner after it wears out, ensuring the consistency of the grinding effect, extending the service life of the entire grinding assembly 3, and reducing equipment maintenance costs.

[0054] The telescopic motor 321 and the rotary motor 322 are common motor devices in this field. Their working principles and specific structures will not be elaborated here.

[0055] The grinding disc 33 includes a disc body and a connecting part. The disc body has a circular structure and is made of a wear-resistant abrasive material with suitable hardness, such as silicon carbide or alumina. Its surface is set with specific abrasive textures according to the grinding requirements of the steel ring to be processed, so as to improve grinding efficiency and quality. The connecting part is located at the center of the disc body and includes a connecting sleeve with internal threads. The output end of the rotary motor 322 is designed with an external thread structure, which matches the internal thread of the connecting sleeve. When the grinding disc 33 needs to be installed, the connecting sleeve is aligned with the output end of the rotary motor 322. By rotating the disc body, the internal thread of the connecting sleeve is screwed into the external thread of the motor output end, thereby achieving a stable connection between the grinding disc 33 and the output end of the rotary motor 322. If wear occurs during the use of the grinding disc 33, simply rotate the disc body in the opposite direction and unscrew the connecting sleeve from the output end of the rotary motor 322 to easily remove the worn grinding disc 33 and replace it with a new grinding disc 33, completing a quick replacement.

[0056] Preferably, an angle adjustment mechanism is provided between the rotary motor 322 and the grinding disc 33. The angle adjustment mechanism includes a hinged base and an electric push rod. One end of the hinged base is connected to the output end of the rotary motor 322, and the other end is detachably connected to the grinding disc 33. The electric push rod is fixed to the side of the rotary motor 322, and its output end is hinged to the outer edge of the hinged base. When it is necessary to adjust the tilt angle of the grinding disc 33, the electric push rod extends and retracts, pushing the hinged base to rotate, thereby changing the contact angle between the grinding disc 33 and the surface of the steel ring to be processed, so as to grind the side edge and other parts of the steel ring to be processed. At the same time, it can adapt to curved surfaces, inclined surfaces and other irregular structures, improving the adaptability and versatility of bearing fixtures used in bearing production.

[0057] The support platform 1 is used to fix and install the drive mechanism 32, and also to adjust the position of the grinding disc 33 so that it can grind the steel rings to be processed in different clamping spaces 20. A guide plate 11 extending along a first straight line is formed on the support platform 1. A movable sleeve 311 is provided at the bottom of the moving body 31. The movable sleeve 311 is fitted and slidably connected to the guide plate 11. A drive component is provided on the support platform 1 to drive the movable sleeve 311 to move along the guide plate 11.

[0058] For example, a cylinder is selected as the driving component. The cylinder is mounted on the support platform 1 along the extension direction of the guide plate 11, and the cylinder body is fixed on the support platform 1. The end of the piston rod of the cylinder is connected to the movable sleeve 311 at the bottom of the moving body 31.

[0059] When it is necessary to drive the moving body 31 to move along the guide plate 11, the extension and retraction of the piston rod is achieved by controlling the air intake and exhaust of the cylinder. When compressed air is introduced into the cylinder, the piston rod extends, pushing the movable sleeve 311 and the moving body 31 connected thereto to move in one direction along the guide plate 11; when the cylinder exhausts air, the piston rod retracts under the action of the return spring, driving the moving body 31 to move in the opposite direction.

[0060] In addition, the drive components can also adopt a gear and rack meshing structure, a synchronous belt pulley structure, or a lead screw and nut structure, etc., which will not be elaborated here.

[0061] The purging assembly 4 is used to purge the clamping space 20. Specifically, the purging assembly 4 includes an air pipe 42 and an air pump 43. The air pipe 42 is set on the support platform 1, and the air pump 43 is connected to the air pipe 42 and is used to pump gas into the air pipe 42. The air pump 43 provides a continuous and sufficient air source for purging, ensuring the purging force and effect. Multiple air holes are opened through the air pipe 42, and each air hole is equipped with a purging nozzle 41. The position of the purging nozzle 41 can be precisely arranged according to the structure of the clamping assembly 2 and the distribution of the area to be purged, so as to achieve all-round and dead-angle purging of the clamping space 20, and further improve the purging effect.

[0062] Preferably, the blowing assembly 4 further includes an attitude adjustment unit connected to the air pipe 42, which is used to drive the air pipe 42 to rotate around its own circumference to adjust the blowing angle of the blowing nozzle 41. This allows the blowing nozzle 41 to be aimed at the area where debris is easily generated and accumulated by adjusting the blowing angle when dealing with steel rings of different shapes and sizes or when the location and distribution of debris during the grinding of the steel rings. This achieves more precise and efficient blowing, ensuring that debris in the clamping space 20 can be cleaned in a timely and effective manner regardless of the working conditions.

[0063] Specifically, the attitude adjustment unit includes a rotary joint and an angle adjustment motor. The rotary joint is installed at the connection between the air pipe 42 and the support platform 1, and the inner ring of the rotary joint is connected to the air pipe 42. The angle adjustment motor is fixed on the support platform 1, and the output shaft of the angle adjustment motor is connected to the outer ring of the rotary joint through a coupling. When it is necessary to adjust the blowing angle of the blowing nozzle 41, the angle adjustment motor is started. The output shaft of the angle adjustment motor drives the outer ring of the rotary joint to rotate, which in turn drives the air pipe 42 connected to it to rotate circumferentially, thereby realizing the adjustment of the blowing angle of the blowing nozzle 41.

[0064] The following describes the specific usage process of the bearing fixture used in the production of this bearing.

[0065] First, the operator places the first steel ring to be processed into the clamping space 20 between the fixed clamping arm 22 and the movable clamping arm 23 on one side. Then, the operator starts the drive motor 26 at one end of the lead screw 25. The drive motor 26 drives the lead screw 25 to rotate. The slider 24, which is threaded to the lead screw 25 and slides in the guide groove 211, synchronously drives the movable clamping arm 23 to move towards the corresponding fixed clamping arm 22, thereby clamping the first steel ring to be processed. At this time, the clamping space 20 between the fixed clamping arm 22 and the movable clamping arm 23 on the other side is in a relaxed state, and the second steel ring to be processed can be placed in.

[0066] Next, the drive unit on the support platform 1 is activated. By controlling the intake and exhaust of the cylinder, the piston rod is extended and retracted, pushing the movable sleeve 311 connected to the piston rod at the bottom of the moving body 31 to move along the guide plate 11 extending along the first straight line on the support platform 1, thereby moving the entire grinding assembly 3 to a suitable position above the first steel ring to be processed.

[0067] Then, the telescopic motor 321 is started, and its telescopic end extends, driving the rotary motor 322 and the grinding disc 33 to approach the first steel ring to be processed, until the grinding disc 33 reaches a suitable grinding distance from the surface of the steel ring. Next, the rotary motor 322 is started, driving the grinding disc 33 to rotate at high speed to grind the surface of the steel ring.

[0068] During the grinding of the first steel ring to be processed, operations such as flipping and loading / unloading can be performed on the steel ring in the other clamping space 20. After the first steel ring to be processed is ground, the rotary motor 322 stops, and the telescopic motor 321 retracts, moving the grinding disc 33 away from the steel ring. Subsequently, the drive motor 26 reverses, driving the movable clamping arm 23 to move towards the fixed clamping arm 22 on the other side, releasing the first steel ring to be processed whose side has been ground, and simultaneously clamping the second steel ring to be processed. At this point, the clamping space 20, now in a relaxed state, can be used for unloading or flipping the steel ring to be processed. Simultaneously, the grinding assembly 3 moves above the second steel ring to be processed under the action of the drive component, repeating the grinding operation.

[0069] Throughout the polishing process, the blowing assembly 4 operates continuously. The air pump 43 pumps gas into the air pipe 42, and the gas blows through the blowing nozzle 41 with an air hole on the air pipe 42 to clean the clamping space 20 and remove the debris generated during polishing in a timely manner.

[0070] If the grinding disc 33 becomes worn, stop the rotating motor 322, rotate the grinding disc 33 in the opposite direction, unscrew the connecting sleeve from the output end of the rotating motor 322, easily remove the worn grinding disc 33, replace it with a new grinding disc 33, and continue grinding operations after completing the quick replacement.

[0071] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
