Description

Anti-elliptical bearing ring production equipment Technical Field

[0001] This utility model relates to the field of bearing rings, and more specifically, to an anti-elliptical bearing ring production device. Background Technology

[0002] Bearing races are critical components of bearings, typically made of high-strength steel with precise geometry and surface finish. Their primary function is to support and guide rolling elements (such as steel balls or rollers), ensuring the bearing can withstand radial and axial loads and achieve smooth rotational motion. The design and manufacture of bearing races must meet stringent dimensional accuracy and surface quality requirements to reduce friction, minimize wear, and extend bearing life.

[0003] Grinding is a crucial step in the production of bearing rings. It ensures the dimensional accuracy and surface finish of the bearing rings, laying a solid foundation for the smooth operation of the bearings. Through fine grinding, burrs, oxide layers, and machining marks on the surface of the bearing rings can be removed to achieve the required roughness and geometry.

[0004] However, during the grinding process, existing technologies typically grind only in one direction, leading to uneven distribution of grinding force and uneven clamping force of the fixture. As a result, the bearing ring may inevitably develop an elliptical defect. This ellipticity will cause uneven stress distribution in the bearing ring during installation and use, thereby affecting the rotational accuracy and service life of the bearing.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0006] In view of the problems in the related technologies, this utility model proposes an anti-elliptical bearing ring production device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] An anti-elliptical bearing ring production device includes a housing, a control panel on one side of the top of the housing, a support frame at the top of the housing, and an adjustment component at the top of the support frame. Inside the top of the housing is a clamping component, and a bearing ring that mates with the adjustment component is fitted on the outer side of the top of the clamping component. The clamping component is used to clamp and rotate the bearing ring. The support frame is L-shaped, and the bends of the support frame are rounded.

[0009] Furthermore, in order to perform stable grinding operations on the bearing ring, the adjustment assembly includes an electric push rod 1 located at the top of the support frame. The output end of the electric push rod 1 is equipped with a connecting block. Several connecting rod groups are evenly arranged around the outside of the connecting block. Each connecting rod group consists of two sets of connecting rods 1 arranged vertically. On the other side of each connecting rod group, there is a movable plate that cooperates with the support frame. The top of each movable plate is equipped with a limiting protrusion, and the bottom of each movable plate is equipped with a grinding block that cooperates with the bearing ring. Several limiting grooves 1 that cooperate with the limiting protrusions are opened at the inner top of the support frame. The limiting protrusions are convex in shape, and the grinding blocks are all curved on the side near the bearing ring.

[0010] Furthermore, in order to clamp and fix the bearing ring and assist in the grinding operation of the bearing ring, the clamping assembly includes a motor located inside the top of the housing. The output end of the motor is equipped with a rotating plate, and the top of the rotating plate is uniformly equipped with several support columns. The top of the support columns is equipped with a support seat. The top of the support seat is uniformly provided with four sets of limiting grooves II. Slider I is symmetrically arranged inside the limiting grooves II in the horizontal direction, and slider II is symmetrically arranged inside the limiting grooves II in the vertical direction. The bottom ends of the two sets of slider II are connected by symmetrically arranged electric push rods II. The bottom ends of slider I and slider II are equipped with connecting rods II. The other end of several connecting rods II is equipped with a limiting plate, and the limiting plate cooperates with the support column at the rotation axis of the motor output shaft. The top of slider I and slider II is equipped with a clamping plate that cooperates with the bearing ring. The connecting rod II is L-shaped, and the clamping plates are all arc-shaped structures.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. With the combined action of the control panel, support frame, adjustment components and clamping components, this utility model significantly reduces vibration and uneven stress during the grinding process by optimizing the distribution of grinding force, thus avoiding the elliptical defect in the geometric shape of the bearing ring. This not only improves the rotational accuracy and service life of the bearing ring, but also reduces the scrap rate, lowers production costs, and improves production efficiency and product quality stability.

[0013] 2. With the combined action of the adjustment component and the clamping component, this utility model can flexibly adjust the clamping force according to the size and shape of the bearing ring, ensuring that the workpiece remains stable during processing and avoiding deformation or ovality defects caused by uneven clamping. In addition, the relative position between the grinding block and the bearing ring can be precisely adjusted according to different processing requirements, optimizing the distribution of grinding force and reducing vibration and uneven stress. This not only improves the processing accuracy and surface quality, but also enhances the versatility of the equipment, enabling it to adapt to the production needs of bearing rings of various specifications and significantly improving the geometric accuracy and performance of the product.

[0022] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0023] According to an embodiment of the present invention, an anti-elliptical bearing ring production apparatus is provided.

[0024] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. As shown in Figures 1-5, the anti-elliptical bearing ring production device according to an embodiment of the present invention includes a housing 1, a control panel 2 is provided on one side of the top of the housing 1, a support frame 3 is provided at the top of the housing 1, and an adjustment component 4 is provided at the top of the support frame 3; a clamping component 5 is provided inside the top of the housing 1, and a bearing ring 6 that cooperates with the adjustment component 4 is sleeved on the outer side of the top of the clamping component 5, so that the bearing ring 6 can be clamped and rotated by the clamping component 5; the support frame 3 is L-shaped, and the bend of the support frame 3 is provided with rounded corners.

[0025] By utilizing the aforementioned technical solution, this utility model, through the coordinated action of the control panel 2, support frame 3, adjustment component 4, and clamping component 5, significantly reduces vibration and uneven stress during the grinding process by optimizing the distribution of grinding force. This avoids elliptical defects in the geometric shape of the bearing ring 6, which not only improves the rotational accuracy and service life of the bearing ring 6 but also reduces the scrap rate, lowers production costs, and enhances production efficiency and product quality stability. The coordinated action of the adjustment component 4 and clamping component 5 allows for flexible adjustment of the clamping force according to the size and shape of the bearing ring 6, ensuring workpiece stability during processing and preventing deformation or elliptic defects caused by uneven clamping. Furthermore, the optimized distribution of grinding force reduces vibration and uneven stress, improving processing accuracy and surface quality, enhancing the equipment's versatility, and enabling it to adapt to the production needs of various specifications of bearing ring 6, significantly improving the product's geometric accuracy and performance.

[0026] In one embodiment, the adjustment component 4 includes an electric push rod 401 disposed at the top of the support frame 3. The output end of the electric push rod 401 is provided with a connecting block 402. Several connecting rod groups are evenly arranged around the outer side of the connecting block 402. Each connecting rod group consists of two sets of vertically arranged connecting rods 403. On the other side of each connecting rod group, a movable plate 404 is provided to cooperate with the support frame 3. A limiting protrusion 405 is provided at the top of each movable plate 404, and a grinding block 406 is provided at the bottom of each movable plate 404 to cooperate with the bearing ring 6. Several limiting grooves 407 are provided at the inner top of the support frame 3 to cooperate with the limiting protrusions 405. The limiting protrusions 405 are convex in shape, and the grinding blocks 406 near the bearing ring 6 are all arc-shaped. This allows for stable grinding of the bearing ring 6.

[0027] The working principle of adjustment component 4 is as follows:

[0028] When it is necessary to reduce the distance between the grinding block 406 and the bearing ring 6 in the adjusting assembly 4, the electric push rod 401 in the adjusting assembly 4 is controlled and activated through the control panel 2. Under the extension action of the electric push rod 401, the connecting block 402 is driven to descend vertically. Under the descent action of the connecting block 402, the connecting rod 403 is driven to rotate. Under the rotation action of the connecting rod 403, and based on the cooperation of the limiting protrusion 405 and the limiting groove 407, several movable plates 404 are driven to move closer to each other. Under the action of several movable plates 404 moving closer to each other, several grinding blocks 406 are driven closer to each other, thereby reducing the distance between the grinding block 406 and the bearing ring 6.

[0029] When it is necessary to increase the distance between the grinding block 406 and the bearing ring 6 in the adjusting assembly 4, the electric push rod 401 in the adjusting assembly 4 is controlled and activated through the control panel 2. Under the shortening action of the electric push rod 401, the connecting block 402 is driven to rise vertically. Under the rising action of the connecting block 402, the connecting rod 403 is driven to rotate. Under the rotation action of the connecting rod 403, and based on the cooperation of the limiting protrusion 405 and the limiting groove 407, several movable plates 404 are driven to move away from each other. Under the action of the several movable plates 404 moving away from each other, several grinding blocks 406 are driven to move away from each other, thereby increasing the distance between the grinding block 406 and the bearing ring 6.

[0030] In one embodiment, the clamping assembly 5 includes a motor 501 disposed inside the top of the housing 1. A rotating plate 502 is disposed at the output end of the motor 501. A plurality of support columns 503 are evenly disposed at the top of the rotating plate 502, and a support base 504 is disposed at the top of each support column 503. Four sets of limiting grooves 505 are evenly distributed at the top of the support base 504. A slider 506 is symmetrically disposed inside the horizontal limiting grooves 505, and a slider 507 is symmetrically disposed inside the vertical limiting grooves 505. The bottom ends of the two sets of sliders 507 are connected by symmetrically disposed electric push rods 508. A connecting rod 509 is disposed at the bottom end of both sliders 506 and sliders 507. The other end of several connecting rods 509 is provided with a limiting plate 510 (connecting rods 509 and sliders 506 and limiting plate 510 are all connected by movable links, and connecting rods 509 and sliders 507 and limiting plate 510 are also connected by movable links). The limiting plate 510 cooperates with the support column 503 at the rotation axis of the output shaft of motor 501. The top of sliders 506 and sliders 507 are provided with clamping plates 511 that cooperate with bearing rings 6. The connecting rods 509 are L-shaped, and the clamping plates 511 are all arc-shaped. The sides of the clamping plates 511 that are far apart from each other are provided with anti-slip textures that cooperate with the inner side of bearing rings 6. Thus, the bearing rings 6 can be clamped and fixed and the grinding operation of bearing rings 6 can be completed.

[0031] The working principle of clamping component 5 is as follows:

[0032] When it is necessary to clamp the bearing ring 6, the electric push rod 508 in the clamping assembly 5 is controlled and activated through the control panel 2. Under the extension action of the output shaft of the electric push rod 508, the two sets of sliders 507 are driven to move away from each other along the limiting groove 505. Under the action of the two sets of sliders 507 moving away from each other, the connecting rod 509 and the limiting plate 510 are driven to rotate. At the same time, the limiting plate 510 rotates along the support column 503. Under the action of the rotation of the connecting rod 509, the two sets of sliders 506 are driven to move away from each other. At this time, the two sets of sliders 506 and the two sets of sliders 507 are all moving away from each other, which drives the clamping plate 511 to move away from each other, so that the clamping plate 511 is tightly attached to the inner wall of the bearing ring 6, thus achieving the clamping and fixing of the bearing ring 6.

[0033] When it is necessary to release the bearing ring 6, the electric push rod 508 in the clamping assembly 5 is controlled and activated through the control panel 2. Under the shortening action of the output shaft of the electric push rod 508, the two sets of sliders 507 are driven to move closer to each other along the limiting groove 505. Under the action of the two sets of sliders 507 moving closer to each other, the connecting rod 509 and the limiting plate 510 are driven to rotate. At the same time, the limiting plate 510 rotates along the support column 503. Under the action of the rotation of the connecting rod 509, the two sets of sliders 506 are driven to move closer to each other. At this time, the two sets of sliders 506 and the two sets of sliders 507 are all moving closer to each other, which drives the clamping plate 511 to move closer to each other, so that the clamping plate 511 releases contact with the bearing ring 6 and releases the clamping fixation of the bearing ring 6.

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] In practical application, the bearing ring 6 to be processed is first placed on the top of the clamping assembly 5. Then, the electric push rod 508 in the clamping assembly 5 is controlled and started through the control panel 2. Under the extension action of the output shaft of the electric push rod 508, the two sets of sliders 507 are driven to move away from each other along the limiting groove 505. Under the action of the two sets of sliders 507 moving away from each other, the connecting rod 509 and the limiting plate 510 are driven to rotate. At the same time, the limiting plate 510 rotates along the support column 503. Under the action of the rotation of the connecting rod 509, the two sets of sliders 506 are driven to move away from each other. At this time, the two sets of sliders 506 and the two sets of sliders 507 are all moving away from each other. The clamping plates 511 are moved away from each other, making them fit tightly against the inner wall of the bearing ring 6, thus clamping and fixing the bearing ring 6. Then, according to the actual situation, the control panel 2 controls and starts the adjustment component 4. Under the action of the adjustment component 4, the distance between the grinding block 406 in the adjustment component 4 and the bearing ring 6 is adjusted. Then, the control panel 2 controls and starts the motor 501. Under the rotation of the output shaft of the motor 501, the rotating plate 502 is driven to rotate. Based on the clamping and fixing of the bearing ring 6 by the clamping plates 511, the rotation of the rotating plate 502 drives the bearing ring 6 to rotate. Thus, with the cooperation of the grinding block 406, the processing and production of the bearing ring 6 is realized.

[0036] The working principle of adjustment component 4 and clamping component 5 is as described above.

[0037] In summary, by utilizing the above-mentioned technical solution of this utility model, the coordinated action of the control panel 2, support frame 3, adjustment component 4, and clamping component 5 significantly reduces vibration and uneven stress during the grinding process by optimizing the distribution of grinding force, thus avoiding elliptical defects in the geometric shape of the bearing ring 6. This not only improves the rotational accuracy and service life of the bearing ring 6 but also reduces the scrap rate, lowers production costs, and enhances production efficiency and product quality stability. With the coordinated action of the adjustment component 4 and clamping component 5, the clamping force can be flexibly adjusted according to the size and shape of the bearing ring 6, ensuring the workpiece remains stable during processing and avoiding deformation or elliptic defects caused by uneven clamping. Furthermore, the relative position between the grinding block 406 and the bearing ring 6 can be precisely adjusted according to different processing requirements, optimizing the distribution of grinding force and reducing vibration and uneven stress. This not only improves processing accuracy and surface quality but also enhances the versatility of the equipment, enabling it to adapt to the production needs of various specifications of bearing rings 6 and significantly improving the geometric accuracy and performance of the product.
