Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to an O-ring support plate mechanism. Background Technology

[0002] A common type of bearing on the market has one or two sealing grooves on its outer wall. O-rings need to be installed in the sealing grooves to increase the tightness between the bearing outer ring and the bearing housing, thereby preventing the outer ring from slipping during bearing operation, facilitating the installation of the bearing with radial clearance fit, and reducing vibration during bearing operation.

[0003] A published Chinese patent, CN109940376A, discloses an O-ring fastening mechanism, specifically relating to the field of O-ring fastening machines. It includes a motor mounting plate with a working base plate on top. Several parallel support columns are positioned between the motor mounting plate and the working base plate. A drive assembly is located at the center of the motor mounting plate, and a fastening assembly is provided on the surface of the working base plate. This invention fastens the O-ring onto multiple closing support claws. A linear stepper motor is activated, lifting the support cone and pushing the support plate radially open along a linear guide rail. The support claws then open the O-ring, facilitating the fastening process. This mechanism is compatible with O-rings of various diameters, achieving multi-purpose functionality and reducing equipment costs. During uncoupling, an uncoupling cylinder is activated, pushing the O-ring off the support claws. Subsequently, the linear stepper motor drives the support cone to retract, and the support plate and claws return to their original positions under the force of a return spring, improving the fastening efficiency. The disclosed patent describes a method where a support cone simultaneously pushes six radially distributed support plates, which are then reset by six return springs. However, the elastic coefficients of these return springs decay inconsistently after prolonged use, causing the support claws to fail to accurately return to their initial positions when they close, thus affecting the accuracy of subsequent ring fitting. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an O-ring support plate mechanism to solve the problem of inconsistent elastic coefficient decay after long-term use when using a return spring for the ring support action reset in the prior art.

[0005] To achieve the above and other related objectives, this utility model provides an O-ring support plate mechanism, including a support base, two support plates at the upper end of the support base, and a top plate mounted on the upper end of the two support plates.

[0006] A rotary motor is provided at the upper end of the support base and between the two support plates. A turntable is provided at the output end of the rotary motor, and multiple waist-shaped holes are provided on the turntable at equal intervals.

[0007] The top plate is provided with an opening module at the same number and position as the waist-shaped holes. The front end of the opening module is provided with a limiting block, which is adjustablely fitted in the waist-shaped holes. Multiple opening modules work together to open the O-rings along the circumferential direction.

[0008] In one embodiment of the present invention, the top plate has a through hole in the central area, the output end of the rotary motor passes through the through hole, and the turntable extends to the upper end of the top plate.

[0009] In one embodiment of this utility model, the expanding module includes:

[0010] A slide rail, which is mounted on the upper end of the top plate;

[0011] A slider that is slidably fitted onto a slide rail;

[0012] A strut fixing block is mounted on the slider, and the front end of the strut fixing block extends above the turntable;

[0013] Guide block, the guide block is mounted on the front end of the strut fixing block;

[0014] The front end of the guide block is provided with an L-shaped support hook.

[0015] In one embodiment of the present invention, the guide block is configured as a Z-shaped structure, with space between the front end of the guide block and the front end of the strut fixing block.

[0016] In one embodiment of this utility model, the limiting block is detachably mounted on the front end of the strut fixing block using a stud.

[0017] In one embodiment of this utility model, four waist-shaped holes and four expansion modules are provided. The four waist-shaped holes are symmetrically distributed on the turntable, and the four expansion modules are symmetrically distributed on the upper end of the top plate.

[0018] As described above, the O-ring support plate mechanism of this utility model has the following beneficial effects:

[0019] This invention employs a rotary motor to drive a turntable, causing the oblong hole to slide against the limiting block. This forces multiple expansion modules to move synchronously radially along the slide rail, achieving uniform circumferential expansion of the O-ring, improving the synchronicity of the expansion action, and thus enhancing the expansion effect. After expansion is complete, the rotary motor drives the turntable to reverse, automatically resetting it. This eliminates redundant components such as the retraction cylinder and return spring, simplifying the structure and effectively reducing the failure rate. The output end of the rotary motor passes through a through-hole in the top plate, creating a stacked structure between the turntable and the expansion modules, effectively improving the overall compactness of the mechanism. This invention uses mechanical constraints; multiple rotationally symmetrically distributed expansion modules and the oblong hole form a force balance system, ensuring a smooth and uniform O-ring expansion process, simplifying control logic, and better meeting the stability requirements of bearing manufacturing scenarios.

[0027] Please see Figures 1-3 This utility model provides an O-ring support plate mechanism, including a support base 1, two support plates 2 on the upper end of the support base 1, and a top plate 3 on the upper end of the two support plates 2; a rotary motor 4 is provided on the upper end of the support base 1 and between the two support plates 2, and a turntable 5 is provided on the output end of the rotary motor 4, with a plurality of waist-shaped holes 51 equidistantly arranged on the turntable 5; a through hole 31 is provided in the central area of ​​the top plate 3, the output end of the rotary motor 4 passes through the through hole 31, and the turntable 5 extends to the upper end of the top plate 3.

[0028] The top plate 3 has an upper end with a number of supporting modules 6 corresponding to the number and position of the waist-shaped holes 51. In one application scenario, there are four waist-shaped holes 51 and four supporting modules 6. The four waist-shaped holes 51 are symmetrically distributed on the turntable 5, and the four supporting modules 6 are symmetrically distributed on the upper end of the top plate 3. The design of the output end of the rotary motor 4 passing through the through hole 31 of the top plate 3 makes the turntable 5 and the supporting modules 6 form an upper and lower stacked structure, effectively improving the overall compactness of the mechanism.

[0029] The expansion module 6 includes a slide rail 61, a slider 62, a support rod fixing block 63, a guide block 64, an L-shaped support hook 65, and a limiting block 66.

The fit is in the waist-shaped hole 51; this utility model uses a rotary motor 4 to drive the turntable 5 to rotate, so that the waist-shaped hole 51 and the limiting block 66 slide fit together, forcing multiple expansion modules 6 to move synchronously radially along the slide rail 61, so that the O-ring expands evenly in the circumferential direction, improves the synchronicity of the ring support action, and thus improves the ring support effect; after the ring support is completed, the rotary motor 4 drives the turntable 5 to reverse so as to automatically reset, eliminating redundant parts such as the ring retraction cylinder and the reset spring, simplifying the structure and effectively reducing the failure rate.

[0030] The guide block 64 is configured with a Z-shaped structure, and there is space between the front end of the guide block 64 and the front end of the support rod fixing block 63; the limiting block 66 is detachably mounted on the front end of the support rod fixing block 63 using a stud. The stud is easy to assemble, disassemble, and replace the support module 6, which can quickly adapt to O-ring support rings of different diameters and reduce changeover time.

[0031] In summary, this invention employs mechanical constraints, where multiple rotationally symmetrically distributed opening modules 6 and the oblong hole 51 form a force balance system. This ensures a smooth and uniform O-ring opening process, simplifies control logic, and better meets the stability requirements of bearing manufacturing scenarios. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.
