Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a rolling bearing support device. Background Technology

[0002] A rolling bearing support device is a device used to reliably fix, precisely align, and provide stable support for rolling bearings during testing, installation, or processing.

[0003] Existing patent CN219967375U discloses a non-marking support device for processing bearing rings. By setting two support rollers and one pressure roller, it provides multi-point clamping support for the outer side of the rolling bearing, which facilitates the processing of the rolling bearing while improving the support stability.

[0004] However, technicians discovered certain flaws in the design. The idler rollers of the device are fixed, and positioning and support are mainly achieved by adjusting the pressure rollers. This causes the center position of the bearing to shift when different models of bearings are used, requiring the processing equipment to be readjusted as well. This is not only time-consuming but also affects processing accuracy and efficiency. In addition, the device can only clamp from the outside and lacks limiting on the bearing end face. During processing, the bearing is prone to axial sliding or even falling off, which affects stability and poses safety hazards. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] Therefore, one objective of this utility model is to propose a rolling bearing support device that achieves automatic centering through multiple synchronously driven clamping tubes. Changing the bearing model does not require adjusting the processing equipment, which greatly improves efficiency and versatility. At the same time, the clamping tubes integrate an end face positioning structure, which effectively prevents the bearing from sliding axially during processing, ensuring processing safety and quality.

[0007] To achieve the above objectives, the first aspect of this utility model provides a rolling bearing support device, comprising: a support base, an encapsulation assembly, a center positioning assembly, and an end face clamping assembly. The encapsulation assembly includes an outer encapsulation ring, an inner encapsulation ring, and two side encapsulation plates. The outer encapsulation ring is fixedly connected to the top of the support base, the inner encapsulation ring is disposed inside the outer encapsulation ring, and the two side encapsulation plates are respectively fixedly connected to both sides of the outer and inner encapsulation rings. The center positioning assembly includes a driving mechanism and a positioning mechanism.

[0008] In addition, the rolling bearing support device proposed above according to this utility model may also have the following additional technical features: Specifically, the driving mechanism includes a first motor, a transmission gear, and a gear ring. The first motor is fixedly mounted on the top of the support base. The transmission gear is disposed inside the support base and is connected to the drive shaft of the first motor. The gear ring is disposed inside the outer ring of the enclosure and meshes with the transmission gear.

[0009] Specifically, the positioning mechanism includes a rotating collar, multiple baffles, multiple sleeves, multiple connecting rods, and multiple connecting shafts. The rotating collar is fixedly connected to the inner side of the gear ring. Multiple first limiting grooves are opened on the outer side of the rotating collar. Multiple mounting ports are opened on both sides of the rotating collar. Multiple baffles are fixedly installed on the inner side of the mounting ports. Multiple sleeves are fixedly connected to the outer side of the inner ring of the encapsulation. Second limiting grooves are opened on both sides of the sleeves. Multiple connecting rods are slidably sleeved on the inner side of the corresponding sleeves. Multiple connecting shafts are inserted through the inner side of the corresponding first limiting groove, second limiting groove, and connecting rod.

[0010] Specifically, the end face clamping assembly includes multiple clamping tubes, multiple bidirectional lead screws, and multiple second motors. The multiple clamping tubes are respectively fixedly connected to one end of the corresponding connecting rod. The multiple bidirectional lead screws are respectively rotatably installed inside the corresponding clamping tubes. Clamping plates are threaded to the outer ends of the two ends of the bidirectional lead screws. Multiple third limiting grooves are opened on the outer side of the clamping tubes. The clamping plates are slidably connected to the corresponding third limiting grooves. The multiple second motors are respectively fixedly installed at one end of the corresponding clamping tubes, and the multiple second motors are respectively connected to the corresponding bidirectional lead screws.

[0011] Compared with the prior art, the present invention has the following advantages: The device achieves automatic centering through a clamping tube that can move radially synchronously, adapting to different types of bearings, effectively avoiding the need to readjust the processing equipment when changing bearings, significantly improving efficiency and versatility. At the same time, the bidirectional clamping structure set in the clamping tube can firmly constrain the bearing from both ends, solving the problem of axial movement of the bearing during processing and improving processing safety.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The rolling bearing support device of this utility model is described below with reference to the accompanying drawings.

[0021] like Figures 1-5 As shown in the figure, a rolling bearing support device according to an embodiment of the present invention includes: a support base 1, an encapsulation component 2, a center positioning component 3, and an end face clamping component 4.

[0022] The encapsulation component 2 includes an outer encapsulation ring 21, an inner encapsulation ring 22, and two side encapsulation plates 23. The outer encapsulation ring 21 is fixedly connected to the top of the support base 1, the inner encapsulation ring 22 is disposed inside the outer encapsulation ring 21, and the two side encapsulation plates 23 are fixedly connected to the outer encapsulation ring 21 and the inner encapsulation ring 22 on both sides, respectively.

[0023] The center positioning component 3 includes a drive mechanism 31 and a positioning mechanism 32, wherein the drive mechanism 31 is located at the top of the support base 1 and the positioning mechanism 32 is located inside the encapsulation component 2.

[0024] The end face clamping component 4 is located inside the positioning mechanism 32.

[0025] Specifically, when technicians need to process rolling bearings, they will use this rolling bearing support device to position and support the rolling bearings.

[0026] First, the technicians place the rolling bearing to be processed in the reserved position inside the positioning mechanism 32.

[0027] Subsequently, the technicians started the drive mechanism 31, which drove the positioning mechanism 32 to start operating. The various transmission components in the positioning mechanism 32 worked together to synchronously retract inward from multiple radial directions, thereby automatically centering and gripping the outer ring of the bearing, completing the center positioning and radial support of the bearing.

[0028] Finally, the technicians activate the end face clamping assembly 4, which drives its actuators to move along the bearing axis, applying a balanced clamping force from both end faces simultaneously, thereby achieving end face positioning and axial constraint of the bearing.

[0029] At this point, both the radial and axial directions of the rolling bearing are reliably constrained, forming a stable overall support state. In this state, technicians can use machining equipment to perform subsequent machining operations on the precisely positioned rolling bearing.

[0030] In one embodiment of this utility model, such as Figures 3-5 As shown, the drive mechanism 31 includes a first motor 311, a transmission gear 312, and a gear ring 313. The first motor 311 is fixedly mounted on the top of the support base 1. The transmission gear 312 is located inside the support base 1 and is connected to the drive shaft of the first motor 311. The gear ring 313 is located inside the outer ring 21 and meshes with the transmission gear 312.

[0031] Specifically, a protective cover is provided on the inner side of the support base 1, and the protective cover is fixedly connected to the bottom of the outer ring 21 of the encapsulation. The transmission gear 312 is rotatably installed inside the dust cover, and the gear ring 313 is rotatably connected to the side encapsulation plates 23 on both sides. When the technician starts the first motor 311, the drive shaft of the first motor 311 drives the transmission gear 312 fixedly connected to it to rotate. The rotation of the transmission gear 312 drives the gear ring 313 to rotate between the two side encapsulation plates 23.

[0032] The positioning mechanism 32 includes a rotating collar 321, multiple baffles 324, multiple sleeves 325, multiple connecting rods 327, and multiple connecting shafts 328. The rotating collar 321 is fixedly connected to the inner side of the gear ring 313, and multiple first limiting grooves 322 are opened on the outer side of the rotating collar 321.

[0033] Multiple mounting ports 323 are provided on both sides of the rotating collar 321. Multiple baffles 324 are fixedly installed inside the mounting ports 323. Multiple sleeves 325 are fixedly connected to the outside of the inner ring 22. Second limiting grooves 326 are provided on both sides of the sleeves 325.

[0034] Multiple connecting rods 327 are slidably sleeved inside the corresponding sleeves 325, and multiple connecting shafts 328 are inserted through the corresponding first limiting groove 322, second limiting groove 326 and connecting rod 327.

[0035] Specifically, the rotation of the gear ring 313 drives the rotating collar 321, which is fixedly connected to it, to rotate synchronously on the outside of the inner ring 22 of the encapsulation. Multiple first limiting grooves 322 on the outside of the rotating collar 321 are arranged in an equiangular circular array, and their trajectories are oblique grooves not pointing towards the center. Multiple sleeves 325 fixed to the outside of the inner ring 22 are also arranged at equal angles, and their second limiting grooves 326 are straight grooves pointing towards the center of the rotating collar 321. When the rotating collar 321 rotates, the first limiting grooves 322 drive the inserted connecting shaft 328 to move, forcing the connecting shaft 328 to slide along the straight trajectory of the second limiting grooves 326. This causes the connecting shaft 328 to drive the corresponding connecting rod 327 to move radially within the sleeve 325, achieving synchronous convergence of multiple connecting rods 327 towards the center of the rotating collar 321.

[0036] The end face clamping assembly 4 includes multiple clamping tubes 41, multiple bidirectional lead screws 42, and multiple second motors 43.

[0037] Multiple clamping tubes 41 are fixedly connected to one end of the corresponding connecting rod 327. Multiple bidirectional lead screws 42 are rotatably installed inside the corresponding clamping tubes 41. Clamping plates 45 are threaded to the outer ends of the two ends of the bidirectional lead screws 42. Multiple third limiting grooves 44 are opened on the outer side of the clamping tubes 41. The clamping plates 45 are slidably connected to the corresponding third limiting grooves 44. Multiple second motors 43 are fixedly installed at one end of the corresponding clamping tubes 41, and the multiple second motors 43 are connected to the corresponding bidirectional lead screws 42.

[0038] It should be noted that the multiple second motors 43 described in this embodiment are centrally controlled by the same controller and can be started synchronously to ensure that a balanced clamping force is applied to multiple positions on both sides of the rolling bearing, effectively improving clamping stability.

[0039] Specifically, when multiple connecting rods 327 converge towards the center simultaneously, the clamping tubes 41 fixed to their ends grip the outer ring of the rolling bearing, achieving automatic centering and radial positioning of the bearing. Subsequently, all second motors 43 are simultaneously activated by the controller, driving each bidirectional lead screw 42 to rotate. Since the threads at both ends of the bidirectional lead screw 42 rotate in opposite directions, they can drive the clamping plates 45 at both ends to move towards each other along the third limiting groove 44, thereby stably clamping the rolling bearing from both end faces and completing the full positioning and reliable support of the bearing.

[0040] In summary, the rolling bearing support device of this utility model can achieve automatic centering and clamping of the bearing through multiple sets of synchronously radially moving clamping tubes 41. When changing different types of bearings, there is no need to readjust the processing equipment, which significantly reduces the calibration time of the processing equipment. The integrated end face bidirectional clamping mechanism can reliably constrain the bearing from both sides, effectively solving the problem of axial movement of the bearing during processing.
