Description

Technical Field

[0001] This utility model belongs to the field of workpiece quality inspection and processing technology, and in particular relates to a clamping device for deburring bearing cages. Background Technology

[0002] The bearing cage is an important internal structural component of the bearing, usually made of metal. Therefore, the smoothness of its surface often affects the actual working performance and quality of the bearing. After the bearing cage is manufactured, its surface often needs to be deburred or ground. However, since different types of bearings have variations in cage models and structures, special attention needs to be paid to how the cage is clamped and fixed during the deburring and grinding process. Existing methods usually involve hand-holding or using a clamping mechanism to clamp the cage from opposite sides. This method may damage the cage's structure. Therefore, to solve this problem, we designed a clamping device for deburring bearing cages. Utility Model Content

[0003] The purpose of this invention is to provide a clamping device for deburring bearing cages, which solves the problem that existing clamping mechanisms are prone to damaging the cage structure.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a clamping device for deburring bearing cages, comprising a functional fixing seat, an adjusting seat, and a clamping assembly. The functional fixing seat is inserted and fixed below the adjusting seat, and the clamping assembly is disposed above the adjusting seat, with the two working in conjunction with each other. In conjunction with existing technology, the functional fixing seat is mainly used for functional expansion of this technical solution, such as how to install the cage onto the workstation to be processed after clamping and fixing it. The specific workstation to be processed includes a fixed platform or a rotary platform of a lathe. Therefore, a fixing rod is welded and fixed at the center of the lower surface of the functional fixing seat, which can meet the above working requirements.

[0006] Preferably, the clamping assembly includes several support plates, each a right-angled triangular plate structure. The number of support plates is at least four sets, arranged symmetrically above the adjusting seat. The adjusting seat has several adjusting grooves and several adjusting cavities inside, with the adjusting grooves and cavities interconnected and their number equal to that of the support plates. A driven rod is welded to the lower surface of each support plate, located inside the adjusting cavity and slidably engaging with it. In actual operation, the support plates slide outward from multiple angles and directions to support and clamp the inner diameter of the cage, thus adapting to bearing cages of different specifications. Furthermore, the triangular plate structures cooperate to form a truncated cone structure. When the cage is placed around the clamping assembly, and as the support plates slide outward, the cage slides up the inclined surface to the top, thus finding the optimal clamping position for the cage.

[0007] Preferably, a transmission cavity is formed on the lower surface of the adjustment cavity, and a linkage rod is connected to the rotating shaft on the inner surface of the transmission cavity. Both the linkage rod and the driven rod are worm gear structures and mesh with each other. A drive cavity is formed in the center of the adjustment seat. A driven gear is formed at one end of the linkage rod, and several driven gears are arranged inside the drive cavity. A drive rod is connected to the rotating shaft on the lower surface of the adjustment seat. A drive gear is welded to the upper end of the drive rod and is arranged inside the drive cavity. Both the drive gear and the driven gear are bevel gear structures, and several driven gears mesh with the drive gear. It should be noted that a knob is welded to the lower end of the drive rod. The knob is a hexagonal or dodecagonal nut structure, which is convenient for manual rotation or adjustment using a wrench. With the above structure, when the drive rod is rotated, the drive gear drives several driven gears to rotate using the gear meshing structure, which in turn drives the linkage rod to rotate. Then, the worm gear meshing structure drives the driven rod and the support clamp to slide, thereby achieving the clamping effect on the cage.

[0008] Preferably, the outer side of the support clamping plate has a storage cavity, and an auxiliary clamping arm is hinged to the inner surface of the storage cavity. The auxiliary clamping arm is an arc-shaped frame structure, and a vertical pressure plate is hinged to its clamping end. The vertical pressure plate is a fan-shaped plate structure. An auxiliary gear is welded and fixed to the hinged end of the auxiliary clamping arm in the storage cavity. A drive rack is slidably engaged with the inner surface of the storage cavity, and the drive rack meshes with the auxiliary gear. In combination with the above structure, when the support clamping plate slides, the fixed drive rack drives the auxiliary clamping arm to swing through the rack and gear meshing structure, thereby assisting in clamping the outer wall of the cage. This allows the equipment to adapt to cages of different specifications and models, thus preventing them from sliding sideways. On the other hand, it also avoids the support clamping plate from applying excessive pressure to the cage and applies reaction pressure from the outside to achieve internal force balance.

[0009] Preferably, an adjuster is bolted to the upper surface of the adjusting seat. The adjuster is disposed between several support plates, and one end of the drive rack extends into the interior of the adjuster. The connection end of the drive rack and the adjuster is provided with a threaded groove, forming a lead screw structure. It should be further noted that, in order to use cages of different thicknesses, an adjusting disc is provided inside the adjuster. The adjusting disc has a gear structure, and the end of the drive rack extending into the adjuster is linked with the adjusting disc through a gear meshing structure. This allows for fine-tuning of the clamping arm by rotating the adjusting disc when dealing with cages of different thicknesses. The adjuster has a built-in fine-tuning motor, and the output shaft of the fine-tuning motor is mechanically fixed to the adjusting disc.

[0010] Preferably, a clamping plate is welded and fixed to the upper end of the support clamping plate, and an anti-slip pad is adhered and fixed to the outer side of the clamping plate. A pressure pad is adhered to the outer side of the vertical pressure plate, and a number of support springs are fixedly connected between the outer side of the vertical pressure plate and the pressure pad. The vertical pressure plate and the anti-slip pad cooperate with each other.

[0011] This utility model has the following beneficial effects:

[0012] This utility model sets up a worm gear meshing linkage structure based on a gear meshing structure in the adjusting frame. By rotating the drive rod in one direction, the drive gear drives several driven gears to rotate through the gear meshing structure, which in turn drives the linkage rod to rotate. Then, the worm gear meshing structure drives the driven rod and the support clamp to slide, thereby achieving the clamping effect on the cage.

[0013] In addition, by setting up an auxiliary clamping arm driven by a drive rack, the auxiliary clamping arm swings due to the fixed drive rack using the rack and pinion meshing structure during the sliding of the support clamping plate, thereby assisting in clamping the outer wall of the cage. This allows the equipment to adapt to cages of different specifications and models, thus preventing them from slipping. On the other hand, it also avoids the support clamping plate from applying excessive pressure to the cage and applies reaction pressure from the outside, achieving internal force balance of the structure.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Please see Figures 1-6As shown, this utility model is a clamping device for deburring bearing cages, including a functional fixing seat 1, an adjusting seat 2, and a clamping assembly. The functional fixing seat 1 is inserted and fixed below the adjusting seat 2, and the clamping assembly is disposed above the adjusting seat 2, and the two are linked and cooperate with each other. In combination with the prior art, the functional fixing seat 1 is mainly used for the functional expansion of this technical solution, such as how to install the cage onto the workstation after clamping and fixing it. The specific workstation includes a fixed platform or a rotary platform of a lathe. Therefore, a fixing rod 23 is welded and fixed at the center of the lower surface of the functional fixing seat 1, which can meet the above working requirements.

[0027] Preferably, the clamping assembly includes several support plates 3, each a right-angled triangular plate structure. The number of support plates 3 is at least four sets, arranged symmetrically above the adjusting seat 2. The adjusting seat 2 has several adjusting grooves 4 and several adjusting cavities 5 inside, wherein the adjusting grooves 4 and adjusting cavities 5 are interconnected, and their number is the same as that of the support plates 3. A driven rod 6 is welded to the lower surface of the support plates 3, wherein the driven rod 6 is located inside the adjusting cavity 5 and slides and engages with the adjusting cavity 5. In actual operation, the several support plates 3 slide outward from multiple angles and directions to support and clamp the inner diameter of the cage, thereby adapting to bearing cages of different specifications. Furthermore, the several triangular plate structures cooperate to form a truncated cone structure. When the cage is placed around the clamping assembly, and during the outward sliding expansion of the several support plates 3, the cage slides up the inclined surface to the top, thus finding the optimal clamping position for the cage.

[0028] Preferably, a transmission cavity 7 is formed on the lower surface of the adjusting cavity 5, and a linkage rod 8 is connected to the rotating shaft on the inner surface of the transmission cavity 7. Both the linkage rod 8 and the driven rod 6 are worm gear structures and mesh with each other. A driving cavity 9 is formed in the center of the adjusting seat 2. A driven gear 10 is formed at one end of the linkage rod 8, and several driven gears 10 are disposed inside the driving cavity 9. A driving rod 11 is connected to the rotating shaft on the lower surface of the adjusting seat 2, and a driving gear 12 is welded to the upper end of the driving rod 11. The driving gear 12 is disposed inside the driving cavity 9. The driving gear 12 and the driven gear... All 10 gears are bevel gears, and several driven gears 10 mesh with the drive gear 12. It should be noted that a knob 24 is welded to the lower end of the drive rod 11. The knob 24 is a hexagonal or dodecagonal nut structure, which is convenient for manual rotation or adjustment using a wrench. In combination with the above structure, when the drive rod 11 is rotated, the drive gear 12 drives several driven gears 10 to rotate through the gear meshing structure, which in turn drives the linkage rod 8 to rotate. Then, the worm gear meshing structure drives the driven rod 6 and the support clamp 3 to slide, thereby achieving the clamping effect on the cage.

[0029] Preferably, the outer side of the support clamping plate 3 has a receiving cavity 13, and an auxiliary clamping arm 14 is hinged to the inner surface of the receiving cavity 13. The auxiliary clamping arm 14 is an arc-shaped frame structure, and a vertical pressure plate 15 is hinged to its clamping end. The vertical pressure plate 15 is a fan-shaped plate structure. An auxiliary gear 16 is welded and fixed to the hinged end of the auxiliary clamping arm 14 and the inner surface of the receiving cavity 13 is slidably engaged with a drive rack 17, and the drive rack 17 meshes with the auxiliary gear 16. In combination with the above structure, when the support clamping plate 3 slides, the fixed drive rack 17 drives the auxiliary clamping arm 14 to swing through the rack and gear meshing structure, thereby assisting in clamping the outer wall of the cage. This allows the equipment to adapt to cages of different specifications and models, thereby preventing them from sliding sideways. On the other hand, it can also prevent the support clamping plate 3 from applying excessive pressure to the cage and apply reaction pressure from the outside to achieve internal force balance.

[0030] Preferably, an adjuster 18 is bolted to the upper surface of the adjusting seat 2. The adjuster 18 is disposed between several support plates 3, and one end of the drive rack 17 extends into the interior of the adjuster 18.

It should be further noted that, in order to use cages of different thicknesses, an adjusting disc is provided inside the adjuster 18. The adjusting disc is a gear structure. At the same time, the end of the drive rack 17 extending into the adjuster 18 is linked with the adjusting disc through a gear meshing structure. Thus, when dealing with cages of different thicknesses, the clamping arm 14 can be finely adjusted by rotating the adjusting disc. The adjuster 18 has a built-in fine-tuning motor, and the output shaft of the fine-tuning motor is mechanically fixed to the adjusting disc.

[0031] Preferably, a clamping plate 19 is welded and fixed to the upper end of the support clamping plate 3, and an anti-slip pad 20 is glued and fixed to the outer side of the clamping plate 19.
