Description

Technical Field

[0001] This utility model relates to the field of bearing assembly technology, and in particular to a bearing cage press-fitting device. Background Technology

[0002] A bearing cage, also known as a bearing retainer, is a bearing component that partially encloses all or part of the rolling elements and moves with them. It isolates the rolling elements and typically guides and holds them within the bearing. An existing hammer-type bearing cage pressing device (publication number CN 111376025 A) uses an intermittent rotating bearing clamping mechanism to place the bearing to be pressed into a bearing clamp slot. A motor-reducer integrated machine drives a partially rotating gear, which in turn drives a linkage gear to rotate 1 / 6 of a turn, moving the next bearing clamp slot to the bottom of the hammer-pressing mechanism. The hammer-pressing mechanism then presses the bearing cage in place again. One full rotation of the partially rotating gear drives the hammer-pressing mechanism to perform a downward hammering and return process, and also rotates the turntable 1 / 6 of a turn, thus completing the pressing work at the next station. However, after pressing the cage, the above device requires the bearing to be removed, increasing labor and reducing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a bearing cage press-fitting device to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A bearing cage pressing device includes a support mechanism, which includes a bracket with a top plate fixed to its upper end. A support column passing through the top plate is fixed to the bracket, and a beam is fixed to the upper end of the top plate. A feeding mechanism for pressing and unloading bearings is provided on the support mechanism, and a pressing mechanism is provided on the upper side of the feeding mechanism. The feeding mechanism includes a sleeve fitted on the support column, with a placement plate fixed to the upper end of the sleeve. Limit seats are evenly distributed around the upper circumference of the placement plate, and a pushing assembly is vertically arranged at the center of the limit seats. An intermittent rotation assembly is connected to the lower end of the sleeve. The pushing assembly includes a top column vertically passing through the center of the limit seats, with a universal wheel at the lower end of the top column. A spring is fitted on the top column above the universal wheel. An annular convex rail is provided at the upper end of the top plate corresponding to the universal wheel, with one section of the annular convex rail being protruding. A cylinder is fixed to the upper end of the support column, and a push plate is installed on the movable end of the cylinder, corresponding to the protruding section of the annular convex rail.

[0006] Further configuration: The sleeve is rotatably connected to the top plate, and the top column is slidably connected to the placement plate.

[0007] Further configuration: A groove is provided on the placement plate within the limiting seat, and a disc is fixed at the upper end of the top column, with the disc slidingly connected to the groove.

[0008] Further configuration: The intermittent rotation component includes a worm gear fixed to the lower end of the sleeve, a worm meshing on one side of the worm gear, the worm being mounted on the lower end of the top plate via a mounting base, and a servo motor connected to the rear end of the worm.

[0009] Further features: A guide platform is provided on one side of the raised section of the annular convex rail on the top plate, and a conveyor belt is provided below the guide platform.

[0010] Further configuration: The pressing mechanism includes a hydraulic column fixed to the upper end of the beam frame, and a pressing block is installed at the lower end of the hydraulic column, with the pressing block corresponding to the limit seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By using the push assembly and intermittent rotation assembly of the feeding mechanism, the retainer and bearing ring placed in the limiting seat are rotated to the lower side of the pressing mechanism for pressing through the intermittent rotation assembly. At the same time, as the placement plate rotates, the top column corresponding to the limiting seat rotates along with it. The universal wheel at the lower end of the top column rotates on the annular convex rail. When it rotates to the protruding part of the annular convex rail, the top column pushes the pressed bearing out of the limiting seat. The cylinder pushes the push plate to push the bearing out, which improves the convenience and efficiency of removing the pressed bearing. Attached Figure Description

[0026] In this embodiment: the feeding mechanism includes a sleeve 21 fitted onto the support column 13. A placement tray 22 is fixed to the upper end of the sleeve 21. Limit seats 23 are evenly distributed around the upper circumference of the placement tray 22. A pushing component is vertically arranged at the center of the limit seats 23. An intermittent rotation component is connected to the lower end of the sleeve 21. The pushing component includes a top column 24 that vertically passes through the center of the limit seats 23. A universal wheel 26 is arranged at the lower end of the top column 24. A spring 25 is fitted on the top column 24 above the universal wheel 26. The spring 25 ensures that the universal wheel 26 is initially rotated. Finally, it contacts the annular convex rail 27 at the bottom. The annular convex rail 27 is provided at the upper end of the top plate 12, corresponding to the position of the universal wheel 26. One section of the annular convex rail 27 is protruding. A cylinder 211 is fixed at the upper end of the support column 13. A push plate 212 is installed at the movable end of the cylinder 211. The push plate 212 corresponds to the protruding section on the annular convex rail 27. The sleeve 21 is rotatably connected to the top plate 12, and the top column 24 is slidably connected to the placement plate 22. A groove is provided on the placement plate 22 within the limiting seat 23. The upper end of the top column 24 is fixed with The disc is slidably connected to the groove; the retainer and bearing ring in the upper limit seat 23 of the placement disc 22 are intermittently rotated to the lower side of the pressure block 32 by the intermittent rotation assembly. At the same time, during the rotation of the placement disc 22, the top column 24 corresponding to the limit seat 23 rotates with the whole. The universal wheel 26 at the lower end of the top column 24 rotates on the annular convex rail 27. When it rotates to the protruding part of the annular convex rail 27, the top column 24 pushes the press-fitted bearing out of the limit seat 23. The cylinder 211 extends and pushes the push plate 212 to... The bearing is extended; the intermittent rotation assembly includes a worm gear 28 fixed to the lower end of the sleeve 21, a worm 29 meshing on one side of the worm gear 28, the worm 29 being mounted on the lower end of the top plate 12 via a mounting seat, and a servo motor 210 connected to the rear end of the worm 29. The servo motor 210 drives the worm 29 to mesh and rotate with the worm gear 28. By controlling the rotation amount of the servo motor 210, the worm gear 28 drives the sleeve 21 and the placement disk 22 to rotate intermittently. This is prior art in the field and will not be described in detail here.

[0027] A guide platform 4 is provided on one side of the protruding section of the annular convex rail 27 on the top plate 12. A conveyor belt 5 is provided on the lower side of the guide platform 4. The press-fitted bearing is pushed into the guide platform 4 by the extension of the cylinder 211 and the push plate 212, and then slid down and is sent out by the conveyor belt 5.

[0028] In this embodiment, the pressing mechanism includes a hydraulic column 31 fixed to the upper end of the beam frame 14. A pressing block 32 is installed at the lower end of the hydraulic column 31. The pressing block 32 corresponds to the limiting seat 23 vertically. When the placement plate 22 rotates, the bearing and retainer in the limiting seat 23 rotate to the lower side of the pressing block 32. The hydraulic column 31 extends and pushes the pressing block 32 to press the retainer into the bearing.

[0029] The working principle and usage process of this utility model are as follows: The bearing and cage to be pressed are placed in the limiting seat 23. The servo motor 210 drives the worm gear 29 to mesh and rotate with the worm wheel 28, so that the worm wheel 28 drives the sleeve 21 and the placement plate 22 to rotate intermittently. The cage and bearing ring in the limiting seat 23 are intermittently rotated to the underside of the pressing block 32. Then, the hydraulic column 31 extends and pushes the pressing block 32 to press the cage into the bearing. As the placement plate 22 continues to rotate, the top column 24 corresponding to the limiting seat 23 rotates with the whole. The universal wheel 26 at the lower end of the top column 24 rotates on the annular convex rail 27. When it rotates to the protruding part of the annular convex rail 27, the top column 24 pushes the pressed bearing out of the limiting seat 23. The cylinder 211 extends and pushes the push plate 212 to push the bearing into the guide table 4 and slide down. It is then sent out by the conveyor belt 5, so that the whole process is continuous and avoids manual handling of the bearing.
