Is pushed and slid, and the five balls 19 on the left side of the pushing and moving plate 18 are pushed into the assembly hole 32, and the balls 19 are located between the inner ring 47 and the outer ring 31. At that time, the push-moving plate 18 blocks the slide guide groove 21, and after the assembly is completed, the air pump 15 sucks air from the ventilation hole 14 and the expansion / contraction space 13, thereby causing the expansion / contraction air pipe 17. It is possible to prevent the ball 19 from rolling into the slide guide groove 21 again when it is contracted and assembled.

The steps of assembling the ball bearing and using the quality detection equipment of the present invention will be described in detail with reference to FIGS. 1 to 7 below.

At the initial stage, the slide block 34 is in the front limit position, and at this time, the slide gear 64 and the drive gear 63 are in the detached state, the slide shaft 41 and the meshing gear 38 are in the detached state, and the elevating block 26 The lower end is in contact with the lower inner wall of the working space 27, all the balls 19 are located in the storage space 57, and the stopper plate 52 blocks the communication groove 20.

At the time of use, the inner ring 47 is connected to the spline shaft 50 by the slide hole 48, the outer ring 31 is inserted between the holding plates 22 on both sides, the outer ring 31 is sandwiched under the elastic action of the pressing spring 24, and the lower end of the outer ring 31 is held. Contact the lower inner wall of the working space 27, and at this time, the small motor 35 is started, the connecting gear 45 is rotationally interlocked in the forward direction by the short shaft 69, and the spline shaft 50 is descended and interlocked by the elevating screw 40. Further, the inner ring 47 is lowered and interlocked to enter the assembly hole 32. At this time, the front end of the inner ring 47 comes into contact with the front inner wall of the assembly hole 32, and at this time, the small motor 35 is stopped.

The expansion and contraction spring 54 is energized, whereby the stop plate 52 is slid downward and the slide guide groove 21 and the storage space 57 are communicated with each other. At this time, the ball 19 in the storage space 57 connects the communication groove 20. When the count detection head 53 detects that the number of balls 19 rolled into the slide guide groove 21 has reached five, the expansion and contraction spring 54 is cut off. As a result, the communication groove 20 is blocked again, and at this time, the five balls 19 are located on the left side of the push-moving plate 18, and at this time, the air pipe 15 is operated, and further, in the ventilation hole 14 and the expansion and contraction space 13. Air is passed through, thereby extending the expansion and contraction air pipe 17, pushing and moving the plate 18 to slide, and further pushing the five balls 19 on the left side of the pushing and moving plate 18 into the assembly hole 32, and the balls 19 It is located between the inner ring 47 and the outer ring 31, and at this time, the push-moving plate 18 blocks the slide guide groove 21 to prevent the ball 19 from rolling into the slide guide groove 21 again, and after the assembly is completed, the air pump 15 Inhales air from the ventilation holes 14 and the expansion and contraction space 13, thereby contracting the expansion and contraction air pipe 17 and preventing the balls 19 from rolling into the slide guide groove 21 again when assembling.

The large motor 62 is started, whereby the worm 61 is rotationally interlocked by the long shaft 60, the worm wheel 59 is rotationally interlocked, the slide block 34 is slid rearward by the lateral screw 33, and the inner ring 47 is rearwardly interlocked. The five balls 19 are partitioned by the support frame 46 and each enter into the five arc grooves 51, and at this time, the electromagnetic spring 65 is energized and the small motor 35 is connected in the opposite direction. The slide gear 64 and the drive gear 63 mesh with each other, and at this time, the drive gear 63 rotationally interlocks the slide gear 64, and the large pulley 68 is rotationally interlocked by the arm shaft 67, and further, the transmission belt 30 The driven pulley 28 is rotationally interlocked by the vertical screw 12, the elevating block 26 is rotationally interlocked by the vertical screw 12, and the outer ring 31 is further ascending and interlocked. Further, the elevating screw 40 raises and interlocks the spline shaft 50, and further raises and interlocks the inner ring 47 and the outer ring 31 in synchronization. At this time, the ball 19 does not fall from between the outer ring 31 and the inner ring 47, and the slide block 34 rearward. When sliding to the limit position on the side, the slide shaft 41 just meshes with the meshing gear 38, and at this time, the electromagnetic spring 65 is cut off and the large motor 62 is stopped. At this time, the meshing gear 38 rotates and interlocks the slide shaft 41. Further, the spline shaft 50 and the elevating screw 40 are rotationally interlocked in synchronization. At this time, the spline shaft 50 does not rise, the inner ring 47 and the outer ring 31 do not rise, and the spline shaft 50 assembles the inner ring 47. The rotation is interlocked in 32, and at this time, the rotation speed of the inner ring 47 can be changed by changing the output rotation speed of the small motor 35. At this time, the outer ring 31 cannot rotate, and the quality of the assembled bearing is detected. Do.

The beneficial effect of the present invention is: The present invention can automatically assemble large ball bearings after artificially mounting the outer ring, which is highly efficient and can automatically detect the quality of the bearing as assembled. No human intervention is required in the detection process, avoiding accidental injury to employees.

By the above method, those skilled in the art can make various changes based on the operation mode within the scope of the present invention.
