The axial limiting component includes a second threaded rod 11, a limiting member 12, and a first clamping block 13. The first fixing rod 10 is of a hollow structure and an installation groove is formed at the end close to the rotating plate 6.

[0018] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, which are as follows:

[0019] In the present utility model, the motor 3 is connected to an external electronic control system through a wire. The above devices and connection methods are all prior arts and will not be elaborated here.

[0020] According to the attached drawings of the specification Figures 1-3It can be known that when the utility model is in use, firstly, a plurality of bearing workpieces are sleeved on the outer sides of a plurality of first fixing rods 10 in a plurality of fixing assemblies. The number of first fixing rods 10 in each fixing assembly is preferably 4. Secondly, a plurality of first threaded rods 7 threadedly connected to the threaded holes 6-2 on the rotating plate 6 are respectively screwed, so that the first threaded rods 7 drive the protrusions 8 provided at their ends to move in a direction close to the first fixing rods 10. When the protrusions 8 move, the plurality of sliding blocks 9 slidably connected thereto move in a direction away from the protrusions 8. The protrusions 8 drive the plurality of first The fixing rod 10 moves outward, so that the multiple first fixing rods 10 expand and fix the inner ring of the bearing workpiece (internal expansion type). When the first fixing rod 10 moves, the spring 16 in the corresponding slide groove 6-3 contracts, and the connected limiting rod 15 moves into the limiting cylinder 14. The limiting rod 15 and the limiting cylinder 14 can ensure the linear movement of the first fixing rod 10 and prevent it from escaping from the slide groove 6-3. The bearing workpiece is then axially limited by the axial limiting assembly. Again, a drilling device is used to drill a hole in one of the bearing workpieces. When one of the shafts is After the bearing workpiece is processed, the motor 3 arranged on the vertical plate 2 is started, and the motor 3 drives the rotating shaft 4 connected to the output end to rotate, and the rotating shaft 4 drives the rotating plate 6 to rotate in the ring body 5, so that another bearing workpiece to be processed is rotated to the drilling equipment for processing. During the processing, the personnel reversely screw the first threaded rod 7 at the bearing workpiece after the processing, and then the axial limit assembly releases the axial limit of the bearing workpiece, and the first threaded rod 7 drives the protrusion 8 to move in the direction away from the first fixing rod 10. Under the elastic force of the spring 16, multiple first fixing rods 10 are gathered toward the center. After the personnel removes the bearing workpiece, they fix the new workpiece to be processed, and the whole processing flow is completed by repeating the operation. The utility model screws the first threaded rod 7 so that the first threaded rod 7 drives multiple first fixing rods 10 to move outward to open and fix the bearing workpiece, and the axial limit assembly limits the axial position of the bearing workpiece. When drilling a bearing workpiece is completed, when processing another bearing workpiece, the processed workpiece can be disassembled and the new workpiece can be fixed, thereby saving the time for fixing and disassembling the bearing workpiece and increasing the efficiency of the overall drilling processing.

[0021] There is a possible implementation. When the axial workpiece is axially limited, the second threaded rod 11 arranged in the first fixed rod 10 is screwed and rotated. The second threaded rod 11 drives the threaded sleeve 12-1 connected to the first fixed rod 10 to move. The threaded sleeve 12-1 drives a pair of second fixed rods 12-2 to slide in the through groove 10-1. The protruding part of the second fixed rod 12-2 abuts against the bearing workpiece for limiting. The first clamping block 13 arranged at the end of the second threaded rod 11 can prevent the second threaded rod 11 from moving axially relative to the first fixed rod 10.

[0022] One possible implementation is that a second clamping block 15-1 is provided at the end of each limiting rod 15 located inside the limiting cylinder 14, and the second clamping block 15-1 can abut against the opening of the limiting cylinder 14 to prevent the limiting rod 15 from detaching from the limiting cylinder 14.

[0023] One possible implementation is that a limiting groove 5-1 is formed on the ring body 5, and a limiting ring 6-4 is provided on the rotating plate 6. The limiting ring 6-4 is rotatably arranged in the limiting groove 5-1, and the limiting groove 5-1 limits the limiting ring 6-4 to prevent the rotating plate 6 from shifting during rotation.
