[0002] Bearings are mechanical components used to support rotating shafts, reduce frictional resistance, and ensure rotational accuracy. For high-precision bearings such as P4 and P5, the machining of their inner rings and inner spherical surfaces requires extremely high shape and positional tolerances and surface finishes. This has driven the development of CNC grinding machines and special-purpose composite machining tools.

[0003] For example, in a class of prior art represented by application number CN202420052822.3, the main structure includes a machine base, on which a processing table is mounted. The processing table is rotatably mounted on the machine base via a rotating rod. The rotating rod is driven to rotate by a rotary drive mechanism. The rotary drive mechanism includes a first worm gear fixed on the rotating rod, and a rotating rod rotatably mounted on the bottom of the machine base via a bearing on one side of the first worm gear. A first worm gear, which is connected to the first worm gear through a transmission, is fixed on the rotating rod. The rotating rod is driven to rotate by the rotary drive mechanism. Fixed seats are installed at both ends of the machine base, and clamping and fixing components are provided on the fixed seats for limiting and fixing the bearing seat. This utility model relates to the field of bearing seat processing technology. This rotary worktable for bearing seat processing solves the problems of existing bearing seat processing worktables being inconvenient to adjust the rotation position, increasing the operational risks of manual operation, and causing low work efficiency and limited use.

Both the first limiting block 42 and the second limiting block 43 are slidably mounted on the second sliding groove 33. The monitoring device 06 includes a position sensor 61, which is installed on the side of the turntable 32. The processing device 07 includes a bracket 71, a third motor 73, a second lead screw 74, an adjusting block 75, and a cutting tool 76. The bracket 71 is installed on the top of the base 11 and has a sliding groove 72. The third motor 73 is installed on the side of the bracket 71 and its output end is rotatably connected to the input end of the second lead screw 74.

Then, the activation of the dual-axis cylinder 41 retracts the two sets of output shafts, causing limiting blocks 42 and 43 to move in opposite directions on the sliding groove 33. During this process, buffer pads 51 and 52 work together to cushion the bearing housing during clamping. Finally, the activation of the motor 21 rotates the lead screw 22, orienting the moving block 23 on the sliding groove 12. The movement is initiated by observing the positions of the bearing housing and the cutting tool 76 through the position sensor 61. Once the appropriate position is reached, motor 1 21 is stopped. Then, motor 2 31 is started, causing its output shaft and turntable 32 to rotate, which in turn rotates the bearing housing. Motor 3 73 is started, causing lead screw 2 74 to rotate, which moves the adjusting block 75 directionally on motor 3 73. The cutting tool 76 then performs turning on the bearing housing. Simultaneously, motor 1 21 is started, causing the bearing housing to be fed, thus performing turning on the bearing housing until the machining is complete.
