[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 3 , a ball screw bearing processing detector, comprising: a support frame 1, a mounting seat 2 fixed on the surface of the support frame 1, a top plate 3 connected to the top of the mounting seat 2, a gear plate 4, a driven gear 5, a rotating rod 6, a connecting rod 7, a telescopic rod 8, a chassis 9, a detection rod 10, a driving motor 11, a mounting shaft 12 and a mounting rod 13, and also comprising: the mounting seat 2 is fixedly connected to the surface of the support frame 1, so as to facilitate bearing detection on the surface of the mounting seat 2, and the gear plate 4 is rotatably connected to the surface of the mounting seat 2. Specifically, the bottom end of the gear plate 4 is fixedly connected with the connecting rod 7, and the connecting rod 7 is rotatably arranged inside the mounting seat 2 through a sleeve shaft. Considering the rotation stability of the gear plate 4, the gear plate 4 is driven by a driving component, and the driving component includes a driving motor 11, and the output end of the driving motor 11 is fixedly connected to the bottom end of the connecting rod 7. Through such a setting, the driving motor 11 mobilizes the gear plate 14 through the connecting rod 7 to rotate stably, thereby ensuring the rotation effect of the gear plate 14;

[0023] Furthermore, considering the synchronous detection of multiple groups of bearings, in order to improve the detection efficiency of ball screw bearings, six groups of driven gears 5 are meshed and connected on the outer wall of the gear plate 4, and the six groups of driven gears 5 are arranged equidistantly in a ring on the outer wall of the gear plate 4. Through the meshing arrangement of the six groups of driven gears 5, the gear plate 4 synchronously drives the multiple groups of driven gears 5 to rotate. Considering the rotation stability of the driven gears 5, the driven gears 5 are rotatably connected to the surface of the mounting seat 2. Specifically, a rotating rod 6 is fixedly connected to the bottom end of the driven gear 5, and the bottom end of the rotating rod 6 is installed on the surface of the mounting seat 2 through the mounting shaft 12, so that the driven gear 5 can be accurately rotated on the outer wall of the gear plate 4 through meshing;

[0024] In order to achieve the fixing effect of the driven gear 5 and the bearing, a mounting rod 13 is fixedly installed at the axis center of the surface of each group of driven gears 5, and a cylinder that can be connected to bearings of different inner diameters is arranged on the surface of the mounting rod 13. Specifically, the surface of the mounting rod 13 is arranged in a multi-layer cylindrical step shape. Under the action of cylinders of different diameters, bearings of different inner diameters can be stably sleeved and installed on the outer wall of the mounting rod 13, and the axis center of the cylinder coincides with the axis center of the driven gear 5. Through such an arrangement, the mounting rod 13 is stably installed on the surface of the driven gear 5, which is convenient for the driven gear 5 to drive the bearing to rotate through the mounting rod 13, so that multiple groups of bearings can be synchronously rotated on the outer wall of the gear plate 4 through the mounting rod 13;

[0025] In order to stably detect multiple groups of rotating bearings, a chassis 9 is telescopically arranged above the gear disk 4. Specifically, a telescopic rod 8 is fixedly connected to the bottom end of the top plate 3, and the output end of the telescopic rod 8 is fixedly connected to the chassis 9, so that the telescopic rod 8 drives the chassis 9 to perform telescopic activities, and the axis center of the chassis 9 coincides with the axis center of the gear disk 4, thereby ensuring the accuracy of the lifting and lowering position of the chassis 9. In order to synchronously detect multiple groups of bearings, six groups of detection rods 10 are arranged in a ring on the side wall of the chassis 9. The detection rod 10 is the dial indicator rod. By making the six groups of detection rods 10 correspond to the setting number of the six groups of mounting rods 13, the detection rod 10 can stably detect the bearing on the outer wall of the mounting rod 13 when it descends through the chassis 9, and under the action of the driven gear 5 driving the bearing to rotate through the mounting rod 13, the detection rod 10 can accurately detect the roundness of the bearing, thereby ensuring the stability of the detection and the work efficiency.

[0026] Working principle: When in use, multiple groups of bearings are installed on the outer wall of the mounting rod 13. Under the effect of the stepped outer wall of the mounting rod 13, bearings with different inner diameters are installed on the outer wall of the mounting rod 13. After the bearings are installed on the outer wall of the mounting rod 13, the telescopic rod 8 is energized, so that the chassis 9 drives the detection rod 10 to move downward, so that the chassis 9 drives multiple groups of detection rods 10 to fit and contact with the outer walls of the bearings respectively. When the roundness of multiple groups of bearings is detected, the driving motor 11 is driven to rotate, so that the connecting rod 7 drives the gear plate 4 to rotate. Under the meshing action of the gear plate 4 and the driven gear 5, the driven gear 5 drives the surface bearing to rotate through the mounting rod 13, so that the detection rod 10 can perform accurate roundness detection on the bearing on the outer wall, thereby ensuring the detection efficiency of the bearing.
