[0019] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0020] Please refer to Figure 1 and Figure 3 As shown, a calibration device for a bearing rolling element comprises a workbench 1 and a mounting plate 7, a fixed block 10 is arranged on one side of the upper surface of the workbench 1, track bars 11 are symmetrically arranged on the upper surface of the workbench 1, and movable clamping blocks 12 are slidably mounted on the surfaces of two track bars 11, and a circular arc surface matching the outer diameter of the bearing is provided on the side where the movable clamping block 12 and the fixed block 10 are close to each other, and two distances between the movable clamping blocks 12 and the fixed block 10 are controlled to clamp the bearing to ensure the stability of the outer ring of the bearing during assembly, a vertical plate 2 is vertically fixed to the rear side of the upper surface of the workbench 1, a lifting plate 4 is slidably mounted on the front side of the vertical plate 2, and the front end of the lifting plate 4 is suspended, and a cylinder 3 is fixed on the top of the vertical plate 2, and the cylinder 3 outputs The end is installed on the upper surface of the rear end of the lifting plate 4, and the height of the lifting plate 4 is controlled by the cylinder 3. A docking tube 5 is arranged on the front end of the upper surface of the lifting plate 4, and the mounting plate 7 is placed below the front end of the lifting plate 4. The mounting plate 7 is placed directly above the bearing. A calibration rod 9 is evenly arranged downward with the bearing center as the center at the bottom of the mounting plate 7. A guide arc surface 901 is arranged at the bottom of the calibration rod 9. When the calibration rod 9 is inserted between the inner and outer rings of the bearing, the internal bearing rolling elements can be guided by the guide arc surface 901 so that the rolling elements are placed on both sides of the calibration rod 9, and then the rolling elements are calibrated to facilitate the installation of the retaining frame. The bottom of the calibration rod 9 is inserted between the inner rings of the bearing, and the calibration rod 9 is placed between two adjacent rolling elements.

[0021] Among them, an extension block 8 is arranged at the top center of the mounting disk 7, and the extension block 8 is adapted to the internal size of the docking sleeve 5. A locking bolt 6 is screwed on one side of the docking sleeve 5, and the mounting disk 7 is tightened and fixed by the locking bolt 6 to fix the mounting disk 7. Different types of bearings require different mounting disks 7. Different numbers of calibration rods 9 are selected according to the gap between the inner and outer rings of the bearing and the number of rolling elements to ensure that multiple rolling elements plus multiple calibration rods 9 can just fill the gap between the inner and outer rings.

[0022] Please refer to Figure 1 and Figure 2 As shown, a protrusion 14 is symmetrically provided on one side of the upper surface of the workbench 1, and an extension rod 15 is symmetrically provided on the side of the movable clamping block 12 away from the fixed block 10. The two extension rods 15 respectively penetrate the two protrusions 14, and a connecting rod 17 is transversely fixed between the ends of the two extension rods 15 away from the movable clamping block 12 to ensure the stability of the movable clamping block 12.

[0023] A handle A13 is vertically fixed on the upper side of the movable clamping block 12 which is away from the fixed block 10 , so as to facilitate the control of the movable clamping block 12 .

[0024] Please refer to Figure 1 and Figure 2 As shown, a spring A16 is sleeved on the surface of the extension rod 15, and the spring A16 is placed between the movable clamping block 12 and the protrusion 14. The elastic force of the spring A16 is used to enable the movable clamping block 12 to move closer to the fixed block 10 to clamp the bearing when no external force is applied.

[0025] Among them, a support platform 18 is arranged on one side of the workbench 1, and a slide bar 19 is vertically slidably installed on the surface of the support platform 18, and a wedge-shaped limit plate 20 is fixed on the top of the slide bar 19, and the wedge-shaped limit plate 20 exceeds the upper surface of the workbench 1, and the positions of the wedge-shaped limit plate 20 and the connecting rod 17 correspond to each other. The side of the wedge-shaped limit plate 20 close to the movable clamping block 12 is arranged as an inclined surface, and a handle B22 is arranged on the outer side of the wedge-shaped limit plate 20. A spring B21 is sleeved on the surface of the slide bar 19, and the top of the spring B21 contacts the lower surface of the wedge-shaped limit plate 20, and the bottom of the spring B21 contacts the upper surface of the support platform 18. When the movable clamping block 12 is controlled to move outward, the connecting rod 17 can be driven to move outward, and the wedge-shaped limit plate 20 can be pressed down by the inclined surface of the wedge-shaped limit plate 20, so that when the movable clamping block 12 moves to the outermost end, it can be limited by the wedge-shaped limit plate 20, so that the movable clamping block 12 remains fixed for loading and unloading.

[0026] The working principle of the utility model is as follows: first, different numbers of calibration rods 9 are installed according to different bearings, and the extension block 8 and the locking bolt 6 are used to achieve fixation. Due to the existence of the spring A16, the movable clamping block 12 always has a force in the direction of the fixed block 10. Similarly, due to the existence of the spring B21, the wedge-shaped limit plate 20 always has an upward force. The movement of the movable clamping block 12 can be controlled by the handle A13 to control the distance between the movable clamping block 12 and the fixed block 10. Due to the existence of the track bar 11, the movable clamping block 12 can only move along the track of the track bar 11. When in use, the movable clamping block 12 is pulled outward to increase the distance between it and the fixed block 10, so that When the connecting rod 17 moves beyond the wedge-shaped limit plate 20, the spring A16 is squeezed and accumulates force, and the connecting rod 17 is limited by the wedge-shaped limit plate 20 and cannot return to its original position. Then the bearing is placed on the inner side of the fixed block 10, and the wedge-shaped limit plate 20 is moved down by the handle B22 so as to no longer limit the connecting rod 17. At this time, the elastic force of the spring A16 is used to make the movable clamp 12 approach the fixed block 10 to clamp and fix the bearing. Then, the lifting plate 4 is controlled to move downward by the cylinder 3, so that multiple calibration rods 9 are inserted between the inner and outer rings of the bearing, and multiple rolling bodies are separated to ensure that the distance between adjacent rolling bodies is consistent. Then, the lifting plate 4 is moved up, and the retaining frame of the rolling body is installed.

[0027] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
