[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Common bearings are mainly assembled with inner rings, outer rings, and roller bodies. During assembly, the inner ring is installed to one side of the inner outer ring, and a certain number of rolling elements are placed between the two, and the rolling elements are evenly distributed through rotation.

[0003] At present, during the processing of bearings, it is necessary to use a clamp to clamp the bearings, so as to open a through groove between the inner circle and the outer ring and place the ball inside it. The existing technology uses an air cylinder to drive the clamp to clamp the outer ring of the bearing. This operation is convenient and fast, but the single movement distance of the cylinder is the same, which leads to the need to readjust the stroke of the cylinder when replacing the outer ring of the bearing of different sizes. The operation is cumbersome. By only fixing the outer ring, it is inevitable that shaking will occur during processing, affecting the processing efficiency.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0024] An outer ring fixing fixture comprises an operating table 1, four corners of the bottom of the operating table 1 are equipped with columns 2, a workbench 3 is installed on the top of the operating table 1, and a clamping assembly 4 is installed in the middle of the top of the workbench 3;

[0025] The clamping assembly 4 is used to clamp and fix the inner ring of the bearing.

[0026] For further information, see Figure 1 and Figure 2In this embodiment, the clamping assembly 4 includes a triangular block 401, an extrusion block 402, a connecting shaft 403, a linkage plate 404 and a control rod 405. The triangular block 401 is installed in the middle of the top of the workbench 3, the extrusion block 402 is installed on the outside of the triangular block 401, the connecting shaft 403 is installed on the bottom of the triangular block 401, and the connecting shaft 403 extends to the inside of the workbench 3, the linkage plate 404 is installed on the outside of the connecting shaft 403, and the control rod 405 is installed on the outside of the linkage plate 404, and the control rod 405 extends to the outside of the workbench 3. When processing the bearing, it is necessary to clamp and fix the bearing, open a through groove between the inner ring and the outer ring of the bearing, and place a ball inside the through groove. By placing the bearing on the top of the workbench 3, by toggling the control lever 405, the control lever 405 drives the linkage plate 404 to rotate, and at the same time drives the connecting shaft 403 to rotate, so that the top of the triangular block 401 workbench 3 rotates, so that the protruding part of the triangular block 401 squeezes the extrusion block 402, so that the extrusion block 402 squeezes the inner ring of the bearing, and the bearing is fixed.

[0027] Among them, see Figure 1 and Figure 2 In this embodiment, a groove 5 is provided on the right side of the workbench 3, a U-shaped groove is provided inside the groove 5, and a slide groove 6 is symmetrically provided on the top of the workbench 3. The connection between the connecting shaft 403 and the linkage plate 404 is a rotational connection. A connecting frame is installed on the side of the linkage plate 404 away from the connecting shaft 403. The control rod 405 is connected to the connecting shaft 403 through the connecting frame. When the fixation needs to be released, the control rod 405 is pushed in the reverse direction so that the control rod 405 leaves the U-shaped groove, thereby pushing the control rod 405 downward, so that the control rod 405 is folded downward, so that the control rod 405 is retracted to the inside of the groove 5, so that when idle, the control rod 405 will not extend out and occupy space.

[0028] Second, see Figure 1 and Figure 2 In this embodiment, a rotating column is installed at the eccentric part of the extrusion block 402, a winding belt is installed between the rotating column and the extrusion block 402, a spring 406 is installed on the right side of the linkage plate 404, hooks are installed at both ends of the spring 406, and a stabilizing plate is installed at the end of the spring 406 away from the linkage plate 404. When the bearing needs to be fixed, the control rod 405 is pushed down by toggling the control rod 405, so that the control rod 405 moves to the inside of the U-shaped groove, driving the spring 406 to extend. When it is not necessary to fix, after toggling the control rod 405, the spring 406 is stretched and retracted to store energy, so as to realize the automatic reset of the control rod 405.

[0029] Furthermore, please see Figure 1 and Figure 3In this embodiment, a fixed frame is installed on the front and rear sides of the workbench 3, and a double-headed screw rod 7 and a sliding rod 8 are installed inside the fixed frame respectively. A sliding plate 9 is installed outside the double-headed screw rod 7 and the sliding rod 8. By rotating the double-headed screw rod 7, a threaded reaction between the sliding plate 9 and the double-headed screw rod 7 is achieved. The sliding plate 9 is limited by the sliding rod 8 again to achieve the movement of the sliding plate 9 on the double-headed screw rod 7.

[0030] For further information, see Figure 1 and Figure 3 In this embodiment, an extension rod is installed on the top of the sliding plate 9 and inside the slide groove 6, and a splint 10 is installed on the top of the extension rod. Suction cups 11 are installed on the sides of the splints 10 that are close to each other. By bringing the sliding plates 9 closer to each other, the splints 10 are brought closer to each other, so that the splint 10 fixes the outer ring of the bearing, and the suction cups 11 adsorb the outer ring of the bearing, thereby fixing the outside of the bearing.

[0031] For further information, see Figure 1 and Figure 3 In this embodiment, a square groove is opened in the middle of the clamping plate 10, and a threaded rod 12 is installed inside the square groove. The threaded rod 12 extends to the top of the clamping plate 10, and a pressure plate 13 is installed outside the threaded rod 12 and inside the square groove. When the outer ring and the inner ring of the bearing are fixed, the threaded rod 12 is rotated to press the pressure plate 13 downward, thereby fixing the top of the bearing, and further achieving stability during fixation.

[0032] In this embodiment, the implementation scenario is specifically as follows: when the bearing needs to be processed, the bearing needs to be clamped and fixed, a through groove is opened between the inner ring and the outer ring of the bearing, and a ball is placed inside the through groove. By placing the bearing on the top of the workbench 3, the control rod 405 is toggled, so that the control rod 405 drives the linkage plate 404 to rotate, and at the same time drives the connecting shaft 403 to rotate, so that the top of the triangular block 401 workbench 3 rotates, and the control rod 405 is pressed down, so that the control rod 405 moves to the inside of the U-shaped groove, driving the spring 406 to extend, so that the protrusion of the triangular block 401 Part of the extrusion block 402 is extruded, so that the extrusion block 402 squeezes the inner ring of the bearing and fixes the bearing. By rotating the double-headed screw 7, the sliding plate 9 and the double-headed screw 7 have a threaded reaction. The sliding plate 9 is limited by the sliding rod 8 again to move the sliding plate 9 on the double-headed screw 7, so that the clamping plates 10 are close to each other, so that the clamping plates 10 fix the outer ring of the bearing, so that the suction cup 11 adsorbs the outer ring of the bearing, and by rotating the threaded rod 12, the pressure plate 13 is pressed down, so that the top of the bearing is fixed, and the stability during fixation is further achieved.
