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.

[0025] See also Figure 1 A three-in-one bearing unit assembly tooling includes a workbench 1, wherein track grooves 12 are symmetrically arranged on the upper part of the workbench 1, and a table foot 11 is arranged at the lower part of the track groove 12. A motor and a control system are arranged in the table foot 11. A fixing component 2 is arranged at the upper geometric center position of the workbench 1, and a connecting rod 3 facing the fixing component 2 is arranged in the track groove 12. A slider matched with the track groove 12 is arranged at one end of the connecting rod 3, and an arc-shaped push plate 4 with a concave surface facing the fixing component 2 is arranged at the other end of the connecting rod 3. The control system can drive the motor to drive the slider to make regular movements in the track groove 12. These realize the control of the slider by adjusting the motor through the control system. The programmed movement of the slider drives the connecting rod 3 and the push plate 4 to move, so that the subsequent force on the outer ring of the bearing 6 can be applied, that is, the outer ring of the bearing 6 can be moved in a directional manner to put the ball into the assembly action.

[0026] See also Figure 2 The fixing assembly 2 includes a central column 21 with a cavity and at least two support members 22. The central column 21 is perpendicular to the workbench 1. The support members 22 are arranged on the side walls of the central column 21 and can be movably extended and retracted on the side walls. When the subsequent air pump 5 is not used, the support members 22 can be subjected to force on the central column 21 and extend and retract inward and outward.

[0027] See also Figure 3 The head of the support member 22 is an arc-shaped support plate 221 with the convex surface facing outward, and the tail is arranged inside the central column 21 and has a limit plate 222. An air pump 5 is arranged at the lower geometric center of the workbench 1, and the air outlet 23 of the air pump 5 is vertically arranged in the cavity of the central column 21. After the air pump 5 pumps out the gas, the gas is ejected from the air outlet 23.

[0028] See also Figure 4 At least one support column 231 is vertically arranged on the upper part of the gas outlet 23, and a baffle 232 for changing the direction of the pumped gas is arranged on the upper part of the support column 231, so that the gas can be ejected in the horizontal direction and hit the limit plate 222 to exert thrust on it, so that the limit plate 222 is pushed out to squeeze the inner ring of the bearing 6.

[0029] See also Figure 5 , which is a schematic diagram showing that after the air pump 5 pumps air into the center column 21, the baffle 232 moves outward to support the inner ring of the bearing 6.

[0030] See also Figure 6 The bearing 6 parts to be processed are placed on the fixed component 2, the inner ring of the bearing 6 is sleeved on the periphery of the fixed component 2, and the outer ring is sleeved on the periphery of the inner ring. The diameter of the support member 22 when fully protruding is greater than the diameter of the inner ring of the bearing 6.

[0031] Working principle: First, the upper part of the workbench of the tooling is symmetrically provided with a track groove 12, and the lower part of the track groove 12 is equipped with a table foot 11, a motor and a control system. A fixed component 2 is provided at the geometric center position of the upper part of the workbench 1, including a center column 21 and a support member 22, and then the inner ring of the bearing 6 is sleeved on the support member 22, and it has not been fixed at this time; the connecting rod 3 is located in the track groove 12 and is equipped with a slider. The control system drives the slider to make regular movements in the track groove 12 through a motor. One end of the connecting rod 3 is equipped with an arc-shaped push plate 4 with a concave surface facing the fixed component 2, and the other end is equipped with a slider adapted to the track groove 12. Then the outer ring of the bearing 6 is sleeved outside the inner ring of the bearing 6, and then the push plate 4 can be moved by moving the slider to act on the outer ring and move its position relative to the inner ring; the center column 21 of the fixed component 2 is perpendicular to the workbench 1, and the support member 22 is arranged around its side wall and can be movable and retractable. The head of the support member 22 is an arc-shaped support plate 221 with a convex surface facing outward, and a limit plate 222 is provided at the tail. These components cooperate with the air pump 5 to make the support plate 221 firmly press against the inner ring to fix it; the air pump 5 is located at the lower part of the workbench 1, and the air outlet 23 is set in the cavity of the central column 21. The setting of the support column 231 and the baffle 232 changes the airflow direction of the air pump 5 to ensure that the gas pushes the support plate 221 to expand outward and firmly supports the inner ring of the bearing; after the inner ring is fixed, the slider performs a programmatic operation to make the push plate 4 press against the outer ring and move it to make room for the ball, and then move it back to achieve the assembly of the ball.

[0032] In summary, the trinity bearing unit assembly tooling achieves a series of coordinated effects by integrating the precise workbench 1 structure, track groove 12, fixing component 2, motor and control system and other elements. The workbench 1 of the tooling is designed with symmetrically arranged track grooves 12, and a fixing component 2 is provided at the upper geometric center, including a center column 21 and a support member 22. The center column 21 is perpendicular to the workbench 1, and the support member 22 can be moved and retracted on the side wall, providing stable support for the inner ring of the bearing 6; the connecting rod 3, as one of the key components, is placed in the track groove 12, and one end of it has an arc-shaped push plate 4 aligned with the fixing component 2. By driving the motor through the control system, the slider moves regularly in the track groove 12, providing stable support for the outer ring of the bearing 6, and the relative position of the movable outer ring can be controlled, so that the ball bearing can be assembled inside; the bearing 6 parts in the fixed component 2 are placed on the fixed component 2, the inner ring is set on the outer periphery of the fixed component 2, and the outer ring is set on the outer periphery of the inner ring, which further ensures the accuracy and stability of the assembly; in addition, the air pump 5 is located at the lower part of the workbench, and its air outlet 23 is set in the cavity of the central column 21, providing a supporting power source for the bearing 6. The setting of the support column 231 and the baffle 232 changes the air flow direction of the air pump, so that the gas pushes the support plate 221 to expand outward to resist the inner ring of the bearing 6, ensuring the smooth progress of the assembly process; thereby achieving the effects of improving assembly accuracy and consistency, ensuring stable product quality, improving assembly efficiency, and preventing personnel fatigue.
