[0004] Combined with the above materials, it can be seen that in the prior art, the bearing assembly machine generally achieves the assembly operation through a manipulator. However, in the actual use process, the operation of the traditional device has poor continuity. For example, the assembly station is single. After processing one, the feeding and discharging operations need to be completed, increasing the workload of personnel and reducing the efficiency. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a full-automatic multi-station rotor bearing assembly machine to solve the problem of low automation degree proposed in the above background technique.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: A full-automatic multi-station rotor bearing assembly machine, including a working platform horizontally placed on the ground. A control panel is fixedly installed on the upper surface of the working platform. Above the working platform, a conveying roller driven by an internal motor is rotatably installed. Above the conveying roller, bearing components to be assembled are placed at equal intervals. And above the working platform, a three-axis operating robotic arm is arranged. At the top of the operating robotic arm, a first mounting block is fixedly installed. And below the first mounting block, a second mounting block is arranged. And an automatic clamping mechanism is arranged on the outer sides of the first mounting block and the second mounting block. The operating robotic arm is rotatably installed above an installation table. And the installation table and an electric slide rail fixedly installed on the upper surface of the working platform form a left-right sliding structure.

[0007] Preferably, the automatic clamping mechanism includes a limit post outside the first mounting block and an extrusion ball outside the second mounting block, and the limit post is connected to the first mounting block through a first cylinder.

[0008] Preferably, the extrusion ball is connected to the second mounting block through a second cylinder, and the extrusion ball is made of soft rubber with a rough surface.

[0009] Preferably, a driving motor is fixedly installed on the lower surface of the first mounting block, and the second mounting block is fixedly connected to the output shaft of the driving motor.

[0012] Preferably, the air inflation balloon and the pressurizing nozzle form a communicating structure through a connecting hose fixedly installed on its front side.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The multi-station rotor bearing full-automatic assembly machine adopts a novel structural design, and the specific content is as follows:

[0014] 1. The bearing components to be assembled are automatically conveyed from left to right by the rotation of the conveying roller. When the bearing components are conveyed to the position of the operating robotic arm, the operating robotic arm cooperates with the automatic clamping mechanism to perform the assembly operation on the bearing components. In this process, the feeding and discharging are realized through automatic conveying, and the continuity of the working process is strong, which improves the overall automation of the device;

[0015] Furthermore, the first cylinder drives the limit post to move, so that the limit post clamps and fixes the bearing outer ring, and the second cylinder drives the extrusion ball to move, and the extrusion ball clamps and fixes the bearing inner ring, so as to realize the assembly operation between the two;

[0016] Even further, after the assembly is completed, the driving motor is started, and the driving motor drives the second mounting block to rotate. Under the limiting action of the extrusion ball, the bearing inner ring is driven to rotate, so as to test the assembled bearing components.

[0017] 2. The infrared locator is used to locate the specific position of the bearing components conveyed to the position of the operating robotic arm, and then the position of the operating robotic arm is changed by the sliding between the mounting table and the electric slide rail to achieve the purpose of precise positioning;

[0018] Furthermore, during the sliding of the installation platform, the air inflation balloon is squeezed. At this time, the air in the air inflation balloon is ejected from the pressurized nozzle through the connecting hose, and the dust on the surface of the infrared locator is cleaned by using the pressurized air flow to ensure the use effect of the infrared locator.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1: Please refer to Figures 1 - 3, in order to achieve the purpose of automatic assembly in this embodiment, the following technical solutions are provided, and specifically disclosed are: a working platform 1 horizontally placed on the ground, a control panel 101 fixedly installed on the upper surface of the working platform 1, a conveying roller 2 driven by an internal motor rotatably installed above the working platform 1, bearing assemblies 3 to be assembled placed at equal intervals above the conveying roller 2, and a three-axis operating robotic arm 4 arranged above the working platform 1. A first mounting block 5 is fixedly installed at the top of the operating robotic arm 4, a second mounting block 8 is arranged below the first mounting block 5, and an automatic clamping mechanism is arranged outside the first mounting block 5 and the second mounting block 8; the automatic clamping mechanism includes a limiting column 7 outside the first mounting block 5 and an extrusion ball 10 outside the second mounting block 8, and the limiting column 7 is connected to the first mounting block 5 through a first air cylinder 6, the extrusion ball 10 is connected to the second mounting block 8 through a second air cylinder 9, and the extrusion ball 10 is made of soft rubber with a rough surface. A driving motor 11 is fixedly installed on the lower surface of the first mounting block 5, and the second mounting block 8 is fixedly connected to the output shaft of the driving motor 11.

[0028] When using the device, first place the bearing assemblies 3 to be assembled above the conveying roller 2, use the motor inside the working platform 1 to drive the conveying roller 2 to rotate, and convey the bearing assemblies 3 from left to right. When the bearing assemblies 3 are conveyed to the position of the operating robotic arm 4, operate the first mounting block 5 and the second mounting block 8 through the operating robotic arm 4. At this time, the first air cylinder 6 outside the first mounting block 5 drives the limiting column 7 to move, and the bearing outer ring is clamped and fixed by the limiting column 7. At the same time, the second air cylinder 9 drives the extrusion ball 10 to move, and the bearing inner ring is squeezed to the middle position by the extrusion ball 10, so that the bearing outer ring and the bearing inner ring are concentric, thus completing the assembly operation. After the assembly is completed, turn on the driving motor 11, use the driving motor 11 to drive the second mounting block 8 to rotate, and at this time, drive the bearing inner ring to rotate under the action of the extrusion ball 10 to achieve the purpose of testing the assembled bearing. The assembled bearing continues to be conveyed by the conveying roller 2.

[0029] Embodiment Two: Please refer to Figures 4 - 6 , in order to achieve the purpose of automatic positioning and installation in this embodiment, the following technical solutions are provided, and specifically disclosed are: the operating robotic arm 4 is rotatably installed above the installation table 12, and a left-right sliding structure is formed between the installation table 12 and an electric slide rail 15 fixedly installed on the upper surface of the working platform 1.

A pressure nozzle 17 fixedly installed in a groove of the working platform 1 is arranged above the conveying roller 2. An air inflation balloon 16 is fixedly installed between the left and right installation tables 12, and the air inflation balloon 16 and the pressure nozzle 17 form a communication structure through a connecting hose 18 fixedly installed on its front side.

[0030] When the bearing assembly 3 moves to the position of the operating robotic arm 4, the infrared locator 14 is used to locate the precise position of the bearing assembly 3. Then, the mounting table 12 slides relative to the electric slide rail 15, so that the operating robotic arm 4 is moved to the position precisely corresponding to the bearing assembly 3 by means of the mounting table 12. The movement of the mounting table 12 squeezes the air injection balloon 16. When the air injection balloon 16 is squeezed, the air inside it is ejected from the pressurized nozzle 17 through the connecting hose 18. The ejected pressurized air flow is used to clean the dust on the surface of the infrared locator 14 to ensure the subsequent use effect of the infrared locator 14.
