Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1-5 As shown, an automatic pin angle detection device includes a worktable 11, a feeding station 12, a material handling mechanism 23, an eccentric bearing support mechanism 20, an eccentric shaft angle adjustment device 21, and a discharge mechanism 1. The feeding station 12, the material handling mechanism 23, the eccentric bearing support mechanism 20, the eccentric shaft angle adjustment device 21, and the discharge mechanism 1 are all located on the worktable 11. The eccentric bearing support mechanism 20 is located in the middle of the worktable 11 and below the eccentric shaft angle adjustment device 21. The material handling mechanism 23 is located next to the feeding station 12, and the discharge mechanism 1 is located at the end of the eccentric bearing support mechanism 20.

[0024] In this embodiment, the material handling mechanism 23 includes a material handling robot and a robot drive device 14 for driving the material handling robot. The robot drive device 14 is a four-axis robot arm, which includes three rotational degrees of freedom and one lifting degree of freedom located at the end of the robot arm. The material handling robot is located at the output end of the robot drive device 14. The four-axis robot arm is an execution mechanism that integrates precise and flexible movements in the prior art, and can accurately grip the eccentric shaft 5 on the feeding station 12 and place it into the eccentric bearing support mechanism 20.

[0025] In this embodiment, the material handling robot includes a clamping cylinder 15 and a clamping robot 13 located at the output end of the clamping cylinder 15. The cylinder body of the clamping cylinder 15 is connected to the output end of the robot drive device 14, and is driven by the robot drive device 14 to perform displacement on the horizontal plane and lifting on the vertical plane.

[0026] like Figure 5 As shown in this embodiment, the feeding station 12 is provided with a material box 25 for accommodating eccentric shafts 5. The material box 25 has material placement positions arranged in an array, and the eccentric shafts 5 to be processed are placed in the material placement positions. In production, the eccentric shafts 5 in the material box 25 are placed by the previous process. The angles and directions of the eccentric shafts 5 are inconsistent, and they cannot be directly used for the automated production of the next process. Therefore, this utility model is used for processing.

[0027] In this embodiment, the eccentric bearing support mechanism 20 includes a sliding track 9, a sliding seat 6, an eccentric bearing support 7, and a sliding push mechanism 22. The sliding track 9 is arranged along the Y-axis direction. The sliding seat 6 is slidably mounted on the sliding track 9. The cylinder of the sliding push mechanism 22 is fixed relative to the worktable 11. The output end of the sliding push mechanism 22 pushes the sliding seat 6 to slide along the sliding track 9. The eccentric bearing support 7 is mounted on the sliding seat 6. The eccentric shaft angle adjustment device 21 is located in the middle of the sliding track 9. The specific form of the sliding push mechanism 22 is not limited; it can be an electric push cylinder, a lead screw, a gear rack type, or a linear motor type, as long as it can push the sliding seat 6 to translate along the direction of the sliding track 9.

[0028] In this embodiment, the eccentric bearing carrier 7 is provided with a receiving position for accommodating the eccentric shaft 5, and the bottom of the receiving position is provided with an oil drain hole 26. An eccentric shaft positioning sensor 8 is arranged in the middle and lower part of the eccentric bearing carrier 7.

[0029] like Figure 3 As shown, in this embodiment, the eccentric shaft angle adjustment device 21 includes a column 24, a lifting seat 18 located in front of the column 24, and a lifting drive mechanism 16 for driving the lifting seat 18 to move up and down. The lifting seat 18 is provided with an eccentric shaft angle adjustment motor 17. The output end of the eccentric shaft angle adjustment motor 17 extends downward through the lifting seat 18, and the output end of the eccentric shaft angle adjustment motor 17 is provided with an adjustment sleeve 19.

[0030] In this embodiment, the adjusting sleeve 19 is provided with a concave shaft hole for receiving the upper end of the eccentric shaft 5, and the upper bottom surface of the shaft hole is provided with an eccentric hole 27, which receives an eccentric pin located at the upper end of the eccentric shaft 5 to be processed.

[0031] In this embodiment, the workbench 11 is also provided with an oil tank 10, which is close to the feeding station 12 or the eccentric bearing support mechanism 20. The oil tank 10 is used for oiling.

[0032] like Figure 4 As shown, in this embodiment, the discharge mechanism 1 includes a discharge robot 4, an X-axis displacement drive mechanism 2 that drives the discharge robot 4 to move along the X-axis, and a Z-axis displacement drive mechanism 3 that moves up and down along the Z-axis. The specific forms of the X-axis displacement drive mechanism 2 and the Z-axis displacement drive mechanism 3 are not limited; they can be electric push cylinders, lead screw guides, gear racks, or linear motors, as long as they can drive the discharge robot 4 to move along the X-axis and Z-axis.

[0033] Specifically, the working principle of this utility model is as follows:

[0034] In the production process of this utility model, the material box 25 is placed on the feeding station 12. In the eccentric bearing carrier mechanism 20, the sliding seat 6 is located at one end near the feeding station 12. The picking mechanism 23 picks up the eccentric shaft 5 from the material box 25 and coats it with oil in the oil tank 10. The oiling serves to lubricate the eccentric shaft 5 when it is subsequently installed into the rotor assembly. After oiling, the picking mechanism 23 places the eccentric shaft 5 into the eccentric bearing carrier 7. At this time, the direction of the eccentric pin on the eccentric shaft 5 is random, and because the eccentric shaft 5 is coated with oil, the gap between the inner cavity of the eccentric bearing carrier 7 and the eccentric shaft 5 is small, so the eccentric shaft 5 is not fully inserted. Then, the sliding seat 6 is pushed by the sliding pushing mechanism 22 to below the eccentric shaft angle adjustment mechanism 21. The lifting drive mechanism 16 drives the alignment sleeve 19 downward, and the eccentric shaft angle alignment motor 17 rotates. In this case, the eccentric shaft 5 will be sleeved by the alignment sleeve 19, and as it rotates, the eccentric pin on the eccentric shaft 5 enters the eccentric hole 27. The stopping angle of the eccentric shaft angle alignment motor 17 is fixed, so that the eccentric pins of the eccentric shaft 5 stop at the limited angle. Finally, the lifting drive mechanism 16 drives the lifting seat 18 downward, pushing the eccentric pins down to the bottom. The oil drain hole 26 of the eccentric bearing carrier 7 is connected to the oil drain pipe, which drains the excess oil in the eccentric bearing carrier 7 from below, and the eccentric shaft position sensor 8 (infrared sensor) senses that the eccentric shaft 5 has descended to the bottom. At this point, the eccentric shaft 5 has completed its angle adjustment action, the lifting seat 18 moves upward, the sliding seat 6 moves to the end of the sliding track 9, and the robotic arm of the discharge mechanism 1 picks up the eccentric shaft 5 and outputs it to the next process. At this time, the eccentric pins on the output eccentric shaft 5 have the same angle and can be directly used for the installation work of the next process without repeated adjustments.
