The end of the output shaft of the servo motor 3-3 is fixedly connected to the jacking block 3-4. A through hole is provided through the main body 1 of the bushing centering machine frame. The jacking block 3-4 is arranged directly below the through hole. When the bushing body 6 moves to the through hole, it will fall onto the jacking block 3-4. Starting the servo motor 3-3 to rotate drives the bushing body 6 to rotate, enabling the accurate positioning of the keyway direction.
[0024] A precision sensor 4 is fixedly connected to the top of the bushing centering machine frame body 1, which can accurately locate the keyway direction. An L-shaped plate is fixedly connected to the top of the bushing centering machine frame body 1, and the precision sensor 4 is arranged on and fixedly connected to the L-shaped plate. A transformable die 5 is installed on the bushing centering machine frame body 1. The transformable die 5 includes a feeding cylinder 5-1, a first slider 5-2, a first guide rail 5-3, and a pushing plate 5-4. The feeding cylinder 5-1 is arranged on and fixedly connected to the top of the bushing centering machine frame body 1. The output end of the feeding cylinder 5-1 is fixedly connected to the first slider 5-2. The first guide rail 5-3 is arranged on and fixedly connected to the top of the bushing centering machine frame body 1. The first slider 5-2 is sleeved on the outer wall of the first guide rail 5-3 and is slidably connected thereto. The side wall of the first slider 5-2 is fixedly connected to the pushing plate 5-4. An arc-shaped groove is formed in the pushing plate 5-4. When the bushing body 6 is located below the through hole, it is moved to the through hole position through the pushing plate 5-4. At this time, the bushing body 6 is then lifted and inserted into the arc-shaped groove to complete the movement of the bushing body 6. Finally, it is grasped by a manipulator.
[0025] A plurality of bushing bodies 6 are arranged on the bushing centering machine frame body 1. The bushing bodies 6 flow from the vibrating disk into the space between two variable guide blocks 2 and are arranged in sequence between the two variable guide blocks 2. The bushing bodies 6 are arranged between the two variable guide blocks 2. A pushing cylinder 7 is fixedly connected to the top of the bushing centering machine frame body 1. The output end of the pushing cylinder 7 is fixedly connected to a second slider 8. A second guide rail 9 is fixedly connected to the top of the bushing centering machine frame body 1. The second slider 8 is sleeved on the second guide rail 9 and is slidably connected thereto. The second slider 8 is fixedly connected to a pushing block 10. A fixing plate 11 is fixedly connected to the top of the bushing centering machine frame body 1.
[0026] In the present utility model, the working steps are as follows: S1, the bushing bodies 6 flow from the vibrating disk into the space between two variable guide blocks 2 and are arranged in sequence between the two variable guide blocks 2;
[0027] S2, start the pushing cylinder 7 to drive the second slider 8 and the pushing block 10 to move, and push a bushing body 6 into the through hole;
[0028] S3, drive the lifting plate 3-2, the servo motor 3-3, and the jacking block 3-4 to move upward through the lifting cylinder 3-1 to lift the bushing body 6 to the detection position of the precision sensor 4;
[0029] S4, start the servo motor 3-3 to drive the jacking block 3-4 and the bushing body 6 to rotate and determine the position (alignment of the bushing keyway);
[0030] S5. Start the lifting cylinder 3-1 to drive the lifting plate 3-2, the servo motor 3-3, the jacking block 3-4 and the bushing body 6 to fall back into the through port. Start the feeding cylinder 5-1 to drive the first slider 5-2 and the pushing plate 5-4 to move to the position of the through port. Start the lifting cylinder 3-1 to drive the lifting plate 3-2, the servo motor 3-3, the jacking block 3-4 and the bushing body 6 to move upward beyond the through port and the arc-shaped groove. Drive the first slider 5-2, the pushing plate 5-4 and the positioned bushing into the manipulator by the feeding cylinder 5-1 to grab the bushing.
[0031] By setting the cooperating guide blocks with variable spacing, the adjusting mechanism and the precision sensors, the utility model solves the problems that the prior art can only be applicable to one kind of bushing and cannot position the keyway direction for the bushing with a keyway.
