[0023] When chamfering operation is performed, the hydraulic cylinder 3 drives the fixed frame 4, the motor 5, and the chamfering head 6 to move downward synchronously, the fixed frame 4 drives the two lifting plates 8 to move downward synchronously, the connecting tube 22 and the push rod 21 apply thrust to the movable plate 16, and drive the positioning head 17 to move forward until the positioning head 17 is pressed tightly against the positioning seat 10, thereby locking and fixing the flip table 12. At this time, the spring 23 is in a compressed state, and the motor 5 drives the chamfering head 6 to rotate, which is convenient for chamfering the inner hole of the valve rocker arm.

[0024] When one side is chamfered, the hydraulic cylinder 3 drives the fixed frame 4, the motor 1 5, and the chamfering head 6 to move upward synchronously, so that the positioning head 17 is separated from the positioning seat 10, and the turning table 12 is loosened. The motor 2 15 drives the turning table 12 to rotate, so as to turn the workpiece over, which is convenient for chamfering the other side. The operation is flexible and convenient, and the processing efficiency is high.

[0025] The positioning mechanism includes an arc-shaped baffle 11, a connecting seat 25, a cylinder 26, and a pressing plate 27. The arc-shaped baffle 11 matches the arc surface of the workpiece, the connecting seat 25 is fixed to the turning table 12, the cylinder 26 is connected to the connecting seat 25, and the power output end of the cylinder 26 is connected to the pressing plate 27. After the workpiece is placed on the turning table 12, its arc surface is attached to the arc-shaped baffle 11, and the cylinder 26 drives the pressing plate 27 to move forward, so that the pressing plate 27 is pressed against the workpiece, thereby realizing the locking and fixing of the workpiece, improving the stability of the connection between the workpiece and the turning table 12, and facilitating the subsequent chamfering operation.

[0026] The arc-shaped baffle plate 11 is fixed to the turning platform 12 , and the arc-shaped baffle plate 11 and the pressing plate 27 are arranged opposite to each other.

[0027] The second motor 15 is connected to the end of the workbench 1, and the power output end of the second motor 15 is connected to a rotating shaft 19, the end of the rotating shaft 19 is connected to one side of the flip table 12, and the rotating shaft 19 is rotatably connected to the workbench 1, and the other side of the flip table 12 is connected to the workbench 1, so that the flip table 12 rotates stably.

[0028] The locking mechanism includes a lifting plate 8, a guide column 9, a moving plate 16, a positioning head 17, a push rod 21, a connecting tube 22, a spring 23, and a sliding block 24.

Both ends of the spring 23 are connected to the sliding block 24 and the connecting tube 22. The end of the connecting tube 22 is hinged to the lifting plate 8. When chamfering, the fixed frame 4 drives the two lifting plates 8 to move downward synchronously. The lifting plate 8 applies a downward thrust to the connecting tube 22, and the push rod 21 pushes the movable plate 16 forward. The angle between the connecting tube 22 and the lifting plate 8 gradually increases, and the movable plate 16 pushes the positioning head 17 forward. The positioning head 17 is pressed against the positioning seat 10 to lock and fix the flip table 12 to avoid shaking during chamfering and affecting the chamfering accuracy. At this time, the spring 23 is in a compressed state, the fixed frame 4 can move further downward, the chamfering head 6 moves downward synchronously, and the spring 23 is further compressed to achieve control of the chamfering depth of the inner hole.

[0029] When one side is chamfered, the fixed frame 4 and the chamfering head 6 move up synchronously, the lifting plate 8 also moves up, the angle between the lifting plate 8 and the connecting tube 22 gradually decreases, and the push rod 21 pulls the moving plate 16 back to separate the positioning head 17 from the positioning seat 10, thereby loosening the turning table 12. Then the motor 2 15 drives the rotating shaft 19 to rotate, so as to turn the workpiece over, so that the other side of the workpiece faces upward, and the chamfering operation is performed.

[0030] The top and bottom of the turning table 12 are connected with a positioning seat 10, and the side of the positioning seat 10 is provided with a positioning groove 18, which matches the positioning head 17.

[0034] The workbench 1 is provided with a rectangular hole 14 matching the turning table 12 , and the rectangular hole 14 maintains a certain distance from the four outer side surfaces of the turning table 12 to facilitate the turning of the turning table 12 .

[0035] Working principle: Place the valve rocker arm on the turning table 12, and the cylinder 26 drives the pressure plate 27 to move forward, so that the pressure plate 27 is pressed against the valve rocker arm, and then cooperates with the use of the arc baffle 11 to lock and fix the rocker arm. Then the hydraulic cylinder 3 drives the fixed frame 4, the motor 15, and the chamfering head 6 to move downward, and the fixed frame 4 drives the two lifting plates 8 to move downward. The lifting plate 8 applies a thrust to the connecting tube 22, and the connecting tube 22 applies a thrust to the push rod 21. The push rod 21 pushes the moving plate 16 forward, so that the positioning head 17 moves forward and presses against the positioning seat 10, and the spring 23 is in a compressed state, so that the turning table 12 is locked and fixed. The motor 15 drives the chamfering head 6 to rotate, which is convenient for chamfering the inner hole of the valve rocker arm. When one side is chamfered, the hydraulic cylinder 3 drives the fixed frame 4, the motor 1 5, and the chamfering head 6 to move up synchronously, and the two lifting plates 8 move up synchronously. The lifting plate 8 applies an upward pulling force to the connecting tube 22, and the push rod 21 pulls the movable plate 16 back to separate the positioning head 17 from the positioning seat 10, thereby loosening the turning table 12. The motor 2 15 drives the turning table 12 to rotate, and the valve rocker arm can be turned over, which is convenient for chamfering the other side. It is highly practical and replaces the traditional manual loosening and turning of the valve rocker arm, saving time and effort and having high processing efficiency.
