[0025] Working process of the present invention:

[0026] In a EPS universal joint fork intelligent manipulator broaching machine of the present invention, during operation, the universal joint forks are sequentially arranged and placed on two conveyor belts. The arranging and conveying mechanism can sequentially convey the universal joint forks forward (wherein, the connecting hubs of two adjacent universal joint forks abut against each other, and a gap is formed between the fork heads of two adjacent universal joint forks for the baffle plates of the first blanking mechanism and the second blanking mechanism to insert). Through the cooperation of the first blanking mechanism and the second blanking mechanism, one universal joint fork can be conveyed forward on each conveyor belt each time. The specific process is as follows: There is always one universal joint fork waiting for feeding temporarily stored between the baffle plates of the first blanking mechanism and the second blanking mechanism. When feeding is required, the second blanking mechanism controls its baffle plate to move upward, and the temporarily stored universal joint fork waiting for feeding can be conveyed forward until it reaches the feeding station at the positioning bracket. After the universal joint fork at the temporary storage position leaves, the second blanking mechanism controls its baffle plate to move downward and reset. Then the first blanking mechanism controls its baffle plate to move upward, so that the subsequent universal joint fork can be conveyed forward. After a universal joint fork fills the temporary storage position, the first blanking mechanism controls the baffle plate to move downward and reset to wait for the next replenishment position; After the universal joint forks on the two conveyor belts reach the feeding station, they are grabbed by two feeding manipulators, and the universal joint forks at the feeding station are conveyed and placed into the central positioning cavity of the positioning disk. Through the positioning mechanism, it moves forward until the pressing rod is above the fork head of the universal joint fork. Then the pressing cylinder acts to press the universal joint fork on the positioning disk. The first sliding seat moves forward to convey the positioned universal joint fork to the spline broaching station for processing. After processing is completed, the positioning and feeding tooling resets and waits for blanking. Blanking can be achieved through the blanking manipulator or manual blanking. The operation is simple and the production efficiency can be improved.

[0027] The above embodiments are illustrative of the present invention, not restrictive thereof. Any simple transformation of the present invention also belongs to the protection scope of the present invention.
