[0072] Firstly, the ball head seat 16 is placed in the positioning groove 22 of the workbench 10, and the mounting section 30, the connecting section 28 and the matching section 29 of the ball head seat 16 are respectively installed in the corresponding mounting groove 17, the connecting groove 18 and the matching groove 19, the controller controls the sliding block three 59 to start moving downward along the electric control sliding table three 58 until the lower bottom surface of the limiting block 62 is attached to the upper end surface of the groove 23, at this time, the limiting switch 24 is in contact with the lower bottom surface of the limiting block 62 and sends a signal to the controller, the controller controls the cylinder five 61 to extend and keep a certain pressure to press the ball head seat 16, after completion, the control cylinder four 43 starts to extend, drives the cylinder four 43 to extend, the cylinder four 43 drives the limiting rod 44 to insert into the matching hole 27 until the end surface of the limiting part 45 is attached to the right end surface of the matching section 29 of the ball head seat 16, at this time, the limiting switch 24 is attached to the end surface of the matching section 29, the limiting switch 24 sends a signal to the controller, the controller controls the cylinder to stop extending and keeps a certain pressure to press the ball head seat 16, the cylinder can also be used to press the ball head seat 16 without the control of the limiting switch 24 by selecting the stroke of the cylinder and the installation position of the cylinder, but this way requires the ball head seat 16 to have high precision requirements, after completion, the control sliding block one 36 moves to the uppermost position of the electric control sliding table, and then the rotating cylinder 33 is controlled to rotate to the place where the ball rod 25 is placed after the completion of the cooperation with the gasket 26, at this time, the gas claw 38 is in an open state, the control sliding block one 36 moves downward along the electric control sliding table to a specified position, the control gas claw 38 starts to retract to clamp the ball rod 25, after completion, the control cylinder moves downward, the suction cup 48 starts to work and tightly sucks the gasket 26, after completion, the sliding block one 36 moves upward to drive the ball rod 25 to displace, the rotating cylinder 33 is controlled to displace again to drive the ball rod 25 to reach the specified position, the control sliding block one 36 starts to move downward, the sliding block one 36 drives the ball rod 25 to enter the matching hole 27 of the matching end of the ball head seat 16, the downward displacement distance is set in advance according to the measurement, after reaching the specified position, i.e., the lower bottom surface of the gasket 26 abuts against the surface of the limiting boss 50, the control cylinder three 47 extends to drive the lower end surface of the limiting plate 49 to be in contact with the surface of the gasket 26, keeps a certain pressure to press the gasket 26, after completion, the controller controls the sliding table to displace to the central position of the workbench 10 until the surface of the matching claw 56 abuts against the surface of the ball head seat 16, after completion, the control cylinder one 54 starts to extend, at the same time, the mica heating sheet heats and processes the surface of the ball head seat 16, the cylinder one 54 drives the necking block 55 to combine and narrow, and performs extrusion necking on the surface of the ball head seat 16, after completion, the mica heating sheet stops working, the cylinder one 54 keeps the pressure, and the ball head seat 16 is air-cooled for a period of time, so that the ball head seat 16 can keep the necking shape, finally, the cylinder one 54 retracts, the sliding block two 51 displaces outward, and the limiting assembly and the correction mechanism 14 all return to the initial state and are separated from the ball head seat 16, and the completed ball head is taken out.

[0073] The above merely illustrates the specific embodiments of the present application, but the technical features of the present application are not limited thereto. Any simple change, equivalent replacement or modification made on the basis of the present application to solve the basically same technical problem and realize the basically same technical effect shall be included in the protection scope of the present application.
