For the oil passage cup plug mounting device in the preferred embodiment, when the press fitting operation of the oil passage cup plug 12 of the workpiece 11 is actually performed, the press fitting operation process mainly comprises the following steps:

(1) The operator places the workpiece 11 on the positioning fixture 2 of the apparatus in the correct manner, as shown in fig. 4, and the cup plug 12 on the guide ram 410 in the correct manner, after which the control switch 10 is activated;

(2) The clamping in-place detection unit 204 on the positioning clamp 2 detects whether the clamping of the workpiece 11 is in place; if the workpiece 11 cannot be clamped or the positioning fixture 2 has no workpiece 11, the equipment stops acting and automatically alarms; correspondingly, the interface of the PLC 7 can synchronously display the alarm content; similarly, when the in-place detection piece 409 on the press-fitting mechanism 4 detects that the cup plug 12 is not in place or no cup plug 12 is placed, an alarm is automatically given;

(4) After the workpiece 11 is pressed, the PLC controller 7 controls the hydraulic station 9 to output power to drive the press-fitting cylinder 403 to operate, and the slide module 404 is pushed by the press-fitting cylinder through the connecting pin 417 to move forward at a speed of about 50mm/s along the slide rail 412 from the zero position (the setting position of the zero position sensor 415). When the slide deceleration sensor 414 is located, the movement of the slide module 404 is decelerated, and the slide module continues to move forward at a speed of about 10mm/s until the stopper plate 408 abuts against the end face of the oil passage hole, and in the process, the guide ram 410 and the displacement detection module 405 are always stationary with respect to the slide module 404. When the retainer plate 408 contacts the end surface of the oil passage of the workpiece 11, the slide module 404 continues to move forward under the driving of the press-fitting cylinder 403, and the press-fitting spring 413 starts to be compressed. The displacement detecting probe 406 of the displacement detecting module 405 is also retracted due to being blocked by the front probe stopper 407, at this moment, the displacement detecting module 405 automatically defaults that the point is the detection zero point (referred to as point a), and the pressure detecting module 416 starts to operate after receiving the detection zero point signal of the displacement detecting module 405. When the sliding module 404 contacts the press-fitting limiting block 411 (referred to as a detecting point b), the sliding module stops moving due to being blocked, at this time, the press-fitting spring 413 and the displacement detecting probe 406 both reach the maximum compression amount, and the cup plug 12 is pressed into the oil passage designated position of the workpiece 11, so as to complete press-fitting;

(5) In the press-fitting process of (4), the displacement detecting module 405 records the press-fitting depth value (here, denoted as h, which is the distance between the measuring point a and the point b), and the pressure detecting module 416 records the maximum press-fitting force value (here, denoted as f) when the guide ram 410 moves from the point a to the point b. Correspondingly, the recorded values of h and f are stored and output to the interface of the PLC controller 7;

(6) And according to the press-fitting force range and the press-fitting size range set before machining, comparing h and f recorded by the PLC 7, and judging whether the press-fitting of the workpiece 11 is qualified. Namely, when h and f both meet the set range value, the dotting mechanism 5 performs mechanical dotting on the workpiece 11, and the oil duct cup plug of the workpiece 11 is determined to be qualified in press fitting. When one of the values h and f is out of tolerance or out of tolerance at the same time, the equipment stops acting and automatically alarms, and the interface of the PLC 7 displays alarm content;

(7) After the press mounting operation of the cup plug 12 of the workpiece 11 is finished, the press mounting mechanism 4 is controlled to reset to the zero position, the pressing mechanism 3 is reset, and manual blanking is carried out.

When the process (3) triggers the alarm, the equipment stops working, needs to be reset at the moment, returns to the process (1) again, repeats the process after rechecking, and is a qualified product after finishing. When the process (6) triggers an alarm, the equipment stops working, and needs to be reset to the process (7), and at the moment, the workpiece 11 is a defective product, needs to be marked and isolated, and cannot flow out.
