[0025] In this application, the water pump end cover is placed in the installation fixture 3, and the dynamic ring and the static ring are placed in the corresponding pressing positions of the water pump end cover. The servo electric cylinder 5 drives its extension rod 6 to retract and retract, and the pressure rod 8 is pressed against the dynamic ring and the static ring for press-fitting. The servo electric cylinder 5 can effectively control the stroke of the pressure rod 8 for pressing the dynamic ring and the static ring, and the pressure detection mechanism 7 can effectively control the pressing force of the pressure rod 8 for pressing the dynamic ring and the static ring.

[0026] The servo electric cylinder 5 is a modular product that integrates a servo motor and a lead screw. The cylinder body of the servo electric cylinder 5 is set on the press-fit top plate 4, and the lead screw is set in the cylinder body. The output shaft of the servo motor is connected to a high-precision planetary reducer. The output end of the high-precision planetary reducer is connected to the lead screw through a synchronous belt and a synchronous pulley. A drive block is slidably installed on the cylinder body, and the lead screw is threadedly connected to the drive block. The extension rod 6 is connected to the drive block. The lead screw is driven to rotate by the servo motor, and the lead screw drives the drive block to slide, thereby driving the extension rod 6 to slide and extend in the vertical direction.

[0027] Reference Figure 2 and Figure 3 As shown, the pressure detection mechanism 7 includes a fixing seat 71, a pressure sensor 72 and a connecting pressure head 73. The pressure sensor 72 is a spoke-type tensile pressure sensor 72. The spoke-type pressure sensor 72 includes a housing 721 and a pressure measuring component 722 arranged in the housing 721.

[0028] The center of the fixed seat 71 is connected to the end of the extending rod 6 of the servo cylinder 5, that is, a fixed threaded hole 711 is provided at the center of the fixed seat 71, and the end of the extending rod 6 of the servo cylinder 5 is provided with a fixed threaded section 61 that matches the fixed threaded hole 711 of the fixed seat 71.

[0029] The pressure sensor 72 is fixed to the lower surface of the fixing seat 71 by a locking screw 74. There are multiple locking screws 74, and the multiple locking screws 74 are distributed along the circumferential direction of the outer shell 721 of the pressure sensor 72. The end of the locking screw 74 is threadedly installed on the lower surface of the fixing seat 71. After the pressure sensor 72 is fixed to the lower surface of the fixing seat 71, the outer shell 721 of the pressure sensor 72 is in contact with the lower surface of the fixing seat 71, and the pressure measuring component 722 of the pressure sensor 72 does not contact the lower surface of the fixing seat 71.

[0030] The connecting pressure head 73 is connected to the lower surface of the pressure sensor 72. A mounting threaded hole 75 is provided in the middle of the pressure sensor 72. Specifically, the mounting threaded hole 75 is provided on the pressure measuring component 722 of the pressure sensor 72. A mounting hole is provided in the center of the connecting pressure head 73. A mounting bolt 76 is provided in the mounting hole, the end of which is threadedly connected to the mounting threaded hole 75. The pressure sensor 72 is provided with an upper abutment edge 77 surrounding the mounting threaded hole 75, and the connecting pressure head 73 is provided with a lower abutment edge 78 surrounding the mounting hole. The upper abutment edge 77 abuts against the upper abutment edge 78 to form a pressure measurement gap 79 between the pressure sensor 72 and the connecting pressure head 73. The connecting pressure head 73 does not contact the housing 721 of the pressure sensor 72.

[0031] The pressure rod 8 is connected to the lower surface of the connecting pressure head 73 by a fastening bolt 9. The pressure rod 8 includes a base 81 and a press rod 82 arranged in the center of the base 81. A plurality of fastening bolts 9 are provided, and the plurality of fastening bolts 9 are distributed along the circumferential direction of the base 81.

[0032] Therefore, when the pressure rod 8 is pressed onto the dynamic ring and the static ring, the pressing force at the end of the pressure rod 8 will be transmitted to the connecting pressure head 73, and then transmitted to the pressure measuring component 722 of the pressure sensor 72 via the connecting pressure head 73 to measure the pressing force.

[0033] Reference Figure 1 and Figure 4 As shown, the mounting fixture 3 includes a mounting base 31 and a folding connector 32 disposed on the side of the mounting base 31.

The hinge-type male block 322 is fixed to the mounting base 31.

[0034] The installation base plate 31 is covered with a base plate protection pad.

[0035] By folding the mounting base 31 to a horizontal state, the mounting base 31 can be laid flat on the workbench 1. By positioning the water pump end cover through the positioning hole 33, the dynamic ring and the static ring are placed in the installation position where the water pump end cover is to be pressed. Subsequently, the servo electric cylinder 5 drives the extension rod 6 to move downward until the pressure rod 8 is pressed onto the dynamic ring and the static ring. On the one hand, the servo electric cylinder 5 can effectively control the stroke of the pressure rod 8 for pressing the dynamic ring and the static ring. On the other hand, the pressure detection mechanism 7 can effectively control the pressing force of the pressure rod 8 for pressing the dynamic ring and the static ring, thereby effectively improving the pressing effect of the dynamic ring and the static ring, and thus improving the production quality of the product.
