The workbench 7 serves as a base and also as an operating table for pressing the shaft Y-shaped sealing ring 100 to the workpiece 200 and performing airtightness detection after the shaft Y-shaped sealing ring 100 is installed.

[0033] like Figure 1 , Figure 2 As shown, the sliding assembly 9 in this embodiment is composed of a linear guide rail and a slider, the linear guide rail is vertically fixed on the support frame 5, and the slider is fixed to the sliding bracket 83. The sliding bracket 83 includes a vertical plate and a horizontal plate, and one side of the horizontal plate is fixedly connected to the vertical plate.

[0034] The sliding bracket of the press-fitting mechanism is equipped with a clamping telescopic member and a fixed plate 812 , and the lower end of the slide rod of the clamping telescopic member is equipped with a retaining limit sleeve 88 ; the clamping telescopic member of this embodiment adopts a clamping elbow clamp 86 and is installed on the horizontal plate of the sliding bracket 83 .

[0035] A plurality of sealing rings for placing fan blades 89 arranged in a circumferential direction are arranged in the lower port of the retaining limit sleeve 88, and the upper part of the plurality of sealing rings for placing fan blades 89 is hinged to the retaining limit sleeve 88. A spring is installed on the retaining limit sleeve 88 and / or the sealing ring for placing fan blades 89, and the lower part of the sealing ring for placing fan blades 89 is swung by the spring. The lower part of the plurality of sealing rings for placing fan blades 89 has a protrusion for placing a Y-shaped sealing ring 100 for the shaft.

[0036] The fixed plate 812 is arranged below the sealing ring where the fan blade 89 is placed. A guide hole is opened on the fixed plate 812, and a sealing ring guide sleeve 811 is installed in the guide hole. A positioning tool 10 for placing the workpiece 200 is fixedly installed on the workbench 7 below the fixed plate 812.

[0037] The compression telescopic part pushes the sealing ring with the Y-type sealing ring 100 for the shaft through the sliding rod to place the sealing ring through the sealing ring guide sleeve 811 installed in the guide hole at the lower part of the fan blade 89, and installs the Y-type sealing ring 100 for the shaft onto the workpiece 200; the positioning tool 10 is provided with an airtight detection mechanism 11 under the workbench 7 for detecting the installation condition of the Y-type sealing ring for the shaft.

[0038] Continue to see Figure 1As shown, the press-fitting mechanism 8 of this embodiment can slide up and down on the support frame 5 through the sliding assembly 9. The two ends of the drag chain 2 are respectively fixed on the support frame 5 and the press-fitting mechanism 8 to arrange the air pipe and wires. The airtight detection mechanism 11 is fixed below the fixed platform 7. The shaft Y-shaped sealing ring 100 is placed on the press-fitting mechanism 8, and the workpiece 200 to be installed with the sealing ring is placed on the positioning tool 10.

[0039] like Figure 2 As shown, the press-fitting mechanism 8 in this embodiment includes a handle 81, a lifting ring 82, a sliding bracket 83, a lower limit detection sensor 84, a locking mechanism 85, a press-fitting elbow clamp 86, an upper limit detection sensor 87, a retaining limit sleeve 88, a sealing ring placing fan blade 89, a first adjustable stopper 810 for the lower limit of the elbow clamp, a sealing ring guide sleeve 811, a fixing plate 812 and a second adjustable stopper 813 for the lower limit of the press-fitting mechanism.

[0040] The handle 81 , the lifting ring 82 , the locking mechanism 85 and the press-fit toggle clamp 86 are fixed on the sliding bracket 83 , and the lifting ring 82 is connected to the sliding bracket 83 through a transverse support rod to increase the space in which the balancer 1 and the drag chain 2 can be assembled.

[0041] The limit sleeve 88 detects the upper and lower limit position states of the press-fitting toggle clamp 86 by triggering the upper limit detection sensor 87 and the lower limit detection sensor 84. The hanging hook of the balancer 1 body is fixed at a certain position, and the lower cable safety buckle is connected to the lifting ring 82 in the press-fitting mechanism 8 to realize the automatic lifting of the press-fitting mechanism 8.

[0042] There are a total of four sealing ring placed fan blades 89 in this embodiment, which are symmetrically installed in the lower port of the retaining limit sleeve 88. The upper end of the sealing ring placed fan blade 89 is installed in the retaining limit sleeve 88 through a fixed hinge or an articulated shaft to achieve support, and the lower end can swing along the fixed hinge or articulated shaft and open by spring force; at the same time, the retaining limit sleeve 88 is used to limit the opening angle of the four sealing ring placed fan blades 89.

[0043] The shaft Y-shaped sealing ring 100 is installed at the step position at the lower end of the boss on which the fan blade 89 is placed, and automatic loading is achieved through manual placement or a suitable feeding mechanism.

[0044] like Figure 3 , Figure 4 As shown, the locking mechanism 85 in this embodiment includes a sensor trigger bolt 851 , an oil-free bushing mounting seat 852 , a flange-type oil-free bushing 853 , a locking shaft 854 and a side plate 855 .

[0045] The flange type oil-free bushing 853 is fixed on the oil-free bushing mounting seat 852, and the oil-free bushing mounting seat 852 is fixed on the side plate 855. The locking shaft 854 is installed in the flange type oil-free bushing 853, and is driven to extend and retract by the locking cylinder 856. The locking shaft 854 is used in conjunction with the locking oil-free bushing 4 provided on the support 5. The sensor trigger bolt 851 is used in conjunction with the locking proximity sensor 3 installed on the support 5 to detect whether the press-fitting mechanism 8 has reached the locking position.

[0046] like Figure 4 As shown, the airtight detection mechanism 11 in this embodiment includes an O-ring 111, a lifting limiter 112, a lifting cylinder 113, an inflatable column 114, a pneumatic joint 115, a floating joint 116 and a fixed mounting plate 117. Among them, the inflatable column 114 is provided with four inflatable holes 1141.

[0047] The inflatable column 114 passes through the guide sleeve 12, which guides the inflatable column 114. The guide sleeve 12, the positioning tool 10, the sealing ring guide sleeve 811 and the retaining limit sleeve 88 are coaxial. The digital display air pressure sensor 6 is connected to the pneumatic joint 115 through a pipeline to detect the air pressure at the inflatable hole 1141.

[0048] The working process of the present invention is as follows:

[0049] The workpiece 200 to be installed with the sealing ring is manually placed on the positioning tool 10 in the correct direction, the handle 81 is grasped by the left hand, and the sealing ring pressing mechanism 8 is pressed downward to the locking position. The sensor triggers the bolt 851 to trigger the locking proximity sensor 3, and the piston rod of the locking cylinder 856 automatically extends to drive the locking shaft 854 to be inserted into the locking oil-free bushing 4, thereby realizing the locking of the pressing mechanism 8 in place.

[0050] Take the Y-shaped sealing ring 100 for the shaft and place it on the lower step position of the sealing ring placing fan blade 89. The sealing ring placing fan blade 89 fixes the Y-shaped sealing ring 100 for the shaft by elastic external tension.

[0051] Then, the press-fitting toggle clamp 86 is manually pulled to press-fit the shaft Y-shaped sealing ring 100 into the workpiece 200 to be installed with the sealing ring through the slide rod, and the limit sleeve 88 is kept to trigger the lower limit detection sensor 84; the press-fitting toggle clamp 86 is manually reset to keep the limit sleeve 88 triggered to the upper limit detection sensor 87. Then, the piston rod of the lifting cylinder 113 extends to drive the inflatable column 114 to rise and extend into the workpiece 200 after the shaft Y-shaped sealing ring 100 is installed.

[0052] The control system starts to inflate the airtight detection mechanism 11 through the pneumatic joint 115. If the shaft is installed in place with the Y-shaped sealing ring 100 and the direction is correct, a closed cavity is formed at the inflation hole 1141, and the air pressure value can rise to the specified range within the set time. The digital air pressure sensor 6 sends a qualified signal to the control system, and the piston rod of the locking cylinder 856 drives the locking shaft 854 to retract, and the pressing mechanism 8 returns to its position under the action of the balancer 1, and the work is completed.

[0053] If the air pressure value does not rise to the specified range within the set time, the digital air pressure sensor 6 sends a failure signal to the control system, indicating that the Y-type sealing ring 100 for the shaft is not press-fitted successfully, and the system alarms.

[0054] The technical contents not described in detail in the present invention are all known technologies.
