[0053] In the valve body feeding station, the workpiece is manually placed and clamped by the second clamping tool 41, the second clamping tool 41 is rotated to the end piece assembly station with the second rotary disc 4, the fourth feeding assembly 9 carries the end piece from the output end of the fourth feeding assembly 54 and sleeves it on the end of the valve body. When the second clamping tool 41 is rotated to the transfer assembly station, the first rotary disc 2 is carried from the unloading station to the valve core of the valve body by the transfer mechanism 3 for press fitting, thereby forming a three-way valve product. Then, the second clamping tool 41 is rotated to the unloading detection station, the material is taken out, and the torque is detected by manual operation at the torque testing mechanism 11.

[0054] The operation principles of each feeding mechanism are basically the same, and each feeding mechanism is used for carrying the parts from the feeding assembly to the clamping tool through horizontal transverse movement and vertical lifting; and the first feeding assembly 6, the second feeding assembly 7 and the fourth feeding assembly 9 are the same in structure, and only the clamping jaws for clamping the parts are different.

[0055] Taking the fourth feeding assembly 9 as an example, the fourth feeding assembly 9 comprises a support rod 901 fixedly connected with the machine table 1, a mounting plate 902 fixedly installed on the support rod 901, a lifting plate 903 arranged on the mounting plate 902 and capable of lifting, a side plate 904 fixedly connected to one side of the lifting plate 903, a sliding plate 905 installed on the side plate 904 and capable of moving horizontally, and a chuck assembly 906 connected to the lower end of the sliding plate 905.

Similarly, under the driving of the second telescopic assembly 305, the transfer chuck 309 can move the rotary handle product to the position corresponding to the valve core on the valve body. Then, the output end of the first telescopic assembly 303 is extended to drive the pressing head 308 to move downward relative to the support 307, so that the lower end of the rotary handle product is pressed into the corresponding position of the valve body.

[0059] The second telescopic assembly 305 is used to ensure that the transfer chuck 309 can move the rotating handle product to the position corresponding to the valve core on the valve body, and the first telescopic assembly 303 is used to drive the pressure head 308 to press the rotating handle product into the valve body.

[0061] Three-way valve assembly process: at the valve body feeding station, the valve body is placed on the second clamping tool 41 by manual operation, and is clamped by the second clamping tool 41, at this time the end to be assembled of the valve body extends to the outermost side; the second rotating disc 4 drives the valve body to rotate to the end piece assembly station, and the fourth feeding assembly 9 grabs the end piece from the output end of the fourth feeding assembly 54 and assembles it on the end of the valve body; then the valve body rotates to the transfer assembly station, the transfer mechanism 3 grabs the rotating handle product from the discharging station, and then presses it onto the valve body, thereby completing the assembly of the three-way valve.

[0062] Rotating handle product transfer process: the second telescopic assembly 305 near the first rotating disc 2 drives the support 307, the pressure head 308 and the transfer chuck 309 to move downward as a whole, the transfer chuck 309 clamps the rotating handle product, and then moves upward to a safe position as a whole; under the drive of the rotating assembly 304, the second telescopic assembly 305, the support 307, the pressure head 308 and the transfer chuck 309 rotate 180 degrees as a whole to the upper side of the valve body, the support 307, the pressure head 308 and the transfer chuck 309 are driven by the second telescopic assembly 305 to move downward to the pressing height, and then the pressure head 308 is driven by the first telescopic assembly 303 to move downward relative to the support 307, so that the rotating handle product is pressed and assembled onto the valve body.

[0063] Torque test procedure: the three-way valve product is rotated to the discharging detection station with the second clamping tool 41, the material is taken, and then the torque is detected by the torque test mechanism 11; the product is placed in the rotating head of the torque tester, the torque tester is zeroed, the product is slowly and uniformly twisted, the initial torque is tested, after completion, the torque tester is zeroed, the product is rotated, and the subsequent static torque is tested.
