DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The valve core assembly tool of the present invention includes a base 1, a limit plate 2, a screw 3, a pressure shaft positioning plate 4 and a pressure shaft 5; the limit plate 2 is connected and fixed to the base 1 by the screw 3; the pressure shaft 5 is connected to the pressure shaft positioning plate 4. Among them, the base 1, the limit plate 2 and the screw 3 are fastened to form a positioning structure, and the pressure shaft positioning plate 4 and the pressure shaft 5 are fixed by interference fit to form a press-fit structure. The valve core 6 and the valve seat 7 are placed in the positioning structure, and the valve core 6 and the valve seat 7 are assembled and fixed by the press-fit structure; the positioning structure is used to accurately fix the position of the valve core 6 to ensure that the valve core 6 can be accurately fixed to the valve seat 7. The valve core 6 and the valve seat 7 are located in the base discharge position 8 of the base 1. The number of base discharge positions 8 is 4, and two groups of valve cores 6 and valve seats 7 are placed in each base discharge position 8, and the two groups of valve cores 6 and valve seats 7 are arranged back to back in the base discharge position 8. The pressure shaft 5 is equipped with a stopper step 11 to control the insertion depth. The total length of the stopper step 11 and the front end of the pressure shaft 5 determines the final insertion depth. By controlling the front end length of the pressure shaft 5, the tightness of the valve core 6 and the valve seat 7 is ensured. The pressure shaft 5 faces the hole 10 in the base 1. The hole 10 includes a front press-fit hole 12 and a rear press-fit hole 13. The pressure shaft positioning plate 4 corresponds to the external hydraulic press 9.

[0024] When using,

[0025] 1) Place the valve core 6 and valve seat 7 into the discharge position of the positioning structure (such as Figure 4 shown);

[0026] 2) Align the press-fit structure with the hole 10 of the positioning structure and place it in the positioner. Use the hydraulic press 9 to press the positioning structure. The front end of the pressing shaft 5 is pressed into the valve seat 7 to deform the inside of the valve seat. The deformed part is stuck in the groove reserved at the valve core 6, so that the valve core 6 and the valve seat 7 are fixed together (such as Figure 3 As shown), by controlling the position of the press-in hole on the base 1, the pressure shaft 5 can be smoothly positioned in the groove position on the valve core 6;

[0027] 3) Flip the positioning structure and press the back of the valve core 6. The base 1 has reserved press-in holes on the front and back sides (such as Figure 6 As shown), the press-fitting process of the valve core 6 and the valve seat 7 is completed.

[0028] The tooling of the present invention can control the number of valve cores 6 assembled in each batch by controlling the number of discharge positions on the base 1 (normally twice the number of discharge positions). The tooling can also realize automated assembly, with the valve core 6 and valve seat 7 being placed in the discharge position for press-fitting by a manipulator.
