[0041] Further preferably, a baffle 73 is horizontally arranged on one side of the upper end of the pusher 71. After the valve guide 5 has been received in the pusher cavity A and the pusher cavity B of the pusher 71, under the action of the pusher power member 72, the pusher cavity A and the pusher cavity B of the pusher 71 are aligned with one set of guide seat cavities, and two valve guides 5 fall into one set of guide seat cavities. During the movement of the pusher 71, the baffle 73 can prevent the valve guides 5 in the nylon tube seat A 710 and the nylon tube seat B 711 from continuing to fall.

[0044] The following is a detailed description of the process of using the valve guide press-fitting machine of the present invention to press-fit the valve guide 5 onto the cylinder head 1:

[0045] The feeding mechanism 6 supplies the valve guide 5 through the main nylon tube 12. After the valve guide 5 reaches the feed pipe seat 92 of the material distribution assembly 9 through the main nylon tube 12, the action end of the material distribution power member 96 extends out, and the material distribution cavity A on the slide block 95 is located directly below the feed port 941 of the slide block 94. The valve guide 5 falls into the material receiving cavity A through the feed port 941, and then the action end of the material distribution power member 96 continues to extend, and the material receiving cavity A leaves the directly below the feed port 941 until it is aligned with the discharge port A 942, and the valve guide falls into the discharge port A 942. In order to prevent the material distribution power member 96 from extending too far, a limit screw 98 is also provided on the second end plate 993. When the receiving cavity A is aligned with the discharge port A 942, the receiving cavity B on the slider 95 arrives just below the feed port 941, and another valve guide 5 falls into the receiving cavity B through the feed port 941. The action end of the material distribution power member 96 is retracted, and the receiving cavity B leaves just below the feed port 941 until it is aligned with the discharge port B 943, and the valve guide 5 falls into the discharge port B 943. When the receiving cavity B is aligned with the discharge port B 943, the receiving cavity A on the slider 95 arrives just below the feed port 941. Under the action of the material distribution power member 96, the slider 95 reciprocates horizontally, and the valve guide 5 falls alternately from the discharge port A 942 and the discharge port B 943.

[0046] The valve guide 5 falls from the discharge port A 942 into the discharge pipe seat A 931, and from the discharge port B 943 into the discharge pipe seat B 932, and continues to fall into the branch nylon tube A 131 connected to the discharge pipe seat A 931, and the branch nylon tube B 132 connected to the discharge pipe seat 932B. The valve guide 5 falls into the branch nylon tube seat A 710 through the branch nylon tube A 131, and falls into the branch nylon tube seat B 711 through the branch nylon tube B 132.

[0047] The valve guide 5 falls into the pusher cavity A and the pusher cavity B on the pusher 71 through the nylon support tube seat A 710 and the nylon support tube seat B 711, and the valve guide 5 falling into the pusher cavity A and the pusher cavity B falls into a group of loading seat grooves of the loading seat 75 through the guide seat 74. When the valve guide 5 falls into a group of loading seat grooves of the loading seat 75, another valve guide 5 falls into the pusher cavity A and the pusher cavity B. The action end of the pusher power member 72 extends, the pusher 71 moves horizontally, and the pusher cavity A and the pusher cavity B of the pusher 71 move to the top of another group of loading seat grooves, and the valve guides 5 in the pusher cavity A and the pusher cavity B fall into another group of loading seat grooves of the loading seat 75 through the guide seat 74. During the movement of the pusher 71, due to the effect of the baffle 73, the valve guide 5 located in the nylon pipe seat A 710 and the nylon pipe seat B 711 will not continue to fall.

[0048] Then, the action end of the material pushing power member 72 is retracted, and the above process is continued to supply the next group of four valve guides 5 to the material loading seat 75.

[0049] In order to avoid interference between the four valve guides 5 and the guide seat 74, the action end of the loading seat lifting power member 79 extends out, and the loading seat 75 moves down. The rotary power member 77 works, driving the loading seat 75 to rotate to the bottom of the pressure head of the press-fitting mechanism 4. The action end of the loading seat lifting power member 79 is retracted, and the loading seat 75 moves up. The four valve guides 5 are respectively inserted into the four pressure heads, and the four ball screws in each pressure head squeeze the valve guide 5 to prevent the valve guide 5 from falling. The action end of the loading seat lifting power member 79 extends out, and the loading seat 75 moves down. Then, under the action of the rotary power member 77, the loading seat 75 rotates to the bottom of the guide seat 74.

[0050] The operator carries the cylinder head 1 to be assembled with the valve guide 5 to the loading conveying mechanism 10. The carrying device 8 carries the cylinder head 1 to the pressing station, the pressing mechanism 3 presses and positions the cylinder head 1, and the pressing mechanism 4 presses the valve guide 5 into the cylinder head 1. The carrying device 8 carries the processed cylinder head 1 to the unloading conveying mechanism 11.
