A press-fitting device for press-fitting the valve guide 5 to the cylinder head 1 is also arranged on the frame 2 at the press-fitting station. The press-fitting device includes a pressing mechanism 3 and a pressing mechanism 4. When the valve guide is pressed onto the cylinder head, the pressing mechanism 3 is used to press and position the cylinder head 1. The pressing mechanism 4 is used to press the valve guide 5 onto the cylinder head 1. The pressing mechanism 3 and the pressing mechanism 4 can choose to use conventional handling devices in the prior art. The working process and working principle of the pressing mechanism 3 and the pressing mechanism 4 are common knowledge to those skilled in the art and will not be described here. Alternatively, the pressing can be performed directly by manual labor.

[0026] The valve guide press machine further comprises a valve guide feeding mechanism 7, which is used to supply the valve guide 5 to the press station.

[0027] A material unloading station is provided downstream of the press-fitting station, and a material unloading conveying mechanism 11 is provided at the material unloading station; after the valve guide 5 is press-fitted to the cylinder head 1, the handling device 8 carries the cylinder head 1 to the material unloading conveying mechanism 11.

The material unloading conveying mechanism 11 is a conventional conveying mechanism capable of conveying the cylinder head 1, and its specific structure and conveying process are common knowledge to those skilled in the art, and will not be described in detail here.

[0028] Combination Figure 1 , Figure 2 ,as well as Figure 3 As shown together, the feeding mechanism 7 of the valve guide comprises a feeding bracket 76 fixedly arranged on the frame 2, and the feeding bracket 76 comprises a horizontal plate 761, and two through holes are vertically arranged on the horizontal plate 761, namely through hole A and through hole B, and a pusher 71 is arranged below the horizontal plate 761, and two pusher cavities are arranged on the pusher 71, and the two pusher cavities are respectively pusher cavity A and pusher cavity B, and the distance between pusher cavity A and pusher cavity B is equal to the distance between through hole A and through hole B. Two nylon pipe support seats are arranged on the upper surface of the horizontal plate 761, and the two nylon pipe support seats are respectively nylon pipe support seat A 710 and nylon pipe support seat B 711. The branch nylon tube seat A 710 is connected to the through hole A, and the branch nylon tube seat A 710 is connected to the branch nylon tube A 131; the branch nylon tube seat B 711 is connected to the through hole B, and the branch nylon tube seat B 711 is connected to the branch nylon tube B 132.

[0029] A guide seat 74 is arranged below the pusher 71, and four guide seat cavities are arranged on the guide seat 74, two of which are in one group and the other two are in another group. The distance between each group of guide seat cavities is equal to the distance between the pusher cavity A and the pusher cavity B.

[0030] Preferably, the feeding mechanism 7 further comprises a pushing power piece 72, the action end of which is fixedly connected to the pushing piece 71, and the pushing piece 71 reciprocates horizontally under the action of the pushing power piece 72; the fixed end of the pushing power piece 72 is fixedly connected to the feeding bracket 76. The pushing power piece 72 is a cylinder, and of course, the pushing power piece 72 can also be a conventional power piece that can provide power, such as an oil cylinder, an electric cylinder, etc., which will not be described one by one here.

[0031] Further preferably, a baffle 73 is horizontally arranged on one side of the upper end of the pusher 71. The pusher 71 and the baffle 73 are preferably an integral structure. 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.

[0032] Preferably, the feeding mechanism 7 further includes a feeding seat 75, on which four feeding seat grooves are provided, and the four feeding seat grooves are respectively used to receive four valve guides 5 dropped from the guide seat 74. The feeding mechanism 7 further includes a rotary power member 77, the fixed portion of which is mounted on the feeding bracket 76, and the action portion of the rotary power member 77 is fixedly provided with a rotary frame 78, and the feeding seat 75 is fixedly connected to the rotary frame 78. The rotary power member 77 can be a rotary cylinder, and of course, other conventional power members capable of providing rotary power can also be selected, which will not be described one by one here.

[0033] Preferably, in order to prevent the valve guide 5 from interfering with the guide seat 74 during the rotation of the loading seat 75, the loading mechanism 7 further includes a loading seat lifting power member 79, the fixed end of which is fixedly connected to the action part of the rotary power member 77, and the action end of which is fixedly connected to the loading seat 75. The loading seat lifting power member 79 is preferably an oil cylinder, and of course, it can also be other conventional power members capable of providing power, such as an electric cylinder and a pneumatic cylinder, which will not be described in detail here.

[0034] 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:

[0035] The feeding mechanism 6 supplies the valve guide 5 through the main nylon tube 12, and the valve guide 5 reaches the distributing mechanism 9 through the main nylon tube 12. After the valve guide 5 comes out of the distributing mechanism 9, it falls into the branch nylon tube seat A 710 and the branch nylon tube seat B 711 respectively through the branch nylon tube A 131 and the branch nylon tube B 132. The distributing mechanism 9 can use a conventional structure in the prior art, and its working process and working principle are common knowledge to those skilled in the art, and will not be repeated here. Alternatively, the valve guide 5 coming out of the main nylon tube can be directly put into the branch nylon tube A 131 and the branch nylon tube B 132 by manual operation.

[0036] 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.

[0037] Then, the action end of the pusher power member 72 is retracted, and the above process is continued to supply the next group of valve guides 5 to the loading seat 75, where one group includes four valve guides 5.

[0038] 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 at the same time, the loading seat 75 moves up, and 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.

[0039] 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.
