Specific embodiment
With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment.
As shown in Figure 1 and Figure 2, the valve seat bore hole tapping tool of the present embodiment, including connecting flange 1,1 side of connecting flange
It is fixedly connected with support plate 2, stiffening plate 6 is also connected between support plate 2 and connecting flange 1, and open up waist-shaped hole 21 in support plate 2,
Support plate 2 is located at placement valve seat positioning pin 3 on waist-shaped hole 21, connects bolt 31 and passes through the connection of waist-shaped hole 21 below support plate 2
Valve seat positioning pin 3 is connected in support plate 2 in the threaded hole of 3 lower end of valve seat positioning pin, and valve seat positioning pin 3 can be made along waist
Type hole 21 is mobile, and valve seat is set on valve seat positioning pin 3, is arranged on valve seat for the fastening by seat compression in support plate 2
Gasket 4, fastening gasket 4 are connected on valve seat positioning pin 3 by fastening bolt 41, and support plate 2 is located at the piston rod connection of valve seat
End two sides are all connected with screw connecting plate 22, and the adjusting screw 5 parallel with waist-shaped hole 21 is all connected on screw connecting plate 22, adjust spiral shell
The tip of nail 5 is towards the piston rod connecting pin of valve seat.
Tooling in use, be fixed on lathe, then by the valve seat bore hole tapping tool of the present embodiment by connecting flange 1
Suitable valve seat positioning pin 3 is selected according to the diameter of valve seat through-hole and is connected in support plate 2 by connecting bolt 31, then will
The through-hole of valve seat is set on valve seat positioning pin 3, then by fastening gasket 4 and fastening bolt 41, by valve seat and valve seat positioning pin 3
It is connected as an entirety, valve seat is positioned, then by the adjusting screw 5 of adjusting two sides, the left-right position of valve seat is adjusted,
So that the Working position of the piston rod connecting pin of valve seat is directed at lathe process drill bit, lathe can be started, carries out bore hole screwing operation.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape
The modification of formula.
