The difficulty of processing overall with reducing sleeve 12 of pedestal 11, improves its processing efficiency.
Certainly, if the attachment structure to be realized of support base 8 itself is more, support base 8 can also be disassembled to be more
Part after be combined, but consequently, it is possible to may result in the cumulative errors of these parts after the combination excessive, cause most
The structure precision of the support base 8 of final shaping unit receives considerable influence, and can increase assembling procedure, reduces processing efficiency, therefore,
When being processed to support base 8, support base 8 can be disassembled according to the basic function to be realized of support base 8 so that
The structure of support base 8 is unlikely to produce the problem of part is excessive while more simplifying.
Preferably, valve seat 7 has the first guide part 13 for coordinating installation with nut assembly 18, and the first guide part 13 is located at valve
Seat 7 is close to the periphery of the one end of nut assembly 18.Nut assembly 18 is set in the periphery of valve seat 7, and is formed with the first guide part 13
It is oriented to and coordinates, it is ensured that the axiality coordinated between nut assembly 18 and valve seat 7, improves guiding essence when needle 10 moves
Degree, prevents deviation phenomenon occur in the motion process of needle 10.
Preferably, rotor assembly 2 also includes screw rod 16 and valve needle cover 17, and needle 10 is arranged in valve needle cover 17, and from valve
One end of needle guard 17 is stretched out, and the other end of screw rod 16 from valve needle cover 17 is stretched into valve needle cover 17, and with the drive connection of needle 10, valve
The inner circumferential of seat 7 has the second guide part 14 that the motion to valve needle cover 17 is oriented to.Because the first guide part 13 and second is led
Processed to portion 14 on valve seat 7, therefore be more prone to ensure the axiality between the first guide part 13 and the second guide part 14,
Therefore, it is oriented to by installation of first guide part 13 to nut assembly 18, by the second guide part 14 to valve needle cover 17
Motion is oriented to, and then the motion to needle 10 is oriented to, and the coaxial of nut assembly 18 and needle 10 can be effectively ensured
Degree, and then ensure the axiality between screw rod 16 and needle 10, ensure the kinematic accuracy of needle 10.
The inner circumferential of valve seat 7 also includes the 3rd guide part 15 that stepped hole is cooperatively formed with the second guide part 14, and needle 10 wraps
Path section and big footpath section are included, needle 10 is oriented to by path section and the 3rd guide part 15 to be coordinated.Due to the 3rd guide part 15 still
It is provided on valve seat 7, therefore is more prone to ensure the first guide part 13, the second guide part when being processed valve seat 7
14 and the 3rd axiality between guide part 15, machining accuracy is improved, while reduce difficulty of processing.Similarly, by needle 10
