[0002] The fuel injector is a precision component with very high processing accuracy. It is required to have a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. The fuel injector receives the injection pulse signal sent by the ECU and accurately controls the fuel injection amount. The current fixture for clamping the inclined hole must cope with inclined holes in different directions during the processing of the inclined holes in the injector body and ensure the accuracy of their inclination angles.

[0003] To solve the above problems, the existing technology patent (CN212762327U) discloses a fixture for processing inclined holes in an injector body with adjustable tilt angle. The second hydraulic cylinder is driven by a hydraulic pump to extend and retract the second tooth plate, thereby driving the top end of the second splint to tilt through the second pull rod connected between the top end of the second splint and the second tooth plate. The second tooth plate is driven by the third tooth plate to tilt in another direction, thereby changing the tilt orientation of the injector, further facilitating the drilling rig to process the inclined hole of the injector, reducing labor costs, improving work efficiency, and making the tilt orientation of the injector more comprehensive, thereby improving the applicability of the body.
