[0038] Working principle:

[0039] When actually using the throttle valve shaft long groove symmetry and angle detection tooling, the operator can insert one end of a throttle valve shaft into the inside of a set of fixed orifice plates 18 by hand. One end of the throttle valve shaft can be inserted into the inside of a set of angle grooves 19. Then, rotate the handwheel. The handwheel can drive the wire lever 4 to rotate. Since the wire lever 4 and the lead screw sleeve 5 are in threaded cooperation with each other, the rotating wire lever 4 can push the lead screw sleeve 5 to move. The moving lead screw sleeve 5 can make two moving plates 7 move through two socket plates 6 and two support screws 23. The two moving plates 7 can drive two positioning pieces 11 to move through two concave seats 9. When one set of positioning pieces 11 is inserted into the long keyway of the throttle valve shaft, it indicates that the symmetry and angle of the long keyway of the throttle valve shaft are qualified. When one set of positioning pieces 11 cannot be inserted into the long keyway of the throttle valve shaft, this set of positioning pieces 11 can stop. As the lead screw sleeve 5 continues to move, one set of concave seats 9 on the same side can press one set of push switches 14 on the same side. Then, one set of buzzer alarms 13 on the same side can work and emit a sound, indicating that the symmetry and angle of the long keyway of the throttle valve shaft are unqualified. At the same time, the operator can insert another throttle valve shaft into the inside of another set of fixed orifice plates 18 by hand, and then rotate the handwheel in the reverse direction. The lead screw sleeve 5 moves in the reverse direction, enabling another set of positioning pieces 11 to detect another throttle valve shaft. Repeating the above operations can continuously complete the detection of multiple throttle valve shafts. By setting the concave frame 2, wire lever 4, lead screw sleeve 5, moving plate 7, concave seat 9, and positioning piece 11, the replacement of multiple throttle valve shafts can be completed without stopping the detection work of the throttle valve shaft, improving the working efficiency of the throttle valve shaft long groove symmetry and angle detection tooling. At the same time, when it is necessary to detect the long keyways of throttle valve shafts with different sizes, using the threaded cooperation between four groups of second threaded through holes 26 and four groups of adjusting bolts 27, the operator rotates the four groups of adjusting bolts 27 counterclockwise by hand, and can insert two positioning pieces 11 of the qualified size into the inside of two concave seats 9 respectively. Then, rotate the four groups of adjusting bolts 27 clockwise. When the four groups of adjusting bolts 27 are respectively in contact with two positioning pieces 11 of the qualified size, the installation of two positioning pieces 11 of the qualified size is completed. Then, using the threaded cooperation between two groups of first threaded through holes 20 and two groups of fastening bolts 21, the operator rotates the two groups of fastening bolts 21 clockwise and counterclockwise by hand, and can adjust the use positions of the two groups of fastening bolts 21. The two groups of fastening bolts 21 can limit the lead screw sleeve 5. Using the control panel, shorten the four groups of electric telescopic rods 16, and can place the positioning orifice plates 22 of the appropriate size between two right-angle plates 17 on the same side. Then, using the control panel, extend the four groups of electric telescopic rods 16. When the four right-angle plates 17 clamp the two positioning orifice plates 22 of the appropriate size, the installation of two positioning orifice plates 22 of the appropriate size is completed. Move the two support screws 23 up and down, and can adjust the use height of two positioning pieces 11 of the qualified size through the two moving plates 7. When two positioning pieces 11 of the qualified size are moved to the appropriate height, using the threaded cooperation between the two support screws 23 and the four support nuts 24, the operator rotates the four support nuts 24 clockwise and counterclockwise by hand,When the four groups of support nuts 24 are respectively in contact with the two groups of positioning hole plates 22, the use height of the two groups of moving plates 7 is fixed. By providing the concave plate 3, the support screw 23, the fastening bolt 21 and the adjusting bolt 27, it is possible to adapt to the detection of throttle shafts of various sizes, and the practicality of the detection tool for the symmetry and angle of the long groove of the throttle shaft is improved.
