When needing to detect the distance over bar of gear ring class part, standard component gear ring class part is taken, and be placed horizontally at water
The utility model is placed on standard component gear ring class part by flat desktop, and mobile shell 1 adjusts its position, until being installed on
Measuring head 14 on fixed arm 11 is embedded in the one tooth socket of standard component gear ring class part, and control travelling arm 12 slides, directly
Spherosome 17 to another measuring head 14 is embedded in corresponding tooth socket, and the display numerical value of electronic microcalliper 13 is zeroed；Take to
Gear ring class part is detected, and with above-mentioned step operation the utility model, last reads numerical value shown by electronic microcalliper 13, if
The numerical value is within the margin of tolerance, then being detected gear ring class part is qualified parts；In conclusion the utility model passes through circle
Sphere 17 imitates the effect of pole, the step of so as to avoid pole is placed, while detecting institute's value without being calculated, i.e.,
It can directly be compared with tolerance value, be finally reached the more convenient technical effect of distance over bar of detection gear ring class part.
The range of the utility model is the value range of fixed arm 11 and 12 relative distance of travelling arm, to adapt to multiple diameter
The detection of gear ring class part, as shown in figure 3, shell 1 equidistantly offers multiple threaded holes 18, fixed arm 11 be threaded with
The fixing bolt 19 that threaded hole 18 is threadedly engaged, when needing to adjust the fixation position of fixed arm 11, by fixing bolt 19 by spiral shell
Back-out in pit 18, behind mobile fixed arm 11 to corresponding position, again by the cooperation between fixing bolt 19 and threaded hole 18
Fixed arm 11 is installed；In conclusion by adjusting the installation site of fixed arm 11, so as to adjust fixed arm 11 and 12 phase of travelling arm
The value range adjusted the distance, and then reach the technical effect of the gear ring class part suitable for multiple diameter.
After the placement for completing the utility model, testing staff is needed to push travelling arm 12 manually, there are certain inconvenience,
Thus as shown in figure 3, being fixed with supporting block 20 inside shell 1, compression bullet is provided between supporting block 20 and travelling arm 12
Spring 21,21 one end of compressed spring and supporting block 20 are fixed, and the other end and travelling arm 12 are fixed, to utilize the bullet of compressed spring 21
Property potential energy push travelling arm 12, be not necessarily to testing staff's manual toggle travelling arm 12, reach the more convenient technical effect of detection.
Due to having additional compressed spring 21, in the case where being not affected by external force interference, travelling arm 12 and fixed arm 11 are in most
Travelling arm 12 and fixed arm 11 can not be placed in gear ring class part when the state simultaneously, therefore place by remote state
When need that travelling arm 12 is pulled to make it close to fixed arm 11, there are certain inconveniences, thus as shown in figure 3, shell 1 in sliding
It is connected with driving column 22, shell 1 is rotatably connected to control pressing board 23, and 22 one end of driving column is connected to travelling arm 12, and the other end supports

Nearly fixed arm 11 reaches the control more convenient technical effect of travelling arm 12.
It should be noted that as shown in figure 3, control pressing board 23 extends upward shell 1, the fixed setting of 1 upper surface of shell
There is holding ring 24, when needing the utility model to be placed on gear ring class part, testing staff holds holding ring 24, and leads to
Thumb press control pressing board 23 is crossed, to realize the technical effect that can be operated with one hand the utility model.
The gear ring class part of different model, space width are also different, therefore the diameter of the spherosome 17 of its adaptation
It is equally different, adapts to the gear ring class part of different model thus, opened as shown in figure 3, travelling arm 12 and fixed arm 11 run through
Equipped with the spliced eye mating with connecting column 15, connecting column 15 is threadedly engaged hold-doun nut 26, hold-doun nut 26 and cone
16 disc is matched for clamping tightly travelling arm 12 or fixed arm 11；When needing to detect the gear ring class part of different model, will fix
Nut 26 on connecting column 15 by backing out, so that the disassembly of measuring head 14 is unrestricted；After dismantling measuring head 14, taking has accordingly
The measuring head 14 of spherosome 17, and guide its connecting column 15 to pass through spliced eye and tighten hold-doun nut 26, thus by hold-doun nut 26
Cone 16 is cooperated to clamp travelling arm 12 or fixed arm 11；In conclusion by replacement measuring head 14, to adapt to different teeth
The tooth socket of class part is enclosed, and then improves the adaptability of the utility model.
To avoid influencing the accuracy of detection because of the tooth socket deviation that two measuring heads 14 are embedded in, as shown in Fig. 2, gear ring class
Part distance over bar detector further includes spacer pad 27, and 27 both ends of spacer pad are welded with mating with connecting hole 92
Inserting column 28 is positioned, the line direction that spacer pad 27 positions inserting column 28 along two, which is run through, offers stroke groove 29, wherein stroke groove
29 with travelling arm 12,11 clearance fit of fixed arm；First spacer pad 27 is placed on gear ring class part when detecting, at this time
The positioning inserting column 28 at 27 both ends of spacer pad is plugged in respectively in two opposite connecting holes 92 of gear ring class part, thus stroke groove
29 length direction middle line and the midpoint of gear ring class part are in same perpendicular, and then only need travelling arm 12 and fixed arm
11 gaps are embedded in stroke groove 29, that is, can ensure that two measuring heads 14 are respectively embedded into two opposite tooth sockets of gear ring class part,
It effectively prevent influencing the accuracy of detection because of tooth socket deviation.
Specific embodiment is only the explanation to the utility model, is not limitations of the present invention, this field
Technical staff can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but only
It will be in the scope of the claims of the utility model all by the protection of Patent Law.
