In another example, need detect castor tooth towards upper and lower, left and right, oblique direction offset when, choose electric probe
44 and the quantity of loophole 43 are six.
In the present embodiment, the light that photoelectric probe 44 is sent out can cross loophole 43, shift in castor tooth 30 and drive
When one pipeline 10 also shifts, ring baffle 41 can shift with first pipe 10, at this point, what photoelectric probe 44 occurred
Light part can be blocked by ring baffle 41, by detect the light that sends out of photoelectric probe 44 be it is no be blocked, i.e., optoelectronic switch 70 is
No conducting can judge the offset direction of castor tooth 30.
Referring to Fig. 3, in an optional embodiment, 43 slotted eyes of loophole, the long axis direction of the slotted eye
Radial direction along ring baffle 41 is arranged, and photoelectric probe 44 is set at the outer of slotted eye, that is to say, that photoelectric probe
44 are set to the circle far from ring baffle 41 and at the outer of slotted eye.
, it is understood that by this setup of photoelectric probe 44, when castor tooth 30 shifts, ring baffle
41 also shift therewith, to shelter from the light of the generation of photoelectric probe 44, so as to avoid 41 offset very little of ring baffle
In the case of, the light of the generation of photoelectric probe 44 cannot be sheltered from, and then ensure that the accuracy of measurement.
In one example, loophole 43 and the quantity of photoelectric probe 44 are four, and are uniformly arranged on annular gear respectively
In the circumferential direction of plate 41 and annular mounting plate 42, three optoelectronic switches 70 disconnect wherein, what an optoelectronic switch 70 was connected
In the case of, the offset direction of castor tooth 30 can be accurately judged to.
With continued reference to Fig. 1, regulating member 50 includes that at least three regulation motors 51 and at least three adjust thimble 52, is adjusted
The output axis connection of thimble 52 and regulation motor 51, it is preferred that regulation motor 51 and adjust thimble 52 quantity be three and
Each connection of regulation motor 51 is there are one thimble 52 is adjusted, and certainly, regulation motor 51 and the quantity for adjusting thimble 52 are not limited to three
It is a, it can also be other quantity, there are one adjusting thimbles 52 as long as can ensure a connection of regulation motor 51, and pass through
Regulation motor 51 and adjusting thimble 52 can correct the offset of castor tooth 30.
Regulation motor 51 is uniformly distributed in around castor tooth 30, and regulation motor 51 is connect with controller 60, passes through controller
60 can control to adjust the rotation of motor 51, and then adjust the length of thimble 52 to be corrected to the offset of castor tooth 30.
In one example, it is provided with nut on castor tooth 30, adjusts and is provided with screw thread on thimble 52, adjusts the setting of thimble 52 and exists
It on nut, is driven by the rotation of regulation motor 51 and adjusts the rotation of thimble 52, nut can be screwed in or screw out simultaneously by adjusting thimble 52
Change the offset of castor tooth 30.
In an optional embodiment, monitoring regulating device further includes display device 80, display device 80 and controller
70 connections can show that the direction that castor tooth 30 deflects.
In one example, display device 80 is computer display screen.
Controller provided in an embodiment of the present invention can be that (Programmable Logic Controller, can compile PLC
Journey logic controller), can also be other components with similar logical operation function.
On the other hand, the embodiment of the present invention additionally provides a kind of engine test part castor backlash monitoring method, the party
Method specifically includes following steps：
Obtain the on off operating mode of the first optoelectronic switch, the second optoelectronic switch, third optoelectronic switch and the 4th optoelectronic switch；
If first optoelectronic switch disconnects, and second optoelectronic switch disconnects, and the third optoelectronic switch
Conducting, and the 4th optoelectronic switch disconnects, then and the direction of the castor tooth towards first optoelectronic switch shifts；
If the first optoelectronic switch conducting, and second optoelectronic switch disconnects, and the third optoelectronic switch
It disconnects, and the 4th optoelectronic switch disconnects, then the direction of the castor tooth towards the third optoelectronic switch shifts；
