The purpose of the present invention and its technical problem underlying is solved using following technical scheme to realize：A kind of chain survey
Dynamometry adjustable flexibility control mechanism on leader, includes the inductive switch and measuring rod on top, and inductive switch front end is equipped with induction
Piece, sensing chip are mounted on measuring rod connecting seat front end, and measuring rod connecting seat upper end is equipped with shaft, lower end is equipped with measuring rod, surveys
Front end is equipped with compression spring and blind nut in the middle part of gauge rod connecting seat.
The measuring rod has different size, is connected on measuring rod connecting seat, realizes that the chain of different, more specifications is surveyed
Amount or other similar measurements.
Utilize the control method of the dynamometry adjustable flexibility control mechanism on a kind of above-mentioned chain gauging machine：Motor drives entire
Component is moved to chain drum direction, to make measuring rod be moved to chain drum direction, when measuring rod moves to and chain drum
When contact, motor does not receive halt instruction and works on, and drives measuring rod to continue to move to chain drum direction, due to chain
Roller is relatively motionless, and therefore, measuring rod drives measuring rod connecting seat to be rotated to the opposite direction of chain drum by shaft, measures
Bar connecting seat drives the upper end of sensing chip to rotate close inductive switch to inductive switch direction again；Inductive switch senses signal
When, that is, motor stalls are controlled, but motor cannot power off at this time, keep current location status, with the current measurement of stabilization
Power, meanwhile, system acquisition current raster coordinate measures gathered data；In order to eliminate the gap between chain drum and axis pin, lead to
The elastic force that blind nut adjusts compression spring is crossed, to control the size that measuring rod contacts chain drum contact force, is no longer adjusted in measurement process
Section, ensure that stable repeatability precision；By designing various forms of measuring rods, it is connected on measuring rod connecting seat, it can be with
Chain measurement or other the similar measurement purposes for realizing different, more specifications, make the measuring mechanism become survey flexible
Amount system.
The present invention has clear advantage and advantageous effect compared with prior art.By above technical scheme it is found that this hair
It is bright to have the characteristics that：
1）, motor drive entire component to be moved to chain drum direction, when measuring rod, which is moved to, to be contacted with chain drum, motor is not
It receives halt instruction to work on, measuring rod is driven to continue to move to chain drum direction, measuring rod drives measuring rod connection
Seat is rotated by shaft to the opposite direction of chain drum, and measuring rod connecting seat drives the upper end of sensing chip to inductive switch side again
To the close inductive switch of rotation；When inductive switch senses signal, that is, motor stalls controlling, motor does not power off at this time,
Current location status is kept, with the current measuring force of stabilization, meanwhile, system acquisition current raster coordinate reaches measurement acquisition
The purpose of data, this is a feature of the present invention.
2）, another feature of the present invention be：Measuring force is precisely controlled.In order to eliminate between chain drum and axis pin
Gap, the elastic force that compression spring can be adjusted by blind nut reach elimination to control the size that measuring rod contacts chain drum contact force
Gap purpose between chain drum and axis pin is no longer adjusted in measurement process, to ensure stable repeatability precision.
3）, the present invention third feature be：Due to the presence of two above feature, the measuring mechanism is made to become flexible
Measuring system, to allow this set mechanism to measure smaller chain（Measuring rod can be designed very little）.It is different by designing
The measuring rod of form is connected on measuring rod connecting seat, and the chain that different, more specifications may be implemented measures or other are similar
Measurement purpose.
