Abstract
The invention belongs to the auxiliary debugging technology of a multitandem valve displacement sensor, and particularly relates to sensor position precision debugging. In the debugging process of a multitandem valve sensor of an excavator, when a sensor iron core is loosened and locked, because a valve element can rotate by 360 degrees, during each-time debugging, a spring cover on the other side needs to be detached, the debugging process is inconvenient, and the efficiency is low. In order to solve the problems, two process holes are machined in the end face of the valve element in a debugging manner, a dedicated wrench with a small pin is used for positioning, in the debugging process, when a locking nut is dismounted and mounted, a spring cover on the other end does not need to be detached, the dismounting and mounting frequency is reduced, debugging is convenient and rapid, and work efficiency is improved.
Description
Technical field
The invention belongs to banked direction control valves displacement transducer assistant adjustment technology, be specifically related to the tune of a kind of sensing station precision
Examination.
Background technology
Excavator banked direction control valves sensor is arranged on spool, and for detecting the displacement of spool, the movement of spool is directly controlled
Making the whole operation action of excavator, sensor realizes the closed loop control of banked direction control valves for the position feeding back spool, is excavating
In machine valve core of multiway valve, installation site sensor belongs to the innovation first of domestic project machinery.
During the debugging of excavator banked direction control valves sensor, when loosening with lock sensor iron core, because spool is permissible
The rotation of 360 degree, causes debugging every time and will pull down other spring shield, bring inconvenience to debugging process, and efficiency is low
Under.
Summary of the invention
The technical problem to be solved is: facilitate excavator valve core of multiway valve sensor plunger position debugging and
Locking.
The displacement transducer location structure for hydraulic efficiency slide valve spool of the present invention, has screwed hole in the right side of spool
And fabrication hole, threadeded with described screwed hole, and locked by double nut in one end of sensor iron core；Described fabrication hole has two
Individual, during adjusting sensor plunger position, by the two of special spanner pins being inserted in described fabrication hole control
Spool processed is relative to the rotation of valve pocket, thus remains the spring other end at described spool.
One of them pin of described special spanner can trace regulation.
Beneficial effects of the present invention: propose spool end processing and debugging fabrication hole two, thus can use specially
The spanner with little pin location so that debugging process dismounting locking nut time, other end spring shield need not be pulled down, decrease
Dismounting number of times, debugs convenient and swift, improves work efficiency.
1, reduce labor intensity and be previously required to the most greatly two people's cooperations, in addition it is also necessary to pull down the spring shield of the other end, many
Repeatedly, being improved as, it is only necessary to pull down sensor one end, a people completes whole debugging process；
2, improving work efficiency obvious, one 7 sensor of debugging were accomplished by for one and half working days in the past, shortened to debugging
One has only to 1 hour time the most shorter.

Detailed description of the invention
A kind of displacement transducer location structure for hydraulic efficiency slide valve spool, have in the right side of spool 5 screwed hole and
Fabrication hole 3, is threadeded with described screwed hole, and is locked by double nut in one end of sensor iron core 4；Described fabrication hole 3 has
Two, during adjusting sensor iron core 4 position, by the two of special spanner 7 pins 6 are inserted into described fabrication hole
Control the spool 5 rotation relative to valve pocket 2 in 3, thus remain the spring 1 other end at described spool 5.
One of them pin 6 of described special spanner 7 can trace regulation.
During debugging, when loosening with lock sensor iron core 4, in auxiliary with special spanner 7 and outer hexagon, shape
Become the torsional forces that rotation is relative, it is achieved that loosening and locking of sensor iron core 4, it is to avoid because spool 5 can with 360 degree
Rotate, it is to avoid the loosening puzzlement brought with locking of sensor.
It is embodied as process step described below:
Step 1: pull down pickup wire ladle cover；
Step 2: be matched with the fabrication hole 3 of spool 5 correspondence with the pin 6 of special spanner 7；
Step 3: loosen the locking nut on sensor iron core 4 with general utility wrench 7, prevent spool with special spanner 7 simultaneously
Rotate；
Step 4: after having debugged, realizes nut check by the opposite direction of step 3；
Step 5: install the realization debugging of pickup wire ladle cover and tentatively complete.
