Description
Technical field
The invention belongs to hydraulic machinery structure technology, it is related to rotating the auxiliary valve core detection structure of direct drive servovalve.
Background technique
In existing hydraulic machinery rotation direct drive servovalve structure, clutch configuration, main valve are added using major-minor spool
Wick-like state has electrical path real time monitoring, and auxiliary valve core and clutch do not have electrical path monitoring, it may occur however that stuck but to examine
It surveys, remaining is caused to fail.
Summary of the invention
The purpose of the present invention is: propose an auxiliary valve core detection design structure, can periodic detection auxiliary valve core it is whether stuck,
Improve the maintainability and reliability of rotation direct drive servovalve.
The technical scheme is that the auxiliary valve core detection structure of rotation direct drive servovalve；It is characterized in that, by examining
It surveys rocker arm (1), detects compression bar (2), detect gland (3), detect pressing plate (4), insurance safety pin (5) composition, detection rocker arm (1) suit
On auxiliary valve core；Detection gland (3) covers in detection compression bar (2), and detection compression bar (2) end and detection pressing plate (4) are connected；Detection
Seal groove (2a) and insurance hole are provided on compression bar (2), insurance safety pin (5) is through in insurance hole；It is equipped at valve body place to be detected
Threaded hole with the unthreaded hole of detection compression bar (2) and with detection gland (3) cooperation.
The invention has the advantages that can periodic detection auxiliary valve core and clutch state, simplicity be easy to outfield operation, improve
The maintainability of product, it is ensured that mechanical two remainings of major-minor spool it is normal.
Detailed description of the invention
Fig. 1 is the schematic diagram of auxiliary valve core detection structure and major-minor spool,
Fig. 2 is the rotation direct drive servovalve sectional view using auxiliary valve core detection structure,
Number explanation: 1- detects rocker arm, and 2- detects compression bar, and 3- detects gland, and 4- detects pressing plate, and 5- insures safety pin, 6- master
Spool, 7- auxiliary valve core.
Specific embodiment
The present invention is described in further details below.Referring to Fig. 1,2, the auxiliary valve core detection of direct drive servovalve is rotated
Structure rotates the auxiliary valve core detection structure of direct drive servovalve including one.It by detection rocker arm (1), detects compression bar (2), inspection
It surveys gland (3), detects pressing plate (4), insurance safety pin (5) composition, detection rocker arm (1) is sleeved on auxiliary valve core；Detect gland (3) set
In detection compression bar (2), detection compression bar (2) end and detection pressing plate (4) are connected；Seal groove is provided in detection compression bar (2)
(2a) and insurance hole, insurance safety pin (5) are through in insurance hole；Valve body place to be detected be equipped with detection compression bar (2) unthreaded hole with
And the threaded hole with detection gland (3) cooperation.
On the basis of above structure, pressing plate (4) are detected in order to prevent and detection gland (3) loosens, in detection pressing plate
(4), it detects and is additionally provided with fuse hole in gland (3) and detection compression bar (2), it is locking by fuse.
On the basis of above structure, detection compression bar (2) stainless steel material good using wearability can increase making for structure
With the service life, while preventing the oil leak generated by abrasion.
The working principle of the invention is: when detection, removing insurance safety pin, pressing detection pressing plate and Pen-down detection compression bar, pushes away
Dynamic detection rocker arm rotation, drives auxiliary valve core rotation.It presses and shows that auxiliary valve core rotation is normal on earth；After loosing one's grip, detection compression bar rebound
Show that auxiliary valve core arrangement of clutch is normal.Detection finishes, installation insurance safety pin, and detection components is avoided to interfere the normal work of major-minor spool
Make.
