Abstract
The utility model provides a kind of cermet piston rod for hydraulic headstock gear, the scale bar with displacement sensor cooperation including piston bar body and on the ontology, described body sidewall upper edge is axially arranged with the groove coordinated with the scale bar, the groove two side is equipped with two limiting slots in an axial direction, the scale bar and the groove plug connection, scale bar both sides are equipped with the limited block coordinated with the limiting slot, and spaced set has scale hole vertically in the face that the scale bar coordinates with sensor.A kind of cermet piston rod for hydraulic headstock gear provided by the utility model after the scale hole abrasion on scale bar, is only needed to change scale bar, economized on resources using scale bar and ontology split settings.
Description
Technical field
The utility model is related to hydraulic headstock gear technical fields, make pottery more particularly to a kind of metal for hydraulic headstock gear
Porcelain piston rod.
Background technology
In the prior art, using slot and sensor cooperation is threaded on piston rod, to make sensor obtain piston rod
Stroke, however, piston rod side wall be equipped with thread groove influence piston rod structural strength, piston rod is not easy to clean, and piston rod is long
Phase use is easy to cause thread groove abrasion, influences to measure quality, need to re-replace whole piston rod, cause to waste.
Utility model content
Technical problem to be solved in the utility model is：It is threaded slot in order to overcome on piston rod in the prior art and leads
The deficiency of cause, the utility model provide a kind of cermet piston rod for hydraulic headstock gear.
The utility model solves its technical problem technical solution to be taken：A kind of metal for hydraulic headstock gear
Ceramic cylinder rod, including piston bar body and the scale bar with displacement sensor cooperation on the ontology, described
Body sidewall upper edge is axially arranged with the groove coordinated with the scale bar, and the groove two side is equipped with two limiting slots, institute in an axial direction
Scale bar and the groove plug connection are stated, scale bar both sides are equipped with the limited block coordinated with the limiting slot, the quarter
Spending the face that bar coordinates with sensor, spaced set has scale hole vertically.
Be arranged on scale bar scale hole be used for displacement sensor conjunction measuring piston rod stroke, scale bar is seperated with ontology
Setting only needs to change scale bar, economizes on resources, the cooperation of limiting slot and limited block makes after the scale hole abrasion on scale bar
Scale bar is completely embedded with ontology, and can ensure piston rod construction intensity.
Further, in order to fix on the body scale bar, scale bar both ends are equipped with the spiral shell with the body fits
Pit, the threaded hole is interior to be equipped with screw.
Further, it is injected on the face that the body outer wall face and the scale bar coordinate with institute displacement sensors
Ceramic coating.
The utility model has the beneficial effects that：A kind of cermet for hydraulic headstock gear provided by the utility model is lived
Stopper rod after the scale hole abrasion on scale bar, is only needed to change scale bar, saves money using scale bar and ontology split settings

Specific implementation mode
The utility model is described in detail presently in connection with attached drawing.This figure is the schematic diagram of simplification, only in a schematic way
Illustrate the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Figs 1-4, a kind of cermet piston rod for hydraulic headstock gear of the utility model, including piston rod
Ontology 1 and the scale bar 2 with displacement sensor cooperation on the ontology 1, the piston rod connect with the sliding of cylinder body 7
It connects, the cylinder body 7 is equipped with displacement sensor 8,8 contact piston bar surface of institute's displacement sensors, 1 side wall upper edge of the ontology
It is axially arranged with the groove 3 coordinated with the scale bar 2,3 two side of the groove is equipped with two limiting slots 4, the scale in an axial direction
Bar 2 and 3 plug connection of the groove, 2 both sides of scale bar are equipped with the limited block 5 coordinated with the limiting slot 4, the scale
Spaced set has scale hole 6 vertically in the face that bar 2 coordinates with sensor.
2 both ends of scale bar are equipped with the threaded hole coordinated with the ontology 1, and screw is equipped in the threaded hole.
It is injected with ceramics on the face of 1 outside wall surface of the ontology and the scale bar 2 and institute's displacement sensors cooperation
Coating.
It is enlightenment, through the above description, relevant work with the above-mentioned desirable embodiment according to the utility model
Personnel can carry out various changes and amendments in without departing from the scope of the utility model completely.This item utility model
Technical scope is not limited to the contents of the specification, it is necessary to determine its technical scope according to right.
